Abstract

Background

To elucidate the factors associated with mortality rates among older subjects with hepatocellular carcinoma (HCC) and diabetes mellitus (DM) in a triple hepatitis B virus (HBV), hepatitis C virus (HCV) and hepatitis delta virus (HDV) endemic community.

Methods

A total of 2,909 residents aged ≥45 years were screened for hepatitis B surface antigen (HBsAg), antibodies to HCV (anti-HCV) and alanine aminotransaminase (ALT) in 1997. Anti-HDV was detected in HBsAg-positive subjects. Those who expired from HCC and DM were identified from official mortality data sets (1997–2003). Survival was analyzed using the Kaplan–Meier survival curve with log-rank test and the Cox proportional hazard model.

Results

Forty-one patients died of HCC and 25 of DM during the study period. Multivariate analysis indicated that age ≥65 years (hazard ratio 3.4; 95% confidence interval 1.8–6.4), HBsAg (3.3; 1.7–6.7), anti-HCV (3.8; 1.7–8.5) and ALT ≥40 IU/L (3.7; 1.9–7.0) were independent predictors of HCC mortality, while age ≥65 years (4.8; 2.1–11.0) and anti-HCV (4.2; 1.7–10.6) were two independent predictors of DM mortality. There were synergistic effects of dual viral infections for HCC, but not for DM mortality.

Conclusions

Old age and chronic HCV infection increase the risk of HCC and DM mortality. HBsAg and ALT levels are also risk factors for HCC mortality, but not DM. The synergistic effects of dual hepatitis viral infections are demonstrable and warrant further investigation.
