Filter by:The Malaysian COVID-19 Anosmia Study is a nationwide multicentre observational study to investigate the prevalence and characteristics of olfactory and gustatory/taste disturbances in COVID-19 infection in Malaysia, and to evaluate the predictive value of screening for these symptoms in COVID-19 infection. This study consists of two phases: the first phase is a cross-sectional study and the second phase is a case-control study. The case-control study is described here (the cross-sectional study is described in a separate ClinicalTrials.gov record).
It has been suggested that ibuprofen might be associated with more severe cases of coronavirus infections, based on the observation that severe COVID cases had been exposed to ibuprofen, resulting in a warning by the French authorities. This was attributed to: 1. a suggestion that ibuprofen might upregulate ACE-2 thereby increasing the entrance of COVID-19 into the cells, 2. an analogy with bacterial soft-tissue infections where more severe infections on NSAIDs are attributed to an immune-depressive action of NSAIDs, or to belated treatment because of initial symptom suppression, 3. fever is a natural response to viral infection, and reduces virus activity: antipyretic activity might reduce natural defenses against viruses. However fever reduction in critically ill patients had no effect on survival. However, these assertions are unclear: upregulation of ACEII would increase the risk of infection, not necessarily its severity, and would only apply to the use of NSAIDs before the infection, i.e. chronic exposure. It would be irrelevant to the infection once the patients are infected, i.e., to symptomatic treatment of COVID-19 infection. Anti-inflammatory effect masking the early symptoms of bacterial infections resulting in later antibiotic or other treatment is not applicable: there is no treatment of the virus that might be affected by masking symptoms. Antipyretic effect increasing the risk or the severity of infection would apply equally to all antipyretic agents including paracetamol, which share the same mechanism of action for fever reduction. EMA remains prudent about this assertion In addition, excess reliance on paracetamol while discouraging the use of ibuprofen might increase the risk of hepatic injury from paracetamol overdose. Paracetamol is the prime drug associated with liver injury and transplantation, in voluntary and inadvertent overdose or even at normal doses. This might be increased by COVID-related liver function alterations. It is therefore proposed to conduct a case-control study in a cohort of patients admitted to hospital in France with COVID-19 infection.

Combination of Recombinant Bacterial ACE2 receptors -like enzyme of B38-CAP and Isotretinoin could be promising treatment for COVID-19 infection- and Its inflammatory complications Mahmoud ELkazzaz1 1Department of chemistry and biochemistry, Faculty of Science, Damietta University, Egypt. _____________________________________________________________________________________________ ________________________________________________________________________ B38-CAP is a bacteria-derived ACE2-like enzyme that suppresses hypertension and cardiac dysfunction Angiotensin-converting enzyme 2 (ACE2) is critically involved in cardiovascular physiology and pathology, and is currently clinically evaluated to treat acute lung failure. Here we show that the B38-CAP, a carboxypeptidase derived from Paenibacillus sp. B38, is an ACE2-like enzyme to decrease angiotensin II levels in mice. In protein 3D structure analysis, B38-CAP homolog shares structural similarity to mammalian ACE2 with low sequence identity. A study demonstrated that the bacterial B38-CAP as an ACE2-like carboxypeptidase, indicating that evolution has shaped a bacterial carboxypeptidase to a human ACE2-like enzyme. Bacterial engineering could be utilized to design improved protein drugs for hypertension and heart failure. pretreatment of B38-CAP markedly down regulated a massive increase of plasma Ang II levels at 5 min after Ang II injection In addition to the currently used drugs to inhibit Ang II generation or signaling, such as ACE inhibitors or Angiotensin receptor blockers, direct down-modulation of Ang II levels by rhACE2 protein is one of the promising candidates for new therapeutic strategy in cardiovascular disease and other Ang II-related diseases, e.g. ARDS. On the other hand, although mass production of rhACE2 as a protein drug costs due to requirement of mammalian cell expression systems, B38-CAP is easily prepared with E. coli expression system and is cost effective. Therapeutic efficacy and less toxicity in mouse heart failure models would warrant further investigation of B38-CAP or other microbial carboxypeptidases in disease models. Finally the principal investigator expects that treatment with ACE2-like enzyme of bacteria B38-CAP expected to work efficiently Like human ACE2 and it will save the lung cells from COVID - 19 inhibitory effect and down regulation of ACE2 because COVID-19 binds to human ACE2 and down regulates it and this receptors is very important for lung cells survival and function So ,the principal investigator also expects that B38-CAP ACE2 like enzyme may be not recognized by COVID -19 spike protein because evolutionary it is too far away from human ace2 and human ACE2 is a real receptor of COVID -19 not ACE2 like enzyme but in the same time it will make the same function of human ACE2 In another study by Sinha et al who analyzed a publicly available Connectivity Map (CMAP) dataset of pre/post transcriptomic profiles for drug treatment in cell lines for over 20,000 small molecules, isotretinoin was the strongest down-regulator of ACE 2 receptors. On the other hand, they found 6 drugs in CMAP that are currently being investigated in clinical trials for treating COVID-19 (chloroquine, thalidomide, methylprednisolone, losartan, lopinavir and ritonavir, from clinicaltrials.gov), none of which was found to significantly alter ACE2 expression (P>0.1) Moreover, another study demonstrated that isotretinoin is a Potential papain like protease (PLpro) inhibitors which is a protein encoded by SARS-CoV-2 genes and considered one of the proteins that should be targeted in COVID-19 treatment by performing target-based virtual ligand screening . So, the principal investigator expects strong inhibition of COVID - 19 infection And rescuing the lung cells from its serious attack by treating with ACE2 like enzyme and Isotretinoin Keywords: COVID 2019 , Isotretinoin,B38-CAP , Bacterial ACE2 receptors -like enzyme , rhACE226.
A weekly questionnaire is sent to patients and parents of patients who are vulnerable for infections. Possible symptoms of COVID19 are asked for and use of healthcare services and testing for COVID19. Weekly reports are being send to the national institutions to update advice given to this group.
Agent Name and Study Duration ArtemiC is a medical spray comprised of Artemisinin (6 mg/ml), Curcumin (20 mg/ml), Frankincense (=Boswellia) (15 mg/ml) and vitamin C (60 mg/ml) in micellar formulation for spray administration. Patients will receive up to 6 mg Artemisinin, 20 mg Curcumin, 15 mg Frankincense and 60 mg vitamin C given daily as an add-on therapy (in addition to standard care) in two divided doses, on Days 1 and 2. Patients will be randomized in a manner of 2:1 for study drug (ArteminC) and Standard of Care to Placebo and Standard of Care. Patient follow-up will last 2 weeks. During this time, patients will be monitored for adverse events. Additional time will be required for follow up (until hospital discharge) in order to check side effects and study drug efficacy. Placebo, composed of the same solvent but without active ingredients, will be given in the placebo group as add-on therapy, 2 times a day, on Days 1 and 2. Overall rationale A preparation of ArtemiC, comprising Artemisinin, Curcumin, Boswellia, and Vitamin C, is proposed as a treatment for the disease associated with the novel corona virus SARS-CoV-2. It is readily available in light of its status as a food supplement. This initiative is presented under the urgent circumstances of the fulminant pandemic caused by this lethal disease, which is known as COVID-19 and has spread across the globe causing death and disrupting the normal function of modern society. The grounds for the proposal are rooted in existing knowledge on the components and pharmacological features of this formulation and their relevance to the current understanding of the disease process being addressed. Leading among these considerations are well established immuno-modulatory activities of the active ingredients as established in vitro and in vivo and published over the years. These activities as apparent, for example, in diminishing activity of TNF alpha and IL-6 levels are acknowledged to be relevant to the pathophysiology processes involved in the progressive form of COVID-19. The active agents have in addition prominent anti-oxidant, anti-inflammatory as well as anti-aggregant and anti-microbial activities. Based on these activities and observations in animal models, together with clinical experience of the separate ingredients and in various combinations in other contexts it is proposed to evaluate their effect in the context of COVID-19. Study Purpose This study is designed to evaluate the safety and efficacy of ArtemiC on patients diagnosed with COVID-19. Methodology 50 adult patients who suffer from COVID-19 infection studied in parallel groups treated with active agent or placebo as add on to standard care. Safety will be assessed through collection and analysis of adverse events, blood and urine laboratory assessments and vital signs.
Main goal: To generate information on the efficacy and safety of Dialyzable Leukocyte Extract (DLE) as an aid in the treatment of patients with acute respiratory infection (suspected or confirmed cases of COVID-19). Primary goal: To generate information on the efficacy of DLE as an aid in symptomatic treatment, by reducing the signs and symptoms of acute respiratory infection (suspected/confirmed cases of COVID-19). Secondary goals: 1. To evaluate clinical deterioration and respiratory alarm data. 2. To evaluate the duration of the clinical picture. 3. To explore cytokine changes associated with the therapeutic effect induced by DLE. 4. To obtain data on the safety of DLE as an aid in the symptomatic treatment of acute respiratory infection (suspected/confirmed cases of COVID-19). 5. To generate information to validate the contingency scale to assess the severity of acute respiratory disease (suspected/confirmed cases of COVID-19). Justification The systemic inflammatory response has been recognized as being responsible for COVID-19 complications. Immunomodulation strategies to control it are currently being considered, including the use of systemic steroids to down-regulate the systemic inflammatory response, the use of human immunoglobulin and even chloroquine given its anti-inflammatory and antiviral qualities; however, none of these treatments has been sufficiently studied or has shown any significant change in the clinical course of infected patients. Due to the importance of the COVID-19 pandemic and in the absence of specific treatment, it is important to implement new treatments that allow modulating the immune response, and one strategy may be the addition of DLE to symptomatic and supportive treatment. Hypotheses by goals. 1. The addition of DLE to the symptomatic treatment could decrease the severity of the clinical outcome (signs and symptoms) in individuals with an acute respiratory infection (cases suspected/confirmed by COVID-19). 2. The addition of DLE to the symptomatic treatment could decrease the clinical deterioration due to the acute respiratory infectious process (suspected/confirmed cases of COVID-19). 3. The addition of DLE to the symptomatic treatment could decrease the duration of the clinical outcome (suspected/confirmed cases of COVID-19).
The SARS-CoV-2 epidemic was declared as a global pandemic by the WHO on March 12, 2020. France is affected with approximately 120,000 biologically confirmed cases, as of April 30, 2020, a figure probably very underestimated. Its distribution in different populations, in particular immunocompromised, has not yet been measured. The in vitro efficacy of lopinavir coupled with ritonavir, an HIV protease inhibitor, on SARS-CoV, responsible for SARS has been discussed and this therapeutic combination is currently being evaluated in patients infected with COVID-19. The possible protective role of treatment with Lopinavir / ritonavir or another HIV protease inhibitor has not been studied. In addition, patients receiving HIV pre-exposure prophylaxis (PrEP) share certain epidemiological and behavioral characteristics with HIV-infected patients. The objective was to carry out an epidemiological study aimed at determining the attack rate of COVID-19 infection in patients infected with HIV and or on PrEP and to analyze this attack rate according to the characteristics of these 2 populations and in particular the existence or not of an antiretroviral treatment comprising Lopinavir / Ritonavir or another inhibitor of the HIV protease. Cross-referencing of Virology Laboratory data (positive or negative screening) and clinical-biological data can be easily carried out using a unique identification number in the 2 software programs and will allow an almost exhaustive epidemiological analysis in 2 well identified populations.
