Steroid induced bone loss is a serious problem in frequently relapsing nephrotic syndrome especially in growing children. In order to evaluate whether $1-(OH)D_3$ (IL Sung Pharma.Co.) is effective in preventing steroid induced bone loss, we gave $0.5{mu}g$ of $1-(OH)D_3$ for one year to forty patients with frequently relapsing nephrotic syndrome, receiving longterm prednisolone therapy (mean duration $50.12{pm}29.40$ months). We checked the following markers before and after $1-(OH)D_3$ therapy. i.e. bone mineral density(BMD) using dual energy X-ray absorptiometry(DEXA) at the 2nd to 4th lumbar spine, serum calcium, phosphorus, parathyroid hormone(PTH), osteocalcin and urine pyridinoline(U-PYD). BMD($g/cm^2$) was increased even steroid therapy from $0.71{pm}0.0;to;0.73{pm}0.0$ (p<0.05). Lumbar spine BMD is a sensitive marker for evaluating steroid induced bone loss in children receiving longterm corticosteroid therapy and that $1-(OH)D_3$ appears to be effective in treating and preventing steroid induced bone loss.
Key words: $1-{\alpha}(OH)D_3$ | Steroid | Bone mineral density | Nephrotic syndrome
