Variceal bleeding is frequently the initial presentation of a previously unknown cirrhosis. Portal hypertension and its complications without liver cirrhosis should raise the possibility of presinusoidal portal hypertension, and the diagnosis of hepatoportal sclerosis. These patients need to be investigated for coagulation disorders. A hypercoagulable state is often associated. Risks and benefits of anticoagulation should be further investigated in these patients.

Uncommon but classically described, intestinal carcinoid tumors represent a variety of neuroendocrine tumors. Able to secrete amines and hormones, they can produce characteristic symptoms called "carcinoid syndrome". A cardiopathy is sometimes associated with the disease and carries a high risk of mortality and morbidity. [less ▲]

Crohn's disease (CD) is a multifactorial disease with genetic heterogeneity. TNF-alpha plays a key role in the development of the mucosal lesions. The aim of our work was to study a single base pair polymorphism located in the promoter region of TNF gene, in a large population of CD patients with well defined phenotypes. One hundred and ninety-three patients with CD and 98 ethnically matched controls were studied. The -308 single base pair polymorphism of TNF gene was studied using an allele-specific polymerase chain reaction. Genotype and allelic frequencies were compared between patients and controls and between subgroups of patients defined by sex, age at diagnosis, familial history, location of disease, type of disease, extra-intestinal manifestations, and response to steroid treatment. In 29 patients a measure of TNF-alpha production by colonic biopsies was performed. The frequency of the allele TNF2 as well as the proportion of carriers of the allele TNF2 were slightly but not significantly lower in CD than in controls (11.9% versus 14.8% and 21.5% versus 27.6%, respectively). A more prominent difference in frequencies of allele TNF2 and in proportions of TNF2 carriers was found when comparing subgroups of patients. The frequency of allele TNF2 was significantly higher in steroid-dependent than in non-steroid-dependent disease (28.1% versus 10.3%; Delta = 17.8%, 95% confidence interval (CI) = 6.3-29.5%, P = 0.0027) and tended to be higher in colonic than in small bowel disease and in fistulizing than in stricturing disease. Furthermore, TNF2 carriers tended to be more frequent in patients with steroid-dependent than non-steroid-dependent disease (43.8% versus 19.3%; Delta = 24.5%, 95% CI = 3.6-45.4%, P = 0.022), in patients with fistulizing than stricturing disease (26.5% versus 9.6%; Delta = 16.9%, 95% CI = 1. 1-32.6%, P = 0.036), and in patients with colonic than small bowel disease (26.5% versus 11.1%; Delta = 15.4%, 95% CI = -0.8-31.6%, P = 0.063). Finally, patients carrying at least one copy of allele 2 were found to produce slightly more TNF-alpha at the colonic level. The -308 TNF gene polymorphism may have a slight influence on the behaviour of CD. The carriage of allele 2 may favour steroid-dependent disease and to a lesser extent fistulizing and colonic disease, possibly secondary to a more intense TNF-alpha-driven inflammatory reaction at the mucosal level.

OBJECTIVES: Corticosteroid dependency in Crohn's disease (CD) is characterized by the need for chronic use of corticosteroids to maintain clinical remission. Several definitions have been used. Depending on the definition, 10-30% of the patients are considered as corticosteroid dependent. The aim of the study was to define a clinical pattern of corticosteroid dependent CD patients. PATIENTS AND METHODS: Epidemiological and clinical characteristics were retrospectively compared between 20 corticosteroid dependent CD patients and 248 non-corticosteroid dependent CD patients by using univariate and multivariate analyses. Corticosteroid dependency was defined either by two successive relapses during the 2 months after discontinuing glucocorticoids (n=5) or by two successive relapses at dose tapering, after successful treatment of a flare-up by using glucocorticoids (n=15). RESULTS: Corticosteroid dependent CD patients were younger at diagnosis (P < 0.001), and were characterized by a higher frequency of colonic location (P< 0.05), but lower frequency of ileal location (P < 0.01), and higher ano-perineal location (P < 0.05). They were also more frequently smokers (P< 0.05) and users of contraceptive pills (P< 0.01). The inflammatory type of the disease was increased (P < 0.01), while the fibrostenotic type was decreased (P < 0.001) in corticosteroid dependent CD patients. By multivariate analysis, a smoking habit (P < 0.01), a colonic location (P < 0.05), a non-fibrostenotic type (P< 0.05) and a younger age at diagnosis (P< 0.05) were shown to be independently associated with corticosteroid dependency. CONCLUSIONS: This study suggests a clinical pattern associated with corticosteroid dependency. Whether this clinical pattern is simply associated with the dependency, or whether a primary decrease of corticosensitivity produces this clinical pattern, is not known. Further prospective studies will have to determine whether the presence of these clinical characteristics is predictive of corticosteroid dependency and whether this prediction will be useful for the management of this condition.
