Chronic stress induces hypersensitivity of murine gastric vagal afferents. Neurogastroenterol Motil 2019; 31:e13669. [PMID: 31241809 DOI: 10.1111/nmo.13669] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2019] [Revised: 05/22/2019] [Accepted: 06/18/2019] [Indexed: 12/11/2022]
Abstract
BACKGROUND Stress exposure is known to trigger and exacerbate functional dyspepsia (FD) symptoms. Increased gastric sensitivity to food-related stimuli is widely observed in FD patients and is associated with stress and psychological disorders. The mechanisms underlying the hypersensitivity are not clear. Gastric vagal afferents (GVAs) play an important role in sensing meal-related mechanical stimulation to modulate gastrointestinal function and food intake. This study aimed to determine whether GVAs display hypersensitivity after chronic stress, and whether its interaction with leptin was altered by stress. METHODS Eight-week-old male C57BL/6 mice were exposed to unpredictable chronic mild stress or no stress (control) for 8 weeks. The metabolic rate, gastric emptying rate, and anxiety- and depression-like behaviors were determined. GVA mechanosensitivity, and its modulation by leptin, was determined using an in vitro single fiber recording technique. QRT-PCR was used to establish the levels of leptin and leptin receptor mRNA in the stomach and nodose ganglion, respectively. KEY RESULTS The stressed mice had lower body weight and food intake, and increased anxiety-like behavior compared to the control mice. The mechanosensitivity of mucosal and tension-sensitive GVAs was higher in the stressed mice. Leptin potentiated mucosal GVA mechanosensitivity in control but not stressed mice. The expression of leptin mRNA in the gastric mucosa was lower in the stressed mice. CONCLUSIONS AND INFERENCES In conclusion, chronic stress enhances GVA mechanosensitivity, which may contribute to the gastric hypersensitivity in FD. In addition, the modulatory effect of leptin on GVA signaling is lost after chronic stress exposure.

Abstract
Gastrointestinal problems are common during wars, and they have exerted significant adverse effects on the health of service members involved in warfare. The spectrum of digestive diseases has varied during wars of different eras. At the end of the 20th century, new frontiers of military medical research emerged due to the occurrence of high-tech wars such as the Gulf War and the Kosovo War, in which ground combat was no longer the primary method of field operations. The risk to the military personnel who face trauma has been greatly reduced, but disease and non-battle injuries (DNBIs) such as neuropsychological disorders and digestive diseases seemed to be increased. Data revealed that gastrointestinal symptoms such as constipation, diarrhea, dyspepsia, and noncardiac chest pain are common among military personnel during modern wars. In addition, a large number of deployed soldiers and veterans who participated in recent wars presented with chronic gastrointestinal complaints, which fulfilled with the Rome III criteria for functional gastrointestinal disorders (FGIDs). It was also noted that many veterans who returned from the Gulf War suffered not only from chronic digestive symptoms but also from neuropsychological dysfunction; however, they also showed symptoms of other systems. Presently, this broad range of unexplained symptoms is known as "Gulf War syndrome". The mechanism that underlies Gulf War syndrome remains unclear, but many factors have been associated with this syndrome such as war trauma, stress, infections, immune dysfunction, radiological factors, anthrax vaccination and so on. Some have questioned if the diagnosis of FGIDs can be reached given the complexity of the military situation. As a result, further studies are needed to elucidate the pathogenesis of gastrointestinal disease among military personnel.

From ischochymia to gastroparesis: proposed mechanisms and preferred management of dyspepsia over the centuries. Dig Dis Sci 2014; 59:1088-98.

Abstract
Dyspeptic symptoms are common with most patients suffering functional disorders that remain a therapeutic challenge for medical practitioners. Within the last three decades, gastric infection, altered motility, and hypersensitivity have gained and lost traction in explaining the development of functional dyspepsia. Considering these shifts, the aim of this review was to analyze changing understanding of and approaches to dyspepsia over a longer time period. Monographs, textbooks, and articles published during the last three centuries show that our understanding of normal gastric function has improved dramatically. With increased insight came new ideas about disease mechanisms, diagnostic options, and treatments. Despite shifts over time, the importance of functional abnormalities was recognized early on and explained in the context of societal influences and stressors, anxieties, and biological influences, thus resembling the contemporary biopsychosocial model of illness. Symptoms were often attributed to changes in secretion, motility, and sensation or perception with technological innovation often influencing proposed mechanisms and treatments. Many of the principles or even agents applied more than a century ago are still part of today's approach. This includes acid suppression, antiemetics, analgesics, and even non-pharmacologic therapies, such as gastric decompression or electrical stimulation of the stomach. This historical information does not only help us understand how we arrived at our current state of knowledge and standards of care, it also demonstrates that enthusiastic adoption of various competing explanatory models and the resulting treatments often did not survive the test of time. In view of the benign prognosis of dyspepsia, the data may function as a call for caution to avoid the potential harm of overly aggressive approaches or treatments with a high likelihood of adverse effects.

Abstract
INTRODUCTION Function dyspepsia (FD) may cause patients to suffer from anxiety and depression, and psychosocial disorders would have a significant effect on FD symptoms. AIM To examine the prevalence of anxiety and depression among function dyspepsia (FD) patients and to identify social factors of anxiety-depression among FD patients. MATERIAL AND METHODS Patients with FD, who fulfilled the Rome III criteria, were enrolled. All patients were administered a validated Chinese version of the self-rating scale (SDS) and self-rating anxiety scale (SAS), and investigated regarding the patients' social factors. RESULTS A total of 907 patients were enrolled, including 516 (56.89%) FD patients within anxiety-depression status; SDS mean scores were 51.57 ±8.22; SAS mean scores were 51.04 ±7.53; 52.28% were male and 64.25% were female (χ(2) = 262.54, p < 0.01); 56.16% were aged 18-29 years, 54.15% were aged 30-39 years, 54.77% were aged 40-49 years, 62.02% were aged 50-59 years, 69.23% were aged above 60 years (χ(2) = 18.14, p < 0.01); 67.44% were the retirees; 63.31% were manual workers; 55.10% were soldiers; 43.57% were mental workers; 38.89% were students (χ(2) = 716.53, p < 0.01); 64.20% had junior high school degree or below; 57.36% had high school degrees; 42.03% had college degrees; 44.44% had master's or above degrees (χ(2) = 27.21, p < 0.05); 38.10% were in good health condition; 61.90% were in poor health condition (χ(2) = 7.94, p < 0.01); 20.31% had correlative family history; and 79.69% had no correlative family history (χ(2) = 2.23, p > 0.05). CONCLUSIONS The FD patients have higher rates of anxiety and depression. Gender, age, occupation, education level, and health condition have a significant effect on anxiety and depression status. Female gender, advanced age, high-stress occupation, lower education level, and poor health condition all are risk factors. Family history has no relationship with anxiety and depression among FD patients.

Abstract
In this Review, after a brief historical introduction, we first provide an overview of epidemiological studies that demonstrate an association between functional dyspepsia and psychological traits, states or psychiatric disorders. These studies suggest an important intrinsic role for psychosocial factors and psychiatric disorders, especially anxiety and depression, in the aetiopathogenesis of functional dyspepsia, in addition to their putative influence on health-care-seeking behaviour. Second, we describe pathophysiological evidence on how psychosocial factors and psychiatric disorders might exert their role in functional dyspepsia. Novel insights from functional brain imaging studies regarding the integration of gut-brain signals, processed in homeostatic-interoceptive brain regions, with input from the exteroceptive system, the reward system and affective and cognitive circuits, help to clarify the important role of psychological processes and psychiatric morbidity. We therefore propose an integrated model of functional dyspepsia as a disorder of gut-brain signalling, supporting a biopsychosocial approach to the diagnosis and management of this disorder.

Abstract
BACKGROUND AND AIM The prevalence of functional gastrointestinal disorders (FGID) in adolescents and their relationship to quality of school life (QOSL) are not fully understood. This study investigated the relationship between FGID and QOSL. METHODS Adolescents (10-17 years) were recruited from 40 schools. FGID diagnoses were based on the Questionnaire on Pediatric Gastrointestinal Symptoms-Rome III version (QPGS-RIII). QOSL was evaluated by a questionnaire and calculated as the QOSL score. RESULTS Five hundred and fifty-two of the 3976 students (13.9%) met the FGID criteria for one or more diagnoses according to the QPGS-RIII: 12.3% met the criteria for one, 1.5% for two or more. Irritable bowel syndrome (IBS) was the most common diagnosis (5.9%) followed by functional abdominal pain (3.1%). The prevalence of FGID was significantly higher in the female students in comparison to male students (P < 0.01). The prevalence of FGID was 9.5% in elementary school, 15.4% in junior high school, 26.0% in high school students, respectively. The prevalence of FGID was significantly increased with age (P < 0.01). The QOSL score of the patients with FGID was 10.9 ± 4.5 and that without FGID was 8.2 ± 2.8, respectively. The QOSL score of the patients with FGID was significantly worse than those without FGID (P < 0.01). The QOSL scores with IBS, aerophagia, and cyclic vomiting syndrome were significantly worse among the FGID (P < 0.01). CONCLUSIONS The prevalence of FGID in adolescents was relatively high. The presences of FGID worsen the QOSL score. Medical intervention and/or counseling are needed for such students to improve the QOSL.

Abstract
OBJECTIVES Lowered visceral sensory thresholds are a key finding in at least a subgroup of patients with functional bowel disorders. Stress and inflammation contribute to this altered visceral sensory function. We aimed to elucidate the role of repetitive stress and acute mucosal inflammation, alone and in combination, on sensory function. METHODS In randomized order, trinitrobenzenesulfonic acid (TNBS) plus the equal amount of ethanol or saline were instilled into the colorectum of female Lewis rats. Colorectal distensions (CRD) were performed with a barostat device (3 min/40 mmHg); to quantify the visceromotor response (VMR) to CRD, electromyographic activity (EMG) of the abdominal muscles was recorded. In randomized order, equal numbers of both treatment groups underwent either seven days (1 h/day) repetitive water avoidance stress (WAS) or sham WAS. CRD's were conducted 28 days later. Colonic tissue samples were obtained to characterize inflammation and blood samples were taken at day 28 to measure plasma IL-2 levels by enzyme-linked immunosorbent assay (ELISA). RESULTS Compared to controls (662+/-114 microV) TNBS (1081+/-227 microV), WAS (1366+/-125 microV) and the combination of both (1477+/-390 microV) significantly augmented the VMR to CRD. TNBS and/or WAS caused significant inflammatory changes at day 5, while only TNBS+WAS also showed signs of mucosal inflammation on day 14 and significantly elevated IL-2 levels on day 28. CONCLUSIONS Stress and inflammation cause long lasting alterations of visceral sensory function. Concomitant stress further increases post-inflammatory visceral hyperalgesia.

Abstract
OBJECTIVES The aim of the study is to identify factors that are associated with dyspeptic symptoms in patients with functional dyspepsia (FD) in a multivariate context. METHODS Demographic data, personal habits, stressful life events, and psychological distress were compared between functional dyspeptic patients with gastric reddish streaks and asymptomatic counterparts who underwent upper gastrointestinal endoscopy as part of a self-paid physical check-up. RESULTS There were 93 patients in the symptomatic group and 67 patients in the asymptomatic group. FD patients had a lower proportion of tea consumption (38 vs. 61%, P = 0.004), more were single (20 vs. 6%, P<0.05), less belief in religion (46 vs. 66%, P<0.05), a greater number (median+/-interquartile range, 3.0+/-2.0 vs. 2.0+/-2.0, P<0.001) and more severity (1.5+/-0.9 vs. 1.0+/-1.0, P<0.001) with regard to stressful life events, greater scores of symptom dimensions of somatization, depression, anxiety, and psychotism and general severity index of psychopathology as compared with asymptomatic counterparts. Only tea consumption [odds ratio (OR) = 0.33, 95% confidence interval (CI) = 0.15-0.72, P<0.01)], religion (OR = 0.42, 95% CI = 0.19-0.91, P<0.05), number of stressful life events (OR = 2.74, 95% CI = 1.28-5.88, P<0.01), and somatization (OR = 6.80, 95% CI = 1.21-38.08, P<0.05) remained statistically significant in multivariate analysis. CONCLUSION FD with gastric reddish streaks exhibited increased somatization, more stressful life events, less belief in religion, and less tea consumption as compared with asymptomatic counterparts. The findings of the study suggest the importance of adopting a more comprehensive holistic bio-psycho-socio-spiritual model when dealing with FD patients.

Abstract
OBJECTIVE To determine whether gastric emptying, stomach peristaltic frequencies, stress profile, depressive symptoms, anxiety, and salivary cortisol levels could predict functional dyspepsia (FD). METHODS Magnetogastrography (MGG) was used to measure gastric emptying time and the gastric peristaltic frequencies in 15 patients with FD diagnosis and in 17 healthy volunteers. In all the participants, stress profile, anxiety, and depressive symptoms were evaluated by means of standardized questionnaires, and morning salivary samples were collected for the measurement of cortisol levels. A univariate logistic regression model was used to examine the probability of the measured variables to predict the presence of FD. RESULTS The univariate logistic regression model showed that the half-time of gastric emptying (OR=1.16 P=.01); the subscale of stress items (OR=1.08, P=.003); negative appraisal of subscale coping strategies (OR=1.03, P=0.007); anxiety (OR=1.05, P=.01); and depression (OR=1.23, P=.02) had a significant predictive value for the presence of FD. However, by applying the stricter multiple comparison criteria, only stress, negative appraisal, and anxiety arose as predictors of FD. The FD patients compared with healthy volunteers showed significantly elevated half-time of gastric emptying (P<.0006), high scores in the subscales of stress (P<.000003), in behavior type "A" (P<.04), in coping styles (P<.008), in depression (P<.0004), and in anxiety (P<.0002). CONCLUSIONS These findings indicate that psychosocial stress, mood symptoms, and coping style are predictors of FD. The stress shows high sensibility and specificity in the patients with FD, indicating a contribution in the etiopathogenesis of dyspepsia.

Abstract
BACKGROUND The pathophysiology of upper gastrointestinal (GI) symptoms is still poorly understood. Psychological symptoms were found to be more common in patients with functional gastrointestinal complaints, but it is debated whether they are primarily linked to GI symptoms or rather represent motivations for health-care seeking. Purpose of our study was to compare co-morbidity, in particular psychological and social problems, between patients with and without upper GI symptoms. In addition, we investigated whether the prevalence of psychological and social problems is part of a broader pattern of illness related health care use. METHODS Population based case control study based on the second Dutch National Survey of general practice (conducted in 2001). Cases (adults visiting their primary care physician (PCP) with upper GI symptoms) and controls (individuals not having any of these complaints), matched for gender, age, PCP-practice and ethnicity were compared. Main outcome measures were contact frequency, prevalence of somatic as well as psychosocial diagnoses, prescription rate of (psycho)pharmacological agents, and referral rates. Data were analyzed using odds ratios, the Chi square test as well as multivariable logistic regression analysis. RESULTS Data from 13,389 patients with upper GI symptoms and 13,389 control patients were analyzed. Patients with upper GI symptoms visited their PCP twice as frequently as controls (8.6 vs 4.4 times/year). Patients with upper GI symptoms presented not only more psychological and social problems, but also more other health problems to their PCP (odds ratios (ORs) ranging from 1.37 to 3.45). Patients with upper GI symptoms more frequently used drugs of any ATC-class (ORs ranging from 1.39 to 2.90), including psychotropic agents. The observed differences were less pronounced when we adjusted for non-attending control patients. In multivariate regression analysis, contact frequency and not psychological or social co-morbidity was strongest associated with patients suffering from upper GI symptoms. CONCLUSION Patients with upper GI symptoms visit their PCP more frequently for problems of any organ system, including psychosocial problems. The relationship between upper GI symptoms and psychological problems is equivocal and may reflect increased health care demands in general.

BACKGROUND Personality and psychiatric disorders are reported to be more common in dyspeptic patients with severe complaints, but it remains unclear whether this association exists for patients with mild and moderate dyspepsia. AIM To study the association between dyspeptic symptom severity and psychopathology, major life events and coping ability in patients with a new episode of dyspepsia. METHODS; Dyspeptic symptom severity was measured using the validated eight symptom Veldhuyzen van Zanten questionnaire. Psychopathology was measured using the Symptom Check List-90 (SCL 90). Major life events were measured with a modified version of the Social Readjustment Rating Scale (SRRS). Coping styles were measured by a short version of the Utrecht Coping Questionnaire, distinguishing six coping styles. Linear regression was used to assess the relationship between dyspepsia symptom severity and psychological factors. RESULTS In all, 664 patients with a new episode of uninvestigated dyspepsia, aged >18 years were included. Dyspeptic symptom severity was positively correlated with the presence of depression (P < 0.01), somatization symptoms (P < 0.01), use of an active coping style (P < 0.01) and negatively correlated with age (P < 0.01). CONCLUSIONS Primary care patients consulting with dyspepsia have higher levels of depression and somatization especially at younger age. An active coping style is associated with dyspepsia symptom severity.

Abstract
Primary care physicians and clinics have become the frontline of health care for most Americans-they are the first point of contact and the source of both treatment and referrals. Psychosocial problems, such as difficulty with finances, family, housing, and work, are associated with a high demand for medical care in primary care practice, yet little is known about the prevalence of psychosocial problems in primary care settings. The purpose of this study is to assess the type and level of psychosocial problems in primary care patients by examining patient and provider perceptions at the Veterans Affairs Greater Los Angeles Healthcare System (VAGLAHS). A purposive sample of 684 veterans and a convenience sample of 59 providers anonymously completed the Social Needs Checklist. Patients reported an average of five psychosocial problems, with finances, personal stress, transportation, employment, and legal issues being the most prevalent. Thirty-two percent of patients indicated a desire to see a social worker. Provider and patient differences were compared. Provider estimates of patients' problems were consistently lower than patient estimates in all psychosocial problem areas except need for nursing home placement and problem drinking or drug use. Implications for social work in primary care are discussed.

Abstract
The role of the brain-gut axis interaction in the pathogenesis of irritable bowel syndrome (IBS) is not well understood. To examine this possibility, a novel rat model of IBS subjected to both chronic and acute stress (CAS) was established. G proteins play a crucial role in the pathophysiology of depression. The alpha 2A adrenoceptor (alpha(2A)-AR) and the norepinephrine reuptake transporter (NET) determine the sympathetic signal activity. It is conceivable that stress may induce brain G proteins, colonic alpha(2A)-ARs, and NET abnormal expression, which may be responsible for the abnormalities in IBS. Colonic motility, visceral sensation, and secretion were assessed by counting fecal pellets, abdominal muscle contractions in response to colorectal balloon distension (CRD), and short-circuit current study, respectively. Western blot analysis was used to investigate the expression of G proteins, alpha(2A)-ARs, and NET. Compared with control animals, the colonic epithelial secretion, fecal pellets, and numbers of abdominal muscle contraction induced by CRD were significantly higher in both acute stress only (AS) and CAS rats. However, the G proteins, alpha(2A)-AR, and NET expression changed differently in AS and CAS rats. We showed that exposure to either AS or CAS would cause the increase of secretion, motility, and sensation, but the change of protein expression in brain-gut axis was different. It may be responsible for the pathogenesis of IBS.

Abstract
Functional gastrointestinal disorders (FGIDs) affect millions of people without regard for age, race or sex, but little information related to FGIDs and few methods are available for diagnosing FGIDs. Therefore, the aims of this study were to investigate any alterations to the gastrointestinal tracts induced by FGIDs and to develop and test an ultrasonic diagnostic system capable of detecting the alteration in the gastrointestinal tract. Palpation/percussion examinations were performed on 40 participants with or without FGIDs to identify any mechanical alterations to the gastrointestinal tract induced by FGIDs. An ultrasonic diagnostic system for FGIDs was developed and clinical trials were performed on same participants used in the palpation/percussion examinations to test the system under actual clinical conditions. The results obtained from the palpation/percussion examinations showed that a gastrointestinal tract with a FGID became more rigid than a healthy tract (p < 0.05). Clinical trials also showed that gastrointestinal tracts in the patient group with FGIDs were in fact more rigid than those in the control group without FGIDs (p < 0.05). These findings indicated that our newly designed ultrasonic diagnostic system may be useful in clinics to accurately diagnose FGIDs through detecting mechanical alterations to the rigidity of the gastrointestinal tract induced by FGIDs. The current study may be valuable by identifying for the first time mechanical alterations of the gastrointestinal tract induced by FGIDs and may prove valuable as the first step in the development of a diagnostic system for FGIDs.

Abstract
OBJECTIVE According to the psychiatric hypothesis, the symptoms of dyspepsia may be due to depression, anxiety or a somatization disorder. We investigated the frequency of psychiatric symptoms in patients undergoing endoscopic procedures with dyspepsia, either with or without pathological findings, and compared this with control subjects without dyspeptic symptoms. METHODS Ninety patients with dyspeptic symptoms and 90 control subjects participated in the study. Both the patients and the controls were asked to complete a questionnaire about socio-demographic characteristics, the Turkish version of the Spielberger State-Trait Anxiety Inventory (STAI) and the Symptom Check List-90 (SCL-90). In order for us to determine whether the criteria for any of the conditions listed in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) were met, the patients were asked to take part in the Structured Clinical Interview for DSM-IV disorders. RESULTS Of the participants, 47.8% had a psychiatric disorder according to DSM-IV criteria, somatoform disorder (44.2%) being the most common. While 42.2% patients were determined to have a pathological finding using endoscopic evaluation, 57.8% had no findings. Together with the somatization and obsessive-compulsive disorder subscale scores, the total SCL-90 score and the mean trait anxiety score were statistically significantly higher in participants with no pathological findings. There were trends for anxiety (13.2% vs. 7.7%) and mood (2.6% vs. 0.0%) disorders to be more frequent in patients with pathological findings, while somatoform disorder+depressive disorder (17.3% vs. 5.2%) was more frequent in patients with no findings, although the differences were not statistically significant (Z=0.7, P>.05). The scores of state-trait anxiety, somatization, obsession-compulsion, depression, anxiety, phobic anxiety and psychotism subscales, and the total SCL-90 score were statistically significantly higher in those participants without a pathological finding than in the controls. CONCLUSIONS Regarding the high frequency of psychiatric disorders in patients with dyspeptic symptoms, we think that such patients should be evaluated by two separate departments, gastroenterology and psychiatry.

Abstract
BACKGROUND A psychosocial conceptualization for irritable bowel syndrome and unexplained dyspepsia has been proposed, but remains untested. We conducted a comprehensive population-based study to determine what psychiatric and psychosocial factors, if any, are important in irritable bowel syndrome and dyspepsia. METHODS Two hundred and seven participants identified from two previous Australian population surveys who also met Rome I criteria for irritable bowel syndrome (n=156) or unexplained dyspepsia (n=51) were included in the study. Consulters (n=103) were those who had had visited their general practitioner for gastrointestinal symptoms at least once in the prior 12 months. Nonconsulters had not sought medical care for gastrointestinal symptoms in the past year. Controls (n=100) did not report having any abdominal pain in a previous population survey. Psychosocial variables were assessed using structured interviews and validated self-report measures. RESULTS Psychiatric diagnoses, neuroticism, more highly threatening life event stress, an external locus of control and ineffectual coping styles were significantly associated with having a diagnosis of irritable bowel syndrome and/or dyspepsia. Only somatization (odds ratio=5.28, 95% confidence interval 1.57-17.68), however, was independently associated with irritable bowel syndrome. Psychosocial factors did not discriminate between consulters and nonconsulters. CONCLUSIONS Somatization is likely play a key role in explaining irritable bowel syndrome but not dyspepsia.

Abstract
The pathogenesis of Functional Dyspepsia (FD) remains unclear, appears diverse and is thus inadequately understood. Akin to other functional gastrointestinal disorders, research has demonstrated an association between this common diagnosis and psychosocial factors and psychiatric morbidity. Conceptualising the relevance of these factors within the syndrome of FD requires application of the biopsychosocial model of disease. Using this paradigm, dysregulation of the reciprocal communication between the brain and the gut is central to symptom generation, interpretation and exacerbation. Appreciation and understanding of the neurobiological correlates of various psychological states is also relevant. The view that psychosocial factors exert their influence in FD predominantly through motivation of health care seeking also persists. This appears too one-dimensional an assertion in light of the evidence available supporting a more intrinsic aetiological link. Evolving understanding of pathogenic mechanisms and the heterogeneous nature of the syndrome will facilitate effective management. Co-morbid psychiatric illness warrants treatment with conventional therapies. Acknowledging the relevance of psychosocial variables in FD, the degree of which is subject to variation, has implications for assessment and management. Available evidence suggests psychological therapies may benefit FD patients particularly those with chronic symptoms. The rationale for use of psychotropic medications in FD is apparent but the evidence base to support the use of antidepressant pharmacotherapy is to date limited.

Abstract
Symptoms of functional dyspepsia are characterized by upper abdominal discomfort or pain, early satiety, postprandial fullness, bloating, nausea and vomiting. It is a chronic disorder, with symptoms more than 3 mo per year, and no evidence of organic diseases. Dysfunctional motility, altered visceral sensation, and psychosocial factors have all been identified as major pathophysiological mechanisms. It is believed that these pathophysiological mechanisms interact to produce the observed symptoms. Dyspepsia has been categorized into three subgroups based on dominant symptoms. Dysmotility-like dyspepsia describes a subgroup of patients whose symptom complex is usually related to a gastric sensorimotor dysfunction. The brain-gut peptide cholecystokinin (CCK) and serotonin (5-HT) share certain physiological effects. Both have been shown to decrease gastric emptying and affect satiety. Furthermore the CCK induced anorexia depended on serotonergic functions probably acting via central pathways. We believe that abnormalities of central serotonergic receptors functioning together with a hyper responsiveness to CCK or their interactions may be responsible for the genesis of symptoms in functional dyspepsia (FD).

Abstract
There are a number of abnormalities of gastrointestinal function, including sensory and motor dysfunction, which are believed to play a role in the manifestation of symptoms in patients with functional gastrointestinal disorders (FGID). In addition, there is a remarkable psychiatric comorbidity. Family and twin studies have provided strong evidence for a clustering of FGID in families and an increased concordance in monozygotic compared to dizygotic twins. This points towards the role of one or more hereditary (genetic) factors. Considering these disorders of function and the psychiatric comorbidity, polymorphisms of adrenergic, opioidergic or serotonergic receptors as well as G-protein beta3 (GNB3) subunit gene polymorphisms (C825T) and polymorphisms of 5-HT transporter genes are suitable causes. In addition, mediators or regulators of mucosal inflammation may trigger events that ultimately result in the manifestation of FGID. Thus, relevant polymorphisms of genes with immunmodulating and/or neuromodulating features (OPRM1, IL-4, IL-4R, TNFalpha) may also play a role in the manifestation of FGIDs.

Abstract
OBJECTIVE Psychosocial stressors have been associated with exacerbations of symptoms in functional and inflammatory disorders of the gastrointestinal tract. The present longitudinal study tests the general hypothesis that life stressors can exacerbate symptoms in patients with chronic heartburn. METHODS Sixty subjects with current heartburn symptoms were recruited by community advertisement and assessed for presence of stressful life events retrospectively over the preceding 6 months and prospectively for 4 months. Symptom severity by daily diary, quality of life, and psychological symptoms of anxiety, depression, and vital exhaustion were also measured. RESULTS The presence of a severe, sustained life stress during the previous 6 months significantly predicted increased heartburn symptoms during the following 4 months. In addition, symptoms showed a strong, independent correlation with vital exhaustion. Affective and subjective stress ratings were not strongly related to heartburn severity; however, anxiety showed the strongest relationship to impaired quality of life and depression to heartburn medication use. CONCLUSIONS As with other chronic conditions such as irritable bowel syndrome (IBS), heartburn severity appears to be most responsive to major life events and not an accumulation of more minor stressors or fluctuations in mood. In addition, vital exhaustion, which may in part result from sustained stress, may represent the psychophysiological symptom complex most closely associated with heartburn exacerbation. Potential mechanisms for these results include increased level and frequency of esophageal acid exposure, inhibition of gastric emptying of acid, or stress-induced hypersensitivity.

Abstract
Functional dyspepsia is a common condition, but as yet, the underlying etiology is unclear. In this article, upper gastrointestinal motor and sensory physiology are reviewed and the current evidence for motor and/or sensory functional abnormalities causing dyspeptic symptoms is presented. The complex interrelationship between abnormal motor activity and sensation is explored, as well as the potential roles for autonomic dysfunction and psychological state in modulating gastrointestinal sensation and motor function. Finally, based on clinical trial evidence, a treatment pathway for functional dyspepsia is suggested.

Abstract
BACKGROUND & AIMS Levosulpiride is a benzamide derivate D(2) dopamine antagonist with prokinetic activity that can accelerate gastric emptying and reduce discomfort in response to gastric distention. The aim of the study is to compare the clinical efficacy of levosulpiride and cisapride in patients with dysmotility-like functional dyspepsia. METHODS In a exploratory pilot study performed as a multicenter, randomized, double-masked trial, the effects of 8 weeks of treatment with either levosulpiride, 25 mg, 3 times daily (n = 69) or cisapride, 10 mg, 3 times daily (n = 71) were compared. Individual symptoms (pain/discomfort, fullness, bloating, early satiety, and nausea/vomiting), global symptom score, effect on health-related quality of life (HRQoL), and anxiety-state and anxiety-trait were evaluated. Adverse events also were recorded. RESULTS Both levosulpiride and cisapride improved dyspeptic symptoms and decreased total symptom score (79.9% and 71.3%, respectively); no significant statistical difference between treatments was found (P = 0.07 for total symptom score). HRQoL improved similarly after both treatments, whereas no change was observed in anxiety. Medication-related adverse effects were present in 13 of 69 patients (18.8%) in the levosulpiride group and 8 of 71 patients (11.3%) in the cisapride group. Significantly more (P = 0.03) patients treated with cisapride had to abandon the trial because of side effects. CONCLUSIONS Levosulpiride is at least as effective as cisapride in the treatment of dysmotility-like functional dyspepsia.

Abstract
BACKGROUND It is widely accepted based on volunteer studies that levels of psychological distress are similar in those with functional gastrointestinal (GI) disorders and health in the community, while increased psychological distress in outpatients is largely explained by health-care seeking. AIMS To determine if psychological distress, life event stress, or social support is associated with functional GI disorders in a population-based study. METHODS A nested case-control study was performed by first mailing a self-report bowel disease questionnaire to a random sample of Olmsted County, Minnesota, aged 20-50 yr. All persons who reported symptoms of nonulcer dyspepsia (NUD) or irritable bowel syndrome (IBS) (cases), or an absence of GI symptoms (controls), were invited to complete a series of validated questionnaires designed to measure psychological distress, life event stress, social support, current symptoms, and physician visits. RESULTS 103 subjects with functional GI disorders and 119 controls participated (85% of eligible). Functional GI disorders were more likely to be reported by those with higher scores on each of the nine SCL-90-R scales used to measure psychological distress (except phobic anxiety), and those with more negative and total life event stress. In a multiple logistic regression model (including age and gender), somatization, interpersonal sensitivity, and total life event stress were independently associated with functional GI disorders. Findings were similar when subjects with the IBS and NUD were analyzed separately compared to controls. CONCLUSIONS Contrary to current dogma, psychosocial factors were significantly associated with functional GI disorders in this community sample. This suggests that these factors may be involved in the etiopathogenesis rather than just driving health-care utilization.

Abstract
BACKGROUND The health-related quality of life is impaired in patients with functional gastrointestinal disorders seen in referral centres. AIM To determine whether the health-related quality of life is impaired in subjects with functional disorders in the community and whether any differences can be explained by psychological co-morbidity. METHODS In a population-based, nested, case-control study, subjects reporting symptoms of either dyspepsia or irritable bowel syndrome and healthy controls were interviewed and completed a battery of psychological measures plus a validated, generic, health-related quality of life measure (Medical Outcomes Study 36-item short form health survey, SF-36). The association between irritable bowel syndrome and dyspepsia and the physical and mental composite scores of SF-36 were assessed with and without adjustment for psychological state. RESULTS One hundred and twelve cases (30 dyspepsia, 39 irritable bowel syndrome, 32 dyspepsia and irritable bowel syndrome and 11 gastrointestinal symptoms but not dyspepsia or irritable bowel syndrome) and 110 controls were enrolled. In the unadjusted linear regression models, irritable bowel syndrome (but not dyspepsia) was negatively associated with the physical composite score (P < 0.05); in an adjusted model, the association between the physical health-related quality of life and irritable bowel syndrome was explained by the Symptom Checklist-90 somatization score alone. In unadjusted models, irritable bowel syndrome and dyspepsia were each negatively associated with the mental composite score (P < 0.05). The association between the mental health-related quality of life and dyspepsia remained after adjusting for psychological covariates, but the association between this and irritable bowel syndrome was not significant after adjustment. CONCLUSIONS In the community, health-related quality of life is impaired in subjects with irritable bowel syndrome and dyspepsia; however, much of this association can be explained by psychological factors.

Abstract
Patients with irritable bowel syndrome (IBS) are characterized by a broad spectrum of gastrointestinal (GI) symptoms. These IBS-symptoms and symptoms of other functional GI disorders frequently overlap. Moreover, at least in patients with severe disease manifestations there is a remarkable psychiatric comorbidity. There is a number of abnormalities of GI functions including sensory and motor dysfunction that are believed to play a role for the manifestation of symptoms in patients with these functional gastrointestinal disorders (FGID). Family studies provide strong evidence for a clustering of FGID in families. Furthermore, twin studies clearly demonstrate an increased concordance in monocygotic compared to dicygotic twins. This points towards the role of one or more hereditary factors. Considering sensory and motor function as well as the psychiatric comorbidity, polymorphisms of adrenergic, opioidergic or serotonergic receptors as well as G-protein beta3 (GNB3) subunit gene polymorphism and polymorphisms of 5-HT transporter genes are suitable mechanisms for these abnormalities. Hence acute GI infections with a mucosal inflammation appear to trigger a cascade of events that ultimately results in the manifestation of FGID, it is reasonable to assume that functionally relevant polymorphisms of genes with immunmodulating and/or neuromodulating features (OPRM1, IL-4, IL-4R, TNFalpha) play a role. It has emerged that a number of various factors may contribute to the manifestation of functional GI disorders. The currently symptom based labels for functional GI disorders may be helpful to categorize patients and target therapy. However, various underlying pathophysiologies may cause similar symptom patterns. Thus, it is reasonable to anticipate that IBS will be dissected accordingly and our disease concepts will accept the irritable bowel syndrome as the clinical manifestation of a number of different disorders.

Abstract
BACKGROUND The importance of intestinal dysmotility in functional dyspepsia is a controversial issue. GOALS To investigate the orocecal transit time in patients with functional dyspepsia, as well as a possible association between intestinal transit and the presence of anxiety or Helicobacter pylori infection in these patients. STUDY The participants in this study were 23 patients with dysmotility-like functional dyspepsia and 24 control subjects. Orocecal transit time was measured by the lactulose hydrogen breath test. The presence of anxiety was assessed by the Hospital Anxiety and Depression (HAD) scale. RESULTS No significant difference in orocecal transit times was found between patients (median, 55 minutes; 95% confidence interval [CI], 40-60 minutes) and control subjects (median, 50 minutes; 95% CI, 40-60 minutes; p = 1). In the assessment, 15 patients (73%) scored for anxiety on the HAD scale, and 15 patients (65%) had positive test results for H. pylori. There was no significant difference in orocecal transit times between the patients with (median, 55 minutes; 95% CI, 40-63 minutes) and those without H. pylori infection (50 minutes; 95% CI, 40-68 minutes; p = 0.85), or between the patients with (median, 45 minutes; 95% CI, 40-68 minutes) and those without (60 minutes; 95% CI, 40-63 minutes; p = 0.77) anxiety. CONCLUSIONS Orocecal transit time is within the normal range in patients with functional dyspepsia. Anxiety and H. pylori infection do not seem to influence orocecal transit time in these patients.

Abstract
Over the past decade, while gastroenterologists' interest in mind-body interactions in organic disorders dwindled, stronger evidence has linked psychosocial factors with the incidence and recurrence of peptic ulcer and with the course of inflammatory bowel disease. Psychological-behavioral approaches to treatment continue to be disappointing. Psychosocial factors may affect ulcer by increasing duodenal acid load, altering local circulation or motility, intensifying Helicobacter pylori infection, stimulating corticosteroid secretion, and affecting health risk behaviors; possible mechanisms for inflammatory bowel disease include immune deregulation, gut permeability changes, and poor medication adherence. Both belong to the growing category of diseases thought to have an infectious component: for peptic ulcer the bacterium Helicobacter pylori, for inflammatory bowel disease an exaggerated immune response to gut bacteria. Peptic ulcer and inflammatory bowel disease, which present unique interactions among psychological, immunologic, endocrine, infectious, and behavioral factors, are splendid paradigms of the biopsychosocial model.

Abstract
OBJECTIVE Subjects with functional dyspepsia (FD) in most previous studies have been confined to those who sought medical consultation. The generalizability of results from these studies to individuals with FD who do not seek medical consultation is limited. This study examined 1) differences in perceptual and behavioral characteristics between "nonconsulters" and "consulters" with FD and 2) the influence of these characteristics on dyspeptic and psychological symptoms. METHODS A matched case-control design was used to compare differences among 43 nonconsulters with FD, 43 consulters with FD, and 43 healthy individuals. Subjects' monitoring perceptual style, confrontative coping behaviors, dyspeptic symptoms, anxiety, and depression were assessed by using well-validated questionnaires. RESULTS FD consulters exhibited higher levels of monitoring, confrontative coping, anxiety, and depression than FD nonconsulters and healthy subjects (p values < .01). Results from discriminant analysis revealed that all these variables reliably predicted the membership of the three groups. Significant Monitoring by Confrontative Coping interaction effects were also found, indicating the conjoint influences of these variables on dyspeptic and psychological symptoms. CONCLUSIONS These results show that FD nonconsulters are distinguishable from FD consulters by their perceptual style, coping behaviors, and psychological symptoms. Both monitoring perceptual style and confrontative coping behaviors may magnify dyspeptic and psychological symptoms in individuals with FD, especially those who seek medical consultation.

Abstract
Thirty adults with upper gastrointestinal symptoms in the absence of structural organic disease diagnosed with non-ulcer dyspepsia (NUD) were compared to 30 healthy adults who had visited the hepatobiliary clinic for medical evaluation of non-organic complaints without NUD. Medical investigation in both groups were negative. Before independent gastrointestinal physicians conducted diagnostic evaluations, all subjects were evaluated for anxiety and depressive symptoms, stressful life events, coping style, and social support. The measures included Symptom Checklist 90-Revised (SCL-90-R), Beck Depression Inventory (BDI), Spielberger State-Trait Anxiety Inventory (STAI), Ways of Coping Checklist, and Interpersonal Support Evaluation List, and a self-report questionnaire, which measured the quantity of perceived stressful life events. The NUD patients reported significantly more symptoms of depression, more perceived stressful life events, less problem-focused coping, and less social support than the control subjects. Depressive symptoms were negatively correlated with interpersonal support, whereas, problem-focused coping was positively correlated with interpersonal support in the NUD patients. The two groups did not differ significantly in terms of anxiety and emotion-focused coping. The implications of these findings for the diagnosis and treatment of NUD are discussed.

Abstract
Upper gastrointestinal symptoms are a common complaint among the general population but only a small proportion of sufferers seek medical advice. The aim of this study was to examine what kind of perceptions persons using self medication have about the causes of their gastrointestinal symptoms, whether they have made any health-related lifestyle changes, and whether visits to a physician are related to lifestyle changes. A pharmacy-based survey was done in 10 pharmacies in the Helsinki area in 1995. The questionnaire was completed by 292 customers. The response rate was 53%. Respondents in a population-based health interview survey (n = 10,410) were used as a comparison group for poor health-behavior (consumption of tobacco, alcohol, coffee). The most common perceived causes of gastrointestinal symptoms were poor diet, coffee, and stress. Ignorance about possible causes of symptoms was especially common among less educated respondents and among those persons who had never visited a physician due to their symptoms. Respondents were significantly more often smokers and they had attempted to reduce their coffee and alcohol consumption more often than the general population. Those who had visited a physician during past year, less often had poor health-behavior and they had better knowledge about the possible causes of their symptoms. They had also made lifestyle changes more often, but after adjustment for background characteristics, physician visits were positively correlated only with coffee reduction. Counseling about healthy lifestyles, especially about smoking, should be increased in physician consultations and in pharmacies for all patients and customers having gastrointestinal problems.

Abstract
OBJECTIVE This study examines factors affecting the frequency of physician consultations by individuals with functional gastrointestinal disorders (FGD) in a group of subjects with functional dyspepsia or irritable bowel syndrome. Systematic selection of persons who were already seeing a physician for one of these problems was avoided by conducting an epidemiological field study rather than a clinical study. METHODS A representative sample of the German population (N=2201) completed a questionnaire that included, in addition to the criterion (number of physician visits in the past 12 months), items aimed at identifying the target group and questions about physical symptoms, illness behavior, living situation, personality features, and sociodemographic status (a total of 31 predictors). RESULTS Individuals with functional gastrointestinal disorders who consulted a physician for their gastrointestinal disorders and those who did not differed significantly, especially on psychological measures. The differences between these individuals and the general population were greater for the consulters than for the nonconsulters. Multiple regression analyses yielded nine predictors that explained 40.2% of the variance of the criterion. The best predictors of frequency of physician consultations were the duration of periods with symptoms and psychological factors, such as the severity of depression and the patients' views on the cause of their illness. CONCLUSIONS The psychopathology seen in people with functional gastrointestinal disorders is of two types: one is a characteristic of the illness itself and the other leads the individual to consult a physician. When gastroenterologists see patients with such disorders, they can assume that they may be dealing with a self-selected group of individuals with psychological stress. Psychological assessment would, therefore, be useful to determine whether a given individual with FGD might benefit from psychotherapy.

Abstract
OBJECTIVE Therapeutic trials in functional dyspepsia consistently show a substantial placebo response, but there is no clear explanation for such an effect. Our aim was to evaluate symptomatic, gastrointestinal motor, and gastric sensorial responses to placebo treatment in patients with chronic and severe functional dyspepsia who were part of a therapeutic trial. METHODS Thirty patients were treated during 8 wk with placebo (white-colored 8-mm tablets containing cellulose) by mouth, 20 min before breakfast, lunch, and dinner. We quantified the symptomatic response to placebo as a change in global health status, and also as a change in the individual and combined (global symptom index) of a five-symptom complex: upper abdominal pain, nausea, vomiting, bloating/fullness, and early satiety. Gastroduodenal motility, during fasting and postprandially, was evaluated by manometry in all patients pretreatment and in 17 patients posttreatment. Gastric sensitivity to distension was evaluated in 18 patients pretreatment and in five patients posttreatment (all of them clinical responders). RESULTS Placebo treatment produced a striking symptomatic improvement; by 8 wk 80% of the patients reported an improved global health status and their global symptom index markedly decreased (23.9+/-1.3 pretreatment vs 9.1+/-1.2; p < 0.05). Placebo increased the number of gastric phases III starting in the antrum during the fasting period (1.1+/-0.1 vs 1.6+/-0.2; p < 0.05). As a group, no significant changes in postprandial gastroduodenal motility were observed after placebo treatment. However, after placebo a significant improvement in the antral motility index (MI) was observed in the subset of patients with antral hypomotility (MI pretreatment: 7.9+/-1.0; MI posttreatment: 11.7+/-0.4; p < 0.05). Before placebo treatment, patients with functional dyspepsia showed increased sensitivity to stepwise distension of the stomach relative to healthy individuals. After 8 wk of placebo treatment sensitivity to distension remained unchanged, even though patients' clinical status was markedly improved. CONCLUSION In patients with functional dyspepsia, the symptomatic response to placebo is substantial. Some significant changes were also observed in gastric motility: increase in the gastric phase III number as well as in the postprandial antral motility index in those with hypomotility pretreatment. Remarkably, however, clinical improvement seems to occur independently of detectable changes in gastroduodenal motor activity or gastric hypersensitivity to distension.

Abstract
To determine whether functional dyspepsia and irritable bowel syndrome are different entities, epidemiological data, factor analysis studies, physiological data and associated psychological symptoms were reviewed. Between 30% and 60% of patients with either diagnosis also meet the criteria for the other diagnosis, a level greater than expected to occur by chance but not sufficient to infer an identity. Most factor analysis studies identify independent clusters of symptoms corresponding to functional dyspepsia and irritable bowel syndrome. Visceral hypersensitivity is seen throughout the gastrointestinal tract in both disorders, but the motility patterns seen in association with functional dyspepsia (principally antral hypomotility and delayed gastric emptying) differ from the motility patterns seen in irritable bowel syndrome. Psychological symptoms are similar in these two disorders but are not believed to be aetiological for either of them. Thus, based on a factor analysis of gastrointestinal symptoms and differences in intestinal motility, functional dyspepsia and irritable bowel syndrome appear to be different entities.

Abstract
Gastrointestinal (GI) complaints are among the most common symptoms in primary care yet are frequently unexplained and often lead to costly diagnostic testing. We sought to determine the prevalence of psychiatric disorders in patients with unexplained GI complaints undergoing upper endoscopy, and the likelihood of endoscopic abnormalities in patients with and without psychiatric diagnoses. We prospectively evaluated 116 adult patients who were undergoing upper endoscopy to evaluate GI complaints. All subjects received a structured psychiatric interview prior to endoscopy using PRIME-MD, and endoscopists were blinded to the PRIME-MD results. Psychiatric disorders were detected in 70 (60%) patients. Overall, there were 113 diagnoses (some patients had multiple disorders) with the most common being somatoform (44%), depressive (29%), and anxiety (19%) disorders. Only 29 patients had major endoscopic abnormalities, including esophageal disease (14), peptic ulcer (9), severe gastritis (4), gastric cancer (1), and esophageal cancer (1). There was a much higher prevalence of psychiatric disorders in patients without major endoscopic abnormalities (74% vs. 21%, p < 0.0001). Psychiatric disease was strongly predictive of endoscopic findings (OR for major abnormality = 0.11 in women, and 0.40 in men), especially if somatoform disorder was present (OR = 0.15). We conclude that, with a simple questionnaire, psychiatric disorders can be diagnosed in a large proportion of patients with unexplained GI complaints who are referred for upper endoscopy. The presence of a psychiatric disorder, particularly if somatoform, makes it unlikely that endoscopy will reveal significant GI disease.

Abstract
We wanted to examine the prevalence of psychiatric morbidity in patients diagnosed as having essential dyspepsia, as well as the short-term course of dyspeptic symptoms, following drug treatment of the psychiatric condition. Seventy-four patients with essential dyspepsia presenting to the gastroenterology outpatient department of a medical college were investigated for the presence of psychiatric disorder. The response to an open trial of pharmacotherapy in 50 patients with a psychiatric disorder and no other demonstrable pathology was assessed. These patients met the criteria for a DSM-III-R diagnosis, most commonly major depressive disorder (26) or generalized anxiety disorder (10). The mean age of those with a psychiatric disorder alone was significantly higher than that of those with another demonstrable pathology. With treatment, 16 patients with no demonstrable pathology other than psychiatric disorder (depression: 12; anxiety: 4) showed improvement over a period of 6 weeks in psychiatric as well as dyspepsia ratings. The difference was however statistically significant only for the group with major depressive disorder. We concluded that, despite differences in the characteristics of the population studied, a psychiatric diagnosis is associated with at least a proportion of cases with essential dyspepsia and emerges as a likely explanation.

Abstract
It has often been suggested that mood and personality predispose to peptic ulcer, but little prospective evidence exists. We used longitudinal data from the Alameda County Study to seek associations of psychological characteristics with later ulcer development, taking into account the possible confounding or mediating, taking into account the possible confounding or mediating roles of nonpsychological factors. Among 4,595 Alameda County Study subjects ulcer-free in 1965, we studied five baseline psychological measures (depression, hostility, ego resiliency, social alienation or anomy, and personal uncertainty) with respect to reported ulcer in 1973-1974. All five measures had significant age-adjusted associations with incident ulcer [odds ratio (O.R.) 1.8-2.6]. After adjustment for smoking, drinking, skipping breakfast, lack of sleep, painful medical conditions, and liver disease, three measures remained significant: depression, anomy, and hostility. The age-adjusted O.R. of 2.8 [95% confidence interval (C.I.) 1.6, 4.8] for an upper versus a lower tertile index of independently predictive psychological factors fell to 2.1 with adjustment for health-related behaviors and medical conditions, and reached 1.7 (C.I. 1.0, 3.1) after addition of education to the model. We conclude that depression, maladjustment, and hostility are prospectively associated with peptic ulcer. These associations are partially accounted for by confounding or mediation by standard risk factors, and are to some extent related to socioeconomic status.

Abstract
Seventy-five patients with recent-onset dyspepsia and endoscopically visible duodenal ulcer underwent psychological evaluation. Following ranitidine treatment, they were reinterviewed periodically for 12 to 76 months (mean 38.6). Ulcer symptoms were present during a mean of 14.9% of follow-up months. Patients did significantly worse if they had a low-status occupation, low education, depression, stressful life events, or abnormal Minnesota Multiphasic Personality Inventory at baseline. Of patients recalling premorbid life stress, those with a normal MMPI had a particularly benign course, whereas those with an abnormal MMPI did particularly poorly (6% versus 29% of months symptomatic: p < 0.04). Age, gender, smoking, drinking, antiinflammatory drugs, pepsinogen, Helicobacter pylori titers, and initial healing had no prognostic effect. Low socioeconomic status, life stress, depression, and psychopathology each predict a relatively poor symptom outcome for duodenal ulcer treated with antisecretory therapy, but psychologically stable individuals who develop an ulcer under stress have an excellent long-term prognosis.

Abstract
Increased numbers of psychiatric diagnoses and increased levels of psychological distress are seen in the majority of medical clinic patients with gastrointestinal motility disorders. In IBS, psychological symptoms are believed to be comorbid conditions, which do not cause the motility disorder but which do influence the patient's decision to consult a physician. In functional dyspepsia, psychological symptoms are present in many patients, but their role is not known; the available data suggest that psychological symptoms do not predict which patients will consult a physician. Among constipated patients, anxiety is believed to contribute to the development and course of pelvic floor dyssynergia by increasing pelvic floor muscle tension. Constipated patients without physiologic abnormalities to explain their constipation appear to have more psychological symptoms than those with delayed colonic transit, but there is significant psychological distress even in patients with slow transit constipation. Psychological symptoms do not seem to predict which constipated patients will consult a physician. There is an increased incidence of psychiatric diagnoses in patients with esophageal motility disorders as well, but the role that these psychological symptoms play in the course of the disorder is not known. Patients with the most common gastrointestinal motility disorders, IBS and dyspepsia, report experiencing more stressful life events, and IBS patients appear to show a greater increase in gastrointestinal symptoms when exposed to stressors. Laboratory studies document that acute psychological stressors do alter gastric, small bowel, and colonic motility, and patients with IBS appear to show a greater change in colonic and ileal motility with stress than healthy controls. Greater reactivity has not been demonstrated for the esophagus or stomach, however, and it has not been demonstrated for other gastrointestinal motility disorders. A characteristic of many patients who consult gastroenterologists for IBS and other motility disorders is a tendency to report multiple somatic complaints (including many nongastrointestinal complaints) and to overuse medical resources. This pattern of behavior is referred to as somatization or abnormal illness behavior. One source of abnormal illness behavior is childhood social learning, which occurs (1) when parents provide gifts or special privileges to a child who reports somatic symptoms or (2) when parents model abnormal illness behaviors themselves.

Abstract
BACKGROUND Life events and stress may be important for functional dyspepsia and duodenal ulcer. METHODS The perception of life events in the preceding 6 months was recorded in 100 patients with functional dyspepsia, 100 patients with duodenal ulcer, and 100 healthy controls. In addition, psychologic and social factors were assessed. RESULTS Patients with functional dyspepsia experienced significantly more life events than patients with duodenal ulcer and healthy controls. The difference in life events between the groups was due to the difference in stressful life events. The patients with functional dyspepsia had higher levels of state-trait anxiety, general psychopathology, and depression than patients with duodenal ulcer and healthy controls. CONCLUSION Patients with functional dyspepsia had higher scores on negative life events than patients with duodenal ulcer and healthy controls. This may be causally related to the higher levels of anxiety, depression, and general psychopathology in these patients.

Abstract
Twenty-five patients, 12 men and 13 women, aged 24-50 yr, who had consulted physicians and had received the diagnosis functional dyspepsia after extensive examination 6-8 years prior to this study, and were still suffering from this condition, were compared with community control subjects pair-wise matched for age and sex. Control subjects who had ever consulted a physician for gastrointestinal symptoms were excluded. Questionnaires measuring symptoms, job strain, social support and personality traits were used. Relatively few differences were found between groups. Compared to the community controls, however, the patients reported more gastrointestinal and nervous symptoms, and higher somatization, measured by Symptom Check List-90. The extent of reported overall distress was greater in patients than in control subjects. The detachment score (Karolinska Scales of Personality) was significantly lower in patients than in control subjects; this difference was also significant in separate analysis for men. Female patients had lower socialization and higher suspicion scores than female control subjects. Male patients reported more decision latitude (job control) than male control subjects.

Abstract
Patients with functional dyspepsia were assigned at random to cognitive psychotherapy (10 sessions of 50 min duration, n = 50) or to a control group (no treatment, n = 50). Before treatment all patients were assessed on psychological, somatic and lifestyle factors. If allocated to the therapy group all patients were also asked to define the main problems they wanted to discuss in therapy ('target complaints'). The patients were evaluated at the end of therapy (after 4 months) and at 1 yr follow-up. Outcome measures were dyspeptic symptoms, scores on 'target complaints' and psychological parameters. Both groups showed improvement in dyspeptic and psychological parameters after 1 yr. The improvement in the control group was attributed to a non- specific effect of increased interest and attention. The therapy group showed greater reduction than the control group on dyspeptic symptoms [days of epigastric pain (p = 0.050), nausea (p = 0.024), heartburn (p = 0.021), diarrhoea (p = 0.002) and constipation (p = 0.047)]; and on scores on 'target complaints' (p = 0.001).

Abstract
One hundred patients with functional dyspepsia, 100 patients with duodenal ulcer and 100 healthy controls were assessed on anamnestic factors, somatic symptoms and psychological measures. Patients with functional dyspepsia had significantly higher levels of state-trait anxiety, general psychopathology, depression, a lower general level of functioning and more somatic complaints from different organ systems, especially the musculo-skeletal system, compared to patients with duodenal ulcer and healthy controls. Patients with functional dyspepsia had more frequent dyspepsia symptoms and a longer disease history than duodenal ulcer patients. Discriminant analyses using a model of fifteen psychological and anamnestic variables, classified correctly 71.5% of the subjects due to diagnoses. The test for multiple somatic complaints (Giessener Beschwerdebogen) was the most important discriminating factor (Eigenvalue 0.78). Seventy-five per cent of the patients were correctly classified, 71% by diagnosis with respect to diagnoses of duodenal ulcer and functional dyspepsia using frequency of dyspeptic symptoms as discriminating factor (Eigenvalue 0.40). Functional dyspepsia seems to be a disease entity of its own, distinct from duodenal ulcer and strongly associated with psychological factors.

Abstract
Questionnaire data based on traditional concepts for measuring hypochondriasis and depression were related to serological data on Helicobacter pylori antibodies in 110 of 130 consecutive patients, aged 18-65 yr, consulting for dyspeptic symptoms in general practice. Of the patients thirty-seven (33.6%) and seventy-three (66.4%) were classified as H. pylori positives and H. pylori negatives, respectively, the H. pylori positive patients being significantly older than H. pylori negative patients. Factor analyses of the questionnaire data indicated the heterogeneity of each of the traditional concepts for measuring hypochondriasis and depression but succeeded in differentiating orthogonally between two hypochondriasis factors and three depression factors. Hierarchical regression analyses of factor scores, controlling for the influence of age and sex, indicated higher H. pylori antibody activity to be associated with less hypochondriacal signs of anxiety and uneasiness. It is hypothesized, that in dyspepsia without signs of H. pylori infection, somatization may account to a substantial extent for the illness.

Abstract
Burning mouth syndrome--BMS (also known as glossodynia, glossalgia, glossopyrosis, or oral dysesthesia)--primarily affects middle-aged women. Many possible etiologies have been proposed to account for the syndrome; most are still unsubstantiated. One possible suggested etiology involves the presence of psychological components. In this study, 45 BMS patients and 45 age-, sex-, ethnic origin-, socio-economic status-, and education-matched control subjects were evaluated for their psychopathologic profile and existence of recent life events. All subjects were requested to complete the SCL-90 questionnaire and a Recent Life Changes questionnaire. The BMS patients scored significantly higher on all SCL-90 scales except one. A MANOVA test to evaluate the overall group effect was significant at the 0.0001 level. No differences between groups were found for recent life events. The data suggest that although BMS patients are subjected to elevated psychological stress, initiation of BMS symptoms is not necessarily correlated with stressful life events.

Abstract
The prevalence, incidence, natural history, and risk factors of upper dyspepsia (UD) were evaluated in a random sample of Danes. Of the 4581 eligible subjects, 79% responded. Five years later 85% of the survivors attended a similar follow-up study. Depending on the frequency of the symptoms, the prevalence of UD was 13-54% among men and 15-47% among women, and the incidence was 5-22% and 6-25%, respectively. Five years later 26-69% of subjects with UD were free from symptoms. As an independent factor psychic vulnerability was most strongly related to prevalence and incidence of UD, whereas experience of problems, smoking, and body mass index were only weakly associated with prevalence of UD. A comparison of the populations identified by various definitions of UD showed that these populations had rather few subjects in common. In conclusion, UD occurs frequently and fluctuates in the general population. Only psychic vulnerability was strongly related to UD incidence. The syndrome, however, still needs to be verified as a disease entity.
