Active clinical trials for "COVID-19"

Multicenter retrospective and prospective observational study based on the collection of sequential anonymized data from principal Italian ITP centers, to describe the clinical course of ITP patients becoming infected by SARS-CoV-2 and of COVID-19 patients developing de novo ITP.

The NanoCOAT study is a multi-center, prospective, non-randomized, feasibility, observational, non-significant risk study. The NanoCOAT study will enroll a minimum of 10 and a maximum of 100 subjects in a potential for a multi-site in order to collect data and analyze physiological and biometric trends due to Covid-19.

The data were retrospectively collected during the first and the second wave of epidemic in COVID-19 patients with Severe Acute Respiratory Syndrome Coronavirus 2, at the moment of intensive care unit admission and during the in intensive care unit staying.

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.

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.

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.

Gabon is the 3rd country most affected by COVID-19 behind Cameroon and Democratic Republic of Congo in Central Africa, with 8860 cases and 54 deaths in critically ill patients, since the first confirmed case of COVID-19 on the 10th of March 2020 (https://africacdc.org/covid-19/). Most of the individuals infected by SARS-CoV-2 are asymptomatic and they represent a major source of viral spread. To date, African countries have been less affected by deaths caused by the Covid-19 pandemic compared to other countries. It is currently unknown why Africa has avoided more deaths and appears to not simply be due to a lack of testing, since the overall death rate has not increased. Better quality data on seroprevalence in different African regions and proven explanations of the differences between Africa and other continents, are urgently needed. The aim of this study is to learn about the proportion of people after a first pic of transmission, who have been exposed to COVID-19 in Gabon by testing for plasma antibodies to the SARS-CoV-2 virus. The overall goal of this study is to examine the trend of specific anti-SARS-CoV-2 antibodies in Gabonese population.

A multicenter observational, prospective cohort study that consisted of a large-scale data source of hospital ICU admissions and patient-level clinical data in Spain. The main objective is to develop a national database belonging to SEMICYUC (Spanish Society of Critical Care) to describe epidemiological and clinical characteristics and risk factors related to ICU mortality in critically ill patients admitted to ICU due to severe COVID-19 in Spain.

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.

Patients with severe Coronavirus Disease 2019 (Covid-19) pneumonia depending on mechanical ventilation are at risk of superinfections, especially infections of respiratory tract. This multicententer prospective observational study is focused on early diagnosis of respiratory tract superinfections and identification of risk factors (immunosuppressive therapy,...). Investigators will use bronchoalveolar lavage fluid (BALF) for Polymerase Chain Reaction (PCR) detection of pathogens and antigenic detection of mycoses. This project can support the routine use of BALF and PCR diagnostics for early detection of pathogens. Data will be compared with historical cohort of patients without routine BAL.
