Examine if the gut microbiota composition changes across repeated samples in paediatric-onset multiple sclerosis (MS) or monophasic-acquired demyelinating syndromes (monoADS).
A total of 36 individuals (18 MS/18 monoADS) with ⩾2 stool samples were included. Stool sample-derived DNA was sequenced. Alpha/beta diversities and genus-level taxa were analysed.
Mean ages at first sample procurement (MS/monoADS) = 18.0/13.8 years. Median time (months) between first/second samples = 11.2 and second/third = 10.3. Alpha/beta diversities did not differ between stool samples ( > 0.09), while one genus - did ( = 0.001).
The gut microbiota composition in paediatric-onset MS and monoADS exhibited stability, suggesting that single stool sample procurement is a reasonable first approach.
研究儿科发病的多发性硬化症（MS）或单相获得性脱髓鞘综合征（monoADS）患者的粪便样本中肠道微生物组成是否随重复样本发生变化。
共纳入 36 名个体（18 名 MS/18 名 monoADS，均有≥2 份粪便样本）。对粪便样本中的 DNA 进行测序。分析 alpha/beta 多样性和属水平分类群。
首次取样时的平均年龄（MS/monoADS）分别为 18.0/13.8 岁。首次/第二次取样之间的中位数时间（月）为 11.2，第二次/第三次为 10.3。粪便样本之间的 alpha/beta 多样性无差异（>0.09），但有一个属存在差异（=0.001）。
儿科发病的 MS 和 monoADS 患者的肠道微生物组成表现出稳定性，这表明单次粪便样本采集是一种合理的初步方法。
