BACKGROUND/PURPOSE: Insulin resistance (IR) affects sustained virological response (SVR) to peginterferon alfa plus ribavirin (PR) in patients with chronic hepatitis C (CHC). Whether add-on oral hypoglycemic agents (OHAs) to PR improve SVR remains unclear; therefore, we conducted a prospective, randomized pilot trial on 23 consecutive patients with genotype 1 CHC and IR in Taiwan.
Patients were randomized to receive acarbose (Arm A; n = 7) or metformin (Arm B; n = 6) or pioglitazone (Arm C; n = 5) in addition to peginterferon alfa-2b (1.5 μg/kg/week) plus ribavirin (1000-1200 mg/day) or just PR (Arm D; n = 5). The primary end point was SVR, and secondary end points were viral clearance at Weeks 17, 29, and 53. There were no differences among all arms at baseline.
Using intent-to-treat analysis, SVR was observed in 66.7% (4/6), 83.3% (5/6), 66.7% (4/6), and 60% (3/5) in Arms A, B, C, and D, respectively. SVR was higher in female patients receiving OHA [90% (9/10)] than in male patients [50% (4/8)]. Results of per protocol analysis showed that SVR was 80.0% (4/5) in Arm A, 100% (5/5) in Arm B, 66.7% (4/6) in Arm C, and 60% (3/5) in Arm D. Patients receiving OHA had a higher rapid virologic response: 11/18 (61%) versus 2/5 (40%). Complete early virologic response was comparable between patients receiving OHA and PR [15/18 (83%) vs. 4/5 (80%)].
Our preliminary data show add-on OHAs to PR might achieve better early viral kinetics and SVR. However, further larger studies are needed to confirm these findings.
背景/目的:胰岛素抵抗(IR)会影响慢性丙型肝炎(CHC)患者对聚乙二醇干扰素α联合利巴韦林(PR)治疗的持续病毒学应答(SVR)。在PR治疗基础上加用口服降糖药(OHAs)是否能改善SVR尚不清楚;因此,我们对台湾地区连续23例基因1型CHC且伴有IR的患者进行了一项前瞻性随机试验。
患者被随机分为四组,除接受聚乙二醇干扰素α-2b(1.5μg/kg/周)加利巴韦林(1000 - 1200mg/天)外,A组(n = 7)加用阿卡波糖,B组(n = 6)加用二甲双胍,C组(n = 5)加用吡格列酮,D组(n = 5)仅接受PR治疗。主要终点为SVR,次要终点为第17、29和53周时的病毒清除情况。各治疗组在基线时无差异。
采用意向性分析,A、B、C、D组的SVR率分别为66.7%(4/6)、83.3%(5/6)、66.7%(4/6)和60%(3/5)。接受OHA治疗的女性患者SVR率[90%(9/10)]高于男性患者[50%(4/8)]。符合方案分析结果显示,A组SVR率为80.0%(4/5),B组为100%(5/5),C组为66.7%(4/6),D组为60%(3/5)。接受OHA治疗患者的快速病毒学应答率更高:11/18(61%)对比2/5(40%)。接受OHA治疗患者与接受PR治疗患者的完全早期病毒学应答相当[15/18(83%)对比4/5(80%)]。
我们的初步数据显示,在PR治疗基础上加用OHAs可能实现更好的早期病毒动力学和SVR。然而,需要进一步开展更大规模的研究来证实这些发现。
