Filter by:The study is open label randomized interventional phase 3 clinical trial. Patients with confirmed Covid-19 cases who was hospitalized in Two university isolation hospitals (Ain Shams University and Assiut University ) assigned hospitals for isolation.
Olfactory dysfunction is common among patients with Corona-Virus-Infection-Disease (COVID)-19, and up to 30% of patients may report persistent disorders of smell or taste as a long-term sequelae. This randomized-controlled study has addressed to compare the efficacy of neuro-protective and anti-inflammatory agents palmitoylethanolamide (PEA) and Luteolin(Treatment) with control (olfactory training) in a cohort of patients who present persistent smell disorders after resolution from Covid-19 and negative swab for 4 months at least.
The primary objective of this study is quantify the transmission risk posted by SARS-CoV-2 in pre/asymptomatic infected children in order to inform the public health response to the COVID-19 pandemic.
This study is intended to explore the possible protective role of anti-androgens in SARS-CoV-2 infection
This study seeks to evaluate how secondary data retrieved from remote physiological monitoring performed during routine outpatient/at-home care periods can allow for the discovery of novel physiomarkers that predict acute deterioration or hospitalization among people testing positive for Coronavirus Disease 2019 (COVID-19).
The aim of this trial is to determine whether oestrogen treatment mitigates disease progression and severity in confirmed COVID19.
To investigate the incidence of SARS-CoV-2 infections after vaccination, to monitor the development of SARS-CoV-2 antibody levels after vaccination and to compare this in relation to both previous health & disease, previous antibody responses and in relation to future disease occurring after vaccination.
This is a randomized phase IV dose-optimization study evaluating the safety and immunogenicity of two doses of COVID-19 mRNA vaccines being authorized in the European Union since December 2020: Vaccine BNT162b2 (Comirnaty®; Pfizer-BioNTech) in healthy adults up to age 55 year. Immunogenicity will be measured 28 days after first and second dose, and day 180 and day 365 after first vaccination of 20 and 30 mcg of BNT162b2. The primary outcome is the level of binding antibodies for RBD 28 days after the second dose.
Vaccination remains the main promising measure to fight against the COVID-19 pandemic. The presumed efficacy of the vaccines is quite remarkable since it varies between 62 and 95%. There is increasing evidence that sex-specific effects may lead to different outcomes of vaccine safety and efficacy. However, sex-disaggregated data after COVID-19 vaccine are lacking. The first purpose of the study is to determine antibody titers against SARS-CoV-2 spike after COVID-19 vaccination. The secondary purpose is to identify predictor factors of immune response including age, gender and biological factors.
Coronavirus disease 2019 (COVID-19) is an emerging infectious disease that was first reported in December 2019 in Wuhan, China. Infection with this new coronavirus called SARS-CoV-2 can lead to fatal pneumonia associated with high rates of hospitalization in intensive care units (ICU). Hospitalized patients with hematologic malignancies have a higher mortality rate than patients without hematologic malignancies (62% vs. 8%). The severity of Covid-19 may be related to their treatment, in particular anti-CD20 used in B lymphoid hemopathies. In fact, anti-CD20 antibodies induce rapid and prolonged depletion of B cells, but they are necessary for development. humoral immune responses. But currently, no immunogenicity data are known for patients with hemopathy or in those on anti-lymphocyte immunochemotherapy.
