INSPIRE study: does stress management improve the course of inflammatory bowel disease and disease-specific quality of life in distressed patients with ulcerative colitis or Crohn's disease? A randomized controlled trial.

BACKGROUND: The use of stress management psychotherapy is hypothesized to produce greater improvement in disease course and disease-specific quality of life (IBDQ) compared to usual medical care alone in patients with ulcerative colitis (UC) or Crohn's disease (CD) showing high levels of stress (based on the Perceived Stress Questionnaire [PSQ]). METHODS: Fifty-eight patients with UC and 56 patients with CD who had experienced continuous disease activity or had relapsed over the previous 18 months, with an activity index for UC or CD ≥ 4, a PSQ ≥ 60, and without serious psychiatric disorders or other serious medical conditions were randomized to receive either treatment as usual (TAU) or TAU plus stress management psychotherapy. Psychotherapy consisted of three group sessions (psychoeducation, problem-solving, relaxation) and 6-9 individual sessions based on cognitive behavior therapy-related methods with 1-3 booster sessions at 6 and 12 months follow-up. Gastroenterologists blinded to intervention group assessed disease activity and course at baseline and at 3, 6, 12, and 18 months. Patients completed the IBDQ at baseline, 6, 12, and 18 months. RESULTS: The intervention did not improve disease or reduce relapse; however, it increased the IBDQ score (P = 0.009, mean differences 16.3 [SD 6.1]). On analysis of UC and CD separately, improvement of IBDQ was only found in the UC group. CONCLUSIONS: Stress management psychotherapy does not appear to improve disease course or reduce relapse in patients with IBD. It might improve quality of life, particularly in patients with UC.

Rectal visceral sensitivity in women with irritable bowel syndrome without psychiatric comorbidity compared with healthy volunteers.

BACKGROUND: Psychiatric comorbidity and visceral hypersensitivity are common in patients with irritable bowel syndrome (IBS), but little is known about visceral sensitivity in IBS patients without psychiatric disorders. AIM: We wanted to examine rectal visceral sensitivity in IBS patients without comorbid psychiatric disorders, IBS patients with phobic anxiety and healthy volunteers. METHODS: A total of thirty-eight female, non-constipated IBS patients without psychiatric disorders and eleven female IBS patients with phobic anxiety were compared to nine healthy women using a barostat double random staircase method. The non-psychiatric patients were divided into those with diarrhoea predominant symptoms and those with alternating stool habits. RESULTS: The IBS patients without psychiatric disorders had normal visceral pressure thresholds. However, in the diarrhoea predominant subgroup, the volume discomfort threshold was reduced while it was unchanged in those with alternating stool habits. The phobic IBS patients had similar thresholds to the healthy volunteers. The rectal tone was increased in the non-psychiatric IBS patients with diarrhoea predominant symptoms and in the IBS patients with phobic anxiety. CONCLUSIONS: Non-constipated IBS patients without psychiatric disorders had increased visceral sensitivity regarding volume thresholds but normal pressure thresholds. Our study suggests that the lowered volume threshold was due to increased rectal tone.

The INSPIRE study: do personality traits predict general quality of life (Short form-36) in distressed patients with ulcerative colitis and Crohn's disease?

OBJECTIVE: To assess the role of personality as a predictor of Short form-36 (SF-36) in distressed patients (perceived stress questionnaire, PSQ) with ulcerative colitis (UC) and Crohn's disease (CD). MATERIAL AND METHODS: Fifty-four patients with CD and 55 with UC (age 18-60 years) who had relapsed in the previous 18 months, i.e. with an activity index (AI) for UC or CD> or =4, PSQ> or =60, and without severe mental or other major medical conditions, completed the Buss-Perry Aggression Questionnaire (BPA), the Neuroticism and Lie scales of the Eysenck Personality Questionnaire (EPQ-N and -L), the Multidimensional Health Locus of Control Scale (LOC) (Internal (I), Powerful Other (PO), Chance (C)), the Toronto Alexithymia Scale (TAS) and the SF-36. RESULTS: Multiple linear regression analyses controlling for gender, age and clinical disease activity (AI) in separate analyses for UC and CD showed that the mental and vitality subscales were predicted by neuroticism in both UC and CD. The highest explained variance was 43.8% on the "mental" subscale in UC. The social function subscale was related to alexithymia only in UC, while the role limitation and pain subscales were related to personality in CD only. The physical function subscale related differently to personality in UC and CD. CONCLUSIONS: While mental and vitality subscales were predicted by neuroticism in both UC and CD, other subscales had different relationships to personality, suggesting different psychobiological interactions in UC and CD.

The INSPIRE study: are different personality traits related to disease-specific quality of life (IBDQ) in distressed patients with ulcerative colitis and Crohn's disease?

BACKGROUND: To explore the relationship between personality and disease-specific quality of life [Inflammatory Bowel Disease Questionnaire (IBDQ)] in distressed [Perceived Stress Questionnaire (PSQ)] patients with ulcerative colitis (UC) and Crohn's disease (CD). METHODS: Included in the study were 56 patients with UC and 54 patients with CD ranging in age from 18 to 60 years with a relapse in the previous 18 months, a UC or CD activity index 4, a PSQ 60, and without serious mental or other serious medical condition. The patients completed the Buss-Perry Aggression Questionnaire, the Neuroticism and Lie (social conformity/desirability) scales of the Eysenck Personality Questionnaire, the Multidimensional Health Locus of Control (LOC) Scale [Internal (I), Powerful Other (PO), Chance (C)], the Toronto Alexithymia Scale, and the IBDQ. RESULTS: In linear regression controlling for sex, education (years), and clinical disease activity (AI) in separate analyses of UC and CD patients, higher IBDQ score was related to less social conformity in CD and less neuroticism in UC; higher emotional function score was related to less neuroticism in both CD and UC and less PO-LOC in UC. Higher social function score was related to less social conformity in CD and lower I-LOC and PO-LOC in UC. Bowel function and systemic symptoms were unrelated to personality in either UC or CD. CONCLUSIONS: Although the emotional function subscale was related to neuroticism in both UC and CD, the social function subscale and total IBDQ were related to different personality traits in UC and CD. Personality traits should be taken into account when using IBDQ in studies.

Autonomic function at rest and in response to emotional and rectal stimuli in women with irritable bowel syndrome.

Our aim was to study autonomic function in patients with Irritable bowel syndrome (IBS) without constipation and psychiatric comorbidity. Respiratory sinus arrhythmia (RSA) (representing cardiac vagal activity), skin conductance (representing sympathetic activity) and heart rate were measured at baseline and as a response to emotional stress and rectal discomfort in 33 women with IBS and 21 healthy women. Baseline heart rate was higher in the patients than in the healthy volunteers. Both groups had decreased RSA and increased heart rate and skin conductance level when exposed to emotional stress, but the autonomic responses did not differ significantly between the groups. At discomfort threshold the patients had increased heart rate response and skin conductance amplitude when compared to the healthy volunteers. Correlations between autonomic responses and the depression subscale of the Hospital Anxiety and Depression (HAD) score differed markedly between the diarrhea-predominant IBS patients and the IBS patients with alternating stool habits.

Visceral sensitivity in irritable bowel syndrome and healthy volunteers: reproducibility of the rectal barostat.

The reproducibility of rectal visceral sensitivity using the barostat double-random staircase method was evaluated. We tested 15 healthy women and 18 women with irritable bowel syndrome twice. Pressure, volume, and tension were measured at first sensation of gas, stool, and discomfort. There was no significant difference between test and retest. Three different indexes were used as measures of reproducibility. The intraclass correlation coefficients, considered to demonstrate acceptable reproducibility when higher than 0.80, ranged from 0.76 to 0.93 in the healthy volunteers and from 0.53 to 0.88 in the patients. The pooled coefficients of variation ranged from 10 to 24% in the healthy volunteers and from 11 to 49% in the patients. The repeatability coefficients are also given. The results indicate that barostat visceral sensitivity measurements in the rectum may be applicable when comparing groups of subjects.

Exposure therapy and sertraline in social phobia: I-year follow-up of a randomised controlled trial.

BACKGROUND: Maintenance of treatment effect is important for the choice of treatment for social phobia. AIMS: To examine the effect of exposure therapy and sertraline 28 weeks after cessation of medical treatment. METHOD: In this study 375 patients with social phobia were randomised to treatment with sertraline or placebo for 24 weeks, with or without the addition of exposure therapy. Fifty-two weeks after inclusion, 328 patients were evaluated by the same psychometric tests as at baseline and the end of treatment (24 weeks). RESULTS: The exposure therapy group and the placebo group had a further improvement in scores on social phobia during follow-up: mean change in the Clinical Global Impression - Social Phobia overall severity score was 0.45 (95% CI 0.16-0.65, P < 0.01) for the exposure group, and 0.25 (95% CI 0.00-0.48, P < 0.05) for the placebo group. At week 52 the sertraline plus exposure group and the sertraline-alone group had a significant deterioration on the 36-item Short Form Health Survey compared with exposure alone. CONCLUSIONS: Exposure therapy alone yielded a further improvement during follow-up, whereas exposure therapy combined with sertraline and sertraline alone showed a tendency towards deterioration after the completion of treatment.

[Irritable bowel syndrome--a multifactorial disease in children and adults]. / Irritabel tarm-syndrom multifaktoriell lidelse hos barn og voksne.

Irritable bowel syndrome is the most frequent gastrointestinal disorder in Norway. Though there has been huge research activity in the field, no proven single aetiology or effective treatment has emerged. Consensus-based clinical diagnostic criteria have not yet brought diagnostic clarity. Possibly, there are dysfunctions in the processing of sensory stimuli in the "brain-gut" axis that may cause visceral hypersensitivity and secondary motility changes. In some patients, a multifactorial explanation of the mechanisms is useful, including stressful life events or other psychological factors. Psychiatric co-morbidity is probably the most important maintaining factor. Irritable bowel syndrome may serve as a model for the study of the interaction between biological, psychological and social factors in functional disorders. A good therapeutic relationship between the physician and the patient is an important element in the treatment approach.

[Chronic pelvic pain in women]. / Kroniske bekkensmerter hos kvinner.

BACKGROUND: This paper reviews empirical and clinical evidence of the aetiology and treatment of medically unexplained chronic pelvic pain in women. MATERIAL AND METHODS: Clinical experience from an ongoing randomised treatment trial supplemented by computer-assisted reviews of studies obtained by a Premedline and Medline search (1996 to February 2002) and data from the Cochrane Database of Systematic Reviews and the EBM database of Abstracts of Reviews of Effectiveness. RESULTS: The aetiology of medically unexplained chronic pelvic pain is disputed but likely to be multifactorial. A history of interpersonal difficulties and a stressful life is common, and comorbid psychiatric disorders occur frequently. No treatment of choice emerges from the few controlled treatment trials, though a flexible biopsychosocial approach seems the most promising. INTERPRETATION: Empathic medical evaluation and follow-up within a biopsychosocial framework is recommended. Analgesic, hormonal and, if appropriate, surgical treatment can relieve pain. Additional benefits may be obtained by adding sensory awareness-directed physiotherapy aimed at changing painful muscle tensions, body attitude, movement pattern and dysfunctional respiration pattern. Co-morbid psychiatric disorders should be diagnosed and treated. Cognitive-behavioural stress management intervention aimed at improving coping with pain and current life-situation may be indicated in a subsample of patients.

[Functional somatic diseases--a review]. / Funksjonelle somatiske lidelser--en oversikt.

Functional somatic illness is a clinical concept used to define medically unexplained somatic symptoms considered to express psychological distress. Functional somatic illness may express underlying psychiatric disorders (e.g. fibromyalgia due to non-fearful panic disorder, irritable bowel syndrome due to bipolar disorder). Sustained physiological activation caused by stressful life events combined with catastrophic thinking may be another cause. Functional somatic illness may also be caused by classic conditioning of physiological responses that may have been triggered by biological or emotional stimuli. Operant conditioning may also be a cause. The therapeutic alliance relies on acceptance of the reality of the subjective complaints, without a priori acceptance of the patient's attribution of the cause of the symptoms. We recommend initial exploration of the patient's own ideas about aetiology, including appropriate medical tests. The physician should then change the agenda to a biopsychosocial perspective and identify current stressors and psychosocial variables that reinforce symptoms. Only a few randomised trials have been performed. They suggest that psychological treatment should be systematic and structured, with a focus on information, alternative ways of perception, and problem solving. Active forms of physiotherapy and psychopharmacological drugs may be of some benefit in selected patients.

Continued symptomatic improvement three to five years after transmyocardial revascularization with CO(2) laser: a late clinical follow-up of the Norwegian Randomized trial with transmyocardial revascularization.

OBJECTIVES: The goals of this study were to assess late clinical outcome and left ventricular ejection fraction (LVEF) after transmyocardial revascularization with CO(2) laser (TMR). BACKGROUND: During the 1990s TMR emerged as a treatment option for patients with refractory angina not eligible for conventional revascularization. Few reports exist on clinical effects and LVEF >3 years after TMR. METHODS: One hundred patients with refractory angina not eligible for conventional revascularization were block-randomized 1:1 to receive continued medical treatment or medical treatment combined with TMR. The patients were evaluated at baseline and after 3, 12 and 43 (range: 32 to 60) months with end points to angina, hospitalizations due to acute myocardial infarctions or unstable angina, heart failure and LVEF. Mortality was registered and MOS 36 Short-Form Health Survey answered at baseline and after 3, 6 and 12 months. RESULTS: Forty-three months after TMR, angina symptoms were still significantly improved, and unstable angina hospitalizations reduced by 55% (p < 0.001). Heart failure treatment (p < 0.01) increased, whereas the number of acute myocardial infarctions, LVEF and mortality was not affected. Quality of life was improved 3, 6 and 12 months after TMR. CONCLUSIONS: Forty-three months after TMR, angina symptoms and hospitalizations due to unstable angina were significantly reduced, heart failure treatment increased and LVEF and mortality were seemingly unaffected.

Psychiatric comorbidity and hostility in patients with psychogenic nonepileptic seizures compared with somatoform disorders and healthy controls.

PURPOSE: To investigate the prevalence of psychiatric comorbidity and level of anxiety, depression, and aggression in patients with psychogenic nonepileptic seizures compared with those in patients with somatoform disorders and healthy controls. METHODS: Twenty-three patients with psychogenic nonepileptic seizures (PNESs) and 23 age- and sex-matched patients with somatoform disorders (SDs) underwent a clinical and a semistructured psychiatric interview (MINI) and filled in the Hospital Anxiety and Depression scale (HAD) and the Aggression Questionnaire (AQ). Twenty-three sex- and age-matched controls without psychopathology also underwent a clinical interview and completed the HAD and AQ. RESULTS: PNES reported more minor head injuries in the past than did the two comparison groups, and more unspecific EEG dysrhythmias were observed on EEG. Twenty-one PNES patients and 18 with SDs had comorbid psychiatric diagnoses. However, the mean number of comorbid psychiatric diagnoses was higher in the PNES group (1.9 +/- 0.3 compared with 1.5 +/- 0.5 in the SD group; p = 0.003). Ten PNES patients additionally had a somatoform pain disorder, and seven had an undifferentiated somatoform disorder. Both patient groups reported significantly higher levels of anxiety, depression, and anger than did the healthy controls, but the PNES patients had significantly higher level of hostility than both comparison groups. CONCLUSIONS: Increased psychiatric comorbidity is known to be associated with poorer response to regular interventions, and hostility is associated with more hostile coping patterns, often interfering with treatment compliance. Thus the increased prevalence of soft neurologic signs and comorbid psychiatric disorders and increased hostility as well in the PNES group, emphasizes that assessment and treatment of patients with PNES referred to a tertiary center requires an integrated approach involving both neurologic and psychiatric resources.
