Popis: The prevalence of sarcopenia with osteoporosis results in a higher risk of falling and fractures. It was noted that patients who had completed their planned 5-year denosumab therapy course as treatment for these conditions started to sustain falls.To assess (a) whether denosumab has a unique dual effect on both bone and muscle in comparison to other anti-resorptive agents and (b) its effectiveness in the follow-up period post-treatment completion compared to other anti-resorptive agents.One hundred thirty-five patients diagnosed to have postmenopausal/senile osteoporosis and who were prescribed denosumab were compared to a control group of 272 patients stratified into 2 subgroups - 136 prescribed alendronate and 136 prescribed zoledronate. All patients were assessed for: BMD (DXA), falls risk (FRAS), fracture risk (FRAX), and sarcopenia measures. All were re-assessed after 5 years of denosumab/alendronate therapy and 3 years of zoledronate and 1 year after stopping the osteoporosis therapy.No significant baseline demographic differences between the 3 groups. On completion of the 5-year denosumab therapy, there was significant decrease in falls risk (P = 0.001) and significant improvements in all sarcopenia measures (P = 0.01). One-year post-discontinuation of denosumab, a significant worsening of both falls risk and sarcopenia measures (P = 0.01) noticed.Denosumab displayed positive impact and significant improvements in BMD and sarcopenia measures. It also enhanced multidirectional agility as depicted by Timed Up and Go (TUG). Collectively, this would explain the reduction of falls risk which got worse on stopping the medication. Key points • The coexistence of osteoporosis and sarcopenia has been recently considered in some groups as a syndrome termed 'osteosarcopenia'. • Bone and muscle closely interact with each other not only anatomically, but also at the chemical and metabolic levels. • Denosumab displayed positive impact and significant improvements in all sarcopenia measures, and enhanced multidirectional agility with consequent reduction in falls risk. • Denosumab can be considered as a first osteoporosis therapeutic option in this group of patients presenting with osteosarcopenia manifestations.
