RESUMO
Rationale: Invasive tracheobronchial aspergillosis (ITBA) is an uncommon but severe clinical form of invasive pulmonary aspergillosis in which the fungal infection is entirely or predominantly confined to the tracheobronchial tree.Objectives: To analyze the diagnostic and prognostic differences between tracheobronchial aspergillosis and pulmonary aspergillosis without tracheobronchial lesions among patients admitted to the ICU with severe influenza.Methods: This retrospective, observational study included critically ill patients with influenza associated with pulmonary aspergillosis from three hospital ICUs between 2010 and 2019. Patient characteristics and clinical and mycologic data at admission and during ICU stay were collected in a database to evaluate variables in the two groups.Measurements and Main Results: Thirty-five patients admitted to the ICU with severe influenza and pulmonary aspergillosis were included. Ten patients were included in the group with ITBA (n = 10 of 35; 28.6%), and 25 patients were included in the group without ITBA. The group with ITBA comprised more patients with active smoking, diabetes mellitus, and higher severity scores (Simplified Acute Physiology Score II). Ninety-day mortality rates in the groups with and without ITBA were 90% and 44%, respectively (P = 0.02). Moreover, significantly higher serum 1,3-ß-d-glucan and galactomannan and BAL fluid galactomannan concentrations were observed in the group with ITBA compared with the group without ITBA (P < 0.0001, P = 0.003, and P = 0.008, respectively).Conclusions: ITBA was associated with higher severity scores, mortality, and serum and BAL fluid galactomannan and 1,3-ß-d-glucan concentrations than invasive pulmonary aspergillosis without tracheobronchial lesions. ITBA should be systematically researched by bronchoscopic examination in ICU patients with concomitant pulmonary aspergillosis and influenza.Clinical trial registered with www.clinicaltrials.gov (NCT04077697).

OBJECTIVE: To report the hemodynamic effect of to the molecular adsorbent recirculating system (MARS™) therapy for patients in refractory vasoplegic shock due to calcium channel blocker (CCB) poisoning. METHODS: We report a retrospective cohort of patients who were hospitalized for CCB poisoning with refractory vasoplegic shock and treated by MARS therapy, at Amiens Hospital University, from January 2010 to December 2019. Improvement in hemodynamic was assessed by dynamic changes in mean arterial pressure (MAP) and norepinephrine levels over a 24-h period after MARS therapy. Cardiac function was assessed by transthoracic echocardiography. RESULTS: MARS therapy was performed on seven patients for CCB poisoning. CCB poisoning included nicardipine (n = 3, 43%) amlodipine (n = 3, 43%), and verapamil (n = 1, 14%). The median time to start MARS therapy was 24 [14-27] h after drug ingestion and 6 [2-9] h after ICU admission. Cardiac output was preserved for all patients. MAP values improved from 56 [43-58] to 65 [61-78] 16 mmHg (p = 0.005). Norepinephrine dose significantly decreased from 3.2 [0.8-10] µg/kg/min to 1.2 [0.1-1.9] µg/kg/min (p = 0.008) and lactate level decreased from 3.2 [2.4-3.4] mmol/l-1 to 1.6 [0.9-2.2] mmol/l-1 (p = 0.008). The median length of ICU stay was 4 (2-7) days and hospital stay was 4 (4-16) days. No complication related to the MARS therapy were reported. No patient died and all were discharged from the hospital. CONCLUSION: We reported the largest case-series of MARS therapy for refractory vasoplegic shock due to CCB poisoning. We observed that MARS therapy was associated with an improvement of hemodynamic parameters.

BACKGROUND: Data on microcirculatory pattern of COVID-19 critically ill patients are scarce. The objective was to compare sublingual microcirculation parameters of critically ill patients according to the severity of the disease. METHODS: The study is a single-center prospective study with critically ill COVID-19 patients admitted in ICU. Sublingual microcirculation was assessed by IDF microscopy within 48 hours of ICU admission. Microcirculatory flow index (MFI), proportion of perfused vessel (PPV), total vessel density (TVD), De Backer score (DBS), perfused vessel density (PVD) and heterogeneity index (HI) were assessed. Patients were divided in 2 groups (severe and critical) according to the World health organization definition. FINDINGS: From 19th of March to 7th of April 2020, 43 patients were included. Fourteen patients (33%) were in the severe group and twenty-nine patients (67%) in the critical group. Patients in the critical group were all mechanically ventilated. The critical group had significantly higher values of MFI, DBS and PVD in comparison to severe group (respectively, PaCO2: 49 [44-45] vs 36 [33-37] mmHg; p<0,0001, MFI: 2.8 ± 0.2 vs 2.5 ± 0.3; p = 0.001, DBS: 12.7 ± 2.6 vs 10.8 ± 2.0 vessels mm-2; p = 0.033, PVD: 12.5 ± 3.0 vs 10.1 ± 2.4 mm.mm-2; p = 0.020). PPV, HI and TVD were similar between groups Correlation was found between microcirculatory parameters and PaCO2 levels. CONCLUSION: Critical COVID-19 patients under mechanical ventilation seem to have higher red blood cell velocity than severe non-ventilated patients.

We report the case of an 80-year-old woman who presented one episode of cardiopulmonary arrest and two episodes of acute airway obstruction. We found in this patient the presence of tracheomalacia caused by megaesophagus compression secondary to achalasia probably responsible for episodes of acute airway obstruction and cardiopulmonary arrest.
RESUMO
Coronavirus disease-19 (COVID-19)-related severe acute respiratory distress syndrome can lead to acute cor pulmonale. We report a case of acute cor pulmonale secondary to severe COVID-19 acute respiratory distress syndrome diagnosed with transesophageal echocardiography. Almitrine infusion allowed rapid enhancement of right ventricular function as well as improvement in oxygenation. (Level of Difficulty: Intermediate.).
