摘 要:AIM To evaluate the diagnostic and prognostic value of presepsin in cirrhosis-associated bacterial infections. METHODS Two hundred and sixteen patients with cirrhosis were enrolled. At admission, the presence of bacterial infections and level of plasma presepsin, serum C-reactive protein(CRP) and procalcitonin(PCT) were evaluated. Patients were followed for three months to assess the possible association between presepsin level and short-term *** Present 34.7 of patients had bacterial infection. Presepsin levels were significantly higher in patients with infection than without(median, 1002 pg/m L vs 477 pg/m L, P 1206 pg/m L sensitivity, specificity, positive predictive values and negative predictive values were as follows: 87.5%, 74.5%, 61.8% and 92.7%. The accuracy of presepsin, however, decreased in advanced stage of the disease or in the presence of renal failure, most probably because of the significantly elevated presepsin levels in non-infected patients. 28-d mortality rate was higher among patients with 1277 pg/m L compared to those with ≤ 1277 pg/m L(46.9% vs 11.6%, P 0.001). In a binary logistic regression analysis, however, only PCT(OR = 1.81, 95%CI: 1.09-3.01, P = 0.022) but neither presepsin nor CRP were independent risk factor for 28-d mortality after adjusting with MELD score and leukocyte *** Presepsin is a valuable new biomarker for defining severe infections in cirrhosis, proving same efficacy as PCT. However, it is not a useful marker of short-term mortality.
