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.
ABSTRACT
Acute viral hepatitis E (HEV) is the most common form of acute viral hepatitis in India. It is associated with self-limiting disease in most cases. However, the chronic form of HEV is also being increasingly recognized. Other viral infections like the hepatitis A virus (HAV) have been implicated in inciting autoimmune hepatitis. HEV infection has been associated with the formation of circulating liver-directed autoantibodies, however autoimmune liver disease following acute HEV infection has been rarely reported. Here we present a case of a 72-year-old diabetic lady who presented to us with an asymptomatic rise of liver enzymes. Investigations suggested metabolic dysfunction associated with steatotic liver disease. After three months of the diagnosis, she developed acute-on-chronic liver failure and her anti-HEV came out positive. She was managed accordingly. Afterwards patient had persistent high liver enzymes, so she underwent a liver biopsy. Her liver biopsy was compatible with autoimmune hepatitis.
