This study examined the effects of supplementing patients with
cystic fibrosis daily for 4 weeks with 1,500 mg borage oil
containing 330 mg gamma-linolenic acid on the fatty acid
composition of serum phospholipids (PL) and cholesteryl esters
(CE). Vital capacity and forced expiratory volume in 1s were also
measured before and after treatment. In serum PL the content of
arachidonic acid (AA) increased and that of palmitic acid
decreased
significantly after borage oil administration. In serum CE
dihomogamma-linolenic acid increased whereas docosahexaenoic
acid
decreased significantly. In this lipid class AA and the sum of AA
plus its precursor dihomo-gamma-linolenic acid increased
significantly with the dose fed. A positive correlation was found
between change in vital capacity and change in linoleic acid
content of serum CE and AA content of serum PL.
