Filter by:This is a prospective, multi-site study designed to evaluate whether the use of hydroxychloroquine in healthcare workers (HCW), Nursing Home Workers (NHW), first responders (FR), and Detroit Department of Transportation bus drivers (DDOT) in SE, Michigan, can prevent the acquisition, symptoms and clinical COVID-19 infection The primary objective of this study is to determine whether the use of daily or weekly oral hydroxychloroquine (HCQ) therapy will prevent SARS-CoV-2 infection and COVID-19 viremia and clinical COVID-19 infection healthcare workers (HCW) and first responders (FR) (EMS, Fire, Police, bus drivers) in Southeast Michigan. Preventing COVID-19 transmission to HCW, FR, and Detroit Department of Transportation (DDOT) bus drivers is a critical step in preserving the health care and first responder force, the prevention of COVID-19 transmission in health care facilities, with the potential to preserve thousands of lives in addition to sustaining health care systems and civil services both nationally and globally. If efficacious, further studies on the use of hydroxychloroquine to prevent COVID-19 in the general population could be undertaken, with a potential impact on hundreds of thousands of lives.
The COVID-19 pandemic has already overwhelmed the sanitary capacity. Additional therapeutic arsenals, albeit untested in the given context but previously proven to be efficacious in a related clinical context, that could reduce the morbidity rate are urgently needed. A decrease of Heart Rate Variability (HRV) is a validated bad prognosis marker in sepsis and acute respiratory distress syndrome. In contrast, auricular vagus nerve stimulation was proven not only to increase HRV values in healthy Humans, but also to reduce sepsis and increase survival, both significantly, in experimental models. Moreover, the heavy viral infection within the brainstem of deceased patients suggests that the neuroinvasive potential of SARS-CoV2 is likely to be partially responsible for COVID-19 acute respiratory failure and may bear relevance in tailoring future treatment modalities. Interestingly, the vagus nerve (or tenth cranial nerve) connects bidirectionally the brainstem to various internal organs including the lung and to one external organ, namely, the outer ear. Hence, the impact of auricular vagus nerve stimulation through semi-permanent needles will be studied, mostly used so far for pain alleviation, on the outcome of COVID-19 inpatients within 15 days.
The mortality rate of the disease caused by the corona virus induced disease (COVID-19) has been estimated to be 3.7% (WHO), which is more than 10-fold higher than the mortality of influenza. Patients with certain risk factors seem to die by an overwhelming reaction of the immune system to the virus, causing a cytokine storm with features of Cytokine-Release Syndrome (CRS) and Macrophage Activation Syndrome (MAS) and resulting in Acute Respiratory Distress Syndrome (ARDS). Several pro-inflammatory cytokines are elevated in the plasma of patients and features of MAS in COVID-19, include elevated levels of ferritin, d-dimer, and low platelets. There is increasing data that cytokine-targeted biological therapies can improve outcomes in CRS or MAS and even in sepsis. Tocilizumab (TCZ), an anti-IL-6R biological therapy, has been approved for the treatment of CRS and is used in patients with MAS. Based on these data, it is hypothesized that TCZ can reduce mortality in patients with severe COVID-19 prone to CRS and ARDS. The overall purpose of this study is to evaluate whether treatment with TCZ reduces the severity and mortality in patients with COVID-19.
Primary Objective: To assess the effect of hydroxychloroquine versus placebo on nasopharyngeal SARS-CoV-2 viral load in outpatient adults with COVID-19 Secondary Objectives: - To assess the effect of hydroxychloroquine versus placebo on clinical signs and symptoms and progression of disease in outpatient adults with COVID-19 - To assess the safety and tolerability of hydroxychloroquine in outpatient adults with COVID-19
The Severe Acute Respiratory Syndrome COronaVirus 2 (SARS-CoV2) is a new and recognized infectious disease of the respiratory tract. Most cases are mild or asymptomatic. However, around 5% of all patients develop Acute Respiratory Distress Syndrome (ARDS), which is the leading mortality cause in these patients. Corticosteroids have been tested in deferent scenarios of ARDS, including viral pneumonia, and the early use of dexamethasone is safe and appears to reduce the duration of mechanical ventilation in ARDS patients. Nevertheless, no large, randomized, controlled trial was performed evaluating the role of corticosteroids in patients with ARDS due SARS-CoV2 virus. Therefore, the present study will evaluate the effectiveness of dexamethasone compared to control (no corticosteroids) in patients with moderate and severe ARDS due to SARS-CoV2 virus.
A new human coronavirus responsible for pneumonia, SARS-CoV-2, emerged in China in December 2019 and has spread rapidly. COVID-19, the disease caused by this virus, has a very polymorphous clinical presentation, which ranges from upper respiratory tract infections to acute respiratory distress syndrome. It may appear serious straightaway or may evolve in two stages, with a worsening 7 to 10 days after the first clinical signs, potentially linked to a cytokine storm and accompanied by a high risk of thrombosis. The global mortality rate of COVID-19 is between 3% and 4%, with severe forms being more frequent among older patients. Management is symptomatic as no antiviral treatment has demonstrated any clinical benefit in this condition. Hydroxychloroquine is a derivative of chloroquine commonly used in some autoimmune diseases, such as systemic lupus erythematosus. It is active in vitro in cellular models of infection by many viruses such as HIV, hepatitis C or SARS-CoV. However, its interest in viral infections in humans has not been demonstrated. Very recently, a preliminary uncontrolled study evaluated the effect of hydroxychloroquine on viral shedding in subjects with COVID-19. Among 20 patients treated with hydroxychloroquine at a dose of 600 mg per day, the percentage of patients with detectable SARS-CoV-2 RNA in the nasopharynx decreased from 100% at inclusion (start of treatment) to 43% six days later. In comparison, 15 of 16 untreated patients had a positive RT-PCR six days after inclusion. Furthermore, hydroxychloroquine has immunomodulating and anti-inflammatory properties, which could theoretically prevent or limit secondary worsening. The research hypothesis is that treatment with hydroxychloroquine improves prognosis and reduces the risk of death or use for invasive ventilation in patients with COVID-19.
This is a phase 3, randomized, double-blind, placebo-controlled multicenter study to evaluate the efficacy and safety of colchicine in adult patients diagnosed with COVID-19 infection and have at least one high-risk criterion. Approximately 6000 subjects meeting all inclusion and no exclusion criteria will be randomized to receive either colchicine or placebo tablets for 30 days.
This study explores whether patients acutely hospitalized may have shorter hospitalization and fewer admittances at Intensive Care Units by treatment with azithromycin and hydroxychloroquine.
The additional effect of personalized health education compared to general education following the internationally accepted principles will be evaluated in the prevention of the serious course of the novel coronavirus infection. It is hypothesised that personalized health education provides a greater degree of lifestyle change, thus the risk of a serious course of infection decreases.
In vitro studies revealed that lopinavir/ritonavir and hydroxychloroquine have antiviral activity against Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, there is no clinical studies on the reduction of viral load in patients with COVID-19. This study investigate whether lopinavir/ritonavir or hydroxychloroquine reduces viral load from respiratory specimen in patients with mild COVID-19.
