Adynamia in fibromyalgia (FM) may be an expression of a functional deficit of the hypothalamic-pituitary-adrenal axis and be associated with below-normal levels of urinary cortisol. Our aim was to demonstrate that urinary cortisol was lower in patients with FM than in healthy subjects.
We measured urinary cortisol levels for a sample of 47 women aged 29 to 64 years (mean age 53 years), diagnosed with FM 2-3 years previously, and compared the results with those for a control sample of 58 healthy women of a similar age. Samples of 24-hour urine were appropriately collected and levels of urinary cortisol were measured using the fluorescence polarization immunoassay method. The mean cortisol value for the women with FM was 65.40 +/- 27.10 mug/L, significantly lower than the mean cortisol level for the control group, at 90.83 +/- 38.17 mug/L (p < 0.001).
Our study confirms that women with FM have significantly lower urinary cortisol levels than healthy women.
纤维肌痛(FM)中的肌无力可能是下丘脑 - 垂体 - 肾上腺轴功能缺陷的一种表现,并与尿皮质醇水平低于正常有关。我们的目的是证明FM患者的尿皮质醇水平低于健康受试者。
我们测量了47名年龄在29至64岁(平均年龄53岁)的女性样本的尿皮质醇水平,这些女性在2至3年前被诊断为FM,并将结果与58名年龄相仿的健康女性对照样本的结果进行比较。适当收集24小时尿液样本,并使用荧光偏振免疫分析法测量尿皮质醇水平。FM女性的平均皮质醇值为65.40±27.10μg/L,显著低于对照组的平均皮质醇水平90.83±38.17μg/L(p<0.001)。
我们的研究证实,FM女性的尿皮质醇水平显著低于健康女性。
