Analysis of clinical and virologic features in Hepatitis B e Antigen (HbeAg)-negative and HbeAg-positive Egyptian chronic Hepatitis B patients

Abstract

Background: HBeAg–negative chronic hepatitis B infection has a divergent clinical course from that of HBeAg-positive infection. Objectives: To analyze the frequency and to compare the different features of HBeAg-negative and HBeAg-positive chron- ic hepatitis B patients. Methods: One hundred and twenty one Egyptian patients with chronic hepatitis B (CHB), underwent laboratory investiga- tions and transient elastography (TE). Comparisons according to HBeAg status were conducted regarding their demograph- ic, liver biochemical and virologic characters. Results: 97 patients (80.2%) were HBeAg-negative while 24 patients (19.8%) were HBeAg-positive. HBeAg-negative pa- tients were significantly older in age than CHBeAg-positive patients (p=0.001). ALT levels in HBeAg-negative patients were significantly lower than those in HBeAg-positive patients (p=0.02), whereas serum albumin was lower in the HBeAg-posi- tive group (p=0.03). The percentage of HBV DNA higher than 20000 IU/mL in HBeAg-negative patients was lower than those in HBeAg-positive patients (p=0.24). Stages of fibrosis by TE showed that 30.9% of HBeAg-negative and 41.7% of HBeAg-positive had a fibrosis score >F2. Four patients (3.3%) were diagnosed with HCC; all of whom were HBeAg-neg- ative. Conclusion: HBeAg-negative patients compared with HBeAg-positive patients had older age, lower ALT and serum HBV- DNA levels, but more incidence of HCC. Keywords: Hepatitis B; HBeAg; fibrosis; Egypt.
