Detailed Description:

The hallmarks of cystic fibrosis (CF) are recurrent severe and destructive pulmonary inflammation and infection, beginning in early childhood and leading to morbidity and mortality due to respiratory failure. During the disease, most children become colonized with Pseudomonas aeruginosa (PA) and undergo progressive impairment of respiratory function. Therefore, patients colonized with Pseudomonas are at increased risk for pulmonary infections and persistent inflammation and have a decrease in survival rate. In an attempt to reduce the rate and severity of pulmonary exacerbations, children with CF are put on heavy load of antibiotics.

Intestinal inflammation is another typical finding in CF patients and gut bacterial overgrowth may be present.

Probiotics are live bacteria administered orally, successfully used in children with acute gastroenteritis, as well as in preventing and treating atopic diseases in children. In addition, probiotics have been used as adjuvant therapy in patients with pouchitis and inflammatory bowel diseases. Interestingly, probiotic supplementation is able to reduce the incidence of fever, child care absences, antibiotic prescription and to prevent nosocomial gastrointestinal and respiratory infections. The effect of probiotics may be through improvement of intestinal barrier function and modulation of immune response. The latter mechanism could well explain the clinical effects of probiotics observed in extraintestinal diseases.
