Filter by:This study is observational and double blind. It evaluates the validity of presepsin (a serum biomarker of bacterial infections) as early biomarker of Ventilator Associated Pneumonia. It will be measured at day 0 (ICU admission) and every 48 hours in every patient with Sars-Cov 2 interstitial pneumonia requiring invasive mechanical ventilation (see inclusion ad exclusion criteria) until Day 30, ICU discharge or ICU death. There will be no change in clinical practice and in pneumonia diagnosis. We will examine how the elevation of presepsin level could be an early marker of ventilator associated pneumonia or a marker of bacterial pneumonia at ICU admission, before the microbiological results or clinical diagnosis.
No therapeutic agent is currently approved for the treatment of SARSCoV-2 infection. More importantly, no intervention is currently available to mitigate the progression of disease from mid/moderate to serve particularly in high risk patients. Recognizing this limitation and urgency of finding a treatment for COVID-19, the U.S. Food and Drug Administration (FDA) has issued an Emergency Use Authorization (EUA) to permit the emergencyuse of the unapproved product bamlanivimab or casirivimab + imdevimab for the treatment of mild to moderate coronavirus disease 2019 (COVID19) in adults and pediatric patients with positive results of direct SARS-CoV-2 viral testing who are 12 years of age and older weighing at least 40 kg, and who are at high risk for progressing to severe COVID-19 and/or hospitalization.
Creation of an Institutional Registry system for patients with confirmed COVID-19 infection with the collection of epidemiological data, risk factors, diagnosis, prognoses, treatment, follow-up and survival.
This is a single-centre, open-label, first-in-human, single ascending dose and multiple dose study to assess the safety, reactogenicity, and immunogenicity of the SC-Ad6-1 investigational product when administered via the intramuscular (IM), intranasal (IN) or inhaled (IH) route in healthy volunteers.
Passive immunotherapy is a therapeutic alternative used in a variety of infectious diseases including COVID-19. Equine polyclonal hyperimmune sera is a source of neutralizing antibodies against SARS-CoV-2 and a therapeutic alternative under investigation in COVID-19 patients. In the previous study NCT04610502 no significant variations were observed regarding efficacy and safety between two different pharmaceutical preparations of equine hyperimmune sera and adequate tolerability was reported with both investigational products. Formulations were produced through repeated immunization with viral recombinant proteins and contain either antibodies against SARS-CoV-2 S1 protein (S type) or a combination of viral proteins that included S1, N (nuclear), E (envelop) and M (membrane) (M type). Another investigation (NCT04494984) found that the administration of a pharmaceutical preparation similar to the S type produced clinical improvement in hospitalized patients with SARS-CoV-2 pneumonia, particularly those with severe disease. Aim: Evaluate the efficacy and safety of three different doses of an anti-SARS-CoV-2 hyperimmune equine serum formulation (S-type) as an addition to the standard therapeutic approach in adult hospitalized patients with a diagnosis of moderate or severe COVID-19, radiological findings consistent with pneumonia and a symptom onset period not exceeding 10 days. A total of 156 patients will be included and randomly divided into four groups, each group will receive a different dose of the investigational drug. On day 1, all participants will receive a single intravenous infusion containing the specified dose according to their assigned group. Clinical assessments, laboratory determinations that include: viral load, antibodies quantification, inflammatory and coagulation markers, cytokines levels as well as standard evaluations will be performed for each patient. Data will be collected for all groups on Days 0 to 7, 14 and 28 or at discharge after completion of treatment. The study will end for each participant on the day of discharge from the hospital.
The objective of this study is to determine the safety and immunogenicity of two different strengths (4 µg and 6 µg) of an inactivated COVID-19 Vaccine compared to placebo so that to demonstrate the safety and efficacy in prophylaxis of COVID-19
The CORSAAR study is an observational, prospective study to investigate the natural biology of COVID-19
The aim of this study is to evaluate the efficacy of dexamethasone in hospitalized adults with COVID-19 pneumonia who do not require supplementary oxygen on admission, but have high risk of developing acute respiratory distress syndrome (ARDS). This is a prospective, multicenter, phase 4, parallel-group, randomized and controlled trial that is open-label to investigators, participants and clinical outcome assessors. Eligible participants include adults (age 18 years or older), diagnosed with SARS-CoV-2 infection, evidence of infiltrates on chest radiography or computerized tomography, peripheral capillary oxygen saturation ≥94% and 22 breaths per minute breathing room air, and high risk of developing ARDS defined by a lactate dehydrogenase higher than 245 U/L, C-Reactive Protein higher than 100 mg/L, and absolute lymphocytes lower than 800 cells/µL. Eligible participants will meet two of the three before analytical criteria associated with severe COVID-19. Patients will provide written informed consent. Exclusion criteria include patients with a history of allergy to dexamethasone, pregnant or lactating women, oral or inhaled corticosteroids treatment within 15 days before randomization, immunosuppressive agent or cytotoxic drug therapy within 30 days before randomization, neutropenia <1000 cells/µL, human immunodeficiency virus infection with CD4 cell counts <500 cells within 90 days after randomization, dementia, chronic liver disease defined by ALT or AST ≥5 times the upper limit of normal, chronic kidney injury defined by a glomerular filtration rate ≤30 ml/min, hemodialysis or peritoneal dialysis, uncontrolled infection, and patients who are already enrolled in another clinical trial. Study participants will be randomized in a 1:1 ratio to receive dexamethasone base 6 mg once daily for seven days or standard of care. The primary endpoint is to prevent of development of moderate ARDS. Based on the Berlin criteria, moderate ARDS is defined by a PaO2/FiO2 ratio >100 mmHg and ≤200 mmHg. Study participants will be randomized in a 1:1 ratio to receive dexamethasone versus standard of care using a randomization platform. Included participants will be hospitalized at the time of randomization. The study will be undertaken at Infanta Leonor-Virgen de la Torre University Hospital, Enfermera Isabel Zendal Emergency Hospital, and Infanta Cristina Hospital, Madrid, Spain.
A large proportion of persons who have had COVID-19 have reported persisted symptoms as fatigue and dyspnea months post infection which affect activities of daily living. The aim of the study is to examine the feasibility and safety of a concentrated rehabilitation program with a mobile application follow-up for persons with persistent symptoms post COVID-19 infection. We will examine recruitment availability, adherence to the program, goal achievement, and resources requirements. Methods: A feasibility study with one group pre-post test design with 10-20 persons between 18-67 years, with persistent symptoms post COVID-19 will be included. The intervention is 3+ 1-2 days concentrated rehabilitation with a mobile application follow-up for 3 months. Following assessments wil be used: Cardiopulmonary exercise testing, lung function, functional performance tests, questionnaires regarding dyspnea, fatigue, anxiety, depression, work-status, health status, sleep behavior, physical activity level. Demographic data before and after the intervention will be presented. Focus group interview will be done with the participants. The interview will be analysed using systematic text condensation.
Convalescent plasma therapy has been recognized as safe and plasma transfusion is routinely used in clinical practice. A recent study showed that early administration of convalescent plasma can decrease the risk of complications in specific high-risk population. The aim of the present study is to offer convalescent plasma therapy to immunocompromised patients and older adults in the early phase of a SARS-Cov-2 infection in order to accelerate viral clearance and prevent complication
