Implications of Gender on the Outcome in Patients With Autoimmune Hepatitis

Abstract

Background: Autoimmune hepatitis (AIH) is uncommon and predominantly affects females. Data on AIH from India are scanty. We retrospectively analyzed the spectrum and outcome of adults with AIH and compared it between male and female patients. Methods: AIH was diagnosed using a simplified AIH score. For suspected seronegative AIH, the revised score was used. Standard therapies for AIH and portal hypertension were administered and response was assessed at six months. Relapse rates and five-year mortality were also evaluated. Results: Of the 157 patients with AIH, 85 (male: female 25: 60) were included in the study. The median age at diagnosis was 46 (interquartile range (IQR) 32-55.5) years in males vs 45 (IQR 34.2-54) years in females (p=0.91). A similar proportion of male and female patients presented with cirrhosis, acute severe AIH, or AIH-related acute on chronic liver failure (ACLF); Extra-hepatic autoimmune diseases were less common in male patients (16% vs 35.5% p=0.02). Other laboratory and histological features were comparable in both groups. During the median follow-up period of 51 months (IQR 45-67 months). The biochemical and clinical response at six months were seen in 64% of male patients and 63.3% of female patients (p= 0.57). Of patients, 75% relapsed in the male AIH group (12 of 16 patients) after initial remission compared to 42% in the female group (p=0.02). Five-year mortality was 14.1%, and no patient developed hepatocellular carcinoma. Conclusion: Male and female patients with AIH have similar clinical, biochemical, and histological profiles. More male patients relapsed after an initial response to therapy.

Acute Hepatitis E Virus Infection Triggering Autoimmune Hepatitis in a Patient With Chronic Liver Disease: Case Report and the Review of the Literature

“…One of the strengths of our report is that we have ruled out chronic HEV before steroid therapy. It is imperative to diagnose AIH after ruling out acute HEV infection as AIH is often associated with long-term consequences including cirrhosis and hepatocellular carcinoma [16,17]. We have a few limitations as it is a case report.…”
