Study Arms (2)
1: Borage Seed Oil and Echium Seed Oil
EXPERIMENTALBorage/Echium plant seed oils: 2 g/day of borage seed oil and 7 g/day of echium seed oil to provide 1.6 g/day of GLA and 0.9 g/day of SDA.
2: Placebo Comparator
PLACEBO COMPARATORPlacebo comparator: 9 g/day corn oil
Interventions
2 g/day of borage seed oil and 7 g/day of echium seed oil to provide 1.6 g/day of GLA and 0.9 g/day of SDA.
Eligibility Criteria
You may qualify if:
- Diagnosis of bronchial asthma
- Male or female 18 years to 65 years of age
- FEV1 50 to 90% of predicted, or personal best.
- Improvement of \>=12% FEV1 with bronchodilator
You may not qualify if:
- Pregnant or nursing
- Smoking history of \> 10 pack years or active smoking within the past year.
- leukotriene modifying drugs,
- theophylline
- oral steroids.
- dietary supplements with fatty acids or other products that may interfere with leukotriene generation.
- Treatment within the previous three months with omalizumab (monoclonal antibody directed against IgE)
- Subjects will not be permitted to take non-steroidal anti-inflammatory drugs in the week prior to any measurements of ex vivo leukotriene generation because of their effects on leukotriene biosynthesis via inhibition of prostaglandin generation.
- A history of aspirin-sensitive asthma
- Significant abnormalities in CBC, differential white cell count, renal function, and liver function, or urinalysis.
- Any serious co-morbid medical condition.
