摘要
目的观察抗骨吸收药物双膦酸盐对绝经后骨质疏松症患者骨代谢状态的影响。方法本研究为回顾性研究,共收集在我院骨质疏松门诊数据库中临床资料完整的女性绝经后骨质疏松症患者152例,其中阿仑膦酸钠治疗组93例(A组),每周给予阿仑膦酸钠70 mg,一次口服;未服用阿仑膦酸钠对照组59例(B组)。分别观察治疗前和治疗后3、6、12个月骨转换生化指标:骨特异性碱性磷酸酶(BAP)、抗酒石酸酸性磷酸酶(TRAP-5b)及25羟维生素D(25(OH)VD)的变化。结果 A组患者经阿仑膦酸钠治疗3个月后BAP和TRAP-5b水平分别较治疗前下降30.60%和32.95%(P<0.001)治疗6个月时完全降至女性绝经前水平,并一直维持在此水平至治疗后12个月。B组患者治疗前后BAP和TRAP-5b水平差异无统计学意义。结论绝经后骨质疏松症患者骨代谢处于高转换状态,其BAP及TRAP-5b水平较绝经前明显升高;经阿仑膦酸钠治疗3个月后高转换状态可以明显改善,骨转换指标BAP和TRAP-5b水平回落到绝经前水平。
Objective To observe the effect of bisphosphonates ( Fosamax ) on bone turnover biomarkers in postmenopausal osteoporosis women.Methods A retrospective study was performed.A total of 152 postmenopausal osteoporosis women with complete clinical data, who were selected from the out-patients osteoporosis clinical database of our hospital, were divided into 2 groups:the alendronate treatment group (Group A, n=93) and the control group (Group B, n=59).Patients in Group A took an oral medication of 70mg alendronate tablets ( Fosamax) once a week.And patients in group B were treated without the medication of alendronate.The bone turnover biomarkers, including the changes of bone specific alkaline phosphatase ( BAP) , tartaric-resistant acid phosphatase (TRAP-5b), and 25-hydroxy vitamin D (25(OH)VD), were observed before the treatment and at the 3rd, the 6th, and 12th month after the treatment.Results After 3-month treatment, the serum levels of BAP and TRAP-5b in Group A decreased by 30.60% and 32.95%, respectively, compared with that before the treatment ( P &lt;0.001 ) , And after 6-month treatment, they totally fell back to the level similar to that in premenopausal women, and remained at this level until 12 months after the treatment.On the contrary, no significant difference of the serum levels of BAP and TRAP-5b before and after the treatment in Group B was observed.Conclusion The bone metabolism in postmenopausal osteoporosis patients is at a high turnover status, and the serum levels of BAP and TRAP-5b increased significantly compared to that in premenopausal women.After 3-month treatment with alendronate, the high turnover status can be significantly improved, and the levels of serum BAP and TRAP-5b can fall back to the premenopausal levels.
