Analysis of the Dynamics of the Lung Microbiota During Acute Exacerbation of COPD Requiring Admission to Intensive Care Unit (ADMiRE)
Analysis of the Dynamics of the Lung Microbiota During Acute Exacerbation of COPD Requiring Admission to Intensive Care
調査の概要
詳細な説明
Chronic obstructive pulmonary disease (COPD) is a frequent cause of ICU admission. COPD exacerbations are a leading cause of lung function worsening and of morbimortality. Hospitalizations due to COPD exacerbations are highly expensive for health insurance system. Bacterial pulmonary microbiota has been shown to be correlated to the severity of COPD and to exacerbations. Nevertheless fungi and viruses which are full actors of pulmonary microbiota have not yet been investigated.
Our primary outcome will be the assessment of alpha and beta diversity dynamics of the whole pulmonary microbiota (bacteria, fungi and viruses) between COPD exacerbation and steady state.
This study will prospectively include 24 patients at ICU admission for COPD exacerbation with sputum sampling. Steady-state as defined during a 2 months-later visit will be studied with another sputum collection.

説明
Inclusion Criteria:
- Patient above 18 admitted in ICU
- Admitted for COPD exacerbation defined by sustained (> 2 days) worsening of respiratory symptoms considering Anthonisen's criteria with life-threatening condition.
- Needing mechanical ventilation (noninvasive ventilation or oro-tracheal intubation)
- COPD condition will be presumed according to patient's respiratory history or previous lung function testing
- Able to consent or with the patient's family consent
- Affiliated to a social insurance scheme
No inclusion Criteria:
- COPD patient admitted for another cause than respiratory failure
- person under tutorship or curatorship
- living further than 100 kilometers away from the ICU
- expected survival inferior to 1 week
Exclusion Criteria
- Lung function testing not consistent with COPD at steady-state visit
