抗利尿激素分泌异常综合征(Synd-rome of inappropriate Secretion ofantiditefic hormone 简称 SIADH),又称 Schwartz—Bartter syndrome。自1957年 Schwartz&Bartter 首次报告以来,国外报告著多,而国内至今仅有2例报告(中华内科杂志18(6).1979),我区尚无报告。SIADH 是由于体内抗利尿激素(an-tidiretic hormone 简称 ADH)异常的增多,引起①肾小管对水的再吸收增强造成体内潴水过多;②肾上腺皮质分泌醛固酮的机能被抑制,肾脏贮钠的能力降低,钠从尿中排出增加,其结果出现低钠 Syndro-rome of inappropriate Secretion ofantiditefic hormone referred to as SIADH, also known as Schwartz-Bartter syndrome. Since the first report of Schwartz & Bartter in 1957, there are many reports from abroad, but there are only two reports in China so far (18 (6) .1979). There is no report in our district. SIADH is due to an increase in anomalous anti-diuretic hormone (an-tidiretic hormone) in the body, resulting in ① renal tubular reabsorption of water caused by excessive retention of the body; ② adrenal cortex secretion of aldosterone was inhibited, kidney sodium storage The ability to reduce sodium excretion from the urine increased, the results appear low sodium
