Prevention of osteonecrosis following renal transplantation by using vitamin D2 (ergocalciferol).

Osteonecrosis is a frequently disabling complication of renal transplantation. Thirty-one of 244 patients (12.7%), who received cadaver renal transplants from 1968 to 1978 developed an osteonecrosis. An analysis of 14 possible risk factors suggested that only the following were significantly more frequent in the osteonecrosis group: greater than 3 pulse doses of 1.2 g prednisolone, serum creatinine greater than 133 mumol/L, steroid-induced diabetes mellitus and second and subsequent transplantation. An important decline in the incidence of osteonecrosis (26.7 per cent to 6.5 per cent) was seen with prophylactic vitamin D2 treatment and the onset of osteonecrosis was on average one year later. Dangerous side effects of the large doses of vitamin D2 were minimal. Hypercalcaemia due to overdosage with vitamin D2 during simultaneous prednisolone therapy was usually mild and returned to normal in a few days by dose reduction.
