呼吸道疾病如喘和支气管切除症 (包括过敏性支气管肺性阿斯伯吉洛症 (ABO)) 中的微生物群和代谢组概况可以预测恶化的风险并指导个性化治疗策略.
科学领域:
- 呼吸系统医学 呼吸系统医学
- 微生物组研究 微生物组研究
- 代谢学 代谢学 代谢学
背景情况:
- 呼吸道疾病,如喘和支气管切除,共享重叠的症状和病理生理学.
- 过敏性支气管肺性阿斯伯吉洛症 (ABO) 是一种复杂的炎症状况,经常与喘并存.
- 了解宿主,微生物群和代谢组之间的相互作用对于疾病管理至关重要.
研究的目的:
- 为了比较有过敏性支气管肺性阿斯伯吉洛症 (ABO),支气管切开症和喘患者的唾液微生物群和代谢组.
- 为了将这些概况与临床特征,炎症内型和恶化风险相关联.
- 确定潜在的生物标志物,以个性化管理ABO.
主要方法:
- 一项前性队列研究,涉及247名患者 (99名ABO患者,61名喘患者,87名支气管病患者).
- 唾液分析包括差异细胞计数,微生物群的16SrRNA基因测序,以及代谢组的液体染色学/质谱学.
- 香农-维纳多样性指数 (SWDI) 评估了微生物失生症;对患者进行了加剧的跟踪.
主要成果:
- 在喘,ABO和支气管切除症之间,以及在eosinophilic和non-eosinophilic ABO之间,观察到微生物群和代谢物概况的明显差异.
- Pseudomonadaceae 和 Rothia 是 ABO 的关键区分因素.
- 特定的SWDI和eosinophilia组合预测了ABO患者第一次恶化的时间较短.
结论:
- 整合微生物群,新陈代谢和埃索诺菲尔炎症数据可以更好地预测ABO恶化风险.
- 这种多组合的方法支持个性化的管理策略,为患者的 ABO 和相关的呼吸道疾病.

Gram Stain
The Gram Stain is an integral part of sputum studies. It involves the staining of sputum, which permits...
Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
Asthma: Pathogenesis and Management
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.
