P507 Can systematic upper gastrointestinal endoscopy benefit patients with Inflammatory Bowel Disease?

Abstract Background In the context of Inflammatory Bowel Disease (IBD), a comprehensive understanding of disease extent and related complications is essential for effective clinical care. While Crohn’s disease (CD) can affect the digestive tract from mouth to anus, ulcerative colitis (UC) is limited to the rectum and colon. This study investigates the potential utility of systemic gastroscopy in IBD management. Methods We conducted a retrospective cohort study using data from our gastroenterology department. Patients diagnosed with IBD who underwent systematic upper gastro-intestinal endoscopy (UGE) were included. Clinical, endoscopic, and histopathological data were gathered and analyzed. Results 141 CD and 61 UC patients were included. The mean age was 40,7 years, and the female to male ratio was 1,33. 95.5% of these patients had no upper gastrointestinal symptoms prior to undergoing UGE. Among the symptomatic participants, the most frequent complaints were dyspepsia and pyrosis. In 73.9% of asymptomatic patients, UGE showed a normal mucosa, the abnormalities found in these patients were: non-specific gastro-duodenal erosions and ulcerations (8.5% of cases), mild esophagitis (4% of cases), aphthoid ulcerations (2% of cases) and duodenal stenosis (0.5% of cases). In symptomatic participants, UGE was normal in 4 cases, it showed atrophy of the fundus mucosa in 1 case, esophageal hernia in 2 cases, and esophageal aphthoid ulcerations in 1 case. Gastro-duodenal biopsies were consistently undertaken, among asymptomatic patients, histopathological abnormalities included: lymphoplasmacytic Infiltrate (47,7%) and helicobacter pylori (HP)(38,1 %), nonspecific duodenitis (44,7%), gastric metaplasia, focal gastritis, atrophic villi and crypt hyperplasia were objectified in 3,5%, 3%, 1,5% and 0,5% of cases. Granulomas were noted in only 1% of cases, and Cryptitis and crypt abscess in 0,5%. In symptomatic participants, histologic abnormalities included metaplasia in the fundus (0.5%), lymphoplasmacytic infiltrate (2.5%), HP (2,4%), atrophic villi in the duodenum (0.5%) and glandular atrophy (0.5%). Our analysis did not reveal any significant associations between endoscopic lesions and UC (p=0.36) or CD (p=0.09) nor the presence of symptoms (p=0.08), however, a significant association was identified between male gender and the presence of endoscopic lesions (p=0.033). Conclusion Although IBD patients might be asymptomatic, UGE and histopathological examination may reveal upper gastrointestinal abnormalities and aid to a better assessment and management of IBD patients.

Oesophageal motor disorders and oesophageal endoscopic involvement in patients with systemic sclerosis: a systematic association?

Introduction Although oesophageal motor disorders (OMDs) are frequent in systemic sclerosis (SSc), the frequency of associated endoscopic lesions is unknown. We aimed at assessing the presence of endoscopic lesions in SSc patients with OMD. The secondary objective was to identify the clinical and serological profile of such patients. Methods This retrospective study included SSc patients suffering from OMD diagnosed by oesophageal high-resolution manometry (OHRM) and with recent upper gastro-intestinal endoscopy (UGIE). Clinical data collected were age, gender, body mass index, SSc disease duration, tobacco, SSc cutaneous type, non-digestive SSc visceral disorders, oesophageal symptoms, serological profile (autoantibodies), proton pump inhibitor use, time between SSc diagnosis and UGIE. Results 53 selected patients from 210 SSc patients investigated by OHRM in our department were included. Among these patients, 25 (47.2%) had endoscopic lesions: 18 (34.6%) had oesophagitis and 7 (13.5%) had Barrett’s oesophagus. The only two parameters significantly associated with endoscopic lesions were a shorter disease duration (6 vs. 11 years; p = .002) and a shorter delay between SSc diagnosis and UGIE (3 vs. 8.5 years; p = .002). No other clinical or biological parameters could help identify the patients at risk of endoscopic lesion. Conclusion In our study, only a shorter disease duration and a shorter delay between SSc diagnosis and UGIE were significantly associated with the presence of endoscopic lesions in patients with OMD, but no other parameters were identified. This study highlights the need to perform UGIE in SSc patients with OMD whatever their clinical symptoms.

Ultrasonographic detection and assessment of the severity of Crohn's disease recurrence after ileal resection.

BackgroundRecurrence and severity of Crohn's disease mucosal lesions after "curative" ileal resection is assessed at endoscopy. Intramural lesions can be detected as increased wall thickness at Small Intestine Contrast Ultrasonography (SICUS).Aims. To assess after ileal resection whether: 1) SICUS detects recurrence of Crohn's disease lesions, 2) the intestinal wall thickness measured at the level of ileo-colonic anastomosis predicts the severity of endoscopic lesions, 3) the extension of intramural lesions of the neo-terminal ileum is useful for grading severity of the recurrence, 4) the combined measures of wall thickness of the ileo-colonic anastomosis and of the extension of intramural lesions at level of the neo-terminal ileum may predict the endoscopic Rutgeerts scoreMethodsFifty eight Crohn's disease patients (M 37, age range 19-75 yrs) were prospectively submitted at 6-12 months intervals after surgery to endoscopy and SICUS for a total of 111 observations.ResultsSix months or more after surgery wall thickness of ileo-colonic anastomosis > 3.5 mm identified 100% of patients with endoscopic lesions (p < 0.0001). ROC curve analysis, combining wall thickness of ileo-colonic anastomosis and the extension of intramural lesions of neo-terminal ileum, discriminated (0.95) patients with, from those without, endoscopic lesions. Performing two multiple logistic regression analyses only wall thickness of ileo-colonic anastomosis and extension of neo-terminal ileum intramural lesions were significantly associated with absence or presence of endoscopic lesions. An ordinal polychotomus logistic model, considering all investigated variables, confirmed that only SICUS variables were associated with endoscopic grading of severity.ConclusionsIn patients submitted to ileal resection for Crohn's disease non-invasive Small Intestine Contrast Ultrasonography 1) by assessing thickness of ileo-colonic anastomosis accurately detects initial, minimal Crohn's disease recurrence, and 2) by assessing both thickness of ileo-colonic anastomosis and extension of intramural lesions of neo-terminal ileum grades the severity of the post-surgical recurrence.

Febre transitória pós-broncofibroscopia – estudo prospectivo

The Fiberoptic bronchoscopy (BRF) is an essential tool in diagnosis and therapy of respiratory diseases. The occurrence of transient fever after BRF has been documented in some studies. Its meaning hasn't yet been clarified. Determine the incidence of fever and bacteriemia in the 24 hours after BRF and identify its predictive factors. Ninety one outpatients and forty hospitalised patients were prospectively studied in the 24h after BRF to assess the appearance of fever (T>38 masculine C) and positive hemocultures. Statistical analysis were performed using SPSS and the significance was considered when pearson chi2 was < 0,005. Referring outpatients / hospitalised patients, 68% / 85% were males, 85% / 52,5% denied previous respiratory diseases, mean age was 54 +/- 16,5 years / 59 +/- 15,4 years, 38,5% / 55% were smokers. Transient fever was observed in 12% / 12,5% patients. Positive hemocultures were found in four patients (3 outpatients and 1 hospitalised). None hospitalised patients showed radiological changes, in 7,5% cases white blood cells count rised >50%. We didn't found statistically significant association between appearance of fever after BRF and age, dental caries, smoking habits, systemic disease, presence of endoscopic lesions and endoscopic techniques performed. Transient fever following BRF is a common event and in majority of cases is not associated with bacteriemia. No statistical significant association was found between fever event and any of the studied factors.

Increased prevalence of Helicobacter pylori in patients with diabetes mellitus

Background. Whilst upper gastrointestinal disturbances are frequently observed in patients with diabetes mellitus, little is known about the prevalence of Helicobacter pylori infection and peptic disease in these patients.Aim. To evaluate prevalence of Helicobacter pylori infection and peptic disease lesions in diabetics with dyspeptic symptoms.Patients and methods. Study population comprises 74 consecutive diabetes mellitus patients with dyspepsia and 117 consecutive non diabetic dyspeptic patients. Upon enrolment, each patient completed an interview screening questionnaire to obtain information concerning presence and severity of dyspepsia. All patients underwent upper gastrointestinal endoscopy with biopsy specimens being collected from gastric antrum and body. Helicobacter pylori was evaluated in each patient by rapid urease test and histology (Giemsa). Gastritis was classified according to the Sydney System. Statistical analysis was performed by chi-square, Fisher exact or t test and logistic regression analysis. A p value <0.05 was considered significant.Results. Prevalence of Helicobacter pylori infection was found to be significantly higher in diabetics than in controls. The prevalence rate of endoscopic lesions was comparable in the two groups, but the association between endoscopic lesions and Helicobacter pylori infection was significantly higher in diabetics. Overall, the presence of chronic gastritis, both non atrophic and atrophic, as well as intestinal metaplasia were comparable in the two groups of patients, whilst the association between chronic gastritis and Helicobacter pylori infection or gastritis activity were significantly higher in diabetics. In neither group, was any correlation found between severity of dyspepsia and presence of endoscopic lesions, chronic gastritis or Helicobacter pylori infection.Conclusions. These data show a higher prevalence of Helicobacter pylori infection in diabetes mellitus patients with dyspepsia. Helicobacter pylori infection was significantly associated both with the presence of endoscopic lesions and chronic gastritis in diabetic patients, but not in the controls.

Prevalence of upper gastrointestinal lesions and Helicobacter pylori infection in Crohn's disease.

Crohn's disease can affect the upper gut with reported variable frequency, although concurrent Helicobacter pylori infection has been reported to be low. We prospectively investigated the prevalence of esophageal, gastric, and duodenal lesions and Helicobacter pylori infection in 67 Crohn's disease, 41 ulcerative colitis patients, and 43 controls. Symptoms, esophagogastroduodenoscopy, and multiple biopsies were performed on all patients consecutively. Endoscopic lesions were found in 63% of Crohn's disease patients, with a Helicobacter pylori prevalence of 28%. Granulomas were found in three patients. Twenty-two percent of the ulcerative colitis patients had lesions, with a 29% prevalence of Helicobacter pylori infection. Half of the controls had pathological endoscopy, and Helicobacter pylori was positive in 40% of the cases. Subjective symptoms did not predict the presence of endoscopic lesions or Helicobacter pylori infection in inflammatory bowel disease patients. Chronic gastritis and duodenitis are common in Crohn's disease patients, and the majority are not associated with Helicobacter pylori infection.
