Active clinical trials for "COVID-19"

The research will be retrospective, and will include all patients who were admitted during 2020 and 2021 in the COVID-19 ICU of University Hospital Center Osijek due to pneumonia caused by the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The association of chest x-ray infiltrate evolution with changes in laboratory inflammatory parameters and respiratory function parameters will be examined.

This is a combined retrospective and prospective, longitudinal, observational meta-cohort of individuals age 0-25 years who will enter the cohort with and without SARS-CoV-2 infection at varying stages before and after infection. Individuals with and without SARS-CoV-2 infection and with or without PASC symptoms will be followed to identify risk factors and occurrence of PASC. This study will be conducted in the United States and participants will be recruited through inpatient, outpatient, and community-based settings. Study data including age, demographics, social determinants of health, medical history, vaccination history, details of acute SARS-CoV-2 infection, overall health and physical function, and PASC symptoms will be reported by participants or collected from the electronic health record using a case report form at specified intervals. Biologic specimens will be collected at specified intervals, with some tests performed in local clinical laboratories and others performed by centralized research centers or banked in the Biospecimen Repository. Advanced clinical examinations and radiologic examinations will be performed at local study sites with cross-site standardization.

Individuals with and without SARS-CoV-2 infection and with or without Post-Acute Sequelae of COVID-19 (PASC) symptoms will be followed to identify risk factors and occurrence of PASC. This study will be conducted in the United States and subjects will be recruited through inpatient, outpatient, and community-based settings. Study data including age, demographics, social determinants of health, medical history, vaccination history, details of acute SARS-CoV-2 infection, overall health and physical function, and PASC symptom screen will be reported by subjects or collected from the electronic health record using a case report form at specified intervals. Biologic specimens will be collected at specified intervals, with some tests performed in local clinical laboratories and others performed by centralized research centers or banked in the Biospecimen Repository.

Observational Study of the Association of Immunological and Inflammatory Biomarkers in COVID-19 Naïve and Infected Participants and Severity of Disease. Thirty naive and 30 COVID positive participants will have a blood sample taken after informed consent and be assessed for COVID symptoms according to WHO classification. Participants will be followed monthly for 6 months. At each contact, participants will be assessed for COVID symptoms and progress since the previous visit.

The project is designed as a cross-sectional study and aims to examine long-term consequences of coronavirus disease 2019 (COVID-19) for selected bio-behavioural parameters while taking the disease course severity into account.

Determining whether in the mouth there are differences between the participant groups in the nature and activity of mucosal innate immunity, in immune responses to SARS-COV2 antigens, or in the oral microbiome

The purpose of this study is to learn more about how to better track smell recovery in people who have been infected with the SARS-CoV-2 virus (which causes COVID-19). Many people who have been infected by this virus develop changes in their sense of smell (olfaction). We are interested in measuring smell function objectively via smell cards that test odor intensity, identification, and discrimination. Objective and precise olfactory testing that can be performed in the convenience of one's home will help identify people with smell loss after infection by SARS-CoV-2. We will use results from this test to better understand the relationship between SARS-CoV-2 infection and recovery of olfactory function and to learn whether the AROMHA longitudinal smell test is a reliable olfactory function tracking tool to quantify smell loss in the context of COVID infection. These results may inform the design of therapeutic clinical trials to accelerate the recovery of smell function.

The primary objective is to assess the ability of COVID-19 IgG and IgM assays to detect an immune response in COVID-19 patients in the Henry Ford Health System (HFHS), both during hospitalization and over the following 12 months.

COVID-19 is associated with acute pulmonary and cardiac injury. To better understand the degree and severity of cardiopulmonary injury as well as short and long-term sequelae of COVID-19 infection, this study will perform longitudinal study in patients who had recent known diagnosis of COVID-19.

Performance of the LumiraDx SARS-CoV-2 Ag assay will be assessed by comparison to a reference method.
