Filter by:A new coronavirus (COVID-19) highlighted at the end of 2019 in China is spreading across all continents. Most often at the origin of a mild infectious syndrome, associating benign symptoms (such as fever, cough, and headache) to different degrees, COVID-19 can cause serious pulmonary pathologies and sometimes death. Data on the consequences during pregnancy are limited. The first Chinese data published seem to show that the symptoms in pregnant women are the same as those of the general population. There are no cases of intrauterine maternal-fetal transmission, but cases of newborns infected early suggest that there could be vertical intrauterine, perpartum or neonatal transmission. Prematurity and cases of respiratory distress in newborns of infected mothers have been described. Subsequently, an in-depth analysis of cases in pregnant women and pregnancy issues are necessary in order to improve knowledge on the subject.
Clinical manifestations of Covid-19 are poorly characterised in HIV co-infection, which may predispose to more severe disease. Reducing hospitalisation and severe illness in this population has important individual and public health benefits. The investigators propose a pragmatic multi-centre, randomized controlled trial in South Africa to evaluate the efficacy and safety of chloroquine or hydroxychloroquine to prevent progression of disease and hospitalisation amongst HIV-positive people with Covid-19 not requiring hospitalisation at initial assessment.
To better understand the immune response to SARS-CoV-2 infection, we devised a precision immunology approach to systematically study the immune function of different patient cohorts
This study will enroll 40 symptomatic outpatients tested positive for Coronavirus 2019 (COVID-19). Patients to be randomized 1:1 to Telmisartan (40 mg) vs placebo to be administered orally once daily x 21 days. Daily, the study patients will be asked to keep a record of the severity of their fever, dyspnea and fatigue and take their blood pressure (BP) and temperature. Study visits to occur on day 1 (entry), day 4, day 10 and day 21. Oro-pharyngeal swabs, and approximately 25 cc of blood will be collected at each study visit for safety labs and for the evaluation of the renin-angiotensin system (RAS) system and for various blood biomarkers of inflammation, coagulation and fibrosis.
The investigators hypothesize that those with respiratory failure due to COVID-19 will have different burdens of mental and physical disability than those with respiratory failure who do not have COVID-19. Detecting these potential differences will lay an important foundation for treating long term sequelae of respiratory failure in these two cohorts.
This treatment protocol is designed to provide convalescent plasma as a therapeutic option for patients diagnosed with and hospitalized for COVID-19 with symptoms ranging from mild to life-threatening.
Research Background and Rationale In December 2019, a new infectious respiratory disease emerged in Wuhan, Hubei province, China. An initial cluster of infections was linked to Huanan seafood market, potentially due to animal contact. Subsequently, human-to-human transmission occurred and the disease, now termed coronavirus disease 19 (COVID-19) rapidly spread within China and all over the world. A novel coronavirus, SARS-coronavirus 2 (SARS-CoV-2), which is closely related to SARS-CoV, was detected in patients and is believed to be the etiologic agent of the new lung disease. The causative agent of the current COVID-19 pandemic, SARS-CoV-2, is a single stranded positive sense RNA virus that is closely related to severe acute respiratory syndrome coronavirus (SARS-CoV).
Background: The Coronavirus disease 2019 (COVID-19) pandemic is a major public health issue. Researchers want to collect plasma from people who have recovered from COVID-19, and use this plasma to treat people who are sick with the disease. The plasma will have antibodies against the virus that causes COVID-19. Persons who have received a COVID-19 vaccine may also donate plasma that contains antibodies against the virus if they meet criteria according to the FDA. Objective: To collect plasma from people who have recovered from COVID-19 or have been vaccinated against the coronavirus that causes COVID-19, so that the plasma can be used to treat people with the disease. Eligibility: Adults ages 18 and older who have been diagnosed with, and have recovered from, COVID-19. Design: Participants will be screened with a physical exam, medical history, and blood sample. Their pulse, blood pressure, and temperature will be taken. Their height and weight will be recorded. Participants will donate plasma. It will be collected through whole blood donation or through apheresis. For whole blood donation, a needle will be placed in the participant s arm vein. Blood will be withdrawn. For apheresis, a needle will be placed in the participant s arm vein. Blood will be withdrawn. A machine will separate the plasma from the red cells. The plasma will be removed, and the rest of the cells will be returned to the participant either through the same needle or through a needle in their other arm. Participants will have 3 to 20 plasma donations. Participation will last up to 3 years.
This randomized open labeled clinical trial will include one hundred healthy healthcare workers who will be randomly assigned into four groups of twenty-five each to receive either levamisole, Isoprinosine, combined levamisole and isoprinosine or no-intervention for two months to detect the impact of Levamisole and Isoprinosine as immune-prophylaxis on the incidence of COVID-19 infection. Participants will be followed-up for three months clinically and laboratory. Blood samples will be collected prior to randomization and during follow up.
Brief Summary: SARS-CoV-2 virus infection is known to cause Lung Injury that begins as dyspnea and exercise intolerance, but may rapidly progress to Critical COVID-19 with Respiratory Failure and the need for noninvasive or mechanical ventilation. Mortality rates as high as 80% have been reported among those who require mechanical ventilation, despite best available intensive care. Patients with severe COVID-19 by FDA definition who have not developed respiratory failure be treated with nebulized ZYESAMI™ (aviptadil acetate, a synthetic version of Vasoactive Intestinal Polypeptide (VIP)) 100 μg 3x daily plus Standard of Care vs. placebo + Standard of Care using an FDA 501(k) cleared mesh nebulizer. The primary outcome will be progression in severity of COVID-19 (i.e. critical OR severe progressing to critical) over 28 days. Secondary outcomes will include blood oxygenation as measured by pulse oximetry, dyspnea, exercise tolerance, and levels of TNFα IL-6 and other cytokines.
