Abstract
Successful kidney transplantation leads to restoration of renal function. Some metabolic disorders from chronic renal failure may persist and new metabolic abnormalities can develop (obesity, diabetes, hypertension, bone disease, and anemia). Additionally, influence of immunosuppressive drugs (corticosteroids, cyclosporine A, tacrolimus, and rapamycin) may aggravate the course of diabetes, hypertension, and dyslipidemia. Nutritional management of renal transplantation is divided into the pretransplant period, transplant surgery, and early and late posttransplant period. Patients in the pretransplant period in dialysis treatment may develop protein-energy malnutrition and negative nitrogen balance, with loss of lean body mass and fat deposits. Nutritional management in the early posttransplant period with a functioning kidney graft necessitates fluid and electrolyte balance control with protein intake of 1,2/kg BW/day and 30-35 kcal/kg BW/day. In a nonfunctioning kidney graft, dialysis treatment continues and the therapeutic dose of immunosuppressive drugs must be reduced. The principal objective in the late posttransplant period is the maintenance of optimal nutritional status. Nutrition is important in managing obesity, insulin resistance, diabetes, hyperlipidemia, and hypertension. Other posttransplant conditions for which diet and/or nutritional supplements may be beneficial include hypomagnesemia, hypophosphatemia, hyperuricemia, hyperkalemia, hyperhomocysteinemia, chronic renal allograft failure, renal anemia, and renal bone disease.
