Clinical effects of diet supplementation with DHA in pediatric patients suffering from cystic fibrosis.
OBJECTIVE
Cystic fibrosis (CF) patients present an altered fatty acid (FA) metabolism characterized by imbalance in the arachidonic/docosohexasenoic acid (AA/DHA) ratio in favour of the former which can contribute to the increase in pulmonary inflammation. The present study aims to assess respiratory, nutritional, clinical and laboratory parameters, and inflammatory markers after six months of DHA supplementation in paediatric patients suffering from CF.


METHODS
A dose of 1 g/10 kg/die was administered to ten CF patients of paediatric age for the first month and 250 mg/10 kg/die for the remaining 5 months. We carried out follow-ups at T0 (baseline), T6 (after six months of the diet) and T12 (six months after supplementation was interrupted) during which respiratory, nutritional, clinical and laboratory parameters were assessed.


RESULTS
After six months of DHA supplementation inflammatory marker levels had diminished: interleukin 8 (IL-8) and Tumour Necrosis Factor Alfa (TNF-α) in serum, and calprotectin in stools. In addition, auxometric parameters were improved as was the clinical condition of patients, who tolerated DHA well.


CONCLUSIONS
Dietetic integration with DHA seems to improve clinical condition and the inflammatory pulmonary and intestinal state of pediatric patients suffering from CF.
