Active clinical trials for "Severe Acute Respiratory Syndrome"

In this prospective observational study, a quantitative and qualitative analysis of antibiotic prescriptions for presumed respiratory tract (super)infection in patients hospitalized on COVID-19 wards will be made. Drivers of antibiotic prescription for presumed respiratory tract infection in patients suspected of being infected with COVID-19 or with definite COVID-19 infections will be identified.

Project is designed as a comprehensive population-based epidemiological study in Upper-Silesian Conurbation (Poland) aiming at: analysis of available data on incidence and mortality due to COVID-19 and estimation of the occurrence of viral infection SARS-CoV-2 as revealed by the results of serological test (ELISA: IgM, IgG), with assessment of risk factors. The project's objectives are: to assess incidence and mortality due COVID-19 according to sex, age and coexisting diseases; to determine the level of potential "underdiagnosis" of the magnitude of COVID-19 mortality using vital statistics data for Upper-Silesian Conurbation; to assess the prevalence of SARS-CoV-2 based on the level of seropositivity in Upper-Silesian Conurbation; to identify host-related and environmental risk factors if the infection. Analysis of existing data will include monthly records on incidence and mortality over the period 01.01.2020-31.12.2020 and comparison of the findings with the monthly records of 2018 and 2019, for the same population. Cross-sectional epidemiological study will be located in three towne (Katowice, Sosnowiec, Gliwice). In each town a representative age-stratified sample of 2000 subjects will undergo questionnaire assessment and serological examination performed by serological test. The project corresponds with analogous population-based studies on COVID-19 in a number of countries and responds to the WHO recommendation in that field.

Patients older than 18 years of age, with COVID-19 related ARDS (C-ARDS) hospitalized in the ICU and invasively mechanically ventilated will be included in the study. This is an observational cohort study. After informed consent by the next of kin, and within the first 72 hours of invasive mechanical ventilation a blood and a Broncho Alveolar Lavage Fluid (BALF) sample will be collected. If the patients remain invasively mechanically ventilated a second and third blood and BALF sample will be collected every 7-10 days.

The COVIDOUT study will prospectively investigate the serological immunity of outpatient cancer patients to evaluate the prevalence of previous severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and dependency of serological immunity on systemic (chemo)therapy after COVID19 disease as well as after vaccination.

SETANTA study will investigate the incidence of cardiac abnormalities as assessed by cardiac magnetic resonance imaging in unselected patients after acute SARS-CoV-2 infection and correlation with immunological response and biomarkers of coagulation.

Electrocardiographic (ECG) evaluation of patients with severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infection. The present study involves three different phases of evaluation of the ECG traces of hospitalized patients with SARS-CoV-2 infection. Phase 1: it is proposed to collect and retrospectively analyze the ECGs of hospitalized patients with severe SARS-CoV-2 infection which led to invasive ventilation or patient death as a consequence and, if available, also possible troponin dosage; Phase 2: aims to collect and analyze the ECGs of consecutive hospitalized patients with SARS-CoV-2 infection and evaluate their relationship with the course of the disease, cardiac involvement and prognosis; Phase 3: it is proposed to repeat ECG and to carry out echocardiogram to patients with SARS-CoV-2 infection after 3 months from hospital discharge by simultaneously performing, if deemed clinically indicated, also cardiac magnetic resonance. In this phase, any evolutions of ECG alterations of the acute phase will be described and the relationship with cardiac involvement will be assessed.

The Malaysian COVID-19 Anosmia Study is a nationwide multicentre observational study to investigate the prevalence and characteristics of olfactory and gustatory/taste disturbances in COVID-19 infection in Malaysia, and to evaluate the predictive value of screening for these symptoms in COVID-19 infection. This study consists of two phases: the first phase is a cross-sectional study and the second phase is a case-control study. The case-control study is described here (the cross-sectional study is described in a separate ClinicalTrials.gov record).

The role of ECMO in the treatment of patients with severe COVID-19 (Acute Respiratory Distress Syndrome (ARDS) and/or acute refractory heart failure) is not yet known. The present study will aim to report the results of the ECMO management of the most severe forms of COVID-19 through the first French ECMO registry.

This study will evaluate the associations between vascular parameters and clinical outcomes in patients hospitalized with COVID-19. The vascular function and structure of individuals with COVID-19 admitted to the General Hospital of the University of Sao Paulo will be assessed in the first 72 hours of hospitalization. Then, participants will be followed up until hospital discharge/death. Logistical regressions will be run to evaluate if vascular function/structure can predict ICU admissions, intubation, thrombosis or death.
