Denosumab inhibits the receptor activator of nuclear factor kappa-ligand. It markedly increases bone mineral density and has been proven to reduce the risk of fractures. However, numerous adverse effects, notably hypocalcemia, are prevalent in patients with end-stage renal disease (ESRD).
To analyze the incidence and predictors of hypocalcemia caused by denosumab compared to control in patients with ESRD.
We conducted this study in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. PubMed, Scopus, Cochrane Central, and EMBASE were systematically searched from inception through March 2024. All original studies investigating the effects of denosumab on patients with ESRD compared to control were extracted. The primary outcomes of our study were the incidence of mild, severe, and very severe hypocalcemia. Secondary outcomes included serum levels of intact parathyroid hormone, calcium, and phosphate. The results were pooled and analyzed using a random-effects model.
Seven articles comprising 3240 patients were included in our study. Patients treated with denosumab had a significantly increased incidence of mild hypocalcemia [risk ratio (RR): 2.79; 95% confidence interval (CI): 0.99-7.91; P = 0.05; I² = 37%] and of very severe hypocalcemia (RR: 9.58; 95%CI: 1.58-57.98; P = 0.01; I² = 49%). However, an increase in the occurrence of severe hypocalcemia was non-significant (RR: 4.23; 95%CI: 0.47-38.34; P = 0.20; I² = 96%). Alternatively, denosumab showed a significant decrease in serum intact parathyroid hormone [mean difference (MD): -433.20, 95%CI: -775.12 to -91.28, I2 = 98%, P= 0.01], while there was a non-significant decrease in phosphate (MD: -0.47, 95%CI: -1.35 to 0.41, I2 = 88%, P = 0.30) and calcium levels (MD: -0.33, 95%CI: -0.95 to 0.29, I2 = 94%, P = 0.29).
Our study demonstrated that denosumab is significantly associated with mild and very severe hypocalcemia in patients with ESRD making it necessary to detect and prevent this side effect of treatment.
Core Tip: Denosumab is a monoclonal antibody that inhibits receptor activator of nuclear factor kappa-Β-ligand and prevents bone resorption, making it useful for treating osteoporosis. Although denosumab has an acceptable safety profile, it is known to cause hypocalcemia in patients with renal insufficiency making it contraindicated in patients with hypocalcemia. Such patients may experience muscle and joint pain. To date, very few randomized controlled trials have explored the safety of this drug in patients with end-stage renal disease or on dialysis. This meta-analysis thus appraised the safety profile of denosumab in patients with end-stage renal disease.
