Cytokine storm is the cause of many deaths in COVID -19. The antiviral in-vitro effects of ethanol with solving the fat layer and destroying the glycoprotein of coronavirus have already been established. Proven antiviral effects of ethyl alcohol on extracellular surfaces have been demonstrated by researchers. Immunological studies have shown that acute administration of ethanol can have immunomodulatory effects on innate immunity system mediated by TNFamRNA protein and mitogen-activated protein kinas and reduce cytokine storm by reducing inflammatory factors such as -TLR, TLR, TL-9, interleukin-6 and TL9. It also helps with the chemotaxis of bronchoalveolar macrophages. Other demonstrated effects of ethanol are including: inhibition of virus replication by inhibition of RNA-dependent polymerase, the bronchial dilation by relaxing their involuntary smooth muscles, sedating and relaxation of the participant, muscular analgesic effects. Ethanol administration has previously been reported for the treatment of methanol poisoning, fat embolism, prevention of preterm labor, pre-eclampsia, and pulmonary edema. The histological safety of inhalation ethanol therapy in the lungs and respiratory tracts of rabbits has been shown by Anna Castro-Balado et al. Ethanol is approved by the Food and Drug Administration. Given these effects of ethanol on virus wall destruction, inhibition of proliferation, and inhibition of immune hyperactivity, the question now is, "Can ethanol inhalation therapy be effective in controlling COVID-19?" There is no a prior knowledge of the inhalation ethanol therapy in COVID-19. This idea was first suggested and published one month after COVID-19 pandemic in Iran (February 2020). To find the answer, a clinical trial was conducted to evaluate the effectiveness of ethanol therapy on clinical state and prognosis of participants. The study was approved by the Medical University of Isfahan, research and ethics committees and is registered at https://irct.ir/trial/58201.
COVID-19 has emerged as global pandemic during the past few months, with an unprecedented impact on public health, and society more generally. Virus epidemiology is poorly understood, as are factors influencing the diverse clinical picture. To date most cases have been seen in high income countries and consequently COVID-19 diagnostics and research have mainly been set-up in these settings. Outstanding questions include an understanding of how the virus spreads and how it causes pathology. A particular gap in current knowledge is the effect of HIV and tuberculosis (TB) on the outcomes of COVID-19 disease as these two conditions impair the host immune response to other infectious disease. Understanding how these three pandemics interact is crucial. We have developed a proposal that will answer critical questions concerning COVID-19 disease epidemiology in the context of low resource countries with high burden of poverty, and in the presence of high rates of TB and HIV, namely, Namibia and Botswana. Given that there are currently few cases of COVID-19 diagnosed in both countries, the project will document how the virus spreads within susceptible populations. The development of this proposal is highly collaborative and interdisciplinary, with investigators from Namibia and Botswana working closely with colleagues in Europe. We will also work with an NGO in Namibia, Health Poverty Action, to support rapid implementation. The project includes two studies that will be conducted sequentially. The first study will follow the WHO protocol for household transmission investigations in the context of COVID-19. It will explore transmission frequency and describe the clinical spectrum of disease. Samples collected will also serve as basis for COVID-19 molecular epidemiology and host immunological response. The second study will evaluate the presentation, diagnosis and clinical characteristics of individuals presenting to sentinel health facilities in both countries. The project will have a strong laboratory strengthening component which will enhance COVID-19 laboratory and research capacity. This will include the development of skills and knowledge for diagnostic testing and COVID-19 sequencing and will build scientific and research capacity. The findings from this project will provide robust data to assist in guiding national responses to COVID-19 in both countries as well as assisting with our understanding of the pathogenesis of the virus in the context of TB and HIV, in turn providing vital information on how to deliver clinical care and how to design therapeutics and vaccines.
This study will investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of single ascending doses of APR002 in healthy subjects.
While both heterologous (mixing) and homologous (matching) vaccine regimens are now considered standard of care, post-vaccination complications and long-term effects of the different vaccination regimens have not been thoroughly studied. There is a pressing need to investigate the longitudinal effects of the mixing and matching vaccine-booster approaches. This study proposes to utilize the existing digital infrastructure of the COVID-19 Citizen Science (CCS) study on the Eureka Research Platform to perform a systematic and prospective randomized trial comparing mixing versus matching approaches. Eligible CCS participants will have the opportunity to be randomly assigned to a recommendation of receiving either the Pfizer or Moderna booster vaccine. Long-term effects will be monitored through the participants' completion of their regular weekly CCS follow-up surveys on symptoms and infection. This randomized trial aims to mitigate the effect of confounding variables and provide more conclusive evidence on each regiment to guide booster recommendations.
Background: Respiratory viruses, like the flu or COVID-19, cause significant illness and death worldwide. Researchers want to collect samples from people with respiratory virus infections. The samples in this natural history study will be used in future research. Objective: To obtain samples from people with respiratory viruses to learn more about respiratory virus infections and the immune responses against them. Eligibility: People aged 3 and older who have or are suspected to have a respiratory virus infection. Design: Participants will be screened with a medical record review. Participants will give blood samples. Data from their medical records will be collected. Participants will give nose samples. A soft plastic strip will be put into each nostril for a minute. They may also give nose, mouth (back of the throat), or saliva samples using swabs. Participants may receive kits by mail to collect nose and blood samples at home. They will use soft plastic strips to collect nose samples. To collect blood, they will prick their finger and dab a few drops of blood on four plastic tips. If a participant is in the hospital, air samples may be collected in their room. Participation will last for up to 2 years. After 2 years, participants may be asked for their consent again to give new samples and new medical data.
This clinical trial is a single-blind, randomised study to determine the reactogenicity and immunogenicity of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) vaccine (Pfizer-BioNTech) as booster dose in adults, who have previously received either Sinopharm (BBIBP-CorV®), AstraZeneca (ChAdOx1-S, or Vaxzevria®) or Sputnik V (Gam-COVID-Vac®) as their primary doses 6 to 9 months earlier. Both standard and fractional doses will be tested. Participants are healthy adults aged 18 years or older, with no upper age limit. Procedures will be implemented to ensure participants of all ages (aged 18 and above) are included and that there is an even age distribution (<50 and ≥50 years) in each group. There will be a total of 6 groups (Sinopharm-standard dose Pfizer, Sinopharm-fractional dose Pfizer, AstraZeneca-standard dose Pfizer, AstraZeneca-fractional dose Pfizer, Sputnik - standard dose Pfizer, Sputnik - fractional dose Pfizer), with 200 participants per group for Sinopharm and 100 for AstraZeneca and Sputnik.
Although several studies are conducted in the general population researching the clinical and laboratory parameters predicting the progression to severe disease in COVID-19, the data are very few in obstetric patients. Therefore,the investigators aimed to evaluate the characteristics, prognosis, laboratory parameters, and mortality of obstetric patients followed up in the intensive care unit (ICU) due to severe COVID-19 disease and to determine the factors affecting mortality.
Corona Virus - 19 Disease (COVID-19), caused by Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2), first appeared in Wuhan city of Hubei province of China and spread rapidly, causing a pandemic. In the period from the first emergence of the disease to the present, 336,790,193 people have been infected and 5,560,718 people have died. Considering the severity of the disease, some quarantine measures should be applied, as in many infectious diseases, among the first measures taken worldwide to prevent the spread of the virus.It has been suggested in a limited number of studies conducted in the last two years that climatic conditions may be among the main factors affecting the spread of SARS-CoV-2. However, there is no consensus on the effects of factors such as temperature, humidity, and wind on the spread of the disease, and there are conflicting results. The aim of this study is to determine the relationship between the rate of spread of COVID-19, the rate of intensive care hospitalization and fatality, and weather conditions.
The purpose of this post marketing observational study is to learn about the safety and effects of the commercial medicine (called PAXLOVID) for the treatment of COVID-19. This study is intended to be registered with the participants who: - Have taken PAXLOVID PACK and have no history of using this medicine. - Are 12 years and older All participants will receive PAXLOVID, a standard treatment for COVID-19. Participants will take PAXLOVID 2 times a day by mouth or as prescribed. We will examine the experiences of people taking PAXLOVID. This will help us determine if PAXLOVID is safe and effective. Participants will be followed up for 28 days after taking PAXLOVID. During this time, participants will be closely watched for the safety and effects of PAXLOVID.
