title: Aseptic necrosis of bone following renal transplantation: relation with hyperparathyroidism.
abstract: Bone status, calcium and phosphate metabolism were prospectively evaluated in 98 renal transplant recipients with stable renal function. Aseptic necrosis of bone was found in 30 patients, leading to arthroplasty in 12 patients. Plasma parathyroid hormone and nephrogenic cyclic adenosine monophosphate (cAMP) values were greater and the duration of pre-transplant chronic renal failure longer in patients with aseptic necrosis of bone than in those who were not affected. Cumulative oral corticosteroid doses and the number of acute rejection episodes treated by intravenous methylprednisolone pulses were similar in patients with or without aseptic necrosis of bone. Hyperparathyroidism was confirmed histologically in 14 patients, comprising 4 cases of adenoma and 10 of diffuse hyperplasia. Serum parathyroid hormone correlated positively with serum creatinine (r = 0.47; P less than 0.001) and with cumulative corticosteroid dose (r = 0.30; P less than 0.003). This study suggests that hyperparathyroidism is a factor in the pathogenesis of aseptic bone necrosis. The frequency and severity of bone necrosis may be decreased by early detection and treatment of post-transplant hyperparathyroidism.
