Guest guest Posted March 29, 2009 Report Share Posted March 29, 2009 Hi Cathy; Liver biochemistry improvement on treatment with Imuran (azathioprine) is suggestive of autoimmune hepatitis, and so an AIH/PSC overlap (AIH/sclerosing cholangitis overlap syndrome (autoimmune sclerosing cholangitis, ASC) might be possible: _____________________________ World J. Gastroenterol. 14: 3360-3367 (2008) Autoimmune paediatric liver disease. Mieli-Vergani G, Vergani D. Institute of Liver Studies, King's College Hospital, Denmark Hill, London SE5 9RS, UK. giorgina.vergani@... Liver disorders with a likely autoimmune pathogenesis in childhood include autoimmune hepatitis (AIH), autoimmune sclerosing cholangitis (ASC), and de novo AIH after liver transplantation. AIH is divided into two subtypes according to seropositivity for smooth muscle and/or antinuclear antibody (SMA/ANA, type 1) or liver kidney microsomal antibody (LKM1, type 2). There is a female predominance in both. LKM1 positive patients tend to present more acutely, at a younger age, and commonly have partial IgA deficiency, while duration of symptoms before diagnosis, clinical signs, family history of autoimmunity, presence of associated autoimmune disorders, response to treatment, and long-term prognosis are similar in both groups. The most common type of paediatric sclerosing cholangitis is ASC. The clinical, biochemical, immunological, and histological presentation of ASC is often indistinguishable from that of AIH type 1. In both, there are high IgG, non-organ specific autoantibodies, and interface hepatitis. Diagnosis is made by cholangiography. Children with ASC respond to immunosuppression satisfactorily and similarly to AIH in respect to remission and relapse rates, times to normalization of biochemical parameters, and decreased inflammatory activity on follow up liver biopsies. However, the cholangiopathy can progress. There may be evolution from AIH to ASC over the years, despite treatment. De novo AIH after liver transplantation affects patients not transplanted for autoimmune disorders and is strikingly reminiscent of classical AIH, including elevated titres of serum antibodies, hypergammaglobulinaemia, and histological findings of interface hepatitis, bridging fibrosis, and collapse. Like classical AIH, it responds to treatment with prednisolone and azathioprine. De novo AIH post liver transplantation may derive from interference by calcineurin inhibitors with the intrathymic physiological mechanisms of T-cell maturation and selection. Whether this condition is a distinct entity or a form of atypical rejection in individuals susceptible to the development of autoimmune phenomena is unclear. Whatever its etiology, the recognition of this potentially life-threatening syndrome is important since its management differs from that of standard anti-rejection therapy.

Guest guest Posted March 29, 2009 Report Share Posted March 29, 2009 Thank you , I appreciate the information. What is throwing me off is 's liver biopsy came in negative for AIH. Do you know how reliable liver biopsies normally are? It was preformed at a good transplant center so I assumed it was done, and read correctly. I will take this study to her next appointment and discuss it. She recently was tested for celiac and carries the gene, but she does not have celiac. From this article it looks like needs to be tested for the IgA deficiency. I am grateful her gastro doctor put her on the Imuran for her colitis. It felt like she was on a runaway train leading to transplant. Hopefully this will buy her time, and her numbers will continue to improve. I am cautiously optimistic, but more hopeful then before.

Guest guest Posted March 29, 2009 Report Share Posted March 29, 2009 Dear Cathy; I am not an expert on liver biopsies, and I honestly don't know how reliable they are for AIH. I've heard that for PSC they are not always reliable for staging because the disease may not be uniform throughout the liver, and because the biopsy can sample from only a small part of the liver. But according to this article, it is the most important diagnostic procedure for AIH: Autoimmune Hepatitis: Differential Diagnoses & Workup Author: C Wolf, MD, FACP, FACG, AGAF, Medical Director of Liver Transplantation, Westchester Medical Center, Professor of Clinical Medicine, Division of Gastroenterology and Hepatobiliary Diseases, Department of Medicine, New York Medical College Coauthor(s): Unnithan V Raghuraman, MD, FRCP, FACG, FACP, Consulting Staff, Department of Gastroenterology, St Medical Center Updated: Jul 31, 2008 Overview http://emedicine.medscape.com/article/172356-overview Differential Diagnoses & Workup http://emedicine.medscape.com/article/172356-diagnosis Treatment & Medication http://emedicine.medscape.com/article/172356-treatment Follow-up http://emedicine.medscape.com/article/172356-followup (Sorry, but I am not sure whether or not you will need to register on this site to gain access to this 5-part article?)

Guest guest Posted March 29, 2009 Report Share Posted March 29, 2009 , I am very grateful for your help, thank you. I would not normally ask, but this is important, and I don't want to miss something. switched transplant centers recently due to insurance, and I feel there have been some gaps because of that. She has been through alot the last couple of years. She had 20% of her liver removed because of a CC scare, which was quiet the ordeal. Then this new problem came up. Thanks you again, Cathy Quote Link to comment Share on other sites More sharing options...
Guest guest Posted March 29, 2009 Report Share Posted March 29, 2009 Dear Cathy; I think that you are well aware that AIH often comes first and then AIH/PSC can follow, or both can be found at the same time. It is rare that PSC can come first and AIH second, but here is one report where this sequence was found: ____________________________ Eur J Gastroenterol Hepatol. 2008 Mar;20(3):232-6. Autoimmune hepatitis 2 years after the diagnosis of primary sclerosing cholangitis: an unusual overlap syndrome in a 17-year-old adolescent. Mueller T, Bianchi L, Menges M Department of Internal Medicine, Diakonie-Hospital Schwaebisch Hall, Germany. A 15-year-old girl was admitted in April 2004 owing to fatigue and loss of appetite. Her paediatrician had found elevated serum levels for alkaline phosphatase. The endoscopic retrograde cholangiography documented typical signs of primary sclerosing cholangitis with involvement of the small and large ducts. The liver biopsy revealed extensive septal and portal fibrosis. No evidence of inflammatory bowel disease was present. She was started on ursodeoxycholic acid therapy and improved clinically. After 22 months she presented again with rising transaminase levels up to 600 U/l. The second liver biopsy was strongly suggestive for autoimmune hepatitis besides the already known features of primary sclerosing cholangitis. Elevated levels of IgG, and elevated titres for ANA and antismooth muscle antibodies (ASMA) were also found. The duct irregularities seen on re-endoscopic retrograde cholangiography were slightly regredient as compared with the first investigation. We added prednisolone and azathioprine to the ursodeoxycholic acid and the transaminase levels dropped together with clinical improvement. PMID: 18301306. ____________________________ This sounds like a little bit like the sequence you are describing for ? So sorry to hear about 's CC scare! That must have been tough on both her and you. Best regards, Dave R. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted March 29, 2009 Report Share Posted March 29, 2009 pANCA positive is consistent with PSC (as well as with UC- and I believe with AIH, as well). , Mom to 18 yo daughter UC 6/95, PSC 3/09Could this possibly be PSC/ Autoimmune Cholagitis overlap given her P ANCA is positive?
