Abstract
Background: Denosumab has been reported to improve bone mineral density (BMD), but the clinical impact of denosumab on osteoporosis in kidney transplant recipients (KTRs) remains controversial.
Methods: We analyzed 98 KTRs who used denosumab from 2018 to 2023. We investigated the change in BMD, laboratory findings, complications of denosumab, fracture risk assessment tool (FRAX) score, acute rejection within 1 year, and graft failure.
Results: Mean T-scores at 1 year after denosumab were significantly increased compared to mean T-scores pre-denosumab at the femur neck and spine area, respectively (-2.68 ± 0.68 vs. -2.81 ± 0.68, p < 0.001; -2.78 ± 0.96 vs. -3.21 ± 1.00, p < 0.001). The levels of calcium and phosphorus significantly decreased and those of vitamin D significantly increased at 1 year after denosumab, but there were no significant differences in parathyroid hormone, allograft function, and tacrolimus trough level. There were no recurrent fractures among 12 KTRs with a history of fracture, but three de novo fractures happened. Cardiovascular events occurred in three patients. Denosumab-induced hypocalcemia developed in eight patients, but severe hypocalcemia was observed in only one patient. Acute kidney injury did not happen. Urinary tract infection (UTI) occurred in 17 patients. Arthralgia occurred in four patients. FRAX score was significantly decreased after denosumab. Acute rejection within 1 year after denosumab developed in three patients. There was no graft failure.
Conclusion: The use of denosumab in KTRs is effective and safe for the treatment of osteoporosis and prevention of fracture, but it should be carefully monitored for complications, especially UTI.
期刊介绍：
Kidney Research and Clinical Practice (formerly The Korean Journal of Nephrology; ISSN 1975-9460, launched in 1982), the official journal of the Korean Society of Nephrology, is an international, peer-reviewed journal published in English. Its ISO abbreviation is Kidney Res Clin Pract. To provide an efficient venue for dissemination of knowledge and discussion of topics related to basic renal science and clinical practice, the journal offers open access (free submission and free access) and considers articles on all aspects of clinical nephrology and hypertension as well as related molecular genetics, anatomy, pathology, physiology, pharmacology, and immunology. In particular, the journal focuses on translational renal research that helps bridging laboratory discovery with the diagnosis and treatment of human kidney disease. Topics covered include basic science with possible clinical applicability and papers on the pathophysiological basis of disease processes of the kidney. Original researches from areas of intervention nephrology or dialysis access are also welcomed. Major article types considered for publication include original research and reviews on current topics of interest. Accepted manuscripts are granted free online open-access immediately after publication, which permits its users to read, download, copy, distribute, print, search, or link to the full texts of its articles to facilitate access to a broad readership. Circulation number of print copies is 1,600.
