Attending Training Courses on Barrett's Esophagus Improves Adherence to Guidelines: A Survey from the Italian Society of Digestive Endoscopy.

BACKGROUND: Little is known on practice patterns of endoscopists for the management of Barrett's esophagus (BE) over the last decade. AIMS: Our aim was to assess practice patterns of endoscopists for the diagnosis, surveillance and treatment of BE. METHODS: All members of the Italian Society of Digestive Endoscopy (SIED) were invited to participate to a questionnaire-based survey. The questionnaire included questions on demographic and professional characteristics, and on diagnosis and management strategies for BE. RESULTS: Of the 883 SIED members, 259 (31.1%) completed the questionnaire. Of these, 73% were males, 42.9% had > 50 years of age and 68.7% practiced in community hospitals. The majority (82.9%) of participants stated to use the Prague classification; however 34.5% did not use the top of gastric folds to identify the gastro-esophageal junction (GEJ); only 51.4% used advanced endoscopy imaging routinely. Almost all respondents practiced endoscopic surveillance for non-dysplastic BE, but 43.7% performed eradication in selected cases and 30% practiced surveillance every 1-2 years. The majority of endoscopists managed low-grade dysplasia with surveillance (79.1%) and high-grade dysplasia with ablation (77.1%). Attending a training course on BE in the previous 5 years was significantly associated with the use of the Prague classification (OR 4.8, 95% CI 1.9-12.1), the top of gastric folds as landmark for the GEJ (OR 2.45, 95% CI 1.27-4.74) and advanced imaging endoscopic techniques (OR 3.33, 95% CI 1.53-7.29). CONCLUSIONS: Practice patterns for management of BE among endoscopists are variable. Attending training courses on BE improves adherence to guidelines.

Acupuncture and Related Therapies for the Treatment of Gastrointestinal Diseases.

Gastrointestinal diseases are very common worldwide. Patients with gastroesophageal reflux disease, functional dyspepsia, irritable bowel syndrome, and inflammatory bowel diseases frequently recur to complementary medicine, including acupuncture, likely because of the recurrence of symptoms and the sometimes lack of efficacy of conventional treatments. Acupuncture is a medical practice used in Asian country with benefits for thousands years. In the last decades, growing attention has been given to acupuncture also in Western countries and many studies have investigated the role of acupuncture in gastroenterology. This review provided an overview of the effectiveness and potential mechanisms of action of acupuncture for the treatment of gastrointestinal diseases.

Treatment of Helicobacter pylori infection: A clinical practice update.

BACKGROUND: Helicobacter pylori infection is still frequent in the community and all infected subjects should be offered an eradication therapy. Nowadays physicians have to face the challenge of antibiotic resistance in treating Helicobacter pylori-infected individuals. AIM: This review provides an overview of current international guidelines and reports recent evidence from systematic reviews and clinical trials on the treatment of Helicobacter pylori infection and should help physicians to better treat their patients. RESULTS: General rules to optimize the management of Helicobacter pylori infection include: (i) considering previous patient's exposure to antibiotics; (ii) using high dose of proton-pump inhibitors; and (iii) avoiding repeating the same regimen, if it has already failure. Bismuth quadruple therapy and concomitant therapy are the best first-line empirical treatments in areas with high clarithromycin resistance and in individuals with previous use of macrolides; otherwise, the 14-day clarithromycin-containing triple therapy is a valid regimen. The sequential therapy is no longer a suggested treatment by international guidelines. CONCLUSIONS: Current international guidelines are consistent in defining treatment strategies for Helicobacter pylori infection. The use of national registries to monitor the efficacy and tolerability of different regimens in the real world of clinical practice is now needed.

Pattern of food intolerance in patients with gastro-esophageal reflux symptoms.

BACKGROUND: Many food items have been involved in gastro-esophageal reflux disease pathogenesis and dietary modification has been proposed as first-line treatment. Test-based exclusion diets have shown to significantly reduce reflux symptoms. We aimed to assess the patterns of food intolerance in a series of patients with typical gastro-esophageal reflux symptoms (GERS). METHODS: We retrospectively evaluated all patients with typical reflux symptoms, attending the Centre Study Association on Food Intolerance and Nutrition of Ferrara from January 2010 to October 2015, who resulted positive to at least one food item at the Leucocytotoxic Test. The presence and severity of typical GERS (heartburn and/or acid regurgitation) were assessed using the Gastro-esophageal Reflux Disease Impact Scale (GIS) questionnaire. Only individuals with a GIS Score of at least 5 points were included. RESULTS: Almost all patients (91.1%) were intolerant to at least 5 food items. The most frequent food intolerance (more than 33% of patients) were found for milk (55.4%), lettuce (46.4%), coffee (43.7%), brewer's yeast (42.9%), pork (42.9%), tuna (37.5%), rice (35.7%), sole (34.8%), asparagus (34.8%) and eggs (33.9%). Nine different clusters of food intolerance were detected. CONCLUSIONS: Patients with typical gastro-esophageal reflux symptoms seem to have intolerance to multiple food items, some of which (lettuce, brewer's yeast, tuna, rice, sole and asparagus) have not yet been associated to gastro-esophageal reflux disease.

Proton pump inhibitors: Risks of long-term use.

Proton pump inhibitors are among the most commonly prescribed classes of drugs, and their use is increasing, in particular for long-term treatment, often being over-prescribed and used for inappropriate conditions. In recent years, considerable attention has been directed towards a wide range of adverse effects, and even when a potential underlying biological mechanism is plausible, the clinical evidence of the adverse effect is often weak. Several long-term side effects have been investigated ranging from interaction with other drugs, increased risk of infection, reduced intestinal absorption of vitamins and minerals, and more recently kidney damage and dementia. The most recent literature regarding these adverse effects and their association with long-term proton pump inhibitor treatment is reviewed, and the mechanisms through which these possible complications might develop are discussed.

Prevalence of upper gastrointestinal endoscopic findings in the community: A systematic review of studies in unselected samples of subjects.

BACKGROUND AND AIM: Upper gastrointestinal endoscopic findings, such as esophagitis, Barrett's esophagus, peptic ulcer, and malignancy, represent a public health problem. This systematic review aimed to evaluate the prevalence of upper gastrointestinal endoscopic findings in the community. METHODS: A systematic search was conducted in PUBMED and EMBASE to May 2015. Studies were eligible if they reported the prevalence of upper gastrointestinal endoscopic findings in unselected samples of the community. RESULTS: Twelve articles were eligible, nine reported data from three endoscopic surveys (n = 3063 subjects), and three from national screening programs (n = 84 153). The overall prevalence of upper gastrointestinal endoscopic findings in the community was 30% in the Kalixanda study (Sweden), 24.9% in the Loiano-Monghidoro study (Italy), and 68.9% in the Systematic Investigation of Gastrointestinal Diseases study (China). The pooled prevalence of esophagitis, endoscopically suspected esophageal metaplasia (ESEM), peptic ulcer, and gastric cancer in all studies was 11.2, 5.1, 6.8, and 0.33%, respectively. The most frequent finding was esophagitis in Europe, with a prevalence of 15.5% in Sweden and 11.8% in Italy, and peptic ulcer in China (17.1%), both in asymptomatic and symptomatic individuals. The prevalence of Helicobacter pylori was positively associated with the prevalence of peptic ulcer (r = 0.91) but negatively associated with the prevalence of both esophagitis (r = -0.99) and ESEM (r = -0.95). CONCLUSIONS: Upper gastrointestinal endoscopic findings are present in at least a quarter of subjects in the community with different patterns in Western and Eastern countries, both in asymptomatic and symptomatic subjects. H. pylori prevalence negatively impacts on the prevalence of reflux-related esophageal findings.
