Background: Data regarding outcome of Coronavirus disease 2019 in patients with autoimmune hepatitis (AIH) are lacking.
Patients and methods:We performed a retrospective study on AIH patients with COVID-19 from 34 centres in Europe and the Americas. We analyzed factors associated with severe COVID-19 outcomes defined as the need for mechanical ventilation, intensive care admission, and/or death. The outcomes of patients with AIH were compared to a propensity-score matched cohort of non-AIH patients with chronic liver diseases (CLD) and COVID-19. The frequency and clinical significance of new-onset liver injury (alanine aminotransferase>2xupper limit of normal) during COVID-19 was also evaluated.

New-onset liver injury was observed in 37.1% (33/89) of the patients. Use of antivirals was associated with liver injury (p=0.041; odds ratio (OR) 3.36[1.05-10.78]) while continued immunosuppression during COVID-19 was associated with a lower rate of liver injury (p=0.009; OR 0.26[0.09-0.71]). The rates of severe ) and allcause mortality (10% vs 11.5%; p=0.852) were not different between AIH and non-AIH CLD.Cirrhosis was an independent predictor of severe COVID-19 in patients with AIH (p<0.001;). Continuation of immunosuppression or presence of liver injury during COVID-19 was not associated with severe COVID-19.Conclusions: This international, multi-center study reveals that patients with AIH were not at risk for worse outcomes with COVID-19 than other causes of CLD. Cirrhosis was the strongest predictor for severe COVID-19 in AIH patients. Maintenance of immunosuppression during COVID-19 was not associated with increased risk for severe COVID-19, but did lower the risk for new-onset liver injury during COVID-19.
Combination treatment of bezafibrate and UDCA is associated with marked decrease or normalization of alkaline phosphatase as early as 3 months in patients with PBC. Better biochemical response was observed in patients with early disease and lower cholestasis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
