Using a sample of over 125 patients with irritable bowel syndrome (IBS) who were treated with cognitive therapy administered in small groups, we sought to predict end of treatment and 3-month follow-up improvement in two changes indices of gastrointestinal (GI) symptoms (Pain/Discomfort Index which assessed change in abdominal pain, abdominal tenderness and bloating and Bowel Regularity Index which assessed change in diarrhea and constipation). We also sought to predict scores on IBS specific quality of life (QOL) and overall level of psychological distress using the Global Severity Index (GSI) of the Brief Symptom Inventory (BSI). Significant, but modest, levels of prediction were found for prediction of improvement in GI symptoms (4-15% of variance). Stronger significant prediction was obtained for the QOL and global psychological distress measure with R(2)'s ranging from 0.36 to 0.50. A wide variety of demographic, GI symptom, psychological status and psychiatric status variables entered the final prediction equations.

Recurrent abdominal pain (RAP) is associated with increased health care visits and school absences. In adults suffering from functional pain, psychosocial factors determine illness behavior and we aimed to investigate its role among children. A community sample of 40 RAP consulters, 41 RAP nonconsulters, and 36 pain-free controls and their mothers completed questionnaires on GI and non-GI symptoms, school absences, psychological symptoms, coping, self-esteem, and behavioral and cognitive responses to RAP. T-tests showed significant differences between RAP and controls in (1) GI and non-GI symptoms and school absences, (2) child distress and passive coping, and (3) mother's IBS severity, somatization, and fears about RAP. RAP consulters reported the same levels of GI symptoms and psychological distress as nonconsulters but missed significantly more school and their mothers reported more fears about RAP. Severity of symptoms and psychological distress did not predict consulting behavior. Only maternal fears about abdominal symptoms differentiated consulters from nonconsulters.

Women with irritable bowel syndrome often report premenstrual distress syndrome and dysmenorrhea. A descriptive, four-group comparison design was used to compare the symptoms and psychological distress levels of women with irritable bowel syndrome (age 18-45 years) with and without dysmenorrhea and premenstrual distress syndrome. Data from three studies on women with irritable bowel syndrome (n = 226) collected between 1995 and 2004 were combined. Of these, 38 had self-reported irritable bowel syndrome with dysmenorrhea and premenstrual distress syndrome, 59 had irritable bowel syndrome with premenstrual distress syndrome, 15 had irritable bowel syndrome and dysmenorrhea, and the remaining 114 had irritable bowel syndrome only. Participants completed the Symptom Checklist-90 Revised and a symptom diary. Pain symptoms and computed scales of anxiety, depression, anger, and cognitive difficulties were compared during the luteal phase, menses phase, and for the change from luteal to menses phases. Premenstrual distress syndrome and dysmenorrhea had a strong impact on uterine cramping at menses, and a weaker effect on other pain symptoms at both luteal and menses phases. Premenstrual distress syndrome was associated with higher depression, anger, and cognitive problems at both luteal and menses phases; however, it was not associated with a greater increase from luteal to menses phases for any symptoms other than uterine cramping. The multiple symptoms reported by women with both irritable bowel syndrome and premenstrual distress syndrome suggest that this group may be particularly challenging to treat and may require a multicomponent (e.g., education, diet, relaxation, cognitive restructuring) approach.

Irritable bowel syndrome affects approximately 10-15% of the European population, although prevalence rates vary depending on the classification used and the country surveyed. This may be due to differences in patterns of medical care and diagnosis of the condition. Up to 70% of individuals with irritable bowel syndrome may not have been formally diagnosed. The disorder affects 1.5-3 times as many women as men and poses a significant economic burden in Europe, estimated at euro 700-euro 1600 per person per year. It also reduces quality of life and is associated with psychological distress, disturbed work and sleep, and sexual dysfunction. It is a chronic disorder, which affects many individuals for more than 10 years. Most patients are managed in primary care, although some are referred to gastroenterologists and other specialists. Patients with irritable bowel syndrome undergo more abdomino-pelvic surgery than the general population. We propose that a positive diagnosis of the condition may avoid the delay in diagnosis many patients experience. We conclude that, in Europe, there are significant unmet needs including lack of familiarity with irritable bowel syndrome, difficulties in diagnosis and lack of effective treatments for the multiple symptoms of the disorder. The development of pan-European guidelines for irritable bowel syndrome will benefit patients with this condition in Europe.

Functional dyspepsia represents a heterogeneous group of gastrointestinal disorders marked by the presence of upper abdominal pain or discomfort. Although its precise definition has evolved over the last several decades, this disorder remains shrouded in controversy. The symptoms of functional dyspepsia may overlap with those of other functional bowel disorders including irritable bowel syndrome and non-erosive reflux disease. There may be coexistent psychological distress or disease complicating its presentation and response to therapy. Given the prevalence and chronicity of functional dyspepsia, it remains a great burden to society. Suspected physiological mechanisms underlying functional dyspepsia include altered motility, altered visceral sensation, inflammation, nervous system dysregulation and psychological distress. Yet the exact pathophysiological mechanisms that cause symptoms in an individual patient remain difficult to delineate. Numerous treatment modalities have been employed including dietary modifications, pharmacological agents directed at various targets within the gastrointestinal tract and central nervous system, psychological therapies and more recently, complementary and alternative treatments. Unfortunately, to date, all of these therapies have yielded only marginal results. A variety of emerging therapies are being developed for functional dyspepsia. Most of these therapies are intended to normalize pain perception and gastrointestinal motor and reflex function in this group of patients.

Irritable bowel syndrome (IBS) is a disease entity characterized by recurrent abdominal pain or discomfort associated with altered bowel movement, in which no obvious pathogenetic lesion is identified to explain the symptoms. Postulated pathogenesis for IBS are; motility disorder, visceral sensation abnormalities, complex relationship between brain and gut, relationship to personality, and post-infectious abnormalities in the colonic mucosa. Though many possibilities are presented, diagnostic criteria for IBS are entirely based on the subjective symptoms of the patients. Stress or psychological distress seem to play some roles in the pathogenesis, any of the diagnostic criteria for IBS do not include such aspects. Manning's criteria seem to be the first one to mention the diagnostic criteria. Rome consensus (1988) provoked the attention to IBS among the investigators, with followers like Rome II (1999), and BMW(2000) in Japan. Recently, Rome III criteria was published, which is more clinical oriented.

The role of alcohol use in irritable bowel syndrome (IBS) and dyspepsia is not well understood. We hypothesised that people with psychological distress who drink no alcohol, or excess alcohol, are at increased risk of having IBS or dyspepsia. Valid gastrointestinal (GI) symptom surveys were mailed to randomly selected cohorts of community residents. Associations between IBS, dyspepsia and abdominal pain and alcohol use were assessed using logistic regression adjusted for a Somatic Symptom Checklist score (SSC). A total of 4390 (80%) responded; of these, 10.5% reported IBS, 2% dyspepsia and 22% abdominal pain. Alcohol consumption >7 drinks week(-1) was associated with a greater odds for dyspepsia (OR 2.3; 95% CI:1.1-5.0) and frequent abdominal pain (OR 1.5; 95% CI: 1.1-2.0) but not IBS. However, significant interactions among gender, alcohol use and SSC scores were detected (P < 0.005). In females with a low SSC score, consuming alcohol > or =7 drinks week(-1) increased the odds of IBS compared to drinking alcohol moderately. Alcohol consumption was associated with dyspepsia and abdominal pain. A relationship with IBS was identified when interactions with somatization and gender were appropriately considered. Whether these associations are due to the effects of alcohol on the gut, or a common central mechanism remains to be determined.

Despite the accumulation of efficacy data for cognitive-behavioral treatment of Irritable Bowel Syndrome (IBS), efforts to investigate methods for increasing access to psychological treatments are in their infancy. The current study examined the efficacy of self-administered treatment in comparison to a wait list control. Twenty-eight participants monitored gastrointestinal (GI) symptoms and completed measures of quality of life (QOL) and psychological distress prior to randomized assignment to self-help treatment or wait list. Wait listed participants later received treatment. A 3 month post-treatment follow-up was included. Seven participants completed immediate treatment; nine the wait list. The self-help treatment significantly decreased composite GI symptom scores in comparison to the wait list, but did not lead to significant improvements in QOL or distress. In the entire treated sample, including wait list crossovers, analyses showed significant improvement in abdominal pain, average GI symptoms, and perceived health and well-being. Interpretation of these results should be considered in the context of several limitations, including small sample size, brief baseline symptom monitoring, and high drop out rate. Despite these limitations, this study is an important first step in empirically validating low-cost, self-administered treatments as a first line psychological intervention for IBS.

This study investigates the association of psychological symptoms with the distribution of two serotonin transporter gene (SERT) polymorphisms, located in the promoter region (5-HTTLPR) and in intron 2 (STin2 VNTR), in patients with irritable bowel syndrome (IBS). Participants, 21 men and 117 women, were assessed for mental health history and current psychological distress. A blood sample was used for genotyping. Participants who were homozygous for the short allele of 5-HTTLPR or carried a STin2.9 VNTR allele were significantly more likely to have a history of depression. Participants did not differ by genotype in their history of anxiety or suicidal ideation nor in their current levels of depression, anxiety, or general psychological distress. The results support a biopsychosocial model of IBS in which SERT genotype modifies the risk for depressive episodes. Long term, practitioners may individualize treatment of patients with IBS using genotype as one of the factors.

Irritable bowel syndrome (IBS) affects up to 22% of the general population. Its aetiology remains unclear. Previously reported cross-sectional associations with psychological distress and depression are not fully understood. We hypothesised that psychosocial factors, particularly those associated with somatisation, would act as risk markers for the onset of IBS. We conducted a community-based prospective study of subjects, aged 25-65 years, randomly selected from the registers of three primary care practices. Responses to a detailed questionnaire allowed subjects' IBS status to be classified using a modified version of the Rome II criteria. The questionnaire also included validated psychosocial instruments. Subjects free of IBS at baseline and eligible for follow-up 15 months later formed the cohort for this analysis (n=3732). An adjusted participation rate of 71% (n=2456) was achieved at follow-up. 3.5% (n=86) of subjects developed IBS. After adjustment for age, gender and baseline abdominal pain status, high levels of illness behaviour (odds ratio (OR)=5.2; 95% confidence interval (95% CI) 2.5-11.0), anxiety (OR=2.0; 95% CI 0.98-4.1), sleep problems (OR=1.6; 95% CI 0.8-3.2), and somatic symptoms (OR=1.6; 95% CI 0.8-2.9) were found to be independent predictors of IBS onset. This study has demonstrated that psychosocial factors indicative of the process of somatisation are independent risk markers for the development of IBS in a group of subjects previously free of IBS. Similar relationships are observed in other "functional" disorders, further supporting the hypothesis that they have similar aetiologies.
