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.
ObjectiveBile 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.MethodsMedical 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.ResultsIn 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.ConclusionsBile 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
Endoscopy plays a fundamental role in the management of patients with inflammatory bowel disease (IBD). Aims: 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); sedation doses. Bowel-preparation tolerability, discomfort and pain during colonoscopy were assessed using a Visual Analogue Scale (VAS) from 0 to 100 mm.
Results
63 UC (mean age 49.9 ± 14.9 yrs), 63 CD (mean age 44.0 ± 14.0 yrs) and 63 SS (mean age 59.9 ± 6.3) 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 screening subjects. In IBD, higher sedation doses are needed to guarantee an equally tolerated colonoscopy.
