概括
严重喘患者呈现较高的IL-17水平和阳性自身血清皮肤测试 (ASST),表明潜在的自身免疫联系. 这表明IL-35可能在严重病例中控制炎症的作用降低.
科学领域:
- 免疫学 免疫学 免疫学
- 呼吸系统医学 呼吸系统医学
- 喘的发病原因
背景情况:
- 严重的喘表现出治疗反应和控制不佳,需要对新型病原遗传机制进行研究.
- 干白素-35 (IL-35) 可能通过抑制促炎性干白素-17 (IL-17) 来保护自身免疫性疾病.
- 自体血清皮肤检测 (ASST) 是一种经过验证的自免疫抗体查工具.
研究的目的:
- 研究IL-35和IL-17在严重喘中的作用.
- 为了比较ASST阳性,呼出的氧化 (FeNO) 和轻度至中度和重度喘患者之间的亚托皮状态.
- 为了探索严重喘中潜在的自身免疫病原性.
主要方法:
- 招募了患有轻度至中度和重度喘的患者.
- 分析了临床数据,包括吸烟史,家族史,过敏性鼻炎,过敏原特异性IgE和FeNO.
- 使用ELISA测量了血清IL-35和IL-17水平,并评估了ASST结果.
主要成果:
- 与轻度至中度喘患者相比,严重喘患者的吸烟史,家族史和阳性ASST的比率更高.
- 在严重喘中,血清IL-17水平显著升高,而IL-35水平没有显著差异.
- 阳性ASST结果与严重喘风险增加相关 (OR=5.277),而过敏原阳性降低了这种风险 (OR=0.123).
结论:
- 在严重喘中,高IL-17和高ASST阳性表明潜在的自身免疫成分.
- 在严重的喘中,IL-35似乎对IL-17的抑制作用减弱.
- 这些发现凸显了在严重喘的发病过程中需要考虑自身免疫机制的必要性.

Asthma: Pathogenesis and Management
411
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
2.7K
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:

Asthma-I: Introduction
2.6K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Autoimmune Disorders
447
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.
