RESUMEN
BACKGROUND & AIMS: Data on factors governing long-term adherence to a gluten-free diet (GFD) in celiac disease (CD) are scarce. We aimed to determine trends and clinical predictors of long-term GFD adherence in adult CD. METHODS: Initial and long-term (>3 years) GFD adherence, clinical characteristics at baseline and follow-up were collected retrospectively from celiac patients followed-up over 20 years (2000-2020). Predictors of long-term GFD adherence at diagnosis, and follow-up were evaluated by multivariate logistic regression. RESULTS: 248 patients (37 ± 12 years, 186F, median time on a GFD 90 months) were included. Twenty-five (10.1%) had only short-term follow-up (<3 years) while 223 (89.9%) had initial and long-term dietary assessment. 187/223 (83.9%) patients were initially adherent and 36/223 (16.1%) were not. 17/36 (47.2%) patients initially not adherent become adherent, while only 4/187 (2.1%) initially adherent patients became not adherent. In the long-term, 200/223 (89.7%) were adherent and 21/223 (9.4%) patients were not. Adherence improved more frequently than worsened (OR, 39.5; 95% CI, 11.4-178.5; P < .01). Classical symptoms (diarrhea, weight loss) at diagnosis of CD predicted stricter long-term GFD adherence (OR, 3.27; 95% CI, 1.21-8.81; P = .02), while anemia (OR, 0.31; 95% CI, 0.12-0.82; P = .02) and dermatitis herpetiformis (OR, 0.23; 95% CI, 0.06-0.91; P = .04) predicted poorer long-term adherence. At follow-up, initial GFD adherence (OR, 42.70; 95% CI, 10.70-171.00; P = .04) was the major determinant of long-term GFD adherence. CONCLUSIONS: GFD adherence changes over time in <10% of patients, generally improving when it does. Major determinants of long-term GFD adherence are classical symptoms at diagnosis and initial adherence to a GFD. Patients with anemia or dermatitis herpetiformis at diagnosis require stricter dietetic input.

INTRODUCTION: The Multidimensional Prognostic Index (MPI) is a validated tool for assessing mortality risk in hospitalised patients. We aimed to evaluate whether the MPI predicted mortality and the risk of developing diverticular disease (DD) complications in older patients. METHODS: This is a multicentre study conducted in January 2016-March 2018. All patients with DD aged 65 years and older were included. Patients were stratified into three groups according to MPI groups (1, low risk; 2, moderate risk; 3, high risk). Risk of developing DD complications and mortality rate were assessed. Bivariate models were fitted. RESULTS: One hundred hospitalised patients with DD (mean age 77.9 ± 10.6 years, 53 female patients) were included. Patients with higher MPI groups were more likely to develop DD complications. In particular, 12 (46.2%), 21 (52.5%), and 28 (82.4%) patients with complicated DD were distributed to the MPI 1, MPI 2, and MPI 3 groups (p = 0.0063), respectively. Two patients died in the MPI 1, 4 in the MPI 2, and 29 in the MPI 3 group, with mortality rates of 4.0 per 100 person-year (95% confidence interval [CI] 1.0-15.9), 5.6 (95% CI 2.1-15.0), and 89.2 (95% CI 62-130), respectively (log-rank test p < 0.001). In bivariate analysis, after adjustment for age >80 years, Charlson Comorbidity Index >4, DD complications, and the presence of thromboembolism, higher MPI group was independently associated with higher mortality. Those in the MPI 3 group experienced a greater risk of 1-year hospital readmission (p < 0.001). CONCLUSION: MPI predicted mortality in patients with DD and also correlated with the risk of developing DD complications. Studies focussing on possible pathophysiological mechanisms between DD complications and MPI are needed.

BACKGROUND & AIMS: The main stages of cirrhosis (compensated and decompensated) have been sub-staged based on clinical, endoscopic, and portal pressure (determined by the hepatic venous pressure gradient [HVPG]) features. Vasodilation leading to a hyperdynamic circulatory state is central in the development of a late decompensated stage, with inflammation currently considered a key driver. We aimed to assess hepatic/systemic hemodynamics and inflammation (by C-reactive protein [CRP]) among the different sub-stages of cirrhosis and to investigate their interrelationship and prognostic relevance. METHODS: A single center, prospective cohort of patients with cirrhosis undergoing per protocol hepatic and right-heart catheterization and CRP measurement, were classified into recently defined prognostic stages (PS) of compensated (PS1: HVPG ≥6â¯mmHg but <10â¯mmHg; PS2: HVPG ≥10â¯mmHg without gastroesophageal varices; PS3: patients with gastroesophageal varices) and decompensated (PS4: diuretic-responsive ascites; PS5: refractory ascites) disease. Cardiodynamic states based on cardiac index (L/min/m2) were created: relatively hypodynamic (<3.2), normodynamic (3.2-4.2) and hyperdynamic (>4.2). RESULTS: Of 238 patients, 151 were compensated (PS1â¯=â¯25; PS2â¯=â¯36; PS3â¯=â¯90) and 87 were decompensated (PS4â¯=â¯48; PS5â¯=â¯39). Mean arterial pressure decreased progressively from PS1 to PS5, cardiac index increased progressively from PS1-to-PS4 but decreased in PS5. HVPG, model for end-stage liver disease (MELD), and CRP increased progressively from PS1-to-PS5. Among compensated patients, age, HVPG, relatively hypodynamic/hyperdynamic state and CRP were predictive of decompensation. Among patients with ascites, MELD, relatively hypodynamic/hyperdynamic state, post-capillary pulmonary hypertension, and CRP were independent predictors of death/liver transplant. CONCLUSIONS: Our study demonstrates that, in addition to known parameters, cardiopulmonary hemodynamics and CRP are predictive of relevant outcomes, both in patients with compensated and decompensated cirrhosis. LAY SUMMARY: There are two main stages in cirrhosis, compensated and decompensated, each with a main relevant outcome. In compensated cirrhosis the main relevant outcome is the development of ascites, while in decompensated cirrhosis it is death. Major roles of cardiac dysfunction and systemic inflammation have been hypothesized in the evolution of the disease in decompensated patients. In this study, we have shown that these factors were also involved in the progression from compensated to decompensated stage.

OBJECTIVE: Bile acid diarrhea is a form of chronic diarrhea caused by excessive bile reaching the colon. Conditions involving the terminal ileum and cholecystectomy are predisposing factors but an idiopathic form of bile acid diarrhea has also been described. In this study we aimed to evaluate the prevalence of bile acid diarrhea in patients consecutively evaluated for chronic diarrhea in an Outpatient Gastroenterology Clinic. METHODS: Medical records of all patients admitted for chronic diarrhea (>4 weeks) between June 2018 and April 2019 were retrospectively reviewed. Bile acid diarrhea was suspected in patients with ileal disease, cholecystectomy or post-prandial diarrhea. Patients' age at diagnosis, sex, presenting symptoms, results of main test and examinations, final diagnoses and date of last follow-up visit were also collected. Exclusion of chronic diarrhea of other causes and a 6-month clinical improvement with cholestyramine treatment confirmed the diagnosis of bile acid diarrhea. RESULTS: In total, 139 patients aged 46 ± 20 years (76 women and 63 men) were included. Diarrhea due to an organic cause was diagnosed in 16 patients. A clinical response to cholestyramine persisting for more than 6 months led to a diagnosis of bile acid diarrhea in 39 (aged 52 ± 19 years) out of the remaining 123 patients with functional forms of diarrhea. Therefore, the prevalence of bile acid diarrhea was 28.1% (95% confidence interval 19.9%-38.4%) in patients with chronic diarrhea. CONCLUSIONS: Bile acid diarrhea is a very common, yet under-recognized cause of chronic functional diarrhea. A therapeutic trial of cholestyramine is a valid diagnostic strategy.

BACKGROUND: Clinical elements differentiating enteropathy due to angiotensin II-receptor-blockers (ARBs-E) from coeliac disease (CD) are poorly defined. The histopathological features on duodenal and gastric biopsies in these patients still need to be investigated. AIMS: To describe the clinical phenotype of ARBs-E in comparison to CD, and the histological findings of gastric and duodenal biopsies in ARBs-E. METHODS: Clinical data of patients with ARBs-E and CD diagnosed between 2013 and 2020 were retrospectively reviewed. Baseline presenting symptoms and demographics were compared (Fisher's exact test and t-test). Gastric and duodenal histology in ARBs-E were revised by two independent pathologists. RESULTS: 14 ARBs-E and 112 CD patients were enroled. Weight loss (p < 0.01), acute onset of diarrhoea (p < 0.01), hospitalization (p < 0.01), and older age at diagnosis (p < 0.01) were more common in ARBs-E. Duodenal histology in ARBs-E showed intraepithelial lymphocytosis in 71%, increased mucosal eosinophilic count in 57%, with preserved neuroendocrine, Paneth and goblet cells in all patients. Gastric histologic lesions at baseline, including lymphocytic gastritis, eosinophilic gastritis, chronic active gastritis, and metaplastic atrophic gastritis patterns were observed in 73% of patients, without Helicobacter pylori infection. CONCLUSIONS: ARBs-E showed a severe clinical phenotype, often requiring hospital admission. Gastric involvement at diagnosis is very common, and this could further support this diagnosis.

BACKGROUND: Colorectal cancer (CRC) diagnosed before the age of 50, known as early-onset CRC (eoCRC), is considered uncommon. We aimed at analysing the incidence of preneoplastic and neoplastic lesions of the colon and rectum in patients under 50 years old and to identify possible predictors Methods: We retrospectively collected data from 1778 patients under 50 years old (mean age 39.9±7.8) referred for colonoscopy between 2015-2018. Cumulative incidence of adenomas and eoCRC was assessed. Multivariable regression models were fitted Results: The cumulative incidence for adenomas was 11.0% (95% CI 9-12), while it was 1.5% (95% CI 1-2) for eoCRC (metastatic disease in 13/27 patients). Age as a continuous variable was associated with the presence of adenomas (incidence rate ratio 1.06; 95% CI 1.03-1.09; p<0.001). EoCRC arose in most cases in the rectum (13/27, 48.1%). Age ≥40 was the main risk factor (OR 2.25; 95% CI 1.35-3.73; p=0.002) for both adenomas (160/196 patients, 81.6%) and eoCRC (20/27 patients, 74.1%), while smoking seemed to have no role (p=0.772). The presence of alarm symptoms was statistically significant at bivariable analysis for eoCRC only (OR 3.70; 95% CI 1.49-9.22; p=0.005), as well as having multiple gastrointestinal symptoms (OR 19.85; 95% CI 2.64-149.42; p=0.004). Only 3/27 (11.1%) patients with eoCRC had a family history for CRC Conclusions: A high cumulative incidence rate of both adenomas and eoCRC was found, this latter occurring more common in patients aged 40-49, without apparent risk factors. The presence of alarm symptoms or multiple gastrointestinal symptoms led to a late diagnosis.

Gluten-sensitive enteropathy of the Irish Setter is an immune-mediated intolerance to gluten, the protein found in wheat, barley, rye, and oats, reminiscent of human celiac disease. Intestinal histological lesions include partial villous atrophy, infiltration of the lamina propria by lymphocytes and plasma cells, and an increased intraepithelial lymphocyte count. Gluten-sensitive enteropathy is transmitted via autosomal recessive inheritance and its pathogenesis appears to involve cell-mediated immunity but not humoral immunity. In comparison to healthy dogs, levels of antigliadin antibodies in diseased Irish Setters are lower, although the significance of this finding is unclear. Irish Setters affected by gluten-sensitive enteropathy present with chronic intermittent diarrhea and weight loss. The use of a gluten-free diet is indispensable both for diagnosis of the disease and for therapy. In this review we discuss the similarities between gluten-sensitive enteropathy of the Irish Setter and human celiac disease.

Background: Endoscopy plays a fundamental role in the management of patients with inflammatory bowel disease (IBD). The aim of this study was to prospectively evaluate the tolerability and efficacy of bowel preparation and colonoscopy in ulcerative colitis (UC) and Crohn's disease (CD) patients compared to subjects participating in a colorectal cancer population screening program. Methods: Consecutive enrolment of CD and UC patients and screening subjects (SS) undergoing colonoscopy. Bowel preparation was done by split dose of 2 L PEG-ELS + simethicone. We recorded endoscopic, clinical, and demographic features; cleanliness rating using the Boston Bowel Preparation Scale (BBPS); and sedation doses. Bowel-preparation tolerability, discomfort, and pain during colonoscopy were assessed using a Visual Analogue Scale from 0 to 100 mm. Results: Sixty-three UC (mean age 49.9 ± 14.9 years), 63 CD (mean age 44.0 ± 14.0 years), and 63 SS (mean age 59.9 ± 6.3 years) patients were enrolled. Bowel preparation was similarly tolerated in UC, CD, and SS (P = 0.397). A complete colonoscopy was similarly performed in UC (59/63, 93.7%), CD (58/63, 92.1%), and SS (60/63, 95.2%) (P = 0.364). The BBPS did not show significant differences between UC (6.2 ± 1.6), CD (6.1 ± 1.3), and SS (6.2 ± 1.4) (P = 0.824). The need to increase sedation doses was significantly higher in CD (24/63, 38.1%) and UC (16/63, 25.4%) than in SS (4/63, 6.3%) (P < 0.0001). Conclusions: Bowel preparation is equally tolerated and efficacious in IBD patients and in healthy SS. In IBD, higher sedation doses are needed to guarantee an equally tolerated colonoscopy.
RESUMEN
OBJECTIVES: Exclusion of organic disorders involving the upper gastrointestinal (UGI) is a mandatory step before considering a biopsy-avoidance diagnostic strategy for adult coeliac disease. We aim to evaluate the prevalence of alarm symptoms and coincidental UGI endoscopic findings at the time of diagnosis of coeliac disease. To develop consensus criteria to identify patients with coeliac disease requiring a gastroscopy and to evaluate whether alarm symptoms prompting gastroscopy were predictive of endoscopic findings. METHODS: Presenting symptoms and UGI endoscopic findings at diagnosis of coeliac disease were collected retrospectively in 278 adult patients with coeliac disease diagnosed in Pavia between January 1999 and December 2017. A panel of experts developed criteria to evaluate which clinical scenarios warrant gastroscopy, which was then applied retrospectively to patients diagnosed in Pavia. RESULTS: At least one alarm symptom was present in 177/278 patients, 121/278 met our criteria for gastroscopy. Major UGI endoscopic findings included 3 cases of autoimmune atrophic gastritis, 19 oesophagitis and 20 Helicobacter pylori infections. No organic disorders were found. Prevalence of major endoscopic findings did not differ between patients who met our criteria and those who did not. CONCLUSIONS: Despite the high prevalence of alarm symptoms at diagnosis, coincident major UGI endoscopic findings are rare in adult coeliac disease. These results may be relevant for future developments in coeliac disease diagnosis in adults.
