摘要
目的回顾分析并比较原发性醛固酮增多症(原醛症)、原发性高血压(EH)和嗜铬细胞瘤3种不同病因高血压患者血浆肾素活性(PRA)、血管紧张素Ⅱ(AngⅡ)、醛固酮水平的差异及探讨运用醛固酮/PRA比值(ARR)的不同切点在高血压人群中筛查原醛症的敏感性和特异性。方法采用放射免疫法测定北京协和医院内分泌科诊断的111例特发性醛固酮增多症(IHA)、118例分泌醛固酮的-肾上腺皮质腺瘤(APA)、98例嗜铬细胞瘤及86例EH共计413例患者卧位及立位加速尿刺激后的血浆醛固酮、AngⅡ及PRA并计算ARR。结果卧位及立位的血浆醛固酮水平在原醛症组[471(346,632)pmol/L和673(499,825)pmol/L]及嗜铬细胞瘤组[374(294,465)pmol/L和629(449,997)pmo]/L]均高于EH组[277(224,332)pmol/L和427(341,501)pmol/L],P值均〈0.01,原醛症组中的APA组[576(416,731)pmol/L和726(554,906)pmol/L]高于IHA组[399(313,504)pmol/L和609(485,776)pmol/L],P〈0.01;卧位及立位的血浆AngⅡ水平在原醛症组[43.2(26.4,74.4)ng/L和60.1(38.5,103.6)ng/L]明显低于EH组[56.7(43.3,78.9)ng/L和84.3(61.3,108.4)ng/I~]和嗜铬细胞瘤组[54.3(29.9,101.5)ng/L和102.8(49.9,167.0)ng/L],P值均〈0.01,而IHA组与APA组之间差异无统计学意义;卧位及立位的血浆PRA为嗜铬细胞瘤组[0.3(0.2,1.0)μg·L^-1·h^-1和1.4(0.6,3.4)μg·L^-1·h^-1]〉EH组[0.2(0.1,0.4)μg·L^-1·h^-1和0.6(0.4,1.0)μg·L^-1·h^-1]〉原醛症组[0.1(0.1,0.1)μg·L~·h^-1和0.2(0.1,0.3)μg·L~·h^-1],P值均〈0.01,而APA组[0.1(0.1,0.1)μg·L^-1·h^-1和0.1(0.1,0.3)μg·L^-1·h^-1]〈IHA组[0.1(0.1,0.2)μg·L^-1·h^-1和0.2(0.1,0.3)μg·L^-1·h^-1](卧位P〈0.01;立�
Objective To study on the difference of plasma renin activity (PRA), angiotensin Ⅱ (Ang Ⅱ ), and aidosterone levels in patients with essential hypertension (EH) or primary aldosteronism (PA) or pheochromocytoma (PHEO) , and to analyze the sensitivity and specificity on the diagnosis of PA among patients with hypertension with aldosterone/PRA ratio (ARR). Methods The plasma aldosterone, Ang ]l and PRA concentrations in supine and upright positions were measured by radioimmunoassay from 413 patients including idiopathic hyperaldosteronism ( IHA, n = 111 ) , aldosterone-producing adenoma (APA, n = 118) , PHEO (n =98) and EH (n =86). ARR was calculated. Results Plasma aldosterone concentrations in both of supine and uptight positions in PHEO group [ 374 (294, 465 ) pmol/L and 629 (449, 997)pmol/L] and PA group [471(346, 632) pmol/L and 673(499,825) pmol/L] were higher than those in EH group [ 277 (224, 332) pmol/L and 427 (341, 501 ) pmol/L ] (P 〈 0. 01 ). They were also higher in APA group [576(416, 731) pmol/L and 726(554, 906)pmol/L] than those in IHA group [399(313, 504) pmol/L and 609(485, 776)pmol/L ] (P〈0. 01). Ang II levels in both positions were lower in PA group [43.2(26.4, 74.4) ng/L and 60. 1 (38.5, 103.6) ng/L] than in EH group [56.7 (43.3, 78.9) ng/L and 84.3(61.3, 108.4) ng/L] or PHEO group [54.3(29.9, 101.5) ng/L and 102. 8 (49. 9,167. 0) ng/L ] (all P values 〈 0. 01 ), and there was no difference between IHA and APA group ( P 〉 0. 05 ). The PRA level in both positions of each group were PHEO group [ 0. 3 (0. 2,1.0) μg·L^-1·h^-1 and 1.4(0.6,3.4) μg·L^-1·h^-1] 〉EHgroup [0.2(0.1,0.4)μg·L^-1·h^-1 and0.6(0.4, 1.0)μg·L^-1·h^-1] (P〈0.01) 〉PA group [0.1(0. 1,0.1)μg·L^-1·h^-1 and 0.2(0.1,0.3)μg·L^-1·h^-1] (P〈0.01), and APA group [0.1(0.1, 0.1)μg·L^-1·h^-1 and0.1(0.1, 0.3)μg·L^-1·h^-1] 〈IHAgroup [0.1(0.1,
