Introduction: Our understanding of the COVID-19 disease has been steadily evolving since the original outbreak in December 2019. Advanced disease is characterised by a hyperin ammatory state, systemic coagulopathies and multiorgan involvement, in particular respiratory distress.We here describe our initial experience with treating of COVID-19 patients based on early initiation of extracorporeal blood puri cation, systemic heparinisation and respiratory support.Methods: 15 patients were included; 2 were females. We monitored real-time several biochemical, immunological and coagulation biomarkers associated with disease severity following admission to our dedicated COVID-19 intensive care unit. To guide personalised treatment, we monitored among others levels of IL-6, IL-8, TNF-α, C-Reactive Protein (CRP), Neutrophil-to-Lymphocyte ratios, Thrombocyte counts, D-Dimers, Fibrinogen, and Activation Clotting time (ACT).Treatment consisted of individualised respiratory support supplemented with 1 -4 cycles of 24-hour Extracorporeal Organ Support (ECOS) and Blood Puri cation using the AN69ST (oXiris ® ) hemo lter. We administered heparin (300 U/kg) to counter suspected hypercoagulability (= elevated Fibrinogen or Ddimers) states to maintain ACT ≥ 180 seconds.Results: N = 10 presented with severe to critical disease (= dyspnoea, hypoxia, respiratory rate > 30/min, peripheral oxygen saturation < 90%, or > 50% lung involvement on X-ray imaging). A single case was admitted with a critical condition (= respiratory failure). One patient died after 5 days of hospitalisation after developing Acute Respiratory Syndrome. 8 Patients have been discharged -average ICU length-ofstay was 9.9 ± 2.4 days. Clinical improvement was associated with normalisation (increase) of thrombocytes, white blood cells, stable levels of IL-6 (< 50 ng/mL) and a decrease of CRP and Fibrinogen. Conclusion:Means to monitor COVID-19 disease severity during hospitalisation are crucial to control disease progression and prevent hyperin ammation and irreversible multiorgan failure. We present here a real-time monitoring system accounting for biochemical, immunological, coagulation parameters and radiological imaging.The combination of systemic heparin anticoagulation regimens and blood puri cation may prevent hyperin ammation, thromboembolism during hospitalisation and thus support clinical recovery.

Background: We describe a combinatorial intensive care approach and discuss the critical factors that allowed us to successfully manage a life-threatening case of acute anaerobic septic shock triggered by descending necrotizing mediastinitis. Case presentation: We admitted a 38-year-old critically ill Kosovar Albanian man to our intensive care unit because of clinical manifestations of severe sepsis. His condition had worsened in the previous 2 weeks following unsuccessful antibiotic therapy for tonsillitis complicated by retropharyngeal abscesses. Computed tomography and intraoperative observations identified abscesses in the anterior and middle mediastinum regions and the distal part of the neck, directly on the border with the left lobe of the thyroid gland. Cultures indicated infections with α-hemolytic Streptococcus and Clostridium species: High procalcitonin and lactate levels, blood gas analysis, poor peripheral capillary oxygen saturation, and severe hemodynamic instability pointed to a case of acute septic shock. The entire treatment consisted of an aggressive antibiotic regimen, transthoracic and mediastinal surgical evacuation of the abscess, vacuum sealing drainage with a pleural chest tube, continuous venovenous hemodiafiltration using cytokine-adsorbing hemofilters, and extracorporeal blood hyperoxygenation. Conclusions: Efficient treatment of severe anaerobic sepsis resulting from descending necrotizing mediastinitis should build on a multidisciplinary approach. In support of first-line therapies with targeted antibiotics and surgical debridement, clinicians should consider alternative therapies such as continuous venovenous hemodiafiltration with cytokine-adsorbing hemofilters and hyperoxygenation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
