Inflammatory bowel disease does not alter the clinical features and the management of acute pancreatitis: A prospective, multicentre, exact-matched cohort analysis.

OBJECTIVE AND AIMS: Acute pancreatitis in inflammatory bowel disease occurs mainly as an extraintestinal manifestation or a side effect of medications. We aimed to investigate the prognostic factors and severity indicators of acute pancreatitis and the treatment of patients with both diseases. DESIGN: We performed a matched case-control registry analysis of a multicentre, prospective, international acute pancreatitis registry. Patients with both diseases were matched to patients with acute pancreatitis only in a 1:3 ratio by age and gender. Subgroup analyses were also carried out based on disease type, activity, and treatment of inflammatory bowel disease. RESULTS: No difference in prognostic factors (laboratory parameters, bedside index of severity in acute pancreatitis, imaging results) and outcomes of acute pancreatitis (length of hospitalization, severity, and local or systemic complications) were detected between groups. Significantly lower analgesic use was observed in the inflammatory bowel disease population. Antibiotic use during acute pancreatitis was significantly more common in the immunosuppressed group than in the non-immunosuppressed group (p = 0.017). However, none of the prognostic parameters or the severity indicators showed a significant difference between any subgroup of patients with inflammatory bowel disease. CONCLUSION: No significant differences in the prognosis and severity of acute pancreatitis could be detected between patients with both diseases and with pancreatitis only. The need for different acute pancreatitis management is not justified in the coexistence of inflammatory bowel disease, and antibiotic overuse should be avoided.

Glucose levels show independent and dose-dependent association with worsening acute pancreatitis outcomes: Post-hoc analysis of a prospective, international cohort of 2250 acute pancreatitis cases.

BACKGROUND: Metabolic risk factors, such as obesity, hypertension, and hyperlipidemia are independent risk factors for the development of various complications in acute pancreatitis (AP). Hypertriglyceridemia dose-dependently elicits pancreatotoxicity and worsens the outcomes of AP. The role of hyperglycemia, as a toxic metabolic factor in the clinical course of AP, has not been examined yet. METHODS: We analyzed a prospective, international cohort of 2250 AP patients, examining associations between (1) glycosylated hemoglobin (HbA1c), (2) on-admission glucose, (3) peak in-hospital glucose and clinically important outcomes (mortality, severity, complications, length of hospitalization (LOH), maximal C-reactive protein (CRP)). We conducted a binary logistic regression accounting for age, gender, etiology, diabetes, and our examined variables. Receiver Operating Characteristic Curve (ROC) was applied to detect the diagnostic accuracy of the three variables. RESULTS: Both on-admission and peak serum glucose are independently associated with AP severity and mortality, accounting for age, gender, known diabetes and AP etiology. They show a dose-dependent association with severity (p < 0.001 in both), mortality (p < 0.001), LOH (p < 0.001), maximal CRP (p < 0.001), systemic (p < 0.001) and local complications (p < 0.001). Patients with peak glucose >7 mmol/l had a 15 times higher odds for severe AP and a five times higher odds for mortality. We found a trend of increasing HbA1c with increasing LOH (p < 0.001), severity and local complications. CONCLUSIONS: On-admission and peak in-hospital glucose are independently and dose-dependently associated with increasing AP severity and mortality. In-hospital laboratory control of glucose and adequate treatment of hyperglycemia are crucial in the management of AP.

Development of disturbance of consciousness is associated with increased severity in acute pancreatitis.

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.

Acid suppression therapy, gastrointestinal bleeding and infection in acute pancreatitis - An international cohort study.

BACKGROUND: Acid suppressing drugs (ASD) are generally used in acute pancreatitis (AP); however, large cohorts are not available to understand their efficiency and safety. Therefore, our aims were to evaluate the association between the administration of ASDs, the outcome of AP, the frequency of gastrointestinal (GI) bleeding and GI infection in patients with AP. METHODS: We initiated an international survey and performed retrospective data analysis on AP patients hospitalized between January 2013 and December 2018. RESULTS: Data of 17,422 adult patients with AP were collected from 59 centers of 23 countries. We found that 23.3% of patients received ASDs before and 86.6% during the course of AP. ASDs were prescribed to 57.6% of patients at discharge. ASD administration was associated with more severe AP and higher mortality. GI bleeding was reported in 4.7% of patients, and it was associated with pancreatitis severity, mortality and ASD therapy. Stool culture test was performed in 6.3% of the patients with 28.4% positive results. Clostridium difficile was the cause of GI infection in 60.5% of cases. Among the patients with GI infections, 28.9% received ASDs, whereas 24.1% were without any acid suppression treatment. GI infection was associated with more severe pancreatitis and higher mortality. CONCLUSIONS: Although ASD therapy is widely used, it is unlikely to have beneficial effects either on the outcome of AP or on the prevention of GI bleeding during AP. Therefore, ASD therapy should be substantially decreased in the therapeutic management of AP.

Hypertriglyceridemia-induced acute pancreatitis: A prospective, multicenter, international cohort analysis of 716 acute pancreatitis cases.

BACKGROUND: Hypertriglyceridemia is the third most common cause of acute pancreatitis (AP). It has been shown that hypertriglyceridemia aggravates the severity and related complications of AP; however, detailed analyses of large cohorts are contradictory. Our aim was to investigate the dose-dependent effect of hypertriglyceridemia on AP. METHODS: AP patients over 18 years old who underwent triglyceride measurement within the initial three days were included into our cohort analysis from a prospective international, multicenter AP registry operated by the Hungarian Pancreatic Study Group. Data on 716 AP cases were analyzed. Six groups were created based on the highest triglyceride level (<1.7 mmol/l, 1.7-2.19 mmol/l, 2.2-5.59 mmol/l, 5.6-11.29 mmol/l, 11.3-22.59 mmol/l, ≥22.6 mmol/l). RESULTS: Hypertriglyceridemia (≥1.7 mmol/l) presented in 30.6% of the patients and was significantly and dose-dependently associated with younger age and male gender. In 7.7% of AP cases, hypertriglyceridemia was considered as a causative etiological factor (≥11.3 mmol/l); however, 43.6% of these cases were associated with other etiologies (alcohol and biliary). Hypertriglyceridemia was significantly and dose-dependently related to obesity and diabetes. The rates of local complications and organ failure and maximum CRP level were significantly and dose-dependently raised by hypertriglyceridemia. Triglyceride above 11.3 mmol/l was linked to a significantly higher incidence of moderately severe AP and longer hospital stay, whereas triglyceride over 22.6 mmol/l was significantly associated with severe AP as well. CONCLUSION: Hypertriglyceridemia dose-dependently aggravates the severity and related complications of AP. Diagnostic workup for hypertriglyceridemia requires better awareness regardless of the etiology of AP.

The Effects of a Fixed Combination of Berberis aristata and Silybum marianum on Dyslipidaemia - A Meta-analysis and Systematic Review.

A fixed combination of Berberis aristata and Silybum marianum (Berberol) has been used by patients with dyslipidaemia. The aim of the present meta-analysis was to systematically evaluate the efficacy and safety of a fixed combination of B. aristata and S. marianum (Berberol) on serum lipid levels compared to placebo in a meta-analysis based on randomised, controlled trials. The meta-analysis was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, using the PICO (patients, intervention, comparison, outcome) format, and it was registered in the International Prospective Register of Systematic Reviews. The Cochrane Central Register of Controlled Trials, PubMed, Embase, and Web of Science databases were searched for relevant studies. Placebo-controlled clinical studies involving adult patients with a condition of dyslipidaemia and receiving a fixed combination of B. aristata and S. marianum were included. Four randomised trials, including a total of 491 patients, were pooled in statistical analysis. According to the present meta-analysis, Berberol significantly lowered the low-density lipoprotein level, total cholesterol, fasting plasma glucose levels, and the Homeostatic Model Assessment index compared to placebo; however, its effects on the high-density lipoprotein level, triglyceride level, and body mass index were not statistically significant by the end of a 3-month treatment period. Berberol appeared to be safe, and it did not increase the levels of alanine transaminase, aspartate transaminase, and creatine kinase enzymes. Berberol is an effective and presumably safe complementary therapy for the treatment of dyslipidaemia; however, the evidence supporting its use is very limited. The optimum dose and duration of treatment are unclear. A comprehensive evaluation of efficacy and safety is required in further high-quality clinical studies involving larger patient populations.

Sarcopenia as an independent predictor of the surgical outcomes of patients with inflammatory bowel disease: a meta-analysis.

Patients with inflammatory bowel disease (IBD) are at risk of sarcopenia, which is associated with poor clinical outcomes. We conducted this study to assess whether sarcopenia predicts the need for surgery and postoperative complications in patients with IBD. We performed a systematic search of four electronic databases, last updated in March, 2019. Data from studies comparing rates of surgery and postoperative complications in sarcopenic IBD patients versus non-sarcopenic IBD patients were pooled with the random-effects models. We calculated the odds ratios (OR) with a 95% confidence interval (CI). Ten studies with a collective total of 885 IBD patients were included in our meta-analysis. Although the analysis of raw data did not reveal significant differences between the two groups with respect to the rate of surgery and postoperative complications (OR = 1.826; 95% CI 0.913-3.654; p = 0.089 and OR = 3.265; 95% CI 0.575-18.557; p = 0.182, respectively), the analysis of adjusted data identified sarcopenia as an independent predictor for both of the undesirable outcomes (OR = 2.655; 95% CI 1.121-6.336; p = 0.027 and OR = 6.097; 95% CI 1.756-21.175; p = 0.004, respectively). Thus, early detection of sarcopenia in patients with IBD is important to prevent undesirable outcomes.

A Cross-Sectional Survey on the Transitional Care of Adolescents with Inflammatory Bowel Disease in Hungary.

PURPOSE: Since little is known about transitional care practices of adolescents with inflammatory bowel diseases (IBD) in Central-Eastern Europe, we aimed to investigate the currently applied transition practices in Hungary. DESIGN AND METHODS: A nationwide, multicentre survey was conducted with the invitation of 41 pediatric and adult IBD centres in February 2019.We developed a 34-item questionnaire, which included single- and multiple-choice questions related to the current clinical practice of IBD transition. RESULTS: The overall response rate was 31.7% (13/41); answers came predominantly from tertiary centres. Only 15.4% of the respondent centres followed international IBD guidelines. The majority of the IBD centres provided transition support; however, responses revealed a marked heterogeneity of these services. Joint visits were held only in 54% of the clinics. Gastroenterologists and next of kin are not provided education regarding transition across most centres (85 and 92%). Although adolescents received age-specific education, transition readiness was not measured. More IBD nurses and dietitians were employed in adult centres than in pediatric ones. CONCLUSIONS: The current survey revealed critical gaps in the Hungarian IBD transition practices. As the beneficial effects of structured IBD transition programmes are recognized in Hungary, there is a growing need for the introduction of new, more effective transition practices. PRACTICE IMPLICATIONS: Our results can serve as a basis for planning more effective transition strategies.

Elevated urinary orosomucoid excretion as a novel biomarker in Crohn's disease.

BACKGROUND: Laboratory markers are essential tools in the follow-up of patients with Crohn's disease (CD). Our aim was to investigate urinary concentrations of orosomucoid in relation to the inflammatory activity of CD and to compare it with clinical indices and conventional laboratory parameters. MATERIALS AND METHODS: Blood and urine samples of 86 patients (55 adults and 31 children) with CD and 68 healthy individuals (38 adults and 30 children) as controls were analysed. Patients were categorized according to their clinical scores (Harvey-Bradshaw Index [HBI] or Pediatric Crohn's Disease Activity Index [PCDAI]). Urinary orosomucoid (u-ORM) was determined by automated immune turbidimetric assay, and values were referred to urinary creatinine (u-ORM/u-CREAT, mg/mmol). RESULTS: U-ORM/u-CREAT values were seven times higher in children with active CD (0.50 vs 0.07 mg/mmol, P < 0.001) and two times higher in adults (0.32 vs 0.14 mg/mmol, P = 0.01) compared with patients with inactive disease. U-ORM/u-CREAT showed good correlation with conventional inflammatory markers (hs-CRP, serum ORM; P < 0.01) and activity indices (HBI, P = 0.018; PCDAI, P < 0.001). U-ORM/u-CREAT had similar discriminative performance to hs-CRP and serum ORM in the differentiation of active from inactive paediatric CD patients. CONCLUSIONS: Our findings suggest that u-ORM/u-CREAT might serve as a valuable additional marker in the follow-up of CD patients, especially in children for whom the non-invasive sampling is a further advantage.

Antibiotic therapy in acute pancreatitis: From global overuse to evidence based recommendations.

BACKGROUND: Unwarranted administration of antibiotics in acute pancreatitis presents a global challenge. The clinical reasoning behind the misuse is poorly understood. Our aim was to investigate current clinical practices and develop recommendations that guide clinicians in prescribing antibiotic treatment in acute pancreatitis. METHODS: Four methods were used. 1) Systematic data collection was performed to summarize current evidence; 2) a retrospective questionnaire was developed to understand the current global clinical practice; 3) five years of prospectively collected data were analysed to identify the clinical parameters used by medical teams in the decision making process, and finally; 4) the UpToDate Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system was applied to provide evidence based recommendations for healthcare professionals. RESULTS: The systematic literature search revealed no consensus on the start of AB therapy in patients with no bacterial culture test. Retrospective data collection on 9728 patients from 22 countries indicated a wide range (31-82%) of antibiotic use frequency in AP. Analysis of 56 variables from 962 patients showed that clinicians initiate antibiotic therapy based on increased WBC and/or elevated CRP, lipase and amylase levels. The above mentioned four laboratory parameters showed no association with infection in the early phase of acute pancreatitis. Instead, procalcitonin levels proved to be a better biomarker of early infection. Patients with suspected infection because of fever had no benefit from antibiotic therapy. CONCLUSIONS: The authors formulated four consensus statements to urge reduction of unjustified antibiotic treatment in acute pancreatitis and to use procalcitonin rather than WBC or CRP as biomarkers to guide decision-making.

Planned Transition of Adolescent Patients with Inflammatory Bowel Disease Results in Higher Remission Rates.

PURPOSE: To evaluate the effect of our current transition process on clinical outcomes in adolescent patients with inflammatory bowel diseases (IBD). DESIGN AND METHODS: Two groups of patients with IBD diagnosed in pediatric care were compared retrospectively: Group A patients did not attend the transition process, while Group B patients entered the planned transition service. Outcomes at 1-year after transfer to adult care were evaluated. RESULTS: Forty-five patients with IBD diagnosed under the age of 18 years were identified of whom 35 had Crohn's disease and 10 had ulcerative colitis. Twenty-four patients were in Group A (without transition), and 21 patients in Group B (with at least one planned transition visit). Mean age at diagnosis was 15.1 ±â€¯2.2 and 13.7 ±â€¯3.0 years (p = 0.086), respectively. There were no significant differences in disease duration before transfer, Montreal classification at diagnosis, body mass index, anti-TNF therapy usage, and disease status at transfer between the two groups. A significantly higher number of Group B patients were in remission at 12 months after transfer when compared to patients in Group A (11 vs. 18, respectively, p = 0.037). There was a significant difference between groups regarding the number of scheduled visits within the examined period (9 vs. 16, p = 0.011, respectively). CONCLUSIONS: Planned transition visits resulted in higher disease remission rate at 1-year follow-up after transfer from pediatric to adult health care system in adolescent patients with IBD. PRACTICE IMPLICATION: Well-established transition programs in IBD are needed.

Capsaicin and capsiate could be appropriate agents for treatment of obesity: A meta-analysis of human studies.

Consumption of capsaicin or its nonpungent analogues, capsinoids has been reported to affect energy expenditure and fat oxidation, although available data are still controversial. The aim of the present study was to conduct a meta-analysis regarding the effects of these substances on energy expenditure and respiratory quotient, with special emphasis on the role of body mass index (BMI) of the participants. Medical databases were systematically searched for papers. Of the 627 trials identified, 9 provided results suitable to be included in analysis. Data analysis showed that after ingestion of capsaicin or capsinoids the energy expenditure increased (245 kJ/day, 58.56 kcal/day, p = 0.030) and the respiratory quotient decreased (by 0.216; p = 0.031) indicating a rise in fat oxidation. Studies with mean BMI of the participants below 25 kg/m2 failed to report any effect of capsaicin or capsinoids on the energy expenditure (p = 0.718) or on the respiratory quotient (p = 0.444), but studies with mean BMI exceeding 25 kg/m2 demonstrated an increase in energy expenditure (292 kJ/day, 69.79 kcal/day, p = 0.023) and a marked decrease in respiratory quotient (-0.257, p = 0.036). Our data clearly suggest that capsaicin or capsiate could be a new therapeutic approach in obesity promoting a negative energy balance and increased fat oxidation.

Helicobacter pylori infection reduces the risk of Barrett's esophagus: A meta-analysis and systematic review.

INTRODUCTION: The prevalence of Helicobacter pylori infection (HPI) has been decreasing in developed countries, with an increasing prevalence of Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) at the same time. The aim of our meta-analysis was to quantify the risk of BE in the context of HPI. METHODS: A systematic search was conducted in 3 databases for studies on BE with data on prevalence of HPI from inception until December 2016. Odds ratios for BE in HPI were calculated by the random effects model with subgroup analyses for geographical location, presence of dysplasia in BE, and length of the BE segment. RESULTS: Seventy-two studies were included in the meta-analysis, including 84 717 BE cases and 390 749 controls. The overall analysis showed that HPI reduces the risk of BE; OR = 0.68 (95% CI: 0.58-0.79, P < .001). Subgroup analyses revealed risk reduction in Asia OR = 0.53 (95% CI: 0.33-0.84, P = .007), Australia OR = 0.56 (95% CI: 0.39-0.80, P = .002), Europe OR = 0.77 (95% CI: 0.60-0.98, P = .035), and North-America OR = 0.59 (95% CI: 0.47-0.74, P < .001). The risk was significantly reduced for dysplastic BE, OR = 0.37 (95% CI: 0.26-0.51, P < .001) for non-dysplastic BE, OR = 0.51 (95% CI: 0.35-0.75, P = .001), and for long segment BE, OR = 0.25 (95% CI: 0.11-0.59, P = .001) in case of HPI. CONCLUSIONS: This extensive meta-analysis provides additional evidence that HPI is associated with reduced risk of BE. Subgroup analyses confirmed that this risk reduction is independent of geographical location. HPI is associated with significantly lower risk of dysplastic, non-dysplastic, and long segment BE.

Eosinophil Counts in the Small Intestine and Colon of Children Without Apparent Gastrointestinal Disease: A Meta-analysis.

The aim of the current study was to review the available data regarding eosinophil density in healthy tissue specimen originating from lower gastrointestinal segments to support suggested diagnostic cutoffs widely used in clinical practice. A systematic search was performed in 3 different databases. Calculations were made with Comprehensive MetaAnalysis software using random-effects model. Cell number measurements were pooled using the random-effects model and displayed on forest plots. Summary point estimations, 95% confidence intervals (CIs), and 95% prediction intervals (PIs) were calculated. The cumulative mean cell numbers were 8.26 (95% CI 4.71-11.80) with PI of 0-25.32 for the duodenum, 11.52 (95% CI 7.21-15.83) with PI 0-60.64 for the terminal ileum, and 11.10/ high-power field (HPF) (95% CI 9.11-13.09) with PI of 0.96 to 21.23 in the large intestine and the rectum (HPF area = 0.2 mm). Previous studies included control patients with irritable bowel syndrome and functional gastrointestinal disorders. As mucosal eosinophils have a role in their pathomechanism, those patients should have been excluded. A critical point of interpreting reported data is that HPF is relative to the technical parameters of the microscopes; therefore, it is important to report findings in cell/mm. The present meta-analysis does not support the higher (>20) or lower (<10) cutoff values for healthy tissue eosinophil number. In contrast to the esophagus, there is no normal cutoff eosinophil density in the small intestine and the colon. A prospective, multicenter study to establish normal mucosal eosinophil density is clearly needed.

Gender difference in the effects of interleukin-6 on grip strength - a systematic review and meta-analysis.

BACKGROUND: Aging sarcopenia characterized by low muscle mass with low muscle strength affects men and women differently. The contribution of interleukin-6 (IL-6) to sarcopenia has been suggested based on a negative correlation between plasma IL-6 and muscle function described by some studies. However, no consensus regarding clinically relevant cut-off criteria has been reached. Another question arises whether pooling male and female data is an accurate way to determine the predictive value of IL-6 in sarcopenia. The present meta-analysis was designed to assess: (1) whether plasma IL-6 in aged populations in fact correlates negatively to muscle strength; (2) whether such a correlation exists both in men and in women; and (3) whether plasma IL-6 shows a gender difference in old age. METHODS: We applied the preferred reporting items for systematic review and meta-analysis protocols (PRISMA). We searched PubMed and Embase for papers that reported data on individuals over 65 without inflammatory diseases. We extracted either separate male and female data on plasma IL-6 along with at least one muscle parameter or correlation coefficient between plasma IL-6 and these parameters. Random effect models calculated with DerSimonian and Laird weighting methods were applied to analyze correlation coefficients and gender difference in plasma IL-6. Egger's test was used to assess the small study effect. RESULTS: Twenty articles out of 468 records identified were suitable for analyses. Plasma IL-6 correlates negatively with grip strength in mixed populations and also separately in men [- 0.25 with 95% confidence interval (CI): - 0.48, - 0.02] and in women (- 0.14 with 95% CI: - 0.24, - 0.03). However, contrary to expectations, men with better muscle condition have higher plasma IL-6 than women of similar age with worse muscle condition (plasma IL-6 male-female difference: 0.25 pg/mL with 95% CI: 0.15, 0.35). CONCLUSION: This is the first study to demonstrate that a higher predictive IL-6 cut-off level should be determined for aging sarcopenia in men than in women.

Elevated Expression of AXL May Contribute to the Epithelial-to-Mesenchymal Transition in Inflammatory Bowel Disease Patients.

Understanding the molecular mechanisms inducing and regulating epithelial-to-mesenchymal transition (EMT) upon chronic intestinal inflammation is critical for understanding the exact pathomechanism of inflammatory bowel disease (IBD). The aim of this study was to determine the expression profile of TAM family receptors in an inflamed colon. For this, we used a rat model of experimental colitis and also collected samples from colons of IBD patients. Samples were taken from both inflamed and uninflamed regions of the same colon; the total RNA was isolated, and the mRNA and microRNA expressions were monitored. We have determined that AXL is highly induced in active-inflamed colon, which is accompanied with reduced expression of AXL-regulating microRNAs. In addition, the expression of genes responsible for inducing or maintaining mesenchymal phenotype, such as SNAI1, ZEB2, VIM, MMP9, and HIF1α, were all significantly induced in the active-inflamed colon of IBD patients while the epithelial marker E-cadherin (CDH1) was downregulated. We also show that, in vitro, monocytic and colonic epithelial cells increase the expression of AXL in response to LPS or TNFα stimuli, respectively. In summary, we identified several interacting genes and microRNAs with mutually exclusive expression pattern in active-inflamed colon of IBD patients. Our results shed light onto a possible AXL- and microRNA-mediated regulation influencing epithelial-to-mesenchymal transition in IBD.

Transpancreatic sphincterotomy has a higher cannulation success rate than needle-knife precut papillotomy - a meta-analysis.

Background and aim While many studies have discussed the different cannulation techniques used in patients with difficult biliary access, no previous meta-analyses have compared transpancreatic sphincterotomy (TPS) to other advanced techniques. Therefore, we aimed to identify all studies comparing the efficacy and adverse event rates of TPS with needle-knife precut papillotomy (NKPP), the most commonly used technique, and to perform a meta-analysis. Methods The Embase, PubMed, and Cochrane databases were searched for trials comparing the outcomes of TPS with NKPP up till December 2016. A meta-analysis focusing on outcome (cannulation success, post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP), post-procedural bleeding, and total adverse events) was performed. The population, intervention, comparison, outcome (PICO) format was used to compare these cannulation approaches. Five prospective and eight retrospective studies were included in our meta-analysis. Results NKPP has a significantly lower success rate (odds ratio [OR] 0.50, P = 0.046; relative risk [RR] 0.92, P = 0.03) and a higher rate of bleeding complications (OR 2.24, P = 0.02; RR 2.18, P = 0.02) than TPS. However, no significant differences were found in PEP (OR 0.79, P = 0.24; RR 0.80, P = 0.19), perforation (risk difference [RD] 0.01, P = 0.23), or total complication rates (OR 1.22, P = 0.44; RR 1.17, P = 0.47). Conclusion While TPS has a higher success rate in difficult biliary access and causes less bleeding than NKPP, there are no differences in PEP, perforation, or total complication rates between the two approaches. We conclude that TPS, in the hands of expert endoscopists, is a safe procedure, which should be used more widely in patients with difficult biliary access.

Meta-Analysis of Early Nutrition: The Benefits of Enteral Feeding Compared to a Nil Per Os Diet Not Only in Severe, but Also in Mild and Moderate Acute Pancreatitis.

The recently published guidelines for acute pancreatitis (AP) suggest that enteral nutrition (EN) should be the primary therapy in patients suffering from severe acute pancreatitis (SAP); however, none of the guidelines have recommendations on mild and moderate AP (MAP). A meta-analysis was performed using the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P). The following PICO (problem, intervention, comparison, outcome) was applied: P: nutrition in AP; I: enteral nutrition (EN); C: nil per os diet (NPO); and O: outcome. There were 717 articles found in Embase, 831 in PubMed, and 10 in the Cochrane database. Altogether, seven SAP and six MAP articles were suitable for analyses. In SAP, forest plots were used to illustrate three primary endpoints (mortality, multiorgan failure, and intervention). In MAP, 14 additional secondary endpoints were analyzed (such as CRP (C-reactive protein), WCC (white cell count), complications, etc.). After pooling the data, the Mann-Whitney U test was used to detect significant differences. Funnel plots were created for testing heterogeneity. All of the primary endpoints investigated showed that EN is beneficial vs. NPO in SAP. In MAP, all of the six articles found merit in EN. Analyses of the primary endpoints did not show significant differences between the groups; however, analyzing the 17 endpoints together showed a significant difference in favor of EN vs. NPO. EN is beneficial compared to a nil per os diet not only in severe, but also in mild and moderate AP.

Marked differences of haplotype tagging SNP distribution, linkage, and haplotype profile of IL23 receptor gene in Roma and Hungarian population samples.

Polymorphisms of the interleukin-23 receptor (IL23R) gene have been found to play an important role in the development of several autoimmune diseases. We examined five susceptible (rs10889677, rs1004819, rs2201841, rs11805303, rs11209032), one protective (rs7517847) and two neutral variants (rs7530511, rs1884444) of the IL23R gene in pooled DNA of healthy Roma (Gipsy) and Hungarian population samples. Our aim was to determine the genetic variability of the major haplotype tagging polymorphisms, and the haplotype profile of IL23R between the two groups. We analyzed 273 healthy Roma and 253 Hungarian DNA samples using PCR/RFLP assay. Comparing the five susceptible conferring alleles, there were significant increase (p<0.05), while in the protective alleles, there were decrease in the allele frequencies in Roma population (p<0.05). One of the neutral alleles showed increase, the another one did not differ between the two groups. The haplotype analysis of the SNPs revealed fundamentally different association types of SNPs in the two groups; moreover, the frequencies of the various haplotypes also exhibited strong differences, as of ht4 and ht5 haplotypes were significantly higher, whereas the frequencies of ht2 and ht3 haplotypes were significantly lower in the Roma population than in Hungarians (p<0.05). The data presented here show profound differences in the IL23R genetic profiles in the Roma population, that likely has also clinical implications in respect their possible role in the development of certain immunological diseases.

INTRODUCTION: One of the most serious complications of liver cirrhosis is variceal bleeding. Early recognition of the oesophageal varices is of primary importance in the prevention of variceal bleeding. Endoscopy is the only means to directly visualize varices and measure their size, as one of the most important predictor of the risk of bleeding. During the course of cirrhosis repeated oesophago-gastro-bulboscopic examinations are recommended. As these interventions are expensive and often poorly accepted by patients who may refuse further follow-up, there is a need for non-invasive methods to predict the progression of portal hypertension as well as the presence and the size of oesophageal varices. After several combinations of biological and ultrasonographical parameters proposed for the detection of advanced fibrosis, it was suggested that liver stiffness measured by transient elastography, a novel non-invasive technology may reflect not only fibrosis and portal pressure but it may even predict the presence or absence of large oesophageal varices in patients with cirrhosis. AIM: The aim of the authors was to study the diagnostic accuracy of transient elastography using FibroScan for selecting patients who are at risk of bearing large (Paquet-grade ≥ II) oesophageal varices and high risk of bleeding. METHOD: The authors performed upper tract endoscopy and transient elastography in 74 patients with chronic liver disease (27 patients with chronic hepatitis and 47 patients with liver cirrhosis). The relationships between the presence of oesophageal varices (Paquet-grade 0-IV) and liver stiffness (kPa), as well as the hematological and biochemical laboratory parameters (prothrombine international normalized ratio, platelet count, aspartate aminotransferase, alanine aminotransferase, albumin, and aspartate aminotransferase/platelet ratio index) were investigated. The predictive role of liver stiffness for screening patients with varices and those who are at high risk of variceal bleeding was also analysed. RESULTS: Liver stiffness values significantly correlated with the grade of oesophageal varices (Paquet-grade) (r = 0.67, p<0.0001). The liver stiffness value of 19.2 kPa was highly predictive for the presence of oesophageal varices (AUROC: 0.885, 95% CI: 0.81-0.96) and for the presence of high grade varices (P≥II) (AUROC: 0.850, 95% CI: 0.754-0.94). Using the cut-off value of 19.2 kPa, the sensitivity of transient elastography was 85%, specificity was 87%, positive predictive value was 85%, negative predictive value was 87% and validity was 86% for the detection of varices. Liver stiffness values less than 19.2 kPa were highly predicitive for the absence of large (P≥II) varices (sensitivity, 95%; specificity, 70%; positive predictive value, 54%; negative predictive value, 97%). CONCLUSIONS: Transient elastography may help to screen patients who are at high risk of bearing large (P≥II) oesophageal varices which predict variceal bleeding and, therefore, need endoscopic screening. Lives stiffness values higher than 19.2 kPa indicate the need for oesophageal-gastro-bulboscopy, while liver stiffness values lower than 19.2 kPa make the presence of large oesophageal varices unlikely.
