Abstract

Plasma aldosterone levels before and after walking were compared in a series of 10 controls and 41 patients with cirrhosis of the liver. The latter were distributed in the following way: 8 had compensated cirrhosis, the remaining 33 were in a situación of hydropic decompensation, 10 with associated renal insufficiency, and 23 without. Basal aldosterone levels in compensated cirrhotics were similar to those of the controls, but these values increased significantly more than the controls following postural stimulation. Decompensated cirrhotics without renal insufficiency had significantly higher values than the controls, both in basal conditions and after stimulation. The highest values corresponded to the decompensated cirrhotic patients with renal insufficiency who were in advanced stages of liver disease. On the basis of the present findings and those of other authors, it is suggested that a certain reduction in the metabolic clearance of aldosterone appears to exist in hepatic cirrhosis. However, hormonal hyperproduction is the dominant factor in the pathogenic mechanism of secondary hyperaldosteronism. The pathogenesis of the excessive production of hormone is discussed. In conclusion, it appears that the scant affluence of sodium to the macula densa may be the primary factor in explaining this common situation in patients with cirrhosis of the liver.

摘要

对10名对照组和41名肝硬化患者在行走前后的血浆醛固酮水平进行了比较。后者的分布情况如下:8例为代偿期肝硬化,其余33例处于腹水失代偿状态,其中10例伴有肾功能不全,23例无肾功能不全。代偿期肝硬化患者的基础醛固酮水平与对照组相似,但在体位刺激后,这些值的升高幅度明显大于对照组。无肾功能不全的失代偿期肝硬化患者在基础状态和刺激后的值均显著高于对照组。最高值对应于处于肝病晚期且伴有肾功能不全的失代偿期肝硬化患者。根据目前的研究结果和其他作者的研究结果,提示肝硬化患者醛固酮的代谢清除率似乎存在一定程度的降低。然而,激素分泌过多是继发性醛固酮增多症发病机制中的主要因素。文中讨论了激素过度分泌的发病机制。总之,致密斑钠供应不足似乎是解释肝硬化患者这一常见情况的主要因素。
