Active clinical trials for "COVID-19"

Primary endpoints Incidence of symptomatic and asymptomatic infection with SARS-CoV-2 and other respiratory viruses as determined by molecular (e.g. PCR) and serological testing Associations between the magnitude and quality of mucosal and serum antibody responses to SARSCoV- 2 and protection from infection with SARS-CoV-2 Associations between the magnitude and quality of T cell responses to SARS-CoV-2 and protection from infection with SARS-CoV-2 Secondary endpoints Secondary attack rate and household cumulative infection rate with SARS-CoV-2, influenza, RSV, and other respiratory viruses Seroincidence and seroprevalence of SARS-CoV-2 a determined by binding antibodies to SARS-CoV-2 spike and nucleocapsid Presence of risk factors for symptomatic and asymptomatic infection with respiratory viruses Antibody and T cell kinetics of SARS-CoV-2 following infection Associations between the magnitude and quality of antibody and T cell responses to seasonal coronaviruses and protection from infection with SARS-CoV-2 Associations between infection with non-SARS-CoV-2 respiratory viruses and protection from infection with SARS-CoV-2 Associations between upregulation of gene expression in the mucosa, including interferon stimulated genes (ISGs), and protection from infection with SARS-CoV-2

The aim of this study is to find out the role of Covid-19 in salivary gland infection and its recurrence.

FUNCTION is an observational cohort study conducted by researchers from the Instituto de Medicina Tropical Alexander von Humboldt at Universidad Peruana Cayetano Heredia and Cayetano Heredia Hospital. The overall aim is to asses the long-term impact of SARS-CoV-2 infection on the cardiopulmonary function and quality of life in patients recovered from COVID-19, through a 6-month follow-up structured in 4 visits with clinical assessments and imaging studies performed by specialists.

Investigation of the correlation of CT-morphological changes of the lung compared to regional ventilation distribution on electrical impedance tomography in patients with post-acute-Covid-19 symptoms.

The purpose of this prospective, Phase 2, multicenter, blinded, randomized placebo controlled study is to demonstrate that early treatment with mavrilimumab prevents progression of respiratory failure in patients with severe COVID-19 pneumonia and clinical and biological features of hyper-inflammation.

Multicenter, randomized, placebo-controlled, parallel, blinded, interventional, treatment clinical trial with two arms. Population: 392 Patients with COVID-19 (Coronavirus Disease-19), confirmed by RT-PCR (Real Time polymerase chain reaction), symptomatic in the early phase of the disease. Experimental group: 196 patients, nitazoxanide 500mg 8 / 8 hours for 5 days. Control group: 196 patients, placebo 8/8 hours for 5 days.

In this study we propose to treat 560 patients with ramipril or placebo for 14 days. After an initial evaluation for COVID-19 status, medical history, and symptom assessment, patients will receive either 2.5 mg/day of ramipril or placebo. Patients' symptoms and study endpoints will be monitored at regular intervals. After 14 days, patients will undergo a laboratory assessment and an end-of-treatment follow-up visit at day 28. The primary endpoints of successful therapy will be improved survival, reductions in ICU admissions, and/or reductions in use of mechanical ventilator support.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for coronavirus disease 2019 (COVID-19), is associated with a high incidence of acute respiratory distress syndrome (ARDS) and death. Hypertension and cardiovascular disease are risk factors for death in COVID-19. Angiotensin converting enzyme 2 (ACE2), an important component of the renin-angiotensin system, serves as the binding site of SARS-CoV-2 and facilitates host cell entry in the lungs. In experimental models, angiotensin converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) have been shown to increase ACE2 expression in several organs, potentially promoting viral cell invasion, although these findings are not consistent across studies. Alternatively, ACEIs and ARBs may actually improve mechanisms of host defense or hyperinflammation, ultimately reducing organ injury. Finally, ACEIs and ARBs may have direct renal, pulmonary and cardiac protective benefits in the setting of COVID-19. Therefore, it is unclear if ACEIs and ARBs may be beneficial or harmful in patients with COVID-19. Given the high prevalence of hypertension, cardiovascular and renal disease in the world, the high prevalence of ACEIs or ARBs in these conditions, and the clinical equipoise regarding the continuation vs. discontinuation of ACEIs/ARBs in the setting of COVID, a randomized trial is urgently needed. The aim of this trial is to assess the clinical impact of continuation vs. discontinuation of ACE inhibitors and angiotensin receptor blockers on outcomes in patients hospitalized with COVID-19.

This study will compare two drugs (hydroxychloroquine and azithromycin) to see if hydroxychloroquine is better than azithromycin in treating hospitalized patients with suspected or confirmed COVID-19.

Convalescent plasma (CP) has been used in recent years as an empirical treatment strategy when there is no vaccine or treatment available for infectious diseases. In the latest viral epidemics, such as the Ebola outbreak in West Africa in 2014, the World Health Organization issued a document outlining a protocol for the use of whole blood or plasma collected from patients who have recovered from the Ebola virus disease by transfusion to empirically treat local infectious outbreaks
