title: High C-reactive protein and low cholesterol levels are prognostic markers of survival in severe sepsis.
abstract: OBJECTIVE
  To evaluate serum C-reactive protein and cholesterol as a prognostic factor for survival in patients with severe sepsis.
  
  
  METHODS
  Prospective study.
  
  
  METHODS
  University hospital.
  
  
  METHODS
  The study population consisted of 96 patients (age range, 18-75 years; median, 56 years; men/women ratio, 40:56) in whom severe sepsis was diagnosed.
  
  
  METHODS
  Patients' serum levels of C-reactive protein and cholesterol were measured upon admission to an intensive care unit, two days later, and on the day of discharge from the intensive care unit or on the day of death.
  
  
  RESULTS
  Cholesterol levels were significantly lower among the nonsurviving patients (day 1, 92.2 +/- 25.1 mg/dL; day 2, 92.1 +/- 21.7 mg/dL; death/discharge day, 92.2 +/- 21.7 mg/dL) than surviving patients (day 1, 175.1 +/- 38.6 mg/dL [P < 0.001]; day 2, 173.0 +/- 39.3 mg/dL [P < 0.001]; death/discharge day, 171.8 +/- 39.6 mg/dL [P = 0.010]). Median C-reactive protein levels were significantly higher among the nonsurvivors (day 1, 32 mg/dL [range, 20.5-64.5 mg/dL]; day 2, 33 mg/dL [range, 22-74.5 mg/dL]; death/discharge day, 30 mg/dL [range, 22-57 mg/dL]) than survivors (day 1, 10 mg/dL [range, 6-14 mg/dL]; day 2, 9 mg/dL [range, 5-10 mg/dL]; death/discharge day, 6 mg/dL [range, 3-9 mg/dL]; P < 0.001).
  
  
  CONCLUSIONS
  Serum C-reactive protein and cholesterol are a predictor of survival in patients with severe sepsis. Low cholesterol and high C-reactive protein levels appear as a valuable tool for individual risk assessment in severe sepsis patients and for stratification of high-risk patients in future intervention trials.
