Very-long chain omega-3 fatty acids (EPA and DHA) have anti-inflammatory properties that may help reduce morbidity and mortality from COVID-19 infection. We conducted a pilot study in 100 patients to test the hypothesis that RBC EPA+DHA levels (the Omega-3 Index, O3I) would be inversely associated with risk for death by analyzing the O3I in banked blood samples drawn at hospital admission. Fourteen patients died, one of 25 in quartile 4 (Q4) (O3I ≥5.7%) and 13 of 75 in Q1–3. After adjusting for age and sex, the odds ratio for death in patients with an O3I in Q4 vs Q1–3 was 0.25, p = 0.07. Although not meeting the classical criteria for statistical significance, this strong trend suggests that a relationship may indeed exist, but more well-powered studies are clearly needed.s…..

From Pauling’s theories to the present, considerable understanding has been acquired of both the physiological role of vitamin C and of the impact of vitamin C supplementation on the health. Although it is well known that a balanced diet which satisfies the daily intake of vitamin C positively affects the immune system and reduces susceptibility to infections, available data do not support the theory that oral vitamin C supplements boost immunity. No current clinical recommendations support the possibility of significantly decreasing the risk of respiratory infections by using high-dose supplements of vitamin C in a well-nourished general population. Only in restricted subgroups (e.g. athletes or the military) and in subjects with a low plasma vitamin C concentration a supplementation may be justified. Furthermore, in categories at high risk of infection (i.e. the obese, diabetics, the elderly, etc.) a vitamin C supplementation can modulate inflammation, with potential positive effects on immune response to infections…..

In recent years, viruses similar to those that cause serious disease in humans and other mammals have been detected in apparently healthy bats. These include filoviruses, paramyxoviruses, and coronaviruses that cause severe diseases such as Ebola virus disease, Marburg haemorrhagic fever and severe acute respiratory syndrome (SARS) in humans. The evolution of flight in bats seem to have selected for a unique set of antiviral immune responses that control virus propagation, while limiting self-damaging inflammatory responses. Read More

L’organismo produce una sostanza biochimica naturale con potere antivirale denominata PGA 1. Per combattere un’infezione è necessario che i suoi livelli siano il più possibile elevati. Infatti bassi livelli di PGA 1 favoriscono l’azione del virus influenzale e di tutti i tipi di virus. Poichè non si possono assumere integratori a base di PGA 1, l’unico modo di aumentarne i livelli è aumentare l’assunzione di Omega 3. Gli Omega 3 infatti…..

The epidemiology of influenza swarms with incongruities, incongruities exhaustively detailed by the late British epidemiologist, Edgar Hope-Simpson. He was the first to propose a parsimonious theory explaining why influenza is, as Gregg said, “seemingly unmindful of traditional infectious disease behavioral patterns.” Recent discoveries indicate vitamin D upregulates the endogenous antibiotics of innate immunity and suggest that the incongruities explored by Hope-Simpson may be secondary to the epidemiology of vitamin D deficiency. We identify…..

Genes required for SARS-CoV-2 entry into human cells, ACE2 and FURIN, were employed as baits to build genomic-guided molecular maps of upstream regulatory elements, their expression and functions in the human body, and pathophysiologically relevant cell types. Repressors and activators of the ACE2 and FURIN genes were identified based on the analyses of gene silencing and overexpression experiments as well as relevant transgenic mouse models. Panels of repressors (VDR; GATA5; SFTPC; HIF1a) and activators (HMGA2; INSIG1; RUNX1; HNF4a; JNK1/c-FOS) were then employed to identify existing drugs manifesting in their effects on gene expression signatures of potential coronavirus infection mitigation agents. Using this strategy, vitamin D and quercetin have been identified as putative 2019 coronavirus disease (COVID-19) mitigation agents. Quercetin has been identified as one of top-scoring candidate therapeutics in the supercomputer SUMMIT drug-docking screen and Gene Set Enrichment Analyses (GSEA) of expression profiling experiments (EPEs), indicating that highly structurally similar quercetin, luteolin, and eriodictyol could serve as scaffolds for the development of efficient inhibitors of SARS-CoV-2 infection. In agreement with this notion, quercetin alters the expression of 98 of 332 (30%) of human genes encoding protein targets of SARS-CoV-2, thus potentially interfering with functions of 23 of 27 (85%) of the SARS-CoV-2 viral proteins in human cells. Similarly, Vitamin D may interfere …..

The severe acute respiratory syndrome coronavirus 2 (Sars-CoV-2) global pandemic is a devastating event that is causing thousands of victims every day around the world. One of the main reasons of the great impact of coronavirus disease 2019 (COVID-19) on society is its unexpected spread, which has not allowed an adequate preparation. The scientific community is fighting against time for the production of a vaccine, but it is difficult to place a safe and effective product on the market as fast as the virus is spreading. Similarly, for drugs that can directly interfere with viral pathways, their production times are long, despite the great efforts made. For these reasons, we analyzed the possible role of non-pharmacological substances such as supplements, probiotics, and nutraceuticals in reducing the risk of Sars-CoV-2 infection or mitigating the symptoms of COVID-19. These substances could have numerous advantages in the current circumstances, are generally easily available, and have negligible side effects if administered at the already used and tested dosages. Large scientific evidence supports the benefits that some …..

In Gran Bretagna dopo che diversi studi epidemiologici hanno evidenziato che la vitamina D potrebbe avere un effetto preventivo contro il Covid. è partito un trial clinico di fase 3. Gli scienziati britannici stanno cercando dei volontari che prendano parte a una sperimentazione per provare se l’assunzione di vitamina D sia veramente protettiva nei confronti del SARS-CoV-2. I volontari riceveranno delle pillole per posta da prendere ogni giorno per sei mesi, se un test pungidito mostrerà carenze di questa vitamina. Lo studio, finanziato da Barts Charity, utilizzerà dosi più elevate di vitamina D rispetto ai normali integratori…… Read More

Background: Prognostic tools are required to guide clinical decision-making in COVID-19. Methods: We studied the relationship between the ratio of interleukin (IL)-6 to IL-10 and clinical outcome in 80 patients hospitalized for COVID-19, and created a simple 5-point linear score predictor of clinical outcome, the Dublin-Boston score. Clinical outcome was analysed as a three-level ordinal variable (“Improved”, “Unchanged”, or “Declined”). For both IL-6:IL-10 ratio and IL-6 alone, we associated clinical outcome with a) baseline biomarker levels, b) change in biomarker level from day 0 to day 2, c) change in biomarker from day 0 to day 4, and d) slope of biomarker change throughout the study…… Read More

Background: High levels of circulating proinflammatory cytokines are characteristic of inflammaging, a term coined to describe age-related chronic systemic inflammation involved in the etiology of many age-related disorders including nonhealing wounds. Some studies have shown that supplementing diets with n-3 polyunsaturated fatty acids (eicosapentaenoic acid [EPA] and docosahexaenoic acid [DHA]) lowers systemic levels of key proinflammatory cytokines associated with inflammaging. However, findings from the few studies that have focused exclusively on older adults are inconclusive. As such, the objective of this randomized controlled study was to test the effects of EPA+DHA therapy on circulating levels of proinflammatory cytokines in adults in middle to late adulthood. Adults in middle to late adulthood receiving EPA+DHA therapy demonstrated significantly greater reductions in circulating levels of proinflammatory cytokines compared with those receiving placebo therapy. EPA+DHA therapy may be an effective low-risk dietary intervention for assuaging the harmful effects of inflammaging….. Read More

This Review focuses on the resolution phase of inflammation with identification of specialized proresolving mediators (SPMs) that involve three separate biosynthetic and potent mediator families, which are defined using the first quantitative resolution indices to score this vital process. These are the resolvins, protectins, and maresins: bioactive metabolomes that each stimulate self-limited innate responses, enhance innate microbial killing and clearance, and are organ-protective. We briefly address biosynthesis of SPMs and their activation of endogenous resolution programs as terrain for new therapeutic approaches that are not, by definition, immunosuppressive, but rather new immunoresolvent therapies….

Millions of vulnerable people will be sent supplies of Vitamin D by the Government as evidence grows that it helps in the battle against Covid-19 infection. Care-home residents and people shielding because they suffer from conditions such as cancer will be sent enough supplies of the vitamin to last four months, with the first packages due to arrive early next month. The move comes after Health Secretary Matt Hancock decided he had to act fast in light of the emerging evidence about the benefits of Vitamin D….. Read More

Some natural products seem to be able to have an anti‐IL‐6 action, such as curcumin, resveratrol, and camellia sinensis (Theaceae)(Furst & Zundorf, 2014). Resveratrol (3, 4′, 5‐trans‐tri‐hydroxy‐stilbene) is a stilbene of plant origin belonging to the class of phytoalexins, molecules able to promote repair processes and defensive actions against biotic stresses, such as infections by pathogenic microorganisms, and abiotic stresses, such as oxidative ones. Polydatin (3,5,4′‐dihydroxystylbene‐3‐O‐β‐D‐glucopyranoside) is a glucoside of resveratrol characterized by conformational changes, which are reflected in changes in biological properties. It is more resistant than resveratrol to enzymatic oxidation and can penetrate the cell through an active transport mechanism. The biological activities of resveratrol and its glucosidic derivatives, such as polydatin, can be summarized as follows:….. Read More

Pulmonary fibrosis is a chronic and progressive lung disease which results in a loss of pulmonary function and eventually respiratory failure. Inflammation and epithelial mesenchymal transition (EMT) play important roles in the pathogenesis of pulmonary fibrosis. This study aimed to investigate the therapeutic effect of polydatin (PD) in bleomycin-induced pulmonary fibrosis. A bleomycin-induced pulmonary fibrosis animal model used SD rats. Morphological changes were analyzed by hematoxylin-eosin staining. RT-qPCR and western blot were used for the detection of the expression of TGF-β1, collagen I, collagen III, E-cadherin, fibronectin and the ratios of p-Smad2/Smad2, p-Smad3/Smad3. The concentrations of PICP, PIIINP, TNF-α, IL-1β, IL-6 and IL-17 were measured by enzyme linked immunosorbent assay (Elisa) assay….. Read More
