Abstract

Objective. Although acute hepatitis A (AH-A) is usually self-limited, the clinical manifestations can vary from mild to severe liver dysfunction. However, little is known about the simple, valuable predictors for clinical manifestation in AH-A. The objective of this study was to identify the simple clinical predictors for severe liver dysfunction and its clinical course. Material and methods. A total of 162 IgM anti-hepatitis A virus (HAV) positive patients were enrolled in the study. Severe AH-A was defined as a prothrombin time <40% of control activity. Various liver-unrelated and liver-related parameters at presentation were compared separately between the severe AH-A group and the non-severe group. Results. Mean age (±SD) was 27.5 (±7.1) years and the proportion of males was 54% (88/162). Fourteen patients (8.7%) experienced severe AH-A. Of the liver-unrelated parameters, leukopenia (<4000/µl), thrombocytopenia (<150,000/µl), and high serum C-reactive protein levels (>8 mg/l) at presentation were significant predictors for severe AH-A in a univariate analysis (p <0.05). On multivariate analysis, only thrombocytopenia was an independent predictor for severe AH-A (odds ratio (OR) 5.562, 95% confidence interval (CI) 1.153–26.834, p=0.033). Of the liver-related parameters, there were no independent predictors, as shown by multivariate analysis. The thrombocytopenia group (33%, 54/162) not only had a longer recovery time (28 days (range, 14–140) versus 37 days (20–128), p<0.001), but also more frequent complications (OR 4.632, 95% CI 1.886–11.372, p=0.001) than the non-thrombocytopenia group. Conclusions. Initial thrombocytopenia may be a simple, valuable predictor for severity and clinical course in AH-A.
