Insights

Chronic hepatitis B patients with compensated cirrhosis face significantly higher risks of decompensated cirrhosis, liver cancer, and death. Elevated alpha-fetoprotein and hepatic fibrosis severity are key prognostic factors for disease progression.

Area of Science:

  • Hepatology
  • Viral Hepatitis
  • Oncology

Background:

  • Chronic hepatitis B (CHB) is a significant global health concern.
  • Understanding disease progression in CHB patients is crucial for effective management.
  • Compensated cirrhosis is an intermediate stage that may precede decompensation.

Purpose of the Study:

  • To describe CHB disease progression in Shanghai, China.
  • To estimate risks of decompensated cirrhosis, hepatocellular carcinoma (HCC), and death.
  • To identify prognostic factors for CHB disease progression.

Main Methods:

  • Retrospective analysis of 322 biopsy-confirmed CHB cases diagnosed 1981-1993.
  • Longitudinal follow-up until 1999-2000 with clinical and laboratory assessments.
  • Statistical analyses including incidence rates, Kaplan-Meier, log-rank, and Cox regression.

Main Results:

  • Incidence rates per 1000 person-years: decompensated cirrhosis (6.3 vs 35.6), HCC (2.8 vs 8.2), death (7.6 vs 35.2) for non-compensated vs compensated cirrhosis.
  • 15-year survival rates: 88% (non-compensated) vs 56% (compensated) (P < 0.001).
  • Risk factors for decompensation/death: elevated alpha-fetoprotein (AFP), gamma-globulin, and hepatic fibrosis severity.

Conclusions:

  • Baseline elevated AFP and hepatic fibrosis severity predict higher risks of decompensated cirrhosis and death in CHB patients.
  • Compensated cirrhosis significantly increases long-term negative outcomes.
  • Provides valuable long-term outcome data for CHB patients in Shanghai.
