Abstract:

Objective

To systematically evaluate whether clinical randomized controlled trials can demonstrate that bisphosphonates, especially zoledronic acid, are associated with reduced mortality in patients with osteoporosis.

Methods

According to the requirements of meta-analysis, CBM, CNKI, MEDLINE, PubMed, Springer, EMBASE, Wanfang, VIP and Cochrane were analyzed Library, China Science and Technology Papers Statistics and analysis network, patent database, etc. were searched to strictly evaluate the included clinical randomized controlled trials with bisphosphonates as the main intervention measures in the treatment of osteoporosis, and included effective related data. The retrieval period was from the establishment of the database to may 2020. The NOS standard was used to evaluate the quality of the literatures that met the inclusion and exclusion criteria. RR and its 95% confidence interval were used to evaluate the association strength. According to the existence of heterogeneity, the fixed effect model was used to merge the effect amount, and the single factor sensitivity analysis method was used to analyze the sensitivity.

Results

A total of 21 articles including 42, 849 subjects, 22, 605 patients in the bisphosphonate group, 855 patients died, 20, 244 patients in the placebo group and 880 deaths in the placebo group were analyzed. The correlation between bisphosphonate therapy and total mortality was 0.949 (95% CI: 0.866, 1.040, P=0.264). The correlation between alendronate and total mortality was 0.996 (95% CI: 0.705, 1.407, P=0.982), ibandronate was RR=0.802 (95% CI: 0.496, 1.298, P=0.369), risedronate was RR=0.915 (95% CI: 0.757, 1.105, P=0.354) and zoledronate was RR=0.898 (95% CI: 0.770, 1.047, P=0.168). There was no association between bisphosphonate therapy and total mortality.

Conclusion

The meta-analysis showed that bisphosphonates did not reduce the overall mortality of patients with osteoporosis.

Key words: Osteoporosis, Bisphosphonates, Total mortality
