Abstract
Histological assessment of endoscopic biopsies in inflammatory bowel disease [IBD] plays an important role in clinical management, investigative studies, and clinical trials. Scoring schemes consisting of multiple histological items and offering considerable precision are widely available. However, definitions of histological abnormalities are often inconsistent. Furthermore, interobserver variability for their recognition and assessment may be high. The European Crohn's and Colitis Organisation [ECCO] formed an expert panel to explore definitions of histological abnormalities in IBD, with the aim of improving the quality of diagnosis and facilitating development of scoring schemes. The process confirmed that the current definitions often have no evidence base and vary between sources. Using available evidence and expert knowledge, the panel produced a series of ECCO consensus position statements on histological features in IBD.

Flanagan A, Allsopp SM, O'Connor SA, Tobin J, Pretorius C, Brown IS, Bell S, Daveson AJM. High incidence of inflammatory bowel disease in Northern Australia: a prospective community population-based Australian incidence study in the Mackay-Isaac-Whitsunday region. Intern Med J 2023; 53:1602-1609. [PMID: 36579712 DOI: 10.1111/imj.15941] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Accepted: 09/27/2022] [Indexed: 12/30/2022]
Abstract
BACKGROUND AND AIMS To determine the incidence of inflammatory bowel disease (IBD) in the Mackay-Isaac-Whitsunday region in Northern Queensland (-21.14° S) and to allow a comparison with Southern Australian and New Zealand data (Geelong, Australia -38.14° S; Tasmania -41.43° S and -42.88° S (Launceston and Hobart) and Canterbury, New Zealand -43.46 °S). DESIGN A prospective observational community population-based IBD study was conducted between 1 June 2017 and 31 May 2018. OUTCOME MEASURES Primary includes the crude annual incidence rate of IBD, Crohn's disease (CD), ulcerative colitis (UC) and inflammatory bowel disease-unclassified (IBDU), while secondary includes disease phenotype and behaviour. RESULTS Fifty-six new cases of IBD were identified. Twenty-three were CD, 30 were UC and 3 were IBDU. The crude annual incidence rate per 100 000 for IBD, CD, UC and IBDU were 32.2 (95% confidence interval (CI): 24.78-41.84), 13.23 (95% CI: 8.79-19.90), 17.25 (95% CI: 12.06-24.67) and 1.73 (95% CI: 0.56-5.35). When directly age-standardised to the World Health Organisation Standard Population Distribution, the overall CD, UC and IBDU incidence were 13.19, 17.34 and 1.85 per 100 000, with an overall age-standardised IBD incidence of 32.38. CONCLUSIONS This is the first study to define the incidence of IBD in a Northern Australian cohort and to allow a comparison between North and Southern Australia. The IBD crude is the highest reported in Australia. Like others, we found a high and low incidence of upper gastrointestinal Crohn's disease and complicated disease at diagnosis respectively, likely reflective of the increased availability and early uptake of endoscopic procedures.

Abstract
AIMS Studies investigating the relationship between granulomatous gastritis (GG) and Helicobacter pylori infection have been largely inconclusive. This study was designed to determine whether the analysis of a very large number of patients would provide clearer answers evaluate the association between H. pylori infection and gastric granulomas. METHODS We used a large national database of clinicopathological data to extract 1,673,086 patients who underwent esophagogastroduodenoscopy with gastric biopsies between 2008 and 2020. In a case-control study, we evaluated the occurrence of H. pylori infection in patients with and without gastric granulomas. We also explored other clinical and histopathological associations. RESULTS H. pylori infection was present in 44 of 496 (8.9%) patients with gastric granulomas, compared to 158,949 (9.5%) in the control group (OR = 0.93, 95% CI = 0.68-1.26). Of the 129 patients with gastric granulomas, 50 had documented inflammatory bowel disease. CONCLUSIONS The results of this study show that the prevalence of H. pylori infection in patients with gastric granulomas is essentially identical to that of controls with no evidence of granulomas or granulomatous disease. When patients with and without a plausible-known association for gastric granulomas were analyzed separately, the prevalence of H. pylori infection remained remarkably similar in GG patients and controls. Considering the very large numbers of patients with gastric biopsies analyzed in this study, we submit that there is no basis for suggesting that H. pylori is etiologically related to GG.

Abstract
Diagnosis of the inflammatory bowel diseases ulcerative colitis (UC) and Crohn's disease (CD) relies mainly on the histopathological examination of endoscopic biopsies of the gastrointestinal tract. To facilitate the accurate diagnosis of these two conditions, this paper addresses key issues on the: (A) gastrointestinal biopsy procedure, (B) histomorphological characteristics of UC and CD, and (C) diagnosis of dysplasia. The 13 statements presented here represent the consensus of two groups of Italian pathologists (IG-IBD and GIPAD).

Esophagitis in patients without gastroesophageal reflux disease or eosinophilic esophagitis: diagnostic considerations. Curr Opin Gastroenterol 2019; 35:379-386.

Abstract
PURPOSE OF REVIEW A multitude of inflammatory diseases other than gastroesophageal reflux disease (GERD) and eosinophilic esophagitis can affect the esophagus. Despite the deceptively simple organization of squamous mucosa and its limited number of inflammatory responses, a wide array of histologic patterns can be seen in inflammatory disorders involving the esophagus. Each such histologic pattern is associated with a limited number of underlying conditions, and the clinician can use this information to narrow the differential diagnosis. The purpose of this review is to review and discuss the pathologic diagnosis of esophagitis caused by conditions other than GERD or eosinophilic esophagitis, with an emphasis on recent developments in the field. RECENT FINDINGS Recent studies suggest that lymphocytic esophagitis may be a histologic manifestation of esophageal motility disorders. Immunophenotypic features of infiltrating lymphocytes may be helpful in this scenario. immunoglobulin G4-related disease has been implicated as a cause of esophageal inflammation with ulceration, strictures, and mass-forming fibrosis, whereas epidermoid metaplasia has been linked molecularly to the squamous cell neoplasia pathway. SUMMARY Improved knowledge and appreciation of the pathology of esophageal inflammation are needed to better understand the pathogenesis of various types of esophagitis, and to inform new approaches to the therapy and management of inflammatory esophageal diseases.

Abstract
Granulomas are organised collection of activated histiocytes induced by a persistent antigen stimulus. A wide variety of antigens encountered by the gastrointestinal tract are of this nature and hence the resulting granulomatous inflammation represents a tissue reaction pattern. The potential causes can be broadly classified as infections or non-infectious immune reactions. There is also a group where a cause is never identified. Granulomas may be of varying morphological appearance, most commonly epithelioid, foreign body type, suppurative and necrotizing. This may provide a clue as to the aetiology; however, in most cases, the cause requires further inquiry. Pathologists may need to cut deeper levels to look for foreign material and apply special stains to look for microorganisms. Pathologists also need to be certain that the process is a true granuloma and not a mimic. The site of occurrence in the gastrointestinal tract and the clinical setting is often paramount in establishing the aetiology. For instance, infections are more likely the cause in developing countries or when there is immunosuppression. Similarly, granulomas in the stomach are usually due to Crohn's disease; however, it is only rarely the cause of granulomas isolated to the appendix.
