Lactate levels and lactate clearance are known predictors of outcome in critically ill patients in the intensive care unit (ICU). The prognostic value of lactate is not well established in liver cirrhosis and acute‐on‐chronic liver failure (ACLF). The aim of this study was to assess the prognostic value of lactate levels and clearance in critically ill patients with cirrhosis. Patients with cirrhosis admitted to the ICU were studied at the University Medical Center Hamburg‐Eppendorf (n = 566, derivation cohort) and the Medical University of Vienna and the University Hospitals Leuven (n = 250, validation cohort). Arterial lactate was measured on admission and during the first 24 hours. Patients were followed for 1 year and outcome was assessed. Admission lactate was directly related to the number of organs failing and to 28‐day mortality (area under receiver operating characteristic [AUROC] 0.72; P < 0.001). This also applied to lactate follow‐up measurements after 6, 12, and 24 hours (P < 0.001 for all, AUROC > 0.70 for all). Lactate clearance had significant predictive ability for 28‐day mortality in patients with elevated serum lactate ≥5 mmol/L. Admission lactate and 12‐hour lactate clearance (in patients with admission lactate ≥5 mmol/L), respectively, were identified as significant predictors of 1‐year mortality, independent of Chronic Liver Failure Consortium acute‐on‐chronic liver failure score (CLIF‐C ACLFs). A lactate‐adjusted CLIF‐C ACLFs was developed (CLIF‐C ACLFsLact), which performed significantly better than the original CLIF‐C ACLFs in prediction of 28‐day mortality in the derivation and validation cohort. Conclusion: Lactate levels appropriately reflect severity of disease and organ failure and were independently associated with short‐term mortality in critically ill patients with liver cirrhosis. Lactate is a simple but accurate prognostic marker, and its incorporation improved performance of CLIF‐C ACLFs significantly.

Sudden cardiac arrest (CA) is one of the leading causes of death in adults in many parts of the world [1]. Every year estimated 350.000 to 700.000 people in Europe are suffering CA and receive cardiopulmonary resuscitation (CPR) [2]. To date, there is no data available on CA and CPR in patients with liver cirrhosis.

Einleitung: Veranderungen der Hamostase finden sich haufig bei Patienten mit Leberzirrhose. Der „disseminated intravascular coagulation score“ (DIC score) errechnet sich aus Routine-Gerinnungsparametern (Thrombozytenzahl, D-Dimere, Fibrinogen und Prothrombinzeit/-index) und ist ein bekannter Uberlebenspradiktor bei kritisch kranken Patienten. Aufgrund der Haufigkeit von „pathologischen“ Gerinnungsparametern bei Patienten mit Leberzirrhose ist bislang jedoch unklar, ob der DIC score eine prognostische Aussagekraft bei diesen Patienten besitzt. Ziele: Ziel dieser Studie ist die Bestimmung und die Beurteilung der Anwendbarkeit des DIC Score bei kritisch kranken Patienten mit Leberzirrhose. Methodik: Zirrhose-Patienten, die an der Intensivstation zur Aufnahme gelangten, wurden in dieser Arbeit analysiert. Detaillierte Laboruntersuchungen inklusive Gerinnungsanalysen wurden bei Aufnahme durchgefuhrt und der DIC Score berechnet. Das 28-Tage-Uberleben der Patienten wurde erhoben. Ergebnis: Hundertfunfzig Intensivstations-Aufnahmen mit Leberzirrhose wurden analysiert. Neununddreisig Prozent waren weiblich. Das mediane Alter betrug 56 (IQR 49 – 63) Jahre. Der mediane SOFA Score bei Aufnahme betrug 9 (6 – 13), der mediane MELD score 26 (IQR 18 – 36). Die 28-Tage-Mortalitat lag bei 59%. Der mediane DIC score bei Aufnahme betrug 5 (IQR 4 – 6). „Overt DIC“ (DIC Score ≥5) fand sich bei 65% der Aufnahmen. Bezogen auf die 28-Tage-Mortalitat war der DIC Score bei Nicht-Uberlebenden signifikant hoher als bei Uberlebenden (5 (IQR 4 – 7) vs. 4 (IQR 3 – 6); p < 0.01). Die AUROC fur den DIC Score hinsichtlich der Vorhersage der 28-Tage-Mortalitat war 0.68 (95% CI 0.59 – 0.77). Das Vorhandensein einer „Overt DIC“ bei Aufnahme war signifikant mit der 28-Tage-Mortalitat assoziiert (OR = 3.4 (95% CI 1.69 – 6.84), p < 0.01). Die 28-Tage-Mortalitatsrate bei Aufnahmen mit Zirrhose und „Overt DIC“ betrug 70% verglichen zu 40% bei Patienten mit einem DIC score < 5. Schlussfolgerung: Veranderungen der Hamostase finden sich in der Mehrzahl der Patienten mit Leberzirrhose auf der Intensivstation. Der DIC score ist ein Pradiktor fur das 28-Tage-Uberleben bei kritisch kranken Patienten mit Leberzirrhose.

The disseminated intravascular coagulation (DIC) score is a predictor of outcome in critically ill patients [1]. Yet, disturbances of coagulation are a common finding in patients with liver cirrhosis. Thus, the prognostic value of the DIC score and its subcomponents in patients with liver cirrhosis is unclear.

Hypoxic hepatitis (HH) is a frequent cause of acute hepatocellular damage in critically ill patients associated with high mortality. Indocyanine green, a medical dye, is removed solely by the liver without entering enterohepatic circulation. Therefore its plasma disappearance rate (ICG-PDR) is an effective clinical tool for assessment of liver function in acute and chronic hepatic disease.

Clostridium species are gram-positive, anaerobic, spore-forming bacteria and some species have pathogenic nature. There is limited data regarding Clostridium non-difficile infection in critically ill patients available. Symptoms of infection are often non-specific, which leads to delayed diagnosis and therapy initiation in these patients.
