Abstract:
Objective To investigate the diagnosis and disease assessment of serum pancreatic stone protein(PSP/reg) in ventilator-associated pneumonia(VAP) by a prospective study.Methods The blood sample was collected in patients with mechanical ventilation(MV) from September 2012 to October 2015.Then the concentration of PSP/reg was detected by ELISA method and the time of MV and the outcome of VAP were recorded,while the patients who did not have VAP occurred in the same period regarded as control group.Results Compared with the control group,there was no significant difference in the serum concentration of PSP/reg in VAP group(P>0.05).From continuous monitoring,compared with the start time of MV,there was a significant increase in the concentration of PSP/reg in VAP group(P<0.05),and reached the highest peak in the fourth day.That of the seventh day was significantly decreased,but still higher than the first day(P<0.05).It decreased further in the fourteenth day,but compared to the start time of MV was still higher(P<0.05).In this study,38 cases were successfully evacuated in VAP group.Compared with the fourth day,the concentration of PSP/reg in the 38 cases in the stop of MV had significantly decreased(P<0.05),close to that of in the start of MV,but still a difference between them(P<0.05),and higher than that of the control group in the stop of MV(P<0.05).By Spearman analysis,we found that PSP/reg concentration in the first day had a significant correlation with CRP(r=0.570,P<0.05),but WBC and PCT were not(P>0.05).Conclusion PSP/reg can be used as one of the indicators for diagnosis of VAP,and may be related to the severity of VAP.
