Background/Aims: We evaluated the efficacy and safety of denosumab treatment in severe chronic kidney disease (CKD) patients with osteoporosis. We also investigated whether the treatment affects the coronary artery calcifications.
Methods: Twenty-seven postmenopausal women with Stage 3b?4 CKD and osteoporosis were enrolled. Twenty patients received denosumab plus calcium carbonate and vitamin D, and seven controls received calcium carbonate and vitamin D for 1 year. Dual-energy X-ray absorptiometry and coronary artery calcium (CAC) scoring computed tomography were performed before and after treatment. Hypocalcemic symptoms and serum calcium levels were evaluated.
Results: After 1 year of treatment, the percent changes of femur neck (3.6 ± 3.2% vs. -0.7 ± 4.4%, p = 0.033) and total hip (3.4 ± 3.8% vs. -1.9 ± 2.1%, p = 0.001) bone mineral density (BMD) were significantly increased in the denosumab treated group compared to the control group. However, the percent change of lumbar spine BMD did not differ between two groups (5.6 ± 5.9% vs. 2.7 ± 3.9%, p = 0.273). The percent change of bone alkaline phosphatase was significantly different in the denosumab-treated group and control group (-31.1 ± 30.0% vs. 0.5 ± 32.0%, p = 0.027). CAC scores did not differ between groups. No hypocalcemic events occurred in both groups.
Conclusions: If carefully monitored and supplemented with calcium and vitamin D, denosumab treatment for 1 year provides significant benefits in patients with Stage 3b?4 CKD and osteoporosis. However, denosumab treatment did not affect coronary artery calcifications in these patients.
