Psychological comorbidity and complexity of gastrointestinal symptoms in clinically diagnosed irritable bowel syndrome patients

Background and Aim:  The prevalence of psychological disorders is high in patients with irritable bowel syndrome (IBS) but their role in symptom reporting is uncertain. It is thus interesting whether the number of functional gastrointestinal disorders (FGID) determines the load of psychological comorbidity. The Rome III criteria have not been used to evaluate such a relationship as yet. Moreover, not many studies have examined the sensitivity of the Rome III criteria in detecting IBS. Our aims were therefore: (i) to determine whether those IBS participants with more FGID had a tendency to greater psychological comorbidity than those with fewer FGID; and (ii) to assess the performance of the Rome III criteria in detecting IBS versus the diagnosis of the gastroenterologist.
Methods:  A cross-sectional survey of 32 consecutive outpatients with clinically diagnosed IBS was performed. The Hospital Anxiety and Depression Scale (HADS), the Short Form 12 Health Survey (SF-12), and the Rome III criteria questionnaire (BDQ-6) were administered. Multiple linear regression was conducted to detect associations among FGID, anxiety, depression and quality of life.
Results:  Overall, 50% of participants were anxious and 12% were depressed. Forty-four percent of participants had >two FGID; however, the number of FGID did not correlate with scores for anxiety, depression or quality of life. Amazingly, only 50% (CI: 33–67) of participants clinically diagnosed with IBS met Rome III criteria for IBS.
Conclusion:  Contrary to our expectations, a greater load of FGID did not correlate with a greater load of psychological comorbidity. Surprisingly, the Rome III criteria detected only 50% of clinical cases of IBS.     

Concomitant Functional Gastrointestinal Symptoms Influence Psychological Status in Korean Migraine Patients

Background/Aims

Migraine is frequently accompanied by symptoms consistent with functional gastrointestinal disorders (FGIDs). This study evaluated the prevalence of functional gastrointestinal symptoms and assessed the symptoms'' relationship with the concomitant functional symptoms of anxiety, depression, and headache-related disability.

Methods

This prospective study included 109 patients with migraine who were recruited from a headache clinic at a teaching hospital. The participants completed a self-administered survey that collected information on headache characteristics, functional gastrointestinal symptoms (using Rome III criteria to classify FGID), anxiety, depression, and headache-related disability.

Results

In total, 71% of patients met the Rome III criteria for at least one FGID. In patients with FGID, irritable bowel syndrome was the most common symptom (40.4%), followed by nausea and vomiting syndrome (24.8%) and functional dyspepsia (23.9%). Depression and anxiety scores were significantly higher in patients meeting the criteria for any FGID. The number of the symptoms consistent with FGID in individual patients correlated positively with depression and anxiety.

Conclusions

FGID symptoms defined by the Rome III criteria are highly prevalent in migraine. These symptoms correlate with psychological comorbidities, such as depression and anxiety.     

Functional gastrointestinal disorders and mood disorders in patients with inactive inflammatory bowel disease: prevalence and impact on health

BACKGROUND: Symptoms of functional gastrointestinal disorders (FGID) associated with mood disorders (MD), such as depression and anxiety, occur in some patients with quiescent inflammatory bowel disease (IBD) and could be caused by changes in gut motility, visceral hypersensitivity, or psychological dysfunction. We assessed the prevalence of FGID symptoms and mood disorders in ambulatory patients with quiescent IBD and examined their impact on health-related quality of life (HRQOL) and use of health resources. METHODS: Consecutive ambulatory patients with IBD completed a survey of Rome II criteria for FGID, the Hospital Anxiety and Depression Survey, HRQOL indices, and health resource utilization. Logistic and linear regression analyses tested for predictors of FGID and HRQOL. RESULTS: Of 361 patients surveyed, 149 (44 ulcerative colitis [UC] and 105 Crohn's disease [CD]) had inactive IBD during the previous 12 months. Symptoms of at least 1 FGID occurred in 81.9%. Functional anorectal disorders were the most prevalent (53.7%) followed by functional bowel disorders (51.7%), and both were of greater prevalence than in the Canadian population (41.6% and 22.6%, respectively). Irritable bowel syndrome symptoms were more common in inactive CD than in UC (26% versus 9.1%, P = .01) and functional constipation was more common in inactive UC than in CD (26.2% versus 5.8%, P < .01). MD occurred in 27.3% of UC and 31.3% of CD patients. Age > or =40 years and anxiety independently predicted an FGID. Both FGID symptoms and MD were associated with impaired HRQOL and increased use of health services. CONCLUSIONS: Many patients with inactive IBD have symptoms compatible with FGID. Both FGID-like symptoms and MD are associated with impaired HRQOL and increased health resource utilization. Recognition and treatment of FGID and MD could potentially improve daily functioning of IBD patients.     

Extra Digestive Manifestations of Irritable Bowel Syndrome: Intolerance to Drugs?

Patients with IBS frequently complain of medication side effects. The goals of this study were to assess the prevalence of drug intolerance as an extra GI manifestation in patients with IBS and to verify the association between drug intolerance and psychological comorbidity. Female patients followed in a tertiary care center completed questionnaires assessing the presence of drug intolerance as well as somatic and psychological extra GI conditions. IBS patients (Rome II criteria; n = 71) were compared to inflammatory bowel disease patients (IBD; n = 96) or to healthy controls (HC; n = 67). The relationship to psychological comorbidity was verified in two different paradigms: (1) by looking at the statistical correlation between drug intolerance and the psychological extra GI symptoms in our IBS patients, and (2) by comparing in a meta-analysis the side effects to placebo (the nocebo effect is presumably increased due to hypervigilance or amplification in psychological disorders) in IBS patients or in patients with comparable medical conditions included in various drug trials approved by Health Canada. Our results show that prevalence of drug intolerance was significantly more elevated in IBS (41% patients) than in HC (7%) or in IBD (27%); somatic and psychological extra GI symptoms were also markedly increased in IBS. In addition, drug intolerance in our IBS patients was significantly associated with somatic comorbidities such as fatigue or multiple symptoms (P < 0.001), but not with psychological factors such as depression, anxiety, mood instability, or sleep disorder. A meta-analysis revealed that the nocebo effect was not different in patients with IBS than in control patients. In conclusion, drug intolerance is a frequent extra GI manifestation of IBS that is not associated with psychological comorbidity; thus, a somatic origin must be explored.     

Comorbidity and use of health-care services among irritable bowel syndrome sufferers

Objective. Patients suffering from irritable bowel syndrome (IBS) have more somatic and psychiatric comorbidity and use more health-care services for comorbid conditions than do other patients. Little is known about the frequency of comorbid symptoms among IBS sufferers in the general population and their influence on use of health-care facilities. The objective of this study was to compare the frequency of somatic and psychiatric symptoms between IBS sufferers and controls in the general population, and to study how comorbidity rates are distributed among consulters and non-consulters and how they predict the use of health care-services. Material and methods. By means of a questionnaire sent to 5000 randomly selected adults IBS was identified according to the Rome II criteria. The questionnaire also covered upper GI symptoms, non-GI somatic symptoms, depression and anxiety. A logistic regression analysis with 26 variables was carried out to determine the independent predictors of health-care seeking for GI and non-GI complaints. Results. The response rate was 73% and prevalence of IBS 5.1% (95% CI 4.4–5.8%). Dyspeptic symptoms, somatic extra-GI symptoms and psychiatric symptoms were reported by 45%, 69% and 51% of IBS sufferers, respectively, and 6%, 35% and 27%, of controls, respectively. Visiting a physician because of GI complaints was associated with disturbing abdominal symptoms, but not with depression or anxiety. Of the present GI conditions, only dyspeptic symptoms were associated with an increased consultation rate also for non-GI complaints. Conclusions. In the general population, both IBS consulters and non-consulters demonstrate high rates of comorbidity. Seeking health care for abdominal complaints is associated with abdominal symptoms rather than psychiatric comorbidity.     

Epidemiology and health care seeking in the functional GI disorders: a population-based study

OBJECTIVES: Functional GI disorders (FGIDs) are common in clinical practice, but little is known about the epidemiology of these disorders in the general population. We aimed to determine the prevalence, association with psychological morbidity, and health care seeking behavior of FGIDs in the population. METHODS: A random sample of subjects (n = 4500) aged > or = 18 yr and representative of the Australian population were mailed a validated questionnaire. For these subjects we measured all Rome I GI symptoms and physician visits over the past 12 months, as well as neuroticism, anxiety, depression, and somatic distress. RESULTS: The response rate for the study was 72%. The prevalence of any FGID was 34.6%, and 62.1% of these subjects had consulted a physician. There was considerable overlap of the FGIDs (19.2% had more than two disorders). Independent predictors for an FGID diagnosis were neuroticism, somatic distress, anxiety, bowel habit disturbance, abdominal pain frequency, and increasing age. However, psychological morbidity did not independently discriminate between consulters and nonconsulters with an FGID. CONCLUSIONS: More than one third of the general population have one or more FGIDs. There seems to be a modest link between psychological morbidity and FGIDs, although other unknown factors seem to be more important in explaining health care seeking for these disorders.     

Anxiety and depression in various functional gastrointestinal disorders: Do differences exist?

OBJECTIVE: To examine the differences in the prevalence and severity of anxiety and depression in patients with functional dyspepsia (FD), nonerosive reflux disease (NERD), irritable bowel syndrome (IBS) and healthy controls. METHODS: Consecutive patients undergoing an index endoscopic examination for various symptoms were interviewed. All the three functional gastrointestinal disorders (FGIDs) were diagnosed according to the Rome III criteria. Anxiety and depression were diagnosed using a locally validated version of the hospital anxiety and depression scale. RESULTS: A total of 248 patients were recruited (62 in FD, NERD, IBS and control groups each) with no differences in the basic characteristics. There was a higher prevalence of anxiety and depression in FD, NERD and IBS groups than that in the control group (43.5%, 45.2% and 67.7% vs 14.5%, P < 0.001; and 22.6%, 33.9% and 38.7% vs 6.5%, P < 0.0001). Using the cut‐off score (> 8) for anxiety or depression, IBS patients had a higher rate of anxiety than FD (P = 0.01) and NERD (P = 0.02), while no significant differences in depression rates were observed among all three groups. CONLUSION: Anxiety is more common in patients with IBS than in those with FD and NERD, indicating a possible causal link in the former.     

Epidemiology of the functional gastrointestinal disorders diagnosed according to Rome II criteria: an Australian population-based study

BACKGROUND: Population-based studies of the prevalence of all functional gastrointestinal disorders (FGID) using the Rome II criteria are lacking. It is also not certain whether subjects who meet the Rome II criteria for an FGID are different in terms of demographic and psychological characteristics from those subjects meeting exclusively the more restrictive Rome I criteria. AIM: To determine whether using the more restrictive Rome I criteria would result in a more biologically determined group of FGID than when the Rome II is applied. METHODS: Subjects included individuals aged 18 years and older (n = 1,225) from the Penrith population who were initially surveyed with the Penrith District Health Survey in 1997. Subjects were sent a self-report questionnaire that contained items on gastrointestinal symptoms applying the Rome II criteria. Subjects were also assessed on psychological and personality factors and on physical and mental functioning. RESULTS: A total of 36.1% (n = 275) of respondents was diagnosed with an FGID according to Rome II criteria. The five most prevalent FGID were functional heartburn (10.4%), irritable bowel syndrome (8.9%), functional incontinence (7.6%), proctalgia fugax (6.5%) and functional chest pain (5.1%). Subjects meeting Rome II only criteria for FGID scored significantly higher on measures of psychological caseness and emotionality than Rome I only subjects, and these were independently associated with meeting Rome I only versus Rome II only criteria for FGID. CONCLUSION: The Rome II criteria FGID are common and do not appear to identify a vastly different group of FGID sufferers compared with the earlier Rome I criteria.     

Prevalence of irritable bowel syndrome and its relationship with psychological stress status in Chinese university students

Background and Aims: Although irritable bowel syndrome (IBS) is a common disorder in the West, information on the prevalence of IBS in university students is relatively scant, especially in Asia. The aims of the present study were to investigate the prevalence and pattern of symptoms of IBS and its relationship with psychological stress status in Chinese university students. Methods: Basic demographic data and IBS symptoms were sought using the Rome II criteria and a validated bowel symptom questionnaire. Another questionnaire used related to psychosomatic symptoms of depression and anxiety. Results: In total, 491 of the 530 students in the trial met the selected criteria, which included 241 men. The participants were medical college students (313/491) and non‐medical college students (178/491). The apparent prevalence of IBS was 15.7%, with a prevalence of 14.5% in men and 16.8% in women. The most common symptom was abdominal pain associated with change in the consistency of stool (36.9%), followed by altered stool frequency (16.3%), and abdominal pain relieved by defecation (12.4%), predominantly in women. The self‐reported psychological and psychosomatic symptoms of anxiety (P < 0.001) and depression (P < 0.001) were encountered more frequently in participants with IBS. The depression (P = 0.03) and anxiety measures (P = 0.02) significantly predicted IBS status. Conclusion: The prevalence of IBS in Chinese university students is often compared with university students in developed countries and the general Chinese population. Depression and anxiety could potentially induce IBS. Medical education should be considered when aiming to reduce stress of university students who are susceptible to IBS.     

Comorbidity and use of health-care services among irritable bowel syndrome sufferers

OBJECTIVE: Patients suffering from irritable bowel syndrome (IBS) have more somatic and psychiatric comorbidity and use more health-care services for comorbid conditions than do other patients. Little is known about the frequency of comorbid symptoms among IBS sufferers in the general population and their influence on use of health-care facilities. The objective of this study was to compare the frequency of somatic and psychiatric symptoms between IBS sufferers and controls in the general population, and to study how comorbidity rates are distributed among consulters and non-consulters and how they predict the use of health care-services. MATERIAL AND METHODS: By means of a questionnaire sent to 5000 randomly selected adults IBS was identified according to the Rome II criteria. The questionnaire also covered upper GI symptoms, non-GI somatic symptoms, depression and anxiety. A logistic regression analysis with 26 variables was carried out to determine the independent predictors of health-care seeking for GI and non-GI complaints. RESULTS: The response rate was 73% and prevalence of IBS 5.1% (95% CI 4.4-5.8%). Dyspeptic symptoms, somatic extra-GI symptoms and psychiatric symptoms were reported by 45%, 69% and 51% of IBS sufferers, respectively, and 6%, 35% and 27%, of controls, respectively. Visiting a physician because of GI complaints was associated with disturbing abdominal symptoms, but not with depression or anxiety. Of the present GI conditions, only dyspeptic symptoms were associated with an increased consultation rate also for non-GI complaints. CONCLUSIONS: In the general population, both IBS consulters and non-consulters demonstrate high rates of comorbidity. Seeking health care for abdominal complaints is associated with abdominal symptoms rather than psychiatric comorbidity.     

Psychological features are important predictors of functional gastrointestinal disorders in patients with eating disorders

OBJECTIVE: Gastrointestinal symptoms that occur without evidence of structural gastrointestinal disease are a well-recognized feature of patients with eating disorders (EDs). Despite this, the spectrum and predictors of specific functional gastrointestinal disorders (FGIDs), documented using standardized and validated questionnaires, have received little attention. The aims of the study were to describe the prevalence and type of FGIDs in patients suffering from anorexia nervosa (AN), bulimia nervosa (BN) and eating disorders not otherwise specified (EDNOS), and to determine the relationships between psychological features, eating-disordered attitudes and behaviours, demographic characteristics and the type and number of FGIDs present. MATERIAL AND METHODS: A total of 101 consecutive female patients admitted to an eating disorder unit (AN 44%, BN 22%, EDNOS 34%, mean age 21 years) completed the Rome II modular questionnaire and a range of other validated self-reported questionnaires detailing illness history, psychological features and eating and exercise behaviour. RESULTS: The criteria for at least one FGID were fulfilled by 98% of the sample. The most prevalent FGIDs were irritable bowel syndrome (IBS: 52%), functional heartburn (FH: 51%), functional abdominal bloating (31%), functional constipation (FC: 24%), functional dysphagia (23%) and functional anorectal pain disorder (FAno: 22%); 52% of the sample satisfied the criteria for at least three coexistent FGIDs. Psychological variables (somatization, neuroticism, state and trait anxiety), age and binge eating were significant predictors of specific, and > or =3 coexistent FGIDs. Other disordered eating characteristics, including body mass index, were not predictors. CONCLUSIONS: In patients with EDs, specific psychological traits predict FGID type and the presence of multiple coexistent FGIDs. These findings support the role of specific psychological features as important contributors to certain FGIDs.     

Colonoscopy as an adjunctive method for the diagnosis of irritable bowel syndrome: Focus on pain perception

Background and Aim: Visceral hypersensitivity is an important component of the pathophysiology of irritable bowel syndrome (IBS). In the present study, we investigated differences in pain perception during colonoscopy between IBS patients and non‐IBS patients. We further assessed the sensitivity, specificity, and predictive values of pain scores to diagnose IBS. Methods: Patients who underwent colonoscopy for the evaluation of gastrointestinal symptoms or for screening purposes were included. All patients completed Rome III criteria questionnaires and reported pain scores on 0–100‐mm visual analog scales after colonoscopy. The patients were divided into three groups: (i) IBS; (ii) other functional gastrointestinal disorders (FGID), including functional bloating, functional diarrhea, and functional constipation; and (iii) healthy controls. Results: A total of 217 patients were included. The pain scores (median, interquartile range) of IBS patients (52, 34–71) were higher than those of the healthy controls (22, 12–35) or other FGID patients (18, 10–29) (P < 0.001). Upper gastrointestinal symptoms were observed more often in the IBS group than in the non‐IBS group (83.2% vs 34.5%, P < 0.001). At the pain score level of 31, the sensitivity, specificity, positive predictive value, and negative predictive value for IBS diagnosis were 86.1%, 75.9%, 75.7%, and 86.3%, respectively. Conclusions: The degree of pain perception during colonoscopy was higher in IBS patients than in non‐IBS patients. We concluded that colonoscopy can be useful in identifying IBS patients, with the additional benefit of excluding organic disorders of the lower gastrointestinal tract.     

The impact of an adaptation course on health-related quality of life and functional capacity of patients with inflammatory bowel disease

Abstract

Background: Inflammatory bowel disease (IBD) has a substantial impact on patients health-related quality of life (HRQoL). In this study, we examined the impact of adaptation courses on HRQoL, psychological well-being, depression and number of sick-leave days of IBD patients.

Methods: The study recruited 142 IBD patients attending an adaptation course of 5–12 days. The courses were specially designed for IBD patients and included multidisciplinary information about IBD, peer support, group activities and encouragement for adequate physical exercise. The participants completed the study questionnaire at the beginning and the end of the course and after six and 12 months of follow-up. HRQoL was assessed with the generic 15-dimensional (15D) tool and depression with Beck’s Depression Inventory (BDI). Utilization of health care services and work absenteeism was also assessed. Visual analog scales were used for assessing psychological functioning.

Results: 15D, BDI scores and scores describing psychological well-being were significantly better at the end of the course when compared to baseline (15D 0.82 vs. 0.84, p?p?p?=?.01). No significant change in health care utilization or number of sick-leave days was observed.

Conclusion: Adaptation training appears to have a positive impact on the psychological well-being of IBD patients. Peer support appears to be an important factor.     

Pain Hypersensitivity in Patients with Functional Gastrointestinal Disorders: A Gastrointestinal-Specific Defect or a General Systemic Condition?

Visceral hypersensitivity was shown in patients with functional gastrointestinal disorders (FGID). The mechanisms underlying this sensory dysfunction remain undetermined. The initial hypothesis of a generalized reduction in pain tolerance was rejected by further studies that suggested a normal tolerance to somatic stimuli and led to the generally accepted assumption that pain intolerance is specific and exclusive for visceral stimuli in these patients. We wanted to revisit this theory by examining whether patients with FGID reported perception and tolerance to somatic pain differently from normal subjects and whether the response to somatic pain stimulus was correlated to gastrointestinal symptoms or psychological status or distress. Thirty-three patients with FGID (Rome II criteria)(F/M: 26/7; mean age 48 ± 9.9) and 33 normal controls (F/M: 24/9; mean age 44.1 ± 6.8) were asked to immerse their nondominant hand into 4°C water for as long as possible (maximum 120 sec). Time before appearance of: (1) discomfort, (2) pain, and (3) withdrawing of the hand were noted. The intensity of pain was rated on a visual analog scale from 0 to 100. Self-report questionnaires were used to assess the severity of gastrointestinal symptoms (St-Luc GI index) and the psychological distress (SCL-90) in the patient group. Data are expressed in seconds as mean ± sem. Discomfort sensory thresholds were similar in controls and FGID patients (28 ± 3 and 24 ± 2, respectively; NS) whereas pain and withdrawing were significantly lower in FGID (41 ± 3 and 76 ± 6 sec) than in controls (62 ± 6 and 102 ± 4; P < 0.05). Pain intensity was similar in both groups (64 ± 4 vs 67 ± 3; NS). Female patients showed lower sensory thresholds than male patients and control females (pain thresholds: 39.8 ± 3.4 vs 67.8 ± 16.7 and vs 56.8 ± 8.7; P < 0.05). Sensory thresholds were not different in subgroups of patients with FGID (irritable bowel syndrome and functional dyspepsia). No correlation was shown between sensory thresholds and gastrointestinal index or SCL 90-test. In conclusion, FGID patients showed a threshold to painful somatic stimulus that was lower than in normal subjects. These findings suggest that patients with FGID may have hyperalgesia and low pain tolerance that is not limited to the viscera, but that is part of a systemic general condition.     

Quality of life in inflammatory bowel disease in remission: the impact of IBS-like symptoms and associated psychological factors

OBJECTIVES: Quality of life is reduced in inflammatory bowel disease (IBD). Whether or not this is true in IBD patients in long-standing remission is unclear. Symptoms compatible with irritable bowel syndrome (IBS) are common in IBD patients in remission. The importance of psychological factors in this process is a matter of controversy. METHODS: Forty-three patients with ulcerative colitis (UC) and 40 with Crohn's disease (CD), who had been in remission for at least 1 yr according to laboratory parameters and clinical and endoscopical appearance, were included. These patients completed four different self-administered questionnaires, evaluating GI symptoms, anxiety, depression, and psychological general well-being. The two patient groups were compared with the general population, and within-group comparisons in psychometric scores were made between patients with and without IBS-like symptoms. RESULTS: The psychological well-being in IBD patients in long-standing remission was similar to that of the general population, despite the presence of more severe GI symptoms. CD patients reported more psychosocial dysfunction, reduced well-being, and GI symptoms than UC patients. Thirty-three percent of UC patients and 57% of CD patients had IBS-like symptoms. The group with IBS-like symptoms (both UC and CD) had higher levels of anxiety and depression and more reduced well-being than those without. Anxiety and reduced vitality were found to be independent predictors for IBS-like symptoms in these patients. CONCLUSION: The prevalence of IBS-like symptoms in IBD patients in long-standing remission is two to three times higher than that in the normal population. Psychological factors seem to be of importance in this process. However, as a group IBD patients in remission demonstrate psychological well-being comparable to that of the general population.     

Symptoms of anxiety and depression are independently associated with inflammatory bowel disease-related disability

BackgroundInflammatory bowel disease (IBD) frequently results in disability. The relevance of psychological effects in causing disability, and whether disability occurs similarly in non-Western cohorts is as yet unknown.AimWe assessed the relationship between symptoms of anxiety and depression, quality of life and disability in a Singaporean IBD cohort and their predictors.MethodsCross-sectional study. We assessed consecutive IBD subjects’ IBD-Disability Index (IBD-DI), Hospital Anxiety and Depression Scale (HADS), and IBD questionnaire (IBDQ). Clinical and demographic variables were collected. Non-parametric statistical analyses were performed. Independent predictors of disability were identified through multivariate logistic regression.Results200 consecutive subjects were recruited (males: 69%; median age: 43.8 (±15.4) years; 95 had Crohn’s disease (CD), 105 had ulcerative colitis (UC); median IBD duration: 10.8 (±9.0) years.) 27% of the cohort had anxiety and/or depression, which worsened disability (IBD-DI: −9 (±14) with anxiety vs 6 (±13) without anxiety, P < 0.001; −12 (±16) with depression vs 5 (±13) without depression, P < 0.001). Age at diagnosis, use of prednisolone, stricturing CD and active IBD were significant predictors of disability. IBDQ strongly correlated with IBD-DI(r_s = 0.82, P < 0.01).ConclusionSymptoms of anxiety and depression were common in this Asian cohort of IBD and were strongly associated with IBD-related disability. Recognizing psychological issues contributing to disability in IBD is important to ensure holistic care and appropriate treatment.     

Altered rectal perception in irritable bowel syndrome is associated with symptom severity

BACKGROUND & AIMS: Diverging results exist regarding the connection between altered visceral perception and gastrointestinal (GI) symptoms, as well as the effects of psychological status on visceral sensitivity. We sought to investigate different aspects of rectal perception in irritable bowel syndrome (IBS) and the association with GI and psychological symptoms. METHODS: We included 109 patients with IBS meeting Rome II criteria (77 women; age range, 20-71 years) and 29 healthy controls (21 women; age range, 20-68 years). They underwent rectal balloon distentions determining sensory thresholds for discomfort and pain, the perceived intensity of unpleasantness, and the viscerosomatic referral area. The fifth percentile (thresholds) and 95th percentile (unpleasantness and referral area) in controls were used to define altered perception. Questionnaires were used to assess severity of IBS-related GI symptoms and psychological symptoms. RESULTS: When combining the 3 aspects of perception, 67 patients (61%) had altered rectal perception. These patients, compared with normosensitive patients, more frequently reported moderate or severe pain (73% vs 44%; P < .01), bloating (73% vs 36%; P < .0001), diarrhea (47% vs 21%; P < .01), satiety (39% vs 13%; P < .01), and clinically significant anxiety (31% vs 12%; P < .05). In a multivariate analysis, only pain and bloating remained associated with altered rectal perception. CONCLUSIONS: Altered rectal perception is common in IBS and seems to be one important pathophysiologic factor associated with GI symptom severity in general and pain and bloating in particular. It is not just a reflection of the psychological state of the patient.     

Group counseling psychotherapy for patients with functional gastrointestinal disorders: development of new measures for symptom severity and quality of life

Functional gastrointestinal disorders (FGID) can benefit from various psychological interventions. The main objective here was to define the contribution of a new psychotherapeutic intervention, group counseling psychotherapy, for the management of FGID patients. Secondary aims included validation of new measures for gastrointestinal symptoms and quality of life in patients with FGID. Fifty patients seen in a tertiary care center were included in a program of 10 weekly sessions of 2 hr each. Gastrointestinal symptoms, quality of life, and psychological conditions were measured before and after treatment by quantitative indices and by qualitative self-analysis. Gastrointestinal index and quality-of-life index were significantly (P < 0.02) improved at the end of the psychotherapeutic intervention (from 77.5 ± 4.0 to 63.2 ± 4.3 and from 67.7 ± 3.9 to 54.9 ± 3.9, respectively). In a control group of patients observed for a comparable period of time while waiting for the psychotherapy program, gastrointestinal and quality of life indices remained unchanged. The severity of gastrointestinal symptoms and the quality of life deterioration were highly correlated factors (r = 0.8) at entry into the trial, and their improvement with psychotherapy was also correlated (r = 0.6; P < 0.001). Psychological abnormalities were frequent in these patients (anxiety in 31%, somatization in 29%, depression in 26% of the patients). However, no specific disorder could predict the results of the psychotherapeutic intervention. Over the long term (6–24 months after conclusion of treatment), gastrointestinal status, quality of life, and psychological condition were estimated as improved by 53%, 63%, and 67% of the patients, respectively. The gastrointestinal index and quality of life index we developed were validated to detect the disease and to follow its evolution in response to treatment. In conclusion, group counseling psychotherapy offered a significant contribution for the management, improving gastrointestinal symptoms and quality of life, of FGID patients. New measures for symptom severity and quality of life are available.     

Prevalence of irritable bowel syndrome in young adult Malaysians: a survey among medical students

BACKGROUND AND AIMS: Irritable bowel syndrome (IBS) is a common functional bowel disease in the West. Information on the prevalence of IBS in the Asian population is relatively scanty. The aims of the present study were to determine the prevalence of IBS and to assess the symptom subgroups based on the predominant bowel habit in a young adult population of Asian origin. METHODS: Basic demographic data and symptoms of IBS using the Rome I criteria were sought using a questionnaire administered to all apparently healthy students in a medical school. Other questions asked related to alcohol intake, smoking, chili consumption, dietary fiber intake, and to psychological and psychosomatic symptoms of anxiety, depression, insomnia, headache, and backache. The health-care seeking behavior of the subjects was also analyzed. RESULTS: Of the 610 questionnaires administered, 533 complete responses were received (response rate of 87.4%). The responders comprised 229 men (43.0%) and 304 (57.0%) women with a mean age of 22 +/- 1.8 years. The ethnic distribution was Malays 278 (52.2%), Chinese 179 (33.6%), Indians 46 (8.6%), and others 30 (5.6%). Eighty-four (15.8%) reported symptoms consistent with the diagnosis of IBS, predominantly women. Sixty-five (77.4%) and six (7.1%) were of the constipation-predominant and diarrhea-predominant IBS subgroups, respectively. Thirteen (15.5%) subjects fell into the non-specific IBS subgroup. The self-reported psychological and psychosomatic symptoms of anxiety (P = 0.02), depression (P = 0.002), insomnia (P = 0.006), headache (P = 0.04), and backache (P = 0.006) were encountered more frequently in the subjects with IBS. Only 13.1% of the IBS group had consulted their health-care practitioner, and 20.2% reported self-medication. CONCLUSIONS: Symptoms supportive of the diagnosis of IBS were common among young Malaysians, with a prevalence rate of 15.8%. There were significantly more women with IBS than men. Within the IBS population, the majority (77.4%) was of the constipation-predominant IBS subgroup. A significantly higher prevalence of psychological and psychosomatic symptoms was found in individuals with IBS. Only a minority sought medical advice for their symptoms.     

Evolution of the emotional impact in patients with early inflammatory bowel disease during and after Covid-19 lockdown

BackgroundPatients with inflammatory bowel disease (IBD) are vulnerable to some psychological disorders. Here we describe the psychological impact of a COVID-19 pandemic lockdown in patients with IBD.MethodsThis multicenter prospective cohort study included 145 patients recently diagnosed with IBD. Data on clinical and demographic characteristics, anxiety and depression scales, and IBD activity were collected in two telephone surveys, during and after the first COVID-19 lockdown in Spain. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated.ResultsDuring lockdown, 33.1% and 24.1% scored high on the anxiety and depression scales, respectively. Independent factors related to anxiety (all values ORs; 95% CIs) during lockdown were female sex (2; 1.2–5.4) and IBD activity (4.3; 1.8–10.4). Factors related to depression were comorbidity (3.3; 1.1–9.8), IBD activity (6; 1.9–18.1), use of biologics (2.9; 1.1–7.6), and living alone or with one person (3.1; 1.2–8.2). After lockdown, anxiety and depression symptoms showed significant improvement, with 24.8% and 15.2% having high scores for anxiety and depression, respectively. Factors related to post-lockdown anxiety were female sex (2.5; 1.01–6.3), Crohn's disease (3.3; 1.3–8.5), and active IBD (4.1; 1.2–13.7). Factors associated with depression were previous history of mood and/or anxiety disorders (6.3; 1.6–24.9), active IBD (7.5; 2.1–26.8), and steroid use (6.4; 1.4–29).ConclusionsLockdown during the COVID-19 pandemic had a significant psychological impact in patients with IBD. Disease activity was related to the presence of anxiety and depression symptoms during and after lockdown.
