Objective: Inflammatory bowel disease (IBD) is characterized by a low level of quality of life (QoL) and a high prevalence of anxiety and depression, especially in patients with poor QoL. We examined the effect of IBD-specific cognitive-behavioral therapy (CBT) on QoL, anxiety, and depression in IBD patients with poor mental QoL. Method: This study is a parallel-group multicenter randomized controlled trial. One hundred eighteen IBD patients with a low level of QoL (score ≤23 on the mental health subscale of the Medical Outcomes Study Short Form 36 Health Survey [SF-36]) were included from 2 academic medical centers (Academic Medical Center Amsterdam, VU University Medical Centre Amsterdam) and 2 peripheral medical centers (Flevo Hospital, Slotervaart Hospital) in the Netherlands. Patients were randomized to an experimental group receiving CBT (n = 59) versus a wait-list control group (n = 59) receiving standard medical care for 3.5 months, followed by CBT. Both groups completed baseline and 3.5 months follow-up assessments. The primary outcome was a self-report questionnaire and disease-specific QoL (Inflammatory Bowel Disease Questionnaire [IBDQ]). Secondary outcomes were depression (Hospital Anxiety and Depression Scale-Depression Subscale [HADS-D], Center for Epidemiologic Studies Depression Scale [CES-D]), anxiety (HADS-Anxiety Subscale [HADS-A]) and generic QoL (SF-36). Results: Data were analyzed both on intention to treat as well as on per protocol analysis (completed £ 5 sessions). CBT had a positive effect on disease-specific-QoL (Cohen's d = .64 for IBDQ total score), depression (Cohen's d = .48 for HADS-D and .78 for CES-D), anxiety (Cohen's d = .58 for HADS-A), and generic QoL (Cohen's d = 1.08 for Mental Component Summary of the SF-36; all ps < .01). Conclusions: IBD-specific CBT is effective in improving QoL and in decreasing anxiety and depression in IBD patients with poor QoL. Clinicians should incorporate screening on poor mental QoL and consider offering CBT. [ABSTRACT FROM AUTHOR]

Background and aims Adalimumab is an effective therapy for induction and maintenance of Crohn's disease. However, results in clinical trials don't necessarily reflect daily clinical practice. Therefore, we assessed real-life long-term clinical response to adalimumab in a large population-based cohort and identified clinical parameters affecting response Methods All consecutive patients in North-Holland that started adalimumab between 2003 and 2011 were included, of which medical charts were reviewed. Response to induction therapy was assessed after 3 months. Sustained benefit of maintenance therapy was calculated from Kaplan--Meier survival tables depicting ongoing adalimumab treatment. Regression analyses were performed to identify factors predicting response to adalimumab therapy. Results In total 438 Crohn's patients started adalimumab with 92.5% response to the induction phase. After 1 year 83.3% showed sustained benefit of maintenance treatment, followed by 74.0% after 2 years. Nevertheless, one third of patients were in steroid-free remission at the end of their follow-up. Response to induction was negatively affected by longer disease duration (OR 1.05; p < 0.01) and strictures (OR 3.73; p = 0.04). Increased CRP levels predicted higher rates of initial response (OR 0.31; p < 0.01). Concomitant thiopurines in the first 6 months of adalimumab treatment decreased the risk to fail maintenance therapy (HR 0.69, p = 0.05). Previous infliximab therapy did not affect response to adalimumab, however dose escalation was more often deemed necessary (p < 0.01). Conclusion Adalimumab was successful in the majority of patients, with 10% loss of response per subsequent year. Concomitant thiopurines might improve adalimumab maintenance treatment.

Background: Colonoscopic surveillance provides the best practical means for preventing colorectal cancer (CRC) in inflammatory bowel disease (IBD) patients. Strong evidence for improved survival from surveillance programmes is sparse.Method: The aim of this study was to compare tumour stage and survival of IBD patients with CRC who were a part of a surveillance programme with those who were not. A nationwide pathology database (PALGA (pathologisch anatomisch landelijk geautomatiseerd archief)) was consulted to identify IBD patients with CRC treated in all eight university hospitals in The Netherlands over a period of 15 years. Patients were assigned to the surveillance group when they had undergone one or more surveillance colonoscopies before a diagnosis of CRC. Patients who had not undergone surveillance served as controls. Tumour stage and survival were compared between the two groups.Results: A total of 149 patients with IBD-associated CRC were identified. Twenty-three had had colonoscopic surveillance before CRC was discovered. The 5-year CRC-related survival rate of patients in the surveillance group was 100% compared with 74% in the non-surveillance group (P=0.042). In the surveillance group, only one patient died as a consequence of CRC compared with 29 patients in the control group (P=0.047). In addition, more early tumour stages were found in the surveillance group (P=0.004).Conclusions: These results provide evidence for improved survival from colonoscopic surveillance in IBD patients by detecting CRC at a more favourable tumour stage.

Objectives: To prospectively assess dynamic contrast-enhanced (DCE-)MRI as compared to conventional sequences in patients with luminal Crohn's disease., Methods: Patients with Crohn's disease undergoing MRI and ileocolonoscopy within 1 month had DCE-MRI (3T) during intravenous contrast injection of gadobutrol, single shot fast spin echo sequence and 3D T1-weighted spoiled gradient echo sequence, a dynamic coronal 3D T1-weighted fast spoiled gradient were performed before and after gadobutrol. Maximum enhancement (ME) and initial slope of increase (ISI) were calculated for four colon segments (ascending colon+coecum, transverse colon, descending colon+sigmoid, rectum) and (neo)terminal ileum. C-reactive protein (CRP), Crohn's disease activity index (CDAI), per patient and per segment Crohn's disease endoscopic index of severity (CDEIS) and disease duration were determined. Mean values of the (DCE-)MRI parameters in each segment from each patient were compared between four disease activity groups (normal mucosa, non-ulcerative lesions, mild ulcerative and severe ulcerative disease) with Mann-Whitney test with Bonferroni adjustment. Spearman correlation coefficients were calculated for continuous variables., Results: Thirty-three patients were included (mean age 37 years; 23 females, median CDEIS 4.4). ME and ISI correlated weakly with segmental CDEIS (r=0.485 and r=0.206) and ME per patient correlated moderately with CDEIS (r=0.551). ME was significantly higher in segments with mild (0.378) or severe (0.388) ulcerative disease compared to normal mucosa (0.304) (p<0.001). No ulcerations were identified at conventional sequences. ME correlated with disease duration in diseased segments (r=0.492), not with CDAI and CRP., Conclusions: DCE-MRI can be used as a method for detecting Crohn's disease ulcerative lesions., (Copyright © 2012 Elsevier Ireland Ltd.

Background and Aims: Inflammatory Bowel Disease (IBD) patients with anxiety and/or depressive symptoms may not receive the care they need. Provision of care requires insight into the factors affecting these psychiatric symptoms. The study was designed to examine the extent to which: (1) IBD patients with anxiety and/or depressive symptoms receive mental treatment and (2) clinical and socio-demographic variables are associated with these symptoms., Methods: 231 adult IBD patients (79% response rate), attending a tertiary care center, completed standardized measures on anxiety and depressive symptoms (HADS), quality of life (SF-12) and mental health care use (TIC-P). Diagnosis and disease activity were determined by the gastroenterologist., Results: 43% had high levels of anxiety and/or depressive symptoms, indicative of a psychiatric disorder (HADS ≥ 8), of whom 18% received psychological treatment and 21% used psychotropic medication. In multivariate analysis, high disease activity was associated with anxiety (OR=2.72 | p<0.03) and depression (OR=3.36 | p<0.01), while Crohn's disease was associated with anxiety (OR=2.60 | p<0.03)., Conclusions: Despite high levels of anxiety and depressive symptoms and poor quality of life, psychiatric complaints in IBD patients were undertreated. Screening for and treatment of psychiatric symptoms should become an integral part of IBD medical care., (Copyright © 2011 European Crohn's and Colitis Organisation. Published by Elsevier B.V.

In the summary of product characteristics of infliximab (IFX), psychiatric side effects are reported to be rare, and in literature only limited data exist. This report presents a case of a patient with ulcerative colitis who developed a depression with psychotic symptoms during IFX therapy and made a suicide attempt 4 months after the initiation of therapy. Although the time between start of IFX therapy and onset of symptoms could suggest a correlation, this, of course, does not prove that IFX was the causative factor for his depression and suicide attempt., (Copyright © 2010.

Background: Patients with inflammatory bowel disease (IBD) and concurrent primary sclerosing cholangitis (PSC) have a higher risk of developing colorectal cancer (CRC) than IBD patients without PSC. The aim of this study was to investigate potential clinical differences between patients with CRC in IBD and those with CRC in IBD and PSC, as this may lead to improved knowledge of underlying pathophysiological mechanisms of CRC development., Methods: The retrospective study from 1980-2006 involved 7 Dutch university medical centers. Clinical data were retrieved from cases identified using the national pathology database (PALGA)., Results: In total, 27 IBD-CRC patients with PSC (70% male) and 127 IBD-CRC patients without PSC (59% male) were included. CRC-related mortality was not different between groups (30% versus 19%, P = 0.32); however, survival for cases with PSC after diagnosing CRC was lower (5-year survival: 40% versus 75% P = 0.001). Right-sided tumors were more prevalent in the PSC group (67% versus 36%, P = 0.006); adjusted for age, sex, and extent of IBD, this difference remained significant (odds ratio: 4.8, 95% confidence interval [CI] 2.0-11.8). In addition, tumors in individuals with PSC were significantly more advanced., Conclusions: The right colon is the predilection site for development of colonic malignancies in patients with PSC and IBD. When such patients are diagnosed with cancer they tend to have more advanced tumors than patients with IBD without concurrent PSC, and the overall prognosis is worse. Furthermore, the higher frequency of right-sided tumors in patients with PSC suggests a different pathogenesis between patients with PSC and IBD and those with IBD alone.

Conventional therapy for inflammatory bowel diseases rely on corticosteroids and 5-aminosalicylates combined with immunosuppressive agents for maintenance. These drugs are not always effective and may inflict serious side effects. Other therapies are therefore awaited. Infliximab, a monoclonal antibody against the pro-inflammatory cytokine TNF-alpha has been successfully applied as a treatment for Crohn's disease. The mechanism of action of this drug extends beyond the level of TNF-alpha scavenging and includes induction of apoptosis of effector cells. Numerous anti-TNF antibodies have been developed and are currently evaluated in clinical trials. Other targets for monoclonal antibodies include integrins and cytokines involved in T-cell differentiation and activation. Likewise recombinant proteins that moderate TNF bioactivity and lymphocyte function have been developed. The therapeutic effect of recombinant interleukin-10 seems to be dependent on local delivery of the protein. Antisense therapy targeting lymphocyte migration has also been tested in IBD. Finally, the conventional drug thalidomide and possibly MAP-kinase inhibitors may become novel treatment entities for IBD.
