High Flow Nasal Cannula HFNC In Covid-19 Patients

Many non-invasive ventilatory choices are available for COVID-19 patient who are having mild to moderate respiratory distress and their use will decrease the chance of ICU admission, intubation and mechanical ventilation in severe cases of COVID-19. However, all these respiratory supports and oxygen supply devices are aerosol generating and their selection should be precised enough to control nosocomial spread. High flow nasal cannula HFNC is a device that delivered the warmed and humid air on high flow rate through nose. It is used to treat severe respiratory distress in COVID-19 patients, a non-invasive ventilatory approach which is relative comfortable by using humidified and pre-heated air containing large concentration of oxygen. In acute respiratory failure HFNC is proven to be very effective and it also reduced the need of mechanical ventilation in severe patients. Apart from the supply of oxygen, HFNC generating positive airway pressure and decreasing the rebreathing from anatomical dead space. Prone position is also a save therapy and has been proven to be effective for refractory hypoxia by increasing tidal volume, oxygenation and diaphragmatic functions in ARDS patients. Recent studies showed that prone positioning and HFNC might avoid the prerequisite of intubation in moderate to severe patients of ARDS and as a result it decreases the nosocomial infection in physicians who are doing these aerosol generating procedures.

Clinical Trial Evaluating the Effect of BCG Vaccination on the Incidence and Severity of SARS-CoV-2 Infections Among Healthcare Professionals During the COVID-19 Pandemic in Poland

Countries that have not carried out universal mass vaccination against tuberculosis (BCG) have been shown to have higher incidence and death rates due to COVID-19 than countries with mass, long-term BCG immunization programmes. The aim of the study is to answer the following questions: Does BCG vaccination affect the course of COVID-19 (number of cases/deaths/severity of symptoms)? Will the course of COVID-19 be milder among subjects with a negative TB skin test (PPD RT 23 SSI) after an additional dose of BCG than in case of non-vaccinated subjects? Do people with a positive TB skin test have a milder course of COVID-19 infection than people with a negative test result? A multicenter, randomized, partially blinded, placebo-controlled study will be conducted in Rzeszow/Krakow/ Katowice/Warsaw on a group of 1000 volunteers, health care workers according to the following schedule: V 0-1: inclusion/informed consent/interview; V2: administration of TB skin test/anti-SARS-CoV-2 IgG test/serum banking*; V3: TB skin test (TST) interpretation and subjects' division into three groups: (I) positive TST - observation; (II) negative TST- BCG-10 vaccination; (III) negative TST - placebo. Division into groups II and III based on randomisation; V4: serum banking*. Parallel beginning from V3, weekly telephone monitoring participants' health status; In case of COVID-19 symptoms a nasopharyngeal swab to confirm SARS-CoV-2 infection + serum banking*. V5: 3 months after vaccination at the end of the study: history/anti-SARS-CoV-2 IgG test, serum banking*. Statistical analysis - comparison of the course of COVID-19 in groups: (I) with positive TST + observation, (II) with negative TST + BCG, (III) with negative TST + placebo - should demonstrate whether mass BCG vaccination has an impact on the incidence and course of COVID-19. * to measure the level of cytokines involved in cell-mediated immunity process

The Containing Coronavirus Disease 19 (COVID-19) Trial

In recent months severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) has emerged as a novel human pathogen and, susceptibility amongst humans is presumed to be universal. Prevention measures of COVID-19 have included distancing, quarantines, use of facemasks in public places, and hand hygiene measures. Mandatory quarantines have also been applied on index cases and their contacts, as well as an active search for asymptomatic patients. Current strategies to reduce the spread of SARS-CoV-2 do not include measures that could prevent transmission prior to the onset of symptoms. Subjects infected with SARS-CoV-2 have been known to shed virus and be contagious for up to 5 days prior to developing symptoms ('pre-symptomatic transmission'). In fact, nearly 60% of all infected subjects can shed virus pre-symptomatically. Pre- or even asymptomatic shedding occurs across all age groups, contributing to the rapidly expanding pandemic. Post-exposure prophylaxis (PEP) using type 1 interferon (IFN) can potentially eliminate the spread of SARS-CoV-2. IFN could reduce the period of viral shedding by ~1 week. Since pre-symptomatic shedding of virus can start up to 5 days prior to symptom onset, our approach of a PEP intervention to all contacts recently exposed to a case could possibly entirely interrupt the spread of the virus, and with that, the pandemic. The current study focuses on prevention of the disease in addition to its treatment. Thus, the key distinction between these other trials and this study is that this study focuses on containing coronavirus (i.e. cause) in the community, rather than simply its treatment (i.e. consequence) in the individual. Viral spread could be eliminated through interventions effective at abolishing viral transmission. However, such post-exposure prophylaxis interventions, that is initiation of antiviral therapy in pre-infectious contacts to reduce or even eliminate such spread, must be safe since they are given to asymptomatic and possibly uninfected subjects. In none of the previous clinical trials of IFN therapy for SARS-CoV-2 have serious adverse events been recorded. Furthermore, the IFN chosen for this study (pegylated IFN 1b) has been extensively studied in clinical trials, and has been in clinical use for years for multiple sclerosis. Pegylated IFN formulations allow for weekly injections while maintaining serum levels and limiting dose-dependent side effects. Together these data support a sound safety profile for the planned intervention. The aim of this study is to ascertain whether IFN administered to index cases and household contacts of an index case, starting immediately following confirmed exposure (index case confirmed positive for SARS-CoV-2), will reduce duration of SARS-CoV-2 detectable by PCR in the index cases, and incidence of SARS-CoV-2 detectable by PCR in household contacts.
