title: [Related factors for severe liver fibrosis in chronic hepatitis C patients with remunerated blood donation history in Jurong of Jiangsu province].
abstract: Objective:The incidence of liver fibrosis in patients with chronic hepatitis C is high. Without effective treatment, it would lead to liver cirrhosis. This study is to identify the related factors for the incidence of liver fibrosis in patients with chronic hepatitis C in order to make early intervention treatment and reduce the case fatality rate.Methods:This cross-sectional survey was conducted in adults aged ≥50 years with local residence for more than 5 years in Jurong of Jiangsu province from March to May in 2015, the patients infected with hepatitis C virus through remunerated blood donation were screened and included in the analysis. Descriptive statistical analysis was done to compare the differences in the incidence of liver fibrosis among the patients with different age, sex and education level or co-infected with hepatitis B virus or not. The risk factors for severe liver fibrosis were identified with univariate and multivariate logistic regression analysis. Liver fibrosis was diagnosed by using FIB-4 index method.Results:A total of 719 patients with chronic hepatitis C were surveyed. Severe liver fibrosis developed in 285 of the 719 patients, in whom 21.84%was males. Multivariate logistic regression analysis showed that the patients with higher education level (OR=0.65, 95%CI: 0.47-0.90) and with access of antiviral therapy (OR=0.33, 95%CI: 0.22-0.49) had lower risk for severe liver fibrosis, the patients with high fasting blood glucose level (OR=1.80, 95% CI: 1.19-2.77) and abnormal white blood cell count (OR=2.77, 95% CI: 1.95-3.90) had higher risk for severe liver fibrosis.Conclusions:The incidence of severe liver fibrosis in patients with hepatitis C was affected by many factors. Higher education level and antiviral therapy were the protective factors, but high fasting blood glucose level and abnormal white blood cell count were the risk factors.
