摘要目的 比较泛基因型和特异基因型直接抗病毒药物(DAAs)治疗慢性HCV基因1b型感染者的病毒学应答率.方法 收集2018年1月至2019年7月就诊于山西医科大学第一医院感染科门诊的慢性HCV基因型1b型感染者,共113例,其中CHC患者89例,肝硬化患者24例,根据肝功能、肾功能、患者合并症、经济情况等采用不同DAAs治疗. 72例使用泛基因型DAAs治疗,其中43例使用索磷布韦+维帕他韦(SOF+VEL)治疗,13例使用SOF联合利巴韦林(RBV)治疗,16例使用SOF联合达拉他韦(DCV)治疗;41例使用特异基因型DAAs治疗,其中15例使用奥比帕利(OBV)联合达塞布韦(DSV)治疗,26例使用艾尔巴韦(EBR)+格拉瑞韦( GZR)治疗.采用χ2检验和配对t检验比较患者病毒学应答率和肝功能好转情况,并观察药物的不良反应.结果 113例患者DAAs治疗1周时获得超快速病毒学应答(SRVR)率达88.5%(100／113),治疗4周时快速病毒学应答( RVR)率达98.2%(111／113). 5种治疗方案在治疗1周及4周时SRVR和RVR差异无统计学意义(χ2 ＝5.95和1.04,P＞0.05),在治疗12周时完全早期病毒学应答(CEVR)和治疗结束后第12周持续病毒学应答(SVR12)发生率均为100.0%.同时,泛基因型和特异基因型药物的 SRVR和RVR发生率差异无统计学意义(χ2 ＝0.03和0.17,P＞0.05),cEVR和SVR12均能达到100.0%,患者肝脏转氨酶水平治疗后均得到改善.治疗中,5例发生轻微不良反应;1例出现溶血,更换治疗方案后治愈.结论 泛基因型和特异基因型DAAs均能实现高病毒学应答率,建议抗病毒治疗前进行基因型检测,以便精准选择治疗方案,节省经费.

abstractsObjective To evaluate the efficacy of precision therapy with direct-acting antiviral drugs (DAAs) for patients with chronic HCV gene type 1b infection.Methods One hundred and thirteen patients with chronic HCV genotype 1b infection admitted in the Department of Infectious Diseases of First Hospital of Shanxi Medical University from January 2018 to July 2019 were enrolled,including 89 patients with chronic hepatitis and 24 patients with cirrhosis.Different DAAs therapeutic schedule were taken based on liver function, kidney function, complication and treatment costs.Seventy-two patients were treated with pan-genotype drugs, including 43 patients treated with Sofosbuvir and Velpatasvir (SOF+VEL), 13 treated with Sofosbuvir and Ribavirin ( SOF +RBV), and 16 treated with Sofosbuvir and Daclatasvir ( SOF +DCV).Forty one patients were treated with specific genotype DAAs , including 15 treated with Ombitasvir and Dasabuvir (OBV+DSV), and 26 treated with Elbasvir and Grazoprevir tablets (EBR+GZR).Pair t test and Chi-square test were used to compare virological response rate , the liver function and the adverse reactions were observed.Results The super-rapid virological response (SRVR) rate with DAAs treatment at 1 week was 88.5%(100／113),and the rapid virological response ( RVR) at 4 weeks of treatment was 98.2%(111／113).There was no significant differences in SRVR and RVR among the patients treated with five treatment regimens (χ2 ＝5.95 and 1.04,P＞0.05), all the patients obtained complete early virological response (CEVR) at 12 weeks and sustained virological response ( SVR12) at 12 weeks after treatment. Besides, there were no significant differences in SRVR and RVR between pan-genotype and gene-specific drugs (χ2 ＝0.03 and 0.17, P＞0.05),both CEVR and SVR12 reached 100% in all patients.The liver transaminase levels were improved in patients undergoing pan-genotype or gene-specific drugs treatment. Mild adverse reactions were observed in 5 cases, hemolysis occurred in 1 patient and it was cured after replacement of drugs.Conclusion Both pan-genotype and specific genotypes of DAAs can achieve high virological response rates.Genotypic testing should be performed before antiviral therapy , in order to accurately select treatment options and to save costs.
