title: New-onset diabetes and nephropathy after renal transplantation.
abstract: New-onset diabetes mellitus after transplantation (NODAT) is an important complication after kidney transplantation, responsible for increased mortality mainly related to cardiovascular events and infections. It has been also identified as an independent risk factor associated with graft loss. The varying definitions of diabetes used in the literature, and the prevalence and incidence of NODAT, are difficult to establish: it varies from 2 to 50% in the kidney transplant population. However, using the World Health Organization and the American Diabetes Association criteria, it occurs in ~15% of transplant recipients at 1 year in the USA, and ~5-10% in Europe. The main recipient-related risk factors include old age, high body weight and high body mass index (BMI) before transplantation, Afro-American or Hispanic ethnicity, hepatitis C virus (HCV) infection, and impaired fasting glucose level before transplantation. The other significant risk factors include male donor, acute rejection episodes, cytomegalovirus (CMV) infection and the immunosuppressive regimen, especially the use of tacrolimus (FK506), steroids, or mammalian target for rapamycin inhibitors. While some risk factors cannot be modified, others, such as recipient body weight, BMI, HCV or CMV infection, and immunosuppressive regimen can be controlled with an appropriate diet or treatment. Screening for impaired fasting glucose should be done before transplantation in dialysis or end-stage renal disease patients to identify patients at risk for NODAT. In patients with increased BMI, weight loss before transplantation reduces the risk of NODAT. HCV infection should be treated before transplantation. Prolonged anti-CMV prophylaxis may be used. Cyclosporine A is preferred to tacrolimus in patients at high risk of NODAT. A steroid-free regimen or early steroid withdrawal is encouraged to reduce the risk of NODAT.
