Objective: To assess risk factors for liver-related death, we re-evaluated, after a median follow-up of 25 years, a cohort of 70 Caucasian patients with hepatitis B e antigen (HBeAg) positive chronic hepatitis (CH) at presentation.
Methods: Follow-up studies included clinical and ultrasound examinations, biochemical and virologic tests, and cause of death.
Results: Sixty one (87%) patients underwent spontaneous HBeAg seroconversion. During a median period of 22.8 years after HBeAg seroclearance, 40 (66%) patients became inactive carriers, whereas the remaining 21 (34%) showed alanine aminotransferase elevation: 1 (1%) had HBeAg reversion, 9 (15%) detectable serum HBV-DNA but were negative for HBeAg, 8 (13%) concurrent virus(es) infection and 3 (5%) concurrent non alcoholic fatty liver disease. Liver-related death occurred in 11 (15.7%) patients, caused by hepatocellular carcinoma in 5 and liver failure in 6. The 25-year survival probability was 40% in patients persistently HBeAg positive, 50% in patients with HBeAg negative CH or HBeAg reversion and 95% in inactive carriers. Older age, male sex, cirrhosis at entry and absence of sustained remission predicted liver-related death independently. The adjusted hazard ratios (95% CI) for liver related death were 33 (3.01-363) for persistently HBeAg positive patients and 38.73 (4.65-322) for those with HBeAg negative CH or HBeAg reversion relative to inactive carriers.
Conclusion: Most patients with HBeAg seroconversion became inactive carriers with very good prognosis. The risk of liver-related mortality in Caucasian adults with CH is strongly related with sustained disease activity and ongoing high level of HBV replication independently of HBeAg status.
- HBeAg negative hepatitis
- hepatitis B e antigen seroconversion
- inactive carrier
- sustained HBV replication
- sustained alanine aminotransferase normalization
