摘要

低钾血症是临床上常见的一种疾病。其潜在的病理生理学可归因于三种主要机制:钾摄入不足、泌尿或胃肠道损失过多以及跨细胞转移。肾丢失是低钾血症最常见的原因。利尿剂、矿物质皮质激素过量或皮质醇分泌过多(库欣综合征)都可能导致肾失钾。在库欣综合征患者中,异位促肾上腺皮质激素(ACTH)是最常见的原因。我们介绍了一例因异位促肾上腺皮质激素分泌导致库欣综合征而引起低钾血症和高血压的病例。

Hypokalemia Due to Ectopic Adrenocorticotropic Hormone.

Hypokalemia is a common disorder in clinical practice. The underlying pathophysiology can be attributed to 3 main mechanisms: insufficient potassium intake, excessive urinary or gastrointestinal losses, and transcellular shift. Renal loss is the most common cause of hypokalemia. Renal loss of potassium can occur due to diuretics, mineralocorticoid excess or hypercortisolism (Cushing syndrome). Among patients with Cushing syndrome, ectopic adrenocorticotropic hormone (ACTH) is the most frequent cause. We present a case of hypokalemia and hypertension due to ectopic ACTH production leading to Cushing syndrome.
