Xiaoyaosan Exerts Therapeutic Effects on the Colon of Chronic Restraint Stress Model Rats via the Regulation of Immunoinflammatory Activation Induced by the TLR4/NLRP3 Inflammasome Signaling Pathway. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:6673538. [PMID: 33505499 PMCID: PMC7810549 DOI: 10.1155/2021/6673538] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Revised: 11/28/2020] [Accepted: 12/17/2020] [Indexed: 11/23/2022]
Abstract
Depression is the neurological manifestation most commonly associated with gastrointestinal diseases. The release of inflammatory cytokines mediated by TLR4/NLRP3 inflammasome signaling-induced immunoinflammatory activation may represent a common pathogenic process underlying the development of gastrointestinal diseases and depression. Clinical studies have indicated that Xiaoyaosan (XYS) can relieve depressive behavior by improving gastrointestinal symptoms. We previously demonstrated that XYS can reduce colonic inflammation in a rat model of chronic unpredictable mild stress; however, the precise anti-inflammatory mechanisms involved remain unclear. Here, we investigated whether XYS can ameliorate depressive behavior through regulating the TLR4/NLRP3 inflammasome signaling pathway, thereby inhibiting immunoinflammatory activation and reducing colonic proinflammatory cytokine levels. Fifty-two healthy male Sprague–Dawley rats were randomly divided into four groups (control, model, XYS, and fluoxetine). The latter three groups were subjected to 21 days of chronic restraint stress to generate a model of stress-induced depression. XYS and fluoxetine were administered intragastrically. Behavioral changes in the rats were assessed after 21 days. Serum and colon samples were collected, and the relative levels of the inflammation indicators IL-6, IL-1β, and TNF-α were determined by ELISA. Pathological changes in colon tissue were assessed by hematoxylin and eosin staining. The levels of TLR4, MyD88, NF-κB-p65, TAK1, IRAK1, and TRAF6 were detected by immunohistochemistry, while the gene and protein expression levels of TLR4, MyD88, NF-κB-p65, TAK1, IRAK1, TRAF6, NLRP3, ASC, and caspase-1 were detected by quantitative polymerase chain reaction (qPCR) and Western blotting. The results indicated that XYS could improve the depressive-like behavior and the weight loss of rats with stress-induced depression. Furthermore, depressed rats treated with XYS exhibited decreased expression levels of TLR4, MyD88, NF-κB-p65, TAK1, IRAK1, TRAF6, NLRP3, ASC, and caspase-1 in colonic tissue; reduced colon and serum concentrations of the inflammatory factors IL-6, IL-1β, and TNF-α; and lowered levels of colonic inflammation.

Abstract
Background Physical and mental health of workers is threatened due to various events and chronic occupational stress. This study was conducted to investigate the relationship between occupational stress and gastric disease in male workers of the shipbuilding industry. Methods Occupational stress measured among a total of 498 workers of a shipbuilding firm who visited the hospital for health examination using the Korean Occupational Stress Scale (KOSS)-short form, and the relationship between sociodemographic factors, health-related behaviors, occupational stress, and gastric disease, and the distribution of occupational stress by sociodemographic factors in the gastric disease group was examined. Results There was no significant association between gastric disease and total occupational stress score and its seven sub-factors. The analysis showed that risk of gastric disease was significantly higher in the Q1 group in which the stress caused by occupational discomfort among seven sub-factors was lowest than that in the Q4 group (odds ratio, 2.819; 95% confidence interval, 1.151 to 6.908). Analysis only on the gastric disease group showed that the stress score of laborers was higher in the four sub-factors than that of office workers (P < 0.05). Analysis on educational background showed that the scores of the three sub-factors were lower in subjects who's highest level of education was high school (P < 0.01). Conclusion This study suggests that it is necessary to improve the culture of Korean collectivism in the workplace and to manage the occupational stress in the low-educated and laborers. It is recommended for future studies to confirm the causal relationship between occupational stress and gastric disease by large scale studies using a KOSS which appropriately reflects workplace culture.

Abstract
AIMS A disturbance of the brain-gut axis is a prominent feature in functional bowel disorders (such as irritable bowel syndrome and functional dyspepsia) and psychological abnormalities are often implicated in their pathogenesis. We hypothesized that psychological morbidity in these conditions may result from gastrointestinal problems, rather than causing them. METHODS Functional dyspepsia was induced by neonatal gastric irritation in male rats. 10-day old male Sprague-Dawley rats received 0.1% iodoacetamide (IA) or vehicle by oral gavage for 6 days. At 8-10 weeks of age, rats were tested with sucrose preference and forced-swimming tests to examine depression-like behavior. Elevated plus maze, open field and light-dark box tests were used to test anxiety-like behaviors. ACTH and corticosterone responses to a minor stressor, saline injection, and hypothalamic CRF expression were also measured. RESULTS Behavioral tests revealed changes of anxiety- and depression-like behaviors in IA-treated, but not control rats. As compared with controls, hypothalamic and amygdaloid CRF immunoreactivity, basal levels of plasma corticosterone and stress-induced ACTH were significantly higher in IA-treated rats. Gastric sensory ablation with resiniferatoxin had no effect on behaviors but treatment with CRF type 1 receptor antagonist, antalarmin, reversed the depression-like behavior in IA-treated rats CONCLUSIONS The present results suggest that transient gastric irritation in the neonatal period can induce a long lasting increase in depression- and anxiety-like behaviors, increased expression of CRF in the hypothalamus, and an increased sensitivity of HPA axis to stress. The depression-like behavior may be mediated by the CRF1 receptor. These findings have significant implications for the pathogenesis of psychological co-morbidity in patients with functional bowel disorders.

Abstract
Introduction Psychiatric comorbidity is common in patients with functional dyspepsia (FD) but a good screening tool for psychiatric disorders in gastrointestinal clinical practice is lacking. Aims 1) Evaluate the performance and optimal cut-off of 12-item General Health Questionnaire (GHQ-12) as a screening tool for psychiatric disorders in FD patients; 2) Compare health-related quality of life (HRQoL) in FD patients with and without psychiatric comorbidities. Methods Consecutive patients fulfilling Rome III criteria for FD without medical co-morbidities and gastroesophageal reflux disease were recruited in a gastroenterology clinic. The followings were conducted at 4 weeks after index oesophagogastroduodenoscopy: self-administrated questionnaires on socio-demographics, dyspeptic symptom severity (4-point Likert scale), GHQ-12, and 36-item short-form health survey (SF-36). Psychiatric disorders were diagnosed with Structured Clinical Interview for DSM-IV Axis I Disorders (SCID) by a trained psychiatrist, which served as reference standard. Results 55 patients underwent psychiatrist-conducted interview and questionnaire assessment. 27 (49.1%) had current psychiatric disorders as determined by SCID (anxiety disorders: 38.2%, depressive disorders: 16.4%). Receiver operating characteristic curve analysis of GHQ-12 revealed an area under curve of 0.825 (95%CI: 0.698-0.914). Cut-off of GHQ-12 at ≥3 gave a sensitivity of 63.0% (95%CI = 42.4-80.6%) and specificity of 92.9% (95%CI = 76.5%-98.9%). Subjects with co-existing psychiatric disorders scored significantly lower in multiple domains of SF-36 (mental component summary, general health, vitality and mental health). By multivariate linear regression analysis, current psychiatric morbidities (Beta = -0.396, p = 0.002) and family history of psychiatric illness (Beta = -0.299, p = 0.015) were independent risk factors for poorer mental component summary in SF-36, while dyspepsia severity was the only independent risk factor for poorer physical component summary (Beta = -0.332, p = 0.027). Conclusions Concomitant psychiatric disorders adversely affect HRQoL in FD patients. The use of GHQ-12 as a reliable screening tool for psychiatric disorders allows early intervention and may improve clinical outcomes of these patients.

Abstract
Background Treatment objectives for dyspepsia include improvements in both symptoms and health-related quality of life (HRQoL). There is a lack of disease-specific instruments measuring HRQoL in South East Asian dyspeptics. Objectives To validate English and locally translated version of the Short-Form Nepean Dyspepsia Index (SF-NDI) in Malaysian patients who consult for dyspepsia. Methods The English version of the SF-NDI was culturally adapted locally and a Malay translation was developed using standard procedures. English and Malay versions of the SF-NDI were assessed against the SF-36 and the Leeds Dyspepsia Questionnaire (LDQ), examining internal consistency, test-retest reliability and construct validity. Results Pilot testing of the translated Malay and original English versions of the SF-NDI in twenty subjects did not identify any cross-cultural adaptation problems. 143 patients (86 English-speaking and 57 Malay speaking) with dyspepsia were interviewed and the overall response rate was 100% with nil missing data. The median total SF-NDI score for both languages were 72.5 and 60.0 respectively. Test-retest reliability was good with intraclass correlation coefficients of 0.90 (English) and 0.83 (Malay), while internal consistency of SF-NDI subscales revealed α values ranging from 0.83 – 0.88 (English) and 0.83 – 0.90 (Malay). In both languages, SF-NDI sub-scales and total score demonstrated lower values in patients with more severe symptoms and in patients with functional vs organic dyspepsia (known groups validity), although these were less marked in the Malay language version. There was moderate to good correlation (r = 0.3 – 0.6) between all SF-NDI sub-scales and various domains of the SF-36 (convergent validity). Conclusion This study demonstrates that both English and Malay versions of the SF-NDI are reliable and probably valid instruments for measuring HRQoL in Malaysian patients with dyspepsia.

Abstract
OBJETIVO: Avaliar a associação entre depressão e dispepsia funcional. PACIENTES E MÉTODOS: Estudo transversal onde foram avaliados 348 pacientes com diagnóstico de dispepsia no Ambulatório de Gastroenterologia do Hospital Universitário de Pelotas, RS, cidade de médio porte do sul do Brasil, durante o período de 1 ano (de março de 2001 a março de 2002). Após o diagnóstico de dispepsia avaliou-se a presença de depressão, tanto em pacientes com dispepsia funcional, quanto naqueles com dispepsia orgânica. Utilizou-se a análise univariada para descrição das freqüências das variáveis de interesse e da análise bivariada, com o teste qui-quadrado, para comparação entre proporções das variáveis categóricas. A técnica da regressão logística foi utilizada para estabelecer a chance dos pacientes com depressão apresentarem dispepsia funcional e para controlar o efeito das variáveis intervenientes sobre a variável de desfecho RESULTADOS: Evidenciaram maior prevalência de deprimidos entre os pacientes com dispepsia funcional (30,4%) em relação àqueles com dispepsia orgânica (11,2%). As mulheres apresentaram maior chance de dispepsia funcional (OR: 1,74, IC 95%, 1,05-2,89) e, em relação à idade, os intervalos entre 31 e 50 anos (OR: 0,28 IC 95%, 0,13-0,54) e de 51 a 60 anos (OR: 0,41, IC 95%, 0,17-0,96) mostraram efeito protetor, ou seja, indivíduos nessas faixas etárias têm menor risco de apresentar dispepsia funcional. Após a análise multivariada, pacientes deprimidos apresentaram chance três vezes maior de co-morbidade com dispepsia funcional do que pacientes não-deprimidos (OR 3,13; IC 95%; 1,71-5,74).

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
OBJECTIVE Using an experimental paradigm this investigation explored whether exposure to psychological stress would produce a significant increase in acid-reflux episodes or modify subjective perceptions of gastro-oesophageal reflux (GOR) symptoms. METHODS Forty-two patients presenting with heartburn and acid regurgitation underwent 24-h oesophageal pH monitoring. During the last 90 min of this monitoring period, 21 patients received a psychological stressor, while the remaining participants were randomly assigned to a no-stress control condition. State anxiety and subjective GOR symptom ratings were obtained 1 min pretest, 1 min posttest, and 40 min posttest. Cortisol samples were collected at 10-min intervals. RESULTS The stressor induced a significant increase in cortisol and state anxiety; however, this was not associated with any increase in reflux. Instead, the experimental group reported a dissociation between objectively measured reflux episodes and subjective symptom ratings. A similar pattern was established for participants who reported greater state anxiety, produced larger cortisol responses, or exhibited certain stress-related personality characteristics. CONCLUSION The perception of symptoms in the absence of increased reflux when one is stressed may account for low response rates to traditional treatments. This highlights a need to bridge the gap between psychosomatic research and clinical practice to develop more successful GOR therapies.

Abstract
BACKGROUND Limited information is available about anxiety, depression and psychotropic medication use in patients referred for gastrointestinal endoscopy. AIM To determine anxiety and depression and its association with endoscopic findings in a representative sample of patients with persistent gastrointestinal symptoms prior to endoscopy. METHODS Patients referred to the hospital for endoscopy between February 2002 and February 2004 were asked to score anxiety and depression on the Hospital Anxiety and Depression Scale 2 weeks prior to endoscopy. Information about endoscopic diagnoses was obtained from medical files. RESULTS A total of 1298 subjects was studied (600 upper gastrointestinal endoscopies and 698 lower gastrointestinal endoscopies). Patients referred for upper gastrointestinal endoscopy used most psychotropic agents (24%; odds ratio = 3.1; 95% confidence interval = 2.3-4.2), especially patients with an organic abnormality when compared with patients without an organic abnormality (42% versus 8%; odds ratio = 8.6; 95% confidence interval = 5.4-14.0). Patients with colonic polyps were more anxious (odds ratio = 1.7; 95% confidence interval = 1.0-2.9) and depressed (odds ratio = 1.8; 95% confidence interval = 1.1-3.1) than other patients referred for lower gastrointestinal endoscopy. CONCLUSIONS There is no difference in anxiety nor depression between patients with and without organic abnormalities at endoscopy. Patients with colonic polyps are more anxious and depressed than other patients referred for lower gastrointestinal endoscopy. Psychotropic medication use is highest among patients with an organic abnormality in the proximal gastrointestinal tract.

Abstract
AIM: To investigate the abnormity of rat colon caused by depression and the ameliorative effects of Radix Acanthopanacis Senticosi (RAS) capsule on colon and their mechanisms in rat depression model.
METHODS: Chronic stress-induced model of depression of Wistar rats was produced. The experimental animals were randomly divided into model control, 5-aminosalicylic acid (5-ASA) therapy group and three RAS capsule therapy groups. These five groups were intracolonically treated daily (8:00 a.m.) for 2 wk with normal saline, 5-ASA (100 mg/kg) and RAS capsule at the doses of 300, 600 and 900 mg/kg, respectively. A normal control group of rats was also included in the study. Colonic activities of nitric oxide (NO) and superoxide dismutase (SOD), levels of malondialdehyde (MDA) and inducible nitric oxide synthase (iNOS) were determined by ultraviolet spectrophotometry. The expression of cyclooxygenase-2 (COX-2) in colonic tissue was detected by immunohistochemistry.
RESULTS: Enhanced colon inflammatory response and oxidative stress were observed in the chronic stress-induced rat depression model, which manifested as the significant increase of MDA, iNOS and NO levels, as well as the expressions of COX-2 in the colon tissue, but the colonic SOD activity was significantly decreased compared with the normal control (MDA: 10.34±2.77 vs 2.55±0.70; iNOS: 1.11±0.44 vs 0.25±0.16; COX-2: 53.26±8.16 vs 4.87±1.65; NO: 11.28±5.66 vs 4.76±1.55; SOD: 53.39±11.15 vs 84.45±22.31; P<0.01). However, these parameters were significantly ameliorated in rats treated locally with RAS capsule at the doses of 300, 600 and 900 mg/kg (iNOS: 0.65±0.31, 0.58±0.22 and 0.64±0.33; NO: 5.99±2.73, 6.87±1.96 and 6.50±1.58; MDA: 2.92±0.75, 3.19±1.08 and 3.26±1.24; SOD: 70.81±12.36, 73.30±15.30 and 69.09±11.03, respectively). The expressions of COX-2 in the colon were significantly ameliorated (28.83±9.48 and 27.04±9.56, respectively) when RAS capsule was administered at the doses of 600 and 900 mg/kg.
CONCLUSION: Administration of RAS capsule intracolonically may have significant therapeutic effects on the colon of rat depression model, which are probably due to its antioxidative action and inhibition of arachidonic acid metabolism.

Abstract
AIM: Population-based assessment of noncardiac chest pain (NCCP) is lacking. The aim of this study was to evaluate the prevalence, psychosocial factors and health seeking behaviour of NCCP in southern Chinese.
METHODS: A total of 2209 ethnic Hong Kong Chinese households were recruited to participate in a telephone survey to study the epidemiology of NCCP using the Rose angina questionnaire, a validated gastroesophageal reflux disease (GERD) questionnaire and the hospital anxiety-depression scale. NCCP was defined as non-exertional chest pain according to the Rose angina questionnaire and had not been diagnosed as ischaemic heart diseases by a physician.
RESULTS: Chest pain over the past year was present in 454 subjects (20.6%, 95%CI 19-22), while NCCP was present in 307 subjects (13.9%, 95%CI 13-15). GERD was present in 51% of subjects with NCCP and 34% had consulted a physician for chest pain. Subjects with NCCP had a significantly higher anxiety (P < 0.001) and depression score (P = 0.007), and required more days off (P = 0.021) than subjects with no chest pain. By multiple logistic regression analysis, female gender (OR 1.9, 95%CI 1.1-3.2), presence of GERD (OR 2.8, 95%CI 1.6-4.8), and social life being affected by NCCP (OR 6.9, 95%CI 3.3-15.9) were independent factors associated with health seeking behaviour in southern Chinese with NCCP.
CONCLUSION: NCCP is a common problem in southern Chinese and associated with anxiety and depression. Female gender, GERD and social life affected by chest pain were associated with health care utilization in subjects with NCCP.

Abstract
BACKGROUND AND AIMS The natural history of functional dyspepsia is not well known. We prospectively assess the quality of life and severity of symptoms in a group of Spanish patients with functional dyspepsia. PATIENTS AND METHODS One hundred and twelve consecutive patients with functional dyspepsia, according to Rome II criteria, were prospectively followed up for 1 year. All patients completed symptom (Dyspepsia Questionnaire and the Gastrointestinal Symptoms Rating Scale) and quality of life [the Psychological General Well-Being (PGWB) Index and the General Health Questionnaire (GHQ)] questionnaires every 3 months. Only free antacid consumption was permitted during the study period. RESULTS The group was made up of 81 women and 31 men with a mean age of 45 +/- 17 years; 66% of patients were infected with Helicobacter pylori, and ulcer-like dyspepsia (53%) was the predominant subgroup. At baseline, quality of life scores were low (PGWB, 87.1 +/- 17.6 and GHQ, 20.6 +/- 11.8), but these values gradually improved during the year of follow-up (PGWB, 107.7 +/- 1.1 and GHQ, 8.9 +/- 0.4). Digestive symptoms also decreased. In the multivariate analysis, the anxiety score on the PGWB index (Wald, 5.2; P = 0.02) and smoking status (Wald, 4.3; P = 0.04) were predictors of end quality of life. At baseline, patients with a high level of anxiety had a very reduced quality of life, although their symptom scores were similar to other patients. CONCLUSION Quality of life is reduced in patients with functional dyspepsia. Some improvement in quality of life together with a decrease in the severity of symptom scores was seen during the 1 year of follow-up. We believe that both the reassurance of negative endoscopy and the scheduling of visits to the doctor favourably influence the quality of life.

Abstract
In functional dyspepsia, abnormal intragastric distribution of a test meal has been identified but has never been correlated to any symptom pattern. The aim of this study was to compare the intragastric distribution of a meal between functional dyspepsia patients and controls, and to correlate distribution with symptom patterns, using scintigraphic gastric emptying studies. In forty patients with functional dyspepsia and 29 healthy volunteers, scintigraphic planar images were obtained immediately after ingestion of a mixed radiolabelled test meal and every 20 min for 2 h. The images of the stomach were divided into proximal and distal compartments. The mean intragastric distribution was similar in patients and controls. Over the whole test, 18 (45%) and 20 (50%) patients had a distal redistribution of the solid and liquid phase of the meal, respectively, while proximal retention of these phases was found in 13 (33%) and 9 (23%) patients. Early satiety was associated with early distal redistribution of the liquid phase and fullness was associated with late proximal retention. This study shows similar intragastric distribution of a test meal in health and functional dyspepsia. Within the patient group, an association between abnormal intragastric distribution patterns and symptom profiles was found, which might be related to different pathophysiological mechanisms.

Abstract
BACKGROUND & AIMS Categorization of functional dyspepsia into subgroups is based on expert opinion according to (dominant) symptoms or on underlying pathophysiological mechanisms. We used an evidence-based approach to the determination of subtypes of functional dyspepsia. METHODS Consecutive functional dyspepsia patients were recruited from a tertiary referral center. The following were performed: (1) exploratory (EFA) and confirmatory factor analysis (CFA) of symptom patterns in a large group of patients with functional dyspepsia; (2) external validation of these factors by the determination of their association pattern with physio- and psychopathological mechanisms, and with health-related quality of life and sickness behavior; and (3) cluster analysis of their distribution in this population. RESULTS Both EFA and CFA do not support the existence of functional dyspepsia as a homogeneous (unidimensional) condition. A 4-factor model is found to be valid, with differential distribution within the patient population according to cluster analysis. Factor 1 is characterized by nausea, vomiting, early satiety, and weight loss and factor 2 by postprandial fullness and bloating. Both factor 1 and 2 are associated with delayed emptying, but only factor 1 is associated with younger age, female sex, and sickness behavior. Factor 3 is characterized by pain symptoms and associated with gastric hypersensitivity and several psychosocial dimensions including medically unexplained symptoms and health-related quality of life dimensions. Factor 4, characterized by belching, is also associated with hypersensitivity, but is unrelated to psychosocial dimensions. CONCLUSIONS In a tertiary care population, functional dyspepsia is a heterogeneous condition characterized by 4 major dimensions differentially associated with psychopathological and physiopathological mechanisms.

Abstract
Dyspepsia is a common symptom. Dyspeptic symptoms may be caused by a variety of conditions such as peptic ulcer disease, gastro-oesophageal reflux, and malignancy. Most often, however, no cause is identified and dyspepsia is deemed to be functional. While symptom severity does influence frequency of consultation, dyspeptic consulters also differ from non-consulters with respect to symptom perception and anxiety. This highlights the importance of understanding the patient's agenda early in the course of evaluation. Patients over the age of 55 years or with alarm symptoms should be referred for prompt endoscopy. In the absence of other clinically apparent aetiologies, uninvestigated dyspeptics can be either tested and treated for Helicobacter pylori or empirically treated with proton pump inhibitors. Uninvestigated dyspeptics failing empiric therapy should be referred for evaluation that includes endoscopy. Further therapy with prokinetics, tricyclic antidepressants, fundal relaxants, antidepressants, or psychotherapy is guided by predominant symptoms and assessment of possible psychiatric factors.

Abstract
AIMS To study the prevalence of dyspepsia and irritable bowel syndrome and the effects of co-existing anxiety and depression on health care utilization by a population survey in Chinese. METHODS Ethnic Chinese households were invited to participate in a telephone survey using a validated bowel symptom questionnaire and the hospital anxiety and depression scale. Gastrointestinal symptoms were classified as dyspepsia and irritable bowel syndrome according to the Rome I criteria and gastro-oesophageal reflux disease by the presence of weekly heartburn or acid regurgitation. The anxiety and depression scores were compared between patients who sought medical attention and those who did not, using multiple logistic regression analysis. RESULTS One thousand, six hundred and forty-nine subjects completed the interview (response rate, 62%). The population prevalences of dyspepsia, irritable bowel syndrome and gastro-oesophageal reflux disease were 18.4%, 4.1% and 4.8%, respectively. Dyspepsia and irritable bowel syndrome were associated with anxiety, depression, medical consultation, sick leave and adverse effects on social life. The degree of anxiety was an independent factor associated with health care-seeking behaviour in both dyspeptics (P = 0.003) and irritable bowel syndrome patients (P = 0.036). CONCLUSIONS Irritable bowel syndrome and dyspepsia are associated with anxiety, depression, significant social morbidity, health care utilization and days off work. Anxiety is an independent factor in determining health care utilization in patients with dyspepsia and irritable bowel syndrome.

Abstract
Functional dyspepsia is a clinical syndrome defined by upper abdominal symptoms without identifiable cause by conventional diagnostic means. Recent studies have established that functional dyspepsia is a heterogeneous disorder in which different pathophysiologic disturbances underlie different symptom profiles. Delayed gastric emptying is associated with postprandial fullness, nausea, and vomiting; impaired accommodation is associated with early satiety and weight loss; and hypersensitivity to gastric distention is associated with epigastric pain, belching, and weight loss. The pathogenesis of functional dyspepsia is unknown but may be postinfectious in a subgroup of patients. The role of psychological disturbances and of duodenal hypersensitivity requires further study. Treatment of the underlying pathophysiologic abnormality seems logical, but options for pharmacotherapy are limited to acid suppression, prokinetic drugs, and antidepressants. Psychotherapy can be considered for refractory patients. Several novel drug therapies are under evaluation.

Abstract
Psychologic factors in functional dyspepsia have been discussed in many previous articles. However, the relationship between depression and functional dyspepsia is still obscure. We investigated the impact of depression on clinical symptoms and gastric dysrhythmia in functional dyspepsia. Thirty-nine patients with functional dyspepsia and 18 healthy subjects were included. Patients were investigated with clinical symptoms assessment, Zung's self-rating depression scale, and electrogastrography. Patients with functional dyspepsia were divided into two groups: 21 patients with depression and 18 patients without depression. The depressed patients had similar total gastrointestinal symptom severity scores compared with the nondepressed patients, but with higher total symptom frequency scores (p < 0.05). With regards to symptoms, the depressed patients had higher abdominal fullness severity and frequency scores and nausea frequency scores. The patients with functional dyspepsia had a lower percentage of normal slow wave in both the fasting and fed states and a higher percentage of bradygastria in the fasting state and tachygastria in the postprandial state (p < 0.05). There was no significant difference in the percentage of bradygastria or tachygastria between the depressed and nondepressed patients. There was no correlation between the specific type of electrogastrographic abnormality and the presence or absence of depression in functional dyspepsia patients.

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
Lack of endoscopic esophagitis does not exclude gastroesophageal reflux disease (GERD). Ambulatory pH testing is also an imperfect standard, and patients with both a normal endoscopy and a normal pH test may still have symptoms produced by acid reflux. A therapeutic trial of acid suppression is often the best approach to these patients. Ideally, therapeutic trials should use a medication with a high degree of efficacy in the treatment of GERD to avoid a false-negative test. Proton pump inhibitors (PPIs) are the best currently available medical therapy for all forms of GERD. If the patient does not respond to a once daily PPI, options include increasing the dose of PPIs, and, perhaps, adding another class of agent or studying the patient with an ambulatory pH test. Patients with a negative endoscopy, negative pH test. and those who do not respond to an adequate trial of acid suppression are unlikely to benefit from antireflux surgery.

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
Up to 35% of the world population suffer from functional gastrointestinal disorders (FGD), accounting for about 40% of gastroenterologic and 12% of primary care practice. Society incurs high costs from FGD morbidity in terms of medical workups and absenteeism from work. FGD are characterized by chronic and recurrent symptoms of the gastrointestinal (GI) tract without detectable structural or biochemical abnormalities. In the absence of universal biologic markers, the diagnosis is based on consensus symptom criteria (1). This chapter reviews current knowledge of the pathophysiology and provides a practical approach to patients with functional dyspepsia and irritable bowel syndrome, 2 of the most common functional GI syndromes.

Abstract
This study examined the prevalence of functional gastrointestinal (FGI) disorders, and the association between FGI disorders and measures of affective distress, among a sample of 127 university students. Subjects completed a questionnaire battery including Research Diagnostic Questions for Functional Gastrointestinal Disorders, the Beck Anxiety Inventory, the Anxiety Sensitivity Index, the Beck Depression Inventory, and a medical utilization questionnaire. FGI disorders were diagnosed in 51.2% of the sample. Functional dyspepsia (22.8%), dyschezia (20.5%), functional heartburn (19.7%), functional chest pain (18.1%), and globus (12.6%) were the most frequently diagnosed disorders. Participants experiencing globus, functional dyspepsia, or functional heartburn showed significant differences in terms of anxiety, anxiety sensitivity, depression, and/or physician visits, when compared with participants without these disorders. Our results suggest that FGI disorders are strikingly prevalent among young adults, and specific FGI disorders are associated with affective distress. Implications of the observed association between psychological factors and FGI disorders are discussed.

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
BACKGROUND It is unclear whether normal endoscopy results in patients investigated for dyspepsia has therapeutic value. Therefore the aim of this study was to evaluate the effect of the endoscopy on quality of life and dyspeptic symptoms. METHODS One hundred ninety-six symptomatic patients (85 men and 111 women, mean age 42.9 years), who were receiving no treatment, were investigated before and 1 week after endoscopy with the use of a battery of validated questionnaires. RESULTS Before endoscopy the health-related quality of life was compromised in comparison with a normal population, but 1 week after a negative endoscopy it is increased to a level which was close to the normal range despite no major change in symptoms. Physical activity and sleep scores improved significantly after endoscopy. CONCLUSION The present results suggest that a negative endoscopy improves quality of life in the short-term in patients with dyspepsia, even though symptoms may persist.

Abstract
Dyspepsia, defined as "pain or discomfort centered in the upper abdomen" is reported by one in four adults in Western societies. The most important causes are non-ulcer (functional) dyspepsia, peptic ulcer, gastroesophageal reflux, and, rarely, gastric cancer. Persons with heartburn alone are not considered to have dyspepsia. The division of dyspepsia into symptom-based subgroups (ulcer-like, dysmotility-like, reflux-like, and unspecified dyspepsia) has proven to be of doubtful value for the clinician, as it has a low predictive value for identifying the causes of dyspepsia. Upper endoscopy remains the "gold standard" test; ultrasound and blood tests have a low yield. The role of Helicobacter pylori in peptic ulcer disease is well known, but the clinical role of the infection in non-ulcer dyspepsia remains very controversial. In uninvestigated dyspeptic patients who are H. pylori infected based on a non-invasive test, empiric anti-H. pylori therapy is a reasonable and probably cost-effective option. In documented non-ulcer dyspepsia, prokinetics are superior to placebo while antisecretory therapy is of less certain efficacy.

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
This article has summarized the epidemiology of several disorders commonly seen in a gastroenterologist's practice. The emphasis has been on population-based data because many people with these disorders never seek health care, and psychological features have been shown to be strongly associated with health care-seeking behavior. Each of these disorders is common in the community; in fact, the majority of the population experiences intermittent gastrointestinal symptoms. In general, the national surveys sponsored by the U.S. Public Health Service have been shown to underestimate the prevalence of these conditions. In part, this is due to the fact that subjects are asked to report diagnoses rather than symptoms, and current coding schemes do not provide specific codes for each of the functional gastrointestinal disorders. Still, these studies have demonstrated the large number of physician visits and overall costs attributable to these disorders. A number of surveys of more limited populations have been done to assess the prevalence of these disorders. Rates have varied because of the definitions used and the degree to which organic diagnoses are excluded. These studies have been helpful in demonstrating the burden of illness in the community. Age and gender differences in the community have been much less marked than those identified in clinic-based studies, thus highlighting the importance of population-based research. Future studies need to focus on the incidence and natural history of these disorders. Studies of incidence cases can best evaluate the role of etiologic factors, whereas studies of prevalent cases are best for assessing the burden of disease in the community. Understanding the natural history of these disorders is important in determining the efficacy of future therapeutic interventions. The fact that these disorders represent 50% of visits to a gastroenterologist practice highlights the importance of these disorders and the potential contribution of gastrointestinal dysmotility in clinical practice.

Abstract
Patients with symptoms of GERD and dyspepsia are among the most common consulters in general practice and are different from their counterparts in the community who choose not to consult although they suffer from similar symptoms. They represent a heterogeneous group with considerable symptom overlap. They have a relatively poor quality of life and endoscopic findings can only explain symptoms in about half of these patients. Thus psychosocial factors which could contribute to their morbidity should be explored. While some studies have methodological shortcomings, main findings are that key psychological factors are anxiety, tension, neuroticism, somatization, fears of malignancy, negative assessment of health, depression, a poor social network and less effective coping strategies. Physical illness is likely to bring on psychological distress due to discomfort or threat of ill health. Cognizance of psychosocial factors will facilitate an understanding of the underlying problems and will improve diagnosis and selection of optimal treatment.

Abstract
Duodenal ulcer (DU) is a common medical disorder which frequently becomes chronic. The factors involved in the aetiology of DU are poorly understood. Evidence for the contribution of psychosocial factors to the onset of DU is reviewed in the context of evidence of organic factors, genetic and environmental, with special reference to new evidence of infectious agents in the aetiology of DU. Recent progress in understanding of biological forces of duodenal ulcer disease has lead to a substantially revised view of psychosomatic factors. Although these may be of significance, their relative contribution to aetiology is likely to be modest.

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
Patients with duodenal ulcer or functional dyspepsia do not differ on dyspeptic symptoms. The aim of the present study was to test the hypothesis that functional dyspepsia and duodenal ulcer are two different diagnostic entities by examining the discriminating power of several anamnestic, biological, and psychosocial variables. Ninety-four patients with duodenal ulcer and 86 patients with functional dyspepsia were included. Anamnestic data, global assessment, Helicobacter pylori status, blood group, Lewisa+ phenotype, and several measures of psychological distress and somatic complaints were registered. Compared to patients with functional dyspepsia, the duodenal ulcer patients were more often infected by Helicobacter pylori and had their stomach discomfort more often relieved by eating. Compared to patients with duodenal ulcer, patients with functional dyspepsia had higher scores of depression, trait anxiety, general psychopathology and different somatic complaints (called somatization). They were also less satisfied with the health care system, their disorder had a greater negative impact on their quality of life, and their global assessment of own health was poorer. Discriminant analysis including age, smoking, Helicobacter pylori status, global assessment, and somatic complaint classified 86.1% of the patients correctly (77.9% of the patients with functional dyspepsia and 93.6% of the patients with duodenal ulcer). It is concluded that duodenal ulcer and functional dyspepsia are two separate diagnostic entities. Patients with duodenal ulcer are older, smoke more often, and almost all are infected with Helicobacter pylori, while patients with functional dyspepsia are characterized by somatization and a negative assessment of their own health.

Abstract
BACKGROUND AND AIM In 40% of patients presenting to medical clinics with heartburn, no objective evidence of gastro-oesophageal reflux disease can be demonstrated. Little research has been performed regarding the psychological characteristics of these patients. The aim of this study was to assess the psycho-social profiles of patients presenting with heartburn in an attempt to discriminate between those with pathological reflux and those with functional disease. METHODS One hundred and thirty-eight patients presenting with heartburn underwent endoscopy and oesophageal pH monitoring. They were divided into those with oesophagitis or abnormal degrees of acid reflux into the oesophagus and those with normal endoscopy and normal pH profile. The psychological questionnaires used were the Hassles Scale, the State-Trait Anxiety Index, the Crown-Crisp Experiential Index and the Interview Schedule for Social Interaction. RESULTS Patients with functional heartburn did not report any increase in daily hassles nor did they have higher levels of anxiety, depression or other psychological characteristics than those with objective reflux disease. In terms of their available social support, the two groups were similar. CONCLUSION Differences in psychological characteristics and social support structures do not offer an explanation for the heartburn experienced by patients in the absence of objective evidence of reflux disease. Other explanations, including visceral hypersensitivity, should be sought 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
BACKGROUND Our aim was to contrast the psychosocial profiles of patients with gastro-oesophageal reflux disease whose symptoms correlate well with acid reflux against those whose symptoms do not. METHODS One hundred and one patients presenting with heartburn for the first time underwent oesophageal pH monitoring, and 82 (81%) experienced symptoms during the recording. On the basis of how well their symptoms correlated with acid reflux, patients were divided into symptom-positive and symptom-negative groups. These two groups were then compared on the basis of four questionnaires looking at different psychosocial factors. RESULTS Symptom-negative patients displayed significantly higher levels of trait anxiety (44.5 versus 38.7; p < 0.05) and hysteria (5.6 versus 4.1; p < 0.05). The adequacy of their social support structures was significantly lower (6.2 versus 7.3; p < 0.05). No difference in daily hassles or uplifts was found. CONCLUSION Significant psychosocial differences are noted in patients with poor symptom-reflux correlation. These differences may help explain the aetiology of such patients' symptoms.

Abstract
OBJECTIVES To investigate the direction of a possible relationship between peptic ulcer disease and personality disorders. DESIGN A cohort study of 50-year old patients, observed for 2 decades. SETTING Glostrup County, Denmark (population 100000). SUBJECTS A representative sample of 50-year old people born in 1914 (n = 673) were followed for 20 years. All 673 filled in the Minnesota Multiphasic Personality Inventory (MMPI) in 1964 and 513 were retested with MMPI in 1974. MAIN OUTCOME MEASURES Prevalence of peptic ulcer disease 1964, incidence of peptic ulcer disease 1964-84, MMPI scores. RESULTS The prevalence of peptic ulcer disease in 1964 was 7% and the average annual incidence in the period 1964-84 was 2.1 per 1000 persons. Those with incidental peptic ulcer in 1964-84 had normal MMPI scores in 1964, whilst those with peptic ulcer in 1964 had a slight but statistically significant increase in one neuroticism scale (HS) only. The group with prevalent ulcer disease in 1974 exhibited statistically significant increases in the three neuroticism scales (HS, D, HY) and in scale Pd and scale Pt at MMPI retesting. In addition they had statistically significantly higher scores in the three neuroticism scales compared with the other persons who still had normal scores in all scales. CONCLUSIONS Personality disorders in patients with peptic ulcer are consequences of the disease and not causal factors.

Abstract
OBJECTIVES To compare personality characteristics in duodenal ulcer patients and patients with ulcer-like dyspepsia from the primary health sector with duodenal ulcer patients from a hospital and to evaluate the relationship of the personality characteristics to the course of the diseases. DESIGN A prospective study using the Minnesota Multiphasic Personality Inventory (MMPI) with retesting of a subgroup of patients after a median observation period of 14 months. SETTING Departments of Medical and Surgical Gastroenterology, Hvidovre University Hospital, and the primary health sector in Roskilde County, Denmark. SUBJECTS Sixty hospital patients with duodenal ulceration and 17 patients with duodenal ulceration plus 25 patients with ulcer-like dyspepsia from the primary health sector. MAIN OUTCOME MEASURES MMPI scores. RESULTS The hospital patients differed from the two other groups of patients by having higher scores of depression and anxiety (P < 0.05). Twenty-eight of the patients were retested with MMPI. Contrary to the patients with persisting complaints, abnormal personality characteristics disappeared in patients without complaints (P < 0.05-0.001). CONCLUSIONS The results indicate that abnormal personality characteristics in patients with functional and organic upper dyspepsia are consequential rather than causal factors.

Abstract
BACKGROUND This study was designed to explore the relationships between serologic Helicobacter pylori positivity and demographic, behavioural, and symptomatologic factors in patients consulting for dyspeptic symptoms in general practice. METHODS H. pylori enzyme-linked immunosorbent assay results and checklist data were collected by general practitioners at three community health centers in southern Sweden from consecutive patients aged 18-65 years with upper abdominal pain or discomfort (dyspepsia). RESULTS Of the 130 available patients with dyspepsia, 127 agreed to participate, 45 (mean age, 41.2 years) being classified as H. pylori-positive and 82 (mean age, 33.5 years) as H. pylori-negative. Manual workers were diagnosed as H. pylori-positive significantly more often than were non-manual workers (p < 0.05). Of those patients examined earlier by gastroscopy or roentgenography, H. pylori-positives reported stomach or duodenal ulcer significantly more often than did H. pylori-negatives (p < 0.01). H. pylori-positives reported stomach/duodenal ulcer in their parents/siblings to a significantly greater extent than did H. pylori-negatives (45.2% versus 10.1%, p < 0.001). H. pylori-negatives reported stress-generated symptoms significantly more often than did H. pylori-positives (82.9% versus 61.5%, p < 0.01). Hierarchical regression analyses showed that, when age and sex were controlled for, the ability of each of these measures to predict the serologic results remained significant. CONCLUSIONS Higher levels of H. pylori antibodies in dyspeptic patients appear to be associated with a relatively low self-perception of stress, with manual work, with being older, and with the occurrence, both in the patients themselves and in their close relatives, of stomach/duodenal ulcer.

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
We provide current, normative data on the prevalence of impotence, and its physiological and psychosocial correlates in a general population using results from the Massachusetts Male Aging Study. The Massachusetts Male Aging Study was a community based, random sample observational survey of noninstitutionalized men 40 to 70 years old conducted from 1987 to 1989 in cities and towns near Boston, Massachusetts. Blood samples, physiological measures, socio-demographic variables, psychological indexes, and information on health status, medications, smoking and lifestyle were collected by trained interviewers in the subject's home. A self-administered sexual activity questionnaire was used to characterize erectile potency. The combined prevalence of minimal, moderate and complete impotence was 52%. The prevalence of complete impotence tripled from 5 to 15% between subject ages 40 and 70 years. Subject age was the variable most strongly associated with impotence. After adjustment for age, a higher probability of impotence was directly correlated with heart disease, hypertension, diabetes, associated medications, and indexes of anger and depression, and inversely correlated with serum dehydroepiandrosterone, high density lipoprotein cholesterol and an index of dominant personality. Cigarette smoking was associated with a greater probability of complete impotence in men with heart disease and hypertension. We conclude that impotence is a major health concern in light of the high prevalence, is strongly associated with age, has multiple determinants, including some risk factors for vascular disease, and may be due partly to modifiable para-aging phenomena.

Abstract
Immunoreactive-somatostatin (ir-SS) concentrations of the gastric mucosa and mood state in patients with functional dyspepsia were examined. The subjects were 12 patients with upper abdominal discomfort, nausea and/or vomiting (motility disorder group) and 14 patients complaining of upper abdominal pain (ulcer-like disorder group) for more than a month without any organic upper-gastrointestinal tract disease proven by endoscopy. These patients were compared with either an age- and sex-matched group of asymptomatic outpatients without any organic disease (control group: n = 26) or to a group of patients with peptic ulcer (n = 19). Somatostatin concentrations of the stomach were measured by radio-immunoassay, and the mood state of each subject was assessed by Manifest Anxiety Scale (MAS) and Self-rating Depression Scale test. Immunoreactive-somatostatin concentrations of the gastric mucosa were significantly higher in the ulcer-like disorder group than in the peptic ulcer, motility disorder or control group, and gastric juice levels were higher in the ulcer-like disorder group. The psychometric tests showed that the motility disorder group was more depressive than the ulcer-like disorder group, but there were no differences between the motility disorder, ulcer-like disorder and peptic ulcer group in MAS scores or environmental factors. These results indicate that there may be two different subgroups in functional dyspepsia influenced by both ir-SS concentration of the stomach and/or mood state.

Abstract
Functional dyspepsia (or 'non-ulcer') is usually defined as chronic or intermittent upper abdominal symptoms for which no organic cause can be found. Division of functional dyspepsia into subgroups such as reflux-like, ulcer-like, dysmotility-like and non-specific dyspepsia has been proposed, but lacks a scientific basis. Gastric acid hypersecretion, Helicobacter pylori-associated gastritis, gastric and small intestinal motor disorders, psychological and neurohormonal factors all might play a role in the pathogenesis. The heterogeneity of the underlying abnormalities makes it unlikely that one single treatment modality will ever be beneficial to all patients. In general practice, a therapeutic trial, with either a prokinetic or an acid secretion inhibiting drug, is usually carried out before diagnostic procedures are performed to exclude organic abnormalities. In the choice of the initial therapy, some guidance can be derived from the prominent symptoms. In a study in 30 H. pylori-negative patients with functional dyspepsia ranitidine (150 mg bid) significantly reduced the severity of heartburn. The effect was most pronounced in patients of the reflux-like subgroup.

Abstract
Ninety-three consecutive patients referred to a gastroenterology unit with unexplained dyspeptic symptoms were sent a postal questionnaire 6-12 months after endoscopy. It inquired into their current physical symptoms and subjective improvement since investigation, satisfaction with treatment, past history and current psychological well-being. A comparison group of 47 patients with peptic disease were similarly surveyed. Those with unexplained dyspepsia reported more current physical symptoms, more dissatisfaction with their treatment and less subjective improvement than those with peptic disease. The two groups were similar in terms of psychological distress but previous consultation for abdominal and other somatic complaints were more common in those with unexplained dyspepsia. The implications for management of dyspeptic patients are discussed.

Abstract
The authors reviewed the literature to assess the relationship between psychological factors and gastrointestinal conditions. The conditions that were found to be more relevant and worthy of future investigation were nonulcerative dyspepsia, inflammatory bowel disease (regional enteritis), and irritable bowel syndrome. The pertinent findings suggest that an important link exists between psychological factors and gastroenterological disorders, which supports the need for modification of the DSM-III-R's diagnostic category, "Psychological Factors Affecting Physical Condition." In concert with a subcommittee addressing other organ systems and psychological factors, the authors conclude that a diagnostic approach with greater utility would be useful for both researchers and clinicians. A conceptual framework as proposed in DSM-IV could also advance knowledge of psychological factors and their contribution or role in the etiology, perpetuation, and exacerbation of certain gastrointestinal conditions.
