摘要:

目的 探讨血浆醛固酮/肾素浓度比值(ADRR)对原发性醛固酮增多症(PA)的诊断价值及最佳临界值。方法 选取高血压患者222例,其中PA临床确诊患者33例(CPA组)。采用化学发光法检测血浆醛固酮及肾素浓度,并计算ADRR。采用受试者工作特征(ROC)曲线评价ADRR对PA的诊断价值,并确定最佳临界值。结果 高血压患者中PA患者的比例为14.86%(33/222)。PA组卧位和立位的血浆肾素浓度均明显低于高血压组(P<0.05),ADRR则明显高于高血压组(P<0.05)。ROC曲线分析显示,血浆ADRR诊断PA卧位和立位的曲线下面积(AUC)分别为0.906和0.908;ADRR卧位的最佳临界值为31.32,敏感性和特异性分别为96.97%和73.54%;立位的最佳临界值为27.57,敏感性和特异性分别为81.82%和86.77%。结论 血浆ADRR是筛查PA的有效指标。建议在PA初筛时采用25作为立位ADRR筛查的最佳临界值。

Abstract:

Objective To investigate the role of plasma aldosterone to direct renin ratio(ADRR) in the diagnosis of primary aldosteronism(PA) and its optimal cut-off value. Methods A total of 222 hypertension patients were enrolled,and there were 33 cases of PA. Plasma aldosterone and renin were determined by chemiluminescence immunoassay. ADRR was calculated. Using receiver operating characteristic(ROC) curve,the role and cut-off value of ADRR for the diagnosis of PA were evaluated. Results The proportion of PA in hypertension patients was 14.86%(33/222). Plasma renin levels at both supine and upright positions in PA group were lower than those in hypertension group(P<0.05). ADRR in PA group was higher than that in hypertension group(P<0.05). ROC curve analysis showed that the areas under curves(AUC) of ADRR were 0.906(supine position)and 0.908(upright position). The optimal cut-off value of ADRR at supine position was 31.32. The sensitivity was 96.97%,and the specificity was 73.54%. However,the optimal cut-off value of ADRR at upright position was 27.57,the sensitivity was 81.82%,and the specificity was 86.77%. Conclusions Plasma ADRR is an effective index for PA screening,and the cut-off value 25 is optimal for screening ADRR at upright position.
