Active clinical trials for "COVID-19"

Assessment of the seroprevalence and sero-incidence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) among Nursing Home (NH) residents and staff in Belgium.

This is a multisite prospective observational study to evaluate the clinical sequelae of symptomatic and asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in the pediatric population, including coronavirus disease 2019 (COVID-19) and multisystem inflammatory syndrome in children (MIS-C), and characterize the immune response associated with these clinical presentations. Participants aged 21 years and younger with laboratory confirmed history of symptomatic or asymptomatic SARS-CoV-2 infection will visit the study sites for clinical and research evaluations and sample collection at schedules dependent on time since infection. Participants enrolled within 12 weeks after acute infection or positive test will be part of the "recovery group" and will attend study visits at baseline, every 3 months for the first 6 months, and subsequently every 6 months for a total of 3 years. Participants enrolled more than 12 weeks after acute infection or positive test will be in the "convalescent group" and will attend study visits at baseline and subsequently every 6 months for a total of 3 years. Individuals (aged ≤21 years) without a diagnosis of SARS-CoV-2 infection or current symptoms suggestive of COVID-19 will serve as a control group and will attend visits for evaluations and sample collection at baseline and every 12 months for a total of 3 years. This protocol will establish a cohort of pediatric patients recovered from SARS CoV-2 infection and a biorepository for evaluation of the potential roles of host genetics, immune response, and other possible factors influencing long-term outcomes. Parents or guardians of participants in all cohorts will also be enrolled for limited participation to complete questionnaires about how the family is impacted by the participant's health and SARS-CoV-2.

This is a longitudinal study in which participants that have been confirmed by a National Health Service (NHS) swab test as COVID-19 positive will be asked to provide faecal and saliva samples, and complete short health/lifestyle questionnaires at the time of sampling (referred to as a sample set). The number of sample sets collected from any participant will be dependent on how long the SARS-CoV-2 virus persists within the stool. The investigators aim to collect a minimum of 4 and a maximum of 8 sample sets, and will target all COVID-19-positive subjects, with the exception of those severally ill (e.g. in the intensive care unit (ICU)). The investigators aim to recruit a minimum of 100 and up to 200 participants. To obtain the desired numbers, it may be necessary to continue recruitment during any further United Kingdom (UK) COVID-19 infection peaks.

The aim of this study is to evaluate the role of the topical corticosteroids nasal spray (mometasone furoate nasal spray) in improving anosmia in patients recovered from COVID-19 infection.

Randomized, Parallel Group, Active Controlled Trial

The purpose of the proposed pilot study is to determine if core warming improves respiratory physiology of mechanically ventilated patients with COVID-19, allowing earlier weaning from ventilation, and greater overall survival.

This randomised trial aims to assess the role of sildenafil in improving oxygenation amongst hospitalised patients with COVID19.

This study aims to collect convalescent plasma and use it as experimental treatment in critically ill Covid-19 patients in order to reduce mortality and length of stay in intensive care unit.

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.

This study will evaluate the antihelmintic drug, Niclosamide, as a potential treatment for mild to moderate coronavirus disease 2019 (COVID-19).
