Chronic urticaria is a challenging problem since the exact cause and mechanism involved in the disease development have still remained unknown. This disease is associated with mast cells activation and immunoinflammatory processes. Interestingly, dysfunctions of the neuroendocrine-immune system due to stress and other factors seem to appear as a very interesting theory for urticaria pathogenesis. Dehydroepiandrosterone and its sulfate derivative (DHEA-S) appear to have regulatory effects in immune homeostasis and are regulated by the nervous system, and it is suggested that they may be an integral element of neuroimmunomodulation. Our studies showed substantially decreased serum concentration of DHEA-S in patients with chronic urticaria. However, current knowledge prevents answering whether lower circulating DHEA-S concentration is a primary phenomenon or just an accompanying one which appears as a response of different systems to the course of the illness and may not be of any importance for the pathogenesis of urticaria whatsoever. This review is a summary of clinical research on the role of DHEA in chronic urticaria.
慢性荨麻疹是一个具有挑战性的问题,因为该病的发展涉及的确切原因和机制仍不清楚。这种疾病与肥大细胞激活和免疫炎症过程有关。有趣的是,由于压力和其他因素导致的神经内分泌-免疫功能紊乱似乎是荨麻疹发病机制的一个非常有趣的理论。脱氢表雄酮及其硫酸盐衍生物(DHEA-S)似乎对免疫稳态具有调节作用,并受神经系统调节,有研究表明它们可能是神经免疫调节的一个组成部分。我们的研究表明,慢性荨麻疹患者的血清 DHEA-S 浓度明显降低。然而,目前的知识还无法回答循环中较低的 DHEA-S 浓度是原发性现象还是仅仅是一种伴随现象,这种现象可能是不同系统对疾病过程的反应,而对于荨麻疹的发病机制可能没有任何重要意义。这篇综述总结了关于 DHEA 在慢性荨麻疹中的作用的临床研究。
