Abstract
Irritable bowel syndrome (IBS) is a chronic gastrointestinal condition associated with altered bowel habits and recurrent abdominal pain, often triggered by food intake. Current treatments focus on improving stool pattern, but effective treatments for pain in IBS are still lacking due to our limited understanding of pathophysiological mechanisms. Visceral hypersensitivity (VHS), or abnormal visceral pain perception, underlies abdominal pain development in IBS, and mast cell activation has been shown to play an important role in the development of VHS. Our work recently revealed that abdominal pain in response to food intake is induced by the sensitization of colonic pain-sensing neurons by histamine produced by activated mast cells following a local IgE response to food. In this review, we summarize the current knowledge on abdominal pain and VHS pathophysiology in IBS, we outline the work leading to the discovery of the role of histamine in abdominal pain, and we introduce antihistamines as a novel treatment option to manage chronic abdominal pain in patients with IBS.

Abstract
BACKGROUND Real-world data on the outcome of routine treatment for disorders of gut-brain interaction (DGBI) in secondary care are lacking. METHOD A longitudinal study of consecutive adult patients with various DGBI attending this institution's gastroenterology clinic was conducted. Following 2 years of treatment, the proportion of patients with symptom improvement, details of clinical therapy, factors associated with and the impact of 'no symptom improvement' were determined. RESULTS A total of 289 patients (median age 68 years; 64.7% females; 28.4% irritable bowel syndrome (IBS), 20.1% functional dyspepsia (FD), 8.7% functional constipation (FC), 42.9% overlap syndrome) were recruited. After 2 years, 66.1% patients reported symptom improvement. Patients with overlap syndrome were less likely to have symptomatic improvement compared to those with a single DGBI (Overlap 55.6% vs IBS 74.4% vs FD 72.4% vs FC 76.0%, p = 0.014). Reassurance was associated with symptom improvement (p < 0.001). On multivariate analysis, overlap syndrome remained significantly associated with a poorer outcome (OR 2.27, 95% CI 1.22-4.25, p = 0.010), while providing reassurance was associated with a positive outcome (OR 0.30, 95% CI 0.16-0.56, p < 0.001). Only 25.6% and 14.9% of patients were referred for a low FODMAP diet and psychiatric intervention respectively. DGBI patients who had 'no improvement' were more likely to seek further GI consultations and had more work absenteeism. CONCLUSION Two-thirds of DGBI patients in secondary care showed symptom improvement. Patients who were reassured had better symptom improvement, while those with an overlap syndrome were associated with a poorer outcome, resulting in greater healthcare consultation and work absenteeism.

Gastric herpes simplex virus type 1 infection is associated with functional gastrointestinal disorders in the presence and absence of comorbid fibromyalgia: a pilot case-control study. Infection 2022; 50:1303-1311. [PMID: 35445970 PMCID: PMC9522778 DOI: 10.1007/s15010-022-01823-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Accepted: 03/31/2022] [Indexed: 12/12/2022]
Abstract
PURPOSE Animal studies have linked gastric herpesvirus infections to symptoms associated with functional gastrointestinal disorders (FGIDs). Herpesviruses have also been hypothesized to contribute to fibromyalgia (FM), a chronic pain syndrome frequently comorbid with FGIDs. The purpose of this study was to compare the prevalence of gastric herpesvirus infection in patients with FGIDs, with and without comorbid FM, to that of controls. METHODS For this pilot case-control study, we enrolled 30 patients who met both the Rome IV diagnostic criteria for one or more FGIDs and the American College of Rheumatology 2010 criteria for FM, 15 patients with one or more FGIDs without comorbid FM, and 15 control patients. Following endoscopic examination, gastric biopsies were analyzed for herpesvirus DNA and protein, Helicobacter pylori infection, and histological evidence of gastritis. Importantly, the viral nonstructural protein ICP8 was used as a marker to differentiate cell-associated actively replicating virus from latent infection and/or free virus passing through the GI tract. RESULTS Gastric herpes simplex virus type 1 (HSV-1) infection, as indicated by ICP8 presence, was significantly associated with FGIDs in the presence (OR 70.00, 95% CI 7.42-660.50; P < .001) and absence (OR 38.50, 95% CI 3.75-395.40; P < .001) of comorbid FM. Neither histological gastritis nor H. pylori infection were found to be associated with FGIDs or FM. CONCLUSIONS HSV-1 infection was identified in gastric mucosal biopsies from patients with diverse FGIDs, with and without comorbid FM. Larger, multi-center studies investigating the prevalence of this association are warranted.

Abstract
Functional dyspepsia is one of the most common functional gastrointestinal disorders with chronic bothersome epigastric pain or postprandial fullness without a definite organic cause. Despite its high clinical burden, the treatment modalities for modulating impaired motor dysfunction and visceral hypersensitivity have been unsatisfactory. Recently, studies demonstrating low-grade inflammation and dysbiosis of the duodenal mucosa as potential triggers of the disease have attracted attention. Observations, such as an increase in the proportion of oral commensal bacteria in the duodenal mucosa, such as Streptococcus species, highlight the importance of bacterial ecology in developing symptoms of functional dyspepsia. In the near future, anti-inflammatory drugs and probiotics that modulate the host-microbiome interaction are expected to emerge to treat functional dyspepsia.

Abstract
BACKGROUND/AIMS Overlap functional gastrointestinal disorder (FGID) is associated with more severe gastrointestinal symptoms and lower quality of life. The aim of this study is to evaluate clinical features of non-erosive reflux disease (NERD), functional dyspepsia, irritable bowel syndrome, their overlap in terms of sex and gender, and to assess the risk factors, including genetic polymorphisms. METHODS A total of 494 FGIDs and 239 controls were prospectively enrolled between 2004 and 2020. FGIDs were diagnosed based on the Rome III criteria and symptoms were evaluated using a questionnaire. Follow-up questionnaires were conducted to determine the change of symptoms during the 75.8-month mean observation period. Risk factors including genetic polymorphisms in neurotransmitter receptor (SLC6A4 5-HTTLPR, GNB3, ADRA2A, CCKAR, and TRPV1) and cytokine (TNFA and IL10) genes. RESULTS NERD was more prevalent in men, and functional dyspepsia in women. Overlap FGIDs (n = 239) were more prevalent than nonoverlap FGIDs (n = 255) in women (P = 0.019). Anxiety and depression scores were higher in the overlaps (P = 0.012 and P < 0.001, respectively). Symptoms were more frequent and severe in the overlap FGIDs than in the non-overlaps (P < 0.001). During followup, symptoms progressed more frequently in the overlap FGIDs, especially in patients with the L/S genotype of SLC6A4 5-HTTLPR and anxiety/depression. CONCLUSIONS Overlap FGID patients need attention given their association with anxiety/depression and more severe symptoms, especially in women. Genetic polymorphisms also may be associated with certain symptoms of overlap FGIDs.

Yeokwisan, a Standardized Herbal Formula, Enhances Gastric Emptying via Modulation of the Ghrelin Pathway in a Loperamide-induced Functional Dyspepsia Mouse Model. Front Pharmacol 2021; 12:753153. [PMID: 34630123 PMCID: PMC8493126 DOI: 10.3389/fphar.2021.753153] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Accepted: 09/09/2021] [Indexed: 12/03/2022] Open
Abstract
Background: Yeokwisan, a standardized herbal formula, has exhibited clinical benefit for patients suffering from refractory functional dyspepsia (FD) in Korea since 2016. However, data about the mechanism of action of this formula are yet not available. Aim of the study: To evaluate and explore the effects of Yeokwisan on gastric emptying, a major symptom of functional dyspepsia, and its underlying mechanisms of action using a mouse model. Materials and methods: BALB/C mice were pretreated with Yeokwisan (100, 200, and 400 mg/kg, po) or mosapride (3 mg/kg, po) for 5 days and then treated with loperamide (10 mg/kg, ip) after 20 h of fasting. A solution of 0.05% phenol red (500 μL) or diet of 5% charcoal (200 μL) was orally administered, followed by assessment of gastric emptying or intestinal transit. Plasma acyl-ghrelin (ELISA), C-kit (immunofluorescence and western blotting), nNOS (western blotting) and gastric contraction- and ghrelin-related gene/protein expression levels were examined in stomach and small intestine tissues. Results: Loperamide injection substantially delayed gastric emptying, while Yeokwisan pretreatment (especially 200 and 400 mg/kg Yeokwisan) significantly attenuated this peristaltic dysfunction, as evidenced by the quantity of phenol red retained in the stomach (p < 0.05 or 0.01) and stomach weight (p < 0.05 or 0.01). The levels of plasma acyl-ghrelin and expression of gastric ghrelin-related genes, such as growth hormone secretagogue receptor (GHSR), ghrelin-O-acyltransferase (GOAT), adrenergic receptor β1 (ADRB1) and somatostatin receptor (SSTR), were significantly normalized (p < 0.05 or 0.01) by Yeokwisan (400 mg/kg). Yeokwisan (400 mg/kg) significantly tempered the loperamide-induced alterations in the c-kit and nNOS levels (p < 0.01) as well as the expression of contraction- and ghrelin-related genes, such as 5-HT4 receptor (5-HT4R), anoctamin-1 (ANO1), ryanodine receptor 3 (RYR3) and smooth muscle myosin light chain kinase (smMLCK), in the stomach, but not in the small intestine. Conclusion: The present results showed the clinical relevance of Yeokwisan, in treating FD, especially in promoting gastric emptying but not small intestinal transit. The main mechanisms corresponding to these effects may involve the modulation of the ghrelin pathway and activation of interstitial cells of Cajal in stomach tissue.

Abstract
OBJECTIVES The prevalence of eating disorders is rising worldwide. The low body weight in anorexia nervosa as well as the increase in body mass index due to binge eating disorder are contributing to a strikingly high morbidity and mortality. In a similar pattern, the prevalence and burden of the disease of functional gastrointestinal disorders such as functional dyspepsia and irritable bowel syndrome is increasing. As gastrointestinal complaints are commonly reported by patients with eating disorders, the question arose whether there is a relationship between eating disorders and functional gastrointestinal disorders. METHODS To address the need to better understand the interplay between eating disorders and functional gastrointestinal disorders as well as factors that might influence this connection, the data bases Medline, Web of Science and Embase were systematically searched. RESULTS After removal of duplicates the search yielded 388 studies which were screened manually. As a result, 36 publications were selected for inclusion in this systematic review. CONCLUSION The occurrence of functional gastrointestinal disorders like irritable bowel syndrome and functional dyspepsia in patients with eating disorders is considerably high and often associated with psychological, hormonal and functional alterations. In the future, further research addressing the underlying mechanisms accounting for this relationship is required.

Abstract
BACKGROUND/PURPOSE There is scarcity of data on prevalence, overlap, and risk factors for functional gastrointestinal disorders (FGID) by Rome IV criteria. We evaluated these factors among medical, nursing, and humanities students. METHODS Rome IV Diagnostic Questionnaire (for all FGIDs), Rome III questionnaire (for irritable bowel syndrome [IBS], functional diarrhea [FDr], and functional constipation [FC]), and questionnaires assessing demography, physical activity, anxiety, and depression were used. RESULTS A total of 1309 college students were included (medical 425, nursing 390, humanities 494; mean age 20.5 ± 2.1 years; 36.5% males). Prevalence of Rome IV FGIDs was 26.9% (n = 352), significantly higher among females compared with males (32.3% vs. 17.6%; p < 0.001) and significantly higher among medical (34.4%) and nursing students (29.2%) compared with humanities students (18.6%) (p < 0.05). Most common FGIDs were functional dyspepsia (FD) (15.2%), IBS (6.2%), reflux hypersensitivity (3.5%), FDr (2.9%), FC (2.1%), and unspecified functional bowel disorder (2.1%). FGID overlap was present in 9.3%, most common being FD-IBS overlap (4.4%). With Rome III criteria, prevalence of IBS was higher (9.5%), while that of FDr (0.92%) and of FC (1.3%) were lower. On multivariate analysis, independent predictors for FGIDs were female gender, medical student, non-vegetarian diet, junk food, tea/coffee, poor physical activity, anxiety, and insomnia. CONCLUSION Rome IV FGIDs were present among one-fourth of college students with preponderance among females and medical students. FD, IBS, and reflux hypersensitivity were the most common FGIDs. Rome IV criteria led to a reduction in IBS prevalence and increase in FDr and FC prevalence. Dietary factors, physical activity, anxiety, and insomnia affected FGID prevalence.

Abstract
BACKGROUND Dyspepsia and heartburn are extremely common conditions, thus a search for safe and effective treatment alternatives is justified. OBJECTIVES To demonstrate the noninferiority of Gastricumeel (Ga6) in terms of effectiveness and safety to proton pump inhibitors (PPIs) in the treatment of patients with dyspepsia and/or heartburn. METHODS Prospective, comparative, observational cohort study. Patients with dyspepsia or heartburn were treated either with Ga6 or with PPIs as monotherapy during approximately 6 weeks. The intensity of eight symptoms was assessed as well as overall condition, treatment compliance and tolerability, and any adverse drug reactions. Adjustment for covariates was done via the calculation of propensity scores in logistic regression. RESULTS A total of 640 patients (447 Ga6, 193 PPIs) from 48 German general practices participated. More than half the patients had suspected acute gastritis and around 40% of patients had heartburn. Adjusted between-treatment difference scores of changes in the intensity of the eight assessed symptoms were within the bounds for noninferiority of Ga6 compared to PPIs. Effectiveness ratings were comparable; compliance and tolerability were rated better in the Ga6 group. CONCLUSION It is worth considering Ga6 as a safe and effective treatment option in the management of dyspepsia and heartburn.

Abstract
Objective: Quiescent ulcerative colitis (UC) patients often have irritable bowel syndrome (IBS)-like symptoms and we recently showed that the prevalence of IBS-like symptoms in UC patients in clinical remission was significantly higher as compared to healthy control subjects. However, the prevalence of functional dyspepsia (FD)-like symptoms in quiescent UC patients remains unknown. The purpose of this study was to evaluate the prevalence of FD-like symptoms and the overlap with IBS-like symptoms in such patients.Materials and Methods: We reanalyzed the records of UC patients in remission using the subject cohort from our previous study. Clinical remission was defined as a clinical activity index (CAI) value ≤4 for at least 6 months. Diagnoses of FD- and IBS-like symptoms were evaluated by questionnaire according to the Rome III criteria.Results: One hundred seventy-two UC patients in clinical remission and 330 healthy control subjects were analyzed. Of the 172 patients, 9 (5.2%) met the criteria of FD, which was comparable with the controls (22/330, 6.7%). The prevalence rate of FD-like symptoms in UC patients with IBS-like symptoms (7/46, 15.2%) was lower as compared to that of the control subjects (6/16, 37.5%). On the other hand, a high percentage of the UC patients with FD-like symptoms also had IBS-like symptoms (7/9, 77.8%).Conclusions: Although the prevalence of FD-like symptoms in quiescent UC patients with IBS-like symptoms was low, UC patients with FD-like symptoms frequently had IBS-like symptoms.

Abstract
OBJECTIVE The aim of this study was to investigate the predictor variables that could influence overlap syndrome in functional gastrointestinal disorders (FGID) among psychiatric patients. METHODS Data collected from 170 outpatients visiting the psychiatric clinic at a university hospital. FGIDs were screened according to the Rome III questionnaire-Korean version. Demographic factors were investigated, and psychosocial factors were evaluated using the Hospital Anxiety Depression Scale, Patient Health Questionnaire-15, Childhood Trauma Questionnaire-Korean and the Short form health survey. Chi-squared test, Student's t-test, one-way ANOVA, and Pearson's correlation test were used as statistical analysis methods. RESULTS There were no differences in the epidemiologic data between the two groups divided according to the FGID status. In those with FGID overlap syndrome, FD-NERD was most common (n=29), followed by IBS-NERD (n=20). Patients with overlap syndrome had the highest depressive, anxiety, and somatic symptoms. The overlap syndrome group had the lowest physical component summary and mental component summary. FGID symptom severity was significantly correlated with PCS and MCS in the overlap syndrome group. CONCLUSION Psychological factors are associated with the overlap syndrome of FGID. Acknowledging this common comorbidity may facilitate the recognition and treatment of patients with FGID.

Abstract
BACKGROUND Duodenal changes in functional dyspepsia (FD) might be related to the development of symptoms. However, relationships among low-grade inflammation, Helicobacter pylori infection, and protein expression by tight junctions (TJs) in the duodenum are unclear. We therefore aimed to determine whether duodenal inflammation and genes associated with TJ proteins are associated with FD. METHODS We evaluated inflammatory cell infiltration of the duodenum, H pylori infection, and genes associated with TJ proteins in duodenal biopsy specimens from 35 patients with FD according to the Rome III diagnostic questionnaire and from 31 asymptomatic controls without structural diseases. We immunohistochemically detected eosinophils and mast cells and counted them. The expression of claudins, occludin, and zonula occludens (ZO)-1 mRNA was evaluated using quantitative RT-PCR. Infection with H pylori was determined by measuring serum antibodies, rapid urease or urea breath tests, and endoscopic findings. RESULTS Sex, age, and H pyloriinfection rates did not differ between patients with FD and controls. The numbers of eosinophils and mast cells were significantly increased in patients with FD compared with controls and were significantly correlated. Inflammatory cell counts in the duodenum were not associated with H pylori infection status. Claudin-3 mRNA expression was increased in the patients with FD. CONCLUSIONS Subtle inflammation identified in the duodenum of patients with FD might be associated with the onset and persistence of dyspeptic symptoms.

Abstract
AIM Functional dyspepsia, originates from gastroduodenal region, is described as resistant and recurring dyspeptic symptoms with unknown etiology. Although there is some evidence in support of a relationship between functional dyspepsia and psychopathology, attachment patterns of functional dyspepsia patients have not been studied yet. In our study, we aimed to compare attachment patterns of functional dyspepsia patients with organic dyspepsia patients and healthy volunteers. METHOD 43 patients diagnosed with functional dyspepsia, 38 patients with organic dyspepsia and 42 healthy volunteers matched in terms of age, sex and education were included in the study. All participants were evaluated using a socio-demographic and clinical data questionnaire, the State and Trait Anxiety Inventory, the Experiences in Close Relationships Questionnaire and the Adult Attachment Scale. RESULTS There was no difference in sociodemographic features among the three groups. Functional dyspepsia group exhibited significantly higher Trait Anxiety scores compared to organic dyspepsia and control groups. Control group showed significantly higher secure attachment styles compared to functional dyspepsia and organic dyspepsia groups, there was no difference between groups in non-secure attachment styles according to triple attachment model. Dimensionally, functional dyspepsia group showed more avoidant attachment patterns than organic dyspepsia groups and organic dyspepsia group showed more avoidant attachment patterns than control group. CONCLUSION According to our findings, Functional dyspepsia patients are more anxious than organic dyspepsia patients and healthy volunteers. Non-secure attachment patterns were seen generally in all dyspeptic patients while avoidant attachment patterns are more prominent in functional dyspepsia patients.

Abstract
BACKGROUND/AIMS Sleep impairment is a common complaint among patients with irritable bowel syndrome (IBS) and functional dyspepsia (FD). This study aimed to evaluate the prevalence of sleep impairment in FD or IBS patients, and to determine whether IBS-FD overlap induced more sleep disturbance than FD or IBS alone. METHODS A population-based cohort in South Korea including 2251 subjects was asked about gastrointestinal symptoms including IBS and dyspepsia-related symptoms. In addition, sleep disturbance was measured using the Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale questionnaires. One-way ANOVA and logistic regression were used to assess differences among the 4 groups (healthy subjects, IBS alone, FD alone, and IBS-FD overlap). RESULTS Of 2251 subjects who were surveyed by questionnaire, 2031 responded (92.5% response rate) and were analyzed. The prevalence of IBS, FD, and IBS-FD overlap was 8.0% (95% confidence interval [CI], 6.8-9.2%), 4.8% (95% CI, 3.9-5.8%), and 1.8% (95% CI, 1.2-2.4%), respectively. FD alone, but not IBS alone, was significantly associated with a poorer sleep quality index (OR, 2.68; 95% CI, 1.43-5.01) and more daytime sleepiness (OR, 2.21; 95% CI, 1.14-4.30), compared to healthy subjects. IBS-FD overlap had the greatest likelihood of a poorer sleep quality index (OR, 3.88; 95% CI, 1.83-8.19), daytime sleepiness (OR, 2.47; 95% CI, 1.01-5.67), and insomnia (OR, 2.84; 95% CI, 1.39-5.82), compared to healthy subjects. CONCLUSION A correlation between functional gastrointestinal disorders and sleep disturbance was demonstrated, which was significantly pronounced in the context of IBS-FD overlap.

Abstract
BACKGROUND The primary purpose of this study was to compare Rome III and IV evaluation criteria for irritable bowel syndrome (IBS), functional dyspepsia (FD), and an overlap syndrome consisting of both IBS and FD by assessing the frequency of each diagnosis in a population of children with chronic abdominal pain. Frequencies of Rome IV FD subtypes of postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS) were determined and FD/IBS overlap symptom associations were also assessed. METHODS We conducted a cross-sectional retrospective chart review of 106 pediatric patients who had completed standardized medical histories as part of their evaluation for chronic abdominal pain. The patients ranged from eight to 17 years of age and reported having abdominal pain at least weekly for 8 weeks. Patients whose evaluation revealed gastrointestinal disease were excluded. The patients' diagnoses were determined by a single pediatric gastroenterologist utilizing the specific criteria for Rome III and IV, respectively. RESULTS Patients were significantly more likely to be diagnosed with FD (84.9% vs. 52.8%), IBS (69.8% vs. 34%), and FD/IBS overlap (58.5% vs. 17.9%) by Rome IV criteria, as compared to Rome III criteria. With regard to Rome IV FD subtypes, 81.1% fulfilled criteria for PDS, 11.1% fulfilled criteria for EPS, 6.7% fulfilled criteria for both, and 1.1% did not fulfill criteria for either. Finally, we found an increased frequency of diarrhea and pain with eating in the overlap group compared to the non-overlap group of Rome III, while only an increased frequency of diarrhea was found in the overlap group compared to the non-overlap group of Rome IV. CONCLUSIONS Our data demonstrate that utilizing Rome IV criteria, as compared to Rome III, results in an increase in the diagnosis of FD, a two-fold increase in the diagnosis of IBS, and a three-fold increase in the diagnosis of FD/IBS overlap. Rome IV criteria appears to result in greater heterogeneity within diagnostic categories. It is important to determine whether Rome IV diagnoses are predictive of treatment response, and if so, whether assessing symptom variability within a diagnosis will enhance the ability to select patients for a particular treatment.

Abstract
OBJECTIVES The Functional Dyspepsia Symptom Diary (FDSD) was developed to address the lack of symptom-focused, patient-reported outcome (PRO) measures designed for use in functional dyspepsia (FD) patients and meeting Food and Drug Administration recommendations for PRO instrument development. METHODS Concept elicitation interviews were conducted with FD participants to identify symptoms important and relevant to FD patients. A preliminary version of the FDSD was constructed, then completed by FD participants on an electronic device in cognitive interviews to evaluate the readability, comprehensibility, relevance, and comprehensiveness of the FDSD, and to preliminarily evaluate its measurement properties. RESULTS During concept elicitation interviews, 45 participants spontaneously reported 19 symptom concepts. Of those, seven symptoms were selected for assessment by the eight-item FDSD. Cognitive interviews with 57 participants confirmed that participants were able to comprehend and provide meaningful responses to the FDSD, and that the handheld electronic FDSD format was suitable for use in the target population. Scores of the FDSD were well-distributed among response options, item discrimination indices suggested that the FDSD items differentiate among patients with varying degrees of FD severity, and inter-item correlations suggested that no items of the FDSD were capturing redundant information. Internal consistency estimates (0.87) and construct-related validity estimates using known-groups methods were within acceptable ranges. CONCLUSIONS The FDSD is a content-valid PRO measure, with preliminary psychometric evidence providing support for the FDSD's items and total score. Further psychometric evaluations are recommended to more fully test the FDSD's score performance and other measurement properties in the target patient population.

Abstract
Functional dyspepsia is one of the most prevalent functional gastrointestinal disorders. Functional dyspepsia comprises three subtypes with presumed different pathophysiology and aetiology: postprandial distress syndrome (PDS), epigastric pain syndrome (EPS) and a subtype with overlapping PDS and EPS features. Functional dyspepsia symptoms can be caused by disturbed gastric motility (for example, inadequate fundic accommodation or delayed gastric emptying), gastric sensation (for example, sensations associated with hypersensitivity to gas and bloating) or gastric and duodenal inflammation. A genetic predisposition is probable but less evident than in other functional gastrointestinal disorders, such as irritable bowel syndrome (IBS). Psychiatric comorbidity and psychopathological state and trait characteristics could also play a part, although they are not specific to functional dyspepsia and are less pronounced than in IBS. Possible differential diagnoses include Helicobacter pylori infection and peptic ulceration. Pharmacological therapy is mostly based on the subtype of functional dyspepsia, such as prokinetic and fundus-relaxing drugs for PDS and acid-suppressive drugs for EPS, whereas centrally active neuromodulators and herbal drugs play a minor part. Psychotherapy is effective only in a small subset of patients, whereas quality of life can be severely affected in nearly all patients. Future therapies might include novel compounds that attempt to treat the underlying gastric and duodenal inflammation.

Abstract
BACKGROUND There have been no empirical validations of the Rome III or Rome IV criteria in children. The aim of the current study was to examine whether symptoms naturally occur in a pattern consistent with Rome III and/or Rome IV pediatric criteria for functional dyspepsia (FD) and irritable bowel syndrome (IBS). METHODS We conducted a retrospective cohort study of 250 children, ages 8-17 years, presenting to an abdominal pain clinic with pain of at least 8 weeks duration. We evaluated patterns of gastrointestinal (GI) and non-gastrointestinal (non-GI) symptoms which had been collected in a standardized fashion as part of routine clinical care. Confirmatory factor analyses were used to compare pre-existing models of symptoms clusters, namely Rome III and Rome IV criteria for IBS and FD in children and adolescents. Factor intercorrelations also were examined to determine whether IBS symptoms and non-GI somatic complaints correlate uniquely with FD symptom clusters. KEY RESULTS Both models demonstrated good fit with observed data [3-factor: χ2 (101, n=250)110.75, P<.05, TLI=.99, CFI=.99; 4-factor: χ2 (98, n=250)117.54, P<.05, TLI=.96, CFI=.97]. Fit indices and intercorrelations favored the more parsimonious 3-factor solution (3-factor: AIC=4654.91, BIC=4778.17; 4-factor: AIC=4757.16, BIC=4890.97) consistent with pediatric Rome III criteria that conceptualizes FD as a single diagnostic category. FD demonstrated significant overlap with IBS (.42), while non-GI-specific symptoms correlated significantly with FD (.64), but not IBS (.14) symptoms. CONCLUSIONS & INFERENCES GI symptoms in children presenting for initial evaluation of chronic functional abdominal pain occur in a pattern consistent with Rome III and IV pediatric criteria. Rome III offers a more parsimonious model. The presence of FD symptoms is strongly, and uniquely, associated with non-GI symptoms.

Abstract
Background/Aims In spite of increased concerns about the overlaps among the various functional gastrointestinal disorders (FGIDs), studies for the overlap between constipation and other common FGIDs are rare. Therefore, we investigated the patterns of overlaps between constipation and other common FGIDs. Methods This study was designed as a prospective nationwide multi-center questionnaire study using Rome III questionnaires for functional dyspepsia (FD), irritable bowel syndrome (IBS), and functional constipation (FC), as well as various questionnaires about patients' information, degree of symptoms, and quality of life. For the evaluation of gastroesophageal reflux disease (GERD), GERD-Q was used. Results From 19 centers, 759 patients with constipation were enrolled. The proportions of FC and IBS subtypes of constipation (IBS-C) were 59.4% and 40.6%, respectively. Among them, 492 (64.8%) showed no overlap. One hundred and thirty-six patients (17.9%) presented overlapping GERD, and 80 patients (10.5%) presented overlapping FD. Fifty one (6.7%) of patients were overlapped by both GERD and FD. Coincidental herniated nucleus pulposus (HNP) (P = 0.026) or pulmonary diseases (P = 0.034), reduced fiber intake (P = 0.013), and laxative use (P < 0.001) independently affected the rate of overlaps. These overlapping conditions negatively affected the constipation-associated quality of life, general quality of life, and degree of constipation. Conclusions The overlap of GERD or FD was common in patients with constipation. Coincidental HNP or pulmonary diseases, reduced fiber intake, and laxatives use were found to be independent associated factors for overlapping common FGIDs in Korean patients with constipation.

Abstract
This study investigated the psychological factors related to the overlap syndrome, i.e., multiple gastrointestinal conditions that are part of functional gastrointestinal disorders (FGIDs) in the same individual and potentially related to quality of life (QOL) among women aged 45-60 years (n = 627) in South Korea. The study was undertaken between July 2014 and March 2015. Depressive and anxiety symptoms were ascertained using the Center for Epidemiologic Studies Depression scale (CES-D) and the Beck Anxiety Inventory (BAI), respectively. Negative cognition and the cognitive triad were identified using the Automatic Thoughts Questionnaire-Negative (ATQ-N) and the Cognitive Triad Inventory (CTI), respectively. Resilience and QOL were assessed using the Connor-Davidson Resilience Scale (CD-RISC) and World Health Organization Quality of Life scale abbreviated version (WHOQOL-BREF). Women with the overlap syndrome had the highest CES-D (mean = 16.66 ± 11.79, p < .001), BAI (mean = 17.46 ± 12.67, p < .001), and ATQ-N scores (mean = 53.61 ± 20.88, p < .001), followed by women with gastrointestinal disorders but without the overlap syndrome and healthy controls. Healthy controls had the highest WHOQOL-BREF score (mean = 77.69 ± 12.53, p < .001). After stepwise selection, the final model explained 61.8 percent of the variance in QOL. Thus, depressive symptoms, anxiety, negative cognition, cognitive triad, and resilience were significantly related to QOL in women with the overlap syndrome.

Abstract
OBJECTIVE The aim of this study was to investigate the predictor variables that could influence overlap syndrome in functional gastrointestinal disorders (FGID) among firefighters in Korea. METHODS Data collected from 1217 firefighters in Korea were reviewed. FGID were diagnosed according to the Rome III diagnostic criteria. Psychological factors were measured by self-reported questionnaires. The scores for depression, anxiety, quality of life (QOL) and occupational job stress were analyzed. The correlation between psychological factors and QOL was analyzed and a stepwise multiple regression analysis was performed. RESULTS FGID were observed in 461 (37.9%) participants. In those with FGID, functional heartburn (FH) was most common (32.2%), followed by functional dyspepsia (12.2%). Patients with overlap syndrome had the highest depression, anxiety and occupational stress score than those having non-overlap syndrome and healthy controls, respectively (depression: F = 142.29, η(2) = 0.190; anxiety: F = 88.33, η(2) = 0.127; occupational stress: F = 43.68, η(2) = 0.067; all P < 0.001). Healthy controls had the highest QOL score (F = 73.39, P < 0.001, η(2) = 0.108). Pychological factors were significantly correlated with QOL in the overlap syndrome of FGID. After the stepwise selection, the final model explained 45.6% of predictable variance and contained four significant variables: depression, self-esteem, occupational stress and anxiety. CONCLUSIONS Psychological factors are associated with the overlap syndrome of FGID. Acknowledging this common comorbidity may facilitate the recognition and treatment of patients with FGID.

Abstract
At the present time, it is nearly impossible to treat pediatric functional gastrointestinal disorders associated with pain in an evidence based fashion. This is due to the overall lack of controlled studies and, even more importantly, the complexity of the contributors to disease phenotype which are not controlled or accounted for in most therapeutic trials. In this manuscript, we review the challenges of defining entry criteria, controlling for the large number of biopsychosocial factors which may effect outcomes, and understanding pharmacokinetic and pharmacodynamic factors when designing therapeutic trials for abdominal pain in children. We also review the current state of pediatric abdominal pain therapeutics and discuss trial design considerations as we move forward.

Abstract
AIM: To determine whether the decreased density of duodenal endocrine cells in irritable bowel syndrome (IBS) is associated with abnormalities in stem cell differentiation.
METHODS: The study sample comprised 203 patients with IBS (180 females and 23 males with a mean age of 36 years) and a control group of 86 healthy subjects without gastrointestinal complaints (77 females and 9 males with a mean age of 38 years). The patients included 80 with mostly diarrhoea (IBS-D), 47 with both diarrhoea and constipation (IBS-M), and 76 with mostly constipation (IBS-C). Both the patients and controls underwent gastroscopy and four biopsy samples were taken from the descending part of the duodenum, proximal to the papilla of Vater. The biopsy samples were sectioned and immunostained for Musashi 1 (Msi-1), neurogenin 3 (NEUROG3), secretin, cholecystokinin (CCK), gastric inhibitory peptide (GIP), somatostatin and serotonin. Immunostaining was performed with an ultraView Universal DAB Detection Kit (v1.02.0018, Venata Medical Systems, Basal, Switzerland) using the BenchMark Ultra immunohistochemistry/in situ hybridization staining module (Venata Medical Systems). Endocrine cell densities were quantified by computerized image analysis using the Olympus cellSens imaging program.
RESULTS: The densities of Msi-1 and NEUROG3 cells were significantly lower in IBS patients, regardless of the subtype, than in the controls (77 ± 17 vs 8 ± 2; P = 0.0001, and 351 ± 33 vs 103 ± 22; P = 0.00002, respectively). Furthermore, the densities of secretin, and CCK cells were significantly lower in patients with diarrhoea as the predominant IBS symptom (IBS-D) than in the controls (161 ± 11 vs 88 ± 8; P = 0.00007, and 325 ± 41 vs 118 ± 10; P = 0.00006, respectively), but not in patients with constipation as the predominant IBS symptom (IBS-C) or those with both diarrhoea and constipation (IBS-M). The GIP cell density was significantly reduced in both IBS-D (152 ± 12 vs 82 ± 7; P = 0.00003), and IBS-C (152 ± 12 vs 107 ± 8; P = 0.01), but not in IBS-M. The densities of somatostatin cells in the controls and the IBS-total, IBS-D, IBS-M and IBS-C patients were 81 ± 8, 28 ± 3, 20 ± 4, 37 ± 5 and 28 ± 4 cells/mm2 epithelium, respectively. The density of somatostatin cells was lower in IBS-total, IBS-D, IBS-M and IBS-C patients than in the controls (P = 0.00009, 0.00006, 0.009 and 0.00008, respectively). The density of serotonin cells did not differ between IBS patients and controls.
CONCLUSION: The reduction in duodenal endocrine cells in IBS patients found in this study is probably attributable to the reduction in cells expressing Msi-1 and NEUROG3.

Abstract
BACKGROUND Functional gastrointestinal disorders' (FGIDs) associations with body mass index (BMI) have not been thoroughly investigated in the general population. AIM To investigate the overlap between functional dyspepsia (FDy), irritable bowel syndrome (IBS), functional constipation (FC) and functional diarrhoea (FDh) and the relationship between BMI and those diagnoses in a large French adult population. METHODS Subjects participating in the Nutrinet-Santé cohort study completed a questionnaire based on Rome III criteria. Anthropometrics, socio-demographical and lifestyle data were collected via self-administered questionnaires. Associations between BMI and FGIDs were investigated with multivariate logistic regression. RESULTS A total of 35 447 subjects were included in the analysis. Among subjects with FGIDs, 10.4% presented more than one disorder. [FDy coexisted with IBS (23.6%) and FC (15.1%)]. Associations between BMI and FDy differed according to sex. In females, higher odds were observed for underweight and obesity subgroups (OR = 1.26 (95% CI: 0.99-1.59), OR = 1.35 (1.08-1.69), OR = 1.20 (0.81-1.77), OR = 1.47 (0.89-2.42) for underweight, class I, II and III obesity respectively compared with normal BMI), forming a U-shaped relationship confirmed with nonlinear model (P < 0.001). In females, FDh was associated with BMI [OR = 1.05 (1.03-1.07), P < 0.001]. In males, a negative association between BMI and IBS was observed [OR = 0.97 (0.94-0.99), P=0.04]. Other associations were not significant. CONCLUSIONS Our study showed an important overlap in FGIDs, supporting the contention of common pathophysiological mechanisms. Relationships between BMI and FGIDs appeared to be sex-dependent. Interaction by sex in the association between BMI and FGIDs should therefore be further explored.

Abstract
Patients with dyspepsia/functional dyspepsia (FD) show frequent overlapping of other gastrointestinal (GI) diseases, such as irri-table bowel syndrome, and non-GI diseases, in addition to internal subgroup overlapping. These overlap patients have more frequent or more severe symptoms, poorer health-related quality of life and higher somatization scores, and they are more like-ly to experience anxiety, depression or insomnia compared to non-overlap patients. The higher prevalence of overlap in patients with dyspepsia/FD is not by chance, indicating common pathogeneses, including visceral hypersensitivity, altered GI motility, in-fection, and stressful early life events. There are few clinical trials targeting overlap in patients with dyspepsia/FD, and no ther-apeutic strategy has been established. Further studies in this research area are needed. In this review, we describe the epidemi-ology, pathogenesis and treatment of overlap in patients with dyspepsia/FD.(J Neurogastroenterol Motil 2014;20:447-457).

Abstract
BACKGROUND AND AIM The association of various genetic polymorphisms with functional dyspepsia (FD) has been suggested, but the results were still controversial. The aim of the present study was to assess the association of GNB3 825C>T, SLC6A4 5-HTTLPR, ADRA2A-1291C>G, CCK-1R intron 779T>C, and TRPV1 945G>C polymorphisms with FD based on Rome III criteria in Korea. METHODS Study subjects were prospectively recruited from visitors to Seoul National University Bundang Hospital between 2009 and 2012. One hundred and twelve FD patients and 269 controls were enrolled. RESULTS In SLC6A4 5-HTTLPR polymorphism, the frequency of S/S genotype was significantly lower than that of L/L + L/S genotype in FD compared to controls (P < 0.05). After stratification according to Helicobacter pylori infection, the S/S genotype was significantly associated with H. pylori-positive epigastric pain syndrome (EPS) patients (adjusted odds ratio (OR) 0.46; 95% confidence interval (CI) 0.22-0.99; P = 0.048). In TRPV1 945G>C polymorphism, the frequency of C/C genotype was lower in FD compared to controls (P = 0.057). The C carrier and C/C genotype was significantly associated with postprandial distress syndrome (PDS) and EPS, respectively (adjusted OR 0.47 and 0.43; 95% CI 0.25-0.90 and 0.20-0.93; P = 0.021 and 0.033). After stratification, the significant associations remained in H. pylori-positive PDS and EPS patients (adjusted OR 0.37 and 0.28; 95% CI 0.16-0.88 and 0.09-0.85; P = 0.024 and 0.025). CONCLUSIONS The genetic polymorphism of SLC6A4 5-HTTLPR and TRPV1 945G>C could be one of the pathophysiological factors of FD, especially in the case of H. pylori-positive patients in Korea.

Abstract
BACKGROUND To date, no patient reported outcomes (PRO) instrument is available for evaluation of treatment efficacy in functional dyspepsia (FD)/postprandial distress syndrome (PDS). The aim of our study was to perform focus group interviews for the development of a new questionnaire for assessing symptom pattern and severity in PDS. METHODS Random ambulatory patients diagnosed with FD/PDS based on Rome III criteria and no predominant gastro-esophageal reflux disease (GERD) symptoms were invited to participate. Focus group sessions were organized where patients reported and discussed their symptoms, facilitated by an experienced physician. After reaching saturation of identified symptom items, questions for a pilot PRO instrument were drafted and evaluated in cognitive interviews for relevance, clarity, and consistency. KEY RESULTS Of 225 screened patients, 26 patients were diagnosed with PDS without overlapping GERD as single final diagnosis. Fifteen of these (87% female, 48 ± 3.2 years) participated in one of three focus groups. All (100%) confirmed experiencing symptoms that were triggered or aggravated by ingestion of a meal, corresponding to early satiation (100%), and postprandial fullness (100%). In addition reported gastroduodenal symptoms were nausea (40%, postprandial in all, interprandial in 20%), upper abdominal bloating (33%), excessive belching (27%), and vomiting (13%). Epigastric pain and burning were present in respectively 20% and 13%. Non-gastroduodenal symptoms that patients reported included heartburn (33%, but mostly sporadic), weight loss (93%, on average 5.0 ± 1.7 kg), and fatigue (67%). Questions evaluating these symptoms were validated in 15 cognitive interviews. CONCLUSIONS & INFERENCES This focus group study confirms symptoms corresponding to postprandial fullness and early satiation as the key items for developing a PRO for PDS.

Abstract
AIM: To investigate the relationship between interleukin-10 (IL-10) promoter gene polymorphisms and plasma levels and susceptibility to overlap syndrome of diarrhea irritable bowel syndrome (D-IBS) and functional dyspepsia (FD).
METHODS: Blood samples were collected from 164 patients and 200 healthy controls and genomic DNA was extracted. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to determine the genotypes in the -592A/C site, and amplification refractory mutation system polymerase chain reactions (ARMS-PCR) and DNA sequencing were performed to detect the polymorphism of the -1082G/A site. IL-10 plasma levels were determined by enzyme-linked immunosorbent assay (ELISA).
RESULTS: The -592A/C site in the IL-10 gene showed no significant differences in genotypes or allele frequency between the D-IBS-FD overlap syndrome group and control group, but the frequency of -592 CC genotype was significantly decreased in the D-IBS-FD overlap syndrome group. Compared with the CC genotype, the AA genotype and the AA+AC genotypes increased the risk of D-IBS-FD overlap syndrome 1.989 and 1.808 times, respectively. There were no significant differences in the distribution or the allele frequency of -1082 genotypes, the genotypes of the combination of -592 and -1082, and the distribution of the genotypes of different IL-10 levels between the D-IBS-FD overlap syndrome and healthy control groups. The average plasma IL-10 levels were significantly lower in patients with D-IBS-FD overlap syndrome than in healthy controls (14.60 pg/mL ± 7.14 pg/mL vs 22.86 pg/mL ± 10.62 pg/mL, P < 0.001). Among patients with D-IBS-FD overlap syndrome, the average plasma IL-10 levels in patients with -592 AA, -592 AC, -592 CC, and -592 AA+AC genotypes were 14.50 pg/mL ± 6.37 pg/mL, 14.85 pg/mL ± 7.75 pg/mL, 13.92 pg/mL ± 7.63 pg/mL, 14.68 pg/mL ± 7.10 pg/mL, respectively, which showed no significant differences. Plasma IL-10 levels showed no significant difference between the carriers of A allele and non-carriers.
CONCLUSION: The -592A site in IL-10 gene promoter and lower IL-10 plasma level may be associated with susceptibility to overlap syndrome of D-IBS and FD, but there is no association between them.

Abstract
To the best of our knowledge, stomach antral endocrine cells have not previously been investigated in patients with irritable bowel syndrome (IBS). Thus, in the present study, 76 patients with IBS were examined (designated as IBS-total). Diarrhoea was the predominant symptom in 26 of these patients (IBS-D), while in 21 patients, the predominant symptoms were both diarrhoea and constipation (IBS-M) and in 29 patients the predominant symptom was constipation (IBS-C). Forty-three healthy subjects were enrolled as the controls. Stomach antral biopsy samples obtained from all of the subjects were immunostained using the avidin-biotin-complex method for serotonin, gastrin, somatostatin and serotonin transporter (SERT). The immunopositive cell densities and immunoreactivity intensities were determined by computer-aided image analysis. The density of the serotonin-immunoreactive cells was significantly decreased in the IBS-M patients and increased in the IBS-C patients relative to the controls. The immunoreactivity intensity did not differ significantly between the controls and IBS-total. The density of the gastrin-immunoreactive cells was significantly greater in the IBS-D, IBS-M and IBS-C patients than in the controls. The immunoreactivity intensity of gastrin was significantly greater in the IBS-D patients than in the controls. The density of the somatostatin-immunoreactive cells cells was significantly lower in the IBS-total, IBS-D, IBS-M and IBS-C patients than in the controls. The immunoreactivity intensities of both somatostatin and SERT did not differ significantly between the controls and IBS-total. The increase in gastrin cell density and the decrease in somatostatin cell density in all IBS subtypes may cause high levels of gastric secretion, which may in turn contribute to the high incidence of dyspepsia and gastro-oesophageal reflux observed in patients with IBS.

Abstract
Functional gastrointestinal (GI) disorders are common in the general population. Based on the Rome III classification, these disorders are mutually exclusive disorders keeping the homogeneity of each functional GI disorder in research area. In contrast, many population and clinical studies have reported a considerably high rate of overlap between functional GI disorders. The overlap of functional GI disorders over other intestinal diseases might simply occur by chance due to a highly prevalent disorder. Moreover, functional GI disorders is considered a chronic stable disorder that may wax and wane for several years. However, a recent study about the natural history of functional GI disorders showed substantial transition among functional GI disorders over time. The natural history of functional GI disorders with overlapping other functional GI disorders are still in infancy and better understanding of these will be important in determining the efficacy of future therapeutic interventions.

Abstract
OBJECTIVES The objective of this systematic review and meta-analysis was to estimate the risk of developing functional dyspepsia (FD) following acute infectious gastroenteritis (IGE). METHODS Eligible studies were identified through PubMed and EMBASE searches. Data and quality indicators were extracted by two authors from nine studies examining the risk of FD following IGE in 5,755 exposed individuals. RESULTS Estimates of FD risk following IGE based on a random effects model yielded a pooled odds ratio (OR) of 2.18 (95% confidence interval (CI): 1.70-2.81). Subanalyses revealed differences in the odds of FD following self-reported IGE (OR: 2.83, 95% CI: 2.10-3.81) compared with documented IGE medical encounters (OR: 1.81, 95% CI: 1.26-2.58), and a decreasing FD risk with time from IGE (≤12 months: OR: 4.76, 95% CI: 2.47-9.20 and >12 months: OR: 1.97, 95% CI: 1.51-2.56). CONCLUSIONS Taken together, these data suggest that the risk of developing FD is significantly increased following IGE.

Abstract
BACKGROUND & AIMS Patients with diarrhea-predominant irritable bowel syndrome (IBS) have been found to have increased postprandial levels of serotonin (5-HT). Functional dyspepsia (FD) and IBS have been proposed to have common methods of pathogenesis, but little is known about the role of 5-HT in FD. METHODS We measured postprandial levels of 5-HT in 54 patients with FD (based on Rome III criteria) and 28 asymptomatic healthy individuals (controls). Patients with gastroesophageal reflux disease and IBS as their predominant symptom were excluded. After an overnight fast, the subjects drank a liquid meal (Ensure; 1.06 kcal/mL at 30 mL/min) and underwent a (13)C-octanoic acid breath test to measure gastric emptying times. Blood samples were collected at 0, 30, 60, 90, and 120 minutes after the liquid meal for the 5-HT assay. RESULTS Thirty-five patients with FD (65%) had postprandial distress syndrome, and 6 (11%) had a combination of postprandial distress syndrome and epigastric pain syndrome. There were no differences in rates of gastric emptying between patients with FD (103.6 ± 19.4 minutes) and controls (83.1 ± 4.0 minutes; P = .30). However, patients with FD had lower caloric intake (823.40 ± 44.1 kcal) than controls (1021 ± 68.2 kcal; P = .026). Patients with FD also had lower basal (P = .03) and postprandial plasma levels of serotonin at 30 minutes (P = .04), 60 minutes (P = .01), 90 minutes (P = .02), and 120 minutes (P = .002) than controls, as well as area under the curve values over the 120-minute time period (P = .005). Repeated-measures analysis of variance correlated 5-HT level with FD (P < .001). CONCLUSIONS In contrast to patients with diarrhea-predominant IBS, those with FD have decreased basal and postprandial plasma levels of 5-HT. These findings indicate that the pathogenic mechanism of FD differs from that of diarrhea-predominant IBS, and that strategies to alter 5-HT levels or activity might be developed to treat patients with FD.

Abstract
Despite being a large ethnic group within the South-East Asia, there is a paucity of reported literatures on dyspepsia in the Malay population. Recent population-based studies indicate that uninvestigated dyspepsia, based on the Rome II criteria, is reported in 12.8% and 11.6% of Malays in the urban and rural communities respectively. Organic causes of dyspepsia including upper gastrointestinal tract cancers, its precancerous lesions, and erosive diseases are uncommon which is largely due to an exceptionally low prevalence of Helicobacter pylori infection in this population. On the other hand, functional dyspepsia and irritable bowel syndrome are relatively common in the Malays than expected. Within a primary care setting, functional dyspepsia, based on the Rome III criteria, is reported in 11.9% of Malays, of which epigastric pain syndrome is found to be more common. Married Malay females are more likely to have functional dyspepsia and psychosocial alarm symptoms. Also based on the Rome III criteria, irritable bowel syndrome, commonly overlapped with functional dyspepsia, is reported in 10.9% of Malays within a community-based setting. Rather than psychosocial symptoms, red flags are most likely to be reported among the Malays with irritable bowel syndrome despite having a low yield for organic diseases. Based upon the above observations, "proton pump inhibitor test" is probably preferable than the "test and treat H. pylori" strategy in the initial management of dyspepsia among the Malays.

Abstract
Functional dyspepsia is a common disorder which imposes significant diagnostic and treatment challenges for patients and physicians. The most recent update of the diagnostic criteria subdivides functional dyspepsia into two subcategories based on the main symptom of epigastric pain or postmeal fullness. As we discuss in this review, several studies have shown significant overlap in symptoms and pathophysiology between functional dyspepsia, irritable bowel syndrome, and the spectrum of reflux disorders. This overlap in symptoms can be informative in helping us to understand the underlying pathophysiology, diagnostic approaches, and treatment strategies. The addition of diagnostic testing such as pH impedance manometry of the distal esophagus to the current common diagnostic tests might be helpful in distinguishing between functional dyspepsia and reflux disease. Importantly, various treatment modalities may be more effective than others if the main symptom is burning rather than pain or postmeal fullness rather than early satiation.

Abstract
Backgrounds The study aimed to survey for FD in a primary care setting in a population known to have an extremely low prevalence of Helicobacter pylori (H. pylori) infection, with the hypothesis that in such a population, dyspepsia should have been relatively less common. Methods The Rome III FD Diagnostic Questionnaire was translated into the Malay language and later tested for reliability. A prospective cross-sectional survey was then performed involving 160 Malay patients attending primary care clinic after informed consent. Patients positive for symptoms of FD were subjected to upper endoscopy and exclusion of H. pylori infection. Univariable and multivariable analyses were used to test for associated risk factors. Results The back-translated questionnaire was similar to the original English version and was reliable (Cronbach Alpha-coefficient 0.85). Of the 160 surveyed subjects, 19 of them (11.9%) had symptoms of FD. With exclusion of erosive diseases (3/160 or 1.9%) from endoscopy, 16 subjects or 10% had FD. None of the 19 subjects were positive for H. pylori infection. Epigastric pain syndrome was present in 11/16 (68.8%) and the rest, overlap with postprandial distress syndrome. With multivariable analysis, a married status (OR = 8.1; 95% CI 1.0-36.5) and positive psychosocial alarm symptoms (OR = 3.8; 95% CI 1.0-14.0) were associated with FD. Of those married subjects, females were more likely to have FD and psychosocial symptoms than men (6.3% vs. 1.9%), P = 0.04. Conclusions FD was more common than one had expected among Malays attending primary care clinic in an area with low prevalence of H. pylori.

Abstract
BACKGROUND Irritable bowel syndrome and other gastrointestinal (GI) and non-GI disorders such as functional dyspepsia, fibromyalgia, temporomandibular joint disorder, interstitial cystitis/painful bladder syndrome, and chronic fatigue syndrome are known as functional pain syndromes. They commonly coexist within the same individual. The pathophysiologic mechanisms of these disorders are not well understood, but it has been hypothesized that they share a common pathogenesis. PURPOSE The objective of this review is to discuss the proposed pathophysiologic mechanisms, which have been similarly studied in these conditions. These mechanisms include enhanced pain perception, altered regional brain activation, infectious etiologies, dysregulations in immune and neuroendocrine function, and genetic susceptibility. Studies suggest that these functional disorders are multifactorial, but factors which increase the vulnerability of developing these conditions are shared.

Abstract
BACKGROUND Functional dyspepsia (FD) is a heterogeneous disease, and categorized into postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). However, many FD patients have overlap of both PDS and EPS. The present study was designed to examine whether FD could be categorized based on the presence of concomitant gastrointestinal symptoms. METHODS A web survey comprised of the Gastrointestinal Symptom Rating Scale (GSRS), Rome III criteria of FD, and demographic information was sent to public participants who have no history of severe illness. Factor and cluster analyses were conducted to identify sub-categories of FD based on GSRS. KEY RESULTS A total of 8038 participants completed the survey. A total of 563 participants met the criteria for FD, whereas 6635 participants did not have dyspepsia symptoms. The remainder had either organic disease (377) or uninvestigated dyspepsia (463). The cluster analysis categorized participants as constipation predominant (cluster C), diarrhea predominant (cluster D), or having neither diarrhea nor constipation (cluster nCnD). Cluster C and D were significantly associated with the presence of FD [odds ratio (OR) 2.57, 95% confidence interval (CI) 2.06-3.21; OR 2.80; 95% CI 2.27-3.45, respectively]. In FD, especially in PDS cases, the scores of upper gastrointestinal symptoms were higher in cluster C or D than in cluster nCnD. CONCLUSIONS & INFERENCES The severity of dyspepsia symptoms is associated with the presence of bowel symptoms especially in PDS. This novel categorization of FD based on concomitant constipation or diarrhea may improve classification of patients.
