概括
在多发性硬化症 (MS) 中,不依赖复发活动 (PIRA) 的进展与视网膜缩有关. 这项研究表明,视网膜层稀薄与不依赖复发和MRI活动 (PIRMA) 的进展相关,这表明它反映了超出炎症的神经轴损伤.
科学领域:
- 神经科学是一个神经科学.
- 眼科医生 眼科 眼科
- 临床神经学 临床神经学
背景情况:
- 独立于复发活动的进展 (PIRA) 导致复发性多发性硬化症 (RMS) 的残疾.
- 通过光学连贯断层扫描 (OCT) 的视网膜层缩表明神经轴损伤,与PIRA相关.
- 视网膜缩和PIRA的炎症驱动因素与真正的进展之间的联系仍然不清楚.
研究的目的:
- 调查视网膜层缩和不依赖复发和MRI活动 (PIRMA) 的进展之间的关系.
- 为了澄清视网膜缩是否反映出亚临床炎症或MS的真实进展.
- 评估视网膜层薄化作为MS中神经轴突退化的潜在生物标志物.
主要方法:
- 在开始疾病修饰治疗 (DMT) 后,对210名RMS患者进行序列性OCT扫描的前性观察研究.
- 根据复发和MRI活动确定PIRA和PIRMA的复合措施定义的残疾累积.
- 多变量混合效应模型评估了PIRMA与外皮毛状视网膜神经纤维层 (pRNFL) 和黄斑结节细胞加上内状层 (GCIPL) 稀薄之间的关联.
主要成果:
- 在13.3%的患者中发现了PIRMA,占PIRA病例的54.1%.
- 皮尔马与GCIPL (每年0.72%) 和PRNFL (每年1.05%) 的加快稀释显著相关.
- 这些关联在调整年龄,性别,疾病持续时间,基线视网膜厚度和DMT疗效后仍然显著.
结论:
- 在RMS患者中,视网膜缩与PIRMA显著相关.
- 这些发现支持视网膜层薄化作为MS中神经轴突退化的生物标志物,独立于急性焦点炎症.
- 通过OCT测量的视网膜缩可能有助于区分MS的炎症和非炎症进展.

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
