Abstract: BACKGROUND AND AIMS: Stress is often perceived by patients with inflammatory bowel disease (IBD) as the leading cause of their disease. The aim of this study was to assess whether stress, evaluated through life event (LE) occurrence, is associated with IBD onset. METHODS: Incident cases of IBD, including 167 patients with Crohn's disease (CD) and 74 with ulcerative colitis (UC), were compared with two control groups, one of 69 patients with acute self-limited colitis (ASLC) and another of 255 blood donors (BDs). Stress was assessed using Paykel's self-questionnaire of LEs. Only LEs occurring within 6 months before the onset of symptoms in IBD cases and ASLC controls and before blood donation in BD controls were registered. Anxiety and depression were assessed using Bate's and Beck's questionnaires, respectively. RESULTS: In univariate analysis, occurrence of LEs was more frequent in the 6-month period prior to diagnosis in CD cases than in UC cases or either control group. After adjustment for depression and anxiety scores as well as other characteristics such as smoking status and sociodemographic features, this association appeared no longer significant. No associations were noted between occurrence of LEs and onset of UC relative to controls. CONCLUSIONS: Despite its separate association with CD, LE occurrence does not appear to be an independent risk factor for IBD onset.

Abstract: OBJECTIVE: To assess the incidence and location at diagnosis of inflammatory bowel disease in children and adolescents in northern France between 1988 and 1999. METHODS: A 12-year prospective population-based study was conducted by gastroenterologists and pediatric gastroenterologists of northern France (1,312,141 children <17 years of age). RESULTS: From 1988 to 1999, 509 cases of childhood inflammatory bowel disease were recorded (7.2% of all inflammatory bowel disease cases in Northern France): 367 Crohn disease, 122 ulcerative colitis and 20 indeterminate colitis. The mean standardized incidence was 3.1/10(5) for inflammatory bowel disease as a whole (2.3 for Crohn disease, 0.8 for ulcerative colitis and 0.12 for indeterminate colitis). Crohn disease location at diagnosis was: small bowel and colon (71%), colon only (10%) and small bowel only (19%). Location of initial ulcerative colitis was: proctitis (11%), left colitis (57%) and pancolitis (32%). Although ulcerative colitis incidence remained stable (0.8), Crohn disease incidence increased from 2.1 in 1988 to 1990 to 2.6 in 1997 to 1999 (P = 0.2). CONCLUSIONS: The incidence of Crohn disease in the children of northern France showed an increasing trend (20%; not significant) during the 12-year period while the incidence of ulcerative colitis remained stable. In the entire population(children and adults)the incidence of Crohn disease increased significantly (+23%; P < 0.001), while the incidence of ulcerative colitis decreased (-17%; P < 0.0001).

Abstract: Arterial thrombotic accidents in the course of inflammatory bowel disease are rare. They generally affect young adults whose disease is active. We observed a case of aortic and renal arterial thrombosis in a 40-year-old woman who was suffering from ulcerative colitis. Surgical thrombectomy ensured good postoperative results, without any ischemic or renal sequelae. Six days later the patient presented with distal thrombosis of the splenic artery, which receded under anticoagulant treatment. The physiopathology of thromboembolic events in the course of inflammatory bowel disease is uncertain. Such events result from a state of hypercoagulability of various mechanisms, which can be observed in active inflammatory bowel disease. This possibility of serious arterial thrombosis argues in favor of long-term anticoagulant treatment when inflammatory bowel disease is active.
