Summary:碩士 === 高雄醫學大學 === 藥學研究所碩士在職專班 === 94 === Background: Chronic hepatitis C virus (HCV) infection affects 170 million people worldwide. The prevalence of chronic hepatitis C is 2% to 5% in Taiwan, but 20-60% in some areas. The optimal therapeutic regimen for hepatitis C is pegylated interferon in combination with ribavirin. The duration of treatment may be individualized by the genotype. Patients with genotype 1 required treatment for 48 weeks and a standard dose of ribavirin; those with HCV genotype 2 or 3 seem to be adequately treated with a low dose of ribavirin. Objectives: The objectives of this study are to analyze the predictive factors of sustained response and the relationship medication dose and adverse reaction, so as to provide references of treatment. Methods: Data was collected from an outpatient computerized prescription data base of three regional hospitals from January 1, 2002, through December 31, 2005. Patients who were diagnosed as hepatitis C and were treated by combination of peginterferon alfa 2b and ribavirin were included. The data analysis includes the relationship between therapeutic response and genotype, age, stage of fibrosis; the relationship between abnormality of laboratory data and ribavirin dose and peginterferon alfa 2b dose. Statistical methods used in this study are chi-square test, independent-samples T test and paired T test. We used SPSS (statistical package for social science) 8.0 for Windows software to compile statistics. Results and conclusions: After six months finished treatment, 46 patients are of the sustained biochemical response (47.6 % for intention-to-treat, 60.6 % for per protocol). In total 91 treated patients, there are 66 patients with abnormal white blood cell count (75.0 %), 65 patients (73.9 %) with abnormal hemoglobulin, 27 patients (64.2 %) with abnormal absolute neutrophil count, 31 patients (47.7 %) with abnormal platelet count, 8 patients (10.8%) with abnormal total bilirubin, and 2 patients (2.5 %) with abnormal thyroid stimulating hormone. The response of treatment is related to age and the genotype of hepatitis C virus (P < 0.05), but not related to gender and weight (P > 0.05). We can not conclude if the occurrences of abnormal laboratory data are related to the dosage of peginterferon alfa 2b and ribavirin.
