Active clinical trials for "COVID-19"

A multi-centered clinical follow-up study to investigate the long-term dynamic of COVID-19 antibody level after vaccination.

THIS IS A PROSPECTIVE OBSERVATIONAL STUDY TO DETERMINE THE ROLE OF PHYSICIAN GESTALT IN CLINICAL PREDICTION OF COVID 19.

This study aims to assess the clinical presentation, radiological patterns and outcome of COVID-19 infection in patients with chronic pulmonary disease. Inter-relationship between the severity of COVID-19 infection and chronic pulmonary diseases.

Vaccines against the coronavirus type 2 causing severe acute respiratory syndrome Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) have been created in a short period of time due to the rapid spread of the virus. These vaccines use different and sometimes innovative technologies, such as the use of ribonucleic acid (RNA), or a non-replicating viral vector. Efficacy ranging from 70-90% in the first weeks after the second injection of these vaccines has been reported, with side effects whose causality remains to be determined.

At the beginning of 2020, coronavirus disease 19 (COVID-19) was declared a pandemic of international concern and an unprecedented challenge for country-specific health care systems . Patients infected with COVID-19 develop from mild, self-limiting respiratory tract illness to severe progressive pneumonia associated with multi-organ failure . In particular, COVID-19 has been shown to exert significant effects on the hematopoietic system and hemostasis

Healthcare workers (HCWs) play a vital role in determining the success of vaccination programs. Patient acceptance and vaccination rely greatly on the utilization and attitude of HCWs towards the vaccine, their attitude also influences patients' adherence to vaccination schedules and their hesitancy. HCWs themselves can be hesitant about a certain vaccine and thus can transfer their negative attitudes to their patients, increasing vaccine hesitancy among the general population. Frontline HCWs are at an increased risk of exposure to COVID-19 due to their direct contact with their patients, working hours, psychological stress and job burnout, they also face stigma. Dental health professionals in particular are at an increased risk due to their occupational hazards that include continuous exposure to body fluids and aerosols, this increases their risk of contracting COVID-19. Therefore vaccinating healthcare workers will be beneficial, not only for themselves, but also for their households and patients.

There is evidence that up to 30% of COVID-19 patients was reported with neurological manifestations such as impaired consciousness, headache, and dizziness have been reported in COVID-19 patients in addition, olfactory and taste alterations are common symptoms in patients affected by COVID-19.This study will be conducted to evaluate the effect of the novel coronavirus on audio-vestibular functions in confirmed COVID19 patients.

The COVID-19 pandemic is a major concern for people on long-term treatments that modify the immune system function. People with multiple sclerosis (pwMS) form a large group who receive such treatments called disease modifying therapies (DMTs). Several types of DMTs with different effects on the immune system are being used for multiple sclerosis (MS). In the absence of large-scale national studies, the risk of COVID-19 among pwMS on various DMTs has not been established. A few physician-reported registry-based studies have suggested that anti-CD20 monoclonal antibodies, such as ocrelizumab and rituximab, used in the treatment of MS can increase the risk of COVID-19. However, in our community-based COVID-19 study of a large cohort of pwMS as part of the UK MS Register, we could not demonstrate an association between DMTs and susceptibility to COVID-19. Other studies have not found any relationship between DMTs and the outcome of COVID-19 among pwMS. To our knowledge, UK is the only country in the world that collects national data on DMT use, providing us with the opportunity to investigate the impact of DMTs on COVID-19 susceptibility and severity in a large population of pwMS. In England, no DMT is being dispensed without prior approval and specialised commissioning by the national Health Services (NHS) England & NHS Improvement (NHSE/I). The scheme, currently implemented in over 100 NHS Trusts in England, ensures that treatment decisions are made in line with agreed commissioning policy and are evidence-based. NHSE/I also has access to Public Health England (PHE) held data on all people who have had a SARS-CoV-2 test. By identifying all pwMS on DMTs and all those who have had a test for coronavirus and collecting data on the clinical outcome of their COVID-19 from their local NHS hospitals, we would be able to establish the risk of COVID-19 and the risk of contracting the infection associated with different DMTs. The findings of the study will help MS clinical teams address the concerns of pwMS about taking DMTs during the COVID-19 pandemic and update their guidelines on the measures pwMS need to take during these unprecedented times.

Study Population Population with vaccinated with three different Covid Vaccines (Inactive Vaccine (Sinovac Life Sciences, Beijing, China), recombinant human adenovirus serotype number 26 (rAd26 of Sputnik V), mRNA Vaccine (Pfizer/BionTEC). This is multi center study, 5 centers will be joined to study from different part of the country. Approximately 1500 people will be enrolled to study.

The primary goal of the VIRIONUM project is to analyze the association of clinical, socio-demographic characteristics of patients and their genetic polymorphism, inflammatory and other biochemical markers with disease progression and death in subjects with COVID-19 disease. The research is an observational, cohort study with nested-case control design, including adult, male and female COVID-19 inpatients. Primary dependent variable will be outcome of disease, defined as discharge from the hospital or death. The outcomes and putative risk factors will be analyzed using binary logistic regressions. The proposed multi- and inter-disciplinary study should provide additional scientific evidence about risk factors for the development of severe forms of the disease and the COVID-19-related death.
