Active clinical trials for "COVID-19"

The present study aimed to evaluate the accuracy of MSCT chest in the detection of COVID-19 cases and to correlate its diagnostic performance with that of the clinical presentation and CBC indices; using RT-PCR assays as a gold standard.

The coronavirus (COVID-19) pandemic has created a significant strain on health care resources across the world for managing critically ill patients. Emerging reports from China, South Korea and Italy have reported varying incidence of acute kidney (AKI) ranging from 5-15% with a mortality of 60-80% however there is no systematic assessment of the risk factors, recognition, course and outcomes in patients with and without kidney disease whose course is complicated by AKI1-4. Patients with underlying CKD, immunosuppressed patients with renal transplants and ESKD patients are at high risk for COVID-19 infection and there is limited information on the effect of COVID-19 on the course and outcomes of these patients. The requirement for renal support including IHD, CRRT and sorbent based therapies has been variable and has contributed to the intense pressure on the nephrology and critical care providers for delivering these therapies. As the COVID-19 pandemic expands in the USA and abroad, there is an intense need to understand the epidemiology of the disease and the resources needed for renal support to inform clinical management and public health interventions. In this study, the investigators aim to investigate health care facilities across the world (hospital wards, ICU, outpatient clinics, nursing homes, healthcare centers) to draw a global picture of incidence, risk factors, resources available for treatment and prognosis of acute and chronic kidney disease in patient with COVID 19 confirmed infection. The aim is to identify trends in patients with acute and chronic kidney disease, determine its incidence, treatment and outcomes in different settings across the world. This information will be used to develop and implement educational tools and resources to prevent deaths from AKI and progression of CKD in this and following pandemics.

Coronavirus (COVID-19) is a respiratory disease caused by a newly discovered coronavirus, SARS-CoV-2. Several recent papers on the pandemic recognized obesity as a risk factor for the COVID-19 infection. Therefore, an effective treatment for obesity even during COVID-19 outbreak is needed. Bariatric surgery, is considered an effective treatment in the reduction of obesity-related comorbidities and mortality risk. However, during Covid-19 phase 1 (lockdown) the near totality of elective non-oncologic procedures, including bariatric surgery, has been postponed, and all the outpatients' visits too. Therefore, phase 1 led to completely change the way of managing the pre-operative multidisciplinary visits considering the hospital limitation access and the restriction. In the present study the investigators explored the use of telemedicine as a possible strategy to face this new situation. Specifically, this study aims to test the efficacy of an online structured protocol based on pre-operative multidisciplinary assessment using telemedicine instruments. In particular, the primary end point is to test the feasibility of a telematics pre-operative work-up. The secondary end points are evaluating patient's compliance and satisfaction to the online assessment.

The XPHI-COVID19 randomized study aims to investigate the mechanisms of moral judgements in a population of caregivers, using a survey, with the results to the Oxford Utilitarianism Scale as primary outcome.

Describe the immune response of patients affected by SARS-CoV-2, including an assessment of the types of antibodies elicited by the infection, specifc antibody titers for the different isotypes, evolution of the antibody response over time, protective efficacy and immune correlates of protection. investigate genetic determinants of Covid-19 and of the imune response to this condition. Finally, the study will investigate secondary infection rate and its determinants among household contacts of Covid-19 patients.

Little is currently known about the immediate and long-term effect of COVID-19 on lung ventilation (delivery of air to the lungs) and lung perfusion (delivery of blood to the lungs). Some people who survive COVID-19 may have lung ventilation and/or perfusion injury that persists following COVID-19 recovery. This lung injury may be related to inflammation in the lung, breathlessness, exercise limitation and reduced quality of life. Therefore, towards the goal of understanding the effects of COVID-19 on lung health, the purpose of this study is to characterize and understand the clinical relevance of COVID-19 related lung ventilation and perfusion injury and associated inflammatory status, ≤4 weeks and 6-months following COVID-19 recovery in an asthmatic and healthy population. To do this, an asthmatic and healthy population who have, and have not, been previously diagnosed with COVID-19 will be studied.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a new coronavirus responsible for the pandemic called coronavirus disease 2019 (COVID-19), which appeared in China in December 2019 and which has spread rapidly around the world. Even if in the vast majority of viral infection results in a mild illness, it can also progress to a severe form with sometimes fatal consequences. Indeed, clinical worsening, between the 7th and 10th days of the onset of symptoms, has been widely described since the start of the pandemic. This manifests itself at the biological level by hyperinflammation (VS, CRP, ferritin), coagulopathy (elevation of D-dimers, sometimes disseminated intravascular coagulation) and cell lysis (CPK, LDH). At the same time, it was observed high levels of pro-inflammatory cytokines (IL-1β, IL-6, TNF-α, IL-18), suggestive of a cytokine storm, and the first studies on therapeutic management targeting these cytokines are currently underway in COVID-19. Such a profile strongly recalls on the one hand the cytokine release syndrome (CRS, observed in CAR-T cell therapy in malignant hematology), and on the other hand the lymphohistiocytic activation syndrome (SALH). Systemic diseases, such as adult Still's disease and its pediatric side, can also be complicated by a cytokine storm, known as macrophagic activation syndrome (SAM, equivalent to secondary SALH). Under all these conditions, IL-1β, IL-18, IFN-γ and IL-6 seem to be key mediators of hyperinflammation. Plasma ferritin is a biological marker of inflammation, long known, associated with various infectious, hematological and immunological conditions. An increase in ferritin levels has in particular been associated with an unfavorable development in certain infections such as influenza and certain authors have moreover shown an association between plasma ferritin and the evolution towards ARDS or death in patients. Its dosage is also used as a diagnostic tool for SAM, and could make it possible to differentiate the latter from severe sepsis in intensive care. Some authors have also noted it as a prognostic factor in Kawasaki disease or CRS. The plasma dosage of ferritin, associated with that of its glycosylated fraction, could therefore be a diagnostic (difference between SAM and severe sepsis in intensive care), prognostic (evolution towards ARDS, mutation in intensive care, mortality) and therapeutic (indication of preemptive treatment with an inhibitor of IL-1 or IL6) in patients infected with SARS-CoV-2. The objective of this study is to retrospectively assess the prognostic value of ferritin and glycosylated ferritin in SARS-CoV-2 infection in hospitalized.

A clinical and experimental study will be carried out in which the clinician will investigate the PCR of the virus early in different body fluids (blood, semen, urine, saliva) and monitor its experimental clearance and evaluate in vitro diagnostic tests and inhibitory factors of viral proliferation.

The identification of patients with genitourinary tumors who suffer from the infection by the Serious Acute Respiratory Syndrome Corona-Virus 2 (SARS-CoV-2) virus can represent multiple benefits both for themselves and for health professionals and the health system itself. We would be able to know more precisely the clinical evolution of these type of patient, to know their prognosis and being capable to select the most appropriate treatment modality for future pandemics. SOGUG-COVID is an observational prospective-retrospective trial purely epidemiological, that aims to describe the population with genitourinary tumors (urothelial cancer, prostate cancer, testicular cancer and kidney cancer) infected by COrona VIrus Disease 19 (COVID-19) treated in Spanish hospitals, learn about the clinical presentation, therapeutic evolution and prognosis of said intercurrent infectious process, as well as its possible relationship with different clinical and therapeutic factors.

Patients with neurological or psychiatric symptoms or pre-existing disease will be sampled (blood for serum and DNA or saliva for DNA) at inclusion and at M6 (blood) and M12 (blood) depending on their pathology. Sampling will be done either at hospital if patient is on site for routine care or at home if no consultation is scheduled at hospital.
