Purpose: To evaluate the association of hepatitis B virus (HBV) genotypes, basal core promoter (BCP)/precore (PC) and S gene mutations with the clinical-epidemiological characteristics of acute hepatitis B (AHB) in Italy. Methods: During July 2005–January 2007, 103 symptomatic AHB patients were enrolled and prospectively followed up at 15 national hospitals. HBV genotypes, BCP/PC and S gene variants were determined by nested-PCR and direct sequence analysis. Results: Genotype D, A and F were detected in 49, 45 and 6% of patients, respectively. BCP, PC, and BCP plus PC variants were found in 3.1, 11.3 and 7.2% of patients, respectively. At enrollment, 68.3% of patients were hepatitis B e antigen (HBeAg)-positive and 31.7% HBeAg-negative. BCP/PC mutations were more common in HBeAg-negative than in HBeAg-positive patients (p
