Active clinical trials for "COVID-19"

Infection with SARS-CoV-2 causes Corona Virus Disease (COVID-19). The most standard diagnostic method is reverse transcription-polymerase chain reaction (RT-PCR) on a nasopharyngeal and/or an oropharyngeal swab. The high occurrence of false-negative results due to the non-presence of SARS-CoV-2 in the oropharyngeal environment renders this sampling method not ideal. Therefore, a new sampling device is desirable. This proof-of-principle study investigates the possibility to train machine-learning classifiers with an electronic nose (Aeonose) to differentiate between COVID-19 positive- and negative persons based on volatile organic compounds (VOCs) analysis. Methods: between April and June 2020, participants were invited for breath analysis when a swab for RT-PCR was collected. If the RT-PCR resulted negative, presence of SARS-CoV-2 specific antibodies was checked to confirm the negative result. All participants breathed through the Aeonose for five minutes. This device contains metal-oxide sensors that change in conductivity upon reaction with VOCs in exhaled breath. These conductivity changes are input data for machine-learning and used for pattern recognition. The result is a value between -1 and +1, indicating the infection probability.

Methods: Single-center pilot study included PCR+ SARS-CoV2-patients, hospitalized from April to May 2020 in Puebla, Mexico. Comparative treatment with steroids plus CsA or steroids. Mild, moderate or severe pneumonia was measured by clinical, laboratory tests, lung damage score by computed tomography, and score for clinical improvement. Death rate was evaluated at 28 days.

The Coronavirus SARS CoV-2 (COVID-19) pandemic is causing a major global health crisis that is disrupting our hospital organizations and creating potential infectious risks for hospital staff on the front line when it comes to the support of infected people. In this context, the Paris Saint-Joseph Hospital Group (GhPSJ) very early on wanted to implement an institutional approach aimed, on the one hand, at enabling each of its employees at its two sites (Hôpital Paris Saint-Joseph (HPSJ), Paris 14ème and Hôpital Marie Lannelongue (HML), Le Plessis Robinson, 92) to access their serological status with regard to SARS-CoV-2 and, on the other hand, to identify the risk factors for contracting COVID-19. This collective approach consisted of an evaluation of its professional practices aimed at assessing the protective measures put in place to protect hospital personnel and identifying sources of potential improvement in the management of the infectious risk required to put in place in case of upcoming COVID-19 cases or any other epidemics in the future.

The study is a double-blind, randomised, placebo-controlled trial that will be conducted primarily in healthcare settings and other facilities directly involved in COVID-19 case management. We will recruit healthcare workers and other persons at risk of contracting COVID-19, who can be followed reliably for 5 months. The initial aim was to recruit 40,000 participants and we predict an average of 400-800 participants per site in 50-100 sites. The participant will be randomised to receive either chloroquine or placebo (1:1 randomisation), or to hydroxychloroquine or placebo (1:1 randomisation). A loading dose of 10mg base/kg (four 155mg tablets for a 60kg subject), followed by 155 mg daily (250mg chloroquine phosphate salt/ 200mg hydroxychloroquine sulphate) will be taken for 3 months. If the participant is diagnosed with COVID-19, they will take continue to take the study medication until: 90 days after enrolment (i.e., completion of kit) hospitalised due to COVID-19 disease (i.e., not for quarantine purposes) in which case they will stop, or advised to stop by their healthcare professional for other reasons Episodes of symptomatic respiratory illness, including symptomatic COVID-19, and clinical outcomes will be recorded in the Case Record Form during the follow-up period. This study is funded by Wellcome Trust Grant reference 221307/Z/20/Z.

As of March 2020, COVID-19 has become a global pandemic, halting athletic competition worldwide. Reports from China show a high prevalence of cardiac involvement in patients with severe SARS-CoV-2 infection. These cardiac forms were found to be closely associated with adverse outcomes. The use of Magnetic resonance Imaging (MRI) had allowed to show that cardiac dysfunction could be mediated by myocardial inflammation (i.e. myocarditis). The direct implication of the virus was demonstrated with Severe Acute Respiratory Syndrome (SARS)-CoV-2 being detected on myocardial biopsies in a patient with severe heart failure. The experience with other viruses causing acute myocarditis shows that there is a high rate of undetected injuries. Indeed, although severe heart failure can be present at the acute stage, acute viral myocarditis is most commonly pauci or asymptomatic, but still leaving occult myocardial scars visible on MRI, and exposing to higher risks of ventricular arrhythmia and sudden cardiac death over the long term. Although athletes are younger and have fewer comorbidities than the general population and therefore are at lower risk for severe disease or death, there is a critical and urgent need to assess the prevalence of occult scars in the population of high-level athletes returning to training after the SARS-CoV-2 pandemia.

Internet-based multidisciplinary interventions will be offered to participants suffering from longterm COVID-19 syndrome. Data will be collected by internet platform at Karolinska Institutet (BASS) before, after rehabilitation and at follow-up after 6 months. Both self-scored questionnaires and physical tests performed at home will be collected to understand the symptomatology, functioning and activity level. Rehabilitation during 8 weeks period will be given in groups as face-to-group, pre-recorded film sessions and by individual approach, the participants will use ExorLive app for physical activity.

During the COVID-19 pandemic, health employees are at high risk of infection. This study aimed to determine experiences with an aerosol box (AB), used with the aim of preventing contamination by droplets during internal jugular vein cannulation which requires close contact with COVID-19 patients, and the necessity to use this device.

This is a research study to evaluate the Sensitivity and Specificity of BIOZEK COVID-19 Antigen Rapid Test (Saliva) and BIOZEK COVID-19 Antigen Rapid Test (Nasopharyngeal Swab) on samples that are self-collected; and to perform analysis to compare results. In addition, to obtain RT-PCR test results, performed prior to enrollment, and compare all three results.

This 2-arm clustered, randomized community trial will test a multilevel, COVID-19 testing and linkage to care (eg, health insurance, medical appointments, community resources, contact tracing) intervention against a nontailored, attention-control condition on uptake of COVID-19 testing with adult African American church-affiliated members at 6 months. Contact tracing approval (beliefs and participation contact tracing) and COVID19 prevention behaviors will also be examined. Findings from this study could provide a theory-based, multilevel model for delivering scalable, wide-reaching COVID-19 testing and linkage to care services, including contact tracing, by supporting African American faith leaders with culturally-appropriate, easy-to-use tools and health agency partnerships.

Surfactant replacement therapy (SRT) improves oxygenation and survival in NRDS and some infant ARDS. SRT was tried in adult ARDS with conflicting results. Research by Filoche and Grotberg helped to understand the failure of previous clinical trials and yielded a strong scientific rationale for SRT success, now allowing to design a new administration protocol for SRT in adults, to be tested by this clinical trial in COVID-19 adult ARDS patients. Patients will be randomized to receive either a bronchial fibroscopy alone (with aspiration of secretions) or a bronchial fibroscopy with administration of 3 mL/kg of a solution of poractant alpha diluted to 16 mg/mL and distributed into each of the 5 lobar bronchi.
