Gamma-linolenic acid supplementation for prophylaxis of atopic dermatitis--a randomized controlled trial in infants at high familial risk.
BACKGROUND Studies suggest that low concentrations of n-6 long-chain polyenes in early life are correlated to atopic disease in later life . OBJECTIVE The purpose of the study was to investigate the possible preventive effect of gamma-linolenic acid ( GLA ) supplementation on the development of  atopic dermatitis in infants at risk . DESIGN In a double-blind , r and omized , placebo-controlled trial , formula-fed infants ( n = 118 ) with a maternal history of atopic disease received borage oil supplement ( containing 100 mg GLA ) or sunflower oil supplement as a placebo daily for the first 6 mo of life . Main outcome measures were the incidence of atopic dermatitis in the first year of life ( by UK Working Party criteria ) , the severity of atopic dermatitis ( SCORing Atopic Dermatitis ; SCORAD ) , and the total serum immunoglobulin E ( IgE ) concentration at the age of 1 y. RESULTS The intention-to-treat analysis showed a favorable trend for severity of atopic dermatitis associated with GLA supplementation ( x+/- SD SCORAD : 6.32 + /- 5.32 ) in the GLA-supplemented group as compared with 8.28 + /- 6.54 in the placebo group ( P = 0.09 ; P = 0.06 after adjustment for total serum IgE at baseline , age 1 wk ) , but no significant effects on the other atopic outcomes . The increase in GLA concentrations in plasma phospholipids between baseline and 3 mo was negatively associated with the severity of atopic dermatitis at 1 y ( Spearman 's correlation coefficient = -0.233 , P = 0.013 ) . There was no significant effect on total serum IgE concentration . CONCLUSION Early supplementation with GLA in children at high familial risk does not prevent the expression of atopy as reflected by total serum IgE , but it tends to alleviate the severity of atopic dermatitis in later infancy in these children
