OBJECTIVE To determine the clinical utility of fatty acid ethyl esters (FAEEs) in the blood as a short-term confirmatory marker for ethanol intake and a longer-term marker for ethanol intake after ethanol is no longer detectable. DESIGN Single-center controlled clinical trial and a blinded comparison involving 48 blood samples that were positive,(More)
OBJECTIVE To assess the clinical efficacy and adverse effects of gamma-linolenic acid (GLA), a plant seed oil-derived unsaturated fatty acid that suppresses inflammation and joint tissue injury in animal models, in the treatment of active rheumatoid arthritis (RA). METHODS Fifty-six patients with active RA were randomized to treatment groups in a 6-month,(More)
BACKGROUND Patients with cystic fibrosis have altered levels of plasma fatty acids. We previously demonstrated that arachidonic acid levels are increased and docosahexaenoic acid levels are decreased in affected tissues from cystic fibrosis-knockout mice. In this study we determined whether humans with mutations in the cystic fibrosis transmembrane(More)
The promise of "personalized medicine" guided by an understanding of each individual's genome has been fostered by increasingly powerful and economical methods to acquire clinically relevant information. We describe the operational implementation of prospective genotyping linked to an advanced clinical decision-support system to guide individualized health(More)
BACKGROUND Current evidence from both experimental and human studies indicates that omega-6 polyunsaturated fatty acids (n-6 PUFAs) promote breast tumor development, whereas long-chain n-3 polyunsaturated fatty acids (n-3 PUFAs) exert suppressive effects. The ratio of n-6 to n-3 fatty acids appears to be an important factor in controlling tumor development.(More)
BACKGROUND Fatty acid ethyl esters (FAEE), nonoxidative products of ethanol metabolism, are formed by the esterification of fatty acids and ethanol. Alcoholic subjects have high levels of FAEE in the circulation as well as in organs and tissues, especially those most often damaged by ethanol abuse. Our previous studies showed a significant synthesis of FAEE(More)
We administered borage seed oil (9 capsules/day) for 12 weeks to 7 normal controls and to 7 patients with active rheumatoid arthritis. The therapy provided 1.1 gm/day of gamma-linolenic acid (GLA). GLA administration resulted in increased proportions of its first metabolite, dihomo-gamma-linolenic acid (DGLA), in circulating mononuclear cells. The ratios of(More)

The number of tests used for the detection of ethanol ingestion is increasing. The field is rapidly moving beyond ethanol alone as a marker of ethanol intake. The combined measurement of carbohydrate deficient transferrin, FAEEs, 5-HTOL/5-HIAA, acetaldehyde adducts, and phosphatidylethanol may one day be used to approximate the time and amount of ethanol(More)
Fatty acid ethyl esters (FAEE), esterification products of ethanol and fatty acids, have been implicated as mediators of ethanol-induced organ damage. After ethanol ingestion in humans, FAEE circulate in blood, bound to lipoproteins and albumin. We have analyzed the binding of ethyl (1-13C, 99%) oleate (EO) to small unilamellar phospholipid vesicles (SUV),(More)
BACKGROUND Fatty acid ethyl esters (FAEEs) are nonoxidative metabolites of ethanol produced by the esterification of fatty acids and ethanol. FAEEs have been implicated as mediators of ethanol-induced organ damage in vivo and in vitro. They are detectable in the blood and in many organs after ethanol ingestion, and on this basis they are useful markers of(More)
