Filter by:Since the beginning of the SARS-CoV-2 pandemic, 1031 (8.7%) of the 11875 kidney transplant recipients being followed up at Hospital do Rim have been infected. The overall lethality rate was 24%, reaching 53% among those over 70 years old. Among the survivors, there is also a high incidence of renal dysfunction with loss of the renal graft and definitive return to dialysis. Patients receiving pharmacological immunosuppression, including transplant recipients, have not been included in the studies carried out to date. In addition, kidney transplant recipients may have reduced vaccine responses compared to the general population. The severity, the high incidence of renal dysfunction and loss of renal graft, and the high lethality associated with COVD-19 justify the investigation of the epidemiological impact and immunogenicity of the vaccine against SARS-CoV-2 infection.
This is randomized trial where households will be randomized to identify the optimal SARS-CoV-2 (COVID-19) testing modality in a population-representative sample of households in Baltimore City, Maryland. 1,386 households in Baltimore City will be randomized 1:1:1 to one of three testing modalities: 1) fixed-site standard of care testing; 2) community-based mobile van testing; or 3) self-collected home, based testing.
The purpose of this study: to assess the safety, tolerability and immunogenicity of the drug "Gam-COVID-Vac", a solution for intramuscular injection, at various times after vaccination in volunteers over 60 years of age
The COVID-19 (coronavirus) pandemic has had a huge impact on healthcare resources and staff in the UK. Understanding the key risk factors associated with infection amongst healthcare workers is essential for future pandemic response plans. Currently there are scarce data relating to the infection rates and associated factors amongst healthcare workers in the United Kingdom (UK). Studies of infection rates in healthcare workers have largely relied on the real-time reverse transcriptase-polymerase chain reaction (RT-PCR) test to date and it appears that Healthcare workers are twice as likely to succumb to Coronavirus infection, when compared to the general population and those from Black and minority ethnic (BAME) backgrounds appear to be particularly at risk. Currently there is no evidence that the presence of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) antibodies provides seasonal or long term immunity to future infection. Therefore, this study aims to understand the current level of SARS-CoV-2 antibody positivity and try to determine the likely risk to healthcare workers in the UK to COVID-19 infection. This study hopes to find out whether certain individual characteristics will have an impact on likelihood of infection susceptibility and antibody response and determine the impact of the presence of antibodies on the likelihood of future clinical infection over a 12 month period. The study involves an initial online survey and linkage to the recent antibody test, then a further online survey in 6 and 12 months' time. The data obtained will be linked to data that the Human Resources Department (HR) holds. Participants also have the option to partake in another antibody test at 6 and 12 months' time and linked to the data collected.
To evaluate pulmonary changes and the results of a cardiopulmonary rehabilitation protocol (CPRP) in patients after SARS-VOC-2 infection. Clinical trial type study to be conducted between 2020 and 2024 involving clinical-functional cardiopulmonary imaging and blood transcriptome profile: before CPRP (T1), 2 months after CPRP (T2) and 1 year later (T3). Expected results: a) clinical, image and transcriptome changes; b) clinical-functional improvement after CPRP.
In this trial patients will be treated with either a combination of therapies to treat COVID-19 or a placebo. Treatment will last 10 days, and patients will be followed for 6 months.
A prospective and retrospective cohort study. The objective will to determine the frequency of COVID-19 in pregnant and postpartum women hospitalized with flu syndrome, to evaluate clinical and laboratory predictors of COVID-19 progression and to determine the factors associated with adverse maternal and perinatal outcomes in healthcare centers in two states of Northeast Brazil.The study will be conducted including pregnant and postpartum women with clinical or laboratorial diagnosis of COVID-19, admitted in six healthcare centers in the Northeast of Brazil. All pregnant and postpartum women with clinical and/or diagnosis of COVID-19, attended in prenatal care, in emergency (maternity triage), high-risk pregnancy ward, obstetric intensive care unit and rooming-in ward will be included. The data will be collected in specific forms. The exams will be carried out by trained professionals within each institution.
Patients suffering from pneumonia due to SARS-CoV-2 infection, after admission to the Intensive Care Unit (ICU), are susceptible to development of various functional sequelae, increased risk of chronic diseases, increased mortality rates and existence of relevant impacts on their quality of life in the months and years that follow the ICU admission. The present study aims to assess the determinants of health-related quality of life and patient-centered long-term outcomes among patients recovered from SARS-COV-2 pneumonia, after discharge from the ICU, its determinants and predictors, in Portugal. It is a multicenter prospective cohort study of adult patients admitted at the ICU due to proven or suspected SARS-CoV-2 infection, included 90 days after discharge from the ICU. The primary outcome is one-year health-related quality of life assessed by the EQ-5D-3L. The secondary outcomes are all-cause mortality, rehospitalizations, return to work or study, the degree of dependence and functional capacity, symptoms of anxiety, depression and post-traumatic stress, level of physical activity and cognitive, renal and respiratory functions after ICU discharge. Investigators will collect data by means of structured telephone interviews, at a 12 months follow up period.
This study is a Phase 1 / 2 trial to determine the safety and efficacy of CYNK-001, an immunotherapy containing Natural Killer (NK) cells derived from human placental CD34+ cells and culture-expanded, in patients with moderate COVID-19 disease.
This is a prospective adaptive cohort study of St. Jude employees to determine the rate of SARS-CoV-2 infections that are asymptomatic and to evaluate immunological responses to SARS-CoV-2 infection. Primary Objectives - To estimate the proportion of asymptomatic infection with SARS-CoV-2 infection in a population of SARS-CoV-2-naïve adult St. Jude employees - To comprehensively map CD4 and CD8 T cell epitopes and response magnitudes to SARS-CoV-2 infection in a population of SARS-CoV-2-naïve adult St. Jude employees who acquire SARS-CoV-2 infection - To measure changes in the CD4 and CD8 response magnitude and function to SARS-CoV-2 infection and/or vaccination in a population of St. Jude employees for up to 48 months after infection and/or vaccination. Secondary Objectives - To establish seroprevalence of SARS-CoV-2-specific antibodies at baseline, and identify the rate of seroconversion to SARS-CoV-2 in a population of presumably naïve adult St. Jude employees - To identify features of T cell responses at baseline and during SARS-CoV-2 infection that are associated with protection against symptomatic or severe COVID-19 disease in a population of adult St. Jude employees - To identify risk factors for long-term protection against COVID-19 in a population of adult St. Jude employees - To evaluate changes in antibody responses to SARS-CoV-2 in a population of St. Jude employees for up to 48 months after SARS-CoV-2 infection and/or vaccination. - To evaluate the saliva antibody and cytokine response to SARS-CoV-2 infection and/or vaccination and identify characteristics that predict protection from subsequent SARS-CoV-2 infection among a population of St. Jude employees followed for up to 48 months after SARS-CoV-2 infection and/or vaccination. - To measure changes in saliva antibody responses to SARS-CoV-2 for up to 48 months after SARS-CoV-2 infection and/or vaccination. Exploratory Objectives - To establish additional immunological features including host immune or receptor polymorphisms associated with response to SARS-CoV-2 infection - To explore SARS-CoV-2 diversity and specific features in a circumscribed population - To describe the presence, characteristics, and proportion of short-term re-infection - To determine if an association between SARS-CoV-2 viral load in nasal swab specimens and COVID-19 symptoms can be identified in a population of adult St. Jude employees who acquire SARS-CoV-2 - To explore the laboratory and clinical response to SARS-CoV-2 vaccine in a population of adult St. Jude employees with and without a history of SARS-CoV-2 infection
