The benefits of antioxidants or DHA/EPA supplementation for CF , although observed in some studies , are not consistent enough to recommend routine use of these supplements .
Antioxidant micronutrients and essential fatty acids supplementation intake appears to have a protective effect in some diseases such as cardiovascular disease , cancer , and asthma .
The aim of this study was to perform a systematic review to evaluate the effects of these nutrients on nutritional and clinical outcomes of patients with cystic fibrosis ( CF ) .
This is a systematic review of r and omized clinical trials ( RCTs ) in CF .
Supplementation With Fatty Acids Influences the Airway Nitric Oxide and Inflammatory Markers in Patients With Cystic Fibrosis
Objectives : To obtain a balance in the fatty acid ( FA ) metabolism is important for the inflammatory response and of special importance in cystic fibrosis ( CF ) , which is characterized by impaired FA metabolism , chronic inflammation , and infection in the airways . Nitric oxide ( NO ) has antimicrobial properties and low nasal ( nNO ) and exhaled NO ( FENO ) , commonly reported in CF that may affect bacterial status . The present study investigates the effect of different FA blends on nNO and FENO and immunological markers in patients with CF . Patients and Methods : Forty-three patients with CF and “ severe ” mutations were consecutively enrolled in a r and omized double-blind placebo-controlled study with 3 FA blends containing mainly n-3 or n-6 FA or saturated FA acting as placebo .  FENO , nNO , serum phospholipid concentrations of FA , and biomarkers of inflammation were measured before and after 3 months of supplementation . Results : Thirty-five patients in clinical ly stable condition completed the study . The serum phospholipid FA pattern changed significantly in all 3 groups . An increase of the n-6 FA , arachidonic acid , was associated with a decrease of FENO and nNO . The inflammatory biomarkers , erythrocyte sedimentation rate , and interleukin-8 decreased after supplementation with n-3 FA and erythrocyte sedimentation rate increased after supplementation with n-6 FA . Conclusions : This small pilot study indicated that the composition of dietary n-3 and n-6 FA influenced the inflammatory markers in CF . FENO and nNO were influenced by changes in the arachidonic acid concentration , supporting previous studies suggesting that both the lipid abnormality and the colonization with Pseudomonas influenced NO in the airways
