Abstract:
Objective To study the role of heparin-binding protein (HBP) in sepsis-associated acute respiratory distress syndrome (ARDS),and to evaluate the prognostic value of HBP in ARDS.Method Sixty seven sepsis patients were enrolled in the prospective study.According to whether present ARDS,patients were divided into two groups:ARDS group and non-ARDS group.Blood samples were obtained within 2 hours after patients were diagnosed with sepsis.We measured the level of interleukin-6,interleukin8 and HBP by ELISA,counted the number of polymorphonuclear neutrophils (PMN),and calculated Acute Physiology and Chronic Health Evaluation Ⅱ score.We compared interleukin-6,interleukin-8,PMN and HBP between two groups by Student's t test.Correlation analysis was studied between HBP and other indicators by Spearman rank correlation coefficient.We also studied the early prognostic value on sepsisassociated ARDS by establishing receiver operating characteristic (ROC) curve.Results Interleukin-6 (t=4.25,P＜0.01),interleukin-8 (t=10.10,P＜0.01),PMN (t=3.47,P=0.0009) and HBP (t =0.0225,P =2.336,all showed significant difference between ARDS group and non-ARDS group.Interleukin-6 (r=0.535,P=0.002),interleukin-8 (r=0.419,P=0.017) and PMN (r=0.419,P =0.017) all had positive correlation with HBP.The area under curve (AUC) of HBP predicting ARDS was 0.796.Conclusions HBP level elevated in sepsis-associated ARDS patients and were correlated with interleuki-6,interleuki-8 and PMN.HBP show a high value on predicting emergence of sepsis-associated ARDS.HBP may play an important role in sepsis-associated ARDS pathological process.From this study we can conclude one of possible ARDS pathogenesis:inflammatory mediators,such as interleuki-6,interleuki8,activate PMN.Subseqoently PMN releases HBP.Then HBP resolts in vascolar leakage,which is one of the basic ARDS pathology.
