BACKGROUND: Bone disease is caused not only by increased bone turnover accompanying secondary hyperparathyroidism but also by factors such as bone metabolic disorder accompanying kidney disease and postmenopausal or age-related osteoporosis in hemodialysis patients. In this study, we investigated the effects of raloxifene on bone turnover markers and bone mineral density (BMD) in female hemodialysis patients to determine involvement of estrogen deficiency in bone disease. METHODS: The subjects were 47 female patients on maintenance hemodialysis. Raloxifene hydrochloride (60 mg) was administered to 21 patients for 1 year, and these patients were compared with a control group of 26 patients. Serum levels of N-terminal cross-linking telopeptide of type I collagen (NTx), bone alkaline phosphatase, and intact parathyroid hormone were measured, and BMD was determined by quantitative heel ultrasound as the speed of sound (SOS) in the calcaneus over this period. RESULTS: NTx decreased after treatment with raloxifene for 1 year, but significantly increased in the control group. SOS increased after treatment with raloxifene for 1 year, but significantly decreased in the control group. Treatment with raloxifene resulted in a significant decrease of NTx and a significant increase of SOS in subgroups of patients aged <60 and ≥ 60 years. CONCLUSIONS: Treatment with raloxifene can suppress a rise in NTx and increase bone mineral density in patients around the time of menopause and in postmenopausal patients of advanced age. A reduction in bone mineral density caused by estrogen deficiency may be involved in the development of bone disease in female hemodialysis patients.
