Active clinical trials for "COVID-19"

Serum antibody titre against COVID-19 spike protein will be measured before, after the first dose, and after the second dose (when applicable) in cancer patients who are receiving or received anti-cancer drugs. Side effects of vaccination and actual incidence of COVID-19 will be monitored.

Vaccine hesitancy is defined by the WHO's Strategic Advisory Group of Experts on Immunization as a 'delay in acceptance or refusal of vaccination despite availability of vaccination services'. This varies in form and intensity based on when and where it occurs and what vaccine is involved. Several prophylactic vaccines against COVID-19 are currently available. As the world is beginning the roll-out the first approved vaccines, little is known about people's potential acceptance of a COVID-19 vaccine in most of the African countries. ACHES (African COVID -19Vaccine Hesitancy) is an observational study aimed at measuring COVID-19 vaccine hesitancy in five west African countries and exploring causes behind the hesitancy with the main objective of informing guidelines for the proficient roll-out of the vaccines in the region.

The epidemic caused by the new coronavirus appeared in December 2019 and spread rapidly, and it has had a serious impact on the social development and people's lives in the world. On February 11, 2020, the World Health Organization (WHO) named the infectious disease caused by the virus COVID-19. my country classifies it as a Class B infectious disease, and controls it as a Class A infectious disease. In order to effectively respond to the epidemic, on January 23, 2020, Zhejiang Province first launched a first-level response to major public health emergencies across the country. Some patients with new coronary pneumonia, especially critically ill patients, may go to the emergency department first. Emergency medical staff must identify and isolate patients with new coronary pneumonia in a timely manner while ensuring the treatment of critically ill patients. People face greater unknowns and challenges in the anti-epidemic work. this research Participating in the prevention and control of the new crown pneumonia epidemic through investigations in the emergency department of Zhejiang Province Related conditions, to further improve the hospital's emergency medical service capabilities for reference.

Performance of diagnostic or therapeutic endoscopic procedures in inflammatory bowel disease (IBD) patients can be challenging during a viral pandemic; the main concerns being the safety and protection of patients and health care providers (HCP). The aim of this study is to identify endoscopic practice patterns and outcomes of IBD and coronavirus disease 19 (COVID-19) with a worldwide survey of HCP.

Limited large-scale studies have been conducted to investigate the adverse effects of COVID-19 vaccine in Latin America, particularly among the healthcare worker (HCW) population in Ecuador. The objective of this study was to assess a cohort of Ecuadorian healthcare workers for adverse reactions following vaccination with the Pfizer-BioNTech vaccine.

Social isolation rules applied to prevent and control COVID-19 disease reduce cross-infection, exposure to more allergens in the home environment, reducing hospital admissions by avoiding contamination, asthma control, fear of COVID-19 and physical activity for reasons such as increased anxiety and lack of exercise. How it will affect is unclear. Considering all these, positive or negative changes in asthma-related risk factors, changes in physical activity level, asthma attacks and control, fear of COVID-19 will be examined and contribute to the literature in children with asthma.

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.

Ophthalmologic damages secondary to COVID-19 coronavirus infection are little described. The ocular involvement is probably multiple, ranging from pathologies of the anterior segment such as conjunctivitis and anterior uveitis to disorders that threaten vision such as retinitis or optic neuropathy. On the other hand, in addition to this impairment, when patients are hospitalized for acute respiratory failure, complications related to possible resuscitation, medication prescriptions, positioning and oxygenation. COVID-19 itself, has several components: An apoptotic action of the viral attack which will generate cellular destruction, whether pulmonary, cardiac or renal or maybe ocular A secondary autoimmune action with the development of major vascular inflammation, possibly reaching the retinal, choroidal, and optic nerve vessels. A secondary "hyper" inflammatory syndrome with flashing hypercytokinemia and multi-organ decompensation is described in 3,7% to 4 ,3% of severe cases. A thromboembolic action

Mechanically ventilated patients with coronavirus disease 2019 (COVID-19) have a mortality of 24-53%, in part due to distal mucopurulent secretions interfering with ventilation. Dornase alfa is recombinant human DNase 1 and digests DNA in mucoid sputum. Nebulized dornase alfa is FDA-approved for cystic fibrosis treatment. DNA from neutrophil extracellular traps (NETs) contributes to the viscosity of mucopurulent secretions. NETs are found in the serum of patients with severe COVID-19, and targeting NETs reduces mortality in animal models of acute respiratory distress syndrome (ARDS). Thus, dornase alfa may be beneficial to patients with severe COVID-19-acting as a mucolytic and targeting NETs.

Given the current situation with COVID-19 declared pandemic on March 11, 2020 and the requirement for physical distancing and to limit social interactions, and for some, to quarantine, the investigators will survey patients living with type 1 diabetes (and their families, if they are <18 years) about their current experience with their diabetes management to understand their needs. The primary objective is to describe the exposition and the impact of COVID-19 pandemic on type 1 diabetes. The investigators will recruit people with type 1 diabetes from all ages living in Quebec to answer a short online survey.
