Value of HBP in diagnosis of catheter-related infections in maintenance hemodialysis patients / 国际检验医学杂志

ABSTRACT

Objective To investigate the diagnostic value of Heparin-binding protein (HBP) in maintenance hemodialysis patients in catheter-related infections.Methods 75 patients with maintenance hemodialysis were enrolled in the study and divided into observation group(n=45,with catheter-related infections) and control group(n=45,without catheter-related infections).The serum HBP,procalcitonin (PCT) and C-reactive protein (CRP) levels were detected.The values in diagnostic of catheter-related infections and Gram-negative bacterial infections were analyzed by receiver operating characteristic(ROC) curve.Results There were 34 cases of patients infected by Gram-positive bacterial with the rate of 75.6% and 11 cases of patients infected by Gram-negative bacterial with rate of 24.4%.The serum HBP,PCT and CRP levels in observation group were significantly higher than those in control group and the serum HBP,PCT levels of patients infected by Gram-negative bacterial were higher than those of patients infected by Gram-positive bacterial (P27.52 μg/L with sensitivity of 100.0% and specificity of 61.8%.Conclusion Serum HBP,PCT and CRP may be the effective indicators for diagnosis of catheter-related infections,and the HBP has important reference value for diagnosis of Gram-negative bacterial infections.
