Active clinical trials for "COVID-19"

This is prospective cohort study aimed to compare antibody response against SARS-CoV-2 in dialysis patients and non-dialysis-dependent volunteers. The research hypothesis is that dynamic of IgG antibodies against SARS-CoV-2 will differ in two groups. To determine whether there is a statistically significant interaction between factors "group" and "time" on the titer of IgG antibodies against SARS-CoV-2, a two-way repeated measures ANOVA will be used.

This prospective observational pilot study investigates circulatory coherence in patients with COVID and non-COVID sepsis by comparison of microcirculation, endothelial glycocalyx, and clinical course

The purpose of this study is to Understand the natural history of Coronavirus 2019 (COVID-19) infection to better define the period of infectiousness and transmissibility and to establish biobanks of COVID-19 blood and mucosal samples.

This study was carried out to determine the fear of Covid-19 and the compliance with protective measures of students who continue their education face-to-face during the covid-19 pandemic process.

The International Registry of Healthcare Workers Exposed to COVID-19 Patients (UNITY Global), is an international registry of approximately 10,000 healthcare workers in low- and middle-income countries experiencing increasing numbers of COVID-19 cases and commensurate increased exposure to the SARS-CoV-2 virus among their healthcare worker populations.

Since December 2019, coronavirus disease 2019 (COVID-19), caused by the severe respiratory syndrome coronavirus 2 (SARS-CoV-2), has affected more than 124 million people worldwide as of 23/3/2021. While studies on the outcomes of inflammatory bowel disease (IBD) (an important gastroenterological disease requiring immunosuppressive therapies for treatment) patients with COVID-19 have been published recently, little is known about the impact of COVID-19 on the clinical outcomes and management of IgG4 related disease patients with pancreatobiliary involvement. Because the number of IgG4 patients with pancreatobiliary involvement cared by individual centers and the prevalence of COVID-19 infection in different geographical regions vary, we propose to conduct a multicenter retrospective study to further evaluate the impact of COVID-19 on the clinical outcomes and management of IgG4 related disease patients with pancreatobiliary involvement.

This retrospective observational cohort study aims to describe the impact of COVID-19 in patients treated with autologous stem cell transplantation (ASCT) for malignant disease in terms of risk factors, morbidity, need for supportive care and mortality. All patients treated with ASCT in Sweden from 1st January 2020 until 31st December 2020 are eligible for this study. Patients who also has tested positive for SARS-CoV-2 from start of conditioning or later will be identified through the national registry of the Public Health Agency of Sweden and a systematic analysis of their medical records will be performed.

The goal of the project: to study the dynamics of the humoral and cellular immunity in patients after pneumonia caused by the SARS-CoV-2 virus at different time intervals, in order to predict the duration of immune protection

The vaccination policy is drawn up in France by the French Minister of Health, who makes public the vaccination schedule after the opinion of the High Authority of Health. Currently according to the 2019 immunization schedule, the dTP vaccine is the only mandatory in the general population with recalls in adults aged 25, 45, 65 and every 10 years. In 2011, the Ministry of Health estimated that only 50.5% of the general population was up to date against dTP. Two vaccines are recommended for person at risk of infection according to the current vaccine schedule: the flu vaccine and the pneumococcal vaccine. In fact, influenza and pneumococcal disease are more frequent and more serious in patients with chronic diseases (diabetes, cardiac insufficiency..) compared to the general population. The vaccination coverage rate of at-risk populations is dramatically below the vaccination coverage targets set by the Ministry of Health. Indeed, there are many barriers to vaccination, medical and para-medical barriers, but also individual barriers. The current COVID-19 pandemic has identified people at risk of severe infection and death risk, particularly those with co-morbidities (diabetes, cardiovascular disease, etc.). Thus, this pandemic may have contributed to change in patients' perceptions regarding both the risk of infection and the potential interest and benefit of vaccination.

The purpose of this study is to test over time immunity to the COVID-19 vaccines. Adults who are receiving COVID-19 vaccines will be invited to participate.
