SummaryBackgroundHepatitis C virus (HCV) infection can lead to increased insulin resistance, but the dynamics of insulin resistance in HCV‐infected patients receiving pegylated interferon plus ribavirin remain elusive.MethodsThis prospective study enrolled HCV‐infected patients who received pegylated interferon plus ribavirin. Patients were classified according to the attainment of sustained virological response (SVR). Insulin resistance was measured using homeostatic model assessment‐insulin resistance (HOMA‐IR). The change in HOMA‐IR at baseline, the end of treatment, and 24 weeks after the end of treatment was compared in patients who achieved SVR and those who did not.ResultsA total of 65 patients participated in this study, of which 46 (71%) achieved SVR. Overall, The HOMA‐IR changed significantly during antiviral therapy, with the median values [interquartile range (IQR)] of 3.7 (1.6–10.0) prior to the treatment, 1.5 (0.8–2.9) at the end, and 1.6 (0.9–3.1) at 24 weeks after completion of therapy. However, only patients who achieved SVR had significant off‐therapy reduction of HOMA‐IR, with median values of 1.3 (IQR, 0.7–2.6) at 24 weeks off therapy and 3.6 (IQR, 1.5–9.9) at baseline (p < 0.0001). In those without SVR, the HOMA‐IR measured 24 weeks after treatment completion (median, 2.2; IQR, 1.9–4.7) did not differ from baseline values (median, 3.9; IQR, 2.2–10.0; p = 0.5).ConclusionDual therapy with pegylated interferon plus ribavirin ameliorated IR in HCV‐infected patients, but the off‐therapy improvement of IR was limited to those who attained SVR.
