Filter by:The investigators aim to characterise Coronavirus Disease 2019 (COVID-19) in every age group. On the one hand, emphasis is put on the initial presentation, clinical course, outcome and the therapy used. On the other hand further investigations regarding viral and bacterial coinfections, and response of the immune system will be conducted. This study should serve to improve the understanding of COVID-19, to identify risk factors for a severe clinical course and to obtain further insights into pathophysiology of this new infectious disease.
Specific Aims: 1. The investigators will prospectively evaluate and analyze changes in the appearance of the lungs and heart through serial acquisition of focused point-of-care ultrasound images in a cohort of patients with or under investigation for COVID-19. 2. The investigators will correlate changes noted in ultrasound with clinical course and diagnostic evaluation to ascertain whether changes on ultrasound could improve care through earlier diagnosis or identification of patients at high risk of disease progression.
The outbreak of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been declared a public health emergency of international concern. Hospitalized COVID-19-positive patients requiring ICU care is increasing along with the course of epidemic. A large number of these patients developed acute respiratory distress syndrome (ARDS) according to current data. However, the related hemodynamic characteristic has so far been rarely described.
Coronavirus disease 2019 or COVID-19 is a highly contagious infectious disease. Symptoms of the disease are non-specific (fever, cough, dyspnea and fatigue), common with many seasonal viruses, which complicates the diagnosis. For mild forms, which represent the vast majority of cases, hospitalization is not necessary and treatment is symptomatic. However in more severe cases, hospitalization is required and sometimes even admission to an intensive care unit. Several diagnostic tests are already available, but they require, in all cases, the intervention of qualified health personnel to carry out the sample, which includes a risk of contagion and an expensive and time-consuming laboratory analysis and reagents. These tests are therefore not very suitable for massive screenings. We want to evaluate the performance of a detection test performed on a salivary sample in the diagnosis of SARS-CoV-2. This test will be non-invasive, performed without any analytical device and will restore its qualitative result "infected versus non-infected" in less than 1 hour (30min objective).
This is a three-arm randomized trial comparing the efficacy of single agent hydroxychloroquine to the combination of hydroxychloroquine and azithromycin, and to a delayed hydroxychloroquine regimen, which will serve as a contemporaneous Day 1-6 supportive care control, in eliminating detectable SARS-CoV-2 on day 6 following the initiation of treatment in order to determine which regimen is more effective.
Our long-term goal is to protect the health care workforce (HCW) caring for SARS-CoV-2-infected patients, their families, communities, and the general population. Our specific objective is to rapidly establish a prospective cohort to characterize the factors related to viral transmission and disease severity in a large healthcare system. We addressed this hypothesis by recruiting and longitudinally following 546 HCW and a comparison group of 283 non-HCW within a large academic health system, Rutgers Biomedical and Health Sciences (RBHS). By intensively following participants over a several year period (2020-2024) and collecting serial biospecimens (nasopharyngeal/throat swabs, blood, and saliva) and questionnaire data at multiple time points, we will uniquely characterize SARS-CoV-2 transmission and risk factors for COVID-19 among HCW and our larger academic community.
Rationale: The current SARS-CoV-2 pandemic has a high burden of morbidity and mortality due to development of the so-called acute respiratory distress syndrome (ARDS). The renin-angiotensin-system (RAS) plays an important role in the development of ARDS. ACE2 is one of the enzymes involved in the RAS cascade. Virus spike protein binds to ACE2 to form a complex suitable for cellular internalization. The downregulation of ACE2 results in the excessive accumulation of angiotensin II, and it has been demonstrated that the stimulation of the angiotensin II type 1a receptor (AT1R) increases pulmonary vascular permeability, explaining the increased lung pathology when activity of ACE2 is decreased. Currently available AT1R blockers (ARBs) such as valsartan, have the potential to block this pathological process mediated by angiotensin II. There are presently two complementary mechanisms suggested: 1) ARBs block the excessive angiotensin-mediated AT1R activation, and 2) they upregulate ACE2, which reduces angiotensin II concentrations and increases the production of the protective vasodilator angiotensin 1-7. In light of the above, ARBs may prevent the development of ARDS and avert morbidity (admission to intensive care unit (ICU) and mechanical ventilation) and mortality. Objective: To investigate the effect of the ARB valsartan in comparison to placebo on the occurrence of one of the following items, within 14 days of randomization:1) ICU admission; 2) Mechanical ventilation; 3) Death. Study design: A double-blind, placebo-controlled 1:1 randomized clinical trial Study population: Adult hospitalized SARS-CoV-2-infected patients (n=651). Intervention: The active-treatment arm will receive valsartan in a dosage titrated to blood pressure up to a maximum of 160mg b.i.d. and the placebo arm will receive a matching placebo also titrated to blood pressure. Treatment duration will be 14 days or up to hospital discharge < 14 days or occurrence of the primary endpoint if < 14 days. Main study endpoint: The primary study endpoint is the occurrence within 14 days of randomization of either: 1) ICU admission; 2) Mechanical ventilation; 3) Death.
This is a pragmatic, randomized, open-label, incomplete factorial with nested randomization clinical trial evaluating the efficacy and safety of two potential treatments for hospitalized patients with confirmed SARS-CoV-2 infection. Participants who are hospitalized and have a positive nucleic acid amplification test for SARS-CoV-2 will undergo an initial randomization in a 1:1 ratio to one of the following regimens: Arm 1: Standard of care alone Arm 2: Standard of care plus hydroxychloroquine Participants who meet eligibility criteria to receive azithromycin will undergo a second randomization in a 1:1 ratio to receive additional concurrent therapy. This will effectively result in four treatment groups: 1. Standard of care alone 2. Standard of care plus hydroxychloroquine 3. Standard of care plus azithromycin 4. Standard of care plus hydroxychloroquine plus azithromycin
This is an double-blind, randomized, placebo controlled phase III study in hospitalized subjects with confirmed SARS-CoV-2.
This study will assess the efficacy of hydroxychloroquine in reducing the severity of symptoms in patients with COVID-19
