PTDM

Also written as: PTDM — Post-Transplant Diabetes Mellitus

Post-transplant diabetes mellitus, a form of new-onset diabetes occurring after organ transplantation. Often related to immunosuppressive medications and carries significant cardiovascular risk.

Full Definition

Post-transplant diabetes mellitus (PTDM) is a serious complication occurring in 10-40% of solid organ transplant recipients, typically developing within the first year after transplantation. PTDM results from multiple factors including immunosuppressive medications (particularly tacrolimus and corticosteroids), pre-existing insulin resistance, genetic predisposition, and the stress of transplantation itself. This condition significantly increases cardiovascular morbidity and mortality in transplant recipients and may lead to chronic allograft dysfunction. Management requires balancing glycemic control with immunosuppressive efficacy, often necessitating medication adjustments and intensive lifestyle interventions.

Usage

Usage note: Specific to transplant medicine context; distinguish from other forms of NODM.
