研究设计:

Study design:

Cross-sectional 

研究目的:

(1)分析HPH(COPD-PH)患者肠道菌群的结构变化以及低氧对肠道菌群功能的影响,并鉴定血浆代谢物特征。 (2)探讨肠道菌群失调引起的代谢重编程与肺血管重塑指标(如PAP、PVR、PCWP等)的相关性,为HPH的发病机制提供新的理论依据。  

Objectives of Study:

(1) Analyse structural alterations in the gut microbiota of patients with HPH (COPD-PH) and investigate the impact of hypoxia on gut microbiota function, whilst identifying plasma metabolite signatures. (2) Examine the correlation between metabolic reprogramming induced by gut dysbiosis and pulmonary vascular remodelling markers (such as PAP, PVR, PCWP, etc.), thereby providing novel theoretical insights into the pathogenesis of HPH.

纳入标准:

1. 参照《2022 ESC/ERS 肺动脉高压诊疗指南》(满足毛细血管前肺动脉高压的诊断标准:海平面、静息状态下右心导管测量肺动脉平均压(Mean Pulmonary Arterial Pressure ,mPAP)>20mmHg ,同时肺小动脉楔压<15mmHg 、肺血管阻力(Pulmonary Vascular Resistance ,PVR)>3 Wood Units); 2. 符合 2025COLD 指南 COPD 诊断标准; 3. 年龄≥18 周岁; 4. 健康对照组纳入生活习惯相似的健康人(本研究中健康对照优先选择与COPD-PH 患者生活习惯高度一致的家属),同时由内科医师根据临床表现和体征,或者根据近期检查排除肺动脉高压和器质性疾病。

Inclusion criteria

1.With reference to the <2022 ESC/ERS Guidelines for the Diagnosis and Treatment of Pulmonary Hypertension> (meeting the diagnostic criteria for pre-capillary pulmonary hypertension: at sea level and in a resting state, the mean pulmonary arterial pressure (mPAP) measured by right heart catheterization is >20 mmHg, while the pulmonary capillary wedge pressure is <15 mmHg and the pulmonary vascular resistance (PVR) is >3 Wood Units); 2.Meeting the diagnostic criteria for COPD specified in the 2025 COLD Guidelines; 3.Aged >=18 years old; 4. Healthy controls include healthy individuals with similar living habits (in this study, healthy controls are preferred to be family members of COPD-PH patients with highly consistent living habits). Meanwhile, internal medicine physicians exclude pulmonary hypertension and organic diseases based on clinical manifestations, signs, or recent examinations.

排除标准:

1.用药情况:在入组前 4 周内使用抗感染药物包括抗真菌、抗生素、抗病毒药物、抗寄生虫药物;使用免疫抑制药物;以治疗或保健为目的使用以益生菌为主要成分的药物或保健品(不包括发酵食品); 2. 存在 1 个月以上的过量饮酒(每日酒精摄入量超过 50g); 3.其它疾病史包括感染性疾病、胃肠道疾病、自身免疫性疾病、结缔组织病、肝脏和肾脏疾病、内分泌系统疾病以及血液系统疾病等; 4.在 2 年内有过手术史; 5.身体质量指数(Body Mass Index ,BMI)≥32 或≤18.5; 6.在采样期处于中、重度急性疾病状态。

Exclusion criteria:

1. Medication use: Use of anti-infective drugs (including antifungal, antibiotic, antiviral, and antiparasitic drugs) within 4 weeks before enrollment; use of immunosuppressive drugs; use of drugs or health products with probiotics as the main component for therapeutic or health-care purposes (excluding fermented foods); 2. Excessive drinking for more than 1 month (daily alcohol intake exceeding 50g); 3. Other medical histories, including infectious diseases, gastrointestinal diseases, autoimmune diseases, connective tissue diseases, liver and kidney diseases, endocrine system diseases, and hematological system diseases, etc.; 4. Having a surgical history within 2 years; 5.Body Mass Index (BMI) >=32 or <=18.5; 6.Being in a moderate or severe acute disease state during the sampling period.
