Abstract | BACKGROUND: METHODS: Total and individual serum bile acids were assessed via high-performance liquid chromatography in 320 critically ill patients and 19 controls. RESULTS: Total serum bile acids were threefold higher in septic than cardiogenic shock patients and sixfold higher than in post-surgical patients or controls (p < 0.001). Elevated bile acid levels correlated with severity of illness, renal dysfunction and inflammation (p < 0.05). Total bile acids predicted 28-day mortality independently of sex, age, serum bilirubin and severity of illness (HR 1.041, 95% CI 1.013-1.071, p < 0.005). Best prediction of mortality of total bile acids was seen in patients suffering from septic shock. CONCLUSIONS: Individual and total BAs are elevated by various degrees in different shock conditions. BAs represent an early predictor of short-term survival in a mixed cohort of ICU patients and may serve as marker for early risk stratification in critically ill patients. Future studies should elucidate whether modulation of BA metabolism and signalling influences the clinical course and outcome in critically ill patients.
