-
reduced extracellular environment in the elderly and the increased susceptibility to Covid-19 infection
-
Redox signaling tightly modulates the inflammatory response and oxidative stress has been reported in acute Covid-19
-
People at high risk are the elderly, patients suffering from metabolic syndrome such as obesity, or those suffering from chronic diseases such as cancer or inflammation
-
COVID-19 patients with severe disease have higher levels of oxidative stress markers and lower antioxidant levels
-
oxidative stress can activate the NLRP3 inflammasome, which is a protein complex that plays a key role in the cytokine storm
-
inflammation leads to the formation of ROS and RNS, while redox iMeBalance results in cellular damage, which in turn triggers an inflammatory response
-
persistently elevated mtROS triggers endothelial dysfunction and inflammation, which results in a vicious loop involving ROS, inflammation, and mitochondrial dysfunction
-
IL-2 is highly up-regulated in Covid-19 patients [37], and IL-2 is known to significantly stimulate the generation of NO in patients
-
Elevated levels of lactate, a characteristic of the Warburg effect, were also reported in the high-risk Covid-19

-
characteristic of the Warburg effect is present in almost every disease and appears to be a central feature in most of the hallmarks of cancer
-
inflammation, mitochondrial dysfunction and increased lactate concentrations in the extracellular fluid
-
As the mitochondria are impaired, the infected cell cannot catabolize efficiently. It will release lactic acid in the blood stream
-
Striking similarities are seen between cancer, Alzheimer's disease and Covid-19, all related to the Warburg effect
-
Cancer, inflammation, Alzheimer's, and Parkinson's diseases share a common peculiarity, the inability of the cell to export entropy outside the body in the harmless form of heat
-
MEB relieves the Warburg effect [87], improves memory [77], is active in the treatment of depressive episodes [79,80] and reduces the importance of ischemic strokes
-
MEB relieves the Warburg effect [87], improves memory [77], is active in the treatment of depressive episodes [79,80] and reduces the importance of ischemic strokes
-
It has been shown that Covid-19-patients treated with MEB, have a significant reduction in hospital stay duration and mortality
-
MeB + can take a pair of electrons (of H atoms) and MeBH can release this pair easily, so that MeB is partially recycled like a catalyst
-
MeB acts as an electron bridge between a donor (FADH2, FMNH, NADH) and an acceptor (complex IV of ETC or oxygen itself)
-
As a coenzyme of pyruvate dehydrogenase (PDH), alpha-lipoic acid (ALA) initiates the formation of acetyl-CoA to feed the TCA cycle
-
ALA enhances the catabolism of carbon. cycle and therefore may reduce the Warburg effect and consequently, lactate production
-
Methylene Blue plays a similar role after the TCA cycle, by carrying electrons to complex IV of the electron transport chain
-
Drugs such as lipoic acid and MeB, which target the metabolism, decrease the redox shift by increasing catabolism

-
maturation, proliferation, and viability of T cells have all been shown to be upregulated by the presence of normal physiologic concentrations of vitamin C
-
vitamin C among healthy young adult males showed a significant increase in serum levels of IgA, IgG, and IgM
-
effects of high-dose vitamin C on cytokine levels in cancer patients, finding decreased amounts of the cytokines Interleukin-1 alpha (IL-1 alpha), IL-2, IL-8, and tumor necrosis factor-alpha (TNF-alpha) after high-dose vitamin C infusion
-
when vitamin C was supplemented with vitamin E in healthy adults, it increased the production of cytokines IL-1 beta and TNF-alpha
-
vitamin C acts to modulate the levels of cytokines to prevent them from fluctuating in either direction
-
human leukocytes, neutrophils, in particular, possess the ability to transport the oxidized form of vitamin C across its membrane to use as a defense mechanism against ROS produced during an immune response
-
Vitamin C also can recover other endogenous antioxidants in the body such as vitamin E and glutathione, returning them to their active state
-
can reduce harmful nitrogen-based compounds such as N-nitrosamines and nitrosamides, both of which are carcinogenic
-
subjects taking oral vitamin C supplementation saw a 60% to 90% reduction in oxidative stress compared to a placebo control
-
subjects infused with vitamin C alone had a 516% increase in glutathione levels compared to subjects not provided the 500 mg daily supplementation
-
Studies have demonstrated that those with low levels of vitamin C are at a significantly higher risk of respiratory infection compared to those with normal levels
-
viral cold duration was reduced by about 8% in adults and 13.5% in children using prophylactic daily doses of 200 mg of oral vitamin C
-
prophylactically supplementing vitamin C decreases the risk of infection with respiratory viruses such as the common cold
-
combined with probiotics, oral vitamin C supplementation showed a 33% decrease in the incidence of respiratory tract infections in preschool-age children [
-
high-dose oral supplementation of vitamin C managed to prevent or reduce symptoms if taken before or just after the onset of cold- or flu-like symptoms
-
improvements in oxygen saturation and decreased IL-6 levels (a marker of inflammation) in the treatment group compared to the control group
-
Patients with COVID-19 will likely also experience depletion in serum levels of vitamin C as a direct result of the upregulation of the immune system to combat the infection
-
Colunga et al. suggested that oral vitamin C can be combined with oral Quercetin, an antiviral flavonoid, to improve Quercetin’s ability to block viral membrane fusion of SARS-CoV-2
-
It appears vitamin C supplementation by itself does not provide a striking benefit in preventing COVID-19 infection for those without a deficiency
-
some evidence to support that prophylactic use of vitamin C helps reduce the severity of respiratory infection symptoms once a subject has already been infected
-
other studies were unable to find any definitive improvement concerning therapy with vitamin C
-
Fowler et al. aimed to see if a high-dose vitamin C infusion would benefit patients affected by ARDS, but they were unable to conclude that vitamin C infusion, compared to a placebo, could decrease vascular inflammation and damage in ARDS
-
in a sample of 67 COVID-19-positive ICU patients, 82% of them displayed plasma vitamin C levels below 0.4 mg/dL
-
continuous vitamin C infusion at a rate of 60 mg/kg/day for four days decreased the need for mechanical ventilation and vasopressor use but had no significant effect on overall mortality
-
Carr et al. suggested that high-dose IV vitamin C is most effective when treating sepsis as septic patients receiving the normal daily recommendations through diet still showed decreased vitamin C levels
-
High-dose IV vitamin C treatment has also been shown by Kakodkar et al. to decrease syndecan-1, an endothelial glycocalyx that contributes to mortality in septic patients
-
combined with hydrocortisone and thiamine, septic patients treated with 1.5 g of IV vitamin C every six hours showed a distinct decrease in their SOFA scores and none of the patients treated developed organ failure

-
surgery results in a serious wound that disrupts the structural barrier preventing the outspreading of cancer cells, change the properties of the cancer cells and stromal cells remaining in the tumor microenvironment, or impairs the host defense systems against cancers
-
After the primary tumor is surgically removed, the metastases can start to grow vigorously via neoangiogenesis because the circulating inhibitors disappear
-
infection and inflammation during the postoperative period have been reported to increase the risk of cancer recurrence in patients
-
Surgeons have long suspected that surgery, even if it is a necessary step in cancer treatment, facilitates cancer metastasis
-
Even externally palpitating tumors for diagnosis could increase the numbers of CTCs in skin cancer and breast cancer
-
In addition to glucocorticoids, during stimulation of the HPA axis, the catecholamine hormones epinephrine and norepinephrine are released from the adrenal medulla
-
NK cell suppression may be attributed to increased levels of catecholamines as well as glucocorticoids
-
In mice bearing a primary tumor, it was observed that the removal of the primary tumor facilitated the growth of highly vascularized metastases
-
second phase of tumor recurrence and metastasis, which are newly acquired events, rather than just outcomes of incomplete treatment.
-
formation of neutrophil extracellular traps (NETs), which are large extracellular complexes composed of chromatin and cytoplasmic/granular proteins1
-
Once activated, neutrophils produce intracellular precursors by using DNA, histones, and granular and cytoplasmic proteins and then spread the mature form of NETs out around themselves
-
neutrophil elastase, myeloperoxidase, cathepsin G, proteinase 3, lactoferrin, gelatinase, lysozyme C, calprotectin, neutrophil defensins, and cathelicidins
-
Neutrophils are the most abundant type of granulocytes, comprising 40–70% of all white blood cells
-
NETs are present in a variety of cancers, such as lung cancer, colon cancer, ovarian cancer, and leukemia
-
the proliferative cytokines TGFβ and IL-10 and the angiogenic factor VEGF are representative of neutrophil-derived tissue repair proteins.
-
when neutrophils are excessively stimulated, they produce excess NETs, thereby leading to pathological consequences
-
local invasion, intravasation into the blood or lymphatic vessels, escape from the immune system, anchoring to capillaries in target organs, extravasation into the organs, transformation from dormant cells to proliferating cells, colonization to micrometastases, and growth to macrometastases

NETs and platelets wrap CTCs, which protects them from attack by immune cells and shearing force by blood flow
-
After metastasizing to distant tissues, tumor cells are often found to remain dormant for a period of time and unexpectedly regrow late
-
NET-associated proteases NE and MMP-9 were found to be responsible for the reactivation of dormant cancer cells

The increased number of insulin receptors on the tumor cell, in comparison to the normal one, allows the before mentioned 2 factors to act predominantly
-
Increased permeability after the insulin effect on the cellular membrane results in increased intracellular quantity of antitumor agents
-
Insulin influences the intracellular metabolism of the tumor cell, which leads to increase of the number of cells in phase S, where they are with highly sensitive to specific chemotherapeutics.

-
pharmacological concentrations of AA can sensitize cancer cells to chemotherapy, enhancing its antineoplastic effect
-
synergistic effect with conventional chemotherapeutic drugs is a fact already reported, in various types of cancer, by numerous authors, namely in pancreatic (Espey et al., 2011), prostate (Gilloteaux et al., 2014), lung (Lee et al., 2017), breast (Kurbacher et al., 1996; Wu et al., 2017) and ovarian (Ma et al., 2014) cancers.
-
chemosensitizing effect of vitamin C has already been proven by several authors in various types of cancer
-
intravenous pharmacological concentrations, may not only potentiate the effects of conventional chemotherapy, but also improve the quality of life of cancer patients
-
Combined treatment induced a reduction of 11.5% and 43% in cell viability compared with AA or Iri therapies, respectively, emphasizing the synergistic effect
-
cytotoxic effect occurred with treatment with Iri alone, but also this effect was further potentiated by the presence of AA.
-
association of AA with Oxa showed very promising results, considering that a synergistic effect was demonstrated, in almost all conditions
-
AA and Oxa seem to act synergistically by the activation of the intrinsic pathway of apoptosis, translated on the statistically significant increase of the ratio between BAX and BCL-2 proteins, which in turn is associated with a decrease of Δψm
-
Previous results obtained by our group showed that AA mediates reactive oxygen species (ROS) formation capable of irreparably damaging DNA
