Abstract
The aim of this study was to assess the possible association between posttransplant diabetes mellitus (DM) and hepatitis C virus (HCV) infection in renal transplant recipients. This study included 124 patients who underwent renal transplantation between 1997 and 2002. Inclusion criteria were patients who were not diabetic prior to transplantation and posttransplant follow-up longer than 6 months. DM was defined as fasting blood glucose levels higher than 126 mg/dL on at least two occasions. HCV infection was detected using second- or third-generation ELISA methods and/or polymerase chain reactions for HCV-RNA. Twenty-five HCV positive (HCV+) patients were compared with 25 consecutive HCV negative (HCV−) transplant patients. Demographic and clinical data of the groups were compared. Posttransplantation DM was observed in 24% of the HCV+ patients. There were no statistical differences in age, gender, race, family history of DM, follow-up, or body mass index between the two groups. There was a higher prevalence of posttransplantation DM in HCV+ patients, but the difference did not reach statistical significance (24% vs 12%, P = NS). Alternatively, comparing patients of the two groups ( n = 50) who did versus not develop DM, the incidence of posttransplantation DM was higher among HCV+ patients, but the difference did not reach statistical significance (66.6% vs 46.3%, P = NS). In conclusion, there was no association between HCV infection and the development of posttransplantation DM in this cohort of renal transplant recipients. However, there was a trend that suggested an association.
