La description
Inclusion Criteria:
- SCD patient of all genotypes (SS, SC, S/β0 and S/β+)
- Age ≥ 18 years old
- Hospitalised for ACS (defined as the association of fever and/or acute respiratory symptoms with a new pulmonary infiltrate on chest imaging)
- Requiring supplemental O2 ≥ 2 L/min for SpO2 ≥ 95%
- Informed consent from the patient
- Affiliated to a social security regime
Exclusion Criteria:
- Patient having both ACS criteria and need for supplemental O2 ≥ 2 L/min for SpO2 ≥ 95% since more than 48 hours
- Requirement for home supplemental O2 or home CPAP / NIV.
- Signs of worsening respiratory failure mandating intubation (as defined in (Helms et al., 2024))
- Current enrolment in another interventional research concerning a respiratory support during ACS
- Known legal incapacity (patients under guardianship or curatorship)
- Exacerbation of asthma, chronic obstructive pulmonary disease or another known or suspected chronic respiratory disease
- Absolute contraindications to CPAP, including any of the following: patient not cooperating or opposing the technique, pneumothorax not drained, chest wound blowing, uncontrollable vomiting, upper gastrointestinal bleeding, craniofacial trauma, severe upper airway obstruction, traumatic tetraplegia at the initial phase, cardiac arrest, shock (need for vasopressor), or Coma Glasgow scale <12.
- Known pregnancy, breast feeding, women with childbearing potential will be tested for pregnancy and excluded if pregnant,

Intervention / Traitement |
|---|---|
|
Expérimental: O2+CPAP group
ACS episodes assigned to this group will receive supplemental O2 in addition to periods of CPAP.
|
ACS episodes assigned to this group will receive supplemental O2 in addition to periods of CPAP.
CPAP will target a positive pressure between 5 and 10 cmH2O.
CPAP will be given discontinuously (≥6 hours/day) based on patient tolerance .
CPAP sessions will be stopped when the patient achieves the criteria for cessation of supplemental O2.
These criteria will be the same as in the O2 group.
No sedation will be used for CPAP tolerance.
|
|
Aucune intervention: O2 group
ACS episodes assigned to the O2 group will receive supplemental O2 delivered through nasal cannula or high flow nasal cannula (for needs ≤6, and >6L/min, respectively) until endotracheal intubation, death, or fulfilment of O2 delivery cessation criteria (SpO2 ≥95% without supplemental O2).
SpO2 will be measured on room air, at least every 12 hours.

Description de la mesure |
Délai |
|---|---|---|
|
Time to résolution of acute chest syndrome (ACS)
Délai: Up to randomization
|
time to resolution of ACS, defined as the time from randomization to the joint resolution of fever (body temperature < 38°C), chest pain (visual analog scale, VAS ≤ 3 cm, morphine ≤ 40mg/24h), dyspnea (VAS ≤ 3 cm, respiratory rate < 25/min, no ventilatory support), and hypoxemia (SpO2 > 92% on room air) (Mekontso Dessap, Habibi, et al., 2025). If a VAS is unavailable, a verbal rating scale will be used. Resolution of ACS will be assessed every 8 to 12 hours and will be considered achieved if sustained across 2 to 3 consecutive evaluations (i.e., over a 24-hour period). |

Quality of life questionary
Délai: At inclusion, Day-28, and 3 months
|
EuroQol 5-Dimension 5-Level questionnaire (EQ-5D-5L) Index score.
The index score ranges from less than 0 (health states considered worse than death; country-specific minimum) to 1.0 (full health).
Higher scores indicate better health-related quality of life.tatus and monitor changes over time.
