Introduction: This study investigates the impact of sequential extracorporeal treatments with oXiris® or CytoSorb® plus Seraph-100® on the clinical and laboratory parameters of critically ill COVID-19 patients with bacterial superinfection. Methods: Patients admitted to the intensive care unit with COVID-19, bacterial superinfection, and undergoing blood purification (BP) were enrolled in this prospective, single-center, observational study. “standard BP” with oXiris® or CytoSorb® were used in 35 COVID-19 patients with bacterial infection. Seraph-100® was added in 33 patients when available serially in the same oXiris® circuit or as sequential treatment with CytoSorb® as a sequential BP. Results: A significant reduction in SOFA score 3 days after treatment was observed in patients undergoing sequential BP (11.3 vs. 8.17, p < 0.01) compared to those undergoing “standard BP” (11.0 vs. 10.3, p > 0.05). The difference between the observed and expected mortality rate based on APACHE IV was greater in the sequential BP group (42.4% vs. 81.7%, p < 0.001) than the “standard BP” (74.2% vs. 81.7%, p > 0.05). Patients treated with sequential BP had a longer survival than those treated with “standard BP” (22.4 vs. 18.7 months; p < 0.001). Conclusions: The sequential approach may enhance the positive effect of BP on organ dysfunction among critically ill patients with COVID-19 and bacterial superinfection.
Despite advances in medical therapy and mechanical circulatory support (MCS), heart transplant (HT) remains the gold standard therapy for end-stage heart failure. Patients in cardiogenic shock require prompt intervention to reverse hypoperfusion and end-organ damage. When medical therapy becomes insufficient, MCS should be considered. Historically, it has been reported that critically ill patients bridged with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) directly to HT have worse outcomes. However, when the heart allocation system gives the highest priority to patients on VA-ECMO support, those patients have a higher incidence of HT and a lower incidence of death or removal from the transplant list. Moreover, patients with a short waiting time on VA-ECMO have a similar hazard of mortality to non-ECMO patients. According to the reported data, bridging with VA-ECMO directly to HT may be a solution in the selection of critically ill patients when the anticipated waiting list time is short. However, when a prolonged waiting time is expected, more durable MCS should be considered. Regardless of the favorable results of the direct bridging to HT with ECMO in selected patients, the superiority of this strategy compared to the bridge-to-bridge strategy (ECMO to durable MCS) has not been established and further studies are mandatory in order to clarify this issue.

Background: Patients undergoing prolonged mechanical ventilation commonly require tracheotomy. The main aim of this study was to evaluate the outcomes of tracheotomy for patients with acute respiratory distress syndrome (ARDS) associated with COVID-19 in low-resource settings. Methods: A retrospective, single-center, observational cohort study was performed on patients with ARDS associated with COVID-19. Patients who underwent intubation alone were compared with those who received both intubation and subsequent tracheotomy. The analysis included patient demographics, comorbidities, and outcomes. Results: Patients undergoing tracheotomy (n = 89) were compared with intubated patients (n = 622). The median time from intubation to tracheotomy was 10 days (IQR: 6–15 days). Overall, 608 patients (85.5%) died in the hospital. Thirty-seven patients (35.9%) in the survival group had tracheostomy compared with fifty-two patients (8.5%) in the non-survival group (p < 0.001). The Kaplan–Meier curve shows a higher probability of survival in the tracheotomy group compared with the non-tracheotomy group (log-rank test: p < 0.001). Tracheotomy was found to be independently associated with lower in-hospital mortality (HR = 0.16 [95% CI: 0.11–0.23], p < 0.001) in the multivariable Cox proportional hazards regression analysis after adjusting for potential confounding factors. Furthermore, tracheotomy was associated with a higher cumulative incidence of being alive and off the ventilator at day 28 (SHR = 2.87 [95% CI: 1.88–4.38], p < 0.001). Conclusions: Tracheotomy was associated with reduced in-hospital mortality and longer ventilator-free days.
