May omega-3 fatty acid dietary supplementation help reduce severe complications in Covid-19 patients?

In around 10% of SARS-CoV-2 infected patients, coronavirus disease-2019 (Covid-19) symptoms are complicated with a severe lung damage called Acute Respiratory Distress Syndrome (ARDS), which is often lethal. ARDS is mainly associated with an uncontrolled overproduction of immune cells and cytokines, called “cytokine storm syndrome”; it appears 7–15 days following the onset of symptoms, leading to systemic inflammation and multiple organ failure. Because they are well-known metabolic precursors of specialized pro-resolving lipid mediators (SPMs), omega-3 long-chain polyunsaturated fatty acids (omega-3 LC-PUFAs) could help improve the resolution of the inflammatory balance, limiting therefore the level and duration of the critical inflammatory period. Omega-3 LC-PUFAs may also interact at different stages of the viral infection, notably on the virus entry and replication. In the absence of demonstrated treatment and while waiting for vaccine possibility, the use of omega-3 LC-PUFAs deserve therefore to be considered, based on previous clinical studies suggesting that omega-3 supplementation could improve clinical outcomes of critically ill patients at the acute phase of ARDS. In this context, it is crucial to remind that the omega-3 PUFA dietary intake levels in Western countries remains largely below the current recommendations, considering both the omega-3 precursor α-linolenic acid (ALA) and long chain derivatives such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). An optimized omega-3 PUFAs status could be helpful to prevent infectious diseases, including Covid-19.

Effect of long-chain polyunsaturated fatty acids on infant development

The ω-6 and ω-3 long-chain polyunsaturated fatty acids (LC PUFA) play a significant structural and functional role in the child’s body, as they form part of all cell membranes. ω-3 LC PUFAs are incorporated into cell membranes, increasing membrane fluidity, changing functions of receptors and membrane-bound enzymes, and, therefore, improving the interactions of the cells with their environment. This is particularly important for the development of connections between neurons in the growing child’s brain, which occurs intensively at an early age. Studies have shown the delayed effect of (ω-6 and ω-3) LC PUFA on the improvement of visual and cognitive functions. They are also the precursor of lipid mediators. The balance created by mediators ratio in the diet plays a decisive role in the prevention of common chronic diseases, including obesity. Insufficient consumption and decreased synthesis of LC PUFAs from precursors (α-linolenic and linoleic acids) in the body as a result of changed activity of fatty acid desaturas makes it necessary to include them in the food ration of nursing mothers, which is important for breastfeeding children. Formula-fed infants also need supplements with LC PUFAs. For this purpose, doctors prescribe formulas enriched with arachidonic and docosahexaenoic acids among other ingredients. This recommendation is also important at the stage of expanding nutrition by adding supplementary foods, as it is during this period that rations are especially deficient in the LC PUFAs.

Regulation mechanism of silkworm pupa oil PUFAs on cholesterol metabolism in hepatic cell L-02.

Silkworm pupa oil polyunsaturated fatty acid (SPO PUFA) has been confirmed to have a cholesterol-lowering function. The effect of SPO PUFA and its main component, α-linolenic acid (ALA), on the metabolism of cholesterol and its regulation was investigated. The model of lipid denatured cells were constructed to carry out lipid accumulation, cholesterol metabolism and transformation. Real-time PCR and western blots were also used to analyze the expression levels of related genes and proteins to investigate the cholesterol efflux regulation mechanism. The data indicated that SPO PUFA and ALA dose-dependently decreased intracellular total cholesterol (TC) and enhanced total bile acid (TBA). They could also promote cholesterol removal by enhancing bile acid secretion and by upregulating genes LXRα, PPARγ, ABCA1, ABCG1, and CYP7A1, which were regulated by LXRα/PPARγ-ABCA1/ABCG1-CYP7A1 nuclear receptor signal pathways. This study is of great significance in maintaining the balance of cholesterol and lipid metabolism, and in reducing the risk of steatohepatitis. © 2019 Society of Chemical Industry.

N-3 PUFAs improve erythrocyte fatty acid profile in patients with small AAA: a randomized controlled trial

Abdominal aortic aneurysm (AAA) is an important cause of death in older adults, which has no current drug therapy. Inflammation and abnormal redox status are believed to be key pathogenic mechanisms for AAA. In light of evidence correlating inflammation with aberrant fatty acid profiles, this study compared erythrocyte fatty acid content in 43 AAA patients (diameter 3.0-4.5 cm) and 52 healthy controls. In addition, the effect of omega-3 PUFA (n-3 PUFA) supplementation on erythrocyte fatty acid content was examined in a cohort of 30 AAA patients as part of a 12 week randomized placebo-controlled clinical trial. Blood analyses identified associations between AAA and decreased linoleic acid (LA), and AAA and increased Δ6-desaturase activity and biosynthesis of arachidonic acid (AA) from LA. Omega-3 PUFA supplementation (1.5 g DHA + 0.3 g EPA/day) decreased red blood cell distribution width (14.8 ± 0.4% to 13.8 ± 0.2%; P = 0.003) and levels of pro-inflammatory n-6 PUFAs (AA, 12.46 ± 0.23% to 10.14 ± 0.3%, P < 0.001; adrenic acid, 2.12 ± 0.13% to 1.23 ± 0.09%; P < 0.001). In addition, Δ-4 desaturase activity increased (DHA/docosapentaenoic acid ratio, 1.85 ± 0.14 to 3.93 ± 0.17; P < 0.001) and elongase 2/5 activity decreased (adrenic acid/AA ratio, 0.17 ± 0.01 to 0.12 ± 0.01; P < 0.01) following supplementation. The findings suggest that n-3 PUFAs improve fatty acid profiles and ameliorate factors associated with inflammation in AAA patients.

Is essential fatty acid interconversion an important source of PUFA in humans?

Humans can obtain pre-formed long-chain PUFA from the diet and are also able to convert essential fatty acids (EFA) to longer-chain PUFA. The metabolic pathway responsible for EFA interconversion involves alternating desaturation and carbon chain elongation reactions, and carbon chain shortening by peroxisomal β-oxidation. Studies using stable isotope tracers or diets supplemented with EFA show that capacity for PUFA synthesis is limited in humans, such that DHA (22 : 6n-3) synthesis in men is negligible. PUFA synthesis is higher in women of reproductive age compared with men. However, the magnitude of the contribution of hepatic PUFA synthesis to whole-body PUFA status remains unclear. A number of extra-hepatic tissues have been shown to synthesise PUFA or to express genes for enzymes involved in this pathway. The precise function of extra-hepatic PUFA synthesis is largely unknown, although in T lymphocytes PUFA synthesis is involved in the regulation of cell activation and proliferation. Local PUFA synthesis may also be important for spermatogenesis and fertility. One possible role of extra-hepatic PUFA synthesis is that it may provide PUFA in a timely manner to facilitate specific cell functions. If so, this may suggest novel insights into the effect of dietary PUFA and/or polymorphisms in genes involved in PUFA synthesis on health and tissue function.

Effect of PUFA Enriched Diet on Superovulatory Response, Embryo Quality, Embryo Recovery and Conception Rate in Cattle

The present study was designed to observe the effect of supplementation of PUFA enriched diet on superovulatory response, embryo quality, embryo recovery and conception in cattle. Donor (n=6) and crossbred recipient cows (n=24) were selected and divided into four groups viz; control (no treatment), T-1 (treatment given to recipient only), T-2 (treatment given to donor only) and T-3 (treatment given to both recipient and donor). The superovulatory response, mean ovulation rate ,mean embryo/ova recovered, recovery rate and average transferable embryos was found to be 75% v/s 100%, 12.25 ± 2.70 v/s 12 ± 0.71,3.5 ± 1.54 v/s 7.5 ± 1.60, 28.57% v/s 62.5 % and 50 % v/s 80 % in non-treated (control + T-1) and treated (T-2 + T-3) groups respectively. On the basis of our results, it can be concluded that flax seeds supplementation is effective in increasing above measured parameters following embryo transfer.

Cytotoxic Activity of Fatty Acids From Antarctic Macroalgae on the Growth of Human Breast Cancer Cells.

Macroalgae are a natural source of clinically relevant molecules such as polyunsaturated and monounsaturated fatty acids. The Antarctic environment, due to its cold climate, leads to high production of these bioactive molecules. Adenocystis utricularis, Curdiea racovitzae, and Georgiella confluens from three distinct islands in the Antarctic Peninsula were collected and analyzed for their fatty acid content by gas chromatography flame ionization detection. Results revealed that the algal extracts consisted of 22 fatty acids, of which 9 were saturated, 4 were monounsaturated, and 9 were polyunsaturated (PUFA). In addition, fucosterol was identified within the lipidic extracts. The cytotoxic activity of these fatty acids was evaluated in human breast cancer cell lines MCF-7 and MDA-MB-231. The most notable result was the effect of PUFA on the growth inhibition of cancer cells ranging from 61.04 to 69.78% in comparison to control cells. Significant cytotoxic activity of fatty acids from A. utricularis was observed at 48 h, resulting in an inhibition of growth of more than 50% for breast cancer cells at a concentration of 100 μg/mL. A cell viability assay showed that the fatty acids from A. utricularis significantly reduced cell viability (68.7% in MCF-7 and 89% in MDA-MB-231 after 72 h of exposure). At the same time, DAPI staining demonstrated chromatin condensation, and apoptotic bodies formed in cells that were cultured with fatty acids from A. utricularis. These data indicate that fatty acids from Antarctic macroalgae have the potential to reduce the proliferation of and induce apoptosis in breast cancer cells.

Upregulation of PPAR-γ mediates the renoprotective effect of omega-3 PUFA and ferulic acid in gentamicin-intoxicated rats

Ferulic acid (FrA) is a natural product containing phenolic compounds. ω-3 PUFA is the major constituent of fish oil. The aim of this study was to investigate the renoprotective role of FrA and FO in gentamicin (GM)-induced nephrotoxicity in rats. Forty four male rats were divided equally into 4 groups: Control group, GM group, FrA + GM group and FO + GM group. Each of the treated groups was injected with GM (40 mg/kg) i.p. for 9 consecutive days. FrA (100 mg/kg) and FO (5 mL/kg) were given to rats orally daily for 10 days prior to GM and then concomitantly with GM for additional 9 days. Kidney function was assessed by serum BUN and creatinine, urinary albumin excretion and N-acetyl-beta-D-glucosaminidase (NAG) activity and histopathological examination. The anti-inflammatory property was evaluated by measuring renal resolvin E1 and gene expression of PPAR-γ. The antioxidant activity was indicated by renal catalase (CAT) activity. GM-induced nephrotoxicity was evidenced by the renal histopathological changes along with increased renal indices. Prior and concomitant treatment with FrA or FO ameliorated nephrotoxic effect of GM as indicated by the significant decrease of serum BUN and creatinine, urinary albumin excretion and urinary NAG activity. Both treatments significantly enhanced CAT activity and gene expression of PPAR-γ. Resolvin E1 was significantly elevated in FO but not in FrA group. FrA and FO proved anti-inflammatory and renoprotective effects, which could be through their PPAR-γ agonist activity. Because FrA and FO are natural products, they could provide a safe intervention strategy in cases of exposure to nephrotoxins.

Effect of omega-3 and omega-6 polyunsaturated fatty acid enriched diet on plasma IGF-1 and testosterone concentration, puberty and semen quality in male buffalo

The objective of the present study was to evaluate the effect of omega-3 and omega-6 PUFA enriched diet on plasma IGF-1 and testosterone concentrations, puberty, sperm fatty acid profile and semen quality in male buffalo. Eighteen male buffalo calves were distributed randomly in three different groups and fed concentrate mixture along with green fodder and wheat straw in 50:40:10 ratios as per requirements. Basis ration of animals in group I was supplemented with 4% of prilled fat (PFA), while in group II and group III were added 4.67% of Calcium salt from Soybean (CaSFA) and Linseed oil (CaLFA), respectively. Male buffalo fed omega-3 PUFA high diet significantly increased concentrations of IGF-1 and testosterone in plasma as compared to two other diets (p<0.05). The age of puberty and scrotal circumference significantly increased by dietary fat effect (p<0.05) of which n-3 PUFA enriched diet (CaLFA) had the largest influence as compared to other diets (PFA and CaSFA). Feeding of n-3 PUFA rich diet significantly increased the DHA (C22:6n-3) content in sperm (p<0.05), which contributed to increased fluidity of plasma membrane, elevated quality of sperm (motility, viability) and in vitro fertility (plasma membrane integrity, acrosome integrity) in both fresh and post-thawing semen. These findings indicate that feeding of n-3 PUFA enriched diet increased IGF-1 and testosterone secretion, reduced pubertal age and improved both fresh and post-thawing semen quality in male buffalo.

Pella. 1st Department of Internal Medicine, avol Jozef Saf arik University in Ko sice Faculty of Medicine, Kosice, Slovakia * Corresponding author. Introduction: Several studies have described a positive effect of statins and omega-3 PUFA or CoQ10 on cardiovascular system. The aim of this study was to determine the effect of this triple combination on various parameters associated with the progression of cardiovascular disorders. Material and methods: 90 patients taking statins at a dose, which allowed target LDL levels, but with remained elevated TG levels (1.5-4.5 mmol/L) were randomized into three groups (each N1⁄430). In the placebocontrol group we indicated continued administration of statins. In the groups with additive treatment patients continued use of statins in combination with omega-3 PUFA 3 g/day respectively omega-3 PUFA 3 g/ day and 200 mg CoQ10/day during three months. After 3 months (± 1 week), we performed a final examination and collection of samples. We observed the lipid profile (total cholesterol, HDL, LDL, TG), hsCRP levels, activity SOD and GPx and presence of negative pleiotropic effects of statins. Results: Combination of statins with omega-3 PUFA significantly reduced TG and increased HDL levels. Significant reduction of hsCRP and increse of GTx and SOD was detected as well. Triple combination significantly decreased LDL and increased HDL in compare to control and dual combination. hsCRP significantly decreased in compare to control and dual combination group. SOD significantly increased in compare to control and dual combination group and GPx in compare to control. Conclusion: According to our study we suggest positive and complementary effect of combined therapy on lipid parameters, endothelial function and some negative pleiotropic effects of statins.

Adipose tissue dysregulation and metabolic consequences in childhood and adolescent obesity: potential impact of dietary fat quality.

Evidence suggests that at a population level, childhood and adolescent obesity increase the long-term risk of chronic diseases such as type 2 diabetes and CVD. At an individual level, however, the metabolic consequences of obesity in youth vary immensely. Despite comparable BMI, some adolescents develop impaired glucose tolerance while others maintain normal glucose homeostasis. It has been proposed that the variation in the capacity to store lipid in the subcutaneous adipose tissue (SAT) may partially discriminate metabolically healthy from unhealthy obesity. In positive energy balance, a decreased capacity to expand SAT may drive lipid accumulation to visceral adipose tissue, liver and skeletal muscle. This state of lipotoxicity is associated with chronic low-grade inflammation, insulin resistance and dyslipidaemia. The present review examines the differential adipose tissue development and function in children and adolescents who exhibit metabolic dysregulation compared with those who are protected. Additionally, the role of manipulating dietary fat quality to potentially prevent and treat metabolic dysfunction in obesity will be discussed. The findings of the present review highlight the need for further randomised controlled trials to establish the effect of dietary n-3 PUFA on the metabolic phenotype of obese children and adolescents. Furthermore, using a personalised nutrition approach to target interventions to those at risk of, or those with established metabolic dysregulation may optimise the efficacy of modifying dietary fat quality.

Effect of PUFA on patients with hypertension: a hospital based study.

Hypertension affects more than a quarter of the global adult population. Studies conducted worldwide suggest an overall small, yet useful, role of omega-3 PUFAs in reducing blood pressure in hypertensive patients. However there is no substantial data in this regard from population based in Middle East and Asia. To determine the effects of (omega-3) PUFA supplementation on the blood pressure of hypertensive patient. To identify if male and female hypertensive patients respond differently to PUFA. To identify if response of hypertensive patients to PUFA varies with the duration of hypertension and co-existence of diabetes/dyslipidemia. This observational study was conducted among hypertensive patients visiting OPD of the Gulf Medical College Hospital, Ajman, UAE, during the period Jan-Dec 2012. A total of 100 hypertensive patients on treatment with their antihypertensive medications, 50 of whom were taking n-3 PUFA supplementation, were followed up for a period of 3 months. Comparisons were drawn between the BP recordings at the time of enrollment in the study and their follow up values 3 months after enrollment. There was a statistically significant reduction in both the systolic and diastolic blood pressures after 3 months of PUFA therapy. The BP lowering effect of PUFA was more in males. A statistically significant reduction in BP was noted in non-diabetic patients and patients with long standing hypertension. Findings of the study suggest that omega-3 PUFA dietary supplements augment the benefits of pharmacotherapy in hypertension.

Matrix Metalloproteinase (MMP)-9 in Cancer-Associated Fibroblasts (CAFs) Is Suppressed by Omega-3 Polyunsaturated Fatty Acids In Vitro and In Vivo

Cancer associated fibroblasts (CAFs) are responsible for tumor growth, angiogenesis, invasion, and metastasis. Matrix metalloproteinase (MMP)-9 secreted from cancer stroma populated by CAFs is a prerequisite for cancer angiogenesis and metastasis. Omega-3 polyunsaturated fatty acids (omega-3 PUFA) have been reported to have anti-tumor effects on diverse types of malignancies. Fat-1 mice, which can convert omega-6 to omega-3 PUFA independent of diet, are useful to investigate the functions of endogenous omega-3 PUFA. To examine the effect of omega-3 PUFA on tumorigenesis, TC-1 cells, a murine epithelial cell line immortalized by human papillomavirus (HPV) oncogenes, were injected subcutaneously into fat-1 or wild type mice. Tumor growth and angiogenesis of the TC-1 tumor were significantly suppressed in fat-1 compared to wild type mice. cDNA microarray of the tumors derived from fat-1 and wild type mice revealed that MMP-9 is downregulated in fat-1 mice. Immunohistochemical study demonstrated immunoreactivity for MMP-9 in the tumor stromal fibroblasts was diffusely positive in wild type whereas focal in fat-1 mice. MMP-9 was expressed in primary cultured fibroblasts isolated from fat-1 and wild type mice but was not expressed in TC-1 cells. Co-culture of fibroblasts with TC-1 cells enhanced the expression and the proteinase activity of MMP-9, although the protease activity of MMP-9 in fat-1-derived fibroblasts was lower than that in wild type fibroblasts. Our data suggests that omega-3 PUFAs suppress MMP-9 induction and tumor angiogenesis. These findings may provide insight into mechanisms by which omega-3 PUFAs exert anti-tumor effects by modulating tumor microenvironment.

Protective effects of dietary PUFA against chronic disease: evidence from epidemiological studies and intervention trials

This review considers evidence for a protective effect of PUFA on chronic disease. Estimates of PUFA intakes in prospective cohort studies are usually based on FFQ or biomarkers of intake. Cohort studies suggest that both linoleic and linolenic acid intake are associated with a lower risk of CHD. The intake of fish, the major source of long-chain n-3 PUFA is associated with a lower risk of both stroke and CHD, particularly sudden cardiac death. No relationship with common sites of cancer (breast and colon) and PUFA has been found. However, some recent studies suggest an association of high intakes of n-3 PUFA with risk of prostate cancer. An updated Cochrane review of dietary fat modification (replacing SFA with PUFA) randomised controlled trials to prevent CHD found a 14% lower incidence and a non-significant 7% lower mortality from CHD. The effects of an increased intake of n-3 PUFA on CHD incidence mortality have been tested in patients with pre-existing CHD in randomised controlled trials. Meta-analysis of these trials showed no overall benefit on total mortality or CVD incidence but a trend for lower risk of cardiac death was 0·91 (95% CI 0·85, 0·98). At present, there is little evidence from other trials demonstrating the clear benefits or harm from increased intakes of PUFA. In conclusion, present evidence intakes benefit from partial replacement of SFA with a balanced mixture of n-6 and n-3 PUFA which may contribute to CVD prevention.

Bioactive Fish Fatty Acids: Health Effects and Their Use as Functional Food Ingredients

The nutritional benefits of fish or fish oil consumption lies predominantly in its advantageous fatty acid profile, which is rich in long chain omega-3 polyunsaturated fatty acids (ω3 PUFA). Evidence from a large number of epidemiological studies, clinical studies and intervention trials have established the protective effect of ω3 PUFA against several diseases. New experimental evidence also indicates the presence in fish oils of other class of bioactive fatty acids, such as the furan fatty acid (F-acids). Dietary recommendations suggest that the consumption of ω3 PUFA should be increased. The great variability of fatty acid composition of fish species throughout the year should be considered when fish are suggested as a means of improving health or used for oil extraction. The fish oil remains the principal source of ω3 PUFA as an ingredient into conventional food products enrichment and in ω3 PUFA concentrates production (i.e. integrator, nutraceutical), even if a variety of alternative ω3 PUFA sources, such as bacteria, fungi, plants and microalgae are currently being explored for commercial production. The present review summarizes the beneficial effects of ω3 PUFA dietary supplementation on cardiovascular disease, neurological disorder and type 2 diabetes as well as the biological actions of F-acids. Furthermore, in order to present the fish as a dietary source of bioactive fatty acids, differences in fatty acid composition of various fish species are recognized. The alternative ways to ensure an optimal ω3 PUFA intake are also provided by illustrating the possible applications of fish oil on the ω3 PUFA enrichment of functional foods.
