title: [Clinical value of CD64 expression in adults with measles complicating bacterial pneumonia].
abstract: OBJECTIVE
  To study the clinical value of expression of peripheral blood neutrophil CD64 in adults with measles complicating pneumonia.
  
  
  METHODS
  106 patients were divided into two groups by clinical manifestation and bacteria study: measles complicating bacterial pneumonia group and measles complicating viral pneumonia, using flow cytometry determination of CD64, C-reactive protein (CRP) and white blood cell (WBC) count.
  
  
  RESULTS
  The expression of CD64 in the bacterial pneumonia group with eruptive stage was (32.15 +/- 11.07) MFI, which was significantly higher than that in the group of with recovery stage (10.6 +/- 3.23) MFI (P < 0.01) and viral pneumonia (9.55 +/- 3.48) MFI (P < 0.01). These markers were considered positive if CD64 > or = 8.5 MFI, CRP > or = 10 mg/L and WBC > or = 9.05 x 10(9)/L. Their sensitivity was 78.12%, 80.48% and 59.37%. Their specificity was 76.19% ,67.67% and 64.28%. Their accuracy rate was 77.35%, 74.52%, 61.32%; CD64 has a positive relationship with CRP.
  
  
  CONCLUSIONS
  Compared to CRP, expression of peripheral blood neutrophil CD64 can be a better marker in the early diagnosis of patients with measles complicating bacterial pneumonia and as one of the indicators of disease conditions.
