肌缩性侧面硬化症 (ALS) 患者的2型糖尿病 (T2DM) 与更严重的呼吸系统问题和晚期发病年龄有关. 这种并发症也可能与C9ORF72基因扩张的较低患病率有关.
科学领域:
- 神经学 神经学
- 内分泌学 在内分泌学.
- 遗传学 遗传学 是一个
背景情况:
- 2型糖尿病 (T2DM) 是肌缩侧面硬化症 (ALS) 的常见并发症.
- 对T2DM对ALS进展和临床表现的影响需要进一步研究.
研究的目的:
- 在一个大型的ALS队列中调查T2DM的流行率和临床特征.
- 探索T2DM与ALS患者疾病严重程度,呼吸功能和遗传因素之间的关联.
主要方法:
- 使用意大利埃米利亚罗马尼亚地区ALS登记处数据进行的回顾性队列研究 (2009-2021年).
- 对1756名ALS患者的分析,将T2DM (diALS) 患者与没有 (ndALS) 患者进行比较.
- 临床参数的评估,呼吸功能 (强迫生命能力,非侵入性通风使用) 和遗传检测 (C9ORF72).
主要成果:
- 与ndALS相比,T2DM患者 (diALS) 年龄较大,BMI较高,在诊断时体重减轻较大.
- diALS显示出更高的呼吸开始频率和表型,更低的强迫生命能力,以及增加的非侵入性通风使用.
- 在diALS组中,C9ORF72基因扩展显著不足 (0%与ndALS中的7.64%相比).
结论:
- 在ALS中T2DM与更严重的呼吸功能障碍有关,可能表明特定的呼吸道肌肉脆弱.
- 在diALS的临床特征与文献一致,包括晚期发病.
- 在diALS中C9ORF72扩张的降低患病率表明它可能在新陈代谢和炎症中起作用,因此需要进一步研究非遗传因素.

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
