Abstract
Purpose
Evidence indicates a positive association between liver enzymes and the risk of death in Western countries; however, the evidence in Asian populations is scarce. We investigated the association between liver enzymes and total, cardiovascular (CVD), cancer and hepatocellular carcinoma (HCC) mortality in a cohort of Taiwanese male free of cancer at baseline.
Methods
From 1996 to 2003, 54,751 Taiwanese male aged 40–80 years without cancer completed a health screening and were followed through 2005 (5.8 ± 2.5 years of follow-up). A random cohort of 3,961 male was selected to compare to 1,864 male who died. We used Cox proportional hazards regression models to assess the risk of all-cause, cardiovascular and cancer mortality associated with alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma glutamyl transferase (GGT).
Results
In this population, higher levels of ALT, AST and GGT were significantly associated with all-cause mortality [hazard ratio (HR) 1.2, 1.8 and 1.6 for ALT, AST and GGT, respectively; all p < 0.05], cancer mortality (HR 1.8–2.8) and HCC mortality (HR 5.5–36.1). GGT was significantly associated with CVD mortality (HR 1.2).
Conclusions
In Taiwanese male free of cancer at baseline, elevations of ALT, AST and GGT were associated with future risk of all-cause death, all cancer and HCC mortality, independent of conventional risk factors, and could be used to identify male who would benefit from HCC screening. 作者: StephenW 时间: 2013-12-8 07:28
