OBJECTIVE: The clinical efficacy and tolerability of denosumab in severe osteoporosis are well-known. However, the evaluation on general health and quality of life over time and compared to population norms is still lacking. We aimed at evaluating denosumab effectiveness in a real-world clinical sample with a 6-years average follow-up.

PATIENTS AND METHODS: In this retrospective-matched study with prospective data collection, a total of 101 patients affected by severe osteoporosis and treated with denosumab between 2014 and 2020 were evaluated. All patients completed the self-perceived quality of life (36-Item Short Form – SF-36) survey and visual analogue scale (VAS) before and after treatment.

RESULTS: Overall, 13 patients died of causes unrelated to the procedure, 12 stopped therapy with denosumab, and 30 did not participate in the follow-up; thus, 46 patients completed the study. There were 44 (95.7%) women and 93.4% of patients reported history of osteoporotic fractures. The mean follow-up was 59±17.8 months and the mean age at follow-up was 73.9±10.6 years. We found a significant improvement in bodily pain (baseline 53.8±33.4, follow-up 62.7±26.6; p=0.002) and in general health (baseline 35±25.4, follow-up 41.7±24.2; p=0.002) over time. The bodily pain score at follow-up was similar to the mean of the age-matched healthy population (62.7±26.6 vs. 67.6±26, p=0.374). The MCS-36 scores were higher than the normative values before treatment and at follow-up (51.6±9.8 vs. 45.8±9, p=0.004 and 50.6±11.7 vs. 45.8±9, p=0.030, respectively). The PCS-36 score at follow-up was comparable to the normative values (39.4±10.4 vs. 42.7±9, p=0.107).

CONCLUSIONS: Denosumab is effective to improve bone health and global mental and physical wellbeing, and quality of life over time.
