AIH does not have a single diagnostic test. The diagnosis is by different scoring systems based on combination of biochemical, autoimmune, and histological parameters, and exclusion of other liver diseases. Autoantibodies are hallmark of autoimmune hepatitis and constitute an important part of the diagnostic work-up. We

aim to study the serological profile of AIH in a Sri Lankan cohort. Methods: AIH database of Gastroenterology clinic, Colombo North Teaching Hospital was analyzed Maraviroc order retrospectively. The Revised Original Scoring System of the International Autoimmune Hepatitis Group was applied to define the cases of (definite or probable) AIH. Results: 18 Patients who had complete data were analyzed. 11/17 fulfilled the criteria for definite AIH and 7/18 fulfilled the criteria for

probable AIH. Of 18 patients with AIH mean age was 40.25 (SD 9.1) years and 14 (77.7%) were females. Dorsomorphin cell line Among these 18 patients only 3 (28.3%) were positive for antinuclear antibodies (ANA), 2 (11.1%) had smooth muscle antibodies (SMA) but none of these patients were positive for antibodies to liver/kidney microsome type 1 (anti-LKM-1). All these 18 patients were treated with prednisolone and azathioprine and 16 responded to treatment, but 2 patients did not respond to treatment and progressed to cirrhosis. Conclusion: Autoimmune markers appear to be less common in this cohort of patients with probable or definite AIH.

Recently detail fibrosis classification for several non invasive test such as Fib4 index have been develop but their accuracy have not been thoroughly evaluated in comparison to liver biopsy. The aim of this study was to evaluate the accuracy of the detail 上海皓元医药股份有限公司 fibrosis classification available for fib4 index with liver biopsy in Chronic Hepatitis B and C patients. Methods: In this cross sectional study, 71 patients confirmed with Hepatitis B and C, underwent liver biopsy in Adam Malik Hospital Medan since January 2011 to September 2013. Laboratory was taken such AST, ALT, platelet and personal data. Fib4 index was computed. We used predictive value, AUROC to assess the accuracy of fib4 index with liver biopsy. Results: The Fib4 index (cut off >1,45) compared to Metavir to diagnose severe fibrosis had sensitivity 78,8%, specificity 57,9%, PPV 61,9%, NPV 75,9%, LR(+) 1,87 and LR(-) 0,37. Accuracy diagnostic was 67,6%, AUROC 0,683 (95% CI:0,558–0,809) with p < 0,05 Conclusion: Fib4 index can be used for fibrosis degree classification in chronic Hepatitis B and C patients.
