Summary
BMD changes in patients under tight control (monitored at 3-month intervals with adjustment of therapy guided by bone turnover markers) and routine management (controlled once a year) were compared. After 1 year, the femoral neck BMD increased significantly in the tight control compared to the routine management group.
Introduction
We intended to ascertain whether tight control (i.e., follow-up visits and bone turnover markers/BTM/and parathyroid hormone/PTH/monitoring at 3-month intervals) strategy achieves a statistically greater increase in bone mineral density over the observation period than standard follow-up care (i.e., bone densitometry at 1-year intervals, without BTM monitoring).
Methods
We studied involutional osteoporotic patients newly enrolled into chronic care. One hundred and eleven patients underwent tight control, while another 113 received routine treatment (with follow-up visits scheduled at > 1-year intervals). We compared the changes in bone mineral density reflected by the results of bone mineral density (BMD) measurements of the lumbar spine and of the left femoral neck. Statistical analyses were performed with version 22 of the SPSS software package.
Results
In the group of patients under tight control, baseline and follow-up median BMD values were 0.842/0.881 g/cm2 at the L1–4 vertebrae and 0.745/0.749 g/cm2 at the femoral neck. In the group under routine care, the corresponding values were 0.903/0.915 g/cm2 and 0.742/0.72 g/cm2, respectively. The relative changes of the bone mineral density of the femoral neck was significantly (p = 0.041) higher in patients under tight control than in those receiving routine care; however, BMD changes in the lumbar spine were not statistically different.
Conclusion
Our findings suggest that adopting tight control as a new therapeutic strategy might be justified in the osteoporosis management. In fact, a greater improvement of BMD can be achieved by treatment according to these principles.
