Abstract
Background
Interferon (IFN)-based therapy has been reported to reduce the liver-related mortality rate in patients with chronic hepatitis C virus (HCV) infection. However, predictors of survival and causes of death, including non-liver-related causes, have not been sufficiently investigated in chronic HCV patients who have not received IFN-based therapy.
Methods
A total of 1723 patients with chronic HCV infection who were not treated with IFN-based therapy were enrolled. Survival from liver-related diseases and non-liver-related diseases and causes of death were analyzed on the basis of the fibrosis-4 (FIB-4) index, an index of liver fibrosis.
Results
The median follow-up duration was 10.3 years. Of 465 patients who died during the follow-up period, 48.4 % died of liver-related diseases; of the remainder, 51.6 % died of non-liver-related diseases. On the basis of FIB-4 index, the liver-related mortality rate increased as the FIB-4 index increased: 16.1 % in the FIB-4 index < 1.45 group, 36.7 % in the 1.45 ≤ FIB-4 index ≤ 3.25 group, and 58.7 % in the FIB-4 index > 3.25 group (p < 0.001). Conversely, the non-liver-related mortality rate decreased as the FIB-4 index increased: 83.9, 63.3, and 41.3 %, respectively (p = 0.001). In the multivariate analysis, a FIB-4 index greater than 3.25 was identified as a risk factor independently associated with both liver-related death (hazard ratio 13.020; 95 % confidence interval 4.155–40.770) and non-liver-related death (hazard ratio 1.667; 95 % confidence interval 1.188–2.340).
Conclusions
Patients with chronic HCV infection and an elevated FIB-4 index may benefit from monitoring not only for the development of liver-related diseases but also for the development of non-liver-related diseases.
