概括
这项研究表明,dupilumab在三年内为患有中度至重度亚托皮炎 (AD) 的日本患者提供了持续的有效性和安全性. 长期使用dupilumab显著改善了湿疹区域和严重性指数得分,并减少了关键炎症标志物.
科学领域:
- 皮肤病学 皮肤病学
- 免疫学 免疫学 免疫学
- 药理学 药理学是指药理学的学科.
背景情况:
- 杜皮卢马布是一种抗联素-4受体α抗体,于2018年在日本获得治疗中度至重度亚托皮炎 (AD) 的批准.
- 虽然存在短期真实世界的数据,但杜皮卢马布在阿兹海默症患者的长期有效性和安全性数据仍然有限.
- 这项研究解决了对日本患者队列中dupilumab影响的综合长期数据的需求.
研究的目的:
- 追溯调查dupilumab在日本中度至重度AD患者的长期 (3年) 疗效和安全性.
- 评估临床严重程度尺度,患者报告的结果和相关实验室标记的变化.
- 评估与长期杜皮卢马布治疗相关的不良事件的发生率和性质.
主要方法:
- 对60名日本成人中度至重度阿尔茨海默病患者的回顾性分析,这些患者在3年以上的时间里接受了dupilumab治疗.
- 收集的数据包括临床严重性得分 (IGA,EASI,BSA) 和患者报告的结果 (DLQI,POEM,VAS).
- 分析了胸腺和激活调节的化学激素 (TARC),免疫球蛋白E (IgE),乳酸脱酶 (LDH),以及循环中的中性粒细胞和乙氨基粒细胞的血清水平.
主要成果:
- 在IGA,EASI,BSA,DLQI,POEM和VAS的3个月后观察到显著改善,持续了3年.
- 湿疹区域和严重性指数 (EASI) 评分在第三年下降了高达90.0%.
- 血清TARC,IgE和LDH水平在第3年显著下降. 中性粒细胞数量略有下降,而乙氨基细胞数量在第二年和第三年显著下降. 眼部疾病是最常见的不良事件 (38.3%).
结论:
- 杜皮卢马布在日本患者中显示持续的临床有效性和可容忍的安全性,患者在使用3年后患有中度至重度的亚托皮性皮肤炎.
- 长期的杜皮卢马布治疗与关键炎症生物标志物的显著减少有关,包括TARC,IgE和异osinophils.
- 这些发现支持继续使用dupilumab来管理中度至重度的AD,强调其长期益处和可管理的安全性.

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
755
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...
