New-onset diabetes melittus (NODM) is a serious complication following transplantation. Recent studies suggest an association between hepatitis C virus (HCV) infection and DM both in nontransplant settings as well as after liver transplantation (LT). The aim of this study was to assess the prevalence of NODM among Brazilian LT recipients, analyzing possible risk factors including HCV infection. We conducted a cross-sectional study to evaluate the prevalence of NODM in 82 LT recipients with a posttransplant follow-up > or =1 year including 29 HCV-positive patients and 53 with other causes for liver disease. Patients were considered to meet the criteria for DM if they had two consecutive fasting glucose values > or =126 mg/dL or if they were taking insulin or oral hypoglycemic agents at the time of the study. The overall prevalence of NODM was 18.29% with a median interval of 20 months between LT and diagnosis of DM. The age, sex, and race distribution, immunosuppressive regimen, number of rejection episodes treated with pulse therapy, and family history of DM were similar in both groups. However, the frequency of BMI > or = 30 in the pre- and posttransplant periods was higher among patients who developed NODM (P = .02). Upon multivariate analysis of the entire cohort, HCV infection was the only significant predictor of NODM (OR = 4.31, CI = 1.17 to 15.84, P = .02). In conclusion, our study confirmed an association between HCV infection and NODM among Brazilian liver transplant recipients, suggesting that HCV infection may have a potential role in the pathogenesis of posttransplantation DM.
