COVID-19 Clinical Trials and Expanded Access

confirmed cases with COVID-19 will receive ivermectin as a therapeutic option as well as standard of care treatment and will be compared to those that will receive only standard of care ttt

Inflammatory diseases favour the onset of venous thromboembolic events in hospitalized patients. Thromboprophylaxis with a fixed dose of heparin/low molecular weight heparin (LMWH) is recommended if concomitant inflammatory disease. In severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) pneumonia an inflammation-dependent thrombotic process occurs and platelet activation may promote thrombosis and amplify inflammation, as indicated by previous experimental evidence , and the similarities with atherothrombosis and thrombotic microangiopathies. Antiplatelet agents represent the cornerstone in the prevention and treatment of atherosclerotic arterial thromboembolism, with limited efficacy in the context of venous thromboembolism. The use of purinergic receptor P2Y12 inhibitors in pneumococcal pneumonia may improve inflammation and respiratory function in humans. There are no validated protocols for thrombosis prevention in Covid-19. There is scientific rationale to consider a P2Y12 inhibitor for the prevention of thrombosis in the pulmonary circulation and attenuation of inflammation. This is supported by numerous demonstrations of the anti-inflammatory activity of P2Y12 inhibitors and the evidence of improvement in respiratory function both in human and experimental pathology. Prasugrel could be considered as an ideal candidate drug for Covid-19 patients because of higher efficacy and limited Interactions with drugs used in the treatment of Sars-CoV2. The hypothesis underlying the present study project is that in Covid-19 platelet activation occurs through an inflammation-dependent mechanism and that early antithrombotic prophylaxis in non-critical patients could reduce the incidence of pulmonary thrombosis and respiratory and multi-organ failure improving clinical outcome in patients with SARS-CoV2 pneumonia. The prevention of thrombogenic platelet activity with a P2Y12 inhibitor could be superior to fixed dose enoxaparin alone. The proposed treatment is feasible in all coronavirus disease 2019 (COVID-19) patients, regardless of the treatment regimen (antivirals, anti-inflammatory drugs, antibiotics), except for specific contraindications.

Patients with COVID-19 associated ARDS and mechanical ventilation have a high mortality. Part of the disease is an activation of the coagulation system which seems to contribute to clotformation in the pulmonary bloodstream. Recently we implemented an algorithm applying higher doses of heparins (LMWH). However, this approach could not inhibit clotformation enough. Bivalirudin could prevent clotformation better and support dissolving existing clots. Therefore, we want to compare 50 patients with the standard treatment with 50 patients under bivalirudin treatment which we normally apply in patients with a HIT-syndrome. Our primary outcome measure is oxygenation reflected as P/F ratio.

COVID-19 antibodies testing among healthcare workers to evaluate the role of Covid 19Ab testing as screening method for detection of covid 19 infections among laboratory health care workers ,assess the relationship between the infection with Covid 19 and different laboratory categories/area and assessemt of efficiency personal protective equipment (PPE) in different laboratory categories/area.

In times of pandemics, social distancing, isolation and quarantine exacerbate depression and anxiety as confined people are detached from their loved ones, deprived of personal liberties, and devoid of purpose owing to altered routine and livelihood (1,2). Those with pre-existing mental health problems or illnesses (MHPIs) might suffer from limiting interpersonal interactions that are central to their self-management, as well as reduced access to helpful but "non-essential" (often cancelled) psychiatric services (3). In response to this situation, this feasibility study of a trial consists of offering a transitional measure of online peer support for people suffering from (a) psychotic disorders or (b) anxiety and mood disorders, and to determine an effect size to this Peer Support Workers-delivered intervention in terms of both personal-civic recovery and clinical recovery (4). Peer Support Workers (PSWs) are persons with first-hand lived experience of MHPIs, and who are further along in their own recovery journey. As recommended by recovery-oriented best practices guidelines (5,6), upon training and certification they can provide supportive services when hired to fill such a paid specialty position directly in, or in conjunction with, current psychiatric services. Indeed, recovery focuses on how individuals can have more active control over their lives (agency). It is characterized by a search for the person's strengths and capacities, satisfying and meaningful social roles, and mobilizing formal and informal support systems. Peer support has thus become one predominant concept in the recovery paradigm and PSWs are specialized in peer support. Yet, not much is known about the efficacy of PSWs from a consumer's perspective of personal-civic recovery. The five principal research questions are whether this online intervention will have an impact in terms of (Q1) personal-civic recovery potential and (Q2) clinical recovery potential, (Q3) how these potentials can be impacted by the COVID-19 pandemic, (Q4) how the lived experience of people in recovery can be mobilized to cope with such a situation, and (Q5) how sex and gender considerations can be taken into account for the pairing of PSWs with service users, beyond considerations based solely on psychiatric diagnoses or specific MHPIs.

The objective of this study is to screen the patients seeking hospitalization in Ain Shams university hospitals and identify a cost effective tool for continuing screening the patients all through the epidemic period

A Phase I/II, double-blinded, placebo-controlled, individually randomized trial to assess safety, immunogenicity and efficacy of the candidate Coronavirus disease (COVID-19) vaccine ChAdOx1 nCoV-19 in adults aged 18-65 years living with and without HIV in South Africa. The vaccine or placebo will be administered via an intramuscular injection into the deltoid muscle of the non-dominant arm.

The aim of this possible study is to identify if SARS-CoV-2 can be found in the tear film and conjunctiva of a patient with COVID-19.

Since the outbreak of coronavirusdisease2019(COVID-19), many researchers in China have carried out/published clinical trials on treatment based on Western medicine, traditional Chinese medicine or a combination of the two. Trials on treatment modalities have mainly used antivirals, interferon, glucocorticoids in addition to traditional Chinese medicine. There are also clinical trials exploring hydroxyquinoline/chloroquine sulphate, immunoglobulins, Vitamin-C, washed microbiota, nebulized interferon, teicoplanin as well as Mesenchymal stem cells. However, most of these trials were small (median sample size 100) and the bulk of potential therapeutic strategies remain in the experimental phase and currently there is no effective specific antiviral with high-level evidence.The aim of this study is assess the efficacy of MSCs as an add-on therapy to standard supportive treatment for patients with moderate/severe COVID-19.

The primary objective of this study is to evaluate the efficacy and security of chloroquine phosphate prophylactic use for reducing the risk of infection by severe acute respiratory syndrome coronavirus-2 in Health Care Workers exposed to COVID-19 patients.
