Abstract CLDs in children are chronic inflammation of the airways and other parts of the lung .Omega 3 fatty acids competitive inhibit the formation of LTB-4 and PG from arachidonic acids. Aim: Assess the role of Omega-3 fatty acids supplementation in treatment of chronic lung diseased children in Egypt.. Methods: Our study was conducted on 20 children with chronic lung disease and 10 healthy children as control .Each child had taken 300 mg DHA and 700 mg EPA for 60 days. Serum level of DHA was measured by HPLC method as well as PFTs were measured before and after supplementation. Results: The serum level of DHA and PFTs were significantly lower in chronic lung diseased children compared to controls before and after intake of DHA supplementation. The highly significant increase in the mean value of DHA serum level in the cases after supplementation (10.2±0.7 μg/ml), was associated with highly significant increase in the mean value of FVC and FEV1after supplementation.Serum level of DHA was significantly positively correlated to PFTs ( FVC and FEV1). Conclusion: Omege-3 fatty acids dietary supplementation is a promising tool and may provide a valuable adjunct therapeutic modality for treatment of pediatric chronic lung diseases for future longitudinal assessment. |
