Core Tip
Core Tip: In this study a significant number of patients who underwent kidney transplant developed post-transplant diabetes mellitus (PTDM) in the 1-year follow up. This is the first study from a tropical region showing a statistically significant association of vitamin D deficiency and PTDM. This finding is important since PTDM adversely affects graft survival and is an independent predictor of adverse cardiovascular events. It will be interesting to study the effect of vitamin D replacement on PTDM to potentially reduce the morbidity associated with PTDM.
