Evaluation of the relationship between endometriosis and omega-3 and omega-6 polyunsaturated fatty acids

Endometriosis is a common chronic inflammation causing major problems including infertility. The role of omega-3 and omega-6 fatty acids as their potential anti-inflammatory effects in endometriosis needs to be further explored. The objective of this study was to compare serum phospholipid fatty acid profile in endometriosis patients with controls, and to explore the correlation of this profile with the severity of the disease. Sixty-four endometriosis patients and 74 control women, in reproductive age, participated in this study. Among the endometriosis patients, 19 cases were in stage I, 27 cases in stage II, 8 cases in stage III, and 10 cases in stage IV. Each patient underwent laparoscopy. Before surgery, 5 ml of blood was obtained. After extraction of the total lipids, serum total phospholipid fraction was isolated by thin layer chromatography. Fatty acid composition of the phospholipid fraction was determined by gas chromatography and the resulted profile was compared in endometriosis patients and controls. The profile was also compared in the endometriosis group based on the severity of disease. Stearic acid was significantly lower in the endometriosis group as compared to controls [P= 0.030]. No other fatty acid compositions were significantly different between patients and controls. Serum ratio of eicosapentaenoic acid [EPA] to arachidonic acid [AA] was in reasonable correlation with the severity of endometriosis [r = 0.34, P = 0.006]. According to these findings, levels of fatty acids in serum total phospholipids seem not to be a marker for endometriosis, but the EPA to AA ratio was a relevant factor indicating severity of illness

[Plasma fatty acids Profile and lipids in Tunisian male elite athletes]

Growing interest is accorded to polyunsaturated fatty acids [PUFAs] 3, which are considered beneficial for health. To investigate the effect of sports on plasma lipids and fatty acids [FAs], especially 6 and 3 PUFAs and the 6/3 ratio. The study included 75 Tunisian male elite athletes, practicing team sport and 70 sedentary healthy men as controls. Plasma FAs profile was analyzed by gas chromatography. Comparison between groups was performed using a univariate GLM analysis, with adjustment on age, body mass and energy intake. Athletes showed lower triglycerides and saturated FAs [27.64% +/- 2.17% vs. 30.41% +/- 4.35%] and increased HDL cholesterol and monounsaturated FAs [21.19% +/- 2 44% vs. 19.12% +/- 3.03%]. However, there was no significant difference in total PUFAs, 6 and 3 families and 6/3 ratio [10.15% +/- 3.24% vs. 10.20% +/- 3.37%] between athletes and sedentary. Sport favorably modifies the profile of plasma FAs by increasing monounsaturated FAs at the expense of saturated FAs, but has no effect on total PUFAs, and 6 and 3 families. A diet rich in 3 PUFAs would lower the 6/3 ratio, in order to improve the health and probably the performance of athletes

Beneficial antipsychotic effects of omega-3 fatty acids add-on therapy for the pharmacological management of patients with schizophrenia

It has been shown that serum and red blood cells-level of Omega-3 fatty acids are low in people with schizophrenia. Many studies have, therefore, attempted to explore the beneficial effects of these substances in the management of Schizophrenia. However, the outcomes of the previous studies have not been clear cut. The present study is an attempt to retest this hypothesis by eliminating some of the limitations of the previous studies. In a prospective double blind placebo-controlled clinical trial, 85 inpatients with schizophrenia randomly assigned to either risperidone plus Omega-3 or risperidone plus placebo. After a washout period, 44 patients received 2-8 mg/day of risperidone plus placebo and 43 patients received risperidone plus 3 gr/day of Omega-3 for 6 weeks. The treatment effect was calculated by Friedman, Mann Whitney and t test. There were no significant differences between groups in age, sex, education, duration of illness and the number of previous hospitalizations. There were no statistically significant differences in the scores of Positive and Negative Syndrome Scale between two groups at weeks 0, 3 and 6 and for the whole duration of the study. In our study, Omega-3 fatty acids had no superiority to placebo in reducing the positive and negative symptoms of schizophrenia. However, due to a short duration of our study, we recommend that more long term clinical trials are needed in order to develop a better understanding of the therapeutic effects of the Omega-3 fatty acids in the pharmacological management of schizophrenia

Platelet fatty acids in coronary heart disease, dyslipidemia, hypertension and healthy controls.

A cross-sectional study was performed to investigate 250 volunteers from Pramongkutklao Hospital, Samphanthawong district, Wat Chaiyapreukmala and Wat Pradoo in Taling Chan district. They were divided into groups of 35 apparently healthy males, 16 males with coronary heart disease, 37 males with dyslipidemia and 9 males with hypertension with age ranges of 24-62, 56-69, 25-69 and 26-75 years, respectively. The female groups were composed of 55 apparently healthy females, 10 females with coronary heart disease, 73 females with dyslipidemia and 15 females with hypertension with age ranges of 27-65, 33-67, 22-73 and 38-70 years, respectively. Platelet fatty acids levels were found to have no significant difference between the different male groups. In the female groups, the alpha-linolenic acid (ALA) level in hypertension was significantly higher than in coronary heart disease (CHD) (p<0.05), whereas the arachidonic acid (AA) level in hypertension was significantly higher than in the apparently healthy females (p<0.05). No correlation was found between platelet fatty acids and age or anthropometric parameters, which indicate that platelet fatty acids may not depend on either age or anthropometric parameters. Positive correlations were shown between ALA and eicosapentaenoic acid (EPA), AA and docosahexaenoic acid (DHA), ALA and the diastolic blood pressure, DHA and total cholesterol (TC), and between low density lipoprotein choleoterol (LDL-C) and plasma glucose. Negative correlations were shown between LA and EPA, AA and EPA, EPA and DHA, EPA and the systolic blood pressure, and AA and the diastolic blood pressure.
