Core Tip
Core Tip: Vitamin D deficiency is common globally and particularly prevalent in South Asia, including among patients with kidney disease. Experimental and epidemiologic evidence links low vitamin D status with dysglycemia and type 2 diabetes, and transplant studies suggest a similar association with post-transplant diabetes mellitus. The study by Singh et al adds important data from a tropical setting and supports the view that pre-transplant vitamin D deficiency is an underused opportunity for risk stratification, targeted surveillance, and, ultimately, interventional trials to reduce the burden of post-transplant diabetes mellitus.
