After fifteen years of use, the anti-TNF antibodies have become the corner stone of the treatment of moderate and severe Crohn's disease. The skill acquired over the years through experimental trials and clinical experience leads to increased therapeutic efficacy and minimized risks. These antibodies are introduced increasingly earlier in Crohn's disease as well as in a broader range of patients, aiming at changing the natural history of the diseases by avoiding the development of intestinal tissue damage and complications.

Inflammatory bowel diseases are both environmental and genetic illnesses. More than one hundred genes or loci involved in the regulation of innate or acquired immune response as well as intestinal mucosa homeostasis have been identified. Environmental studies have been less numerous up to now and only smoking and appendectomy have been validated, as protector for ulcerative colitis, while smoking is clearly associated with an increased risk and more severe forms of Crohn's disease. An important role is also currently suspected for the intestinal flora and the dysbiosis described in inflammatory bowel disease could contribute to the triggering or the persistence of the inflammation. New therapeutic strategies are currently studied, particularly aiming at targeting immune, inflammatory or homeostatic pathways corresponding to the predisposing gene variants. [less ▲]

Inflammatory bowel diseases (IBD) are classically divided in Crohn's disease (CD) and ulcerative colitis (UC). However, these two entities are still heterogeneous and a further classification in subphenotypes is necessary. Clinical subphenotypes are easy to use, do not necessitate complicated tests and can already give very important information for the management of the patients. In CD, clinical subphenotypes are based on age at diagnosis, disease location and disease behaviour. Age at diagnosis allows to differentiating paediatric CD, classical young adult onset and more seldom CD of the elderly. These categories are associated with a different risk of development of complications and disabling disease and may have partly different pathophysiology. The classification on disease behaviour, including stricturin, penetrating or uncomplicated disease may have an impact on reponse to medical treatment and need for surgery. Finally the classification based on location is particularly relevant since it has been associated with different types of complications. Particularly ileal disease has been associated with the risk of surgery and colonic (particularly rectal) disease, with the risk of perianal disease. In UC, the classification in subphenotypes is essentially based on disease location, distinguishing proctitis, left-sided colitis and extensive colitis. This subclassification also has a very significant clinical relevance since extensive colitis has been associated with and increased risk of colon cancer, colectomy and even in some studies, mortality.

Sexually transmitted diseases (STD) are a major public health problem because their incidence is increasing worldwide despite prevention campaigns and because they raise the risk of HIV infection. Anorectal localisations of STD are common among men who have sex with men (MSM) but can also be seen among heterosexuals (men or women). Transmission of such infections is due to anal sex or to other sexual behaviours like "fisting". Although some pathogens (like Human Papillomavirus-HPV) are common in gastroenterologist/proctologist consultations, others are not so well-known. Furthermore during the last years, sexual risky behaviours have led to resurgence of old affections (like syphilis) or to emergence of unknown diseases (like lymphogranuloma venereum) in our countries. This presentation tends to focus on clinical manifestation, diagnosis and treatment of different STD: HPV, Herpes Simplex Virus, Neisseria gonorrhoeae, Chlamydia trachomatis (in particularly lymphogranuloma venereum) and Treponema pallidum.

Pancreas graft survival has continuously improved over the years to become a main treatment option of uncontrolled complicated diabetes. Rejection remains the major challenge as it often goes unnoticed until severe damage of the graft manifests itself by elevated blood sugar. Pancreas enzymes monitoring in the blood and in the urine is a sensitive marker of rejection but lack of specificity. Biopsy remains the gold standard. Cystoscopy-guided biopsy of bladder-drained pancreas has a good success rate for obtaining tissue but the vesical drainage exposes to metabolic and urologic morbidity. Percutaneous pancreas biopsy can be performed with a low morbidity rate but severe complications can occur. We discuss a technique of pancreas transplantation with the drainage of exocrine secretions of the pancreatic graft in the recipient duodenum, which permits easy monitoring of the graft by upper endoscopy of the duodenum.

Background: Crohn's disease (CD) is a polygenic multifactorial heterogeneous disease. Anti-Saccharomyces Cerevisiae antibodies (ASCA) correlate highly with CD and are present in 50-80% of patients. The reason for ASCA positivity or negativity in CD is unknown. The aim of our work was to analyse clinical, epidemiological and genetic characteristics in ASCA + or ASCA- CD patients. Methods : 113 patients with CD were tested for ASCA (IgA and IgG) by using a commercial kit (Medipan Diagnostica). Age, gender, systemic manifestations, familial form of disease, age at diagnosis, location and behaviour of the disease, smoking habit as well as genotyping for -308 TNF gene polymorphisms were determined. Results : 38.9% CD patients were negative for both IgA and IgG ASCA while 61.1% were ASCA positive (respectively IgA and IgG : 31.9%; IgA only : 9.7%; IgG only : 19.5%). The only significant difference between ASCA+ and ASCA- patients was for smoking habit : there were 29% smokers in ASCA+ versus 50% in ASCA- CD patients (P = 0.03). This low proportion of smokers was more prominent in ASCA IgA+ patients than in isolated ASCA IgG+ patients (25.6% versus 45.5%) and was minimal in patients with high titers of ASCA IgA (0/8). Logistic regression showed smoking habit still borderline for significance (P = 0.057). Conclusions : Our results suggest a negative association between smoking and ASCA positivity in CD. This association was more prominent for ASCA IgA+. It indicates that smoking habit should be taken into account when analysing ASCA status in CD patients and may suggest an influence of smoking on immunization against intestinal material. [less ▲]

We examined immune and inflammatory activation during remission in patients with Crohn's disease who presented with various clinical profiles (prolonged remission vs. relapsing disease). Thirty-six patients with at least 3 years' follow-up starting from a remission period were studied retrospectively. Relapses were defined by a retrospective calculation of the Crohn's disease activity index or by the clinical judgement of the physicians in charge of the patients. Disease course over the study period was assessed by the mean number of annual relapses. Analysis used measurements during remission of the following: erythrocytes sedimentation rate, relative lymphocytosis, acid alpha1-glycoprotein, interleukin-6 (IL-6), and soluble interleukin-2 receptor (sIL-2R) serum levels. During the study period 21 patients experienced at least one relapse and 15 did not. Mean serum levels of sIL-2R and mean relative lymphocytosis in remission significantly discriminated between relapsing and nonrelapsing patients. Only the mean sIL-2R serum level was selected by multivariate analysis, with a cutoff value of 82 pM/1 (sensitivity of 76% and specificity of 80%). The only features correlated with mean number of annual relapses in the relapsing patients were mean serum levels of sIL-2R (r=0.58, P=0.015) and IL-6 in remission (r=0.45, P=0.039). Multivariate analysis demonstrated statistical significance only for the mean serum level of IL-6 (P=0.014). In Crohn's disease the persistent elevation in sIL-2R serum levels during remission corresponds to chronic active disease, while high serum levels of IL-6 in these patients is associated with a high frequency of relapse.

BACKGROUND AND STUDY AIMS: The small intestine is a potential origin of bleeding in patients with unexplained gastrointestinal tract hemorrhage or iron-deficiency anemia. Most reports on the investigation of these patients describe the use of upper tract enteroscopy. The diagnostic yield of combined upper and lower enteroscopy has not been widely assessed and remains to be clarified. The aim of this study was to assess the benefit of lower gastrointestinal tract enteroscopy in occult digestive bleeding. PATIENTS AND METHODS: Between 1 December 1995 and 15 January 1998, 54 patients with gastrointestinal bleeding of unknown origin were prospectively studied using upper and lower video push enteroscopy (44 for chronic iron-deficiency anemia and 10 for unexplained gastrointestinal tract hemorrhage with no potential site having been identified by other investigations). Examinations were done using a Olympus video enteroscope (SIF-100) under general anesthesia in a one-day clinic. An upper tract examination was done first, directly followed by the lower tract investigation. RESULTS: The upper tract enteroscopy was successful in 53 patients (98%) and retrograde ileoscopy in 21 patients (39%). In 18 (38%) cases the technical failure resulted from the impossibility of intubating the ileocecal valve. A potential source of upper gastrointestinal bleeding was detected in 35% of patients with chronic iron-deficiency anemia and in 20% of those with unexplained gastrointestinal tract hemorrhage. The most common lesion in the small bowel was angiodysplasia (25%). The lower tract video push enteroscopy disclosed 11 lesions in patients with chronic anemia. However the lesions, including two ileocecal valve cancers, were mainly located in the colon and had been missed by previous colonoscopy. No case of ileal lesion was detected in this group of patients. In patients with unexplained gastrointestinal tract hemorrhage, three lesions were detected but only one of these was in the ileum. Associated colonic and jejunal lesions were observed in three patients (5.5%). Overall, the diagnostic yield of lower video push enteroscopy was less than 2%. CONCLUSION: This prospective study has shown that using an enteroscope as a colonoscope in the management of patients with gastrointestinal bleeding of unknown origin is of little help. It might actually be more appropriate to perform a second colonoscopy. This however remains controversial and a prospective study is needed to answer that question. [less ▲]

BACKGROUND/AIMS: Relapses of Crohn's disease are difficult to predict. We assessed the value of serum level of interleukin-6, tumour necrosis factor alpha (TNF-alpha) and soluble TNF receptors as predictors of relapse in quiescent Crohn's disease. PATIENTS/METHODS: Thirty-six patients with inactive Crohn's disease, treated or not, were included. Various clinical and biological parameters, including interleukin-6, TNF-alpha and soluble TNF receptors serum levels were measured at inclusion in the study and the patients were followed clinically for 1 year. The relapse was defined as a Crohn's Disease Activity Index (CDAI) greater than 150 with an increase greater than 100 compared to the inclusion value. We analysed the ability of these parameters to predict relapse in parallel to clinical characteristics and other laboratory parameters. RESULTS: Among the 32 variables tested, interleukin-6 serum level had the greatest ability to predict the time-to-relapse, with 17-fold chance of relapse over a 1-year period for patients with an interleukin-6 serum level greater than 20 pg/ml than for patients with a lower level (P < 0.001). A high serum level of the soluble TNF receptors p55 and p75 also had significant predictive value, in contrast to TNF-alpha serum levels. An interleukin-6 serum level greater than 20 pg/ml and either an acid alpha-1-glycoprotein level greater than 1.1 g/l or a soluble interleukin-2 receptor serum level greater than 95 pM/l were risk factors selected by a stepwise multivariate analysis. In both models a good prognosis group was defined by the absence of the two risk factors, a bad prognostic group by the presence of the two risk factors and an intermediate in between. With both models, the good prognosis group included 17 patients who experienced no relapse over the 1-year follow-up, whereas all patients (seven with the first model and six with the second) in the bad prognosis group had a relapse during the follow-up. Looking specifically at two homogeneous subgroups including either naturally/5-aminosalicylic acid (5-ASA) quiescent or corticoid quiescent patients, a very good predictive value for interleukin-6 serum concentration was also found. CONCLUSION: Interleukin-6 serum level alone or in association with other biological parameters such as acid alpha-1-glycoprotein or the soluble interleukin-2 receptor serum level may be useful for predicting the course of the disease in patients with quiescent Crohn's disease.

The aim of our study was to determine the effect of a rectocolonic preimmunization with ovalbumin on the systemic immune response induced by a subsequent subcutaneous injection of this antigen in Balb/c mice. One rectocolonic, but not intragastric, administration of 25 mg of ovalbumin induced a detectable increase in serum anti-ovalbumin antibody level. The level reached was however much lower than after subcutaneous injection. Both intragastric and rectocolonic immunization with ovalbumin induced specific systemic cellular tolerance. However, after rectocolonic, but not intragastric, preimmunization there was no systemic humoral tolerance to this antigen. These differences in systemic immune responses after rectocolonic or intragastric administration of ovalbumin could be due to different stimulation of the systemic immune system or to differences between the colonic and small bowel mucosal immune system, which remain to be elucidated.

In Crohn's disease, the activity of the disease is difficult to evaluate and the evolution of the disease is difficult to predict. The soluble interleukin-2 receptor serum level has been reported to correlate with clinical activity of the disease and with mucosal immune activation. We compared serum soluble interleukin-2 receptor to classical inflammatory markers and other immune parameters in the assessment of clinical disease activity and prediction of relapse in patients with Crohn's disease. Soluble interleukin-2 receptor serum levels correlated well with the Crohn's disease activity index, and multivariate analysis showed that this correlation was independent of the other inflammatory and immune markers. The correlation was not greater, However, than that between some inflammatory markers, such as ESR, and Crohn's disease activity index. Longitudinal follow-up showed that a high soluble interleukin-2 receptor serum level was highly predictive of relapse. Multivariate analysis showed that the soluble interleukin-2 recepteur serum level was complementary to other inflammatory and clinical markers in the prediction of relapse of disease. We conclude that soluble interleukin-2 receptor is of use in monitoring Crohn's disease, particularly in prediction of relapse. [less ▲]
