The immune cellular landscape from the gastric mucosa remains largely unknown despite its relevance in several inflammatory conditions. Human gastric biopsies were obtained from the antrum, body and incisura from 10 individuals to obtain lamina propria mononuclear cells that were further characterized by spectral cytometry. Phenotypic hierarchical analyses identified a total of 52 different immune cell subsets within the human gastric mucosa revealing that T-cells (> 60%) and NK cells (> 20%) were the main populations.

Coeliac disease is a common condition for which the only current treatment is a gluten-free diet. Adherence to this diet is not always easy and is associated with a reduction in quality of life for the patient and their family. Non-adherence is associated with complications of varying severity.

Background: Intraepithelial lymphocytes are the first line of defence of the human intestinal immune system. Besides, their composition is altered on patients with coeliac disease (CD), so they are considered as biomarkers with utility on their diagnose and/or monitoring. Our aim is to address their variability through the human gastrointestinal tract in health and characterized them in further depth in the coeliac duodenum.

Background And Aims: Familial inflammatory bowel disease (IBD) history is a controversial prognostic factor in IBD. We aimed to evaluate the impact of a familial history of IBD on the use of medical and surgical treatments in the biological era.

Methods: Patients included in the prospectively maintained ENEIDA database and diagnosed with IBD after 2005 were included.

Article Synopsis
  • Markers for personalized treatment options for patients with inflammatory bowel diseases (IBD) remain unidentified, prompting a study on real-life treatment trends.
  • The study analyzed data from 10,009 patients from the ENEIDA registry, revealing that anti-TNF drugs were the most commonly used first-line treatments, but their usage declined over time in Crohn's disease (CD) while remaining stable in ulcerative colitis (UC).
  • Despite exploring Machine Learning for treatment pattern prediction, researchers found that these models were ineffective, indicating distinct treatment approaches for CD and UC and highlighting the rising importance of drugs like ustekinumab and vedolizumab.

A 76-year-old patient, admitted to the department of cardiac surgery, anticoagulated, started with acute dysphagia. An upper endoscopy revealed a blue mucosa from the upper to distal esophagus, with narrowing of the lumen caused by an extrinsic compression. A computed to¬mography (CT) of the thorax was performed, showing a 85x55 mm mediastinal hematoma causing extrinsic compression of the esophagus.

A 69-year-old male, three years post-endovascular exclusion for an abdominal aortic aneurysm, presented with asthenia and fever. An abdominal CT scan showed no gastrointestinal tract communications, abscess, or contrast extravasation. Tc-99m-HMPAO-labeled leukocytes scintigraphy with SPECT/CT revealed increased uptake on the posterior surface of the aortic graft, along with air bubbles in its right iliac limb.

Article Synopsis
  • - The management of Helicobacter pylori infection involves a combination of proton pump inhibitors (PPIs) and antibiotics to effectively eradicate the bacteria, as evaluated by the European Registry on Helicobacter pylori management (Hp-EuReg).
  • - Analysis of data from 36,579 patients across five countries revealed that 14-day treatments with specific antibiotic combinations and high-dose PPIs resulted in optimal effectiveness, while 10- and 14-day therapies with high-dose PPIs were also successful.
  • - The study concludes that for first-line treatment, the use of high-dose PPIs is recommended, especially in certain combinations and durations, while shorter 7-day therapies showed suboptimal results.

•The incidence of early-onset colorectal cancer (EO-CRC) has significantly increased worldwide, often leading to advanced disease at the time of diagnosis. •This study investigates the clinicopathological characteristics of EO-CRC cases at an academic healthcare center in Spain. •The majority of patients with EO-CRC were diagnosed between 40-49 years of age.

Dendritic cells and macrophages are the main antigen-presenting cells (APC). In the gut, they control the mechanisms of tolerance toward commensals and nutrients, at the time that they maintain their capacity to trigger immune responses against invading pathogens. Nevertheless, this balance is not perfect as it can get disrupted like in inflammatory bowel disease (where they drive an abnormal immune response against the microbiota) or in coeliac disease (where they trigger an immune response against dietary gluten).

Introduction: the C-reactive protein (CRP) to albumin ratio is an inflammatory marker that has shown promise in the prognosis of critically ill patients. This study is aimed to assess the value of CRP/albumin ratio to predict severity in acute pancreatitis.

Methods: a retrospective study was performed using a prospectively collected database of patients diagnosed with AP admitted to the Department of Gastroenterology between March 2014 and December 2021.

Background And Aims: Inflammatory bowel disease (IBD) is a prevalent chronic noncurable disease associated with profound metabolic changes. The discovery of novel molecular indicators for unraveling IBD etiopathogenesis and the diagnosis and prognosis of IBD is therefore pivotal. We sought to determine the distinctive metabolic signatures from the different IBD subgroups before treatment initiation.

Article Synopsis
  • A study evaluated the effectiveness and safety of single capsule bismuth quadruple therapy (scBQT) administered three times a day, as opposed to the recommended four times a day schedule, focusing on ease of adherence.
  • Out of 3,712 cases analyzed, the three times a day regimen showed a higher cure rate of 94% compared to 91% for the four times a day schedule, though adherence and safety were similar.
  • The findings suggest that the three times a day scBQT regimen is more effective, with factors like treatment adherence and the type of proton pump inhibitor used being significant predictors of infection cure.

Rates of new dysplastic lesions or cancer progression after first dye chromoendoscopy in the era of high-definition endoscopy have yet to be determined.  A multicenter, population-based, retrospective cohort study was performed in seven hospitals in Spain. Patients with inflammatory bowel disease and fully resected (R0) dysplastic colon lesions under surveillance with high-definition dye-based chromoendoscopy were sequentially enrolled between February 2011 and June 2017, with a minimum endoscopic follow-up of 36 months.

Article Synopsis
  • Breath tests using glucose, lactulose, or lactitol help diagnose small intestinal bacterial overgrowth (SIBO), but they often lack accuracy, leading to incorrect positives in irritable bowel syndrome (IBS) patients.
  • The rise in SIBO diagnoses is attributed to the challenges in managing functional intestinal disorders and the availability of these tests.
  • The study investigates the relationship between plasmatic levels of Intestinal Fatty-Acid Binding protein (I-FABP) in patients undergoing lactitol testing for SIBO and their clinical characteristics and test outcomes, addressing its potential as a marker for early intestinal damage.

The stool antigen test (SAT) represents an attractive alternative for detection of Helicobacter pylori. The aim of this study was to assess the accuracy of a new SAT, the automated LIAISON® Meridian H. pylori SA based on monoclonal antibodies, compared to the defined gold standard 13C-urea breath test (UBT).

Background: Randomized clinical trials and meta-analyses, primarily from Asian countries, have reported good effectiveness with high-dose dual therapy (HDDT) including a proton pump inhibitor (PPI) and amoxicillin when prescribed as first-line or rescue treatment. However, combining amoxicillin with PPIs in the 1990s in several European countries yielded suboptimal results.

Methods: An international, multicenter, prospective non-interventional Registry (Hp-EuReg) aimed to evaluate the decisions and outcomes of management by European gastroenterologists.
