概括

在阿司匹林加剧的呼吸道疾病 (AERD) 中,已经确定了不同的代谢. 较高的血15-oxo-ETE水平与AERD患者更严重的喘和较差的控制相关.

科学领域:

生物化学生化学
免疫学免疫学免疫学
呼吸系统医学呼吸系统医学

背景情况:

在阿司匹林加重的呼吸道疾病 (AERD) 中,阿拉基酸代谢的调节失调,有助于炎症和抗炎症eicosanoids的失衡.
这项研究研究了AERD.中的15-LOX-1和5-LOX通路的终端代谢物.

研究的目的:

根据15-oxo-eicosatetraenoic acid (15-oxo-ETE) 和5-oxo-eicosatetraenoic acid的血和尿液水平来确定代谢.
为了分析这些与其他氧化酶阿拉基酸代谢产物和临床变量一起.

主要方法:

对78名AERD患者和63名阿司匹林耐受性喘 (ATA) 患者进行了分层集群分析.
数据包括人口统计学,临床,生化,治疗变量,鼻腔CT发现,以及HPLC-MS/MS测量的eicosanoid水平.

主要成果:

在AERD和ATA组中发现了两种不同的内分类型 (集群).
与ATA相比,AERD集群显示了较高的隆德-麦凯分数和尿液中的白血素E4,但尿液中的15-oxo-ETE较低.
集群1 (AERD和ATA) 的患者年龄较大,BMI较高,喘更严重,控制较差,血中15-基酸酸,15-oxo-ETE和5-基酸酸酸的含量较高.

结论:

较高的血和较低的尿15-oxo-ETE水平与AERD患者的更严重的喘和更糟糕的喘控制有关.
这些发现与AERD患者的年龄较大和更高的体重指数有关.

关键词:

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
