Active clinical trials for "COVID-19"

COVID-19 is respiratory disease caused by the severe acute respiratory coronavirus 2 (SARS-CoV-2), a novel coronavirus which has spread rapidly across the world with over 149.9 million laboratory confirmed cases and over 3.1 million reported deaths since December 2019. Approximately 4-8% of hospitalized patients with COVID-19 have co-infection with bacterial pathogens however there is widespread and often broad-spectrum antibiotic use in these patients. This is a prospective, multi-center, non-inferiority pragmatic clinical trial of antimicrobial stewardship prospective audit and feedback versus no antimicrobial stewardship intervention on physicians attending to patients with proven SARS-CoV-2 infection confirmed by nucleic acid testing in the preceding 2 weeks of hospitalization for acute COVID-19 pneumonia. Prospective audit and feedback is the real time review of antibacterial prescriptions and immediate feedback to prescribers to optimize antimicrobial prescriptions. Hospital beds will be stratified by COVID unit and critical care unit beds, and will be computer randomized in a 1:1 fashion into 2 arms (antimicrobial stewardship intervention versus no antimicrobial stewardship intervention) prior to study commencement at the participating site. Patients hospitalized to study-eligible beds will be followed for primary and secondary outcomes. The objective of this study is to determine the effect of an antimicrobial stewardship intervention (prospective audit and feedback) on clinical outcomes in patients hospitalized with acute COVID-19.

The Coronavirus Disease 2019 (COVID-19), caused by the SARS-CoV-2 virus, is a worldwide pandemic that has resulted in large-scale quarantines in cities, states, and countries throughout the world. SARS-CoV-2 is a respiratory virus that is most commonly spread via contact with infective respiratory droplets and aerosols produced by coughing, sneezing, talking, and singing. Children with medical complexity (CMC), i.e., children with multiple severe chronic conditions, high resource use, severe functional limitations, and substantial family-identified service needs, are a medically vulnerable population for the development of severe COVID-19. Deciding to send CMC to school poses a major dilemma to families wanting to minimize severe COVID-19 risk. School personnel also face risks when CMC attend school. Despite these challenges, achieving in-person school attendance is critical for CMC. Compared to non-CMC, academic and social development for most CMC hinges on being at school. Severe intellectual and developmental disability impairs one's ability to engage with online platforms. Health-promoting services delivered at school, e.g., physical, occupational, and speech therapy, are likely less effective when delivered virtually. Parents of CMC, already disproportionately unemployed due to their child's care needs, experience added employment strain when their child is out of school. The study objective is to increase the safe return to school for CMC by 1) evaluating the feasibility of school-based COVID-19 testing strategies and 2) identifying parent and staff perceptions of testing and school attendance. A related study (ReSET Aim 1a, NCT04895085) will evaluate the same factors in home-based testing strategies in CMC exclusively.

Coronavirus COVID-19 is an emerging virus also called Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Eighty percent of patients are poor or asymptomatic. However, there are major respiratory complications for some patients, requiring intensive care hospitalization and possibly leading to death in 5% of cases. One of the hypotheses put forward is that much of the pathophysiology is due to endothelial dysfunction associated with disseminated intravascular coagulation. The covid-19 pathology could induce coagulation impairment as observed during sepsis. An increase in D-dimer levels during covid-19 disease is itself associated with excess mortality. While D-dimers are highly sensitive, they are not specific for clotting activity. They may be increased in many other circumstances, particularly in inflammation. On the other hand, the infection stimulates the release of extracellular vesicles. These vesicles, of multiple cellular origin, are an actor of vascular homeostasis, and participate in the state of hyperactivation of coagulation. They have a major role in the prothrombotic state and the development of coagulopathy associated with sepsis. The aim of our monocentric prospective study would be to study early and more specific markers of hypercoagulability and markers of routine endothelial dysfunction, as soon as the patient is hospitalized, in order to predict the risk of hospitalization in intensive care.

Severe acute respiratory syndrome (SARS) SARS-Cov-2 disease (COVID-19) is an infectious disease caused by a coronavirus. The pandemic first described in Wuhan, China, has since spread across the whole world and caused dramatic strain on health care in many countries. Patients infected with the virus mostly report mild to moderate respiratory symptoms like shortness of breath and coughing, and febrile symptoms. It is of paramount importance to preserve health service capacity by identifying those with serious illness without transferring all infected patients to emergency rooms or Hospitals. In addition, it is important to identify seriously ill patients early enough and before they reach a point of deterioration where they can be extremely challenging to handle in both prehospital and hospital environment. The present study is designed to sample biosensor data from patients treated and observed at home due to mild and moderate SARS-Cov-2 disease. Such a system would be useful, both for the treatment of individual patients as well as for assessing the efficacy and safety of care given to these patients. Investigators intend to improve quality and safety of home care by continuous monitoring and a set of rules for follow-up. Investigators hypothesized that patients and local health system may benefit from the feedback of a simple monitoring system, which detects changes in respiration, temperature and circulation variables in combination with the patient's subjective experiences of care. Patients may be referred to hospitalization earlier. In the present study we will use live continuous and non-continuous biosensor data to monitor the development of vital parameters for Covid 19 patients compared with patients who are not monitored electronically (standard of care).

This is a Phase 1 Randomized, Double-Blind, Parallel Group, Placebo-Controlled Study to Assess the Safety of Ascending Doses of UNI911 INHALATION in Healthy Volunteers in Preparation for Evaluation in Adults with COVID-19

The purpose of this study is to document the feasibility and tolerability of low dose thoracic radiotherapy in patients with WHO level 5 COVID 19 infections.

The COVID-19 pandemic is considered as the most crucial global health concern of the century. Given the complex interaction of physical and social factors on fast spreading infection, there have been increasing calls for comprehensive efforts using a community-based participatory research (CBPR) approach. CBPR partnership composed of representatives from community-based organisations, health and academia actively developed the present study. Specific aims were (1) to assess the efficacy and safety of Ayurvedic combination, Giloy (Tinospora Cordifolia) and Pippali (Piper longum) in the management of mild-to-moderate cases of COVID-19 and (2) to determine the effect in relieving COVID-19 symptoms and preventing the onset of severe infection.

Based on the literature, it seems likely that a nutritional intervention with nicotinamide (a form of vitamin B3) can support the therapy of SARS-CoV-2 infection (COVID-19). A pilot phase of the COVit trial showed an effect of nicotinamide on the time to complete resolution of COVID-19 symptoms. In addition, diarrhoea is a common symptom of COVID-19. Therefore, in a second part of the study, 420 symptomatic patients each with confirmed SARS-CoV-2 infection are to take 1,000 mg nicotinamide (500 mg conventional nicotinamide and 500 mg nicotinamide released in a controlled manner in the intestine) or corresponding placebos per day in a blinded fashion for 4 weeks. The primary endpoint of the trial is the occurrence of individual COVID-19 symptoms over time (primary analysis time point: week 2). Secondary endpoints focus on the severity of COVID-19 symptoms, the post-COVID-19 syndrome (PCS), anti-SARS-CoV-2 antibody levels, and the time to resolution of individual or all symptoms. Exploratory endpoints include the WHO clinical scale for COVID-19, development of severe COVID-19, fatigue, quality of life and biomarkers. Patients are approached after positive testing and give their informed consent online. After randomised distribution of the trial supplements, patients are interviewed by telephone about their disease course at baseline (week 0), week 2, week 4, week 6 and after 6 months. Stool samples are collected from up to 400 patients at the same timepoints. In addition to blood count and standard blood profile, various inflammatory markers and the metabolome, in particular tryptophan metabolism, are examined in the blood of up to 20 selected patients. In these patients, the viral strain is determined by sequencing from nasopharyngeal swabs. In selected patients, short-term pharmacokinetics of nicotinamide, nicotinic acid and nicotinuric acid as well as of metabolites of nicotinamide and tryptophan are investigated. In the stool, changes in the microbiome (in 100-300 patients) as well as metagenome and metabolome (in a subgroup) will be analysed. The study is expected to produce rapid results on whether nicotinamide supplementation can alleviate the disease course of COVID-19. Moreover, a follow-up interview, a smell test, a cognitive test and anti-SARS-CoV-2 antibody levels after at least 6 months will be used to investigate whether the supplementation has any influence on PCS as well as the immune reaction against SARS-CoV-2.

Uptake of vaccination against COVID-19 is key to controlling the pandemic. However, a significant proportion of people report that they do not intend to have a vaccine, often because of concerns they have about its side effects or safety. It is important to identify ways to communicate information about the vaccines that facilitate informed decisions rather than promoting uptake through coercion. This study will assess whether theory-based messages can change beliefs and increase intentions to receive a COVID-19 vaccine in Scotland. The messages will be based on publicly available information about the need for COVID-19 vaccination and the safety of the vaccines, and structured to address specific types of treatment beliefs. Participants will be randomised to either a group shown the messages or a control group shown general information messages about the COVID-19 virus and vaccination programme. By comparing the two groups we aim to test what impact the theory-based messages have on intentions and beliefs about COVID-19 vaccination.

The immunomodulatory effects of vitamin D are known to be beneficial in viral infections, it is also known that its deficiency is associated with a worse prognosis of COVID-19. This study aimed to determine the baseline vitamin D serum concentrations in asymptomatic or mildly symptomatic COVID-19 outpatients, as well as to evaluate the effects of supplementation with 10,00 IU/daily of vitamin D3 and its relationship with biochemical parameters and clinical features.
