FallberichtEin 20-jähriger adipöser Patient stellte sich im August 2018 in einer auswärtigen Klinik zur Septumplastik und Muschelverkleinerung bei Septumdeviation und Muschelhyperplasie ohne relevante Vorerkrankungen vor. Intraoperativ war keine Antibiotikagabe erfolgt. Postoperativ wurde der Patient zur weiteren Betreuung mit Doyle-Splinten und Gelaspon® auf die Normalstation verlegt. Es war Hochsommer und die Krankenzimmertemperatur bei ausgefallener Klimaanlage sehr hoch. Wie erst später fremdanamnestisch bekannt wurde, hatte der Patient eine bereits vor stationärer Aufnahme mehrere Tage bestehende, aber nicht mitgeteilte Enteritis. Am Morgen des ersten postoperativen Tages wies der Patient Zeichen der Sepsis auf: arterielle Hypotonie, Tachykardie, Tachypnoe und Desorientierung (= quick Sepsis – related organ failure assessment Score [qSOFA Score] = positiv). Es erfolgte die Gabe von Kristalloiden und bei Schwellung des Gesichtes die Entfernung der Doyle-Splinte. Ungeachtet dessen kam es zur progredienten Verschlechterung und Entwicklung eines schweren Schocks, so dass mit der Gabe von Vasopressoren begonnen wurde. Bei zusätzlich beginnender respiratorischer Erschöpfung wurde die Indikation zur Intubation gestellt. Während der Intubation kam es zur Aspiration. Zur weiteren intensivmedizinischen Versorgung erfolgte aus kapazitären Gründen die Verlegung auf die interdisziplinäre internistische Intensivstation unserer Klinik mit zunächst unklarem Infektfokus. Bei Übernahme war der Patient intubiert und beatmet (CPAP PEEP 9 mbar, Druckunterstützung 16 mbar, FiO2 0,8) und hoch katecholaminpflichtig (Noradrenalin 1 µg/kg/min, Epinephrin 0,2 µg/kg/min).

Objective This study aimed to identify the prognostic factors of patients with first-time acute myocardial infarction (AMI) and to establish a nomogram for prognostic modeling. Methods We studied 985 patients with first-time AMI using data from the Multi-parameter Intelligent Monitoring for Intensive Care database and extracted their demographic data. Cox proportional hazards regression was used to examine outcome-related variables. We also tested a new predictive model that includes the Sequential Organ Failure Assessment (SOFA) score and compared it with the SOFA-only model. Results An older age, higher SOFA score, and higher Acute Physiology III score were risk factors for the prognosis of AMI. The risk of further cardiovascular events was 1.54-fold higher in women than in men. Patients in the cardiac surgery intensive care unit had a better prognosis than those in the coronary heart disease intensive care unit. Pressurized drug use was a protective factor and the risk of further cardiovascular events was 1.36-fold higher in nonusers. Conclusion The prognosis of AMI is affected by age, the SOFA score, the Acute Physiology III score, sex, admission location, type of care unit, and vasopressin use. Our new predictive model for AMI has better performance than the SOFA model alone.

Porcine model of peritonitis-induced sepsis is a well-established clinically relevant model of human disease. Interindividual variability of the response often complicates the interpretation of findings. To better understand the biological basis of the disease variability, the progression of the disease was compared between animals with sepsis and septic shock. Peritonitis was induced by inoculation of autologous feces in fifteen anesthetized, mechanically ventilated and surgically instrumented pigs and continued for 24 h. Cardiovascular and biochemical parameters were collected at baseline (just before peritonitis induction), 12 h, 18 h and 24 h (end of the experiment) after induction of peritonitis. Analysis of multiple parameters revealed the earliest significant differences between sepsis and septic shock groups in the sequential organ failure assessment (SOFA) score, systemic vascular resistance, partial pressure of oxygen in mixed venous blood and body temperature. Other significant functional differences developed later in the course of the disease. The data indicate that SOFA score, hemodynamical parameters and body temperature discriminate early between sepsis and septic shock in a clinically relevant porcine model. Early pronounced alterations of these parameters may herald a progression of the disease toward irreversible septic shock.

Abstract Background The Infectious Diseases Society of America has identified the potential use of SARS-CoV-2 genomic load for prognostication purposes as a key research question. Methods We designed a retrospective cohort study that included adult patients with COVID-19 pneumonia who had at least 2 positive nasopharyngeal tests at least 24 hours apart to study the correlation between the change in the genomic load of SARS-CoV-2 in nasopharyngeal samples, as reflected by the Cycle threshold (Ct) value of the real-time Polymerase Chain Reaction (PCR) assay, with change in clinical status. The Sequential Organ Failure Assessment (SOFA) score was used as a surrogate for patients’ clinical status. A linear mixed-effects regression analysis was performed. Results Among 457 patients who presented to the emergency department between 3/31/2020- 4/10/2020, we identified 42 patients who met the inclusion criteria. The median initial SOFA score was 2 (IQR 2–3). 20 out of 42 patients had a lower SOFA score on their subsequent tests. We identified a statistically significant inverse correlation between the change in SOFA score and change in the Ct value with a decrease in SOFA score by 0.05 (SE 0.02; p < 0.05) for an increase in Ct values by 1. This correlation was independent of the duration of symptoms. Flow chart A graph of the Cycle Threshold (Ct) values of the of Cepheid Xpert® Xpress SARS-CoV-2 assay measured on repeat screening of the 42 included patients. Graph of the fitted SOFA scores based on the Cycle Threshold values per patient. Conclusion Our findings suggest that an increasing Ct value in sequential tests may be of prognostic value for patients diagnosed with COVID-19 pneumonia. Before repeat testing can be recommended routinely in clinical practice as a predictor of disease outcomes, prospective studies with a standardized interval between repeat tests should confirm our findings.
