Detection Rates of Non-Cavitary Epithelioid Cell Granuloma by Gastrointestinal Biopsy in Patients with Treatment-Naïve Crohn's Disease. Inflamm Intest Dis 2023; 8:105-114. [PMID: 38098493 PMCID: PMC10718578 DOI: 10.1159/000533479] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Accepted: 08/04/2023] [Indexed: 12/17/2023] Open
Abstract
Introduction Detecting non-cavitary epithelioid cell granuloma by gastrointestinal biopsy is important in the initial diagnosis of Crohn's disease (CD). In the present study, we aimed to determine the rate of granuloma detection by gastrointestinal biopsy according to the number of biopsies performed. Methods The present study included patients newly diagnosed with CD at our hospital between April 2017 and March 2023. During endoscopic examinations, biopsy specimens were taken from affected lesions. Initially, one section per biopsy was examined to detect granuloma. In cases where no granulomas were detected, step sections were additionally prepared and examined. The rate of granuloma detection by gastrointestinal biopsy was retrospectively examined. Results A total of 30 patients with a new diagnosis of CD were included in this study. In total, 284 gastrointestinal biopsies were performed in 29 cases. The rate of granuloma detection by gastrointestinal biopsy per case was 58.6% (17 out of 29 cases). The rate of granuloma detection by gastrointestinal biopsy per biopsy was 6.0% (17 out of 284 biopsies) on initial histological examination and 11.6% (33 out of 284 biopsies) following examination of step sections. The rate of granuloma detection was significantly improved by performing histological examination of step sections compared with initial examinations (p < 0.05). Conclusion The rate of granuloma detection per biopsy was 11.6%, even after histological examination of step sections. These results indicate that performing multiple intestinal biopsies and assessing for the presence of granuloma using multiple section examinations are required in the initial diagnosis of CD.

Endoscopic findings in the upper gastrointestinal tract in patients with Crohn's disease are common, highly specific, and associated with chronic gastritis. Sci Rep 2023; 13:703. [PMID: 36639398 PMCID: PMC9839771 DOI: 10.1038/s41598-022-21630-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Accepted: 09/29/2022] [Indexed: 01/14/2023] Open
Abstract
Crohn's disease (CD) may affect the entire gastrointestinal tract including its upper part. However, this aspect is poorly addressed in scientific literature and considered a rare finding. Here we aimed to prospectively investigate the prevalence, characteristics and clinical significance of upper gastrointestinal tract involvement in patients with CD, with particular focus on stomach bamboo joint-like appearance (BJA), Helicobacter pylori status and presence of microscopic changes. 375 prospectively recruited patients were included. In CD patients the prevalence of gastric and duodenal, but not esophageal, mucosal lesions, such as gastric mucosal inflammation, duodenal edema, ulcerations, and duodenal bulb deformation was significantly higher (at least p < 0.01 for all). Similar results were found when only H. pylori negative individuals were analyzed. Moreover, BJA of the stomach and in case of H. pylori negative patients also duodenal bulb deformation were detected exclusively in CD patients. Presence of BJA lesion was not significantly associated with neither duration of the disease nor use/history of biologic treatment. Despite absence of H. pylori infection microscopic features of chronic gastritis were found in almost all (93.5%) patients, and in 31% of controls (p < 0.00001). Our analysis outlines that upper gastrointestinal tract involvement in CD is a very common event and frequently manifests with a highly specific BJA lesion. Furthermore, our study reveals that in almost all CD patients features of H. pylori negative gastritis are present.

Abstract
The gastric microbiota in Crohn's disease (CD) has not been studied. The purpose of the study was to evaluate differences of stomach microbiota between CD patients and controls. DNA was extracted from gastric mucosal and fluid samples, from 24 CD patients and 19 controls. 16S rRNA gene sequencing identified 1511 operational taxonomic units (OTUs), of which 239 passed the low abundance and low variance filters. All but one CD patients were HP negative. Fifteen bacterial phyla were identified in at least one mucosal or fluid site. Of these, Bacteroidota and Firmicutes accounted for 70% of all phyla. Proteobacteria, Actinobacteriota, and Fusobacteriota combined accounted for 27%. There was significant difference in the relative abundance of Bacteroidota, Proteobacteria, Fusobacteriota, and Campilobacterota between CD patients and controls only in gastric corpus samples. In gastric liquid, there was a significant difference only in Actinobacteriota. Pairwise comparison identified 67 differentially abundant OTUs in at least one site. Of these, 13 were present in more than one comparison, and four differentiating OTUs (Neisseriaceae, Neisseria, Absconditabacteriales, and Microbacteriaceae) were identified at all tested sites. The results reveal significant changes in gastric microbial profiles (beta diversity, phylum, and individual taxa levels) between H. pylori-negative CD patients and controls.

Abstract
(1) The aim of the present study was to describe the endoscopic and histopathological findings in the esophagus, stomach, and duodenum in patients with Crohn’s disease. (2) Methods: This was a cross-sectional study that included patients receiving treatment from the inflammatory bowel disease outpatient clinic. Esophagogastroduodenoscopies with biopsies of the stomach and proximal duodenum were performed. Presence of Helicobacter pylori bacteria was assessed by Giemsa staining. (3) Results: We included 58 patients. Erosive esophagitis was identified in 25 patients (43.1%), gastritis was diagnosed in 32 patients (55.2%) and erosive duodenitis was found in eight (13.8%). The most frequent histopathological finding in the H. pylori-positive group was increased inflammatory activity in the gastric body and antrum, with a predominance of mononuclear and polymorphonuclear cells. In turn, the most frequent finding in the H. pylori-negative group was chronic inflammation with predominance of mononuclear cells. Focally enhanced gastritis was identified in four patients (6.9%), all of whom were negative for H. pylori. Granulomas were not observed. H. pylori infection was present in 19 patients (32.8%). (4) Conclusions: Nonspecific endoscopic and histological findings were frequent in patients with Crohn’s disease. Focally enhanced gastritis was uncommon and observed only in H. pylori-negative patients. The time from the diagnosis, patient age, and therapy in use may have influenced the nondetection of epithelioid granuloma.

Abstract
In daily practice, the presence of inflammation in gastric biopsies prompts a mental algorithm, an early question being whether the lesion present is Helicobacter-associated. If Helicobacter organisms are not found, then there is a further algorithm, governed by the predominant type of inflammatory cells present, and the presence of other features such as intraepithelial lymphocytosis, a subepithelial collagen band, granulomas, coexisting chronic inflammation, focality, and superimposed reactive changes including erosions and ulcers. Each of these generates its own differential diagnosis. If no inflammation is present, then the two major changes specifically looked for are the changes associated with hypergastrinaemia, by far the most common cause of which is treatment with proton pump inhibitors, and reactive changes. These may be present with and without accompanying inflammation, and, when the epithelial changes dominate, the term gastropathy is preferred. In this article, we present an approach to non-Helicobacter inflammation and gastropathies.

Associations between the Presence of Granulomata and Disease Phenotype and Outcomes in Children Diagnosed with Crohn’s Disease. GASTROINTESTINAL DISORDERS 2020.

Abstract
Background: The finding of a mucosal granuloma on histological analysis of endoscopically obtained biopsies in children with Crohn’s disease has been suggested to provide prognostic information. The aim of this study was to retrospectively assess the rate of granuloma detection and the impact of this upon specific disease characteristics and outcomes in children diagnosed with Crohn’s disease. After identification of a group of children previously diagnosed with Crohn’s disease, chart reviews were undertaken to characterise the children as granuloma positive or negative. Disease characteristics at diagnosis (such as disease location and nutritional status) and following diagnosis (such as requirement for immunosuppressive medications and surgical intervention) were noted for each patient. Results: Ninety-four children from two distinct geographical areas were identified. Forty-nine (52.1%) of the children had mucosal granulomata. Children with colonic disease were likely to have granulomata detected (RR = 3.04; p < 0.001). Granulomata were associated with lower weight z-scores at diagnosis (p < 0.05), but not other disease features (e.g., perianal disease or extra-intestinal manifestations). The presence of a granuloma at diagnosis was also associated with increased rates of the subsequent requirement for an immunosuppressive medication (RR = 1.26; p = 0.002). The presence of granulomata on histological assessment of mucosal biopsies at diagnosis of children with Crohn’s disease appears to be associated with specific disease features and outcomes. These findings should be clarified prospectively in a larger cohort of children with Crohn’s disease.

Abstract
Crohn’s disease with involvement of the esophagus, stomach and duodenum has a prevalence of 0.5% to 4% in symptomatic adult patients, but some studies have shown that these results may be underestimated, since upper gastrointestinal endoscopy is not performed routinely in the initial evaluation of the disease in adult patients, as it is in the pediatric population. In general, involvement of the upper gastrointestinal tract in Crohn’s disease occurs concomitantly with involvement of the lower gastrointestinal tract. The diagnosis depends on clinical, endoscopic, histological and radiological evaluation. The presence of aphthoid ulcers, longitudinal ulcers, bamboo-joint-like appearance, stenoses and fistulas are endoscopic findings suggestive of the disease, and it is important to exclude the presence of Helicobacter pylori infection. The primary histological findings, which facilitate the diagnosis, are the presence of a chronic inflammatory process with a predominance of lymphoplasmacytic cells and active focal gastritis. The presence of epithelioid granuloma, although less frequent, is highly suggestive of the disease in the absence of chronic granulomatous disease. Treatment should include the use of proton pump inhibitors associated with corticosteroids, immunomodulators and biological therapy according to the severity of the disease.

Abstract
PURPOSE Crohn's disease (CD) can involve any site of the gastrointestinal tract (GIT). However, the characteristics of upper GIT involvement in CD are unclear, especially in the Eastern pediatric population. This study aimed to estimate the prevalence of upper GIT involvement and identify the clinical features of Korean children with CD. METHODS This was a retrospective multicenter cohort study that included 52 pediatric patients with CD who underwent esophagogastroduodenoscopy and biopsy. The clinical symptoms and endoscopic and histologic features of the upper GIT were identified according to the presence or absence of upper gastrointestinal symptoms. RESULTS Among the 52 patients, upper GIT involvement was noted in 50.0% (26/52). The mean age at CD diagnosis was 14.1±2.1 years. Gastric ulcer was the most common lesion (19.2%) found on upper GIT endoscopy, followed by duodenal ulcers (15.4%). Chronic inflammation was the most common histopathologic feature (75.0%), followed by gastric erosion (17.3%). Granuloma was found in 9.6% of patients. Helicobacter pylori infection was identified in 5.8% of patients. Endoscopic and histologic findings were not significantly different, but the mean values of erythrocyte sedimentation rate (60.7±27.1 vs. 43.0±27.6 mm/h, p=0.037) and C-reactive protein (16.5±28.2 vs. 6.62±13.4 mg/dL, p=0.014) were significantly different between patients with and without upper gastrointestinal CD symptoms. CONCLUSION Upper GIT involvement was relatively common in pediatric patients with CD irrespective of upper gastrointestinal symptoms, and H. pylori infection was relatively uncommon. The results of this study should aid the establishment of regional guidelines for upper GIT examination.

Abstract
OBJECTIVES Granulomas have long been considered the histological hallmark of Crohn's disease (CD). Currently, there is considerable dispute with regards to their prognostic implications. We aimed to determine the effect of granulomas on phenotypic features and disease's long-term outcomes in a large cohort of pediatric CD patients. MATERIALS AND METHODS Medical records of pediatric CD patients diagnosed at the Schneider Children's Medical Center were reviewed retrospectively. Patients were categorized into two groups based on the presence or absence of granulomas at diagnosis. Baseline characteristics included anthropometric, clinical, laboratory, radiological and endoscopic data. Outcome measures included flares, hospitalizations, biological therapy and surgery. RESULTS Of 289 CD patients diagnosed between 2001 and 2015, 99 patients (34%) had granulomas. Median age of the entire cohort at diagnosis was 14.2 years (females, 42.6%), with a median follow-up of 8.5 years. Patients with granulomas had a significantly higher percentage (47.5% vs. 23.7%, p = .001) of upper gastrointestinal involvement and ileo-colonic disease (64.9% vs. 49.5%, p = .01). Extraintestinal manifestations were twice as common in patients without granulomas (16.3% vs. 8.1%, p = .05). Patients with granulomas were more likely to be hospitalized (HR =1.43, 95% CI: 1.0-2.0) and to receive biologic therapy (HR = 1.52, 95% CI: 1.1-2.11). Additionally, both of these disease outcomes occurred significantly earlier (p = .013 and p = .027, respectively). In contrast, patients with granulomas did not exhibit increased risk of flares or bowel resection. CONCLUSION Patients with granulomas exhibited a distinct phenotype at diagnosis and demonstrated a more severe disease course.

Abstract
AIM: To evaluate the role of microRNA (miR)-146a, -155 and -122 in the duodenal mucosa of pediatric patients with Crohn’s disease (CD) and the effect of transforming growth factor-β (TGF-β) on these miRs in duodenal epithelial and fibroblast cells.
METHODS: Formalin-fixed, paraffin-embedded biopsies derived from the macroscopically inflamed (CD inflamed: n = 10) and intact (CD intact: n = 10) duodenal mucosa of pediatric CD patients and control children (C: n = 10) were examined. Expression of miR-146a, -155 and -122 was determined by real-time polymerase-chain reaction (PCR). The expression of the above miRs was investigated in recombinant human TGF-β (1 nmol/L, 24 h) or vehicle treated small intestinal epithelial cells (CCL-241) and primary duodenal fibroblast cells derived from healthy children as well.
RESULTS: Expression of miR-146a was significantly higher in the inflamed duodenal mucosa compared to the intact duodenal mucosa of children with CD (CD inflamed: 3.21 ± 0.50 vs CD intact: 0.62 ± 0.26, P≤ 0.01) and to the control group (CD inflamed: 3.21 ± 0.50 vs C: 1.00 ± 0.33, P≤ 0.05). The expression of miR-155 was significantly increased in the inflamed region of the duodenum compared to the control group (CD inflamed: 4.87 ± 1.02 vs Control: 1.00 ± 0.40, P≤ 0.001). The expression of miR-122 was unchanged in the inflamed or intact mucosa of CD patients compared to controls. TGF-β treatment significantly decreased the expression of miR-155 in small intestinal epithelial cells (TGF-β: 0.7 ± 0.083 vs Control: 1 ± 0.09, P≤ 0.05) and also the expression of miR-146a (TGF-β: 0.67 ± 0.04 vs Control: 1 ± 0.15, P≤ 0.01) and miR-155 (TGF-β: 0.72 ± 0.09 vs Control: 1 ± 0.06, P≤ 0.05) in primary duodenal fibroblasts compared to corresponding vehicle treated controls. TGF-β treatment did not influence the expression of miR-122.
CONCLUSION: The elevated expression of miR-146a and -155 in the inflamed duodenal mucosa of CD patients suggests the role of these miRs in the pathomechanism of inflammatory bowel disease. Anti-inflammatory TGF-β plays an important role in the regulation of the expression of these miRs.
