- summary: Regarding the given immunomodulatory effects of valproic acid, it has been suggested that the drug might provide benefits for ARDS due to the exaggerated immune response related to COVID-19. This study consolidates the findings showing the antiviral activity of valproic acid and gives hope for its potential usage in the COVID-19 pandemic.

- summary: AAT inhibition of ADAM17 also prevents shedding of ACE2 and hence may preserve ACE2 inhibition of bradykinin, reducing the ability of bradykinin to cause a capillary leak in COVID-19. Sixth, AAT inhibition of elastase can antagonize the formation of neutrophil extracellular traps (NETs), a complex extracellular structure comprised of neutrophil-derived DNA, histones, and proteases, and implicated in the immunothrombosis of COVID-19; indeed, AAT has been shown to change the shape and adherence of non-COVID-19-related NETs.

- summary: A sign of natural resistance to SARS-CoV-2? Dan Lipsker 1,2 , MD, PhD Since the start of the COVID-19 pandemic, epidemics of chilblains or chilblain-like acral lesions have been reported in the social media, the general press and the medical literature in Italy, Spain, the UK and France (1) (2) (3) (4) (5) . The great majority of the cases we observed and those reported in the literature share the following common features: -lesions were of sudden onset in young patients without a previous history of chilblains in most of them and they were not necessarily triggered by exposure to cold; -those young patients were otherwise asymptomatic or pauci-symptomatic and only a few had mild clinical signs compatible with COVID-19; -none of them had pneumonia or severe manifestations of COVID-19; -clinical signs of COVID-19 or contact with infected persons occurred a few days to one month before chilblains; -SARS-CoV-2 infection could be demonstrated by nasopharyngeal swab or by serology only in very limited number of patients.

- summary: 79 Supplemental glucosamine may likewise up-regulate the type 1 interferon responses to viruses, while exerting anti-inflammatory effects that render it protective in rodent models of sepsis and lung inflammation induced by LPS or cigarette smoke. Although PTX is known to have broad anti-inflammatory activity, it is employed primarily in the treatment of intermittent claudication; by lessening neutrophil activation, PTX renders these cells more distensible, so that they can more readily pass through narrow capillaries in affected legs.

- title: The influence of ABO blood groups on COVID-19 susceptibility and severity: a molecular hypothesis based on carbohydrate-carbohydrate interactions
- date: 2020-08-02
- words: 4621
- flesch: 29
- summary: Supported by an extensive bibliographic review highlighting (i) the mode of binding of SARS-CoV-2 to cell receptors, as well as (ii) the biochemical aspects of ABO blood group system and its association to infection and some circulatory conditions, we hypothesize that the influence of blood type on COVID-19 severity relies on the differential clustering of glycoproteins receptors to SARS-CoV-2 on host cell surface, induced by ABH antigens through carbohydrate-carbohydrate interactions with the glycan portions of these receptors, which could modulate virus binding to the target cell. In summary, this work proposes that the molecular mechanism underlying the influence of ABO blood groups on COVID-19 susceptibility and severity relies on carbohydrate-carbohydrate interactions between ABH antigens and sialoside glycans present on host cell receptors.

The notion of epidemics that normally have two peaks of new cases over time is widely accepted(3); although epidemiologists have not characterized this pattern as an established model.

Decreased immune system cells such as suppressed regulatory T cells, cytotoxic and helper T cells, natural killer cells, monocytes/macrophages and increased proinflammatory cytokines are the characteristic features.

- summary: Though it is intuitively tempting, on the basis of physiopathological common knowledge, to predict a greater risk of contracting the SARS-CoV-2 infection in tobacco smokers, an analysis of studies from various countries shows that hospitalized COVID-19 patients have a lower, and apparently inversely proportional, rate of current tobacco smoking, in comparison with the respective general population, although once the disease has developed meta-analyses suggest that smoking is associated with a worse prognosis Apart from nicotine or other chemicals contained in tobacco smoke, we propose that a single-stranded RNA virus that infects tobacco leaves, tobacco mosaic virus (TMV), might be implicated in this effect.

COVID-19: NAD + deficiency may predispose the aged, obese and type2 diabetics to mortality through its effect on SIRT1 activity We hypothesize that reduced Nicotinamide Adenine Dinucleotide (NAD + ) levels with consequent deficient activity of the NAD + dependent molecule SIRT1, which modulates cytokine production, may be the factor that predisposes the aged, obese, type 2 diabetics and other vulnerable groups to an increased mortality.

The mechanism of blood clotting is like a two-edged sword, wherein the case of severe external injury, clotting is very crucial for preventing the blood loss, whereas, in the case of internal blood vessels injury, it, unfortunately, leads to the formation of blood clots, causing vascular blockades and thrombosis, expanding to every organ leading to severe and fatal outcomes.

- summary: Therefore individuals with greater expression of tissue ACE, and consequently, greater production of Ang II, will present a decrease in tissue ACE2 and an increase in soluble ACE2 (systemic), due to greater activation of ADAM17 and ACE2 cleavage. Thus, due to higher levels of circulating ACE2, men may present a lower level of tissue ACE2, becoming more vulnerable to local SARS imbalance after SARS-Cov-2 infection.

- summary: Other than SARS-CoV-2 induced vascular endothelial dysfunction ACE2 mediated injury of liver tissue can also contribute to vascular thrombosis. Viral inclusion structures, an accumulation of inflammatory cells associated with endothelium, as well as apoptotic bodies were evidenced in vascular endothelial cells of multiple organs in 6 autopsied patients (28) , indicating for the widespread endothelial dysfunction as the etiology for the vascular thrombosis in COVID-19 (29) .
