Noncommunicable diseases (NCD) and age-associated diseases (AAD) are some of the gravest health concerns worldwide, accounting for up to 70% of total deaths globally. NCD and AAD, such as diabetes, obesity, cardiovascular disease, and cancer, are associated with low-grade chronic inflammation and poor dietary habits. Modulation of the inflammatory status through dietary components is a very appellative approach to fight these diseases and is supported by increasing evidence of natural and dietary components with strong anti-inflammatory activities. The consumption of bioactive lipids has a positive impact on preventing chronic inflammation and consequently NCD and AAD. Thus, new sources of bioactive lipids have been sought out. Microalgae are rich sources of bioactive lipids such as omega-6 and -3 polyunsaturated fatty acids (PUFA) and polar lipids with associated anti-inflammatory activity. PUFAs are enzymatically and non-enzymatically catalyzed to oxylipins and have a significant role in anti and pro-resolving inflammatory responses. Therefore, a large and rapidly growing body of research has been conducted in vivo and in vitro, investigating the potential anti-inflammatory activities of microalgae lipids. This review sought to summarize and critically analyze recent evidence of the anti-inflammatory potential of microalgae lipids and their possible use to prevent or mitigate chronic inflammation.

BACKGROUND: High visceral fat storage unbalance secretion inflammatory peptides, however diet plays an important role-protecting metabolism against chronic diseases inherent to this condition. OBJECTIVE: To assess obese diet quality and find association with inflammatory biomarkers. METHODS: aMED, a Food Quality Index, classified the inflammatory power of 26 obese men’s diet (aged: 48.1±5.1; BMI: 31.1±2.45). Pearson correlation coefficient associated diet quality in tertiles (1st as low, 2nd as average and 3 rd as high quality diet) with inflammatory variables (cytokines and waist circumference). RESULTS: The intake of anti-inflammatory food groups was significantly higher among tertiles (3rd >  2nd >  1st; P <  0.001). Adiponectin was lower in the 2nd tertile than in the 1st (P <  0.05). Whole cereal presented a positive correlation with TNF-alpha (p = 0.049), and a negative correlation with IL–15 (p = 0.002). Fish presented a positive correlation with IL–10 (p = 0.024), Resistin (p = 0.039) and PGE–2 (p = 0.001). These findings pointed to pro and anti-inflammatory responses. CONCLUSIONS: The method may need adjustments when used to assess obese food intake, since they don't usually meet the daily-recommended intake. Other lifestyles variables should be considered, which may affect the inflammatory status.

Patients with musculoskeletal diseases (MSDs) constitute a heavy burden on the society. Therefore, there is a constant search for safe and efficient methods for treatment of such conditions, in which inflammation underlies the pathogenetic process. Chronic back pain is associated with physical inactivity and other lifestyle factors, such as tobacco consumption, poor dietary habits, overweight, poor sleep quality, and uncontrollable stress. For example, obesity is associated with low-grade chronic systemic inflammation, and is, therefore, a significant risk factor for occurrence and chronicity of back pain. The patient's lifestyle may contribute to MSDs, including chronic MSDs associated with inflammation and decreased functional capacity, both independently or in combination with other risk factors. The most common drugs used for treatment of MSDs are the non-steroidal anti-inflammatory drugs (NSAIDs). However, taking into account the possible NSAID-induced adverse events, the physicians are constantly thinking about ways to reduce the risks. В vitamins (B1, B6 and B12) possess analgesic and anti-inflammatory effects, which are discussed in the paper. When used in combination with NSAIDs, particularly in combination of diclofenac with vitamins B1, B6 and B12, the B vitamins possess some other positive effects contributing to restoration of mobility, pain relief and functional recovery in patients with low back pain. Such combination (diclofenac + vitamins B1, B6 and B12) is represented on the Russian market by Neurodiclovit, the successful use of which is discussed in the case report.

Omega-3 rich diets have been shown to improve inflammatory status. However, in an ex vivo system of human blood cells, the efficacy of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) modulating lipid metabolism and cytokine response is attenuated in overweight subjects and shows high inter-individual variability. This suggests that obesity may be exerting a synergistic effect with genetic background disturbing the anti-inflammatory potential of omega-3 long-chain polyunsaturated fatty acids (PUFA). In the present work, a genetic score aiming to explore the risk associated to low grade inflammation and obesity (LGI-Ob) has been elaborated and assessed as a tool to contribute to discern population at risk for metabolic syndrome. Pro-inflammatory gene expression and cytokine production as a response to omega-3 were associated with LGI-Ob score; and lower anti-inflammatory effect of PUFA was observed in subjects with a high genetic score. Furthermore, overweight/obese individuals showed positive correlation of both plasma C-Reactive Protein and triglyceride/HDLc-index with LGI-Ob; and high LGI-Ob score was associated with greater hypertension (p = 0.047), Type 2 diabetes (p = 0.026), and metabolic risk (p = 0.021). The study shows that genetic variation can influence inflammation and omega-3 response, and that the LGI-Ob score could be a useful tool to classify subjects at inflammatory risk and more prone to suffer metabolic syndrome and associated metabolic disturbances.

Carotenoids are natural lipophilic pigments with substantial health benefits. Numerous studies have demonstrated the anti-inflammatory activities of carotenoids, especially toward lipopolysaccharide-induced inflammatory responses. As such, there are few reports on the evaluation and comparison of the anti-inflammatory activities of carotenoids against inflammation induced by other stimuli. In this study, we used pathogen-associated molecular patterns, proinflammatory cytokines, degenerated proteins, and chemical irritants as inflammatory inducers to evaluate the anti-inflammatory activities of eight different carotenoids. Each carotenoid showed characteristic anti-inflammatory activities; thus, we conducted a multivariate analysis to clarify the differences among them. Unsubstituted β-ring (i.e., provitamin A) and C8-keto structures of carotenoids were found to be crucial for their inhibitory effects on the activation of nuclear factor-kappa B and interferon regulatory factors, respectively. Furthermore, we found that β-carotene and echinenone treatment increased intracellular retinoid levels in monocytes and that the retinoids showed the similar activities to β-carotene and echinenone. Taken together, the intake of both provitamin A and C8-keto carotenoids (e.g., siphonaxanthin and fucoxanthin) might be effective in improving the inflammatory status of individuals. A multivariate analysis of anti-inflammatory activities is a useful method for characterizing anti-inflammatory compounds.

Aging is the consequence of a lifelong accumulation of stochastic damage to tissues and cellular components. Advancing age closely associates with elevated markers of innate immunity and low-grade chronic inflammation, probably reflecting steady increasing incidents of cellular and tissue damage over the life course. The DNA sensing cGAS-STING signaling pathway is activated by misplaced cytosolic self-DNA, which then initiates the innate immune responses. Here, we hypothesize that the stochastic release of various forms of DNA from the nucleus and mitochondria, e.g., because of DNA damage, altered nucleus integrity, and mitochondrial damage, can result in chronic activation of inflammatory responses that characterize the aging process. This cytosolic self-DNA-innate immunity axis may perturb tissue homeostasis and function that characterizes human aging and age-associated pathology. Proper techniques and experimental models are available to investigate this axis to develop therapeutic interventions.

Abstract Background. Today humanity is facing another infectious threat: a newly emerging virus SARS-CoV-2 causing COVID-19. It was already described that COVID-19 mortality among elderly people and people with such underlying conditions as obesity, cardiovascular diseases, cancer, chronic respiratory diseases, and diabetes s increased. Dysregulation of the immune responses vital for antiviral defense, which are typical for chronic inflammation, led us to a hypothesis that chronic inflammation is the main risk factor for increased susceptibility and mortality from COVID-19. Method. Based on the available information for 126 countries, statistical analysis to find out whether the difference in incidence and mortality within countries can be explained by the existing chronic inflammation among the countries population, was conducted. Results. A positive correlation between the percentage of people dying from chronic noncommunicable diseases and COVID-19 incidence (p<0.001) and mortality (p<0.001) within countries. Conclusion. The problem of COVID-19-caused high mortality rate may be a consequence of the high number of people having chronic low-grade inflammation as a precondition, and thus, one of the potential ways to reduce risk of morbidity and mortality is to focus on this widespread health problem, mainly occurring in developed countries and to take corresponding diagnostic, preventative, and treatment measures.

Abstract Background/Introduction Low-grade systemic chronic inflammation is a major risk factor for cardiometabolic diseases. Higher physical activity has athero- and cardioprotective effects, potentially through its anti-inflammatory properties. However, the relation between resting inflammatory status and cardiorespiratory fitness (CRF) in population-based settings remains to be elucidated. While previous research has shown inverse associations between CRF and high-sensitive C-reactive protein (hs-CRP) levels, relations with other inflammatory markers are not yet well examined. Purpose We assessed the relation between markers of CRF (i.e. maximal oxygen uptake [VO2peak], oxygen uptake at the anaerobic threshold [VO2@AT], oxygen pulse [O2HRmax] and maximal workload [max. Watt]) and hs-CRP as well as total white blood cell (WBC), monocyte, neutrophil, lymphocyte, eosinophil and basophil counts. Methods Data of the population-based cohort Study of Health in Pomerania (SHIP) was used (n=1,481; 51% male; age range 20–81 years). CRF was assessed using standardized cardio-pulmonary exercise testing (CPET) according to a modified Jones protocol. The Dimension Vista 500 analytical system was used to measure hs-CRP concentrations. Fluorescence-activated cell sorting was used to assess total as well as subpopulation WBC count. We excluded subjects with missing data, anti-rheumatic/steroid/anti-inflammatory medication as well as chronic inflammatory and hepatic diseases, gastritis, hepatitis infection, severe renal disease, chronic lung disease, asthma, chronic bronchitis, previous myocardial infarction, left ventricular ejection fraction <40% and previous cancer. Linear regression models, adjusted for age, sex, current smoking and lean-mass, were used to assess the relation between CPET and inflammatory parameters. Results A 14 ml/min (95%-confidence interval [CI] −23 to −6, p=0.004) lower VO2peak was associated with a one mg/L higher hs-CRP. A lower VO2peak was also related with a one Gpt/L greater WBC (β: −42. 95% CI: −55 to −27 ml/min, p<0.001) as well as neutrophil (β: −57, 95% CI: −77 to −36 ml/min, p<0.001), lymphocyte (β: −63, 95% CI: −107 to 19 ml/min, p=0.005) and monocyte count (β: −204, 95% CI: −360 to −47 ml/min, p=0.011). No significant associations were found for eosinophil and basophil count. Similar results were found for VO2@AT, O2HRmax and max. Watt. Conclusion Results suggest an inverse association between CRF and resting inflammatory status. Our non-significant findings with regards to eosinophils and basophils may be expected since these cell types are generally involved in type 2 immune responses related to allergic skin and airway inflammation as well as immunity against parasites. Overall, our results imply that potential biological mechanisms underlying the athero- and cardioprotective effects of high CRF may be related to lower chronic inflammation in fitter individuals.

Abstract Prostaglandins (PGs) are the major lipid mediators in animals and which are biosynthesized from arachidonic acid by the cyclooxygenases (COX-1 or COX-2) as the rate-limiting enzymes. Prostaglandin E2 (PGE2), which is the most abundantly detected PG in various tissues, exerts versatile physiological and pathological actions via four receptor subtypes (EP1–4). Non-steroidal anti-inflammatory drugs, such as aspirin and indomethacin, exert potent anti-inflammatory actions by the inhibition of COX activity and the resulting suppression of PG production. Therefore, PGE2 has been shown to exacerbate several inflammatory responses and immune diseases. Recently, studies using mice deficient in each PG receptor subtype have clarified the detailed mechanisms underlying PGE2-associated inflammation and autoimmune diseases involving each EP receptor. Here, we review the recent advances in our understanding of the roles of PGE2 receptors in the progression of acute and chronic inflammation and autoimmune diseases. PGE2 induces acute inflammation through mast cell activation via the EP3 receptor. PGE2 also induces chronic inflammation and various autoimmune diseases through T helper 1 (Th1)-cell differentiation, Th17-cell proliferation and IL-22 production from Th22 cells via the EP2 and EP4 receptors. The possibility of EP receptor-targeted drug development for the treatment of immune diseases is also discussed.

Low Grade Inflammation

Chronic low-grade inflammation associated with cardiovascular disease and type 2 diabetes (T2D) may be ameliorated with exercise and/or diet. High levels of physical activity and/or cardiorespiratory fitness are associated with reduced risk of low-grade inflammation. Both aerobic and resistance exercise have been found to improve inflammatory status, with the majority of evidence suggesting that aerobic exercise may have broader anti-inflammatory effects. In particular, aerobic exercise appears to improve the balance between pro- and anti-inflammatory markers. Improvement in inflammatory status is most likely to occur in persons with elevated levels of pro-inflammatory markers prior to intervention. A number of dietary factors, including fiber-rich foods, whole grains, fruits (especially berries), omega-3 fatty acids, antioxidant vitamins (eg, C and E), and certain trace minerals (eg, zinc) have been documented to reduce blood concentrations of inflammatory markers. Anti-inflammatory foods may also help mitigate the pro-inflammatory postprandial state that is particularly evident after ingestion of meals high in saturated fat. Intensive lifestyle interventions involving both exercise and diet appear to be most effective. For the most part, anti-inflammatory effects of exercise and diet are independent of weight loss. Thus overweight and obese men and women, who are most likely to have a pro-inflammatory profile, do not necessarily have to normalize body mass index to improve inflammatory status and reduce risk of type 2 diabetes and cardiovascular disease.

Anti Inflammatory

Inflammation is a stereotypical physiological response to infections and tissue injury; it initiates pathogen killing as well as tissue repair processes and helps to restore homeostasis at infected or damaged sites. Acute inflammatory reactions are usually self-limiting and resolve rapidly, due to the involvement of negative feedback mechanisms. Thus, regulated inflammatory responses are essential to remain healthy and maintain homeostasis. However, inflammatory responses that fail to regulate themselves can become chronic and contribute to the perpetuation and progression of disease. Characteristics typical of chronic inflammatory responses underlying the pathophysiology of several disorders include loss of barrier function, responsiveness to a normally benign stimulus, infiltration of inflammatory cells into compartments where they are not normally found in such high numbers, and overproduction of oxidants, cytokines, chemokines, eicosanoids and matrix metalloproteinases. The levels of these mediators amplify the inflammatory response, are destructive and contribute to the clinical symptoms. Various dietary components including long chain ω-3 fatty acids, antioxidant vitamins, plant flavonoids, prebiotics and probiotics have the potential to modulate predisposition to chronic inflammatory conditions and may have a role in their therapy. These components act through a variety of mechanisms including decreasing inflammatory mediator production through effects on cell signaling and gene expression (ω-3 fatty acids, vitamin E, plant flavonoids), reducing the production of damaging oxidants (vitamin E and other antioxidants), and promoting gut barrier function and anti-inflammatory responses (prebiotics and probiotics). However, in general really strong evidence of benefit to human health through anti-inflammatory actions is lacking for most of these dietary components. Thus, further studies addressing efficacy in humans linked to studies providing greater understanding of the mechanisms of action involved are required.
