ABSTRACT
Objective To study the impact of ribavirin cumulative dose on virological response rates in genotype 1 hepatitis C virus(HCV)infected patients.Methods The medical records of 225 genotype 1 chronic hepatitis C(CHC)patients treated with peginterferon α-2a plus ribavirin were retrospectively analyzed.These patients were divided into four groups according to ribavirin cumulative dose>97%,80%-97%,60%-79%and97%(65.6%,84/128),80%-97%(60.5%,26/43),60%-79%(58.3%,21/36)(x2=9.538,P=0.023).The relapse rate was 61.5%(8/13)in group of ribavirin cumulative dose97%(20.0%,21/105),80%-97%(23.5% ,8/34),60%-79%(27.6%,8/29)(x2=10.837,P-0.013).Among patients achieved rapid virological response(RVR),SVR in groups of ribavirin cumulative dose>97%,80%-97%,60%-79%and<60 % of standard dose were 92.0%(23/25),88.9%(8/9),85.7%(6/7)and 75.0%(3/4),respectively(x2=1.098,P=0.778).Conclusiom Mlid reduction of ribavirin dose not affect SVR of genotype 1 HCV infected patients.However,the relapse rate is high and SVR is low in patients treated with ribavirin cumulative dose<60% of standard dose.
