Abstract: Background Whether vedolizumab may be effective as a treatment for primary sclerosing cholangitis [PSC] in patients with inflammatory bowel disease [IBD] remains controversial. Methods We performed a retrospective observational study of consecutive patients with IBD and PSC, treated with vedolizumab for at least 30 weeks in 22 centres of GETAID from January 2015 to June 2016. The outcomes included a decrease in the serum alkaline phosphatase [ALP] concentration of at least 50% from baseline to Week 30 or 54, a change in any serum liver enzymes concentrations, and an assessment of the efficacy and safety of vedolizumab in IBD. Results Among 75 patients with active IBD and PSC treated with vedolizumab, 21 patients discontinued vedolizumab before Week 30 [due to lack of efficacy in 19 and malignancy in two patients]. In the remaining 54 patients, a decrease in the serum ALP concentration of at least 50% from baseline to Weeks 30 and 54 was observed in four [7%] and four [11%] patients, respectively. No significant change was observed in serum liver enzyme concentrations at week 30 or 54. After a median follow-up period of 19.4 [14.0–29.9] months, nine cases of digestive neoplasia [colorectal neoplasia in seven and cholangiocarcinoma in two] were reported. Conclusions In patients with IBD and PSC, vedolizumab did not improve serum liver enzyme concentrations at week 30 or 54. Nine cases of digestive cancer occurred during the follow-up period, confirming the need for a tight surveillance programme in this population.

Abstract: Cohort studies have described the short-term effectiveness and safety of vedolizumab in treating patients with Crohn's disease (CD) and ulcerative colitis (UC), but data beyond 1 year are lacking.To assess the effectiveness and safety of vedolizumab after 162 weeks in patients with UC and CD.Between June and December 2014, 294 patients including 173 patients with CD and 121 with UC were treated with vedolizumab induction therapy. Among them, 149 continued to be treated with vedolizumab beyond week 54 (78 patients with CD and 71 with UC). Disease activity was assessed using the Harvey-Bradshaw Index for CD and the partial Mayo Clinic score for UC. The primary outcome was steroid-free clinical remission at week 162, computed for the whole population included at week 0.Steroid-free clinical remission rates at week 162 were 19.9% and 36.1% in patients with CD and UC respectively. Vedolizumab dose optimisation to 300 mg every 4 weeks instead of 300 mg every 8 weeks was at investigator's discretion and occurred in 58.7% and 52.1% of patients with CD and UC respectively. The 1-, 2- and 3-year persistence rates of vedolizumab were 48.5%, 31.4% and 26.3% respectively, in patients with CD and 61.0%, 49.9% and 42.9% respectively, in patients with UC. No new safety signal was identified.Vedolizumab is able to maintain steroid-free clinical remission in patients with UC and CD up to week 162. Loss of response resulting in discontinuation of vedolizumab occurred in 10% of patients per year.

Abstract: Background & Aims Little is known about long-term outcomes of patients with Crohn's disease (CD) after infliximab withdrawal. We aimed to describe the long-term outcomes of patients with CD in clinical remission after infliximab treatment was withdrawn. Methods We performed a retrospective analysis of data from the 115 patients included in the infliximab discontinuation in patients with CD in stable remission on combined therapy with antimetabolites (STORI) study, performed at 20 centers in France and Belgium from March 2006 through December 2009. The STORI cohort was a prospective analysis of risk and factors associated with relapse following withdrawal of maintenance therapy with infliximab, maintained on antimetabolites, while in clinical remission. We collected data from the end of the study until the last available follow-up examination on patient surgeries, new complex perianal lesions (indicating major complications), and need for and outcomes of restarting therapy with infliximab or another biologic agent. The de-escalation strategy was considered to have failed when a major complication or infliximab restart failure occurred. Results Of the 115 patients initially included, data from 102 patients (from 19 of the 20 study centers) were included in the final analysis. The median follow-up time was 7 years. Twenty-one percent of the patients did not restart treatment with infliximab or another biologic agent and did not have a major complication 7 years after infliximab withdrawal (95% CI, 13.1–30.3). Among patients who restarted infliximab, treatment failed for 30.1% 6 years after restarting (95% CI, 18.5–42.5). Overall, at 7 years after stopping infliximab therapy, major complications occurred in 18.5% of patients (95% CI, 10.2–26.8) whereas 70.2% of patients had no failure of the de-escalation strategy (95% CI, 60.2–80.1). Factors independently associated with major complications were upper-gastrointestinal location of disease, white blood cell count ≥ 5.0 × 109/L, and hemoglobin level ≤12.5 g/dL at the time of infliximab withdrawal. Patients with at least 2 of these factors had a more than 40% risk of major complication in the 7 years following infliximab withdrawal. Conclusions In a long-term follow-up of the STORI cohort (7 years) one fifth of the patients did not restart infliximab or another biologic agent and did not develop major complications. Seventy percent of patients had no failure of the de-escalation strategy (no major complication and no failure of infliximab restart).

Abstract: Aims: Steadily the clinicians of our team in inflammatory bowel disease encounter ulcerative colitis patients that develop deep ulcers during their treatment. Currently, these practitioners are only equipped with their grade of expertise in inflammatory domains to decide what new therapy maybe use in such cases. Encouraged by the limited knowledge of this frequent pathology, we seek to determine the molecular conditions underlying the recurrent formation of deep ulcerations in certain group of patients. Method: The goal of this strategy is to expose differences between groups of patients based on similarities computed by random walk graph kernels and performing functional inference on those differences. Results: We apply the methodology to a cohort of eleven miRNA microarrays of ulcerative colitis patients. Our results showed how the group of ulcerative colitis patients with presence of deep ulcers is topologically more similar (0.35) than ulcerative colitis patients (0.18) to control. Such topological constraint drove functional inference to complete the information that clinicians need. Conclusions: Our analyses reveal highly interpretable in the guidance of practitioners to eventually correct initial therapies of ulcerative colitis patients that develop deep ulcers. The methodology can provide them with useful molecular hypotheses necessaries prior to make any decision on the newest course of the treatment.

Abstract: Backgrounds and Aims: The effect of cigarette smoking [CS] is ambivalent since smoking improves ulcerative colitis [UC] while it worsens Crohn’s disease [CD]. Although this clinical relationship between inflammatory bowel disease [IBD] and tobacco is well established, only a few experimental works have investigated the effect of smoking on the colonic barrier homeostasis focusing on xenobiotic detoxification genes. Methods: A comprehensive and integrated comparative analysis of the global xenobiotic detoxification capacity of the normal colonic mucosa of healthy smokers [ n = 8] and non-smokers [ n = 9] versus the non-affected colonic mucosa of UC patients [ n = 19] was performed by quantitative real-time polymerase chain reaction [qRT PCR]. The detoxification gene expression profile was analysed in CD patients [ n = 18], in smoking UC patients [ n = 5], and in biopsies from non-smoking UC patients cultured or not with cigarette smoke extract [ n = 8]. Results: Of the 244 detoxification genes investigated, 65 were dysregulated in UC patients in comparison with healthy controls or CD patients. The expression of ≥ 45/65 genes was inversed by CS in biopsies of smoking UC patients in remission and in colonic explants of UC patients exposed to cigarette smoke extract. We devised a network-based data analysis approach for differentially assessing changes in genetic interactions, allowing identification of unexpected regulatory detoxification genes that may play a major role in the beneficial effect of smoking on UC. Conclusions: Non-inflamed colonic mucosa in UC is characterised by a specifically altered detoxification gene network, which is partially restored by tobacco. These mucosal signatures could be useful for developing new therapeutic strategies and biomarkers of drug response in UC.

Abstract: BackgroundMEN1, which is secondary to the mutation of the MEN1 gene, is a rare autosomal-dominant disease that predisposes mutation carriers to endocrine tumors. Most studies demonstrated the absence of direct genotype-phenotype correlations. The existence of a higher risk of death in the Groupe d'étude des Tumeurs Endocrines-cohort associated with a mutation in the JunD interacting domain suggests heterogeneity across families in disease expressivity. This study aims to assess the existence of modifying genetic factors by estimating the intrafamilial correlations and heritability of the six main tumor types in MEN1.MethodsThe study included 797 patients from 265 kindred and studied seven phenotypic criteria: parathyroid and pancreatic neuroendocrine tumors (NETs) and pituitary, adrenal, bronchial, and thymic (thNET) tumors and the presence of metastasis. Intrafamilial correlations and heritability estimates were calculated from family tree data using specific validated statistical analysis software.ResultsIntrafamilial correlations were significant and decreased along parental degrees distance for pituitary, adrenal and thNETs. The heritability of these three tumor types was consistently strong and significant with 64% (s.e.m.=0.13; Ps.e.m.=0.21; Ps.e.m.=0.41; P=0.006) for thNETs.ConclusionThe present study shows the existence of modifying genetic factors for thymus, adrenal, and pituitary MEN1 tumor types. The identification of at-risk subgroups of individuals within cohorts is the first step toward personalization of care. Next generation sequencing on this subset of tumors will help identify the molecular basis of MEN1 variable genetic expressivity.

Abstract: International audience; : OBJECTIVES:Although anti-tumor necrosis factor (TNF) therapy is the treatment of choice for perianal fistulizing Crohn's disease (CD), the efficacy and safety of anti-TNF therapy in enterocutaneous fistula (ECF) remains unclear.METHODS:Between January 2008 and December 2009, we retrospectively reviewed the outcomes of all CD patients with ECF (excluding perianal fistula) treated with anti-TNF therapy followed up in Groupe d'Etude Thérapeutique des Affections Inflammatoires du tube Digestif (GETAID) centers. ECF closure and tolerance of anti-TNF therapy were studied using univariate and multivariate analyses.RESULTS:Forty-eight patients (twenty-six women; median age 34.6 (interquartile range=25.0-45.5) years) were included in this study. The median follow-up period was 3.0 (2.0-6.6) years. The fistula was located in the small bowel (n=38), duodenum (n=1), and colon (n=9). The fistula has been developed in ileocolonic anastomosis in 17 (35%) cases. Sixteen patients (33%) had complex fistulas with multiple tracts and eleven patients (23%) had a high ECF output (if wearing an ostomy bag). Complete ECF closure was achieved in 16 (33%) patients, of whom eight relapsed during the follow-up period. In multivariate analysis, complete ECF closure was associated with the absence of multiple ECF tracts and associated stenosis. An abdominal abscess developed in 15 (31%) patients. ECF resection was needed in 26 (54%) patients. One patient died after surgery owing to abdominal sepsis.CONCLUSIONS:In CD patients with ECF, anti-TNF therapy may be effective in up to one-third of patients, especially in the absence of stenosis and complex fistula. A careful selection of patients is mandatory to prevent treatment failure and improves the safety.Am J Gastroenterol advance online publication, 5 August 2014; doi:10.1038/ajg.2014.183.

Abstract: Background: Liver surgery is the best treatment for endocrine liver metastases, but it is often impossible due to diffuse disease. Systemic chemotherapy is poorly effective. Hepatic arterial embolization (HAE) and chemoembolization (HACE) have shown efficacy but have never been compared. Patients and Methods: Patients with progressive unresectable liver metastases from midgut endocrine tumors were randomly assigned to receive HAE or HACE (two procedures at 3-month interval). The primary end point was the 2-year progression-free survival (PFS) rate. Secondary end points were response rates, overall survival, and safety. Results: Twelve patients were assigned to receive HACE and 14 to receive HAE. The patient characteristics were well matched across the treatment arms. The 2-year PFS rates were 38 and 44% in the HACE and HAE arms, respectively (p = 0.90). Age, gender, previous resection of the primary tumor or liver metastases, extent of liver involvement, and concomitant treatment with somatostatin analogues were not associated with changes in PFS, whereas elevated baseline urinary 5-HIAA and serum chromogranin A levels were associated with shorter PFS. The 2-year overall survival rates were 80 and 100% in the HACE and HAE arms, respectively (p = 0.16). The disease control rate on CT scan was 95%. Grade 3 toxicity occurred in 19% of patients, with no treatment-related deaths and no differences in the treatment arms. Conclusion: HACE and HAE are safe and permit tumor control in 95% of patients with progressive liver metastases from midgut endocrine tumors. The 2-year PFS was not higher among patients receiving HACE, not favoring the hypothesis of an additive efficacy of arterial chemotherapy or embolization alone.

Abstract: ContextMultiple endocrine neoplasia type 1 (MEN1) disease is an autosomal dominant syndrome that is believed to equally affect men and women. This assumption has never been confirmed.ObjectiveThe aims of this study were to evaluate the impact of gender on the prevalence of MEN1 lesions, on their lifetime probability of occurrence, and on the diagnosis of MEN1.DesignData regarding a study of 734 cases of MEN1 from the multicenter ‘Groupe d'étude des Tumeurs Endocrines’ were analyzed.ResultsThere were 57.8% females. The prevalence and probability of pancreatic tumors were higher in males than in females (P=0.06, P=0.0004). This difference was due to gastrinomas. The prevalence and probability of developing pituitary tumors were significantly greater in females (PPP=0.02). In the case of pituitary tumor, the proportion of patients diagnosed with MEN1 at the time of the first lesion was lower in women (44.2%) than in men (67.3%).ConclusionThe phenotype expression of the MEN1 disease gene was different in males and females. In female patients, the possibility of MEN1 is not sufficiently taken into account. Any patient presenting a lesion that belongs to the MEN1 spectrum, such as a pituitary tumor, should be closely questioned about their family history and should be tested for hypercalcemia.

Abstract: International audience; BACKGROUND & AIMS: Psoriasiform and eczematiform lesions are associated with anti-tumor necrosis factor (TNF)-α therapies. We assessed clinical characteristics, risk factors, and outcomes of skin disease in patients with inflammatory bowel diseases that presented with psoriasiform and eczematiform lesions induced by anti-TNF-α agents. METHODS: We studied 85 patients (69 with Crohn's disease, 15 with ulcerative colitis, and 1 with indeterminate colitis; 62 women) with inflammatory skin lesions (62 psoriasiform and 23 eczematiform lesions). RESULTS: Twenty-four patients had a history of inflammatory skin lesions and 15 had a familial history of inflammatory skin disease. Locations of eczematiform lesions varied whereas scalp and flexural varieties were mostly psoriasiform. Skin lesions emerged but inflammatory bowel disease was quiescent in 69 patients following treatment with any type of anti-TNF-α agent (60 with infliximab, 20 with adalimumab, and 5 with certolizumab). Topical therapy resulted in partial or total remission in 41 patients. Patients with psoriasiform lesions that were resistant to topical therapy and that changed anti-TNF-α therapies once or twice developed recurring lesions. Overall, uncontrolled skin lesions caused 29 patients to stop taking TNF-α inhibitors. CONCLUSIONS: Inflammatory skin lesions following therapy with TNF-α inhibitors occurred most frequently among women and patients with a personal or familial history of inflammatory skin disease; lesions did not correlate with intestinal disease activity. Recurring and intense skin lesions caused 34% of patients in this study to discontinue use of anti-TNF-α agents.

Abstract: International audience; OBJECTIVES: The enteropathy associated with common variable immunodeficiency (CVID) is poorly characterized, and its possible relationships with well-defined causes of enteropathy, such as celiac sprue (CS), remain debated. We aimed to assess the clinical and histopathological features of the enteropathy associated with CVID. METHODS: The medical files of 50 CVID patients with gastrointestinal symptoms were analyzed retrospectively. Histological, phenotypic, and molecular analysis of intestinal endoscopic specimens was centrally performed. RESULTS: Chronic diarrhea was the most frequent gastrointestinal symptom (92%), and biological evidence of malabsorption was observed in 54% of patients. Chronic gastritis associated or not with pernicious anemia and microscopic colitis were the most frequently observed histopathological features in gastric and colonic mucosa, respectively. Small-bowel biopsies available in 41 patients showed moderate increase in intestinal intraepithelial lymphocytes in 31 patients (75.6%) and villous atrophy in 21 patients (51%). Distinctive features from CS were a profound depletion in plasma cells and follicular lymphoid hyperplasia. Presence of peripheral blood CD8+ hyperlymphocytosis was predictive of intestinal intraepithelial hyperlymphocytosis. Intravenous (i.v.) immunoglobulin (Ig) therapy had no effect on enteropathy-related symptoms. Gluten-free diet improved only two out of 12 patients with villous atrophy, whereas all patients (7/7) responded to steroid therapy. CONCLUSIONS: Several distinctive features differentiate CVID enteropathy from other causes of enteropathy including CS. Replacement i.v. Ig therapy is insufficient to improve gastrointestinal symptoms. Steroids are effective in reducing inflammation and restoring mucosal architecture.

Abstract: International audience; BACKGROUND: Reports of an increased risk of lymphoproliferative disorders in patients receiving thiopurines for inflammatory bowel disease are controversial. We assessed this risk in a prospective observational cohort study. METHODS: 19,486 patients with inflammatory bowel disease, of whom 11,759 (60.3%) had Crohn's disease and 7727 (39.7%) had ulcerative colitis or unclassified inflammatory bowel disease, were enrolled in a nationwide French cohort by 680 gastroenterologists, who reported details of immunosuppressive therapy during the observation period, cases of cancer, and deaths. The risk of lymphoproliferative disorder was assessed according to thiopurine exposure. Median follow-up was 35 months (IQR 29-40). FINDINGS: At baseline, 5867 (30.1%) of patients were receiving, 2809 (14.4%) had discontinued, and 10,810 (55.5%) had never received thiopurines. 23 new cases of lymphoproliferative disorder were diagnosed, consisting of one case of Hodgkin's lymphoma and 22 cases of non-Hodgkin lymphoproliferative disorder. The incidence rates of lymphoproliferative disorder were 0.90 per 1000 (95% CI 0.50-1.49) patient-years in those receiving, 0.20/1000 (0.02-0.72) patient-years in those who had discontinued, and 0.26/1000 (0.10-0.57) patient-years in those who had never received thiopurines (p=0.0054). The multivariate-adjusted hazard ratio of lymphoproliferative disorder between patients receiving thiopurines and those who had never received the drugs was 5.28 (2.01-13.9, p=0.0007). Most cases associated with thiopurine exposure matched the pathological range of post-transplant disease. INTERPRETATION: Patients receiving thiopurines for inflammatory bowel disease have an increased risk of developing lymphoproliferative disorders.

Abstract: International audience; Celiac disease (CD) is an enteropathy resulting from an abnormal immune response to gluten-derived peptides in genetically susceptible individuals. This immune response is initiated by intestinal transport of intact peptide 31-49 (p31-49) and 33-mer gliadin peptides through an unknown mechanism. We show that the transferrin receptor CD71 is responsible for apical to basal retrotranscytosis of gliadin peptides, a process during which p31-49 and 33-mer peptides are protected from degradation. In patients with active CD, CD71 is overexpressed in the intestinal epithelium and colocalizes with immunoglobulin (Ig) A. Intestinal transport of intact p31-49 and 33-mer peptides was blocked by polymeric and secretory IgA (SIgA) and by soluble CD71 receptors, pointing to a role of SIgA-gliadin complexes in this abnormal intestinal transport. This retrotranscytosis of SIgA-gliadin complexes may promote the entry of harmful gliadin peptides into the intestinal mucosa, thereby triggering an immune response and perpetuating intestinal inflammation. Our findings strongly implicate CD71 in the pathogenesis of CD.

Abstract: BACKGROUND: Ulcerative Colitis (UC) and Crohn's Disease (CD) are two chronic Inflammatory Bowel Diseases (IBD) affecting the intestinal mucosa. Current understanding of IBD pathogenesis points out the interplay of genetic events and environmental cues in the dysregulated immune response. We hypothesized that dysregulated microRNA (miRNA) expression may contribute to IBD pathogenesis. miRNAs are small, non-coding RNAs which prevent protein synthesis through translational suppression or mRNAs degradation, and regulate several physiological processes. METHODOLOGY/FINDINGS: Expression of mature miRNAs was studied by Q-PCR in inactive colonic mucosa of patients with UC (8), CD (8) and expressed relative to that observed in healthy controls (10). Only miRNAs with highly altered expression (>5 or 100 -fold and 0.05-0.19 -fold for over- and under- expression, respectively; 0.001

Abstract: Objective: Objective structured clinical examinations (OSCE) are one of the main modalities of skills' assessment of medical students. We aimed to evaluate the educational value of the participation of third-year medical students in OSCE as standardized patients., Methods: We conducted a pilot OSCE session where third-year students participated in sixth-year students' OSCE as standardized patients (cases). Their scores in their own subsequent OSCE exams were compared with third-year students who had not participated (controls). Students' perceptions (stress, preparedness, ease) regarding their OSCE were compared with self-administered questionnaires., Results: A total of 42 students were included (9 cases and 33 controls). Median [IQR] overall score (out of 20 points) obtained by the cases was 17 [16.3-18] versus 14.5 [12.7-16.3] for controls ( p < 0.001). Students' perception of their evaluation (difficulty, stress, communication) was not significantly different between cases and controls. Most cases agreed that their participation was beneficial in reducing their stress (67%), increasing their preparedness (78%) and improving their communication skills (100%). All cases agreed that this participation should be offered more widely., Conclusion: Students' participation in OSCE as standardized patients led to better performance on their own OSCE and were considered beneficial. This approach could be more broadly generalized to improve student performance.

Abstract: Objective: Despite the continuing controversy of covered stents (CS) vs bare metal stents, the use of CS in mesenteric occlusive disease (MOD) has been recommended by expert centers. The aim of this study was to report midterm results with CS of the superior mesenteric artery., Methods: Between January 2014 and October 2019, patients with MOD with a severe atheromatous stenosis or occlusion of the superior mesenteric artery treated by mesenteric CS were included. Clinical presentation included both acute mesenteric ischemia (AMI), chronic mesenteric ischemia, and asymptomatic patients planned for major surgery. Demographics, procedure details, and follow-up data were prospectively collected and retrospectively reviewed. Study end points included primary patency, primary assisted patency, and secondary patency., Results: During the study period, 86 patients (mean age, 70 ± 9 years; 57% males) were included. Clinical presentation was AMI (n = 42 [49%]), chronic mesenteric ischemia (n = 31 [36%]), and asymptomatic (n = 13 [15%]). The technical success rate was 97%. A total of 96 stents were implanted, including 86 proximal CS (Advanta V12, n = 73; Lifestream, n = 13). The mean length and mean diameter of the CS were 31.5 ± 6.3 mm and 6.9 ± 0.5 mm, respectively. Additional distal bare metal stents were used in 10 patients (12%) to overcome a kinking (n = 9) or a dissection (n = 1) downstream of the CS. All postoperative deaths occurred in patients with AMI (n = 11, 13%). During a median follow-up of 15.6 months (95% confidence interval [CI], 15.6 ± 3.6 months), 12 patients (14%) underwent reinterventions for either stent misplacement (n = 3), stent recoil (n = 3), stent thrombosis (n = 2), de novo stenosis at the distal edge of the CS (n = 2), or gastric ischemia (n = 1). At 1 year, overall the primary patency, primary assisted patency, and secondary patency rates were 83% (95% CI, 83% ± 9%), 99% (95% CI, 99% ± 3%), and 99% (95% CI, 99% ± 3%), respectively. At 2 years, the overall primary patency, primary assisted patency, and secondary patency rates were 76% (95% CI, 76% ± 13%), 95% (95% CI, 95% ± 8%) and 95% (95% CI, 95% ± 8%), respectively., Conclusions: Mesenteric CS provide very satisfactory midterm results in patients with MOD, with an excellent primary assisted patency rate at 2 years, at the price of a significant reintervention rate., (Copyright © 2021 Society for Vascular Surgery.

Abstract: Background: Spontaneous and isolated dissection of the superior mesenteric artery (SIDSMA) is a rare pathology, and the treatment of symptomatic forms is not consensual. The objective of this study was to analyze the management of a series of patients presenting a symptomatic SIDSMA within a structure taking care of intestinal vascular emergencies., Methods: From January 2010 to January 2014, the patients presenting a symptomatic SIDSMA were included retrospectively. The clinical and radiologic data as well as the treatment and the follow-up were analyzed., Results: Nine patients were included. Among them, 2 patients presenting with acute mesenteric ischemia were revascularized surgically in emergency, and 1 patient presenting a rupture of a superior mesenteric artery aneurysm had an arteriography followed by medical care. The 6 other patients received medical treatment. Among these, 2 patients developed mesenteric angina requiring surgical revascularization during the follow-up., Conclusions: The revascularization of spontaneous and isolated dissections of the superior mesenteric artery is indicated in the cases complicated with acute mesenteric ischemia, aneurysmal rupture, or in the event of appearance of mesenteric angina or aneurysmal evolution. It should also be discussed in the event of failure of the medical treatment., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Abstract: Although malnutrition is known to be frequent in cancer patients, it has not been described in a selected population of patients with gastrointestinal malignancies under chemotherapy only. Physician judgment about malnutrition and risk factors for malnutrition were also evaluated. All consecutive in- and outpatients of 11 centers were prospectively enrolled in a cross-sectional 14-day period study and classified according to the French health recommendations [Haute Autorité de Santé (HAS)]. Among 313 patients enrolled in 11 centers (mean age = 63 yr; range = 21-93; 67% male) mainly with colorectal (58%), pancreatic (15%), gastric (11%), and hepatobiliary (10%) primary tumors, the prevalence of malnutrition was 52%. Moderate and severe malnutrition was present in 27% and 25% of cases, respectively. Physicians considered it in 36% and 6% of cases, respectively, thereby misclassifying 134 patients (43%). The agreement between the HAS definition and the physicians' judgment was very low (κ = 0.30). Most of the patients who were identified as severely malnourished received no nutritional support. Performance status and pancreatic and gastric cancers were independently associated with malnutrition. Malnutrition levels are high, around 50%, unequally distributed according to the primitive tumor. It is still underestimated by physicians. Weight loss remains a clinically relevant, simple, and reliable marker of malnutrition.

Abstract: The two major inflammatory bowel diseases, Crohn's disease (CD) and ulcerative colitis (UC), represent clinicopathologic entities that traditionally have been diagnosed on the basis of a combination of clinical, radiologic, endoscopic, and histologic features. The presence of an inflammatory syndrome associated with typical clinical manifestations must lead to perform endoscopic examinations. Ileocolonoscopy plays an integral role in establishing the diagnosis, excluding other etiologies, distinguishing Crohn's disease from ulcerative colitis, defining the patterns, extent, and activity of mucosal inflammation, and obtaining mucosal tissue for histologic evaluation of inflammatory bowel disease. Small bowel follow through is still a major examination. However, the role of CT and MRI (using enteroclysis) in the imaging of inflammatory bowel disease has also increased in importance. Capsule endoscopy could be a valuable diagnostic tool in patients with suspected Crohn's disease that has not been confirmed using standard imaging techniques. Serum perinuclear antineutrophil cytoplasmic antibodies (pANCA) and anti-Saccharomyces cerevisiae antibodies (ASCA) have recently been added to our diagnostic armamentarium. Serology may prove to be useful in predicting the evolution of indeterminate colitis. Substantial progress could come from the improving of serologic and genetic tests in the future.
