Aims: In this observational study, we investigated whether specialized care improves outcomes for acute pancreatitis (AP).Methods: Consecutive patients admitted to two university hospitals with AP were enrolled in this study between 1 January 2016 and 31 December 2016 (Center A: specialized center; Center B: general hospital). Data on demographic characteristics and AP etiology, severity, mortality and quality of care (enteral nutrition and antibiotic use) were extracted from the Hungarian Acute Pancreatitis Registry. An independent sample t-test, Mann–Whitney test, chi-squared test or Fisher’s test were used for statistical analyses. Costs of care were calculated and compared in the two models of care.Results: There were 355 patients enrolled, 195 patients in the specialized center (Center A) and 160 patients in the general hospital (Center B). There was no difference in mean age (57.02 ±17.16 vs. 57.31 ±16.50 P=0.872) and sex ratio (56% males vs. 57% males, P=0.837) between centres, allowing a comparison without selection bias. Center A had lower mortality (n=2, 1.03% vs. n=16, 6.25%, p=0.007), more patients received enteral feeding (n=179, 91.8%, vs. n=36, 22.5%, p

Background and Aims Inflammatory bowel disease [IBD] is associated with a 1.5- to 3-fold increased risk of venous thromboembolism [VTE] events. The aim of this study was to determine the risk of VTE in IBD as a complication of systemic corticosteroids and anti-tumour necrosis factor alpha [TNFα] therapies. Methods A systematic review and meta-analysis was conducted, which conforms to the Preferred Reporting Items for Systematic Reviews and Meta-analyses [PRISMA] statement. PubMed, EMBASE, Cochrane Library and Web of Science were searched for English-language studies published from inception inclusive of 15 April 2017. The population-intervention-comparison-outcome [PICO] format and statistically the random-effects and fixed-effect models were used to compare VTE risk during steroid and anti-TNFα treatment. Quality of the included studies was assessed using the Newcastle-Ottawa scale. The PROSPERO registration number is 42017070084. Results We identified 817 records, of which eight observational studies, involving 58518 IBD patients, were eligible for quantitative synthesis. In total, 3260 thromboembolic events occurred. Systemic corticosteroids were associated with a significantly higher rate of VTE complication in IBD patients as compared to IBD patients without steroid medication (odds ratio [OR]: 2.202; 95% confidence interval [CI]: 1.698-2.856, p < 0.001). In contrast, treatment with anti-TNFα agents resulted in a 5-fold decreased risk of VTE compared to steroid medication [OR: 0.267; 95% CI: 0.106-0.674, p = 0.005]. Conclusion VTE risk should be carefully assessed and considered when deciding between anti-TNFα and steroids in the management of severe flare-ups. Thromboprophylaxis guidelines should be followed, no matter the therapy choice.

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.

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.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.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).DOC during AP is associated with a higher rate of moderate and severe AP and increases the risk of mortality.

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. (C) 2020 IAP and EPC. Published by Elsevier B.V.

BackgroundAcute pancreatitis (AP) is an inflammatory condition that can lead to late consequences. Recurrent AP (RAP) develops in 20% of patients and chronic pancreatitis (CP) occurs in 7%–12.8%. However, we do not have sufficient information to establish an evidence-based statement to define early CP, or how to prevent its development.AimThe aim of this study was to understand the influencing factors and to determine which parameters should be measured or used as a biomarker to detect the early phase of CP.Methods/DesignThis is an observational prospective follow-up study of the GOULASH-trial (ISRTCN 63827758) in which (1) all severity of pancreatitis are included; (2) patients receive only therapeutic modalities which are accepted by the evidence based medicine (EBM) guideline; (3) whole blood, serum and plasma samples are stored in our biobank; and (4) large amount of variables are collected and kept in our electronic database including anamnestic data, physical examination, laboratory parameters, imaging, therapy and complications. Therefore, this fully characterised patient cohort are well suitable for this longitudinal follow-up study. Patients’ selection: patients enrolled in the GOULASH study will be offered to join to the longitudinal study. The follow-up will be at 1, 2, 3, 4, 5 and 6 years after the episode of AP. Anamnestic data will be collected by questionnaires: (1) diet history questionnaire, (2) 36-Item Short-Form Health Survey, (3) physical activity questionnaire and (4) stress questionnaire. Genetic tests will be performed for the genes associated with CP. The exocrine and endocrine pancreatic, liver and kidney functions will be determined by laboratory tests, stool sample analyses and imaging. Cost-effectiveness will be analysed to examine the relationship between events of interest and health-related quality of life or to explore subgroup differences.ConclusionThis study will provide information about the risk and influencing factors leading to CP and identify the most useful measurable parameters.Trial registration numberISRCTN63396106

Aim To compare the efficacy and safety of stent insertion alone to stent insertion combined with any active oncological treatment in the palliative care of esophageal cancer. Methods A meta-analysis and systematic review were performed according to the PRISMA Statement. Comparative studies with patients receiving stent insertion alone (control group) were compared to patients receiving oncological therapy in addition to stent placement (intervention group). For mean dysphagia grade before stenting, weighted mean differences (WMD), for the complications of stenting, risk ratios (RR) were calculated, both were interpreted with 95% confidence intervals (CI). Whenever possible, subgroup analyses were performed for studies with irradiation stents as intervention. Survival, late dysphagia, esophageal perforation and medical costs were analyzed via systematic review. The protocol of the study was registered prior on PROSPERO. Results 17 studies with 1177 esophageal cancer patients were included in the final analysis, with 629 and 548 in the control and intervention groups, respectively. We found no significant difference in any complications of stenting between the two groups. 13 studies reported mean or median survival, and 8 found that combined therapy resulted in a significantly longer life expectancy. In the other 5 studies, there was no difference in survival between the two groups. Furthermore, additional treatment may be more effective in the long-term relief of dysphagia than stenting alone. Conclusions Irradiation stents may prolong survival, and stenting combined with oncological treatment does not increase the risk of complications as compared to stenting alone. However, further studies are warranted. Core tip Esophageal cancer is the eighth most common type of malignancy worldwide, and its prognosis is very poor. This suggests that palliative treatment modalities are paramount in its treatment. Self-expanding metal stents play an important role in the management of dysphagia caused by the tumor. However, it is unclear whether any additional oncological therapy should be administered to patients besides stenting. In this meta-analysis and systematic review, we evaluated the safety and efficacy of additional oncological therapies alongside stenting versus stenting alone in case of unresectable esophageal cancer.

BackgroundTransition of adolescents from pediatric to adult care is of great importance in the management of inflammatory bowel disease (IBD). Our aim was to review and summarize the currently applied interventions and outcomes related to transition practices in IBD.MethodsA systematic review was performed in accordance with the PRISMA Statement. We searched PubMed, EMBASE, CENTRAL, and Web of Science databases up to February 15, 2019. Controlled studies evaluating adolescents and young adults with IBD participating in structured transition interventions or patient educational programs and single-arm (before-after) studies were included. Several individual, health care, and social outcomes were assessed. The PROSPERO registration number is CRD42019118520.ResultsA total of 23 articles were eligible for qualitative synthesis. Eleven studies compared an intervention to a control group, whilst 12 studies were uncontrolled before-after studies. The age of the participants varied from 11 to 25 years. The most common structured transition interventions were joint visits and patient education programs. IBD nurses were operating as nominated transition coordinators in the transition process. Quality of life, patient satisfaction, self-efficacy, disease-specific knowledge, adherence rate, and nonattendance rate at outpatient clinic were identified as main health care transition outcomes besides disease-related outcomes. Despite the various study designs and methodological limitations, outcomes improved with the application of structured transition interventions in eleven of the studies.ConclusionThese results facilitate the design of randomized controlled trials along better standards in transitional care in IBD.

Background and aimsExperimental data suggest that the HLA-DQ2 gene dose has a strong quantitative effect on clinical outcomes and severity of celiac disease (CD). We aimed to conduct a meta-analysis with systematic review to investigate the association between HLA-DQB1*02 gene doses and the characteristics of CD.MethodsWe searched seven medical databases for studies discussing HLA-DQB1 gene dose in CD and various disease characteristics, such as clinical presentation, histology, age at diagnosis, and comorbidities. Odds ratios (OR, for categorical variables) and weighted mean differences (for age) were calculated to compare patients with a double dose of HLA-DQB1*02 versus those with single and zero doses. Heterogeneity was tested with I2-statistics and explored by study subgroups (children and adults).ResultsTwenty-four publications were eligible for meta-analysis. Classical CD was more frequent with a double versus single dose of the HLA-DQB1*02 allele (OR = 1.758, 95%CI: 1.148-2.692, I2 = 0.0%). In pediatric studies, gene dose effect was more prominent (OR = 2.082, 95%CI: 1.189-3.646, I2 = 0.0% and OR = 3.139, 95%CI: 1.142-8.630, I2 = 0.0% for the comparisons of double versus single and double versus zero dose, respectively). Atrophic histology was more prevalent with a double versus zero dose (OR = 2.626, CI: 1.060-6.505, I2 = 21.3%). We observed no gene dose effect regarding diarrhea, age at diagnosis, the severity of villous atrophy, and the association with type 1 diabetes mellitus.ConclusionA double dose of HLA-DQB1*02 gene seems to predispose patients to developing classical CD and villous atrophy. Risk stratification by HLA-DQB1*02 gene dose requires further clarification due to the limited available evidence.

Although evidence indicates that use of procalcitonin to guide antibiotic decisions for the treatment of acute respiratory infections (ARI) decreases antibiotic consumption and improves clinical outcomes, algorithms used within studies had differences in PCT cut-off points and frequency of testing. We therefore analyzed studies evaluating procalcitonin-guided antibiotic therapy and propose consensus algorithms for different respiratory infection types. Areas covered: We systematically searched randomized-controlled trials (search strategy updated on February 2018) on procalcitonin-guided antibiotic therapy of ARI in adults using a pre-specified Cochrane protocol and analyzed algorithms from 32 trials that included 10,285 patients treated in primary care settings, emergency departments (ED), and intensive care units (ICU). We derived consensus algorithms for use of procalcitonin by the type of ARI including community-acquired pneumonia, bronchitis, chronic obstructive pulmonary disease or asthma exacerbation, sepsis, and post-operative sepsis due to respiratory infection. Consensus algorithm recommendations differ with regard to timing of treatment (i.e. timing of initiation in low-risk patients or discontinuation in high-risk patients) and procalcitonin cut-off points for the recommendation/strong recommendation to discontinue antibiotics (≤ 0.25/≤ 0.1 µg/L in ED and inpatients, ≤ 0.5/≤ 0.25 µg/L in ICU patients, and reduction by ≥ 80% from peak levels in sepsis patients). Expert commentary: Our proposed algorithms may facilitate safe and efficient implementation of procalcitonin-guided antibiotic protocols in diverse healthcare settings. Still, the decision about initiation and cessation of antibiotic treatment remains a clinical decision based on the patient assessment and the severity of illness and use of procalcitonin should not delay empirical treatment in high risk situations. info:eu-repo/semantics/publishedVersion

Introduction: Our meta-analysis indicated that aging influences the outcomes of acute pancreatitis (AP), however, a potential role for comorbidities was implicated, as well. Here, we aimed to determine how age and comorbidities modify the outcomes in AP in a cohort-analysis of Hungarian AP cases. Materials and Methods: Data of patients diagnosed with AP by the revised Atlanta criteria were extracted from the Hungarian Registry for Pancreatic Patients. Outcomes of interest were mortality, severity, length of hospitalization, local, and systemic complications of AP. Comorbidities were measured by means of Charlson Comorbidity Index (CCI) covering pre-existing chronic conditions. Non-parametric univariate and multivariate statistics were used in statistical analysis. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Results: A total of 1203 patients from 18 centers were included. Median age at admission was 58 years (range: 18–95 years), median CCI was 2 (range: 0–10). Only severe comorbidities (CCI ≥ 3) predicted mortality (OR = 4.48; CI: 1.57–12.80). Although severe comorbidities predicted AP severity (OR = 2.10, CI: 1.08–4.09), middle (35–64 years) and old age (≥65 years) were strong predictors with borderline significance, as well (OR = 7.40, CI: 0.99–55.31 and OR = 6.92, CI: 0.91–52.70, respectively). Similarly, middle and old age predicted a length of hospitalization ≥9 days. Interestingly, the middle-aged patients (35–64 years) were three times more likely to develop pancreatic necrosis than young adults (OR = 3.21, CI: 1.26–8.19), whereas the old-aged (≥65 years) were almost nine times more likely to develop systemic complications than young adults (OR = 8.93, CI: 1.20–66.80), though having severe comorbidities (CCI ≥ 3) was a predisposing factor, as well. Conclusion: Our results proved that both aging and comorbidities modify the outcomes of AP. Comorbidities determine mortality whereas both comorbidities and aging predict severity of AP. Regarding complications, middle-aged patients are the most likely to develop local complications; in contrast, those having severe comorbidities are prone to develop systemic complications. Studies validating the implementation of CCI-based predictive scores are awaited.

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 ± 2.2 and 13.7 ± 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.

Background Metformin is the first-choice drug for patients with Type 2 diabetes, and this therapy is characterized by being weight neutral. However, in the elderly an additional unintentional weight loss could be considered as an adverse effect of the treatment. Objectives We aimed to perform a meta-analysis of placebo-controlled studies investigating the body weight changes upon metformin treatment in participants older than 60 years. Materials and methods PubMed, EMBASE and the Cochrane Library were searched. We included at least 12 week-long studies with placebo control where the mean age of the metformin-treated patients was 60 years or older and the body weight changes of the patients were reported. We registered our protocol on PROSPERO (CRD42017055287). Results From the 971 articles identified by the search, 6 randomized placebo-controlled studies (RCTs) were included in the meta-analysis (n = 1541 participants). A raw difference of -2.23 kg (95% CI: -2.84 –-1.62 kg) body weight change was detected in the metformin-treated groups as compared with that of the placebo groups (p

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

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

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.

OBJECTIVES: 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 cut-offs widely used in clinical practice. METHODS: A systematic search was performed in three 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. RESULTS: The cumulative mean cell numbers were 8.26 (95% CI: 3.49, 13.03) with PI of 0-25.32 for the duodenum, 11.51 (95% CI: 7.21, 15.82) with PI of 0-60.59 for the terminal ileum, and 11.10/HPF (95% CI: 9.11, 13.09) with PI of 0.96-21.23 in the large intestine and the rectum (HPF area = 0.2 mm). Previous studies included control patients with irritable bowel syndrome (IBS) and functional GI 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. CONCLUSIONS: The present meta-analysis does not support the higher (>20) or lower (

Background & Aim: Endoscopic balloon dilation (EBD) and laparoscopic Heller myotomy (LHM) are the most commonly performed treatment options for achalasia. Decision between these treatment options is difficult. The aim of this meta-analysis was to evaluate the efficacy of EBD compared to LHM.Methods: The electronic databases PubMed, Embase and Cochrane Controlled Trials Registry were systematically searched for the period between January 1, 1976 and December 31, 2015. Meta-analysis was performed using the PICOS (problem, intervention, comparison, outcome, study design) format. Efficacy and safety of EBD were compared to LHM. Forest plot analyses were used to illustrate the success rate, perforation rate and post-procedural gastroesophageal reflux.Results: Using the search strategy, eight studies met the selection criteria and were included in the meta-analysis. The total number of patients included was 749 (360 in the EBD group and 389 in the LHM group). The success rate was lower in the EBD group than in the LHM group (OR=0.486; CI: 0.304-0.779; p=0.003). The rate of perforation did not differ significantly between the EBD and LHM group (RR= 0.635, CI: 0.340-1.186, p=0.154). The incidence of post-procedural symptomatic gastroesophageal reflux did not differ between the two treatment groups (RR=0.663, CI: 0.328-1.343, p=0.254).Conclusion: Our data suggest that the efficacy of LHM is superior to that of EBD, while there is no difference in safety between the two treatment groups.Abbreviations: EBD: endoscopic balloon dilation; GERD: gastro-esophageal reflux disease; LES: lower esophageal sphincter; LHM: laparascopic Heller myotomy; OR: odds ratio; PICOS: Problem, Intervention, Comparison, Outcome, Study design; POEM: Per Oral Endoscopic Myotomy; PRISMA: Preferred Reporting Items for Systematic Reviews and Meta-Analysis; RR: risk ratio.

Background and aims Persistent intestinal damage is associated with higher complication rates in celiac disease. We aimed to assess the potential modifiers of mucosal recovery. Materials and methods We screened databases (PubMed, Embase, Cochrane Trials, and Web of Science) for papers on celiac disease. Papers discussing (1) celiac patients (2) follow-up biopsy and (3) mucosal recovery after commencement of a gluten-free diet were included. The primary outcome was to produce a comprehensive analysis of complete mucosal recovery (i.e., Marsh 0 on follow-up). We compared children’s recovery ratios to those of adults. Patients following a strict gluten-free dietary regimen were included in a subgroup. Summary point estimates, 95% confidence intervals (CIs), and 95% predictive intervals (PIs) were calculated. Heterogeneity was tested with I2-statistic. The PROSPERO registration number is CRD42016053482. Results The overall complete mucosal recovery ratio, calculated from 37 observational studies, was 0.36 (CI: 0.28–0.44, PI: -0.12–0.84; I2: 98.4%, p

Background Inflammatory bowel diseases (IBD) patients are at increased risk for mental health problems. Managing IBD patients requires cooperation between gastroenterologists and psychologists and psychiatrists. We would like to assess the frequency of depression and suicidal thoughts among Hungarian IBD patients. Methods Multicentre, questionnaire-based survey among inflammatory bowel diseases patients. Demographic data and patient’s medical history was obtained with self-filling questionnaires. Patients’ psychic status was measured with Patient’s Health Questionnaire (PHQ-9), Beck Hopelessness Scale (short version). The survey was conducted in 3 IBD centres in Hungary, First Department of Medicine, University of Szeged, First Department of Surgery, University of Semmelweis and First Department of Medicine, University of Pécs. Results Three hundred IBD patients filled the questionnaires from the 3 IBD centres. Female-male ratio was 57% - 47%. Mean age at the time of the study was 38.8 years (SD 12.5) and mean disease duration was 11.5 years (SD 8.2). Sixty-two point three% was diagnosed with Crohn’s disease, 37.7% with ulcerative colitis, one patients reported IBD unclassified and three patients did not know the type of IBD. Sixty-nine point three% of the patients self-reported the remission state of IBD, while 30.7% self-reported to have active IBD. Proportion of patients on each category of PHQ-9 scale were the followings: severe 2%, moderate to severe 5.3%, moderate 21.3%, mild 33.6% and 37.6% had normal score. Nine point three% of the patients had elevated suicidal risk. More severe PHQ-9 category was associated with elevated risk for suicide. Significant difference was shown in the Hopelessness Scale’s results among the two genders, female patients had higher risks for suicidal thoughts. Those IBD patients in remission have lower probability for moderate or severe depression. Conclusion We have to be aware of that every IBD patient has increased risk for depression and suicide. Among our patients the rate of moderate to severe and severe depression was relatively low. Every tenth of our patients had elevated risk of suicide.

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.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.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.Liver stiffness values significantly correlated with the grade of oesophageal varices (Paquet-grade) (r = 0.67, p0.0001). 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%).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.Bevezetés: A májcirrhosis egyik legsúlyosabb szövődményének, a nyelőcsővarix-vérzésnek a prevenciójában a varixok korai felismerése és kezelése alapvető fontosságú. A vérzés kockázata függ a fibrosis/cirrhosis előrehaladásával súlyosbodó portalis hypertoniától és a varixok nagyságától. A varixdiagnosztika eszköze az endoszkópia, amire a kórlefolyás alatt ismételten szükség lehet a varixméret alakulásának követésére. Mivel az ismételt endoszkópos vizsgálatok nemcsak költségesek, hanem gyakran a betegek ellenállásába is ütközhetnek, felvetődött, hogy nem invazív eljárással lehetne-e kiszűrni a vérzés veszélyének különösen kitett, nagy varixokat hordozó betegeket, illetve csökkenteni a feleslegesnek tartható endoszkópiák számát. Célkitűzés: A varixvérzés kockázatának felmérésére a fibrosisstádium megítélésére használt tranziens elasztográfiát is ajánlották, ezért a szerzők célul tűzték ki e módszer prediktív szerepének vizsgálatát oesophagogastrobulboscopiával vizsgált májbetegekben. Módszer: 27 krónikus hepatitises és 47 cirrhosisos beteget vizsgáltak, akik etiológia szerint hepatitis B-vírus- (n = 4), illetve C-vírus-fertőzésben (n = 24), primer biliaris cirrhosisban (n = 12), nem alkoholos steatohepatitisben (n = 12), alkoholos (n = 11), autoimmun hepatitis (n = 9) és cryptogen cirrhosis (n = 2) eredetű kórképekben szenvedtek. Felső endoszkópiával megállapították a nyelőcső-varicositas Paquet szerinti súlyosságát (P0–IV), és párhuzamosan tranziens elasztográfiával a fibrosist jelző májtömöttséget. Vizsgálták a varicositasnak a vérkép, a szérumtranszamináz, gamma-glutamiltranszferáz, albumin és protombin, valamint a fibrosist jelző aszpartát-aminotranszferáz/thrombocyta hányados indexértékekkel való összefüggését is. Eredmények: A májtömöttség korrelált a Paquet-súlyossággal (r = 0,67, p0,0001). Az adatok alapján 19,2 kPa májtömöttségérték varix jelenlétére vonatkozóan 85%-os szenzitivitású, 86%-os specificitású, míg a PII–PIV súlyosságú varixok kockázatát illetően 95% szenzitivitású és 70% specificitású, pozitív prediktív értéke 54%, negatív prediktív értéke 97%. Következtetések: A tranziens elasztográfia segíti a nyelőcsővarix-vérzés kockázatának kitett betegek kiszűrését, akiknek feltehetően P≥II súlyosságú varicositásuk van, és endoszkópos vizsgálatot igényelnek. 19,2 kP feletti májtömöttség esetén a betegek 85%-ában lehet számítani varix jelenlétére; ilyen esetekben oesophagogastrobulboscopia javasolt. Ugyanakkor a 19,2 kP alatti májtömöttség esetén kicsi a valószínűsége P≥II súlyosságú varicositásnak. A tranziens elasztográfia nem helyettesíti a cirrhosis diagnosztikája során ajánlott endoszkópiát, de a kórlefolyás alatt csökkentheti az ismételt endoszkópiák számát. Orv.

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 BM...

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.

Objective The aim of this study was to analyse the clinical characteristics of acute pancreatitis (AP) in a prospectively collected, large, multicentre cohort and to validate the major recommendations in the IAP/APA evidence-based guidelines for the management of AP. Design Eighty-six different clinical parameters were collected using an electronic clinical research form designed by the Hungarian Pancreatic Study Group. Patients 600 adult patients diagnosed with AP were prospectively enrolled from 17 Hungarian centres over a two-year period from 1 January 2013. Main Results With respect to aetiology, biliary and alcoholic pancreatitis represented the two most common forms of AP. The prevalence of biliary AP was higher in women, whereas alcoholic AP was more common in men. Hyperlipidaemia was a risk factor for severity, lack of serum enzyme elevation posed a risk for severe AP, and lack of abdominal pain at admission demonstrated a risk for mortality. Abdominal tenderness developed in all the patients with severe AP, while lack of abdominal tenderness was a favourable sign for mortality. Importantly, lung injury at admission was associated with mortality. With regard to laboratory parameters, white blood cell count and CRP were the two most sensitive indicators for severe AP. The most common local complication was peripancreatic fluid, whereas the most common distant organ failure in severe AP was lung injury. Deviation from the recommendations in the IAP/APA evidence-based guidelines on fluid replacement, enteral nutrition and timing of interventions increased severity and mortality. Conclusions Analysis of a large, nationwide, prospective cohort of AP cases allowed for the identification of important determinants of severity and mortality. Evidence-based guidelines should be observed rigorously to improve outcomes in AP.

IntroductionHaemorheological and haemostatic changes predispose to the development of arterial and venous thrombotic events; however, limited information is available on the status of these changes in coeliac disease (CeD) and inflammatory bowel disease (IBD). In this study, we aim to describe the haemorheological and haemostatic profiles of CeD and IBD patients in a Hungarian cohort of patients to investigate whether any alterations contribute to elevated thrombotic risk.Methods and analysisThis is a case–control study involving newly diagnosed and followed CeD and IBD patients with age-matched and sex-matched non-CeD, non-IBD subjects with an allocation ratio of 1:1:1.After informed consent is obtained, a detailed medical history will be collected, including venous and arterial thrombotic risk factors and medications. Symptoms in CeD patients will be assessed with the Gastrointestinal Symptoms Rating Scale, and disease activity in IBD patients will be determined by disease-specific scores. Dietary adherence will be assessed among CeD patients with a thorough interview together with a measurement of self-reported adherence, dietary knowledge and urine analysis (detection of gluten immunogenic peptides). In addition to routine laboratory parameters, haemorheological (ie, erythrocyte deformability and aggregation, viscosity of whole blood and plasma) and haemostatic parameters (eg, protein C, protein S and antithrombin) with immunological indicators (ie, coeliac-specific serology and antiphospholipid antibodies) will be measured from venous blood for every participant.Primary and secondary outcomes will be haemorheological and haemostatic parameters, respectively. Univariate and multivariate statistics will be used to compare CeD and IBD patients to control subjects. Subgroup analysis will be performed by disease type in IBD, (Crohn’s disease and ulcerose colitis), dietary adherence in CeD, and disease activity in IBD and CeD.Ethics and disseminationThe study was approved by the Regional and Local Research Ethics Committee, University of Pécs (Ref. No. 6917). Findings will be disseminated at research conferences and in peer-reviewed journals.Trial registration numberISRCTN49677481.
