Allergic Drug Reactions

972
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Hypersensitivities

1.0K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Asthma: Pathogenesis and Management

576
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Asthma-II: Pathophysiology and Classification

2.8K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

科学领域:

  • 免疫学
  • 过敏症
  • 临床医学

背景情况:

  • 异常性过敏症 (IA) 呈现为重复性,危及生命的过敏反应,缺乏可识别的触发因素,造成重大诊断和治疗挑战.
  • 艾滋病需要全面的差异诊断,包括IgE介导过敏,辅因子依赖性过敏症,巨细胞疾病和全身模仿症.
  • 目前的治疗通常涉及预防性抗组胺剂和皮质类固醇,新出现的证据支持抗IgE治疗耐火病例.

研究的目的:

  • 描述一个17岁女性的异常过敏症病例.
  • 审查诊断工作和治疗异常性过敏症的策略.
  • 强调在IA诊断中排除其他疾病的重要性.

主要方法:

  • 一个17岁的女性病例报告,
  • 诊断评估包括血清三酶水平,皮肤刺伤测试,α- gal IgE测试和KIT突变分析.
  • 治疗包括预防性 cetirizine,症状消失,没有进一步的反应.

主要成果:

  • 患者经历了反复出现的发红,和呼吸症状,但没有可识别的触发因素.
  • 观察到急性血清酸酶水平升高,基线水平正常,过敏测试呈阴性.
  • 每天服用 cetirizine 的预防措施有效地预防了进一步的过敏反应.

结论:

  • 固态过敏仍然是一个排除的诊断, 需要彻底的调查来排除其他原因.
  • 这一案例证明了抗组胺预防治疗IA的潜在有效性.
  • 进一步的研究对于标准化诊断途径和优化AI的长期治疗策略至关重要.
