title: [Comparison of an immature platelet fraction and reticulated platelet in liver cirrhosis].
abstract: BACKGROUND
  The main causes of thrombocytopenia in cirrhosis are thought to be platelet destruction and the reduction of thrombopoietin (TPO) expression in the liver. Immature platelet fraction (IPF) has been measured by a fully automated analyzer (Sysmex XE-2100, Japan) as reticulated platelet (RP), which is reflected with thrombopoiesis in bone marrow. In this study, we tried to compare the percentage of IPF (IPF) with that of RP (RP) in patients with liver cirrhosis (LC) and controls.
  
  
  METHODS
  We compared IPF to RP in 72 liver cirrhosis patients and 30 healthy normal controls. RP was stained with acridine orange, followed by FC500 (Beckman Coulter, USA) analysis and the IPF was identified by flow cytometry with the use of a nucleic acid specific dye in the reticulocyte channel on the Sysmex XE-2100 (TOA Medical Electronics Co., Ltd., Japan).
  
  
  RESULTS
  IPF value in the healthy control was 2.2% (1.7-5.2). RP and IPF were significantly higher in the patients with liver cirrhosis (P<0.05). IPF appeared to be correlated with RP (y=0.19x+3.35, r=0.34, P<0.05). In ROC for diagnosis of LC, IPF was significantly more useful than RP.
  
  
  CONCLUSIONS
  This results show that a rapid, inexpensive automated method for measuring the IPF is feasible and should become a standard parameter in evaluating reticulated platelets.
