Filter by:The Vaccine Product, PTX-COVID19-B mRNA Humoral Vaccine, is intended for prevention of COVID-19 in a general population. This study is designed to evaluate the safety, tolerability, and immunogenicity of PTX-COVID19-B vaccine in healthy seronegative adults aged 18 to 64.
The purpose of this study is to assess the safety and reactogenicity of Ad26.COV2.S administered intramuscularly (IM) as a 1-dose schedule at the standard dose level in adult participants during the second and/or third trimester of pregnancy and (potentially) post-partum; to assess the humoral immune response in peripheral blood of adult participants to Ad26.COV2.S administered IM as a 1-dose schedule during the second and/or third trimester of pregnancy, 28 days after vaccination.
The aim of the study is to evaluate two differents regimens of corticosteroids (prednisolone versus dexamethasone) on D28 mortality in patients with CoViD 19 pneumonia requiring oxygen supplementation
Coronavirus disease pandemic has been started in late 2019. Survivors of COVID-19 are significantly more likely to develop clinical sequelae three months after discharge from the hospital than those without COVID-19 infection. This is true not only for general and respiratory symptoms but also for cardiovascular and psychosocial symptoms. This suggests that these symptoms may indeed be the sequelae of recovery for COVID-19 survivors. So, we aimed to detect the prevalence and to evaluate the type of symptoms that could persist after the recovery from COVID19 infection in Sohag governorate, Egypt.
Multicenter retrospective cohort study from June to August 2020 on hospitalized COVID-19 patients admitted to Al-Hakeem and Al-Amal hospital in Al-Najaf Governorate, Iraq, in order to evaluating the effectiveness of plasma therapy in hospitalized patients with COVID-19 and analyzing factors that affect therapeutic outcome, either related to patients or related to donors.
Patients with Covid-19 (Coronavirus disease 19) may experience multiple neurological symptoms . 18F-FDG PET-CT ( Positons EmissionTomography coupled with a Computer Tomography with flurodesoxyglucose labelled with fluor 18), which reflects neuronal glycolytic metabolism, shows early variations in neuronal function. Moreover the tropism of Covid-19 is essentially pulmonary and the hypothesis of this study is with 18F-FDG PET-CT it's possible to study the relationship between cerebral metabolism and the metabolism of pulmonary lesions following Covid-19 infection.
This study will be conducted in 2 phases. Phase 1 designed to evaluate safety, tolerability and immunogenicity COVID-19 vaccine (NDV-HXP-S) administered at different doses levels (1, 3, and 10 µg) without adjuvant, and at two different dose levels (1 and 3 µg) with the adjuvant CpG 1018 among healthy adults, (age 18-59 years) (210 subjects). Subjects will receive 2 doses of assigned investigational product (IP) on D1 and D29 (V1 and V3), and be assessed in clinic for safety and reactogenicity at 7 days after each vaccination (day 1 as day vaccination). An interim analysis of Phase 1 data will be conducted as the basis for decisions about advancement to Phase 2 of the study and about treatment group down selection. Phase 2 (250 subjects) will include approximately one-third subjects with age 60-75 years.
With the increasing number of COVID-19 infected patients, several studies reported that the liver is the most frequently affected organ after lung damage. The percentage of infected patients who had abnormal levels of transaminases (alanine aminotransferase (ALT) and aspartate aminotransferase (AST)) was about 14.8-53.1%. The elevation in serum bilirubin was mostly mild. Aims of work: - To study liver function tests abnormalities in Egyptian patients who infected with COVID19 - To evaluate if liver function test abnormalities are related to the severity of the Covid19.
An observational study to evaluate the accuracy of a digital cough monitoring tool to reflect the incidence of COVID-19 and other respiratory infections at the community level in the city of Pamplona, Spain.
The primary objectives of the study are: To assess the safety profile of the study vaccines in each study intervention group. To assess the neutralizing antibody profile after primary series vaccination in SARS-CoV-2-naïve adults. To demonstrate that a booster dose of monovalent or bivalent SARS-CoV-2 vaccine given to adults previously vaccinated with an authorized/approved COVID-19 vaccine induces an immune response that is non-inferior to the response induced by a twodose priming series with the monovalent vaccine, and superior to that observed immediately before booster. The secondary objectives of the study are: To assess the neutralizing and binding antibody profiles after primary series vaccination at pre-defined time points during the study. To assess the neutralizing and binding antibody responses of booster vaccination. To describe the occurrences of laboratory-confirmed symptomatic COVID19 after primary series and booster vaccination. To describe the occurrences of serologically-confirmed SARS-CoV-2 infection after primary series vaccination.
