Background Gut microbiota has been related to multiple sclerosis (MS) etiopathogenesis. Short-chain fatty acids (SCFA) are compounds derived from microbial metabolism that have a role in gut-brain axis. Objectives To analyse SCFA levels in plasma of MS patients and healthy donors (HD), and the possible link between these levels and both clinical data and immune cell populations. Methods Ninety-five MS patients and 54 HD were recruited. Patients were selected according to their score in the Expanded Disability Status Scale (EDSS) (49 EDSS ≤ 1.5, 46 EDSS ≥ 5.0). SCFA were studied in plasma samples by liquid chromatography-mass spectrometry. Peripheral blood mononuclear cells were studied by flow cytometry. Gender, age, treatments, EDSS and Multiple Sclerosis Severity Score (MSSS) were evaluated at the recruitment. Results Plasma acetate levels were higher in patients than in HD (p = 0.003). Patients with EDSS ≥ 5.0 had higher acetate levels than those with EDSS≤ 1.5 (p = 0.029), and HD (p = 2.97e–4). Acetate levels correlated with EDSS (r = 0.387; p = 1.08e–4) and MSSS (r = 0.265; p = 0.011). In untreated MS patients, acetate levels correlated inversely with CD4+ naïve T cells (r = − 0.550, p = 0.001) and directly with CD8+ IL-17+ cells (r = 0.557; p = 0.001). Conclusions Plasma acetate levels are higher in MS patients than in HD. In MS there exists a correlation between plasma acetate levels, EDSS and increased IL-17+ T cells. Future studies will elucidate the role of SCFA in the disease.

醋酸盐与多发性硬化症的残疾和免疫反应相关

背景 肠道微生物群与多发性硬化症 (MS) 的发病机制有关。短链脂肪酸 (SCFA) 是源自微生物代谢的化合物,在肠-脑轴中发挥作用。目的 分析 MS 患者和健康供体 (HD) 血浆中的 SCFA 水平,以及这些水平与临床数据和免疫细胞群之间的可能联系。方法 招募了 95 名 MS 患者和 54 名 HD 患者。根据他们在扩展残疾状态量表 (EDSS) 中的分数(49 EDSS ≤ 1.5, 46 EDSS ≥ 5.0)选择患者。通过液相色谱-质谱法研究血浆样品中的 SCFA。通过流式细胞术研究外周血单个核细胞。在招募时评估了性别、年龄、治疗、EDSS 和多发性硬化症严重程度评分 (MSSS)。结果 患者的血浆醋酸盐水平高于 HD (p = 0.003)。EDSS ≥ 5.0 的患者醋酸盐水平高于 EDSS ≤ 1.5 (p = 0.029) 和 HD (p = 2.97e-4) 的患者。醋酸盐水平与 EDSS (r = 0.387; p = 1.08e–4) 和 MSSS (r = 0.265; p = 0.011) 相关。在未经治疗的 MS 患者中,乙酸盐水平与 CD4+ 初始 T 细胞(r = - 0.550,p = 0.001)和直接与 CD8+ IL-17+ 细胞(r = 0.557;p = 0.001)呈负相关。结论 MS 患者的血浆醋酸盐水平高于 HD。在 MS 中,血浆乙酸盐水平、EDSS 和增加的 IL-17+ T 细胞之间存在相关性。未来的研究将阐明 SCFA 在该疾病中的作用。醋酸盐水平与 EDSS (r = 0.387; p = 1.08e–4) 和 MSSS (r = 0.265; p = 0.011) 相关。在未经治疗的 MS 患者中,乙酸盐水平与 CD4+ 初始 T 细胞(r = - 0.550,p = 0.001)和直接与 CD8+ IL-17+ 细胞(r = 0.557;p = 0.001)呈负相关。结论 MS 患者的血浆醋酸盐水平高于 HD。在 MS 中,血浆乙酸盐水平、EDSS 和增加的 IL-17+ T 细胞之间存在相关性。未来的研究将阐明 SCFA 在该疾病中的作用。醋酸盐水平与 EDSS (r = 0.387; p = 1.08e–4) 和 MSSS (r = 0.265; p = 0.011) 相关。在未经治疗的 MS 患者中,乙酸盐水平与 CD4+ 初始 T 细胞(r = - 0.550,p = 0.001)和直接与 CD8+ IL-17+ 细胞(r = 0.557;p = 0.001)呈负相关。结论 MS 患者的血浆醋酸盐水平高于 HD。在 MS 中,血浆乙酸盐水平、EDSS 和增加的 IL-17+ T 细胞之间存在相关性。未来的研究将阐明 SCFA 在该疾病中的作用。在 MS 中,血浆乙酸盐水平、EDSS 和增加的 IL-17+ T 细胞之间存在相关性。未来的研究将阐明 SCFA 在该疾病中的作用。在 MS 中,血浆乙酸盐水平、EDSS 和增加的 IL-17+ T 细胞之间存在相关性。未来的研究将阐明 SCFA 在该疾病中的作用。
