众所周知,甲状腺功能亢进症(甲亢)是引起骨质疏松的原因之一,作者为研究自发性亚临床甲亢(甲状腺激素水平正常,而 TSH 受抑制,<0.1mU/L)能否影响骨密度而进行本研究。对象及方法未治疗的多发性甲状腺结节伴亚临床甲亢妇女77例。所有病人经~(99m)Tc 扫描证实有多发性甲状腺结节,血清 FT_4正常,血清 TSH 正常或受抑制(<3.5mU/L)。当血清TSH<0.1mU/L 时,测定血清 T_3,以排除“T_3型甲亢”。患者分为两组:①组亚临床甲亢23例(6例绝经前,17例已绝经1.6～23.7年),平均年龄57.2(37～70.7)岁.体重67.9±1.8kg;②组甲状腺功能正常的甲状腺肿54例(29例绝
It is well-known that hyperthyroidism (Hyperthyroidism) is one of the causes of osteoporosis. To investigate whether spontaneous subclinical hyperthyroidism (thyroid hormone levels are normal and TSH is inhibited, <0.1 mU / L) can affect bone mineral density Conducted this study. Subjects and Methods Untreated multiple thyroid nodules with subclinical hyperthyroidism in 77 women. All patients had multiple thyroid nodules confirmed by ~ (99m) Tc scan, normal serum FT_4 and normal or suppressed serum TSH (<3.5mU / L). When serum TSH <0.1mU / L, serum T_3 was measured to exclude “T_3 hyperthyroidism.” The patients were divided into two groups: (1) group of 23 patients with subclinical hyperthyroidism (6 premenopausal and 17 menopause from 1.6 to 23.7 years) with an average age of 57.2 (37-70.7) years and a weight of 67.9 ± 1.8 kg; ②the thyroid function was normal Goiter in 54 cases (29 cases never
