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.

Megjegyzések:	To determine the prevalence of a new set of anti-glycan and anti-outer membrane protein (anti-OMP) antibodies in a Hungarian cohort of adult Celiac disease (CD) patients. METHODS: 190 consecutive CD patients [M/F: 71/119, age:39.9 (SD:14.1) years], 100 healthy, and 48 gastrointestinal controls were tested for glycan anti-Saccharomyces cerevisiae (gASCA), anti-laminaribioside (ALCA), anti-chitobioside, anti-mannobioside, anti-OMP antibodies and major NOD2/CARD15 mutations. Thirty out of 82 CD patients enrolled at the time of diagnosis were re-evaluated for the same antibodies after longstanding gluten-free diet (GFD). RESULTS: 65.9% of the CD patients were positive for at least one of the tested antibodies at the time of the diagnosis. Except anti-OMP and ALCA, anti-microbial antibodies were exclusively seen in untreated CD; however, the overall sensitivity was low. Any glycan positivity (LR+: 3.13; 95% CI: 2.08-4.73) was associated with an increased likelihood ratio for diagnosing CD. Significant correlation was found between the levels of anti-glycan and anti-endomysial or anti-transglutaminase antibodies. Anti-glycan positivity was lost after longstanding GFD. Anti-glycan antibody titers were associated with symptoms at presentation, but not the presence of NOD2/CARD15 mutations. Patients with severe malabsorption more frequently had multiple antibodies at diagnosis (P = 0.019). CONCLUSION: The presence of anti-glycan antibodies in CD seems to be secondary to the impaired small bowel mucosa which can lead to increased antigen presentation. Furthermore, anti-glycan positivity may be considered an additional marker of CD and dietary adherence.
