Active clinical trials for "COVID-19"

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 COVID-19 infection affects humans differently. While some recover quickly and fully, others develop serious illnesses and late complications. The term late complications describe symptoms that last for 12 weeks or longer after COVID-19 infection is detected. The aim of the present project is to investigate whether it is possible to identify genetic factors that occur more frequently in people suffering from COVID-19 late complications than in those who do not develop late complications. The investigators aim to develop a genetic profile that identifies individuals at high risk for late complications of COVID-19. Number and nature of late complications will be analyses to identify patterns in the incidence of late complications associated with certain genetic traits. The study is designed as a case-control study and is expected to include 500 subjects between 18 and 65 years of age who at least 12 weeks ago tested positive for COVID-19; 250 who suffer from late complications and 250 who have fully recovered.

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

Patients hospitalized for COVID-19 may need intensive care (e.g. mechanical ventilation) during hospitalization. Some risk factors are already known but better targeting of such patients is still needed, at least because existing risk factors are not strong enough to provide an accurate prediction. Care organization would benefit for such a predictive tool. Oropharyngeal and gut microbiota could potentially fill a significant gap in predictive performances. The investigators therefore propose to sample 200 patients (oropharyngeal and rectal swab) admitted in infectious disease department at Bichat Hospital and at high risk of needing intensive care during hospitalization. The investigators plan to perform metagenomic sequencing and bioinformatic analysis of these samples to characterize the diversity of bacterial species present in the oropharynx and the gut and to identify new factors associated with the need for intensive care. Aside metagenomic analyses, The investigators will perform semi-quantitative cultures of the oropharyngeal and gut microbiota to identify and quantify pathogens in order to predict the risk of bacterial infections in COVD-19 patients. For patients transferred in intensive care unit, The investigators will to perform another series of samples to better characterize the evolution of microbiota during mechanical ventilation and identify factors associated with the risk of developing a ventilator-associated pneumonia. Microbiota data will be considered together with the host genotype, the viral sequence and a deep immunological profiling to identify the main determinants of the evolution toward severity of COVID-19.

Administration of systemic corticosteroids for patients with severe forms of severe acute respiratory syndrome(SARS-Co-2) infection are recommended by several guidelines. In the very beginning of SARS-Co-2 pandemic the early recommendation by professional organization was against routine use of corticosteroids for patients with coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome (ARDS), despite previous data and clinical practice for patients with refractory or severe form of ARDS.

COVID-19 is a novel disease caused by SARS-CoV-2 that primarily affects the lungs but also various other organs of the body already in early stages of the disease. Due to the multiple organ involvements in the acute phase, it is conceivable that - in a significant proportion of patients - longterm sequels in various organ systems might occur, thereby impacting the individual's health status and quality of life; and posing a relevant burden to the resources of the health care system Assessment of SARS-CoV-2-longterm morbidity and sequels on the population level: In order to identify and treat these sequels in a timely fashion and to get a sense of the prevalence of such SARS-CoV-2 sequels on the population level, it is important to collect follow-up data and to comprehensively re-examine a population-representative sample of SARS-CoV-2 infected individuals. Within the COVIDOM study we will conduct deep clinical and biochemical phenotyping in population-representative samples in Germany. This will allow novel insights into disease pathogenesis and chronicity of virus infections.

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.
