Spirulina platensis from Nomayos: a potential health food for the management of COVID-19 infection

The proteins (37%), carbohydrates (24.4%) and lipids (30.1%) contents of S. platensis from Nomayos provide the body with its structural and energy needs for about 518.8 Kcal per 100g of spirulina. Polyphenols (56.4 mEq. QE / g ES.), flavanols (13.2 mEq. QE / g ES.) flavonoids (21.2 mEq. QE / g ES.), carotenoids (3, 8%) and phycocyanin (16.15%) is responsible of its antioxidant capacities (7.5 + 0.33 mg eq. Vit C/g ES) and for a significant decrease in malondialdehyde MDA (< 0.001) concentration. Zinc (25 mG/Kg), Iron (256 mG/Kg), Selenium (1.24 mG/Kg), Manganese (23mG/Kg) and Copper (28.95 mG/Kg) reinforce this antioxidant power because they are cofactors of enzymes (Superoxide dismutase, Peroxidase, Catalase) which ensure the fight against free radicals. The presence of phycocyanin is an asset for the anti-inflammatory action. The significant decrease in IL-8 (p < 0.001) and TNF alpha (p < 0.04) levels confirms this property. On the other hand, the nonsignificant increase in Il-6 (1.56 to 2.18 pg/m;p > 0.05) would be partly responsible for the rise in CD4 levels (p < 0.001) and the reduction in viral load in immune deficiency patients (p = 0.000) supplemented with spirulina. In conclusion, S. platensis from Nomayos by its antioxidant, anti-inflammatory and immuno-stimulatory properties would be a good supplement food for subjects at risk of developing severe forms of COVID-19.

Protective effects of vitamin D3 (cholecalciferol) on vancomycin-induced oxidative nephrotoxic damage in rats.

CONTEXT: Vancomycin (VCM), an important antibiotic against refractory infections, has been used to treat secondary infections in severe COVID-19 patients. Regrettably, VCM treatment has been associated with nephrotoxicity. Vitamin D3 can prevent nephrotoxicity through its antioxidant effect. OBJECTIVE: This study tests the antioxidant effect of vitamin D3 in the prevention of VCM-induced nephrotoxicity. MATERIALS AND METHODS: Wistar Albino rats (21) were randomly divided into 3 groups: (A) control; (B) VCM 300 mg/kg daily for 1 week; and (C) VCM plus vitamin D3 500 IU/kg daily for 2 weeks. All the rats were sacrificed and serum was separated to determine kidney function parameters. Their kidneys were also dissected for histological examination and for oxidative stress markers. RESULTS: Lipid peroxidation, creatinine, and urea levels decreased significantly (p < 0.0001) in the vitamin D3-treated group (14.46, 84.11, 36.17%, respectively) compared to the VCM group that was given VCM (MIC<2 µg/mL) only. A significant increase was observed in superoxide dismutase levels in the vitamin D3-treated group (p < 0.05) compared to rats without treatment. Furthermore, kidney histopathology of the rats treated with vitamin D3 showed that dilatation, vacuolization and necrosis tubules decreased significantly (p < 0.05) compared with those in the VCM group. Glomerular injury, hyaline dystrophy, and inflammation improved significantly in the vitamin D3 group (p < 0.001, p < 0.05, p < 0.05, respectively) compared with the VCM group. DISCUSSION AND CONCLUSIONS: Vitamin D3 can prevent VCM nephrotoxicity. Therefore, the appropriate dose of this vitamin must be determined, especially for those infected with COVID-19 and receiving VCM, to manage their secondary infections.

The possibilities of using the effects of ozone therapy in neurology

OBJECTIVES: The beneficial effects of ozone therapy consist mainly of the promotion of blood circulation: peripheral and central ischemia, immunomodulatory effect, energy boost, regenerative and reparative properties, and correction of chronic oxidative stress. Ozone therapy increases interest in new neuroprotective strategies that may represent therapeutic targets for minimizing the effects of oxidative stress. METHOD(S): The overview examines the latest literature in neurological pathologies treated with ozone therapy as well as our own experience with ozone therapy. The effectiveness of treatments is connected to the ability of ozone therapy to reactivate the antioxidant system to address oxidative stress for chronic neurodegenerative diseases, strokes, and other pathologies. Application options include large and small autohemotherapy, intramuscular application, intra-articular, intradiscal, paravertebral and epidural, non-invasive rectal, transdermal, mucosal, or ozonated oils and ointments. The combination of different types of ozone therapy stimulates the benefits of the effects of ozone. RESULT(S): Clinical studies on O2-O3 therapy have been shown to be efficient in the treatment of neurological degenerative disorders, multiple sclerosis, cardiovascular, peripheral vascular, orthopedic, gastrointestinal and genitourinary pathologies, fibromyalgia, skin diseases/wound healing, diabetes/ulcers, infectious diseases, and lung diseases, including the pandemic disease caused by the COVID-19 coronavirus. CONCLUSION(S): Ozone therapy is a relatively fast administration of ozone gas. When the correct dose is administered, no side effects occur. Further clinical and experimental studies will be needed to determine the optimal administration schedule and to evaluate the combination of ozone therapy with other therapies to increase the effectiveness of treatment.Copyright © 2021 Neuroendocrinology Letters.

Superoxide Dismutase Inhibitors against Malaria, Leishmaniasis, and Chagas Disease: Systematic Review.

INTRODUCTION: Diseases caused by protozoa are one of the leading causes of death worldwide, especially in tropical regions such as Brazil. Chagas disease, leishmaniasis, and malaria are responsible for around 234 million cases and more than 400,000 deaths worldwide. Despite this scenario, drugs for these diseases have several limitations, which justifies the search for new treatments. Iron superoxide dismutase is a promising target for the drug design to treat patients with these diseases. It is a validated target and protects against oxidative stress. AIM: Thus, this systematic review aimed to synthesize evidence on the importance of superoxide dismutase in the drug design to treat patients with this protozoosis. METHODS: A search was performed for in vitro and in vivo studies, without publication and language restrictions, in MEDLINE (PubMed), LILACS (BVS), Science Direct, and EMBASE (Elsevier). Studies that pointed to the relationship between the reduction or increase in superoxide dismutase activity and the diseases were included. 23 studies were selected for the qualitative synthesis. RESULTS: The results showed that the inhibition or reduction of the enzyme activity decreases the degree of infection and reinfection and improves the results in treating these diseases. In contrast, the increase in activity caused a high degree of survival and resistance of the parasites. CONCLUSION: However, the overall quality of evidence is low and more studies with methodological rigor are provided.

TGFB1, FOXO1, and COMP Genes Expression in Blood of Patients with Osteoarthritis after SARS-CoV2 Infection.

Abstract-Nowadays the possible influence of the coronavirus infection on cartilage degeneration and synovial membrane inflammation during chronic joint pathology-osteoarthritis-remains largely unelucidated. The aim of the presented work is to analyze the TGFB1, FOXO1, and COMP gene expression and free radical generation intensity in blood of patients suffering from osteoarthritis after beating the SARS-CoV2 infection. The work was carried out using molecular genetics and biochemistry methods. The decrease of the TGFB1 and FOXO1 expression level was shown to be more evident in the osteoarthritis patients after COVID-19 if compared to the group with knee osteoarthritis during simultaneous and more prominent diminishing of both superoxide dismutase and catalase activity (possibly indicating cell redox state disruption and TGF- P1-FOXO1 signaling attenuation) in patients with osteoarthritis after SARS-CoV2 disease. At the same time, the more prominent decrease of COMP gene expression level was demonstrated in patients with osteoarthritis after COVID-19 compared to the group with knee osteoarthritis and more intense increase of the COMP concentration in patients with osteoarthritis after the SARS-CoV2 infection was revealed. These data indicate more significant activation of cell destructive processes after the infection as well as further pathology progression.

A Review: Zinc as an Antivirus Alternative Treatment for Herpes Simplex Virus Infection

This study aimed to review zinc's effectiveness as an antivirus in treating herpes simplex virus infection. The authors use international journals published from 2000-2022, and use search engines such as Google Scholar, PubMed, and Science Direct with the keywords "zinc and herpes simplex virus". The herpes simplex virus that often causes symptoms in humans are HSV type 1 and type 2. The lesions appear as vesicles which then rupture into ulcers. Zinc is one of the most abundant nutrients or metals in the human body besides iron. Studies about the effects of zinc on HSV have shown that it has the function of inhibiting the viral life cycle. HSV attaches to the host cells to replicate and synthesize new viral proteins. Zinc can inhibit this process by depositing on the surface of the virion and inactivating the enzymatic function which is required for the attachment to the host cell, disrupting the surface glycoprotein of the viral membrane so it could not adhere and carry out the next life cycle, it can also inhibit the function of DNA polymerase that works for viral replication in the host cell. This article showed that zinc has effectiveness as an antivirus against the herpes simplex virus, therefore, patients infected with HSV can be treated with zinc as an alternative to an antivirus drug.Copyright © 2022 The Authors.

Ascorbic Acid vs Calcitriol in Influencing Monocyte Chemoattractant Protein-1, Nitric Oxide, Superoxide Dismutase, as Markers of Endothelial Dysfunction: In Vivo Study in Atherosclerosis Rat Model.

Introduction: Ascorbic acid and calcitriol were frequently utilized in conjunction as therapy during the COVID-19 pandemic, and individuals with minor symptoms had notable improvements. There have been a few studies, often with conflicting findings, that examine the use of them for endothelium restoration and numerous clinical trial studies that failed to establish the efficacy. The aim of this study was to find the efficacy of ascorbic acid compared to calcitriol on the inflammatory markers monocyte chemoattractant protein-1 (MCP-1), nitric oxide (NO), and superoxide dismutase (SOD), as protective agents which play an important role in the early stages of atherosclerosis formation. This study was an experimental in vivo study. Methods: The total of 24 male Rattus norvegicus strain Wistar rats were divided into 4 groups, namely: control/normal group (N), atherosclerosis group (DL) given atherogenic diet, atherosclerosis group given atherogenic diet and ascorbic acid (DLC), and atherosclerosis group given atherogenic diet and calcitriol (DLD) treatment for 30 days. Results: Ascorbic acid and calcitriol treatment was significantly effective (P<0.05) in lowering expression of MCP-1 and increasing NO and SOD level. Calcitriol was superior to ascorbic acid in increasing SOD (P<0.05). There was no significant difference between ascorbic acid and calcitriol in decreasing MCP-1 and increasing NO (P>0.05). Discussion: Both treatments could reduce MCP-1, and increase NO and SOD by increasing antioxidants. In this study calcitriol was superior to ascorbic acid in increasing SOD, but not NO and decreasing MCP-1. According to the theory, it was found that calcitriol through nuclear factor erythroid 2-related factor 2 (Nrf2) causes a direct increase in the amount of SOD. Nrf2 is an emerging regulator of cellular resistance to oxidants. Conclusion: Ascorbic acid and calcitriol treatment was able to reduce MCP-1 and increase NO and SOD in atherosclerosis rat. Calcitriol was significantly superior in increasing SOD levels compared to ascorbic acid.

The level of nitric oxide and arginase activity in patients with arterial hypertension and diabetes mellitus during COVID-19

The aim of this study was to assess the level of nitric oxide production and arginase activity in patients with arterial hypertension and type II diabetes mellitus during infection with SarS-CoV-2. The study groups included patients with arterial hypertension, patients with arterial hypertension combined with a severe course of COVID-19 and patients who, in addition to arterial hypertension and COVID-19, were suffering from type II diabetes mellitus. The volunteers without any clinical signs of diseases and normal blood pressure formed the control group. It has been established that arterial hypertension, combined with COVID-19 occurs along with reduced L-arginine, nitric oxide, superoxide dismutase activity and increased arginase activity. At the same time, the presence of arterial hypertension in patients with diabetes and coronavirus disease is accom-panied by a decline in the content of L-arginine and arginase activity. Our study's results may help scientists find new pharmacological targets in the future treatment of coronavirus disease and comorbid disorders. © 2022, Palladin Institute of Biochemistry of the NASU.

The Efficacy of Methylprednisolone in Clinical Manifestations, Inflammatory Biomarkers, and Antioxidant Changes in the COVID-19 Patients

Background: The application of methylprednisolone in ARDS patients has led to a sustained reduction in inflammatory plasma cytokines and chemokines and has recently been used in the treatment of patients with SARS-CoV-2 infection. Objectives: In this study, the effect of methylprednisolone on clinical symptoms and antioxidant changes of patients with COVID-19 has been investigated. Methods: In the present study, patients with moderate to severe COVID-19 who required hospitalization were entered into the study phase. Then, in addition to standard treatment, patients received methylprednisolone at a dose of 250 mg intravenously over three days. Necessary evaluations include analysis of arterial blood gases, pulse oximetry, monitoring of patient clinical signs, examination of inflammatory biomarkers, and also receiving 10 cc of peripheral blood samples to check for antioxidant changes, at the beginning of the study, after 24 hours, and 72 hours after receiving methylprednisolone was on the agenda. Results: Changes in fever, superoxide dismutase (SOD, Glutathione-S-Transferase (GST, the ferric reducing ability of plasma (FRAP, malondialdehyde (MDA, Nitric oxide, Ferritin, and TNF-α before treatment and 72 hours after treatment were significantly different between the two stages (P < 0.05). Conclusions: The use of methylprednisolone improves the balance of antioxidants and immunological factors in patients with COVID-19 and thus improves some clinical indicators in these patients.

The Impact of COVID-19 Spike Protein on Retinal Microvascular Environment

Purpose : Background: Despite being primarily a respiratory disease, COVID-19 can lead to non-respiratory complications, including myocardial infarction and acute ischemic stroke. Moreover, COVID-19 spike protein (SP) was reported in the retina of deceased patients with COVID-19. Retinal microvascular abnormalities as loss of microvasculature and distinct thinning of the microcapillaries were reported in patients who recovered from COVID-19. We are still in the midst of the COVID-19 pandemic, with more deaths and cases every day. Therefore investigating the impact of COVID-19 on the retinal neurovascular environment and the long-term effect of this virus on vision is of great interest. Purpose: To study the contribution of COVID-19 SP to retinal inflammation and vascular death. Methods : Methods: COVID-19 SP, a highly glycosylated protein that allows the virus to penetrate the cell and cause infection, was injected intravitreally in 6-8 weeks global h-ACE2 knock-in mice and wild-type mice. Mice were sacrificed after 14 days, then vascular cell death and inflammation were evaluated by the presence of acellular capillaries and the expression of inflammatory and apoptotic markers. To complement our in-vivo studies, Human Microvascular Endothelial Cells (HMEC) were treated with 100 nM COVID-19 SP for 48 hours. The expression of inflammatory and apoptotic markers was assessed by PCR western blot. Results : Results: Our results showed that HMEC exposed to COVID-19 SP for 48 hours displayed an increase in inflammatory and apoptotic markers expression including TNF-α, IL-1β, IL-6, and cleaved caspase-3 compared to control conditions. Additionally, COVID-19 SP enhanced the oxidative stress in HMEC, evident by the increase in nitro-tyrosine formation, superoxide dismutase, and NADPH oxidase complex 1 (NOX1 and NOX5) expression. The in-vivo findings came in agreement with our in-vitro studies. We found that intravitreal injection of the COVID-19 SP-induced 1) strong activation of the retinal glial cells, assessed by GFAP radial staining, and 2) increased vascular death, assessed by acellular capillaries formation 14 days after the injection. Conclusions : Conclusions: Our findings highlight the possible role of COVID-19 SP in inducing retinal inflammation and vascular death. Further studies are required to reveal the impact of COVID-19 SP on visual acuity and the possibility of causing visual impairment using various animal models.

Oxidative Stress Markers and Sperm DNA Fragmentation in Men Recovered from COVID-19.

SARS-CoV-2 negatively affects semen characteristics, impairs various biochemical processes in seminal fluid and within spermatogenic cells ultimately leading to male fertility decline. However, the distinct mechanisms, in particular, the role of oxidative stress on the consequences of coronavirus infection, have not been well investigated, which is the purpose of the present study. The standard semen parameters, its pro- and antioxidant system state, as well as the level of sperm DNA fragmentation, were assessed in 17 semen samples of men five months after the coronavirus infection and in 22 age-matched control patients. We determined that the DNA fragmentation rate negatively correlated with the period after coronavirus recovery, as well as seminal fluid superoxide dismutase activity and uric acid level. It was demonstrated that COVID-19 is not always associated with increased DNA fragmentation, allowing them to be considered as two independent factors. Thus, the most significant changes were noted in the samples of men after COVID-19 and abnormal TUNEL results: increased round cell number, decreased seminal fluid's nitrotyrosine level, and total antioxidant capacity and Zn, as well as an increased 8-hydroxy-2'-deoxyguanosine level within spermatozoa. The data obtained indicate that increased DNA fragmentation and diminished semen quality in men can be the result of an imbalance in semen pro- and antioxidant components after COVID-19.

Effect of a diet based on Iranian traditional medicine on inflammatory markers and clinical outcomes in COVID-19 patients: A double-blind, randomized, controlled trial.

Introduction: SARS-CoV-2 causes severe acute respiratory syndrome prompting worldwide demand for new antiviral treatments and supportive care for organ failure caused by this life-threatening virus. This study aimed to help develop a new Traditional Persian Medicine (TPM) -based drug and assess its efficacy and safety in COVID-19 patients with major symptoms. Methods: In February 2022, a randomized clinical trial was conducted among 160 patients with a confirmed diagnosis of COVID-19 admitted to Emam Reza (AJA) Hospital in Tehran, Iran. During their hospitalization, the intervention group received a treatment protocol approved by Iran's Ministry of Health and Medical Education (MOHME), consisting of an Iranian regimen, Ficus carica; Vitis vinifera, Safflower, Cicer arietinum, Descurainiasophia seeds, Ziziphus jujuba, chicken soup, barley soup, rose water, saffron, and cinnamon spices. All patients were compared in terms of demographics, clinical, and laboratory variables. Results: One hundred and sixty COVID-19 patients were divided into two groups: intervention and control. In baseline characteristics, there was no significant difference between the intervention and control groups (p>0.05). Using SPSS software version 22, statistical analysis revealed a significant difference in four symptoms: myalgia, weakness, headache, and cough (p<0.05). During the 5-day treatment period, the control group had significantly lower C-reactive protein (p<0.05). Conclusion: While more research with a larger sample size is needed, the proposed combination appears to be effective in the treatment of symptoms as well as inflammatory biomarkers such as C-reactive protein in COVID-19 patients.Iranian registry of clinical trials (IRCT) IRCT20220227054140N1.

Superoxide Dismutase Activity in Male and Female Patients of Different Age with Moderate COVID-19.

The study involved 271 patients (132 men and 139 women) with moderate COVID-19. Superoxide dismutase (SOD) activity in erythrocytes was measured spectrophotometrically. In total group of patients (divided into age groups of 18-35, 36-45, 46-60, and 61-90 years), higher SOD activity was found in the 18-35 age group in comparison with the groups 46-60 years (p<0.01) and 61-90 years (p<0.05). Then, the groups were additionally divided by sex. In men, no differences in enzyme activity were found between the age groups. In women of early reproductive age, SOD activity was higher than in groups 36-45, 46-60, and 61-90 years. The sex differences consisted in higher SOD activity in women aged 18-35 years in comparison with men of this age. These data should be taken into account when choosing the tactics of therapy for patients with moderate COVID-19 course.

Study to estimate levels of oxidative stress biomarkers in long COVID patients

Background: We estimated levels of oxidative stress biomarkers (Lipid peroxidation (LPO) via Malondialdehyde MDA concentration , Superoxide dismutase (SOD), Glutathione Reductase (GR) and Total antioxidant activity (TAA) in patients who were symptomatic beyond 4 weeks of COVID infection. Methods: It's a single centre, hospital based case control study in which levels of oxidative stress biomarkers in 40 Long COVID patients and 40 healthy controls were compared and analysed with their clinico-radiological profile. Results: 1. Lipid peroxidation (MDA) was significantly higher (1155.9 ± 204.82nmole/ml) in Long COVID patients as compared to control (715.5 ± 85.51nmole/ml) (p value 0.0405) 2. SOD in Long COVID patients was lower (18.05 ± 2.83 unit/mg) as compared to control (27.36 ± 2.18 unit/ mg) (p value 0.0096) 3. GR was reduced in Long COVID patients (10.2 ± 1.26 unit/min/mg of protein) as compared to control (15.7 ± 1.42 unit/min/mg of protein) (p value 0.0356) 4. TAA was also moderated in Long COVID patients (94.61 ± 16.40mM) as compared to control (241.64 ± 12.95mM) , (p value 0.0486) 5. LPO was directly and remaining markers were inversely proportional to the Severity of COVID and Xray Severity score 6. The patients with added comorbidities showed even higher oxidative stress than those with no comorbidities (p value 0.05) 7. Lipid peroxidation was significantly high in patients who developed neurological sequelae after COVID infection (p value 0.0083). Conclusion: A subset of patients develop a sequelae to COVID infection and in those patients oxidative stress plays a major role.
