Filter by:To better understand the immune response to SARS-CoV-2 infection, we devised a precision immunology approach to systematically study the immune function of different patient cohorts
Patients with comorbid condition are known to be at high risk of severe forms of Covid-19. It is highly probable that immunocompromised patients like solid organ transplant (SOT) recipients are also at risk of severe forms of Covid-19. For this purpose, The investigators conducted a nationwide multicentric and multiorgan Registry to collect data about all French SOT recipients who develop a SARS-CoV-2 infection. The aim is to describe the clinical, biological and virological characteristics of these patients and to give information about evolution and prognosis of these particular population
The present study will try to respond first in an initial phase, what is the minimum effective dose necessary of convalescent plasma for getting better in severly ill (not intubated) or very severely ill (intubated) patients. Once the dose will be determined by each type of patient group (severely ill vs. very severely ill) has been determined, phase 2 of the study will begin, where the safety and efficacy of the use of plasma will be evaluated based on clinical, imaging and laboratory criteria. So, our hypotheses are: 1. Is there a minimum effective dose to treat seriously ill patients with convalescent plasma with COVID-19? 2. the plasma dose with the minimum effective effect will improve the clinical, laboratory and clearance conditions of the presence of the virus in the severely ill patient?
Since December 2019 the world has been shaken with an enormous global threat: the Covid-19 pandemic. This new kind of coronavirus is generating an unprecedented impact both on the general population and on the healthcare systems in most countries. Health services are trying to expand their capacity to respond to the pandemic, taking actions such as increasing the number of beds; acquiring necessary equipment to provide intensive therapy (ventilators), and calling retired health professionals and health students so they can assist the overwhelmed health care workforce. Unfortunately, these organizational changes at health facilities, along with the fears and concerns of becoming ill with the virus or infecting their families, put an enormous emotional burden on workers in health services which may lead to negative outcomes on mental health in this population. Recent cross-sectional studies in China indicate that health service workers exposed to people with Covid-19 reported higher rates of depressive and anxious symptoms. This negative impact on mental health among health workers in China has also been informally reported in other countries where the Covid-19 pandemic has been devastating in its effects (such as Spain and Italy), as well as in countries where the pandemic is becoming a growing public health problem. This is particularly relevant in regions with fewer resources (Latin America, North Africa), where there are limited means and the response from the health system is usually insufficient. Moreover, it is necessary to study these negative effects longitudinally considering that some effects will appear over time (post-traumatic stress). The COVID-19 HEalth caRe wOrkErS (HEROES) study is a large, bottom-up, South-North initiative aimed to evaluate the impact of the COVID-19 pandemic on the mental health of health care workers (HCWs). HEROES encompasses a wide variety of academic institutions in 19 LMICs and 8 HICs, in partnership with the Pan American Health Organization (PAHO) and with support from the World Health Organization (WHO). The HEROES study is led by Dr. Rubén Alvarado at University of Chile, and Dr. Ezra Susser and Franco Mascayano at Columbia U Mailman School of Public Health.
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.
Infections with Corona-Viruses have shown to be a menace for patients with comorbidities such as hypertension, diabetes, cardiovascular disease or immunosuppression. Those are features almost every nephrological patient brings along, especially those on maintenance dialysis and those with renal transplant. Since the emergence of the novel coronavirus SARS-CoV-2 in November 2019 in Mainland China the fear for pandemic infections has increased. But not only is the course of infection itself important, the prevention of transmission to and by attending medical personnel should be put into perspective. Thus there is a lack of sufficient data of occult immunization or persistent state on immunization. In our study up to 400 health care personnel will be screened serologically for IgM, IgA and IgG against the SARS-CoV-2 virus. Blood and urine samples throughout 12 months will be sampled and analyzed. The aim of the study is to identify the rate of occult immunization and at the same time to gather data about the persistence of immune response to an infection with SARS-CoV-02. The results will help provide sufficient safety measures for health care providers and renal patients undergoing unavoidable clinical treatment.
The infection caused by COVID19 worldwide makes it necessary to monitor drugs administered for the treatment of patients hospitalized with SARS-CoV-2. In order to know more about the efficacy and safety of the treatments used, researchers from the Cantabrian health service have developed an observational study, in the form of an ambispective registry, in which clinical data from patients treated with the different drugs currently recommended by the Spanish Agency of Medicines and Health Products (SAMHP) and the Ministry of Health, or others that may arise, are collected and analyzed. Although the conduct of clinical trials is a priority at this time, we cannot lose the clinical experience that is currently being generated, which may allow us to improve the therapeutic strategies for future patients.
The overall objective of the study is to determine the therapeutic effect and tolerance of Eculizumab in patients with moderate, severe pneumonia or critical pneumonia associated with Coronavirus disease 2019 (COVID-19). Eculizumab is a terminal complement inhibitor that has been investigated for more than 10 years in numerous complement-mediated diseases. The study has a cohort multiple Randomized Controlled Trials (cmRCT) design. Randomization will occur prior to offering Eculizumab administration to patients enrolled in the CORIMUNO-19 cohort. Eculizumab will be administered to consenting adult patients hospitalized with COVID-19 either diagnosed with moderate or severe pneumonia requiring no mechanical ventilation or critical pneumonia requiring mechanical ventilation. Patients who will chose not to receive Eculizumab will receive standard of care. Outcomes of Eculizumab-treated patients will be compared with outcomes of standard of care-treated patients as well as with outcomes of patients treated with other immune modulators.
Translational, prospective / retrospective, non-profit, non-pharmacological study, with cohort characteristics. The study consists of two parts: the first to study epidemiological aspects of the spread of the disease and the second one to identify infection-related genetic factors.
We will evaluate low-dose pyridostigmine as add-on therapy to best medical care in patients with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection and its related Coronavirus Disease 2019 (COVID-19) who require hospitalization. Our hypothesis is that, in comparison to the placebo, pyridostigmine will reduce in at least 10% a composite outcome [death; mechanical ventilation; >2 point-increase in the SOFA score) by day 28. We will also evaluate interleukin (IL)-6 kinetics during the first 14 days of in-hospital stay. It is estimated that 25-33% of patients hospitalized for COVID-19 are admitted to intensive care units (ICU) for severe hypoxemia. The reported mortality in those with severe disease ranges between 38% and 49%. So far, there is no pharmacological therapeutic (or else) strategy known to reduce morbidity and mortality in these patients. Mortality in COVID-19 appears to be mediated not necessarily by the direct effect of the infection, but by the disproportionate inflammatory response of the host. Pyridostigmine is an old drug that, by inhibiting acetylcholine-esterase, the enzymatic machinery that degrades acetylcholine (ACh), results in increased ACh bioavailability. ACh, in turn, ligates to nicotinic-alpha7 receptors in macrophages and T cells, resulting in reduced overactivation of these immune cells. In experimental murine sepsis, this family of drugs has resulted in reduced inflammation and mortality. Human evidence is scarce for severe inflammatory conditions. However, recent evidence from our group and others indicates that pyridostigmine has an immunomodulatory effect in people living with HIV, resulting in elevation of CD4+ T cell counts, decreased immune activation, and reduction in inflammatory mediators. Altogether, this suggests that ACh-esterase inhibitors may act as immunomodulators during viral infections, potentially reducing the inflammatory cascade (the so-called "cytokine storm") observed in critically ill COVID-19 patients. At the proposed dose (60mg/d), the rate of minor adverse events is less than 5% with no reported serious adverse effects. From that perspective, we consider that pyridostigmine can function as an immuno-modulator and reduce morbidity and mortality in COVID-19-stricken patients, with the added value of a safe pharmacological profile. Moreover, as an old drug, re-purposing it for a novel indication may be a simpler, more efficient approach than developing a novel one from the ground up.
