The influence of ribavirin trough concentrations (RBV C(trough)) on the risk of hepatitis C virus (HCV) relapse was retrospectively analyzed in 99 HIV-HCV-coinfected patients who achieved end-of-treatment response with pegylated alpha interferon plus weight-based RBV. The independent predictors (odds ratio [OR] [95% confidence interval (CI)]) of HCV relapse were RBV plasma C(trough) of <2.5 microg/ml (4.5 [1.3 to 15.5]), baseline serum HCV RNA (2.5 [1.2 to 5.1]), and HCV genotype 1 or 4 (13.3 [2.6 to 66.7]). Monitoring of RBV C(trough) may permit early adjustment of RBV dosage to avoid HCV relapse.
回顾性分析了 99 例接受聚乙二醇干扰素α联合基于体重的利巴韦林治疗并获得治疗结束时应答的 HIV-HCV 共感染患者,分析利巴韦林谷浓度(RBV C(trough))对丙型肝炎病毒(HCV)复发风险的影响。HCV 复发的独立预测因子(比值比[OR] [95%置信区间(CI)])为 RBV 血浆 C(trough) <2.5μg/ml(4.5 [1.3 至 15.5])、基线血清 HCV RNA(2.5 [1.2 至 5.1])和 HCV 基因型 1 或 4(13.3 [2.6 至 66.7])。监测 RBV C(trough) 可能有助于早期调整 RBV 剂量以避免 HCV 复发。
