Abstract:
Objective To observe the changes of neutrophil CD64 (nCD64) index and serum procalcitonin (PCT) in hemodialysis patients with bacterial pneumonia,and to evaluate the effect of these two indicators in the course of diagnosis and treatment.Methods Fifty-three cases of bacterial pneumonia undergoing hemodialysis were enrolled in this study from November 2012 to November 2016 (infection group).At the same time,56 patients undergoing hemodialysis without bacterial infection (noninfection group) and fifty volunteers (control group) were also enrolled.The infection pathogen distribution,changes of nCD64 index and serum PCT in three groups were analyzed.And the changes of nCD64 index and serun.PCT before and after treatment in the infection group were analyzed too.Results Totally 53 strains of pathogens in the infection group were isolated,including 36 strains of gram-positive bacteria (accounting for 67.92％) and 17 strains of gram-negative bacteria (accounting for 32.08％).The nCD64 index of infection group,non-infection group and control group were as following:4.13 ± 0.43,0.82 ± 0.08 and 0.78 ± 0.08,and the serum PCT levels of infection group,non-infection group and control group were as following:(3.64 ± 0.29),(0.45 ± 0.04) and (0.45-± 0.04) μg/L.There were significant differences (P ＜ 0.01).The nCD64 index before and after treatment of infection group were 4.13 ± 0.43 and 0.86 ± 0.09.And serum PCT level before and after treatment of infection group were (3.64 ± 0.29) and (0.74 ± 0.07) μg/L.There were significant differences (P＜0.01).Conclusions The nCD64 index and serum PCT are sensitive indicators to determine the happening of bacterial pneumonia in patients undergoing hemodialysis,and it provides critical evidence for the evaluation of treatment in patients.
