There is evidence of an interaction between psychological factors and activity of inflammatory bowel disease (IBD). We examined the influence of depressive mood and associated anxiety on the course of IBD over a period of 18 months in a cohort of patients after an episode of active disease. In this prospective, longitudinal, observational study, 60 patients (37 women and 23 men) with clinically inactive IBD (Crohn disease, n = 47, 78%; ulcerative colitis, n = 13, 22%) were enrolled after a flare of disease. Psychological status, health-related quality of life (HRQOL), and disease activity were evaluated at baseline and then every 3 months for a period of 18 months by means of clinical and biological parameters, the Beck Depression Inventory (BDI), the Spielberger State-Trait Anxiety Inventory, the Inflammatory Bowel Disease Questionnaire, the Perceived Stress Questionnaire, and the Rating Form of Inflammatory Bowel Disease Patients Concerns. At baseline, depression (BDI ≥13 points) was found in 17 of 60 (28%) patients. Thirty-two patients (59%) experienced at least one relapse during the 18 months of follow-up. Regression analysis showed a significant correlation between BDI scores at baseline and the total number of relapses after 12 (p < .01) and 18 months (p < .01) of follow-up. Furthermore, depression scores at baseline correlated with the time until the first recurrence of the disease (p < .05). Anxiety and low HRQOL were also related with more frequent relapses during follow-up (p < .05 and p < .01, respectively). Psychological factors such as a depressive mood associated with anxiety and impaired HRQOL may exert a negative influence on the course of IBD. Therefore, assessment and management of psychological distress should be included in clinical treatment of patients with IBD.

BACKGROUND: Atypical teratoid/rhabdoid tumors are highly malignant embryonal central nervous system (CNS) tumors that were defined as an entity in 1996. As compared with other malignant CNS tumors, their biological behavior is particularly aggressive, but patients may benefit from an intensified treatment. Atypical teratoid/rhabdoid tumors display a complex histomorphology, which renders them prone to misdiagnosis. They occur predominantly in young children, with an estimated prevalence of 1% to 2% among all pediatric CNS tumors. However, population‐based data on the incidence of these tumors are not yet available.METHODS: A nation‐wide survey of malignant high‐grade CNS tumors (World Health Organization grade III/IV), diagnosed in children (aged birth to 14 years) from 1996 to 2006 was conducted by the Austrian Brain Tumor Registry. A central histopathology review was performed including the assessment of SMARCB1 (INI1) protein status.RESULTS: A total of 311 newly diagnosed, malignant CNS tumors were included. Atypical teratoid/rhabdoid tumors constituted the sixth most common entity (6.1%), referring to an age‐standardized incidence rate of 1.38 per 1,000,000 person‐years in children. Peak incidence was found in the birth to 2 years age group, where they were as common as CNS primitive neuroectodermal tumors and medulloblastomas. A total of 47.4% of atypical teratoid/rhabdoid tumors were initially diagnosed, whereas 52.6% were retrospectively detected by the central review. The 5‐year survival of atypical teratoid/rhabdoid tumor patients was 39.5%, with 66.7% in the correctly diagnosed group versus 15.0% in the not recognized group (P = .0469).CONCLUSIONS: Clinicians and pathologists should be aware of the high incidence of atypical teratoid/rhabdoid tumors in young children to optimize diagnostic and therapeutic management of patients with these tumors.

Anemia often complicates Crohn disease and affects quality of life. To evaluate the efficacy of intravenous iron alone and in combination with erythropoietin for the treatment of anemia associated with Crohn disease. Double-blind, randomized, placebo-controlled trial with a subsequent open-label phase. University-based gastroenterology outpatient clinic. 40 patients with Crohn disease and a hemoglobin concentration of 10.5 g/dL or less. All patients received intravenous iron saccharate for 16 weeks. During the blinded phase of the trial, they received either erythropoietin or placebo. During the open phase, the erythropoietin dose was increased in nonresponders who had received erythropoietin and erythropoietin therapy was initiated in nonresponders who had received placebo. Response was defined as an increase in hemoglobin concentration of 2 g/dL or more. 15 of 20 patients in the placebo group (75% [95% CI, 51% to 91%]) and 18 of 19 patients in the erythropoietin group (95% [CI, 74% to 100%]) responded to intravenous iron (P = 0.20). The erythropoietin group had a higher cumulative response rate (P = 0.036) and a more pronounced mean increase in hemoglobin concentration (4.9 g/dL in the erythropoietin group compared with 3.3 g/dL in the placebo group, a difference of 1.6 g/dL [CI, 0.6 g/dL to 2.5 g/dL]; P = 0.004). In the open phase, all 6 previous nonresponders had a response. Hematologic response was associated with improved quality of life (P = 0.03). Most patients who have anemia associated with Crohn disease respond to intravenous iron alone. Erythropoietin has additional effects on hemoglobin concentrations.
