Abstract

|
Background: The long-term effects of daily teriparatide (D-TPTD) and twice-weekly TPTD (W-TPTD) injections are compared among postmenopausal women with severe osteoporosis.
Methods: A total of 102 patients were enrolled and randomly allocated into two groups for the administration of either D-TPTD or W-TPTD. Treatment efficacy was measured as the percentage change in bone mineral density (ΔBMD) from baseline in the lumbar spine, total hip, and femoral neck. The findings were compared between the two groups.
Results: At 24 months after treatment, the persistence rates and medication possession ratios in the D-TPTD and W-TPTD groups were 68.6% and 56.9%, and 87.8% and 92.0%, respectively. The ΔBMD in the lumbar spine, total hip, and femoral neck were 15.6%±10.2%, 5.3%± 6.3%, and 5.5%±6.2%, respectively, in the D-TPTD group; and 9.5%±7.9%, 2.3%±6.2%, and 3.1%±7.4%, respectively, in the W-TPTD group following 24 months of treatment. The ΔBMD of the lumbar spine (P=0.008) at 24 months and total hip (P=0.024) at 18 months differed significantly between the two groups.
Conclusions: D-TPTD administration resulted in a significantly higher BMD in the lumbar spine and total hip, supporting this therapeutic regimen for postmenopausal women with severe osteoporosis.
