Interdisziplinäres COVID-Board bei SARS-CoV-2-getriggerter hyperferritinämischer Inflammation

BACKGROUND: Patients with severe COVID-19 develop hyperferritinemic inflammation, a rare sepsis-like immune dysregulation syndrome. METHODS: Stratified treatment decisions in a cross-location telemedical interdisciplinary case conference were assessed in this retrospective cohort study. A standardized treatment algorithm including continuous positive airway pressure and noninvasive ventilation was implemented. A locally developed COVID inflammation score (CIS) defined patients at risk for severe disease. Patients with life-threatening inflammation were offered off-label treatment with the immune modulator ruxolitinib. RESULTS: Between 4 March 2020 and 26 June 2020 COVID-19 patients (n = 196) were treated. Median patient age (70 years) and comorbidity were high in interstudy comparison. Mortality in all patients was 17.3%. However, advance care planning statements and physician directives limited treatment intensity in 50% of the deceased patients. CIS monitoring of ruxolitinib-treated high-risk patients (n = 20) on days 5, 7, and15 resulted in suppression of inflammation by 42% (15–70), 54% (15–77) and 60% (15–80). Here, mortality was 20% (4/20). Adjusted for patients with a maximum care directive including ICU, total mortality was 8.7% (17/196). CONCLUSION: Severe COVID-19 pneumonia with hyperferritinemic inflammation is related to macrophage activation syndrome-like sepsis. An interdisciplinary intensive care teleconference as a quality tool for ICUs is proposed to detect patients with rare sepsis-like syndromes.
