Brief Summary

The overall objective of the study is to determine the efficacy of corticosteroids in preventing recurrent wheezing and asthma in high-risk, first-time severe wheezing children with rhinovirus infection, stratified by rhinovirus genome load. The secondary objectives are to determine duration and severity of each acute episode with acute expiratory breathing difficulty, the number of episodes with acute expiratory breathing difficulty, degree of pulmonary hyperreactivity and quality of life within 24 months after study entry.

Eligibility Criteria

Inclusion Criteria: * admitted to pediatric acute wards in the participating hospitals in Norway, Finland, Sweden. * referred for first severe wheezing episode, defined as first-time acute breathing difficulty with wheezing ever, appearing less than 7 days from onset of symptoms * one or more of the following:(a) fever, (b) hypoxia (SAT O2 \<= 92%), (c) retractions (inter-, subcostal), (d) prolonged expiration (on auscultation), (e) expiratory rhonchi (on auscultation) * evidence of rhinovirus infection by PCR-test in nasopharyngeal secretions * signed informed consent and expected cooperation of the patients for the treatment and follow-up must be obtained and documented according to ICH GCP, and national/local regulations. Exclusion Criteria: * previous episodes with wheezing, defined as a history of acute breathing difficulty with wheezing in need of treatment at a general practitioner or at hospital, or parental information about similar breathing difficulties * gestational age \<37 weeks * chronic illness other than atopy (eczema), * previous systemic or inhaled corticosteroid treatment, * participation to another trial, * varicella infection or contact during the last 2-3 weeks, * need for intensive care unit treatment during the present infection, except for respiratory support with non-invasive methods (high flow nasal cannula ventilation, CPAP or BiPAP), * any reason why, in the opinion of the investigator, the patient should not participate (e.g. not able to comply with study procedures). * COVID-19 related disease.
