Abstract:
Objective To investigate the value of cysteine-rich secretory protein LCCL domain-containing 2 (CRISPLD2) in diagnosis and prognosis in patients with sepsis.Methods Clinical data of patients admitted to intensive care unit (ICU) of the First Hospital of Hebei Medical University from December 2014 to December 2016 were retrospectively analyzed. According to the severity of sepsis, the patients were divided into three groups: sepsis patients, severe sepsis patients and septic shock patients, and 100 healthy persons were enrolled as control group. Levels of serum CRISPLD2, procalcitonin (PCT) and C-reactive protein (CRP), acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score, and 28-day prognosis were recorded. Analysis of the correlation between CRISPLD2 and PCT, CRP, APACHEⅡscore, SOFA score was done. The receiver operating characteristic (ROC) curve was plotted for the CRISPLD2 value for the diagnosis and prognosis in patients with sepsis.Results A total of 115 patients with sepsis were enrolled in this study, including 52 sepsis, 48 severe sepsis, and 15 septic shock; 29 patients died after 28 days, 28-days mortality rate was 25.2%. There was no significant difference in CRISPLD2 between sepsis and healthy control group (mg/L: 204.1±74.5 vs. 211.3±12.0, P > 0.05); the level of CRISPLD2 in septic shock group was significantly lower than that in sepsis group and severe sepsis group (mg/L: 139.0±55.0 vs. 240.2±89.6, 233.0±8.9, bothP < 0.05). The level of PCT, CRP and APACHE Ⅱ score, SOFA score in sepsis patients were significantly higher than those in healthy control group, and increased with the severity of sepsis. There was no statistically significant difference in CRISPLD2 level between the dead and the survival of sepsis, and the levels of PCT and CRP in death group were significantly higher. The levels of CRISPLD2 were significantly negative correlated with the levels of PCT, CRP, APACHE Ⅱ score and SOFA score (r values were -0.089,-0.431, -0.115, -0.201, respectively, allP < 0.05). It was shown by ROC curve analysis that the area under ROC curve (AUC) and 95% confidence interval (95%CI) of CRISPLD2, PCT, CRP for diagnosis of sepsis were 0.907 (0.871-0.944), 0.922 (0.886-0.958), 0.916 (0.878-0.954) respectively, allP = 0.000; when the cut-off value of CRISPLD2 > 216.0 mg/L, the sensitivity was 96.7%, and the specificity was 92.6%, which power lied between PCT and CRP. The AUC of CRISPLD2 for prognosis was significantly lower than that of PCT [0.617 (0.507-0.727) vs. 0.786 (0.668-0.903),P <0.01]; when the cut-off value of CRISPLD2 was 103.5 mg/L, the sensitivity was 100%, and the specificity was 25.6%. Conclusion CRISPLD2 is a potential biomarker in sepsis, but cannot predict the prognosis of patients with sepsis.
