- Abstract
Purpose: In this multicenter retrospective observational study, we examined the early effects of romosozumab in patients with severe osteoporosis in terms of time-course changes in bone metabolism marker, improvement in bone density, and adverse effects. Materials and Methods: Patients with severe osteoporosis were included. We investigated the progress of TRACP 5b and P1NP before and 1-2 months after the administration of romosozumab. We also investigated the bone density of lumbar spine, femoral neck, and the entire femur, measured by the DXA method, before and 5-7 months after the administration of romosozumab. Results: A total of 70 patients (7 males and 63 females, age 75.0±3.6 years) participated in this study. Significant improvements in TRACP 5b and P1NP levels were observed before and 1-2 months after romosozumab administration. The average bone density of lumbar spine, femoral neck, and the entire femur were measured before and 5-7 months after romosozumab administration; and a significant increase only observed in the lumbar spine. Conclusion: Consistent with the findings of previous clinical studies, romosozumab has both bone formation-enhancing and bone resorption effects (dual effect). In addition, romosozumab also demonstrated improvement in bone density from the early phase after the administration, though the result was only seen in the lumbar spine.
