Filter by:This is a randomized controlled trial of the efficacy of an individualized, progressive, exercise program (strength, cardiovascular, and breathing exercises) in recovering people from the post-COVID-19 syndrome (i.e., patients who present symptoms >12 weeks once the acute phase of the disease is over).
The purpose of the study is to assess the effectiveness of Spikogen vaccine when used as a 3rd or 4th dose booster in adults who have been previously vaccinated with any Covid-19 vaccine types, including mRNA vaccine, adenoviral vector vaccines, recombinant protein vaccines, or inactivated virus vaccines.
This is a prospective, multicenter, randomized, controlled, superiority clinical trial. It is expected that the test group would have better effectiveness than the control group in the primary evaluation indicator (time to negative viral nucleic acid detection from the start of study treatment). The test group will use the investigational medical device Hydrogen-Oxygen Generator with Nebulizer (Shanghai Asclepius Meditec Co., Ltd.) + basic treatment (the investigator provides corresponding symptomatic support treatment based on the condition of the patients), and the control group will use the hospital routine oxygen supply equipment (wall oxygen or cylinder oxygen) + basic treatment, to evaluate the effectiveness and safety of the investigational medical device Hydrogen-Oxygen Generator with Nebulizer for adjuvant treatment of COVID-19 patients.
The purpose of this retrospective study is to evaluate the effectiveness of CPM nasal spray as part of the treatment of COVID-19 and its impact on clinical symptoms. Two cohort groups will be compared (CPM vs. standard care). The hypothesis to be tested is that patients treated with CPM nasal spray showed more rapid clinical improvement than those treated with standard of care alone. Clinical improvement will be evaluated by the total number of days with the manifestation of COVID-19 symptoms, including cough, nasal congestion, ageusia, and anosmia, among others. The rate of hospitalization between the cohorts will also be evaluated.
An open label, non-randomized pilot study in kidney transplant recipients who received a completed primary series and bivalent booster of mRNA based COVID-19 vaccine and have =<2500 U/mL SARS-CoV-2 S antibody concentration using the Roche Elecsys(R) anti-RBD assay. Up to 80 participants will be enrolled in this study. Eligible participants will receive a dose of the Sanofi-GSK monovalent (B.1.351) CoV2 preS dTM-AS03 COVID-19 vaccine candidate.. The primary objective is to determine whether a booster dose of the Sanofi-GSK monovalent (B.1.351) CoV2 preS dTM-AS03 COVID-19 vaccine will elicit an increased SARS-CoV-2 antibody response in participants who have failed to maintain an antibody titer >2500 U/mL (using the Roche Elecsys(R) anti-RBD assay) to 2 or more doses of mRNA based COVID-19 vaccine
The most severe infectious episodes are managed in intensive care. Classically, a distinction is made between sepsis, an infection associated with an inappropriate, excessive response of the immune system, responsible for organ dysfunction, and septic shock, during which, within the potential dysfunctions, hemodynamic alteration is central, requiring the introduction of catecholamines. The seriousness of these disorders, particularly because of their potential short-term severity, requires immediate treatment. The treatment of severe infections is based on the control of microbial proliferation, particularly bacterial. In this context, the speed of antibiotic therapy is associated with patient prognosis. If the administration of antibiotic therapy is an emergency during severe infections, particularly in situations of septic shock, its choice is decisive in the effectiveness of management and in the prognosis of the patient. Prior to microbiological results, antibacterial treatment is probabilistic. In spite of these numerous parameters, failure of probabilistic antibiotic therapy, due to a spectrum unsuited to the pathogens, is described in 15 to 30% of cases. In order to limit the risk of inappropriate treatment, it is recommended that broad-spectrum antibiotic therapy be used in states of shock of infectious origin. Because of their bactericidal properties, their kinetics of effectiveness, their marked post-antibiotic effect, their bioavailability in the plasma sector, and their synergy with beta-lactams, aminoglycosides are often recommended in combination in the initial probabilistic treatment. Despite numerous studies and extensive international experience with aminoglycosides, their real value in the management of severe infections remains uncertain, leading to contradictory information depending on whether one is interested in their benefit in the treatment of identified infections or in the probabilistic treatment of severe conditions. During the management of severe intensive care patients, the pharmacokinetics of drugs, especially antibiotics, are considerably modified. As a result, monitoring of plasma, or better, tissue concentrations of antibiotics is suggested by learned societies, although their practical realization is still very limited by numerous obstacles. Misuse of aminoglycosides is associated with a risk of acute renal failure, centered on the tubular toxicity of the antibiotic. While the risks associated with inappropriate frequency of administration are currently modest, those associated with high peak concentration, responsible for an increase in the duration of renal exposure, are not well known. COVID-19 is also associated with a high risk of impaired renal function. The effect of aminoglycoside administration in the context of COVID-19 remains unknown. Our goal is to determine whether the presence of COVID-19 associates with an elevated risk of renal failure when prescribing aminoglycoside.
Clinical trial with randomized allocation in two arms (BCG vaccine versus placebo) of volunteers at risk but not yet infected nor vaccinated against SARS-CoV-2. Initially will be evaluated whether BCG has a protective role against severe form of the disease. After participants are vaccinated against COVID-19, it will be evaluated whether BCG favors the vaccine's efficacy. Volunteers will be recruited in three Brazilian states, with at least 250 seronegative in each group. The BCG-trained immunity stimulus will be investigated by assessing cytokines at D0 and D60 in a subsample of 50 participants per group. Until being vaccinated against COVID-19, the participants will be followed for up to 6 months, with visits scheduled every 2 months for interviews and immunoglobulin G (IgG) anti-SARS-CoV-2 antibodies. Those who become symptomatic at any time during the follow-up will be guided and monitored remotely daily until the end of their clinical evolution. After being vaccinated against COVID-19, visits to participants will be adjusted for the time of vaccination (VD), 20 days after the 1st dose (P1) and at least 30 days (P2) after the 2nd dose, with the aim of comparing the efficacy of the anti-SARS-CoV-2 vaccine in the two groups in the short and medium term. The study's conclusions on the efficacy of BCG in preventing severe COVID-19 will be based on: incidence of SARS-Cov-2 infection (defined as the emergence of IgG over the follow-up period); incidence of illness by COVID-19 (defined as the presence of symptoms among infected participants); intensity and duration of symptoms between cases of COVID-19 and frequency and duration of hospitalizations for COVID-19 in each group. The occurrence, type, frequency and intensity of adverse effects associated with vaccination of adults with BCG will be reported. The study's conclusions regarding the effect of BCG on efficacy of vaccines against COVID-19 will be based on: frequency of anti-SARS-CoV-2 neutralizing antibodies after the vaccine' 1st and 2nd doses in both groups.
Performance of the LumiraDx SARS-CoV-2 Ag ULTRA assay will be assessed by comparison to a reference method
This is a Phase III, randomized, placebo-controlled, observer-blinded, parallel-group, multi-center study to assess the safety, reactogenicity, and immunogenicity of heterologous booster vaccination of SK SARS-CoV-2 recombinant protein nanoparticle vaccine (GBP510) adjuvanted with AS03 in adults aged 18 years and older.
This study is to explore the safety and efficacy of using UCMSC01 in patients with COVID-19 infection via IV stem cell administration. The novelty of the current UMSC01 treatment is the single IV infusion of UMSC01 to the worldwide emergency outbreaks of COVID-19. We hypothesize that sufficient UMSC01 retention in lung may modulate the systemic inflammatory responses.
