Spectrum of acute hepatitis and its clinical outcome in a central region in Tunisia

INTRODUCTION: given the lack of studies on acute hepatitis (AH) in Tunisia, we carried out this study to find the etiological spectrum and clinical profile of AH and to investigate the impact of viral etiology on the outcomes of AH. METHODS: retrospective descriptive study collecting all patients with AH from 2010 to 2017. The data were compared between two groups (viral AH and non-viral AH). RESULTS: one hundred and three patient´s files were included. The average age of our patients was 30.15 years. An etiology was found in 92 patients (89.3%). The viral etiology was found in 70 patients (76.1%). Hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV) and cytomegalovirus (CMV) were in the cause in 52, 16, 1 and 1 patient respectively. Elsewhere, it was toxic hepatitis in 10 patients (10.9%) including 7 of drug-related AH. Budd-Chiari syndrome and autoimmune hepatitis with acute onset were reported in 3 (3.3%) and 7 (7.6%) patients, respectively. Patients with viral AH were younger than those with non-viral AH (p = 10-(3)). There was more recourse to hospitalization for non-viral AH. Patients with viral AH had a higher mean aminotransferase (ALT) level than those with non-viral AH. The liver damage was more severe in the non-viral AH group with lower PT. There was more severe form, more transition to chronicity and more deaths in the non-viral AH group. Conclusion: the results found in our study concerning the distribution of the etiologies of AH as well as their evolutionary aspects are consistent with the data in the literature.
