Abstract: AIM:To observe the effect of alfacalcidol on osteoporosis induced by large dose glucocorticoid treatment in glomerulonephritis patients. METHODS: 28 patients with glomerulonephritis receiving glucocorticoids were divided into two groups randomly. 16 patients received calcium carbonate 750 mg three times plus alfacalcidol 1 μg one time orally a day (treatment group), and 12 patients received calcium carbonate 750 mg three times orally a day (control group). Bone mineral density (BMD) in the lumbar spine (L2-4) and the femoral neck were measured by dual-energy X-ray absorptiometry (DEXA). Intact parathyroid hormone (iPTH), serum albumin (ALB), serum calcium and phosphorus were detected before and 3, 6 months after treatment. RESULTS: BMD in the treatment group at the sixth month were higher than control group (lumbar spine 0.967±0.105, 0.896±0.131, P<0.05; femoral neck 1.078±0.124, 0.925±0.107, P<0.05). BMD in the control group at the sixth month were lower than those before treatment. There were no statistical differences in iPTH, ALB, serum calcium and phosphorus in two groups before and 3, 6 months after therapy. CONCLUSION: Alfacalcidol can decrease loss of bone mass in the lumbar spine and the femoral neck in the glomerulonephritis patients receiving glucocorticoid therapy.
