Evaluating the Clinical Efficacy of Teriparatide and Denosumab Combination Therapy in Postmenopausal Osteoporosis: A Systematic Review and Meta-Analysis.

Objective: This meta-analysis aims to assess the clinical effectiveness of the combination therapy involving Teriparatide (TPTD) and Denosumab (DEN) in managing postmenopausal osteoporosis (PMO). The findings provide valuable insights into clinical treatment decisions. Methods: We conducted a comprehensive search of PubMed, the Cochrane Library, Embase, and other relevant databases to gather literature concerning the treatment of PMO with TPTD and DEN. After a thorough screening, we selected and analyzed the final literature set. Information relevant to the study was extracted, and a quality assessment was carried out. The meta-analysis utilized RevMan 5.3 software to evaluate the impact of DEN combined with TPTD on parameters such as bone mineral density (BMD), tartrate-resistant acid phosphatase-5b (TRACP-5b), fracture incidence, and adverse reactions in PMO patients. Results: After the screening process, a total of 513 patients were studied across 8 studies. Among these, 259 patients received treatment involving DEN combined with TPTD (the research group), while 254 patients were subjected to different treatment regimens (the control group). As per the Cochrane Handbook's quality assessment, all included literature exhibited high overall quality. The meta-analysis demonstrated that the research group exhibited significantly higher BMD than the control group, lower TRACP-5b levels and fracture incidence (P < .05). However, the two groups had no evident difference in adverse reaction incidence (P > .05). Conclusions: The combined treatment of DEN and TPTD exhibits notable efficacy in managing PMO, warranting its promotion and use in clinical practice.
