Carta al Editor: Prevención de la diabetes mellitus postrasplante en el trasplante renal - ¿estamos pasando por alto la vitamina D?

post-transplant glucose control by impairing anti-inflammatory pathways, reducing insulin sensitivity, and compromising pancreatic β-cell function. These actions are particularly important in patients receiving calcineurin inhibitors and glucocorticoids, which are major contributors to impaired insulin secretion. In PTDM, vitamin D status merits renewed attention as a modifiable factor influencing post-transplant glycemic control. Well-designed supplementation trials are needed to determine whether correcting vitamin D deficiency can meaningfully reduce PTDM incidence and improve graft outcomes.
