Filter by:In the present context, it seems necessary to try to describe as precisely as possible the physiological alterations due to COVID-19. From these observations, therapeutic proposals adapted to this new disease may then be developed, particularly in the symptomatic management of the critically ill patient. It therefore seems essential to rigorously study these modifications, as they have been studied in the past for ARDS. The aim of this non-interventional study is to describe precisely the respiratory and hemodynamic changes induced by COVID-19 in mechanically ventilated patients .
The purpose of this clinical trial is to assess the safety and efficacy of Clevudine 120 mg versus placebo once daily administration with standard of care therapy for 14 days (maximum up to 21 days) in patients with moderate COVID-19.
Healthcare workers (HCW) at risk of Covid-19 will have baseline serology for SARS-CoV-2 to see if they are already immune to Covid-19. HCW will get baseline assessment and if meeting inclusion criteria and no exclusion criteria they will be randomized in a 2:1 ratio to hydroxychloroquine or Vitamin C on a weekly basis for three months. Subjects will complete daily diary of symptoms and temperature, and will have repeat SARS-CoV-2 serology at 6 weeks and 3 months to determine seroconversion.
There is no evidence that the Bacille Calmette-Guérin vaccine (BCG) protects people against infection with COVID-19 virus. Two clinical trials addressing this question are underway, and WHO will evaluate the evidence when it is available. In the absence of evidence, WHO does not recommend BCG vaccination for the prevention of COVID-19. WHO continues to recommend neonatal BCG vaccination in countries or settings with a high incidence of tuberculosis. There is experimental evidence from both animal and human studies that the BCG vaccine has non-specific effects on the immune system. These effects have not been well characterized and their clinical relevance is unknown
SARV-CoV-2 infection was considered pandemic on March 11, 2020. The SARV-CoV-2 epidemic affected France from the beginning of March, spreading in particular from a 4-day large evangelical meeting of 2500 people on February 17 in the city of Mulhouse (North East of France). The Montpellier University Hospital has set up a clinical pathway for people suspected of being infected with SARV-CoV-2 because of signs compatible with pneumonia (screening criteria in France during the study period). This includes an emergency department, an infectious disease department dedicated to the surveillance of infected people requiring hospital treatment, and an intensive care unit for the most severe cases. The diagnosis of infection with SARV-CoV-2 was confirmed in approximately 20% of people initially referred in this special care system. The main objective of this cohorte is the collection of clinical data and biological samples from care for non-interventional research on the patients with a possible or confirmed SARS-CoV -2 infection, from diagnosis to long-term follow-up.
This non-interventional, observational study retrospectively (and in parts prospectively) investigates, if a Covid-19 associated Nephritis, diagnosed by Urine-dipstick and further Urine-analyses on addmission, can help to predict later complications, adverse outcomes and later need for ICU-capacity in Covid-19 patients as well as can guide preventive strategies.
This study aims to evaluate the experience of Alberta patients with inflammatory arthritis who participate in the the RAPPORT-ONTRAAC registry during the COVID-19 pandemic, specifically comparing the experience of those taking anti-malarial medications compared to those who do not. This registry includes approximately 2500 northern Alberta patients with inflammatory arthritis who receive highly complex therapies which may be associated with side effects. This program of data collection and research has been evaluating the effectiveness and safety as well as associated health care costs of rheumatoid and psoriatic arthritis patients since 2004. The principle investigators are based at the University of Alberta while the co-investigators are academic rheumatologists at the University of Alberta. The registry has approximately 900 patients taking anti-malarials combined with their complex therapies and ~ 1500 not on anti-malarials in combination with their complex therapies. We aim to perform a case control study evaluating the impact of anti-malarial drugs (eg. hydroxychloroquine and chloroquine) on the development of COVID-19 compared to those patients who are not on anti-malarial drugs over the next 6-12 months. In addition to frequent e-mail surveys screening for the clinical symptoms of COVID-19 and understanding their concomitant arthritis medication use, we will compare the healthcare outcomes of both groups of arthritis patients with and without COVID-19 for the duration of the pandemic. This information will provide critical information beyond an anecdotal level on whether or not anti-malarials truly provide a protective benefit against COVID-19 or reduce the severity of infection. A blood sample from all participants (Covid-19 positive and negative) will be drawn approximately six months into the study for measurement of antibodies to Covid-19 and possible blood types and HLA alleles. Additionally, this study will be linked to another study "Persistence of SARS-Cov2 in immunocompromised patients" which will specifically evaluate COVID-19 serology and nasopharyngeal swab findings in the subset of patients who develop COVID-19.
Coronavirus disease (COVID-19) pandemic has started to affect Saudi Arabia and is expected to cause a lot of morbidities and many patients, especially the elderly, will require intensive care unit (ICU) support to survive as its lethality increases with the increasing age. Development of a vaccine by pharmaceutical companies like Roche and antibody concentrates from convalescent patients' plasma by Takeda will take 10-12 months to complete, and we speculate that it will be overwhelmingly expensive and limited in supply. We are presenting this urgent proposal to use the convalescent plasma to save the lives of severely affected COVID-19 patients. Most of the logistic support is already available in MOH Saudi Arabia, and it will be a cheap and quick technique based on the time-tested principles of passive immunization which is supported by the most recent data from China. We are proposing to test the therapeutic potential of convalescent plasma (from patients who have fully recovered from COVID-19) in treating patients with serious COVID-19 disease or those who are at risk of developing a serious disease based on their comorbidities profile. Convalescent plasma could provide our first-line defense for people with Covid-19, especially those who are older and at a much higher risk for complications. Amid the COVID-19 pandemic, with no available vaccine or proven antiviral drug, antibodies from recovering patients could provide a "stopgap" measure to help in controlling the pandemic effects on health and economy. We plan to recruit at least 40 consenting donors and patients. Non-consenting patients will serve as controls.
Nasal saline irrigations are a safe and commonly used mechanism to treat a variety of sinonasal diseases including sinusitis, rhinitis, and upper respiratory tract infections. When used properly, these irrigations are a safe and easy intervention available over the counter without a prescription. Additionally, baby shampoo has been found to be a safe additive functioning as a surfactant when a small amount is added to the saline rinses which may help augment clearance of the sinonasal cavity. While many systemic medications and treatments have been proposed for COVID-19, there has not yet been a study looking at targeted local intervention to the nasal cavity and nasopharynx where the viral load is the highest. Studies have shown that the use of simple over the counter nasal saline irrigations can decrease viral shedding in the setting of viral URIs, including the common coronavirus (not SARS-CoV-2). Further, as SARS-CoV-2 is an enveloped virus, mild-detergent application with nasal saline would neutralize the virus further. It is our hypothesis that nasal saline or nasal saline with baby shampoo irrigations may decrease viral shedding/viral load and viral transmission, secondary bacterial load, nasopharyngeal inflammation in patients infected with the novel SARS-CoV-2.
Since end of December, a new coronavirus, close to the 2002 SARS coronavirus, cause serious pneumonias throughout world. There is currently no strong evidence of an efficient specific treatment. Hydroxychloroquine is an old chloroquine-derived drug, prescribed for auto-immune disorders. It has shown efficacy against Sars-CoV-2 in vitro. Some studies showed that Hydroxychloroquine might improve the clinical status of Sars-CoV-2 infected patients. Azithromycin is a macrolide antibiotic, with immunomodulatory properties. Adding Azithromycin to a hydroxychloroquine-based treatment showed an apparent accelerated viral clearance in infected patients. This study wants to evaluate the clinical impact of adding Azithromycin to Hydroxychloroquine in the treatment of Sars-CoV-2 pneumonia
