Acute respiratory distress syndrome (ARDS) is characterized by a widespread inflammation of the lungs, causing severe hypoxemia. Several mediators have been associated with it and almost all of them are small enough to be filtrated through a nanomembrane. We present a case report of a 41-year-old man with myasthenia gravis in remission; he developed ARDS caused by pneumonia. Although he performed well on both non-invasive and invasive mechanical ventilation, his oxygenation continued to deteriorate. As a last resort of treatment, we decided to apply nanomembrane-based apheresis to cleanse his plasma from the harmful inflammatory mediators. After 3 sessions of plasmapheresis, his condition improved and he was successfully weaned from mechanical ventilation. The obtained results gave us ground to assume that the removal of bioactive molecules can be a useful adjunct to protective mechanical ventilation in ARDS.

Pasien COVID-19 related Acute Respiratory Distress Syndrome (CARDS) dengan gejala ARDS sedang hingga berat memerlukan Invasive mechanical ventilation (IMV) dan memiliki prognosis yang buruk dengan angka ARDS sekitar 75% serta 63% menerima Invasive mechanical ventilation (IMV) dengan tingkat kematian 59% . Tingginya angka kematian pasien CARDS mendapat terapi invasive mechanical ventilation (IMV) menyebabkan para praktisi kesehatan berusaha untuk menunda intubasi dan ventilasi mekanik secara dini sehingga Non Invasive Ventilation Mechanic (NIV), CPAP dan HFNC menjadi alternatif terapi dalam penanganan CARDS. Kasus: Perempuan usia 49 tahun, masuk ICU dengan diagnosa POH-4 Craniectomy evakuasi tumor sphenoid, Sepsis Syok dan Covid-19 terkonfirmasi. Pada pemeriksaan didapatkan hipoksemia dengan ARDS berat P/F ratio 112.1 mmHg dan gambaran pneumonia dextra dan efusi pleura dextra.  Sebelum pindah ke ICU Covid, pasien mendapatkan terapi HFNC FiO2 40% dengan flow 35 L/menit, RR 25, Saturasi 95%, ROX index 9,5. Pemeriksaan laboratorium didapatkan Wbc : 7.800/L, Hb: 8,1mg/dl, Plt : 131.000/mm3, Bilirubin total 1,3 mg/dl, bilirubin direct 0,83 mg/dl, Na/K/cl : 143/2,9/111, Procalcitonin : 11.2. Kesimpulan: Terapi oksigen dengan HFNC pada CARDS sedang sampai berat menjadi pilihan bijaksana dimana terapi HFNC dapat menunda intubasi dan IMV dengan outcome yang baik. Sebagaimana Surviving Sepsis/Society of Critical Care Medicine merekomendasikan HFNC sebagai pendekatan lini pertama.

<strong>Introduction:</strong> Acute Respiratory Distress Syndrome has a significant incidence and mortality at Intensive Care Units. Therefore, more studies are necessary in order to develop new effective therapeutic strategies. The authors have proposed themselves to characterize Acute Respiratory Distress Syndrome patients admitted to an Intensive Care Unit for 2 years.<br /><strong>Material and Methods:</strong> This was an observational retrospective study of the patients filling the Acute Respiratory Distress Syndrome criteria from the American-European Consensus Conference on ARDS, being excluded those non invasively ventilated. Demographic data, Acute Respiratory Distress Syndrome etiology, comorbidities, Gravity Indices, PaO2/FiO2, ventilator modalities and programmation, pulmonary compliance, days of invasive mechanical ventilation, corticosteroids use, rescue therapies, complications, days at<br />Intensive Care Unit and obits were searched for and were submitted to statistic description and analysis.<br /><strong>Results:</strong> A 40 patients sample was obtained, with a median age of 72.5 years (interquartile range = 22) and a female:male ratio of ≈1:1.86. Fifty five percent of the Acute Respiratory Distress Syndrome cases had pulmonary etiology. The mean minimal PaO2/FiO2 was 88mmHg (CI 95%: 78.5–97.6). The mean maximal applied PEEP was 12.4 cmH2O (Standard Deviation 4.12) and the mean maximal used tidal volume was 8.2 mL/ Kg ideal body weight (CI 95%: 7.7–8.6). The median invasive mechanical ventilation days was 10. Forty seven and one half percent of the patients had been administered corticosteroids and 52.5% had been submitted to recruitment maneuvers. The most frequent complication was Ventilator Associated Pneumonia (20%). The median Intensive Care Unit stay was 10.7 days (interquartile range 10.85). The fatality rate was 60%. The probability of the favorable outcome ‘non-death in Intensive Care Unit’ was 4.4x superior for patients who were administered corticosteroids and 11x superior for patients &lt; 65 years old.<br /><strong>Discussion and Conclusions:</strong> Acute Respiratory Distress Syndrome is associated with long hospitalization and significant mortality. New prospective studies will be necessary to endorse the potential benefit of steroid therapy and to identify the subgroups of patients that warrant its use.

Abstract Background The use of cytokine-blocking agents has been proposed to modulate the inflammatory response in patients with COVID19. Tocilizumab and Anakinra were included in the local protocol as an optional treatment in critically ill patients with acute respiratory distress syndrome (ARDS) by SARS-CoV2 infection. This cohort study evaluated the effects of therapy with cytokine blocking agents on in-hospital mortality in COVID19 patients requiring mechanical ventilation and admitted to intensive care unit. Methods The association between therapy with Tocilizumab or Anakinra and in-hospital mortality was assessed in consecutive adult COVID19 patients admitted to our ICU with moderate to severe ARDS. The association was evaluated by comparing patients who receive to those who did not receive Tocilizumab or Anakinra and by using different multivariable Cox models adjusted for variables related to poor outcome, for the propensity to be treated with Tocilizumab or Anakinra and after patient matching. Results Sixty-six patients who received immunotherapy (49 Tocilizumab, 17 Anakinra) and 28 patients who did not receive immunotherapy were included. The in-hospital crude mortality was 30,3% in treated patients and 50% in non-treated (OR 0,77, 95% CI 0,56-1,05, p=0,069). The adjusted Cox model showed an association between therapy with immunotherapy and in-hospital mortality (HR 0,35, 95% CI 0,16-0,77, p=0,009). This protective effect was further confirmed in the analysis adjusted for propensity score, in the propensity-matched cohort and in the cohort of patients with invasive mechanical ventilation within 2 hours after ICU admission. Conclusions Although important limitations, our study showed that cytokine-blocking agents seem to be safe and to improve survival in COVID-19 patients admitted to ICU with ARDS and the need of mechanical ventilation.

ABSTRACT Introduction: Acute respiratory distress syndrome (ARDS) in COVID-19 is associated with a high mortality rate, though outcomes of the different lung compliance phenotypes are unclear. We aimed to measure lung compliance and examine other factors associated with mortality in COVID-19 patients with ARDS. Methods: Adult patients with COVID-19 ARDS who required invasive mechanical ventilation at 8 hospitals in Singapore were prospectively enrolled. Factors associated with both mortality and differences between high (<40mL/cm H2O) and low (<40mL/cm H2O) compliance were analysed. Results: A total of 102 patients with COVID-19 who required invasive mechanical ventilation were analysed; 15 (14.7%) did not survive. Non-survivors were older (median 70 years, interquartile range [IQR] 67–75 versus median 61 years, IQR 52–66; P<0.01), and required a longer duration of ventilation (26 days, IQR 12–27 vs 8 days, IQR 5–15; P<0.01) and intensive care unit support (26 days, IQR 11–30 vs 11.5 days, IQR 7–17.3; P=0.01), with a higher incidence of acute kidney injury (15 patients [100%] vs 40 patients [46%]; P<0.01). There were 67 patients who had lung compliance data; 24 (35.8%) were classified as having high compliance and 43 (64.2%) as having low compliance. Mortality was higher in patients with high compliance (33.3% vs 11.6%; P=0.03), and was associated with a drop in compliance at day 7 (-9.3mL/cm H2O (IQR -4.5 to -15.4) vs 0.2mL/cm H2O (4.7 to -5.2) P=0.04). Conclusion: COVID-19 ARDS patients with higher compliance on the day of intubation and a longitudinal decrease over time had a higher risk of death.

Abstract Background Duration of invasive mechanical ventilation (IMV) prior to extracorporeal membrane oxygenation (ECMO) affects outcome in acute respiratory distress syndrome (ARDS). In coronavirus disease 2019 (COVID-19) related ARDS, the role of pre-ECMO IMV duration is unclear. This single-centre, retrospective study included critically ill adults treated with ECMO due to severe COVID-19-related ARDS between 01/2020 and 05/2021. The primary objective was to determine whether duration of IMV prior to ECMO cannulation influenced ICU mortality. Results During the study period, 101 patients (mean age 56 [SD ± 10] years; 70 [69%] men; median RESP score 2 [IQR 1–4]) were treated with ECMO for COVID-19. Sixty patients (59%) survived to ICU discharge. Median ICU length of stay was 31 [IQR 20.7–51] days, median ECMO duration was 16.4 [IQR 8.7–27.7] days, and median time from intubation to ECMO start was 7.7 [IQR 3.6–12.5] days. Fifty-three (52%) patients had a pre-ECMO IMV duration of > 7 days. Pre-ECMO IMV duration had no effect on survival (p = 0.95). No significant difference in survival was found when patients with a pre-ECMO IMV duration of < 7 days (< 10 days) were compared to ≥ 7 days (≥ 10 days) (p = 0.59 and p = 1.0). Conclusions The role of prolonged pre-ECMO IMV duration as a contraindication for ECMO in patients with COVID-19-related ARDS should be scrutinised. Evaluation for ECMO should be assessed on an individual and patient-centred basis.
