Many chronic diseases such as malignancy, cardiovascular diseases, endothelial dysfunction, and autoimmune diseases, which have been shown to be related to vitamin D in various studies; have similar relations with CTRP-9, TNFα, and thiol-disulfide hemostasis. We aimed to contribute to the literature by evaluating the relationship between CTRP-9, TNFα, and thiol-disulfide hemostasis and vitamin D levels, which we thought may have some effects on the pathogenesis of vitamin D deficiency.
In our study, 78 female volunteers older than 18 years were included. Volunteers were divided into three groups according to the reference values of vitamin D levels. Biochemical parameters, CTRP-9, TNFα, and thiol/disulfide hemostasis tests taken from all volunteers were studied.
In this study, there was a significant difference in CTRP-9, TNFα, total thiol (TT), native thiol (NT), DIS (disulfide), TT/DIS, and NT/DIS levels in vitamin D groups (p<0.05). There was a significant negative correlation between vitamin D and TNFα and DIS, while a significant positive correlation was found with CTRP-9, TT, NT, TT/DIS, and NT/DIS (p<0.05).
It was determined that vitamin D deficiency causes a significant decrease in CTRP-9 level and a significant increase in TNFα level, as well as an increase in thiol/disulfide hemostasis in favor of disulfide, which may be a risk factor for increased oxidative stress. We considered that these changes may play mediator roles for many chronic diseases and metabolic disorders that are increasing in frequency due to vitamin D deficiency.
许多慢性疾病,如恶性肿瘤、心血管疾病、内皮功能障碍和自身免疫性疾病,在各种研究中都表明与维生素 D 有关;与 CTRP-9、TNFα 和硫醇-二硫键止血也有类似的关系。我们旨在通过评估 CTRP-9、TNFα 和硫醇-二硫键止血与维生素 D 水平之间的关系来丰富文献,我们认为这可能对维生素 D 缺乏症的发病机制有一些影响。
在我们的研究中,纳入了 78 名年龄大于 18 岁的女性志愿者。志愿者根据维生素 D 水平的参考值分为三组。研究了所有志愿者的生化参数、CTRP-9、TNFα 和硫醇/二硫键止血试验。
在本研究中,维生素 D 组的 CTRP-9、TNFα、总巯基(TT)、天然巯基(NT)、DIS(二硫化物)、TT/DIS 和 NT/DIS 水平存在显著差异(p<0.05)。维生素 D 与 TNFα 和 DIS 呈显著负相关,而与 CTRP-9、TT、NT、TT/DIS 和 NT/DIS 呈显著正相关(p<0.05)。
确定维生素 D 缺乏会导致 CTRP-9 水平显著降低,TNFα 水平显著升高,以及有利于二硫键形成的硫醇/二硫键止血增加,这可能是氧化应激增加的一个危险因素。我们认为这些变化可能在许多由于维生素 D 缺乏而日益增多的慢性疾病和代谢紊乱中发挥中介作用。
