Objective: Investigate the expression and significance of eosinophils in brucellosis.
Methods: Retrospective analysis of clinical data for 151 brucellosis patients (BR group), complete blood count and blood bacterial culture etc.; in addition, 150 general bacterial infection patients (BI group) and 135 persons in healthy physical condition upon testing (NC group) are selected respectively as the control groups to comparatively study expression of white blood cells and eosinophils for brucellosis patients. Adopt t test to compare measurement data.
Results: In comparison with BI group, WBC, NE, EO, MO, NE% and EO% in BR group are reduced but LY, LY% and MO% are increased and such difference shows statistical significance (P<0.01). In comparison with NC group, difference of WBC and NE in BR group shows no statistical significance (P>0.05). NE%, EO and EO% are reduced but MO, LY% and MO% are increased and such difference shows statistical significance (P<0.01). LY is increased and the difference shows statistical significance (P<0.05). White blood cell count is normal or is reduced among most of Brucellosis patients, accounting for 90.73% (137/151); the patients whose eosinophils are reduced account for 75.50% (114/151) and those whose eosinophils disappear are about 18.54% (28/151).
Conclusion: There is an incidence rate of eosinophils decrease or disappearance in Brucellosis and it shows the indication significance in the diagnosis of early disease.
