Abstract: Objective To investigate the value of heparin binding protein(HBP) in assessing the condition and prognosis of elderly patients with infectious diseases. Methods From August 2018 to December 2020, 168 elderly patients in the Emergency Department of our hospital were selected. According to the presence of infection and organ failure, they were divided into in the sepsis group (group A, n=81), the mild infection group (group B, n=48) and the non-infection group (group C, n=39). The levels of HBP, procalcitonin(PCT), C-reaction protein(CRP), white blood cell count (WBC) and the highest body temperature were collected within 24 h after admission, and sequential organ failure score was assessed. Receiver operating characteristic (ROC) curve was established to evaluate the prognostic significance of each index, and Youden index was calculated to determine the best cut-off value. Results The levels of HBP, PCT and CRP in group A were significantly higher than those in group B and group C (P<0.05). The levels of HBP, CRP and WBC in group B were higher than those in group C (P<0.05). There was no significant difference in the level of PCT between group B and group C (P>0.05). The highest 24 h body temperature in group A was significantly higher than that in group B and group C (P<0.001). In predicting the risk of death of all selected patients, the areas under the ROC curve (AUC) of HBP, PCT and CRP were 0.802, 0.777 and 0.711, respectively. In predicting the risk of death in sepsis patients, the AUC of HBP and PCT were 0.724 and 0.648, respectively. Conclusions HBP can be used as an effective biomarker to evaluate the condition and prognosis of infectious diseases in the elderly.
