Megjegyzések:	AIM: Bacterial infections are frequent complications in cirrhosis with significant mortality. Early laboratory diagnosis is essential but challenging. We aimed to evaluate the diagnostic and prognostic value of presepsin in cirrhosis associated bacterial infections. METHODS: 216 patients with cirrhosis were enrolled. At admission, presence of bacterial infections and level of plasma presepsin, serum CRP and PCT were evaluated. Patients were followed for three months to assess the possible association between presepsin level and short-term mortality. RESULTS: 34.7% of patients had bacterial infection. Presepsin levels were significantly higher in patients with infection than without (median, 1002 vs. 477 pg/mL, p<0.001), increasing with the severity of infection (organ failure[OF]Yes vs. No: 2358 vs. 710 pg/mL, p<0.001). Diagnostic accuracy of presepsin for severe infections was similar to PCT and superior to CRP (AUC-ROC: 0.85, 0.85 and 0.66, respectively, p=NS for presepsin vs. PCT and p<0.01 for presepsin vs. CRP). At the optimal cut-off value of presepsin>1206 pg/mL sensitivity, specificity, PPV and NPV 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-day mortality rate was higher among patients with >1277 pg/mL compared to those with ?1277 pg/mL (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 and nor CRP were independent risk factor for 28-day mortality after adjusting with MELD score and leukocyte count.CONCLUSION: 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.

Cím:	Serological biomarkers for management of primary sclerosing cholangitis / Tornai Dávid, Vén Péter László, Lakatos Péter László, Papp Mária

Megjegyzések:	Clinical manifestations and progression of primary sclerosing cholangitis (PSC) are heterogeneous, and its pathogenesis is poorly understood. The importance of gut-liver interactions in the pathogenesis has been clinically confirmed and highlighted in different theories. Recent advances regarding biomarkers of biliarygut crosstalk may help to identify clinically relevant PSC subgroups assisting everyday clinical work-up (e.g., diagnosis, disease stratification, or surveillance) and the exploration of potential therapeutic targets. Alkaline phosphatase produced by the biliary epithelium is consistently associated with prognosis. However, its level shows natural fluctuation limiting its use in individual patients. Inflammatory, cell activation, and tissue remodeling markers have been reported to predict clinical outcome. Elevated immunoglobulin (Ig) G4 level is associated with a shorter transplantation-free survival. IgG type atypical perinuclear anti-neutrophil cytoplasmic antibodies (P-ANCAs) are non-specific markers of various autoimmune liver diseases and may reflect an abnormal B-cell response to gut microbial antigens. IgG type atypical P-ANCA identifies PSC patients with particular clinical and genetic (for human leukocyte antigens) characteristics. The presence of IgA type anti-F-actin antibody (AAA) may predict a progressive disease course, and it is associated with enhanced mucosal immune response to various microbial antigens and enterocyte damage. IgA type anti-glycoprotein 2 (GP2) antibodies identify patients with a severe disease phenotype and poor survival due to enhanced fibrogenesis or development of cholangiocarcinoma. Elevated soluble vascular adhesion protein-1 (sVAP-1) level is associated with adverse disease outcomes in PSC. High sVAP-1 levels correlate with mucosal addressin cell adhesion molecule-1 (MAdCAM-1) expression in the liver that contributes to gut activated T-cell homing to the hepatobiliary tract. In the present paper, we review the evidence on these possible serological markers that could potentially help address the unmet clinical needs in PSC.
