Mortality Risk With Autoimmune Hepatitis

R Sharma et al. Clin Gastroenterol Hepatol 2021; 19: 2636-2647. Open Access PDF: Increased Mortality Risk in Autoimmune Hepatitis: A Nationwide Population-Based Cohort Study With Histopathology

In this nationwide population-based cohort study in Sweden from 1969-2017 of 6,016
adults with histologically-confirmed AIH (all 18 years or older) and 28,146 matched general population, key findings:

  • 3,185 individuals with AIH died (41.4/1000 person-years) compared with 10,477 reference individuals (21.9/1000 person-years)
  • The 10-year cumulative incidence of death was 32.3% (95%CI [ 31.1-33.6) for AIH individuals and 14.1% (95%CI [ 13.7-14.5) for reference individuals
  • AIH individuals with cirrhosis on biopsy had a high risk of death (HR [ 4.55; 95%CI [ 3.95-5.25), while mortality risks for patients with noncirrhotic fibrosis (HR, 2.68) and inflammation without fibrosis (HR, 2.18) were similar to overall risk
  • In this cohort, 13.7% had cirrhosis at diagnosis (lower than other studies)

My take: In this study over nearly 50 years, AIH was associated with “a 2-fold increased risk of death. Risks were particularly high in individuals with cirrhosis, portal hypertension (HR, 7.55), and overlap with cholestatic liver disease.”
