ABSTRACT
BACKGROUND: The second wave of COVID-19 pandemic was not only associated with a rapid and severe surge in the number of cases but also limited availability of recommended medicines. Baricitinib has been known to reduce recovery time in COVID-19 pneumonia in association with remdesivir. Tofacitinib, with limited evidence, was used in severe COVID-19 pneumonia based on its similarity of action with baricitinib. METHODS: Data of all patients admitted to the COVID-19 intensive care unit in the month of April were accessed and analyzed. Data of patients who were on other immunomodulators, invasive ventilation, or suffering from end-stage organ diseases were excluded from the analysis. RESULTS: Out of 73 patients, data of 50 were analyzed. Twenty-five received tofacitinib and the other 25 were managed with standard of care. Age, comorbidities, and gender distribution between the two groups were similar. On day 7 of admission, the change in SpO2/FiO2 ratio was 1.26 ± 1 and 0.72 ± 1 in the tofacitinib group and control group, respectively. Similarly, a higher number of subjects in the control group showed worsening in the World Health Organization (WHO) ordinal scale (36 vs 12%, p = 0.01). The clinical objective improvement was similar in the two groups. The intubation rates in the tofacitinib group were significantly lower than that in the control group (32% vs 8%, p = 0.034). CONCLUSION: Tofacitinib, in this retrospective single-center experience, was found to be associated with reduced intubation rates and reduced worsening in the WHO ordinal scale. There was no difference in mortality in the two groups. HOW TO CITE THIS ARTICLE: Singh PK, Lalwani LK, Govindagoudar MB, Aggarwal R, Chaudhry D, Kumar P, et al.

ABSTRACT
AIM: To develop a device that can reduce the exposure of aerosols to healthcare workers (HCWs) who are working in coronavirus disease-2019 (COVID-19) critical units. BACKGROUND: Barrier enclosure has recently been proposed for use during intubations where the risk of aerosolization is high. In COVID-19 outbreak, use of noninvasive respiratory support is increasing. But at the same time, it is associated with high risk of aerosol generation, leading to infections among HCWs. We have made a modification in the intubation box and hence expanded its use with an aim to reduce COVID-19 exposure. TECHNIQUE: Vacuum suction tubing was attached to wall mount, and the other end of tubing was fixed, using adhesive surgical tapes, to the inside of the roof of barrier enclosure. Keeping the vacuum suction switched-on inside the box created a negative pressure while overall air flow is into the box from outside. This led us to believe that aerosols if generated are not contaminating patient's vicinity. Currently, we are using barrier enclosure boxes on all patients who are on noninvasive support (noninvasive ventilation or high-flow oxygen therapy). CONCLUSION AND CLINICAL SIGNIFICANCE: We believe that adding barrier enclosure with the above-mentioned negative-pressure modification will provide an opportunity to use noninvasive support widely, while at the same time, HCW's exposure to aerosols will be reduced.
