title: Procalcitonin-a new diagnostic tool in complications following liver transplantation.
abstract: OBJECTIVE
  Does procalcitonin (PCT) allow differentiation between infection and rejection following liver transplantation in the case of fever of unknown origin (FUO)?
  
  
  METHODS
  Open prospective trial.
  
  
  METHODS
  transplant intensive care unit at a university hospital.
  
  
  METHODS
  Forty patients after liver transplantation.
  
  
  METHODS
  Liver biopsy for diagnosis of rejection, transcutaneous aspiration cytology for monitoring of lymphocyte activation.
  
  
  METHODS
  Procalcitonin from EDTA plasma, APACHE II, Sepsis, score (Elbute and Stoner).
  
  
  RESULTS
  Eleven patients suffered an infectious complication resulting in an increase in PCT levels (2.2-41.7 ng/ml). Eleven patients developed a rejection episode; none of these patients showed a rise in PCT levels. The statistical difference between PCT levels in rejection and infection was significant (p<0.05) on the day of diagnosis.
  
  
  CONCLUSIONS
  PCT allows differentiation between rejection and infection in the case of FUO. Elevation of PCT plasma levels develops early postoperatively due to operation trauma, and, in the case of FUO with no rise in PCT, a rejection may be suspected.
