Abstract
Background
Given the increase of nonalcoholic fatty liver disease (NAFLD) in the general population, a similar rise might be expected in autoimmune hepatitis (AIH) patients.
Aims
We sought to determine the clinical outcome of patients with coincident AIH and NAFLD.
Methods
We identified all intradepartmental AIH cases, and those meeting study criteria were placed into one of three cohorts: AIH only, AIH and simple steatosis (SS), and AIH and nonalcoholic steatohepatitis (NASH). The following outcome and clinical data were analyzed: incidence of all-cause mortality, incidence of liver-related mortality, incidence of liver-related adverse outcomes, and prevalence of cirrhosis at index biopsy.
Results
Out of a total 73 study patients, 14 % classified as AIH with SS and 16 % as AIH and NASH. Fifty percent of AIH and NASH patients had cirrhosis at index biopsy as compared to 18 % of AIH-only patients (p = 0.032). Patients with AIH and NASH had a relative risk of 7.65 (95 % CI 1.43–40.8) for liver-related mortality and 2.55 (95 % CI 0.92–7.09) for liver-related adverse outcomes, as compared to the AIH-only cohort. No significant difference in outcome measures existed in comparing (AIH only) with (AIH and SS) cohorts.
Discussion
Patients with coincident AIH and NASH were more likely to present with cirrhosis and more likely to develop adverse clinical outcome with decreased survival as compared to AIH-only patients. These findings suggest that simultaneous exposure confers a clinically significant increased risk, which may warrant closer follow-up and surveillance.
