Interpretation
* Test performed at Mayo Medical Laboratories, Rochester, MN. Test interpretation provided by The Great Plains Laboratory, Inc.
Nutritional requirements for essential fatty acids (omega-3, and omega-6 series) vary by age. Deficiency may be measured by the Holman index, also called the triene/tetraene ratio (mead-to-arachidonic acid ratio). Deficiencies are commonly caused by inadequate dietary intake of lipids or intestinal malabsorption. Signs include scaly dermatitis, alopecia, thrombocytopenia, and, in children, growth retardation. Infant fed diets low in linoleic acid, such as skim-milk formula, can develop essential fatty acid deficiency. Biochemical abnormalities may be detected before the onset of recognizable clinical manifestations and treated with appropriate nutritional supplementation that usually includes linoleic and alpha-linolenic acids.
Additionally, studies have shown that major depression is accompanied by alterations in essential fatty composition such as reduced omega-3 fatty acids and an increased arachidonic-to-eicosapentaenoic acid ratio. Pregnancy leads to depletion of maternal docosahexanoic acid (DHA), and after delivery maternal DHA steadily declines further. Pregnant women who are at risk to develop postpartum depression may benefit from a prophylactic treatment with a combination of eicosapentaenoic and docosahexanoic acids.
Fatty acid oxidation disorders are recognized on the basis of disease-specific patterns that are correlated to the results of other tests in plasma (carnitine, acylcarnitines) and urine (organic acids, acylglycines).
Increased concentrations of tetracosanoic (lignoceric) and hexacosanoic acids are useful in the diagnosis of peroxisomal disorders, X-linked adrenoleukodystrophy, adrenomyeloneuropathy, and Zellweger syndrome (cerebrohepatorenal syndrome).
Increased concentrations of phytanic acid are useful in the biochemical diagnosis of Refsum disease. Refsum's disease is a peroxisomal disorder caused by phytanase deficiency, an enzyme involved in phytanic acid oxidation. In this case, the level of phytanic acid is elevated and pristanic acid is normal.
An elevated omega-6 to omega-3 ratio may promote the pathogenesis of many diseases, including cardiovascular disease, cancer, inflammatory and autoimmune diseases. A lower ratio of omega-6 to omega-3 fatty acids is more desirable in reducing the risk of many of the chronic diseases of high prevalence. The optimal ratio may vary with the medical condition under consideration. An omega-6 to omega-3 ratio of 4 has been associated with a 70% decrease in total mortality, and it appears to be the optimal ratio for brain-mediated functions. A ratio of 2.5 has been shown to suppress cell proliferation in patients with colorectal cancer. A reduced omega-6 to omega-3 ratio of 2 to 3 suppressed inflammation in patients with rheumatoid arthritis. Western diets are considered deficient in omega-3 fatty acids with an omega-6 to omega3 ratio greater than 10. See chart on Page 5.
