Abstract:
Objective To detect peripheral blood neutrophil CD64 and procalcitonin(PCT)in children with diarrhea ,and to ex‐plore significance for differential diagnosis of diarrhea in children .Methods A total of 180 cases of children with diarrhea treated in this hospital from July 2012 to May 2014 were selected as subjects ,and were classified into three groups :bacterial diarrhea group (n=60) ,viral diarrhea group(n=60)and non infectious diarrhea group(n=60) .The levels of peripheral blood neutrophil CD64 and PCT were determined in all three groups ,and the diagnostic values of CD64 index and PCT were evaluated .Results The peripheral blood neutrophil CD64 index and level of PCT in the bacterial diarrhea group were significantly higher than those in the viral diar‐rhea group and non infectious diarrhea group ,and the positive rates of CD64 index and PCT in the bacterial diarrhea group were sig‐nificantly higher than those in the viral diarrhea group and non infectious diarrhea group ,all had statistically significant differences (P<0 .05) .The specificity and positive predictive value of CD 64 index in diagnosing bacterial diarrhea were significantly higher than those of PCT ,both had statistically significant differences (P<0 .05) .The relative analysis showed that the CD64 index was positively correlated with level of PCT (r=0 .865 ,P<0 .05) .Conclusion The CD64 index and PCT level of children with bacterial diarrhea increase significantly ,which indicates that the detection of CD64 index and PCT have significant clinical value in early diag‐nosis of bacterial diarrhea .
