BACKGROUND/AIMS: Twenty to fifty percent of patients with chronic
hepatitis C virus infection will insidiously progress to cirrhosis after
10-20 years' follow-up. The aim of this study is to retrospectively evaluate
the role of simple non-invasive blood tests in detecting the presence
of compensated liver cirrhosis in Chinese patients with chronic hepatitis
C. METHODOLOGY: One hundred and eleven biopsy-proven chronic hepatitis
C patients were enrolled, 23 (20.7%) patients showed cirrhosis with class
A in Child-Pugh's classification and were all asymptomatic. Liver biochemistry,
complete blood count, and serum N-terminal propeptide of type III procollagen
were determined and then compared between chronic hepatitis C patients
with compensated cirrhosis and without cirrhosis. Multivariate logistic
regression analysis was used to predict factors associated with compensated
cirrhosis. RESULTS: Multivariate logistic regression analysis showed platelet
count < or = 140,000/mm3 (odds ratio: 23.44, P < 0.001), globulin/albumin
ratio > or = 1 (odds ratio: 31.47, P = 0.008), and AST/ALT ratio >
or = (odds ratio: 6.58, P = 0.035) were significant predictors associated
with hepatitis C virus-related compensated cirrhosis. Platelet count <
or = 140,000/mm3 had 83% sensitivity and 85% specificity in detecting
liver cirrhosis. Globulin/albumin ratio > or = 1 had 43% sensitivity,
98% specificity and AST/ALT ratio > or = 1 had 39% sensitivity, 92%
specificity in detecting liver cirrhosis. Combined tests with AST/ALT
> or = 1 and globulin/albumin > or = 1, platelet count < or =
140,000/mm3 and globulin/albumin > or = 1 had 100% specificity, 100%
positive predictive value but lower sensitivity (22% and 39% respectively),
lower negative predictive value (83% and 86%, respectively) in detecting
hepatitis C virus-related compensated liver cirrhosis. CONCLUSIONS: Simple
blood tests with platelet count < or = 140,000/mm3, globulin/albumin
ratio > or = 1, and AST/ALT ratio > or = 1 can indicate liver cirrhosis
in follow-up patients with chronic hepatitis C.
