Combination of Bismuth and Standard Triple Therapy Eradicates Helicobacter pylori Infection in More than 90% of Patients.

BACKGROUND & AIMS: Due to the poor eradication rates of standard triple therapy, the addition of bismuth salts has been proposed for first-line eradication of Helicobacter pylori. We assessed the effectiveness and safety of the combination of bismuth and the standard, clarithromycin-containing triple therapy in eradication of H pylori infection, using data from a large multi-center registry. METHODS: We performed an interim analysis of data from the European Registry on H pylori Management, a prospective trial registering clinical data and outcomes from infected patients from 27 countries in Europe since 2013. We extracted data on 1141 treatment-naïve patients who received first-line treatment with bismuth salts (240 mg) and a proton pump inhibitor (57% received esomeprazole, 18% received omeprazole, 11% received pantoprazole, and 14% received rabeprazole), amoxicillin (1 g), and clarithromycin (500 mg), all taken twice daily. RESULTS: Intention to treat and per-protocol rates of eradication were 88% and 94%, respectively. Intention to treat eradication increased to 93% in patients who received 14-day treatments. Adverse events occurred in 36% of patients; 76% of these events were mild, with a mean duration of 6 days. In multivariate analysis, eradication was associated with treatment compliance (odds ratio [OR], 13.0), a double dose (equivalent to 40 mg omeprazole) of proton pump inhibitor (OR, 4.7), and 14-day duration of treatment (OR, 2.0). CONCLUSIONS: In an analysis of data from a large multi-center registry, we found the addition of bismuth to 14-day standard triple therapy with clarithromycin and amoxicillin to eradicate H pylori infection in more than 90% of patients, based on intention to treat analysis, with an acceptable safety profile and level of adherence.

Rising incidence and prevalence of adult eosinophilic esophagitis in midwestern Spain (2007-2016).

OBJECTIVES: Epidemiologic studies on eosinophilic esophagitis (EoE) are scarce and patient responders to proton pump inhibitor (PPI) therapy have usually been excluded. We aimed to evaluate population-based incidence rates, prevalence and trends in adult EoE over the past decade, including responders to PPI therapy. METHODS: We conducted an analysis of a prospectively established case registry in the health area of Cáceres, located in midwestern Spain. From the first EoE case diagnosed in 2007, endoscopy and pathology reports up to December 2016 were manually reviewed. A baseline diagnosis of EoE was confirmed upon symptoms of esophageal dysfunction (dysphagia/food impaction) and esophageal eosinophilia ≥ 15 eos/HPF. All patients were re-evaluated on PPI therapy during follow-up. RESULTS: A total of 137 patients were diagnosed with EoE during the study period, of whom 63 (46%) achieved clinicohistologic remission on PPI therapy. The prevalence of autoimmune disorders was low. Mean incidence rate was 8.09 new cases/100,000 inhabitants/year, increasing to 9.95 during the last lustrum and peaking in 2016 with 13.7. This trend coincided with late declining of esophageal biopsies rate. Overall prevalence in 2016 was 81.73 patients/100,000 inhabitants, with the highest prevalence in males between age 35 and 44 years (273 cases/100,000). No seasonal variation was observed in the diagnosis of EoE (53% during pollen season vs. 47%, p = 0.4). CONCLUSIONS: In midwestern Spain, incidence (13.7 cases/100,000 inhabitants/year) and prevalence (81.73 patients/100,000 inhabitants) in 2016 have grown remarkably in just one decade, coming closer to those figures recently reported for Crohn's disease in Spain.

Update on dietary therapy for eosinophilic esophagitis in children and adults.

INTRODUCTION: Eosinophilic esophagitis (EoE) is a chronic inflammatory esophageal disease triggered predominantly, but not excusively, by food antigens. Elimination diet thus remains the only therapy targeting the cause of the disease. Importantly, EoE is a unique form of non-IgE mediated food allergy, largely dependant upon delayed, cell-mediated hypersensitivity. Areas covered: A comprehensive review of literature to summarize and update the most relevant advances on dietary therapy for pediatric and adult EoE patients is conducted. Expert commentary: None of the currently available food allergy tests adequately predict food triggers for EoE, especially in adults. Elemental diet (exclusive feeding with aminoacid-based formulas) and empiric six-food elimination diet, withdrawing cow´s milk, wheat, egg, soy, nuts and fish/seafood for 6 weeks, have consistently shown the best cure rates. However, their high level of restriction and need for multiple endoscopies (top-down approach) have been a deterrent for patients and physicians. Less restrictive empiric schemes, like a four-food (animal milk, gluten-containing cereals, egg, legumes) or a two-food (animal milk and gluten-containing cereals) elimination diet have lately shown encouraging results. Therefore, a novel step-up strategy (2-4-6) may enhance patient uptake and promptly identify most responders to empiric diets with few food triggers, besides saving unnecessary dietary restrictions and endoscopic procedures.

The role of proton pump inhibitor therapy in the management of eosinophilic esophagitis.

Eosinophilic esophagitis (EoE) is a chronic esophageal disease characterized by a Th2 inflammatory response triggered by food/environmental allergens. Solid data confirm that up to half of patients with suspected EoE achieve complete remission on proton pump inhibitors (PPI) therapy. This disease phenotype is currently labelled as PPI-responsive esophageal eosinophilia (PPI-REE). Albeit initially believed to represent gastro-esophageal reflux disease (GERD), evolving evidence has underscored that PPI-REE and EoE show a significant overlap regarding clinic, endoscopic, histologic, Th2 immune-mediated inflammation and gene expression features. Moreover, PPI therapy can effectively reverse Th2 inflammation and the EoE transcriptome expression in PPI-REE patients. Therefore, EoE and PPI-REE likely represent a common allergic disorder, where PPI therapy should be considered a short- and long-term therapeutic asset, along with diet and topical steroids.
