Abstract
Gastroparesis is a gastrointestinal disorder characterized by significant prolongation of gastric emptying time caused by impaired motility of the stomach. Its estimated prevalence is 24.2 per 100 000 people. However, the prevalence of gastroparesis in Asian countries is unknown due to a limited number of epidemiological studies and significant phenotypic variability of the Asian population in these studies. Analysis of previous research on gastroparesis and functional bowel disorders reveals the possibility of an increased prevalence among Asian individuals. A comparison of ethnic constituents between the recent United Kingdom gastroparesis study and its mother database has demonstrated a higher prevalence of gastroparesis among British Asian patients when compared with British Caucasian patients. An estimated gastroparesis prevalence in the Asian population can be calculated by identifying the individuals who are likely to demonstrate a delayed gastric emptying from all diagnosed functional dyspepsia patients. We suggest that gastroparesis tends to be underdiagnosed in Asians due to a lack of studies on gastroparesis in the Asian continent, a lack of knowledge among practitioners, and poor availability of scintigraphy testing as well as limited therapeutic options for this disease. Given the high probability of Asian predominance in gastroparesis and its disease impact on quality of life, epidemiological research focusing on the Asian population is required.

Innovative preconditioning strategies for improving the therapeutic efficacy of extracellular vesicles derived from mesenchymal stem cells in gastrointestinal diseases. Inflammopharmacology 2023; 31:2973-2993. [PMID: 37874430 PMCID: PMC10692273 DOI: 10.1007/s10787-023-01350-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Accepted: 09/20/2023] [Indexed: 10/25/2023]
Abstract
Gastrointestinal (GI) diseases have become a global health issue and an economic burden due to their wide distribution, late prognosis, and the inefficacy of recent available medications. Therefore, it is crucial to search for new strategies for their management. In the recent decades, mesenchymal stem cells (MSCs) therapy has attracted attention as a viable option for treating a myriad of GI disorders such as hepatic fibrosis (HF), ulcerative colitis (UC), acute liver injury (ALI), and non-alcoholic fatty liver disease (NAFLD) due to their regenerative and paracrine properties. Importantly, recent studies have shown that MSC-derived extracellular vesicles (MSC-EVs) are responsible for most of the therapeutic effects of MSCs. In addition, EVs have revealed several benefits over their parent MSCs, such as being less immunogenic, having a lower risk of tumour formation, being able to cross biological barriers, and being easier to store. MSC-EVs exhibited regenerative, anti-oxidant, anti-inflammatory, anti-apoptotic, and anti-fibrotic effects in different experimental models of GI diseases. However, a key issue with their clinical application is the maintenance of their stability and efficacy following in vivo transplantation. Preconditioning of MSC-EVs or their parent cells is one of the novel methods used to improve their effectiveness and stability. Herein, we discuss the application of MSC-EVs in several GI disorders taking into account their mechanism of action. We also summarise the challenges and restrictions that need to be overcome to promote their clinical application in the treatment of various GI diseases as well as the recent developments to improve their effectiveness. A representation of the innovative preconditioning techniques that have been suggested for improving the therapeutic efficacy of MSC-EVs in GI diseases. The pathological conditions in various GI disorders (ALI, UC, HF and NAFLD) create a harsh environment for EVs and their parents, increasing the risk of apoptosis and senescence of MSCs and thereby diminishing MSC-EVs yield and restricting their large-scale applications. Preconditioning with pharmacological agents or biological mediators can improve the therapeutic efficacy of MSC-EVs through their adaption to the lethal environment to which they are subjected. This can result in establishment of a more conducive environment and activation of numerous vital trajectories that act to improve the immunomodulatory, reparative and regenerative activities of the derived EVs, as a part of MSCs paracrine system.

Abstract
Proton pump inhibitors (PPIs) have been available for over three decades and are among the most commonly prescribed medications. They are effective in treating a variety of gastric acid-related disorders. They are freely available and based on current evidence, use of PPIs for inappropriate indications and duration appears to be common. Over the years, concerns have been raised on the safety of PPIs as they have been associated with several adverse effects. Hence, there is a need for PPI stewardship to promote the use of PPIs for appropriate indication and duration. With this objective, the Indian Society of Gastroenterology has formulated guidelines on the rational use of PPIs. The guidelines were developed using a modified Delphi process. This paper presents these guidelines in detail, including the statements, review of literature, level of evidence and recommendations. This would help the clinicians in optimizing the use of PPIs in their practice and promote PPI stewardship.

Efficacy of Cognitive Behavioral Therapy With Local Wisdom and Web-Based Counseling on Generalized Anxiety Disorders and Functional Gastrointestinal Disorders in Adolescent College Girls: Protocol for a Randomized Controlled Trial. JMIR Res Protoc 2023; 12:e50316. [PMID: 37606989 PMCID: PMC10481218 DOI: 10.2196/50316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 07/21/2023] [Accepted: 07/24/2023] [Indexed: 08/23/2023] Open
Abstract
BACKGROUND The high academic demands experienced by students will often have an impact on the quality of their mental and physical health. The most common health problems reported are gastrointestinal disorders. This condition tends to manifest in the emergence of generalized anxiety disorders (GADs) and reduces the quality of life and productivity. The population that experiences this disorder the most is female adolescents, and this condition occurs in both South African and Indonesian populations. The use of drugs, especially benzodiazepines, often causes psychological conditions as side effects. For this reason, it is necessary to have a solution in the form of a targeted and efficient approach to reduce psychological symptoms that arise from functional gastrointestinal disorders (FGIDs) in the form of anxiety. OBJECTIVE The purpose of this study is to produce and implement a counseling intervention model to assist female students with GADs caused by FGID factors using an approach combining cognitive behavioral therapy (CBT), web-based counseling, and local wisdom in Indonesian and South African populations. METHODS The research subjects will comprise 118 female adolescent students from Indonesia and 118 female adolescent students from South Africa, making a total sample of 236 participants, and the study will use a prospective, parallel randomized controlled trial design. The recruitment process will begin in July 2023, and the trial will begin in August 2023. The posttest assessment data gathering will take place by November 2023. Questionnaires that will be used in this study include the Functional Gastrointestinal Disorder Checklist (FGI-Checklist) to collect data related to FGIDs and the Generalized Anxiety Disorder 7-item (GAD-7) to measure the anxiety conditions experienced by respondents. RESULTS By adopting the intention-to-treat principle, there will be significant mean changes in GAD scores and FGID scores after exposure to this combined approach in the Indonesian and South African populations. Implementing this comprehensive intervention will improve the students' psychological symptoms related to FGIDs and ultimately enhance their overall well-being. CONCLUSIONS This study will develop and implement a model of counseling intervention for female students with GADs obtained from FGIDs using a combination approach to CBT, web-based counseling, and local wisdom in both the Indonesian and South African populations. The trial findings will contribute to our understanding of the effects of CBT combined with local wisdom and web-based counseling approaches that mental health counselors can use to treat GAD-affected adolescent girls who have FGIDs.

Abstract
BACKGROUND Functional dyspepsia (FD) is a common disorder characterized by chronic or recurrent upper abdominal pain or discomfort without any structural abnormalities in the gastrointestinal tract. FD is categorized into two subgroups based on symptoms: postprandial distress syndrome (PDS) and epigastric pain syndrome. SUMMARY The pathophysiology of FD involves several mechanisms. Delayed gastric emptying is observed in approximately 30% of FD patients but does not correlate with symptom patterns or severity. Impaired gastric accommodation is important in the pathophysiology, particularly for PDS. Visceral hypersensitivity, characterized by heightened sensitivity to normal activities, contributes to the perception of discomfort or pain in FD. Alterations to the duodenal mucosa, including impaired mucosal barrier function and low-grade inflammation, are also implicated in the pathogenesis of FD. Microbial dysbiosis and psychological factors such as stress can further exacerbate symptoms. Treatment options include dietary modifications, establishing a physician-patient relationship, acid suppressants, prokinetics, neuromodulators, and behavioral therapies. Dietary recommendations include eating smaller, more frequent meals, and avoiding trigger foods. Acid suppressants are used as the first-line treatment. Prokinetics and neuromodulators aim to improve gastric motility and central pain processing, respectively. Behavioral therapies, including cognitive behavioral therapy and hypnotherapy, have shown benefits for refractory FD. Severe and refractory cases may require combination therapies or experimental treatments. KEY MESSAGES FD is a disorder of gut-brain interaction involving diverse pathophysiological mechanisms. Individualized treatment based on symptoms and responses to interventions is crucial. Further research is needed to improve the understanding of FD and advance the development of effective therapies.

Abstract
The association and interaction between the central nervous system (CNS) and enteric nervous system (ENS) is well established. Essentially ENS is the second brain, as we call it. We tried to understand the structure and function, to throw light on the functional aspect of neurons, and address various disease manifestations. We summarized how various neurological disorders influence the gut via the enteric nervous system and/or bring anatomical or physiological changes in the enteric nervous system or the gut and vice versa. It is known that stress has an effect on Gastrointestinal (GI) motility and causes mucosal erosions. In our literature review, we found that stress can also affect sensory perception in the central nervous system. Interestingly, we found that mutations in the neurohormone, serotonin (5-HT), would result in dysfunctional organ development and further affect mood and behavior. We focused on the developmental aspects of neurons and cognition and their relation to nutritional absorption via the gastrointestinal tract, the development of neurodegenerative disorders in relation to the alteration in gut microbiota, and contrariwise associations between CNS disorders and ENS. This paper further summarizes the synergetic relation between gastrointestinal and neuropsychological manifestations and emphasizes the need to include behavioral therapies in management plans.

Abstract
BACKGROUND AND AIM We investigated whether oral-dental conditions may be associated with the prevalence of irritable bowel syndrome (IBS) in a cross-sectional study in Japan. METHODS Information on lifestyle and abdominal symptoms was collected, and oral-dental examinations were performed from 2013 to 2017. To investigate the association between oral-dental conditions and IBS, this study used logistic regression analyses adjusted for relevant confounding factors, such as age, sex, BMI, stress, and eating between meals. RESULTS The prevalence of IBS was 484 (13.4%) among 3626 participants. The mean maximum occlusal force in the IBS group was significantly lower than that in the non-IBS group (0.306 ± 0.192 kN vs. 0.329 ± 0.205 kN, P = 0.014). The maximum occlusal force of the constipation-type IBS was significantly lower than that of other types of IBS without constipation type (0.269 ± 0.164 kN vs. 0.317 ± 0.198 kN, P = 0.010). Compared with those who had high values of maximum occlusal force (≧0.265 kN), those with a low value of maximum occlusal force (<0.265 kN) had a significantly greater risk for IBS (OR, 1.426; 95% CI, 1.135-1.792; P = 0.002), by multivariate analyses, across different categories of oral-dental condition in women, not in men. Women who had lowest third occlusal force (<0.206 kN) had approximately 35% significantly greater odds of having IBS compared with those who had highest third occlusal force (≧0.386 kN). CONCLUSIONS Results suggest that a reduction in the maximum occlusal force increases the risk of IBS in Japanese women.

Abstract
BACKGROUND Functional dyspepsia (FD) is characterized with multiple symptoms of indigestion and often accompanied with anxiety. However, there is currently an absence of effective treatment. Tandospirone is commonly used to treat generalized anxiety disorders. Whether tandospirone can improve the clinical symptoms of FD remain unknown. AIMS The present study was designed to explore the pharmacological effect of tandospirone on FD patient with anxiety, and the potential mechanisms were also elucidated. METHODS FD patients with anxiety were randomly divided into placebo and tandospirone treatment groups. Healthy volunteers were simultaneously recruited as control group. The gastrointestinal symptom score (GIS) and Hamilton anxiety scale (HAM-A) were performed before and after treatments with placebo or tandospirone. The serum levels of brain-derived neurotrophic factor (BDNF) and multiple inflammatory cytokines including tumor necrosis factor-α (TNF-α), and interleukin (IL)-6, IL-4, IL-1β, and IL-10 were determined. Regression analyses relating BDNF levels and gastrointestinal symptoms were performed. RESULTS Tandospirone significantly alleviated the gastrointestinal and anxiety symptoms of FD patient, as evidenced by reductions of GIS index and HAM-A scores. Compared with the healthy volunteers, FD patients had lower BDNF and IL-10 levels, but higher levels of IL-6 and TNF-α. Importantly, tandospirone increased serum BDNF and IL-10 and decreased IL-6 levels in FD patients. Relative analysis revealed that BDNF level was negatively associated with gastrointestinal symptoms in FD patients. CONCLUSION Tandospirone effectively improved both anxiety and gastrointestinal symptoms of patients with FD, and these therapeutic effects may be associated with the modulation of BDNF and inflammatory cytokines.

Abstract
BACKGROUND Due to complex pathophysiology of functional dyspepsia, medications to treat functional dyspepsia are not effective for all patients. Transcutaneous electrical acustimulation (TEA) is an potentially effective therapy for functional dyspepsia without proofs of definite mechanisms. AIMS We aimed to investigate the therapeutic impacts of TEA on postprandial distress syndrome (PDS) and explore potential neuroimmune mechanisms. METHODS We conducted a double-blinded, randomized, controlled trial in 30 PDS patients randomized for 4-week TEA or sham-TEA. Dyspeptic symptoms, gastric accommodation, gastric emptying and heart rate variability (HRV) were assessed. Duodenal mucosal inflammation was also evaluated. RESULTS The dyspeptic symptoms were improved with TEA compared with sham-TEA (P = 0.03). The initial satiety volume and the maximum tolerable volume (MTV) were both improved after the TEA treatment, compared with the sham-TEA group (P all < 0.05). The gastric emptying time (T1/2) was not altered with TEA or sham-TEA. The TEA treatment increased vagal activity and decreased sympathovagal ratio assessed by HRV (P all < 0.01). The IL-6 expression in bulb mucosa was downregulated by the TEA treatment compared to the baseline (P < 0.05). CONCLUSIONS Noninvasive TEA improves gastric accommodation and dyspeptic symptoms, possibly by downregulating the IL-6 expression in duodenal bulb mucosa via the vagal efferent pathway.

Neurogastroenterol Motil 2022; 34:e14378. [PMID: 35388579 DOI: 10.1111/nmo.14378] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2021] [Revised: 02/15/2022] [Accepted: 03/28/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND Low-grade duodenal inflammation has recently been identified in patients with functional dyspepsia (FD). Chemosensory tuft cells were reported to be associated with gastrointestinal diseases. We therefore assessed duodenal tuft cell density and microinflammation in patients with FD to determine whether these measures could serve as useful biomarkers, and also correlated tuft cell density and microinflammation in FD patients. METHODS Duodenal biopsy specimens were obtained from patients with FD and from controls. Tuft cells, eosinophils, and mast cells were immunochemically stained with specific antibodies. Tuft cells were identified by immunostaining for doublecortin-like kinase 1 (DCLK1); cholinergic tuft cells were assessed by double staining for choline acetyltransferase (ChAT) and DCLK1. Immune-type tuft cells were assessed by IL-25 mRNA expression using real-time PCR. KEY RESULTS The density of intramucosal eosinophils and mast cells was significantly higher in the duodenum of FD patients than in controls. The density of tuft cells was significantly higher in the duodenum of FD patients compared with controls, and significantly correlated with eosinophil density in the duodenum of FD patients and controls. Moreover, a fraction of ChAT-positive cells was DCLK1 positive; all duodenal DCLK1+ tuft cells were ChAT-immunoreactive in FD and in control subjects. CONCLUSIONS AND INFERENCES Cholinergic tuft cell density was higher in the duodenum of patients with FD and significantly correlated with eosinophil density. Further studies are needed to investigate the pathophysiological significance of tuft cells in FD and may provide valuable clues to the pathophysiology of FD.

Abstract
BACKGROUND Phosphodiesterase (PDE) inhibition has been reported to play a role in regulating gut motility, but the evidence is insufficient, and the mechanism remains unknown. The aim of this study was to investigate the possible role of phosphodiesterase-4 (PDE4) inhibitor rolipram in water avoidance stress-induced colonic hypermotility. METHODS A rat model of irritable bowel syndrome (IBS) with diarrhea (IBS-D) was established by water avoidance stress (WAS). Intestinal motility was assessed by fecal pellets expulsion per hour. The cyclic adenosine monophosphate (cAMP) and nitric oxide (NO) level in colon tissue were detected using ELISA assay and the Griess test, respectively. Western blotting was performed to assess the protein level of PDE, PKA/p-CREB, and neuronal nitric oxide synthase (nNOS) in the colon. To determine the role of rolipram in gut motility, the rats of the WAS + Rolipram and Rolipram group were injected with rolipram intraperitoneally. The colonic contractile activity was recorded with a RM6240 multichannel physiological signal system. KEY RESULTS WAS-induced gastrointestinal hypermotility and increased defecation in rats. After repeated stress, protein levels of PDE4 in the colon were promoted while PKA/p-CREB and nNOS were highly decreased. cAMP content in colon tissue did not change significantly. However, NO content decreased after WAS, and rolipram partly enhanced NO in WAS-exposed rats. In addition, intraperitoneal injection of rolipram partly inhibited the colonic motility in vivo. Meanwhile, we observed rolipram inhibited the contraction of colonic smooth muscle strips, and this inhibitory effect was abolished by Nω-Nitro-L-arginine (L-NNA), a nitric oxide synthase (NOS) inhibitor, tetrodotoxin (TTX), a blocker of neuronal voltage-dependent Na+ channels, Rp-Adenosine 3',5'-cyclic monophosphorothioate triethylammonium salt hydrate (Rp-cAMPS), an antagonist of cAMP. CONCLUSIONS AND INFERENCES Rolipram could relieve stress-induced gastrointestinal hypermotility. This effect may be partly through the cAMP-PKA-p-CREB pathway and NO pathway.

Abstract
Objective Functional Gastrointestinal Disorder (FGIDs) are a heterogenous group of disorders, with Irritable Bowel Syndrome (IBS) and Functional Dyspepsia (FD) being the most common disorders worldwide. The purpose of this study was to identify the spectra of FGIDs classified according to the ROME III criteria amongst an adult Pakistani population. It also aimed to correlate the psychosocial alarm symptoms with the prevalence of FGIDs and report the overlap of all FGID. Design This was a community based cross-sectional study. Multi-stage cluster sampling technique was applied, and 1062 households were initially randomly chosen using systematic sampling technique. Only one person from each household was enrolled in the study. After eligibility screening, 860 participating individuals were requested to fill out a structured ROME III interview questionnaire, administered to them by a trained interviewer. Results FGIDs were diagnosed in 468 individuals (54.4%), out of 860 participants. FD was found to be the most prevalent (70.2%), followed by Functional Heartburn (58.9%) and Functional bloating (56.6%). Amongst a total of 468 participants diagnosed with FGIDs, 347 (74.1%) had overlapping disorders. There was also a higher incidence of psychosocial alarm symptoms including higher pain severity (62.6% vs 46.4%) and being victimized at some point in their lives (26.1% vs 6.6%) amongst FGID patients. Conclusion There is a high disease burden of FGIDs in this study population, with approximately half of the population suffering from at least one type of FGID. Overlapping disorders are also common in this part of the world.

Abstract
Background/Aims Herbal medicine is an important complementary therapy for functional dyspepsia (FD). However, its effect against gastric hypersensitivity in patients with FD has rarely been evaluated. Yokukansan (YKS), a traditional Japanese herbal medicine, is effective against neuropathic and inflammatory pain. This study aims to use a maternal separation (MS) stress-induced FD model to investigate the effects of YKS against gastric hypersensitivity, gastric motility, and duodenal micro-inflammation. Methods The MS stress model was established by separating newborn Sprague-Dawley rats from their mothers for 2 hours a day from postnatal days 1 to 10. At the age of 7-8 weeks, the rats were treated with YKS at a dose of 5 mL/kg (1 g/kg) for 7 consecutive days. After YKS treatment, electromyographic activity in the acromiotrapezius muscle by gastric distention and the gastric-emptying rate were assessed. Immunohistochemical analysis of eosinophils in the duodenum and phosphorylated extracellular signal-regulated kinase (p-ERK) 1/2 in the spinal cord was performed. Results YKS treatment suppressed MS stress-induced gastric hypersensitivity and decreased the elevated levels of p-ERK1/2 in the spinal cord. In the gastroduodenal tract, YKS inhibited eosinophil-associated micro-inflammation but did not improve gastric dysmotility. Conclusions YKS treatment improved gastric hypersensitivity by alleviating eosinophil-associated micro-inflammation in the gastroduodenal tract. This treatment may be considered an effective therapeutic option for epigastric pain and micro-inflammation in patients with FD.

Abstract
Background The effects of psychological interventions on symptoms and psychology of functional dyspepsia (FD) remain unclear. We aimed to comprehensively evaluate the effects of psychological interventions on symptoms and psychology of FD. Methods We searched the PubMed, Cochrane Library, and Embase electronic databases for randomized controlled trials (RCTs) evaluating the role of psychological interventions in FD patients published before July 2021. Standardized mean differences (SMDs), risk ratios (RRs) and 95% confidence intervals (CIs) were calculated by a random effects model. Subgroup analyses and sensitivity analyses were also performed. Results Fourteen RCTs with a total of 1,434 FD patients were included. Compared with the control group, psychological interventions were significantly more likely to symptom improvement [RR = 1.74, 95% CI (1.12, 2.72), p = 0.01], relieve gastrointestinal symptoms scores at follow up [SMD = −1.06, 95% CI (−1.55, −0.57), p < 0.0001], relieve gastrointestinal symptoms scores at end of treatment [SMD = −0.98, 95% CI (−1.29, −0.67), p < 0.001], decrease anxiety [SMD = −0.8, 95% CI (−1.38, −0.22), p = 0.006] and depression levels [SMD = −1.11, 95% CI (−1.62, −0.61), p < 0.001]. The results of the subgroup analysis showed that psychotherapy was more likely to symptom improvement, relieve gastrointestinal symptoms scores and decreased depression levels compared to the control. Conclusions Psychological interventions may be effective in alleviating the symptoms and psychology of FD, but the effect appears to be limited to psychotherapy with fewer trials for other psychological interventions. More data from high-quality RCTs are needed to confirm their use in the treatment of FD.

Abstract
BACKGROUND Gastrointestinal (GI) symptoms are frequent complaints from individuals with nonalcoholic fatty liver disease (NAFLD). Dyspepsia is a universal clinical symptom and is among the most common GI complaints observed in the general population, but its prevalence in the population with NAFLD has not been previously investigated. OBJECTIVE To compare the prevalence of functional dyspepsia (FD) between patients with NAFLD and controls without liver disease. DESIGN AND SETTING Cross-sectional study at the Outpatient Liver Clinic, University Hospital, Belo Horizonte, Brazil. METHODS We included 96 NAFLD patients and 105 controls without liver disease. All participants were assessed for GI symptoms in accordance with the Rome III criteria. Evaluation methods included a questionnaire for FD (validated in Brazil), laboratory tests and upper GI endoscopy. RESULTS Mean age and sex were similar between the groups. The NAFLD group presented higher frequency of proton-pump inhibitor usage (31.3% vs 4.8%; P < 0.001) and prevalence of FD (25.0% versus 12.4%; P = 0.021). The symptom frequencies were as follows: postprandial distress, 22.9% versus 11.4% (P = 0.030); postprandial fullness, 18.8% versus 10.5% (P = 0.095); early satiation, 8.3% versus 5.7% (P = 0.466); and epigastric pain or burning, 18.8% versus 5.7% (P = 0.004), in NAFLD patients and controls, respectively. Multivariate analysis demonstrated that female sex (odds ratio, OR 6.97; 95% confidence interval, CI: 1.51-32.12; P = 0.013) and NAFLD diagnosis (OR 2.45; 95% CI: 1.14-5.27; P = 0.021) were independently associated with FD occurrence. CONCLUSION FD occurs more frequently in individuals with NAFLD than in controls without hepatic disease.

Abstract
BACKGROUND Potential etiological mechanisms of irritable bowel syndrome (IBS) have been reported, and emerging data suggest that immune activation is present in a major subset of IBS, especially in those with diarrhea. Intestinal mucosal mast cell and intraepithelial lymphocyte (IEL) infiltration and related factors were examined in patients with IBS. In addition, the correlations of symptoms and micro-inflammation were assessed. METHODS Intestinal biopsy specimens were obtained from patients with IBS and controls. Mast cells and IELs were stained with specific antibodies. The mRNA levels of cytokines and chemokines were assessed by quantitative reverse transcription polymerase chain reaction. RESULTS Infiltration of mast cells in the duodenum was significantly higher in IBS patients than in control subjects. The infiltration of IELs was higher in the duodenum and terminal ileum of IBS patients compared to the control subjects. The numbers of duodenal and ileal IELs were significantly correlated. The number of IELs but not mast cells in the duodenum and terminal ileum was significantly correlated with diarrhea frequency in control subjects and IBS patients. The expression level of the chemotactic chemokine CXCL11 was significantly higher in the duodenum of IBS patients. CONCLUSION Duodenal mast cells and IELs were increased in IBS patients. In addition, a positive correlation was found between the number of duodenal and ileal IELs and the frequency of diarrhea. Given that the present study was strictly observational, further studies are needed to clarify the pathophysiological functions associated with micro-inflammation in IBS.

Abstract
Living a healthy lifestyle is the most important need in the world today. However, oxidative stress (OS) is caused by several stress-inducing factors such as smoking, alcohol consumption, chronic diseases, and inflammatory responses, oxygen-free radicals are produced in excess and can damage major organs in the body. This phenomenon has been implicated in the pathogenesis of several gastrointestinal (GI) diseases, including gastritis, constipation, and inflammatory bowel diseases, which include Crohn’s disease, ulcerative colitis, functional dyspepsia, acid reflux, diverticular disease, and irritable bowel syndrome. In this review article, we provide a brief overview of the role of OS in the pathogenesis of GI disorders. Additionally, we discuss the therapeutic role of alkaline-reduced water (ARW) on GI diseases and existing studies on ARW related to GI diseases. Furthermore, we believe that findings from this review article will enhance the knowledge of the readers on the role of ARW on OS and inflammation-based GI diseases.

Abstract
Stress and anxiety contribute to the pathophysiology of irritable bowel syndrome (IBS), a female-predominant disorder of the gut-brain axis, characterized by abdominal pain due to heightened visceral sensitivity. In the current study, we aimed to evaluate in female rats whether epigenetic remodeling in the limbic brain, specifically in the central nucleus of the amygdala (CeA), is a contributing factor in stress-induced visceral hypersensitivity. Our results showed that 1 h exposure to water avoidance stress (WAS) for 7 consecutive days decreased histone acetylation at the GR promoter and increased histone acetylation at the CRH promoter in the CeA. Changes in histone acetylation were mediated by the histone deacetylase (HDAC) SIRT-6 and the histone acetyltransferase CBP, respectively. Administration of the HDAC inhibitor trichostatin A (TSA) into the CeA prevented stress-induced visceral hypersensitivity through blockade of SIRT-6 mediated histone acetylation at the GR promoter. In addition, HDAC inhibition within the CeA prevented stress-induced histone acetylation of the CRH promoter. Our results suggest that, in females, epigenetic modifications in the limbic brain regulating GR and CRH expression contribute to stress-induced visceral hypersensitivity and offer a potential explanation of how stress can trigger symptoms in IBS patients.

[PMID: 34404084 DOI: 10.14309/ajg.0000000000001397] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Accepted: 07/15/2021] [Indexed: 12/11/2022]
Abstract
INTRODUCTION Placebo response rates are relatively higher in clinical trials of disorders of brain-gut interaction. However, placebo response in functional dyspepsia (FD) has not been well described. Minimizing placebo response is important in drug development. We therefore conducted a meta-analysis to determine placebo response in trials for FD and to identify factors affecting placebo response rates. METHODS PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials were searched to identify double-blinded randomized controlled trials (RCTs) comparing medication with placebo in patients with FD. Both symptom improvement and complete relief were considered as separate primary endpoints in the analysis. Proportions of placebo patients experiencing any symptom improvement or complete relief were calculated. Dropouts after randomization for any reason were assumed to represent treatment failure for data extraction and analysis. Placebo response was pooled by a random-effects model, and effects of trial characteristics on the magnitude of placebo response were evaluated. RESULTS In 58 eligible placebo-controlled RCTs of FD from 52 selected citations, 6,732 of 17,890 participants in all trials received placebo. Pooled placebo response rates for symptom improvement and complete relief were 44.3% and 15.6%, respectively. The placebo response rate was lower when improvements were assessed for ≥8 weeks. Trials assessing complete symptom relief showed lower placebo response rates even in trials for <8 weeks. DISCUSSION Our systematic review and meta-analysis showed that pooled placebo response rates in double-blinded RCTs of FD depended on efficacy criteria. Trials assessing complete symptom relief showed stable low placebo response rates in short-term trials.

Abstract
Background/Aims Belching is the act of expelling gas from the stomach or esophagus noisily through the oral cavity. Although it is a physiological phenomenon, belching may also be a symptom of upper gastrointestinal diseases such as reflux esophagitis and functional dyspepsia (FD). A detailed epidemiology of belching has not yet been reported. The aim of this study is to examine the prevalence and clinical characteristics of clinically significant belching (CSB) in adults. Methods We analyzed 1998 subjects who visited the hospital for annual health checkups. Belching was evaluated by a simple question “Do you burp a lot?” and scored as 0 (never), 1 (occasionally), 2 (sometimes), 3 (often), or 4 (always). Subjects with CSB were defined as having scores ≥ 3. We also collected the clinical parameters, endoscopic findings, and data according to the Athens Insomnia Scale, Rome IV questionnaire, and Hospital Anxiety and Depression Scale (HADS). Results Of the 1998 subjects, 121 (6.1%) had CSB. Subjects with CSB had FD more commonly than reflux esophagitis, but presence of heartburn was high (10.7% vs 3.1%). In addition, the HADS and Athens Insomnia Scale scores in subjects with CSB were significantly higher than those in subjects without CSB. Presence of heartburn (OR, 2.07; 95% CI, 1.05-4.09), presence of FD (OR, 2.12; 95% CI, 1.33-3.36), anxiety/depression (OR, 2.29; 95% CI 1.51-3.45), and sleep disturbances (OR, 1.73; 95% CI, 1.14-2.61) were significantly associated with CSB. Conclusion The detailed epidemiology of belching in the general adult population was clarified.

Circuit-specific enteric glia regulate intestinal motor neurocircuits. Proc Natl Acad Sci U S A 2021; 118:2025938118.

Abstract
Glia in the central nervous system exert precise spatial and temporal regulation over neural circuitry on a synapse-specific basis, but it is unclear if peripheral glia share this exquisite capacity to sense and modulate circuit activity. In the enteric nervous system (ENS), glia control gastrointestinal motility through bidirectional communication with surrounding neurons. We combined glial chemogenetics with genetically encoded calcium indicators expressed in enteric neurons and glia to study network-level activity in the intact myenteric plexus of the proximal colon. Stimulation of neural fiber tracts projecting in aboral, oral, and circumferential directions activated distinct populations of enteric glia. The majority of glia responded to both oral and aboral stimulation and circumferential pathways, while smaller subpopulations were activated only by ascending and descending pathways. Cholinergic signaling functionally specifies glia to the descending circuitry, and this network plays an important role in repressing the activity of descending neural pathways, with some degree of cross-inhibition imposed upon the ascending pathway. Glial recruitment by purinergic signaling functions to enhance activity within ascending circuit pathways and constrain activity within descending networks. Pharmacological manipulation of glial purinergic and cholinergic signaling differentially altered neuronal responses in these circuits in a sex-dependent manner. Collectively, our findings establish that the balance between purinergic and cholinergic signaling may differentially control specific circuit activity through selective signaling between networks of enteric neurons and glia. Thus, enteric glia regulate the ENS circuitry in a network-specific manner, providing profound insights into the functional breadth and versatility of peripheral glia.

Abstract
BACKGROUND Little is known about possible underlying psychological abnormalities and physiology of reflux hypersensitivity (RH) as defined in the recent Rome IV classification. We aimed to assess markers of psychological comorbidity as well as gastro-esophageal reflux measurements in RH patients compared to controls and also in patients with functional heartburn (FH) and non-erosive reflux disease (NERD) versus controls. METHODS Data of 304 patients visiting our Functional Diagnostics Centre from 2016 to 2018 were analyzed. We focused on a psychological assessment using validated questionnaires (visceral sensitivity index; VSI, hospital anxiety and depression score; HADS) as well as multichannel intraluminal impedance (MII) and pH-metry data from the diagnostic work-up. KEY RESULTS We found a decreased VSI of 57.8 ± 15.4 points (pts) among RH patients (n = 45) indicating higher visceral sensitivity compared to 85.7 ± 2.0 pts in the control group (n = 31, P < 0.001). Furthermore, a significant difference in VSI was found between the FH (60.8 ± 23.3 pts, n = 59, P < 0.001) and between the NERD (61.9 ± 20.8 pts, n = 67, P < 0.001) both compared to the control group. The HADS also displayed a significant difference between the RH (11.9 ± 6.0 pts, P < 0.001), FH (11.0 ± 7.4 pts, P < 0.001), respectively, NERD (11.3 ± 8.9 pts, P < 0.001) as compared to the control group (2.0 ± 1.4 pts). CONCLUSIONS AND INFERENCES Increased sensation to visceral stimuli as well as anxiety and depression appears to play an important role not only in reflux hypersensitivity and functional heartburn as defined by Rome IV but also in NERD. These findings are in line with the disease concept of disorders of gut-brain interaction in which psychological comorbidities and visceral hypersensitivity play a major role.

Abstract
BACKGROUND The literature is limited regarding the prevalence of functional gastrointestinal disorders (FGIDs) in Central America, and the role of dietary factors. METHODS The Rome IV diagnostic questionnaire and National Cancer Institute Diet History questionnaire were administered in one-on-one interviews to a distributed cross section of the general adult population of Western Honduras. Our aim was to estimate prevalence of common FGIDs and symptoms and their relationships to dietary habits. RESULTS In total, 815 subjects were interviewed, of whom 151 fulfilled criteria for an FGID (18.5%). Gastroduodenal FGIDs were noted in 9.4%, with epigastric pain syndrome (EPS) more common than postprandial distress syndrome, 8.5% versus 1.6%. Among bowel disorders, functional abdominal bloating (FAB) was most prevalent (6.3%), followed by irritable bowel syndrome (3.6%), functional diarrhea (FDr; 3.4%), and functional constipation (1.1%). A significant inverse association was noted between regular bean intake and any FGID (OR 0.41, 95% CI 0.27-0.63), driven by IBS and FDr. Vegetable consumption was associated with lower prevalence of functional diarrhea (OR 0.12; 95% CI 0.04-0.35) and any diarrheal disorder (OR 0.11; 95% CI 0.04-0.31). Subjects with a median daily intake of ≥ 4 corn tortillas had 1.75 (95% CI 1.22-2.50) times the odds of having any FGID. CONCLUSIONS FGIDs were common in this rural low-resource setting in Central America, with an intriguing distribution of specific FGIDs. EPS and FAB were common, but IBS was not. Local dietary factors were associated with specific FGIDs, suggesting that diet may play a role in global variations of FGIDs.

Abstract
BACKGROUND Functional dyspepsia (FD) is a common upper gastrointestinal disorder, but the current treatments are still unsatisfactory. Fingerroot (Boesenbergia rotunda [L.] Mansf.; BR) is used as a traditional medicine for dyspepsia despite a lack of proven evidence. OBJECTIVE This study aimed to evaluate the efficacy and safety of BR extract in the treatment of patients with FD. METHODS In a randomized, double-blinded, placebo-controlled trial, 160 patients with FD based on Rome IV criteria were to be recruited and randomly assigned (1:1 ratio) to receive BR (350 mg extract powder) or placebo 3 times daily for 4 weeks. Primary end point was change in the summed total score of Short-Form Leeds Dyspepsia Questionnaire. Secondary end points were the rate of symptom relief, the reduction of blood inflammatory markers and the improvement in gastric histology according to the Updated Sydney System. RESULTS One hundred sixty patients (62 [38.8%] men, aged 56.9 ± 14.8 years) were randomized to the BR group (n = 80) and placebo group (n = 80), and 138 patients completed this study. Overall symptom improvement was significantly greater in the BR group than in the placebo group (-7.1 ± 2.0 vs. -3.7 ± 0.8, repeated measures ANOVA, p < 0.05). Total symptom scores significantly improved with decrease in blood inflammatory markers in the BR group compared with the placebo group (p < 0.05). Proportion of responders was higher in the BR group (58%) than in the placebo group (34.6%) according to the intention-to-treat analysis (p < 0.05) with the number needed to treat calculated as 4.3. No difference in gastric histology was observed in both groups. BR extract was well tolerated with few adverse events. These effects were associated with acute phase reactants reduction. CONCLUSIONS BR extract represents an effective and safe alternative to manage dyspepsia symptoms in FD patients.

Abstract
Aim. Evaluation of the practice of using trimebutine (tablets, 300 mg, extended release), for the treatment of patients with functional gastrointestinal disorders (FGID) in primary health care.
Materials and methods. A prospective observational multicenter non-interventional study was carried out, which included patients of both sexes aged 18 to 60 years with a verified diagnosis of functional gastrointestinal disorders (functional dyspepsia, irritable bowel syndrome, biliary tract dysfunction, sphincter of Oddi dysfunction, postcholecystectomy syndrome). Trimebutine was prescribed in accordance with the instructions for medical use: orally, 300 mg twice per day for 28 days. The severity of simptoms was evaluated by five-point rating scale.
Results. The study included 4433 patients, the per protocol sample consisted of 3831 people. The proportion of patients with a significant decrease in the severity of abdominal pain after treatment was 74.73% (95% confidence interval CI 73.3276.11). At the and of the study a statistically significant decrease in the severity of FGID` simptoms was observed: epigastric pain/burning (mean score at the 1st visit was 1.21 [95% CI 1.181.25], at the 2nd visit 0.22 [95% CI 0.20.23]; p0.001), abdominal pain (1st visit 2.01 [95% CI 1.982.04), 2nd visit 0.33 [95% CI 0.310.35]; p0.001), biliary pain (1st visit 1.22 [95% CI 1.181.26], 2nd visit 0.2 [95% CI 0.190.22]; p0.001), postprandial fullness and early satiation (1st visit 1.29 [95% CI 1.251.32], 2nd visit 0.21 [95% CI 0.190.22]; p0.001), severity of heartburn (1st visit 0.92 [95% CI 0.880.95], 2nd visit 0.18 [95% CI 0.170.20]; p0.001), belching (1st visit 1.13 [95% CI 1.091.16], 2nd visit 0.22 [95% CI 0.210.24]; p0.001), as well as abdominal distention (1st visit 1.99 (95% CI 1, 96, 2.03), 2nd visit 0.43 [95% CI 0.410.45]; p0.001).
Conclusion. The present prospective observational multicenter non-interventional study has demonstrated that trimebutine is an effective approach to treating FGID.

Abstract
BACKGROUND AND AIM Functional gastrointestinal disorders (FGIDs) are frequently overlapped. The present study was designed to (i) search the clinical differences between patients with single FGID and overlap FGIDs and (ii) define the most common FGIDs associations to identify homogenous subgroups of patients. METHODS A total of 3555 outpatients with FGID filled out the Rome III adult diagnostic questionnaire, Bristol stool form, and four 10-point Likert scales to report the severity of constipation, diarrhea, bloating, and abdominal pain. An unsupervised algorithm was used to estimate the number of groups directly from the data. A classification tree separated patients into different subgroups, according to FGIDs. Multinomial logistic regression was used to characterize the groups of patients with overlap disorders. RESULTS Patients reported 3.3 ± 1.9 FGIDs (range 1-10, median = 3); 736 reported only one FGID, while 2819 reported more than one FGID (3.8 ± 1.7). Patients with single FGID had higher body mass index (P < 0.001), never report irritable bowel syndrome (IBS), and rarely report fecal incontinence and anorectal pain (< 1% for each disorder). The non-supervised clustering of the 2819 patients with overlap FGIDs divided this population into 23 groups, including five groups associated with only one disorder (IBS-diarrhea, dysphagia, functional constipation, levator ani syndrome, and IBS-unspecified). Ten groups were related to two overlap disorders and eight groups to three or more disorders. Three disorders were not explicitly associated with a given group: IBS-mixed, proctalgia fugax, and nonspecific anorectal pain. CONCLUSION Patients with FGID mostly report overlap disorders in a limited number of associations, each significantly associated with a few disorders.

Abstract
Visceral pain refers to pain arising from the internal organs and is distinctly different from the expression and mechanisms of somatic pain. Diseases and disorders with increased visceral pain are associated with significantly reduced quality of life and incur large financial costs due to medical visits and lost work productivity. In spite of the notable burden of illness associated with those disorders involving increased visceral pain, and some knowledge regarding etiology, few successful therapeutics have emerged, and thus increased attention to animal models of visceral hypersensitivity is warranted in order to elucidate new treatment opportunities. Altered microbiota-gut-brain (MGB) axis communication is central to the comorbid gastrointestinal/psychiatric diseases of which increased visceral (intestinal) sensitivity is a hallmark. This has led to a particular focus on intestinal microbiome disruption and its potential role in the etiology of heightened visceral pain. Here we provide a review of studies examining models of heightened visceral pain due to altered bidirectional communication of the MGB axis, many of which are conducted on a background of stress exposure. We discuss work in which the intestinal microbiota has either been directly manipulated (as with germ-free, antibiotic, and fecal microbial transplantation studies) or indirectly affected through early life or adult stress, inflammation, and infection. Animal models of visceral pain alterations with accompanying changes to the intestinal microbiome have the highest face and construct validity to the human condition and are the focus of the current review.

Lee KJ. The Usefulness of Symptom-based Subtypes of Functional Dyspepsia for Predicting Underlying Pathophysiologic Mechanisms and Choosing Appropriate Therapeutic Agents. J Neurogastroenterol Motil 2021; 27:326-336.

Abstract
Functional dyspepsia (FD) is considered to be a heterogeneous disorder with different pathophysiological mechanisms or pathogenetic factors. In addition to traditional mechanisms, novel concepts regarding pathophysiologic mechanisms of FD have been proposed. Candidates of therapeutic agents based on novel concepts have also been suggested. FD is a symptom complex and currently diagnosed by symptom-based Rome criteria. In the Rome criteria, symptom-based subtypes of FD including postprandial distress syndrome and epigastric pain syndrome are recommended to be used, based on the assumption that each subtype is more homogenous in terms of underlying pathophysiologic mechanisms than FD as a whole. In this review, the usefulness of symptombased subtypes of FD for predicting underlying pathophysiologic mechanisms and choosing appropriate therapeutic agents was evaluated. Although several classic pathophysiologic mechanisms are suggested to be associated with individual dyspeptic symptoms, symptom-based subtypes of FD are not specific for a certain pathogenetic factor or pathophysiologic mechanism, and may be frequently associated with multiple pathophysiologic abnormalities. Novel concepts on the pathophysiology of FD show complex interactions between pathophysiologic mechanisms and pathogenetic factors, and prediction of underlying mechanisms of individual patients simply by the symptom pattern or symptom-based subtypes may not be accurate in a considerable proportion of cases. Therefore, subtyping by the Rome criteria appears to have limited value to guide therapeutic strategy, suggesting that the addition of objective parameters or subclassification reflecting physiologic or pathologic tests may be necessary for the targeted therapeutic approaches, particularly when therapeutic agents targeting novel mechanisms are available.

Abstract
BACKGROUND AND AIM Functional gastrointestinal disorders are a group of stress-sensitive gut-brain disorders. The COVID-19 outbreak has caused immense stress and anxiety among the general public. Strict measures to counter COVID-19 emergency, including physical distancing, have also taken a toll on physical and mental health. We investigated the impact of the COVID-19 pandemic on the gastrointestinal and psychological symptoms of functional dyspepsia (FD) and irritable bowel syndrome (IBS). METHODS An online survey was conducted in Japan for a group of randomly assigned panelists from May 26 to 27, 2020. Each respondent answered a questionnaire on stress, physical distancing, and worries about COVID-19. Gastrointestinal symptoms were assessed to diagnose FD and IBS (Rome III), and psychological symptoms were assessed using the Hospital Anxiety and Depression Scale. RESULTS A total of 5157 subjects were finally enrolled, with FD in 8.5%, IBS in 16.6%, and FD-IBS overlap in 4.0%. For both gastrointestinal and psychological symptoms, respondents with FD-IBS overlap showed the worst scores, followed by IBS-alone, then FD-alone respondents. During the COVID-19 pandemic, 11.9% of respondents reported deterioration and 2.8% reported improvement of gastrointestinal symptoms. FD-IBS overlap, psychological disease comorbidity, and stress at work/school were significantly associated with symptom deterioration. Younger age, commuting by public transport, and work/study from home were associated with symptom improvement. CONCLUSIONS The COVID-19 pandemic negatively affected FD/IBS subjects, with respondents showing FD-IBS overlap syndrome as the most important independent factor associated with deterioration in gastrointestinal symptoms. Physicians need to take extra care of FD/IBS patients in the post-COVID period.

Abstract
Background In dyspeptic patients with Helicobacter pylori contributes to non-alcoholic fatty liver disease. However, little evidence available from Pakistan. Objective The study aims to determine the frequency and risk factors of non-alcoholic fatty liver disease in dyspeptic patients with Helicobacter pylori. Methods This cross-sectional study was conducted between 22 November 2016 and 30 June 2018. Adults of age between 18 and 90 years who attended the out-patient department due to abdominal discomfort, pain, fullness, and bloating who underwent upper gastrointestinal tract endoscopy were enrolled after taking informed consent. Patients with celiac disease, inflammatory bowel disease, taking alcohol, pregnant women and lactating mothers, known cases of hepatitis B and C, and history of recent antibiotic use were excluded. Data on age, gender, smoking, alcohol use, dyslipidemia, hypertension, type 2 diabetes mellitus, and ischemic heart disease were collected. Non-alcoholic fatty liver disease was diagnosed through ultrasonography. Helicobacter pylori infection was detected using a carbon urea breath test. Results A total of 698 patients were screened for eligibility, and 399 (57.2%) had Helicobacter pylori infection and were enrolled in the study after consent. The median age was 50.1 (interquartile range = 14.5) years and 209 (52.4%) were males. Frequency of non-alcoholic fatty liver disease in patients with Helicobacter pylori dyspeptic patients was 153 (38.3%). Factors associated with non-alcoholic fatty liver disease in the presence of Helicobacter pylori were dyslipidemia 7.38 (95% confidence interval = 2.4-22.71), type 2 diabetes mellitus 5.96 (95% confidence interval = 1.86-19.07), hypertension 3.0 (95% confidence interval = 1.21-7.45), and moderate gastritis 2.81 (95% confidence interval = 1.2-6.59). Conclusion The frequency of non-alcoholic fatty liver disease in Helicobacter Pylori dyspeptic patients was 38.3%. Male gender, dyslipidemia, hypertension, ischemic heart disease, and moderate gastritis were associated with non-alcoholic fatty liver disease.

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: Functional dyspepsia (FD) has rarely been investigated in areas with a high prevalence of esophageal squamous cell carcinoma (ESCC). This study aims to reveal the epidemiological and clinical features of FD and organic dyspepsia (OD) in such a population. Methods: A middle-aged and elderly population-based study was conducted in a region with a high incidence of ESCC. All participants completed the Gastroesophageal Reflux Disease Questionnaire and Functional Gastrointestinal Disease Rome III Diagnostic Questionnaire, and they underwent gastroscopy. After exclusion of gastroesophageal reflux disease, uninvestigated dyspepsia (UID) was divided into OD and FD for further analyses. Results: A total of 2916 participants were enrolled from July 2013 to March 2014 in China. We detected 166 UID cases with questionnaires, in which 17 patients with OD and 149 with FD were diagnosed via gastroscopy. OD cases presented as reflux esophagitis (RE), ESCC, and duodenal ulcer. Heartburn (52.94%) and reflux (29.41%) were common in OD, but no symptomatic differences were found between FD and OD. Male sex, low education level, and liquid food were the risk factors for OD, while frequent fresh vegetable consumption was a protective factor. FD included 56 (37.58%) cases of postprandial distress syndrome (PDS), 52 (34.89%) of epigastric pain syndrome (EPS), nine (6.04%) of PDS + EPS, and 32 (21.48%) of FD + functional esophageal disorders. The Helicobacter pylori infection rate in FD patients was not higher than that in the control group (34.23% vs. 42.26%, P = 0.240). Frequent spicy food consumption was associated with PDS (odds ratio [OR]: 2.088, 95% confidence interval [CI]: 1.028–4.243), while consumption of deep well water was protective for PDS (OR: 0.431, 95% CI: 0.251–0.741). Conclusions: The prevalence of FD was 5.11% in the studied population. Gastroscopy should be prescribed for dyspepsia patients in case that ESCC and RE would be missed in UID cases diagnosed solely by the Rome III questionnaire.

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 AND AIM Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorders, and bile acids are thought to be associated with the pathogenesis of IBS. Bile acid receptors are expressed on intestinal epithelial cells. However, no study has assessed bile acid receptor proteins in IBS. Therefore, we examined the intestinal mucosal expression of bile acid receptors in patients with IBS. METHODS Intestinal biopsies were performed in patients with IBS and controls. Mast cells, vitamin D receptor (VDR), and somatostatin were stained with specific antibodies. Levels of VDR, farnesoid X receptor (FXR), takeda-G-protein-receptor-5 (TGR5), claudins, and transient-receptor-potential-cation-channel-subfamily-V-member 6 (TRPV6) were assessed by western blotting. RESULTS 3Mast cell counts in the second part of the duodenum were significantly higher in patients with IBS than in controls. VDR protein levels were significantly elevated in the duodenum and terminal ileum of patients with IBS compared with controls, although this difference was not seen in the cecum or rectum. FXR and TGR5 protein levels did not differ in any part of the intestine. VDR-positive cryptal epithelia in IBS were distributed not only at basal crypt but also along the upper part of the basal crypt epithelial cells. In contrast, the pattern of gut somatostatin-positive cells, claudins, and TRPV6 levels did not differ. CONCLUSIONS The number of mast cells in the duodenum was significantly increased, and the protein expression levels of VDR, but not those of FXR or TGR5, were elevated in the duodenal epithelial crypt in patients with IBS.

Abstract
OBJECTIVE To explore the differences in frequency and epidemiology of functional gastrointestinal disorders (FGIDs) in a primary care setting, and to examine the health-related quality of life (HRQOL) and healthcare utilization of FGID patients based on the Rome III and Rome IV criteria. METHODS A cross-sectional study of consecutive adults in a primary healthcare setting was conducted. Differences in epidemiology, and HRQOL of common FGIDs (functional dyspepsia [FD], irritable bowel syndrome [IBS], functional diarrhea, functional constipation [FC]) between the Rome III and IV criteria were explored. RESULTS Among a total of 1002 subjects recruited, the frequency of common FGIDs was 20.7% and 20.9% among subjects based on the Rome III and Rome IV criteria, respectively. The frequency of IBS reduced from 4.0% (Rome III) to 0.8% (Rome IV), while that of functional diarrhea increased from 1.2% (Rome III) to 3.3% (Rome IV). In contrast, there was no significant change in the frequency of FD (7.5% [Rome III] vs 7.6% [Rome IV]) and FC (10.5% [Rome III] vs 11.7% [Rome IV]). Most of the Rome III IBS subjects (52.5%, n = 21) who did not meet Rome IV IBS criteria, fulfilled the criteria for FC, functional diarrhea, FD, or overlap syndrome. Subjects with all FGIDs, regardless of criteria, had more healthcare utilization and lower HRQOL compared to non-FGID controls. CONCLUSIONS The Rome IV criteria alter the frequency of IBS and functional diarrhea, but not FD and FC, when compared to the Rome III criteria. Regardless of criteria, FGIDs had a significant impact on healthcare burden and HRQOL.

Abstract
Gastric hypersensitivity is a major pathophysiological feature of functional dyspepsia (FD). Recent clinical studies have shown that a large number of patients with FD present with gastroduodenal microinflammation, which may be involved in the pathophysiology of FD. However, no animal model reflecting this clinical characteristic has been established. The underlying mechanism between microinflammation and FD remains unknown. In this study, using a maternal separation (MS)-induced FD model, we aimed to reproduce the gastroduodenal microinflammation and reveal the interaction between gastroduodenal microinflammation and gastric hypersensitivity. The MS model was established by separating newborn Sprague-Dawley rats for 2 h a day from postnatal day 1 to day 10. At 7-8 wk of age, electromyography was used to determine the visceromotor response to gastric distention (GD) and immunohistochemistry was performed to detect distension-associated neuronal activation as well as immunohistological changes. Our results demonstrated that MS-induced FD rats underwent gastric hypersensitivity with GD at 60 and 80 mmHg, which are related to increased p-ERK1/2 expression in the dorsal horn of T9-T10 spinal cords. Eosinophils, but not mast cells, were significantly increased in the gastroduodenal tract, and the coexpression rate of CD11b and major basic protein significantly increased in MS rats. Treatment with dexamethasone reversed gastric hypersensitivity in MS-induced FD rats by inhibiting eosinophil infiltration. These findings indicated that neonatal MS stress induces eosinophil-associated gastroduodenal microinflammation and gastric hypersensitivity in adulthood in rats. Microinflammation contributes to gastric hypersensitivity; therefore, anti-inflammatory therapy may be effective in treating patients with FD with gastroduodenal microinflammation.NEW & NOTEWORTHY We showed for the first time that neonatal MS stress-induced FD rats undergo gastroduodenal eosinophil-associated microinflammation in adulthood. Suppression of microinflammation attenuated gastric hypersensitivity in MS rats. These findings established a functional link between microinflammation and gastric hypersensitivity, which may provide a potential clue for the clinical treatment of FD.

Abstract
Background/Aims Gastroparesis is identified as a subject that is understudied in Asia. The scientific committee of the Asian Neurogastroenterology and Motility Association performed a Knowledge, Attitude, and Practices survey on gastroparesis among doctors in Asia. Methods The questionnaire was created and developed through a literature review of current gastroparesis works of literature by the scientific committee of Asian Neurogastroenterology and Motility Association. Results A total of 490 doctors from across Asia (including Bangladesh, China, Hong Kong, Indonesia, Japan, Malaysia, Myanmar, the Philippines, Singapore, South Korea, Taiwan, Thailand, and Vietnam) participated in the survey. Gastroparesis is a significant gastrointestinal condition. However, a substantial proportion of respondents was unable to give the correct definition and accurate diagnostic test. The main reason for lack of interest in diagnosing gastroparesis was "the lack of reliable diagnostic tests" (46.8%) or "a lack of effective treatment" (41.5%). Only 41.7% of respondents had access to gastric emptying scintigraphy. Most doctors had never diagnosed gastroparesis at all (25.2%) or diagnosed fewer than 5 patients a year (52.1%). Conclusions Gastroparesis can be challenging to diagnose due to the lack of instrument, standardized method, and paucity of research data on normative value, risk factors, and treatment studies in Asian patients. Future strategies should concentrate on how to disseminate the latest knowledge of gastroparesis in Asia. In particular, there is an urgent need to estimate the magnitude of the problems in high risk and idiopathic patients as well as a standardized diagnostic procedure in Asia.

[PMID: 33497382 PMCID: PMC7837482 DOI: 10.1371/journal.pone.0245511] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Accepted: 12/30/2020] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND AND AIM The association between body mass index (BMI) and functional gastrointestinal disorders (FGIDs) has been inconsistent. We aimed to explore the association of BMI with FGIDs in a primary care setting to provide more data in this area. METHODS A cross-sectional study of consecutive Asian adults attending a primary healthcare setting was conducted. This study was conducted in 2 phases: The association between BMI and common FGIDs (functional diarrhea/FD, irritable bowel syndrome/IBS, functional diarrhea and functional constipation/FC) was studied initially. The influence of anxiety and depression on BMI and FGIDs was additionally explored in phase 2. RESULTS A total of 1002 subjects (median age 32 years, 65.4% females, 90.7% Malay ethnicity, 73.2% higher than secondary level education) were recruited between August 2019 to January 2020. The majority of subjects were obese (39.2%), and had central obesity (51.7%), while 6.1% had metabolic syndrome. The prevalence of FD, IBS, functional diarrhea and FC were 7.5% (n = 75), 4.0% (n = 40), 1.2% (n = 12) and 10.5% (n = 105) respectively, based on the Rome III criteria. Among individual FGIDs, FD subjects had more underweight adults (BMI<18.5kg/m2) compared to controls (13.3% vs 3.5%, P = 0.002) and being underweight remained as an independent association with FD [OR = 3.648 (95%CI 1.494-8.905), P = 0.004] at multi-variate analysis. There were no independent associations between BMI and other FGIDs. When psychological morbidity was additionally explored, anxiety (OR 2.032; 95%CI = 1.034-3.991, p = 0.040), but not depression, and a BMI<18.5kg/m2 (OR 3.231; 95%CI = 1.066-9.796, p = 0.038) were found to be independently associated with FD. CONCLUSIONS FD, but not other FGIDs, is associated with being underweight. This association is independent of the presence of anxiety.

Abstract
Objective The aim of this study was to detect the expression of interleukin (IL)-1β and transforming growth factor (TGF)-β1 in the colonic tissue and serum of irritable bowel syndrome (IBS) rats, as well as the distribution and expression of corticotropin-releasing factor (CRF) in the spinal cord and brain of the visceral hypersensitivity rats, thus to ascertain the mechanism of visceral hypersensitivity signal conduction pathway. Methods The expression of IL-1β and TGF-β1 in the colonic tissue and serum of IBS rats was screened by the liquid chip technology and verified by RT-PCR technology. Then the quantitative analysis of CRF in the spinal cord and brain was achieved by the immunohistochemical method and computerized image system. Result The rat model with visceral hypersensitivity was successfully established. Among the screened indicators of IL-1β and TGF-β1 in colon tissue and serum, only the expression of IL-1β in the model group was up-regulated (P < 0.05). The immunohistochemical method showed that CRF was expressed in the spinal cord, hypothalamus, and the third ventricle. The positive index number of the model groups was higher than that of the control group (P < 0.01). Conclusion From the research, it can be inferred that IL-1β may participate in the pathogenesis mechanism of IBS via regulating the colon function. The increasing expression of CRF linked to stress in the spinal cord, hypothalamus and the third ventricle indicated that it might play an important role in the mechanisms of visceral hypersensitivity signal conduction pathway.

Therap Adv Gastroenterol 2020; 13:1756284820977402. [PMID: 33343707 PMCID: PMC7727037 DOI: 10.1177/1756284820977402] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Accepted: 11/09/2020] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Fibromyalgia and functional gastrointestinal disorders (FGID) including irritable bowel syndrome (IBS) are common conditions presenting in clinical settings and are more prevalent in women. While the relationship between IBS and fibromyalgia has been demonstrated, a review of the prevalence of the broader group of FGID in adults with fibromyalgia has not been undertaken. The aim of this review was to systematically review the published literature, identifying the comorbidity of FGID in people with fibromyalgia, and to discuss the clinical implications, limitations of current research and areas of interest for future research. METHODS Medline, Embase, CINAHL and Web of Science were searched during June 2019. Results were screened for original research articles meeting established criteria for identification of FGID in adults diagnosed with fibromyalgia. RESULTS A total of 14 studies involving 1340 adults with fibromyalgia, 363 healthy controls and 441 adults with other pathologies were included in this review. Only 1 of the 14 studies included surveyed the full range of FGID . Functional gut disorders were matched to Rome II criteria for reporting and comparison. In addition to increased abdominal pain and functional bloating or gas, IBS of mixed-pattern and constipation-types appear to be more prevalent than diarrhoea-predominant IBS in adults with fibromyalgia. CONCLUSION This review confirms previous reports that IBS is common in people living with fibromyalgia and suggests that IBS-mixed and constipation types predominate. An association with a range of FGID other than IBS is suggested, but data are limited. Research exploring the association between fibromyalgia and functional gastrointestinal dysfunction beyond IBS are warranted.

Abstract
BACKGROUND Functional dyspepsia (FD) is one of the most common functional gastrointestinal disorders (FGIDs) and significantly influences patients' quality of life. Many studies have found that patients with FD show significant functional abnormalities in multiple brain regions. However, these functional cerebral abnormalities are not fully consistent. This protocol aims to qualitatively and quantitatively assess and synthesize the functional cerebral abnormalities found in FD. METHODS A systematic search will be conducted in 4 electronic databases (Medline, Web of Science, EMBASE, and the Cochrane Library) from inception to June 30, 2019, with the language restricted to English. Study selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Quality assessment will be performed with a custom 11-point checklist. The functional changes in brain regions and the correlations between these altered brain regions and clinical variables in patients with FD will be evaluated through qualitative review. If data are available, an Anisotropic Effect Size version of Signed Differential Mapping (AES-SDM) will be used to synthesize the brain functional alterations and clinical variables in patients with FD. RESULTS This review and meta-analysis will qualitatively and quantitatively assess and synthesize functional cerebral abnormalities consistently found in FD. CONCLUSION This may assist in mapping functional brain abnormalities to characterize imaging-based neural markers of FD and improve our knowledge of the pathogenesis of FD.

Expectations of IBS patients concerning disease and healthcare providers: Results of a prospective survey among members of a French patients' association. Clin Res Hepatol Gastroenterol 2020; 44:961-967. [PMID: 32205115 DOI: 10.1016/j.clinre.2020.02.014] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2019] [Revised: 02/06/2020] [Accepted: 02/17/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND AND AIMS IBS patients have an impaired quality of life (QoL) and feel dissatisfaction with medical care. We aim to describe the expectations of members of the French Association of IBS patients (APSSII) concerning health care providers (HCPs) and a patients' organization. PATIENTS AND METHODS From January to June 2013, APSSII members were asked to answer questionnaires on their expectations and experiences concerning IBS and HCP. RESULTS 222/330 (67%) responded (women: 68.5%, 46.5±17.7 years, disease duration: 8.8±0.7 years, IBS-D 33.6%, IBS-C 26.7%, IBS-M 38.2%. IBS-SSS>300 in 53% and HAD score>19 in 45%). QoL impairment was correlated with disease severity and HAD score (r=-0.707 and r=-0.484, P<0.001 respectively), but not with IBS subtype. Expectations for IBS were "improved health", "better information on causes and treatments" (94%) and "better disease recognition" (86%). A significant gap was observed between expectations and experiences with HCPs. Better information, less isolation, recognition of the disease and a decrease in medical expenses were the main expectations for joining a patients' organization. CONCLUSIONS French IBS patients have a severe disease with a significant psychological impact and impaired QoL in half of the patients, certain unsatisfied expectations concerning HCP and high expectations in joining a patients' organization.

Abstract
Objective: Moxibustion (MOX) is used to treat a wide variety of disorders, including those with gastric symptoms. However, the exact mechanisms underlying the beneficial effects of MOX are unknown. The purpose of this study was to investigate if application of indirect MOX (iMOX) to ST 36 reduces restraint stress (RS)-induced alteration in gastric responses of conscious rats, and if a somatoautonomic reflex mediates gastric emptying (GE). Materials and Methods: One group of rats was fed solid food after 24 hours of fasting. Immediately after food ingestion. These rats were subjected to RS. Ninety minutes after feeding, the rats were euthanized, and their gastric contents were removed to calculate GE. iMOX had been performed at ST 36 bilaterally throughout the stress loading. To investigate if vagal-nerve activity was involved in mediating the stress-induced alterations of GE by iMOX, atropine was intraperitoneally administered to other rats just before initiating RS; bilateral truncal vagotomy had been performed on day 14 before GE measurement. Results: RS delayed GE significantly (42.9 ± 5.8%)in stressed rats, compared to nonstressed rats (68.7 ± 1.8%). iMOX at ST 36 reduced stress-induced inhibition of GE significantly (67.1 ± 2.4%). MOX-mediated reduction of GE disappeared upon atropine injection and vagotomy. Conclusions: RS-induced delayed GE may be ameliorated by iMOX at ST 36. Somatoautonomic, reflex-induced vagal-nerve activity helps mediate the stimulatory effects of iMOX on RS-induced delayed GE. As a complementary and alternative medicine, iMOX may also be advantageous for patients with gastric disorders, such as functional dyspepsia.

Evaluation of the effects of Bidens tripartita extracts and their main constituents on intestinal motility - An ex vivo study. JOURNAL OF ETHNOPHARMACOLOGY 2020; 259:112982. [PMID: 32442590 DOI: 10.1016/j.jep.2020.112982] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Revised: 05/06/2020] [Accepted: 05/14/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Based on traditional medicine, infusions of Bidens species (Asteraceae) have been successfully used in the treatment of acute and chronic enteritis. Additionally, ethnopharmacological reports demonstrating the gastrointestinal, gastroprotective, anti-inflammatory, antiulcerogenic and immunomodulatory potency of Bidens tripartita Linn. (Asteraceae) and its constituents make the plant a particularly interesting herbal drug candidate for the supportive treatment of functional gastrointestinal and motility disorders. AIM OF THE STUDY The study aimed to verify the effects of B. tripartita and its main flavonoid constituents on intestinal contractility patterns under ex vivo conditions. MATERIALS AND METHODS The effects of B. tripartita preparations and their main flavonoids were identified using an alternative model of porcine isolated jejunum specimens. Using LC-ESI-MS, the effects of six different standardized extracts, aqueous (BT1), methanolic 50% (BT2), methanolic (BT3), diethyl ether (BT4), ethyl acetate (BT5) and butanol (BT6) (0.001-0.1 mg/mL), as well as three pure isolated flavonoids, luteolin (LUT), cynaroside (CYN) and flavanomarein (ION) (0.001-100 μM), were evaluated towards spontaneous and acetylcholine-induced motility. RESULTS AND CONCLUSION s: The results showed the potent prokinetic effects of the B. tripartita extracts and their flavonoids on jejunum smooth muscle. The myocontractile effect was observed on both spontaneous and acetylcholine-induced contractility. There were no substantial differences in the magnitude of myocontractile effects between all six extracts with the exception of the butanol extract which seemed to have a slightly stronger prokinetic effect than the other extracts. The use of extracts at the highest tested concentrations provoked an approximately 1.5-fold increased reaction to acetylcholine compared to the control treatment. The myocontractile effect of the single flavonoids justifies the hypothesis that these secondary metabolites are responsible for the prokinetic activity of all the tested extracts. Among the tested flavonoids, CYN appeared to be the most potent ingredient of B. tripartita; the increase in the response to acetylcholine in the presence of this compound exceeded 250% of the control reaction. In view of the obtained results, the range of functional gastrointestinal disorders in which B. tripartita could be expected to bring benefits include the predominantly constipative phases of irritable bowel syndrome and dyspeptic complaints in which treatment protocols usually involve gastroprokinetics.

Abstract
OBJECTIVE To determine the prevalence of functional dyspepsia (FD) and irritable bowel syndrome (IBS) in patients eligible for cholecystectomy and to investigate the association between presence of FD/IBS and resolution of biliary colic and a pain-free state. SUMMARY BACKGROUND DATA More than 30% of patients with symptomatic cholecystolithiasis reports persisting pain post-cholecystectomy. Co-existence of FD/IBS may contribute to this unsatisfactory outcome. METHODS We conducted a multicentre, prospective, observational study (PERFECT-trial). Patients ≥18 years with abdominal pain and gallstones were included at five surgical outpatient clinics between 01/2018-04/2019. Follow-up was six months. Primary outcomes were prevalence of FD/IBS, and the difference between resolution of biliary colic and pain-free state in patients with and without FD/IBS. FD/IBS was defined by the Rome IV criteria, biliary colic by the Rome III criteria, and pain-free by an Izbicki Pain Score ≤10 and visual analogue scale ≤4. RESULTS We included 401 patients with abdominal pain and gallstones (assumed eligible for cholecystectomy), mean age 52 years, 76% females. Of these, 34.9% fulfilled criteria for FD/IBS. 64.1% fulfilled criteria for biliary colic and 74.9% underwent cholecystectomy, with similar operation rates in patients with and without FD/IBS. Post-cholecystectomy, 6.1% of patients fulfilled criteria for biliary colic, with no significant difference between those with and without FD/IBS at baseline (4.9% vs. 8.6%, p = 0.22). Of all patients, 56.8% was pain-free after cholecystectomy, 40.7% of FD/IBS-group vs. 64.4% of no FD/IBS-group, p < 0.001. CONCLUSION One-third of patients eligible for cholecystectomy fulfil criteria for FD/IBS. Biliary colic is reported by only a few patients post-cholecystectomy, whereas non-biliary abdominal pain persists in >40%, particularly in those with FD/IBS pre-cholecystectomy. Clinicians should take these symptom-dependent outcomes into account in their shared decision making process. TRIAL REGISTRATION The Netherlands Trial Register NTR-7307. Registered on 18 June 2018.

Abstract
Gastrointestinal (GI) diseases, which include gastrointestinal reflux disease, gastric ulceration, inflammatory bowel disease, and other functional GI disorders, have become prevalent in a large part of the world population. Metabolic syndrome (MS) is cluster of disorders including obesity, hyperglycemia, hyperlipidemia, and hypertension, and is associated with high rate of morbidity and mortality. Gut dysbiosis is one of the contributing factors to the pathogenesis of both GI disorder and MS, and restoration of normal flora can provide a potential protective approach in both these conditions. Bioactive dietary components are known to play a significant role in the maintenance of health and wellness, as they have the potential to modify risk factors for a large number of serious disorders. Different classes of functional dietary components, such as dietary fibers, probiotics, prebiotics, polyunsaturated fatty acids, polyphenols, and spices, possess positive impacts on human health and can be useful as alternative treatments for GI disorders and metabolic dysregulation, as they can modify the risk factors associated with these pathologies. Their regular intake in sufficient amounts also aids in the restoration of normal intestinal flora, resulting in positive regulation of insulin signaling, metabolic pathways and immune responses, and reduction of low-grade chronic inflammation. This review is designed to focus on the health benefits of bioactive dietary components, with the aim of preventing the development or halting the progression of GI disorders and MS through an improvement of the most important risk factors including gut dysbiosis.

Yao X, Yang Y, Zhang S, Shi Y, Zhang Q, Wang Y. The impact of overlapping functional dyspepsia, belching disorders and functional heartburn on anxiety, depression and quality of life of Chinese patients with irritable bowel syndrome. BMC Gastroenterol 2020; 20:209. [PMID: 32631285 PMCID: PMC7336672 DOI: 10.1186/s12876-020-01357-1;] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2019] [Accepted: 06/23/2020] [Indexed: 06/16/2023] Open
Abstract
BACKGROUND Functional dyspepsia (FD), belching disorders (BD) and functional heartburn (FH) are the three most common upper functional gastrointestinal disorders (FGID) in IBS patients. FD is known to exert deleterious effects on health-related quality of life (HRQoL) and the psychological status of IBS patients; however, the impact of overlapping BD and FH on anxiety, depression and HRQoL of IBS patients remains unknown. This cross-sectional study was conducted to investigate the impact of overlapping FD, BD and FH on anxiety, depression and HRQoL in patients with IBS. METHODS This study enrolled 319 consecutive outpatients with IBS from 2 tertiary hospitals in Beijing and Shijiazhuang of China. IBS, FD, BD and FH were diagnosed using the Rome III Criteria. Hospital Anxiety and Depression Scale and a 36-item Short-Form Health Survey (SF-36) were used to assess the psychological distress and HRQoL of patients respectively. RESULTS Among the 319 patients with IBS, the IBS subtypes were diarrhoea (67%), constipation (16%), unsubtyped (12%) and mixed (5%). These IBS patients were further classified into IBS + FD, IBS + BD/FH (BD and/or FH), IBS + FD + BD/FH, or IBS only according to the patients' overlapping upper GI symptoms. IBS+FD patients reported higher levels of anxiety than IBS+BD/FH and elevated depression scores than IBS only patients (P< 0.05). The latter observation remained consistent after confounder-adjustment. The IBS + FD and IBS + FD + BD/FH groups exhibited statistically significant impairment in most of SF-36 scales, while the IBS + BD/FH group only showed lower HRQoL results in general health, when compared to the IBS only group. Multiple linear regression analysis demonstrated IBS + FD + BD/FH was linked to worse mental, physical and global HRQoL. Furthermore, IBS + FD was a strong predictor of poorer physical and global HRQoL compared to IBS only. CONCLUSIONS Among the diarrhoea-prevalent IBS patients, those with concomitant FD experienced more psychological distress and demonstrated poorer physical HRQoL. Overlapping FD + BD/FH is a significant predictor of worse mental and physical HRQoL for IBS patients. The impact of concomitant BD and FH on the psychological status and HRQoL of IBS patients was limited. These findings implied that the overlapping upper FGIDs in IBS might be treated distinctively when developing comprehensive management strategies for IBS treatment.
