The majority of incidentally discovered adrenal tumors are later characterized as non-producing adrenocortical adenomas (NPA). We asked whether laboratory abnormalities in parameters that reflect glucocorticoid action can be found in patients with NPA despite their nature of being clinically unapparent. Since glucocorticoids are potent immunosuppressants we studied blood counts and differential blood counts along with corticotropin and dehydroepiandrostenedione sulfate (DHEAS) blood concentrations, as well as cortisol values before and after an overnight 1 mg dexamethasone suppression test. We compared the results of normal individuals, of patients with adrenal adenomas and normal hormone profiles and with subclinical autonomous glucocorticoid hypersecretion, as well as overt cortisol excess. We found that almost all indices of the blood counts were significantly different between the patients groups. In particular, patients with adrenal non-producing adenomas already showed signs of glucocorticoid excess, including relative lymphocytopenia, lowered DHEAS, and ACTH concentrations than control individuals. We also found that the extent of lymphocytopenia correlated with the concentrations of DHEAS and ACTH, and DHEAS correlated well with ACTH. We conclude that the basal ACTH and DHEAS values along with the differential blood counts give good information on the extent of glucocorticoid excess and that silent adrenal adenomas seem to oversecrete glucocorticoids at concentrations that already alter these parameters.

DHEAS 和差异血细胞计数作为肾上腺非产生腺瘤中糖皮质激素过量的间接迹象

大多数偶然发现的肾上腺肿瘤后来被定性为不产生肾上腺皮质腺瘤 (NPA)。我们询问是否可以在 NPA 患者中发现反映糖皮质激素作用的参数的实验室异常,尽管它们的性质在临床上不明显。由于糖皮质激素是有效的免疫抑制剂,我们研究了血细胞计数和差异血细胞计数以及促肾上腺皮质激素和硫酸脱氢表雄二酮 (DHEAS) 的血液浓度,以及隔夜 1 mg 地塞米松抑制试验前后的皮质醇值。我们比较了正常个体、肾上腺腺瘤和激素正常、亚临床自主糖皮质激素分泌过多以及明显皮质醇过量的患者的结果。我们发现几乎所有的血细胞计数指标在患者组之间都有显着差异。特别是,与对照组相比,肾上腺非产生腺瘤患者已经表现出糖皮质激素过量的迹象,包括相对淋巴细胞减少、DHEAS 和 ACTH 浓度降低。我们还发现淋巴细胞减少的程度与DHEAS和ACTH的浓度相关,DHEAS与ACTH的相关性很好。我们得出结论,基础 ACTH 和 DHEAS 值以及差异血细胞计数提供了有关糖皮质激素过量程度的良好信息,并且沉默的肾上腺腺瘤似乎在已经改变这些参数的浓度下过度分泌糖皮质激素。肾上腺不产生腺瘤的患者已经表现出糖皮质激素过量的迹象,包括相对淋巴细胞减少、DHEAS 和 ACTH 浓度低于对照组。我们还发现淋巴细胞减少的程度与DHEAS和ACTH的浓度相关,DHEAS与ACTH的相关性很好。我们得出结论,基础 ACTH 和 DHEAS 值以及差异血细胞计数提供了有关糖皮质激素过量程度的良好信息,并且沉默的肾上腺腺瘤似乎在已经改变这些参数的浓度下过度分泌糖皮质激素。肾上腺不产生腺瘤的患者已经表现出糖皮质激素过量的迹象,包括相对淋巴细胞减少、DHEAS 和 ACTH 浓度低于对照组。我们还发现淋巴细胞减少的程度与DHEAS和ACTH的浓度相关,DHEAS与ACTH的相关性很好。我们得出结论,基础 ACTH 和 DHEAS 值以及差异血细胞计数提供了有关糖皮质激素过量程度的良好信息,并且沉默的肾上腺腺瘤似乎在已经改变这些参数的浓度下过度分泌糖皮质激素。和 DHEAS 与 ACTH 有很好的相关性。我们得出结论,基础 ACTH 和 DHEAS 值以及差异血细胞计数提供了有关糖皮质激素过量程度的良好信息,并且沉默的肾上腺腺瘤似乎在已经改变这些参数的浓度下过度分泌糖皮质激素。和 DHEAS 与 ACTH 有很好的相关性。我们得出结论,基础 ACTH 和 DHEAS 值以及差异血细胞计数提供了有关糖皮质激素过量程度的良好信息,并且沉默的肾上腺腺瘤似乎在已经改变这些参数的浓度下过度分泌糖皮质激素。
