Respiratory Syncytial Virus Infection in Exacerbations of Chronic Obstructive Pulmonary Diasease: the RECODE Study

Not yet recruiting

• Conditions: Respiratory Synctial Virus; COPD; Chronic Obstructive Pulmonary Disease (COPD); Exacerbation of COPD

• Registration Number: NCT06735612
• Lead Sponsor: Fundacio Privada Mon Clinic Barcelona

Brief Summary

The goal of this observational study is to determine the prevalence of respiratory syncytial virus (RSV) infection and evaluate its association with clinical outcomes in patients with chronic obstructive pulmonary disease (COPD) who experience exacerbations during the RSV season (October-April). The main question it aims to answer is:

* What is the prevalence of RSV infection in patients with COPD during exacerbations in the RSV season?

* Does RSV infection lead to worse clinical outcomes, including hospitalization, longer length of stay, acute cardiovascular events, and/or death in patients with COPD exacerbations?

Researchers will compare patients with RSV infection to those without RSV infection to see if RSV infection results in worse clinical outcomes, such as increased hospitalization, longer stays, cardiovascular events, or death.

Participants will:

* Be adults diagnosed with COPD who present to the emergency department or day hospital due to acute exacerbations of their respiratory symptoms.

* Receive treatment as per standard clinical care for COPD exacerbations, including long-acting bronchodilators and inhaled corticosteroids, and may complete a course of antibiotics and/or oral corticosteroids if prescribed during hospitalization.

* Undergo diagnostic testing for RSV infection as part of the clinical routine to determine the presence or absence of the virus during their exacerbation.

* Have clinical outcomes monitored, including hospitalization rate, length of stay, and any acute cardiovascular events, as well as mortality during the exacerbation period.

* Provide relevant demographic and clinical data, including medical history, COPD severity, comorbidities, and previous exacerbation events.
