目的 研究昆明地区HCV感染者的病毒基因型分布,观察干扰素和利巴韦林联合治疗慢性丙型肝炎的疗效。 方法 采集60例慢性丙型肝炎患者的血液样品,采用特异性探针杂交法进行HCV基因分型,根据基因分型结果将患者分为HCV 1b型感染的长效干扰素治疗组(皮下注射聚乙二醇干扰素α-2a 180μg,1次/周)和非1b型感染的普通干扰素治疗组(皮下注射普通干扰素α-1b50μg,隔日1次),两组患者均口服利巴韦林,剂量为900 ~ 1200 mg/d。治疗前后和随访中检测患者血浆HCV RNA和ALT水平作为疗效评价的指标。用x2检验比较治疗结束后HCV 1b基因型与HCV非1b基因型感染患者肝功能异常率的差异。结果 60例患者的血液样本中,HCV 1b基因型感染患者13例(21.7%),HCV 2a基因型3例(5.0%),HCV 3a基因型10例(16.7%),HCV 3b基因型29例(48.3%),HCV 6a基因型5例(8.3%);60例患者均完成治疗48周,长效干扰素治疗组和普通干扰素治疗组获得持续病毒学应答率分别为46.1%、74.5%;获得早期病毒学应答的患者全部获得持续病毒学应答。长效干扰素治疗组和普通干扰素治疗组在治疗后肝功能仍异常的患者分别占15.4%、14.9%,两组比较,x2=0.01,P>0.05,差异无统计学意义。结论 (1)昆明地区HCV感染基因型以3b和1b为主;(2)聚乙二醇干扰素α-2a联合利巴韦林治疗HCV 1b型感染患者的疗效不理想;(3)早期病毒学应答是获得持续病毒学应答的重要预测因素。
目的 研究昆明地區HCV感染者的病毒基因型分佈,觀察榦擾素和利巴韋林聯閤治療慢性丙型肝炎的療效。 方法 採集60例慢性丙型肝炎患者的血液樣品,採用特異性探針雜交法進行HCV基因分型,根據基因分型結果將患者分為HCV 1b型感染的長效榦擾素治療組(皮下註射聚乙二醇榦擾素α-2a 180μg,1次/週)和非1b型感染的普通榦擾素治療組(皮下註射普通榦擾素α-1b50μg,隔日1次),兩組患者均口服利巴韋林,劑量為900 ~ 1200 mg/d。治療前後和隨訪中檢測患者血漿HCV RNA和ALT水平作為療效評價的指標。用x2檢驗比較治療結束後HCV 1b基因型與HCV非1b基因型感染患者肝功能異常率的差異。結果 60例患者的血液樣本中,HCV 1b基因型感染患者13例(21.7%),HCV 2a基因型3例(5.0%),HCV 3a基因型10例(16.7%),HCV 3b基因型29例(48.3%),HCV 6a基因型5例(8.3%);60例患者均完成治療48週,長效榦擾素治療組和普通榦擾素治療組穫得持續病毒學應答率分彆為46.1%、74.5%;穫得早期病毒學應答的患者全部穫得持續病毒學應答。長效榦擾素治療組和普通榦擾素治療組在治療後肝功能仍異常的患者分彆佔15.4%、14.9%,兩組比較,x2=0.01,P>0.05,差異無統計學意義。結論 (1)昆明地區HCV感染基因型以3b和1b為主;(2)聚乙二醇榦擾素α-2a聯閤利巴韋林治療HCV 1b型感染患者的療效不理想;(3)早期病毒學應答是穫得持續病毒學應答的重要預測因素。

Objective To investigate the prevalence and distribution of HCV genotypes and the clinical effect of interferon-α combined with ribavirin treatment in chronic hepatitis C patients in Kunming. Methods 60 patients were divided into two groups based on drug therapies: PEG-interferon-α plus ribavirin treatment group for HCV 1b and interferon -α plus ribavirin treatment group for non-HCV-1b. Serum ALT levels and HCV RNA quantitatious of the patients were detected during treatment and follow-up. Results The HCV genotypes of 60 patients were determined by type specific probe assay, and five different types were found. Their overall prevalence were 21.7% for type 1b, 5% for type 2a, 16.7% for type3a, 48.3% for type 3b, and 8.3% for type 6a. Sustained viral response rates for PEG-interferon treatment group were 46.1%, for interferon treatment group were 74.4%. The abnormal rate of serum ALT after the treatment had no significant difference between HCV-1b and non-HCV-lb patients(P> 0.05). All patients with early viral responses got sustained viral response. Conclusion HCV-3b is the most dominant genotype in Kunming. The effect of PEG-interferon-α plus ribavirin treatment for genotype 1b is unsatisfactory. The early viral response is a good predictor for the responses to antiviral therapy in chronic hepatitis C patients.
