Abstract
Enteropathy-type T-cell lymphoma (ETL) and ulcerative jejunitis (UJ) are rare disorders often occurring in patients with coeliac disease. The genetic events associated with the accumulation of intraepithelial lymphocytes in coeliac disease and tumour development are largely unknown. Deletions at chromosome 9p21, which harbours the tumour suppressor genes p14/ARF, p15/INK4b, and p16/INK4a, and 17p13, where p53 is located, are associated with the development and progression of lymphomas. To examine whether deletions at 9p21 and 17p13 play a role in ETL, 22 cases of ETL and seven cases of UJ were screened for loss of heterozygosity (LOH) by tissue microdissection and polymerase chain reaction (PCR) analysis for microsatellite markers. Furthermore, p53 and p16 protein expression was examined by immunohistochemistry. In addition, polymerase chain reaction-single strand conformational polymorphism (PCR-SSCP) analysis for detection of mutations in exons 5-8 of the p53 gene was performed in five cases of ETL and three cases of UJ. LOH was found in at least one microsatellite marker at the 9p21 locus in 8 of 22 (36%) ETLs, but not in UJ. Five of nine (56%) tumours composed of large cells showed LOH at 9p21, as opposed to two of eight (25%) tumours with small- or medium-sized cell morphology. The region spanning the p14/p15/p16 gene locus was most frequently affected (five cases); LOH at these markers coincided with loss of p16 protein expression in all of these cases. p53 overexpression was demonstrated in all ETLs examined and in four of seven cases of UJ. However, no alterations of the p53 gene were detected by LOH or PCR-SSCP analysis. The results of this study show that LOH at chromosome 9p21 is frequent in ETL, especially in tumours with large cell morphology; this finding suggests that gene loss at this locus may play a role in the development of ETL.

Abstract
Refractory celiac disease denotes that patients considered to have celiac disease fail to respond histologically to treatment with a gluten-free diet. Among several causes of nonresponsiveness, enteropathy-type T-cell lymphoma is most important because of its almost invariably rapid lethal outcome. We present the case of a 44-year-old patient with refractory celiac disease complicated by unusually severe malabsorption. Repeated duodenal biopsies disclosed normal and slightly shortened villi, focal crypt hypertrophy, and a moderate increase of intraepithelial lymphocytes consistent with celiac disease, but unable to explain the severe malabsorption. To rule out cryptic lymphoma, push enteroscopy was done providing 21 biopsies taken along the entire jejunum. Surprisingly, about 70% of the biopsies were composed of gastric glands covered by nonabsorptive-type, strongly periodic acid-Schiff-positive surface epithelium and showed a villous architecture. Alternating with the gastric mucosa, there were areas of flat mucosa with elongated crypts and occasional erosions. Irrespective of the type of surface epithelium, intraepithelial lymphocytes were increased with counts up to 80/100 epithelial cells. Despite harboring an aberrant immunophenotype, overt T-cell lymphoma was ruled out histologically and by lack of monoclonality, as tested by polymerase chain reaction. To the best of our knowledge, this is the first case of refractory celiac disease complicated by extensive jejunal gastric heterotopia, which might have contributed to the severe malabsorption.

Abstract
OBJECTIVES Children with coeliac disease (CD) have an increased number of chromosome aberrations in peripheral blood lymphocytes. Whether genetically determined or a secondary phenomenon in CD, chromosome abnormalities may be involved in the predisposition to cancer in CD patients. The aim of the study was to follow a group of children with CD in whom the initial frequency of chromosome aberrations at diagnosis was known and to measure the same variable after a minimum of 2 years on a gluten-free diet. METHODS Chromosome aberrations in peripheral blood lymphocytes were determined in 17 patients with CD, before and after at least 24 months of a gluten free diet (mean, 33 months), and in 15 healthy children. The differences in the frequency of aberrations were analyzed by Mann-Whitney U test and Wilcoxon matched-pairs signed-ranks test. RESULTS Twelve patients adhered to the diet and had a significantly lower frequency of chromosome aberrations than did 5 patients not following the diet (0.16% v 1.2%; P = 0.03), whereas at presentation there had been no difference (1.54% v 1.2%; P = 0.09). The frequency of aberrations at follow-up in patients who were diet adherent was significantly lower than at presentation (1.54% v 0.16%; P = 0.02) and remained unchanged in patients who were not diet adherent (1.2% v 1.2%; P = 1). After at least 24 months of a gluten-free diet, children with CD did not differ from healthy control subjects (0.16% v 0.27%; P = 0.54), whereas children not following the diet had an increased frequency of aberrations (1.2% v 0.27%; P = 0.05). CONCLUSIONS The frequency of chromosome aberrations in peripheral blood lymphocytes of patients with CD decreased significantly on a gluten-free diet. We conclude that genomic instability is a secondary phenomenon, possibly caused by chronic intestinal inflammation.

Abstract
OBJECTIVES Telomeres are important structures that are critical for maintaining chromosomal integrity and cell surveillance. The aim of this study was to analyze telomere length in patients with celiac disease (CD), a multifactorial disorder with a strong genetic component that exhibits genomic instability and cancer predisposition, particularly T-cell lymphomas. METHODS Telomere length measured by telomere restriction fragments (TRF) was studied in small intestinal biopsy (SIB) samples and peripheral blood lymphocytes (PBL) from 20 untreated CD patients, distributed according to the clinical form as four asymptomatic, five monosymptomatic, and 11 polysymptomatic individuals. We also analyzed TRF from normal peripheral blood lymphocytes and normal biopsy samples as normal controls. RESULTS TRF evaluation showed a significant telomere shortening in SIB samples from CD patients (4.21 +/- 0.29 Kb) compared to PBL from the same individuals (9.17 +/- 0.35 Kb) (p < 0.0001), independently of clinical form. Mean TRF peak values from normal biopsy samples were significantly higher (8.33 +/- 0.38 Kb) than those observed in CD biopsy samples (p < 0.001). No differences between TRF values in CD-PBL and normal peripheral blood lymphocytes (8.89 +/- 0.37Kb) were found. CONCLUSIONS Our findings in patients with CD, a disorder in which the gluten-induced mucosal injury could accelerate telomere shortening, would increase the process of end-to-end fusions resulting in chromosomal changes, supports the hypothesis that genomic instability and telomere reduction may play a role in the cancer predisposition observed in these patients.

Abstract
Celiac disease is a T cell-mediated disorder that results from intolerance to gluten. The major cause of failure to respond to a gluten-free diet is continuing gluten ingestion. In poorly responsive patients diagnosis of refractory sprue can be established after exclusion of a limited number of conditions. Refractory sprue may occur after an initial response to the diet or without evidence of preexisting celiac disease. The detection of aberrant, clonally expanded, intraepithelial lymphocytes has led to better definition and classification of patients with refractory sprue. Only a few series of patients with well-characterized refractory sprue have been reported in the literature. The prognosis is poor, though some patients respond to corticosteroids and immunosuppressive agents. The presence of an aberrant clonal intraepithelial T-cell population has led to the designation of refractory sprue as a cryptic intestinal T-cell lymphoma.

Abstract
INTRODUCTION Refractory coeliac disease (RCD) is a rare syndrome with a poor prognosis, defined by malabsorption due to gluten-related enteropathy after initial or subsequent failure of a strict gluten-free diet and after exclusion of any disorder mimicking coeliac disease. PATIENTS AND METHODS Nineteen patients were included and treated. Based on intraepithelial T-lymphocyte(IEL) phenotyping, patients were recorded as having RCD type I with normal IELs, or RCD type II with phenotypically immature IELs defined by a lack of characteristic T-cell markers. Treatment consisted of azathioprine combined with prednisone for 1 year, which was tapered and, if possible, stopped. RESULTS Clinical improvement was seen in nearly all patients in both groups. Eight of 10 RCD type I patients responded histologically, and complete normalization of villi was seen in four patients. In RCD type II, 6/8 patients developed enteropathy-associated T-cell lymphoma (EATL) and 7/8 patients died. CONCLUSIONS For the first time we report a promising therapeutic treatment option for RCD type I. In RCD type II, azathioprine and prednisone therapy (APT) is not effective, therefore we suggest that other (chemo)therapeutic agents are considered. Not all RCD type II patients presented with a monoclonal TCRgamma-gene rearrangement and immunohistological changes as is currently reported in the literature. Therefore, immunophenotyping seems mandatory in the work-up of RCD.

Abstract
BACKGROUND & AIMS The mechanism of intraepithelial lymphocyte hyperplasia, a hallmark of celiac disease, is unknown. We have investigated the role of epithelium-derived interleukin (IL)-15 in the alterations of epithelial homeostasis in refractory celiac sprue, a privileged situation to study the first step of lymphoid transformation and the contribution of intraepithelial lymphocytes to villous atrophy in celiac disease. METHODS IL-15 expression was assessed in biopsy specimens and isolated enterocytes by combining immunohistochemistry, flow cytometry, and real-time quantitative polymerase chain reaction. The ability of IL-15 to induce growth and survival of clonal intraepithelial lymphocytes lacking surface CD3 and to induce their cytotoxicity and secretion of interferon gamma was tested using soluble IL-15 and coculture in the presence of epithelial cell lines expressing membrane IL-15. RESULTS IL-15 was massively overexpressed not only in lamina propria but also in the intestinal epithelium of patients with active celiac disease and refractory celiac sprue. IL-15 was not secreted but delivered at the surface of enterocytes. IL-15 specifically induced the expansion and survival of the clonal abnormal intraepithelial lymphocytes that characterize refractory celiac sprue and triggered their secretion of interferon gamma and their cytotoxicity against intestinal epithelial cells. Comparable activating signals could be delivered by IL-15 expressed at the membrane of the T84 enterocyte cell line. CONCLUSIONS These data provide strong evidence that uncontrolled overexpression of IL-15 in refractory celiac sprue perpetuates epithelial damage and promotes the emergence of T-cell clonal proliferations. Blocking IL-15 might prove useful to treat this severe complication of celiac disease.

Abstract
BACKGROUND & AIMS Asymptomatic children at risk for celiac disease (CD) and seropositive for immunoglobulin A anti-TG autoantibodies (TGAA) may lack small intestinal mucosal changes characteristic of CD. We have followed a group of children with serial testing for TGAA. METHODS Subjects were a group of at-risk children comprised of infants expressing HLA-DR3 on newborn screening, those with type 1A diabetes, or a first-degree relative of someone with type 1 diabetes. All children participating in the prospective study for development of CD underwent serial testing for TGAA. Data from clinical evaluation and small intestinal biopsy were compared to the TGAA levels followed over time. RESULTS In 42 children, serial TGAA determinations while on a gluten-containing diet showed levels fluctuating 10-100-fold over 3-12 months. A TGAA index more than 0.5 had a positive predictive value (PPV) for histologic confirmation of CD of 96% (22/23). A TGAA index above the usual cutoff for positivity (0.05) had a PPV of only 76% (28/37). CONCLUSIONS In children with TGAA seropositivity, the TGAA level varied over time and a higher titer predicted an abnormal biopsy characteristic of CD. A threshold for biopsy for diagnosis of CD could be set higher for screening-identified cases than for clinically identified cases to decrease the frequency of performing "normal" biopsies.

Abstract
Coeliac disease is a genetically-determined chronic inflammatory intestinal disease induced by an environmental precipitant, gluten. Patients with the disease might have mainly non-gastrointestinal symptoms, and as a result patients present to various medical practitioners. Epidemiological studies have shown that coeliac disease is very common and affects about one in 250 people. The disease is associated with an increased rate of osteoporosis, infertility, autoimmune diseases, and malignant disease, especially lymphomas. The mechanism of the intestinal immune-mediated response is not completely clear, but involves an HLA-DQ2 or HLA-DQ8 restricted T-cell immune reaction in the lamina propria as well as an immune reaction in the intestinal epithelium. An important component of the disease is the intraepithelial lymphocyte that might become clonally expanded in refractory sprue and enteropathy-associated T-cell lymphoma. Study of the mechanism of the immune response in coeliac disease could provide insight into the mechanism of inflammatory and autoimmune responses and lead to innovations in treatment.

Abstract
PURPOSE Intestinal non-Hodgkin's lymphomas are not well characterized. We therefore studied prospectively their clinical features and response to standardized therapy. PATIENTS AND METHODS Fifty-six patients with primary intestinal lymphoma were included in a prospective, nonrandomized multicenter study. Lymphoma resection was recommended and staging was performed according to the Ann Arbor classification. Patients were scheduled to receive six cycles of cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) chemotherapy, and at stages EIII to EIV, they received additional involved-field radiotherapy. Corticosteroids were used in patients who could not receive chemotherapy. RESULTS Thirty-five patients had intestinal T-cell lymphoma (ITCL), 21 patients had intestinal B-cell lymphoma (IBCL; 18 diffuse large-cell lymphomas, two marginal-cell lymphomas, and one follicle-center lymphoma). Thirty-four patients at stages EI to EII (14 ITCL and 20 IBCL) and nine patients at stages EIII to EIV (all ITCL) received chemotherapy. No patient in stages EIII to EIV received radiotherapy, because death occurred in 12 of 14 patients. Two-year cumulative survival in patients with IBCL was 94% (95% CI, 82% to 100%) and higher than in patients with ITCL (28% [95% CI, 13% to 43%]; P <.0001), even when only stages EI to EII were considered (ITCL, 37.5% [95% CI, 16.5% to 58.5%]; P <.0001). IBCL patients compared with ITCL patients were at lower lymphoma stages (P <.01), had higher Karnofsky status (P <.005), had intestinal perforation less often (P <.05), required emergency operation less often (P <.05), received CHOP (P <.05) more often, and reached complete remission (P <.0005) more frequently. CONCLUSION IBCL patients at stages EI and EII respond well to chemotherapy, but the prognosis and treatment of ITCL patients is unsatisfactory.

Abstract
Mature or peripheral T-cell lymphomas are uncommon, accounting for only 10% to 15% of all non-Hodgkin's lymphomas. The classification of these neoplasms has been controversial. In contrast to B-cell lymphomas, cytologic features have not been useful in defining disease entities, and cytologic grade has not helped predict the clinical course. Similarly, many entities of T-cell or natural killer (NK) cell derivation do not have a specific immunophenotype. Clinical features are of major importance in defining T-cell and NK cell neoplasms, and in some cases the clinical syndrome, may be more important than the precise cell of origin. The majority of cytotoxic T-cell and NK cell lymphomas arise in extranodal sites. The expression of cytotoxic molecules in these lymphomas may predispose to apoptosis by tumor cells and normal bystander cells. Three major categories of extranodal T/NK cell tumors are recognized in the World Health Organization (WHO) classification: extranodal NK/T, nasal-type; enteropathy-type; and subcutaneous panniculitis-like. Epstein Barr virus (EBV) is closely linked to nasal NK/T-cell lymphoma, but shows geographic and racial variations in other subtypes. Tumors resembling the prototype of nasal NK/T-cell lymphoma occur in a variety of extranodal sites, and are referred to as nasal-type. Hepatosplenic T-cell lymphoma is a more systemic disease derived from functionally immature cytotoxic cells, usually gammadelta T-cell origin. Cytotoxic T-cell lymphomas of mature gammadelta T-cell origin most often arise in mucocutaneous sites, and may resemble the prototypes of extranodal T/NK cell lymphoma: nasal, enteropathy-associated, and panniculitis-like. Cytotoxic T/NK cell lymphomas occur with increased frequency in the setting of immune suppression, especially following organ transplantation. The nodal T-cell lymphoma most often exhibiting a cytotoxic immunophenotype is anaplastic large cell lymphoma (ALCL). Primary cutaneous ALCL frequently but not invariably expresses cytotoxic molecules. While the majority of extranodal neoplasms are derived from innate immune effector cells of NK cell and T-cell origin (gammadelta greater than alphabeta), most nodal cytotoxic T-cell lymphomas probably belong to the adaptive immune system. Studies of these neoplasms may assist in unraveling the diversity of their normal counterparts.

Abstract
OBJECTIVE Strict lifelong compliance to a gluten-free diet (GFD) minimizes the long-term risk of mortality, especially from lymphoma, in adult celiac disease (CD). Although serum IgA antitransglutaminase (IgA-tTG-ab), like antiendomysium (IgA-EMA) antibodies, are sensitive and specific screening tests for untreated CD, their reliability as predictors of strict compliance to and dietary transgressions from a GFD is not precisely known. We aimed to address this question in consecutively treated adult celiacs. METHODS In a cross-sectional study, 95 non-IgA deficient adult (median age: 41 yr) celiacs on a GFD for at least 1 yr (median: 6 yr) were subjected to 1) a dietician-administered inquiry to pinpoint and quantify the number and levels of transgressions (classified as moderate or large, using as a cutoff value the median gluten amount ingested in the overall noncompliant patients of the series) over the previous 2 months, 2) a search for IgA-tTG-ab and -EMA, and 3) perendoscopic duodenal biopsies. The ability of both antibodies to discriminate celiacs with and without detected transgressions was described using receiver operating characteristic curves and quantified as to sensitivity and specificity, according to the level of transgressions. RESULTS Forty (42%) patients strictly adhered to a GFD, 55 (58%) had committed transgressions, classified as moderate (< or = 18 g of gluten/2 months; median number 6) in 27 and large (>18 g; median number 69) in 28. IgA-tTG-ab and -EMA specificity (proportion of correct recognition of strictly compliant celiacs) was 0.97 and 0.98, respectively, and sensitivity (proportion of correct recognition of overall, moderate, and large levels of transgressions) was 0.52, 0.31, and 0.77, and 0.62, 0.37, and 0.86, respectively. IgA-tTG-ab and -EMA titers were correlated (p < 0.001) to transgression levels (r = 0.560 and R = 0.631, respectively) and one to another (p < 0.001) in the whole patient population (r = 0.834, N = 84) as in the noncompliant (r = 0.915, N = 48) group. Specificity and sensitivity of IgA-tTG-ab and IgA-EMA for recognition of total villous atrophy in patients under a GFD were 0.90 and 0.91, and 0.60 and 0.73, respectively. CONCLUSIONS In adult CD patients on a GFD, IgA-tTG-ab are poor predictors of dietary transgressions. Their negativity is a falsely secure marker of strict diet compliance.

Abstract
BACKGROUND & AIMS Plasma citrulline, a nonprotein amino acid produced by enterocytes, was suggested as a marker of remnant enterocyte mass in patients with short bowel. Our objective was to evaluate citrulline as a marker of severity and extent of villous atrophy in patients without intestinal resection. METHODS Forty-two patients with celiac disease and 10 patients with non-celiac villous atrophy disease were studied by plasma postabsorptive citrulline and biological dosages, biopsies of proximal (duodenojejunal) small bowel and distal ileum (n = 25), or measurement of vitamin B(12) absorption (n = 4). Nine patients were reevaluated after following a gluten-free diet for 1 year. Controls were 51 healthy subjects and 10 severely malnourished patients with anorexia nervosa with no intestinal mucosal abnormalities. RESULTS Plasma citrulline concentration was lower (P < 0.001) in patients with villous atrophy (24 +/- 13 micromol/L) than in healthy subjects (40 +/- 10 micromol/L) and patients with anorexia nervosa (39 +/- 9 micromol/L). Three thresholds were individualized: <10 micromol/L for patients with diffuse total villous atrophy (n = 10), 10-20 micromol/L for patients with proximal-only total villous atrophy (n = 12), and 20-30 micromol/L for patients with partial villous atrophy (n = 10). Plasma citrulline concentration was correlated to the severity and extent of villous atrophy (r = 0.81; P < 0.001) and to albuminemia (r = 0.47; P < 0.01). Receiver operating characteristic curves indicated that plasma citrulline concentration was the best biological variable to predict villous atrophy. Following a 1-year gluten-free diet, plasma citrulline concentration increased in histologically responsive (n = 6) but not in unresponsive (n = 3) patients. CONCLUSIONS In patient villous atrophy diseases, plasma citrulline concentration may prove to be a simple and reliable marker of reduced enterocyte mass.

Abstract
Gene therapy (GT) is still at the 'experimental' stage and some recent setbacks have cooled the potential use of this therapeutic tool even in life-threatening conditions. However, this therapeutic approach has a potential, which is not limited to disease for which we have not other option. There are increasing evidence that GT will be soon used in diseases that are not life threatening. One group of diseases that can benefit from GT is the autoimmune one. Several experimental animal models have indicated the efficacy (proof of principle) of GT. In the present review, we have addressed the possibility that even extremely benign autoimmune-like diseases such as Celiac Disease (CD) might one day profit from this type of therapy. We further point that in conditions such as CD, where the trigger is well known and the pathogenic cascade is relatively well defined, a situation not common in autoimmunity, we can even have a better situation where to explore and use GT to control disease initiation and progression. Once the risks that are still intrinsic to GT will have been reduced the therapeutic options we outline in the present review might not appear too far from reality.

Abstract
BACKGROUND AND AIMS Celiac disease is the most common severe food intolerance in the Western world and is due to gluten ingestion in genetically susceptible children and adults. Intestinal biopsy is the golden standard for evaluation of mucosal damage associated with celiac disease. Gluten-free diet is the key treatment for celiac disease. Data on the long-term control of celiac disease are few and limited to small series of patients. The study reports data on the control of celiac disease and on its correlates in a large cohort of celiac adults during long-term treatment with gluten-free diet. METHODS The study cohort comprises 91 men and 299 women having undergone treatment with a gluten-free diet for at least 2 years and with complete records for visits at the time of diagnosis of celiac disease (baseline). Data collection included gender, age, education, weight, bowel habit, blood hemoglobin, plasma albumin and cholesterol, serum antiendomysium antibodies (EMA), dietary compliance to gluten-free diet (coded as good, low, or very low), and intestinal damage at biopsy (coded as absent, mild, or severe). RESULTS The duration of follow-up was 6.9 +/- 7.5 years (mean +/- SD, range 2-22 years). At follow-up visit, intestinal damage was absent in 170 patients (43.6%), mild in 127 (32.6%), and severe in 93 (23.8%). At follow-up, intestinal damage was significantly associated with dietary compliance, EMA, and plasma albumin (follow-up value and change value from baseline to follow-up). Baseline education significantly predicted dietary compliance and intestinal damage at follow-up. CONCLUSIONS Celiac disease is often poorly controlled in the majority of patients on long-term treatment with a gluten-free diet as demonstrated by intestinal biopsy. Lack of adherence to strict gluten-free diet is the main reason of poorly controlled disease in adults. Laboratory and clinical information have a high positive predictive value and low negative predictive value for intestinal damage on long-term treatment. Dietary compliance as assessed by interview is the best marker of celiac disease control due to low cost, noninvasivity, and strong correlation with intestinal damage.

Abstract
A 79-year-old woman developed collagenous sprue, a rare small intestinal mucosal disorder. Later, extensive T-cell lymphoma was documented, a neoplasm known to complicate celiac disease. Although the precise relationship of collagenous sprue to celiac disease has been debated and remains controversial, the findings here provide additional evidence that collagenous sprue and celiac disease are closely linked. In the past, long-term survival with collagenous sprue may have been compromised due to severe pan-malabsorption. With improved treatment measures, including modern nutritional support, it is likely that there will be an increased opportunity in future for improved appreciation of the complications of collagenous sprue, specifically, lymphoma.

Abstract
Increased levels of interferon-gamma (IFN-gamma) transcripts have previously been found in duodenal biopsy specimens from patients with untreated coeliac disease (CD). Such samples and duodenal control mucosa were therefore studied to locate and phenotype cells spontaneously secreting IFN-gamma. Specimens were collected from consecutively recruited patients with untreated (seven), treated (four) or refractory (three) CD and from five histologically normal controls. Morphological and immunohistochemical examinations were performed, and epithelial and lamina propria cell suspensions were prepared from parallel samples. Unstimulated viable cells secreting IFN-gamma were identified and phenotyped with a new fluorescence-activated cell sorter-based assay, and IFN-gamma messenger RNA (mRNA) was analysed in snap-frozen aliquots of the same suspensions. Untreated CD cases had the highest fraction of IFN-gamma+ cells in the epithelial compartment (median 2.6%, range 1.6-6.2%) and, less strikingly, in the lamina propria compartment (1.6%, range 0.3-3.6%), followed by refractory (1.4%, 1.0-1.9%; and 0.3%, 0.0-1.2%) and treated (0.8%, 0.5-0.9%; and 0.7%, 0.2-1.1%) disease and finally the controls (0.5%, 0.3-0.9%; and 0.2%, 0.1-0.7%). IFN-gamma mRNA data supported these findings. IFN-gamma+ intraepithelial lymphocytes were mostly CD3+ and CD8+, whereas many positive lamina propria cells were CD8-. We conclude that isolated T cells spontaneously secreting IFN-gamma localize preferentially in the epithelium of patients with classical and refractory CD.

Abstract
Celiac disease is a gluten-sensitive enteropathy characterized by villous atrophy that is reversed by gluten withdrawal. A minority of these patients is resistant to a gluten-free diet or, after a period of remission, they experience relapse despite continued adherence to treatment, which is called unclassified sprue or refractory sprue.The prognosis of refractory sprue may be poor: patients may die of severe malabsorption or from the development of an enteropathy-associated T-cell lymphoma. We report a 72-year-old-woman with a diagnosis of refractory sprue who responded well to treatment with corticosteroids and a gluten-free diet.

Abstract
Immunoglobulin A (IgA) deficiency is 10 to 15 times more common in patients with celiac disease (CD) than in healthy subjects. Serological tests have become the preferred methods of diagnosing CD in both symptomatic and asymptomatic patients. However, commercially available serological methods are limited in that they detect only the IgA isotype of antibodies (with the exception of IgG gliadin assays); hence, IgA-deficient patients with CD may yield false-negative serology. Fifteen pediatric patients with CD and 10 IgA-deficient pediatric patients without CD were examined for IgA and IgG antibodies to endomysium, gliadin, and tissue transglutaminase. Twenty-five specimens from patients with IgA deficiency were examined. Fifteen were from patients with CD, and 10 were patients without CD. All 15 IgA-deficient patients with CD were positive for endomysium antibodies of the IgG isotype and for IgG gliadin antibodies. All but one of the IgA-deficient patients with CD were also positive for IgG tissue transglutaminase antibodies. None of the IgA-deficient patients without CD were positive for any of the antibody markers. All the specimens examined were also negative for IgA-specific antibodies to endomysium, gliadin, and tissue transglutaminase. IgG-specific antibody tests for endomysium, gliadin, and tissue transglutaminase are useful for the identification of IgA-deficient patients with CD. IgG antibody tests along with tests routinely being used in clinical laboratories can reliably detect all active patients with CD. In addition, the levels of these CD-specific IgG antibodies could be used to monitor patient dietary compliance.

Abstract
BACKGROUND & AIMS Studies of cancer risk in celiac disease (CD) or dermatitis herpetiformis (DH) indicate increased risks for malignant lymphoma and occasionally other neoplasms, but are characterized by small numbers, lack of systematic cancer assessment, and subjects identified from referral institutions. METHODS By using Swedish population-based inpatient and cancer registry data, we followed-up 12,000 subjects with CD or DH, and evaluated cancer incidence by using standardized incidence ratios (SIR). RESULTS Adults (but not children and adolescents) with CD had an elevated overall risk for cancer (SIR = 1.3) that declined with time and eventually reached unity. Elevated risks were found for malignant lymphomas, small-intestinal, oropharyngeal, esophageal, large intestinal, hepatobiliary, and pancreatic carcinomas. The excess occurrence of malignant lymphomas was confined to adults, decreased with time of follow-up evaluation, and decreased over successive calendar periods. Decreased risks were found for breast cancer. Subjects with DH had a slightly increased overall cancer risk (SIR = 1.2) owing to excesses of malignant lymphoma and leukemia, but no increases of gastrointestinal carcinomas. CONCLUSIONS Albeit increased, the relative risks for lymphomas and gastrointestinal cancers in this study are lower (and declining) than in most previous reports. The overall cancer risk is only moderately increased, and nonelevated during childhood and adolescence.

Abstract
Genetic alterations in enteropathy-type T-cell lymphoma (ETL) are unknown so far. In this series, 38 cases of ETL were analyzed by comparative genomic hybridization (CGH). CGH revealed chromosomal imbalances in 87% of cases analyzed, with recurrent gains of genetic material involving chromosomes 9q (in 58% of cases), 7q (24%), 5q (18%), and 1q (16%). Recurrent losses of genetic material occurred on chromosomes 8p and 13q (24% each), and 9p (18%). In this first systematic genetic study on ETL, chromosomal gains on 9q (minimal overlapping region 9q33-q34) were found to be highly characteristic of ETL. Fluorescence in situ hybridization analysis on four cases of ETL, using a probe for 9q34, indicated frequent and multiple gains of chromosomal material at 9q34 (up to nine signals per case). Among 16 patients with ETL who survived initial disease presentation, patients with more than three chromosomal gains or losses (n = 11) followed a worse clinical course than those with three or less imbalances (n = 5). The observation of similar genetic alterations in ETL and in primary gastric (n = 4) and colonic (n = 1) T-cell lymphoma, not otherwise specified, is suggestive of a genetic relationship of gastrointestinal T-cell lymphomas at either localization.

Abstract
OBJECTIVE Refractory sprue is a rare and severe malabsorptive disorder that mimics celiac disease but is refractory to a gluten-free diet and is without initial evidence of overt lymphoma. Treatment is largely empiric and often ineffective, with steroids and immunosuppression being the mainstream therapeutic options. The aim of this study was to evaluate prospectively the effect of azathioprine on a group of patients diagnosed with refractory sprue. METHODS We studied seven consecutive patients (five women and two men) with a well-defined diagnosis of refractory sprue and a lack of response to oral or parenteral steroids. At diagnosis, five patients had endoscopic evidence of ulcerative jejunitis, and five underwent exploratory laparotomy for exclusion of malignancies. The characteristic monoclonal TCRgamma gene rearrangement was shown in five of six patients studied. Patients were treated for a mean of 11 months (range 8-12 months), and clinical, biochemical, molecular, and histological parameters were reassessed at the end of the trial. The study was a prospective, open-label, non-placebo-controlled study using azathioprine (2 mg/kg/ day) plus oral prednisone (1 mg/kg/day). A gluten-free diet (n = 7) as well as enteral (n = 6) and parenteral nutrition (n = 5) were administered during the trial. RESULTS After treatment, five patients had a complete clinical remission, and biochemical and nutritional parameters were significantly improved. Steroids were tapered after the onset of azathioprine, and no patient was on steroids at the end of the trial. Intestinal histology improved significantly in all cases (normal histology in three cases and minor infiltration in the lamina propria in two). Two patients did not respond to treatment at any time and died in months 10 and 9, of an irreversible ventricular fibrillation and sepsis, respectively. No overt lymphoma was demonstrated during the follow-up. CONCLUSIONS The present study confirms earlier anecdotal reports on the efficacy of azathioprine in refractory sprue, with clear clinical and histological improvement shown in most patients. However, monoclonality persisted after treatment. We consider that a larger number of patients should be evaluated before a definitive recommendation is adopted for use of this drug in refractory sprue.

Abstract
At least one-quarter of the non-Hodgkin's lymphomas arise primarily at extranodal sites. The rising incidence of non-Hodgkin's lymphomas, observed over recent decades, have mainly affected the primary extranodal entities. Survival rates vary among the specific sites of primary extranodal lymphomas. This is due partly to differences in natural history, related mainly to the histological type but also to differences in management strategy which are related to organ-specific problems. Few controlled studies facilitate therapeutic decisions in this setting. This chapter represents a general overview of the available data.

Abstract
Small-intestinal malignancies are rare. Major risk factors for the development of these malignancies include celiac disease, which predisposes to both carcinoma and lymphoma. Crohn's disease patients have an increased risk of the development of adenocarcinoma, as do the inherited polyposis syndromes, FAP, and Peutz-Jehgers syndrome. Each of these conditions provides unique models for the development of malignancy.

Abstract
The development of malignancy, particularly lymphoma, is the most serious complication to affect patients with coeliac disease. Although the association has been known for about 40 years, there are still gaps in our understanding. The prevalence of lymphoma and why only some coeliac patients develop this are not clear but environmental and genetic factors must be at work. Based on data from a large coeliac clinic in Derby, about 55 lymphomas per year would arise in the coeliac population of the United Kingdom, of which half would affect the small bowel. Whether patients with coeliac disease who have atypical or no symptoms at diagnosis, are at the same risk as those who are diagnosed as a result of classical symptoms as was more the case in the past, is not known. Some patients, however do have coeliac disease and lymphoma diagnosed at the same presentation. This consideration has implications for initiating screening programmes to detect coeliac disease and thus offer patients a gluten-free diet early that would help to reduce the risk of lymphoma from developing. In this context, case-finding rather than blanket population screening is to be recommended on present evidence. Research into the role of intraepithelial lymphocytes in the genesis of lymphoma has indicated that non-responsive coeliac disease (refractory sprue) and ulcerative jejunoileitis (ulcerative jejunitis) are part of the lymphoma spectrum. The diagnosis of lymphoma can be difficult and the prognosis, in general, is poor, although with modern chemotherapeutic regimes and surgery in selected cases, long-term survival is possible. The best option is to try and prevent lymphoma from arising by advising all patients to adhere to a strict gluten-free diet. Malignant complications of coeliac disease are uncommon but will continue to challenge clinicians and clinical scientists. Unravelling the mechanisms that contribute to the development of lymphoma and other tumours in coeliac disease may well contribute to a wider understanding of oncogenesis.

Abstract
Celiac disease is a T cell-mediated enteropathy induced by gluten in genetically predisposed individuals. The majority of patients responds to a gluten-free diet but a small number do not. After the exclusion of gluten in the diet, ulcerative jejunititis, and an enteropathy-associated T-cell lymphoma, another treatment modalities, such as systemic steroids and immunosuppressives, may be necessary. This article reports the case of a 47-year-old white woman with immunoglobulin A deficiency. She was diagnosed with celiac disease with subtotal villous atrophy on jejunal biopsy together with positive antiendomysium and antigliadin immunoglobulin G antibodies. Despite close adherence to a gluten-free diet, her weight continued to decrease, she had diarrhea, and her distal duodenal histology showed no improvement. Some improvement in her symptoms was observed with cyclosporine and systemic steroids, but this was not sustained. Recent evidence has suggested that anti-tumor necrosis factor alpha antibodies have a role in the amelioration of an animal model of villous atrophy, and after careful consideration, she was treated with infliximab. There was a dramatic improvement in her weight, symptoms, and distal duodenal histology. The response has been maintained for 18 months while on azathioprine therapy. It is concluded that infliximab is an effective treatment that may be considered in a small number of patients with refractory celiac disease, resistant to other therapy.

Abstract
Gliadin specific T cells in the small intestines of coeliac disease patients use the disease associated human leukocyte antigen-DQ2 molecules in their antigen recognition. In an exciting interplay with tissue transglutaminase, the immune system recognises modified gliadin peptides and mounts a phlogistic response. Moreover, the role for autoimmune phenomena and the mechanism of breaking of immunological tolerance remain elusive.

Abstract
Increased awareness of non-classical presentations and more reliable screening tests have led to higher detection rates for coeliac disease in elderly adults. Clinical presentations are influenced largely by the long-standing course of the subclinical disease before diagnosis. In the majority of elderly patients, weight loss, diarrhoea and iron deficiency anaemia are present. With a delay in diagnosis, there are increased risks of associated autoimmune diseases, of neoplasms (mostly small bowel lymphoma) and of metabolic bone diseases. Thyroid disease is the most common autoimmune disease. Lymphoma may be the initial presentation or may complicate the clinical course of well established coeliac disease. Osteopenia is very common at presentation, can be clinically severe and require specific therapy in addition to the gluten-free diet. The high risk of complications in elderly patients with coeliac disease warrants a systematic approach in their investigation and management.

Abstract
Graft-versus-host disease (GVHD) can be acute or chronic. The pathogenesis of chronic GVHD is unclear. Chronic GVHD affects mainly skin, liver and digestive tract. Intestinal involvement is uncommon and histological features are poorly described. We report here the clinical, histological and immunohistochemical features of chronic GVHD with intestinal involvement. Intestinal biopsies from children with chronic GVHD (n=17) were compared to control children (n=21: 10 non-transplant cases, four non-GVHD transplant cases, seven acute GVHD). We evaluated clinical outcome, histological features and characterized immunohistochemically the immune cells involved locally. Chronic GVHD with intestinal involvement was usually multisystemic (88.2%) and preceded by acute GVHD in 88.2% of cases. The outcome was severe with complete recovery in only 58.8% of cases, and death related to chronic GVHD in 17.6% of cases. Histological features were characterized by (1) villous atrophy and (2) glandular lesions, mainly apoptotic with variable intensity and (3) lamina propria infiltrate with cytotoxic T lymphocytes (CD3+, CD8+, TiA1+, granzyme B-) which were significantly (P<0.001) increased compared to non-GVHD transplant and non-transplant controls. Therefore in chronic intestinal GVHD, the apoptotic process could be related to cytotoxic T lymphocytes.

Abstract
Refractory coeliac disease (RCD) is a rare diagnosis made after the exclusion of any disorder mimicking CD and after initial or subsequent failure of a strict gluten-free diet (GFD) to restore normal intestinal architecture. In the past, treatments such as steroids, cyclosporin and azathioprine have been tried, but literature on this subject consists mainly of case reports. Interleukin-10 (IL-10) may be beneficial in RCD because of its inhibitory effect on T-lymphocyte- and monocyte-driven immune responses. We performed a pilot, non-randomized, open label study to evaluate recombinant human IL-10 in RCD. IL-10 (8 mcg/kg) was administered subcutaneously, three times a week for 3 months in 10 RCD patients. Small bowel biopsies were taken at T = 0, T = 3 months and T = 9 months. The mucosal histopathology at 3 months was the primary end point for evaluation of efficacy. Evaluations of clinical features, malabsorption parameters and safety were made prior to, during and after treatment. Before treatment, all RCD patients had partial to total villous atrophy (Marsh III ABC). Two patients dropped out of the study: one because of headaches, the other because of thrombocytopenia. In the remaining eight patients, after 3 months of IL-10 treatment histology was unchanged in five patients, improved in two patients and deteriorated in one patient. Disappearance of villous atrophy was seen in only one patient. Three patients reported a clinical response, i.e. relief of fatigue, abdominal complaints and diarrhoea. After stopping IL-10 treatment the symptoms recurred. The laboratory parameters remained the same during treatment and in follow-up. In conclusion, in our study group of 10 RCD patients, IL-10 in the given dosage was not overall effective in our study group of RCD patients. Two dropped out because of side effects and in only one patient did we see a normalization of villous architecture.

Abstract
Small intestinal neoplasms are uncommonly encountered in clinical practice. They may occur sporadically, in association with genetic diseases (e.g., familial adenomatous polyposis coli or Peutz-Jeghers syndrome), or in association with chronic intestinal inflammatory disorders (e.g., Crohn's disease or celiac sprue). Benign small intestinal tumors (e.g., leiomyoma, lipoma, hamartoma, or desmoid tumor) usually are asymptomatic but may present with intussusception. Primary malignancies of the small intestine-including adenocarcinoma, leiomyosarcoma, carcinoid, and lymphoma-may present with intestinal obstruction, jaundice, bleeding, or pain. Extraintestinal neoplasms may involve the intestine via contiguous spread or peritoneal metastasis. Hematogenous metastases to the intestine from an extraintestinal primary are unusual and are most typical of melanoma. Because the small intestine is relatively inaccessible to routine endoscopy, diagnosis of small intestinal neoplasms is often delayed for months after onset of symptoms. When the diagnosis is suspected, enteroclysis is the most useful imaging study. Small bowel endoscopy (enteroscopy) is increasingly widely available and may permit earlier, nonoperative diagnosis.

Abstract
OBJECTIVE The diagnosis of coeliac disease (CD) is based on the responsiveness of the enteropathy to a gluten-free diet (GFD). This implies that terms such as 'non-responsive CD' and 'refractory CD' are almost paradoxical. In spite of this, these terms are commonly used in the literature, often with different and confusing meanings. METHODS On the basis of both a review of the literature and our clinical experience, we propose the following classification. A condition characterized by a refractory enteropathy, not due to lymphoma, ulcerative jejunoileitis or collagenous sprue, but in which gluten sensitivity has been shown previously or could be shown while the patients were on an immunosuppressive therapy should be indicated as refractory CD. Those patients in whom gluten sensitivity can be excluded should be considered to be affected by non-coeliac refractory sprue. Finally, patients in whom the presence of CD cannot be either confirmed or excluded should be considered to be affected by undefined sprue. RESULTS Twenty-four certain refractory patients are described in the literature. The data suggest a diagnosis of refractory CD in 13 patients, non-coeliac refractory sprue in three patients, and undefined sprue in eight patients. CONCLUSIONS We define refractory CD as a form of CD that no longer responds to a GFD. Non-coeliac refractory sprue is a condition unrelated to CD. It could be either an independent condition or a common end point of different enteropathies.

Abstract
Gastrointestinal lymphomas comprise a group of distinct clinicopathological entities. Differences in lifestyle and environmental factors between countries could account for the variety in the distribution of the main subtypes: low-grade B-cell lymphomas of the mucosa-associated lymphoid tissue type, alpha-chain disease and enteropathy (coeliac disease)-associated T-cell lymphoma (EATL). The possibility of preventing these lymphomas implies a knowledge of their natural history together with an identification of potential predisposing factors. The development of the lymphoid hyperplasia and subsequently low-grade lymphoma with the possibility of high-grade transformation is a multifactorial process involving both antigenic and host-related factors. The pathogenic role of Helicobacter pylori and gluten has been demonstrated in gastric lymphoma and enteropathy-associated T-cell lymphoma respectively, while environmental factors, especially non-specific bacterial ones, may play a major role in the pathogenesis of alpha-chain disease. The most difficult task in preventing these lymphomas is the recognition of early lesions likely to regress after the removal of the exogenous stimulus.

Abstract
Celiac disease is more prevalent than it was previously thought to be, and screening of selected population groups may reveal many new cases. Tissue transglutaminase appears to have a significant role in the degradation of gliadin and antigen production. Specific gliadin epitopes have been defined using T-cell responses. Bone disease is a significant problem for patients with celiac disease but management guidelines are being developed. Refractory sprue (nonresponsive celiac disease) appears to be a manifestation of enteropathy-associated T-cell lymphoma in most cases.

Abstract
Celiac disease (CD) is a syndrome characterized by damage of the small intestinal mucosa caused by the gliadin fraction of wheat gluten and similar alcohol-soluble proteins (prolamines) of barley and rye in genetically susceptible subjects. The presence of gluten in these subjects leads to self-perpetuating mucosal damage, whereas elimination of gluten results in full mucosal recovery. The clinical manifestations of CD are protean in nature and vary markedly with the age of the patient, the duration and extent of disease, and the presence of extraintestinal pathologic conditions. In addition to the classical gastrointestinal form, a variety of other clinical manifestations of the disease have been described, including atypical and asymptomatic forms. Therefore, diagnosis of CD is extremely challenging and relies on a sensitive and specific algorithm that allows the identification of different manifestations of the disease. Serologic tests developed in the last decade provide a noninvasive tool to screen both individuals at risk for the disease and the general population. However, the current gold standard for the diagnosis of CD remains histologic confirmation of the intestinal damage in serologically positive individuals. The keystone treatment of CD patients is a lifelong elimination diet in which food products containing gluten are avoided.
