Sažetak

Over 1.5 million new cases of chronic hepatitis C virus (HCV) infection occur each
year, infecting an estimated 58 million people worldwide. We aimed to find differences in peripheral
blood count, liver enzymes and degradation products between HCV infected and healthy controls, and
their impact on detection of the disease and discrimination of the diseased from non-diseased subjects.
We performed laboratory testing for peripheral blood count, alanine aminotransferase (ALT), aspartate
aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (γ-GT) and bilirubin
in 40 HCV patients and 40 healthy controls. There were statistically significant differences in leukocytes
(p=0.001), ALT (p<0.0001), AST (p<0.0001), ALP (p<0.0001), γ-GT (p<0.0001), total bilirubin
(p<0.018) and indirect bilirubin (p<0.030) between the HCV infected and control groups. On multiple
regression, the independent variables of HCV titer (p=0.5091), granulocytes (p=0.7061) and total bilirubin
(p=0.2022) showed no impact on liver lesion estimated by a dependent variable of γ-GT. On logistic
regression, only AST [p=0.0112, odds ratio (OR)1.2161, area under the curve (AUC) 0.887] and γ-GT
(p=0.0283, OR 1.1041, AUC 0.815) showed a statistically significantly positive predicting value when
discriminating healthy subjects and diseased patients. In conclusion, HCV titer, granulocytes and total
bilirubin did not show a statistically significant impact on hepatic lesion expressed by γ-GT, whereas only
AST and γ-GT showed a statistically significant positive predicting value to discriminate infected patients
from healthy controls. Each unit increase in AST and γ-GT resulted in 21.6% and 10.4% higher possibility
of HCV infection, respectively.
