Abstract
BACKGROUND Celiac disease (CD) is associated with an increased risk for lymphoproliferative malignancy (LPM). Whether this risk is affected by the results of follow-up intestinal biopsy, performed to document mucosal healing, is unknown. OBJECTIVE To examine the association between mucosal healing in CD and subsequent LPM. DESIGN Population-based cohort study. SETTING 28 pathology departments in Sweden. PATIENTS 7625 patients with CD who had follow-up biopsy after initial diagnosis. MEASUREMENTS The risk for LPM was compared with that of the general population by using expected rates. The rate of LPM in patients with persistent villous atrophy was compared with that of those with mucosal healing by using Cox regression. RESULTS Among 7625 patients with CD and follow-up biopsy, 3308 (43%) had persistent villous atrophy. The overall risk for LPM was higher than that in the general population (standardized incidence ratio [SIR], 2.81 [95% CI, 2.10 to 3.67]) and was greater among patients with persistent villous atrophy (SIR, 3.78 [CI, 2.71 to 5.12]) than among those with mucosal healing (SIR, 1.50 [CI, 0.77 to 2.62]). Persistent villous atrophy compared with mucosal healing was associated with an increased risk for LPM (hazard ratio [HR], 2.26 [CI, 1.18 to 4.34]). The risk for T-cell lymphoma was increased (HR, 3.51 [CI, 0.75 to 16.34]) but not for B-cell lymphoma (HR, 0.97 [CI, 0.21 to 4.49]). LIMITATION No data on dietary adherence. CONCLUSION Increased risk for LPM in CD is associated with the follow-up biopsy results, with a higher risk among patients with persistent villous atrophy. Follow-up biopsy may effectively stratify patients with CD by risk for subsequent LPM.

Abstract
BACKGROUND Classification of refractory celiac disease (RCD) is based on the presence or absence of monoclonal expansions of intraepithelial lymphocytes (IELs) with an aberrant immunophenotype. GOALS To investigate the contribution of IEL parameters toward mortality and morbidity in RCD. STUDY IEL phenotype by immunohistochemistry and T-cell receptor (TCR) gene rearrangement by polymerase chain reaction were assessed in 73 RCD patients (type I=67, type II=6). Detection of a monoclonal TCR gene rearrangement and presence of <50% CD3 CD8 IELs were considered abnormal. Time to worsening of clinical symptoms and predictors of worsening were calculated by Kaplan-Meier and Cox proportional hazard analyses. RESULTS Fewer than 50% CD3 CD8 IELs were detected in 30 patients and monoclonal TCR rearrangements in 6. Three patients died and 40 suffered clinical worsening despite treatment. Estimated 5-year survival rates decreased from 100% in patients with >50% CD3 CD8 IELs and polyclonal TCR to 88% and 50% in patients with <50% CD3 CD8 IELs and monoclonal TCR, respectively. Clinical worsening was more frequent (100%) among patients harboring a monoclonal TCR gene rearrangement with <50% CD3 CD8 IELs. These patients also showed shorter median time to clinical worsening (11 mo) when compared to patients with <50% CD3 CD8 IELs alone (21 mo), polyclonal TCR (38 mo), or >50% CD3 CD8 IELs alone (66 mo). After adjusting for age and gender, only the presence of <50% CD3 CD8 IELs was associated with increased risk for clinical worsening despite negative celiac serologies (hazard ratio=4.879; 95% confidence interval, 1.785-13.336; P=0.002). CONCLUSIONS Presence of <50% CD3 CD8 IELs is a risk factor for clinical worsening in RCD and combined with a monoclonal TCR gene rearrangement result is associated with increased mortality. IEL phenotype and TCR gene rearrangement analyses provide differential information regarding morbidity and mortality in RCD.

Is dietitian use associated with celiac disease outcomes? Nutrients 2013; 5:1585-94.

Abstract
A gluten-free diet (GFD) is the treatment for celiac disease (CD), but due to its complexity, dietitian referral is uniformly recommended. We surveyed patients with CD to determine if dietitian use is associated with quality of life, symptom severity, or GFD adherence. The survey utilized three validated CD-specific instruments: the CD quality of life (CD-QOL), CD symptom index (CSI) and CD adherence test (CDAT). Four hundred and thirteen patients with biopsy-proven CD were eligible for inclusion. The majority (77%) were female and mean BMI was 24.1. Over three-quarters of patients (326, 79%) had seen a dietitian, however, 161 (39%) had seen a dietitian only once. Age, sex, and education level were not associated with dietitian use; nor was BMI (24.6 vs. 24.0, p = 0.45). On multivariate analysis, adjusting for age gender, education, duration of disease, and body mass index, dietitian use was not associated with CD-QOL, CSI, or CDAT scores. Our survey did not show an association between dietitian use and symptom severity, adherence, or quality of life. Delay in diagnosis was associated with poorer outcomes. This is a preliminary study with several limitations, and further prospective analysis is needed to evaluate the benefits and cost-effectiveness of dietitian-referral in the care of celiac disease patients.

Abstract
INTRODUCTION Prognosis of enteropathy-associated T cell lymphoma is poor but predictors of survival remain ill-defined. How clinical presentation, pathological features and therapies influence outcome was evaluated in 37 thoroughly characterized patients with celiac disease and T-cell lymphoma. PATIENTS AND METHODS Medical files were studied retrospectively. Lymphoma and intestinal mucosa were analysed by histopathology, multiplex PCR and intestinal intraepithelial lymphocytes phenotyping. Survival and prognostic factors were analysed using Kaplan-Meier curves with Logrank test and Cox Model. RESULTS Lymphoma complicated non clonal enteropathy, celiac disease (n=15) and type I refractory celiac disease (n=2) in 17 patients and clonal type II refractory celiac disease in 20 patients. Twenty-five patients underwent surgery with resection of the main tumour mass in 22 cases. In univariate analysis, non clonal celiac disease, serum albumin level>21.6g/L at diagnosis, chemotherapy and surgical resection predicted good survival (p=0.0007, p<0.0001, p<0.0001, p<0.0001, respectively). In multivariate analysis, serum albumin level>21.6g/L, chemotherapy and reductive surgery were all significantly associated with increased survival (p<0.002, p<0.03, p<0.03, respectively). CONCLUSIONS Our study underlines the prognostic value of celiac disease type in patients with T-cell lymphoma, and suggests that a combination of nutritional, chemotherapy and reductive surgery may improve survival.

Abstract
GOALS AND BACKGROUND Discriminating between patients with nonresponsive but otherwise uncomplicated celiac disease (CD) and patients with refractory celiac disease (RCD) and/or lymphoma is difficult, especially as many abnormalities encountered in complicated CD are not within reach of conventional gastroduodenoscopy. We aimed to describe video capsule endoscopy (VCE) findings in patients with CD and persisting or relapsing symptoms despite a gluten-free diet and to identify VCE findings associated with poor prognosis. METHODS We retrospectively analyzed 48 VCE studies performed in adult patients with CD because of persisting or relapsing symptoms despite adherence to a gluten-free diet. Patients with either uncomplicated CD or RCD type I were considered to have a good prognosis, whereas patients with either RCD type II or enteropathy-associated T-cell lymphoma were considered to have a poor prognosis. Multivariate analysis was performed to identify VCE findings independently associated with either good or poor prognosis. RESULTS Proximal focal erythema (odds ratio, 6.7; 95% confidence interval, 1.2-38.7; P=0.033) and absence of progression of the capsule to the distal intestine (odds ratio, 16.5; 95% confidence interval, 1.2-224.9; P=0.035) were independently associated with poor prognosis. Of the 28 patients with none of these 2 features, none died during follow-up, compared with 2 (13.3%) of the 15 patients with one of both features, and 4 (80.0%) of the 5 patients with both the features. CONCLUSIONS VCE is a minimally invasive endoscopic modality that could be of use in identifying patients with nonresponsive CD who are at risk of poor prognosis.

Abstract
This guideline presents recommendations for the diagnosis and management of patients with celiac disease. Celiac disease is an immune-based reaction to dietary gluten (storage protein for wheat, barley, and rye) that primarily affects the small intestine in those with a genetic predisposition and resolves with exclusion of gluten from the diet. There has been a substantial increase in the prevalence of celiac disease over the last 50 years and an increase in the rate of diagnosis in the last 10 years. Celiac disease can present with many symptoms, including typical gastrointestinal symptoms (e.g., diarrhea, steatorrhea, weight loss, bloating, flatulence, abdominal pain) and also non-gastrointestinal abnormalities (e.g., abnormal liver function tests, iron deficiency anemia, bone disease, skin disorders, and many other protean manifestations). Indeed, many individuals with celiac disease may have no symptoms at all. Celiac disease is usually detected by serologic testing of celiac-specific antibodies. The diagnosis is confirmed by duodenal mucosal biopsies. Both serology and biopsy should be performed on a gluten-containing diet. The treatment for celiac disease is primarily a gluten-free diet (GFD), which requires significant patient education, motivation, and follow-up. Non-responsive celiac disease occurs frequently, particularly in those diagnosed in adulthood. Persistent or recurring symptoms should lead to a review of the patient's original diagnosis to exclude alternative diagnoses, a review of the GFD to ensure there is no obvious gluten contamination, and serologic testing to confirm adherence with the GFD. In addition, evaluation for disorders associated with celiac disease that could cause persistent symptoms, such as microscopic colitis, pancreatic exocrine dysfunction, and complications of celiac disease, such as enteropathy-associated lymphoma or refractory celiac disease, should be entertained. Newer therapeutic modalities are being studied in clinical trials, but are not yet approved for use in practice. Given the incomplete response of many patients to a GFD-free diet as well as the difficulty of adherence to the GFD over the long term, development of new effective therapies for symptom control and reversal of inflammation and organ damage are needed. The prevalence of celiac disease is increasing worldwide and many patients with celiac disease remain undiagnosed, highlighting the need for improved strategies in the future for the optimal detection of patients.

Abstract
A significant proportion of patients with coeliac disease are 'nonresponsive' to gluten withdrawal. Most cases of nonresponsive coeliac disease are due to persisting gluten ingestion. Refractory coeliac disease (RCD) is currently defined by persistent symptoms and signs of malabsorption after gluten exclusion for 12 months with ongoing intestinal villous atrophy. Primary (without initial response to diet) and secondary (relapse following response to diet) RCD is recognized. RCD is further classified as type I or type II based on the absence or presence of a population of aberrant intestinal lymphocytes. Quality of dietetic advice and support is fundamental, and lack of objective corroboration of gluten exclusion may result in over-identification of RCD I, particularly in those cases with persisting antibody responses. Over-reliance on lymphocyte clonality similarly may result in over-diagnosis of RCD II which requires careful quantification of aberrant lymphocyte populations. Management of RCD should be undertaken in specialist centres. It requires initial intensive dietary supervision, strict gluten exclusion and subsequent re-evaluation. There is currently insufficient evidence to recommend specific treatments. Steroids are often used in both RCD I and II (albeit with little objective evidence of benefit in RCD II), and azathioprine as steroid-sparing therapy in RCD I. There is growing evidence for the use of cladribine in RCD II with autologous stem cell transplantation in nonresponders, but this requires further multicentre evaluation. There remains considerable controversy regarding the diagnosis, treatment and surveillance of RCD: international consensus in these areas is urgently required to facilitate future therapeutic advances.

Abstract
The increasing use of immunohistochemical and molecular investigations of lymphatic tissues results in more frequent detection of early lymphoid proliferations. These show some but not all features of malignant lymphomas without fulfilling the diagnostic criteria for the diagnosis of lymphoid malignancy. In addition to well-known premalignant B-cell proliferations, such as monoclonal gammopathy of unknown significance (MGUS) and monoclonal B-cell lymphocytosis (MBL), so-called in situ lymphomas have recently been described with minimal infiltrates of clonal B-cells in morphologically reactive lymphoid tissues which show the phenotypic and genetic features of specific B-cell lymphoma subtypes and often show a characteristic topographical distribution. This article addresses a group of clonal lymphoproliferations with usually localized disease and excellent clinical prognosis, such as pediatric follicular lymphoma and nodal marginal zone lymphoma. Another group of early lesions not addressed in this review are virally induced lymphoproliferations which represent a grey zone between purely reactive lesions and malignant lymphomas and may pose significant diagnostic as well as clinical problems. In this review diagnostic criteria for early or in situ lesions and their distinction from partial infiltration by malignant lymphoma are described.

Abstract
Celiac disease (CD) is associated with both lymphoproliferative malignancy (LPM) and increased death from LPM. Research suggests that co-existing autoimmune disease may influence survival in LPM. Through Cox regression we examined overall and cause-specific mortality in 316 individuals with CD+LPM versus 689 individuals with LPM only. CD was defined as having villous atrophy according to biopsy reports at any of Sweden's 28 pathology departments, and LPM as having a relevant disease code in the Swedish Cancer Register. During follow-up, there were 551 deaths (CD: n = 200; non-CD: n = 351). Individuals with CD+LPM were at an increased risk of death compared with LPM-only individuals [adjusted hazard ratio (aHR) = 1.23; 95% confidence interval (CI) = 1.02-1.48]. However, this excess risk was only seen in the first year after LPM diagnosis (aHR = 1.76), with HRs decreasing to 1.09 in years 2-5 after LPM diagnosis and to 0.90 thereafter. Individuals with CD and non-Hodgkin lymphoma (NHL) were at a higher risk of any death as compared with NHL-only individuals (aHR = 1.23; 95% CI = 0.97-1.56). This excess risk was due to a higher proportion of T cell lymphoma in CD patients. Stratifying for T- and B cell status, the HR for death in individuals with CD+NHL was 0.77 (95% CI = 0.46-1.31). In conclusion, we found no evidence that co-existing CD influences survival in individuals with LPM. The increased mortality in the first year after LPM diagnosis is related to the predominance of T-NHL in CD individuals. Individuals with CD+LPM should be informed that their prognosis is similar to that of individuals with LPM only. However, this study had low statistical power to rule our excess mortality in patients with CD and certain LPM subtypes.

Abstract
BACKGROUND Enterocyte damage is the hallmark of coeliac disease (CD) resulting in malabsorption. Little is known about the recovery of enterocyte damage and its clinical consequences. Serum intestinal fatty acid binding protein (I-FABP) is a sensitive marker to study enterocyte damage. AIMS To evaluate the severity of enterocyte damage in adult-onset CD and its course upon a gluten-free diet (GFD). Furthermore, the correlation among enterocyte damage, CD autoantibodies and histological abnormalities during the course of disease is studied. METHODS Serum I-FABP levels were determined in 96 biopsy-proven adult CD patients and in 69 patients repeatedly upon a GFD. A total of 141 individuals with normal antitissue transglutaminase antibody (IgA-tTG) levels served as controls. I-FABP levels were related to the degree of villous atrophy (Marsh grade) and IgA-tTG. RESULTS I-FABP levels were elevated in untreated CD (median 691 pg/mL) compared with controls (median 178 pg/mL, P < 0.001) and correlated with Marsh grade (r = 0.265, P < 0.05) and IgA-tTG (r = 0.403, P < 0.01). Upon a GFD serum levels decreased significantly, however, not within the range observed in controls, despite the common observed normalisation of IgA-tTG levels and Marsh grade. CD patients with elevated I-FABP levels nonresponding to GFD showed persistent histological abnormalities. CONCLUSIONS Enterocyte damage assessed by serum I-FABP correlates with the severity of villous atrophy in coeliac disease at the time of diagnosis. Although enterocyte damage improves upon treatment, substantial enterocyte damage persists despite absence of villous atrophy and low IgA-tTG levels in the majority of cases. Elevated I-FABP levels nonresponding to gluten-free diet are indicative of histological abnormalities and warrant further evaluation.

Abstract
BACKGROUND Coeliac disease (CD), characterised by the presence of villous atrophy (VA) in the small intestine, is associated with increased mortality, but it is unknown if mortality is influenced by mucosal recovery. AIMS To determine whether persistent VA is associated with mortality in CD. METHODS Through biopsy reports from all pathology departments (n = 28) in Sweden, we identified 7648 individuals with CD (defined as VA) who had undergone a follow-up biopsy within 5 years following diagnosis. We used Cox regression to examine mortality according to follow-up biopsy. RESULTS The mean age of CD diagnosis was 28.4; 63% were female; and the median follow-up after diagnosis was 11.5 years. The overall mortality rate of patients who underwent follow-up biopsy was lower than that of those who did not undergo follow-up biopsy (Hazard Ratio 0.88, 95% CI: 0.80-0.96). Of the 7648 patients who underwent follow-up biopsy, persistent VA was present in 3317 (43%). There were 606 (8%) deaths. Patients with persistent VA were not at increased risk of death compared with those with mucosal healing (HR: 1.01; 95% CI: 0.86-1.19). Mortality was not increased in children with persistent VA (HR: 1.09 95% CI: 0.37-3.16) or adults (HR 1.00 95% CI: 0.85-1.18), including adults older than age 50 years (HR: 0.96 95% CI: 0.80-1.14). CONCLUSIONS Persistent villous atrophy is not associated with increased mortality in coeliac disease. While a follow-up biopsy will allow detection of refractory disease in symptomatic patients, in the select population of patients who undergo repeat biopsy, persistent villous atrophy is not useful in predicting future mortality.

Abstract
OBJECTIVES The aims of this research were to determine the number of chromosomal aberrations in peripheral blood lymphocytes and to evaluate the number of circulating lymphocytes with CD103, integrin expressed on intraepithelial lymphocytes and preserved in enteropathy-associated T-cell lymphoma, in patients with newly diagnosed Crohn's disease, celiac disease, and healthy controls. METHODS During the period of 30 months, we included 44 patients. Chromosome aberrations were analyzed in peripheral blood lymphocytes by a single cytogeneticist. Multicolor flow cytometric was used for immunophenotyping of peripheral blood lymphocytes. RESULTS We found a significantly higher number of chromosomal aberrations/100 metaphases in the celiac and Crohn's disease group compared with the controls (P=0.01) and they also had a significantly higher number of aberrant cells compared with the controls (P<0.001). There was no statistically significant difference between the groups with respect to the percentage of CD103+ and CD8+CD103+ cells between groups (P=0.16 and 0.41, respectively) and no correlation between the total number of chromosomal aberrations and the percentage of CD103+ and CD8+CD103+ cells (P=0.06 and 0.06, respectively). CONCLUSION Patients with active celiac and newly diagnosed Crohn's disease, before treatment initiation, have a significantly increased number of chromosomal aberrations in peripheral blood lymphocytes. No dissemination of intraepithelial cells in the blood and correlation to the chromosomal aberration was found.

Abstract
Celiac disease, an autoimmune disease once thought to be uncommon, is now being increasingly identified. Our improved diagnostic modalities have allowed us to diagnose more and more patients with atypical symptoms who improve on gluten-free diet (GFD). We discuss here the latest findings regarding the various hematological manifestations of celiac disease and their management. Anemia remains the most common hematological manifestation of celiac disease due to many mechanisms, and can be the sole presenting symptom. Other manifestations include thrombocytosis and thrombocythemia, leukopenia, thromboembolism, increased bleeding tendency, IgA deficiency, splenic dysfunction, and lymphoma. The diagnosis of celiac disease should always be kept in mind when a patient presents with unexplained and isolated hematological finding. Once diagnosed, patients should adhere to GFD and be educated about the potential complications of this disease. We herein present an algorithm for adequate management and follow-up.

Abstract
Large granular lymphocyte leukemia (LGL) is characterized by clonal expansion of CD3+ T cells or CD3(-) natural killer cells and frequently is associated with autoimmune diseases. We describe 2 patients with celiac disease who no longer responded to gluten-free diets after they developed T-cell LGL, with intestinal localization of malignant lymphocytes. Flow cytometry phenotyping of isolated intestinal intraepithelial and lamina propria cells eliminated type II refractory celiac disease, identifying large-sized CD8(+)CD57(+) T cells. Treatment with a combination of cyclosporine and methotrexate restored the patients' sensitivity to gluten-free diets. LGL therefore might be a cause of refractory celiac disease that is sensitive to immunosuppressive therapy.

Abstract
BACKGROUND Identification of adjuvant treatment is necessary for rapid and effective treatment in patients with celiac disease. In a pilot randomized controlled trial, the effect of prednisolone on enterocyte apoptosis and regeneration in celiac disease was investigated. PATIENTS AND METHODS Thirty-three treatment-naïve patients with celiac disease were randomized to either gluten-free diet (GFD, n = 17) or GFD + prednisolone (1 mg/kg for 4 weeks, n = 16). Duodenal biopsies were taken at baseline and at 4 and 8 weeks posttreatment. Six patients with functional dyspepsia were recruited as controls. All these biopsies were stained for markers of intrinsic apoptotic pathway (AIF, H2AX, p53), common apoptotic pathway (CC3, M30), apoptotic inhibitors (XIAP, Bcl2), and epithelial proliferation (Ki-67). Apoptotic (AI) and proliferation indices (PI) were compared. RESULTS At baseline duodenal biopsies, the end apoptotic products H2AX and M30 were significantly increased. In comparison with those treated with GFD alone, after 4 weeks of GFD + prednisolone treatment, some markers of both intrinsic and common apoptotic pathways showed rapid decline. After prednisolone withdrawal, there was overexpression of H2AX, CC3, and p53 in the latter group. In comparison with those treated with only GFD, patients treated with prednisolone showed suppression of mucosal PI, which started rising again after withdrawal of prednisolone. CONCLUSIONS Apoptosis takes place in mucosal epithelium in celiac disease. Addition of short course of prednisolone suppresses apoptosis rapidly. However, it also suppresses epithelial regeneration; hence, if used, it should be withdrawn after an initial short course.

Abstract
Celiac disease (CD) is one of the most common diseases, resulting from both environmental (gluten) and genetic factors [human leukocyte antigen (HLA) and non-HLA genes]. The prevalence of CD has been estimated to approximate 0.5%-1% in different parts of the world. However, the population with diabetes, autoimmune disorder or relatives of CD individuals have even higher risk for the development of CD, at least in part, because of shared HLA typing. Gliadin gains access to the basal surface of the epithelium, and interact directly with the immune system, via both trans- and para-cellular routes. From a diagnostic perspective, symptoms may be viewed as either "typical" or "atypical". In both positive serological screening results suggestive of CD, should lead to small bowel biopsy followed by a favourable clinical and serological response to the gluten-free diet (GFD) to confirm the diagnosis. Positive anti-tissue transglutaminase antibody or anti-endomysial antibody during the clinical course helps to confirm the diagnosis of CD because of their over 99% specificities when small bowel villous atrophy is present on biopsy. Currently, the only treatment available for CD individuals is a strict life-long GFD. A greater understanding of the pathogenesis of CD allows alternative future CD treatments to hydrolyse toxic gliadin peptide, prevent toxic gliadin peptide absorption, blockage of selective deamidation of specific glutamine residues by tissue, restore immune tolerance towards gluten, modulation of immune response to dietary gliadin, and restoration of intestinal architecture.

Abstract
OBJECTIVES Capsule endoscopy (CE) allows for the assessment of the small bowel in numerous intestinal diseases, including celiac disease (CD). The main advantage of CE is the complete visualization of the intestinal mucosal surface. The objective of this study was to investigate whether CE can predict the severity of CD and detect complications. METHODS We retrospectively studied the medical files of 9 patients with symptomatic CD, 11 patients with refractory celiac disease type I (RCDI) and 18 patients with refractory celiac disease type II (RCDII), and 45 patients without CD who were investigated both CE and upper endoscopy or enteroscopy. The type of CD was diagnosed on the basis of a centralized histological review, flow cytometry analysis of intraepithelial lymphocytes, and the analysis of T-cell receptor rearrangement by multiplex polymerase chain reaction. RESULTS A total of 47 CEs (10, 11, and 26 CEs in the symptomatic CD, RCDI, and RCDII groups, respectively) from the 38 celiac patients and 47 CEs from the 45 nonceliac patients were retrospectively reviewed. Villous atrophy, numerous, or distally located ulcers were more frequent in celiac patients than in controls. Among celiac patients, CE was of acceptable quality in 96% of cases and was complete in 62% of cases. The concordance of CE with histology for villous atrophy was better than that of optic endoscopy (κ coefficient =0.45 vs. 0.24, P<0.001). Extensive mucosal damage on CE was associated with low serum albumin (P=0.003) and the RCDII form (P=0.02). Three cases of overt lymphoma were detected by CE during the follow-up. CONCLUSIONS CE findings have a satisfactory concordance with histology and nutritional status in patients with symptomatic or refractory CD. Moreover, CE may predict the type of RCD and allows for the early detection of overt lymphoma.

Abstract
This article reviews the risk of mortality and malignancy in celiac disease (CD) and examines the evidence of the protective effect of a gluten-free diet (GFD) on mortality and malignancy. Population-based studies have confirmed that patients with diagnosed CD are at increased risk of mortality. However, patients with CD do not seem to be at an increased risk of malignancy, except for an increased risk of lymphoproliferative malignancy and gastrointestinal cancer. The evidence that a GFD reduces the risk of mortality is weak, but there is some evidence suggesting that a GFD may reduce the risk of lymphoproliferative malignancy.

Abstract
Celiac disease is a common inflammatory disease of the small intestine triggered by gluten in genetically susceptible individuals. Diagnosis is made by serologic testing and upper endoscopy with small bowel biopsy in most individuals. Celiac patients may present with abdominal pain or nonspecific gastrointestinal complaints that result in radiologic imaging before diagnosis of celiac disease. Wireless video capsule endoscopy, device-assisted enteroscopy, and enterography allow careful examination of the entire small bowel and targeted sampling of suspicious lesions. This review focuses on the role of device-assisted enteroscopy and radiologic imaging, in particular enterography, in celiac disease.

Abstract
Small bowel biopsy remains the gold standard for diagnosing celiac disease (CD). Intraepithelial lymphocytosis in the context of villous atrophy is considered a characteristic histologic finding of CD. However, studies have also indicated that the detection of intraepithelial lymphocytosis in the absence of villous atrophy is not specific for CD, having been documented in other small intestinal disorders. This review summarizes key aspects regarding the histopathologic assessment, impact of the site and number of small bowel biopsy samples on diagnosis, old and emerging classifications, and benefit of standardized pathology report in the diagnostic workup of CD.

Abstract
Celiac disease results from the interplay of genetic, environmental, and immunologic factors. An understanding of the pathophysiology of celiac disease, in which the trigger (wheat, rye, and barley) is known, will undoubtedly reveal basic mechanisms that underlie other autoimmune diseases (eg, type 1 diabetes) that share many common pathogenic perturbations. This review describes seminal findings in each of the 3 domains of the pathogenesis of celiac disease, namely genetics, environmental triggers, and immune dysregulation, with a focus on newer areas of investigation such as non-HLA genetic variants, the intestinal microbiome, and the role of the innate immune system.

Abstract
Video capsule endoscopy (VCE) provides a safe, non-invasive way to visualize the small intestine and is helpful in celiac disease patients in select situations. VCE can be performed in patients who are unable or unwilling to undergo conventional endoscopy, those with positive celiac serology with normal duodenal biopsies, and also in those who develop alarm symptoms. VCE has limitations including subjective interpretation. Techniques are being developed to standardize assessment of VCE images in patients with known or suspected celiac disease. Pilot studies using computer-based quantification methods have shown promise in examining the 3-dimensional mucosal structure and motility.

Abstract
A small subset of patients with celiac disease become refractory to a gluten-free diet, with persistent or recurrent symptoms of malabsorption and intestinal villous atrophy. This condition, defined as refractory celiac disease (RCD), is diagnosed after other small bowel diseases with villous atrophy are excluded. RCD is subdivided into 2 subgroups: type I RCD and type II RCD (RCDII). This latter condition is considered a low-grade intraepithelial lymphoma and has a poor prognosis. This article reviews the clinical and pathologic features of RCD and recent pathogenic findings in RCDII, offering a model to study how inflammation can drive T-cell lymphomagenesis.

Abstract
CONTEXT Celiac disease (CD) is a common immune-mediated disorder that occurs in genetically predisposed individuals (carriers of HLA-DQ2 and DQ8 haplotypes) on consumption of wheat (gluten). It is characterized by inflammation of the small-intestinal mucosa and myriad gastrointestinal and systemic manifestations. Celiac disease is common in the general population (prevalence, 0.5%-1%). Currently, small-bowel biopsy is considered the gold standard for diagnosing CD. However, the role of serologic testing in the diagnosis of CD has evolved, from being a supportive test to supplanting intestinal biopsies in certain patient populations. OBJECTIVE To summarize key aspects of histopathologic assessment, discuss the benefit of standardized pathology reports, impact of the site and number of small-bowel biopsy samples on diagnosis, and recommendations regarding serologic testing. DATA SOURCES Literature review of publications on CD and experience with histopathologic review of biopsies at the Department of Pathology and Cell Biology, Columbia University Medical Center, New York-Presbyterian Hospital, New York. CONCLUSIONS Intraepithelial lymphocytosis in the context of villous atrophy is considered a characteristic histologic finding of CD; however, it is a rather nonspecific finding. A growing list of publications has also indicated that the detection of intraepithelial lymphocytosis in the absence of villous atrophy has rather low specificity for CD. Therefore, communication between pathologists and gastroenterologists is paramount, as is knowledge regarding the pertinent clinical and laboratory data, in distinguishing between CD and other disorders with similar histopathologic and clinical manifestations.

Abstract
Celiac disease (CD) is a chronic enteropathy induced by dietary gluten in genetically predisposed people. The keystone of CD pathogenesis is an adaptive immune response orchestrated by the interplay between gluten and MHC class II HLA-DQ2 and DQ8 molecules. Yet, other factors that impair immunoregulatory mechanisms and/or activate the large population of intestinal intraepithelial lymphocytes (IEL) are indispensable for driving tissue damage. Herein, we summarize our current understanding of the mechanisms and consequences of the undesirable immune response initiated by gluten peptides. We show that CD is a model disease to decipher the role of MHC class II molecules in human immunopathology, to analyze the mechanisms that link tolerance to food proteins and autoimmunity, and to investigate how chronic activation of IEL can lead to T cell lymphomagenesis.

Abstract
BACKGROUND Refractory celiac disease (RCD) is a preneoplastic condition as many patients develop an enteropathy-type T-cell lymphoma, a mature T-cell receptor α-β lymphoma arising in the gut with an ominous outcome. Recently, research focused on a population of intraepithelial intestinal lymphocytes expressing the same lymphoma T-cell receptor variable region (V)γ, as shown by polymerase chain reaction (PCR) analysis and sequencing. Meanwhile, the Biomedicine and Health-2 Concerted Action has made available standardized, highly specific, and sensitive PCR assays not only for Vγ but also for Vβ. GOALS We verified whether analyzing both rearrangements in duodenal biopsies from RCD patients increases the diagnostic accuracy of this method. STUDY Duodenal biopsies were analyzed from 15 RCD patients, 21 negative controls, and 2 positive controls (enteropathy-type T-cell lymphoma complicating celiac disease). Multiplex clonality analyses were performed according to the Biomedicine and Health-2 protocols. PCR products were cloned and sequenced. RESULTS Monoclonal rearrangements were found in 5/15 samples from patients with RCD (both rearrangements in 2 cases, Vβ only in 2, and only 1 solitary Vγ clonality). Monoclonality was found in 4/8 of the RCD patients who subsequently died, whereas only 1/7 of the patients still alive presented a monoclonal rearrangement. Positive controls revealed both monoclonal rearrangements; rearrangements were not detected in 20 of 21 negative controls. Sequencing of the amplified fragments confirmed the results. CONCLUSIONS The combined analysis of both rearrangements allowed recognition of monoclonal populations in otherwise negative patients, with detection rates from 20% (Vγ only) to 33% (Vγ and Vβ), thus raising the likelihood of early identification of RCD patients at high risk of death.

Abstract
BACKGROUND Refractory coeliac disease type I is a complicated form of coeliac disease characterised by primary or secondary resistance to a gluten-free diet with persisting or reoccurring intestinal villous atrophy and symptoms of malabsorption. Besides corticosteroids, azathioprine has been advocated for the treatment of refractory coeliac disease type I. However, tioguanine (TG) might be better tolerated and more efficacious owing to a simpler metabolism towards bioactivation. AIM To evaluate tolerability and effectiveness of the nonconventional thiopurine derivative TG in refractory coeliac disease type I. METHODS Refractory coeliac disease type I patients treated with TG between June 2001 and November 2010 with a follow-up period of at least 1 year were included. Adverse events, laboratory values, 6-thioguanine nucleotide concentrations and rates of both clinical and histological response were evaluated at baseline and during follow-up. RESULTS Twelve adult refractory coeliac disease type I patients were included. The median TG treatment duration was 14 months. Ten patients tolerated TG treatment on the long term, whereas two patients withdrew treatment due to adverse events. No nodular regenerative hyperplasia of the liver was observed. During follow-up clinical and histological response was observed in 83% and 78%, respectively. Corticosteroid dependency decreased by 50%. CONCLUSION Tioguanine appears to be a convenient drug for the treatment of refractory coeliac disease type I based on higher histological and similar clinical response rates as compared with historical conventional therapies.

Abstract
Refractory celiac disease is defined by the persistence of symptoms of malnutrition and intestinal villous atrophy for more than 6-12 months despite strict gluten-free diet in celiac patients. Diagnosis of this rare condition is made after excluding other causes of chronic small intestinal inflammation and villous atrophy and inadvertent intake of gluten. Over the past 15 years, multidisciplinary approaches have been developed to assess the mechanism of resistance to the diet, and two distinct entities have been delineated. Type II refractory celiac disease (RCD) can be defined as a low-grade intraepithelial lymphoma. RCD II is characterised by a massive accumulation of abnormal IEL that display an aberrant hybrid NK/T cell phenotype, contain clonal T cell rearrangement(s) and can mediate a cytolytic attack of the gut epithelium. This condition has a severe prognosis, largely due to the frequent transformation of RCDII IEL into overt aggressive enteropathy-type-associated T cell lymphoma. In contrast, in type I RCD, intestinal lymphocytes have a normal phenotype, and this generally milder condition remains often difficult to differentiate from uncomplicated CD except for the resistance to gluten-free diet (GFD). Several mechanisms may underlie resistance to gluten. Herein, we review the distinctive characteristics of RCD I and RCD II, the mechanisms underlying the onset of resistance to GFD, the risk of developing high grade lymphoma and possible clues to improve their treatment.

Abstract
The nonclassic clinical presentation of celiac disease (CD) becomes increasingly common in physician's daily practice, which requires an awareness of its many clinical faces with atypical, silent, and latent forms. Besides the common genetic background (HLA DQ2/DQ8) of the disease, other non-HLA genes are now notably reported with a probable association to atypical forms. The availability of high-sensitive and specific serologic tests such as antitissue transglutuminase, antiendomysium, and more recent antideamidated, gliadin peptide antibodies permits to efficiently uncover a large portion of the submerged CD iceberg, including individuals having conditions associated with a high risk of developing CD (type 1 diabetes, autoimmune diseases, Down syndrome, family history of CD, etc.), biologic abnormalities (iron deficiency anemia, abnormal transaminase levels, etc.), and extraintestinal symptoms (short stature, neuropsychiatric disorders, alopecia, dental enamel hypoplasia, recurrent aphtous stomatitis, etc.). Despite the therapeutic alternatives currently in developing, the strict adherence to a GFD remains the only effective and safe therapy for CD.

Abstract
Coeliac disease (CD) is a gluten-responsive, chronic inflammatory enteropathy that shares many features with classical autoimmune diseases. Coeliac disease affects about 1-2% of Caucasians, North Africans and Asians who possess the necessary susceptibility genes encoding HLA DQ2 or HLA DQ8. It is not only unique among the autoimmune diseases in that the precise trigger (gluten from wheat, rye and barley) has been identified, but also in that it has lent itself well to advancements in endoscopic imaging. Since its introduction, flexible endoscopy has allowed tissue to be collected from the small bowel with relative ease and safety, and recently has facilitated direct imaging and sampling of the entire small intestine. It is now fifty years since the Crosby capsule first allowed clinicians the ability to non-surgically biopsy the small bowel leading to an enhanced diagnosis of coeliac disease. The introduction of wireless video capsule endoscopy (VCE), small bowel enteroscopy and in particular double balloon enteroscopy (DBE), have expedited the accurate diagnosis of coeliac disease and its more serious complications such as small bowel adenocarcinoma, refractory coeliac disease type II (RCDII) and enteropathy associated T cell lymphoma (EATL).

Abstract
The increasing use of immunophenotypic and molecular techniques on lymphoid tissue samples without obvious involvement by malignant lymphoma has resulted in the increased detection of "early" lymphoid proliferations, which show some, but not all the criteria necessary for a diagnosis of malignant lymphoma. In most instances, these are incidental findings in asymptomatic individuals, and their biological behaviour is uncertain. In order to better characterize these premalignant conditions and to establish diagnostic criteria, a joint workshop of the European Association for Haematopathology and the Society of Hematopathology was held in Uppsala, Sweden, in September 2010. The panel reviewed and discussed more than 130 submitted cases and reached consensus diagnoses. Cases representing the nodal equivalent of monoclonal B-cell lymphocytosis (MBL) were discussed, as well as the "in situ" counterparts of follicular lymphoma (FL) and mantle cell lymphoma (MCL), topics that also stimulated discussions concerning the best terminology for these lesions. The workshop also addressed the borderland between reactive hyperplasia, and clonal proliferations such as pediatric marginal zone lymphoma and pediatric FL, which may have very limited capacity for progression. Virus-driven lymphoproliferations in the grey zone between reactive lesions and manifest malignant lymphoma were covered. Finally, early manifestations of T-cell lymphoma, both nodal and extranodal, and their mimics were addressed. This workshop report summarizes the most important conclusions concerning diagnostic features, as well as proposals for terminology and classification of early lymphoproliferations and tries to give some practical guidelines for diagnosis and reporting.

Abstract
INTRODUCTION Enteropathy-associated T-cell lymphoma is a rare form of T-cell lymphoma associated with a poor prognosis and the relative ineffectiveness of standard chemotherapy. The occurrence of haemophagocytic lymphohistiocytosis has been reported only once with this entity. PATIENTS AND METHODS A retrospective study of 15 patients with enteropathy-associated T-cell lymphoma (type 1 in 12), followed-up in our units, since 1985. Two patients died before starting chemotherapy. The remaining 13 patients were treated with standard chemotherapy (n=7) and purine nucleotide analogues (n=6). RESULTS Median follow-up was 8.7 (1-97) months. Surgery was required in 10 patients (66%) for intestinal complications (n=7) or elective small bowel resection (n=3). Survival probability was 40% and 20% at 1 and 5 years, respectively (Kaplan-Meier method). Survival was not significantly different between the two chemotherapy regimens. However, a slight decrease of febrile neutropenia was observed in the purine nucleotide analogues group (p=0.06). Haemophagocytic lymphohistiocytosis occurred in 6/15 (40%) cases. In these six patients, haemophagocytic lymphohistiocytosis was always fatal within 3 months. CONCLUSION Enteropathy-associated T-cell lymphoma is associated with a poor outcome, independently of the chemotherapy regimens administered and frequent occurrence of haemophagocytic lymphohistiocytosis. The latter complication should be considered for urgent rescue therapy.

Abstract
Enteropathy-associated T-cell lymphoma (EATL) is a rare non-Hodgkin lymphoma frequently associated with celiac disease. We report a case of EATL complicating adult autoimmune enteropathy (AIE). Analysis of phenotype, rearrangements in T-cell receptor genes, and chromosome alterations by high-resolution comparative genomic hybridization identified features distinct from those described for types I and II EATL. Furthermore, EATL arose from a single T-cell clone that had been present for several years in AIE-associated, oligoclonal, intestinal T-cell infiltrate. Emerging T-cell clones should be monitored in patients with AIE who receive long-term immunosuppressive therapy.

Abstract
OBJECTIVES Regulatory T cells (Tregs) are instrumental for tolerance to self-antigens and dietary proteins. We have previously shown that interleukin (IL)-15, a cytokine overexpressed in the intestine of patients with celiac disease (CD), does not impair the generation of functional Tregs but renders human T cells resistant to Treg suppression. Treg numbers and responses of intestinal and peripheral T lymphocytes to suppression by Tregs were therefore compared in CD patients and controls. METHODS Intraepithelial lymphocytes (IELs) and lamina propria lymphocytes (LPLs) were isolated from duodenal biopsy specimens of CD patients and controls. Concomitantly, CD4+CD25+ T lymphocytes (Tregs) were purified from blood. Responses of IELs and of LPLs, and peripheral lymphocytes (PBLs) to suppression by Tregs were tested by analyzing anti-CD3-induced proliferation and interferon (IFN)-γ production in the presence or absence of peripheral Tregs. Lamina propria and peripheral CD4+CD25+FOXP3+ T cells were assessed by flow cytometry. RESULTS Although percentages of CD4+CD25+FOXP3+ LPLs were significantly increased in patients with active CD, proliferation and IFN-γ production of intestinal T lymphocytes were significantly less inhibited by autologous or heterologous Tregs in CD patients than in controls (P < 0.01). In all tested CD patients, IEL were unable to respond to Tregs. Resistance of LPLs and PBLs to Treg suppression was observed in patients with villous atrophy who had significantly enhanced serum levels of IL-15 compared with patients without villous atrophy and controls. CONCLUSIONS Our results indicate that effector T lymphocytes from active CD become resistant to suppression by Tregs. This resistance might cause loss of tolerance to gluten, but also to self-antigens.

Abstract
AIM: To investigate all patients referred to our center with non-responsive celiac disease (NRCD), to establish a cause for their continued symptoms.
METHODS: We assessed all patients referred to our center with non-responsive celiac disease over an 18-mo period. These individuals were investigated to establish the eitiology of their continued symptoms. The patients were first seen in clinic where a thorough history and examination were performed with routine blood work including tissue transglutaminase antibody measurement. They were also referred to a specialist gastroenterology dietician to try to identift any lapses in the diet and sources of hidden gluten ingestion. A repeat small intestinal biopsy was also performed and compared to biopsies from the referring hospital where possible. Colonoscopy, lactulose hydrogen breath testing, pancreolauryl testing and computed tomography scan of the abdomen were undertaken if the symptoms persisted. Their clinical progress was followed over a minimum of 2 years.
RESULTS: One hundred and twelve consecutive patients were referred with NRCD. Twelve were found not to have celiac disease (CD). Of the remaining 100 patients, 45% were not adequately adhering to a strict gluten-free diet, with 24 (53%) found to be inadvertently ingesting gluten, and 21 (47%) admitting non-compliance. Microscopic colitis was diagnosed in 12% and small bowel bacterial overgrowth in 9%. Refractory CD was diagnosed in 9%. Three of these were diagnosed with intestinal lymphoma. After 2 years, 78 patients remained well, eight had continuing symptoms, and four had died.
CONCLUSION: In individuals with NRCD, a remediable cause can be found in 90%: with continued gluten ingestion as the leading cause. We propose an algorithm for investigation.

Abstract
Lymphomas of natural killer (NK) and T cell lineages are uncommon disorders, although as a group they are more usually encountered in Asia compared to Western populations. In part due to their rarity, diagnosis and classification of T cell lymphomas often pose a challenge to clinicians and pathologists. Although there are morphological features that are characteristic of certain subtypes, correct classification of NK and T cell neoplasms relies heavily on the immunophenotype. With few exceptions, non-random genetic alterations such as translocations are less often seen in T cell neoplasms, adding to the diagnostic difficulty. Given these limitations, pathological diagnosis and classification of NK and T cell lymphomas are anything but straightforward. This paper attempts to present a practical algorithmic approach for the general pathologist who is confronted with these neoplasms.

Abstract
OBJECTIVES Aberrant intra-epithelial lymphocytes (IELs) are the hallmark of refractory coeliac disease type II RCDII and considered a premalignant cell population from which aggressive enteropathy-associated T cell lymphoma (EATL) can evolve. The aim of this study was to gain further insight in the origin and characteristics of aberrant IELs by analysing T-cell receptor (TCR) rearrangements, and by immunophenotypic analysis of aberrant IELs. DESIGN Duodenal biopsies from 18 RCDII patients and three RCDII cell lines were analysed for the presence of TCR delta, gamma, and beta rearrangements. In addition, IELs isolated from biopsies derived from RCDII patients were phenotypically analysed. RESULTS Aberrant IELs showed an upregulated expression of granzyme B and decreased expression of PCNA. TCR rearrangements in the aberrant IEL population in biopsies of RCDII patients were heterogenic, which is most likely due to a variation in maturity. Similarly, RCDII cell lines displayed a heterogenic TCR rearrangement pattern. CONCLUSION Aberrant IELs originate from deranged immature T lymphocytes and display clear differentiation to a cytotoxic phenotype. Aberrant IELs displayed different stages of maturity between RCDII patients, of which only the patients harbouring the most mature aberrant IEL population developed an EATL.

Abstract
BACKGROUND Celiac sprue is an underdiagnosed chronic intestinal inflammatory disease. Probe-based confocal laser microscopy (CLM) is a novel endoscopic technique for in vivo inspection of the intestinal mucosa that has not been evaluated in celiac sprue yet. AIMS To develop CLM criteria most predictive of celiac pathology in a prospective pilot study. METHODS Twenty-one patients (male n = 5, f = 16, mean age 52 years) with established or suspected celiac sprue, seven of whom had confirmed active disease (Marsh III) and 14 duodenal normal mucosa. CLM images from 91 duodenal sites were assessed. CLM recordings were obtained next to Argon beamer labeled areas. Biopsies were taken from the same spots for precise histological matching. After establishing histology-correlated criteria on one sample per patient, the remaining CLM recordings from the same patients were randomized and blindly evaluated. RESULTS Villous atrophy and irregular appearing villi were most predictive of celiac pathology. Although the presence of crypts was diagnostic for celiac pathology, it was only recognized in 26.7% of celiac pathology sites. Using these criteria in the blinded assessment, the overall endoscopist's prediction of celiac sprue was accurate in 89.8% of all biopsy sites in 85.7% of all patients. Preliminary interobserver agreement testing villous atrophy, irregular villi, and crypts was poor (kappa 0.05 to 0.26). CONCLUSIONS Probe-based CLM criteria developed in this pilot trial appear promising for the detection of active celiac sprue. Preliminary interobserver variability was high, indicating a learning curve effect. Our criteria need validation in an independent patient population.

Abstract
Enteropathy-associated T-cell lymphoma (EATL) is a complication of celiac disease (CD). This tumor derives from the neoplastic transformation of aberrant intraepithelial T lymphocytes emerging in celiac patients unresponsive to a gluten-free diet. Poor adherence to a gluten-free diet, HLA-DQ2 homozygosity, and late diagnosis of CD are recognized as risk factors for malignant evolution of CD. Recurrence of diarrhea, unexplained weight loss, abdominal pain, fever, and night sweating should alert physicians to this complication. The suspicion of EATL should lead to an extensive diagnostic workup in which magnetic resonance enteroclysis, positron emission tomography scan, and histologic identification of lesions represent the best options. Treatment includes high-dose chemotherapy preceded by surgical resection and followed by autologous stem cell transplantation, although biologic therapies seem to be promising. Strict adherence to a gluten-free diet remains the only way to prevent EATL.

Abstract
Enteropathy-associated T-cell lymphoma (EATL) is a rare non-Hodgkin lymphoma of T-cell origin. The recent 2008 World Health Organization classification of hematologic malignancies distinguishes between two types of EATL. The disease is associated with celiac disease, particularly with its late, adult onset. Currently, there are no standardized diagnostic or treatment protocols for EATL, mostly because of its rarity. Historically, the patients have been treated with anthracycline-based chemotherapy with or without surgery. The outcome of patients with EATL treated with these approaches is poor. The reported death rates in the biggest studies are approximately 80-84%, with median progression-free survival (PFS) of 3.4-6.0 months and overall survival of 7.1-10.0 months. The 5-year PFS ranged from 3.2% to 18% and OS from 19.7% to 20%. The results of a novel induction regimen with ifosfamide, etoposide, and epirubicin alternating with intermediate-dose methotrexate followed by autologous stem cell transplantation (ASCT) are more promising, with a 5-year PFS of 52% and OS of 60%. The alternative approach, with a more common induction with cyclophosphamide, doxorubicin, vincristine, etoposide, and prednisone followed by ASCT has also delivered promising results, with a 3-year PFS of 52% and OS of 47%. This review summarizes recently published data on epidemiology and clinical features, as well as standard and novel treatments including high-dose chemotherapy with ASCT and their outcome in EATL.

Abstract
The prevalence of celiac disease is rising. As a result there is increasing interest in the associated mortality and morbidity of the disease. Screening of asymptomatic individuals in the general population is not currently recommended; instead, a strategy of case finding is the preferred approach, taking into account the myriad modes of presentation of celiac disease. Although a gluten-free diet is the treatment of choice in symptomatic patients with celiac disease, there is no consensus on whether institution of a gluten-free diet will improve the quality of life in asymptomatic screen-detected celiac disease patients. A review of the studies that have been performed on this subject is presented. Certain patient groups such as those with autoimmune diseases may be offered screening in the context of an informed discussion regarding the potential benefits, with the caveat that the data on this issue are sparse. Active case finding seems to be the most prudent option in most clinical situations.
