Coronavirus-2019 disease (COVID-19) and community-acquired pneumonia are significant problems of modern medicine. Pneumonia is the most common severe complication of COVID-19. But at the same time, COVID-19 is not the only cause of community-acquired pneumonia. Moreover, pneumonia is only one of the numerous possible severe complications of COVID-19. Medical centers specialized for the hospital treatment of patients with severe COVID-19 and community-acquired pneumonia were organized in different regions of Russia during coronavirus pandemic-2020. The indications for hospitalization to one of these centers based in the National Medical and Surgical Center (NMSC) are: confirmed or suspected severe COVID-19 or community-acquired pneumonia. A prospective medical registry of such patients hospitalized to NMSC, is intended to analyze and compare their clinical and instrumental data, co-morbidity, treatment, short-term and long-term outcomes in real clinical practice. Stage 1. Hospital treatment in NMSC Duration of this stage: from the date of admission to the hospital up to the date of discharge from the hospital / or up to the date of death during the reference hospitalization. The date of admission to the hospital will be the date of enrollment to the study. Evaluation of electronic health record data using the Medical Information System (MIS). Assessment of the outcomes of the hospital phase (discharge from the hospital, death) and significant events (acute respiratory and pulmonary failure, requiring mechanical ventilation; cardiovascular events - myocardial infarction, cerebral stroke, acute heart failure, paroxysmal heart rhythm disturbances, bleedings, thrombosis of large vessels and thromboembolic complications). A survey of patients to clarify data on risk factors, somatic diseases, and drug therapy before hospitalization. COVID-19 was diagnosed when severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was confirmed by Polymerase chain reaction (PCR). Pneumonia was confirmed according to computerized tomography (CT) data. Stage 2. Prospective outpatient follow-up for 24 months Duration of this stage: 24 months after discharge from the hospital This work will be delivered by investigators from the National Medical Research Center for Therapy and Preventive Medicine. Evaluation of long-term outcomes and events among residents of Moscow and the Moscow Region according to a patient survey (contact by phone for 30-60 days, 6 months, 12 and 24 months after discharge from the hospital) and medical records.
1.5. Why this clinical study? The prevalence of seropositivity following SARS-CoV 2 infection might have its own potential benefits in terms of predicting the end of pandemic and the validity of herd immunity. It is not clear if SARS-CoV 2 infection would have a long-lasting antibody-mediated immunity, and if the antibodies' persistence is dependent on disease severity.depends on the severity of illness. If evidence is provided about the persistence of antibodies that is reflective of the protective immune response, serodiagnosis will be an important tool to identify individuals with various risk for infection, and those who are in need of receiving the forthcoming vaccines. The here proposed prospective clinical study will test the prevalence of seropositivity following SARS-CoV 2 infection in critically ill patients compared to those who do not require intensive care unit (ICU) admission or invasive ventilation with respect to the IgM and IgG levels.
This is a phase 2, prospective, multicenter, randomized, double blind, placebo controlled, parallel group study to evaluate the safety and efficacy of intravenous (IV) administration of CSL324, administered in combination with SOC treatment, in subjects with COVID 19. For the purposes of this study, standard of care (SOC) may include any written or established treatment protocol followed at the study site for the treatment of severe COVID-19 or its complications, including off-label use of marketed pharmaceutical products and / or products with emergency use authorization granted for the treatment of COVID-19 (ie, not yet marketed) (eg, remdesivir).
An estimated 22% of the global population is at an increased risk of a severe form of COVID-19, while one in four coronavirus patients admitted to intensive care unit will develop a pulmonary embolism. A major public health question remains to be investigated: why COVID-19 is mild for some, critically severe for others and why only a percentage of COVID-19 patients develop thrombosis, despite the disease's proven hypercoagulable state? Patients' intrinsic characteristics might be responsible for the deep variety of disease forms. Our study aims to assess the validity of the hypothesis according to which underlining genetic variations might be responsible for different degrees of severity and thrombotic events risks in the novel coronavirus disease. Moreover, we suspect that prothrombotic genotypes occuring in the genes that encode angiotensin-converting enzyme (ACE-DEL/INS) and angiotensinogen (AGT M235T) are involved in the unpredictable evolution of COVID-19, both in terms of severity and thrombotic events, due to the strong interactions of SARS-CoV-2 with the renin-angiotensin-aldosterone system (RAAS). Therefore, we also aim to assess the validity of the theory according to which there is a pre-existing atypical modulation of RAAS in COVID-19 patients that develop severe forms and/or thrombosis. Our hypothesis is based on various observations. Firstly, there is a substantial similarity with a reasonably related condition such as sepsis, for which there is a validated theory stating that thrombophilic mutations affect patients' clinical response. Secondly, racial and ethnic genetic differences are responsible for significant dissimilar thrombotic risks among various nations. Thirdly, an increase in stroke incidence has been reported in young patients with COVID-19, without essential thrombosis risk factors, favoring the idea that a genetic predisposition could contribute to increase the thrombotic and thromboembolic risk. Fourthly, the plasminogen activator inhibitor (PAI)-1 4G/5G inherited mutation was found to be responsible for a thrombotic state causing post-SARS osteonecrosis.
Effectiveness of the use of Tenofovir/Emtricitabine in addition to personal protective equipment for the prevention of the transmission of SARS-COV-2 to health care personnel. A Randomized Clinical Trial. This is an experimental study whose aim is to evaluate the effectiveness of a drug to prevent infection with the virus that causes COVID-19 (SARS-CoV-2), in health care workers. The drug under study is Tenofovir /Emtricitabine, a well-known antiretroviral, which is safe and is used as prophylaxis and treatment for HIV and other viral infections such as Hepatitis. Several laboratory-based studies indicate that this drug has the potential to inhibit SARS-CoV-2 replication. In addition, one study in HIV infected persons found that those taking Tenofovir /Emtricitabine tended to have a lower occurrence of COVID-19. In this study, we will compare the occurrence of infection with SARS-CoV-2/ COVID19 in health care workers between those assigned to an intervention group and those assigned to a control group. The intervention group will receive Tenofovir /Emtricitabine during 60 days in addition to the use of personal protective equipment (PPE), and the control group will receive a placebo during 60 days in addition to the use of personal protective equipment (PPE). The study will recruit 950 health professionals above 18 and less than 70 years, working in the emergency room, COVID wards and intensive care units of seven hospitals in Colombia. To make the comparison groups very similar, the participants will be assigned through a random mechanism to either the intervention (475), or the control (475) groups. In order to prevent biases in the evaluation of the results, neither the participants nor the clinical investigators, data managers, analysts and support personnel will know which intervention the participants are receiving. To determine the occurrence of infection with the virus the study will use both molecular tests that detect the presence of viral genes in respiratory secretions, and serological tests that detect the response of the immune system to the virus. The study will evaluate also the safety of this drug determining the occurrence of adverse events.
Drug studies often look at the effect one or two drugs have on a medical condition, and involve one company. There is currently an urgent need for one study to efficiently test multiple drugs from more than one company, in people who have tested positive for COVID-19 but who do not currently need hospitalization. This could help prevent disease progression to more serious symptoms and complications, and spread of COVID-19 in the community. This study looks at the safety and effectiveness of different drugs in treating COVID-19 in outpatients. In Phase II, participants in the study will be treated with either a study drug or with placebo. In protocol version 7.0, participants in Phase III of the study will be treated with either a study drug or active comparator drug. Participants assigned to the bamlanivimab agent/placebo arm and will have 28 days of intensive follow-up following study drug administration, followed by limited follow-up through 24 weeks in phase II and in phase III. All other investigational agents and their corresponding placebo arms will involve 28 days of intensive follow-up, followed by limited follow-up through 72 weeks in phase II and phase III. Additional study visits may be required, depending on the agent.
Severe pneumoniae related to Coronavirus Disease (COVID-19), had a high in-hospital mortality; this condition are worst in subjects with acute kidney disease (AKI); conditioning increased mortality, days of assisted mechanical ventilation (AMV), increased nosocomial infections and high costs. We need many studies for determinated the risk factors for AKI in subjects with COVID-19. This study pretends identify the incidence of AKI in subjects with severe pneumoniae by COVID-19, describe the role of some biomarkers in the physiopathology of AKI-COVID-19; and determine the evolution of urinary biomarkers during hospitalization, like neutrophil gelatinase-associated lipocalin (NGAL), tissue inhibitor of metalloproteinases-2 (TIMP-2), insulin-like growth factor binding protein-7 (IGFBP7), and interleukin-6 (IL-6) and the progression of viruria of Severe Acute Respiratory Syndrome (SARS) related to CoronaVirus 2 (CoV2) in subjects with or without AKI.
Emerging in China in December 2019, Covid-19, whose pathogen is SARS-Cov-2, was declared a global pandemic in March 2020. The clinical presentation is highly variable, ranging from asymptomatic forms to acute respiratory distress and even death. Transmission is by droplet route, with an R0 of approximately 3. Rapidly, population protection measures were put in place by governments, including the confinement of all persons whose functions were not considered essential and the closure of educational institutions. Health care institutions are places at risk of Covid-19 transmission and hospital staff are particularly exposed, either through direct contact with patients, contact with exposed persons or through the environment. In order to protect personnel, hygiene measures were immediately recalled and reinforced. During the period of containment, the majority of students from the Lyon-Bron Military Medical Schools were sent as reinforcement in Army Training Hospitals and in the Military Reanimation Unit (Mulhouse). Some students developed symptomatic forms of SARS-Cov-2 infection, documented by positive PCR, during Operation Resilience or on their return from the mission. The Lyon-Bron Military Medical Schools staff, exposed both to the initial phase of the epidemic and to national protection measures, represent an extremely interesting population for understanding the epidemiological dynamics of the virus.
