Guest guest Posted January 16, 2008 Report Share Posted January 16, 2008 forwarding this from another list - are there any people on this list with adult ASD kids? I was wondering if any tended to drank wine (or other alcohol), and if noticed any changes in 'autism'? .....I was very intrigued by something posted on another board. In this link a woman is saying her child (adult Aspie) seems more typical after drinking alcohol and that he doesn't seem drunk at all. If this was across the board with all ASD kids/adults or even very common it might point to something in that is worth looking into. Indeed one comment left on board confirmed the effects in another ASD individual. http://youtube.com/watch?v=MWXLiTcq4y0 I have had a quick look through literature and it turns up alcohol, esp. some types of drinks, decrease inflammatory responses. Sometimes dramatically. It is well know that chronic long-term consumption/intoxification messes up the immune system… I have copied some most interesting abstracts here, wonder if anyone would have any thoughts on this, or maybe some other mechanisms that could be at work… Natasa Atherosclerosis. 2007 Jun;192(2):335-41.

Ethanol beverages containing polyphenols decrease nuclear factor kappa-B activation in mononuclear cells and circulating MCP-1 concentrations in healthy volunteers during a fat-enriched diet. Blanco-Colio LM.. AIMS: Different epidemiological studies have demonstrated that some ethanol containing beverages intake could be associated with a reduction of cardiovascular mortality, effect attributed in part to its antioxidant properties. Nuclear factor-kappa B (NF-kappaB) is a redox sensitive transcription factor implicated in the pathogenesis of atherosclerosis. We have examined the effect of four different ethanol containing beverages on the activation of NF-kappaB in peripheral blood mononuclear cells (PBMC) and circulating concentrations of monocyte chemoattractant protein-1 (MCP-1) in healthy volunteers receiving a fat-enriched diet. METHODS AND RESULTS: Sixteen volunteers received 16 g/m(2) of ethanol in form of red wine, spirits (vodka, rum, and brandy) or no ethanol intake along with a fat-enriched diet during 5 days and all of them took all alcohols at different periods. NF-kappaB activation (electrophoretic mobility shift assay) and circulating MCP-1 levels (ELISA) were examined in blood samples taken before and after 5 days of ethanol intake. Subjects receiving a fat-enriched diet had increased NF-kappaB activation in PBMC at day 5. Furthermore, MCP-1 levels were increased in plasma at day 5. Red wine intake and some ethanol beverages containing polyphenols (brandy and rum) prevented NF-kappaB activation and decreased MCP-1 release. CONCLUSION: Consumption of moderate amounts of alcoholic drinks containing polyphenols decreases NF-kappaB activation in PBMCs and MCP-1 plasma levels during a fat-enriched diet. Our results provide additional evidence of the anti-inflammatory effects of some ethanol containing beverages, further supporting the idea that its moderate consumption may help to reduce overall cardiovascular mortality.

Effects of systemic and local CXC chemokine administration on the ethanol-induced suppression of pulmonary neutrophil recruitment. Quinton LJ, S, Zhang P, Happel KI, Gamble L, Bagby GJ. Department of Physiology, Louisiana State University Health Sciences Center, New Orleans, Louisiana 70112, USA. BACKGROUND: Acute alcohol intoxication impairs the neutrophil response to intrapulmonary infection, resulting in impaired host defense and increased patient morbidity and mortality. We recently showed that intratracheal (IT) chemokine administration promotes pulmonary neutrophil migration in rats and that this process is enhanced by systemic administration of the Glu-Leu-Arg (ELR+) and CXC chemokine cytokine-induced neutrophil chemoattractant (CINC). Here we hypothesized that exogenous chemokine administration would mitigate the suppressive effect of alcohol on neutrophil recruitment into the lung. METHODS: Macrophage inflammatory protein-2 (MIP-2), a rat ELR+ CXC chemokine, or live Klebsiella pneumoniae (K. pneumoniae) was administered it to induce alveolar neutrophil migration in the absence or presence of acute ethanol intoxication. Depending on the experimental protocol, rats received either intravenous (IV) CINC or IT chemokines (CINC and MIP-2) 20 min after it MIP-2 or K. pneumoniae. Rats were euthanized 90 min or four hr after the first IT injection for sample collection. RESULTS: Neutrophil counts were significantly elevated in bronchoalveolar lavage fluid (BALF) of rats receiving IT MIP-2 compared with vehicle-treated rats, and this response was significantly decreased in animals pretreated with ethanol. CINC IV enhanced the neutrophil response to IT MIP-2 in both the absence and presence of acute ethanol intoxication. In rats challenged with K. pneumoniae, ethanol pretreatment significantly reduced BALF levels of CINC and MIP-2, suppressed alveolar neutrophil recruitment, and decreased whole-lung myeloperoxidase activity. CINC IV did not alter BALF neutrophil counts in the absence or presence of ethanol administration 4 hr after IT K. pneumoniae. Alternatively, IT chemokine instillation partially restored BALF neutrophil recruitment but not whole-lung myeloperoxidase activity in ethanol-treated rats. CONCLUSIONS: Ethanol significantly inhibits the pulmonary inflammatory responses to both MIP-2 and K. pneumoniae. Exogenous chemokine administration may be a useful means to enhance host defenses in the ethanol-intoxicated host, although the results of this study also indicate that ethanol intoxication can impair neutrophil recruitment, independent of its effects on local chemotactic gradients.

Ethanol inhibits monocyte chemotactic protein-1 expression in interleukin-1{beta}-activated human endothelial cells. Cullen JP, Sayeed S, Jin Y, Theodorakis NG, Sitzmann JV, Cahill PA, Redmond EM. Department of Surgery, University of Rochester Medical Center, Rochester, New York 14642, USA. The aim of this study was to determine the effect of ethanol (EtOH) on endothelial monocyte chemotactic protein-1 (MCP-1) expression. IL-1beta increased the production of MCP-1 by human umbilical vein endothelial cells from undetectable levels to approximately 900 pg/ml at 24 h. EtOH dose-dependently inhibited IL-1beta-stimulated MCP-1 secretion as determined by ELISA: 25 +/- 1%, 35 +/- 7%, and 65 +/- 5% inhibition for 1, 10, and 100 mM EtOH, respectively, concomitant with inhibition of monocyte adhesion to activated endothelial cells. Similarly, EtOH dose-dependently inhibited IL-1beta-stimulated MCP-1 mRNA expression. Experiments with actinomycin D demonstrated that EtOH decreased the stability of MCP-1 mRNA. In addition, EtOH significantly reduced NF-kappaB and AP-1 binding activity induced by IL-1beta and inhibited MCP-1 gene transcription. Binding of (125)I-labeled MCP-1 to its receptor (CCR2) on THP-1 human monocytic cells was not affected by EtOH treatment. Modulation of the expression of MCP-1 represents a mechanism whereby EtOH could inhibit atherogenesis by blocking the crucial early step of monocyte adhesion and subsequent recruitment to the subendothelial space. These actions of EtOH may underlie, in part, its cardiovascular protective effects in vivo. Publication Types: PMID: 15908470 [PubMed - indexed for MEDLINE] 4: J Immunol. 2004 Nov 15;173(10):6376-83. Ethanol blocks leukocyte recruitment and endothelial cell activation in vivo and in vitro. Saeed RW, Varma S, Peng T, Tracey KJ, Sherry B, Metz CN. Laboratories of Medical Biochemistry, North Shore-Long Island Jewish Research Institute, 350 Community Drive, Manhasset, NY 11030, USA. Immune system impairment and increased susceptibility to infection among alcohol abusers is a significant but not well-understood problem. We hypothesized that acute ethanol administration would inhibit leukocyte recruitment and endothelial cell activation during inflammation and infection. Using LPS and carrageenan air pouch models in mice, we found that physiological concentrations of ethanol (1-5 g/kg) significantly blocked leukocyte recruitment (50-90%). Because endothelial cell activation and immune cell-endothelial cell interactions are critical regulators of leukocyte recruitment, we analyzed the effect of acute ethanol exposure on endothelial cell activation in vivo using the localized Shwartzman reaction model. In this model, ethanol markedly suppressed leukocyte accumulation and endothelial cell adhesion molecule expression in a dose-dependent manner. Finally, we examined the direct effects of ethanol on endothelial cell activation and leukocyte-endothelial cell interactions in vitro. Ethanol, at concentrations within the range found in human blood after acute exposure and below the levels that induce cytotoxicity (0.1-0.5%), did not induce endothelial cell activation, but significantly inhibited TNF-mediated endothelial cell activation, as measured by adhesion molecule (E-selectin, ICAM-1, VCAM-1) expression and chemokine (IL-8, MCP-1, RANTES) production and leukocyte adhesion in vitro. Studies exploring the potential mechanism by which ethanol suppresses endothelial cell activation revealed that ethanol blocked NF-kappaB nuclear entry in an IkappaBalpha-dependent manner. These findings support the hypothesis that acute ethanol overexposure may increase the risk of infection and inhibit the host inflammatory response, in part, by blocking endothelial cell activation and subsequent immune cell-endothelial cell interactions required for efficient immune cell recruitment.

Suppression of innate immunity by acute ethanol administration: a global perspective and a new mechanism beginning with inhibition of signaling through TLR3. Pruett SB, Schwab C, Zheng Q, Fan R. Department of Cellular Biology and Anatomy, Louisiana State University Health Sciences Center, Shreveport, LA 71130, USA. spruet@... Excessive consumption of ethanol (EtOH) suppresses innate immunity, but the mechanisms have not been fully delineated. The present study was conducted to determine whether EtOH suppresses TLR signaling in vivo in mice and to characterize the downstream effects of such suppression. Degradation of IL-1R-associated kinase 1 induced by a TLR3 ligand in peritoneal cells ( approximately 90% macrophages) was suppressed by EtOH. Phosphorylation of p38 kinase in peritoneal macrophages (F4/80(+)) was suppressed, as was nuclear translocation of p-c-Jun and p65 in peritoneal cells. EtOH decreased IL-6 and IL-12 (p40), but did not significantly affect IL-10 in peritoneal lavage fluid or in lysates of peritoneal cells. Changes in cytokine mRNAs (by RNase protection assay) in macrophages isolated by cell sorting or using Ficoll were generally consistent with changes in protein levels in cell lysates and peritoneal lavage fluid. Thus, suppression of TLR signaling and cytokine mRNA occurred in the same cells, and this suppression generally corresponded to changes in i.p. and intracellular cytokine concentrations. DNA microarray analysis revealed the suppression of an IFN-related amplification loop in peritoneal macrophages, associated with decreased expression of numerous innate immune effector genes (including cytokines and a chemokine also suppressed at the protein level). These results indicate that EtOH suppresses innate immunity at least in part by suppressing TLR3 signaling, suppressing an IFN-related amplification loop, and suppressing the induction of a wide range of innate effector molecules in addition to proinflammatory cytokines and chemokines.

Different effects of red wine and gin consumption on inflammatory biomarkers of atherosclerosis: a prospective randomized crossover trial. Effects of wine on inflammatory markers. Estruch R, Sacanella E, Badia E, Antúnez E, Nicolás JM, Fernández-Solá J, Rotilio D, de Gaetano G, Rubin E, Urbano-Márquez A. Department of Internal Medicine, Hospital Clinic, Institut d'Investigacions Biomèdiques August Pi i Sunyer (IDIBAPS), University of Barcelona, Barcelona, Spain. BACKGROUND: No intervention studies have explored the anti-inflammatory effects of different alcoholic beverages on markers of atherosclerosis. We embarked on a randomized, crossover, single-blinded trial to evaluate the effects of wine and gin on inflammatory biomarkers of atherosclerosis. METHODS AND RESULTS: Forty healthy men (mean age, 37.6 years) consumed 30 g ethanol per day as either wine or gin for 28 days. Before and after each intervention, we measured the expression of lymphocyte function-associated antigen 1 (LFA-1), Mac-1, very late activation antigen 4 (VLA-4), and monocyte chemoattractant protein (MCP-1) in monocytes, as well as the soluble vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), interleukin-1alpha (IL-1alpha), C-reactive protein (hs-CRP) and fibrinogen. After either gin or wine consumption, plasma fibrinogen decreased by 5 and 9%, respectively, and cytokine IL-1alpha by 23 and 21%. The expression of LFA-1 (-27%), Mac-1 (-27%), VLA-4 (-32%) and MCP-1 (-46%) decreased significantly after wine, but not after gin. Wine reduced the serum concentrations of hs-CRP (-21%), VCAM-1 (-17%) and ICAM-1 (-9%). CONCLUSIONS: Both wine and gin showed anti-inflammatory effects by reducing plasma fibrinogen and IL-1alpha levels. However, wine had the additional effect of decreasing hs-CRP, as well as monocyte and endothelial adhesion molecules.

Alcohol modulates circulating levels of interleukin-6 and monocyte chemoattractant protein-1 in chronic pancreatitis. Pedersen N, Larsen S, Seidelin JB, Nielsen OH Dept. of Medicine M, Division of Gastroenterology, Glostrup Hospital, University of Copenhagen, Denmark. BACKGROUND: Cytokines are markers of acute pancreatic inflammation and essential for distant organ injury, but they also stimulate pancreatic fibrogenesis and are thus involved in the progression from acute pancreatitis to chronic pancreatic injury and fibrosis. The aim of this study was to evaluate the circulating levels of IL-6, MCP-1, TGF-beta1, IGF-1 and IGFBP-3 in patients with alcoholic chronic pancreatitis (CP). METHODS: Twelve male patients with severe CP and 11 matched controls ingested 40 g alcohol. Plasma cytokine concentrations were measured for 24 h and assessed by sandwich ELISA techniques. RESULTS: IL-6 was higher in CP at fasting and 1, 4 and 24 h after alcohol intake (P < 0.04), and a significantly greater rise was found at 1 h compared to pre-stimulatory conditions and controls (P < 0.01). MCP-1 plasma levels in CP were significantly decreased at I h (P < 0.01) and 4 h (P < 0.001) compared to pre-stimulatory levels and controls, and a variance analysis showed significantly (P < 0.001) lower post-stimulatory levels at 1 h and 4 h both in CP and in controls. Alcohol consumption (40 g), however, did not influence plasma levels of TGF-1beta, IGF-I or IGFBP-3 in either of the two groups at the time frame applied. CONCLUSIONS: Acute alcohol intake induces a rise in the plasma levels of IL-6 in CP as compared to controls. The low circulating concentrations of MCP-1 1 and 4 h following alcohol consumption might possibly reflect that this mediator acts locally via autocrine mechanisms.

Alcohol-induced suppression of lung chemokine production and the host defense response to Streptococcus pneumoniae. Boé DM, S, Zhang P, Quinton L, Bagby GJ. Department of Physiology, Alcohol Research Center, Louisianna State University Health Sciences Center, New Orleans 70112, USA. BACKGROUND: Acute alcohol intoxication impairs neutrophil migration in response to intrapulmonary infection with Streptococcus pneumoniae, the most common bacterial cause of pneumonia. Many of the same host defense functions that are impaired in the alcohol-intoxicated host are mechanistically associated with chemokines, a group of proinflammatory molecules that enhance neutrophil adhesion and direct neutrophil migration to sites of inflammation. The purpose of this study was to determine whether alcohol-induced chemokine suppression is responsible for impaired neutrophil recruitment into the lung during infection of the alcohol-intoxicated host. METHODS: S. pneumoniae was administered (107 colony-forming units) intratracheally 30 min after intraperitoneal injection of 20% alcohol (5.5 g/kg) or saline. Four hours after bacterial challenge, bronchoalveolar lavage fluid (BALF) was collected, and the ability of BALF to induce neutrophil chemotaxis and adhesion molecule expression was measured by using chemotactic and flow cytometric assays. In another experiment, intratracheal challenge was performed by using recombinant macrophage inflammatory protein-2 (MIP-2), and BALF neutrophils were measured. RESULTS: BALF MIP-2 and cytokine-induced neutrophil chemoattractant were decreased by alcohol, and BALF from alcohol-intoxicated animals had decreased chemotactic activity for neutrophils, as well as a decreased ability to up-regulate neutrophil adhesion molecule expression, compared with controls. This decreased chemotactic activity was significantly increased in the alcohol group by repletion of chemokines to control levels. Alcohol also suppressed neutrophil recruitment after intrapulmonary challenge with MIP-2, suggesting that mechanisms other than chemokine suppression contribute to the alcohol-induced effect. CONCLUSIONS: At least two mechanisms, suppressed chemokine production and impaired neutrophil adhesion molecule expression, likely work in concert in the alcohol-intoxicated host to impair neutrophil adhesion and migration into the lung during pneumococcal infection. These alterations in neutrophil function likely increase the susceptibility of alcohol-consuming hosts to pneumonia. Publication Types: * Comparative Stu* Research Support, U.S. Gov't, P.H.S.

Acute ethanol intoxication suppresses lung chemokine production following infection with Streptococcus pneumoniae. Boé DM, S, Zhang P, Bagby GJ. Department of Physiology, Section of Pulmonary and Critical Care Medicine, Louisiana State University Health Sciences Center, New Orleans, LA 70112, USA. Alcohol intoxication impairs neutrophil function and increases host susceptibility to Streptococcus pneumoniae. In a rat model of pneumonia, the effects of acute intoxication were monitored for lung chemokine responses, neutrophil recruitment, and bactericidal activity. Alcohol delayed lung neutrophil recruitment, increased bacterial burden, and decreased survival. Before neutrophil recruitment, bronchoalveolar lavage (BAL) macrophage inflammatory protein-2 (MIP-2) and cytokine-induced neutrophil chemoattractant (CINC) were decreased by alcohol. This alcohol-induced effect was reversed at 6 h, when there were large numbers of neutrophils in control BAL fluid, compared with the alcohol-treated group. Cyclophosphamide-induced neutropenia decreased neutrophil recruitment, minimizing the effects of recruited neutrophils on chemokine levels, and extended the alcohol-induced chemokine suppression. MIP-2 and CINC mRNA contents also were suppressed by alcohol 4 and 6 h after infection. Thus, alcohol suppresses lung chemokine activity in response to S. pneumoniae, which is associated with delayed neutrophil delivery, elevated bacterial burden, and increased mortality.
