Protein catabolic rate (PCR) was measured during the first 3 to 7 weeks after kidney transplantation in nine nondiabetic patients (16–52 yr old) who were receiving azathioprine and corticosteroid immunosuppression. Five of the patients received additional amounts of corticosteroids to treat rejection episodes. The PCR paralleled the amounts of corticosteroids administered initially as prophylactic immunosuppression and later as treatment for rejection episodes. In spite of a diet containing 1.2 g of protein per kg ideal body weight, net urea generation reflected severe lean body mass breakdown, roughly equivalent in magnitude to a 50% body surface area full‐thickness burn. This catabolism was accompanied by a fall in serum albumin without significant weight loss. Hypercatabolism in the early posttransplant period is severe. After transplantation diet should be modified to try to satisfy these nitrogen demands. (Journal of Parenteral and Enteral Nutrition 10 :453–455, 1986)
