Quality of Life of Postmenopausal Women With Teriparatide, Denosumab And Alendronate: One-Year Prospective Study With A Propensity Score-Matched Comparison
Abstract Background: To evaluate and compare the effects of parathyroid hormone analogues, receptor activator of nuclear factor kappa-B ligand inhibitors (RANKL inhibitors) and bisphosphonates on the quality of life of postmenopausal women.Methods: A prospective observational study of 23 matched post-menopausal women was conducted with propensity score analysis on quality of life (QOL). Baseline and 12-month follow-up data were compared. Visual analogue scale (VAS) for back pain, the Osteoporosis Assessment Questionnaire-Physical Function (OPAQ-PF), EuroQol 5-level 5-dimension (EQ-5D-5L) questionnaire, ambulatory status assessment and Adherence Evaluation of Osteoporosis treatment (ADEOS-12) were carried out as QOL or treatment adherence measurements. A general linear model with inverse probability of treatment weighting (IPTW) adjustment with propensity score was constructed to predict one-year average back pain progression.Results: Teriparatide use was associated with significant improvements in VAS back pain (most severe pain reduced from 8.0 to 0.0, p=0.029; average pain reduced from 6.0 to 0.0, p=0.006), EQ-5D-5L general health status (EQ-5D summary index scores increased from 0.47 to 0.87, p=0.001; EQ-VAS increased from 65.0 to 80.0, p=0.008) and OPAQ physical function (from 40.0 to 79.5, p<0.001), whereas denosumab and alendronate groups only demonstrated improved OPAQ scores but worsened back pain. Baseline average VAS back pain was the only significant factor predicting one-year average back pain progression (partial eta squared=0.617, p=0.001).Conclusions: One-year continuous teriparatide treatment is most effective in improving QOL outcomes in postmenopausal osteoporotic women, but baseline average VAS back pain remained the only predictive factor for one-year back pain progression in the IPTW adjusted model.
