概括
托西利祖马布 (TCZ) 有效地减少了患有髓寡细胞糖蛋白IgG相关视神经炎 (MOG-ON) 的患者的复发,这些患者以前未能接受其他治疗. 该疗法显著改善了视力,并且耐受性良好,支持其用于耐火MOG-ON的治疗.
科学领域:
- 神经眼科神经眼科
- 免疫学 免疫学 免疫学
- 临床神经学 临床神经学
背景情况:
- 在预防复发发作和严重视力丧失方面,氨酸寡干细胞糖蛋白IgG相关的视神经炎 (MOG-ON) 提出了挑战.
- 作为一种IL-6受体抑制剂的托西利祖马布 (TCZ) 正在作为耐火性MOG-ON.ON的潜在治疗方法进行研究.
- 在神经眼科中,预防MOG-ON复发仍然是一个至关重要的未满足的需求.
研究的目的:
- 为了评估托西利祖马布 (TCZ) 的疗效和安全性,在患有复发性MOG-ON的患者中.
- 评估TCZ对MOG-ON患者每年复发率 (ARR) 和最佳校正视敏度 (BCVA) 的影响.
- 确定TCZ在一组对先前疗法耐药的MOG-ON患者中的安全概况.
主要方法:
- 进行了一项开放式单臂临床试验,涉及复发MOG-ON的患者.
- 参与者接受了托西利祖马布 (TCZ) 作为单一疗法或附加疗法至少12个月.
- 关键的结果措施包括年度复发率 (ARR),最佳校正视力敏度 (BCVA) 和不良事件.
主要成果:
- 在TCZ治疗期间,10名患者中有7名 (70%) 没有复发.
- 年复发率 (ARR) 的中位数显著下降,从1.9降至0.0 (p=0.006).
- 中位数最佳校正视敏度 (BCVA) 从2.7 logMAR提高到0.2 logMAR,仅报告了轻微的不良事件.
结论:
- 托西利祖马布 (TCZ) 治疗在减少MOG-ON患者复发方面表现出显著的疗效.
- TCZ是MOG-ON的安全和有效的治疗选择,特别是在对其他免疫疗法耐药的情况下.
- 这些发现支持使用TCZ,与或没有其他免疫抑制剂,以管理难以治疗的MOG-ON.

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
115
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Open Angle Glaucoma: Treatment
391
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
