Irritable Bowel Syndrome
W. Grant Thompson
- Evidence suggests that several brief psychotherapy sessions or supportive counseling early in the course of the disease lead to greater improvement in symptoms, more satisfaction with care, and quicker return to normal activities.
- Of greater importance [is that] this improvement when compared with that of a control group, is sustained one year after this extra effort.
- Klein concluded that "not a single [pharmaceutical] agent provides conclusive evidence of effectiveness in the global treatment of IBS.

Psychological treatments of Irritable Bowel Syndrome: a review.
Creed and Guthrie
- Psychological treatments are increasingly used in IBS.
- Three ways in which they are effective. 1) relating symptoms to specific stress conditions. 2) help with psychosocial problems. 3) decrease of anxiety and tension.
- Psychological treatments should be reserved for patients who do not respond to first line standard medical treatment.
- Findings [are that] psychotherapy groups significantly improved (in comparison to) controls on abdominal pain, bowel dysfunction, and mental symptoms.
- Differences were apparent at three months and maintained at one year.

Guthrie and Creed et al.
Randomized Controlled Trial of Psychotherapy in Patients With IBS.
- No significant differences between treatment and control groups at start.
- At 3 months scores lower for treatment group on:
- report of abdominal symptoms
- gastroenterologists' ratings of abdominal symptoms
- limiting effect of symptoms on daily functioning
- report of pain on a linear analogue pain scale
- suggestion that improvement in psychological status lead to improvement in bowel symptoms
- greater improvement still after psychotherapy ended.

Impact of Irritable Bowel Syndrome on Quality of Life
Whitehead W.E. C.K. Burnett et al.

Progress Report: Psychological Factors in IBS
Creed and Guthrie
- Studies conclude that psychiatric illness was present in 50% of IBS clinic attenders therefore a definite association [ exists] between functional abdominal pain and psychiatric illness.
- Untreated anxiety and depression impair response to conventional treatments whereas in some patients psychiatric treatment might improve symptoms.
- Some of these patients unless psychiatrically treated, never get better.

Psychiatric Diagnosis, Sexual and Physical Victimization, and Disability in Patients with Irritable Bowel Syndrome or Inflammatory Bowel Disease.
Walker E.A., Gelfand, MD. et al.
- When compared with IBD patients, the IBS patients in this study had significantly higher prevalence rates of lifetime major depression, current panic disorder, somatization disorder, generalized anxiety disorder and agoraphobia, as well as childhood rape and molestation.
- Patients with IBS, despite the absence of serious organic disease, had levels of disability in physical, emotional, family, social and occupational functioning comparable with those of patients with a serious organic gastrointestinal disease...(they) perceived significantly more distress... than patients with IBD.
- These findings suggest that psychological distress plays a fundamental role in the ongoing adjustment that patients make to physical symptoms, and that the treatment of comorbid psychiatric disease in patients with both IBD and IBS is an important goal in the longitudinal care of patients with gastrointestinal symptoms...
- these findings suggest that attention to beliefs about illness and disability, psychosocial factors such as prior history of abuse, and the evaluation and treatment of concurrent psychiatric disorders may be essential factors in the successful treatment of patients with either IBS or IBD.

A Controlled Trial of Psychological Treatment for the Irritable Bowel Syndrome
Guthrie, E. Creed F. et al.
Patients were only selected if their symptoms had not improved with standard medical treatment over the previous three months.
- At three months ( of psychological medical and relaxation treatment) the treatment group showed significantly greater improvement than the controls ( medical treatment only ) on both gastroenterologists', and patients', ratings of diarrhea and abdominal pain, but constipation changed little.
- Good prognostic factors [for psychotherapeutic treatment ] included overt psychiatric symptoms and intermittent pain exacerbated by stress...

- Although there is no rigorous data to support such an approach, treatment of IBS is probably best accomplished by a comprehensive and individualized blend of patient education, support, and psychotherapy, as well as by the pharmacologic treatment of selected symptoms at appropriate times.

Symptom Duration In Patients with Irritable Bowel Syndrome
Lembo T. S. Fullerton. et al.
With the same symptom severity recent IBS patients show less severe psychological symptoms and have a better outcome at 18 month follow up
- Those with short symptom duration and fewer psychological symptoms have a better prognosis than patients with longer histories and associated psychological distress.
- Psychiatric diagnoses such as anxiety, depression and neuroticism are common in patients with chronic abdominal discomfort who seek medical attention. In contrast, patients who have not consulted a physician but who report IBD symptoms have a similar number of psychiatric diagnoses as the general population. ( The implication here is... treat the psychological symptom and the level of seeking relief will decrease.)

Addolorato G. G. Gasbarrini et al.
The substantial lack of difference between the two groups of patients leans in favor of a major role of psychological disturbance in these patients. The close affinity between nerves and mast cells in the gastrointestinal tract can account for a direct influence of the central nervous system on intestinal motility through smooth muscle control, Thus making it conceivable that psychological stress can provoke motility disturbances by a direct release of mast cell mediators.

Irritable Bowel Syndrome and Dysthymia . Is There a Relationship?
Masand. P.S. D.S. Kaplan et al
- Comparing patients seeking treatment for dysthymia and a general clinic population seeking a variety of other treatments the authors found an incidence of IBS symptoms in 59.32% of the experimental group versus 1.85% in the control group.
- Patients with dysthymia were more likely to report symptoms of back pain and weakness, as well as a personal history of bowel disease.
- Future studies need to address whether treatment of primary psychiatric illness leads to an improvement or resolution of the symptoms of IBS.
