Abstract: AIM: To observe the change of bone mineral density, insulin-like growth factors and other biochemical markers of bone metabolism before and after treatment with bisphosphonates in maintenance hemodialysis (MHD) patients with osteoporosis. METHODS: 45 hemodialysis patients with abnormal bone mass (osteopenia or osteoporosis),in addition to the supplement of calcium and calcitriol, using alendronate 70 mg/weeks, before and after 12 months treatment, the bone mineral density(BMD), serum insulin-like growth factor-1, procollagen typeⅠN-terminal propeptide(PINP) and C-terminal telopeptide of type I collagen(CTX) were detected,respectively,and the adverse drug reactions were recorded. RESULTS: Compared with the pre-treatment,the levels of serum IGF-1,the hip (femoral neck,greater trochanter,total hip) BMD were increased(P<0.05 or P<0.01);and the levels of serum PINP,CTX were decreased in pre-treatment(P<0.01).There is no significant different in the change of the lumbar spine BMD pre-and post-treatment(P>0.05).Mild gastrointestinal symptoms were found in individual patients. CONCLUSION: In MHD patients with osteoporosis,the treatment of bisphosphonates can reduce bone turnover and bone loss with good safety.Bisphosphonates may improve MHD osteoporotic patients' bone mass by increasing the IGF-1 which is closely related to bone formation.
