Filter by:This protocol tests the safety and efficacy of a novel universal vaccine concept called "allo-priming" which is designed to protect elderly adults from progression of any type of viral infection, including possible protection against progression of the current outbreak of COVID-19 infection, and any future variants, strains, mutations of the causative SARS-CoV-2 virus as well as protection from any future currently unknown newly emergent novel viruses.
The aim of the project is to evaluate the immunological features of COVID-19 patients. Patients are recruited without any pharmacological treatments restriction. The number of samples is estimated on the basis of feasibility, that means on the maximum number of patients with COVID-19, who are expected to be able to be enrolled by the units involved. Based on the investigators' experience, gained in the onco-immunological field, considering the time and economic resources available, the investigators expect to enroll at least 80 patients.
This study evaluates a single use point of care diagnostic test in the diagnosis of influenza and other respiratory viral infections in adults. Participants will have a sample taken from their nose using a swab. The swab will be gently mixed in a liquid solution which will then be transferred into the device for testing.
Covid 19 is a pandemic infection developed in late 2019
Based on findings of the interim analysis of the ACTIVATE study showing 53% decrease of the incidence of all new infections with BCG vaccination, a new trial is designed aiming to validate if BCG can protect against COVID-19 (Corona Virus Disease-19).The aim of the study is to demonstrate in a double-blind, placebo-controlled approach if vaccination of participants susceptible to COVID-19 with BCG vaccine may modulate their disease susceptibility for COVID-19. This will be validated using both clinical and immunological criteria. At the same time, a sub-study will be conducted and the mechanism of benefit from BCG vaccination by assessing its effect on vascular endothelial function and mononuclear blood cells will be studied
This observational study will describe lung ultrasound (LUS) findings over time in hospitalized patients with moderate to severe Covid-19 lung disease. Our primary aim is to investigate if lung ultrasound can identify and/or predict patients requiring mechanical ventilation. Another aim is to describe LUS findings associated with clinical findings and patient condition.
In this pilot trial, 150 confirmed COVID-19 individuals will be randomly assigned to 1 of 5 groups: distilled water, CloSYS Ultra Sensitive Rinse (Rowpar Pharmaceutical Inc., USA), Oral-B Mouth Sore (Oral-B, USA), Crest Pro-Health Multi-Protection (Crest, USA), or Listerine Zero (Johnson and Johnson, USA). Study participants will be asked to rinse/gargle with 10-20ml (according to the rinse instructions) of the assigned solutions 4 times per day, for 30-60 seconds, for 4 weeks.
Ebola virus is one of the most dangerous human pathogens and is an emerging public health problem in sub-Saharan Africa. Ebola virus disease (EVD) first appeared in 1976. The current epidemic in the Democratic Republic of the Congo (DRC) is one of the largest and most complex ever recorded, and is not yet under control: a new death has been reported on April 10th, 2020. The epidemic was declared a public health emergency of international scope by the World Health Organization (WHO) on July 17th, 2019. Two studies are the "standard" in the assessment of the consequences of infection in survivors, in Liberia (PREVAIL) and Guinea (PostEbogui), especially in: - The observation of comparable mortality rates, even if over time there was an improvement in survival, probably linked to the improvement in the quality of care and symptomatic treatment; - And the study of the contacts of the survivors, between 4 to 10% of them had done seroconversion with regard to Ebola virus (EBOV) in an asymptomatic or pauci-symptomatic way and that this rate varied according to the degree of exposure to the risk. The DRC's experience in this area and the enormous progress made in the fight against Viral hemorrhagic fevers (VHFs), therapeutically and preventively (where much of which patients have benefited from antiviral treatment or monoclonal antibodies), the technological responses (real-time sequencing of Ebola strains in new cases, vaccination or the use of individual isolation units), show the limits of their effectiveness. A large number of questions therefore remain unanswered: - The antibody profile of the survivors, in particular the repertoire of immunoglobulin G (IgG) specific to these individuals and its correlation with survival and its evolution over time; - The impact of treatments initiated during the acute phase on these immune abnormalities; - Finally, genetic factors linked to the host could play an important role in the response to the Ebola virus. The aim of this study is to provide a better overall understanding of Ebola virus infection and its clinical, virological, and immunological consequences, of cured people and their contacts; strengthen multidisciplinary monitoring of patients after an acute phase of EVD. The results will therefore have a direct impact on the clinical management of this population and on the prevention of possible secondary contamination in the Democratic Republic of the Congo.
This randomized clinical trial will evaluate the benefit of platelet-rich plasma (PrP) in the treatment of olfactory dysfunction. PrP can be isolated from a patient's own blood and has been found in previous studies to have anti-inflammatory and pro-regenerative properties. It has been used across multiple specialties, such as Orthopedics, Facial Plastics, Dermatology, Neurology in injected form to treat a wide variety of tissues to encourage the body's inherent regenerative capacity. The investigators have completed a pilot study here evaluating it's use in olfactory loss which demonstrated safety and also suggested efficacy. Therefore, the investigators aim to assess the ability of PrP to improve olfactory function in patients with decreased sense of smell.
The purpose of this research study is to learn more about the use of viral specific T-lymphocytes (VSTs) when given in the presence of COVID-19 signs and symptoms, caused by the virus SARS-CoV-2. VSTs are cells specially designed to fight viral infections. These cells are created from a blood sample collected from a donor who has recovered from COVID-19 infection. VSTs are investigational meaning that they are not approved by the Food and Drug Administration (FDA). COVID-19 is a new virus and treatment options are evolving rapidly. VSTs have been successfully used to treat many different viral infections and may be beneficial in treating COVID-19 in the absence of other treatments.
