Effect of Teriparatide on pain relief, and quality of life in postmenopausal females with osteoporotic vertebral compression fractures, a retrospective cohort study.

BACKGROUND
Osteoporotic vertebral compression fracture (OVCF) is a common disease in elderly population, which could cause serious back pain and has a substantial impact on patients' health-related quality of life (HRQoL). The aim of this study was to identify the effect of Teriparatide as a conservative treatment on reducing back pain, and improving quality of life for postmenopausal women with osteoporotic vertebral fractures.


METHODS
In a 12-month, retrospective study, 112 postmenopausal women with OVCFs were assigned to Teriparatide group (20 μg Teriparatide, subcutaneous, once daily, n=38) or control group (500 mg calcium and 400-800 IU Vitamin D per day, oral administration, n=74) according to patients' choices between January 2016 and October 2018. Patient-reported outcomes scores including the visual analogue score (VAS), Oswestry disability index (ODI), and short form 36 questionnaire (SF-36) were assessed at baseline, the 3rd month, the 6th months and 1 year after treatment.


RESULTS
Treatments with Teriparatide or calcium plus vitamin D supplements had significant effect on improvement of patients' back pain as well as HRQoL, with significantly reduced VAS and ODI and increased SF-36 physical component summary (PCS) and mental component summary (MCS) scores. At the endpoint, Teriparatide showed better therapeutic effect, with greater reductions in VAS and ODI and more increases in SF-36 PCS and MCS scores. However, more adverse events (AEs) were found in Teriparatide group, but symptoms were relatively mild and of short duration.


CONCLUSIONS
In postmenopausal women with OVCFs, the consequent persistent back pain and impaired HRQoL, treatment with Teriparatide was associated with more profound therapeutic effects and more AEs compared with calcium plus vitamin D supplements.
