IL-1 Receptor Antagonist Anakinra in the Treatment of COVID-19 Acute Respiratory Distress Syndrome: A Retrospective, Observational Study.

The IL-1 receptor antagonist, anakinra, may represent a therapeutic option for acute respiratory distress syndrome (ARDS) associated with coronavirus disease 2019 (COVID-19). In this study, COVID-19 ARDS patients admitted to the Azienda Socio Sanitaria Territoriale of Lecco, Italy, between March 5th to April 15th, 2020, and who had received anakinra off-label were retrospectively evaluated and compared with a cohort of matched controls who did not receive immunomodulatory treatment. The primary end point was survival at day 28. The population consisted of 112 patients (56 treated with anakinra and 56 controls). Survival at day 28 was obtained in 69 patients (61.6%) and was significantly higher in anakinra-treated patients than in the controls (75.0 versus 48.2%, p = 0.007). When stratified by continuous positive airway pressure support at baseline, anakinra-treated patients' survival was also significant compared with the controls (p = 0.008). Univariate analysis identified anakinra usage (odds ratio, 3.2; 95% confidence interval, 1.47-7.17) as a significant survival predictor. This was not supported by multivariate modeling. The rate of infectious-related adverse events was similar between groups. In conclusion, anakinra improved overall survival and invasive ventilation-free survival and was well tolerated in patients with ARDS associated with COVID-19.

[The use of a "transgastric oblique" transesophageal echocardiographic view to visualize the right ventricular inflow-outflow tract. Clinical applications]. / La proiezione ecocardiografica transesofagea "transgastrica obliqua" per la visualizzazione del tratto di afflusso-efflusso ventricolare destro. Applicazioni nella pratica clinica.

This paper describes the transesophageal echocardiographic "oblique transgastric" view to assess the right ventricular inflow-outflow tract. With this approach it is possible to view the right atrium, tricuspid valve, right ventricular inflow and outflow tracts, and the main pulmonary artery. In 2 clinical cases we evaluated the clinical feasibility of this approach in the diagnostic phase; in 31 patients who underwent cardiac transplantation we examined the advantages of this noninvasive hemodynamic monitoring. An advantage of transgastric view compared with esophageal standard views at 30-60 degrees, is the feasibility to obtain the velocity-time integral of the outflow tract systolic flow to calculate cardiac output by the pulsed Doppler sample volume orientation, which in this view is parallel to pulmonary arterial flow; moreover, it is possible to evaluate pulmonary artery pressures from pulmonary and tricuspid regurgitation.
