血管收缩肽内皮素-1的水平升高已在以钠潴留和/或肾血管收缩为特征的各种病理状况中得到证实,所述病理状况例如心力衰竭、肝肾综合征、肾衰竭以及在施用环孢菌素和放射造影剂期间。在本研究中,我们研究了在7名健康受试者的肾脏和内分泌系统管理内皮素-1(0.5,1.0和2.5 ng/kg/min)的影响。在内皮素-1输注期间,血浆水平从3.2 +/-0.5分别上升到5.0 +/-0.8、6.2 +/-0.5和8.5 +/-1.1 pmol/L,这些值也可以在生理和病理条件下观察到。输注低剂量内皮素-1,导致血浆水平增加两倍,钠排泄减少36%,对全身和肾脏血液动力学无显著影响。输注2.5 ng/kg/min的内皮素-1进一步增强钠潴留,此外,肾血管阻力增加37%。血压没有明显变化。用钙通道阻滞剂硝苯地平预处理引起肾血管舒张,其补偿内皮素-1引起的肾血管收缩并防止钠潴留。显然,内皮素-1参与人体容量稳态,而病理生理浓度可导致肾血管收缩和钠潴留。钙通道阻滞剂可以保护内皮素-1的这些作用。
Elevated levels of the vasocontrictor peptide endothelin-1 have been demonstrated in various pathological conditions that are characterized by sodium retention and/or renal vasoconstriction, such as heart failure, hepatorenal syndrome, renal failure and during administration of cyclosporin and radiocontrast. In the present study we studied in seven healthy subjects the renal and endocrine effects of systemic administration of endothelin-1 (0.5, 1.0 and 2.5 ng/kg/min). During endothelin-1 infusion plasma levels rose from 3.2 +/- 0.5 to respectively 5.0 +/- 0.8, 6.2 +/- 0.5 and 8.5 +/- 1.1 pmol/liter, values that can also be observed in physiological and pathological conditions. Infusion of low dosages of endothelin-1, that result in a twofold increase in plasma levels, decreased sodium excretion by 36%, without a significant effect on systemic and renal hemodynamics. Infusion of 2.5 ng/kg/min of endothelin-1 further enhanced sodium retention and, in addition, increased renal vascular resistance by 37%. Blood pressure did not change significantly. Pretreatment with the calcium channel blocker nifedipine caused renal vasodilation, which compensated for the renal vasocontriction by endothelin-1 and prevented sodium retention. Apparently, endothelin-1 participates in volume homeostasis in human, whereas pathophysiological concentrations can contribute to renal vasoconstriction and sodium retention. Calcium channel blockers may protect against these effects of endothelin-1.
