我们已经开发了一种大剂量地塞米松抑制试验,可以用单次8毫克的剂量给药过夜,并将这种新方法用于83例库欣综合征患者的鉴别诊断。在76例经手术或病理证实病因的患者中(60例为库欣病,7例为异位促肾上腺皮质激素综合征,9例为肾上腺肿瘤),血浆皮质醇水平低于基线水平的50%表明诊断为库欣病。该检测灵敏度为92%,特异性为100%,诊断准确率为93%。这些值等于或超过标准的2天测试,无论是基于尿17-羟基皮质激素或血浆皮质醇的抑制。我们的结论是,这种夜间,大剂量地塞米松抑制试验是实用和可靠的鉴别诊断库欣综合征。
We have developed a high-dose dexamethasone suppression test that can be administered overnight with a single 8-mg dose and used the new procedure in the differential diagnosis of 83 patients with Cushing's syndrome. In 76 patients with surgically or pathologically proven cause--60 with Cushing's disease, 7 with the ectopic adrenocorticotrophic hormone syndrome, and 9 with adrenal tumors--suppression of plasma cortisol levels to less than 50% of baseline indicated a diagnosis of Cushing's disease. The test had a sensitivity of 92%, a specificity of 100%, and a diagnostic accuracy of 93%. These values equal or exceed those of the standard 2-day test whether based on suppression of urinary 17-hydroxycorticosteroids or plasma cortisol. We conclude that this overnight, high-dose dexamethasone suppression test is practical and reliable in the differential diagnosis of Cushing's syndrome.
