"Palivizumab Therapy for RSV-bronchiolitis"
There is a growing body of literature suggesting that monoclonal antibody could be efficacious in infants with RSV-bronchiolitis, well tolerated with no or clinically insignificant adverse effects.
"The investigators hypothesize that a single dose of iv palivizumab 15 mg/kg in diagnosed infants <3 months old with RSV bronchiolitis will result in fewer infants with readmissions to infirmary/observation or hospital for relapse during 3 weeks of follow-up after discharge".

The study will be conducted between September 2014 and April 2018 in the short stay unit of the Pediatric Emergency Center (PEC) of Hamad General Hospital, the only pediatric emergency facility in the State of Qatar. The PEC serves an average of 280 000 patients annually and manages 42 beds in a short stay infirmary unit, to which patients are admitted if they are too ill to be sent home but do not need the intensive care unit. Patients admitted to the unit are assessed at least every 6 hours by a pediatrician to determine readiness for discharge. The length of stay in the unit for bronchiolitis ranges from 6 to 168 hours. In 2012, the investigators saw 8718 infants and young children in 10 666 visits for bronchiolitis. Infants aged ≤3 months presenting to the unit for treatment of viral bronchiolitis will be eligible for the study. Consecutive patients will be recruited except when a study nurse is unavailable or the unit is too busy to recruit.
Patients will be examined on presentation, and those needing additional treatment or observation will be admitted to the short stay infirmary unit. Consecutive patients with bronchiolitis will be assessed for study eligibility within 2 hours. Eligible patients will be enrolled after obtaining written consent. For those who consent, plain chest radiography, and nasopharyngeal swabs will be taken for RSV detection. If the patient has a positive RSV rapid antigen test, patients will be randomized to receive one of the study arms. Bronchiolitis severity score will be measured initially at the start of treatment and then at 12-hour, 24-hour, 36-hour and 48-hour thereafter. The medical team in addition to the parents and patients will be blinded to the medication delivered. Adverse effects in each group will be carefully monitored and documented. Patients will be sent home with salbutamol metered-dose inhalers with an appropriately sized Aerochamber with mask attachment. Daily follow-up by study nurse by telephone is mandatory for 1 week after discharge and then once a week for 2 weeks thereafter. The patient could return to the pediatric emergency center earlier if needed. At all revisits for the same illness, nasopharyngeal swabs will be taken for RSV rapid antigen test and the result recorded.
- Active arm: A single dose of IV palivizumab 15 mg per kilogram body weight (maximum dose =100 mg).
- Control arm: Placebo (an equivalent volume of 0.9% normal saline).
