Background/Aim:Prevalence of gastroduodenal endoscopic and histological lesions may modify over time due to different factors. We assessed both macroscopic and histological lesions currently detected at upper endoscopy performed in routine practice. Patients and Methods:Clinical, endoscopic, and histological data of consecutive adult patients referred for upper endoscopy in the 28 participating centres were analysed. Only patients who underwent the first endoscopic examination were considered. Prevalence of erosive/ulcerative lesions, cancers and extensive precancerous lesions in the stomach, and Helicobacter pyloriinfection was computed. Results:A total of 1,431 patients underwent endoscopy for gastro-oesophageal reflux symptoms (31.5%), dyspepsia (29.4%), or alarm symptoms (18.5%). Erosive oesophagitis or Barrett’s oesophagus was detected in 210 (14.7%) cases, peptic ulcer in 49 (3.4%), and a neoplastic lesion in 17 (1.2%). H. pyloriwas present in 201 (22.6%) cases, and extensive precancerous lesions on gastric mucosa in 46 (5.6%) patients. Gastric lesions were more prevalent in patients aged ≥50 years (26% vs. 18%; p= 0.001), and peptic ulcers were more frequently detected in patients with H. pylori(9.4% vs. 2.3%; p= 0.001) and in males (5.8% vs. 1.6%; p= 0.001), while neoplastic lesions in patients with alarm symptoms (3.8% vs. 0.6%; p= 0.001). Conclusions:The overall endoscopic lesions were more prevalent in patients aged ≥50 years, peptic ulcer and erosions were more frequent in H. pylori-infected patients, and extensive gastric precancerous lesions were present in less than 6% of cases.

The Diverticular Inflammation and Complication Assessment (DICA) classification and the Combined Overview on Diverticular Assessment (CODA) were found to be effective in predicting the outcomes of Diverticular Disease (DD). We ascertain whether fecal calprotectin (FC) can further aid in improving risk stratification. A three‐year international, multicentre, prospective cohort study was conducted involving 43 Gastroenterology and Endoscopy centres. Survival methods for censored observations were used to estimate the risk of acute diverticulitis (AD) in newly diagnosed DD patients according to basal FC, DICA, and CODA. The net benefit of management strategies based on DICA, CODA and FC in addition to CODA was assessed with decision curve analysis, which incorporates the harms and benefits of using a prognostic model for clinical decisions. At the first diagnosis of diverticulosis/DD, 871 participants underwent FC measurement. FC was associated with the risk of AD at 3 years (HR per each base 10 logarithm increase: 3.29; 95% confidence interval, 2.13–5.10) and showed moderate discrimination (c‐statistic: 0.685; 0.614–0.756). DICA and CODA were more accurate predictors of AD than FC. However, FC showed high discrimination capacity to predict AD at 3 months, which was not maintained at longer follow‐up times. The decision curve analysis comparing the combination of FC and CODA with CODA alone did not clearly indicate a larger net benefit of one strategy over the other. FC measurement could be used as a complementary tool to assess the immediate risk of AD. In all other cases, treatment strategies based on the CODA score alone should be recommended.

ObjectiveTo investigate the predictive value of the Diverticular Inflammation and Complication Assessment (DICA) classification and to develop and validate a combined endoscopic-clinical score predicting clinical outcomes of diverticulosis, named Combined Overview on Diverticular Assessment (CODA).DesignA multicentre, prospective, international cohort study.Setting43 gastroenterology and endoscopy centres located in Europe and South America.Participants2215 patients (2198 completing the study) at the first diagnosis of diverticulosis/diverticular disease were enrolled. Patients were scored according to DICA classifications.InterventionsA 3-year follow-up was performed.Main outcome measuresTo predict the acute diverticulitis and the surgery according to DICA classification. Survival methods for censored observation were used to develop and validate a novel combined endoscopic-clinical score for predicting diverticulitis and surgery (CODA score).ResultsThe 3-year cumulative probability of diverticulitis and surgery was of 3.3% (95% CI 2.5% to 4.5%) in DICA 1, 11.6% (95% CI 9.2% to 14.5%) in DICA 2 and 22.0% (95% CI 17.2% to 28.0%) in DICA 3 (p<0.001), and 0.15% (95% CI 0.04% to 0.59%) in DICA 1, 3.0% (95% CI 1.9% to 4.7%) in DICA 2 and 11.0% (95% CI 7.5% to 16.0%) in DICA 3 (p<0.001), respectively. The 3-year cumulative probability of diverticulitis and surgery was ≤4%, and ≤0.7% in CODA A; <10% and <2.5% in CODA B; >10% and >2.5% in CODA C, respectively. The CODA score showed optimal discrimination capacity in predicting the risk of surgery in the development (c-statistic: 0.829; 95% CI 0.811 to 0.846) and validation cohort (c-statistic: 0.943; 95% CI 0.905 to 0.981).ConclusionsDICA classification has a significant role in predicting the risk of diverticulitis and surgery in patients with diverticulosis, which is significantly enhanced by the CODA score.Trial registration numberNCT02758860.

Background:There are no evidence-based recommendations for performing upper gastrointestinal endoscopy (UGIE) in patients with extra-oesophageal symptoms of gastro-oesophageal reflux disease (GORD). However, UGIEs are often performed in clinical practice in these patients. We aimed to assess the prevalence of gastro-oesophageal lesions in patients with atypical GORD symptoms. Methods:Patients complaining of at least one extra-oesophageal GORD symptom and undergoing UGIE in seven centres were prospectively enrolled. Clinically relevant lesions (Barrett’s oesophagus, erosive oesophagitis, gastric precancerous conditions, peptic ulcer, cancer, and H. pyloriinfection) were statistically compared between groups regarding GORD symptoms (atypical vs. both typical and atypical), type of atypical symptoms, age, and presence of hiatal hernia. Results:Two hundred eleven patients were enrolled (male/female: 74/137; mean age: 55.5 ± 14.7 years). Barrett’s oesophagus was detected in 4 (1.9%), erosive oesophagitis in 12 (5.7%), gastric precancerous conditions in 22 (10.4%), and H. pyloriinfection in 38 (18%) patients. Prevalence of clinically relevant lesions was lower in patients with only atypical GORD symptoms (28.6 vs. 42.5%; p= 0.046; χ2 test), in patients ≤50 years (20 vs. 44.8%; p= 0.004; χ2 test), and in those in ongoing proton pump inhibitor (PPI) therapy (21.1 vs. 40.2%; p= 0.01; χ2 test). No clinically relevant lesions were detected in patients ≤50 years, without alarm symptoms, and receiving PPI therapy. Hiatal hernia was diagnosed in only 6 patients with cardiologic and in 41 patients with ear-nose-throat symptoms (11.3 vs. 35.1%; p= 0.03; χ2 test). Conclusions:Clinically relevant lesions are uncommon among young (≤50 years) patients with extra-oesophageal GORD symptoms. Hiatal hernia is not more prevalent in patients with cardiologic symptoms and suspicion of GORD. The usefulness of UGIE in these patients is questionable.

Background Although diverticular disease is a common condition, its effective treatment is challenging in clinical practice.Objective The objective of this article is to assess pharmacological management in different clinical settings of diverticular disease and factors associated with treatment using the Italian registry Registro Malattia Diverticolare (REMAD).Methods At study enrolment, patients were categorised into subgroups: diverticulosis, symptomatic uncomplicated diverticular disease and previous diverticulitis. We registered demographic, clinical and lifestyle factors, quality of life and the use of treatments for diverticular disease in the last year. Logistic regression analysis assessed the association between clinical factors and treatment consumption.Results A total of 500 of the 1206 individuals included had had at least one treatment for diverticular disease in the last year: 23.6% (166/702) of patients with diverticulosis, 55.9% (165/295) of patients with symptomatic diverticular disease, and 80.9% (169/209) of patients with previous diverticulitis (p< 0.001). In multivariate analysis, the following factors were significantly associated with treatment use: female gender, family history of colonic diverticula, organic digestive comorbidity and impaired physical quality of life components.Conclusion Individuals with diverticular disease take medications based on the different clinical settings of disease. We identified different features associated with treatment use in the distinct clinical entities of diverticular disease. ClinicalTrial.gov Identifier:NCT03325829.

The goals of this study were to investigate the role of a new probiotic preparation (Lactobacillus reuteriDSM 17938 and L. reuteriATCC PTA 6475) in Helicobacter pyloriinfection.

BACKGROUND: Helicobacter pylori eradication rates achieved by standard seven-day triple therapies are decreasing in several countries, while a novel 10-day sequential regimen has achieved a very high success rate. A longer 10-day triple therapy, similar to the sequential regimen, was tested to see whether it could achieve a better infection cure rate.METHODS: Patients with nonulcer dyspepsia and H pylori infection were randomly assigned to one of the following three therapies: esomeprazole 20 mg, clarithromycin 500 mg and amoxycillin 1 g for seven days or 10 days, or a 10-day sequential regimen including esomeprazole 20 mg plus amoxycillin 1 g for five days and esomeprazole 20 mg, clarithromycin 500 mg and tinidazole 500 mg for the remaining five days. All drugs were given twice daily. H pylori eradication was checked four to six weeks after treatment by using a 13C-urea breath test.RESULTS: Overall, 213 patients were enrolled. H pylori eradication was achieved in 75.7% and 77.9%, in 81.7% and 84.1%, and in 94.4% and 97.1% of patients following seven-day or 10-day triple therapy and the 10-day sequential regimen, at intention-to-treat and per protocol analyses, respectively. The eradication rate following the sequential regimen was higher than either seven-day (P=0.002) or 10-day triple therapy (P=0.02), while no significant difference emerged between the latter two regimens (P=0.6).CONCLUSIONS: The 10-day sequential regimen was significantly more effective than both triple regimens, while 10-day triple therapy failed to significantly increase the H pylori eradication rate achieved by the standard seven-day regimen.
