Impact of Eradication Therapy on Helicobacter Pylori Infection With Chronic Obstructive Pulmonary Disease:

Recruiting now · Phase 1

Conditions studied: Chronic Obstructive Pulmonary Disease (COPD), With Poitive H Pylori

In brief

Helicobacter pylori (HP) is a well-established pathogen responsible for chronic gastritis and peptic ulcer disease. Its presence has been implicated in the development of gastric malignancies such as adenocarcinoma and mucosa-associated lymphoid tissue lymphoma. Chronic H. pylori infection is associated with systemic inflammatory responses and various extra gastric diseases, including cardiovascular, metabolic, and neurological disorders. Furthermore, H. pylori infection contributes to gastrointestinal dysbiosis by interacting with gastrointestinal microbiota, which may be involved in gastric carcinogenesis and other systemic disorders. Growing evidence highlights the role of dysbiosis in chronic respiratory diseases, such as chronic obstructive pulmonary disease (COPD) and asthma. Emerging epidemiological evidence suggests a potential association between H. pylori infection and respiratory diseases, including COPD. Several observational studies and meta-analyses have found that H. pylori infection in patients with COPD may be associated with systemic inflammatory markers and altered pulmonary function parameters. Despite these associations, the causal mechanisms underlying this relationship remain unclear. Furthermore, it is uncertain whether eradication of H. pylori yields measurable benefits on clinical outcomes in COPD patients. So, Our aim to evaluate changes in symptoms, pulmonary function, and inflammatory markers after H. pylori eradication therapy in the H. pylori-positive COPD patients. an intervention study (quasi experimental), study will be carried out in the inpatient and outpatient clinics of Chest Department, Faculty of Medicine, Zagazig University hospitals. Patients included in the study: well controlled COPD patients attending outpatient clinics for a period of 6 months fulfilling inclusion and exclusion criteria will be included in this study.
