Data regarding the impact of hepatitis C (HCV) therapy on incidence of type 2 diabetes mellitus are limited. We used the data from the longitudinal Chronic Hepatitis Cohort Study-drawn from four large US health systems-to investigate how response to HCV treatment impacts the risk of subsequent diabetes. Among HCV patients without a history of type 2 diabetes mellitus or hepatitis B, we investigated the incidence of type 2 diabetes from 12 weeks post-HCV treatment through December 2015. Cox proportional hazards models were used to test the effect of treatment status (sustained virologic response [SVR] or treatment failure) and baseline risk factors on the development of diabetes, considering any possible risk factor-by-SVR interactions, and death as a competing risk. Among 5127 patients with an average follow-up of 3.7 years, diabetes incidence was significantly lower among patients who achieved SVR (231/3748; 6.2%) than among patients with treatment failure (299/1379; 21.7%; adjusted hazard ratio [aHR] = 0.79; 95% CI: 0.65-0.96). Risk of diabetes was higher among African American and Asian American patients than White patients (aHR = 1.82 and 1.75, respectively; P < .05), and among Hispanic patients than non-Hispanics (aHR = 1.86). Patients with BMI ≥ 30 and 25-30 (demonstrated higher risk of diabetes aHR = 3.62 and 1.72, respectively; P < .05) than those with BMI < 25; patients with cirrhosis at baseline had higher risk than those without cirrhosis (aHR = 1.47). Among a large US cohort of patients treated for HCV, patients who achieved SVR demonstrated a substantially lower risk for the development of type 2 diabetes mellitus than patients with treatment failure.
