Antibiotic Treatment of Recurrent Episodes of Asthma in Children (AB-studie)

This study is ongoing, but not recruiting participants.

Copsac has discovered that asthmatic exacerbations are as closely linked to bacterial as to viral infection. The current study will examine whether treatment of asthmatic exacerbations with macrolide antibiotics - in the abscence of clear clinical bacterial infection which would in any case precipitate antibiotic treatment - has an effect on either the particular episode, or subsequently. Macrolide antibiotics are chosen for ease of administration ensuring high compliance, antibiotic appropriacy, and anti-inflammatory properties.

Primary Outcome Measures:
  • Symptom scoring [ Time Frame: 1 to 3 years of age ]
  • Duration in days of each asthmatic episode from randomisation start [ Time Frame: 1 to 3 years of age ]

Secondary Outcome Measures:
  • need for PO steroids during the episode [ Time Frame: 1 to 3 years of age ]
  • beta-agonist use during the asthmatic episode [ Time Frame: 1 to 3 years of age ]
  • time lapse until the next asthmatic episode [ Time Frame: 1 to 3 years of age ]
  • MD assessment of the episode [ Time Frame: 1 to 3 years of age ]
  • Family's assessment of the episode [ Time Frame: 1 to 3 years of age ]
  • Asthma related health and economic assessment [ Time Frame: 1 to 3 years of age ]
  • percentage of time away from kindergarten or, for the parents, away from work [ Time Frame: 1 to 3 years of age ]
  • stratification of the above parameters according to bacterial colonisation of the airways [ Time Frame: 1 to 3 years of age ]
