Background: Acute respiratory distress syndrome (ARDS) is associated with high mortality rates. ARDS patients suffer from severe hypoxemia, and extracorporeal membrane oxygenation (ECMO) therapy may be necessary to ensure oxygenation. ARDS has various etiologies, including trauma, ischemia-reperfusion injury or infections of various origins, and the associated immunological responses may vary. To support the immunological response in this patient collective, we used intravenous IgM immunoglobulin therapy to enhance the likelihood of pulmonary recovery.
Methods: ARDS patients admitted to the intensive care unit (ICU) who were placed on ECMO and treated with (IVIG group; = 29) or without (control group; = 28) intravenous IgM-enriched immunoglobulins for 3 days in the initial stages of ARDS were analyzed retrospectively.
Results: The baseline characteristics did not differ between the groups, although the IVIG group showed a significantly reduced oxygenation index compared to the control group. We found no differences in the length of ICU stay or ventilation parameters. We did not find a significant difference between the groups for the extent of inflammation or for overall survival.
Conclusion: We conclude that administration of IgM-enriched immunoglobulins as an additional therapy did not have a beneficial effect in patients with severe ARDS requiring ECMO support.
Trial Registration: Clinical Trials: NCT02961166; retrospectively registered.

Introduction: Achalasia, a rare esophageal disorder with an annual incidence of 0.11 per 100,000 in children, is characterized by impaired lower esophageal sphincter (LES) relaxation and peristalsis. Infantile cases are extremely uncommon and often linked to genetic conditions like Allgrove and Down syndrome.

Background: Ultra-protective ventilation is the combination of low airway pressures and tidal volume (Vt) combined with extra corporeal carbon dioxide removal (ECCOR). A recent large study showed no benefit of ultra-protective ventilation compared to standard ventilation in ARDS (Acute Respiratory Distress Syndrome) patients. However, the reduction in Vt failed to achieve the objective of less than or equal to 3 ml/kg predicted body weight (PBW).

Background: We retrospectively analyzed the patients who underwent prone positioning (PP) for acute respiratory failure after pulmonary endarterectomy (PEA).
Methods: One hundred twenty five patients underwent PEA and the outcome related to patients who underwent PP for acute respiratory failure after surgery was analyzed.
Results: Thirteen patients (10%) underwent PP at the mean duration of 28.

Severe pneumonia (SP) is a common cause of septic shock and Acute Respiratory Distress Syndrome (ARDS), leading to multiorgan dysfunction syndrome. Patients with SP often require respiratory support, and SP is associated with high mortality and is a significant economic burden for hospitalized patients. Therefore, early identification and real-time monitoring of the severity of SP are crucial for improving outcomes.

BACKGROUND Acute respiratory distress syndrome (ARDS) due to coronavirus 2019 (COVID-19) can result in severe disease requiring mechanical ventilatory support. A subset of these patients, however, demonstrate refractory hypoxemia/hypercarbia requiring veno-venous extracorporeal membrane oxygenation (V-V ECMO) as adjunctive therapy. The primary goal of V-V ECMO is a "bridge" to recovery of native lung function; however, patients may progress to irreversible pulmonary damage requiring lung transplantation.
