RESUMO
BACKGROUND: Both iron overload and iron deficient anemia can associate with cirrhosis. At the same time, inflammation might be continuously present in cirrhotic patients due to bacterial translocation and patients' susceptibility to infections. Ferritin is a sensitive and widely available marker of iron homeostasis, in addition it acts as an acute phase protein. Therefore, we evaluated the prognostic potential of serum ferritin in the long-term follow-up of cirrhotic outpatients. METHODS: A cohort of 244 cirrhotic outpatients was recruited and followed for 2 years. We measured their serum ferritin levels in our routine laboratory unit at enrolment and investigated its association with clinical outcomes. RESULTS: Ferritin serum level was higher in males and older patients than in females (median: 152.6 vs. 75 µg/L, p < 0.001) or younger individuals (median: 142.9 vs. 67.9 µg/L, p = 0.002). Patients who previously survived variceal bleeding had lower ferritin levels (median: 43.1 vs. 146.6 µg/L, p < 0.001). In multivariate regression models, including laboratory and clinical factors, lower (< 40 µg/L) ferritin concentration was associated with the development of decompensated clinical stage in patients with previously compensated cirrhosis (sHR: 3.762, CI 1.616-8.760, p = 0.002), while higher (> 310 µg/L) circulating ferritin levels were associated with increased risks of bacterial infections in decompensated patients (sHR: 2.335, CI 1.193-4.568, p = 0.013) and mortality in the whole population (HR: 2.143, CI 1.174-3.910, p = 0.013). CONCLUSION: We demonstrated usefulness of serum ferritin as a prognostic biomarker in cirrhosis, pointing out that both low and high concentrations need attention in these patients.

BACKGROUND: Disturbance of consciousness (DOC) may develop in acute pancreatitis (AP). In clinical practice, it is known that DOC may worsen the patient's condition, but we have no exact data on how DOC affects the outcome of AP. METHODS: From the Hungarian Pancreatic Study Groups' AP registry, 1220 prospectively collected cases were analyzed, which contained exact data on DOC, included patients with confusion, delirium, convulsion, and alcohol withdrawal, answering a post hoc defined research question. Patients were separated to Non-DOC and DOC, whereas DOC was further divided into non-alcohol related DOC (Non-ALC DOC) and ALC DOC groups. For statistical analysis, independent sample t-test, Mann-Whitney, Chi-squared, or Fisher exact test were used. RESULTS: From the 1220 patients, 47 (3.9%) developed DOC, 23 (48.9%) cases were ALC DOC vs. 24 (51.1%) Non-ALC DOC. Analysis between the DOC and Non-DOC groups showed a higher incidence of severe AP (19.2% vs. 5.3%, p < 0.001), higher mortality (14.9% vs. 1.7%, p < 0.001), and a longer length of hospitalization (LOH) (Me = 11; IQR: 8-17 days vs. Me = 9; IQR: 6-13 days, p = 0.049) respectively. Patients with ALC DOC developed more frequently moderate AP vs. Non-ALC DOC (43.5% vs. 12.5%), while the incidence of severe AP was higher in Non-ALC vs. ALC DOC group (33.3% vs. 4.4%) (p < 0.001). LOH showed a tendency to be longer in Non-ALC DOC compared to ALC DOC, respectively (Me:13; IQR:7-20 days vs. Me:9.5; IQR:8-15.5 days, p = 0.119). CONCLUSION: DOC during AP is associated with a higher rate of moderate and severe AP and increases the risk of mortality.

BACKGROUND & AIMS: Pattern recognition receptors (PRRs) have a key role in the innate host defense. Functional polymorphisms of various PRRs have been established to contribute to an increased susceptibility to spontaneous bacterial peritonitis (SBP). Their role in the development of cirrhosis-associated bacterial infections (BI), beyond SBP or progressive disease course related to pathological bacterial translocation (BT) remains unknown. METHODS: Three hundred and forty-nine patients with cirrhosis were genotyped for common NOD2 (R702W, G908R and L1007PfsinsC), TLR2 (-16934T>A), and TLR4 (D299G) variants. Incidence of BIs, decompensating events and liver-related death were assessed in a 5-year follow-up observational study. Pathological BT was assessed based on the presence of antimicrobial antibodies or lipopolysaccharide-binding protein (LBP) level. RESULTS: In patients with ascites (n = 88) only NOD2 gene variants were associated with an increased cumulative probability of SBP (76.9% ± 19.9%) compared to wild-type (30.9% ± 6.9%, PLogRank = .047). Individual or combined PRR genetic profiles were associated with the risk of non-SBP type BI. Advanced disease stage (HR [95% CI]: 2.11 [1.38-3.25]) and prior history of a BI episode (HR: 2.42 [1.58-3.72]) were the major clinical risk factors of a subsequent BI. The risk of a non-SBP type BI in patients with advanced disease and a prior BI was even higher (HR: 4.74 [2.68-8.39]). The frequency of antimicrobial antibodies and LBP levels did not differ between various PRR genotypes. Correspondingly, PRR genetic profile was not able to predict the long-term disease course. CONCLUSIONS: In cirrhosis, functional polymorphisms of PRRs did not improve the identification of patients with high risk of BI beyond SBP or progressive diseases course.

BACKGROUND & AIMS: Lectin pathway molecules of the complement system are synthesized by hepatocytes and have pivotal role in innate host defence against infectious organisms. Ficolins (FCNs) act as soluble pattern recognition molecules, while mannan-binding lectin serine proteases(MASPs) do as effector molecules in elimination of pathogens. We aimed to study the significance of low level of these molecules in the development of cirrhosis-associated bacterial infections, which has not been elucidated so far. METHODS: Sera of 266 stable outpatients with cirrhosis and 160 healthy subjects were assayed for a panel of lectin molecules (FCN-2, FCN-3 and MASP-2) by ELISA. In cirrhosis, a 5-year follow-up observational study was conducted to assess a possible association between lectin levels and development of clinically significant bacterial infections(CSI). RESULTS: FCN-2, FCN-3 and MASP-2 levels were significantly lower in cirrhosis compared to healthy subjects and decreased according to disease severity (P<.001 for all molecules). In Kaplan-Meier analysis, development of CSI was associated with low level of FCN-2 (<427 ng/mL, pLogRank=0.047) and FCN-3 (<4857 ng/mL, pLogRank=0.029), but not with MASP-2 deficiency (<100 ng/mL, pLogRank=0.306). Combined FCN deficiency was associated with increased risk of development of bacterial infections in a step-wise manner. Patients with low level of both FCNs had higher cumulative probability of CSI (63.8%) compared to those with low level of one or normal FCN (52.7% and 45.7%, pLogRank=0.016). Neither FCN serum profile, nor MASP-2 deficiency were associated with infection-related mortality. CONCLUSIONS: Low level of FCNs associated with hepatic insufficiency might be considered as an additional constituent of cirrhosis-associated immune dysfunction.

Spontaneous bacterial peritonitis occurs most commonly in cirrhotic patients with ascites. Pathogens get into the circulation by intestinal translocation and colonize in peritoneal fluid. Diagnosis of spontaneous bacterial peritonitis is based on elevated polymorphonuclear leukocyte count in the ascites (>0,25 G/L). Ascites culture is often negative but aids to get information about antibiotic sensitivity in positive cases. Treatment in stable patient can be intravenous then orally administrated ciprofloxacin or amoxicillin/clavulanic acid, while in severe cases intravenous III. generation cephalosporin. Nosocomial spontaneous bacterial peritonitis often caused by Gram-positive bacteria and multi-resistant pathogens can also be expected thus carbapenem should be the choice of the empiric treatment. Antibiotic prophylaxis should be considered. Norfloxacin is used most commonly, but changes are expected due to increase in quinolone resistance. As a primary prophylaxis, a short-term antibiotic treatment is recommended after gastrointestinal bleeding for 5 days, while long-term prophylaxis is for patients with low ascites protein, and advanced disease (400 mg/day). Secondary prophylaxis is recommended for all patients recovered from spontaneous bacterial peritonitis. Due to increasing antibiotic use of antibiotics prophylaxis is debated to some degree. Orv. Hetil., 2017, 158(2), 50-57.

BACKGROUND & AIMS: Innate immune system dysfunction is common in advanced cirrhosis, with a central role of the monocyte/macrophage system. Monocytes and macrophages express the scavenger receptor CD163, which is regulated by inflammatory mediators. Cleavage of the receptor leads to the formation of soluble (s)CD163 that represents an anti-inflammatory response. We aimed to study the clinical importance of sCD163 in cirrhosis. METHODS: Sera of 378 patients were assayed for sCD163 by ELISA [193 outpatients and 185 patients with acute decompensation (AD)]. A 5-year follow-up observational study was conducted to assess the possible association between sCD163 level and poor disease outcomes. RESULTS: sCD163 level was associated with disease severity, but not with the presence of varices or prior variceal bleeding. In outpatients, sCD163 level did not predict the development of disease-specific complications or the long-term mortality. In patients with AD episode, sCD163 level was significantly higher compared to outpatients but only in the presence of bacterial infection (INF) (AD-INF:4586, AD-NON-INF:3792 and outpatients: 3538 ng/ml, P < 0.015 and P = 0.001, respectively). sCD163 level gradually increased according to severity of infection. During bacterial infections, high sCD163 level (>7000 ng/ml) was associated with increased mortality rate (42% vs. 17%, P < 0.001) and was identified as an independent predictor of 28-day mortality (hazard ratio:2.96, 95% confidence intervals:1.27-6.95) in multivariate Cox-regression model comprising aetiology, co-morbidity, model for end-stage liver disease score and leucocyte count as covariates. CONCLUSIONS: High sCD163 level is useful to identify patients with high-risk of death during an AD episode complicated by bacterial infection. This finding serves as an additional hint towards the significance of anti-inflammatory response during bacterial infection.

INTRODUCTION: The increasing incidence and poor prognosis of hepatocellular carcinoma places huge burden on healthcare. AIM: After reviewing literature on epidemiological trends, risk factors, diagnosis and management options for hepatocellular carcinoma, the authors investigated results of treatment and survival data of patients in Northeastern Hungary. METHOD: In a retrospective study, the authors analyzed medical records of 187 patients with hepatocellular carcinoma (etiology, presence of cirrhosis, stage of the tumor, treatment and disease outcome). RESULTS: Seventy-one patients (38%) had known cirrhosis at the diagnosis of hepatocellular carcinoma, while in 52 patients (28%) the presence of cirrhosis was established at the time of the diagnosis of hepatocellular carcinoma. Fifteen patients (8%) had no cirrhosis and in 49 patients (26%) no data were available regarding cirrhosis. Etiological factors were alcohol consumption (52%), viral hepatitis (41%) and metabolic syndrome (44%). In cases of metabolic syndrome, hepatocellular carcinoma frequently occurred without cirrhosis. In 83% of the cases, the tumor was discovered in an advanced stage. Median survival time was significantly associated with tumor stage (Barcelona A stage vs. B/C vs. D: 829 vs. 387 vs. 137 days, respectively p<0.001) but not with disease etiology (virus 282 days, metabolic syndrome 335 days and alcohol 423 days, p = 0.65). CONCLUSIONS: High mortality of hepatocellular carcinoma was mainly attributed to the delayed diagnosis of the disease. Screening of patients with cirrhosis could only result in a partial improvement since in a great proportion cirrhosis was diagnosed simultaneously with the tumor. Screening of diabetic and obese patients by ultrasonography should be considered. Management of baseline liver disease is of importance in the care of hepatocellular carcinoma. Orv. Hetil., 2016, 157(45), 1793-1801.

BACKGROUND: Increased lipase level is a serological hallmark of the diagnosis of acute pancreatitis (AP) but can be detected in various other diseases associated with lipase leakage due to inflammation of organs surrounding the pancreas or reduced renal clearance and/or hepatic metabolism. This non-pancreatic hyperlipasemia (NPHL) is puzzling for attending physicians during the diagnostic procedure for AP. It would be clinically beneficial to identify the clinical and laboratory variables that hinder the accuracy of lipase diagnosis with the aim of improve it. A more precise description of the NPHL condition could potentially provide prognostic factors for adverse outcomes which is currently lacking. AIM: To perform a detailed clinical and laboratory characterization of NPHL in a large prospective patient cohort with an assessment of parameters determining disease outcomes. METHODS: A Hungarian patient cohort with serum lipase levels at least three times higher than the upper limit of normal (ULN) was prospectively evaluated over 31 months. Patients were identified using daily electronic laboratory reports developed to support an ongoing observational, multicenter, prospective cohort study called the EASY trial (ISRCTN10525246) to establish a simple, easy, and accurate clinical scoring system for early prognostication of AP. Diagnosis of NPHL was established based on ≥ 3 × ULN serum lipase level in the absence of abdominal pain or abdominal imaging results characteristic of pancreatitis. RESULTS: A total of 808 patients [male, n = 420 (52%); median age (IQR): 65 (51-75) years] were diagnosed with ≥ 3 × ULN serum lipase levels. A total of 392 patients had AP, whereas 401 had NPHL with more than 20 different etiologies. Sepsis and acute kidney injury (AKI) were the most prevalent etiologies of NPHL (27.7% and 33.2%, respectively). The best discriminative cut-off value for lipase was ≥ 666 U/L (sensitivity, 71.4%; specificity, 88.8%). The presence of AKI or sepsis negatively affected the diagnostic performance of lipase. NPHL was associated with a higher in-hospital mortality than AP (22.4% vs 5.1%, P < 0.001). In multivariate binary logistic regression, not lipase but increased amylase level (> 244 U/L) and neutrophil-to-lymphocyte ratio (NLR) (> 10.37, OR: 3.71, 95%CI: 2.006-6.863, P < 0.001), decreased albumin level, age, and presence of sepsis were independent risk factors for in-hospital mortality in NPHL. CONCLUSION: NPHL is a common cause of lipase elevation and is associated with high mortality rates. Increased NLR value was associated with the highest mortality risk. The presence of sepsis/AKI significantly deteriorates the serological differentiation of AP from NPHL.

BACKGROUND & AIMS: Anti-neutrophil cytoplasmic antibodies (ANCA) are a non-uniform family of antibodies recognizing diverse components of neutrophil granulocytes. ANCA formation might be induced by protracted bacterial infections or probably reflect an abnormal immune response to commensal microorganisms. Bacterial infections are common complications in cirrhosis with high incidence of episodes caused by enteric organisms, therefore, we sought to study the presence and clinical importance of ANCA in cirrhosis. METHODS: Sera of 385 patients with cirrhosis of different etiologies were assayed for ANCA of IgG, IgA, IgA1, IgA2, and secretory IgA subtypes by indirect immunofluorescence and ELISAs. The control group comprised 202 patients with chronic liver diseases without cirrhosis and 100 healthy subjects. In cirrhosis, a 2-year follow-up, observational study was conducted to assess a possible association between the presence of ANCA and clinically significant bacterial infections. RESULTS: Prevalence of ANCA IgA was significantly higher in cirrhosis (52.2%) compared to chronic liver diseases (18.6%) or healthy controls (0%, p<0.001 for both). ANCA IgA subtyping assays revealed marked increase in the proportion of IgA2 subtype (46% of total ANCA IgA) and presence of the secretory component concurrently. Presence of ANCA IgA was associated with disease-specific clinical characteristics (Child-Pugh stage and presence of ascites, p<0.001). During a 2-year follow-up period, risk of infections was higher among patients with ANCA IgA compared to those without (41.8% vs. 23.4%, p<0.001). ANCA IgA positivity was associated with a shorter time to the first infectious complication (pLogRank <0.001) in Kaplan-Meier analysis and was identified as an independent predictor in multivariate Cox-regression analysis (HR:1.74, 95% CI: 1.18-2.56, p=0.006). CONCLUSIONS: Presence of IgA type ANCA is common in cirrhosis. Involvement of gut mucosal immune system is in center of their formation and probably reflects sustained exposure to bacterial constituents.

Liver cirrhosis patients are highly susceptible to infections, affecting survival, but current parameters for detecting infection are not reliable enough in this population. We investigated the ability of white blood cell (WBC), ∆WBC, neutrophil and ∆neutrophil counts, neutrophil-to-lymphocyte (NLR) and ∆NLR ratios and C-reactive protein (CRP) and procalcitonin (PCT) levels to identify infection and predict short-term mortality in liver cirrhosis patients. We recruited 233 patients with liver cirrhosis hospitalized with acute decompensation (AD) who had an outpatient visit within 1 month (baseline laboratory data) and followed them for 90 days. Difference between laboratory values at baseline and the AD episode was defined as delta (∆) values of the parameters. Delta values did not increase the diagnostic and predictive ability of investigated parameters. The CRP level was found to be the best diagnostic marker for infection in patients with cirrhosis. However, NLR seems to be superior for short-term mortality prediction, better than the WBC count. Distinguishing inflammations of different origin is a remaining clinical challenge in acutely decompensated cirrhosis. Based on our results, NLR might be more suitable for predicting short-term mortality in patients with AD than the WBC count currently included in the CLIF-C AD score.
RESUMO
BACKGROUND: Bacterial infections are common cause of morbidity and mortality in patients with cirrhosis. The early diagnosis of these infections is rather difficult. AIMS: To assess the accuracy of acute phase proteins in the identification of bacterial infections. METHODS: Concentration of C-reactive protein (CRP), procalcitonin (PCT), lipopolysaccharide-binding protein (LBP), sCD14 and antimicrobial antibodies were measured in serum of 368 well-characterized patients with cirrhosis of whom 139 had documented infection. Clinical data was gathered by reviewing the patients' medical charts. RESULTS: Serum levels of CRP, PCT and LBP were significantly higher in patients with clinically overt infections. Among the markers, CRP - using a 10 mg/L cut-off value- proved to be the most accurate in identifying patients with infection (AUC: 0.93). The accuracy of CRP, however, decreased in advanced stage of the disease, most probably because of the significantly elevated CRP levels in non-infected patients. Combination of CRP and PCT increased the sensitivity and negative predictive value, compared with CRP on its own, by 10 and 5% respectively. During a 3-month follow-up period in patients without overt infections, Kaplan-Meier and proportional Cox-regression analyses showed that a CRP value of >10 mg/L (P = 0.035) was independently associated with a shorter duration to progress to clinically significant bacterial infections. There was no correlation between acute phase protein levels and antimicrobial seroreactivity. CONCLUSIONS: C-reactive protein on its own is a sensitive screening test for the presence of bacterial infections in cirrhosis and is also a useful marker to predict the likelihood of clinically significant bacterial infections in patients without overt infections.

Although excessive alcohol consumption is by far the most frequent cause of recurrent acute pancreatitis (AP) cases, specific therapy is still not well established to prevent recurrence. Generally, psychological therapy (e.g., brief intervention (BI)) is the cornerstone of cessation programs; however, it is not yet widely used in everyday practice. We conducted a post-hoc analysis of a prospectively collected database. Patients suffering from alcohol-induced AP between 2016 and 2021 received 30 min BI by a physician. Patient-reported alcohol consumption, serum gamma-glutamyl-transferase (GGT) level, and mean corpuscular volume (MCV) of red blood cells were collected on admission and at the 1-month follow-up visit to monitor patients' drinking habits. Ninety-nine patients with alcohol-induced AP were enrolled in the study (mean age: 50 ± 11, 89% male). A significant decrease was detected both in mean GGT value (294 ± 251 U/L vs. 103 ± 113 U/L, p < 0.001) and in MCV level (93.7 ± 5.3 U/L vs. 92.1 ± 5.1 U/L, p < 0.001) in patients with elevated on-admission GGT levels. Notably, 79% of the patients (78/99) reported alcohol abstinence at the 1-month control visit. Brief intervention is an effective tool to reduce alcohol consumption and to prevent recurrent AP. Longitudinal randomized clinical studies are needed to identify the adequate structure and frequency of BIs in alcohol-induced AP.

INTRODUCTION: Pain is the most common symptom in acute pancreatitis (AP) and is among the diagnostic criteria. Therefore, we aimed to characterize acute abdominal pain in AP. METHODS: The Hungarian Pancreatic Study Group prospectively collected multicentre clinical data on 1435 adult AP patients between 2012 and 2017. Pain was characterized by its intensity (mild or intense), duration prior to admission (hours), localization (nine regions of the abdomen) and type (sharp, dull or cramping). RESULTS: 97.3% of patients (n = 1394) had pain on admission. Of the initial population with acute abdominal pain, 727 patients answered questions about pain intensity, 1148 about pain type, 1134 about pain localization and 1202 about pain duration. Pain was mostly intense (70%, n = 511/727), characterized by cramping (61%, n = 705/1148), mostly starting less than 24 h prior to admission (56.7%, n = 682/1202). Interestingly, 50.9% of the patients (n = 577/1134) had atypical pain, which means pain other than epigastric or belt-like upper abdominal pain. We observed a higher proportion of peripancreatic fluid collection (19.5% vs. 11.0%; p = 0.009) and oedematous pancreas (8.4% vs. 3.1%; p = 0.016) with intense pain. Sharp pain was associated with AP severity (OR = 2.481 95% CI: 1.550-3.969) and increased mortality (OR = 2.263, 95% CI: 1.199-4.059) compared to other types. Longstanding pain (>72 h) on admission was not associated with outcomes. Pain characteristics showed little association with the patient's baseline characteristics. CONCLUSION: A comprehensive patient interview should include questions about pain characteristics, including pain type. Patients with sharp and intense pain might need special monitoring and tailored pain management. SIGNIFICANCE: Acute abdominal pain is the leading presenting symptom in acute pancreatitis; however, we currently lack specific guidelines for pain assessment and management. In our cohort analysis, intense and sharp pain on admission was associated with higher odds for severe AP and several systemic and local complications. Therefore, a comprehensive patient interview should include questions about pain characteristics and patients with intense and sharp pain might need closer monitoring.

BACKGROUND: Acute pancreatitis (AP) is a potentially severe or even fatal inflammation of the pancreas. Early identification of patients at high risk for developing a severe course of the disease is crucial for preventing organ failure and death. Most of the former predictive scores require many parameters or at least 24 h to predict the severity; therefore, the early therapeutic window is often missed. METHODS: The early achievable severity index (EASY) is a multicentre, multinational, prospective and observational study (ISRCTN10525246). The predictions were made using machine learning models. We used the scikit-learn, xgboost and catboost Python packages for modelling. We evaluated our models using fourfold cross-validation, and the receiver operating characteristic (ROC) curve, the area under the ROC curve (AUC), and accuracy metrics were calculated on the union of the test sets of the cross-validation. The most critical factors and their contribution to the prediction were identified using a modern tool of explainable artificial intelligence called SHapley Additive exPlanations (SHAP). RESULTS: The prediction model was based on an international cohort of 1184 patients and a validation cohort of 3543 patients. The best performing model was an XGBoost classifier with an average AUC score of 0.81 ± 0.033 and an accuracy of 89.1%, and the model improved with experience. The six most influential features were the respiratory rate, body temperature, abdominal muscular reflex, gender, age and glucose level. Using the XGBoost machine learning algorithm for prediction, the SHAP values for the explanation and the bootstrapping method to estimate confidence, we developed a free and easy-to-use web application in the Streamlit Python-based framework (http://easy-app.org/). CONCLUSIONS: The EASY prediction score is a practical tool for identifying patients at high risk for severe AP within hours of hospital admission. The web application is available for clinicians and contributes to the improvement of the model.

BACKGROUND AND AIMS: Patients with cirrhosis are susceptible to bacterial infections (BIs) that are major causes of specific complications and mortality. However, the diagnosis of BIs can often be difficult in advanced disease stage since their symptoms may overlap with the ones of acute decompensation (AD). Soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) is released from monocytes/macrophages and neutrophils during activation and has been reported to correlate with activity of various inflammatory processes. We investigated its diagnostic and prognostic performance in patients with cirrhosis and BI. METHODS: Sera of 269 patients were assayed for sTREM-1 by ELISA (172 outpatients and 97 patients with AD of whom 56 had BI). We investigated capacity of sTREM-1 to identify patients with BI and conducted a 90-day follow-up observational study to assess its possible association with short-term mortality. RESULTS: sTREM-1 levels were significantly higher in patients with more severe liver disease, BI, and acute-on-chronic liver failure than in patients without these conditions. sTREM-1 had similar accuracy to CRP identifying BI [sTREM-1: AUROC (95%CI) 0.804 (0.711-0.897), pâ¯<â¯0.0001; CRP: 0.791 (0.702-0.881), pâ¯<â¯0.0001)] among AD patients. The combination of these two molecules and the presence of ascites into a composite score significantly increased their discriminative power (AUROC: 0.878, 95%CI: 0.812-0.944, pâ¯<â¯0.0001). High sTREM-1 level (>660â¯pg/mL) was an independent predictor of 90-day mortality in patients with BI [HR: 2.941, (95%CI: 1.009-8.573), pâ¯=â¯0.048] in our multivariate model. CONCLUSIONS: Use of sTREM-1 could increase the recognition of BIs in cirrhosis and help clinicians in mortality risk assessment of these patients.

BACKGROUND & AIMS: Mannose-binding lectin (MBL) is a serum lectin synthesized by the liver and involved in innate host defense. MBL deficiency increases the risk of various infectious diseases mostly in immune-deficient conditions. Bacterial infections are a significant cause of morbidity and mortality in liver cirrhosis due to the relative immuncompromised state. METHODS: Sera of 929 patients with various chronic liver diseases [autoimmune liver diseases (ALD), 406; viral hepatitis C (HCV), 185; and liver cirrhosis (LC) with various etiologies, 338] and 296 healthy controls (HC) were assayed for MBL concentration. Furthermore, a follow-up, observational study was conducted to assess MBL level as a risk factor for clinically significant bacterial infections in cirrhotic patients. RESULTS: MBL level and the prevalence of absolute MBL deficiency (<100 ng/ml) was not significantly different between patients and controls (ALD: 14.5%, HCV: 11.9%, LC: 10.7%, HC: 15.6%). In cirrhotic patients, the risk for infection was significantly higher among MBL deficient subjects as compared to non-deficient ones (50.0% vs. 31.8%, p=0.039). In a logistic regression analysis, MBL deficiency was an independent risk factor for infections (OR: 2.14 95% CI: 1.03-4.45, p=0.04) after adjusting for Child-Pugh score, co-morbidities, gender, and age. In a Kaplan-Meier analysis, MBL deficiency was associated with a shorter time to develop the first infectious complication (median days: 579 vs. 944, pBreslow=0.016, pLogRank=0.027) and was identified as an independent predictor in a multivariate Cox-regression analysis (p=0.003, OR: 2.33, 95% CI: 1.34-4.03). CONCLUSIONS: MBL deficiency is associated with a higher probability and shorter time of developing infections in liver cirrhosis, further supporting the impact of the MBL molecule on the host defense.

OBJECTIVES: Proton pump inhibitors(PPIs) are widely prescribed to patients with liver cirrhosis. We hypothesized that long-standing PPI use is associated with spontaneous bacterial peritonitis(SBP) and accelerated development of disease-specific complications and liver-related death. METHODS: A 5-year follow-up observational cohort study assessed the impact of long-standing PPI use on the clinical course of cirrhosis in a large referral patient cohort. Three hundred fifty patients with cirrhosis (alcohol:69.1%, Child-Pugh stage A/B/C:206/108/36) were assigned to two groups: regular PPI users (n=196) and nonusers (n=154). Occurrence of SBP, decompensation events (ascites, hepatic encephalopathy and variceal bleeding), and liver-related death were assessed. RESULTS: Regular PPI use was associated with an increased cumulative probability of SBP compared to nonusers [55% vs. 24.8%, hazard ratio(HR):4.25; P=0.05], in patients without previous SBP episode (n=84). A similar association was found between regular PPI use and decompensation events. The risk of the development of a first decompensation was higher in regular PPI users compared with nonusers, in patients with compensated clinical stage at enrollment (HR: 2.81, P= 0.008, n=146). The risk of liver-related death was also significantly increased among regular PPI users (P<0.001). In multivariate Cox-regression analysis, regular PPI use (HR:2.81, P=0.003) and MELD score (HR:1.21, P<0.001) was an independent predictor of mortality. CONCLUSION: In the present follow-up cohort study, long-term PPI use was associated with the development of SBP and a progressive disease course in patients with cirrhosis that may have been caused by enhanced pathologic bacterial translocation, accelerated development of bacterial translocation-dependent disease-specific complications, and liver-related death.

Gastrointestinal bleeding has a profound impact on public health due to its high prevalence and severity. With the elderly population taking more anticoagulants/antiaggregants/non-steroid anti-inflammatory drugs, the digestive bleeding will certainly raise more and more challenges in quantity as well as in severity for the public healthcare system. The emergency medicine specialists and gastroenterologists have a central role in the management of patients presenting with gastrointestinal bleeding. In certain cases, radiologists, invasive radiologists, intensive care specialists and surgeons should also be involved in the decision making process and management of patients. Therefore, Hungarian experts felt the need to elaborate a comprehensive, multidisciplinary, practical local guideline reflecting the frequently arisen aspects based on current international guidelines. This guideline proposal covers topics of basic requirements, initial assessment of patients, risk evaluation, laboratory tests, hemodynamic resuscitation in the case of gastrointestinal bleeding followed by its consecutive steps of diagnosis and therapy sorted by location of the source of the hemorrhage. The authors give practical instructions for unsuccessful hemostasis or rebleeding. Finally, the role of surgery is also summarized in the management of gastrointestinal bleeding.

INTRODUCTION: Acute pancreatitis (AP) is a life-threatening inflammatory disease of the exocrine pancreas which needs acute hospitalisation. Despite its importance, we have significant lack of knowledge whether the lifestyle factors elevate or decrease the risk of AP or influence the disease outcome. So far, no synthetising study has been carried out examining associations between socioeconomic factors, dietary habits, physical activity, chronic stress, sleep quality and AP. Accordingly, LIFESPAN identifies risk factors of acute pancreatitis and helps to prepare preventive recommendations for lifestyle elements. METHODS AND ANALYSIS: LIFESPAN is an observational, multicentre international case-control study. Participating subjects will create case and control groups. The study protocol was designed according to the SPIRIT guideline. Patients in the case group (n=1700) have suffered from AP (alcohol-induced, n=500; biliary, n=500; hypertriglyceridemiainduced, n=200; other, n=500); the control group subjects have no AP in their medical history. Our study will have three major control groups (n=2200): hospital-based (n=500), population-based (n=500) and aetiology-based (alcohol, n=500; biliary, n=500 and hypertriglyceridemia, n=200). All of them will be matched to the case group individually by gender, age and location of residence. Aggregately, 3900 subjects will be enrolled into the study. The study participants will complete a complex questionnaire with the help of a clinical research administrator/study nurse. Analysis methods include analysis of the continuous and categorical values. ETHICS AND DISSEMINATION: The study has obtained the relevant ethical approval (54175-2/2018/EKU) and also internationally registered (ISRCTN25940508). After obtaining the final conclusions, we will publish the data to the medical community and will also disseminate our results via open access. TRIAL REGISTRATION NUMBER: ISRCTN25940508; Pre-results.

BACKGROUND: Antibodies directed against Saccharomyces cerevisiae (ASCA), perinuclear components of neutrophils (pANCA), and porin protein C of Escherichia coli (anti-OmpC) are reported to be associated with disease phenotype and may be of diagnostic importance in inflammatory bowel disease (IBD). Since limited data are available from Eastern Europe, we assessed the above antibodies in Hungarian IBD patients. METHODS: In all, 653 well-characterized, unrelated consecutive IBD patients (Crohn's disease [CD]: 558, m/f: 263/295, duration: 8.1 +/- 10.7 years; ulcerative colitis [UC]: 95, m/f: 44/51, duration: 8.9 +/- 9.8 years) and 100 healthy subjects were investigated. Sera were assayed for anti-Omp and ASCA by enzyme-linked immunosorbent assay (ELISA) and ANCA by indirect immunofluorescence assay (IIF). TLR4 and NOD2/CARD15 variants were tested by polymerase chain reaction/restriction fragment length polymorphism (PCR-RFLP). Detailed clinical phenotypes were determined by reviewing the medical charts. RESULTS: Anti-Omp, ASCA, and atypical pANCA antibodies were present in 31.2%, 59.3%, and 13.8% of CD, 24.2%, 13.7%, and 48.5% of UC patients, and in 20%, 16%, and 5.6% of controls, respectively. ASCA and anti-Omp positivity were associated with increased risk for CD (odds ratio [OR](ASCA) = 7.65, 95% confidence interval [CI]: 4.37-13.4; OR(Omp) = 1.81, 95% CI: 1.08-3.05). In a logistic regression analysis, anti-Omp and ASCA were independently associated with ileal and noninflammatory disease, but not with a risk for surgery or response to steroids or infliximab. A serology dosage effect was also observed. ASCA and anti-Omp antibodies were associated with NOD2/CARD15, in addition to a gene dosage effect. No associations were found in UC. CONCLUSIONS: Serological markers were useful in the differentiation between CD and UC in an Eastern European IBD cohort. Reactivity to microbial components was associated with disease phenotype and NOD2/CARD15 genotype, further supporting the role of altered microbial sensing in the pathogenesis of CD.
