Active clinical trials for "COVID-19"

This is a phase II study to test adenosine efficacy for down-regulation of the overwhelming inflammation of COVID-19 in the lungs as reflected by clinical recovery of lung function; resolution of clinically relevant markers of lung function, and resolution of systemic markers of inflammation and coagulation.

The CVP-COVID19 registry is both a retrospective and prospective study design in order to identify predictors of cardiovascular disease progression and mortality for COVID-19. The registry enrolls consecutive patients with positive microbiological tests for SARS-CoV-2 admitted to an academic hospital in northern Italy for worsening of COVID-19 symptoms. The study does not test any new diagnostic or therapeutic approach. Patients are treated according to good clinical practice. Patients characteristics, including medical history (with particular attention to cardiovascular and pneumological risk factors), features of physical examination, results laboratory and radiological tests and treatments (pre- and in-hospital) are related with patient outcome. Logistic analysis (univariate, multivariate and propensity) are performed in order to identify factors associated with disease progression. Primary endpoint: mortality.

Introduction. Some issues remain to be elucidated about SARS-CoV-2 infection to plan prevention interventions based on scientific evidence, such as the actual prevalence of infection including subclinical and seroconverted cases, the reasons for the different spread and severity of the infection in different subjects and geographical areas as well as the impact of the COVID-19 crisis on the health of healthcare professionals and in the general population. The aims of this project are: (i) to estimate and compare the real prevalence of the SARS-CoV-2 infection and seroconversion in two populations at high or low risk of infection,in Lombardia region and Molise region, respectively; focusing on subgroups at higher risk such as healthcare workers (HCWs); (ii) to estimate the incidence of burnout and post-traumatic stress disorder in HCWs; (iii) to identify factors associated with SARS-CoV-2 infection positivity and to follow up its mid-term effects on health. Methods. Participants will be randomly selected from the general population of both territories and from the HCWs list of the two healthcare facilities involved. SARS-CoV-2 IgG and IgM blood levels will be measured and anamnestic data will be collected through computerized tools. Prevalence of currently or previously infected subjects and their disease status and severity will be estimated and the association with potential risk factors will be analyzed through multivariable regression analyses. Expected results. The study will identify the burden of the infection in the general and HCWs populations. It will also identify the determinants of differences in the spread and severity of the infection, to hypothesize new preventive or therapeutic interventions. This study will provide a basis for monitoring the progress of the infection and its medium-term health consequences, Finally it will allow planning future studies, through analyses in biological samples which will be collected in dedicated biobanks.

NAPKON-HAP is the deep phenotyping platform of the National Pandemic Cohort Network (NAPKON) in Germany. NAPKON is a data and biospecimen collection of patients with COVID-19 and is part of the University Medicine Network (NUM) in Germany. The primary objective of the study is to provide a comprehensive collection of data and biosamples for researchers from national consortia and for participation in international research collaborations for studying COVID-19 and future pandemics. Data is collected from patients with COVID-19 three times per week during their hospitalization and at follow-up visits after hospital discharge 3, 6, 12, 24, and 36 months after symptom onset. Data include epidemiological and demographic parameters, medical history and potential risk factors, documentation of routine medical procedures, and clinical course, including different patterns of organ involvement, quality of care, morbidity, and quality of life. Moreover, extensive serial high-quality bio sampling consisting of various sample types is performed to allow deep molecular, immunological, and virological phenotyping. Patients not requiring Intensive Care Unit (ICU)/ Intermediate Care (IMC) treatment will receive 7 and patients requiring ICU/IMC treatment will receive 16 full-phenotyping visits including sampling for biobanking. During hospitalisation the planned blood sampling rate in total is 35 ml at each visit. The total amounts and/or sampling dates may differ according to the ethics committee's regulations for different study centers. At follow-up visits, the clinical assessment includes an update of the medical history and recent medical events from which additional clinical data is collected (i.e. outpatient CT-scans, echocardiography, external laboratory data). Clinical symptoms are recorded and a physical examination will be performed. Vital signs are recorded and routine blood testing and biosampling is continued. Quality of life is measured with patient-reported outcome questionnaires. Follow-up visits at months 3 and 12 are "deep phenotyping" visits with a comprehensive and detailed set of examinations. In the following visits at months 24 and 36, only examinations with pathologic results from the last deep phenotyping visit at month 12 will be performed. A shorter follow-up visit to record quality of life, recent medical events and with a reduced number of examinations focusing on cardiorespiratory performance will take place at month 6. In case of relevant medical events, new medical information or changes in the participant´s health status, an unscheduled visit can take place anytime within the entire study period. Data collection during follow up includes standardized quality of life assessment including PROMIS® (Patient-Reported Outcomes Measurement Information System). The pulmonary characterization will include body plethysmography, diffusion capacity, respiratory muscles strength measurement, spiroergometry, capillary blood gas analysis and lung imaging studies (low-dose Computed Tomography (CT), Magnetic Resonance Imaging (MRI) of the lung). Cardiological phenotyping includes echocardiography, electrocardiogram (ECG), 24h-ECG, 24h-blood pressure monitoring, stress cardiac MRI and pulse wave analysis. Neurocognitive testing includes brain MRI, electroencephalogram (EEG), somatosensory testing, refractometry (Visit 3 and 12 months), physical activity test, neurocognitive tests, somatosensory phenotyping, taste- and smell-test. Endocrinological phenotyping will incorporate Advanced Glycation Endproducts (AGE) reader, continuous glucose monitoring for 14 days, Air Displacement Plethysmography (ADP) or bioelectrical impedance analysis (BIA).

The purpose of the study is to describe disability following hospitalization in people of working-age surviving COVID-19.

This project aims to monitor the side effects of COVID-19 vaccines worldwide actively. The primary objectives of the project include a) to estimate the prevalence of each local and systemic side effect of each COVID-19 vaccine among healthcare workers (HCW), old adults over +65 (OA), and schoolteachers (ST); b) to evaluate the potential demographic and medical risk factors for side effects frequency and intensity; c) to evaluate the long-term consequences of COVID-19 vaccines. The secondary objectives include a) to evaluate the relative safety of COVID-19 vaccines compared to each other; b) to evaluate the impact of palliative drugs used by the recently vaccinated individuals on their short-term side effects resolution.

The novel coronavirus infection (COVID-19) caused by the SARS-CoV-2 virus is now a pandemic and has culminated major morbidity and mortality globally. Studies have shown that patients with underlying type 2 diabetes mellitus (DM), obesity, old age and hypertension had a higher risk of developing severe COVID-19 infection and mortality related to COVID-19.Emerging evidence has shown that gut microbiota plays an important role in the pathogenesis of COVID-19.

Collection of SARS-COV-2 Secretions and Serum for Countermeasure Development (aka ClinSeqSer) is an observational study to understand natural history of SARS-COV-2 infections among special populations and characterise post-covid morbidity through immune response, virus genome sequencing, cytokine response, and virus shedding. Given the descriptions of infection course of patients over the outbreak of 2003 (SARS-Cov01) and since January 2019 in China and Europe, and now worldwide: Acutely infected patients shed virus that could be of major interest to characterize (viral quantification, characterization of virus shedding -of infective and of non-infective virus) the former reflecting/predictive of severity of disease and the latter reflecting extent/source of contagiosity. Convalescent infected patients develop a specific anti-virus antibody response that is (likely) protective and therefore suits the preliminary requirement for the potential benefits of the convalescent patient plasma therapeutic infusion approach. In addition, long term effects of COVID-19 commonly known as long-haulers remains clinically unclear. Thousands of patients have now been diagnosed with COVID-19 in Louisiana (444,000 cases, 10,122 deaths, 2.2% mortality in Louisiana (LA), as of March 2021), and numerous patients are now also complaining of post-acute sequelae of SARS-CoV-2 (PASC). The investigators want to further clarify questions surrounding rational confinement duration and therapeutic approach by collecting plasma of convalescent patients to identify optimal antibody titer by ELISA, specificity of naturally occurring inflammatory (protein/antibody and RNA) response, and possibly test in vitro antibody neutralization activity.

Background: People with COVID-19 have varying degrees of illness. It can range from no or mild symptoms to critical illness and death. Some people with COVID-19 have long-term effects regardless of the severity of their disease initially. Researchers want to learn more to see if they can better predict where a person may fall on the illness spectrum. Objective: To follow and record symptoms of COVID-19 to see how it progresses in people and why some people stay sick longer than others. Eligibility: People ages 18-65 who received a COVID-19 positive test result in the 72 hours before their enrollment in the study. Design: Participants will complete a 30-minute baseline survey. They will answer questions about themselves and their health. Participants will get a digital wristband and temperature sensor in the mail. They will get instructions on how to set up and wear the devices. They will download a mobile application on their phone. The app will collect data from the devices. Participants will wear the wristband and sensor every day for the first month. Then they will wear the devices for a total of 40 days over the next 5 months. On the days they wear the devices, they will answer a 2-question health survey via the app. Participants will answer a 20-minute online survey about their health every 30 days. If participants are hospitalized, a family member or close friend will be asked to complete a brief 7-minute online survey about their hospital stay and treatment. Participants will be sent alerts and reminders throughout the study. Participation will last for 6 months.

Severe Acute Respiratory Syndrome (SARS) Coronavirus (CoV) 2 infection and the associated coronavirus disease 2019 (COVID-19) are the most recent international health threat challenging our ability to protect populations, to avoid severe outcomes and to understand both the population dynamics of this new condition and the breath of individual responses. Gathering information on the clinical course of the disease and the risk of transmission is essential to design effective therapeutic solutions and preventive measures. The aim of the study proposed, to be carried out at University Hospital Center of "São João" (CHUSJ), is to recruit and follow-up a cohort of patients diagnosed with SARS-CoV-2 infection, to evaluate the clinical course of SARS-CoV-2 infection and COVID-19 cases, to identify prognostic factors and to measure the risk of reinfection. Additionally, researchers intend to characterize the patients and household contacts to describe the dynamics of infection, to calculate household infection attack rate, and to perform the genetic sequencing of SARS-CoV-2 to understand determinants of disease course (namely long-term effects) and risk of household transmission. A sample of participants, identified during the process of evaluation of symptomatic individuals, at the same institution, and negative for SARS-CoV-2 will be selected as negative controls. Participants will be consecutively recruited and the study is expected to enroll patients as long as the pandemic remains. Information will be gathered based on clinical individual charts, hospital data-bases (example: for administrative data) and individual computer assisted interviews to be performed at pre-defined intervals (3, 12 and 24 months) or according to clinical needs. The project was approved by the local Ethical Committee and the Data Protection relevant authorities.
