[A comparison of clinical and virological characteristics of 1686 cases of HBeAg-negative and HBeAg-positive chronic hepatitis B].

ABSTRACT

OBJECTIVE: To investigate the clinical characteristics of HBeAg-negative and HBeAg-positive chronic hepatitis B (CHB). METHODS: A total of 1686 hospitalized CHB cases were analyzed retrospectively. The serum ALT values, HBV DNA levels and hepatic inflammation and fibrosis were analyzed by their serum HBeAg status. RESULTS: Among the 1686 cases, 628 (37.3%) were HBeAg-negative and 1058 (62.7%) were HBeAg-positive. Compared with HBeAg-positive group, HBeAg-negative group had a lower serum ALT and HBV DNA levels. However, hepatic necroinflammation grading and fibrosis staging in HBeAg-negative group were more advanced than that of HBeAg-positive group. Irrespective to serum HBeAg status, patients with serum HBV DNA less than 10(5)copies/ml, had a lower hepatic necroinflammation activity. CONCLUSIONS: HBeAg-positive CHB is still the predominant form of CHB in Chinese patients. Compared with patients with low HBV replication, patients with active HBV replication had a higher hepatic necroinflammation activity. The liver histological grading and staging in HBeAg-negative CHB patients were more advanced than that in HBeAg-positive patients.
