Psychosocial aspects of assessment and treatment of irritable bowel syndrome in adults and recurrent abdominal pain in children

Positive psychological well-being: A novel concept for improving symptoms, quality of life, and health behaviors in irritable bowel syndrome

BACKGROUND

Though a growing body of research suggests that greater positive psychological well-being in irritable bowel syndrome (IBS) may be protective, existing brain-gut behavior therapies primarily target negative psychological factors. Little is known about how positive psychological factors in IBS relate to IBS symptoms, health-related quality of life (HRQoL), or adherence to key health behaviors, such as physical activity and diet modification. Accordingly, per the ORBIT model of behavioral treatment development for chronic diseases, we explored potential connections between psychological constructs and IBS symptoms, health behavior engagement (physical activity and dietary modification), and HRQoL in a qualitative study to inform the development of a novel brain-gut behavior therapy.

METHODS

Participants with IBS completed self-report assessments and semi-structured phone interviews about relationships between positive and negative psychological constructs, IBS symptoms, health behavior engagement, and HRQoL.

KEY RESULTS

Participants (n = 23; 57% female) ranged in age from 25 to 79 (mean age = 54). IBS subtypes were similarly represented (IBS-diarrhea [n = 8], IBS-constipation [n = 7], and IBS-mixed [n = 8]). Participants described opposing relationships between positive and negative psychological constructs, IBS symptoms, health behavior engagement, and HRQoL, respectively, such that experiencing positive constructs largely mitigated IBS symptoms, boosted health behavior participation, and improved HRQoL, and negative constructs exacerbated symptoms, reduced health behavior participation, and worsened HRQoL.

CONCLUSIONS AND INFERENCES

Participants with IBS linked greater positive psychological well-being to moderated IBS symptoms and better HRQoL and health behavior participation. An intervention to cultivate greater well-being may be a novel way to mitigate IBS symptoms, boost health behavior participation, and improve HRQoL in IBS.

Positive psychological well-being and clinical characteristics in IBS: A systematic review

OBJECTIVE

Psychological factors (e.g., depression, anxiety) are known to contribute to the development and maintenance of irritable bowel syndrome (IBS). Less is known, however, about the role of positive psychological well-being (PPWB) in IBS. Accordingly, we completed a systematic review of the literature examining relationships between PPWB and clinical characteristics in IBS.

METHOD

A systematic review using search terms related to PPWB and IBS from inception through July 28, 2022, was completed. Quality was assessed with the NIH Quality Assessment Tool. A narrative synthesis of findings, rather than meta-analysis, was completed due to study heterogeneity.

RESULTS

22 articles with a total of 4285 participants with IBS met inclusion criteria. Individuals with IBS had lower levels of PPWB (e.g., resilience, positive affect, self-efficacy, emotion regulation) compared to healthy populations, which in turn was associated with reduced physical and mental health and health-related quality of life (HRQoL). Limited exploration of potential biological mechanisms underlying these relationships has been described.

CONCLUSIONS

PPWB is diminished in individuals with IBS compared to other populations, and greater PPWB is linked to superior physical, psychological, and HRQoL outcomes. Interventions to increase PPWB may have the potential to improve IBS-related outcomes.

Impact of hypnotic safety on disorders of gut-brain interaction: A pilot study

Functional gastrointestinal disorders, i.e., abdominal conditions without identifiable structural etiologies, are seen frequently in primary care and specialty practices. As subtle physiological processes have been identified as potential contributing factors to these functional disorders, these disorders have been recently relabeled, Disorders of Gut-Brain Interaction (DGBI). Moreover, some of these processes, e.g., sympathetic nervous system activity and inflammation, are being increasingly related to psychosocial factors such as situational stress and histories of trauma, abuse, and neglect. As the activity of the autonomic nervous system (ANS) has been long considered to be a contributory factor for DGBI, the present study utilized a theory-driven model based on the Polyvagal Theory to optimize ANS activity for the promotion of healthy digestive activity. Specifically, a hypnotic intervention to increase neuroception of safety was employed with three female college students diagnosed with functional dyspepsia and irritable bowel syndrome in a single-subject design. This intervention was found to be associated with increases in the experience of safe/warm positive affect and decreases in symptoms of functional dyspepsia and irritable bowel syndrome as well as depression and anxiety. The hypnotic intervention for the promotion of a sense of safety is recommended for the treatment of other functional somatic disorders as well as trauma-related conditions. Potential complications related to individuals with prolonged trauma and attachment issues also are reviewed.

Primary Care Evaluation and Management of Gastroenterologic Issues in Women

Gastrointestinal disorders often present to the primary care setting where initial preventive, diagnostic, and treatment strategies are implemented. This article reviews the presentation and diagnosis of common gastrointestinal disorders, including colorectal cancer, irritable bowel syndrome, peptic ulcer disease, gallbladder disorders, inflammatory bowel disease, gastroesophageal reflux, and Barrett's esophagus. We focus on the evaluation and management of these diseases in women.

Possible Involvement of Avoidant Attachment Style in the Relations Between Adult IBS and Reported Separation Anxiety in Childhood

Irritable bowel syndrome (IBS) in adults as well as separation anxiety disorder (SAD) and recurrent abdominal pain (RAP) in childhood are associated with anxiety and somatization. Our aim was to examine possible associations between IBS in adulthood and SAD in childhood. Patients with IBS and healthy subjects completed a demographic questionnaire, the Separation Anxiety Symptom Inventory (SASI), the Somatization Subscale of Symptom Checklist-90-R (SCL-90-R), the Attachment Style Questionnaire, and a retrospective self-report questionnaire regarding RAP. Compared with controls, patients with IBS were characterized by an avoidant attachment style and scored higher on the SCL-90-R scale regarding the tendency to somatization (25.35 ± 7.47 versus16.50 ± 4.40, p < 0.001). More patients with IBS (25% versus 7.5%) reported RAP in childhood, but contrary to prediction, also had significantly lower SASI scores. Adults with IBS were characterized by somatization, insecure attachment style and recalled higher rates of RAP and surprisingly less symptoms of SAD in childhood. Based on these results, an etiological model for IBS is suggested, in which an avoidant attachment style and a tendency to somatization play an important role in the development of IBS.

The impact of abuse and mood on bowel symptoms and health-related quality of life in irritable bowel syndrome (IBS)

BACKGROUND

Irritable bowel syndrome (IBS) is a common abdominal pain disorder without an organic explanation. Abuse histories (physical, sexual, emotional) are prevalent in IBS. While abuse relates to mood disorders (depression and anxiety) also common in IBS, the influence of abuse on gastrointestinal (GI) symptoms and health-related quality of life (HRQOL) and its independence from psychological symptom comorbidity has not been studied.

METHODS

Consecutive GI outpatients completed the ROME III Research Diagnostic Questionnaire and questionnaires on trauma (Life-Stress Questionnaire), mood (Beck Depression/Anxiety Inventories), somatic symptoms (PHQ-12), and HRQOL (SF-36). Current GI symptom severity and bother were assessed using 10-cm Visual Analog Scales.

KEY RESULTS

272 ROME-defined IBS (47.6 ± 0.9 years, 81% female) and 246 non-FGID (51.6 ± 1.0 years, 65% female) subjects participated. IBS patients reported greater rates of physical, sexual, and emotional abuse (p < 0.006 each), and higher depression, anxiety, and somatic symptoms (p < 0.001). Greater bowel symptom bother (7.4 ± 0.2 vs 6.7 ± 0.2, p = 0.040), severity (7.7 ± 0.2 vs 6.5 ± 0.2, p < 0.001), recent symptomatic days (9.8 ± 0.4 vs 8.5 ± 0.3, p = 0.02), and poorer HRQOL (40.9 ± 2.3 vs 55.5 ± 1.7, p < 0.001) were noted in IBS with abuse. Abuse effects were additive, with greater IBS symptom severity and poorer HRQOL noted in cases with multiple forms of abuse. Mediation analyses suggested that abuse effects on GI symptoms and HRQOL were partially mediated by mood.

CONCLUSIONS & INFERENCES

Abuse experiences common among IBS sufferers are associated with reports of greater GI symptoms and poorer HRQOL, particularly in those with multiple forms of abuse; this relationship may be partially mediated by concomitant mood disturbances.

Type, rather than number, of mental and physical comorbidities increases the severity of symptoms in patients with irritable bowel syndrome

BACKGROUND & AIMS

Irritable bowel syndrome (IBS) has significant mental and physical comorbidities. However, little is known about the day-to-day burden these comorbidities place on quality of life (QOL), physical and mental function, distress, and symptoms of patients.

METHODS

We collected cross-sectional data from 175 patients with IBS, which was diagnosed on the basis of Rome III criteria (median age, 41 years; 78% women), who were referred to 2 specialty care clinics. Patients completed psychiatric interviews, a physical comorbidity checklist, the IBS Symptom Severity Scale, the IBS-QOL instrument, the Brief Symptom Inventory, the abdominal pain intensity scale, and the Short Form-12 Health Survey.

RESULTS

Patients with IBS reported an average of 5 comorbidities (1 mental, 4 physical). Subjects with more comorbidities reported worse QOL after adjusting for confounding variables. Multiple linear regression analyses indicated that comorbidity type was more consistently and strongly associated with illness burden indicators than disease counts. Of 10,296 possible physical-mental comorbidity pairs, 6 of the 10 most frequent dyads involved specific conditions (generalized anxiety, depression, back pain, agoraphobia, tension headache, and insomnia). These combinations were consistently associated with greater illness and symptom burdens (QOL, mental and physical function, distress, more severe symptoms of IBS, and pain).

CONCLUSIONS

Comorbidities are common among patients with IBS. They are associated with distress and reduced QOL. Specific comorbidities are associated with more severe symptoms of IBS.

Meditation over medication for irritable bowel syndrome? On exercise and alternative treatments for irritable bowel syndrome

Complimentary alternative treatment regimens are widely used in irritable bowel syndrome (IBS), but the evidence supporting their use varies. For psychological treatment options, such as cognitive behavioral therapy, mindfulness, gut-directed hypnotherapy, and psychodynamic therapy, the evidence supporting their use in IBS patients is strong, but the availability limits their use in clinical practice. Dietary interventions are commonly included in the management of IBS patients, but these are primarily based on studies assessing physiological function in relation to dietary components, and to a lesser degree upon research examining the role of dietary components in the therapeutic management of IBS. Several probiotic products improve a range of symptoms in IBS patients. Physical activity is of benefit for health in general and recent data implicates its usefulness also for IBS patients. Acupuncture does not seem to have an effect beyond placebo in IBS. A beneficial effect of some herbal treatments has been reported.

A cognitive-behavioral treatment for irritable bowel syndrome using interoceptive exposure to visceral sensations

BACKGROUND

Irritable bowel syndrome (IBS) is a chronic and debilitating medical condition with few efficacious pharmacological or psychosocial treatment options available. Evidence suggests that visceral anxiety may be implicated in IBS onset and severity. Thus, cognitive-behavioral treatment (CBT) that targets visceral anxiety may alleviate IBS symptoms.

METHODS

The current study examined the efficacy of a CBT protocol for the treatment of IBS which directly targeted visceral sensations. Participants (N = 110) were randomized to receive 10 sessions of either: (a) CBT with interoceptive exposure (IE) to visceral sensations; (b) stress management (SM); or (c) an attention control (AC), and were assessed at baseline, mid-treatment, post-treatment, and follow-up sessions.

RESULTS

Consistent with hypotheses, the IE group outperformed AC on several indices of outcome, and outperformed SM in some domains. No differences were observed between SM and AC. The results suggest that IE may be a particularly efficacious treatment for IBS.

CONCLUSIONS

Implications for research and clinical practice are discussed.

Pilot study: a randomised, double blind, placebo controlled trial of pancrealipase for the treatment of postprandial irritable bowel syndrome-diarrhoea

OBJECTIVE: To evaluate the efficacy of pancrealipase (PEZ) compared with placebo in the reduction of postprandial irritable bowel syndrome-diarrhoea (IBS-D). DESIGN: An intention to treat, double blind, randomised, crossover trial comparing PEZ to placebo for reduction of postprandial IBS-D. Patients had to recognise at least two different triggering foods, be willing to consume six baseline 'trigger meals' and again blinded with PEZ and placebo. Patients then chose which drug they preferred for another 25 meals. SETTING: Outpatient internal medicine practice clinic. PATIENTS: 255 patients were screened; 83 met the criteria, including 5 years of symptoms, recognised 'food triggers', no other identifiable cause for the symptoms, either a normal colonoscopy or barium enema while symptomatic and able to discontinue all anticholinergic medications. 69 patients were enrolled, 20 withdrew before randomisation, leaving 49 patients: 14 men, 35 women, mean age 52 years (SD 15.3). Over 60% had experienced symptoms for 11-30 years and 16% for more than 40 years. INTERVENTIONS: After completing six baseline meals, patients were randomised in blocks of four to receive either identical PEZ or a placebo for another six meals, and after a washout period of time received the alternative drug. MAIN OUTCOME MEASURES: The primary analysis was number of patients who chose PEZ over placebo for the extended use. RESULTS: Overall, 30/49 (61%) would have chosen PEZ (p=0.078), with first drug preference for PEZ at 0.002. Among the PEZ subgroup, PEZ use compared with placebo, demonstrated improvement in all symptoms (p≤0.001) for cramping, bloating, borborygami, urge to defecate, global pain and decrease stooling with increase in stool firmness. CONCLUSIONS: PEZ was found in a small group of patients to reduce postprandial IBS-D symptoms and deserves further evaluation.

Self-reported and laboratory-based responses to stress in children with recurrent pain and anxiety

OBJECTIVE

To examine heart rate (HR) responses to and coping with stress in children with recurrent abdominal pain (RAP), anxiety, and healthy controls.

METHODS

A clinical sample (children with RAP and children with anxiety) was compared to control children on self-reported and HR responses to stress and a laboratory test of pain tolerance and intensity (cold pressor).

RESULTS

Children in the clinical sample had elevated HRs compared to healthy controls before, during, and after laboratory tasks. Self-reported stress reactivity to social stress was positively correlated with HR at all study time intervals. Secondary control coping with social stress was negatively correlated with HR at most study time intervals. Internalizing symptoms were positively correlated with HR and self-reported stress reactivity.

CONCLUSIONS

Stress reactivity, as reflected in both self-reported and HR responses to laboratory stressors, is related to the presence of both RAP and anxiety in children.

Importance of neural mechanisms in colonic mucosal and muscular dysfunction in adult rats following neonatal colonic irritation

Previous studies have shown that early life trauma induced by maternal separation or colonic irritation leads to hypersensitivity to colorectal distension in adulthood. We tested the hypothesis that repetitive colorectal distension in neonates leads to abnormalities in colonic permeability and smooth muscle function in the adult rat. In neonatal rats, repetitive colorectal distension was performed on days 8, 10, and 12. As adults, stool consistency was graded from 0 (formed stool) to 3 (liquid stool). Colonic tissue was isolated for histology and myeloperoxidase levels. The colonic mucosa was placed in modified Ussing chambers for measurements of permeability and short-circuit current responses to forskolin, electrical field stimulation, and carbachol. Segments of colonic musculature were placed in organ baths and contractile response to potassium chloride, electrical field stimulation, and carbachol were determined. In adult rats that experienced neonatal colonic irritation, no significant changes in colonic histology or myeloperoxidase activity were observed; however, stool consistency scores were increased. Mucosal permeability, measured as an increase in basal conductance, was significantly increased but no changes in short-circuit current responses were observed. In adulthood, rats that underwent colorectal distension as neonates exhibited an elevated smooth muscle contractile response to potassium chloride, but no changes in response to electrical field stimulation or carbachol. In summary, neonatal colonic irritation, shown previously to produce colonic hypersensitivity, leads to significant alterations in colonic mucosal and smooth muscle function characterized by loose stools, increased mucosal permeability, and increased smooth muscle contractility in the absence of colon inflammation in adulthood.

Frequency and severity of the symptoms of irritable bowel syndrome across the anxiety disorders and depression

High rates of irritable bowel syndrome (IBS) symptoms have been reported in individuals diagnosed with anxiety and depressive disorders. However, most studies have investigated these relations in a single disorder, rather than a heterogeneous group of patients, thereby not allowing for comparisons across anxiety disorders and depression, or for considering the effects of comorbidity. Thus, the present study investigated the symptoms of IBS in a diverse group of patients (N=357) by administering questionnaires and a diagnostic interview. A high frequency of IBS symptoms was found in patients with panic disorder, generalized anxiety disorder, and major depressive disorder. However, the frequency of IBS symptoms in patients with social anxiety disorder, specific phobia, and obsessive-compulsive disorder was comparable to rates found in community samples. In addition, anxiety sensitivity and illness attitudes and intrusiveness were predictive of elevated IBS symptomatology. Together, these findings emphasize the role physiological symptoms of anxiety and worry in the co-occurrence of the anxiety disorders and IBS.

Psychological treatments for the management of irritable bowel syndrome

BACKGROUND

No consensus exists on the optimal treatment for irritable bowel syndrome (IBS). Psychological treatments are increasingly advocated but their effectiveness is unclear.

OBJECTIVES

To evaluate the efficacy of psychological interventions for the treatment of irritable bowel syndrome.

SEARCH STRATEGY

A computer assisted search of MEDLINE, EMBASE, PsychInfo, CINAHL, Web of Science, The Cochrane Library and Google Scholar was performed for the years 1966-2008. Local databases were searched in Europe.

SELECTION CRITERIA

Randomised trials comparing single psychological interventions with either usual care or mock interventions in patients over 16 years of age. No language criterion was applied.

DATA COLLECTION AND ANALYSIS

The search identified 25 studies that fulfilled the inclusion criteria. The relative risk (RR), risk difference (RD), number needed to treat (NNT) and standardized mean difference (SMD) along with 95% confidence intervals were calculated using a random effects model for each outcome.

MAIN RESULTS

Psychological interventions as a group The SMD for symptom score improvement at 2 and 3 months was 0.97 (95% CI 0.29 to 1.65) and 0.62 (95% CI 0.45 to 0.79) respectively compared to usual care. Against placebo, the SMDs were 0.71 (95% CI 0.08 to 1.33) and -0.17 (95% CI -0.45 to 0.11) respectively. For improvement of abdominal pain, the SMDs at 2 and 3 months were 0.54 (95%CI 0.10 to 0.98) and 0.26 (95% CI 0.07 to 0.45) compared to usual care. The SMD from placebo at 3 months was 0.31 (95% CI -0.16 to 0.79). For improvement in quality of life, the SMD from usual care at 2 and 3 months was 0.47 (95%CI 0.11 to 0.84) and 0.31 (95%CI -0.16 to 0.77) respectively. Cognitive behavioural therapy The SMD for symptom score improvement at 2 and 3 months was 0.75 (95% CI -0.20 to 1.70) and 0.58 (95% CI 0.36 to 0.79) respectively compared to usual care. Against placebo, the SMDs were 0.68 (95% CI -0.01 to 1.36) and -0.17 (95% CI -0.45 to 0.11) respectively. For improvement of abdominal pain, the SMDs at 2 and 3 months were 0.45 (95% CI 0.00 to 0.91) and 0.22 (95% CI -0.04 to -0.49) compared to usual care. Against placebo the SMD at 3 months was 0.33 (95% CI -0.16 to 0.82). For improvement in quality of life, the SMDs at 2 and 3 months compared to usual care were 0.44 (95% CI 0.04 to 0.85) and 0.92 (95% CI 0.07 to 1.77) respectively.Interpersonal psychotherapy The RR for adequate relief of symptoms was 2.02 (95% CI 1.13 to 3.62), RD 0.30 (95% CI 0.13 to 0.46), NNT 4 for comparison with care as usual. The SMD for improvement of symptom score was 0.35 (95% CI -0.75 to 0.05) compared with usual care. Relaxation/Stress management The SMD in symptom score improvement at 2 months was 0.50 (95%CI 0.02 to 0.98) compared with usual care. The SMD in improvement of abdominal pain at 3 months was 0.02 (95%CI -0.56 to 0.61) compared with usual care. Long term results Very few long term follow-up results were available. There was no convincing evidence that treatment effects were sustained following completion of treatment for any treatment modality.

AUTHORS' CONCLUSIONS

Psychological interventions may be slightly superior to usual care or waiting list control conditions at the end of treatment although the clinical significance of this is debatable. Except for a single study, these therapies are not superior to placebo and the sustainability of their effect is questionable. The meta-analysis was significantly limited by issues of validity, heterogeneity, small sample size and outcome definition. Future research should adhere to current recommendations for IBS treatment trials and should focus on the long-term effects of treatment.

Irritable bowel syndrome and dyspepsia among women veterans: prevalence and association with psychological distress

BACKGROUND

The burden of functional GI disorders and their associations with psychological distress in women veterans is unclear.

AIM

To examine 1-year prevalence of irritable bowel syndrome (IBS) and dyspepsia symptoms and their associations with anxiety, depression and post-traumatic stress disorder (PTSD) among women veterans receiving primary care at a Veteran Affairs Medical Center Women's Clinic.

METHODS

Irritable bowel syndrome, dyspepsia and psychological distress were assessed using the validated self-administered Bowel Disorder Questionnaire, the Beck Depression and Anxiety Inventories, as well as the Mississippi Scale for Combat-Related Post-Traumatic Stress Disorder Questionnaire.

RESULTS

We enrolled 248 women (84% participation rate). Ninety-three (38%) reported IBS and 51 (21%) dyspepsia symptoms. Women with IBS and dyspepsia reported higher mean scores of anxiety (IBS: 24 vs. 12, P < 0.0005 and dyspepsia: 26 vs. 12, P < 0.0005), depression (IBS: 22 vs. 11, P = 0.0005 and dyspepsia: 23 vs. 11, P < 0.0005) and PTSD (IBS: 87 vs. 69, P < 0.001 and dyspepsia: 86 vs. 69, P < 0.0005). Age- and ethnicity-adjusted logistic regression analyses showed a 3- to 46-fold increase in odds of IBS and dyspepsia among women with anxiety, depression or PTSD.

CONCLUSION

Women veterans have high prevalence of IBS and dyspepsia symptoms, both of which are highly associated with presence of depression, anxiety and PTSD.

Hypnotherapy in child psychiatry: the state of the art

Children are more easily hypnotized than adults, and hypnotherapy as a method responds to the general developmental needs of children by addressing their ability for fantasy and imagination. Hypnotherapy and self-hypnosis are tools with which to assess and develop protective factors, and enhance positive adjustment. Meta-analyses and overviews have demonstrated the effect of hypnotherapy in paediatric disorders like asthma, chronic and acute pain, and in procedure-related distress in cancer patients. We wanted to examine the use and benefits of hypnotherapy when applied to child psychiatric disorders. A review of a literature search from PubMed, PsychINFO and the Cochrane databases revealed 60 publications, mostly case reports based on 2-60 cases, addressing the use of hypnotherapy in various child psychiatric conditions. Findings indicate that hypnotherapy may be useful for a wide range of disorders and problems, and may be particularly valuable in the treatment of anxiety disorders and trauma-related conditions. In conclusion, knowledge of hypnosis is useful in clinical practice and hypnotherapy may play an important role as an adjunctive therapy in cognitive-behavioural treatment and family therapy. Additional qualitative and quantitative studies are needed to assess the place for hypnosis/hypnotherapy in child psychiatry.

A controlled evaluation of group cognitive therapy in the treatment of irritable bowel syndrome

We randomized, at two sites, 210 patients with Rome II diagnosed irritable bowel syndrome (IBS), of at least moderate severity, to one of three conditions: group-based cognitive therapy (CT; n=120), psychoeducational support groups (n=46) as an active control, or intensive symptom and daily stress monitoring (n=44). One hundred eighty-eight participants completed the initial treatment. Those in symptom monitoring were then crossed over to CT. For an intent to treat analysis on a composite GI symptom measure derived from daily symptom diaries, both CT and the psychoeducational support groups were significantly more improved than those in the intensive symptom monitoring condition, but the CT and psychoeducational support group did not differ. Among treatment completers on the same composite measure of GI symptoms, again, both CT and psychoeducational support groups were statistically superior to symptom monitoring but did not differ on the symptom composite, or on any other measure. On individual IBS symptoms, both CT and psychoeducational support were statistically superior to symptom monitoring on reductions in abdominal pain and tenderness and for flatulence. Patient global ratings at the end of treatment showed the two active conditions statistically superior to symptom monitoring on change in Bowel Regularity, with CT superior to symptom monitoring on reduction in overall pain and in improvement in sense of well-being. Three-month follow-up data on 175 patients revealed maintenance of significant improvement or continued significant improvement on all IBS symptoms, including the McGill Pain Questionnaire. Group CT and psychoeducational support groups continued not to differ on any measure. We thus conclude that group CT is not superior to an attention placebo control condition.

Recurrent Abdominal Pain, Medical Intervention, and Biofeedback: What Happened to the Biopsychosocial Model?

Recurrent abdominal pain (RAP) is a significant and common problem among pediatric populations. Based on results from randomized controlled trials there are no established efficacious treatments for this disorder. Biofeedback (BFB) and other psychological treatments offer logically appealing alternatives or adjuncts to medical interventions and there is some evidence to support their use. This paper presents a typical case of RAP that exemplifies how the lack of integration of the biopsychosocial model may result in less than optimal treatment. Specifically, it demonstrates that the patient was exposed to potentially risky treatments that lack evidence to support their use and were not beneficial. Although there was evidence of psychological involvement early in the treatment, this was only attended to following numerous medical trials and exploratory surgery over three years. The patient was finally referred for BFB and during a course of seven sessions over five months that variously included heart rate variability and skin temperature feedback along with extensive home practice of paced breathing and hand warming the patient achieved significant symptom reduction and improved coping abilities. This case vividly illustrates the need for multidisciplinary collaboration and full implementation and integration of the biopsychosocial model of health and illness.

Prediction of treatment outcome among patients with irritable bowel syndrome treated with group cognitive therapy

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.

A randomized trial of yoga for adolescents with irritable bowel syndrome

BACKGROUND

Adolescents with irritable bowel syndrome (IBS) frequently experience interference with everyday activities. Mind-body approaches such as yoga have been recommended as interventions for patients with IBS. Despite promising results among adult samples, there have been limited studies exploring the efficacy of yoga with pediatric patients.

OBJECTIVE

To conduct a preliminary randomized study of yoga as treatment for adolescents with IBS.

METHODS

Twenty-five adolescents aged 11 to 18 years with IBS were randomly assigned to either a yoga or wait list control group. Before the intervention, both groups completed questionnaires assessing gastrointestinal symptoms, pain, functional disability, coping, anxiety and depression. The yoga intervention consisted of a 1 h instructional session, demonstration and practice, followed by four weeks of daily home practice guided by a video. After four weeks, adolescents repeated the baseline questionnaires. The wait list control group then received the yoga intervention and four weeks later completed an additional set of questionnaires.

RESULTS

Adolescents in the yoga group reported lower levels of functional disability, less use of emotion-focused avoidance and lower anxiety following the intervention than adolescents in the control group. When the pre- and postintervention data for the two groups were combined, adolescents had significantly lower scores for gastrointestinal symptoms and emotion-focused avoidance following the yoga intervention. Adolescents found the yoga to be helpful and indicated they would continue to use it to manage their IBS.

CONCLUSIONS

Yoga holds promise as an intervention for adolescents with IBS.

A comparison of the clinical, demographic and psychiatric profiles among patients with erosive and non-erosive reflux disease in a multi-ethnic Asian country

AIM: To examine the clinical spectrum of gastroesophageal reflux disease (GERD) and compare erosive (ERD) with non-erosive (NERD) in terms of clinical, demographic and psychiatric profiles.

METHODS: Patients with reflux symptoms were enrolled and stratified to NERD and ERD after endoscopy (LA classification). Patients with ERD presenting with dyspepsia were included. Patients on proton pump inhibitors (PPI) or H₂ receptor antagonists before endoscopy were excluded. Demographic data, Helicobacter pylori (H pylori) status and presence of minor psychiatric morbidity (based on General Health Questionnaire-28) were analyzed.

RESULTS: Among 690 patients screened, 533 were eligible for analysis (male to female ratio: 3:2; Chinese: 75.4%; Malay: 9.8%; Indian: 14.8%). Clinical spectrum of GERD: N: 40.5%; A: 46%; B: 9.2%; C: 2.1%; D: 0.6%; Barrett’s esophagus: 1.7%. Compared to patients with NERD, patients with ERD were significantly older (45 vs 39.4 years), more likely to be male (64.4% vs 53.7%), tended to smoke (19.6% vs 9.7%), less likely to have minor psychiatric morbidity (26.4 vs 46.7%) and were more likely to respond to PPI (79.7 vs 66.8%). There was also a trend towards a higher BMI (24.5 vs 23.5). Race, alcohol consumption and H pylori status were not significant. On multivariate analysis, age and presence of minor psychiatric morbidity remained with significant differences.

CONCLUSION: The majority of patients who have typical symptoms of GERD have NERD or mild erosive reflux disease. Compared to patients with erosive reflux disease, patients with NERD were younger and had a higher prevalence of minor psychiatric morbidity.

Testing the sequential model of pain processing in irritable bowel syndrome: a structural equation modeling analysis

Pain, the cardinal feature of irritable bowel syndrome (IBS), is a multidimensional phenomenon with sensory and affective dimensions. Price's pain processing model was used to delineate four a priori sequentially related stages (pain sensation intensity, immediate pain unpleasantness, long-term suffering, and pain-related behavior). Although prior research with both healthy individuals and somatic pain patients supports the model in general, its applicability to IBS is unclear. Our goal was to extend the scope of the sequential model and test its fundamental tenets using structural equation modeling (SEM) with data obtained from 168 Rome II diagnosed IBS patients (19% male, 81% female). A secondary goal was to assess the relationship between a set of contextual factors associated with IBS (age, gender, trait anxiety) and the four pain stages. Results were consistent with a successive order of pain processing such that the pain sensation directly impacts pain unpleasantness, which, in turn, leads to suffering and illness behaviors. However, contrary to a model with strictly successive stages, pain sensation had independent effects on illness behaviors over and above pain affect. The effect of anxiety on illness behavior was mediated by suffering, while psychopathology directly influenced pain sensation and pain unpleasantness but not later stages. Age was related to pain sensation and illness behaviors but not pain affect. Gender tended to be more strongly associated with more distal pain stages (e.g., pain affect) vis-a-vis its effects on pain sensation. These data are generally supportive of a four-stage pain processing model.

Psychological treatments for irritable bowel syndrome: a systematic review and meta-analysis

This study conducted a systematic review to assess the quality of existing literature on psychological treatments for irritable bowel syndrome and to quantify the evidence for their efficacy. Three independent reviewers (2 from England, 1 from the United States) coded the quality of 32 studies, 17 of which provided data suitable for meta-analysis. Meta-analysis of efficacy data (50% reduction of symptoms) gave an odds ratio of 12 (95% confidence interval = 5.56-25.96) and a number needed to treat of 2. Psychological treatments are, as a class of interventions, effective in reducing symptoms compared with a pooled group of control conditions. Questions regarding the relative superiority of specific psychological treatments and influence of active versus nonspecific treatment effects remain unanswered.

A randomized controlled trial of a cognitive-behavioral family intervention for pediatric recurrent abdominal pain

OBJECTIVE

To investigate whether the combination of standard medical care (SMC) and short-term cognitive-behavioral family treatment (CBT) in the treatment of recurrent abdominal pain (RAP) was more effective than SMC alone.

METHODS

Children recently diagnosed with RAP via physician examination were randomized into SMC (n = 29) and SMC plus CBT (n = 40) groups. Outcome measures included multiple dimensions of child and parent reported child pain, somatization, and functional disability, and school absences and physician contacts.

RESULTS

Children and parents participating in the combined SMC + CBT intervention reported significantly less child and parent reported child abdominal pain than children in the SMC intervention immediately following the intervention and up to 1 year following study entry, as well as significantly fewer school absences. Significant differences in functional disability and somatization were not revealed.

CONCLUSIONS

These results, in combination with previous studies, add support to the effectiveness of CBT intervention in reducing the sensory aspects of RAP. Results are discussed with respect to the cost-benefit of integrated medical and short-term psychological services.

Psychological mechanisms of medically unexplained symptoms: an integrative conceptual model

Theories of medically unexplained illness based on the concepts of dissociation, conversion, and somatization are summarized. Evidence cited in support of these theories is described and the conceptual strengths and shortcomings of each approach are considered. It is argued that each of these approaches adds to the understanding of unexplained illness but that none is able to provide a comprehensive explanation of the phenomenon. An integrative conceptual model of unexplained illness based on cognitive psychological principles is then presented. This model attempts to combine existing theoretical approaches within a single explanatory framework, extending previous theory by explaining how compelling symptoms can exist in the absence of organic pathology. The clinical and empirical implications of the model are then considered.

Citalopram treatment of pediatric recurrent abdominal pain and comorbid internalizing disorders: an exploratory study

OBJECTIVE

To assess the potential efficacy, tolerability, and safety of citalopram in the treatment of functional pediatric recurrent abdominal pain and comorbid internalizing disorders.

METHOD

Twenty-five clinically referred children and adolescents with recurrent abdominal pain aged 7 to 18 years, inclusive, participated in a 12-week, flexible-dose, open-label trial of citalopram. Primary outcome measure was the Clinical Global Impression Scale-Improvement, with responders defined by ratings of 1 (very much improved) or 2 (much improved). Secondary measures included self- and parent reports of abdominal pain, anxiety, depression, other somatic symptoms, and functional impairment. Side effects were assessed using a standardized checklist. Data were analyzed using an intent-to-treat format and the last observation carried forward procedure.

RESULTS

Twenty-one subjects (84%) were classified as responders (Clinical Global Impression Scale-Improvement score < or =2). Citalopram was generally well tolerated. Four subjects withdrew prematurely, one due to reported visual side effects. Ratings of abdominal pain, anxiety, depression, other somatic symptoms, and functional impairment all improved significantly over the course of the study compared with baseline.

CONCLUSIONS

Citalopram is a promising treatment for functional pediatric recurrent abdominal pain and deserves additional study with a randomized, placebo-controlled clinical trial.

Treatment of functional abdominal pain in childhood with cognitive behavioral strategies

OBJECTIVE

The aim of this study was to assess the efficacy of a cognitive-behavioral approach to the treatment of recurrent abdominal pain caused by childhood functional gastrointestinal disorders (FGIDs).

METHODS

From September 2001 to December 2002, 18 patients (12 male; mean age, 12.1 +/- 4.9 years) with chronic abdominal pain (mean duration, 11.8 +/- 13.3 months) caused by FGIDs were referred to our facility's mind-body institute (MBI). Treatment included guided imagery and progressive relaxation techniques. The mean number of sessions per patient was 4.3 +/- 3.4. Outcomes included change in abdominal pain and quality of life, evaluated by the Pediatric Quality of Life Scale (PedsQL). Follow-up was 10.6 +/- 2.3 months after the last MBI session.

RESULTS

Abdominal pain improved in 89% of patients; weekly pain episodes decreased from 5.5 +/- 0.9 to 2.0 +/- 2.7 (P < 0.05); pain intensity (0 to 3 scale) decreased from 2.7 +/- 0.6 to 0.6 +/- 0.7 (P < 0.04); missed school days/month decreased from 4.6 +/- 1.7 to 1.4 +/- 3.2 (P < 0.05); social activities/week increased from 0.3 +/- 0.6 to 1.3 +/- 0.6 (P < 0.05); physician office contacts/year decreased from 24 +/- 10.2 to 8.7 +/- 13.1 (P = 0.07). PedsQL scores (0 to 100 scale) improved from 55.3 +/- 11.9 to 80.0 +/- 10.7 (P < 0.03).

CONCLUSIONS

Guided imagery and progressive relaxation can safely and effectively reduce chronic abdominal pain in children with FGIDs. This treatment also improved social functioning and school attendance.

Parent and Child Psychological Factors in Pediatric Syncope and Other Somatic Symptoms

The authors examined associations among parental and child adjustment, child syncope, somatic, and school problems. Participants were children (N = 56) ages 7-18 years with syncope. Measures included syncope severity, parental distress, and children's internalizing symptoms. For children diagnosed negative for neurocardiogenic syncope (NCS), their fathers' and their own psychological symptoms were positively associated with the severity of syncope, whereas their mothers' functioning was negatively associated with the severity of syncope. Also, for the negative NCS group, fathers' psychological functioning was associated with children's nonsyncope somatic complaints but not with their school problems. For the positive NCS group, few significant father-child associations were found, but several significant positive associations were revealed between mothers' psychological symptoms and their children's syncope as well as somatic and school problems.

The Visceral Sensitivity Index: development and validation of a gastrointestinal symptom-specific anxiety scale

BACKGROUND

Anxiety related to gastrointestinal sensations, symptoms or the contexts in which these may occur is thought to play a significant role in the pathophysiology as well as in the health outcomes of patients with irritable bowel syndrome.

AIM

To develop a valid and reliable psychometric instrument that measures gastrointestinal symptom-specific anxiety.

METHODS

External and internal expert panels as well as a patient focus group evaluated a large pool of potential item stems gathered from the psychological and gastrointestinal literature. Potential scale items were then administered to 96 patients diagnosed with irritable bowel syndrome along with a set of validating questionnaires. Final item selection was based upon rigorous empirical criteria and the psychometric properties of the final scale were examined.

RESULTS

A final unidimensional 15-item scale, the Visceral Sensitivity Index, demonstrated excellent reliability as well as good content, convergent, divergent and predictive validity.

CONCLUSIONS

The findings suggest that the Visceral Sensitivity Index is a reliable, valid measure of gastrointestinal symptom-specific anxiety that may be useful for clinical assessment, treatment outcome studies, and mechanistic studies of the role of symptom-related anxiety in patients with irritable bowel syndrome.

The role of childhood abuse in Axis I and Axis II psychiatric disorders and medical disorders of unknown origin among irritable bowel syndrome patients

OBJECTIVE

High rates of early abuse and psychopathology are commonly reported among treatment-seeking patients with irritable bowel syndrome (IBS). The purpose of this study is to further explore the relations among IBS, early abuse, Axes I and II psychopathology, and other medically unexplained disorders.

METHODS

One hundred and ninety-six IBS patients seeking nondrug treatment for their symptoms were characterized in terms of their gastrointestinal (GI) status, psychiatric status (Axis I and Axis II), early abuse status, and the presence of other functional disorders. Patients were divided into two groups based on early abuse status.

RESULTS AND CONCLUSION

No significant differences emerged between abused and nonabused groups on either the presence of Axis II disorders or other functional health conditions, although there were high levels of both in the IBS population. Patients with a history of abuse were significantly more likely to meet criteria for an Axis I disorder, especially substance abuse disorders, dysthymia, and generalized anxiety disorder.
