Background/Aim. We evaluate the impact of combined pentoxifylline and high-dose vitamins E to standard antiviral treatment on RBV-induced haemolytic anaemia. Patients and Methods. Selected 200 naïve chronic HCV patients, were randomized to receive either the standard antiviral therapy (peginterferon α-2b and RBV) plus pentoxifylline (800 mg) and high-dose vitamin E (1000 iu) daily (combined group) or received standard antiviral therapy plus placebo only (control group). They were followed up during treatment course and for 6 months posttreatment to assess the occurrence of anaemia and virological response, respectively. Results. RBV dose modification due to anaemia were significantly less in combined group (8.5 versus 21.5%. P < .05).Withdrawal, secondary to sever anemia (Hb < 8.5 gm%), was recorded only in 6 (28.6%) patients of the control group. Both (ETR) and (SVR) were significantly higher in combined group than control group by both intention-to-treat analysis (71 versus 56%, P < .05 and 66 versus 49%, P < .05) and per-protocol analysis (85.5 versus 70.9%, P < .05 and 79.5 versus 62%, P < .05). Conclusion. Pentoxifylline and vitamin E can ameliorate RBV-associated haemolysis; improve compliance and virologic clearance when combined with the standard antiviral therapy in patients with chronic hepatitis C.
背景/目的。我们评估己酮可可碱与大剂量维生素E联合标准抗病毒治疗对利巴韦林诱导的溶血性贫血的影响。患者与方法。选取200例初治慢性丙型肝炎患者,随机分为两组,一组接受标准抗病毒治疗(聚乙二醇干扰素α-2b和利巴韦林)加己酮可可碱(800毫克)及每日大剂量维生素E(1000国际单位)(联合治疗组),另一组仅接受标准抗病毒治疗加安慰剂(对照组)。在治疗期间及治疗后6个月进行随访,分别评估贫血的发生情况及病毒学应答。结果。联合治疗组因贫血而调整利巴韦林剂量的情况显著少于对照组(8.5%对21.5%,P<0.05)。仅对照组有6例(28.6%)患者因严重贫血(血红蛋白<8.5克/分升)而停药。意向性分析显示联合治疗组的早期病毒学应答(ETR)和持续病毒学应答(SVR)均显著高于对照组(分别为71%对56%,P<0.05和66%对49%,P<0.05),符合方案分析结果同样如此(分别为85.5%对70.9%,P<0.05和79.5%对62%,P<0.05)。结论。己酮可可碱和维生素E可改善利巴韦林相关的溶血;在慢性丙型肝炎患者中与标准抗病毒治疗联合使用时可提高依从性并改善病毒清除情况。
