Abstract
Background Argentina is considered a region of low seroprevalence of hepatitis E virus (HEV), however; no studies have evaluated its burden among acute hepatitis cases. OBJECTIVES We aimed to estimate the proportion of acute HEV and outcome in a cohort of patients with acute hepatitis from 6 liver units in the Metropolitan area of Buenos Aires (MABA). STUDY DESIGN We performed a prospective cohort study including patients ≥18 years with acute hepatitis (increase in transaminases x 5 ULN) fromJuly 2016 to May 2018. Severe hepatitis was defined as acute hepatitis + INR> 1.5 and acute liver failure as severe hepatitis + encephalopathy. In patients in whom other etiologies were excluded, HEV tests were performed: anti-HEV IgM/G and HEV-RNA in serum and feces. RESULTS Overall, 268 patients with acute hepatitis were included in the study. The most frequent etiologies of acute hepatitis were hepatitis B (67patients, 25 %), hepatotoxicity (65, 24 %) and autoimmune hepatitis (26, 10 %). Acute HEV infection was confirmed in 8 (2.98 %; 95 %CI 1.25-5.63) patients who tested positive for anti-HEV IgM. A total of 63 (23.5 %) patients were hospitalized and 9 (3.3 %) patients died. Overall, 48 (18 %) patients developed severe hepatitis, 6 (2.2 %) have acute liver failure, 6 (1.9 %) underwent liver transplantation and 9 (3.4 %) patients died. CONCLUSIONS the proportion of acute HEV in MABA was low during the period studied. We believe our findings will aid physicians prioritize other etiologies of acute hepatitis over HEV in order to optimize diagnostic resources and offer better care to their patients.
