Abstract:
Objective To detect the ascites CD64 index of patients with decompensated cirrhosis ,and explore the value in the di-agnosis of spontaneous bacterial peritonitis (SBP) .Methods Decompensated cirrhosis with ascites patients were divided into non-SBP group ,SBP suspected group and SBP diagnosed group .Two control groups were composed of patients with ascites culture pos-itive and non-SPB group .SBP suspected group were further grouped according to abdominal pain and the percentage of peripheral blood neutrophils .The CD64 index was detected by flow cytometry .Compared the difference of ascites CD64 index after treatment , and analyzed diagnosis performance of procalcitonin in human peripheral blood and ascites white blood cell count of SBP .Results The level of the ascites CD64 index was significantly higher in SBP diagnosed group (179 .39 ± 65 .56)and SBP suspected group (115 .49 ± 58 .42)than that of non-SBP group(26 .88 ± 26 .05)(P<0 .01) .The differences of the ascites CD64 index between SBP suspected associated with abdominal pain group and SBP suspected associated with painless group was not statistically significant (P>0 .05) .The level of the ascites CD64 index in SBP suspected with percentage of peripheral blood neutrophils elevated group was increased significantly than non-elevated group(P<0 .05) .CD64 index level in effective treatment group was significantly lower than the ineffective treatment group(P<0 .01) .The area of the ascites CD64 index under the curve was greater than procalcitonin in human peripheral blood and ascites WBC count ,and had a higher sensitivity and specificity .Conclusion The detection process of the ascites CD64 index is fast and with less influential factors ,which provides a new choice for the clinical diagnosis of SBP .
