广泛性骨质减少常见于中年和老年类风湿性关节炎(RA)患者。削弱的骨小梁可被折断,这种小梁的微小骨折积累起来可导致脊柱海绵状骨萎陷和变形,又可导致骨干高度缩短。当这些并发症引起症状时,往往大大增剧RA患者的劳动力丧失,治疗通常不能令人满意。因此,需要评价可防止或延迟骨质减少的方法。 64例用皮质类固醇治疗的50岁以上的RA患者随机分为补钙治疗组(接受微晶体羟磷灰石钙(MCHA)粉剂6g/日)和不接受补钙的对照组两组。应用前臂光吸收密度测量、骨干高度测量和背痛
Extensive osteopenia is common in middle-aged and elderly patients with rheumatoid arthritis (RA). Weakened trabecular bone can be broken, and the tiny fractures of the trabeculae can cause collapse and deformation of the spongy bone of the spine, which can lead to shortening of the backbone. When these complications cause symptoms, they often greatly exacerbate the loss of labor in RA patients and the treatment is usually not satisfactory. Therefore, there is a need to evaluate ways to prevent or delay osteopenia. Sixty-four patients with RA over 50 years old treated with corticosteroids were randomly divided into two groups: the calcium treatment group (6g / day receiving microcrystalline hydroxyapatite calcium (MCHA) powder) and the control group without calcium supplement. Forearm light absorption density measurements, bone height measurements, and back pain were applied
