Combination of "low-dose" ribavirin and interferon alfa-2a therapy followed by interferon alfa-2a monotherapy in chronic HCV-infected nonresponders and relapsers after interferon alfa-2a monotherapy

AIM To report on the efficacy, safety and tolerability of interferon alfa-2a combined with a "low dose" of ribavirin for relapsers and non responders to alpha interferon monotherapy.METHODS Thirty-four chronic hepatitis C virus-infected non-responders to interferon alfa2a monotherapy (a course of at least 3 months treatment) and 13 relapsers to interferon alfa 2a monotherapy (a dose of 3 to 6 million units three times per week for at least 20 weeks but not more than 18 months) were treated with the same dose of interferon alfa-2a used before (3 to 6 million units three times per week) and ribavirin (10 mg/ kg daily) for 6 months. In complete responders, interferon alfa-2a was administered for further 6 months at the same dose used before as monotherapy.RESULTS Seven (20.6%) of 34 non-responders stopped the combined therapy due to adverse events, including two patients with histological and clinical Child A cirrhosis. In 17/27 (63%)non-responders, the combined therapy was stopped after three months because of non-response. Ten of the 27 non-responders completed the 1;2-month treatment course. At a mean follow up of 28 months (16- 37 months)after the treatment, 4/10 (15%) previous non-responders still remained complete responders,All 13 previous relapsers completed the 12-month treatment course. At a mean follow up of 22months (9 - 36 months) after treatment, 6/13(46%) the previous relapsers were stillsustained complete responders.CONCLUSION Our treatment schedule of the combined therapy for 6 months of interferon alfa2a with a low dose of ribavirin (10 mg/kg/day)followed by 6 months of interferon alfa-2amonotherapy is able to induce a sustainedcomplete response rate in 15% of non-responders and 46% of relapsers with chronic hepatitis C virus-related liver diseases comparable to those obtained with the standarddoses of ribavirin 1000 - 1200 mg/day.Randomized prospective controlled trials using lower total amounts of ribavirin in combination with interferon should be performed.

HIV患者合并感染基因1和4型丙型肝炎病毒治疗效果的Meta分析

目的:探讨HIV患者共感染难治性丙型肝炎病毒(HCV,基因1型和4型)后的临床药物处理对策。方法:收集国内外2000年至今报道的干扰素或聚乙二醇干扰素联合利巴韦林治疗HCV/HIV共感染患者的随机临床对照试验结果,提取其中共感染基因1型或4型HCV的HIV患者资料。利用Meta分析方法探讨HIV患者罹患丙型肝炎后,尤其是感染基因1型或4型HCV后的治疗方案。结果:Medline文献检索结果命中88篇文献,其中6篇符合纳入标准,共提取感染基因1型或4型HCV的HIV患者资料1 131份。数据分析结果显示,聚乙二醇干扰素联合利巴韦林治疗基因1型或4型HCV的HIV患者所获得的持续病毒反应率是26%,高于干扰素联合利巴韦林治疗的反应率(8%)。聚乙二醇干扰素联合利巴韦林治疗也优于聚乙二醇干扰素单独疗法(26%vs 13%)。而聚乙二醇干扰素联合利巴韦林疗法在基因2型或3型HCV感染的HIV患者可获得55%的持续病毒反应率。干扰素或聚乙二醇干扰素联合利巴韦林治疗HCV/HIV共感染患者的副反应发生率和停药率相似。结论:聚乙二醇干扰素联合利巴韦林在治疗基因1型或4型HCV的HIV患者时优于干扰素联合利巴韦林或聚乙二醇干扰素单独疗法。

板蓝根注射液治疗单疱病毒性角膜炎临床观察(附31例报告)

目的：观察中西药联合治疗单疱病毒性角膜炎疗效。方法：６１例６１只眼随机分为板蓝根注射液治疗组（３１例）和西药治疗对照组（３０例），前者应用板蓝根注射液结膜下注射及肌内注射，西药对照组采用病毒唑结膜下注射，两者均局部应用０．１％无环鸟苷滴眼液滴眼。结果：板蓝根治疗组浅、深层治愈率分别为９４．７％及７５．０％，疗程平均１６．２天及２２．７天；西药对照组浅、深层治愈率分别为８３．３％及５８．３％，疗程平均２１．７天及２７．２天；两组治愈率及疗程差异显著（Ｐ＜０．０１）。结论：板蓝根注射液治疗可提高该病的治愈率，缩短疗程。
