Resolution of dysphagia due to secondary achalasia with neuropathic chronic intestinal pseudo-obstruction by peroral endoscopic myotomy.

Chronic intestinal pseudo-obstruction (CIPO) is a rare condition affecting the motility of the lower gastrointestinal tract, while achalasia is an uncommon esophageal motility disorder. The coexistence of both conditions is extremely rare. We present the case of a patient who had both pathologies, admitted for dysphagia and oral intolerance, the symptoms finally resolved by performing a POEM.

Proton pump inhibitor effect on esophageal protein signature of eosinophilic esophagitis, prediction, and evaluation of treatment response.

Background: Recently, we have identified a dysregulated protein signature in the esophageal epithelium of eosinophilic esophagitis (EoE) patients including proteins associated with inflammation and epithelial barrier function; however, the effect of proton pump inhibitor (PPI) treatment on this signature is unknown. Herein, we used a proteomic approach to investigate: (1) whether PPI treatment alters the esophageal epithelium protein profile observed in EoE patients and (2) whether the protein signature at baseline predicts PPI response.

Methods: We evaluated the protein signature of esophageal biopsies using a cohort of adult EoE (n = 25) patients and healthy controls (C) (n = 10).

Circulating immunome fingerprint in eosinophilic esophagitis is associated with clinical response to proton pump inhibitor treatment.

Objectives: The aim of the study was to characterize the circulating immunome of patients with EoE before and after proton pump inhibitor (PPI) treatment in order to identify potential non-invasive biomarkers of treatment response.

Methods: PBMCs from 19 healthy controls and 24 EoE patients were studied using a 39-plex spectral cytometry panel. The plasmacytoid dendritic cell (pDC) population was differentially characterized by spectral cytometry analysis and immunofluorescence assays in esophageal biopsies from 7 healthy controls and 13 EoE patients.

Esophageal biomechanics assessed by impedance planimetry (EndoFLIPTM) in healthy subjects and in patients with eosinophilic esophagitis. Normality values.

Background: active eosinophilic esophagitis is associated with esophageal caliber, distensibility and motility changes that may be reversed with treatment.

Objectives: to study esophageal diameter, distensibility and contractility in healthy subjects compared to patients with eosinophilic esophagitis, both before and after treatment.

Methods: a quasi-experimental study, EndoFLIP™, was used to analyze the esophageal body and esophago-gastric junction (EGJ) in all three groups, and a program was designed to obtain esophageal diameter, distensibility and contractility values.

Differences between childhood- and adulthood-onset eosinophilic esophagitis: An analysis from the EoE connect registry.

Background: Direct comparisons of childhood- and adulthood-onset eosinophilic esophagitis (EoE) are scarce.

Aim: To compare disease characteristics, endoscopic and histological features, allergic concomitances and therapeutic choices across ages.

Methods: Cross-sectional analysis of the EoE CONNECT registry.

Accurate and timely diagnosis of Eosinophilic Esophagitis improves over time in Europe. An analysis of the EoE CONNECT Registry.

Background: Poor adherence to clinical practice guidelines for eosinophilic esophagitis (EoE) has been described and the diagnostic delay of the disease continues to be unacceptable in many settings.

Objective: To analyze the impact of improved knowledge provided by the successive international clinical practice guidelines on reducing diagnostic delay and improving the diagnostic process for European patients with EoE.

Methods: Cross-sectional analysis of the EoE CONNECT registry based on clinical practice.

Practical aspects of high resolution esophageal manometry.

High resolution esophageal manometry (HRM) is currently under development as can be seen in the various Chicago classifications. In order to standardize criteria in certain practical aspects with limited scientific evidence, the First National Meeting for Consensus in High Resolution Manometry of the Spanish Digestive Motility Group took place, bringing together a wide group of experts. The proposals were based on a prior survey composed of 47 questions, an exhaustive review of the available literature and the experience of the participants.

Hypercontractile esophagus: Clinical context and motors findings in high resolution manometry.

Background: Hypercontractile esophagus (HE) is a primary hypercontractile disorder of the esophageal musculature not frequently seen in the general population. It is characterized by the presence of at least one contraction with a very high amplitude and duration (DCI > 8,000 mmHg/s/cm) in patients with esophageal symptoms. The aim of our study was to assess the clinical context and manometric characteristics in patients with HE using highresolution manometry (HRM).

Environmental risk factors in inflammatory bowel diseases. Investigating the hygiene hypothesis: a Spanish case-control study.

Objective: Environmental factors have been implicated in the etiology of inflammatory bowel disease (IBD), but evidence for the hygiene hypothesis is unclear. We investigated the relationship between early-life infection-related exposures and risk of IBD.

Patients And Methods: A hospital-based case-control study was carried out.

Cannabinoid CB1 receptors are expressed by parietal cells of the human gastric mucosa.

Experimental data suggest that the endogenous cannabinoid system is involved in gastric function in different animal species. In most of them, CB(1) receptors have been localized on vagal terminals innervating the external wall of the stomach. We aimed at studying the putative presence and distribution of these receptors in the human gastric mucosa.
