Abstract The COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected over 100 million people causing over 2.4 million deaths over the world, and it is still expanding. There is an urgent need for targeted and effective COVID-19 treatments which has put great pressure on researchers across the world for developing effective drugs. This paper reviews the possibility of using Recombinant Bacterial ACE2 Receptors -Like Enzyme of B38-CAP to treat SARS-CoV-2 based on the intracellular mechanism of SARS-CoV-2 transmission and consequences caused. Angiotensin-converting enzyme 2 (ACE2) plays a key role in cardiovascular physiology and pathology, and it's being currently being investigated as a potential covid-19 and acute lung failure treatment through several clinical trials.. The SARS-CoV2 binding site was identified as ACE2, a part of the RAAS, which is known to protect the lung from injuries. it has been postulated that SARS-CoV-2 binding to ACE2 may attenuate residual ACE2 activity, skewing the ACE/ACE2 balance to a state of heightened angiotensin II activity leading to inflammatory and oxidative organ damage, as well as pulmonary vasoconstriction, which can lead to acute lung injury.. Therefore, treatment with recombinant soluble ACE2 protein and drugs that up regulate ACE2 may alleviate pulmonary complication. In animal models including heart failure, acute lung injury, and diabetic nephropathy, recombinant human ACE2 protein (rhACE2), which is devoid of its membrane-anchored domain thus soluble, has been shown to have beneficial effects. Despite its positive effects, rhACE2 is a glycosylated protein, which necessitates a time- and cost-intensive protein expression system using mammalian or insect cells, which may be inconvenient in drug production and medical economics. Moreover, we hypothesis that treating COVID-19 patients with recombinant soluble ACE2 protein may induce autoantibodies and T cells to cellular ACE2.Furthermore, rhACE2 may interact with spike protein based vaccine and worsen its effect . These autoantibodies may generated by enforced presentation of the soluble Angiotensin-converting enzyme 2 (ACE2) protein in a complex with COVID-19 Spike protein in fragment crystallizable (FC) Receptor positive Antigen Presenting Cells in the blood The development of autoantibodies might make injury and damage to the host epithelial cells and hamper their ACE2 dependent function in lungs, intestine and testes which express ACE2. In addition to inducing platelet aggregation and thrombosis . Although it has been stated that immune response associated with the chronic infusion of rhACE2 resulting in the degradation of rhACE226, this was not the case with B38-CAP; no antibodies against B38-CAP were detected in the serum of mice infused with B38-CAP for two weeks... In this case we suggest that bacterial engineering could be used to develop better protein drugs for COVID-19 treatment... B38-CAP is an ACE2-like enzyme derived from bacteria that reduces hypertension and cardiac dysfunction. Angiotensin-converting enzyme 2 (ACE2) plays a key role in cardiovascular physiology and pathology, and it is currently being studied in clinical trials to treat acute lung failure. In mice, B38-CAP treatment prevented angiotensin II-induced hypertension, cardiac hypertrophy, and fibrosis. B38-CAP is an ACE2-like enzyme derived from bacteria, demonstrating that evolution has shaped a bacterial carboxypeptidase (B38-CAP) to a human ACE2-like enzyme. As a result, we think that treating COVID-19-infected patients with Bacterial ACE2 like enzymes, rather than human ACE2, may be preferable because it will perform the same role as human ACE2 and may not be recognized by COVID-19 spike protein Keywords: COVID 2019 ,Infection, B38-CAP , Bacterial ACE2 receptors -like enzyme , rhACE226.

Acute Bacterial Skin and Skin Structure Infection (ABSSSI)Non-healing Wound

This is a randomized study to compare the safety and efficacy of a single dose of up to 2 grams of cefazolin administered using a new drug delivery method called Ultrasonic Drug Delivery (UDD), combined with standard of care (SOC) antibiotic therapy, oral or IV, compared to standard of care (SOC) antibiotic therapy alone, in treating chronic wounds with skin and soft tissue infection, containing gram-positive pathogens, in lower extremities.

Probiotic Supplementation in the Dysbiosis of Bowel Preparation

Microbial ColonizationIrritable Bowel Syndrome1 more

Significant changes in gut microbiota was noted after the high-volume bowel preparation with PEG before colonoscopy. The dynamic changes were found to be short-term. However, the perturbation pattern of gut microbiota found after bowel preparation may link to metabolic syndrome and obesity. No study had investigated the supplementation of probiotic in this dynamic situation before. Here we proposed this study to fulfill the knowledge gap and also inquiry on the potential therapeutic strategy.1.To test the hypothesis of probiotic supplementation after bowel preparation alters the composition of gut microbiota in a short-term and long-term manner.2.To test the hypothesis of GI tract associated symptoms affected by probiotic supplementation after bowel preparation. 3. To test the hypothesis of clinical events, especially parameters of metabolic syndrome affected by probiotic supplementation after bowel preparation.

Use of Hypochlorous Acid as Prophylaxis in Health Personnel at High Risk of Infection by SARS-CoV...

SARS-CoV InfectionCovid191 more

The pandemic caused by SARS-CoV-2 is a global emergency present in 6 continents including 66 countries, incurring a shortage of effective and safe therapeutic alternatives that can contribute to reducing the risk of contamination, as well as helping to reduce the viral load of the positive patient. This requires a coordinated, effective and immediate action on the part of governments, companies, academic entities and even at the individual level. In the search for new therapeutic and prevention alternatives, the application of hypochlorous acid (HClO) to the nasal mucosa is proposed, a broad-spectrum and fast-acting antimicrobial solution, whose safety has been proven in preclinical trials. The efficacy of HClO has been tested against enveloped and non-enveloped viruses, reducing virus particles without affecting human cells. This solution could contribute to reducing the viral load and the risk of contamination of patients and professionals. This could have an impact on controlling the COVID-19 pandemic.

Clazakizumab vs. Placebo - COVID-19 Infection

COVID-19 Infection

The purpose of this study is to investigate the effectiveness and safety of treatment with clazakizumab compared to a placebo (inactive substance). We are proposing to try this drug to treat coronavirus disease 2019 (COVID-19) infection. Patients with COVID-19 infection have been shown to have increases in certain inflammatory processes. Clazakizumab is an antibody (immune system protein) that blocks certain inflammatory processes. The treatment plan is to attempt to inhibit or block these inflammatory processes in order to try to limit the damage COVID-19 causes to the lungs.
