Abstract
A 60-year-old man with type 2 diabetes mellitus treated with a dipeptidyl peptidase-4 (DPP-4) inhibitor was referred to our hospital because of his refractory watery diarrhea. Ileocolonoscopy revealed increased capillary growth, fine granular mucosa, and longitudinal mucosal tears mainly in the left side of the colon. A bioptic examination revealed thickened subepithelial collagen bands, thus confirming the diagnosis of collagenous colitis. Systemic steroid therapy was initiated, but his symptoms recurred when tapering the steroid. However, withdrawal of the DPP-4 inhibitor was successful even after the cessation of steroid therapy. We therefore considered his collagenous colitis to have been caused by the DPP-4 inhibitor.

Abstract
BACKGROUND Eosinophilic oesophagitis (EoE) is an increasingly common cause of dysphagia in both children and adults, as well as one of the most prevalent oesophageal diseases with a significant impact on physical health and quality of life. We have provided a single comprehensive guideline for both paediatric and adult gastroenterologists on current best practice for the evaluation and management of EoE. METHODS The Oesophageal Section of the British Society of Gastroenterology was commissioned by the Clinical Standards Service Committee to develop these guidelines. The Guideline Development Group included adult and paediatric gastroenterologists, surgeons, dietitians, allergists, pathologists and patient representatives. The Population, Intervention, Comparator and Outcomes process was used to generate questions for a systematic review of the evidence. Published evidence was reviewed and updated to June 2021. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system was used to assess the evidence and make recommendations. Two rounds of voting were held to assess the level of agreement and the strength of recommendations, with 80% consensus required for acceptance. RESULTS Fifty-seven statements on EoE presentation, diagnosis, investigation, management and complications were produced with further statements created on areas for future research. CONCLUSIONS These comprehensive adult and paediatric guidelines of the British Society of Gastroenterology and British Society of Paediatric Gastroenterology, Hepatology and Nutrition are based on evidence and expert consensus from a multidisciplinary group of healthcare professionals, including patient advocates and patient support groups, to help clinicians with the management patients with EoE and its complications.

Abstract
The first part of this overview on non-neoplastic esophagus is focused on gastro-esophageal reflux disease (GERD) and Barrett’s esophagus. In the last 20 years much has changed in histological approach to biopsies of patients with gastro-esophageal reflux disease. In particular, elementary histologic lesions have been well defined and modality of evaluation and grade are detailed, their sensitivity and specificity has been evaluated and their use has been validated by several authors. Also if there is not a clinical indication to perform biopsies in patient with GERD, the diagnosis of microscopic esophagitis, when biopsies are provided, can be performed by following simple rules for evaluation which allow pathologists to make the diagnosis with confidence. On the other hand, biopsies are required for the diagnosis of Barrett’s esophagus. This diagnosis is the synthesis of endoscopic picture (which has to be provided with the proper description on extent and with adequate biopsies number) and histologic pattern. The current guidelines and expert opinions for the correct management of these diagnosis are detailed.

Abstract
BACKGROUND AND STUDY AIMS Eosinophilic oesophagitis (EoE) is a common disease with a significant impact on physical health and quality of life (QoL). Outcomes and management vary widely, with no agreed UK national guideline. This paper aims to describe an up-to-date description of demographics, clinical spectrum and outcomes for paediatric and adult patients with EoE from the North East of England between 2016 and 2019. PATIENTS AND METHODS Patients from two large University Hospitals and the specialist paediatric hospital for the North East of England with histologically or clinically confirmed EoE were included in this analysis. Data were collected retrospectively via electronic patient records. Remission was defined as either the resolution of symptoms or improvement on histology. RESULTS Data were collected on 74 paediatric and 59 adult patients. Dysphagia was the most common presenting symptom in both groups, accounting for 51%-84% of all presentations. Proton pump inhibitors and dietary manipulation were the most common therapies associated with remission in children (95% of those achieving remission), whereas the use of swallowed topical steroids was more prevalent in the treatment of adults (55% achieving remission). CONCLUSIONS EoE is a complex disease and poses significant challenges. Outcomes vary widely and need to be tailored to individual patient groups. Dietary manipulation plays a major role in treatment for EoE, but this is likely to be challenging for patients, especially children. Future work should continue to assess the outcomes in EoE, including on QoL and potential novel targeted therapies.

Abstract
Inflammatory bowel diseases (IBDs) are lifelong disorders in which an interaction between genetic and environmental factors is involved. IBDs include two entities: Crohn's disease (CD) and ulcerative colitis (UC); these can be adequately diagnosed and distinguished with a correct methodological approach based on communicating exhaustive clinical, endoscopic and laboratory information to the pathologist and performing adequate bioptic sampling and precise morphological signs including crypt architecture, distribution of inflammation and granulomas, when present. IBD needs to be distinguished from non-IBD colitis, mostly at its onset. Moreover, IBDs are associated with an increased risk of developing colorectal adenocarcinoma. In daily pathological practice, correct diagnosis of IBD and its subclassification as well as a correct detection of dysplasia is imperative to establish the best therapeutic approach.

Abstract
PURPOSE The diagnosis microscopic colitis (MC) consisting of collagenous colitis (CC) and lymphocytic colitis (LC) relies on histological assessment of mucosal biopsies from the colon. The optimal biopsy strategy for reliable diagnosis of MC is controversial. The aim of this study was to evaluate the distribution of histopathological features of MC throughout the colon. METHODS Mucosal biopsies from multiple colonic segments of patients with MC who participated in one of the three prospective European multicenter trials were analyzed. Histological slides were stained with hematoxylin-and-eosin, a connective tissue stain, and CD3 in selected cases. RESULTS In total, 255 patients were included, 199 and 56 patients with CC and LC, respectively. Both groups exhibited a gradient with more pronounced inflammation in the lamina propria in the proximal colon compared with the distal colon. Similarly, the thickness of the subepithelial collagenous band in CC showed a gradient with higher values in the proximal colon. The mean number of intraepithelial lymphocytes was > 20 in all colonic segments in patients within both subgroups. Biopsies from 86 to 94% of individual segments were diagnostic, rectum excluded. Biopsies from non-diagnostic segments often showed features of another subgroup of MC. CONCLUSION Conclusively, although the severity of the histological changes in MC differed in the colonic mucosa, the minimum criteria required for the diagnosis were present in the random biopsies from the majority of segments. Thus, our findings show MC to be a pancolitis, rectum excluded, questioning previously proclaimed patchiness throughout the colon.

Abstract
Most absorption of nutrients takes place in the proximal small intestine, and the most common disorders leading to malabsorption are associated with a morphological abnormality in the duodenal mucosa that is appreciable in histological sections of biopsy specimens. Coeliac disease is the most well-known example, causing intraepithelial lymphocytosis, inflammation and villous atrophy in the duodenum. Remarkably similar inflammatory changes can be induced by other processes, including medications, e.g. angiotensin II receptor blockers and immune checkpoint inhibitors, immune dysregulation disorders, e.g. common variable immunodeficiency and autoimmune enteropathy, infections, collagenous sprue, and tropical sprue. However, there are often subtle histological differences from coeliac disease in the type of inflammatory infiltrate, the presence of crypt apoptosis, and the extent and type of inflammation beyond the duodenum. The clinical setting and serological investigation usually allow diagnostic separation, but some cases remain challenging. Histopathology is also important in assessing the response to treatment, such as the change in villous architecture caused by a gluten-free diet, or the response to cessation of a potentially causative medication. This review examines the practical role that histopathology of duodenal biopsy specimens plays in the assessment and management of inflammatory malabsorptive processes of the proximal small intestine, with a particular emphasis on coeliac disease.

Abstract
OBJECTIVES Microscopic colitis (MC) is characterized by chronic diarrhea, normal colonoscopy findings, and mucosal inflammation in colonic biopsies and can be classified as collagenous colitis (CC) or lymphocytic colitis (LC). However, the pathogenesis of MC is largely unknown. In this study, we aimed to study mast cell counts and activation in MC. METHODS We investigated 64 biopsy samples from the surgical pathology database of Indiana University Health, which met the diagnostic criteria for CC or LC along with 20 control samples collected from 2014 to 2015. The specimens were used for the quantification of mast cells by examining the presence of intracellular and extracellular tryptase by immunohistochemistry. RESULTS In the lamina propria, the mast cell count was higher in both CC and LC groups than the control (mean highest count, 39/high-power field (HPF) vs. 30/HPF vs. 23/HPF; P < 0.01). Extracellular tryptase was present in 10% of control subjects as compared to 41% of CC (P < 0.01). Extracellular tryptase was present in 10% of control subjects as compared to 41% of CC (P < 0.01). Extracellular tryptase was present in 10% of control subjects as compared to 41% of CC (. CONCLUSIONS The increased mast cell count and degranulation are identified in MC, suggesting that mast cell activation might be involved in the pathogenesis of MC.

Abstract
Background Autoimmune metaplastic atrophic gastritis (AMAG) is an immune-mediated process that may lead to pernicious anemia (PA) and an increased risk of gastric cancer. Although some literature supports 3- or 5-year endoscopic surveillance for gastric cancer in patients with PA, no formal guidance exists for the general AMAG population. We sought to identify the prevalence and incidence rates of dysplasia or adenocarcinoma in patients with AMAG in order to clarify endoscopic best practices. Methods A retrospective study of 150 patients diagnosed with AMAG on endoscopic gastric biopsy between 1/2010 and 11/2015 was performed at a tertiary medical center. Clinical and pathologic data were obtained in order to calculate the prevalence and the incidence rate of dysplasia or adenocarcinoma. Results The cohort was predominantly female (82%) and white (61%), with median age 64 years. PA was present in 47% of patients. On index endoscopy, the prevalence of adenocarcinoma was 5.3%. A total of 59 patients with AMAG, but without neoplasia on initial biopsy, underwent subsequent endoscopic surveillance. Two patients, both of whom had confirmed PA, developed adenocarcinoma. The incidence rate of adenocarcinoma among this group was 14.2 cases per 1000 person-years, which far exceeds that of the general population (0.073 per 1000 person-years) based on Surveillance, Epidemiology, and End Results data. Conclusions AMAG is associated with a high prevalence and incidence of gastric cancer, and endoscopic surveillance should be considered. Prospective cohort studies and cost effectiveness analyses are needed to better estimate cancer risk and recommended endoscopic surveillance intervals in these patients.

Abstract
Background and study aims Although duodenal biopsy is considered the "gold standard" for diagnosis of celiac disease, the optimal location of biopsy within the small bowel for diagnosis remains unclear. The primary aim of this study was to perform a structured systematic review and meta-analysis to evaluate the diagnostic utility of endoscopic duodenal bulb biopsy for celiac disease. Patients and methods Searches of PubMed, EMBASE, Web of Science, and Cochrane Library databases were performed from 2000 through December 2017. Review of titles/abstracts, full review of potentially relevant studies, and data abstraction was performed. Measured outcomes of adult and pediatric patients included location of biopsy, mean number of biopsies performed, and diagnosis of celiac disease as defined by the modified Marsh-Oberhuber classification. Results A total of 17 studies (n = 4050) were included. Seven studies evaluated adults and 11 studies assessed pediatric populations. Mean age of adults and pediatric patients was 46.70 ± 2.69 and 6.33 ± 1.26 years, respectively. Overall, sampling from the duodenal bulb demonstrated a 5 % (95 % CI 3 - 9; P < 0.001) increase in the diagnostic yield of celiac disease. When stratified by pediatric and adult populations, duodenal bulb biopsy demonstrated a 4 % (95 % CI: 1 to 9; P < 0.001) and 8 % (95 % CI: 6 to 10; P < 0.001) increase in the diagnostic yield of celiac disease. Non-celiac histologic diagnoses including Brunner gland hyperplasia and peptic duodenitis were reported more commonly in the duodenal bulb as compared to the distal duodenum with an increase in diagnostic yield of 4 % (95 % CI 3 - 5; P < 0.001) and 1 % (95 % CI 1 - 2; P < 0.001), respectively. Conclusions Based upon our results, biopsy and histologic examination of duodenal bulb during routine upper endoscopy increases the diagnostic yield of celiac disease.

Quality standards in upper gastrointestinal endoscopy: a position statement of the British Society of Gastroenterology (BSG) and Association of Upper Gastrointestinal Surgeons of Great Britain and Ireland (AUGIS). Gut 2017; 66:1886-1899. [PMID: 28821598 PMCID: PMC5739858 DOI: 10.1136/gutjnl-2017-314109] [Citation(s) in RCA: 193] [Impact Index Per Article: 27.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2017] [Revised: 06/26/2017] [Accepted: 07/12/2017] [Indexed: 12/18/2022]
Abstract
This document represents the first position statement produced by the British Society of Gastroenterology and Association of Upper Gastrointestinal Surgeons of Great Britain and Ireland, setting out the minimum expected standards in diagnostic upper gastrointestinal endoscopy. The need for this statement has arisen from the recognition that while technical competence can be rapidly acquired, in practice the performance of a high-quality examination is variable, with an unacceptably high rate of failure to diagnose cancer at endoscopy. The importance of detecting early neoplasia has taken on greater significance in this era of minimally invasive, organ-preserving endoscopic therapy. In this position statement we describe 38 recommendations to improve diagnostic endoscopy quality. Our goal is to emphasise practices that encourage mucosal inspection and lesion recognition, with the aim of optimising the early diagnosis of upper gastrointestinal disease and improving patient outcomes.

Gastrointestinal symptom prevalence depends on disease duration and gastrointestinal region in type 2 diabetes mellitus. World J Gastroenterol 2017; 23:6694-6704. [PMID: 29085214 PMCID: PMC5643290 DOI: 10.3748/wjg.v23.i36.6694] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2016] [Revised: 03/12/2017] [Accepted: 06/01/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To unravel relationships between gastrointestinal (GI) symptoms impairing quality of life (QOL) and clinical profiles of diabetes mellitus (DM) patients.
METHODS We enrolled 134 outpatients with type 2 DM. Mean age was 64.7 years, mean body mass index was 24.7 kg/m2, mean glycated hemoglobin was 7.1%, and mean DM duration was 13.7 years. GI symptom-related QOL was determined using the Izumo scale, based on five factors, i.e., heartburn, gastralgia, postprandial fullness, constipation and diarrhea. The sum of scores obtained for the three questions in each domain was calculated, and subjects with a score of 5 or higher were considered to be symptomatic with impaired QOL. JMP Clinical version 5.0 was used for all statistical analyses.
RESULTS Lower abdominal symptoms were found to be more frequent than those affecting the upper abdomen. Diabetic duration and medications showed associations with GI symptoms. We identified differences in peak prevalences of the five symptoms. Gastralgia (P = 0.02 vs 10-14 years) and total GI symptoms (P = 0.01 and P = 0.02 vs 5-9 years and 10-14 years, respectively) peaked at a diabetes duration of 15-19 years. Heartburn (P = 0.004) and postprandial fullness (P = 0.03) tended to increase with disease duration. Constipation and diarrhea showed bimodal peaks, with the first early and the second late (e.g., P = 0.03 at 15-19 years vs 10-14 years for diarrhea) in the disease course. Finally, GI symptoms showed clustering that reflected the region of the GI tract affected, i.e., constipation and diarrhea had similar frequencies (P < 0.0001).
CONCLUSION Our study highlights the importance of questioning patients about QOL impairment due to abdominal symptoms, especially in the early and the late periods of diabetes.

Abstract
We describe an adult cohort with eosinophilic esophagitis (EoE) and evidence of celiac disease (CD), propose a change in diagnostic practice to better characterize these conditions, and hypothesize new directions for research. Pediatric studies postulate association between gluten sensitivity and EoE. However, few publications describe the prevalence, detection, or therapeutic and pathophysiologic implications of such association in adults. Retrospective chart review was done on patients diagnosed with EoE from 2009 to 2010 at University of Utah Hospitals and Clinics. Data included sex, age, presentation, duodenal pathology, tissue transglutaminase immunoglobulin A antibody (TTG) positivity, human leukocyte antigen (HLA) type (when indicated), and gross and microscopic Esophagogastroduodenoscopy (EGD) findings. Duodenal biopsy, TTG results, and HLA type were correlated. Endoscopy was repeated after gluten-free diet. Forty-four of 75 patients were followed in EoE specialty clinic with duodenal biopsy and TTG testing per protocol. Six EoE patients had potential or probable CD. No sex or age differences were noted between those with findings of CD and EoE and those with EoE alone. Six patients with findings of CD and EoE followed gluten-free diet. Five underwent repeat endoscopy. Three had resolution of esophageal eosinophilia. Potential or probable CD was commonly found in adults with EoE. Diagnosis of CD may be challenging due to nonspecific symptoms and insufficient duodenal biopsy and serologic testing. Furthermore, gluten-free diet resolved EoE findings in some patients, suggesting possible shared pathophysiology in some cases of EoE and CD. TTG testing and adequate duodenal biopsy may further direct clinical care for EoE patients, and studies are needed to elucidate mechanisms linking EoE and CD.

Abstract
Microscopic colitis (MC) is a chronic inflammatory bowel disease that has emerged in the last three decades as a leading cause of chronic watery diarrhoea. MC classically includes two main subtypes: lymphocytic colitis (LC) and collagenous colitis (CC). Other types of histopathological changes in the colonic mucosa have been described in patients with chronic diarrhoea, without fulfilling the conventional histopathological criteria for MC diagnosis. Whereas those unclassified alterations remained orphan for a long time, the use of the term incomplete MC (MCi) is nowadays universally accepted. However, it is still unresolved whether CC, LC and MCi should be considered as one clinical entity or if they represent three related conditions. In contrast to classical MC, the real epidemiological impact of MCi remains unknown, because only few epidemiological studies and case reports have been described. MCi presents clinical characteristics indistinguishable from complete MC with a good response to budesonide and cholestiramine. Although a number of medical treatments have been assayed in MC patients, currently, there is no causal treatment approach for MC and MCi, and only empirical strategies have been performed. Further studies are needed in order to identify their etiopathogenic mechanisms, and to better classify and treat MC.

Abstract
Despite the relatively high frequency of gastrointestinal (GI) disorders in individuals with type 1 diabetes (T1D), termed diabetic enteropathy (DE), the pathogenic mechanisms of these disorders remain to be elucidated. While previous studies have assumed that DE is a manifestation of diabetic autonomic neuropathy, other contributing factors such as enteric hormones, inflammation, and microbiota were later recognized. More recently, the emerging role of intestinal stem cells (ISCs) in several GI diseases has led to a new understanding of DE. Given the absence of diagnostic methods and the lack of broadly efficacious therapeutic remedies in DE, targeting factors and pathways that control ISC homeostasis and are dysfunctional in DE may represent a new path for the detection and cure of DE.

Abstract
Collagenous colitis (CC) is an increasingly recognized cause of chronic inflammatory bowel disease characterized by watery non-bloody diarrhea. As a lesser studied inflammatory bowel disease, many aspects of the CC's natural history are poorly understood. This review discusses strategies to optimally manage CC. The goal of therapy is to induce clinical remission, <3 stools a day or <1 watery stool a day with subsequent improved quality of life (QOL). Antidiarrheal can be used as monotherapy or with other medications to control diarrhea. Budesonide therapy has revolutionized treatment and is superior to prednisone, however, the treatment is associated with high-relapse rates and the management of refractory disease is challenging. Ongoing trials will address the safety and efficacy of low-dose maintenance therapy. For those with refractory disease, case reports and case series support the role of biologic agents. Diversion of the fecal stream normalizes colonic mucosal changes and ileostomy may be considered where anti-tumor necrosis factor (TNF)-α agents are contraindicated. Underlying celiac disease, bile salt diarrhea, and associated thyroid dysfunction should be ruled out. The author recommends smoking cessation as well as avoidance of nonsteroidal anti-inflammatories as well as other associated medications.

Abstract
BACKGROUND Microscopic colitis (MC) is an underdiagnosed inflammatory bowel disease. AIM To develop an evidence-based clinical practice guide on MC current concepts. METHODS Literature search was done on the Cochrane Library, EMBASE and MEDLINE electronic databases, which were consulted covering the period up until March 2015. Work groups were selected for each of the reviewed topics, with the purpose of drafting the initial statements and recommendations. They subsequently underwent a voting process based on the Delphi method. Each statement/recommendation was accompanied by the result of the vote the level of evidence, and discussion of the corresponding evidence. The grade of recommendation (GR) using the GRADE approach was established for diagnosis and treatment recommendations. RESULTS Some key statements and recommendations are: advancing age increases the risk of developing MC, mainly in females. The symptoms of MC and IBS-D may be similar. If MC is suspected, colonoscopy taking biopsies is mandatory. Treatment with oral budesonide is recommended to induce clinical remission in patients with MC. Oral mesalazine is not recommended in patients with collagenous colitis for the induction of clinical remission. The use of anti-TNF-alpha drugs (infliximab, adalimumab) is recommended for the induction of remission in severe cases of MC that fail to respond to corticosteroids or immunomodulators, as an alternative to colectomy. CONCLUSIONS This is the first consensus paper on MC based on GRADE methodology. This initiative may help physicians involved in care of these patients in taking decisions based on evidence.

Abstract
Background and Aims. Upper endoscopy is a valuable tool in the workup of gastrointestinal (GI) complaints. The purpose of this study is to determine cost and yield of taking biopsies in a normal upper GI tract. Methods. This is a retrospective study where all upper GI biopsies were identified between May 2012 and April 2013, at a tertiary care center. Clinical, procedural, and pathology reports were reviewed to identify patient demographics, procedure information, and pathology diagnosis. Results. Biopsies of the upper GI tract were taken in 1297 patients with normal upper endoscopies. In patients with normal upper endoscopy, 22% of esophageal, 44% of gastric, and 12% of duodenal biopsies were abnormal. The most frequent abnormality was reflux esophagitis in 16% of esophageal biopsies, chronic gastritis in 23% of gastric biopsies, and increased intraepithelial lymphocytes in 6% of duodenal biopsies. The additional cost for taking biopsies in a normal upper GI tract for a diagnosis of eosinophilic esophagitis was $2963 Canadian (CAD), H. pylori associated gastritis was $1404 CAD, and celiac disease was $3024 CAD. Conclusions. The yield of biopsy in normal upper endoscopy varied with location, but the additional expense can be costly and should be tailored to appropriate clinical situations.

Abstract
Microscopic colitis is a common cause of chronic diarrhea. It is characterized by non-bloody watery diarrhea with macroscopically normal colonic mucosa. Its specific histological characteristics confirm the diagnosis. Two distinct histological forms can be identified, namely, collagenous colitis and lymphocytic colitis. In collagenous colitis, a thick colonic subepithelial collagenous deposit can be observed, whereas in lymphocytic colitis, a pronounced intraepithelial lymphocytic inflammation in the absence of a thickened collagen band can be identified. Microscopic colitis occurs more frequently in elderly females and its etiology is believed to be multifactorial, although smoking and consumption of several drugs have been identified as risks factors for the development of the disease. The treatment is based on avoiding the risks factors and administration of oral budesonide.

Abstract
Confirmation of endoscopically suspected esophageal metaplasia (ESEM) requires histology, but confusion in the histological definition of columnar-lined esophagus (CLE) is a longstanding problem. The aim of this study is to evaluate interpathologist variability in the interpretation of CLE. Thirty pathologists were invited to review three ten-case sets of CLE biopsies. In the first set, the cases were provided with descriptive endoscopy only; in the second and the third sets, ESEM extent using Prague criteria was provided. Moreover, participants were required to refer to a diagnostic chart for evaluation of the third set. Agreement was statistically assessed using Randolph's free-marginal multirater kappa. While substantial agreement in recognizing columnar epithelium (K = 0.76) was recorded, the overall concordance in clinico-pathological diagnosis was low (K = 0.38). The overall concordance rate improved from the first (K = 0.27) to the second (K = 0.40) and third step (K = 0.46). Agreement was substantial when diagnosing Barrett's esophagus (BE) with intestinal metaplasia or inlet patch (K = 0.65 and K = 0.89), respectively, in the third step, while major problems in interpretation of CLE were observed when only cardia/cardia-oxyntic atrophic-type epithelium was present (K = 0.05-0.29). In conclusion, precise endoscopic description and the use of a diagnostic chart increased consistency in CLE interpretation of esophageal biopsies. Agreement was substantial for some diagnostic categories (BE with intestinal metaplasia and inlet patch) with a well-defined clinical profile. Interpretation of cases with cardia/cardia-oxyntic atrophic-type epithelium, with or without ESEM, was least consistent, which reflects lack of clarity of definition and results in variable management of this entity.

Abstract
BACKGROUND AND AIMS The histopathological discrimination of Crohn's disease [CD] and ulcerative colitis [UC] can be challenging. The aim of this study was to evaluate if quantification of CD30(+) lymphocytes and eosinophils in histopathological material improves the accuracy of diagnosis of inflammatory bowel disease. METHODS A total of 156 patients were diagnosed with IBD by a gastroenterologist and corroborated by 5 years of follow-up. Patients were treatment naïve at the time of biopsy. Samples were taken from diseased areas of the colon and examined by a gastrointestinal pathologist. RESULTS The median number of eosinophils in biopsies from affected segments was 42/high power field [hpf] [25.5-63.5] in CD and 98/hpf [67-123] in UC [p < 0.001]. Biopsies containing ≥ 70 eosinophils/hpf field had a sensitivity of 78.3% and a specificity of 71% for the diagnosis of UC ({area under the receiver operating characteristic (ROC) curve 0.767 (95% confidence interval [CI] 0.696-0.838)}. There was a median of three CD30(+) cells/hpf [range 2-6] in diseased CD biopsies and 33 cells/hpf [24-52] in diseased UC biopsies [p < 0.001]. The cut-off determined by the ROC curve was 15 (sensitivity 97.4%, specificity 97.4%, positive likelihood ratio (PLR) 17.1, Negative likelihood ratio (NLR) 0.03, area under the curve [AUC]: 0.978; 95% CI 0.95310.999). CONCLUSIONS Routine histopathological assessment with quantification of CD30+ cells is highly accurate at discriminating CD and UC. All the measured parameters are easy to perform, low-cost, and available in most pathological laboratories.

Abstract
Microscopic colitis has emerged as a major cause of chronic watery non-bloody diarrhoea, particularly in elderly females. The term is used as an umbrella term to categorize a subgroup of colitides with distinct clinicopathological phenotypes and no significant endoscopic abnormalities. Lymphocytic colitis is defined by an increased number of surface intraepithelial lymphocytes, and collagenous colitis by a thickened collagen band underneath the surface epithelium. There is increased inflammation in the lamina propria, but only little or no crypt architectural distortion. Incomplete and variant forms showing less characteristic features have been reported under different names. The differential diagnosis mainly includes resolving infectious colitis and changes related to the intake of drugs such as non-steroidal anti-inflammatory drugs. Substantial clinical and histological overlap between lymphocytic and collagenous colitis has been described, raising the suspicion that the conditions are two histological manifestations of the same entity, possibly representing different manifestations during the disease course or different stages of disease development. In this review, we provide a practical approach for pathologists, with a focus on diagnostic criteria and differential diagnosis, and discuss recent insights into the pathogenesis of disease and the relationship with classic chronic inflammatory bowel disease, i.e. Crohn's disease and ulcerative colitis.

[PMID: 24931895 DOI: 10.1016/j.crohns.2014.05.003] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2014] [Revised: 04/10/2014] [Accepted: 05/19/2014] [Indexed: 02/06/2023]
Abstract
BACKGROUND Although it is usually not difficult to diagnose inflammatory bowel disease (IBD) on surgical resection specimens, difficulties sometimes arise in differentiating these entities from other forms of colitis on endoscopic biopsy specimens. Basal plasmacytosis is considered as an early feature of IBD colitis, but it is rare in non-IBD colitides. AIMS We assessed the value of basal plasmacytosis as an individual variable in untreated patients with colitis. PATIENTS AND METHODS Archival slides of patients with untreated colitis (66 IBD and 49 non-IBD) and 20 controls with complete (from the terminal ileum to the rectum) endoscopic biopsy sampling were evaluated blindly for the presence of basal plasmacytosis and a possible association with the presence of eosinophils in the same anatomical location. RESULTS Overall, basal plasmacytosis was present in at least one anatomical segment in 58% of cases, and it was always present in patients with IBD, whereas it was sparsely found (9%) in patients with other colitides and in controls. Basal plasmacytosis in three or more segments had more than 80% probability for a patient to be classified as IBD, with the segmental distribution being different between ulcerative colitis and Crohn's disease. Additionally, basal plasmacytosis was always accompanied by eosinophils intermingled with plasma cells in the same anatomical position. CONCLUSION As an individual feature, basal plasmacytosis (accompanied by eosinophils) is a strong feature suggesting IBD, particularly when present in three or more colonic segments. This fact may be useful in the evaluation of endoscopic biopsies from patients with "colitis".

Abstract
Lower gastrointestinal endoscopy is a commonly undertaken procedure and has assumed even greater prominence with the inception of the NHS Bowel Cancer Screening Programme (BCSP). Workloads are also constantly increasing within histopathology departments and this has led to a need for workload management by laboratories. Advanced endoscopic techniques now allow for targeted biopsies within settings such as inflammatory bowel disease surveillance and the BCSP. In this article, we provide guidance to the endoscopist for optimal biopsy protocols that are designed to maximise the chance of a subsequent histopathological examination providing definitive results and to reduce the number of unnecessary biopsies, in which histopathology is unlikely to deliver clinically useful information. The majority of the article focuses on biopsy taking within a defined range of clinical situations that are commonly encountered by endoscopists.

Abstract
BACKGROUND Esophageal linear furrows, corrugated rings, and/or white exudates are often seen in patients with eosinophilic esophagitis (EoE); however, whether these are specific to EoE remains unclear. Endoscopic surveillance of these features was conducted to determine whether these represent esophageal eosinophilia, which is essential for the diagnosis of EoE. PATIENTS AND METHODS Two thousand seven hundred and sixty-three patients were enrolled consecutively. Target biopsy was carried out when the above features were seen. Histological eosinophilia was defined as 24 or more eosinophils per high-power field (HPF). Associations between features and eosinophilia were analyzed statistically. RESULTS Two thousand five hundred and forty-five patients completed the study. Linear furrows, corrugated rings and white exudates were seen in 24, 15 and 45 patients, respectively. These findings somewhat overlapped. Among 58 biopsied patients withany of the above features, these features represented eosinophilia in 14% (3/21), 23% (3/13), and 5% (2/43), respectively. None of the 199 patients who received biopsy for other features had eosinophilia. Two of five eosinophilia patients were diagnosed with EoE. Multiple comparisons revealed that eosinophil counts in linear furrows and corrugated rings but not white exudates were significantly greater than those in other features (12, 9, 1, and <1 eosinophils/HPF on average, respectively). CONCLUSIONS An endoscopic feature suggesting EoE does not always represent esophageal eosinophilia and is non-specific for EoE, although it reminds endoscopists of the presence of EoE. The diagnostic utility of linear furrows or corrugated rings for esophageal eosinophilia is superior to that of white exudates.

Abstract
OBJECTIVES Two prior studies suggested that coeliac disease (CD) has a higher prevalence rate (8%) in SSc than in the general population (1%), but these studies were limited by small numbers and the use of traditional coeliac screening antibody tests, where newer ones with improved accuracy have since emerged. Our aim was to determine the prevalence of CD in a larger SSc population using a more modern serological approach to coeliac testing and to correlate coeliac antibody status with gastrointestinal symptoms. METHODS Stored sera from 72 SSc patients in the Scleroderma Registry at the Hospital for Special Surgery were tested for anti-tissue transglutaminase (traditional) and anti-deamidated gliadin peptide (novel) antibodies. If any of these antibodies were positive, anti-endomysial antibodies were tested and confirmatory small-bowel endoscopy and biopsy were obtained. Registry clinical data were used to determine whether antibody status correlated with gastrointestinal symptoms. RESULTS The prevalence of coeliac antibodies in our SSc population was 3/72 (4%). No significant differences with respect to gastrointestinal symptoms were seen in the coeliac antibody-positive compared with -negative SSc patients. No cases of confirmed CD were seen in our cohort. CONCLUSION Contrary to the only two previously published studies, the low prevalence of CD that we found does not suggest that concurrent CD is a common cause of gastrointestinal complaints in SSc patients.

Abstract
Irritable bowel syndrome (IBS) is a common gastrointestinal (GI) disorder that considerably reduces the quality of life. It further represents an economic burden on society due to the high consumption of healthcare resources and the non-productivity of IBS patients. The diagnosis of IBS is based on symptom assessment and the Rome III criteria. A combination of the Rome III criteria, a physical examination, blood tests, gastroscopy and colonoscopy with biopsies is believed to be necessary for diagnosis. Duodenal chromogranin A cell density is a promising biomarker for the diagnosis of IBS. The pathogenesis of IBS seems to be multifactorial, with the following factors playing a central role in the pathogenesis of IBS: heritability and genetics, dietary/intestinal microbiota, low-grade inflammation, and disturbances in the neuroendocrine system (NES) of the gut. One hypothesis proposes that the cause of IBS is an altered NES, which would cause abnormal GI motility, secretions and sensation. All of these abnormalities are characteristic of IBS. Alterations in the NES could be the result of one or more of the following: genetic factors, dietary intake, intestinal flora, or low-grade inflammation. Post-infectious IBS (PI-IBS) and inflammatory bowel disease-associated IBS (IBD-IBS) represent a considerable subset of IBS cases. Patients with PI- and IBD-IBS exhibit low-grade mucosal inflammation, as well as abnormalities in the NES of the gut.

Abstract
Diarrhea is a common clinical feature of inflammatory bowel diseases and may be accompanied by abdominal pain, urgency, and fecal incontinence. The pathophysiology of diarrhea in these diseases is complex, but defective absorption of salt and water by the inflamed bowel is the most important mechanism involved. In addition to inflammation secondary to the disease, diarrhea may arise from a variety of other conditions. It is important to differentiate the pathophysiologic mechanisms involved in the diarrhea in the individual patient to provide the appropriate therapy. This article reviews microscopic colitis, ulcerative colitis, and Crohn's disease, focusing on diarrhea.

Abstract
Collagenous and lymphocytic colitis are common causes of chronic watery diarrhea that are characterized by distinct histopathologic abnormalities without endoscopically visible lesions and are summarized as microscopic colitis. Several variants of microscopic colitis have been described, although their clinical significance still has to be defined. Preserved mucosal architecture is a histologic hallmark of microscopic colitis and distinguishes the disease from inflammatory bowel disease (IBD). In addition to architectural abnormalities, the diagnosis of IBD rests on characteristic inflammatory changes. Differential diagnosis of IBD mainly includes prolonged infection and diverticular disease-associated colitis, also known as segmental colitis associated with diverticulosis.

Abstract
PURPOSE Eosinophilic esophagitis (EoE) is a chronic disease characterized by eosinophilic infiltration of the esophageal mucosa, which is associated with clinical and endoscopic manifestations. The objective of our study was to determine the frequency of EoE and to outline the clinical manifestations of EoE in Polish children. MATERIAL/METHODS Ten large regional pediatric gastroenterology centers participated in the study. A database of endoscopy reports from January 2004 till December 2009 was reviewed. A total of 35,631 esophagogastroduodenal endoscopy studies in children, aged from 4 months to 18 years, were performed. Data pertaining to the children's age, gender, indications for endoscopy, clinical findings and histopathology diagnosis were made. RESULTS In 84 children (20 girls and 64 boys), aged between 4 months and 18 years, EoE was diagnosed. This constituted one case per 424 endoscopic studies. In children with changes in the esophageal mucosa the frequency of EoE was higher and reached one case per 73 children. The most frequent symptoms of EoE differed between the younger (1-6 years old) and older children (aged 13-18 years old). Feeding aversion, vomiting and/or regurgitation were most frequently observed in the younger children, while in older children: abdominal pain, dysphagia and chest pain. Granular mucosa, longitudinal furrows, and mucosal rings belong to the findings most often observed in endoscopic studies. EoE was more frequently diagnosed in the spring (45.2%) and summer (28.5%). CONCLUSIONS EoE was diagnosed in every age, with frequency of 1/424 gastrointestinal endoscopies, more frequently in boys than in girls.

Abstract
The main histologic feature of celiac disease is increased intraepithelial lymphocytes (IELs) with or without villous atrophy of the duodenal mucosa. The aim of this study was to document a broad range of additional morphologic changes in intestinal mucosa biopsy specimens from patients with celiac disease. Our cohort comprised 150 patients with positive tissue transglutaminase serologic findings; 7 were at Corazza stage A1, 58 at stage B1, and 85 at stage B2. IEL counts per 100 epithelial cells ranged from 34 to 156 (mean, 88.6); a significant neutrophilic infiltrate was present in 85 cases (56.7%); eosinophil count ranged from 3 to 50 per high-power field (mean, 14.6). Additional findings included morphologic changes in enterocytes in 68.7%, subepithelial collagen thickening in 45.3%, and associated lymphocytic gastritis in 30.4% of patients. We demonstrated that these underrecognized features, which can be misleading, are not uncommon in celiac disease and were positively associated with more advanced stages of the disease (P < .0001).

Abstract
BACKGROUND Nonresponsive celiac disease (CD) is defined by persistent or recurrent symptoms, common after treatment with a gluten-free diet (GFD). OBJECTIVE To evaluate the utility of capsule endoscopy (CE) in nonresponsive CD. DESIGN Case-control study. SETTING Tertiary-care center. PATIENTS Forty-two consecutive patients with nonresponsive CD and 84 age- and sex-matched CD-free controls who underwent CE were included. In addition, capsules taken after treatment with a GFD were retrospectively evaluated in 30 patients with uncomplicated CD. INTERVENTION CE. MAIN OUTCOME MEASUREMENTS Diagnostic accuracy of CE for the detection of mucosal abnormalities in nonresponsive CD. RESULTS Macroscopic features of villous atrophy were detected in 13 of 42 patients (31%) with nonresponsive CD compared with none among 84 CD-free controls and 14 of 30 patients (47%) with uncomplicated CD. Among nonresponsive CD cases, the overall sensitivity and specificity of CE for the detection of any degree of villous atrophy as graded by histology were 56% and 85%, respectively. Single or multiple erosions/ulcerations of the gut were observed in 19% of nonresponsive CD patients, 18% of CD-free controls, and 31% of patients with uncomplicated CD (P = .35). The presence of erosions/ulcerations was associated with increased aspirin/nonsteroidal anti-inflammatory drug use in nonresponsive CD (P =.05). Two severe complications (ulcerative jejunitis and adenocarcinoma) were detected by CE in nonresponsive CD. LIMITATIONS Single-center, retrospective study. CONCLUSIONS Mucosal abnormalities were observed by CE in patients with both nonresponsive CD and uncomplicated CD. CE can detect severe complications in patients with nonresponsive CD.

Abstract
Eosinophilic esophagitis (EoE) now represents a commonly recognized disorder among both pediatric and adult patients presenting to allergy and gastroenterology clinics throughout the world. The consequences of this localized and eosinophil-predominant inflammation of the esophagus can have an outsized and profound systemic and emotional impact for patients and their families. Unlike gastroesophageal reflux disease (GERD), whose symptoms closely overlap with those of EoE, EoE represents a primarily antigen-driven disorder whose symptoms and pathology are therapeutically mitigated with either long-term dietary control or chronic steroid therapies, rather than the acid-suppressive medications that are the mainstay of GERD treatment. Beyond the dissimilarities in their responses to treatment, these disorders are distinct in their gene expression profiles, heredity, genetic underpinning, and linkage with atopy. The antigen-driven nature of EoE has been reinforced by the remarkable impact of therapies utilizing elemental formulas to control the disease as well as a number of reports linking aeroallergens to seasonal worsening of disease.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is a chronic functional bowel disorder. The frequency of microscopic colitis and focal active colitis in the colonic mucosa has been investigated in IBS patients. METHODS Between June 2007 and September 2010, 378 patients (between 16 and 84 years) were recruited prospectively. Of these 378 patients, 226 patients were diagnosed with IBS using the Rome III criteria. 152 control patients were also enrolled who were undergoing colonoscopy for colorectal cancer screening or investigation of anemia. Histopathological abnormalities identified during colonoscopy were compared between the IBS and control groups. RESULTS The average age of the IBS group was 46.13 ± 14.16 years and and the average age of the control group was 57.01 ± 13.07 years. The prevalence of microscopic colitis (MC) in the diarrhea predominant and the mixed subgroup of IBS patients was 4.32% (7/162) whereas in all IBS patients, the prevalence was 3.09% (7/226). MC was not found in the 152 control cases, (p = 0.045). Lymphocytic colitis was seen in 7 IBS patients, with 1 case in the mixed group and 6 cases in the diarrhea group and there was a significant difference in the frequency of lymphocytic colitis between the IBS subgroups (p < 0.01). Focal active colitis was found in 6.6% (15/226) of the IBS patients and in none of the controls (p < 0.01), and there was no differences between IBS subtypes. CONCLUSION Microscopic colitis was more often found in the diarrhea predominant/mixed subgroups of IBS patients and in patients who were older women. In patients who are older woman with non-constipated IBS, it may be reasonable to perform a biopsy to screen for microscopic colitis. Focal active colitis was significantly increased in patients with IBS compared to controls.

Abstract
BACKGROUND Celiac disease (CD) is common but underdiagnosed in the United States. A proposed quality guideline recommends that ≥4 specimens be submitted during duodenal biopsy. The degree of adherence to this recommendation in clinical practice is unknown. OBJECTIVE To measure the number of specimens submitted during duodenal biopsy among patients throughout the United States and to determine the incremental diagnostic yield of adherence to the recommended number of specimens. DESIGN Retrospective cohort study. PATIENTS This study involved 132,352 patients without known CD who underwent duodenal biopsy. INTERVENTION Duodenal biopsy. MAIN OUTCOME MEASUREMENTS Duodenal biopsy specimens were submitted to a pathology laboratory operating in 43 states in the United States. We used multivariate logistic regression to identify factors associated with submitting ≥4 specimens. We also compared the prevalence of newly diagnosed CD in biopsies with ≥4 specimens with that in biopsies with <4 specimens. RESULTS Of the 132,352 patients who underwent biopsy (67% women, mean age 52.9 years), ≥4 specimens were submitted in 45,995 cases (35%). A modest increase in the proportion of biopsies with ≥4 specimens occurred after this guideline was proposed in 2006 (odds ratio for 2009 vs 2006, 1.51; 95% confidence interval, 1.22-1.88), but the rate of adherence in 2009 remained low at 37%. Among patients in whom the indication was malabsorption/suspected CD (n = 3261), adherence to this standard was only 39.5%. The probability of a new diagnosis of CD was increased when ≥4 specimens were submitted (1.8% vs 0.7%; P < .0001). LIMITATIONS Retrospective analysis lacking clinical follow-up. The guideline publication occurred during the study period, possibly influencing clinical practice and confounding results. CONCLUSION Although this proposed standard remains a subject of debate, adherence to submitting ≥4 specimens is low in the United States. Adherence yields a diagnosis rate of 1.8%, a small absolute increase but a doubling of the diagnosis rate of CD. Efforts to increase adherence are warranted.

Abstract
BACKGROUND An association between microscopic colitis and coeliac disease (CD) has been suggested in literature; however, population-based data are limited. AIMS To estimate the degree of association between these two diseases and to identify possible risk factors for disease concomitance. METHODS A population-based review of all patients diagnosed with CD and microscopic colitis in a large Canadian centre over a 5-year period. Endoscopy and pathology databases were searched to identify all cases of CD and microscopic colitis diagnosed within the Calgary Health Region between 2004 and 2008. Incidence rates were age-standardised and gender-standardised to 2006 Canadian Census data. standardised incidence ratios (SIR) were used to assess disease concomitance. RESULTS Over 5 years, 763 patients were diagnosed with CD, and 1106 were diagnosed with microscopic colitis. The standardised incidence of CD ranged from 10.4 to 15.7 per 100,000 population. The standardised incidence of microscopic colitis ranged from 16.9 to 26.2 per 100,000 population. Forty patients were diagnosed with both CD and microscopic colitis, 21 of whom were middle aged (40-60 years) females. Within the CD cohort, microscopic colitis occurred at an annual rate of 11.4 per 1000 cases of CD with an overall SIR of 52.7. CONCLUSIONS There exists a strong association between microscopic colitis and CD with disease concomitance being approximately 50-times that expected in the general population. The concomitant diagnosis of CD and microscopic colitis largely occurs in middle-aged women. Therefore, middle-aged women with CD and diarrhoea as a presenting or persistent symptom should undergo lower endoscopy with biopsies to rule out microscopic colitis.

Eosinophilic esophagitis: updated consensus recommendations for children and adults. J Allergy Clin Immunol 2011; 128:3-20.e6; quiz 21-2.

Abstract
Eosinophilic esophagitis (EoE) is a clinicopathologic condition of increasing recognition and prevalence. In 2007, a consensus recommendation provided clinical and histopathologic guidance for the diagnosis and treatment of EoE; however, only a minority of physicians use the 2007 guidelines, which require fulfillment of both histologic and clinical features. Since 2007, the number of EoE publications has doubled, providing new disease insight. Accordingly, a panel of 33 physicians with expertise in pediatric and adult allergy/immunology, gastroenterology, and pathology conducted a systematic review of the EoE literature (since September 2006) using electronic databases. Based on the literature review and expertise of the panel, information and recommendations were provided in each of the following areas of EoE: diagnostics, genetics, allergy testing, therapeutics, and disease complications. Because accumulating animal and human data have provided evidence that EoE appears to be an antigen-driven immunologic process that involves multiple pathogenic pathways, a new conceptual definition is proposed highlighting that EoE represents a chronic, immune/antigen-mediated disease characterized clinically by symptoms related to esophageal dysfunction and histologically by eosinophil-predominant inflammation. The diagnostic guidelines continue to define EoE as an isolated chronic disorder of the esophagus diagnosed by the need of both clinical and pathologic features. Patients commonly have high rates of concurrent allergic diatheses, especially food sensitization, compared with the general population. Proved therapeutic options include chronic dietary elimination, topical corticosteroids, and esophageal dilation. Important additions since 2007 include genetic underpinnings that implicate EoE susceptibility caused by polymorphisms in the thymic stromal lymphopoietin protein gene and the description of a new potential disease phenotype, proton pump inhibitor-responsive esophageal eosinophila. Further advances and controversies regarding diagnostic methods, surrogate disease markers, allergy testing, and treatment approaches are discussed.

Abstract
BACKGROUND The optimal endoscopic investigation of diarrhea in patients under age 50 without specific features of right-sided colonic/ileal disease is inadequately defined. OBJECTIVE To assess the potential additional yield of colonoscopy over flexible sigmoidoscopy (FS) in this group. DESIGN Retrospective cohort study. SETTING Two teaching hospital endoscopy units. PATIENTS This study involved all patients under age 50 who had a colonoscopy between 1997 and 2007 to investigate diarrhea, without high-risk features of right-sided colonic/ileal disease, inflammatory bowel disease (IBD), or rectal bleeding. INTERVENTION Colonoscopy and biopsy. MAIN OUTCOME MEASUREMENTS Diagnostic yield of colonoscopy over FS with biopsy. RESULTS Colonoscopic appearances were abnormal in 126 of 625 eligible patients (20%); 72% of abnormalities were within reach of FS. The most common endoscopic abnormality was suspected inflammation in 60 patients (10% overall), reportedly confined to the proximal colon or ileum in 22 patients (37% of this group). Histology from areas of suspected inflammation revealed features of IBD in 68% of patients, but results were normal in the remainder. In the 22 patients with suspected isolated proximal disease, 8 patients (36%) had normal histology results, and a further 6 had left-side colon biopsies demonstrating IBD. In patients with macroscopically normal colons, histological evidence of IBD or microscopic colitis occurred in 14 and 12 patients, respectively, with changes in the left side of the colon in 93% of patients. In this patient group, 85% of IBD or microscopic colitis could have been detected by FS and biopsy. The negative predictive value of FS with biopsy was 98% for IBD and 99% for microscopic colitis. LIMITATIONS Retrospective study. CONCLUSION FS is adequate for the investigation of diarrhea in patients under age 50 who lack other features, but its yield depends on biopsy of the left side of the colon.

Abstract
Gastro-esophageal reflux disease (GERD) is the most common digestive disease in industrialized countries (Europe and North America) and is associated with microscopic changes in the squamous epithelium. However, biopsy is not presently included in the routine diagnostic flow chart of GERD. In contrast, esophageal biopsy is mandatory when diagnosing Barrett's esophagus. High quality histology reports are necessary to provide information on diagnosis and can also be important for research and epidemiological studies. It has been evident for decades that pathology reports vary between institutions and even within a single institution. Standardization of reporting is the best way to ensure that information necessary for patient management is included in pathology reports. This paper details the histological criteria for diagnosing GERD-associated microscopic esophagitis, other forms of esophagitis with specific features and columnar metaplasia in the lower esophagus (Barrett's esophagus). It provides a detailed description of appropriate sampling criteria, individual lesions and how they contribute to the histology report.

Abstract
The incidence of chronic idiopathic inflammatory bowel diseases (IBD) is growing in western countries, making their histological diagnosis an everyday task for all pathologists. Reviews from the literature strongly suggest that such diagnosis cannot be performed on the histological ground alone but requires a clinical-pathological approach. Moreover, bewildering variations can be observed in the terminology employed to report either individual lesions or diagnostic categories. The aim of the present paper is to suggest a practical diagnostic algorithm summarizing the main data from the literature. Particular emphasis has been placed on minimum clinical information required and the accurate definition of individual lesions. Diagnostic categories to employ and to avoid in daily practice have furthermore been stressed.

Abstract
Coeliac disease is increasing in prevalence, which is currently estimated at one in 100 of the population and may occur de novo in adults. The diagnosis requires a joint clinicopathological approach; the recommended first-line test is serology with immunoglobulin A (IgA) tissue transglutaminase and IgA endomysial antibodies. These serological tests show high levels of sensitivity and specificity, but biopsy is the gold standard to confirm the diagnosis. It is important that both tests are performed before the introduction of a gluten-free diet. Although the classical histopathology changes of coeliac disease with partial or total villous atrophy are well recognized, the pathology classification of coeliac disease is changing, with recognition that coeliac disease may show minimal pathology (normal architecture and an intraepithelial lymphocyte count/100 enterocytes ≥ 25). This entity is also described as lymphocytic duodenosis, and recommendation of follow-up serology testing is paramount in this condition. Follow-up of patients with coeliac disease is warranted, as normal serology does not predict mucosal recovery. Failure to heal predicts risk of progression to refractory coeliac disease and malignancies. Refractory coeliac disease occurs in 1-2% of patients and this diagnosis requires a combined clinical and histopathology approach with immunocytochemistry.

Abstract
Eosinophil-associated gastrointestinal disorders (EGIDs) are uncommon conditions whose aetiologies are unclear, but which are characterised by eosinophilic infiltration and inflammation of the gastrointestinal tract in the absence of other causes of eosinophilia. We report the case of a 65-year-old woman with eosinophilic gastritis who underwent a Polya gastrectomy for a suspected gastric tumour with gastric outflow obstruction. Subsequent histological examination showed a non-malignant transmural eosinophilic infiltration of the stomach wall, a rare pathological entity. We present a review of the literature and discuss the management of such cases.
