ACTA PAEDIATRICA, Issue 12 2009
MC Marín
Abstract Aim:, To determine the effect of dietary supplementation with n-3 fatty acids (FA) in paediatric burned patients who had less than 20% of total body surface affected. Methods:, Burned patients were randomly assigned into two groups, one of them received a supplement of n-3 FA during 5 weeks; the other group was considered as not n-3 supplemented burned group. A third group of no burned patients was selected as control. Blood samples were collected at admission and in burned groups at the final of the study. Plasma and erythrocyte phospholipid FA composition and some biochemical parameters related to the clinical evolution: total plasma proteins and C3 and C4 complement proteins were determined. Results:, In the early post-burn patients, there is an increase in saturated and monounsaturated FAs in plasma phospholipids, and a decrease in polyunsaturated FAs compared with control. These alterations are in favour of proinflammatory response to burn injury. In n-3 FA supplemented group, these changes were further reverted, and a favourable response in the amount of total plasma proteins and in C3 and C4 proteins of the complement system was demonstrated. Conclusion:, Dietary n-3 FA supplementation might be beneficial for patients suffering thermal injury. [source]


n-3 polyunsaturated fatty acid supplementation, monocyte adhesion molecule expression and pro-inflammatory mediators in Type 2 diabetes mellitus

SUMMARY Aims To examine the effect of n-3 polyunsaturated fatty acid supplements on the monocyte surface expression of adhesion molecules involved in pro-atherogenic monocyte,endothelial interactions, and on pro-inflammatory mediators in Type 2 diabetes mellitus. Methods Twenty-nine subjects with Type 2 diabetes and 21 controls without diabetes were studied. Monocyte expression of leucocyte function-associated antigens 1 and 3, intercellular adhesion molecule-1, and the major histocompatibility complex class II molecule HLA-DR were measured using a laser flow cytometric method. Supplementation with 2.08 g n-3 fatty acids for 21 days was undertaken and measurements repeated. Plasma soluble adhesion molecule concentrations, plasminogen activator inhibitor-1 activity and antigen and pro-inflammatory mediators (cysteinyl leukotriene and monocyte leukotriene B4) were also measured. Results Groups did not differ in monocyte expression of adhesion molecules or HLA-DR, or in leukotriene production although plasma soluble adhesion molecule concentrations were higher in the diabetes groups (P < 0.05). n-3 fatty acid supplementation influenced neither the expression of these molecules nor plasma soluble adhesion molecule concentrations or leukotriene production. Conclusions This study does not support increased monocyte adhesion molecule expression or abnormal monocyte production of pro-inflammatory mediators as mechanisms for increased atherogenic risk in Type 2 diabetes. Cardioprotective actions of n-3 fatty acids may not be mediated through these mechanisms. [source]


Treatment of Hypertriglyceridemia With Omega-3 Fatty Acids: A Systematic Review

JOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 9 2004
Amanda Lewis MS
Purpose To (a) critically appraise available randomized controlled trials (RCTs) addressing the efficacy of long-chain omega-3 fatty acids as secondary agents for prevention of hypertriglyceridemia and (b) make recommendations for clinical practice. Data Sources Two independent reviewers examined all RCTs from 1994 to 2003 identified in several databases, extracted data from each study, and used the previously tested Boyack and Lookinland Methodological Quality Index (MQI) to determine study quality. Conclusions Ten studies reported long-chain omega-3 fatty acids to be effective in the treatment of hypertriglyceridemia. The average decrease in triglycerides was 29%, total cholesterol 11.6%, very low density lipoprotein (VLDL) 30.2%, and low-density lipoprotein (LDL) 32.5%. One study found LDLs to increase by 25%. The average increase in highdensity lipoprotein was 10%. The overall average MQI score was 36% (range = 26% to 54%). Many of the RCTs had serious shortcomings, including short duration, lack of a power analysis, no intention-to-treat analysis, no report of blind assessment of outcome, and lack of dietary control as a confounding variable. Implications for Practice Overall study methodology was weak. Although the evidence supporting use of long-chain omega-3 fatty acids in the secondary prevention of hypertriglyceridemia is reasonably strong, until there are larger RCTs of better methodological quality, it is not recommended that practitioners treat hypertriglyceridemia with omega-3 fatty acid supplementation in lieu of lipid-lowering medications.

Gracious BL, Chirieac MC, Costescu S, Finucane TL, Youngstrom EA, Hibbeln JR. Randomized, placebo-controlled trial of flax oil in pediatric bipolar disorder. Bipolar Disord 2010: 12: 142,154. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objectives:, This clinical trial evaluated whether supplementation with flax oil, containing the omega-3 fatty acid ,-linolenic acid (,-LNA), safely reduced symptom severity in youth with bipolar disorder. Methods:, Children and adolescents aged 6,17 years with symptomatic bipolar I or bipolar II disorder (n = 51), manic, hypomanic, mixed, or depressed, were randomized to either flax oil capsules containing 550 mg ,-LNA per 1 gram or an olive oil placebo adjunctively or as monotherapy. Doses were titrated to 12 capsules per day as tolerated over 16 weeks. Primary outcomes included changes in the Young Mania Rating Scale, Child Depression Rating Scale-Revised, and Clinical Global Impressions-Bipolar ratings using Kaplan-Meier survival analyses. Results:, There were no significant differences in primary outcome measures when compared by treatment assignment. However, clinician-rated Global Symptom Severity was negatively correlated with final serum omega-3 fatty acid compositions: %,-LNA (r = ,0.45, p < 0.007), % eicosapentaenoic acid (EPA) (r = ,0.47, p < 0.005); and positively correlated with final arachidonic acid (AA) (r = 0.36, p < 0.05) and docosapentaenoic acid (DPA) n-6 (r = 0.48, p < 0.004). The mean duration of treatment for ,-LNA was 11.8 weeks versus 8 weeks for placebo; however, the longer treatment duration for ,-LNA was not significant after controlling for baseline variables. Subjects discontinued the study for continued depressive symptoms. Conclusions:, Studies of essential fatty acid supplementation are feasible and well tolerated in the pediatric population. Although flax oil may decrease severity of illness in children and adolescents with bipolar disorder who have meaningful increases in serum EPA percent levels and/or decreased AA and DPA n-6 levels, individual variations in conversion of ,-LNA to EPA and docosahexaenoic acid as well as dosing burden favor the use of fish oil both for clinical trials and clinical practice. Additionally, future research should focus on adherence and analysis of outcome based on changes in essential fatty acid tissue compositions, as opposed to group randomization alone. [source]


Nutrition, mood and behaviour: a review

ACTA NEUROPSYCHIATRICA, Issue 5 2009
Nerissa L Soh
Objective: To conduct a critical review of recent empirical research regarding mood, behaviour and nutrition factors including essential fatty acids, macronutrients, micronutrients and food additives. Method: A literature search of databases Medline, PsycInfo, CINAHL and Embase up to October 2008. The search emphasised empirical research published in the last 10 years and also included older literature. Studies in both adults and children were addressed. Results: Research into omega-3 fatty acids has been substantial but evidence for their potential in treating mood and behaviour is modest. In comparison, there has been much less research into carbohydrate and protein intakes and little evidence for their ability to influence mood and behaviour. Recent trials with food additives suggest their removal from the diet may benefit susceptible children with hyperactivity disorders. Micronutrient supplementation appears to improve mood only in those who were initially deficient in micronutrients. Conclusions: More stringent research designs such as longitudinal studies and the use of biologically inert placebos within randomised controlled trials are needed before supplemental use of omega-3 fatty acids to treat disorders of mood and behaviour can be recommended. Caution is advised regarding the indiscriminate use of diets free of artificial food additives in managing hyperactivity disorders, as they may place an undue burden on individuals and their families. Should omega-3 fatty acid supplementation or the elimination of certain food additives be established as effective, they may provide cost-effective, accessible and well-tolerated adjuncts to standard psychiatric treatments for mood and behavioural disturbances.

Abstract Maternal intake of omega- 3 (,-3) polyunsaturated fatty acids (PUFAs) during pregnancy has decreased, possibly contributing to a current increased risk of childhood allergy. Aim:, To describe the effects of maternal ,-3 long-chain PUFA supplementation during pregnancy and lactation on the incidence of allergic disease in infancy. Methods:, One hundred and forty-five pregnant women, affected by allergy themselves or having a husband or previous child with allergies, were included in a randomized placebo-controlled trial. Daily maternal supplementation with either 1.6 g eicosapentaenoic acid and 1.1 g docosahexaenoic acid or placebo was given from the 25th gestational week to average 3,4 months of breastfeeding. Skin prick tests, detection of circulating specific immunoglobulin E (IgE) antibodies and clinical examinations of the infants were performed. Results:, The period prevalence of food allergy was lower in the ,-3 group (1/52, 2%) compared to the placebo group (10/65, 15%, p < 0.05) as well as the incidence of IgE-associated eczema (,-3 group: 4/52, 8%; placebo group: 15/63, 24%, p < 0.05). Conclusion:, Maternal ,-3 fatty acid supplementation may decrease the risk of food allergy and IgE-associated eczema during the first year of life in infants with a family history of allergic disease.

Essential fatty acids supplementation in different-stage atopic dogs fed on a controlled diet

JOURNAL OF ANIMAL PHYSIOLOGY AND NUTRITION, Issue 3-6 2005

Summary The aim of this trial was to evaluate the effects of polyunsaturated fatty acid (PUFA) supplementation in different-stages atopic dogs fed on a controlled diet. Twenty-two non-seasonal atopic dogs of different breeds and ages were included in the 2-month trial. All the patients were given an essential fatty acid (EFA) supplementation [17 mg/kg eicosapentaenoic acid (EPA) + 5 mg/kg docosahexaenoic acid (DHA) + 35 mg/kg gammalinolenic acid (GLA)], the global (diet + supplementation) , -6 to , -3 ratio was 5.5,1. Two groups of dogs were considered: group A ,pre-immunotherapy' (15 cases) included dogs with early stages atopy, which had not been submitted to any treatment yet; group B ,post-immunotherapy' (seven cases) included dogs with chronic atopy immunotherapy non-responsive. Clinical evaluations were performed at the beginning, on day 30 and at the end of the trial. Blood serum fatty acids profile was determined at the beginning and at the end of the study. Better clinical results were obtained in group A, a great difference was found between the two groups on pruritus score. Serum arachidonic acid (AA) was significantly lower at the end of the trial in group A while GLA was significantly higher in group B. We hypothesized that different-stages atopic dogs could have different response to EFA supplementation, maybe because of a different fatty acids metabolism. Early stages cases seem to be more responsive to EFA supplementation. [source]
