Long-term success of GUT-directed group hypnosis for patients with refractory irritable bowel syndrome: a randomized controlled trial.

OBJECTIVES: Gut-directed hypnotherapy (GHT) in individual sessions is highly effective in the treatment of irritable bowel syndrome (IBS). This study aimed to assess the long-term effect of GHT in group sessions for refractory IBS. METHODS: A total of 164 patients with IBS (Rome-III-criteria) were screened, and 100 refractory to usual treatment were randomized 1:1 either to supportive talks with medical treatment (SMT) or to SMT with GHT (10 weekly sessions within 12 weeks). The primary end point was a clinically important improvement on several dimensions of daily life (assessed by IBS impact scale) after treatment and 12-month follow-up. The secondary end point was improvement in general quality of life (QOL; Medical Outcome Study Short-Form-36), psychological status (Hospital Anxiety Depression Scale) and reduction of single IBS symptoms. Analysis was by intention to treat. RESULTS: A total of 90 patients received allocated intervention. After treatment, 28 (60.8%) out of 46 GHT patients and 18 (40.9%) out of 44 SMTs improved (absolute difference 20.0%; 95% confidence interval (CI): 0-40.2%; P=0.046); over 15 months, 54.3% of GHT patients and 25.0% of controls improved (absolute difference 29.4%; 95% CI 10.1-48.6%; P=0.004). GHT with SMT improved physical and psychological well being significantly more than SMT alone (P<0.001). Gender, age, disease duration and IBS type did not have an influence on the long-term success of GHT. CONCLUSIONS: GHT improves IBS-related QOL, is superior to SMT alone, and shows a long-term effect even in refractory IBS.

Predictors of indeterminate IFN-γ release assay in screening for latent TB in inflammatory bowel diseases.

BACKGROUND: IFN-γ release assays (IGRA), widely used for latent tuberculosis screening prior to anti-TNF-α treatment, are limited by indeterminate results in patients under immunomodulatory (IM) therapy. The aim of our observational study was to delineate factors associated with indeterminate IGRA results. METHODS: A total of 190 patients with inflammatory bowel disease were included. IGRA was indeterminate if the result of IFN-γ concentration was < 0·35 IU mL(-1) for tuberculosis-specific antigens and < 0·5 IU mL(-1) for the positive control. Predictors for indeterminate results were delineated from multivariate logistic regression. RESULTS: IFN-γ release assays was indeterminate in 26/190 (13·7%) patients. Indeterminate IGRA were associated with lower serum albumin levels (odds ratio [OR] 0·88, 95% confidence interval [CI] 0·79-0·96), lower absolute lymphocyte count (OR 0·39, 95% CI 0·18-0·75) and double IM therapy (OR 2·98, 95% CI 0·95-8·90). Sub-analysis of IM therapy revealed an association of steroid therapy with indeterminate IGRA (OR 3·19, 95% CI 1·35-7·70). Hypoalbuminaemia increased the risk of indeterminate IGRA by (OR 2·97, 95% CI 1·03-8·61) and lymphopaenia by (OR 3·28, 95% CI 1·41-7·65). After a mean of 18·5 ± 14·4 days, retesting of IGRA in 18 patients with indeterminate results yielded 9 negative vs. 9 indeterminate results. CONCLUSIONS: Our results reveal associations of indeterminate IGRA with low serum albumin levels and absolute lymphocyte count and double IM therapy. IGRA testing appears best to be performed prior to initiation of IM therapy in patients with inflammatory bowel disease.

Midday and nadir salivary cortisol appear superior to cortisol awakening response in burnout assessment and monitoring.

Burnout and work-related stress symptoms of anxiety disorder and depression cause prolonged work absenteeism and early retirement. Hence, reliable identification of patients under risk and monitoring of treatment success is highly warranted. We aimed to evaluate stress-specific biomarkers in a population-based, "real-world" cohort (burnouts: n = 40, healthy controls: n = 26), recruited at a preventive care ward, at baseline and after a four-month follow up, during which patients received medical and psychological treatment. At baseline, significantly higher levels of salivary cortisol were observed in the burnout group compared to the control group. This was even more pronounced in midday- (p < 0.001) and nadir samples (p < 0.001) than for total morning cortisol secretion (p < 0.01). The treatment program resulted in a significant reduction of stress, anxiety, and depression scores (all p < 0.001), with 60% of patients showing a clinically relevant improvement. This was accompanied by a ~30% drop in midday cortisol levels (p < 0.001), as well as a ~25% decrease in cortisol nadir (p < 0.05), although not directly correlating with score declines. Our data emphasize the potential usefulness of midday and nadir salivary cortisol as markers in the assessment and biomonitoring of burnout.

High risk of transfusion-induced alloimmunization of patients with inflammatory bowel disease.

BACKGROUND: Anemia is highly prevalent in inflammatory bowel disease patients, and red blood cell transfusion is often indicated already at reproductive age. Both transfusion and pregnancy may induce red cell alloantibodies, potentially complicating further transfusions and pregnancies. As recent evidence suggests that inflammation may promote red cell antibody induction, the alloimmunization risk of these patients after allogenic erythrocyte exposure was investigated. METHODS: Red cell alloantibody status and clinical data were analyzed in 193 inflammatory bowel disease patients with a history of transfusion or pregnancy, and compared with transfused controls with noninflammatory diseases (n=357). RESULTS: In transfused patients with inflammatory bowel disease, a 2.5-fold-increased red cell antibody prevalence was found (10/119, 8.4%), compared with transfused sex-matched controls with noninflammatory diseases (12/357, 3.4%; P=.023). Patients with inflammatory bowel disease had fewer transfusions (mean 3.0 vs 4.2, P=.003) but higher C-reactive protein levels during transfusion than controls (mean 8.4 vs 5.4 mg/dL, P <.001). The red cell antibodies of inflammatory bowel disease patients were clinically significant, directed against different Rh, Kell, Duffy, or Lutheran blood group antigens, and associated with higher number of transfusions (odds ratio 1.57; 95% confidence interval, 1.03-2.39). Conversely, immunomodulatory therapy during transfusion showed negative association (odds ratio 0.12; 95% confidence interval, 0.02-0.61). Only 1.4% of inflammatory bowel disease patients with pregnancy alone had antibodies. CONCLUSIONS: Patients with inflammatory bowel disease exhibited a very high risk of transfusion-induced red cell alloimmunization, possibly potentiated by inflammation. Aside from a restrictive transfusion strategy, the implementation of prophylactic blood group phenotype matching of red cell concentrates (not only for ABO and RhD but also RhCcEe, Kell, Kidd, Duffy) could prevent antibody induction and associated complications in these patients.

Long-term outcome in patients with ulcerative colitis treated with intravenous cyclosporine A is determined by previous exposure to thiopurines.

BACKGROUND AND AIM: Rescue therapy with intravenous cyclosporine A (CsA) helps to avoid colectomy in a substantial proportion of patients with severe ulcerative colitis (UC) but the impact on long-term outcome remains unclear. Therefore, we aimed to define predictive factors for colectomy in patients treated with intravenous CsA for severely active UC. METHODS: A retrospective, single-center study with a minimum follow-up of 18 months was performed. RESULTS: A total of 64 patients were evaluable (median age 33 years [range 17-80 years], female 54.7%). Median intravenous CsA dose was 4 mg/kg/day (range 2-5mg/kg/day). After a median follow-up of 65 months (range 2-160 months), 19 patients (29.7%) underwent colectomy, 15 within 18 months. Of the various baseline parameters tested, only previous non-response to thiopurine treatment (p=0.006) was associated with an increased risk of colectomy. During 18 months follow-up, thiopurine-naïve patients receiving thiopurine maintenance therapy after intravenous CsA (32/64, 50.0%) underwent colectomy in 12.5% of cases. The colectomy rate was 27.3% among 22 patients previously non-responsive to thiopurines who continued treatment after intravenous CsA, compared to 50.0% in the 10 patients who discontinued thiopurines prior to intravenous CsA or who never received thiopurines (p=0.037). CONCLUSIONS: The long-term colectomy rate after intravenous CsA in patients with severely active UC was relatively low in our series compared to the literature. Concomitant treatment with thiopurines was the only predictor for a reduced risk of colectomy.
