Efficacy of Aerosol Combination Therapy of 13 Cis Retinoic Acid and Captopril for Treating Covid-19...

Covid19

Efficacy of Aerosol Combination Therapy of 13 Cis Retinoic Acid and Captopril for Treating Covid-19 Patients Via Indirect Inhibition of Transmembrane Protease, Serine 2 (TMPRSS2) Severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) has infected over 20,000,000 people causing over 700,000 deaths. It has no currently approved treatments.Airborne SARS-CoV-2 infections in humans initiate from the virus entering nasal and airway epithelial cells through binding to angiotensin-converting enzyme 2 (ACE2). Transmembrane protease, serine 2 (TMPRSS2), a cellular protease that activates the SARS-CoV-2 spike protein, colocalizes with ACE2 and can prime SARS-CoV-2 fusion directly at the plasma membrane. Transmembrane protease, serine 2 (TMPRSS2) is an androgen receptor signaling target gene and an androgen-regulated cell-surface serine protease expressed predominantly in prostate and lung epithelial cell. TMPRSS2 is normally expressed several folds higher in the prostate relative to any other human tissue, though the normal physiological function(s) remains unknown. A study found that dihydrotestosterone (DHT) s a potent activator of TMPRSS2.On the other hand, Feily et al noted that low-dose isotretinoin (0.5 mg/kg/day for 15-20 weeks) in PCO patients with moderate to severe nodulocystic acne resulted in significant decreases in levels of serum total testosterone, prolactin, and dihydrotestosterone A study demonstrated that 13- cis -Retinoic acid competitively and reversibly inhibits dihydrotestosterone. Therefore, we suggest that 13- cis -Retinoic acid will downregulate TMPRSS2 expression thorough temporary preventing the effect of dihydrotestosterone (DHT) on the activation of TMPRSS2 gene expression. ACE inhibitors and ARBs are commonly taken by heart patients to reduce blood pressure and to treat heart failure.Earlier studies had cautioned that this class of drugs could possibly increase the risk for the novel coronavirus, SARS-CoV-2, infection and elevate COVID-19 severity. There is conflicting observational evidence about the potential clinical impact of ACE inhibitors and ARBs on patients with COVID-19. Select preclinical investigations have raised concerns about their safety in patients with COVID-19. On the other hand, Preliminary data hypothesise that angiotensin-converting enzyme (ACE) inhibitors and renin-angiotensin- aldosterone system (RAAS) inhibitors could benefit patients with COVID-19 by decreasing acute lung damage and preventing angiotensin-II-mediated pulmonary inflammation. Here in our review, we use established and emerging evidence based on the findings of previous studies and researches to propose that ACE inhibitors may benefit patients with COVID-19 via attenuating and abolishing the effect of androgenic hormones on inducing the expression of Transmembrane protease, serine 2 (TMPRSS2), even though, at the same time, ACE inhibitors cause an increase in the human cell surface receptor protein ACE2 which the novel coronavirus uses to enter and infect cells. A study on hypertensive rats demonstrated that using ACE inhibitors(captopril) abolished and attenuated the effect of dihydrotestosterone (DHT). In this study RAS inhibition exhibited beneficial effects on androgen-induced obesity and abolished the androgen-mediated increase in blood pressure (BP) observed in this model of PCOS. (83 ± 1 vs 115 ± 3 mmHg, p<0.0001). A another study found that the angiotensin converting enzyme inhibitor captopril abolished testosterone effect and attenuates testosterone-induced benign prostatic hyperplasia in rats; a mechanistic approach. Captopril is a potent inhibitor of the angiotensin converting enzyme. These effects of testosterone were almost prevented by captopril (100 mg/kg). In conclusion, generally treatment with ACE inhibitors is associated with reduced androgen levels. Therefore,we think that Transmembrane protease, serine 2 (TMPRSS2) is an indirect target of ACE inhibitors and 13 cis retinoic acid As aresult, we hypothesize that any drug which downregulates TMPRSS2 expression through targeting AR, AR co-regulatory factors, or AR downstream transcription factors might be potentially effective against COVID-19 and is worth investigating under a clinical trial.. Keywords: COVID -19, Transmembrane protease, serine 2 (TMPRSS2), ACE inhibitors, ACE2.

Efficacy and Safety of a Highly Selective Semipermeable Membrane (AN-69 Oxiris) vs (Standard AN-69)...

Covid19AKI

Abstract Title: Randomized,open-label, controlled trial to evaluate efficacy and safety of a highly selective semipermeable membrane (AN69-Oxiris) in comparison with a selective semipermeable membrane ( standard AN69) in COVID-19 associated acute kidney injury: oXAKI-COV study Rationale: Acute kidney injury (AKI) in critically ill mechanically ventilated patients with COVID-19 disease, is present in up to 30% of this group and more than 50% of them will need renal replacement therapy in the form of continuous renal replacement therapy (CRRT). Acute kidney injury in this context seems to be a marker of multiorgan dysfunction and it produces increased mortality in this population. There is a vast amount of mechanisms that lead to AKI in critically ill patients with COVID-19; however, the cytokine storm could be the strongest mechanism implicated in AKI development in individuals with continuous renal replacement therapy requirements. Therefore, blocking or reducing the cytokine storm is thought to be a therapeutic target. Highly selective semipermeable membranes (AN69-Oxiris) have been shown able to adsorb endotoxins and to eliminate inflammatory cytokines, thus representing a valuable therapeutic option in this infection. Objective: To demonstrate clinical efficacy of AN69-Oxiris membrane to reach a stable MAP, with less vasopressor dosing (at least 0.1 micrograms/kg/min) after 72h of treatment, compared to a conventional membrane (standard AN69) in critically ill patients with AKI, COVID-19 infection and requirement of continuous renal replacement therapy. Study design: Randomized,open-label, controlled trial in critically ill patients with suspected or confirmed COVID-19 disease, AKI, and criteria for continuous renal replacement therapy initiation admitted in any of the two participating institutions. Patients meeting inclusion criteria will be randomized to receive CRRT with AN69-Oxiris membrane or standard AN69 membrane during a 72h period.

Hidroxicloroquina With Azitromicina Versus Hidroxicloroquina and Placebo Int Patients With Mild...

Covid19

Chloroquine and hydroxychloroquine are two antimalarial drugs that are also used in autoimmune diseases. Chloroquine analogs have been shown to inhibit endosome acidification and exhibit nonspecific antiviral activity at high micromolar concentration in vitro against a wide range of emerging viruses (HIV, dengue, hepatitis C, chikungunya, influenza, Ebola, SARS, and MERS ). virus) and more recently COVID-19. On the other hand, azithromycin is a macrolide antibiotic indicated for infections caused by sensitive pathogens, but which in combination with Hydroxychloroquine has shown a synergistic effect against the SARS-CoV-2 virus. International studies show the lack of beneficial effect in hospitalized or mechanically ventilated patients. Referring that because these medications reduce the in case of having a beneficial effect it would be in the early onset, to avoid inflammation (cytokine storm), and thus prevent hospitalizations. The present study focuses on characterizing the possible synergy of the fixed combination of hydroxychloroquine associated with azithromycin in the treatment of Covid-19 from mild to moderate manifestations. Three treatment schemes are proposed with a 10-day follow-up, a) the fixed combination of Hydroxychloroquine / Azithromycin (combination of interest), b) Hydroxychloroquine (active comparison group) and c) non-active control group, using placebo. A group of patients between 18 and 75 years old is considered, who may or may not present other comorbidities. Follow-up will be carried out through quantification of viral load, evaluation of the systemic inflammatory state, changes in clinical manifestations and possible effect on the reduction of hospitalizations. Therefore, it is proposed to carry out the following project. objective To determine the efficacy and safety of Hydroxychloroquine / Azithromycin fixed combination compared to Hydroxychloroquine or placebo in outpatients with Research design: Phase II, multicenter, prospective, randomized, parallel, longitudinal, double-blind study. Medications to use Group 1. Fixed combination of Hydroxychloroquine with Azithromycin 200 mg / 250 mg one tablet every 12 hours for five days and continue with Hydroxychloroquine 200 mg one tablet every 12 hours for 5 more days. Group 2. Hydroxychloroquine 200 mg, one tablet every 12 hours for ten days. Group 3. Placebo one tablet every 12 hours for ten days.
