低肾素性低醛固酮综合征是获得性电解质代谢紊乱。最常见于老年糖尿病患者及肾功能不全者。作者现报告2例如下: 患者男性,49岁。因患反复发作胰腺炎行全胰腺切除后继发糖尿病12年。血压正常,不伴体位性改变。血清钾平均为5.3mEq/I。患者自觉不适时检查发现心电图异常,血清钾为7.3mEq/I。随后同时测定血浆和血清钾分别为5.7mEq/I和6.4mEq/I。在食用标准糖尿病饮食条件下,取仰卧位,血浆肾素活性为1.0μg/ml/l、血清醛固酮水平为8.0μg/dl。直立位并轻度减少血容量(口服速尿)后,血浆肾素活性为1.7μg/ml/h,血清醛固酮水 Low renin hypoglycemic syndrome is an acquired electrolyte imbalance. Most common in elderly patients with diabetes and renal insufficiency. The author now reports 2 cases as follows: Male patient, 49 years old. Due to recurrent pancreatitis after pancreatic resection of secondary diabetes after 12 years. Normal blood pressure, not associated with changes in position. Serum potassium was 5.3 mEq / I on average. Patients found to be abnormal ECG examination abnormalities, serum potassium 7.3mEq / I. Subsequently, plasma and serum potassium were determined to be 5.7 mEq / I and 6.4 mEq / I, respectively. In the standard diet of diabetic diet, supine position, plasma renin activity 1.0μg / ml / l, serum aldosterone level of 8.0μg / dl. Plasma levels of renin were 1.7 μg / ml / h after erection and mild hypovolemia (oral furosemide), serum aldosterone
