E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The purpose of this study is to concurrently evaluate whether adjunct treatment with corticosteroids in children hospitalised with CAP is more effective in terms of the proportion of children reaching clinical stability and whether such adjunct treatment is no worse in terms of CAP relapse. The primary objective of this study therefore is to concurrently evaluate whether treatment of children hospitalised for CAP with oral betamethasone is superior to placebo in terms of time to clinical stability (defined as resolution of vital sign abnormalities in room air) after hospitalization: and whether inpatient treatment of childhood CAP with oral betamethasone is non-inferior to placebo in terms of the proportion of children with CAP-related readmission to hospital up to 28 days after randomisation. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives include the evaluation of effects of oral betamethasone treatment (versus placebo) in children hospitalised for CAP on: - duration of primary hospital stay; - severity and duration of CAP symptoms; - intensive care unit admissions; - mortality; - rate and severity of solicited clinical side effects; - rate of serious adverse events |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- At least 6 months of age and less than 14 years of age - Body weight between 5 kg and 45 kg - Admission to hospital (i.e. assignment of an inpatient case number or receipt of in-hospital treatment in a designated short stay unit) - Clinical diagnosis of CAP (see below) - Parent and/or child (as age-appropriate) willing to accept all possible randomised allocations and to be contacted by telephone weekly up to and including at 4 weeks after randomisation - Informed consent form for trial participation signed by parent The following constellation of signs and symptoms will be taken to indicate a clinical diagnosis of CAP: -Temperature >= 38°C measured by any method or history of fever in last 48 hours reported by parents AND at least two of the following signs and/or symptoms: - Presence of cough (observed or reported in last 72 to 96 hours); - Increased age-specific respiratory rate as defined by Paediatric Advanced Life Support (PALS) guidelines during assessment in PED (first or second triage or clinical examination); - Hypoxaemia <92% in room air as measured by transcutaneous oxygen monitoring; - Signs of laboured/ difficult breathing, including nasal flaring, chest retractions, grunting, abdominal breathing and shortness of breath; - Clinical signs of lobar pneumonia including focal dullness to percussion, focal reduced breath sounds, crackles with asymmetry. - Children younger than 6 month of age will not be included as a high proportion of acute lower respiratory tract infections affecting infants are episodes of bronchiolitis which are known not to benefit from corticosteroid treatment |
|
E.4 | Principal exclusion criteria |
- Presence of local complications (empyema, pleural effusion with clinically identified need for drainage, pneumothorax, and pulmonary abscess) - Chronic underlying disease associated with an increased risk of very severe CAP or CAP of unusual aetiology, such as sickle cell disease, primary or secondary immunodeficiency, chronic lung disease and cystic fibrosis - Bilateral wheezing without focal chest signs AND clinical indication for primary administration of steroids (most likely to represent respiratory tract infection affecting the medium airways, i.e. not pneumonia) - Admission to hospital with a primary clinical diagnosis of bronchiolitis - Inability to tolerate oral medication - Documented allergy or any other known contraindication to any trial medication - Subacute or chronic conditions requiring higher betamethasone equivalent or known primary or secondary adrenal insufficiency - Known diabetes mellitus (type 1) - Hospitalisation within the last two weeks preceding current admission with the possibility that pneumonia could be hospital-acquired or healthcare-associated - Completion of a course of systemic corticosteroids within 2 weeks from enrolment for courses of >5 days - Transfer for any reason to a non-participating hospital directly from the paediatric emergency department - Parents are unlikely to be able to reliably participate in telephone follow-up because of significant language barriers - Participation in another study with an investigational drug within the 30 days preceding and during the present study - Previous enrolment into the current study - Enrolment of the investigator, his/her family members, and other dependent persons. |

E.5 End points |
E.5.1 | Primary end point(s) |
Co-primary outcomes: (i) The time to clinical stability after randomisation in the active treated group (oral betamethasone for up to 2 days) as compared to the control group (placebo) will be one primary outcome. (ii) The proportion of children with CAP-related readmission within 28 days after randomisation comparing oral betamethasone and placebo will be the co-primary outcome.
Regarding (i): Clinical stability will be defined as the attending clinician assessing the child as being ready for hospital discharge or recorded normal respiratory rate, heart rate and oxygen saturation. Children discharged will be assumed to be clinically stable at discharge. For respiratory rate and heart rate, at least two consecutive age-related normal values as specified in the American Heart Association Accredited Pediatric Advance Life Support documentation will be taken to indicate stability. Oxygen saturation in room air of 92% or above will be considered normal.
Rationale: Clinical stability is relevant to patients and their families as a prerequisite for hospital discharge, and can have considerable socioeconomic impacts on the child and parents by allowing a return to normal activity for the whole family. A rapid recovery with no respiratory problems and no need for supplemental oxygen represents directly patient-relevant components of this outcome. The average length of stay (LOS) of hospitalised children with CAP is 2 days and by 3-4 days more than 75% of children with this diagnosis have been discharged home 35, 36. This reflects the relatively rapid recovery of children with CAP compared to adults. The outcome “length of stay” is expected to be closely correlated to the primary endpoint and will be assessed as a secondary endpoint. It has been discarded as a primary outcome as it is likely to vary locally and will be influenced by a range of administrative and other non-clinical factors. Nonetheless, a difference in time to stability is expected to be clinically and patient- relevant if it results in earlier discharge from hospital. Therefore, following a simulation study using a survey of admission and discharge times for CAP at the trial sites and time-to-stability data from an early subset of trial participants, a difference of 18 hours in median time to stability between the trial arms was selected as the threshold to allow postulation of a relevant effect.
Regarding (ii): CAP-related readmissions will be recorded by active surveillance at participating centres and in addition will be identified through parental reporting.
Rationale: In clinical practice, adjunct oral steroids are likely to be useful if the clinical benefits (higher likelihood of clinical stability at an early stage with the potential to be discharged from hospital earlier) outweigh any potential unwanted effects, such as clinically relevant CAP recurrence requiring readmission to hospital. Overall, a small increase in CAP recurrence may be acceptable assuming a low NNT for clinical stability. 28-day antibiotic retreatment rates for adults and children with lower respiratory tract infections prescribed antibiotics in the community setting have been described to be as high as 17% in the UK (Currie, 2014), but published Swiss hospital data for readmission rates are lacking. |
