Exclusion criteria
Exclusion criteria: Non-Inclusion criteria before HSCT : Patients with no affiliation to a social security scheme (beneficiary or legal) Pregnancy Asthma defined by reversibility with salbutamol (FEV1 > 12% or FEV1> 200ml) under inhaled corticosteroids or long acting beta agonists during the last three months Non-Randomisation criteria : - Viral respiratory infection (fever = 38°C, tachypnea according to age, positive viral PCR pharyngeal aspiration) during the last month; - Lower respiratory tract infection (fever = 38°C, tachypnea, radiologicaly or echography confirmed pneumonia, sputum) during the last month; - Invasive fungal disease (as defined by EORTC/MSG consensus group) during the last month. - Potent cytochrome P450 3A4 inhibitors, such as ritonavir, ketoconazole, itraconazole, troleandomycin, clarithromycin, nelfinavir, nilfinavir and nefazodone. - Corticosteroids or bronchodilatators inhaled treatment after transplantation - BOS
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To assess the effect of a Fluticasone Propionate associated with Salmeterol using inhalation chamber compared to placebo on respiratory function at 6 months in children over six years of age who underwent allogeneic hematopoietic stem cell transplantation with a decline of FEV1 = 10% from pre transplantation during the first year after transplantation. ;Secondary Objective: To assess the effect of a Fluticasone Propionate associated with Salmeterol using inhalation chamber compared to placebo in children over six years old underwent allogeneic hematopoietic stem cell transplantation with a decline of FEV1 = 10% from pre transplantation to 6 months following the initiation of the treatment on pulmonary function, respiratory symptoms, Bonchiolitis Obliterative Syndrome (BOS) rate, oral steroid exposure and the occurrence of infections.;Primary end point(s): The primary criterion will be the difference in the FEV1% predicted value from inclusion to 6 months following the initiation of treatment. ;Timepoint(s) of evaluation of this end point: 6 Months | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1)Endpoints relative to respiratory symptoms : * dyspnea will be evaluate at the NYHA scoring; * step test (patient climb up and down step during three minutes at the frequency of 30/mn) : Respiratory rate, dyspnea Heart rate, SaO2 during the exercise. 2) Endpoints relative to pulmonary function : * FEV1 (Forced expiratoy volume) VC (Vital Capacity) , TLC (Total Lung capacity) , RV (Residual volume), FRC (Functional Residual Capacity), sRaw (specific airway resistance) DLCO (diffusing capacity of the lungs) using a similar method of measurement for static lung volumes (plethysmography) * Number of patients presented with BOS defined as the absence of infection, and FEV1 120% or air trapping or bronchiectasies or small airways thyckening on computed tomography 3) Endpoints relative to GVHD : * Acute and Chronic GVHD manifestations defined on NIH consensus with scoring; * First line of treatment: cumulative dose of corticosteroid systemic exposure and cumulative dose of calcineurins inhibitors. * Second line of GVHD treatment exposure will be assed using the other type of treatment. 4) Endpoints relative to respiratory infections : - Number of adverse events. 5) Endpoints relative to safety and tolerance: - Adverse events during the study period such as treatment tolerance, thrush, death. ;Timepoint(s) of evaluation of this end point: 12 Months | — |
