E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine if the systemic administration of corticosteroids, as compared to placebo, increases the number of ventilator-free days (VFD) and alive at day 28 in COPD patients admitted to an ICU, a step-up unit or a respiratory care unit for an ACRF requiring ventilatory support, either invasive or non-invasive. |
Déterminer si l’administration d’une corticothérapie systémique, comparée au placebo, augmente le nombre de jours vivant et sans assistance ventilatoire à J28 chez les patients atteints de BPCO admis en Réanimation pour une exacerbation aiguë sévère nécessitant une assistance ventilatoire, invasive ou non-invasive. |
|
E.2.2 | Secondary objectives of the trial |
Evaluate the effect of corticosteroids administration, as compared to placebo on :
- mechanical ventilation and support
- side effects of corticosteroids
- lenght of stay
- mortality
- COPD exacerbations case
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1) Patients aged ≥ 40 years, man or woman
2) Strongly suspected or documented COPD defined by all the following criterias :
- Persistent respiratory symptoms (dyspnoea, chronic cough or sputum production)
- History of exposure to a risk factor such as tobacco smoke
- If available, pulmonary function tests showing airflow limitation that is not fully reversible (post-bronchodilator ratio of forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) ratio < 0.7)
3) ACRF, defined by the presence of the two following criteria:
- COPD exacerbation defined by a change in the patient baseline respiratory symptoms: dyspnoea, cough or sputum (volume or purulence) for at least 24 hours and requiring a change in regular respiratory medication
- Acute respiratory failure (defined by clinical signs of excessive muscle activity: polypnea ≥ 30 breaths /min or use of accessory respiratory muscles) requiring ventilatory support, either invasive (implemented because of respiratory distress) or NIV (implemented because of hypercapnic acidosis with PaCO2 ≥ 45 mmHg and pH ≤ 7.35)
- Acute respiratory failure < 24h
4) Admission to an ICU, a step-up unit or a respiratory care unit
5) Written Informed consent from the patient or his surrogates. In patients who are not able to consent on admission (i.e., because of hypercapnic encephalopathy) and in absence of a substitute decision maker, an emergency inclusion procedure will be allowed, with a mandatory delayed consent
6) Affiliation to (or benefit from) French health insurance system.

1) Âge ≥ 40 ans
2) BPCO documentée ou fortement suspectée définie par tous les critères suivants :
-Symptômes respiratoires chroniques (dyspnée, toux ou expectorations)
-Exposition à un facteur de risque tel que la fumée de tabac
-Si disponible, EFR montrant un syndrome obstructif non ou partiellement réversible (rapport post-bronchodilatateur VEMS/ CV < 0.7)
3) Exacerbation aiguë sévère, définie par la présence des 2 critères suivants :
- Exacerbation de BPCO définie par une aggravation des symptômes habituels du patient, pendant au moins 24h et nécessitant une intensification du traitement médical
- Détresse respiratoire aiguë (polypnée ≥ 30 cycles.min-1 ou l’utilisation des muscles respiratoires accessoires) nécessitant un support ventilatoire, invasif (introduit en raison de la détresse respiratoire) ou non-invasif (introduit en raison d’une acidose hypercapnique avec PaCO2 ≥ 45 mmHg et pH ≤ 7.35).
4) Admission en Réanimation, Unité de Surveillance Continue ou Unité de Soins Intensifs
5) Consentement de participation du patient ou d’un proche. Si le patient n’est pas capable de donner son consentement et si aucun proche n’est présent, une procédure d’inclusion en urgence est possible. Dans ce dernier cas, un consentement de poursuite est nécessaire.
6) Affiliation au système de soin/sécurité sociale |
|
E.4 | Principal exclusion criteria |

1) Previous diagnostic of asthma, according to “GINA” international guidelines

3) Contra-indication of systemic corticosteroids treatment: allergy to corticosteroids, uncontrolled severe arterial hypertension, uncontrolled diabetes mellitus, gastro-intestinal ulcer bleeding
4) Pneumothorax at randomization
5) Extracorporeal life support (ECMO or ECCO2R) at randomization
6) Moribund patient life expectancy < 3 months
7) Pregnancy
8) Patients protected by law
9) Exclusion period due to other clinical trial enrolment which can influence primary outcome
10) Previous inclusion in the present study.
