Incidenza, impatto clinico e fattori di rischio del diabete mellito nel paziente trapiantato.

The incidence of diabetes in kidney transplant recipients is between 4 and 20% in patients previously not affected by this pathology. This difference is partially due to the immunosuppressive therapy administered. The incidence of diabetes is very high during the first quarter after the transplant, and it becomes stable during the following quarters. The presence of diabetes - evaluated by postprandial glycemia and glycated hemoglobin - should be checked quarterly during the first year after the transplant, every six months during the second year, and yearly starting from the third year. The immunosuppressive therapy (calcineurin inhibitors and steroids), familial history, age, race, and weight (BMI) are among the risk factors of diabetes post-transplant. An increased risk of rejection seems to be among the principal consequences of diabetes in transplant recipients. Moreover, these patients are more prone to infections, cardiovascular disease, and the degenerative complications of diabetes. These facts increase the risk of organ insufficiency, morbidity, and mortality. To manage diabetes in transplant recipients it is necessary to identify at-risk patients before the transplantation, thus avoiding complicated and hazardous examinations after the transplant. After the transplantation, the modifiable risk factors, such as the immunosuppressant drugs used and the control of body weight, must be checked. The control of hypertension is important as well.
