Filter by:The rapid spread of COVID-19 is expected to have a significant impact on medicine as well as all sectors worldwide. In particular, inflammatory bowel disease (IBD) is a chronic immune disease in which remission and activation are repeated and must be treated consistently throughout life. In addition, patients with IBD may be vulnerable to various infectious diseases due to the immuno-compromised state due to the use of immuno-suppressants or biological agents. During a pandemic, patients with IBD may postpone hospital visits due to concerns about infection with COVID-19, and if they cannot continue drug treatment, there is a concern about the flare up IBD disease activity. Therefore, in this study, we would like to investigate the current status of hospital utilization of IBD patients in Daegu, the epidemic area of COVID-19, and to investigate the effect of patient perception of COVID-19 on hospital ultilization.
The goal of this clinical trial is to investigate the therapeutic efficacy of rapidly correcting vitamin D deficiency in adults with the use of 25-hydroxyvitamin D3 [25(OH)D3] for reducing the risk of acquiring the SARS-CoV-2 (COVID-19) viral infection and mitigating morbidity and mortality associated with this infection. This evidence-based hypothesis is related to several observations. Macrophages, activated T and B lymphocytes have a vitamin D receptor and 1,25-dihydroxyvitamin D3 induces defensin protein synthesis, influences immunoglobulin production and modulates T-cell cytokine production and functions. 1,25-dihydroxyvitamin D3 also reduces the angiotensin-converting enzyme 2 (ACE2) that is believed to serve as the binding site and gateway for COVID-19 to become infectious. This is a multicenter randomized3 doubleblinded placebo-controlled study aimed at determining the benefits of 25(OH)D3 treatment for the prevention of COVID-19 infection and improving clinical outcomes in infected patients. The investigators plan to recruit 1500 subjects in 3 study groups that include hospital health providers, patients with a positive test for COVID-19 and their relatives with a negative test. Eligible subjects in each study group with a documented serum level of 25(OH)D < 20 ng/mL will be randomized. Recruited subjects will be given 25 mcg of 25(OH)D3 daily or an identically appearing placebo at the time of randomization for two months. Three hospitals will participate and the sample size is foreseen to be equally distributed between the three. Since the clinical trial is designed as minimal risk a formal committee for data monitoring is not foreseen. However, potential toxicity will be monitored every 4 weeks with a serum calcium, albumin and creatinine by the PI and the study coordinators. If the corrected serum calcium increases above 10.6 mg/dl and a repeat confirms that the calcium is above 10.6 mg/dL the subject will be dropped from the study and referred to his or her PCP. Early signs and symptoms of vitamin D toxicity associated with hypercalcemia are increased thirst, increase in frequency of urination, especially at night. The subjects will be followed up weekly by phone to ask about their sign and symptoms.
There is an evidence gap in relation to the incidence, impact and severity of COVID-19 in newborn babies. International data are very limited, we have no robust estimates of incidence and no UK-based data with which to inform policy, clinical care, service delivery or advice to pregnant women. The research aims are to investigate the three mains ways in which COVID-19 might affect newborns and babies that need neonatal care: 1. Newborn babies might catch COVID-19 before, during or soon after birth and this may lead to problems with breathing or feeding that need support in hospital. 2. COVID-19 could affect babies that are already on neonatal units with other medical conditions (like being very premature) that place them at greater risk of severe COVID-19. 3. COVID-19 might affect that way that pregnant women are looked after in pregnancy, labour or bith which could lead to problems for some babies, even if they do not themselves become infected with COVID-19.
This study compares two intubation boxes, that is the Taiwan "Aerosol Box" versus the UMMC "Intubation Box". The importance of this intubation box has come to light recently in view of the COVID-19 pandemic and the fact that intubation is an aerosol-generating procedure. Risks of the healthcare worker attending to the airway of COVID-19 patients is high and the intubation box aims to minimize that and reduce contamination of the environment. The original design of the "Aerosol Box" has limitations and is not easily used by intubators. This study evaluates the clinical usefulness of an innovation of the "Aerosol Box" design that is made to be more ergonomic and increases the rate of successful intubation. Anaesthetists with more than 5 years of clinical experience in intubating airways as well as more than 20 successful intubations using videolaryngoscopy , will be available to participate. This study will employ manikin and will be a randomized cross-over trial, conducted in UM.
An increased risk of both venous and arterial thromboembolism was noted in reports from SARS-CoV-2-infected patients in China and has been confirmed in autopsy findings from patients who experienced sudden death. Myeloproliferative Neoplasms (MPNs), which encompass polycythemia vera, essential thrombocythemia and primary myelofibrosis, are thrombophilic disorders with a natural propensity to thrombosis that is fuelled by the intrinsic activation of inflammatory cytokines. It therefore follows that an underlying diagnosis of MPN may increase the risk of worse clinical outcomes and death during periods of active Covid-19 disease. This ambispective, observational study aims to elucidate the key factors which affect the clinical course of patients with MPN who develop Covid-19 disease.
Based on emerging experience and trials from countries affected early by the COVID-19 (COV19) pandemic, there is evidence that a subgroup of severely affected people develop a hyperinflammatory (HI) syndrome (COV-HI). Trials are in progress of cytokine inhibition and other immune modulation to treat COV-HI. This proposal aims to use a rapidly executed cohort study to characterise the clinical phenotypes of COV-HI in patients in the UK through an established and nimble network of clinicians and scientists with broad experience of identifying and treating HI. The aim is to confirm the COV-HI clinical phenotype and using routine data to try to infer the inflexion point where COV-HI emerges. This would enable refinement of the proposed treatment algorithm and translates to routine clinical practice to improve the outlook for COV-HI.
Passive immunotherapy through plasma infusion of convalescent subjects - convalescent plasma - or "hyperimmune" plasma was one of the most widespread and effective anti-infective treatments in the pre-antibiotic era and one of the founding pillars of immunology, and has also been used during the SARS (2002-2003) and Ebola (2014-2016) viral epidemy for which there were no alternative immunoprophylactic or therapeutic interventions. To date, there are not proven etiological therapies for SARS-CoV-2 infection, the agent responsible for the disease called Covid-19. Among those subjected to clinical studies during the current epidemic in China, hyperimmune plasma appears to be one of the most rational and promising. The objective of this study will be to evaluate the efficacy and safety of the hyperimmune plasma administered add-on to the anti-Covid-19 treatment (standard therapy) according to clinical practice in patients with severe Covid-19 infection, compared to patients with severe Covid-19 infection treated only with standard therapy.
CovidSurg-Cancer is an international, multicentre, observational cohort study designed to evaluate the 30-day COVID-19 infection rates in elective cancer surgery during the COVID-19 pandemic. Centres can elect to include one or more cancer types in the study, in any combination, depending on local expertise and capacity. During the pilot study, investigators should enrol patients with confirmed diagnoses of: - Colorectal cancer - Oesophagogastric cancer As a rapid response study to the COVID-19 pandemic, included cancer types will evolve throughout the course of the CovidSurg-Cancer study period, for example, to include breast, liver, pancreatic, gynaecological, urological cancers, or sarcomas.
Surfactant replacement therapy (SRT) improves oxygenation and survival in NRDS and some infant ARDS. SRT was tried in adult ARDS with conflicting results. Research by Filoche and Grotberg helped to understand the failure of previous clinical trials and yielded a strong scientific rationale for SRT success, now allowing to design a new administration protocol for SRT in adults, to be tested by this clinical trial in COVID-19 adult ARDS patients. Patients will be randomized to receive either a bronchial fibroscopy alone (with aspiration of secretions) or a bronchial fibroscopy with administration of 3 mL/kg of a solution of poractant alpha diluted to 16 mg/mL and distributed into each of the 5 lobar bronchi.
COVID-19 infection has spread worldwide causing several deaths in few months Convalescent Plasma from COVID 19 donors has shown huge activity in small series from Chinese patients and currently many centers from USA and the European Union are assessing its use looking to avoid mortality and prolonged hospitalizations COVID-19-related
