Abstract
BACKGROUND Inflammatory Bowel Diseases (IBD) are known to occur in association with Hirschsprung disease (HSCR). Most of cases are represented by Crohn Disease (CD) occurring in patients with Total Colonic Aganglionosis (TCSA) with an estimated prevalence of around 2%. Based on these considerations and on a number of provisional data belonging to our Center for Digestive Diseases, we developed a unicentric cross-sectional observational study aimed at describing phenotype, genotype, pathology and metagenomics of all patients with TCSA and Crohn-like lesions. RESULTS Out of a series of 62 eligible TCSA patients, 48 fulfilled inclusion criteria and were enrolled in the study. Ten patients did not complete the study due to non-compliance or withdrawal of consent and were subsequently dropped out. A total of 38 patients completed the study. All patients were tested for chronic intestinal inflammation by a combination of fecal calprotectine (FC) or occult fecal blood (OFB) and underwent fecal metagenomics. Nineteen (50%) tested positive for FC, OFB, or both and subsequently underwent retrograde ileoscopy. Fourteen patients (36.8%) presented Crohn-like lesions, occurring after a median of 11.5 years after surgery (range 8 months - 21.5 years). No statistically significant differences regarding demographic, phenotype and genotype were observed comparing patients with and without lesions, except for need for blood transfusion that was more frequent in those with lesions. Faecal microbiome of patients with lesions (not that of caregivers) was less biodiverse and characterized by a reduction of Bacteroidetes, and an overabundance of Proteobacteria. FC tested negative in 3/14 patients with lesions (21%). CONCLUSIONS Our study demonstrated an impressive 10-folds higher incidence of chronic inflammation in TCSA. Up to 50% of patients may develop IBD-like lesions postoperatively. Nonetheless, we failed in identifying specific risk factors to be used to implement prevention strategies. Based on the results of our study, we suggest screening all TCSA patients with retrograde ileoscopy regardless of FC/OFB values. The frequency of endoscopic assessments and the role of FC/OFB screening in prompting endoscopy is yet to be determined.

Abstract
BACKGROUND Assessment of mucosal healing is important for the management of patients with inflammatory bowel disease (IBD), but endoscopy can miss microscopic disease areas that may relapse. Histological assessment is informative, but no single scoring system is widely adopted. We previously proposed an eight-item histological scheme for the easy, fast reporting of disease activity in the intestine. The aim of the present study was to evaluate the performance of our Simplified Histologic Mucosal Healing Scheme (SHMHS). METHODS Between April and May 2021 pathologists and gastroenterologists in Italy were invited to contribute to this multicenter study by providing data on single endoscopic-histological examinations for their IBD patients undergoing treatment. Disease activity was expressed using SHMHS (maximum score, 8) and either Simple Endoscopic Score for Crohn's Disease (categorized into grades 0-3) or Mayo Endoscopic Subscore (range 0-3). RESULTS Thirty hospitals provided data on 597 patients (291 Crohn's disease; 306 ulcerative colitis). The mean SHMHS score was 2.96 (SD = 2.42) and 66.8% of cases had active disease (score ≥ 2). The mean endoscopic score was 1.23 (SD = 1.05), with 67.8% having active disease (score ≥ 1). Histologic and endoscopic scores correlated (Spearman's ρ = 0.76), and scores for individual SHMHS items associated directly with endoscopic scores (chi-square p < 0.001, all comparisons). Between IBD types, scores for SHMHS items reflected differences in presentation, with cryptitis more common and erosions/ulcerations less common in Crohn's disease, and the distal colon more affected in ulcerative colitis. CONCLUSIONS SHMHS captures the main histological features of IBD. Routine adoption may simplify pathologist workload while ensuring accurate reporting for clinical decision making.

Abstract
Celiac Disease (CeD) is an immune-mediated inflammatory disorder of the small intestine, affecting genetically susceptible individuals when exposed to gluten. Small intestinal biopsy interpretation has been the “gold standard” for celiac disease (CeD) for over 50 years. Despite today’s availability of sensitive and specific serological tests, the histopathological features from mucosal biopsy play a key role in diagnosing when CeD is suspected. Such a diagnostic approach requires a multidisciplinary team to optimize both tissue sampling and interpretation via the interaction between the pathologist and the gastroenterologist. Pathologists of the Italian Group of Gastrointestinal Pathology (GIPAD-SIAPEC), together with a member (TR) of the Italian Society of Technicians (AITIC) and an expert gastroenterologist (CC), provide position statements as a practical tool for reading and interpreting the report. Moreover, a position statement was formulated about the recently described condition known as Non-Celiac Gluten Sensitivity (NCGS). Within such a diagnostic setting, both the architectural abnormalities of the duodenal mucosa, namely glandular hyperplasia, and villous atrophy and the number of intraepithelial T-lymphocytes should be well highlighted. Ancillary tests such as anti-CD3 stain are useful for an accurate count of the intraepithelial T lymphocytes when CeD or NCGS is suspected. Moreover, anti-CD3 and anti-CD8 stains are recommended in patients not responding to the gluten-free diet (GFD) to confirm a diagnosis of Refractory Celiac Disease (RCeD). Diagnostic clues about the differential diagnosis of both CeD and RCeD have also been rendered.

Abstract
BACKGROUND Crohn's disease (CD) and ulcerative colitis, two forms of inflammatory bowel disease (IBD), are chronic and relapsing conditions of the gastrointestinal tract both characterized by long lasting chronic inflammation and increased risk of dysplasia and colorectal cancer (CRC). The aim of our study was to evaluate the interobserver agreement about IBD-associated dysplasia among pathologists belonging to the Italian Group for Inflammatory Bowel Diseases (IG-IBD P). METHODS The present multicenter survey was performed using telepathology, supported by an open source E-learning platform. Biopsy specimens from 30 colonoscopies and from 20 patients were included. The glass slides of any case, including clinical and endoscopic data, were digitalized and uploaded on the E-learning platform. All the digital slides were grouped in 54 diagnostic "blocks". Blinded histopathological evaluation on all the digital slides was performed by 20 gastrointestinal pathologists. Closed-ended questions about (1) the occurrence of IBD; (2) the classification of IBD (as UC or CD); (3) the presence of active versus quiescent disease; (4) the presence of dysplasia; (5) the possible association of dysplasia with the sites of disease (dysplasia-associated lesion or mass-DALM vs adenoma-like mass-ALM); (6) the grading of dysplasia according to the ECCO guidelines (negative, indefinite, low grade, high grade categories) and (7) the presence of associated serrated features, were proposed in each case. Inter-observer agreement was evaluated by mean agreement percentage and kappa statistic, when suitable. RESULTS The diagnosis of IBD was confirmed in 19 of 20 patients, 17 of 19 being classified as UC, 2 as CD. The mean interobserver agreement percentages about (1) the evidence of IBD, (2) the presence of either UC or CD and (3) the activity grading resulted to be 80%, 69% and 86%, respectively. Dysplasia was detected in 8/20 patients, with moderate agreement between pathologists (mean 72%, k 0.48). Particularly, low grade dysplasia was found in 13 biopsies (combined k 0.38), whereas high grade dysplasia in 8 (combined k 0.47). When the endoscopic and histopathological data were combined, features consistent with DALM were found in 6 of 20 patients with low grade dysplasia and those consistent with ALM in 2 patients with low grade dysplasia in a single biopsy (mean agreement: 86%). An associated serrated pattern was discovered in 4 patients (7 biopsies). CONCLUSIONS Our study showed moderate interobserver agreement about the histopathological detection and classification of IBD-associated dysplasia. Further efforts should be undertaken to integrate the histopathological data with both the ancillary tests and molecular investigations.

Abstract
BACKGROUND There is substantial evidence linking disturbed gastrointestinal motility to inflammation. Thus, it is not surprising that abnormalities of gastrointestinal motility play a role in inflammatory bowel disease (IBD), affecting patient outcomes. We performed a review of the literature to investigate the relationship between abnormal gut motility and IBD. METHODS With an extensive literature search, we retrieved the pertinent articles linking disturbed gut motility to IBD in various anatomical districts. RESULTS The evidence in the literature suggests that abnormal gastrointestinal motility plays a role in the clinical setting of IBD and may confuse the clinical picture. CONCLUSIONS Abnormal gut motility may be important in the clinical setting of IBD. However, additional data obtained with modern techniques (e.g., magnetic resonance imaging) are needed to individuate in a more precise manner gastrointestinal motor dysfunctions, to understand the nature of clinical manifestations and properly tailor the treatment of patients.

Abstract
The Italian Society of Colorectal Surgery (SICCR) promoted the project reported here, which consists of a Position Statement of Italian colorectal surgeons to address the surgical aspects of inflammatory bowel disease management. Members of the society were invited to express their opinions on several items proposed by the writing committee, based on evidence available in the literature. The results are presented, focusing on relevant points. The present paper is not an alternative to available guidelines; rather, it offers a snapshot of the attitudes of SICCR surgeons about the general principles of surgical treatment of inflammatory bowel disease. The committee was able to identify some points of major disagreement and suggested strategies to improve quality of available data and acceptance of guidelines.

Abstract
BACKGROUND En bloc endoscopic submucosal dissection (ESD) has been recently introduced as a treatment for precancerous/neoplastic gastrointestinal conditions. The aim of the present study was histological assessment of en bloc ESD specimens. METHODS Fifty-three ESD specimens were positioned over a cellulose acetate support (40 specimens; 12 from the upper gastrointestinal tract and 28 from the lower gastrointestinal tract) or pinned with nails on polystyrene or cork (13 specimens; 7 from the upper gastrointestinal tract and 6 from the lower gastrointestinal tract). We cut consecutive 2 mm-thick sections stained with hematoxylin and eosin. From the first and the last sections, we obtained a second slide, after a 180° rotation and re-embedding. The quality of ESD samples was scored as inadequate, suboptimal and adequate, based on the amount of crushing, shearing and stretching artifacts that were scored from 0 (absent) to 2 (diffuse or maximum). From the sum of these we obtained a global artifact score (GAS). RESULTS Removed lesions were: adenocarcinoma (5 cases), neuroendocrine tumor (NET) G1 (1 case), premalignant conditions, including adenomatous polyps (41 cases) and hyperplastic lesions (6 cases). A positive deep surgical margin was found in 8/53 cases (15%): high- and low-grade dysplastic glands were detected in 5 cases, low-grade adenocarcinoma in 2, and NET cells in 1. Dysplastic glands were detected in the lateral surgical margins of 12 ESD specimens (23%). Among the ESD specimens positioned on the cellulose acetate support, apart from the modifications due to electrocoagulation, 2 (5%) showed shearing modifications. In the group of ESD specimens fixed with nails, 5 (38%) showed shearing, 10 (77%) crushing artifacts, 11 (85%) stretching and 11 (85%) multiple holes caused by the nails. On the basis of these data all histological specimens from ESD on cellulose acetate were adequate (GAS 0-1).However, in the group of ESD fixed with nails, 1 was adequate (GAS 0), 11 suboptimal (GAS 2-5) and 1 inadequate (GAS 6). CONCLUSIONS Specific devices including cellulose support and adequate sampling blocks can be helpful to perform accurate histological assessment of ESD specimens after en bloc ESD for precancerous/neoplastic gastrointestinal lesions, with complete analysis of the status of the margins and the entirely en bloc evaluation of the lesion.

Abstract
We examined 35 cases of stomach carcinoma and 40 cases of colonic carcinoma with PNA associated with peroxidase (peanut agglutinin, lectin which binds to the terminal disaccharide galactose β (1, 3)-N-acetil-galacto-samine). In this way evaluation of the functional aspects of the normal-neoplastic sequence was undertaken. This method was carried out for histological and ultrastructural investigations. The results obtained in both cases showed a different reactivity in the evolution of neoplastic disease: in fact, positivity in dysplasia is finely granular intracytoplasmic, whereas in well-differentiated neoplastic transformation such a reactivity is preferentially localized along the cellular membranes, with restoration of gross positivity in the cytoplasm for the poorly-differentiated neoplasm. We therefore believe PNA to be a marker not only of neoplastic progression but of differentiation as well: we also hypothesize it to reveal glycoprotein groups with possible antigenic power, involved in immunologic interactions between tumor and host.

Abstract
BACKGROUND AND PURPOSE The COX isoforms (COX-1, COX-2) regulate human gut motility, although their role under pathological conditions remains unclear. This study examines the effects of COX inhibitors on excitatory motility in colonic tissue from patients with diverticular disease (DD). EXPERIMENTAL APPROACH Longitudinal muscle preparations, from patients with DD or uncomplicated cancer (controls), were set up in organ baths and connected to isotonic transducers. Indomethacin (COX-1/COX-2 inhibitor), SC-560 (COX-1 inhibitor) or DFU (COX-2 inhibitor) were assayed on electrically evoked, neurogenic, cholinergic and tachykininergic contractions, or carbachol- and substance P (SP)-induced myogenic contractions. Distribution and expression of COX isoforms in the neuromuscular compartment were assessed by RT-PCR, Western blot and immunohistochemical analysis. KEY RESULTS In control preparations, neurogenic cholinergic contractions were enhanced by COX inhibitors, whereas tachykininergic responses were blunted. Carbachol-evoked contractions were increased by indomethacin or SC-560, but not DFU, whereas all inhibitors reduced SP-induced motor responses. In preparations from DD patients, COX inhibitors did not affect electrically evoked cholinergic contractions. Both indomethacin and DFU, but not SC-560, decreased tachykininergic responses. COX inhibitors did not modify carbachol-evoked motor responses, whereas they counteracted SP-induced contractions. COX-1 expression was decreased in myenteric neurons, whereas COX-2 was enhanced in glial cells and smooth muscle. CONCLUSIONS AND IMPLICATIONS In control colon, COX-1 and COX-2 down-regulate cholinergic motility, whereas both isoforms enhance tachykininergic motor activity. In the presence of DD, there is a loss of modulation by both COX isoforms on the cholinergic system, whereas COX-2 displays an enhanced facilitatory control on tachykininergic contractile activity.

Abstract
Celiac disease (CD) and inflammatory bowel disease (IBD), such as Crohn's disease (CrD) and ulcerative colitis (UC), are chronic inflammatory condition of the gastro-intestinal tract. The prevalence of IBD in celiac patients has been reported as 5-10 times higher than in the general population. The possibility of the presence of CD in IBD should be considered in IBD patients with long-term iron deficiency anemia (IDA) not responsive to iron supplementation. Non-celiac gluten sensitivity (NCGS) is characterized by intestinal and extra intestinal symptoms due to the ingestion of gluten-containing food in subject without CD and/or wheat allergy. Patients with Crohn's disease and SR-NCGS were more significantly affected by joint pains compared to UC patients (50% versus 11.1%). In Crohn's patients, a higher percentage of fatigue (50% versus 38.9%) and headache (27.3% versus 22.2%) was evident. For the association between NCGS and IBD new studies are warranted and, at this moment, a gluten free diet (GFD) may be useful more in CrD than in UC.

Abstract
Senescence is accompanied by various anatomical and functional alterations starting from mastication and deglutition and consequent modifications of nutrition. In addition, the widespread use of proton pump inhibitors and non-steroidal anti-inflammatory drugs in aged subjects weakens the gastric barrier, thus contributing to easier entry of microbes into the gastrointestinal tract. The microbiota of the elderly is less stable than that of younger adults, therefore, gut dysbiosis is more frequent. Dysbiosis represents a key factor for infections, e.g. Clostridium difficile, especially after antibiotic treatment, but also represents an important step for the development of inflammatory bowel diseases (IBD). IBD onset in the elderly needs careful evaluation in order to distinguish this entity from other pathologies that may affect the gut in senescence. Colitis associated with diverticula, drug-induced, ischemic, and microscopic colitides are among the possible diseases and, therefore, a careful macroscopic and histologic evaluation is mandatory. Finally, late onset IBD represents an important challenge for physicians since it occurs in subjects with frequent comorbidities and relative concomitant treatments. Although there is some evidence that disease course of elderly-onset IBD follows a milder course, overall morbidity, hospitalization rates and even mortality, the latter mostly due to comorbidities, are increased, especially in emergency settings.

Abstract
BACKGROUND It is unknown whether symptoms in non-coeliac patients (non-CD) meeting clinical diagnostic criteria for noncoeliac gluten sensitivity (NCGS) are specifically triggered by gluten. AIM To assess gluten sensitivity in patients diagnosed with NCGS. METHODS We studied 35 non-CD subjects (31 females) that were on a gluten-free diet (GFD), in a double-blind challenge study. Participants were randomised to receive either gluten-containing flour or gluten-free flour for 10 days, followed by a 2-week washout period and were then crossed over. The main outcome measure was their ability to identify which flour contained gluten. Secondary outcome measures were based upon Gastrointestinal Symptoms Rating Scale (GSRS) scores. RESULTS The gluten-containing flour was correctly identified by 12 participants (34%), who were classified as having NCGS. Their mean GSRS dimension scores were significantly higher following gluten challenge compared to baseline. The scores were: pain, 1.7 ± 0.8 vs. 2.6 ± 1.0; reflux, 1.6 ± 0.5 vs. 2.2 ± 0.9; indigestion, 1.9 ± 0.7 vs. 3.2 ± 1.1; diarrhoea, 1.6 ± 0.7 vs. 2.9 ± 1.5 and constipation, 1.9 ± 0.9 vs. 2.9 ± 1.3. Seventeen participants (49%) erroneously considered the gluten-free flour to contain gluten. Their mean GSRS dimension scores were significantly higher following gluten-free flour challenge compared to baseline. The scores were: pain, 1.6 ± 0.9 vs. 3.0 ± 0.9; reflux, 1.4 ± 0.5 vs. 2.3 ± 1.1; indigestion, 2.0 ± 1.1 vs. 3.7 ± 1.1; diarrhoea, 1.6 ± 0.7 vs. 3.0 ± 1.2 and constipation, 1.6 ± 0.9 vs. 2.6 ± 1.3. The other six participants (17%) were unable to distinguish between the flours. CONCLUSION Double-blind gluten challenge induces symptom recurrence in just one-third of patients fulfilling the clinical diagnostic criteria for non-coeliac gluten sensitivity.

Abstract
The histologic examination of endoscopic biopsies or resection specimens remains a key step in the work-up of affected inflammatory bowel disease (IBD) patients and can be used for diagnosis and differential diagnosis, particularly in the differentiation of UC from CD and other non-IBD related colitides. The introduction of new treatment strategies in inflammatory bowel disease (IBD) interfering with the patients' immune system may result in mucosal healing, making the pathologists aware of the impact of treatment upon diagnostic features. The European Crohn's and Colitis Organisation (ECCO) and the European Society of Pathology (ESP) jointly elaborated a consensus to establish standards for histopathology diagnosis in IBD. The consensus endeavors to address: (i) procedures required for a proper diagnosis, (ii) features which can be used for the analysis of endoscopic biopsies, (iii) features which can be used for the analysis of surgical samples, (iv) criteria for diagnosis and differential diagnosis, and (v) special situations including those inherent to therapy. Questions that were addressed include: how many features should be present for a firm diagnosis? What is the role of histology in patient management, including search for dysplasia? Which features if any, can be used for assessment of disease activity? The statements and general recommendations of this consensus are based on the highest level of evidence available, but significant gaps remain in certain areas.

Abstract
BACKGROUND Alterations of small intestinal transit and gallbladder (GB) motility have been reported in celiac disease (CD) in studies involving, in most cases, non-physiological experimental conditions and artificial stimuli to motility. Our aims were to quantitate non-invasively small intestinal transit time and GB emptying during administration of a physiological and palatable solid meal, and to assess the effect of gluten-free diet (GFD). METHODS We simultaneously measured mouth-to-cecum transit time (MCTT) using a validated H(2) breath test, and GB motility using ultrasonography. We studied CD patients before (n = 19) and during (n = 14) GFD, and healthy volunteers (n = 24) following administration of a physiological solid meal (Kcal 539). KEY RESULTS Mouth-to-cecum transit time was more prolonged in CD (mean ± SEM: 235 ± 96 min) than in controls (169 ± 65 min, P = 0.0039). The GB fasting volume and postprandial residual volume were significantly higher in CD than in controls, and GB emptying constant was slower in CD than in controls. During GFD, GB emptying reverted to normal, but MCTT remained unchanged (229 ± 69 min) and more prolonged in CD than in controls (P = 0.0139). During GFD, duodenal infiltration with lymphocytes and mast cells persisted higher than that in controls, and the number of mast cells lying in proximity of nervous endings did not change. CONCLUSIONS & INFERENCES Slow postprandial MCTT in response to a physiological meal does not revert to normal during GFD, an effect mirroring incomplete histopathologic recovery.

Abstract
BACKGROUND AND AIMS Our study evaluated the prevalence, the characteristics and implications of the upper gastrointestinal localisation (UGI+) in paediatric Crohn's Disease (CD) patients. METHODS This prospective study evaluated 45 newly diagnosed CD patients at diagnosis and follow up with respect to CD localisation. RESULTS All patients presented CD at the colon and/or ileum. In 24/45 patients (53.3%, 12 F and 12 M) an UGI+ involvement was also found. UGI+ patients had a younger age of onset (10.9 years versus 12.6 years; P<0.05). PCDAI at diagnosis was significantly higher in the UGI+ (41 vs. 25 P<0.01). UGI+ patients were overall more symptomatic. Pancolitis and extraintestinal manifestations were also more frequent (19/24 (80%) vs. 12/21 (57%) P<0.01). Growth was more impaired at diagnosis in UGI+ patients. By the end of the follow-up (mean 3 years, range 2 to 4) no significant difference was found in PCDAI (17 in UGI+ patients vs. 11 in UGI- P=NS), or the number of relapses. Weight and growth catch-up in UGI+ patients were comparable to UGI- ones. However, UGI+ patients required a more aggressive therapeutic approach. CONCLUSION At least half of paediatric onset CD patients have an upper gastrointestinal localisation. UGI+ patients present an earlier onset and a more severe disease. The final outcome does not differ, but UGI+ patients require a more aggressive therapeutic approach.

Abstract
Functional chronic constipation is a common symptom in daily clinical practice. Although the definition of constipation may be variable, there is usually agreement that (at least for research purposes) the definition given by the Rome Committee are useful. However, some blind spots or hidden angles remain, even in the more thorough classifications; among these, there is painful constipation, a poorly defined yet clinically encountered entity. The present article reviews the current knowledge about painful constipation, trying to put together the scarce data available, and to frame it in the more general context of chronic constipation.

Abstract
BACKGROUND There is recent evidence that mast cells may play important roles in the gut, especially concerning visceral hypersensitivity and motor activity. However, most data are only available for clinical conditions characterised by diarrhoea, where MC have chiefly investigated in the mucosal layer of the colon and there is almost no information concerning constipation. AIM To investigate mast cells distribution in all colonic layers in controls and severely constipated patients. METHODS Full-thickness specimens from colons of patients undergoing surgery for slow transit constipation (n=29), compared with controls, were obtained and the number of mast cells (evaluated by specific monoclonal antibodies) counted as a whole and in single colonic segments (caecum, ascending, transverse, descending and sigmoid). RESULTS Compared with controls, constipated patients revealed significantly higher number of mast cells, both as overall number and in single colonic segments. The distribution of mast cells resulted fairly homogeneous in the various segment of the large bowel, in both controls and patients, and no significant difference in the percentage of degranulated cells was found between groups. CONCLUSIONS Colonic mast cells display a homogeneous distribution within the viscus. This cell population is shown to increase in severely constipated patients, which might represent a mechanism trying to compensate for the impaired propulsive activity of these patients.

Abstract
BACKGROUND Accuracy of intraepithelial lymphocytes counts for diagnosing mild enteropathy coeliac disease in absence of villous atrophy can be limited by inappropriate controls included in the studies. AIM To determine the diagnostic accuracy of intraepithelial lymphocytes counts utilising controls lacking HLA coeliac disease-associated alleles. METHODS Intraepithelial lymphocytes counting at villus tip and per 100 enterocytes was performed at haematoxylin and eosin (H&E) and CD3-stainings in: 29 cases (21 with potential coeliac disease and 8 affected by latent coeliac disease) representing the patient population and 14 noncoeliac controls lacking HLA-DQ2/DQ8 alleles. RESULTS Threshold (mean+2 s.d.) of duodenal intraepithelial lymphocytes at villus tip and per 100 enterocytes in noncoeliac controls was respectively: 3.5 and 18 at H&E, 3.2 and 17 following CD3-staining. Considering the whole patient population, the sensitivity of tip intraepithelial lymphocytes in detecting mild enteropathy coeliac disease was 90% (95% CI=72.6-97.8) both at H&E and CD3-stainings. The sensitivity of intraepithelial lymphocytes per 100 enterocytes was 93% (95% CI=77.2-99.2) both at H&E and CD3-staining. Specificity of both intraepithelial lymphocytes counts was 100% (95% CI=76.8-100). Using a threshold of 25 intraepithelial lymphocytes per 100 enterocytes could miss 59% of cases at H&E and 48% following CD3-staining. CONCLUSIONS Intraepithelial lymphocytes counts are diagnostic feasible tools to detect mild enteropathy coeliac disease. Threshold of duodenal intraepithelial lymphocytes may be lower than currently accepted.

Abstract
BACKGROUND to date, there are few data on colonoscopic findings in patients with celiac disease, and most of these obtained in patients with iron deficiency anaemia. AIMS we assessed colonoscopic findings in unselected patients with coeliac disease, since there are no studies available also considering morphological aspects, and there is literature suggestion of increased prevalence of colorectal tumours. MATERIAL AND METHODS colonoscopies with multiple biopsies were retrospectively analyzed in 42 coeliac disease patients on gluten-free diet above age 40; 16 had clinical or laboratory features of iron deficiency anaemia. Mucosal biopsies were evaluated for the presence of intraepithelial lymphocytes and of mucosal eosinophils, in addition to conventional histologic assessment, and compared with those obtained in 15 controls. RESULTS macroscopic abnormalities (polyps, diverticula, inflammatory changes) were found in 26% of patients. Microscopic abnormalities (lymphocytic colitis, melanosis coli, rectal histiocytosis) were found in 36% of patients. None of these findings was found in controls. Coeliac disease patients had significantly higher eosinophil score than controls in the right colon, whereas this was not significantly different between groups in the left colon. CONCLUSIONS colonoscopic findings in coeliac disease on gluten-free diet may reveal significant findings, even in patients without iron deficiency anaemia. There is the need of further studies in larger cohorts of patients to establish whether colonoscopy in these patients may be clinically useful.

Abstract
Until a few years ago, celiac disease (CD) was thought to be a rare food intolerance that was confined to childhood and characterized by severe malabsorption and flat intestinal mucosa. Currently, CD is regarded as an autoimmune disorder that is common in the general population (affecting 1 in 100 individuals), with possible onset at any age and with many possible presentations. The identification of CD is challenging because it can begin not only with diarrhea and weight loss but also with atypical gastrointestinal (constipation and recurrent abdominal pain) and extra-intestinal symptoms (anemia, raised transaminases, osteoporosis, recurrent miscarriages, aphthous stomatitis and associated autoimmune disorders), or it could be completely symptomless. Over the last 20 years, the diagnostic accuracy of serology for CD has progressively increased with the development of highly reliable tests, such as the detection of IgA tissue transglutaminase and antiendomysial and IgG antideamidated gliadin peptide antibodies. The routine use of antibody markers has allowed researchers to discover a very high number of 'borderline' cases, characterized by positive serology and mild intestinal lesions or normal small intestine architecture, which can be classified as potential CD. Therefore, it is evident that the 'old celiac disease' with flat mucosa is only a part of the spectrum of CD. It is possible that serology could identify CD in its early stages, before the appearance of severe intestinal damage. In cases with a positive serology but with mild or absent intestinal lesions, the detection of HLA-DQ2 and HLA-DQ8 can help reinforce or exclude the diagnosis of gluten sensitivity.

Abstract
AIM The diagnosis of celiac disease (CD) is still mainly based on pathological description. However, these descriptions are often unable to identify latent CD. The aim of this study was to evaluate whether the Marsh-Oberhuber classification and a recently proposed classification may help to identify patients with latent CD. METHODS Biopsy samples from twelve patients with latent CD (age range 3-32 years) defined as having normal duodenal mucosa when ingesting a free diet, and subsequently developing severe villous atrophy, were retrospectively reviewed in blind according to the Marsh-Oberhuber classification and the new grading system. RESULTS In 67% of patients the Marsh-Oberhuber and the new classification could have yielded a diagnosis of CD soon after the first biopsy (3a-3c score when reviewed according to this classification, and B2 score when reviewed according to the new grading system), thereby avoiding further (up to two more in four cases) unnecessary endoscopic procedures. CONCLUSION Both the Marsh-Oberhuber and the new classification allow to discriminate latent CD from patients with normal mucosa. Thus, these classifications may help in identifying and treating patients at an early stage.

Abstract
BACKGROUND we assessed the prevalence, the related symptoms, and the endoscopic and histologic gastric features of celiac disease (CD) in patients with Helicobacter pylori (Hp). METHODS 450 dyspeptic patients were studied. Biopsies of gastric antrum and duodenum, CD serology, and total IgA were obtained. Histological findings were scored with the Marsh-Rostami criteria. RESULTS 411 (91.3%) patients were Hp positive. Duodenal histology was normal in 385 (85.6%) patients, 124 (27.5%) had duodenitis and 28 (6.2%) showed duodenal abnormalities (Marsh I-IIIc). Twenty three/28 (82.1%) patients with malabsorption pattern were also Hp positive. Serological analysis: 12 of 31 (38.7%) positive patients had abnormal histology (Marsh I,-IIIc). Nine out 450 patients were IgA deficient; none of them was serologically positive for CD. CONCLUSION although a high prevalence of Hp infection was found in this study, the relationship between Hp infection and CD was similar to that reported in other geographic areas.

Abstract
BACKGROUND Eosinophilic esophagitis is an esophageal disorder characterized by esophageal and/or upper gastrointestinal tract symptoms, and by dense esophageal eosinophilia associated with a normal gastric and duodenal mucosa. Prevalently reported in children, eosinophilic esophagitis has recently been reported with increased frequency also in adults. AIMS The purpose of this study was to report our experience with eosinophilic esophagitis in Italy, since there are only very few series of such patients in our country. PATIENTS AND METHODS We retrospectively reviewed the histological data of consecutive patients with a diagnosis of esophagitis or reflux disease in the period September 2004-September 2008. Eosinophils were counted where they appeared most numerous in the biopsy, with a cutoff > 15 eosinophils in more than one high-power field as diagnostic of eosinophilic esophagitis. Patients were excluded if gastric or duodenal biopsies showed a prominent eosinophilic infiltrate. RESULTS Twenty two patients (14 adults, 8 children, age range 2-59 years) were identified according to the above criteria. The average eosinophil count was 86/ high-power field (range 31-150), associated with other pathologic features (eosinophilic microabscesses eosinophil degranulation, basal zone hyperplasia, papillary elongation). The main clinical complaints were dysphagia, food impaction, and heartburn, and endoscopic findings consisted of mucosal thickening and inelasticity, longitudinal shearing, rings, and white specks, without difference between adults and children for both clinical and endoscopic variables. CONCLUSIONS Eosinophilic esophagitis is not rare in Italy, and displays clinical, endoscopic, and pathologic features similar to those described in other countries.

Abstract
BACKGROUND Expected benefits of gluten-free diet (GFD) in coeliac patients include healing of small intestinal mucosa, but it remains unclear to what extent this benefit is achieved in adults. AIM To assess factors affecting histological outcome of GFD in a large cohort of adult coeliac patients. METHODS We extracted information on 465 consecutive coeliac patients studied before and during GFD. RESULTS Duodenal biopsies at diagnosis were classified as Marsh I in 11, II in 25 and III in 429 cases. After a median 16 months GFD, 38 (8%) patients had histological 'normalization', 300 (65%) had 'remission' with persistent intraepithelial lymphocytosis, 121(26%) had 'no change' and 6 (1%) had 'deterioration'. Coeliac disease related serology was negative in 83% of patients with Marsh III lesion during GFD. Male gender and adherence to GFD were independently associated with histological 'normalization' and 'remission'. Persistence of intraepithelial lymphocytosis was not associated with human lymphocyte antigen gene dose or with Helicobacter pylori infection. CONCLUSIONS Complete normalization of duodenal lesions is exceptionally rare in adult coeliac patients despite adherence to GFD, symptoms disappearance and negative CD related serology. Control biopsies are mandatory to identify lack of response to gluten-free diet.

Abstract
Abstract
Background
Interactions between the colonic lymphoid system and the genetic background in Crohn's disease are unexplored. This study analysed variations of colonic lymphoid follicles (CLFs) according to the nucleotide-binding oligomerization domain 2 (NOD2) and caspase recruitment domain-containing protein 15 (CARD15) gene in patients with Crohn's disease.
Methods
CLFs were characterized by histology and immunohistochemistry in the specimens of 41 patients undergoing colonic resection for Crohn's disease. Variants of the NOD2/CARD15 gene were assessed by denaturing high performance liquid chromatography and confirmed by DNA sequencing.
Results
Eleven patients had a heterozygous variant of the NOD2/CARD15 gene. The uninvolved colon of mutants had significantly lower CLF density (0·9 versus 2·7 follicles per cm2; P < 0·001) and proportion of those with a germinal centre (9 versus 22 per cent; P = 0·040) than in non-mutants. In active disease, CLF density increased similarly in patients with and without the mutation. The proportion of extramucosal CLFs was higher in mutants than in non-mutants (34 versus 22 per cent; P = 0·030). No significant difference between groups was recorded for cellular profile and proliferation.
Conclusion
Patients with Crohn's disease and the NOD2/CARD15 mutation show a remodelling of CLFs in both uninvolved and actively inflamed intestines. These subjects may have a defective immune response by organized lymphoid structures.

Abstract
The diagnosis of coeliac disease has traditionally depended on symptoms and intestinal biopsies; nowadays, the diagnosis has been expanded to include an array of serological markers and subtle microscopic lesions. The most important advance in classifying mucosal lesions in coeliac disease was forwarded by Marsh (1992), who provided the biological explanation of how the small bowel reacts to a variety of environmental antigenic challenges including gluten. In the modified version of this classification (Arnhem 1998-1999) autoantibodies have integrated into Marsh's histopathological scheme. As a large part of the coeliac 'iceberg' remains unrecognised, the difficulties in diagnosis continue to challenge clinicians and researchers. Advances in immuno-histochemistry and discovery of the other sensitive markers have acquainted us with so-called Microscopic enteritis, the distinctive subtle abnormalities behind the atypical gluten sensitivity symptoms that often remain unrecognised. Current diagnostic pathways do not always include facilities for looking for this common histological feature in atypical cases. This is essential since improving of the detection rate has been shown to be directly proportional to recognition of cases with milder or minimal mucosal abnormalities. In this revision, we will define and characterise microscopic enteritis as the entity behind a wide range of unexplained gastrointestinal symptoms. Screening for this subtle and distinctive presentation in small bowel pathology will open a new prospect in recognising the most common but unrecognised atypical forms of symptomatic gluten related enteropathies.

Abstract
BACKGROUND The colon shows frequent eosinophilic infiltration in allergic proctocolitis of infants, whereas in adults, eosinophilic infiltration of the colon is less defined and may be found in different conditions including drug-induced colitis, even though the pathological findings are often inconsistent. AIM To quantify eosinophils in the mucosa of normal controls and to compare them with those of patients with abdominal symptoms related to 'drug colitis'. METHODS Mucosal biopsies were obtained during colonoscopy in 15 controls and in 27 patients with abdominal symptoms, a history of probable 'drug-related colitis' and without obvious causes of eosinophilia. RESULTS The drugs related to the patient symptoms were nonsteroidal anti-inflammatory drugs (70%), antiplatelet agents (19%) and oestroprogestinic agents (11%). Colonoscopy was normal in 30% of patients and abnormal in 70%. Histology showed low content of inflammatory cells and normal crypt architecture in-patients with endoscopy similar to inflammatory bowel diseases. The eosinophil score was significantly higher in the left side of the colon in the patient group compared with controls. CONCLUSIONS The finding of an increased eosinophil count limited to the left (descending and sigmoid) colon is an important clue towards a diagnosis of drug-related colitis.

Abstract
AIM Human epidermal growth factor receptor (HER2) protooncogene, overexpressed/ amplified in preneoplastic lesions and in adenocarcinoma (ADC) of the esophagus, can be considered a target for treatment of esophageal dysplasia/ADC. The aim of this study was to evaluate the therapeutic role of the anti-HER2 monoclonal antibody, trastuzumab, in the management of ADC originating from HER2-positive Barrett's esophagus (BE). METHODS Two patients with high-grade dysplasia and ADC of the esophagus after esophageal mucosectomy and no metastatic disease were studied. Patients were not eligible for radical surgery or chemo-radiotherapy because of age and comorbidities. HER2 status was assessed by immunohistochemistry and fluorescence in situ hybridization. Additional immunohistochemical analyses were performed. The whole panel was analysed at baseline, after treatment and at follow-up. RESULTS At baseline, the two patients showed HER-2 overexpression/amplification in all areas of dysplasia and ADC but not in BE. Six months after treatment no significant differences in terms of endoscopical and histological patterns of the disease were found. HER-2, EGFR, TOPOII-alpha and anti-ssDNA analysis demonstrated a down-regulation of these markers and increased apoptosis. CONCLUSION This study demonstrates that this treatment is feasible. No clear evidence of dysplasia regression was observed. However, HER2 and TopoII-alpha downregulation and induction of apoptosis occurring 6 months after treatment encourages further investigation.

Abstract
Various studies have described abnormalities of the enteric nervous system (ENS) in tissue samples from patients with chronic idiopathic inflammatory bowel diseases (IBD). The distribution of density of the different cell types of the ENS was however not studied in a systematic way. The aim of this study was to examine the density of neurons, enteroglial cells and interstitial cells of Cajal (ICC) in the different plexuses of the ENS in samples from patients with Crohn's disease (CD), ulcerative colitis (UC) and controls. Tissue samples from 16 patients with CD (ileum) and 16 patients with UC obtained in involved and non-involved areas were studied using immunohistochemistry with antibodies directed against neuron-specific enolase, S100, C-Kit and CD3. Sections were analysed blindly by two pathologists and the number of positive cells was counted for each type. Overall, an increase was noted for neuronal cell bodies, enteroglia and ICC in the deep muscular plexus in CD. In uninvolved areas of CD patients, the number of enteroglial cells was decreased. In UC, an increase of ICC in the muscularis propria and enteroglial cells was observed in diseased tissue. The study confirms the presence of abnormalities of the different cells of the ENS in IBD. The presence of lesions in samples from uninvolved areas, such as a reduction of enteroglia, supports a pathogenetic role of the ENS.

Abstract
Confocal laser endomicroscopy (CLE) was carried out in seven patients with chronic watery diarrhea (three men; age range 68 - 84 years) to find the correspondence between CLE and histological findings in collagenous colitis. On the basis of the CLE images, two to five biopsies were performed in various segments of the colon. The endoscopic and histological diagnoses of collagenous colitis were made blindly. The quality of the CLE images was quantified from 0 (the endoscopist could not visualize the corresponding histologic equivalent) to 3 (the endoscopist could identify >or= 80 % of the corresponding histologic equivalent). Four out of seven patients had histological findings of collagenous colitis. Correspondence between histology and CLE images yielded the following scores: 3 for epithelial architecture, 3 for goblet cells, 3 for vessels, and 2 for inflammatory infiltrate. In collagenous colitis patients, CLE identified a well-defined "shell" around the crypts, corresponding to the increase in the thickness of the subepithelial collagenous plate evidenced by histology. CLE appears to be a promising means of identifying typical collagenous colitis features.

Abstract
The adaptor protein Rai (ShcC/N-Shc) is almost exclusively present in the nervous system, although little is documented about its expression in the gut and the enteric nervous system (ENS). As Rai is a physiological substrate of Ret, an important factor for the development of ENS, we have evaluated the expression of Rai in the ENS in various segments of the human gastrointestinal tract. The expression of Rai was assessed by immunohistochemistry in disease-free human gut samples (oesophagus, stomach, small bowel and colon) obtained from subjects undergoing surgical procedures. Rai was not expressed in the epithelia or lymphoid tissue, whereas a moderate level of expression was observed in the endothelial cells of blood vessels and on the outer membrane of smooth muscle cells in both the muscularis mucosae and the muscularis propria. In the ENS, strong positivity was observed only in enteric glial cells, overlapping with GFAP and S100. In conclusion, Rai is expressed in the human gut, especially in the enteric glial cells. We conclude that Rai may provide an additional marker for this cell type.

Abstract
Duodenal confocal laser endomicroscopy (CLE) was carried out in six patients to compare the findings with histology. The visibility and quality of the endomicroscopy images were quantified using the following score: 0 = none; 1 = poor; 2 = fair; 3 = good. Four patients had a normal duodenal mucosa, whereas two patients in whom CLE indicated villous atrophy showed histologic features typical of celiac disease. Histology and CLE images were similar in both normal and celiac disease patients; patients with celiac disease had an average score of 3 for epithelial architecture, 3 for goblet cells, 3 for vessels, 1 for inflammatory infiltrate, and 2 for crypt visibility.

Abstract
OBJECTIVE It is not common that, after diversion of the faecal stream by a colostomy, the defunctioned colon develops colitis. The pathogenesis of this colitis is still unclear and it has been proposed that ischaemia may play a major role. Our aim is to look for signs of ischaemia in a group of patients developing colitis after diversion colostomy for various causes. METHOD Surgical specimens from 32 patients resected for colitis developed after diverting colostomy were examined with routine (haematoxylin-eosin) and Elastic-Van Gieson and Perls' stains. RESULTS The histological features related to mucosal crypt architecture, crypt epithelium and inflammation were mild, non specific or related to the underlying disease. Fibrosis was present in 21 (65.6%) patients, superficial coagulative necrosis was found in 18 (56%) patients, splitting and/or thickening of muscularis mucosae was present in 20 (62%) patients. The vessels were substantially normal or ectasic without thrombi or alterations in the wall. Evident ischaemia with coagulative necrosis, submucosal oedema and focal fibrosis was detected in only two (6%) patients and an intermediate picture between acute and chronic ischaemia was present in 16 (50%) patients. CONCLUSION It is possible that ischaemia plays some role in the pathogenesis of diversion colitis; however, further studies are needed to firmly establish its role.

Abstract
The pathogenesis of slow transit constipation is still elusive. However, a genetic basis may be present. We investigated possible chromosomal abnormalities in enteric neurons and glial cells in patients with slow transit constipation. Colonic specimens from 22 patients with slow transit constipation undergoing surgery for intractable symptoms were obtained, and investigated by fluorescence in situ hybridization (FISH) for chromosomal abnormalities (chromosomes 1, 8, 17 and XY). These specimens were compared with of those obtained in 12 control subjects. Data analysis showed that 45.5% of patients displayed significant (>10%) aneusomy of chromosome 1 in enteric neurons. Aneusomy <10% for the same chromosome, but less than the cutoff suggested (10%), was found in enteric glial cells in 45.4% of the same patients. One patient had <10% aneusomy in enteric neurons for chromosome 8. No other abnormalities were found for the remaining probes, and no abnormalities were found in controls. We concluded that in a subgroup of patients with slow transit constipation a genetic basis may be present.

Abstract
AIMS To assess the histological response to a gluten-free diet (GFD) in a series of coeliac patients in clinical remission, of different ages and with varying degrees of mucosal damage at diagnosis. METHODS AND RESULTS Biopsy samples from 249 coeliac patients (F 165, M 84) were analysed basally and after clinical and biochemical remission following a GFD. All patients showed an improvement in mucosal findings after starting a GFD, but complete histological normalization was observed in 74.1% of paediatric cases (diagnosed before 14 years of age) and in only 17.5% of adults. Statistical analysis showed that sex, the clinical picture at diagnosis and the length of time between biopsy at the time of diagnosis and on a GFD were not related to histological normalization. In contrast, the age at diagnosis was statistically significantly related to it (P < 0.0001). In addition, the presence/absence of Helicobacter pylori was independent of the normalization of the duodenal mucosa. CONCLUSIONS In clinical practice the criteria for diagnosis of coeliac disease are sufficiently standardized, whereas for follow-up they are less well defined. We suggest that in order to compare the results from different studies, it should be stated whether remission after treatment is based on clinical or histological criteria or both.

Abstract
BACKGROUND Immunohistochemical changes associated with development of cancer in Barrett's esophagus offer potential areas of intervention to prevent and manage esophageal cancer. AIMS To assess the role of cyclooxygenase 2, caudal-type homeobox transcription factor 2 and cell division cycle 2/cyclin-dependent kinase 1 in the Barrett's metaplasia-dysplasia-adenocarcinoma sequence. PATIENTS AND METHODS Specimens from 46 patients with Barrett's esophagus (39% without dysplasia, 33% with dysplasia and 28% with adenocarcinoma) were stained for cyclooxygenase 2, caudal-type homeobox transcription factor 2 and cell division cycle 2. RESULTS Cyclooxygenase 2: No expression differences between groups were found, except for adenocarcinomas (p=0.04). Caudal-type homeobox transcription factor 2: Nuclear positivity decreased from Barrett's esophagus without dysplasia (71.6%), to Barrett's esophagus with low grade dysplasia (35.3%), to Barrett's esophagus with high grade dysplasia (17.14%); in adenocarcinoma these percentages were intermediate between high and low grade dysplasia (30.5%). Cell division cycle 2: Expression on deeper glandular structures was 40% in Barrett's esophagus without dysplasia, 55.47% in Barrett's esophagus with dysplasia, and 63.84% in adenocarcinoma, with no statistical differences between groups. Concerning cells of the superficial layer, Barrett's esophagus with low grade dysplasia expressed focal positivity (p=0.0001 vs. no dysplasia); Barrett's esophagus with high grade dysplasia displayed diffuse positivity (p=0.0001 vs. no dysplasia and low grade dysplasia). A diffuse positivity was found in Barrett's esophagus with adenocarcinoma (p=0.0001 vs. no dysplasia and low grade dysplasia). CONCLUSIONS Further evaluation of cyclooxygenase 2, cell division cycle 2 and caudal-type homeobox transcription factor 2, in association with morphology, might help to improve the accuracy of diagnosis and be useful for the clinical-pathological assessment of patients with Barrett's esophagus.

Abstract
Barrett's esophagus (BE) is a complication of chronic gastroesophageal reflux disease (GERD) and is the precursor of esophageal adenocarcinoma (EA), through a progression from intestinal metaplasia (IM), through high-grade dysplasia (HGD). Although the progression from BE to EA seems to be infrequent (0.5% per year), endoscopic and bioptic surveillance would play a significant role in the evaluation of HGD and the detection of EA in early, curable stage, improving survival rates after treatments. The severity and the duration of GERD could be helpful in the assessment of the risk for BE and to enroll these subjects into screening protocols to detect any dysplastic or neoplastic change. The benefits of screening-surveillance programs could be furthermore enhanced by an improvement in diagnostic methods, such as high-resolution endoscopic techniques and the use of biomarkers for the histological examination seems to play a primary role in the cancer risk stratification; in such way, endoscopic resection techniques (mucosal resection and submucosal dissection) can be considered as a helpful method to stage dysplastic changes in BE.

Abstract
AIMS To study relationships between the number of pseudomelanosis coli cells and that of colonic enteric neurons and interstitial cells of Cajal, which are significantly reduced compared with controls in severely constipated patients. Pseudomelanosis coli is frequent in patients using anthraquinone laxatives. It is not known whether the prolonged use of these compounds damages the enteric nervous system in constipated patients. PATIENTS AND METHODS The relationship between the number of pseudomelanosis coli cells and that of colonic enteric neurons (as well as that of apoptotic enteric neurons) and of interstitial cells of Cajal was assessed by histological and immunohistochemical methods in 16 patients with chronic use of anthraquinone laxatives undergoing surgery for severe constipation unresponsive to medical treatment. No relationship was found between the number of pseudomelanosis coli cells and that of enteric neurons (and that of the apoptotic ones), nor of interstitial cells of Cajal, in either the submucosal or the myenteric plexus. CONCLUSION The use of anthraquinone laxatives, leading to the appearance of pseudomelanosis coli, is probably not related to the abnormalities of the enteric nervous system found in severely constipated patients.
