概括

恩福图马布维多丁 (EV) 可以引起模仿严重疾病的皮肤反应. 细胞间IgG和活检上的"环状"线粒症有助于从类似的皮疹中识别EV诱导的皮肤毒性 (EVICT).

科学领域:

皮肤病理学皮肤病理学
皮肤瘤学皮肤瘤学
免疫组织化学免疫组织化学

背景情况:

恩福图马布维多丁 (EV) 治疗与频繁的皮肤喷发有关.
这些喷发在临床上可能类似于多形红疹和史蒂文斯-约翰逊综合征/有毒表皮解 (SJS/TEN).
将EV诱导的皮肤毒性 (EVICT) 与这些模仿物区分开来,对于患者管理至关重要.

研究的目的:

为了定义EVICT的临床病理学模式.
为了确定区分EVICT与SJS/TEN和多形红斑的免疫组织化学标志物.

主要方法:

对19名接受EV治疗的患者和10名多型红血瘤或SJS/TEN的对照患者的回顾性分析.
对评估组织学模式的活检进行盲目审查.
针对免疫球蛋白G (IgG),Nektin-4和细胞毒性T细胞的免疫组织化学.

主要成果:

在EV病例中观察到四种不同的接口皮肤炎模式.
皮肤上"环"线粒症在EV活检中频繁出现,在对照组中没有出现.
细胞间IgG染色显示高灵敏度 (82%) 和特异性 (80-100%) 对EVICT.

结论:

细胞间IgG和"环状"线粒分裂是EVICT的宝贵诊断标记.
这些发现有助于区分与EV相关的喷发与多形红斑和SJS/TEN.
常规免疫组织化学提供了一个实用的诊断框架.

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Drug Toxicity: Allergic Reactions

Drug Toxicity: Allergic Reactions

Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...
