Guest guest Posted September 20, 2010 Report Share Posted September 20, 2010 Low oxalate diettake calcium OR magnesium prior to mealtimes (this is not to be considered your supplement, it is being used to bind to oxalate; your supplement, be it mag or cal, should be taken away from mealtime for the actual supplementation/absorption), consume higher dose biotin, use VSL#3 if you can (it contains strept strain and milk I believe) I purchased Custom Probiotics 11 strain b/c it does not contain strept but most of the same probiotics as VSL#3 (VSL#3 has been laboratory proven to degrade oxalate) --- ToniTo: mb12 valtrex Sent: Mon, September 20, 2010 7:53:13 AMSubject: Oxalates What's is the best way to decrease oxalates and oxaditative stress Sent from my iPod Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 20, 2010 Report Share Posted September 20, 2010 Rhonda, Oxalates themselves cause an enormous amount of oxidative stress and lipid peroxidation, depleting glutathione, and shutting down the energy metabolism in cells where oxalate gets into the mitochondrion. For more info on this, see the studies I've put below on oxalate's effects on red blood cells and the mitochondrion and the kidney. I've recently gone to the primary hyperoxaluria conference in NYC where they discussed the genetic condition where an enzyme defect makes their liver churn out high levels of excess oxalate and there, I found autism. The field is RUN by kidney doctors who only start treating these patients after they get in kidney failure, but they have failed to recognize other things that happen in these patients earlier. Included there would be horrible GI problems and GI pain, bone pain, and according to one doctor I talked to from Canada, a list of the same conditions we see getting better on the low oxalate diet outside autism, like fibromyalgia, interstitial cystitis, and vulvodynia. They had a mixer where the people at the patient conference could mingle with the scientists who attended the scientific conference, so in talking to the families and to the only person who has done a clinical study on a large group of these patients, I learned about undocumented autism that seems it could be common in this genetic disease. (There are only about 500 cases of primary hyperoxaluria that have been identified in the whole world. Because of their gene defect oxalate levels in blood and urine and tissues soar.) The first family I met had a son with primary oxaluria who had OCD and Aspergers. The next family with a toddler had an uncle with autism and the mother had hydrocephalus. That was striking to me because one of the most dramatic improvements on the diet has been a child with autism who had failed to develop past infancy and had hydrocephalus and was given a shunt, but his development arrested there. He only began " infant " development at age five once he was on the diet. A fifteen or so year old boy sat by himself at my table and never looked up as I got up, sat down, got up over and over again, but he was immersed in a game toy he was playing with during the whole hour and a half of the party. That seemed " spectrumish " to me, although I didn't talk to him since I never got eye contact. Later, I had lunch with a scientist who is developing the orphan drug probiotic oxalobacter formigenes. She has been doing Phase II and III drug trials on this product which is the only treatment study that has ever been done in primary hyperoxaluria aimed at reducing oxalate. When I told her all the families I had met that seemed to have autism in the family, she said, " Oh yes. They are not normal. " (She's a microbiologist...so you wouldn't expect her to be able to diagnose autism, but what she said told me that the kidney doctors also had been ignoring this issue, just like doctors and psychiatrists for so many years ignored the GI issues in autism.) Rhonda, our listserve has had people with other genetic diseases comorbid with autism that have genetic reasons for gut permeability and their autism symptoms have improved on the diet just like the " regular " autism kids. There may be polymorphisms for oxalate issues that increase risks of not being able to " handle " oxalate. A study in France found that most patients given a drug that contains large amounts of oxalate developed neurotoxicity, but the level of neurotoxicity appeared to be determined by the presence or absence of a polymorphism in the AGT gene, which is the B6 dependent gene that causes primary hyperoxaluria. I hope we can do a genetic study like theirs in the autism population. Why was the autism and why have their GI issues and metabolic issues been ignored in primary hyperoxaluria? There was a complaint at the conference from a scientist who had done mouse studies that the " field " was ignoring the rest of the body and especially the blow that oxalate makes on the general metabolism, and the lack of treatments beyond liver transplants. I talked to him and gave him the good news that the Autism Oxalate Project at ARI HAS developed treatments that aide in the detoxification of oxalate. It is when detoxing oxalate that you see the worst symptoms, both in autism and in primary hyperoxaluria after they have a transplant. The detox process occurs in the body in earnest ONLY AFTER the sources of excess oxalate have been reduced...such as diet, and correcting vitamin deficiencies that lead to our cells making oxalate. The biggest issue on the vitamin front is pyridoxine (vitamin B6). Bernie Rimland studied B6 and magnesium therapy in autism for decades but he didn't know that these nutrients are critical to keep people from making oxalate metabolically. Enzymes that handle oxalate function in an organelle called the peroxisome, but until that enzyme binds B6, it cannot be imported into the peroxisome, so it cannot work properly. A scientist at the conference reported there is one mutation in primary hyperoxaluria where they found giving 400-600 mgs of pyridoxine a day pretty much solved the oxalate problem in that group! That's higher amount of B6 than anyone has gone for studying its effects in autism. So Rhonda, you asked a simple question, but the answer involves much more than Toni offered, though what she said was good. What Toni mentioned will help in reducing how much oxalate you absorb, but on our listserve I get into the particulars of which supplements have been documented as reducing the oxidative stress that comes from oxalate's effects on cells. There was lots in the literature to help us and it is incorporated into the recommendations I make on the listserve. Oxalate knocks out every important complex in the electron transport chain, at the same time as compromising glycolysis, gluconeogenesis, and the TCA cycle because of other enzymes it knocks out. Mitochondrial scientists do not know this literature as I learned while attending the United Mitochondrial Disease Foundation meeting this summer. Oxalate knocks out the enzyme that uses pyruvate to make citrate at the entrance into the Krebs cycle. People with high oxalate tend to be low citrate, and correcting the citrate will help reduce oxidative stress as the article below states! This is why the preferred form of calcium used is calcium citrate. If you want to know more, join our listserve where we discuss all this and have great helps for " newbies " . I do not recommend people reducing oxalate without getting the benefit of the discussions on our listserve where you get the latest science as it happens. I cannot tell you how many people come to our listserve saying they've been LOD, but they were not getting the information they needed to get the results that they did get once they joined. This has happened because DAN! has not provided access for me to train ANY of the nutritionists/dieticians in Defeat Autism Now! that are trying to train others or advice patients on how to use the diet. Unfortunately, the ones who are giving out advice on LOD don't know what they don't know! Hum Exp Toxicol. 2009 Apr;28(4):245-51. Oxalate-mediated oxidant-antioxidant imbalance in erythrocytes: role of N-acetylcysteine. Bijarnia RK, Kaur T, Singla SK, Tandon C. Department of Biotechnology and Bioinformatics, Jaypee University of Information Technology, Waknaghat, India. Abstract The present in-vivo study was to observe the effect of N-acetylcysteine (NAC) on oxalate-induced oxidative stress on rat erythrocytes. A total of 15 Wistar rats were divided into three groups. The control group received normal saline by single intraperitoneal injection. Hyperoxaluria was induced by single intraperitoneal (i.p.) dose of sodium oxalate (70 mg/kg body weight in 0.5 mL saline) to a second group. The third group was administered single i.p. dose of NAC according to 200 mg/kg body weight dissolved in 0.5 mL saline, half an hour after oxalate dose. NAC administration normalized antioxidant enzyme activities (superoxide dismutase and catalase) and reduced malondialdehyde content (indicator of lipid peroxidation) in hyperoxaluric rat's red blood cell (RBC) lysate. NAC administration also resulted in a significant improvement of thiol content in RBC lysate via increasing reduced glutathione content and maintaining its redox status. Oxalate-caused alteration of cholesterol/phospholipid ratio (determining membrane fluidity) was also rebalanced by NAC administration. Further, after NAC administration, electron microscopy showed improved cell morphology presenting its prophylactic properties. Above results indicate that NAC treatment is associated with an increase in plasma antioxidant capacity and a reduction in the susceptibility of erythrocyte membranes to oxidation. Thus, the study presents positive pharmacological implications of NAC against oxalate-mediated impairment of erythrocytes. PMID: 19734276 Eur J Pharmacol. 2008 Jan 28;579(1-3):330-6.

Department of Medical Biochemistry, Dr. ALM. Post Graduate Institute of Basic Medical Sciences, University of Madras, Taramani Campus, Chennai - 600 113, India. Abstract Oxalate/calcium oxalate toxicity is mediated through generation of reactive oxygen species in a process that partly depends upon events that induce mitochondrial damage. Mitochondrial dysfunction is an important event favoring stone formation. The objective of the present study was to investigate whether mitochondria is a target for oxalate/calcium oxalate and the plausible role of naturally occurring glycosaminoglycans from edible seaweed, fucoidan in ameliorating mitochondrial damage. Male albino rats of Wistar strain were divided into four groups and treated as follows: Group I: vehicle treated control, Group II: hyperoxaluria was induced with 0.75% ethylene glycol in drinking water for 28 days, Group III: fucoidan from F. vesiculosus (5 mg/kg b.wt, s.c) from the 8th day of the experimental period, Group IV: ethylene glycol+fucoidan treated rats. The tricarboxylic acid (TCA) cycle enzymes like succinate dehydrogenase, isocitrate dehydrogenase, malate dehydrogenase and respiratory complex enzyme activities were assessed to evaluate mitochondrial function. Oxidative stress was assessed based on the activities of antioxidant enzymes, level of reactive oxygen species, lipid peroxidation and reduced glutathione. Mitochondrial swelling was also analyzed. Ultra structural changes in renal tissue were analyzed with electron microscope. Hyperoxaluria induced a decrease in the activities of TCA cycle enzymes and respiratory complex enzymes. The oxidative stress was evident by the decrease in antioxidant enzymes, glutathione and an increase in reactive species and lipid peroxidation in mitochondria. Mitochondrial damage was evident by increased mitochondrial swelling. Administration of fucoidan, decreased reactive oxygen species, lipid peroxidation (P<0.05), mitochondrial swelling and increased the activities of antioxidant enzymes and glutathione levels (P<0.05) and normalized the activities of mitochondrial TCA cycle and respiratory complex enzymes (P<0.05). From the present study, it can be concluded that mitochondrial damage is an essential event in hyperoxaluria, and fucoidan was able to effectively prevent it and thereby the renal damage in hyperoxaluria.

Department of Pathology, Immunology and Laboratory Medicine, University of Florida, Gainesville, Florida 32610-0275, USA. Abstract PURPOSE: Oxalate and calcium oxalate (CaOx) crystals are injurious to renal epithelial cells. The injury is caused by the production of reactive oxygen species (ROS). Citrate is a well-known inhibitor of CaOx crystallization and as such it is one of the major therapeutic agents prescribed. Since citrate increases cellular reduced nicotinamide adenine dinucleotide phosphate and glutathione (GSH), we hypothesized that exogenously administered citrate should act as an antioxidant and protect cells from oxalate induced injury. MATERIALS AND METHODS: We exposed LLC-PK1 and MDCK cells to 500 microM/ml oxalate or 150 mug/cm calcium oxalate crystals for 30, 60 and 180 minutes with or without 3 mg/ml citrate in the medium. We determined cell viability by lactate dehydrogenase release and trypan blue exclusion, ROS involvement by changes in hydrogen peroxide and GSH, and lipid peroxidation by quantifying 8-isoprostane. RESULTS: The presence of citrate was associated with significant decrease in lactate dehydrogenase release (p <0.001) and staining with trypan blue (p <0.05). In addition, there was a significant increase in GSH (p <0.005) and a decrease in the production of hydrogen peroxide (p <0.05) and 8-isoprostane (p <0.0005) secretion into the culture medium when citrate was present in the medium. CONCLUSIONS: Citrate protects cells from oxalate and CaOx crystal induced injury by preventing lipid peroxidation through a decrease in ROS production. The results provide additional data for the beneficial role of citrate therapy for CaOx nephrolithiasis.

Guest guest Posted September 20, 2010 Report Share Posted September 20, 2010 Oxalates rise in response to yeast overgrowth. Reduce yeast and the oxalates will follow. I once read a study that suggested reducing them without dealing with the underlying problem isn't recommended, because the oxalate rise has to do with something in the body working to protect itself. I don't remember the details, because the study was very hard to read (blurry copy) so I only go bits and pieces of it. I think it was from the Autism One conference. We have never attempted to reduce our son's oxalates, we just work to treat the underlying cause of the yeast and bacteria overgrowth. > > What's is the best way to decrease oxalates and oxaditative stress > > Sent from my iPod > Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 20, 2010 Report Share Posted September 20, 2010 I didn't read this whole thing, just had time to skim it, but I wonder if anyone addressed the possibility of heavy metals at the root of these things. With heavy metals comes high pathogenic loads and when you test an individual, their yeast and bacteria loads tend to correlate to their oxalate levels. I am sure there are other disorders out there that may not relate to this at all, but when you connect the autism link, high pathogenic loads are ALWAYS involved, so are heavy metals....just a thought!

Guest guest Posted September 20, 2010 Report Share Posted September 20, 2010 I don't know the specifics, that is 's arena, but metals bond to oxalate. And the converse can also be said, reduce oxalate, and you may see the metals go bye bye, without need for "chelation.", I didn't mention the B6 because high B6 will increase phenol sensitivity, I thought, but P5P does not do this.... didn't know the reasons and I didn't want to have to expand on it, other than the B6 impairs some enzyme. Also, many of the people here are using B6 or P5P, I don't want them to think that is all they need to do to work on their oxalate issue. FWIW, there is a steep learning curve to this diet, if you want to ramp up to it, start now.

Guest guest Posted September 20, 2010 Report Share Posted September 20, 2010 , There is ABSOLUTELY no evidence that yeast infections produce physiologically relevant levels of oxalate no matter what you heard at AutismOne. This was conjecture. I think the paper you read was a blog post that I also had people send to me, and it was also conjecture. There is unfortunately no science to support it. Just look in pubmed! No scientist has found that the body makes oxalate in response to any condition except vitamin deficiencies that ruin the regulation of the enzymes designed to protect us from the toxicity of oxalate that comes from food. B6 is one of those vitamins, as is thiamine. What is known is that yeast can make a precursor to oxalate from arabinose called d-erythroascorbic acid, and it puts you at the same risk for making oxalate as taking vitamin C...no more, no less. That conversion is more or less the same conversion. Yeast won't use arabinose as food unless other forms of sugar are not available. Using arabinose is a stress reaction for yeast. Check the literature! At this conference I attended, one scientist reported that ordinary commensal bacteria only degrade oxalate in the gut if their normal food is not available, like in a stress response. This may be why the " anti-candida diet " that reduces sugar may persuade microbes in the gut to degrade oxalate that would ordinarily leave oxalate alone. Changes in the diet aimed at " killing yeast " may have worked actually by stressing bacteria so that they degraded oxalate! The only fungal infection that has been noted to produce damaging amounts of oxalate is aspergillus infections of the lung which have huge fungal balls in the lungs that can be detected. Nothing subtle. I've had multiple conversations with Bill Shaw about this. If large enough amounts of oxalate were produced by yeast, then recognition of oxalate issues in patients with candidiasis that is fatal or near-fatal would have been noted in the literature! It is not there. > > > > What's is the best way to decrease oxalates and oxaditative stress > > > > Sent from my iPod > > > Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 20, 2010 Report Share Posted September 20, 2010 , I think you skimmed too quickly! I was reporting on people who are known to have A GENE DEFECT that causes them to MAKE oxalate that goes all over the body. Their oxalate is not a secondary condition to anything. You've mentioned people who are suggesting that oxalate is a secondary issue to some other things seen in autism, but our experience and that of the Vulvar Pain Foundation is that the arrow is likely going the other direction! Many on LOD lose the need for treatments for yeast and treatment of heavy metals without using the medicines or supplements. Once the diet has worked in this area, it seems to be a more or less permanent change. Even before our project started, we heard that the Vulvar Pain Foundation noticed that their members with chronic yeast issues also lost their chronic yeast problems on the diet and tendency to urinary tract infections and no longer needed ANY treatment for these issues after they had experienced sometimes decades of treatment. It is so hard to shift models when people have been thinking so hard that the causation arrow goes one way, when an ASSOCIATION does not tell you which part of that association came first. Even among scientists where I spend most of my time, what people already believe (doctrine that never had proof in the first place) ends up being the biggest block to learning or grasping the significance of something new. This is exactly what kept the kidney doctors from recognizing the autistic tendencies in primary hyperoxaluia patients BECAUSE they believed without proof that oxalate damaged the kidneys before it could damage the rest of the body. Because of this they ignored the other issues that were already in their patients, like their GI issues, their fibromyalgia, their interstitial cystitis, and apparently, their autism. They never dreamed these issues were related to oxalate! Previous models about yeast and heavy metals have kept many people from listening to how different the oxalate issue is from previous models. Some people only listened long enough to get a " sound bite " and then ran off in their own direction advancing theories as if they were facts. Be careful to notice who has references and which points are referenced by scientific studies and which are not! People on my listserve know I am a bear about furnishing references, for I want people to know what has the solid backing of clinical and basic science research. Treating yeast is not news in autism. I was there fifteen years ago when Bill Shaw first presented his theories on yeast to the first DAN! conference and talked about anti-fungal therapy. I was a graduate student at the time. DAN! has done this sort of treatment ever since then, but the recurring problems with yeast didn't go away with treatment and it wasn't long before the same scenario had to be repeated again. If treating yeast would solve the oxalate issue, then we wouldn't have those who went on the anti-fungal parade and got only better during treatment and then crashed off treatment, and never got rid of the tendency to NEED treatment, but who after this went on LOD and lost the need for antifungal treatment and improved in other areas as well. The same thing happened at the Vulvar Pain Foundation. Women who experienced chronic yeast lost that tendency on the low oxalate diet. Why? There is an easy explanation. Oxalate impairs carboxylase activity. That loss makes it difficult for the body to keep yeast within normal bounds. This is why those with several different genetic defects that all impair carboxylase issues ALSO have yeast problems. That's in the literature and it makes sense why after being on reduced oxalates, yeast issues that were caused by oxalate go away. Better science tells us not what will keep patients dependent on supplements and medicines for the rest of their life, but it tells us how to get their bodies to heal and regain independence! For anyone who had a child who regressed, identifying the mechanism of the regression will point to a solution that should get the child back to normal where he won't need the props. The count of the biomedical treatments that are necessary right now in a child is a pretty good measure of the distance someone is from finding and solving the PRIMARY problem. You can chase secondary problems until you are blue in the face and until the child feels like he will never be independent of all this stuff. I recently talked with a mom of a little girl who was one of our early people on the low oxalate diet. At one time her school district called this girl 67% impaired. This now pre-teen young lady not only lost her diagnosis of autism years ago after about two years on LOD, but she lost the need for special education or accommodation at school. This summer she went to a primitive scout camp for two weeks with no supplements, and had a BLAST. In fact, now she has for several months had no supplements at all. Her mother was scared to stop the supplements that we recommend on LOD, but becoming independent of all the pills and micromanagement had become a passion for this child. This young lady is so proud of losing the burden of all that intervention and now she can start to feel normal! So far, it is working and the mother keeps being astonished at how her daughter is planning ahead, venturing into unknown territory, exploring friendships, and discovering her own heart, etc. The mark of finding the culprit is when what you have done to fix something really fixes it and puts you in a position to lose the need for boatloads of supplements and all the doctors and all the chasing after each year's new autism intervention! > > I didn't read this whole thing, just had time to skim it, but I wonder if anyone addressed the possibility of heavy metals at the root of these things.

Guest guest Posted September 20, 2010 Report Share Posted September 20, 2010 Toni, Oxalate binds both lead and mercury and makes the body RETAIN them in a highly insoluble form. If your blood is high in oxalate BEFORE your exposure to these metals, then oxalate may compromise your ability to excrete these metals. The kidneys are where you have a high concentration of metals collecting and high concentrations of oxalate and they are where most chelators work. But if metals are bound to oxalate, they are not likely to be impairing enzymes, although the oxalate that bound them could be in the company of other oxalate that is free and impairing a long list of enzymes. Years ago, a DAN! doctor in Spain, Dr. Jesus Clavera started putting all her autism patients on reduced oxalate diets and found that the same chelation program she had been using on them for sometimes years was suddenly producing (after the diet) such higher elevations of metal excretions that she was worried about it and reduced the chelating agents in fear that the higher levels being excreted would cause harm. Because oxalate that is in BLOOD may change the way the kidney secretes fluids and adjusts pH, that means changes on any urine tests that are reported ratioed to creatinine can be misleading if no one notices whether and WHEN the analytes as a group shift down or up. You cannot tell if that shift has occurred in a Metals test done in isolation because there are no normal ranges for these toxins. This is why I studied 224 Great Plains organic acid tests collected over a period of about ten years. In that group, there was only one boy in which repeat tests did not show shifts in average urine concentration that were as great as three-fold over repeat tests. This shift, if it is as common in autism as it appears to be from this database, should effect the interpretation of all urine tests ratioed to creatinine including metals tests. I presented on this problem to the thinktank a couple of years ago. In other words, something shifts the ratio of creatinine to water and everything else in the urine, and a big suspect is oxalate that is being detoxified by the body, so moving from blood into the kidney for excretion. Let me give you an example. A parent sent me two organic acid tests done twelve hours apart on her son. When I asked her why the two tests were so close together, she told me the test was repeated after he was given a vitamin C IV and ended up in a metabolic crisis hours later that landed him in the Emergency Room. His oxalate level (vitamin C converts to oxalate in high amounts) had increased about twenty-fold in those hours, but his overall urine concentration of all the analytes on the test dropped three-fold in the twelve hours between the two tests. In other words, the analytes that shift in response to oxalate's enzyme inhibition in the mitochondrion were dramatically different, about a third way higher (as much as forty times higher), and a different third had dramatically shifted down in ways that could be understood by how oxalate impairs certain enzymes. After calculating the shift in the AVERAGE concentration, the other analytes were completely stable that wouldn't be affected by oxalate getting into the mitochondrion of cells. What was so shocking is that the effect of the higher oxalate in his blood would have made a metals test done at the same time look like the metals had fallen three fold! This is why I always recommend someone do an organic acid test at the same time as a metals test so that you can calculate that shift as I always do now on organic acid tests. Making this correction is how I've found a lot of children with fatty acid disorders and other things that the doctor didn't see from the " shifted " report. Tony, vitamin B6 is critical to the oxalate-protecting metabolism and also to the sulfur chemistry in helping us make sulfate and taurine. The lack of sulfate is what leads to PST problems, as they were studied by Dr. Rosemary Waring at the University of Birmingham in England many years ago. If anyone need more info on that, I suggest they read the archives on sulfurstories, a yahoogroup I set up after speaking on sulfur at DAN! conferences to the science and in another year to the regular sessions many years ago. One of those times was right after 9/11! > > > > > > What's is the best way to decrease oxalates and oxaditative stress > > > > > > Sent from my iPod > > > > > > Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 20, 2010 Report Share Posted September 20, 2010 Thank you , Does this child still need the diet, even if she is off of the supplements? And if so, what then gets to the root of the problem, chelation?

So what would you be looking for in an OAT and what would it mean? I had one done when we started this with our son. He's not autistic, but his health mirrors that of an autistic and he has anxiety/yeast/bacteria/probably viral problems/GI disturbances/SPD. Our two year old has never been tested, but he seems pretty similar in many ways. How does all of this relate to the many children who have been recovered with slow oral dose chelation (Andy Cutler)? They don't need diets, supplements, treatments, etc. And then there is the topic of recovery by homeopathy which seems to be pretty popular and successful too. It all just makes my head spin, how can there be so many directions which you can address the same problems, or are they not the same in the end? > > > > > > > > What's is the best way to decrease oxalates and oxaditative stress > > > > > > > > Sent from my iPod > > > > > > > > > > Quote Link to comment Share on other sites More sharing options...

Fascinating to me right now as my son was just diagnosed with pyrroluria -so his body dumps out all of his B6 and Zinc, therefore with no B6 he is then in a bad situation with oxalates, I see. He was just diagnosed with a Long Chain Fatty Acid defect and now it looks like Mito deficiency partial complex I and III....I wonder how much of this mess is all about oxalates?

For more info on this, see the studies I've put below on oxalate's effects on red blood cells and the mitochondrion and the kidney.I've recently gone to the primary hyperoxaluria conference in NYC where they discussed the genetic condition where an enzyme defect makes their liver churn out high levels of excess oxalate and there, I found autism.The field is RUN by kidney doctors who only start treating these patients after they get in kidney failure, but they have failed to recognize other things that happen in these patients earlier. Included there would be horrible GI problems and GI pain, bone pain, and according to one doctor I talked to from Canada, a list of the same conditions we see getting better on the low oxalate diet outside autism, like fibromyalgia, interstitial cystitis, and vulvodynia.They had a mixer where the people at the patient conference could mingle with the scientists who attended the scientific conference, so in talking to the families and to the only person who has done a clinical study on a large group of these patients, I learned about undocumented autism that seems it could be common in this genetic disease. (There are only about 500 cases of primary hyperoxaluria that have been identified in the whole world. Because of their gene defect oxalate levels in blood and urine and tissues soar.) The first family I met had a son with primary oxaluria who had OCD and Aspergers. The next family with a toddler had an uncle with autism and the mother had hydrocephalus. That was striking to me because one of the most dramatic improvements on the diet has been a child with autism who had failed to develop past infancy and had hydrocephalus and was given a shunt, but his development arrested there. He only began "infant" development at age five once he was on the diet.A fifteen or so year old boy sat by himself at my table and never looked up as I got up, sat down, got up over and over again, but he was immersed in a game toy he was playing with during the whole hour and a half of the party. That seemed "spectrumish" to me, although I didn't talk to him since I never got eye contact. Later, I had lunch with a scientist who is developing the orphan drug probiotic oxalobacter formigenes. She has been doing Phase II and III drug trials on this product which is the only treatment study that has ever been done in primary hyperoxaluria aimed at reducing oxalate. When I told her all the families I had met that seemed to have autism in the family, she said, "Oh yes. They are not normal." (She's a microbiologist...so you wouldn't expect her to be able to diagnose autism, but what she said told me that the kidney doctors also had been ignoring this issue, just like doctors and psychiatrists for so many years ignored the GI issues in autism.)Rhonda, our listserve has had people with other genetic diseases comorbid with autism that have genetic reasons for gut permeability and their autism symptoms have improved on the diet just like the "regular" autism kids.There may be polymorphisms for oxalate issues that increase risks of not being able to "handle" oxalate. A study in France found that most patients given a drug that contains large amounts of oxalate developed neurotoxicity, but the level of neurotoxicity appeared to be determined by the presence or absence of a polymorphism in the AGT gene, which is the B6 dependent gene that causes primary hyperoxaluria. I hope we can do a genetic study like theirs in the autism population.Why was the autism and why have their GI issues and metabolic issues been ignored in primary hyperoxaluria?There was a complaint at the conference from a scientist who had done mouse studies that the "field" was ignoring the rest of the body and especially the blow that oxalate makes on the general metabolism, and the lack of treatments beyond liver transplants. I talked to him and gave him the good news that the Autism Oxalate Project at ARI HAS developed treatments that aide in the detoxification of oxalate. It is when detoxing oxalate that you see the worst symptoms, both in autism and in primary hyperoxaluria after they have a transplant.The detox process occurs in the body in earnest ONLY AFTER the sources of excess oxalate have been reduced...such as diet, and correcting vitamin deficiencies that lead to our cells making oxalate.The biggest issue on the vitamin front is pyridoxine (vitamin B6). Bernie Rimland studied B6 and magnesium therapy in autism for decades but he didn't know that these nutrients are critical to keep people from making oxalate metabolically. Enzymes that handle oxalate function in an organelle called the peroxisome, but until that enzyme binds B6, it cannot be imported into the peroxisome, so it cannot work properly. A scientist at the conference reported there is one mutation in primary hyperoxaluria where they found giving 400-600 mgs of pyridoxine a day pretty much solved the oxalate problem in that group! That's higher amount of B6 than anyone has gone for studying its effects in autism.So Rhonda, you asked a simple question, but the answer involves much more than Toni offered, though what she said was good. What Toni mentioned will help in reducing how much oxalate you absorb, but on our listserve I get into the particulars of which supplements have been documented as reducing the oxidative stress that comes from oxalate's effects on cells. There was lots in the literature to help us and it is incorporated into the recommendations I make on the listserve.Oxalate knocks out every important complex in the electron transport chain, at the same time as compromising glycolysis, gluconeogenesis, and the TCA cycle because of other enzymes it knocks out. Mitochondrial scientists do not know this literature as I learned while attending the United Mitochondrial Disease Foundation meeting this summer. Oxalate knocks out the enzyme that uses pyruvate to make citrate at the entrance into the Krebs cycle. People with high oxalate tend to be low citrate, and correcting the citrate will help reduce oxidative stress as the article below states! This is why the preferred form of calcium used is calcium citrate.If you want to know more, join our listserve where we discuss all this and have great helps for "newbies".I do not recommend people reducing oxalate without getting the benefit of the discussions on our listserve where you get the latest science as it happens. I cannot tell you how many people come to our listserve saying they've been LOD, but they were not getting the information they needed to get the results that they did get once they joined. This has happened because DAN! has not provided access for me to train ANY of the nutritionists/dieticians in Defeat Autism Now! that are trying to train others or advice patients on how to use the diet. Unfortunately, the ones who are giving out advice on LOD don't know what they don't know!Hum Exp Toxicol. 2009 Apr;28(4):245-51.Oxalate-mediated oxidant-antioxidant imbalance in erythrocytes: role of N-acetylcysteine.Bijarnia RK, Kaur T, Singla SK, Tandon C.Department of Biotechnology and Bioinformatics, Jaypee University of Information Technology, Waknaghat, India.AbstractThe present in-vivo study was to observe the effect of N-acetylcysteine (NAC) on oxalate-induced oxidative stress on rat erythrocytes. A total of 15 Wistar rats were divided into three groups. The control group received normal saline by single intraperitoneal injection. Hyperoxaluria was induced by single intraperitoneal (i.p.) dose of sodium oxalate (70 mg/kg body weight in 0.5 mL saline) to a second group. The third group was administered single i.p. dose of NAC according to 200 mg/kg body weight dissolved in 0.5 mL saline, half an hour after oxalate dose. NAC administration normalized antioxidant enzyme activities (superoxide dismutase and catalase) and reduced malondialdehyde content (indicator of lipid peroxidation) in hyperoxaluric rat's red blood cell (RBC) lysate. NAC administration also resulted in a significant improvement of thiol content in RBC lysate via increasing reduced glutathione content and maintaining its redox status. Oxalate-caused alteration of cholesterol/phospholipid ratio (determining membrane fluidity) was also rebalanced by NAC administration. Further, after NAC administration, electron microscopy showed improved cell morphology presenting its prophylactic properties. Above results indicate that NAC treatment is associated with an increase in plasma antioxidant capacity and a reduction in the susceptibility of erythrocyte membranes to oxidation. Thus, the study presents positive pharmacological implications of NAC against oxalate-mediated impairment of erythrocytes.PMID: 19734276Eur J Pharmacol. 2008 Jan 28;579(1-3):330-6.

Post Graduate Institute of Basic Medical Sciences, University of Madras, Taramani Campus, Chennai - 600 113, India.AbstractOxalate/calcium oxalate toxicity is mediated through generation of reactive oxygen species in a process that partly depends upon events that induce mitochondrial damage. Mitochondrial dysfunction is an important event favoring stone formation. The objective of the present study was to investigate whether mitochondria is a target for oxalate/calcium oxalate and the plausible role of naturally occurring glycosaminoglycans from edible seaweed, fucoidan in ameliorating mitochondrial damage. Male albino rats of Wistar strain were divided into four groups and treated as follows: Group I: vehicle treated control, Group II: hyperoxaluria was induced with 0.75% ethylene glycol in drinking water for 28 days, Group III: fucoidan from F. vesiculosus (5 mg/kg b.wt, s.c) from the 8th day of the experimental period, Group IV: ethylene glycol+fucoidan treated rats. The tricarboxylic acid (TCA) cycle enzymes like succinate dehydrogenase, isocitrate dehydrogenase, malate dehydrogenase and respiratory complex enzyme activities were assessed to evaluate mitochondrial function. Oxidative stress was assessed based on the activities of antioxidant enzymes, level of reactive oxygen species, lipid peroxidation and reduced glutathione. Mitochondrial swelling was also analyzed. Ultra structural changes in renal tissue were analyzed with electron microscope. Hyperoxaluria induced a decrease in the activities of TCA cycle enzymes and respiratory complex enzymes. The oxidative stress was evident by the decrease in antioxidant enzymes, glutathione and an increase in reactive species and lipid peroxidation in mitochondria. Mitochondrial damage was evident by increased mitochondrial swelling. Administration of fucoidan, decreased reactive oxygen species, lipid peroxidation (P<0.05), mitochondrial swelling and increased the activities of antioxidant enzymes and glutathione levels (P<0.05) and normalized the activities of mitochondrial TCA cycle and respiratory complex enzymes (P<0.05). From the present study, it can be concluded that mitochondrial damage is an essential event in hyperoxaluria, and fucoidan was able to effectively prevent it and thereby the renal damage in hyperoxaluria.PMID: 18001705J Urol. 2005 Feb;173(2):640-6.Citrate provides protection against oxalate and calcium oxalate crystal induced oxidative damage to renal epithelium.Byer K, Khan SR.Department of Pathology, Immunology and Laboratory Medicine, University of Florida, Gainesville, Florida 32610-0275, USA.AbstractPURPOSE: Oxalate and calcium oxalate (CaOx) crystals are injurious to renal epithelial cells. The injury is caused by the production of reactive oxygen species (ROS). Citrate is a well-known inhibitor of CaOx crystallization and as such it is one of the major therapeutic agents prescribed. Since citrate increases cellular reduced nicotinamide adenine dinucleotide phosphate and glutathione (GSH), we hypothesized that exogenously administered citrate should act as an antioxidant and protect cells from oxalate induced injury.MATERIALS AND METHODS: We exposed LLC-PK1 and MDCK cells to 500 microM/ml oxalate or 150 mug/cm calcium oxalate crystals for 30, 60 and 180 minutes with or without 3 mg/ml citrate in the medium. We determined cell viability by lactate dehydrogenase release and trypan blue exclusion, ROS involvement by changes in hydrogen peroxide and GSH, and lipid peroxidation by quantifying 8-isoprostane.RESULTS: The presence of citrate was associated with significant decrease in lactate dehydrogenase release (p <0.001) and staining with trypan blue (p <0.05). In addition, there was a significant increase in GSH (p <0.005) and a decrease in the production of hydrogen peroxide (p <0.05) and 8-isoprostane (p <0.0005) secretion into the culture medium when citrate was present in the medium.CONCLUSIONS: Citrate protects cells from oxalate and CaOx crystal induced injury by preventing lipid peroxidation through a decrease in ROS production. The results provide additional data for the beneficial role of citrate therapy for CaOx nephrolithiasis.PMID: 15643280 [>> What's is the best way to decrease oxalates and oxaditative stress > > Sent from my iPod> Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 20, 2010 Report Share Posted September 20, 2010 Could you give more details on the diet pls the information isGreat still need to research it all.... Thank youSent from my iPod Toni, Oxalate binds both lead and mercury and makes the body RETAIN them in a highly insoluble form. If your blood is high in oxalate BEFORE your exposure to these metals, then oxalate may compromise your ability to excrete these metals. The kidneys are where you have a high concentration of metals collecting and high concentrations of oxalate and they are where most chelators work. But if metals are bound to oxalate, they are not likely to be impairing enzymes, although the oxalate that bound them could be in the company of other oxalate that is free and impairing a long list of enzymes. Years ago, a DAN! doctor in Spain, Dr. Jesus Clavera started putting all her autism patients on reduced oxalate diets and found that the same chelation program she had been using on them for sometimes years was suddenly producing (after the diet) such higher elevations of metal excretions that she was worried about it and reduced the chelating agents in fear that the higher levels being excreted would cause harm. Because oxalate that is in BLOOD may change the way the kidney secretes fluids and adjusts pH, that means changes on any urine tests that are reported ratioed to creatinine can be misleading if no one notices whether and WHEN the analytes as a group shift down or up. You cannot tell if that shift has occurred in a Metals test done in isolation because there are no normal ranges for these toxins. This is why I studied 224 Great Plains organic acid tests collected over a period of about ten years. In that group, there was only one boy in which repeat tests did not show shifts in average urine concentration that were as great as three-fold over repeat tests. This shift, if it is as common in autism as it appears to be from this database, should effect the interpretation of all urine tests ratioed to creatinine including metals tests. I presented on this problem to the thinktank a couple of years ago. In other words, something shifts the ratio of creatinine to water and everything else in the urine, and a big suspect is oxalate that is being detoxified by the body, so moving from blood into the kidney for excretion. Let me give you an example. A parent sent me two organic acid tests done twelve hours apart on her son. When I asked her why the two tests were so close together, she told me the test was repeated after he was given a vitamin C IV and ended up in a metabolic crisis hours later that landed him in the Emergency Room. His oxalate level (vitamin C converts to oxalate in high amounts) had increased about twenty-fold in those hours, but his overall urine concentration of all the analytes on the test dropped three-fold in the twelve hours between the two tests. In other words, the analytes that shift in response to oxalate's enzyme inhibition in the mitochondrion were dramatically different, about a third way higher (as much as forty times higher), and a different third had dramatically shifted down in ways that could be understood by how oxalate impairs certain enzymes. After calculating the shift in the AVERAGE concentration, the other analytes were completely stable that wouldn't be affected by oxalate getting into the mitochondrion of cells. What was so shocking is that the effect of the higher oxalate in his blood would have made a metals test done at the same time look like the metals had fallen three fold! This is why I always recommend someone do an organic acid test at the same time as a metals test so that you can calculate that shift as I always do now on organic acid tests. Making this correction is how I've found a lot of children with fatty acid disorders and other things that the doctor didn't see from the "shifted" report. Tony, vitamin B6 is critical to the oxalate-protecting metabolism and also to the sulfur chemistry in helping us make sulfate and taurine. The lack of sulfate is what leads to PST problems, as they were studied by Dr. Rosemary Waring at the University of Birmingham in England many years ago. If anyone need more info on that, I suggest they read the archives on sulfurstories, a yahoogroup I set up after speaking on sulfur at DAN! conferences to the science and in another year to the regular sessions many years ago.

Guest guest Posted September 20, 2010 Report Share Posted September 20, 2010 , When I was at the United Mitochondrial Disease Foundation meeting this summer in Phoenix, it was clear that nobody there knew how oxalate could impair mitochondrial function, or how much help high dose biotin could be to reducing that inhibition. It occurred to me that those with inborn issues of mito function should be the first to know how to lessen the effect of mitochondrial toxins like oxalate. What I didm't know then and still don't know is if the mito issues predispose people to a leaky gut, which would make it easier for oxalate to become toxic, especially after infections or vaccines. That's all I could think about when I passed the children that were so weak their parents were pushing them around in wheelchairs. One poster presentation at the UMDF meeting showed how mito issues weakened the immune system in practically everyone with mitochondrial disease, and this seemed that it might be an explanation for why my own daughter and others like her had serious developmental regressions with vaccines, and why her immune system has been pitifully weak her whole life in such a way that immunologists turned a deaf ear because the only thing they knew to treat was allergies or immunoglobulin deficiencies! Also, my daughter had a serious vitamin D deficiency and half the literature suggested vitamin D would make her worse, and half better, but the experts on vitamin D knew nothing of the literature on how it affects the immune system, but I had read it. They wouldn't read it or think about what it meant regarding her lifelong immune deficiencies. It was with a lot of terror that I started her on vitamin D, not knowing if she would crash so badly that she wouldn't graduate from high school. I wish I had my money back from all the times I went to " the finest immunologists in town " , and had them accuse my daughter of faking her illnesses...like flu. She consequently distrusts doctors vehemently. It is hard for most people to realize that there is a BIG disconnect between the basic science literature and what doctors know or care to learn. I wish there were more people like me who are trying to break down the knowledge barriers by doing interdisciplinary study. Anyway, , I know you will persist and find the answers for your child, and if I can help in that journey, just let me know! One thing I don't know is if problems in pyridoxine binding other enzymes also leads to mistrafficking of them as it does with the oxalate-related enzyme AGT. Sometimes it is very difficult to find studies that are overt about where enzymes are made, assembled with co-factors and how they move to where they work. > > > > > > What's is the best way to decrease oxalates and oxaditative stress > > > > > > Sent from my iPod > > > > Quote Link to comment Share on other sites More sharing options...

Guest guest Posted September 20, 2010 Report Share Posted September 20, 2010 , This child is teaching US by her own determination whether she is now " well " ! I don't think I would have advised her mother to stop either the diet or the supplements, but this child was maturing emotionally so fast that she was becoming a little teenager and wanting to be her own person. So, for the sake of peace in their home, and the child's self-esteem, her mother quit insisting on the supplements and let her manage her own body. We were both shocked that this child reached that point of emotional maturity so soon, but once it happened, there was no turning back! I think at camp she probably did not totally maintain the diet, but her mother still cooks low oxalate at home. The mom needs to be low oxalate, too, as is true with a lot of moms as they discover on their own! This mother had serious dumping herself that at one point was serious enough to get her in the hospital because it induced a fever and respiratory issues. (We see that level of serious dump in some adults who are on the diet and have had more years to accumulate oxalate in tissues. This is NOT autism specific.) Soon after that, I think, the mom developed a kidney stone made from calcium oxalate. This brings up the issue that a lot of children may get loaded with oxalate in utero when the mom has oxalate issues. I think that was true of me and my daughter who was pretty fine the first week after birth, but developed sucking problems the second week and had to be fed with a syringe until after she was two months old and had enough strength to suck. At the same time, I developed a weakness that made it where I could not stand up long enough to get her diaper changed. This lasted about two months, and during that time I was nursing her. Oxalate does get in breastmilk. My daughter's first vaccines wiped her out, and she got where she didn't respond to my shaking a toy in front of her face and she lost skills she had before. That was the only time she seemed maybe autistic-like, but her issues became developmental delay, gravitational insecurity and gross motor delay with sensory integration problems...not autism. In retrospect, we think she had fibromyalgia even as an infant. No, chelation did NOT help this other child. It was when this child was chelated with DMSA that I met the mom when she wrote a panicked email on some listserves that said using DMSA had suddenly caused her child to go almost totally blind. She could not recognize her mother standing right next to her. The mother thought this happened from redistributing mercury as that was the going paradigm. I learned that this child had congenital nystagmus and I already knew some nystagmus is caused by thiamine deficiency. It was reasonable that the DMSA oxidized the only thiamine that this child could get across the cell membrane due to a likely thiamine transporter defect, so I suggested that she give the child TTFD which can cross the cell membrane when the transporter doesn't work. This is what they did, and the child pretty much immediately got her vision back. Her father, who also has congenital nystagmus started taking TTFD and foumd it made him see better, and get less fatigued when reading. This is the one supplement I hope this child WILL take all her life. That child's having her vision restored is why WHEN I introduced the oxalate issue to the autism community almost six years ago, this mom was one of the first to give it a whirl, because she respected my knowledge and ability to get the significant and practical facts out of the medical literature and out of case histories. Unlike some of our early listmates who quit or got discouraged when they started to dump, or when others started to bash the diet out of loyalty to SCD or chocolate or milk substitutes, this family endured the dumping cycles, and has the loss of this child's autism diagnosis to thank for their persistence! Some issues just take a lot of context and a lot of knowledge of biological mechanisms to resolve. The knowledge I have has taken me fifteen years of independent study to acquire through reading now probably a thousand scientific papers on various topics, and analyzing labwork on hundreds of children and adults to say nothing of being part of the DAN! thinktank most of those years. One of the strengths of the oxalate theory (ie, that oxalate is a significant part of autism almost always) is that it ties together an explanation for why so many treatments may have worked that were thought to have worked by other mechanisms. A success in treatment does not authenticate the theory behind the treatment, but it does say that there is a mechanism involved with treatment that is legitimate...maybe not the mechanism that everyone is focused upon. Every child that changes significantly or who has a disaster with a therapy holds the key to understanding how others may have a way to succeed, and this child has been a great example of that. Thiamine deficiency also impairs the enzyme that keeps meat from being metabolized in a way that generates oxalate in omnivores (like humans). DMSA was the WRONG therapy for this child. Any other chelator would probably generate the same disaster. Mercury was NOT her issue, but her experience and failure using a typical therapy taught us so much! Never, never think that a failure in a therapy is a blind road. It can be the key to really understanding what is going on! > > Thank you , > Does this child still need the diet, even if she is off of the supplements? And if so, what then gets to the root of the problem, chelation? And my question pertains to children who have high oxalates, but no other markers suggesting it's a genetic disorder. > > > Quote Link to comment Share on other sites More sharing options...

I learned that this child had congenital nystagmus and I already knew some nystagmus is caused by thiamine deficiency. It was reasonable that the DMSA oxidized the only thiamine that this child could get across the cell membrane due to a likely thiamine transporter defect, so I suggested that she give the child TTFD which can cross the cell membrane when the transporter doesn't work. This is what they did, and the child pretty much immediately got her vision back. Her father, who also has congenital nystagmus started taking TTFD and foumd it made him see better, and get less fatigued when reading. This is the one supplement I hope this child WILL take all her life. That child's having her vision restored is why WHEN I introduced the oxalate issue to the autism community almost six years ago, this mom was one of the first to give it a whirl, because she respected my knowledge and ability to get the significant and practical facts out of the medical literature and out of case histories. Unlike some of our early listmates who quit or got discouraged when they started to dump, or when others started to bash the diet out of loyalty to SCD or chocolate or milk substitutes, this family endured the dumping cycles, and has the loss of this child's autism diagnosis to thank for their persistence! Some issues just take a lot of context and a lot of knowledge of biological mechanisms to resolve. The knowledge I have has taken me fifteen years of independent study to acquire through reading now probably a thousand scientific papers on various topics, and analyzing labwork on hundreds of children and adults to say nothing of being part of the DAN! thinktank most of those years. One of the strengths of the oxalate theory (ie, that oxalate is a significant part of autism almost always) is that it ties together an explanation for why so many treatments may have worked that were thought to have worked by other mechanisms. A success in treatment does not authenticate the theory behind the treatment, but it does say that there is a mechanism involved with treatment that is legitimate...maybe not the mechanism that everyone is focused upon. Every child that changes significantly or who has a disaster with a therapy holds the key to understanding how others may have a way to succeed, and this child has been a great example of that. Thiamine deficiency also impairs the enzyme that keeps meat from being metabolized in a way that generates oxalate in omnivores (like humans). DMSA was the WRONG therapy for this child. Any other chelator would probably generate the same disaster. Mercury was NOT her issue, but her experience and failure using a typical therapy taught us so much! Never, never think that a failure in a therapy is a blind road. It can be the key to really understanding what is going on! > > Thank you , > Does this child still need the diet, even if she is off of the supplements? And if so, what then gets to the root of the problem, chelation? And my question pertains to children who have high oxalates, but no other markers suggesting it's a genetic disorder. > > > Quote Link to comment Share on other sites More sharing options...

Guest guest Posted September 21, 2010 Report Share Posted September 21, 2010 How do I join,what you are calling a" list serve"? I know my son has this polimorph gene and I would like to see your great imfo.as it happens. Thanks,Tammy F. From K.S. Rhonda, Oxalates themselves cause an enormous amount of oxidative stress and lipid peroxidation, depleting glutathione, and shutting down the energy metabolism in cells where oxalate gets into the mitochondrion. For more info on this, see the studies I've put below on oxalate's effects on red blood cells and the mitochondrion and the kidney. I've recently gone to the primary hyperoxaluria conference in NYC where they discussed the genetic condition where an enzyme defect makes their liver churn out high levels of excess oxalate and there, I found autism. The field is RUN by kidney doctors who only start treating these patients after they get in kidney failure, but they have failed to recognize other things that happen in these patients earlier. Included there would be horrible GI problems and GI pain, bone pain, and according to one doctor I talked to from Canada, a list of the same conditions we see getting better on the low oxalate diet outside autism, like fibromyalgia, interstitial cystitis, and vulvodynia. They had a mixer where the people at the patient conference could mingle with the scientists who attended the scientific conference, so in talking to the families and to the only person who has done a clinical study on a large group of these patients, I learned about undocumented autism that seems it could be common in this genetic disease. (There are only about 500 cases of primary hyperoxaluria that have been identified in the whole world. Because of their gene defect oxalate levels in blood and urine and tissues soar.) The first family I met had a son with primary oxaluria who had OCD and Aspergers. The next family with a toddler had an uncle with autism and the mother had hydrocephalus. That was striking to me because one of the most dramatic improvements on the diet has been a child with autism who had failed to develop past infancy and had hydrocephalus and was given a shunt, but his development arrested there. He only began "infant" development at age five once he was on the diet. A fifteen or so year old boy sat by himself at my table and never looked up as I got up, sat down, got up over and over again, but he was immersed in a game toy he was playing with during the whole hour and a half of the party. That seemed "spectrumish" to me, although I didn't talk to him since I never got eye contact. Later, I had lunch with a scientist who is developing the orphan drug probiotic oxalobacter formigenes. She has been doing Phase II and III drug trials on this product which is the only treatment study that has ever been done in primary hyperoxaluria aimed at reducing oxalate. When I told her all the families I had met that seemed to have autism in the family, she said, "Oh yes. They are not normal." (She's a microbiologist...so you wouldn't expect her to be able to diagnose autism, but what she said told me that the kidney doctors also had been ignoring this issue, just like doctors and psychiatrists for so many years ignored the GI issues in autism.) Rhonda, our listserve has had people with other genetic diseases comorbid with autism that have genetic reasons for gut permeability and their autism symptoms have improved on the diet just like the "regular" autism kids. There may be polymorphisms for oxalate issues that increase risks of not being able to "handle" oxalate. A study in France found that most patients given a drug that contains large amounts of oxalate developed neurotoxicity, but the level of neurotoxicity appeared to be determined by the presence or absence of a polymorphism in the AGT gene, which is the B6 dependent gene that causes primary hyperoxaluria. I hope we can do a genetic study like theirs in the autism population. Why was the autism and why have their GI issues and metabolic issues been ignored in primary hyperoxaluria? There was a complaint at the conference from a scientist who had done mouse studies that the "field" was ignoring the rest of the body and especially the blow that oxalate makes on the general metabolism, and the lack of treatments beyond liver transplants. I talked to him and gave him the good news that the Autism Oxalate Project at ARI HAS developed treatments that aide in the detoxification of oxalate. It is when detoxing oxalate that you see the worst symptoms, both in autism and in primary hyperoxaluria after they have a transplant. The detox process occurs in the body in earnest ONLY AFTER the sources of excess oxalate have been reduced...such as diet, and correcting vitamin deficiencies that lead to our cells making oxalate. The biggest issue on the vitamin front is pyridoxine (vitamin B6). Bernie Rimland studied B6 and magnesium therapy in autism for decades but he didn't know that these nutrients are critical to keep people from making oxalate metabolically. Enzymes that handle oxalate function in an organelle called the peroxisome, but until that enzyme binds B6, it cannot be imported into the peroxisome, so it cannot work properly. A scientist at the conference reported there is one mutation in primary hyperoxaluria where they found giving 400-600 mgs of pyridoxine a day pretty much solved the oxalate problem in that group! That's higher amount of B6 than anyone has gone for studying its effects in autism. So Rhonda, you asked a simple question, but the answer involves much more than Toni offered, though what she said was good. What Toni mentioned will help in reducing how much oxalate you absorb, but on our listserve I get into the particulars of which supplements have been documented as reducing the oxidative stress that comes from oxalate's effects on cells. There was lots in the literature to help us and it is incorporated into the recommendations I make on the listserve. Oxalate knocks out every important complex in the electron transport chain, at the same time as compromising glycolysis, gluconeogenesis, and the TCA cycle because of other enzymes it knocks out. Mitochondrial scientists do not know this literature as I learned while attending the United Mitochondrial Disease Foundation meeting this summer. Oxalate knocks out the enzyme that uses pyruvate to make citrate at the entrance into the Krebs cycle. People with high oxalate tend to be low citrate, and correcting the citrate will help reduce oxidative stress as the article below states! This is why the preferred form of calcium used is calcium citrate. If you want to know more, join our listserve where we discuss all this and have great helps for "newbies". I do not recommend people reducing oxalate without getting the benefit of the discussions on our listserve where you get the latest science as it happens. I cannot tell you how many people come to our listserve saying they've been LOD, but they were not getting the information they needed to get the results that they did get once they joined. This has happened because DAN! has not provided access for me to train ANY of the nutritionists/dieticians in Defeat Autism Now! that are trying to train others or advice patients on how to use the diet. Unfortunately, the ones who are giving out advice on LOD don't know what they don't know! Hum Exp Toxicol. 2009 Apr;28(4):245-51. Oxalate-mediated oxidant-antioxidant imbalance in erythrocytes: role of N-acetylcysteine. Bijarnia RK, Kaur T, Singla SK, Tandon C. Department of Biotechnology and Bioinformatics, Jaypee University of Information Technology, Waknaghat, India. Abstract The present in-vivo study was to observe the effect of N-acetylcysteine (NAC) on oxalate-induced oxidative stress on rat erythrocytes. A total of 15 Wistar rats were divided into three groups. The control group received normal saline by single intraperitoneal injection. Hyperoxaluria was induced by single intraperitoneal (i.p.) dose of sodium oxalate (70 mg/kg body weight in 0.5 mL saline) to a second group. The third group was administered single i.p. dose of NAC according to 200 mg/kg body weight dissolved in 0.5 mL saline, half an hour after oxalate dose. NAC administration normalized antioxidant enzyme activities (superoxide dismutase and catalase) and reduced malondialdehyde content (indicator of lipid peroxidation) in hyperoxaluric rat's red blood cell (RBC) lysate. NAC administration also resulted in a significant improvement of thiol content in RBC lysate via increasing reduced glutathione content and maintaining its redox status. Oxalate-caused alteration of cholesterol/phospholipid ratio (determining membrane fluidity) was also rebalanced by NAC administration. Further, after NAC administration, electron microscopy showed improved cell morphology presenting its prophylactic properties. Above results indicate that NAC treatment is associated with an increase in plasma antioxidant capacity and a reduction in the susceptibility of erythrocyte membranes to oxidation. Thus, the study presents positive pharmacological implications of NAC against oxalate-mediated impairment of erythrocytes. PMID: 19734276 Eur J Pharmacol. 2008 Jan 28;579(1-3):330-6.

Department of Medical Biochemistry, Dr. ALM. Post Graduate Institute of Basic Medical Sciences, University of Madras, Taramani Campus, Chennai - 600 113, India. Abstract Oxalate/calcium oxalate toxicity is mediated through generation of reactive oxygen species in a process that partly depends upon events that induce mitochondrial damage. Mitochondrial dysfunction is an important event favoring stone formation. The objective of the present study was to investigate whether mitochondria is a target for oxalate/calcium oxalate and the plausible role of naturally occurring glycosaminoglycans from edible seaweed, fucoidan in ameliorating mitochondrial damage. Male albino rats of Wistar strain were divided into four groups and treated as follows: Group I: vehicle treated control, Group II: hyperoxaluria was induced with 0.75% ethylene glycol in drinking water for 28 days, Group III: fucoidan from F. vesiculosus (5 mg/kg b.wt, s.c) from the 8th day of the experimental period, Group IV: ethylene glycol+fucoidan treated rats. The tricarboxylic acid (TCA) cycle enzymes like succinate dehydrogenase, isocitrate dehydrogenase, malate dehydrogenase and respiratory complex enzyme activities were assessed to evaluate mitochondrial function. Oxidative stress was assessed based on the activities of antioxidant enzymes, level of reactive oxygen species, lipid peroxidation and reduced glutathione. Mitochondrial swelling was also analyzed. Ultra structural changes in renal tissue were analyzed with electron microscope. Hyperoxaluria induced a decrease in the activities of TCA cycle enzymes and respiratory complex enzymes. The oxidative stress was evident by the decrease in antioxidant enzymes, glutathione and an increase in reactive species and lipid peroxidation in mitochondria. Mitochondrial damage was evident by increased mitochondrial swelling. Administration of fucoidan, decreased reactive oxygen species, lipid peroxidation (P<0.05), mitochondrial swelling and increased the activities of antioxidant enzymes and glutathione levels (P<0.05) and normalized the activities of mitochondrial TCA cycle and respiratory complex enzymes (P<0.05). From the present study, it can be concluded that mitochondrial damage is an essential event in hyperoxaluria, and fucoidan was able to effectively prevent it and thereby the renal damage in hyperoxaluria.

Department of Pathology, Immunology and Laboratory Medicine, University of Florida, Gainesville, Florida 32610-0275, USA. Abstract PURPOSE: Oxalate and calcium oxalate (CaOx) crystals are injurious to renal epithelial cells. The injury is caused by the production of reactive oxygen species (ROS). Citrate is a well-known inhibitor of CaOx crystallization and as such it is one of the major therapeutic agents prescribed. Since citrate increases cellular reduced nicotinamide adenine dinucleotide phosphate and glutathione (GSH), we hypothesized that exogenously administered citrate should act as an antioxidant and protect cells from oxalate induced injury. MATERIALS AND METHODS: We exposed LLC-PK1 and MDCK cells to 500 microM/ml oxalate or 150 mug/cm calcium oxalate crystals for 30, 60 and 180 minutes with or without 3 mg/ml citrate in the medium. We determined cell viability by lactate dehydrogenase release and trypan blue exclusion, ROS involvement by changes in hydrogen peroxide and GSH, and lipid peroxidation by quantifying 8-isoprostane. RESULTS: The presence of citrate was associated with significant decrease in lactate dehydrogenase release (p <0.001) and staining with trypan blue (p <0.05). In addition, there was a significant increase in GSH (p <0.005) and a decrease in the production of hydrogen peroxide (p <0.05) and 8-isoprostane (p <0.0005) secretion into the culture medium when citrate was present in the medium. CONCLUSIONS: Citrate protects cells from oxalate and CaOx crystal induced injury by preventing lipid peroxidation through a decrease in ROS production. The results provide additional data for the beneficial role of citrate therapy for CaOx nephrolithiasis.

Guest guest Posted September 21, 2010 Report Share Posted September 21, 2010 thank you , Alison M Re: Oxalates ,When I was at the United Mitochondrial Disease Foundation meeting this summer in Phoenix, it was clear that nobody there knew how oxalate could impair mitochondrial function, or how much help high dose biotin could be to reducing that inhibition. It occurred to me that those with inborn issues of mito function should be the first to know how to lessen the effect of mitochondrial toxins like oxalate.What I didm't know then and still don't know is if the mito issues predispose people to a leaky gut, which would make it easier for oxalate to become toxic, especially after infections or vaccines. That's all I could think about when I passed the children that were so weak their parents were pushing them around in wheelchairs.One poster presentation at the UMDF meeting showed how mito issues weakened the immune system in practically everyone with mitochondrial disease, and this seemed that it might be an explanation for why my own daughter and others like her had serious developmental regressions with vaccines, and why her immune system has been pitifully weak her whole life in such a way that immunologists turned a deaf ear because the only thing they knew to treat was allergies or immunoglobulin deficiencies! Also, my daughter had a serious vitamin D deficiency and half the literature suggested vitamin D would make her worse, and half better, but the experts on vitamin D knew nothing of the literature on how it affects the immune system, but I had read it.

Guest guest Posted September 21, 2010 Report Share Posted September 21, 2010 thank you , Alison M Re: Oxalates ,When I was at the United Mitochondrial Disease Foundation meeting this summer in Phoenix, it was clear that nobody there knew how oxalate could impair mitochondrial function, or how much help high dose biotin could be to reducing that inhibition. It occurred to me that those with inborn issues of mito function should be the first to know how to lessen the effect of mitochondrial toxins like oxalate.What I didm't know then and still don't know is if the mito issues predispose people to a leaky gut, which would make it easier for oxalate to become toxic, especially after infections or vaccines. That's all I could think about when I passed the children that were so weak their parents were pushing them around in wheelchairs.One poster presentation at the UMDF meeting showed how mito issues weakened the immune system in practically everyone with mitochondrial disease, and this seemed that it might be an explanation for why my own daughter and others like her had serious developmental regressions with vaccines, and why her immune system has been pitifully weak her whole life in such a way that immunologists turned a deaf ear because the only thing they knew to treat was allergies or immunoglobulin deficiencies! Also, my daughter had a serious vitamin D deficiency and half the literature suggested vitamin D would make her worse, and half better, but the experts on vitamin D knew nothing of the literature on how it affects the immune system, but I had read it. They wouldn't read it or think about what it meant regarding her lifelong immune deficiencies. It was with a lot of terror that I started her on vitamin D, not knowing if she would crash so badly that she wouldn't graduate from high school.I wish I had my money back from all the times I went to "the finest immunologists in town", and had them accuse my daughter of faking her illnesses...like flu.
