Hepatitis C virus (HCV) infection has a detrimental role on patient and graft survival after renal transplantation (RT). Some studies have also implicated HCV in the development of post-transplant diabetes mellitus (PTDM). We conducted a systematic review of the published medical literature of the relationship between anti-HCV seropositive status and DM after RT. The risk of DM occurrence in anti-HCV-positive and -negative patients after RT was regarded as the most reliable outcome end-point. We used the random effects model of DerSimonian and Laird to generate a summary estimate of the Odds Ratio (OD) of new onset DM in HCV-positive and -negative patients after kidney transplantation. Ten studies involving 2502 unique RT recipients were identified. The incidence of PTDM after RT ranged between 7.9% and 50%. The summary estimate for adjusted OR was 3.97 with a 95% confidence interval (CI) of 1.83-8.61 (p-value for homogeneity <0.0473). Thus, pooling of study results demonstrated the presence of a significant link between anti-HCV seropositive status and DM after RT. This relationship provides one potential explanation for the adverse effects of HCV on patient and graft survival after RT.
