Abstract
INTRODUCTION Faecal microbiota transplantation (FMT) is an established therapy for recurrent C. difficile infection, and recent studies have reported encouraging results of FMT in patients with ulcerative colitis. Few international consensus guidelines exist for this therapy, and thus FMT policies and practices differ among European countries. As of 2019, stool transplants are considered a non-standardised medicinal product in Switzerland, and a standardised production process requires authorisation by the Swiss Agency for Therapeutic Products. This authorisation leads to prolonged administrative procedures and increasing costs, which reduces treatment accessibility. In particular, patients with ulcerative colitis in Switzerland can only benefit from FMT off-label, even though it is a valid therapeutic option. Therefore, this study summarised the available data on FMT and established a framework for the standardised use of FMT. METHODS A panel of Swiss gastroenterologists with a special interest in inflammatory bowel disease was established to identify the current key issues of FMT. After a comprehensive review of the literature, statements were formulated about FMT indications, donor screening, stool transplant preparation and administration, and safety aspects. The panel then voted on the statements following the Delphi process; the statements were reformulated and revoted until a consensus was reached. The manuscript was then reviewed by an infectiologist (the head of Lausanne's FMT centre). RESULTS The established statements are summarised in the supplementary tables in the appendix to this paper. The working group hopes these will help standardise FMT practice in Switzerland and contribute to making faecal microbiota transplantation a safe and accessible treatment for patients with recurrent C. difficile infections and selected patients with ulcerative colitis, as well as other indications in the future.

Abstract
INTRODUCTION There is a complex interrelationship between gastroesophageal reflux disease (GERD) and eosinophilic esophagitis (EoE) potentially promoting the occurrence and modulating severity of each other reciprocally. Presence of Barrett's esophagus (BE) is a defining factor for the diagnosis of GERD. While several studies investigated the potential impact of concomitant GERD on the presentation and course of EoE, little was known with regards to BE in EoE patients. METHODS We analyzed prospectively collected clinical, endoscopic, and histological data from patients enrolled in the Swiss Eosinophilic Esophagitis Cohort Study (SEECS) regarding differences between EoE patients with (EoE/BE+) versus without BE (EoE/BE-) and determined the prevalence of BE in EoE patients. RESULTS Among a total of 509 EoE patients included in our analysis, 24 (4.7%) had concomitant BE with a high male preponderance (EoE/BE+ 83.3% vs. EoE/BE- 74.4%). While there were no differences in dysphagia, odynophagia was significantly (12.5 vs. 3.1%, p = 0.047) more common in EoE/BE+ versus EoE/BE-. General well-being at last follow-up was significantly lower in EoE/BE+. Endoscopically, we observed an increased incidence of fixed rings in the proximal esophagus in EoE/BE+ (70.8 vs. 46.3% in EoE/BE-, p = 0.019) and a higher fraction of patients with a severe fibrosis in the proximal histological specimen (8.7 vs. 1.6% in EoE/BE, p = 0.017). CONCLUSION Our study reveals that BE is twice as frequent in EoE patients compared to general population. Despite many similarities between EoE patients with and without BE, the finding of a more pronounced remodeling in EoE patients with Barrett is noteworthy.

Abstract
A 60-year-old female patient with longstanding left-sided ulcerative colitis presented with symptoms mimicking an acute flare and developed a colonic perforation shortly after starting steroid treatment. Following left hemicolectomy and Hartmann's procedure, rescue treatment with infliximab was started. Within a few days, the patient developed hepatic failure. Histology and immunohistochemistry of the specimen revealed extensive necrotizing herpes simplex virus colitis, and liver biopsy demonstrated herpes simplex virus hepatitis. Sixteen days after admission, the patient died from multiorgan failure. This compelling case of severe herpes simplex virus colitis raises awareness of a rare but potentially detrimental infection in patients with inflammatory bowel disease.

Abstract
OBJECTIVE Transnasal esophagoscopy (TNE) in the awake patient and esophagogastroduodenoscopy (EGD) in sedation are both used in the assessment of laryngopharyngeal reflux (LPR). The objective of this study was to compare these two endoscopic methods in contributing to the diagnosis of LPR. METHODS This study included 54 patients presenting with signs and symptoms suspicious for LPR, which were examined both by TNE and EGD. The contribution of each method to the diagnosis of LPR was evaluated separately and then compared with each other. RESULTS In detecting LPR, TNE showed a significant higher sensitivity (94% vs. 60%) and accuracy (93% vs. 59%) than EGD, but their specificity was equal (50% each). The most common pathologic findings in both methods were a hiatal hernia (70% vs. 48%) and gaping cardia (69% vs. 24%), followed by peptic esophagitis (41% vs. 24%). CONCLUSION The value of EGD is limited in the workup of LPR, as sedation tends to mask the subtle findings in this kind of reflux disease.

Abstract
BACKGROUND Visible abdominal distension has been attributed to: (A) distorted perception, (B) intestinal gas accumulation, or (C) abdominophrenic dyssynergia (diaphragmatic push and anterior wall relaxation). METHODS A pool of consecutive patients with functional gut disorders and visible abdominal distension included in previous studies (n = 139) was analyzed. Patients (61 functional bloating, 74 constipation-predominant irritable bowel syndrome and 4 with alternating bowel habit) were evaluated twice, under basal conditions and during a self-reported episode of visible abdominal distension; static abdominal CT images were taken in 104 patients, and dynamic EMG recordings of the abdominal walls in 76, with diaphragmatic activity valid for analysis in 35. KEY RESULTS (A) Objective evidence of abdominal distension was obtained by tape measure (increase in girth in 138 of 139 patients), by CT imaging (increased abdominal perimeter in 96 of 104 patients) and by abdominal EMG (reduced activity, i.e., relaxation, in 73 of 76 patients). (B) Intestinal gas volume was within ±300 ml from the basal value in 99 patients, and above in 5 patients, who nevertheless exhibited a diaphragmatic descent. (C) Diaphragmatic contraction was detected in 34 of 35 patients by EMG (increased activity) and in 82 of 103 patients by CT (diaphragmatic descent). CONCLUSIONS AND INFERENCES In most patients complaining of episodes of visible abdominal distention: (A) the subjective claim is substantiated by objective evidence; (B) an increase in intestinal gas does not justify visible abdominal distention; (C) abdominophrenic dyssynergia is consistently evidenced by dynamic EMG recording, but static CT imaging has less sensitivity.

Abstract
OBJECTIVE Mucosal-associated invariant T (MAIT) cells are the most abundant T cells in human liver. They respond to bacterial metabolites presented by major histocompatibility complex-like molecule MR1. MAIT cells exert regulatory and antimicrobial functions and are implicated in liver fibrogenesis. It is not well understood which liver cells function as antigen (Ag)-presenting cells for MAIT cells, and under which conditions stimulatory Ags reach the circulation. DESIGN We used different types of primary human liver cells in Ag-presentation assays to blood-derived and liver-derived MAIT cells. We assessed MAIT cell stimulatory potential of serum from healthy subjects and patients with portal hypertension undergoing transjugular intrahepatic portosystemic shunt stent, and patients with inflammatory bowel disease (IBD). RESULTS MAIT cells were dispersed throughout healthy human liver and all tested liver cell types stimulated MAIT cells, hepatocytes being most efficient. MAIT cell activation by liver cells occurred in response to bacterial lysate and pure Ag, and was prevented by non-activating MR1 ligands. Serum derived from peripheral and portal blood, and from patients with IBD stimulated MAIT cells in MR1-dependent manner. CONCLUSION Our findings reveal previously unrecognised roles of liver cells in Ag metabolism and activation of MAIT cells, repression of which creates an opportunity to design antifibrotic therapies. The presence of MAIT cell stimulatory Ags in serum rationalises the observed activated MAIT cell phenotype in liver. Increased serum levels of gut-derived MAIT cell stimulatory ligands in patients with impaired intestinal barrier function indicate that intrahepatic Ag-presentation may represent an important step in the development of liver disease.

Abstract
Background Despite the fast establishment of new therapeutic agents in the management of COVID-19 and large-scale vaccination campaigns since the beginning of the SARS-CoV-2 pandemic in early 2020, severe disease courses still represent a threat, especially to patients with risk factors. This indicates the need for alternative strategies to prevent respiratory complications like acute respiratory distress syndrome (ARDS) associated with COVID-19. Aviptadil, a synthetic form of human vasoactive intestinal peptide, might be beneficial for COVID-19 patients at high risk of developing ARDS because of its ability to influence the regulation of exaggerated pro-inflammatory proteins and orchestrate the lung homeostasis. Aviptadil has recently been shown to considerably improve the prognosis of ARDS in COVID-19 when applied intravenously. An inhaled application of aviptadil has the advantages of achieving a higher concentration in the lung tissue, fast onset of activity, avoiding the hepatic first-pass metabolism, and the reduction of adverse effects. The overall objective of this project is to assess the efficacy and safety of inhaled aviptadil in patients hospitalized for COVID-19 at high risk of developing ARDS. Methods This multicenter, placebo-controlled, double-blinded, randomized trial with 132 adult patients hospitalized for COVID-19 and at high risk for ARDS (adapted early acute lung injury score ≥ 2 points) is conducted in five public hospitals in Europe. Key exclusion criteria are mechanical ventilation at baseline, need for intensive care at baseline, and severe hemodynamic instability. Patients are randomly allocated to either inhale 67 μg aviptadil or normal saline (three times a day for 10 days), in addition to standard care, stratified by center. The primary endpoint is time from hospitalization to clinical improvement, defined as either hospital discharge, or improvement of at least two levels on the nine-level scale for clinical status suggested by the World Health Organization. Discussion Treatment strategies for COVID-19 are still limited. In the context of upcoming new variants of SARS-CoV-2 and possible inefficacy of the available vaccines and antibody therapies, the investigation of alternative therapy options plays a crucial role in decreasing associated mortality and improving prognosis. Due to its unique immunomodulating properties also targeting the SARS-CoV-2 pathways, inhaled aviptadil may have the potential to prevent ARDS in COVID-19.

Abstract
Abstract
Objective
Standard treatment for uncomplicated diverticulitis in our institution consists of antibiotics. However, current evidence suggests that bacterial infection has a less predominant role than previously thought, and that uncomplicated acute diverticulitis may be a self-limiting condition in which inflammation can be managed without antibiotics. With the support of a multidisciplinary team we developed an intervention in order to reduce the use of antibiotics for patients with uncomplicated diverticular disease.
Methods
Standard practice and knowledge of current evidence were investigated with a structured survey sent to general practitioners and gastroenterologists with private practice in the area. A clinical process model for treatment of uncomplicated left-sided diverticulitis was created and exclusion criteria were selected in order to define patients with a high risk of developing complications. An educational intervention based on current evidence and the new treatment pathway was conducted on hospital staff as well as primary care physicians in the area in order to raise awareness about the possibility of avoiding antibiotics in uncomplicated diverticulitis. Patients were also involved and received an informative sheet about the rationale of the new treatment, the planned follow up and warning signs warranting further investigations and referral in case of outpatient treatment. All patients from May 2021 to December 2021 with a computed tomography-verified left-sided acute uncomplicated diverticulitis were included in the study and evaluated prospectively.
Results
Of 60 patients with acute uncomplicated diverticulitis, 23 (38%) were eligible for treatment without antibiotics. High inflammatory markers on presentation were the main reason (84%) for giving antibiotics. Adherence to the new policy was 74%. None of the 17 patients initially managed without antibiotics failed conservative treatment.
Conclusion
This project confirmed that treatment of uncomplicated diverticulitis without antibiotics can successfully be offered to a selected group of patients without altering the course of the disease. Further efforts are needed in order to overcome existing barriers to rational antimicrobial use such as lack of trust in new guidelines, general uncertainty and risk avoidance, patients’ expectations for antibiotic treatment, and fear of legal consequences.

Abstract
AIM OF THE STUDY Diagnosing small bowel pathology is challenging, and the diagnostic yield of small bowel capsule endoscopy is highly variable. Faecal calprotectin is a non-invasive intestinal inflammation marker that could be used as a selection tool to identify patients who might benefit from small bowel capsule endoscopy and increase its diagnostic yield. This study aimed to investigate the value of faecal calprotectin in detecting small bowel lesions in an unselected patient population. METHODS We performed a retrospective analysis of consecutive patients who underwent small bowel capsule endoscopy at the University Hospital Basel and the University Medical Clinic Cantonal Hospital Baselland, Switzerland, between 2010 and 2018. Patients without faecal calprotectin testing were excluded from the analysis. The primary endpoint was the presence of a clinically significant small bowel finding. RESULTS Patients with positive faecal calprotectin results were more likely to have small bowel findings (66.7% vs 39.4%; P = 0.007). The optimal faecal calprotectin cut-off to identify clinically significant small bowel lesions was 63 μg/g with 78.3% (95% confidence interval: 66.7-87.9) sensitivity, 47.9% (33.3-62.8) specificity, 1.50 (1.1-2.0) positive and 0.45 (0.3-0.8) negative likelihood ratios, 68.4% (61.6-74.4) positive and 60.5% (47.3-72.4) negative predictive values, and 65.0% overall accuracy. Faecal calprotectin performed best in patients with suspected inflammatory bowel disease, with 66.7% (48.2-82.0) sensitivity, 70.6% (44.0-89.7) specificity, 2.27 (1.0-4.9) positive and 0.47 (0.3-0.8) negative likelihood ratios, 81.5% (67.0-90.5) positive and 54.5% (39.7-68.6) negative predictive values, and 71.4% overall accuracy. CONCLUSION Faecal calprotectin testing increases the diagnostic yield of small bowel capsule endoscopy and may help identify patients at risk of small bowel disease.

Abstract
BACKGROUND Tumor necrosis factor (TNF) inhibitors have improved treatment of ulcerative colitis (UC), but loss of response remains a frequent problem. The anti-TNF agent, golimumab, was approved in Switzerland for the treatment of UC in 2014. This study aims to summarize the experience of golimumab in a real-world setting in Switzerland. METHODS We analyzed real-world data from 1769 UC patients from the Swiss Inflammatory Bowel Disease Cohort (SIBDC) study and performed a chart review of golimumab-treated patients. We extracted the partial Mayo score at t0 (baseline), t1 (2-16 weeks), t2 (17-35 weeks), and t3 (36-89 weeks). The primary endpoint was clinical response at t1, defined as marked improvement in partial Mayo score and objective parameters. Clinical remission was defined as resolution of symptoms and normalization of objective parameters. RESULTS Our chart review included 103 UC patients with golimumab treatment (5.8% of all SIBDC UC patients); only 16 (15.5%) were anti-TNF naïve. Sixty-three patients remained on golimumab (61.2%) after 180 days, 51 (44.7%) after 365 days, and 34 (33%) after 630 days after the start of treatment. Upon golimumab treatment, the partial Mayo score decreased from 4 [interquartile range (IQR): 2-6] at t0 to 2 (IQR: 0-4) at t1, 1 (IQR: 0-3.5) at t2, and 1 (IQR: 0-3) at t3 (p < 0.001 for all comparisons with t0). The primary endpoint, clinical response at t1, could be evaluated in 52 patients and was met in 15 individuals (28.8%). Clinical remission at t1 was observed in 8 out of 52 patients (15.4%). Golimumab was generally well tolerated, one patient developed meningitis. The most frequent reasons to stop treatment were primary and secondary non-response. CONCLUSION Golimumab was used in 5.8% of Swiss UC patients, mainly in biologic-experienced individuals. Golimumab treatment was associated with a sustained reduction of symptoms and clinical response in approximately 30% of patients.[ClinicalTrials.gov identifier: NCT00488631].

Abstract
Interventional endoscopy in hepatico-pancreatico-biliary disease Abstract. Interventional endoscopy has undergone an exciting evolution in recent years, especially in the treatment of hepatico-pancreatico-biliary disease. However, novel endoscopes have also improved diagnostics through direct visualization of the biliary tract and the pancreatic duct, including targeted biopsy-sampling of suspicious endoluminal lesions. The use of cholangioscopy also allows for lithotripsy of complex gallstones under direct visualization. In patients with malignant biliary obstruction, endosonography(EUS)-guided insertion of novel lumen-apposing metal stents allow for extraanatomical access to intra- or extrahepatic bile ducts, if traditional transpapillary stent insertion fails. Especially in patients with altered anatomy e. g., after surgery, EUS-guided transgastric drainage may be the most sensible approach. Using similar techniques, EUS-guided drainage of the pancreatic duct is also possible. Local tumor therapy may be achieved with novel endoscopic retrograde cholangiography-guided catheter-based radiofrequency ablation and photodynamic therapy. In chronic pancreatitis, similar to biliary disease, methods of endoluminal diagnosis, lithotripsy, and transgastric drainage may also be applied. This article provides an overview of novel endoscopic techniques and methods that are available in hepatico-pancreatico-biliary disease.

Abstract
BACKGROUND AND AIMS The BougieCap (Ovesco Endoscopy AG, Tübingen, Germany) is a new device that allows optical and tactile feedback during stricture dilation of the upper GI tract. We evaluated the technical feasibility, clinical efficacy, and safety of a 1-time esophageal stricture dilation using the BougieCap in adults with eosinophilic esophagitis (EoE). METHODS EoE patients prospectively included in the Swiss EoE Cohort were dilated with the BougieCap for esophageal strictures (esophageal diameter, ≤14 mm) and stricture-related symptoms. Symptoms were assessed before and 2 weeks after a single dilation session using the validated Eosinophilic Esophagitis Activity Index Patient Reported Outcomes instrument (score ranges from 0 to 100 points). RESULTS Fifty patients (70% men; median age, 41 years; median disease duration, 4 years; 50% treated with swallowed topical corticosteroids, 10% with proton pump inhibitors, 14% with combined swallowed topical corticosteroids plus proton pump inhibitors, 14% with elimination diet, 12% without antieosinophil therapy) were evaluated. Endoscopic bougienage was technically successful in 100%. The median esophageal diameter increased from 12 mm (interquartile range [IQR], 12-13) to 16 mm (IQR, 16-16; P < .001). Median symptom severity dropped from 32 points (IQR, 27-41) to 0 (IQR, 0-10; P < .001) at 2 weeks postdilation. In 1 patient the BougieCap was temporarily lost after stricture dilation in the hypopharynx but could be retrieved. No severe adverse events were reported. CONCLUSIONS In adults with EoE, endoscopic treatment of esophageal strictures using the BougieCap is technically feasible and safe and offers significant symptomatic improvement in the short term.

Abstract
BACKGROUND Patient care in ulcerative colitis (UC) remains challenging despite an array of established treatment options and emerging new therapies. The management of UC therapy should be guided by the endoscopic extent of inflammation, disease severity, and prognostic factors of poor outcome. Complete remission, defined as durable symptomatic and endoscopic remission without corticosteroid therapy, is the desired treatment goal. SUMMARY This review focuses on treatment recommendations for different clinical scenarios in moderate-to-severe UC: Active UC of any extent not responding to aminosalicylates, steroid-dependent UC, steroid-refractory UC, immunomodulator-refractory UC, and acute severe UC. Comprehensive treatment algorithms for daily clinical practice were developed based on published guidelines and current literature. Key Messages: While current treatment options including a number of biologicals and small molecules have evolved UC treatment to achieve sustained remission in a majority of patients, upcoming treatment options with different molecular pathways and different modes of actions will further increase the need for personalized medicine.

Abstract
BACKGROUND Treatment of Crohn's disease (CD) patients is complex as therapy choices depend on a variety of factors, such as location and severity of inflammation, disease behavior (inflammatory, stricturing or penetrating) but also comorbidities, extra-intestinal manifestations, the patient's age, and previous therapies. Subsequently, the choice of treatment should be tailored to the individual patient. SUMMARY This article gives the reader therapy algorithms as a guide through different CD scenarios to support the physician's decision making. New compounds introduced in CD therapy in recent years justify such an update on standard approaches. Ustekinumab and vedolizumab and their positions within the treatment options are discussed. Fistulizing perianal disease and postoperative medical prophylaxis are depicted in separate chapters with own algorithms. Key Messages: In recent years, a variety of new drugs became available to treat patients with CD - especially those who are antitumor necrosis factor (TNF) experienced with ongoing inflammation. The definitive role of vedolizumab and ustekinumab is not yet fully clarified. However, with the advantage of good safety profiles over TNF-inhibitors, these drugs will be more frequently used in the near future, also as first-line biologicals, compared to TNF-inhibitors. Concerning treatment of fistulizing disease, the knowledge of the exact anatomy of the fistula is of major importance. An interdisciplinary discussion involving gastroenterologists, surgeons, and in some cases gynecologists may help to optimize the treatment plan. Regarding the postsurgical setting in CD patients, according to the very recent Cochrane Network meta-analysis, mesalazine should be at least positioned equivalent to thiopurines and TNF-inhibitors, as shown in our algorithm.

Abstract
Background: Laryngopharyngeal reflux (LPR) can display a variety of symptoms, and upper endoscopy is occasionally used for its investigation. The aim of the present study was to determine the value of transnasal esophagoscopy (TNE) in the workup of LPR. Methods: In 200 consecutive patients with suspected LPR, reflux symptom index (RSI), reflux finding score (RFS), oropharyngeal pH-monitoring (PHM) and transnasal esophagoscopy (TNE) were carried out and rated according to the Horvath Score. Results: In the investigation of LPR, TNE showed a sensitivity, specificity and accuracy of 96%, 85% and 95%, respectively. The most common pathologic TNE findings in LPR patients were an insufficient cardia, hiatal hernia, lymphoid follicles and visible reflux. Conclusions: TNE is a supportive method in the workup of LPR, which can display the underlying pathology and directly affect therapeutic decisions.

Abstract
BACKGROUND Laryngopharyngeal reflux (LPR) is a prevalent disorder. The aim of the present retrospective cohort study was to evaluate oropharyngeal pH-monitoring using a novel scoring system for LPR. METHODS In a total of 180 consecutive patients with possible LPR, reflux symptom index (RSI), reflux finding score (RFS), oropharyngeal pH-monitoring and transnasal esophagoscopy were carried out for further investigation. RESULTS In our series, 99 (55%) patients had severe LPR, 29 (16%) cases presented with moderate and 23 (13%) with mild severity, 9 (5%) subjects revealed neutral values, and 7 (4%) individuals were alkaline, while 13 (7%) patients had no LPR. In detecting LPR, the sensitivity, specificity and accuracy of oropharyngeal pH-monitoring was 95%, 93% and 94%, respectively. CONCLUSION Oropharyngeal pH-monitoring is a reliable tool in the assessment of LPR, but the pH graphs have to be precisely analyzed and interpreted in context with other validated diagnostic tests.

Abstract
OBJECTIVE Although laryngopharyngeal reflux (LPR) is a common condition in daily practice, no gold standard exists for its diagnosis. The objective of this study was to establish a simple and reliable scoring system for evaluating LPR consisting of both subjective and objective criteria. METHODS This retrospective study includes 124 patients presenting with symptoms of LPR. In all patients, reflux symptom index (RSI), reflux finding score (RFS), oropharyngeal pH monitoring (PHM) and transnasal oesophagoscopy (TNE) were performed and rated in a special scoring system. RESULTS A Horvath Score of 4-5 for severe LPR was found in 76 patients (61%), a score of 2-3 for non-severe LPR in 38 patients (31%) and a score of 0-1 for non-existing LPR in 10 patients (8%) by combining the 4 validated diagnostic methods. CONCLUSION The proposed scoring system qualifies as a simple and reliable tool for evaluating LPR in daily practice, directly impacting patient management.

Abstract
BACKGROUND AND AIMS We evaluated the cost-effectiveness of early [≤2 years after diagnosis] compared with late or no biologic initiation [starting biologics >2 years after diagnosis or no biologic use] for adults with Crohn's disease in Switzerland. METHODS We developed a Markov cohort model over the patient's lifetime, from the health system and societal perspectives. Transition probabilities, quality of life, and costs were estimated using real-world data. Propensity score matching was used to ensure comparability between patients in the early [intervention] and late/no [comparator] biologic initiation strategies. The incremental cost-effectiveness ratio [ICER] per quality-adjusted life year [QALY] gained is reported in Swiss francs [CHF]. Sensitivity and scenario analyses were performed. RESULTS Total costs and QALYs were higher for the intervention [CHF384 607; 16.84 QALYs] compared with the comparator [CHF340 800; 16.75 QALYs] strategy, resulting in high ICERs [health system: CHF887 450 per QALY; societal: CHF449 130 per QALY]. In probabilistic sensitivity analysis, assuming a threshold of CHF100 000 per QALY, the probability that the intervention strategy was cost-effective was 0.1 and 0.25 from the health system and societal perspectives, respectively. In addition, ICERs improved when we assumed a 30% reduction in biologic prices [health system: CHF134 502 per QALY; societal: intervention dominant]. CONCLUSIONS Early biologic use was not cost-effective, considering a threshold of CHF100 000 per QALY compared with late/no biologic use. However, early identification of patients likely to need biologics and future drug price reductions through increased availability of biosimilars may improve the cost-effectiveness of an early treatment approach.

Abstract
BACKGROUND Sodium benzoate, a common food preservative, is used in the treatment of patients with urea cycle disorders (UCDs) as it stimulates ammonia removal by a non-urea cycle-based pathway. Despite its use in the clinical routine, no commercially available oral formulations currently exist. Liquid formulation is normally well accepted in pediatric age and allows precise dosage according to the children's needs. AIMS (1) To prepare an oral sodium benzoate solution in different tastes and determine its stability, palatability, and tolerability and (2) to describe the long-term follow-up of two pediatric patients with UCDs treated with our formulation. METHODS We prepared five oral solutions of sodium benzoate (200 mg/ml) by adding different flavoring agents. We measured drug concentration in the samples by high-performance liquid chromatography (HPLC). We evaluated palatability and tolerability with adult volunteers. Long-term drug compliance and metabolic control were appraised in two pediatric patients. RESULTS All the oral solutions remained stable at room temperature along the 96-day test period, and they were well tolerated. The mint-flavored solution resulted the most palatable and preferred by adult volunteers. We report good drug compliance and good metabolic outcomes for both pediatric patients during the entire follow-up. CONCLUSIONS Our study highlighted the stability and tolerability of flavored sodium benzoate oral solutions. These solutions were well accepted during a long-term follow-up and guaranteed a good metabolic control. Since taste attributes are critical to ensure acceptable medication adherence in the pediatric age, flavored liquid formulations of sodium benzoate may be an efficient strategy to achieve therapeutic outcomes in UCD pediatric patients.

Abstract
Biologics are effective and have a good safety profile in the treatment of inflammatory bowel disease. Biosimilars have recently become available as treatment option. They are biological agents that are highly similar to the original biologic compound in their structure, biological activity, efficacy and safety. This position paper summarises current knowledge on biosimilars and presents its statements on regulatory issues and clinical situation in order to provide clinicians adequate information for them to reach informed and appropriate shared decision-making with their patients.

Abstract
BACKGROUND Some patients complain that eating lettuce, gives them gas and abdominal distention. Our aim was to determine to what extent the patients' assertion is sustained by evidence. METHODS An in vitro study measured the amount of gas produced during the process of fermentation by a preparation of human colonic microbiota (n = 3) of predigested lettuce, as compared to beans, a high gas-releasing substrate, to meat, a low gas-releasing substrate, and to a nutrient-free negative control. A clinical study in patients complaining of abdominal distention after eating lettuce (n = 12) measured the amount of intestinal gas and the morphometric configuration of the abdominal cavity in abdominal CT scans during an episode of lettuce-induced distension as compared to basal conditions. KEY RESULTS Gas production by microbiota fermentation of lettuce in vitro was similar to that of meat (P = .44), lower than that of beans (by 78 ± 15%; P < .001) and higher than with the nutrient-free control (by 25 ± 19%; P = .05). Patients complaining of abdominal distension after eating lettuce exhibited an increase in girth (35 ± 3 mm larger than basal; P < .001) without significant increase in colonic gas content (39 ± 4 mL increase; P = .071); abdominal distension was related to a descent of the diaphragm (by 7 ± 3 mm; P = .027) with redistribution of normal abdominal contents. CONCLUSION AND INFERENCES Lettuce is a low gas-releasing substrate for microbiota fermentation and lettuce-induced abdominal distension is produced by an uncoordinated activity of the abdominal walls. Correction of the somatic response might be more effective than the current dietary restriction strategy.

Abstract
Diagnosis and Monitoring of Inflammatory Bowel Disease Abstract. The diagnosis and monitoring of inflammatory bowel disease (IBD) is based on several factors: Clinical history, physical examination, laboratory values (blood and stool), endoscopy, histology and imaging. No single feature establishes the diagnosis alone. In recent years, therapeutic goals in IBD have evolved from clinical endpoints to endoscopic or even histologic targets. However, these targets, e. g. mucosal healing, still have to be uniformly defined. Repeated endoscopies are ill-tolerated by patients, therefore surrogate-markers of mucosal inflammation such as calprotectin, have been investigated and showed good correlation with endoscopic findings. In Crohn's Disease, directing therapy with tight control, based, among others, on fecal calprotectin, has been superior to conventional therapy-monitoring and decision making. However, these initial results need further confirmation. Therapeutic drug monitoring (TDM) has emerged as a second monitoring entity in the long term treatment of IBD patients. Especially with the increasing use of biologics, reactive TDM (in patients who relapse) and to a lesser extent proactive TDM (in patients who are in clinical remission / stable disease) have been studied and results have been adopted in current guidelines. Future studies will have to better define treatment targets and further investigate the impact of tight-monitoring on disease outcome.

Abstract
BACKGROUND ANDAIMS Vitamin and iron deficiencies are common in patients with inflammatory bowel disease (IBD) as a result of chronic intestinal inflammation, increase in demand, or dietary restrictions. Here, we assessed the frequency of complications in relation to deficiency of iron, folate acid, and vitamin B12 in patients enrolled in the nationwide Swiss Inflammatory Bowel Disease Cohort Study (SIBDCS). METHODS A total of 2666 patients were included in the study, 1558 with Crohn's disease (CD) and 1108 with ulcerative colitis (UC). RESULTS Iron deficiency anemia was detected in 19.6% of CD patients and 21.6% of UC patients. In CD patients low BMI and nonsmoker status were positively associated with anemia. In both CD and UC, malabsorption syndrome, defined as failure of the GI tract to absorb 1 or more substances from the diet, was found to be significantly associated with anemia (6.2% and 3.8%, respectively) and current steroid use (40% CD, 52.7% UC). In CD patients with ileal (31.7% vs 20%) and colonic (29.9% vs 25%) disease location folate deficiency was significantly higher than in patients with ileocolonic CD or upper GI involvement. In CD patients, vitamin B12 deficiency was associated with the onset of stenosis and intestinal surgery (42.9% vs 32.8% and 46% vs 33% for patients with versus without B12 deficiency). CONCLUSION Our data indicate that due to frequent occurrence of deficiency states, regular monitoring and substitution of vitamins and iron are mandatory and may prevent long-term intestinal and extraintestinal complications in IBD patients.

Abstract
Background Faecal calprotectin correlates with histological and clinical activity in inflammatory bowel disease. Gastrointestinal bleeding might also increase faecal calprotectin levels, erroneously implying intestinal inflammation; however, this possibility has not been systematically assessed. Methods Sixteen healthy volunteers without gastrointestinal disease and normal faecal calprotectin baseline values ingested their own blood twice, either by drinking or via nasogastric tube. Quantities of 100 ml and 300 ml blood were ingested in a randomised order, with a 28-day wash-out period. Faecal calprotectin, faecal occult blood test, and the occurrence of melaena were assessed. Faecal calprotectin ≥ 50 µg/g was considered elevated. Results Melaena was reported by all healthy volunteers after 300 ml and by 11/15 healthy volunteers (71%) after 100 ml blood ingestion. One day after ingestion of 300 ml blood, 8/16 faecal calprotectin tests were positive compared to 1/16 at baseline (p = 0.016). Faecal calprotectin levels above > 200 µg/g were rarely observed. There was a trend for faecal calprotectin test positivity also after ingestion of 100 ml. Conclusion Ingestion of blood resulted in an increase in faecal calprotectin-positive tests. Gastrointestinal bleeding should be considered as a potential cause of mild faecal calprotectin elevation > 50 µg/g; however, increased faecal calprotectin above > 250-300 µg/g, the established cut-off for relevant intestinal inflammation in patients with inflammatory bowel disease, is rare.

Abstract
BACKGROUND Gut content may be determinant in the generation of digestive symptoms, particularly in patients with impaired gut function and hypersensitivity. Since the relation of intraluminal gas to symptoms is only partial, we hypothesized that non-gaseous component may play a decisive role. METHODS Abdominal computed tomography scans were evaluated in healthy subjects during fasting and after a meal (n = 15) and in patients with functional gut disorders during basal conditions (when they were feeling well) and during an episode of abdominal distension (n = 15). Colonic content and distribution were measured by an original analysis program. KEY RESULTS In healthy subjects both gaseous (87 ± 24 mL) and non-gaseous colonic content (714 ± 34 mL) were uniformly distributed along the colon. In the early postprandial period gas volume increased (by 46 ± 23 mL), but non-gaseous content did not, although a partial caudad displacement from the descending to the pelvic colon was observed. No differences in colonic content were detected between patients and healthy subjects. Symptoms were associated with discrete increments in gas volume. However, no consistent differences in non-gaseous content were detected in patients between asymptomatic periods and during episodes of abdominal distension. CONCLUSIONS & INFERENCES In patients with functional gut disorders, abdominal distension is not related to changes in non-gaseous colonic content. Hence, other factors, such as intestinal hypersensitivity and poor tolerance of small increases in luminal gas may be involved.

Abstract
BACKGROUND & AIMS We examined the relationship between symptoms of depression and anxiety and clinical recurrence of inflammatory bowel disease (IBD) in a large patient cohort. We considered the progression of depression and anxiety over time. METHODS We collected clinical and treatment data on 2007 adult participants of the Swiss IBD study (56% with Crohn's disease [CD], 48% male) performed in Switzerland from 2006 through 2015. Depression and anxiety symptoms were quantified by using the Hospital Anxiety and Depression Scale. The relationship between depression and anxiety scores and clinical recurrence was analyzed by using survival-time techniques. RESULTS We found a significant association between symptoms of depression and clinical recurrence over time (for all patients with IBD, P = .000001; for subjects with CD, P = .0007; for subjects with ulcerative colitis, P = .005). There was also a significant relationship between symptoms of anxiety and clinical recurrence over time in all subjects with IBD (P = .0014) and in subjects with CD (P = .031) but not ulcerative colitis (P = .066). CONCLUSIONS In an analysis of a large cohort of subjects with IBD, we found a significant association between symptoms of depression or anxiety and clinical recurrence. Patients with IBD should therefore be screened for clinically relevant levels of depression and anxiety and referred to psychologists or psychiatrists for further evaluation and treatment.

Abstract
BACKGROUND The precise relation of intestinal gas to symptoms, particularly abdominal bloating and distension remains incompletely elucidated. Our aim was to define the normal values of intestinal gas volume and distribution and to identify abnormalities in relation to functional-type symptoms. METHODS Abdominal computed tomography scans were evaluated in healthy subjects (n = 37) and in patients in three conditions: basal (when they were feeling well; n = 88), during an episode of abdominal distension (n = 82) and after a challenge diet (n = 24). Intestinal gas content and distribution were measured by an original analysis program. Identification of patients outside the normal range was performed by machine learning techniques (one-class classifier). Results are expressed as median (IQR) or mean ± SE, as appropriate. KEY RESULTS In healthy subjects the gut contained 95 (71, 141) mL gas distributed along the entire lumen. No differences were detected between patients studied under asymptomatic basal conditions and healthy subjects. However, either during a spontaneous bloating episode or once challenged with a flatulogenic diet, luminal gas was found to be increased and/or abnormally distributed in about one-fourth of the patients. These patients detected outside the normal range by the classifier exhibited a significantly greater number of abnormal features than those within the normal range (3.7 ± 0.4 vs 0.4 ± 0.1; p < 0.001). CONCLUSIONS & INFERENCES The analysis of a large cohort of subjects using original techniques provides unique and heretofore unavailable information on the volume and distribution of intestinal gas in normal conditions and in relation to functional gastrointestinal symptoms.

Abstract
BACKGROUND & AIMS In patients with functional gut disorders, abdominal distension has been associated with descent of the diaphragm and protrusion of the anterior abdominal wall. We investigated mechanisms of abdominal distension in these patients. METHODS We performed a prospective study of 45 patients (42 women, 24-71 years old) with functional intestinal disorders (27 with irritable bowel syndrome with constipation, 15 with functional bloating, and 3 with irritable bowel syndrome with alternating bowel habits) and discrete episodes of visible abdominal distension. Subjects were assessed by abdominothoracic computed tomography (n = 39) and electromyography (EMG) of the abdominothoracic wall (n = 32) during basal conditions (without abdominal distension) and during episodes of severe abdominal distension. Fifteen patients received a median of 2 sessions (range, 1-3 sessions) of EMG-guided, respiratory-targeted biofeedback treatment; 11 received 1 control session before treatment. RESULTS Episodes of abdominal distension were associated with diaphragm contraction (19% ± 3% increase in EMG score and 12 ± 2 mm descent; P < .001 vs basal values) and intercostal contraction (14% ± 3% increase in EMG scores and 6 ± 1 mm increase in thoracic antero-posterior diameter; P < .001 vs basal values). They were also associated with increases in lung volume (501 ± 93 mL; P < .001 vs basal value) and anterior abdominal wall protrusion (32 ± 3 mm increase in girth; P < .001 vs basal). Biofeedback treatment, but not control sessions, reduced the activity of the intercostal muscles (by 19% ± 2%) and the diaphragm (by 18% ± 4%), activated the internal oblique muscles (by 52% ± 13%), and reduced girth (by 25 ± 3 mm) (P ≤ .009 vs pretreatment for all). CONCLUSIONS In patients with functional gut disorders, abdominal distension is a behavioral response that involves activity of the abdominothoracic wall. This distension can be reduced with EMG-guided, respiratory-targeted biofeedback therapy.

Abstract
BACKGROUND Non-invasive monitoring of inflammatory bowel disease is an unmet clinical need as patients in clinical remission may have residual mucosal inflammation preceding clinical relapse. AIMS We aimed to assess the value of fecal calprotectin and standardized clinical activity scoring to monitor disease activity in ulcerative colitis under medical treatment. METHODS Forty-one patients with ulcerative colitis were included in a prospective observational study. Medical treatment was guided by clinical judgement of treating physicians. Fecal calprotectin and the clinical activity index (CAI) were measured blinded to treating physicians every 2 months until the end of follow-up. Twenty-six patients received colonoscopy for clinical reason. RESULTS As defined by the CAI, patients were in clinical remission (63.4 %), having mild (26.8 %) or moderate (11.2 %) disease activity. Of those in clinical remission (CAI ≤ 4), 86.4 % showed residual endoscopic activity (Mayo Score ≥1). Calprotectin levels were higher in endoscopically active disease (779.0 vs 331.5 μg/g, P = 0.034) and calprotectin testing identified more patients with endoscopic disease activity (86.4 %) than the CAI (45.5 %, P = 0.034). Medical treatment was escalated in 90.2 % during the study. Values of the CAI and calprotectin correlated with therapy escalation (OR 3.94 and 3.22, respectively). Only for calprotectin, changes between two measurements were related to intensified medical treatment (OR 1.39). CONCLUSION Fecal calprotectin was similarly useful to the CAI to monitor disease activity of ulcerative colitis during medical treatment but identified endoscopic disease activity far more reliably. Changes of calprotectin values between measurements might indicate clinical relapse earlier than the CAI.

Abstract
Crohn's disease and ulcerative colitis are characterized by periods of symptomatic relapse and remission. Diagnosis and assessment of inflammatory bowel disease has so far been based on clinical evaluation, serum parameters, radiology and endoscopy. Faecal markers such as calprotectin or lactoferrin have emerged as new diagnostic tools to detect and monitor intestinal inflammation. This review focuses on their potential clinical applications and limitations in the management of inflammatory bowel disease.

Abstract
BACKGROUND & AIMS Rumination syndrome is characterized by effortless recurrent regurgitation of recently ingested food into the mouth, with consequent expulsion or re-chewing and swallowing. We investigated whether rumination is under volitional control and can be reversed by behavioral treatment. METHODS We performed a prospective study of 28 patients who fulfilled the Rome criteria for rumination and had no organic disorders on the basis of a thorough evaluation. The diagnosis of rumination was confirmed by intestinal manometry (abdominal compression associated with regurgitation). Patients were trained to modulate abdominothoracic muscle activity under visual control of electromyographic recordings. Recordings were made after challenge meals, before training (baseline), and during 3 treatment sessions. Outcome was measured by questionnaires administered daily for 10 days before training, immediately after training, and at 1, 3, and 6 months after training. RESULTS By the end of the 3 sessions, patients had effectively learned to reduce intercostal activity (by 50% ± 2%; P < .001 vs basal) and anterior wall muscle activity (by 30% ± 6%; P < .001 vs basal). Patients reported 27 ± 1 regurgitation episodes/day at baseline and 8 ± 2 episodes/day immediately after treatment. Regurgitation episodes decreased further to 4 ± 1 episodes at 6 months after training. CONCLUSIONS Rumination is produced by an unperceived somatic response to food ingestion that disrupts abdominal accommodation and can be effectively corrected by biofeedback-guided control of abdominothoracic muscular activity.

Abstract
BACKGROUND In recent years several trials have addressed treatment challenges in Crohn's disease. Clinical trials however, represent a very special situation. AIMS To perform a cross-sectional survey among gastroenterologists on the current clinical real life therapeutic approach focussing on the use of biologics. METHODS A survey including six main questions on clinical management of loss of response, diagnostic evaluation prior to major treatment changes, preference for anti-tumour necrosis factor (TNF) agent, (de-)escalation strategies as well as a basic section regarding personal information was sent by mail to all gastroenterologists in Switzerland (n=318). RESULTS In total, 120 questionnaires were analysed (response rate 37.7%). 90% of gastroenterologists in Switzerland use a thiopurine as the first step-up strategy (anti-TNF alone 7.5%, combination 2.5%). To address loss of response, most physicians prefer shortening the interval of anti-TNF administration followed by dose increase, switching the biologic and adding a thiopurine. In case of prolonged remission on combination therapy, the thiopurine is stopped first (52.6%) after a mean treatment duration of 15.7 months (biologic first in 41.4%). CONCLUSIONS Everyday clinical practice in Crohn's disease patients appears to be incongruent with clinical data derived from major trials. Studies investigating reasons underlying these discrepancies are of need to optimize and harmonize treatment.

Abstract
Measurement of faecal calprotectin concentration is increasingly used to assess disease activity in patients with IBD. Lasson et al. have now demonstrated that calprotectin concentrations in faeces of patients with mild or moderate left-sided or extensive ulcerative colitis vary considerably and have questioned the long-term stability of calprotectin when stored at room temperature.

Abstract
BACKGROUND European Panel on the Appropriateness of Gastrointestinal Endoscopy (EPAGE) criteria have been developed to increase diagnostic yield, but their predictive value is limited. We investigated the incremental diagnostic value of faecal calprotectin to EPAGE criteria. METHODS In a post-hoc analysis of a prospective study, EPAGE criteria were applied to 298 of 575 (51.8%) patients who had undergone esophagogastroduodenoscopy (EGD), colonoscopy or both for abdominal complaints at the Division of Gastroenterology & Hepatology at the University Hospital Basel in Switzerland. Faecal calprotectin was measured in stool samples collected within 24 hours before the investigation using an enzyme-linked immunosorbent assay. Final endoscopic diagnoses were blinded to calprotectin values. RESULTS Of 149 EGDs and 224 colonoscopies, 17.6% and 14.7% respectively were judged inappropriate by EPAGE criteria. Appropriate or uncertain indications revealed more endoscopic findings in both EGD (46.3% vs. 23.1%, P = 0.049) and colonoscopy (23.6% vs. 6.1%, P = 0.041) than inappropriate indications. Median calprotectin levels were higher (81.5 μg/g, interquartile range 26-175, vs. 10 μg/g, IQR 10-22, P < 0.001) and testing was more often positive (>50 μg/g) in patients with endoscopic findings, both in EGD (58.2% vs. 33.0%, P = 0.005) and in colonoscopy (57.3% vs. 7.4%, P < 0.001). The use of faecal calprotectin in addition to EPAGE criteria improved the risk reclassification of patients by endoscopic findings. The calculated net reclassification index was 37.8% (P = 0.002) for EGD and 110.9% (P <0.001) for colonoscopy, thus improving diagnostic yield to 56.8% and 70.2%, respectively. CONCLUSIONS The use of faecal calprotectin in addition to EPAGE criteria improved diagnostic yield in patients with abdominal complaints.

Abstract
OBJECTIVE Patients with irritable bowel syndrome and abdominal bloating exhibit abnormal responses of the abdominal wall to colonic gas loads. We hypothesised that in patients with postprandial bloating, ingestion of a meal triggers comparable abdominal wall dyssynergia. Our aim was to characterise abdominal accommodation to a meal in patients with postprandial bloating. DESIGN A test meal (0.8 kcal/ml nutrients plus 27 g/litre polyethylenglycol 4000) was administered at 50 ml/min as long as tolerated in 10 patients with postprandial bloating (fulfilling Rome III criteria for postprandial distress syndrome) and 12 healthy subjects, while electromyographic (EMG) responses of the anterior wall (upper and lower rectus, external and internal oblique via bipolar surface electrodes) and the diaphragm (via six ring electrodes over an oesophageal tube in the hiatus) were measured. Means +/- SD were calculated. RESULTS Healthy subjects tolerated a meal volume of 913±308 ml; normal abdominal wall accommodation to the meal consisted of diaphragmatic relaxation (EMG activity decreased by 15±6%) and a compensatory contraction (25±9% increase) of the upper abdominal wall muscles (upper rectus and external oblique), with no changes in the lower anterior muscles (lower rectus and internal oblique). Patients tolerated lower volume loads (604±310 ml; p=0.030 vs healthy subjects) and developed a paradoxical response, that is, diaphragmatic contraction (14±3% EMG increment; p<0.01 vs healthy subjects) and upper anterior wall relaxation (9±4% inhibition; p<0.01 vs healthy subjects). CONCLUSIONS In functional dyspepsia, postprandial abdominal distension is produced by an abnormal viscerosomatic response to meal ingestion that alters normal abdominal accommodation.

Abstract
Abdominal discomfort including pain, bloating and diarrhea is common. It often arises from functional gastrointestinal disorders but may indicate inflammatory bowel disease (IBD). Calprotectin is an abundant neutrophil protein that is released during inflammation. When measured in feces, it can be used to differentiate between non-organic and inflammatory intestinal disorders, especially to identify IBD. Fecal calprotectin might also be useful to monitor patients with IBD under treatment and to predict the risk of recurrence of active disease prior to clinical relapse. The use of fecal calprotectin has been investigated in a number of gastrointestinal disorders other than IBD, for example, as screening test for colorectal cancer but the available data are limited. This article summarizes the current literature on the use of fecal calprotectin in clinical practice.

Abstract
In patients with Crohn's disease, perianal lesions can be found at presentation in 20 - 30 % of all cases and a majority will have fistulas or abscesses. If a fistula is suspected, careful inspection of the perianal region will often confirm the diagnosis. Further investigation should be done by magnet-resonance imaging or anal endosonography to guide preoperative planing and minimize recurrence rates. Simple, uncomplicated fistulas are primarily treated with antibiotics. For complex fistulas combined with medication and surgical treatment usually offers the best treatment. Treatment of complex fistulas by surgery alone is rarely curative and may have significant morbidity, while medical treatment has the disadvantage of high recurrence rates and significant costs for long-term therapy. In trans-, supra- and extrasphincteric fistulas, immunosuppressants or anti-TNF alpha blockers will lead to sustained clinical remission with fistula closure in 30 - 50 %. However, 25 % of all patients with perianal Croh's disease will still need surgery during the course of their disease. Fistulotomy is used for subcutaneous or short intersphincteric fistulas while it should be avoided in fistulas with significant involvmenet of the sphincter muscles to avoid fecal incontinence. Seton drainage may be used as definitve treatment or as a bridge to a secondary surgical therapy. Minimally invasive precedures, such as the anal fistula plug have also been used in Crohn's disease. Although recurrence rates are high, the procedure is easy to perform and carries a low risk of incontinence and may therefore be used as primary treatment option for complex fistulas. The fistulectomy and closure of the inner fistula opening, e. g. with a mucosal advancement flap, is still considered the standard procedure, especially for complex fistulas. Anal fissures, ulcers and strictures are non-fistulating perianal lesions of Crohn's disease.

Abstract
BACKGROUND We previously showed that abdominal distension in patients with functional gut disorders is due to a paradoxical diaphragmatic contraction without major increment in intraabdominal volume. Our aim was to characterize the pattern of gas retention and the abdomino-thoracic mechanics associated with abdominal distension in patients with intestinal dysmotility. METHODS In 15 patients with manometrically proven intestinal dysmotility, two abdominal CT scans were performed: one during basal conditions and other during an episode of severe abdominal distension. In 15 gender- and age-matched healthy controls, a basal scan was performed. KEY RESULTS In basal conditions, patients exhibited more abdominal gas than healthy subjects, particularly in the small bowel, and the volume significantly increased during an episode of distension. During episodes of abdominal distension, the increase in abdominal content was associated with increased girth and antero-posterior abdominal diameter, as well as a cephalic displacement of the diaphragm, which reduced the height of the lung. The consequent reduction in the air volume of the lung was attenuated by an increase in the antero-posterior diameter of the chest. CONCLUSIONS & INFERENCES Abdominal distension in patients with severe intestinal dysfunction is related to marked pooling of gut contents, particularly in the small bowel. This increase in content is accommodated within the abdominal cavity by a global and coordinated abdomino-phreno-thoracic response, involving an accommodative ascent of the diaphragm and a compensatory expansion of the chest wall.

Abstract
AIM: To evaluate the diagnostic capability of calprotectin in ascitic fluid for detecting a polymorphonuclear (PMN) cell count > 250/μL ascites.
METHODS: In this prospective observational study, a total of 130 ascites samples were analysed from 71 consecutive patients referred for paracentesis. Total and differential leukocyte cell counts were determined manually with a Neubauer chamber and gentian-violet stain. Calprotectin was measured in 1 mL ascetic fluid by enzyme-linked immunosorbent assay (ELISA) and a point-of-care (POC) lateral flow assay with the Quantum Blue® Reader (Bühlmann Laboratories). All measurements were carried out in a central laboratory by senior personnel blinded to patient history. A PMN count > 250/μL was the primary endpoint of the study. The diagnostic value of ascitic calprotectin measurement was assessed by comparing to the final diagnosis of each patient that had been adjudicated by investigators blinded to calprotectin values.
RESULTS: The PMN count was > 250/μL in 19 samples (14.6%) from 15 patients (21.1%) and varied widely among the study population (range 10-19 800/mL and 1-17 820/mL, respectively). Spontaneous bacterial peritonitis (SBP) was the final diagnosis in four patients (5.6%). All patients with PMN ≤ 250/μL had negative bacterial culture. PMN count was elevated in five patients with peritoneal carcinomatosis, three with lymphoma, one with neuroendocrine carcinoma, and two with secondary peritonitis due to abdominal perforation. PMN cell counts correlated with ascitic calprotectin values (Spearman’s rho; r = 0.457 for ELISA, r = 0.473 for POC). A considerable range of ascitic calprotectin concentrations was detected by ELISA [median 0.43 μg/mL, interquartile range (IQR) 0.23-1.23 (range 0.10-14.93)] and POC [median 0.38 μg/mL, IQR 0.38-0.56 (range 0.38-13.31)]. Ascitic calprotectin levels were higher in samples with PMN > 250/μL, by both ELISA [median (IQR) 2.48 μg/mL (1.61-3.65) vs 0.10 μg/mL (0.10-0.36), P < 0.001] and POC [2.78 μg/mL (2.05-5.37) vs 0.38 μg/mL (0.38-0.41), P < 0.001]. The area under the receiver operating characteristics curve for identifying an elevated PMN count was 0.977 (95%CI: 0.933 to 0.995) for ELISA and 0.982 (95%CI: 0.942 to 0.997) for POC (P = 0.246 vs ELISA). Using the optimal cut-off value for ELISA (0.63 μg/mL), ascitic calprotectin had 94.8% sensitivity, 89.2% specificity, positive and negative likelihood ratios of 8.76 and 0.06 respectively, positive and negative predictive values of 60.0% and 99.0% respectively, and 90.0% overall accuracy. Using the optimal cut-off value for POC (0.51 μg/mL), the respective values were 100.0%, 84.7%, 6.53, 0.00, 52.8%, 100% and 87.7%. Correlation between ELISA and POC was excellent (r = 0.873, P < 0.001). The mean ± SD of the difference was -0.11 ± 0.48 μg/mL with limits of agreement of + 0.8 μg/mL (95%CI: 0.69 to 0.98) and -1.1 μg/mL (95%CI: -1.19 to -0.91).
CONCLUSION: Ascitic calprotectin reliably predicts PMN count > 250/μL, which may prove useful in the diagnosis of SBP, especially with a readily available bedside testing device.

Abstract
BACKGROUND Using an experimental model of colonic gas infusion, we previously showed that the abdominal walls adapt to its content by an active phenomenon of abdominal accommodation. We now hypothesized that abdominal accommodation is a physiological phenomenon, and aimed to confirm that it can be induced by ingestion of a meal; a secondary aim was to determine whether the response to gut filling is region-specific. METHODS In healthy subjects (n = 24) a nutrient test meal was administered until tolerated at a rate of 50 mL min(-1). Electromyographic (EMG) activity of the anterior wall (upper and lower rectus, external and internal oblique) was measured via four pairs of surface electrodes, and EMG activity of the diaphragm via intraluminal electrodes on an esophageal tube. To address the secondary aim, the response to gastric filling was compared with that induced by colonic filling (1440 mL 30 min(-1) anal gas infusion; n = 8). KEY RESULTS Participants tolerated 927 ± 66 mL of meal (450-1500 mL). Meal ingestion induced progressive diaphragmatic relaxation (EMG reduction by 16 ± 2%; P < 0.01) and selective contraction of the upper abdominal wall (24 ± 2% increase in activity of the upper rectus and external oblique; P < 0.01 for both), with no significant changes in the lower rectus (4 ± 2%) or internal oblique (5 ± 3%). Colonic gas infusion induced a similar response, but with an overall contraction of the anterior wall. CONCLUSIONS & INFERENCES Meal ingestion induces a metered and region-specific response of the abdominal walls to accommodate the volume load. Abnormal abdominal accommodation could be involved in postprandial bloating.

Abstract
The monitoring of inflammatory bowel disease (IBD) based on clinical symptoms and activity scores alone has major drawbacks. Despite clinical remission, in many patients with ongoing low-grade inflammation and activity scores, there is a tendency to underestimate IBD activity as parameters depend on the subjective symptoms of the patients. C-reactive protein might identify patients with low-grade inflammation, especially in Crohn's disease, but sensitivity remains limited. Recently, fecal markers of inflammation have been shown to correlate well with endoscopic disease activity and to predict relapse. However, data on serial measurements to guide therapy are scarce. The role of anti-TNF-α antibodies and plasma TNF-α concentrations in IBD therapy is currently unclear and needs to be defined further. The goal of improving disease outcome has not been demonstrated for any noninvasive biomarker so far.

Abstract
BACKGROUND AND AIMS Fecal calprotectin and lactoferrin are sensitive markers of mucosal inflammation. We compared three different assays in their ability to identify patients with organic intestinal disease. METHODS In a post-hoc analysis of a prospective study, we examined 405 unselected patients with abdominal complaints referred for endoscopy to the University Hospital Basel, Switzerland. Calprotectin (EK-CAL, Bühlmann Laboratories, Switzerland; PhiCal, Calpro AS, Norway) and lactoferrin (IBD-Scan, Techlab, USA) were measured using enzyme-linked immunosorbent assays. The presence of a clinically significant endoscopic finding was the primary endpoint of the study. Final diagnoses were adjudicated blinded to calprotectin values. RESULTS The prevalence of organic intestinal disease was 35.3%. Receiver operating characteristics analysis calculated an area under the curve (AUC) for EK-CAL of 0.918, which was significantly better than for PhiCal (AUC 0.842, P<0.001) and IBD-Scan (AUC 0.830, P=0.003) to identify patients with organic intestinal disease. Overall test accuracy was 88.1% for EK-CAL, 83.7% for PhiCal, and 81.3% for IBD-Scan. Optimal cut-off value calculated for PhiCal and IBD-Scan were lower than recommended by the manufacturer. CONCLUSIONS Monoclonal testing of calprotectin is superior to both polyclonal calprotectin testing and fecal lactoferrin in identifying symptomatic patients with organic intestinal disease.

Abstract
OBJECTIVES The rapid and accurate diagnosis of heart failure in primary care is a major unmet clinical need. We evaluated the additional use of B-type natriuretic peptide (BNP) levels. DESIGN A randomized controlled trial. SETTING Twenty-nine primary care physicians in Switzerland and Germany coordinated by the University Hospital Basel, Switzerland. SUBJECTS A total of 323 consecutive patients presenting with dyspnoea. INTERVENTIONS Assignment in a 1 : 1 ratio to a diagnostic strategy including point-of-care measurement of BNP (n = 163) or standard assessment without BNP (n = 160). The total medical cost at 3 months was the primary end-point. Secondary end-points were diagnostic certainty, time to appropriate therapy, functional capacity, hospitalization and mortality. The final diagnosis was adjudicated by a physician blinded to the BNP levels. RESULTS Heart failure was the final diagnosis in 34% of patients. The number of hospitalizations, functional status and total medical cost at 3 months [median $1655, interquartile range (IQR), 850-3331 vs. $1541, IQR 859-2827; P = 0.68] were similar in both groups. BNP increased diagnostic certainty as defined by the need for further diagnostic work-up (33% vs. 45%; P = 0.02) and accelerated the initiation of the appropriate treatment (13 days vs. 25 days; P = 0.01). The area under the receiver-operating characteristics curve for BNP to identify heart failure was 0.87 (95% confidence interval, 0.81-0.93). CONCLUSIONS The use of BNP levels in primary care did not reduce total medical cost, but improved some of the secondary end-points including diagnostic certainty and time to initiation of appropriate treatment.

Abstract
Suspicion of inflammatory bowel disease should be raised in any patient with chronic or recurrent abdominal pain and diarrhoea. However, symptoms of inflammatory bowel disease (IBD) overlap with functional gastrointestinal disorders and those patients may not need endoscopy. Currently, colonoscopy with multiple biopsies is considered the gold standard to establish the diagnosis of IBD. Unfortunately, patient selection for endoscopy based on symptoms is not reliable. The use of guidelines of appropriateness for endoscopy yields significantly more significant findings but the selection criteria suffer from low specificity. Calprotectin is a calcium binding protein of neutrophil granulocytes that correlates well with neutrophil infiltration of the intestinal mucosa when measured in faeces. In the last decade, a large body of evidence on the diagnostic value of faecal calprotectin has accumulated and measurement of calprotectin in faeces has been suggested as a surrogate marker of intestinal inflammation. Testing of faecal calprotectin has been highly useful to distinguish organic from functional intestinal disorders in patients with abdominal complaints. Additionally, faecal calprotectin has reliably identified colonic inflammation in patients with suspected IBD. The use of this inexpensive and widely available test in the evaluation and risk stratification in patients with abdominal complaints is likely to increase in the future.
