Al-Beltagi M, Saeed NK, Bediwy AS, Elbeltagi R. Fecal calprotectin in pediatric gastrointestinal diseases: Pros and cons. World J Clin Pediatr 2024; 13:93341. [DOI: 10.5409/wjcp.v13.i2.93341] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Revised: 04/28/2024] [Accepted: 05/14/2024] [Indexed: 06/07/2024] Open
Abstract
BACKGROUND Fecal calprotectin is a valuable biomarker for assessing intestinal inflammation in pediatric gastrointestinal diseases. However, its role, pros, and cons in various conditions must be comprehensively elucidated.
AIM To explore the role of fecal calprotectin in pediatric gastrointestinal diseases, including its advantages and limitations.
METHODS A comprehensive search was conducted on PubMed, PubMed Central, Google Scholar, and other scientific research engines until February 24, 2024. The review included 88 research articles, 56 review articles, six meta-analyses, two systematic reviews, two consensus papers, and two letters to the editors.
RESULTS Fecal calprotectin is a non-invasive marker for detecting intestinal inflammation and monitoring disease activity in pediatric conditions such as functional gastrointestinal disorders, inflammatory bowel disease, coeliac disease, coronavirus disease 2019-induced gastrointestinal disorders, gastroenteritis, and cystic fibrosis-associated intestinal pathology. However, its lack of specificity and susceptibility to various confounding factors pose challenges in interpretation. Despite these limitations, fecal calprotectin offers significant advantages in diagnosing, monitoring, and managing pediatric gastrointestinal diseases.
CONCLUSION Fecal calprotectin holds promise as a valuable tool in pediatric gastroenterology, offering insights into disease activity, treatment response, and prognosis. Standardized protocols and guidelines are needed to optimize its clinical utility and mitigate interpretation challenges. Further research is warranted to address the identified limitations and enhance our understanding of fecal calprotectin in pediatric gastrointestinal diseases.

Front Microbiol 2024; 15:1343564. [PMID: 38855762 PMCID: PMC11157101 DOI: 10.3389/fmicb.2024.1343564] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Accepted: 04/29/2024] [Indexed: 06/11/2024] Open
Abstract
Background The main functional gastrointestinal disorders (FGIDs) include functional dyspepsia (FD) and irritable bowel syndrome (IBS), which often present overlapping symptoms with gastroesophageal reflux disease (GERD), posing a challenge for clinical diagnosis and treatment. The gut microbiota is closely associated with FGIDs and GERD, although the causal relationship has not been fully elucidated. Therefore, we aimed to investigate the potential causal relationship using bidirectional two-sample Mendelian randomization (MR) analysis. Materials and methods The genetic data of the 211 gut microbiota were obtained from the MiBioGen consortium (N = 14,306, from phylum to genus level) and species level of gut microbiota were acquired from the Dutch Microbiome Project (N = 7,738). For FD and IBS, we utilized the FinnGen consortium, whereas, for GERD data analysis, we obtained the IEU OpenGWAS project. The inverse-variance weighted (IVW) method was used as the primary method to calculate causal effect values. Sensitivity analyses were also performed to confirm the robustness of the primary findings of the MR analyses. Moreover, a reverse MR analysis was conducted to assess the likelihood of reverse causality. Results Combining the results of the preliminary and sensitivity analyses, we identified that 8 gut microbial taxa were associated with FD. Genus Lachnospiraceae NK4A136 group (p = 3.63 × 10-3) and genus Terrisporobacter (p = 1.13 × 10-3) were strongly associated with FD. At the same time, we found that 8 gut microbial taxa were associated with IBS. Family Prevotellaceae (p = 2.44 × 10-3) and species Clostridium leptum (p = 7.68 × 10-3) display a robust correlation with IBS. In addition, 5 gut microbial taxa were associated with GERD using the IVW approach. In the reverse MR analysis, 2 gut microbial taxa were found to be associated with FD, 5 gut microbial taxa were found to be associated with IBS, and 21 gut microbial taxa were found to be associated with GERD. Conclusion The study reveals the potential causal effects of specific microbial taxa on FD, IBS, and GERD and may offer novel insights into the diagnosis and treatment of these conditions.

Abstract
BACKGROUND According to the theory of traditional Chinese medicine (TCM), all types of body constitutions, except for the Gentleness (ie, the control group in our study), have disease susceptibility and affect the disease development process. This study attempted to investigate the relationship between TCM body constitutions and irritable bowel syndrome (IBS). METHODS This cross-sectional study was based on Taiwan Biobank (TWB) and collected clinical data from 13 941 subjects aged 30 to 70. The results of the study showed that subjects with Yang-deficiency (N = 3161 subjects, odds ratio [OR] = 2.654, 95% CI = 1.740-3.910), Ying-deficiency (N = 3331 subjects, OR = 1.096, 95% CI = 0.627-1.782) or Stasis (N = 2335 subjects, OR = 1.680, 95% CI = 0.654-3.520) were more likely to have IBS. RESULTS If the subjects with two or more TCM body constitutions: Yang-deficiency + Ying-deficiency (OR = 3.948, 95% CI = 2.742-5.560), Yang-deficiency + Stasis (OR = 2.312, 95% CI = 1.170-4.112), Ying-deficiency + Stasis (OR = 1.851, 95% CI = 0.828-3.567), or Yang-deficiency + Ying-deficiency + Stasis (OR = 3.826, 95% CI = 2.954-4.932) were also prone to IBS. CONCLUSION These results confirmed the high correlation between TCM body constitutions and IBS. Because the current treatment for IBS is not entirely satisfactory, integrated traditional Chinese and Western medicine might provide patients with an alternative treatment option to alleviate IBS.

Abstract
BACKGROUND Functional gastrointestinal disorders (FGIDs), also known as disorders of gut-brain interaction, occur not only in the elderly but also in young adults. This study aimed to evaluate the association between mental health conditions and FGIDs among Vietnamese new-entry medical students. METHODS This cross-sectional study was conducted in February 2022 among new-entry medical students in Ho Chi Minh City, Vietnam. A printed questionnaire was distributed to all students on the day of freshmen health screening. Their urine samples were collected to screen for Helicobacter pylori infection using rapid urinary test. FGIDs were diagnosed using ROME IV criteria. Gastroesophageal reflux disease (GERD) was defined as the presence of typical reflux symptoms at least twice a week. Mental health conditions, including generalized anxiety disorder (GAD) and major depressive disorder (MDD), were identified using Generalized Anxiety Disorder Assessment-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) scales, respectively. RESULTS Among 400 new-entry medical students who participated in the study, the overall prevalence of FGIDs was 10.3% (functional dyspepsia 6.5%, irritable bowel disease 5.5%). The overlap syndrome (OS) of GERD-FGIDs or different FGIDs was present in 3.0% of participants. The prevalences of GAD and MDD were 6.8% and 10.2%, respectively. The urinary test was positive in 180 (45.0%) participants. In the multivariable logistic regression analysis, MDD was significantly associated with not only the risk of FGIDs (OR = 5.599, 95%CI: 2.173-14.430, p<0.001) but also the risk of OS (OR = 10.076, 95CI%: 2.243-45.266, p = 0.003). CONCLUSIONS MDD is associated with FGIDs and OS among new-entry medical students.

Abstract
Background and Aim Gastrointestinal reflux disease (GERD) and irritable bowel syndrome (IBS) are among the most common gastrointestinal disorders in which the overlap of these diseases and their syndromes has been frequently reported. In this study, we aimed to evaluate GERD incidence among IBS patients and the related risk factors. Methods Male patients aged 18-60 years with an impression of IBS and referred to the gastrointestinal clinic from March 2019 to 2020 in Shiraz, Iran, were included in this study. Results Among the 163 enrolled patients with an average age of 31.53 ± 9.38 years, 64 (39.3%) were diagnosed with GERD. Based on statistical analysis, there was a significant association between GERD and the IBS patients' age (P = 0.006), smoking (P = 0.011), and alcohol consumption (P = 0.043). Also, GERD among IBS patients was significantly associated with the type of IBS (P < 0.001), with IBS-D having the lowest incidence (19.4%) and IBS-M the highest incidence of GERD (66.7%). Based on multivariate analysis, smoking had a reverse and significant correlation with lower incidence of GERD (OR = -1.364; P = 0.002). Conclusion Our results demonstrate that among male IBS patients, younger age, smoking, and alcohol consumption were among the risk factors for GERD. These findings may provide further insight into the best approach to treating these diseases.

Abstract
Gastroesophageal reflux disease (GERD) and functional gastrointestinal disorders (FGIDs), including irritable bowel syndrome and functional dyspepsia, are common afflictions within the general population. Both conditions have a considerable impact on the daily health related quality of life (HRQoL) of affected individuals. Risk factors surrounding any impaired HRQoL in patients with GERD involve those of younger age, obesity, an increase in reflux symptom frequency, and overlapping FGIDs. The risk factors for subjects experiencing an overlap in FGIDs and GERD involve those who are female, younger age, cigarette smoking, non-erosive reflux disease, more GERD symptoms, and psychological performances including anxiety, somatization, and more frequent healthcareseeking behavior. The overlap of GERD and FGIDs is associated with a worsening of both physical and mental health, an increase in bothersome symptoms, impaired functional capacity, and a higher likelihood of consulting a physician. Acid secretion suppressors could offer therapeutic efficacy to some patients experiencing overlapping GERD and FGIDs.

Abstract
BACKGROUND Indian population-based studies on the prevalence and risk factors for gastroesophageal reflux disease (GERD) are scanty, and a meta-analysis and a meta-regression of prevalence and risk factors based on the existing data have not yet been reported. METHODS A systematic review of all the available publications from India reporting data regarding prevalence and risk factors of GERD was performed. Heterogeneity was assessed using I2 statistics. The meta-analysis was undertaken to measure the average proportion reported in the existing studies, and meta-regression models were used to explore the risk factors for it. RESULTS The nine studies included 20,614 subjects; the prevalence of GERD ranged from 5% to 28.5%. The summary effect size (weighted average proportion) estimated by meta-analytic model was 0.1415 (95% confidence interval [CI] 0.099 to 0.197). The results for the test of heterogeneity that included tau2 (0.37, 95% CI 0.21 to 1.80), I2 (98.9%, 95% CI 98.01 to 99.77), and the Q-statistic (707.670; p < 0.0001) suggested high heterogeneity in the effect sizes. The pooled proportion of GERD (random-effects model) was 15.573 (95% CI 11.046 to 20.714). In the meta-regression model, sample size (p = 0.005) explained about 50% of the heterogeneity. CONCLUSION The pooled prevalence of GERD in the Indian population is 15.6 (95% CI 11.046 to 20.714). The risk factors were age, body mass index (BMI), non-vegetarian diet, tea/coffee intake, tobacco, and alcohol consumption. However, there was significant heterogeneity in the studies.

Abstract
Gastroesophageal reflux disease (GERD) is a common disorder, and empirical proton pump inhibitor (PPI) treatment is often the first step of management; however, up to 40% of patients remain symptomatic despite PPI treatment. Refractory reflux refers to continued symptoms despite an adequate trial of PPI, and management remains challenging. The differential diagnosis is important; other oesophageal (e.g. eosinophilic oesophagitis) and gastroduodenal disorders (e.g. functional dyspepsia) should be ruled out, as this changes management. A combination of clinical assessment, endoscopic evaluation and in selected cases oesophageal function testing can help characterize patients with refractory reflux symptoms into oesophageal phenotypes so appropriate therapy can be more optimally targeted. Medical options then may include adding a H2 receptor antagonist, alginates, baclofen or antidepressant therapy, and there is emerging evidence for bile acid sequestrants and diaphragmatic breathing. The demonstration of a temporal association of symptoms with reflux events on pH-impedance testing (reflux hypersensitivity) serves to focus the management on modulating oesophageal perception and reducing the reflux burden, or identifies those with no obvious pathophysiologic abnormalities (functional heartburn). Anti-reflux surgery based on randomized controlled trial evidence has a role in reflux hypersensitivity or continued pathological acid reflux despite PPI in carefully considered, fully worked up cases that have failed medical therapy; approximately two of three cases will respond but there is a small risk of complications. In patients with persistent volume reflux despite medical therapy, given the lack of alternatives, anti-reflux surgery is a consideration. Promising newer approaches include endoscopic techniques. This review aims to summarize current diagnostic approaches and critically evaluates the evidence for the efficacy of available treatments.

Abstract
BACKGROUND AND AIM As there is a scarcity of data on overall prevalence, risk factors, and health-care utilization of esophageal symptoms using the Rome criteria in the rural population in Asia, we undertook a study with the aims to evaluate: (i) the prevalence of heartburn, chest pain, globus, and dysphagia of presumed esophageal origin; (ii) the prevalence of functional esophageal disorders by Rome III criteria; (iii) the risk factors for esophageal symptoms; and (iv) the health-care utilization. METHODS This door-to-door survey was conducted in three villages (Charcharia, Churain of Dhaka district, and Kharrah of Munshiganj district of Bangladesh) among the adult population (≥18 years) using the translated and validated Enhanced Asian Rome III questionnaire. RESULTS Of 3559 individuals, 3351 (94.15%) responded (mean age 40.41 ± 16.04 years, female, 1924 [57.4%]). Heartburn was the most common symptom, 863 (25.8%), followed by chest pain, 367 (11%); globus, 285 (8.5%); and dysphagia, 146 (4.4%). At least one symptom was present in 1108 (33.1%) respondents. Based on Rome III criteria, 428 (12.8%), 41 (1.2%), 49 (1.5%), 26 (0.8%), and 524 (15.6%) had heartburn, chest pain, globus, dysphagia, and at least one functional esophageal disorder, respectively. Female gender, lower family income, presence of functional dyspepsia-irritable bowel syndrome (FD-IBS) overlap, FD only, and psychological distress were found to be risk factors for esophageal symptoms on multivariate analysis. Among the subjects with any esophageal disorders, 156 (14.1%) consulted any health-care provider, and 517 (46.6%) took antisecretory medications. CONCLUSION Esophageal symptoms are common in the rural community of Bangladesh and are associated with substantial health resource utilization.

Abstract
The human gastrointestinal tract harbors most of the microbial cells inhabiting the body, collectively known as the microbiota. These microbes have several implications for the maintenance of structural integrity of the gastrointestinal mucosal barrier, immunomodulation, metabolism of nutrients, and protection against pathogens. Dysfunctions in these mechanisms are linked to a range of conditions in the gastrointestinal tract, including functional gastrointestinal disorders, ranging from irritable bowel syndrome, to functional constipation and functional diarrhea. Irritable bowel syndrome is characterized by chronic abdominal pain with changes in bowel habit in the absence of morphological changes. Despite the high prevalence of irritable bowel syndrome in the global population, the mechanisms responsible for this condition are poorly understood. Although alterations in the gastrointestinal microbiota, low-grade inflammation and immune activation have been implicated in the pathophysiology of functional gastrointestinal disorders, there is inconsistency between studies and a lack of consensus on what the exact role of the microbiota is, and how changes to it relate to these conditions. The complex interplay between host factors, such as microbial dysbiosis, immune activation, impaired epithelial barrier function and motility, and environmental factors, including diet, will be considered in this narrative review of the pathophysiology of functional gastrointestinal disorders.

Oka P, Parr H, Barberio B, Black CJ, Savarino EV, Ford AC. Global prevalence of irritable bowel syndrome according to Rome III or IV criteria: a systematic review and meta-analysis. Lancet Gastroenterol Hepatol 2020; 5:908-917. [PMID: 32702295 DOI: 10.1016/s2468-1253(20)30217-x] [Citation(s) in RCA: 296] [Impact Index Per Article: 74.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2020] [Revised: 06/04/2020] [Accepted: 06/04/2020] [Indexed: 01/30/2023]
Abstract
BACKGROUND Irritable bowel syndrome (IBS) is one of the most common functional bowel disorders, but community prevalence appears to vary widely between different countries. This variation might be due to the fact that previous cross-sectional surveys have neither applied uniform diagnostic criteria nor used identical methodology, rather than being due to true global variability. We aimed to determine the global prevalence of IBS. METHODS We did a systematic review and meta-analysis of data from all population-based studies using relatively uniform methodology and using only the most recent iterations of the Rome criteria (Rome III and IV). We searched MEDLINE, Embase, and Embase Classic (from Jan 1, 2006, to April 30, 2020) to identify cross-sectional surveys reporting the prevalence of IBS in adults (≥90% of participants aged ≥18 years) according to the Rome III or Rome IV criteria. We also hand-searched a selection of conference proceedings for relevant abstracts published between 2006 and 2019. We extracted prevalence data for all studies, according to the criteria used to define the presence of IBS. We did a meta-analysis to estimate pooled prevalence rates, according to study location and certain other characteristics (eg, sex and IBS subtype). FINDINGS We identified 4143 citations, of which 184 studies appeared relevant. 57 of these studies were eligible, and represented 92 separate adult populations, comprising 423 362 participants. The pooled prevalence of IBS in 53 studies that used the Rome III criteria, from 38 countries and comprising 395 385 participants, was 9·2% (95% CI 7·6-10·8; I2=99·7%). By contrast, pooled IBS prevalence among six studies that used the Rome IV criteria, from 34 countries and comprising 82 476 individuals, was 3·8% (95% CI 3·1-4·5; I2=96·6%). IBS with mixed bowel habit (IBS-M) was the most common subtype with the Rome III criteria, reported by 33·8% (95% CI 27·8-40·0; I2=98·1%) of people fulfilling criteria for IBS (ie, 3·7% [2·6-4·9] of all included participants had IBS-M), but IBS with diarrhoea (IBS-D) was the most common subtype with the Rome IV criteria (reported by 31·5% [95% CI 23·2-40·5; I2=98·1% 61·6%] of people with IBS, corresponding to 1·4% [0·9-1·9] of all included participants having IBS-D). The prevalence of IBS was higher in women than in men (12·0% [95% CI 9·3-15·0] vs 8·6% [6·3-11·2]; odds ratio 1·46 [95% CI 1·33-1·59]). Prevalence varied substantially between individual countries, and this variability persisted even when the same diagnostic criteria were applied and identical methodology was used in studies. INTERPRETATION Even when uniform symptom-based criteria are applied, based on identical methodology, to define the presence of IBS, prevalence varies substantially between countries. Prevalence was substantially lower with the Rome IV criteria, suggesting that these more restrictive criteria might be less suitable than Rome III for population-based epidemiological surveys. FUNDING None.

Abstract
BACKGROUND Temporomandibular disorders (TMDs) are a family of pain-related disorders associated with impaired function in the jaw, temporomandibular joint and muscles of mastication. Our objectives were to evaluate the association between chronic TMD and gastresophageal reflux disease (GERD) and to determine whether mental disorders or undermined sleep mediates this association. METHODS We conducted a case-control study involving 1522 consecutive adult patients with chronic TMD and 1522 matched controls from 2 hospitals in China. All participants were aged between 18 and 70 years and were recruited from July 2017 to April 2018 Chronic TMD was diagnosed by trained dentists using the criteria in the Orofacial Pain Prospective Evaluation and Risk Assessment Study. Trained gastroenterologists made blinded diagnoses of GERD according to the Montreal definition and classification (at least 2 d of mild symptoms, or 1 d of moderate or severe symptoms per week). We used validated questionnaires to evaluate psychological status and sleep quality. RESULTS Of the study participants, we identified 132 patients and 61 controls with GERD. Using conditional logistic regression analysis, we identified GERD as a risk factor for TMD (odds ratio 2.74, 95% confidence interval 1.88 to 3.98). Mediation analyses identified that somatization, anxiety and undermined sleep moderately mediated the relation between TMD and GERD. INTERPRETATION Our study suggests that symptomatic GERD is associated with chronic, painful TMD, and somatization, anxiety and undermined sleep mediate this association to a certain extent. Due consideration should be given to the evaluation and management of gastrointestinal symptoms and mental disorders in the combined therapy for painful TMD.

Abstract
Although gastro-oesophageal reflux disease (GORD) is a common medical complaint, there is currently no consensus on the global prevalence of GORD. The aim of this study was to conduct a systematic review and meta-analysis on GORD prevalence and risk factors at a global level. MEDLINE, EMBASE, CINAHL, Scopus, Cochrane library, and Google Scholar were systematically searched, without language restrictions, for studies on the prevalence and risk factors of GORD. Data were pooled using a random effects model (95% confidence interval), and the odds ratio and relative risk for each risk factor were calculated. Out of 34,355 search results, 96 records reporting the results from 102 studies fulfilled the inclusion criteria, representing 37 countries and all regions of the UN geoscheme. The global pooled prevalence of GORD was 13.98% and varied greatly according to region (12.88% in Latin America and the Caribbean to 19.55% in North America) and country (4.16% in China to 22.40% in Turkey). Using the United Nations 2017 Revision of World Population Prospects, the estimated number of individuals suffering from GORD globally is 1.03 billion. Multiple risk factors associated with a significant increase in the risk of GORD were also identified. This systematic review and meta-analysis revealed that although a substantial proportion (13.98%) of the global population suffers from GORD, there are significant variations between regions and countries. Risk factors for GORD were also identified which may allow clinicians to recognise individuals most at risk.

Abstract
Several studies have implied a role of brain-derived neurotrophic factor (BDNF) in abdominal pain modulation in irritable bowel syndrome (IBS). The aim of this study was to establish BDNF protein expression in human colonic biopsies and to show variation in IBS compared to controls. BDNF protein and mRNA levels were correlated with IBS symptom severity based on the IBS-symptom severity score (IBS-SSS). Biopsies from the descending colon and IBS-SSS were obtained from 10 controls and 20 IBS patients. Total protein of biopsies was extracted and assessed by ELISA and Western Blot. Total mRNA was extracted and gene expression measured by nCounter analysis. In IBS patients, symptom severity scores ranged from 124 to 486 (mean ± sem: 314.2 ± 21.2, >300 represents severe IBS) while controls ranged from 0 to 72 (mean ± sem: 27.7 ± 9.0, <75 represents healthy subjects, p < 0.001). IBS patients reported significantly more food malabsorption, former abdominal surgery and psychiatric comorbidities. BDNF protein was present in all samples and did not differ between IBS and controls or sex. Subgroup analysis showed that female IBS patients expressed significantly more BDNF mRNA compared to male patients (p < 0.05) and male IBS-D patients had higher IBS symptom severity scores and lower BDNF mRNA and protein levels compared to male controls (p < 0.05). Scatter plot showed a significant negative correlation between IBS-SSS and BDNF mRNA levels in the cohort of male IBS-D patients and their male controls (p < 0.05). We detected a high proportion of gastrointestinal surgery in IBS patients and confirmed food intolerances and psychiatric diseases as common comorbidities. Although in a small sample, we demonstrated that BDNF is detectable in human descending colon, with higher BDNF mRNA levels in female IBS patients compared to males and lower mRNA and protein levels in male IBS-D patients compared to male controls. Further research should be directed toward subgroups of IBS since their etiologies might be different.

A Randomized Placebo-Controlled N-of-1 Trial: The Effect of Proton Pump Inhibitor in the Management of Gastroesophageal Reflux Disease. Can J Gastroenterol Hepatol 2019; 2019:3926051.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is the most frequent chronic gastrointestinal disorder. It is defined as a condition developed when the reflux of gastric contents causes troublesome symptoms (heartburn and regurgitation). This requires adequate treatment since it can lead to long-term complications including esophagus adenocarcinoma. Proton pump inhibitors (PPI) are generally used to treat GERD due to their high-security profile and efficiency on most patients. However, recurrent reflux despite initial treatment is frequent. N-of-1 trial is a study that allows the identification of the best treatment for each patient. The objective of this study is to compare the efficacy of standard dose with double dosage of esomeprazole, to improve the GERD symptoms in a single patient. METHODS A single-patient trial, placebo-controlled, randomized, double-blind, was carried out from September 25th, 2012, to April 26th, 2013. It included one outpatient at the gastroenterology service in a fourth-level hospital, diagnosed with nonerosive reflux disease (NERD). Yet, his symptoms were heartburn and reflux, and his endoscopic results were normal esophageal mucosa, without hiatal hernia, though pathological pH values. A no-obese male without any tobacco or alcohol usage received esomeprazole 40 mg/day and 40 mg/bid for 24 weeks. A standardized gastroesophageal reflux disease questionnaire (GerdQ) was used weekly to evaluate symptom frequency and severity. The consumption of 90% of the capsules was considered as an adequate treatment adherence. D'agostino-Pearson and Wilcoxon test were used to determine normal or nonnormal distribution and compare both treatments, respectively, both with a significant statistical difference of p < 0.05. RESULTS The patient completed the study with 96% of adherence. The double dosage of esomeprazole did not improve the control of symptoms compared with the standard dosage. Mean symptomatic score was 9.5±0.5 and 10.2±0.6 for each treatment, respectively (p > 0.05). CONCLUSION There was no significant improvement in the patient GERD symptoms increasing the dose of oral esomeprazole during the 6 months of study. N-of-1 trials in chronic pathologies including GERD are recommended due to their potential value as systematic methods that evaluate therapies without strong scientific evidence.

Abstract
Irritable bowel syndrome (IBS) and gastroesophageal reflux disease (GERD) overlap. It is not clear whether GERD is caused by non-erosive esophagitis, or erosive esophagitis. The Rome criteria are not widely used for the diagnosis of IBS in the clinic. In total, 1,489 IBS patients without red flags were included in the present retrospective study. They comprised of 1,331 females and 158 males with a mean age of 51 years. The diagnosis of IBS was verified by endoscopic and histopathological examinations. Whereas erosive esophagitis occurred in 97% of patients, only 66% had GERD symptoms. Endoscopy and histopathological examinations revealed that 1.4% of the IBS patients with diarrhea as the predominant symptom had other organic gastrointestinal diseases: 0.3% with celiac disease, 0.2% with Crohn's disease, 0.07% with ulcerative colitis, 0.6% with microscopic colitis, and 0.2% with colon cancer. Applying the Rome III criteria produced a sensitivity of 100% [95% confidence intervals (CI)=99.8–100.0%] a specificity of 98.7% (95% CI=98.0–99.2%), a positive likelihood ratio of 76.9%, and a negative likelihood ratio of 0%. IBS is associated with erosive esophagitis. Applying Rome III criteria without red flags and history, was effective in diagnosing IBS. Celiac disease and microscopic colitis should be considered as alternative diagnoses.

Abstract
The Montreal definition of gastroesophageal reflux disease (GERD) provided a rationale for acid suppression medication without investigation, thus enhancing the management of the substantial symptom burden in these patients. Increased proton-pump inhibitor use has also highlighted their limitations, with one third of "typical" symptoms known to be refractory. Most refractory symptoms are ascribed to reflux hypersensitivity (RH) and functional heartburn (FH). RH may be caused by impaired esophageal mucosal barrier function and sensitization of peripheral esophageal receptors. Central sensitization may also contribute to the perception of non-pathologic reflux in RH, and the perception of physiological stimuli in FH. Importantly, mechanisms underlying GERD, RH, and FH are (in theory) not mutually exclusive, further complicating patient management. Methods used to distinguish GERD from RH and FH are impractical for use in epidemiological studies and pragmatic care and may have limited diagnostic accuracy. This is impeding accurate prevalence estimates and risk factor determination and the identification of new therapies. Direct assessment of mucosal barrier function by measuring impedance is a promising candidate for improved diagnosis. Ultimately though the concept of GERD as a composite, symptom-based entity needs re-evaluation, so that new understandings of upper GI symptoms can direct more precise management.

Abstract
BACKGROUND Proton pump inhibitors (PPIs) are potent inhibitors of acid secretion and are the mainstay of therapy for gastroesophageal reflux disease (GERD). Initially designed to be taken 30 min before the first daily meal, these agents are commonly used suboptimally, which adversely affects symptom relief. No study to date has assessed whether correcting dosing regimens would improve symptom control. The objective of this study was to determine whether patients with persistent GERD symptoms on suboptimal omeprazole dosing experience symptomatic improvement when randomized to commonly recommended dosing regimen and to evaluate the economic impact of suboptimal PPI dosing in GERD patients. METHODS Patients with persistent heartburn symptoms ≥ 3 times per week treated with omeprazole 20 mg daily were enrolled and randomized to commonly recommended dosing or continued suboptimal dosing of omeprazole. The primary outcomes were changes in symptom, frequency, and severity, as determined using the Gastroesophageal Reflux Disease Symptom Assessment Scale (GSAS) 4 weeks after the intervention was administered. In secondary analysis, an alternative measure of symptom load was used to infer potential costs. RESULTS Sixty-four patients were enrolled. GSAS symptom, frequency, and severity scores were significantly better when dosing was optimized for overall and heartburn-specific symptoms (P < 0.01 for all parameters). Cost savings resulting from reduced medical care and workplace absenteeism were estimated to be $159.60 per treated patient, with cost savings potentially exceeding $4 billion annually in the USA. DISCUSSION Low-cost efforts to promote commonly recommended PPI dosing can dramatically reduce GERD symptoms and related economic costs. ClinicalTrials.gov, number: NCT02623816.

Lei WY, Chang WC, Wen SH, Wong MW, Hung JS, Yi CH, Liu TT, Hsu CS, Orr WC, Vaezi MF, Pace F, Hsieh TC, Chen CL. Impact of concomitant dyspepsia and irritable bowel syndrome on symptom burden in patients with gastroesophageal reflux disease. J Formos Med Assoc 2018; 118:797-806. [PMID: 30584006 DOI: 10.1016/j.jfma.2018.12.002] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2018] [Revised: 09/20/2018] [Accepted: 12/04/2018] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Patients with gastroesophageal reflux disease (GERD) frequently report symptoms like dyspepsia or/and irritable bowel syndrome (IBS). The aim of the study was to investigate the impact of symptom overlap on GERD symptom burden. We also investigate whether GERD overlapping dyspepsia or/and IBS would have different clinical and psychological features as compared with GERD alone. METHODS A total of 2752 subjects were screened from a health check-up population. We compared the clinical and psychological factors among subjects with GERD alone and with overlap of two or all three diseases. All participants underwent an evaluation with questionnaires including Reflux Disease Questionnaire score, Pittsburgh Sleep Quality Index, Taiwanese Depression Questionnaire, and State-Trait Anxiety Inventory before receiving endoscopic exam. RESULTS Among the GERD population, we identified 26 with IBS (GERD-IBS), 60 with dyspepsia (GERD-D), and 25 subjects with overlap of all three conditions (GERD-D-IBS). GERD-D and GERD-D-IBS subjects had more severe GERD symptoms as compared subjects with GERD alone (p < 0.001). Subjects with overlapping dyspepsia or/and IBS showed a significant increase in the severity of depression and poorer sleep quality than subjects with GERD alone. Notably, anxiety scores did not differ significantly between subjects with overlapping diseases and GERD alone. CONCLUSION Our study demonstrates that disease overlap in GERD population is associated with greater symptom burden, higher depression and poorer sleep quality, but not with anxiety. This study highlights the importance of identifying overlapping conditions as a therapeutic strategy for better management of GERD.

The overlap syndrome of urticaria and gastroesophageal reflux disease. PLoS One 2018; 13:e0207602. [PMID: 30458030 PMCID: PMC6245739 DOI: 10.1371/journal.pone.0207602] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2018] [Accepted: 11/02/2018] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND One-quarter of systemic symptoms associated with chronic spontaneous urticaria (CSU) are related to gastrointestinal complaints (GICs). OBJECTIVES To investigate the prevalence and features of urticaria-overlapping GICs. METHODS In this retrospective cross-sectional survey, 1426 consecutive outpatients were observed at our University Department. Only patients suffering from urticaria or GICs with a complete diagnostic work-up including serum total IgE level (Tot-IgE), differential blood count and urticaria activity score (UAS), were evaluated. RESULTS Among different GICs, gastroesophageal reflux disease (GERD) was the most frequent syndrome observed (15.4%; 95%CI: 13.6-17.3). The prevalence of overlap syndrome for urticaria and GERD was 5.9% (95%CI: 4.7-7.2). In urticaria-patients, the prevalence of GERD was four-fold higher than in patients without hives (44% vs. 11%, p<0.001). UAS was significantly higher in urticaria and GERD overlap syndromes vs. isolated urticarias. In patients with GERD or acute/chronic urticaria or overlap syndrome, Tot-IgE and eosinophil blood count (EBC) differed significantly, with a stepwise increase in their values; from the subgroup of patients with GERD only, to that with overlap of CSU to GERD. Prevalence values for urticaria overlapping with GERD were three- and two-fold higher in CSU and in long-duration GERD cases respectively compared to acute urticaria or short-duration GERD cases. Similar to Th2 pathology models, CSU and GERD overlap syndrome was significantly and independently associated with Total-IgE ≥100IU/ml or EBC ≥250/mmc compared to CSU or GERD. Endoscopic/bioptic findings of non-erosive reflux disease (NERD) or Barrett's esophagus (BE) were more frequent in chronic overlap syndrome than in GERD-patients. CONCLUSIONS GERD was the most frequent GIC in patients with urticaria. Overlap syndrome was more frequent among patients with CSU, where this syndrome was associated with higher values of UAS, Tot-IgE, EBC and frequencies of NERD and BE. These results suggest that overlap syndrome is frequently a chronic syndrome with a Th2-like profile.

Abstract
Several studies have indicated an overlap between gastroesophageal reflux disease (GERD) and various functional gastrointestinal disorders (FGIDs). The overlapping conditions reported have mainly been functional dyspepsia (FD) and irritable bowel syndrome (IBS). The available literature is frequently based on symptomatic questionnaires or endoscopic procedures to diagnose GERD. Rarely, among patients with heartburn, pathophysiological evaluations have been considered to differentiate those with proven GERD from those without. Moreover, both GERD and IBS or FD showed enormous heterogeneity in terms of the criteria and diagnostic procedures used. The GERD-IBS overlap ranges from 3-79% in questionnaire-based studies and from 10-74% when GERD has been diagnosed endoscopically. The prevalence of functional dyspepsia (after normal upper endoscopy) is 12-15% and an overlap with GERD has been reported frequently. Only a few studies have considered a potential overlap between functional heartburn (FH) and IBS using a 24-h pH-metry or impedance-pH evaluation. Similar data has been reported for an overlap between FH and FD. Recently, a revision of the Rome criteria for esophageal FGIDs identified both FH and hypersensitive esophagus (HE) as potential functional esophageal disorders. This might increase the potential overlap between different FGIDs, with FH and HE rather than with GERD. The aim of the present review article was to appraise and discuss the current evidence supporting the possible concomitance of GERD with IBS and FD in the same patients and to evaluate how various GERD treatments could impact on the quality of life of these patients.

Abstract
BACKGROUND although a number of factors have been associated with a deterioration in quality of life in gastroesophageal reflux disease, it is not known which has an independent influence. OBJECTIVE to evaluate factors independently associated with the impact of gastroesophageal reflux disease on health-related quality of life. METHODS a post-hoc analysis of a prospective cohort of patients diagnosed with gastroesophageal reflux disease was performed. The patients completed validated questionnaires to evaluate health-related quality of life (SF 36), gastroesophageal reflux disease (GERQ) and psychological factors (STAI and SCL 90R). RESULTS the study included 98 patients. The univariate analysis showed that a deterioration in the physical component of the SF36 was significantly associated with female gender, educational level, age, weight loss, severity of typical symptoms, supraesophageal symptoms and monthly income. The mental component was significantly associated with alcohol consumption, epigastric pain and lower scores on the STAI and SCL90 questionnaires. The multivariate analysis showed an independent association between the physical component of the SF36 and educational level (β = 0.29; p < 0.01), severity of symptoms (β = -0.38; p < 0.001), body mass index (β = -0.30; p < 0.005), state anxiety (β = 0.28; p < 0.01), female gender (β = -0.23; p < 0.05) and dyspepsia (β = -0.21; p < 0.05). Associated variables within the mental component included state anxiety (β = -0.39; p < 0.01) and depression (β = -0.32; p < 0.05). CONCLUSIONS the principal factors independently associated with a deterioration in health-related quality of life in patients with gastroesophageal reflux disease included the severity of typical symptoms and the presence of dyspepsia. There is also an additional impact of body mass index and the psychological component.

Abstract
BACKGROUND The Rome III diagnostic criteria had been used to diagnose functional gastrointestinal disorders (FGIDs) world wide, and functional bowel disorders (FBDs) including irritable bowel syndrome (IBS) have recently attracted the attention of Japanese physicians. However, there have been few reports on the prevalence of FBDs diagnosed by the Rome III diagnostic criteria. AIMS The aim of this study was to determine the prevalence of FBDs diagnosed according to the diagnostic criteria of Rome III in Japan. PATIENTS AND METHODS All patients who were booked for colonoscopy were enrolled from eight institutions in Japan. This study was a prospective observational study in the period from April 2013 to December 2013. Patients filled out FGID questionnaires of Rome III when they were waiting for colonoscopy. RESULTS Data for 1200 patients who underwent colonoscopy were analyzed. A total of 547 patients (45.6%) were diagnosed with FBDs. Out of those patients, 9.1% had IBS. According to the Rome III diagnostic criteria, 134 patients (11.2%) had functional bloating (FB), 73 (6.1%) had functional constipation (FC), 40 (3.3%) had functional diarrhea (FD), and 191 (15.9%) had unspecified functional bowel disorder (UFBD). Patients with FBDs had significantly higher rates of almost all symptoms (abdominal pain, hard or lumpy stools, loose or watery stools, and bloating) than those in the controls. CONCLUSIONS In Japan, the prevalence of FBDs and IBS is high, similar to that in the US. Many patients with FBDs have multiple symptoms.

Abstract
BACKGROUND: Gastric reflux is one of the most important causes of the referral of patients to the internal clinic, which in some cases causes problems for patients due to resistance to common treatments. Therefore, timely diagnosis and treatment of this group of patients are very important. AIM: The purpose of the present study was to determine the off-proton pump inhibitor (off-PPI) 24 h pH-impedance analyses in patients with refractory gastroesophageal reflux disease (GERD) attending to Taleghani Hospital since 2009 to 2017. METHODS: In this observational descriptive-comparative off-PPI study, 572 patients with refractory GERD who were referred to Taleghani Hospital in Tehran from 2009 to 2017 were selected, and the results of 24 h pH Impedance analysis were then assessed. RESULTS: The results of 24h pH-impedance indicated that 7% of cases belonged to Pure Acid Reflux followed by weakly Acid (1%), non-acid (0.3%), mixed & gas (5.2%), functional (58.4%) and oesophagal hypersensitivity (28%). Furthermore, weakly acid plus acid was also found to be 8% and Weakly Acid + Acid + Non-Acid were determined as 8.3%. CONCLUSIONS: Our findings suggested that nearly more than half of the patients with refractory GERD would have a functional disorder in the 24h pH-impedance analysis.

Abstract
OBJECTIVES Gastro-oesophageal reflux symptoms are common in the community, but there has been no definitive systematic review and meta-analysis of data from all studies to estimate their global prevalence, or potential risk factors for them. DESIGN Medline, Embase and Embase Classic were searched (until September 2016) to identify population-based studies that reported the prevalence of gastro-oesophageal reflux symptoms in adults (≥15 years); gastro-oesophageal reflux was defined using symptom-based criteria or questionnaires. The prevalence was extracted for all studies, and according to the criteria used to define it. Pooled prevalence, according to study location and certain other characteristics, OR and 95% CIs were calculated. RESULTS Of the 14 132 citations evaluated, 102 reported the prevalence of gastro-oesophageal reflux symptoms in 108 separate study populations, containing 460 984 subjects. Prevalence varied according to country (from 2.5% in China to 51.2% in Greece) and criteria used to define gastro-oesophageal reflux symptoms. When only studies using a weekly frequency of heart burn or regurgitation to define presence were considered, pooled prevalence was 13.3% (95% CI 12.0% to 14.6%). Prevalence was higher in subjects ≥50 years (OR 1.32; 95% CI 1.12 to 1.54), smokers (OR 1.26; 95% CI 1.04 to 1.52), non-steroidal anti-inflammatory drug (NSAID)/aspirin users (OR 1.44; 95% CI 1.10 to 1.88) and obese individuals (OR 1.73; 95% CI 1.46 to 2.06). CONCLUSIONS The prevalence of gastro-oesophageal reflux symptoms varied strikingly among countries, even when similar definitions were used to define their presence. Prevalence was significantly higher in subjects ≥50 years, smokers, NSAID users and obese individuals, although these associations were modest.

Prevalence of Dyspepsia in Individuals With Gastroesophageal Reflux-Type Symptoms in the Community: A Systematic Review and Meta-analysis. Clin Gastroenterol Hepatol 2018; 16:39-48.e1.

Abstract
BACKGROUND & AIMS Dyspepsia and gastroesophageal reflux are highly prevalent in the general population, but they are believed to be separate entities. We conducted a systematic review and meta-analysis to estimate the prevalence of dyspepsia in individuals with gastroesophageal reflux symptoms (GERS), and to quantify overlap between the disorders. METHODS We searched MEDLINE, EMBASE, and EMBASE Classic databases to identify population-based studies reporting the prevalence of dyspepsia and GERS in adults, defined using specific symptom-based criteria or based on answers to questionnaires. We calculated pooled prevalence values, according to study location and criteria used to define weekly GERS or dyspepsia, as well as odds ratios (ORs) with 95% CIs. The degree of overlap between dyspepsia and GERS was examined. RESULTS Of 14,132 papers evaluated, 79 reported prevalence of weekly GERS. Nineteen of these study populations, comprising 111,459 participants, also reported the proportion of individuals with dyspepsia. The prevalence of dyspepsia in individuals with weekly GERS was 43.9% (95% CI, 35.1%-52.9%). The pooled OR for dyspepsia in individuals with weekly GERS, compared with those without, was 6.94 (95% CI, 4.33%-11.1%). The OR for dyspepsia in individuals with weekly GERS was significantly higher in all geographical regions studied and for all diagnostic criteria. The pooled degree of overlap between dyspepsia and GERS was 25.9% (95% CI, 19.9%-32.4%). CONCLUSIONS The odds of dyspepsia in individuals with weekly GERS is almost 7-fold that of individuals without GERS; dyspepsia and GERS overlap in more than 25% of individuals. Reasons for this remain speculative, but might include shared pathophysiological mechanisms or residual confounding factors. However, patients with GERS should be questioned about coexistent dyspepsia, to optimize treatment approaches.

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
OBJECTIVE The aim of this review was to examine (1) the prevalence of smoking in subjects with irritable bowel syndrome (IBS), (2) whether smoking prevalence significantly differs between subjects with and without IBS, and (3) whether smoking significantly predicts the presence or the development of IBS. METHODS Articles were retrieved by systematically searching the Scopus, Web of Science, and PubMed electronic databases from inception to July 2016, using the keywords "smoking" and "tobacco" combined with "irritable bowel syndrome." Reference lists of included articles were also searched. Articles were included if they (1) reported data on smoking prevalence in subjects with IBS and/or on the association (assessed by means of multivariate analyses) between smoking and IBS, (2) identified IBS according to Manning criteria or Rome I-III criteria, (3) were English-language articles, and (4) involved only adult subjects. RESULTS The electronic searches yielded a total of 1,637 records, and 42 articles met inclusion criteria. Another 13 articles were retrieved through manual search, leading to a total of 55 included articles. Smoking prevalence in subjects with IBS was assessed by 48 articles and ranged from 0% in university students to 47.1% in patients with microscopic colitis. Thirty-three articles compared smoking prevalence between subjects with and without IBS. In 25 articles no significant difference was found. In seven articles smoking was significantly more frequent in subjects with IBS compared to those without IBS, while one study found a significantly higher smoking prevalence in controls. Eighteen multivariate analyses assessing the association between smoking and IBS were presented in 16 articles. Only one study employed a prospective design. In 11 analyses, smoking was not significantly associated with IBS after adjusting for covariates. In seven studies smoking independently predicted the presence of IBS. CONCLUSIONS According to the selected articles, a significant association between smoking and IBS cannot be confirmed. However, different shortcomings may hinder generalizability and comparability of many studies. A dimensional assessment of smoking, a prospective design, the differentiation between IBS subgroups, and the recruitment of patients in clinical settings, especially in primary care, are necessary to clarify the role of smoking in IBS.

Abstract
A large variety of foregut symptoms can occur in patients with gastroesophageal reflux disease (GERD), which can overlap with other disorders such as somatoform disorders and dyspepsia. Due to unclear diagnostic situations, these patients are often not adequately treated. The aim of this study was the evaluation of patients with foregut symptoms, referred for possible antireflux surgery, regarding their relationship with GERD and somatization tendencies based on control data from an unselected population. Symptom evaluation and somatization screening were initiated both in volunteers and in patients with foregut symptoms and GERD. Unselected volunteers from a village population were also evaluated by symptom analysis and for somatisation tendency. In addition, patients with foregut symptoms were diagnosed for GERD, and symptom analysis and psychodiagnostic evaluation were performed. There is no major significant difference in the symptom-spectrum in patients with foregut symptoms, whether they have a proven pathologic acid exposure from GERD or not. The probability for the risk of somatization was 5.6% in the unselected population of nonpatient volunteers (n = 267). In patients with foregut symptoms (n = 750), the probability for the presence of somatoform tendencies was approximately 20%, independent whether these patients had a documented GERD or a normal esophageal acid exposure, implicating further diagnostic work-up for the selection of patients for antireflux surgery. There is a remarkable symptom load and variety in patients with GERD, in patients with foregut symptoms, and in an unselected population of volunteers. There is no difference in the risk for somatization between patients with foregut symptoms and those with documented GERD. Therapeutic decision making especially prior to antireflux surgery requires an awareness of mental and emotional challenges.

Abstract
BACKGROUND It is unknown why functional gastrointestinal disorders (FGIDs) overlap and limited information exists on risk factors for those with overlap. Our aim was to estimate the prevalence of combinations of FGIDs including reflux (FGIDs-gastroesophageal reflux [GER]), and evaluate potential risk factors for people with multiple disorders in a representative US community. METHODS A population-based study was conducted by mailing a valid GI symptom questionnaire to an age- and gender-stratified random sample of residents of Olmsted County, MN. Rome III definitions were used to identify people with FGIDs, and GER was defined by weekly or more frequent heartburn or acid regurgitation. The prevalence of people meeting multiple symptom complexes was estimated. Moreover, potential risk factors for people with multiple disorders were evaluated. KEY RESULTS A total of 3548 people provided data for each of the necessary symptom questions (mean age: 61±16 years, 54% female). Among these 3548 subjects, 2009 (57%) had no FGIDs-GER, 906 (26%) had a pure FGID-GER, 372 (10%) had 2 FGIDs-GER, and 261 (7%) had 3 or more FGIDs-GER. Somatization as assessed by a higher Somatic Symptom Checklist score (OR=3.3, 95% CI [2.7,4.1]) was associated with an increased odds for those with 3 or more FGIDs-GER compared to subjects with a pure FGID-GER adjusting for age and gender. CONCLUSIONS AND INFERENCES Symptom complex overlap is common rather than rare in the community. GER is an integral symptom complex associated with both upper and lower FGIDs. Somatization is a strong risk factor for multiple FGIDs.

Abstract
Some patients with gastro-oesophageal reflux disease (GORD) experience symptoms despite proton pump inhibitor (PPI) treatment. In the early years of their availability, these drugs were thought to be a highly effective treatment for GORD and realisation that symptom relief was often incomplete came as a disappointment. This review considers the evolution of thinking with the aid of the Gartner hype cycle - a graphical depiction of the process of innovation, evolution and adoption of new technologies. Acknowledging that over-simplistic concepts of GORD have been largely responsible for inflated expectations of PPI therapy is an important step forward in establishing how patients with persistent symptoms, despite PPIs, should be assessed and treated.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is classified into subtypes according to bowel habit. OBJECTIVE To investigate whether there are differences in clinical features, comorbidities, anxiety, depression and body mass index (BMI) among IBS subtypes. METHODS The study group included 113 consecutive patients (mean age: 48 ± 11 years; females: 94) with the diagnosis of IBS. All of them answered a structured questionnaire for demographic and clinical data and underwent upper endoscopy. Anxiety and depression were assessed by the Hospital Anxiety and Depression scale (HAD). RESULTS The distribution of subtypes was: IBS-diarrhea (IBS-D), 46%; IBS-constipation (IBS-C), 32%, and mixed IBS (IBS-M), 22%. IBS overlap with gastroesophageal reflux disease (GERD), functional dyspepsia, chronic headache and fibromyalgia occurred in 65.5%, 48.7%, 40.7% and 22.1% of patients, respectively. Anxiety and/or depression were found in 81.5%. Comparisons among subgroups showed that bloating was significantly associated with IBS-M compared to IBS-D (odds ratio-OR-5.6). Straining was more likely to be reported by IBS-M (OR 15.3) and IBS-C (OR 12.0) compared to IBS-D patients, while urgency was associated with both IBS-M (OR 19.7) and IBS-D (OR 14.2) compared to IBS-C. In addition, IBS-M patients were more likely to present GERD than IBS-D (OR 6.7) and higher scores for anxiety than IBS-C patients (OR 1.2). BMI values did not differ between IBS-D and IBS-C. CONCLUSION IBS-M is characterized by symptoms frequently reported by both IBS-C (straining) and IBS-D (urgency), higher levels of anxiety, and high prevalence of comorbidities. These features should be considered in the clinical management of this subgroup.

Abstract
BACKGROUND Functional bowel disorders (FBDs) such as irritable bowel syndrome (IBS) impact on quality of life and health care resources. It is uncertain whether patients with functional digestive symptoms have similar characteristics in different populations. This population-based study assessed the prevalence and identified risk factors for these disorders in South-East China. METHODS Five communities were selected at random and invitations distributed to a representative sample (block randomization). Questionnaires were completely supervised by investigators. Demographic and medical data with FBD symptoms (Rome III criteria), psychological condition, life event stress, and quality of life were collected. KEY RESULTS Functional bowel disorder prevalence was 41.6% in 1999/2115 (94.5%) completed questionnaires: 9.9% functional constipation (FC), 6.8% bloating (FB), 6.5% diarrhea (FD), 5.9% IBS (IBS-D 47.1%, IBS-M 23.9%, IBS-C 12.8%, IBS-U 16.2%), and 12.6% unspecified. Similar numbers of men and women had FBDs or IBS (overall; 51.3% male vs 48.7% female, P=.796); however, there was female predominance in FC (62.1%, P<.001) and FB (58.5%, P=.038). FBDs were associated with greater anxiety, depression, life event stress, and a lower quality of life compared with those without symptoms (all, P<.0001). Logistic regression identified medical co-morbidity, anxiety/depression, and life event stress as independent risk factors for these disorders. CONCLUSIONS & INFERENCES Functional bowel disorders are as common in South China as in western populations. A similar number of men and women report FBDs and IBS. Only FC and FB are more prevalent in females. Independent risk factors associated with FBDs included physical and psychosocial stressors.

Abstract
OBJECTIVES We aimed to evaluate the prevalence of irritable bowel syndrome (IBS) in patients with typical reflux symptoms as distinguished into gastroesophageal reflux disease (GERD), hypersensitive esophagus (HE), and functional heartburn (FH) by means of endoscopy and multichannel intraluminal impedance (MII)-pH monitoring. The secondary aim was to detect pathophysiological and clinical differences between different sub-groups of patients with heartburn. METHODS Patients underwent a structured interview based on questionnaires for GERD, IBS, anxiety, and depression. Off-therapy upper-gastrointestinal (GI) endoscopy and 24 h MII-pH monitoring were performed in all cases. In patients with IBS, fecal calprotectin was measured and colonoscopy was scheduled for values >100 mg/kg to exclude organic disease. Multivariate logistic regression analysis was performed to identify independent risk factors for FH. RESULTS Of the 697 consecutive heartburn patients who entered the study, 454 (65%) had reflux-related heartburn (GERD+HE), whereas 243 (35%) had FH. IBS was found in 147/454 (33%) GERD/HE but in 187/243 (77%) FH patients (P<0.001). At multivariate analysis, IBS and anxiety were independent risk factors for FH in comparison with reflux-related heartburn (GERD+HE). CONCLUSIONS IBS overlaps more frequently with FH than with GERD and HE, suggesting common pathways and treatment. HE showed intermediate characteristic between GERD and FH.

Abstract
Uninvestigated dyspepsia (UD), irritable bowel syndrome (IBS), and gastroesophageal reflux disease (GERD) are common disorders universally. Many studies have assessed their epidemiological characteristics around the world. However, such information is not known for Syria. We aim to estimate the epidemiologic characteristics and possible risk factors for UD, IBS, and GERD among students at Damascus University, Damascus, Syria. A cross-sectional study was conducted in July-September 2015 at a campus of Damascus University. A total of 320 students were randomly asked to complete the survey. We used ROME III criteria to define UD and IBS, and Montreal definition for GERD. In total, 302 valid participants were included in the analysis. Prevalence for UD, IBS, and GERD was 25%, 17%, and 16%, respectively. Symptom overlap was present in 46 students (15%), with UD+IBS in 28 (9.3%), UD+GERD in 26 (8.6%), and IBS+GERD in 14 (4.6%) students. Eleven (3.6%) students had symptoms of UD+IBS+GERD. Each of these overlaps occurred more frequently than expected by chance. Significant risk factors included cigarettes smoking, waterpipe consumption, and body mass index <18.5kg/m2 for UD; female gender and three cups of coffee/d for IBS; and two cups of tea and one to five cigarettes/d for GERD. Risk factors for these disorders remain poorly characterized and need further investigations.

Abstract
It is important to understand sex and gender-related differences in gastroesophageal reflux disease (GERD) because gender-related biologic factors might lead to better prevention and therapy. Non-erosive reflux disease (NERD) affects more women than men. GERD symptoms are more frequent in patients with NERD than in those with reflux esophagitis. However, men suffer pathologic diseases such as reflux esophagitis, Barrett’s esophagus (BE), and esophageal adenocarcinoma (EAC) more frequently than women. The prevalence of reflux esophagitis is significantly increased with age in women, especially after their 50s. The mean age of EAC incidence in women is higher than in men, suggesting a role of estrogen in delaying the onset of BE and EAC. In a chronic rat reflux esophagitis model, nitric oxide was found to be an aggravating factor of esophageal injury in a male-predominant way. In addition, the expression of esophageal occludin, a tight junction protein that plays an important role in the esophageal defense mechanism, was up-regulated in women. This explains the male predominance of reflux esophagitis and delayed incidence of BE or EAC in women. Moreover, the symptoms such as heartburn, regurgitation, and extra-esophageal symptoms have been more frequently reported by women than by men, suggesting that sex and gender play a role in symptom perception. Differential sensitivity with augmented symptoms in women might have diagnostic and therapeutic influence. Furthermore, recent studies have suggested that hormone replacement therapy has a protective effect against esophageal cancer. However, an anti-inflammatory role of estrogen remains compelling, which means further study is necessary in this area.

Abstract
Background/Aims Few studies are available that have investigated the risk factors for overlapping irritable bowel syndrome (IBS)-like symptoms in patients with inactive inflammatory bowel disease (IBD). The present study has 3 objectives: (1) to assess the prevalence of IBS-like symptoms in Japanese patients with inactive IBD using Rome III criteria, (2) to examine the relationship of IBS-like symptoms to health related quality of life (HR-QOL), and (3) to investigate associations for developing IBS-like symptoms in patients with inactive IBD. Methods IBS-like symptoms were evaluated using the Rome III questionnaire for functional gastrointestinal disorders. HR-QOL and hospital anxiety and depression scale were evaluated. Results IBS-like symptoms were found in 17.5% (7/40) of patients with inactive ulcerative colitis, 27.1% (29/107) of patients with inactive Crohn’s disease (CD), and 5.3% (23/438) of healthy control subjects. The QOL level was significantly lower and anxiety score was significantly higher in inactive CD patients with IBS-like symptoms than in those without such symptoms (P = 0.003, P = 0.009). Use of anti-anxiety drugs was associated with the presence of IBS symptoms (P = 0.045). HR-QOL score was lower and anxiety score was higher in patients with inactive ulcerative colitis, but the difference was not statistically significant. Conclusions The prevalence of IBS-like symptoms in inactive IBD patients was significantly higher than in healthy controls. Inactive CD patients with IBS-like symptoms has low QOL and anxiety; suggesting that anxiety may be associated with symptom development in such patients.

Abstract
About one-third of patients with suspected gastro-oesophageal reflux disease (GERD) do not respond symptomatically to proton pump inhibitors (PPIs). Many of these patients do not suffer from GERD, but may have underlying functional heartburn or atypical chest pain. Other causes of failure to respond to PPIs include inadequate acid suppression, non-acid reflux, oesophageal hypersensitivity, oesophageal dysmotility and psychological comorbidities. Functional oesophageal tests can exclude cardiac and structural causes, as well as help to confi rm or exclude GERD. The use of PPIs should only be continued in the presence of acid reflux or oesophageal hypersensitivity for acid reflux-related events that is proven on functional oesophageal tests.

Abstract
BACKGROUND Little is known about the direction of causality among asthma, posttraumatic stress disorder (PTSD), and onset of gastroesophageal reflux symptoms (GERS) after exposure to the 9/11/2001 World Trade Center (WTC) disaster. METHODS Using data from the WTC Health Registry, we investigated the effects of early diagnosed post-9/11 asthma and PTSD on the late onset and persistence of GERS using log-binomial regression, and examined whether PTSD mediated the asthma-GERS association using structural equation modeling. RESULTS Of 29,406 enrollees, 23% reported GERS at follow-up in 2011-2012. Early post-9/11 asthma and PTSD were each independently associated with both the persistence of GERS that was present at baseline and the development of GERS in persons without a prior history. PTSD mediated the association between early post-9/11 asthma and late-onset GERS. CONCLUSIONS Clinicians should assess patients with post-9/11 GERS for comorbid asthma and PTSD, and plan medical care for these conditions in an integrated fashion. Am. J. Ind.

Abdominal bloating is the most bothersome symptom in irritable bowel syndrome with constipation (IBS-C): a large population-based Internet survey in Japan. Biopsychosoc Med 2016; 10:19.

Abstract
Background Abdominal bloating is a common symptom in patients with irritable bowel syndrome with constipation (IBS-C). However, it is not included among the required items in the Rome III diagnostic criteria for IBS. Little is known about an impact of abdominal bloating seen in patients with IBS-C. Using a large population-based sample, the aim of the present study was to investigate what is the most bothersome symptom in subjects with IBS-C. Methods An Internet survey of 30,000 adults drawn from the general public throughout Japan was conducted to identify subtypes of IBS using the Rome III diagnostic questionnaire. Consecutively, the screened subjects with IBS-C and the same number of age- and sex-matched non-IBS subjects who were randomly selected as controls were asked to answer a questionnaire on the degree of anxiety they experienced in their daily lives, thoughts about bowel habit, and their dominant gastrointestinal symptoms together with exacerbation factors (for IBS-C only). Results The screening survey showed that the prevalence of overall IBS was 16.5 % (female 17.4 %, male 15.5 %) and that 2.8 % met the criteria for IBS-C, 4.5 % for IBS with diarrhea (IBS-D) and 8.2 % for mixed IBS (IBS-M). Seven hundred and fifty-nine of 835 (90.9 %) subjects with IBS-C and 746 of 830 (89.9 %) control subjects completed the consecutive questionnaire. IBS-C subjects felt a higher degree of anxiety in their daily lives (p < 0.01) and considered bowel habit to be an indicator of health (p < 0.01) to a greater extent than control subjects. In IBS-C, the degree of anxiety was significantly associated with abdominal discomfort (p < 0.01), pain (p < 0.01) and bloating (p = 0.02), but not with the frequency of bowel habit (p > 0.1). Abdominal bloating was the most bothersome symptom (27.5 %), which was more likely to occur after a meal (52.2 %), at work/school (29.2 %) and during times of stress (26.8 %). Only 4.5 % of IBS-C subjects reported abdominal pain as the ‘most bothersome’ symptom. Conclusions A large population-based Internet survey suggests that abdominal bloating has a great impact on the daily lives of subjects diagnosed with IBS-C. Not only bowel movement/abdominal pain but also abdominal bloating should be evaluated in patients with IBS-C.

Abstract
BACKGROUND Although 2% to 4% of the population develop gastroesophageal reflux disease (GERD) annually, factors associated with the onset of GERD are scarcely known. OBJECTIVE To assess whether such factors include weight gain and psychological distress. METHODS Two cohorts (first: N=222; second N=754) drawn from 2 case-control studies were followed up for around 5 years. In 2004, all participants were directly interviewed using a validated questionnaire to collect data on body weight, height, GERD symptoms, and psychological distress. In 2009 to 2010, these same participants were again interviewed using the same methodology. RESULTS The response rate was 83.3% in cohort 1 and 39.1% in cohort 2, after a follow-up of 4.3±0.7 and 5.6±0.3 years, respectively. The multivariate analysis showed only weight gain and psychological distress as being independently associated with the onset of GERD in both cohorts. Weight gain per kilogram showed an adjusted odds ratio (OR) of 1.21 (1.01-1.44) in the first cohort, and a gain of 5 kg or more showed an adjusted OR of 4.65 (1.72-12.53) in the second. Somatization scores showed an adjusted OR of 1.09 (1.04-1.15) in the first cohort (measured as Minnesota Multiphasic Personality Inventory 2 hypochondriasis score) and 2.88 (1.04-8.02) in the second (measured as psychosomatic symptoms score). Body mass index on attaining overweight or obese status was associated with the onset of GERD in the unadjusted but not in the adjusted analysis. CONCLUSIONS Weight gain and somatization are the main factors associated with the onset of GERD. The association between GERD and obesity is just the ultimate consequence of gaining weight.

Abstract
Background Regulatory and treatment guidelines focus on individual conditions, yet clinicians often see patients with overlapping conditions. Objective This cross-sectional survey study assesses the impact of overlapping functional dyspepsia (FD), gastroesophageal reflux disease (GERD), irritable bowel syndrome with constipation (IBS-C), and chronic idiopathic constipation (CIC) on symptom burden and consulting behavior. Methods Survey participants met Rome III criteria for FD, IBS-C, and/or CIC, and/or reported GERD; participants answered questions about symptom frequency and bothersomeness, work and productivity, and consulting behavior. Results Of 2641 respondents, 1592 (60.3%) had one condition; 832 (31.5%) had two; and 217 (8.2%) had three; 57.3% of 1690 FD, 54.6% of 1337 GERD, 82.6% of 328 IBS-C, and 62.5% of 552 CIC respondents had condition overlap. Overall GI symptoms were very/extremely bothersome in 28.6% of single-condition respondents, 50.7% of two-condition, and 69.6% of three-condition respondents (p < 0.001, chi square). Symptom frequency and productivity losses both increased with condition overlap. Over 12 months, 43.7% of single-condition, 49.9% of two-condition, and 66.5% of three-condition respondents consulted a physician about GI symptoms (p < 0.001, chi square). Conclusion Functional GI disorders frequently overlap with each other and with GERD. Condition overlap is associated with greater symptom burden and increased physician consultations.

Abstract
OBJECTIVE This study aimed to investigate the prevalence of the overlap between gastroesophageal reflux disease (GERD) and functional bowel disorders (FBD) in the general population in rural areas in China. METHODS A population-based cross-sectional study was conducted in six villages in Nanmazhuang area in Lankao County (Henan Province, China) from December 2010 to October 2011. The GERD questionnaire (GerdQ) and Rome III criteria were used for the diagnosis of GERD and FBD and to determine the prevalence of GERD-FBD overlap. RESULTS The response rate to the questionnaires of the patients was 91.5%. In all, 2950 of 3700 residents with a mean age of 42.4 ± 16.8 years were included. Among them, 4.8% were diagnosed with GERD and 4.6% with FBD. The proportion of respondents with FBD was significantly higher in the GERD group than that in the non-GERD group (25.53% vs 3.60%, P < 0.05). The prevalence of GERD in the FBD group was significantly higher than that in the non-FBD group (26.28% vs 3.73%, P < 0.05). The prevalence of GERD-FBD overlap in the general rural population was 1.22%. Logistic regression analysis indicated that anxiety was an independent predictor for the GERD-FBD overlap in GERD and FBD (odds ratio [OR] 1.05, 95% confidence interval [CI] 1.02-1.09 and OR 1.06, 95% CI 1.02-1.10, respectively). CONCLUSION GERD-FBD overlap is more common than expected by chance in the general rural population, and anxiety is significantly related to the overlap.

Abstract
Functional gastrointestinal disorders (FGIDs), represented by functional dyspepsia (FD) and irritable bowel syndrome (IBS), are a group of disorders that include variable combinations of chronic or recurrent gastrointestinal symptoms not explained by structural or biochemical abnormalities. FGIDs account for a significant percentage of patients seen in primary care settings with abdominal symptoms. Although the definition of FGIDs can easily affect the prevalence, the prevalences of dyspepsia/FD and IBS diagnosed by the Rome III criteria in the general population are 5.3–20.4% and 1.1–29.2%, respectively. Recent reports of FD and IBS defined by the Rome III criteria indicated a female predominance. Regarding the subtype prevalence of FD, postprandial distress syndrome was more prevalent than epigastric pain syndrome (5.6–13.9% vs 0.9–9.5%). The subtype prevalence of IBS is characterized by male predominance for IBS with diarrhea and female predominance for IBS with constipation. Factors affecting the development of FGIDs such as epidemiological factors including genetic and environmental factors, are important. Gene polymorphisms are involved in the development of FGIDs. The prevalence differs among races and geographic areas. Foods may affect the development of FGIDs, but the causal relationships between food and FGIDs are not conclusive. The symptoms often regress and appear in the course of these entities. Building a favorable patient-doctor relationship is effective for controlling symptoms of FGIDs. Physicians should explain that FGIDs are highly prevalent conditions, impair the patients’ quality of life even without evident underlying organic causes and are not life-threatening conditions to ensure patients’ understanding.

Abstract
OBJECTIVE Functional somatic syndromes (FSSs) have often been linked to psychopathology. The aim of the current study was to compare prevalence rates of psychiatric disorders among individuals with chronic fatigue syndrome (CFS), fibromyalgia (FM), and irritable bowel syndrome (IBS). METHODS This study was conducted in 94,516 participants (mean [standard deviation] age = 44.6 [12.5] years, 58.7% women) of the general-population cohort LifeLines. FSSs were assessed by self-reports. Mood disorders (i.e., major depressive disorder and dysthymia) and anxiety disorders (i.e., generalized anxiety disorder, social phobia, panic disorder with/without agoraphobia, and agoraphobia) were assessed by means of the Mini International Neuropsychiatric Interview. Risks on psychiatric disorders were compared for individuals with CFS, FM, and IBS by using logistic regression analyses adjusted for age and sex. RESULTS Prevalence rates of CFS, FM, and IBS were 1.3%, 3.0%, and 9.7%, respectively. Individuals with CFS, FM, and IBS had significantly more mood (odds ratios [ORs] = 1.72-5.42) and anxiety disorders (ORs = 1.52-3.96) than did individuals without FSSs, but prevalence rates were low (1.6%-28.6%). Individuals with CFS more often had mood (ORs = 2.00-4.08) and anxiety disorders (ORs = 1.63-2.32) than did individuals with FM and IBS. Major depressive disorder was more common in FM than in IBS (OR = 1.58, 95% confidence interval = 1.24-2.01), whereas these groups did not differ on dysthymia or anxiety disorders. CONCLUSIONS Mood and anxiety disorders are more prevalent in individuals with FSSs, and particularly CFS, than in individuals without FSSs. However, most individuals with FSSs do not have mood or anxiety disorders.

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD), functional dyspepsia (FD) and irritable bowel syndrome (IBS) are common functional gastrointestinal conditions with significant impact on the daily lives of individuals. The objective was to investigate the prevalence and overlap of the three conditions in a Western general population. MATERIAL AND METHODS A nationwide study of 100,000 individuals 20 years and above, randomly selected in the general population. A web-based questionnaire survey formed the basis of this study. Questions regarding FD and IBS were extracted from the ROME III adult questionnaire. Questions regarding GERD were developed based on the Montreal definition. Prevalence estimates for GERD, FD IBS were calculated in total and for each sex separately and for four age groups. A Venn diagram was constructed, illustrating the overlap between the three conditions. RESULTS The overall response rate was 52.2%. The prevalence of GERD, FD and IBS was 11.2%, 7.7% and 10.5%, respectively, and overlap between two or three of these conditions was seen among 6.5% of the respondents. Among individuals meeting the criteria of one or more of the conditions GERD, FD and IBS, 30.7% had overlap between two or all three conditions. CONCLUSION GERD, FD and IBS are common conditions in the general population and the overlap between these conditions is also quite common. When diagnosing patients with GERD, FD and IBS, physicians should keep in mind that these patients could be suffering from more than one of these conditions.

Abstract
Limited data exist to determine the prevalence and clinical spectrum of gastroesophageal reflux disease (GERD) in the Russian population, which might be different from those in Western countries. This study was performed in Moscow on randomized 1065 adults aged ≥ 15 years. A validated reflux questionnaire comprising 72 questions and an additional 29 sub-questions were used. The questions assessed (heartburn and regurgitation) and related (dyspepsia, dysphagia, odynophagia and chest pain) symptoms, the triggering factors of these symptoms, family history and data on demographic and socioeconomic features. GERD was defined as heartburn and/or regurgitation once a week or common. Of the 1065 participants, 42.1% were male and 57.9% were female. The prevalences of frequent and occasional symptoms were 17.6 and 22.1% for heartburn and 17.5 and 21.8% for regurgitation, respectively, over the last 12 months. The prevalence of GERD was found to be 23.6%. The rate of GERD was significantly higher in females than in males (15.4 vs. 29.5%, P < 0.001) and significantly increased as the age of the participants increased (P = 0.011). GERD was present in 20.4% of smokers, 24.2% of coffee drinkers, 21.5% of alcohol consumers and 45.9% of stressed participants. Although the rate of alcohol consumers was lower in those with GERD compared with those without GERD, the rate of coffee drinkers and stressed participants was higher among those with GERD. The rate of additional symptoms was higher even in participants complaining of regurgitation/heartburn rarely, compared with those without complaints. Using the same questionnaire, which makes it possible to compare the present results with those from different countries, we found the prevalence of GERD in Moscow to be 23.6%, one of highest in the Western populations. The rates of heartburn and regurgitation were found to be similar, which constitutes a different result than has been found in similar studies. Additional symptoms should be assessed, in all GERD patients even in the presence of rare complaints of regurgitation/heartburn.

Abstract
'Refractory gastroesophageal reflux disease' is one of the most common misnomers in the area of gastroesophageal reflux disease. The term implies reflux as the underlying etiology despite unresponsiveness to aggressive proton pump inhibitor therapy. The term should be replaced with 'refractory symptoms.' We must acknowledge that in many patients symptoms of reflux often overlap with non-GERD causes such as gastroparesis, dyspepsia, hypersensitive esophagus and functional disorders. Lack of response to aggressive acid suppressive therapy often leads to diagnostic testing. In majority of patients these tests are normal. The role of non-acid reflux in this group is uncertain and patients should not undergo surgical fundoplication based on this parameter. In patients unresponsive to acid suppressive therapy GERD is most commonly not causal and a search for non-GERD causes must ensue.
