title: Is severe renal osteodystrophy a contraindication for recombinant human growth hormone treatment?
abstract: Recent extension of the use of recombinant growth hormone (rhGH) to non-growth hormone-deficient patients necessitates close attention to possible complications in these patients, including effects on bone. Recent studies on the use of rhGH in children with chronic renal failure (CRF) provide some early data. No significant differences in radiographic osteodystrophy scores, serum calcium, phosphorus, or parathyroid hormone (PTH) levels were found between treated and untreated groups. Alkaline phosphatase increased transiently. The effect of renal osteodystrophy on growth response has not yet been reported. Animal models demonstrate that GH stimulates chondrocyte proliferation. Experimental data further suggest that GH can weaken the epiphyseal plate. Slipped capital femoral epiphysis has been reported in GH-deficient patients, before, during, and after GH therapy. In CRF patients treated with GH, slipped capital femoral epiphysis has also been reported. As renal osteodystrophy and hypocalcemia are risk factors for this condition, the relationship to GH therapy is unclear in these patients. Avascular necrosis, known to be associated with slipped capital femoral epiphysis and CRF, has also been reported in patients receiving GH, although the relationship to the therapy is unknown. Children with CRF treated with rhGH should be serially monitored for renal osteodystrophy, slipped capital femoral epiphysis, and avascular necrosis with serial radiographs and serum calcium, phosphorus, alkaline phosphatase, and PTH levels.
