Multiple sclerosis is one of the most salient degenerative disorders of CNS with dysregulated immune process that resulted in axonal damage and demyelination. In the present investigation, the serum level of testosterone was assessed in women who were struggling with multiple sclerosis (MS). Also, the level of omega-3, vitamin D, and the irregular menstruation in women 5 years before the onset MS symptoms were surveyed. Although the levels of omega-3 and vitamin D in women MS patients were non-significant and significantly less than the healthy ones, they were significantly less in the whole population of MS patients. However, the MS patients more experienced more irregular menstruation some years before the onset of MS with the low level of testosterone. Based on the presented findings, it might be said that the vitamin D intake has significant protective role in women and men MS patients unlike the omega-3 that had significant protective role just in men. However, vitamin D metabolism encoding genes of CYP27B1 and CYP24A1 and predicting MS risk gene of HLA-DRB1*15:01 define its fate as well. Besides, vitamin D intake, through the proliferation decrement of pro-inflammatory cells, decreases of pro-inflammatory markers (IL-6, TNF-α, INF-γ) and auto-immune pathways have potential role in recovery of irregular menstruation in women with the low level of testosterone as a red warning factor of MS development. The low level of testosterone and vitamin D consumption increase the neural damage and pro-inflammatory pathways in MS patients, and the difference among the investigations is related to the long-standing history of MS that influences severity of damage to the neural cells and biomolecules and complicate its recovery.
多发性硬化症是中枢神经系统最明显的退行性疾病之一,其免疫过程失调导致轴突损伤和脱髓鞘。在本研究中,评估了患有多发性硬化症(MS)的女性的血清睾酮水平。此外,还调查了女性在 MS 症状出现前 5 年内的ω-3、维生素 D 和不规则月经的水平。尽管 MS 患者的ω-3 和维生素 D 水平无显著差异,且显著低于健康对照组,但在整个 MS 患者群体中,其水平显著较低。然而,MS 患者在 MS 发病前几年经历了更多的不规则月经,且睾酮水平较低。基于这些发现,可以说维生素 D 摄入对女性和男性 MS 患者具有显著的保护作用,而 ω-3 仅对男性具有显著的保护作用。然而,维生素 D 代谢编码基因 CYP27B1 和 CYP24A1 以及预测 MS 风险的 HLA-DRB1*15:01 基因也决定了它的命运。此外,维生素 D 摄入通过减少促炎细胞的增殖、降低促炎标志物(IL-6、TNF-α、IFN-γ)和自身免疫途径,在降低睾酮水平的女性中对不规则月经的恢复具有潜在作用,因为睾酮水平低和维生素 D 消耗会增加 MS 患者的神经损伤和促炎途径。不同研究之间的差异与 MS 的长期病史有关,这会影响神经细胞和生物分子的损伤严重程度,并使其恢复复杂化。
