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.

[PMID: 37129241 DOI: 10.1111/apt.17534] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Revised: 01/23/2023] [Accepted: 04/17/2023] [Indexed: 05/03/2023]
Abstract
BACKGROUND Around 10% of Americans meet the Rome IV criteria for functional dyspepsia (FD), with a significantly higher rate in women. FD also has a higher prevalence in women below the age of 50, suggesting that women who are affected are likely to be of reproductive age. Unfortunately, there is a lack of research or evidence-based guidelines on managing FD in pregnancy. AIMS AND METHODS To address this issue, we aimed to perform a systematic review of the interactions between FD and pregnancy and managing pre-existing FD in the peripartum and post-partum phases using current lifestyle, pharmacological, non-pharmacological and alternative medicine interventions. RESULTS Due to the lack of Rome IV FD-specific data in pregnancy, we instead performed a narrative review on how existing FD interventions could be extrapolated to the pregnant population. Where possible we use the highest level of available evidence or official guidelines to answer these questions, which often involves synthesising treatment and safety evidence of these interventions in other diseases during pregnancy. Finally, we highlight current substantial knowledge gaps requiring further research for the safe management of a pregnant patient with pre-existing FD. CONCLUSIONS Overall, despite the paucity of knowledge of treating FD during pregnancy, providers can mitigate this uncertainty by planning ahead with the patient. Patients should ideally minimise treatment until after breastfeeding. However, interdisciplinary resources are available to ensure that minimal-risk interventions are maximised, while interventions with more risks, if necessary, are justifiable by both the patient and the care team. Future investigations should continue to elicit the mechanistic relationship between FD and pregnancy while cautiously expanding prospective research on promising and safe therapies in pregnant patients with pre-existing FD.

Placebo response in pharmacological trials in patients with functional dyspepsia-A systematic review and meta-analysis. Neurogastroenterol Motil 2023; 35:e14474. [PMID: 36168188 PMCID: PMC10078497 DOI: 10.1111/nmo.14474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 07/18/2022] [Accepted: 09/12/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND Pharmacological trials in functional dyspepsia (FD) are associated with high placebo response rates. We aimed to identify the magnitude and contributing factors to the placebo response. METHODS We conducted a systematic review and meta-analysis including randomized controlled trials (RCTs) with a dichotomous outcome in adult patients with FD that compared an active pharmacotherapeutic treatment with placebo. Our main outcome was identification of the magnitude of the pooled placebo response rate for the following endpoints: symptom responder, symptom-free responder, adequate relief responder, and combined endpoint responder (i.e., the primary endpoint of each specific trial regarding treatment response). Several putative moderators (i.e., patient, disease, and trial characteristics) were examined. KEY RESULTS We included 26 RCTs in our analysis. The pooled placebo response rate was 39.6% (95% CI 30.1-50.0) using the symptom responder definition, 20.5% (12.8-31.0) using the symptom-free responder definition, 38.5% (33.8-43.6) using the adequate relief responder definition, and 35.5% (31.6-39.7) using the combined endpoint responder definition. A lower overall baseline symptom score was significantly associated with a higher placebo response rate. No other moderators were found to significantly impact the placebo response rate. Due to the lack of data, no analyses could be performed according to individual FD subtypes or symptoms. CONCLUSIONS AND INFERENCES The pooled placebo response rate in pharmacological trials in FD is about 39%, depending on which responder definitions is used. Future trials should consider applying an entry criterion based on minimal level of symptom severity to decrease the placebo response. We also suggest separate reporting of core FD symptoms pending more concrete harmonization efforts in FD trials.

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
Gastroparesis is defined by delayed gastric emptying in the absence of mechanical obstruction of the stomach. Patients experience symptoms of nausea, vomiting, abdominal pain, fullness, and early satiety. The recognition of the disorder has progressed due to availability of gastric emptying scintigraphy and advancements made in understanding its pathophysiology and treatment options. The clinical presentation and treatment of gastroparesis overlap with a more commonly recognized disorder of gut-brain interaction, functional dyspepsia. Recent studies have reenergized the discussion whether these two are separate entities or perhaps reflect a spectrum of gastroduodenal neuromuscular disorders. The societal guidelines conflict on the utility of gastric emptying scintigraphy in assessment of patients with upper gastrointestinal symptoms. A better appraisal of similarities and differences between gastroparesis and functional dyspepsia will allow targeted treatment for these disorders. This is particularly important as specific pharmacological and endoscopic treatment options are being developed for gastroparesis which are unlikely to be helpful for functional dyspepsia. This review makes the case for considering these disorders in a spectrum where identification of both would most ideally position us toward providing the optimal clinical care.

Abstract
INTRODUCTION Functional dyspepsia (FD) is a prevalent, but frequently overlooked and/or under diagnosed disorder of gut-brain interaction (DGBI). Functional dyspepsia frequently co-exists with other DGBIs, and persistent symptoms have a significant impact on patients' quality of life. A variety of therapies (e.g. diet, probiotics, antibiotics, acid suppressants, neuromodulators, prokinetics) are employed to treat the multiple symptoms of FD, although none are uniformly effective. AREAS COVERED This review covers currently available therapies for the treatment of FD in addition to novel and emerging therapies that may change the treatment paradigm in the near future. PubMed, Embase and the Cochrane data bank were searched from 1990 to October 2022 for relevant articles. EXPERT OPINION Dietary intervention, eradication of H. pylori, and/or a trial of acid suppression are reasonable initial treatment options for patients with FD. Neuromodulators and fundic accommodation agents are underemployed and should be used more routinely by healthcare providers, especially for patients with moderate-severe symptoms. Alternative therapies, such as cognitive behavioral therapy and hypnotherapy, are gaining recognition as safe and effective treatments for FD and can be used alone or in combination with medications. Virtual reality has the potential to significantly improve global FD symptoms.

Antihyperalgesic and Antiallodynic Effects of Amarisolide A and Salvia amarissima Ortega in Experimental Fibromyalgia-Type Pain. Metabolites 2022; 13:metabo13010059.

Abstract
Salvia amarissima Ortega is an endemic species of Mexico used in folk medicine to alleviate pain and as a nervous tranquilizer. The S. amarissima extract and one of its abundant metabolites, identified and isolated through chromatographic techniques, were investigated to obtain scientific evidence of its potential effects to relieve nociplastic pain such as fibromyalgia. Then, the extract and amarisolide A (3-300 mg/kg, i.p.) were pharmacologically evaluated in reserpine-induced fibromyalgia-type chronic pain and in depressive-like behavior (as a common comorbidity) by using the forced swimming test in rats. The 5-HT1A serotonin receptor (selective antagonist WAY100635, 1 mg/kg, i.p.) was explored after the prediction of a chemical interaction using in silico analysis to look for a possible mechanism of action of amarisolide A. Both the extract and amarisolide A produced significant and dose-dependent antihyperalgesic and antiallodynic effects in rats, as well as significant antidepressive behavior without sedative effects when the antinociceptive dosages were used. The 5-HT1A serotonin receptor participation was predicted by the in silico descriptors and was corroborated in the presence of WAY100635. In conclusion, S. amarissima possesses antihyperalgesic, antiallodynic, and anti-depressive activities, partially due to the presence of amarisolide A, which involves the 5-HT1A serotonin receptor. This pharmacological evidence suggests that S. amarissima and amarisolide A are both potential alternatives to relieve pain-like fibromyalgia.

Abstract
Functional dyspepsia (FD) is a common disorder of gut-brain interaction, affecting approximately 7% of individuals in the community, with most patients managed in primary care. The last British Society of Gastroenterology (BSG) guideline for the management of dyspepsia was published in 1996. In the interim, substantial advances have been made in understanding the complex pathophysiology of FD, and there has been a considerable amount of new evidence published concerning its diagnosis and classification, with the advent of the Rome IV criteria, and management. The primary aim of this guideline, commissioned by the BSG, is to review and summarise the current evidence to inform and guide clinical practice, by providing a practical framework for evidence-based diagnosis and treatment of patients. The approach to investigating the patient presenting with dyspepsia is discussed, and efficacy of drugs in FD summarised based on evidence derived from a comprehensive search of the medical literature, which was used to inform an update of a series of pairwise and network meta-analyses. Specific recommendations have been made according to the Grading of Recommendations Assessment, Development and Evaluation system. These provide both the strength of the recommendations and the overall quality of evidence. Finally, in this guideline, we consider novel treatments that are in development, as well as highlighting areas of unmet need and priorities for future research.

Abstract
PURPOSE OF REVIEW In this review, we evaluate recent findings related to the association between gastrointestinal hormones and regulation of gastric emptying. RECENT FINDINGS Motilin and ghrelin, which act during fasting, promote gastric motility, whereas most of the hormones secreted after a meal inhibit gastric motility. Serotonin has different progastric or antigastric motility effects depending on the receptor subtype. Serotonin receptor agonists have been used clinically to treat dyspepsia symptoms but other hormone receptor agonists or antagonists are still under development. Glucagon-like peptide 1 agonists, which have gastric motility and appetite-suppressing effects are used as a treatment for obesity and diabetes. SUMMARY Gastrointestinal hormones play an important role in the regulation of gastric motility. Various drugs have been developed to treat delayed gastric emptying by targeting gastrointestinal hormones or their receptors but few have been commercialized.

Abstract
Functional gastrointestinal disorders (FGIDs) have been re-named as disorders of gut-brain interactions. These conditions are not only common in clinical practice, but also in the community. In reference to the Rome IV criteria, the most common FGIDs, include functional dyspepsia (FD) and irritable bowel syndrome (IBS). Additionally, there is substantial overlap of these disorders and other specific gastrointestinal motility disorders, such as gastroparesis. These disorders are heterogeneous and are intertwined with several proposed pathophysiological mechanisms, such as altered gut motility, intestinal barrier dysfunction, gut immune dysfunction, visceral hypersensitivity, altered GI secretion, presence and degree of bile acid malabsorption, microbial dysbiosis, and alterations to the gut-brain axis. The treatment options currently available include lifestyle modifications, dietary and gut microbiota manipulation interventions including fecal microbiota transplantation, prokinetics, antispasmodics, laxatives, and centrally and peripherally acting neuromodulators. However, treatment that targets the pathophysiological mechanisms underlying the symptoms are scanty. Pharmacological agents that are developed based on the cellular and molecular mechanisms underlying pathologies of these disorders might provide the best avenue for future pharmaceutical development. The currently available therapies lack long-term effectiveness and safety for their use to treat motility disorders and FGIDs. Furthermore, the fundamental challenges in treating these disorders should be defined; for instance, 1. Cause and effect cannot be disentangled between symptoms and pathophysiological mechanisms due to current therapies that entail the off-label use of medications to treat symptoms. 2. Despite the knowledge that the microbiota in our gut plays an essential part in maintaining gut health, their exact functions in gut homeostasis are still unclear. What constitutes a healthy microbiome and further, the precise definition of gut microbial dysbiosis is lacking. More comprehensive, large-scale, and longitudinal studies utilizing multi-omics data are needed to dissect the exact contribution of gut microbial alterations in disease pathogenesis. Accordingly, we review the current treatment options, clinical insight on pathophysiology, therapeutic modalities, current challenges, and therapeutic clues for the clinical care and management of functional dyspepsia, gastroparesis, irritable bowel syndrome, functional constipation, and functional diarrhea.

Abstract
BACKGROUND Functional dyspepsia (FD) is a disorder that presents with chronic dyspepsia, which is not only very common but also highly affects quality of life of the patients. In Japan, FD became a disease name for national insurance in 2013, and has been gradually recognized, though still not satisfactory. Following the revision policy of Japanese Society of Gastroenterology (JSGE), the first version of FD guideline was revised this time. METHOD Like previously, the guideline was created by the GRADE (grading of recommendations assessment, development and evaluation) system, but this time, the questions were classified to background questions (BQs, 24 already clarified issues), future research questions (FRQs, 9 issues cannot be addressed with insufficient evidence), and 7 clinical questions that are mainly associated with treatment. RESULTS AND CONCLUSION These revised guidelines have two major features. The first is the new position of endoscopy in the flow of FD diagnosis. While endoscopy was required to all cases for diagnosis of FD, the revised guidelines specify the necessity of endoscopy only in cases where organic disease is suspected. The second feature is that the drug treatment options have been changed to reflect the latest evidence. The first-line treatment includes gastric acid-secretion inhibitors, acetylcholinesterase (AChE) inhibitors (acotiamide, a prokinetic agent), and Japanese herbal medicine (rikkunshito). The second-line treatment includes anxiolytics /antidepressant, prokinetics other than acotiamide (dopamine receptor antagonists, 5-HT4 receptor agonists), and Japanese herbal medicines other than rikkunshito. The patients not responding to these treatment regimens are regarded as refractory FD.

Evaluation of QOL in Patients with Dyspeptic Symptoms Who Meet or Do Not Meet Rome IV Criteria. J Clin Med 2021; 11:jcm11010021. [PMID: 35011762 PMCID: PMC8745453 DOI: 10.3390/jcm11010021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Revised: 12/17/2021] [Accepted: 12/18/2021] [Indexed: 11/17/2022] Open
Abstract
Health related quality of life (HR-QOL) of functional dyspepsia (FD) patients is impaired. However, the QOL of such patients has not been fully examined. Accordingly, we examined the QOL of Rome IV defined FD, endoscopic negative dyspeptic patients who do not meet the criteria, (non-FD patients) and healthy subjects, and investigated the factors that influence HR-QOL. This was a multicenter, prospective, observational study. Two hundred thirty-five patients (126 FD, 87 non-FD) and 111 healthy subjects were investigated, and non-FD patients were subdivided into three groups: 17 patients failing to meet only the disease duration criterion (Group A), 53 patients failing to meet only disease frequency criterion (Group B) and 17 patients failing to meet both the disease duration and frequency criteria (Group C). They completed a questionnaire survey regarding gastrointestinal symptoms (GSRS), QOL and psychological factors, which were compared among three groups. The total GSRS score was significantly higher in FD patients than non-FD patients (p = 0.012), which was higher than the healthy subjects (p < 0.0001). Furthermore, the total GSRS score of FD patients was comparable to that of Group A (p = 0.885), which was significantly higher than that of the Group B and C (p = 0.028, p = 0.014, respectively). HR-QOL is more impaired in FD patients than non-FD patients, which was significantly lower than the healthy subjects. That GSRS score in FD and Group A was comparable suggesting that an increased frequency of symptoms may have impact on the impairment of patient’s QOL.

Abstract
BACKGROUND Gastric accommodation is an essential gastric motor function which occurs following ingestion of a meal. Impaired gastric fundic accommodation (IFA) is associated with dyspeptic symptoms. Gastric accommodation is mediated by the vagal pathway with several important physiologic factors such as duodenal nutrient feedback playing a significant role. IFA has been described as a pathophysiologic factor in several gastrointestinal disorders including functional dyspepsia, diabetic gastropathy, post-Nissen fundoplication, postsurgical gastrectomy, and rumination syndrome. Modalities for gastric accommodation assessment include gastric barostat, intragastric meal distribution via scintigraphy, drinking tests (eg, water load), SPECT, MRI, 2D and 3D ultrasound, and intragastric high-resolution manometry. Several treatment options including sumatriptan, buspirone, tandospirone, ondansetron, and acotiamide may improve symptoms by increasing post-meal gastric volume. PURPOSE Our aim is to provide an overview of the physiology, diagnostic modalities, and therapies for IFA. A literature search was conducted on PubMed, Google Scholar, and other sources to identify relevant studies available until December 2020. Gastric accommodation is an important gastric motor function which if impaired, is associated with several upper gastrointestinal disorders. There are an increasing number of gastric accommodation testing modalities; however, each has facets which warrant consideration. Evidence regarding potentially effective therapies for IFA is growing.

Meta-Analysis: Placebo Response and Its Determinants in Functional Dyspepsia. Am J Gastroenterol 2021; 116:2184-2196.

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 Currently, central neuromodulators are among the therapeutic options for the treatment of functional dyspepsia (FD). Pregabalin, a gabapentinoid, is a neuromodulator that could potentially improve visceral hypersensitivity in FD patients. AIM To assess the efficacy and safety of pregabalin for the treatment of FD METHODS: We performed a randomised placebo-controlled study including FD patients who did not respond to proton pump inhibitors. Patients were randomly assigned to receive pregabalin (75 mg daily) or placebo for 8 weeks. The primary outcome was an adequate relief response rate. The secondary outcomes were improvement in quality of life, pain scores in divided categories, and safety profile. RESULTS Of 72 patients enrolled, 34 received pregabalin and 38 received placebo. The self-reported adequate relief rates in the pregabalin and placebo groups were 70.6% and 42.1% at week 4 (P = 0.02), and 70.6% and 44.7% at week 8 (P = 0.03), respectively. The reduction in global symptoms in the pregabalin and placebo groups were 11.7 ± 10.6 and 3.7 ± 8.9 points at week 4 (P < 0.01) and 15.1 ± 12.2 and 8.0 ± 10.2 points at week 8 (P = 0.01), respectively. Pregabalin improved the overall quality of life (P = 0.03). The most common adverse event with pregabalin was dizziness, occurring in 51.6% of patients. CONCLUSIONS Pregabalin led to significant alleviation of dyspeptic symptoms, especially in patients with predominant epigastric pain . Thaiclinicaltrials.org #TCTR20200404002.

Abstract
BACKGROUND Functional dyspepsia (FD) is a relatively common disorder whose pathogenesis has yet been poorly understood. There are still debates concerning definitions and the best possible treatments for this disorder. We aimed to assess the effectiveness of buspirone, a 5-hydroxytryptamine (HT)1A agonist, in improving the symptoms and quality of life (QoL) as well as psychological dimensions in patients with FD. METHODS This study was a randomized, double-blinded, placebo-controlled trial performed on 30 patients with FD, residing in the city of Sari, northern Iran, from December 2017 to October 2018. Consecutive patients referring to a tertiary hospital with a clinical diagnosis of FD, according to the Rome IV criteria, were recruited. All patients were ethnically Persian and had normal upper endoscopy and negative histological evaluation results for any gastrointestinal disease or helicobacter pylori (H. pylori) infection while evaluating biopsy samples endoscopically. Exclusion criteria were being diagnosed with major psychiatric disorders, suicidal thoughts, recent treatments with psychoactive drugs, as well as major cognitive impairments. Patients were randomly assigned to receive either buspirone (n=18) or placebo (n=12) for two months. The first group received buspirone 5mg three times a day for the first month and 10mg three times a day for the second month. During the treatment course, the patients were advised to report any adverse reactions. Also, both groups were evaluated by three questionnaires [demographic characteristics form, the 36-Item Short-Form Health Survey (SF-36), The Short-Form Leeds Dyspepsia Questionnaire (SF-LDQ) and Hospital Anxiety and Depression Scale(HADS)] at the baseline and at the end of the 8th week by a blinded psychologist. Finally, data were analyzed using SPSS software (version 18). P values <0.05 were considered statistically significant. RESULTS The most common symptoms of the patients were FD followed by heartburn. No significant differences were observed between buspirone and placebo groups regarding QoL (p=0.58), anxiety and depression (p =0.36), and severity and frequency of FD symptoms (p =0.22) before and after the intervention. In both groups, the overall QoL as well as HADS and SF-LDQ scores had significantly improved at the end of the study compared with the baseline. CONCLUSION Our findings indicate no significant effects associated with buspirone on the clinical course of FD, compared with placebo. More studies are needed to introduce effective therapies according to the pathophysiology of FD.

Abstract
BACKGROUND Functional dyspepsia (FD) is one of the most common conditions in clinical practice. In spite of its prevalence, FD is associated with major uncertainties in terms of its definition, underlying pathophysiology, diagnosis, treatment, and prognosis. METHODS A Delphi consensus was initiated with 41 experts from 22 European countries who conducted a literature summary and voting process on 87 statements. Quality of evidence was evaluated using the grading of recommendations, assessment, development, and evaluation (GRADE) criteria. Consensus (defined as >80% agreement) was reached for 36 statements. RESULTS The panel agreed with the definition in terms of its cardinal symptoms (early satiation, postprandial fullness, epigastric pain, and epigastric burning), its subdivision into epigastric pain syndrome and postprandial distress syndrome, and the presence of accessory symptoms (upper abdominal bloating, nausea, belching), and overlapping conditions. Also, well accepted are the female predominance of FD, its impact on quality of life and health costs, and acute gastrointestinal infections, and anxiety as risk factors. In terms of pathophysiological mechanisms, the consensus supports a role for impaired gastric accommodation, delayed gastric emptying, hypersensitivity to gastric distention, Helicobacter pylori infection, and altered central processing of signals from the gastroduodenal region. There is consensus that endoscopy is mandatory for establishing a firm diagnosis of FD, but that in primary care, patients without alarm symptoms or risk factors can be managed without endoscopy. There is consensus that H. pylori status should be determined in every patient with dyspeptic symptoms and H. pylori positive patients should receive eradication therapy. Also, proton pump inhibitor therapy is considered an effective therapy for FD, but no other treatment approach reached a consensus. The long-term prognosis and life expectancy are favorable. CONCLUSIONS AND INFERENCES A multinational group of European experts summarized the current state of consensus on the definition, diagnosis and management of FD.

Zhou W, Li X, Huang Y, Xu X, Liu Y, Wang J, Nie G, Zhou D. Comparative efficacy and acceptability of psychotropic drugs for functional dyspepsia in adults: A systematic review and network meta-analysis. Medicine (Baltimore) 2021; 100:e26046. [PMID: 34011118 PMCID: PMC8137050 DOI: 10.1097/md.0000000000026046] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2020] [Revised: 05/01/2021] [Accepted: 05/04/2021] [Indexed: 01/05/2023] Open
Abstract
ABSTRACT Psychotropic drugs are frequently used for functional dyspepsia (FD); however, the efficacy of these drugs for treating FD remains controversial. We aimed to comprehensively compare the relative efficacies of different psychotropic drugs for FD in adults.To conduct this study, we searched the PubMed, Embase, and Cochrane Library databases on March 10, 2019, and conducted a frequentist network meta-analysis on the search results. The primary outcome was treatment efficacy estimated by the proportion of patients who achieved a certain percentage decrease in symptoms or who dropped below the threshold of the global FD symptom scores. The secondary outcome was acceptability, defined as all-cause discontinuation. Odds ratios (ORs) were reported with 95% confidence intervals (CIs).We deemed 10 trials to be eligible for analysis, and these trials included 970 participants and 10 psychotropic drugs. Flupentixol + melitracen (F + M) (OR, 10.00; 95% CI, 1.59 to 62.73), tandospirone (3.24, 1.38 to 7.60), imipramine (2.21, 1.02 to 4.79), and amitriptyline (1.71, 1.06 to 3.09) were significantly superior to placebo. According to the surface under the cumulative ranking curve, the most effective treatment was F + M (89.0%), whereas the least effective was R137696 (13.6%). In terms of acceptability, escitalopram (0.32, 0.11 to 0.92) was ranked as the worst drug (12.6%), followed by imipramine and sertraline.The present network meta-analysis suggests that F + M, tandospirone, imipramine, and amitriptyline are more effective than placebo as treatment for FD. Our results indicate that among the ten psychotropic drugs included, F + M is likely to be the most effective drug for alleviating dyspepsia symptoms.

Abstract
Background Functional dyspepsia (FD) is one of the most common conditions in clinical practice. In spite of its prevalence, FD is associated with major uncertainties in terms of its definition, underlying pathophysiology, diagnosis, treatment, and prognosis. Methods A Delphi consensus was initiated with 41 experts from 22 European countries who conducted a literature summary and voting process on 87 statements. Quality of evidence was evaluated using the grading of recommendations, assessment, development, and evaluation (GRADE) criteria. Consensus (defined as >80% agreement) was reached for 36 statements. Results The panel agreed with the definition in terms of its cardinal symptoms (early satiation, postprandial fullness, epigastric pain, and epigastric burning), its subdivision into epigastric pain syndrome and postprandial distress syndrome, and the presence of accessory symptoms (upper abdominal bloating, nausea, belching), and overlapping conditions. Also, well accepted are the female predominance of FD, its impact on quality of life and health costs, and acute gastrointestinal infections, and anxiety as risk factors. In terms of pathophysiological mechanisms, the consensus supports a role for impaired gastric accommodation, delayed gastric emptying, hypersensitivity to gastric distention, Helicobacter pylori infection, and altered central processing of signals from the gastroduodenal region. There is consensus that endoscopy is mandatory for establishing a firm diagnosis of FD, but that in primary care, patients without alarm symptoms or risk factors can be managed without endoscopy. There is consensus that H. pylori status should be determined in every patient with dyspeptic symptoms and H. pylori positive patients should receive eradication therapy. Also, proton pump inhibitor therapy is considered an effective therapy for FD, but no other treatment approach reached a consensus. The long‐term prognosis and life expectancy are favorable. Conclusions and Inferences A multinational group of European experts summarized the current state of consensus on the definition, diagnosis and management of FD.
Current knowledge
Functional dyspepsia is one of the most common conditions encountered in clinical practice. There is a lack of guidance for clinicians in guiding diagnosis and treatment of this prevalent condition. No treatments are currently approved for the treatment of functional dyspepsia in Europe.
What is new here
A Delphi panel consisting of 41 experts from 22 European countries established the level of consensus on 87 statements regarding functional dyspepsia. The statements reaching consensus serve to guide clinicians in recognizing, diagnosing and treating FD in clinical practice. Endoscopy is mandatory for establishing a firm diagnosis of functional dyspepsia D, but in primary care patients without alarm symptoms or risk factors can be managed without endoscopy. Helicobacter pylori status should be determined in every patient with dyspeptic symptoms and H. Pylori positive patients should receive eradication therapy. Proton pump inhibitor‐therapy is considered an effective therapy for FD, but no other treatment approach reached consensus support.

Abstract
In 2016, the Rome criteria were updated as Rome IV, and only minor changes were introduced for functional dyspepsia (FD). The major symptoms of FD now include not only postprandial fullness, but also epigastric pain and burning, and early satiation at above the "bothersome" level. Investigations into the effect of meal ingestion on symptom generation have indicated that not only postprandial fullness and early satiety but also epigastric pain and burning sensation and nausea (not vomiting) may increase after meals. Helicobacter pylori infection is considered to be the cause of dyspepsia if successful eradication leads to sustained resolution of symptoms for more than 6 months, and such a condition has been termed H. pylori-associated dyspepsia. Prompt esophagogastroduodenoscopy and H. pylori "test and treat" may be beneficial, especially in regions with a high prevalence of gastric cancer, such as east Asia. In terms of treatment, acotiamide, tandospirone, and rikkunshito are newly listed in Rome IV as treatment options for FD. Clinical studies in the field of FD should be strictly based on the Rome IV criteria until the next Rome V is published in 2026.

Abstract
BACKGROUND Functional dyspepsia (FD) is a relapsing and remitting condition affecting between 5% and 10% of people. Efficacious therapies are available, but their relative efficacy is unknown. AIM To perform a systematic review with network meta-analysis to resolve this uncertainty. METHODS We searched the medical literature through July 2020 for randomised controlled trials (RCTs) assessing efficacy of drugs for adults with FD, compared with each other, or placebo. Trials reported a dichotomous assessment of symptom status after completion of therapy. We pooled data using a random effects model. Efficacy was reported as a pooled relative risk (RR) of remaining symptomatic with a 95% confidence interval (CI) to summarise efficacy of each comparison tested. Relative ranking was assessed with surface under the cumulative ranking curve (SUCRA) probabilities. RESULTS We identified 71 eligible RCTs (19 243 participants). Tricyclic antidepressants (TCAs) were ranked second for efficacy (RR of remaining symptomatic = 0.71; 95% CI 0.58-0.87, SUCRA 0.87), and first when only low risk of bias trials were included. Most RCTs that used TCAs recruited patients who were refractory to other drugs included in the network. Although sulpiride or levosulpiride were ranked first for efficacy (RR = 0.49; 95% CI 0.36-0.69, SUCRA 0.99), trial quality was low and only 86 patients received active therapy. TCAs were more likely to cause adverse events than placebo. CONCLUSIONS TCAs, histamine-2 receptor antagonists, standard- and low-dose proton pump inhibitors, sulpiride or levosulpiride, itopride and acotiamide were all more efficacious than placebo for FD.

Abstract
Dyspepsia is a complex of symptoms referable to the gastroduodenal region of the gastrointestinal tract and includes epigastric pain or burning, postprandial fullness, or early satiety. Approximately 80% of individuals with dyspepsia have no structural explanation for their symptoms and have functional dyspepsia. Functional dyspepsia affects up to 16% of otherwise healthy individuals in the general population. Risk factors include psychological comorbidity, acute gastroenteritis, female sex, smoking, use of non-steroidal anti-inflammatory drugs, and Helicobacter pylori infection. The pathophysiology remains incompletely understood, but it is probably related to disordered communication between the gut and the brain, leading to motility disturbances, visceral hypersensitivity, and alterations in gastrointestinal microbiota, mucosal and immune function, and CNS processing. Although technically a normal endoscopy is required to diagnose functional dyspepsia, the utility of endoscopy in all patients with typical symptoms is minimal; its use should be restricted to people aged 55 years and older, or to those with concerning features, such as weight loss or vomiting. As a result of our incomplete understanding of its pathophysiology, functional dyspepsia is difficult to treat and, in most patients, the condition is chronic and the natural history is one of fluctuating symptoms. Eradication therapy should be offered to patients with functional dyspepsia who test positive for Helicobacter pylori. Other therapies with evidence of effectiveness include proton pump inhibitors, histamine-2 receptor antagonists, prokinetics, and central neuromodulators. The role of psychological therapies is uncertain. As our understanding of the pathophysiology of functional dyspepsia increases, it is probable that the next decade will see the emergence of truly disease-modifying therapies for the first time.

Abstract
Gastroparesis presents with nausea, vomiting, and other upper gut symptoms, and is diagnosed by confirming delayed gastric emptying. A related condition, chronic unexplained nausea and vomiting, has similar symptoms but with normal emptying. Both conditions are managed using therapies with diverse mechanisms of action. Even though prokinetic treatments are proposed to improve gastroparesis by accelerating gastric emptying, there is limited evidence that they provide benefit by virtue of transit stimulating effects. Other tests can delineate alterations in other gut sensorimotor parameters in patients with suspected gastroparesis, but their relation to symptoms and their capability to guide treatment are largely unproved.

Abstract
INTRODUCTION Pharmacological interventions have not been successful in the treatment of childhood functional abdominal pain (FAP) hitherto. Buspirone is suggested to be efficacious in some of the abdominal pain-related functional gastrointestinal disorders based on evidences from the studies on adults. We aim to investigate the efficacy of buspirone on childhood FAP. METHODS This randomized clinical trial was conducted on 117 patients with childhood FAP aged 6-18 years. We randomly assigned patients to receive buspirone or placebo for 4 weeks, with the adjusted dosage for age. Participants completed the questionnaires assessing pain, depression, anxiety, somatization, and sleep disturbances at baseline, at the end of the 4-week therapy (first follow-up), and at 8 weeks after medication discontinuation (second follow-up). The primary outcome was treatment response rate, defined as reduced pain score of ≥2 or reporting no pain at the follow-up assessments. RESULTS Ninety-five patients completed the 4-week therapy (48 and 47 in buspirone and placebo groups, respectively). Both buspirone and placebo reduced pain after 4 weeks of treatment, and these effects were persistent 8 weeks after medication discontinuation (P < 0.001 for both groups at weeks 4 and 12). Treatment response rates for buspirone and placebo were 58.3% and 59.6% at week 4 (P = 0.902) and 68.1% and 71.1% at week 12 (P = 0.753), respectively. DISCUSSION Buspirone effectively improves pain and associated psychological symptoms including depressive symptoms, anxiety, somatization, and sleep disturbances in childhood FAP but has no superiority over placebo. Further studies, with the higher doses of buspirone and longer follow-ups are recommended.

Abstract
Hypervigilance and symptoms anticipation, visceral hypersensitivity and gastroduodenal sensorimotor abnormalities account for the varied clinical presentation of functional dyspepsia (FD) patients. Many patients recognize meals as the main triggering factor; thus, dietary manipulations often represent the first-line management strategy in this cohort of patients. Nonetheless, scarce quality evidence has been produced regarding the relationship between specific foods and/or macronutrients and the onset of FD symptoms, resulting in non-standardized nutritional approaches. Most dietary advises are indeed empirical and often lead to exclusion diets, reinforcing in patients the perception of “being intolerant” to food and self-perpetuating some of the very mechanisms underlying dyspepsia physiopathology (i.e., hypervigilance and symptom anticipation). Clinicians are often uncertain regarding the contribution of specific foods to dyspepsia physiopathology and dedicated professionals (i.e., dietitians) are only available in tertiary referral settings. This in turn, can result in nutritionally unbalanced diets and could even encourage restrictive eating behaviors in severe dyspepsia. In this review, we aim at evaluating the relationship between dietary habits, macronutrients and specific foods in determining FD symptoms. We will provide an overview of the evidence-based nutritional approach that should be pursued in these patients, providing clinicians with a valuable tool in standardizing nutritional advises and discouraging patients from engaging into indiscriminate food exclusions.

Abstract
Functional dyspepsia (FD) is a chronic upper gastrointestinal (GI) symptom complex that routine diagnostic work-up, such as endoscopy, blood laboratory analysis, or radiological examination, fails to identify a cause. It is highly prevalent in the World population, and its response to the various available therapeutic strategies is only modest because of the heterogenous nature of its pathogenesis. Therefore, FD represents a heavy medical burden for healthcare systems. We constituted a guideline development committee to review the existing guidelines on the management of functional dyspepsia. This committee drafted statements and conducted a systematic review and meta-analysis of various studies, guidelines, and randomized control trials. External review was also conducted by selected experts. These clinical practice guidelines for FD were developed based on evidence recently accumulated with the revised version of FD guidelines released in 2011 by the Korean Society of Neurogastroenterology and Motility. These guidelines apply to adults with chronic symptoms of FD and include the diagnostic role of endoscopy, Helicobacter pylori screening, and systematic review and meta-analyses of the various treatment options for FD (proton pump inhibitors, H.pylori eradication, and tricyclic antidepressants), especially according to the FD subtype. The purpose of these new guidelines is to aid the understanding, diagnosis, and treatment of FD, and the targets of the guidelines are clinicians, healthcare workers at the forefront of patient care, patients, and medical students. The guidelines will continue to be revised and updated periodically.

Abstract
Introduction: Functional Dyspepsia (FD), defined as chronic symptoms originating from the gastroduodenal region in absence of readily identifiable organic disease, is one of the most common gastrointestinal disorders. FD is divided into two subgroups: Post-Prandial Distress Syndrome (PDS) or meal-related FD, characterized by postprandial fullness and early satiation, and Epigastric Pain Syndrome (EPS) or meal-unrelated FD, characterized by epigastric pain and burning.Areas covered: This review summarizes the existing and off-label therapeutic options for FD.Expert opinion: The identification of mechanisms, the Rome IV classification, the reduction of PDS/EPS overlap and pictograms for symptom identification allow a better diagnosis and a more targeted treatment choice. Acotiamide, a first-in-class prokinetic agent available only in Japan and India, is the only agent of proven efficacy for FD, but clinicians use acid-suppressive therapy, prokinetics, neuromodulators and herbal therapies for treating FD symptoms. New emerging targets are duodenal low-grade inflammation with eosinophils and duodenal or other modified luminal microbiota.

Abstract
Chronic primary pain (CPP) is a group of diseases with long-term pain and functional disorders but without structural or specific tissue pathologies. CPP is becoming a serious health problem in clinical practice due to the unknown cause of intractable pain and high cost of health care yet has not been satisfactorily addressed. During the past decades, a significant role for the descending pain modulation and alterations due to specific diseases of CPP has been emphasized. It has been widely established that central sensitization and alterations in neuroplasticity induced by the enhancement of descending pain facilitation and/or the impairment of descending pain inhibition can explain many chronic pain states including CPP. The descending serotonergic neurons in the raphe nuclei target receptors along the descending pain circuits and exert either pro- or antinociceptive effects in different pain conditions. In this review, we summarize the possible underlying descending pain regulation mechanisms in CPP and the role of serotonin, thus providing evidence for potential application of analgesic medications based on the serotonergic system in CPP patients.

Abstract
BACKGROUND Functional dyspepsia, consisting of epigastric pain syndrome and postprandial distress syndrome, is a prevalent functional gastrointestinal disorder. To date, only limited treatment options are available and conflicting results in terms of efficacy have been reported. Consequently, nonpharmacological treatment options are increasingly being explored for functional dyspepsia. AIM To provide an overview of current pharmacological and nonpharmacological treatment options for functional dyspepsia. METHODS A literature search was conducted on Pubmed and other sources to identify relevant studies. RESULTS Acid suppressive therapy reduced symptoms in 30%-70% of the patients, with higher benefit in epigastric pain syndrome and superior effectiveness for proton pump inhibitors compared to H2 -antagonists. Prokinetic agents, primarily used to treat postprandial distress syndrome, showed variable efficiency: 59%-81% responder rate for dopamine receptor antagonists, 32%-91% for serotonin-4-receptor agonists and 31%-80% for muscarinic receptor antagonists. H Pylori eradication, recommended in infected patients, was effective in 24%-82%. Refractory symptoms are addressed with neuromodulators. However, their efficacy in functional dyspepsia remains incompletely elucidated, available data showing symptom reduction in 27%-71% of the patients. Regarding herbal agents, peppermint oil reduced symptoms in 66%-91%, rikkunshito in 29%-34% and iberogast in 20%-95%. Lastly, acupuncture, cognitive behavioural therapy and hypnotherapy may help to provide symptom control, but research on their efficacy remains sparse. CONCLUSIONS None of the available therapies is effective in the majority of patients without being associated with major side effects. Developing new treatment options is challenging due to the heterogeneity of functional dyspepsia, the lack of readily identified target mechanisms and the poor association between pathophysiological disturbances and symptoms.

Abstract
Functional dyspepsia (FD), defined by the Rome consensus as the presence of functional symptoms originating from the gastroduodenum, is one of the most common functional gastrointestinal disorders. FD is subdivided into postprandial distress syndrome (PDS), with meal-related symptoms such as postprandial fullness and early satiation, and epigastric pain syndrome (EPS), with meal-unrelated symptoms such as epigastric pain or burning. We used a literature search for a narrative review on the current state of knowledge regarding PDS. Areas covered: Epidemiological studies support PDS as a separate entity and the biggest FD subgroup. The pathophysiology of PDS is heterogeneous, and disorders of gastric sensorimotor function as well as low grade duodenal inflammation have been implicated. Although prokinetic agents may provide the most pathophysiology-oriented treatment option, there is a paucity of suitable agents, and proton pump inhibitors are the traditional first-line therapy. Other options include agents that enhance gastric accommodation, such as acotiamide and 5-HT1A agonists, neuromodulators such as mirtazapine, and traditional medicine approaches. Expert commentary: PDS is highly prevalent, with probably heterogeneous underlying pathophysiology. Motility modifying agents and neuromodulators are the cornerstone of PDS therapy, but there is a need for high quality studies of new therapeutic approaches.

Abstract
INTRODUCTION Functional dyspepsia (FD) is typically treated with serotonin receptor (5-HT) agonists such as cisapride, mosapride, tegaserod and tandospirone citrate. However, there are conflicting efficacy data, possibly due to significant heterogeneity between studies. In this meta-analysis, we analyzed the efficacy and safety data from studies evaluating the efficacy of serotonin receptor agonists in patients with FD. MATERIAL AND METHODS Relevant studies were selected from the Medline, Cochrane, EMBASE, and Google Scholar databases. The meta-analysis included 10 RCTs which evaluated the efficacy of serotonin receptor agonists in patients with FD (final total of 892 patients in the serotonin receptor agonist group, and 640 participants in the placebo group). The primary outcomes were the response rates and abdominal symptoms score. The Cochrane Collaboration's tool was used to assess risk. Sensitivity analysis was carried out using the leave-one-out approach. RESULTS Patients treated with serotonin receptor agonists had a significantly higher response rate compared to placebo-treated patients (pooled OR = 2.99; 95% CI: 1.15-7.77; p = 0.025). Patients treated with serotonin receptor agonists had a significant improvement in symptom scores compared to the placebo group (pooled standardized mean difference = -0.43; 95% CI: -0.83 to -0.04; p = 0.031). Sensitivity analysis indicated that the pooled estimates for abdominal symptom score might be affected by the Yeoh et al. (1997) study. CONCLUSIONS Serotonin receptor agonists had a significantly higher efficacy compared to placebo in the treatment of FD.

Abstract
BACKGROUND Dyspepsia is a common condition associated with gastrointestinal (GI) disease. Prokinetics are the treatment of choice for functional dyspepsia (FD). However, the role of prokinetics in FD treatment is still controversial. OBJECTIVES We conducted a systematic review and meta-analysis of randomised control trials (RCTs) examining the efficacy of prokinetics in the treatment of FD. The primary outcome was overall absence of or improvement of symptoms and symptom scores at the end of treatment. We also evaluated quality of life (QoL) and adverse events as secondary outcomes. SEARCH METHODS We performed a systematic search of MEDLINE, Embase, the Cochrane Library, and CINAHL, from 1946 until September 2017. RevMan 5.3 was used to calculate pooled risk ratios (RR) of symptoms persisting or without improved QoL or adverse events, mean difference (MD) or standardised mean difference (SMD) of post-treatment symptoms scores, changes of symptom scores, and QoL, when appropriate with 95% confidence intervals (CI), using a random-effects model. Quality of evidence was evaluated using GRADE methodology. SELECTION CRITERIA We included studies that were parallel group RCTs comparing one prokinetic with either placebo or another prokinetic of the same or different class for the treatment of FD. Studies involved adults who presented with dyspepsia symptoms and who had negative or insignificant findings on endoscopy as well as no other organic and metabolic disorders. Studies only including participants with primarily reflux or heartburn symptoms were excluded. DATA COLLECTION AND ANALYSIS Two review authors independently assessed study eligibility, study quality and performed data extraction. MAIN RESULTS From an initial 1388 citations, we identified 43 studies in 40 papers. Of those, 29 studies with 10,044 participants compared six prokinetics with placebo for the outcome of absence of symptoms or symptom improvement. There was a statistically significant effect of prokinetic treatment in reducing global symptoms of FD (RR of remaining dyspeptic = 0.81, 95% CI 0.74 to 0.89; number needed to treat for an additional beneficial outcome (NNTB) =7, very low-quality evidence) with considerable heterogeneity; I2 = 91% (P < 0.00001). After removing cisapride from the analysis, the effect of prokinetics in global symptom improvement still persisted, compared to placebo (RR 0.87, 95% CI 0.80 to 0.94), but was still based on very low-quality evidence. The result showed persistence of significant improvement in subgroups of studies at unclear or at low risk of bias (RR 0.86, 95% CI 0.80-0.92), and in subgroups by molecules of cisapride (RR 0.71, 95% CI 0.54 to 0.93; NNTB = 4), acotiamide (RR 0.94, 95% CI 0.91 to 0.98; NNTB = 20) and tegaserod(RR 0.89, 95% CI 0.82 to 0.96; NNTB = 14).Ten studies compared different types of prokinetics with each other and the most commonly used comparator was domperidone, 10 mg three times a day (eight of the 10 studies). There was a significantly better post-treatment symptom score in other prokinetics, compared to domperidone (SMD -0.19, 95% CI -0.35 to -0.03, very low-quality evidence), but no difference in reducing global symptom (RR 0.94, 95% CI 0.83 to 1.07), and mean difference symptom scores (SMD -0.13, 95% CI -0.31 to 0.05). We found five studies that assessed quality of life, but there was no benefit in improving quality of life with prokinetic treatment (SMD 0.11, 95% CI -0.10 to 0.33; participants = 1774). The adverse events in individual prokinetics was not different from placebo (RR 1.09, 95% CI 0.95 to 1.25; participants = 3811; studies = 17). However, when we looked at the adverse effects by each prokinetic, there were overall greater adverse effects in the active treatment group with cisapride (RR 1.31, 95% CI 1.03 to 1.65; P = 0.03). The most common side effects were diarrhoea, abdominal discomfort and nausea. The funnel plot was asymmetric (Egger's test, P = 0.02) implying reporting bias or other small-study effects may be, in part, driving the benefit of prokinetics compared to placebo in this meta-analysis. The GRADE assessment of the quality of the evidence in each outcome are mostly low or very low due to concerns around risk of bias in study design, unexplained heterogeneity and possible publication bias. AUTHORS' CONCLUSIONS Due to low, or very low, quality of evidence, we are unable to say whether prokinetics are effective for the treatment of functional dyspepsia . We are uncertain which of the individual prokinetic drugs is the most effective as well as whether prokinetics can improve quality of life. Apart from cisapride, prokinetics are well-tolerated. Good quality RCTs are needed to verify the efficacy of prokinetics.

Abstract
Functional dyspepsia (FD) and gastroparesis are frequent causes of upper gastrointestinal symptoms such as postprandial fullness, early satiation, epigastric pain or burning, upper abdominal bloating, bothersome belching, nausea and vomiting. The underlying pathophysiological mechanisms are heterogeneous and involved mechanisms such as abnormal gastric motility (accommodation, emptying), visceral hypersensitivity, low grade mucosal inflammation and cellular changes in enteric nerves, muscle or interstitial cells of Cajal. Patient-reported outcomes for evaluating treatment efficacy in these conditions were recently developed and validated. Prokinetic agents, which enhance gastric motility, are used for treating both gastroparesis and FD. In FD, besides acid suppressive therapy and Helicobacter pylori eradication, neuromodulators and drugs that enhance gastric accommodation can be applied. In gastroparesis, anti-emetics may also provide symptom relief. Novel approaches under evaluation in these conditions are the fundus relaxing agents acotiamide and buspirone and the antidepressant mirtazapine in FD. For gastroparesis, recently studied agents include the prokinetic ghrelin agonist relamorelin, the prokinetic serotonergic agents velusetrag and prucalopride, the anti-emetic aprepitant and per-endoscopic pyloric myotomy procedures.

Abstract
BACKGROUND AND AIMS The functional gastrointestinal disorders (FGIDs) are extremely common conditions associated with a considerable personal, social and health economic burden. Managing FGIDs in clinical practice is challenging because of the uncertainty of symptom-based diagnosis, the high frequency of overlap between these conditions and the limited efficacy of available therapies. It has often been argued that successful drug development and management of FGIDs requires knowledge of the underlying pathophysiology. Numerous and highly variable candidate pathophysiological mechanisms have been implicated in the generation of FGID symptoms, but there is no current consensus on how to best define the relevance of these disturbances. METHODS A group of international experts on FGIDs developed plausibility criteria that should be fulfilled by relevant pathophysiological mechanisms in FGIDs. RESULTS Five criteria are proposed: (1) the presence of the abnormality in a subset of patients, (2) temporal association between proposed mechanism and symptom(s), (3) correlation between the level of impairment of the mechanism and symptom(s), (4) induction of the symptom(s) by provoking the pathophysiological abnormality in healthy subjects and (5) treatment response by a therapy specifically correcting the underlying disorder or congruent natural history of symptoms and dysfunction in the absence of specific therapy. Based on strength of evidence for these five criteria according to the Grading of Recommendations Assessment, Development and Evaluation system, a plausibility score can be calculated for each mechanism. CONCLUSION Evaluation of the strength of evidence for candidate pathophysiological abnormalities fulfilling these five plausibility criteria will help to identify the most relevant mechanisms to target for novel diagnostic approaches and for the development of new therapies.

Abstract
BACKGROUND AND AIM Gastroesophageal reflux disease (GERD) and functional dyspepsia (FD) often coexist or overlap. In this study, the efficacy of acotiamide in combination with a standard dose of rabeprazole for GERD and FD was compared with that of a double dose of rabeprazole. METHODS Patients with overlap between GERD and FD experiencing heartburn and epigastric fullness symptoms after standard-dose proton pump inhibitor (PPI) for ≥ 8 weeks were randomized into two groups and received either acotiamide 300 mg/day + rabeprazole 10 mg/day or rabeprazole 20 mg/day for 4 weeks. Efficacy was assessed by reductions in symptom scores using the Izumo scale questionnaire and modified F-scale questionnaire. RESULTS As the primary endpoint, three upper gastrointestinal symptoms (heartburn, epigastralgia, and epigastric fullness) were reduced by ≥ 50% in 40.8% and 46.9% of patients in the combination and PPI double-dose groups, respectively, with no significant difference between the two groups. Essentially similar results were obtained for the modified F-scale questionnaire. No serious adverse events were noted. CONCLUSIONS Acotiamide 300 mg/day in combination with rabeprazole 10 mg/day or rabeprazole 20 mg/day relieved symptoms in patients with overlap between GERD and FD experiencing heartburn and epigastric fullness symptoms after standard-dose PPI for ≥ 8 weeks, and the efficacies did not differ between the two treatments. The combination therapy may be an alternative option for persistent symptoms in these patients.

Abstract
Irritable bowel syndrome (IBS), characterized by chronically recurring abdominal pain or discomfort and altered bowel habits and/or stool characters, is a chronic functional gastrointestinal disorder. Patients with IBS are more likely to suffer from coexistent mood disorder, depression, anxiety, and neuroticism. The mechanism of IBS may be related to such factors as abnormal intestinal motility, visceral hypersensitivity, disorder of brain-gut interactions, psychological disturbance and so on. General measures, such as antispasmodics, prokinetic agents, antidiarrheal agents, cathartic agent, and antidepressants are essential for effective IBS management. Anticholinergic agents and monoamine neurotransmitters, including their receptor agonists and antagonists, are all effective treatments for IBS; low-dose therapy can not only mitigate gastrointestinal motility, spasmolysis, and analgesia but also reduce psychological symptoms including anxiety and depression and improve the quality of life. Further larger-scale, long-term, randomized controlled clinical trials are warranted to confirm therapeutic effect and safety of neurotransmitter mediators for treatment of IBS.

Abstract
Objective Functional dyspepsia (FD) is defined as persistent or recurrent pain or discomfort centered in the upper abdomen without organic disease. Psychosocial factors have been proposed as an important element in the pathophysiology of FD. Therefore, psychotropic agents having antianxiety or antidepressive action are expected to alleviate FD. We previously reported on the treatment of FD using such agents in a systematic review, wherein the effectiveness of the agents on FD was suggested, although there were several limitations. We searched for articles on this subject after our systematic review and re-reviewed them systematically. Methods Articles were searched for in MEDLINE from 2003 to 2014 using terms related to antianxiety or antidepressive agents. Clinical studies in which the effectiveness of such agents was clearly stated were selected from the retrieved articles. The newly selected and previously selected studies were combined, and statistical analyses were carried out. Results Nine studies were selected. Five of the studies indicated a significant symptomatic improvement using psychotropic drugs. A statistical analysis suggested a significant treatment effect of psychotropic agents having antianxiety or antidepressive action [pooled relative risk (PRR), 0.72; 95% confidence interval (95% CI), 0.52-0.99; p=0.0406] but did not show a significant benefit of treatment with agents having an antidepressive action alone (PRR, 0.63; 95% CI, 0.38-1.03; p=0.0665). Conclusion Our systematic review suggested that psychotropic drugs having antianxiety and antidepressive actions as a whole might be effective in alleviating FD symptoms, whereas those having only antidepressive action were not effective.

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

Abstract
Patients with functional dyspepsia, defined in the 2016 Rome IV criteria as bothersome clinical dyspepsia symptoms, experience markedly reduced quality of life. Several etiologies have been associated with the disorder. In the Rome IV criteria, the brain-gut axis was acknowledged as an important factor in the etiology of functional gastrointestinal (GI) disorders. The distinct subgroups of functional dyspepsia, epigastric pain syndrome (EPS) and postprandial distress syndrome (PDS), are treated differently: acid secretion inhibitors are recommended with patients with EPS, whereas prokinetic drugs as mosapride and acotiamide are recommended for patients with PDS. A previous study has reported that proton pump inhibitors (PPIs) and H2-blockers were equally effective in functional dyspepsia. A new drug, acotiamide, a muscarinic antagonist and cholinesterase inhibitor, has been shown to improve gastric motility in rodents and dogs, and to reduce PDS symptoms in patients in double-blind multicenter studies. The pharmacological mechanisms of acotiamide remain unknown; whether acotiamide alters gastric emptying and gastric accommodation in patients with functional dyspepsia remains an open question. Other emerging treatment options include Rikkunshito, a herbal medicine that improves gastric emptying through 5-hydroxytryptamine (5-HT)2B-mediated pharmacological action, and tricyclic antidepressants (TCAs). Different drugs are needed to accommodate the clinical symptoms and etiology in individual patients.

Abstract
The Rome criteria were amended as Rome IV. For functional esophageal disorders, the exclusion criteria have been more specifically revised based on further understanding of other esophageal disorders, including eosinophilic esophagitis and spastic and hypercontractile motor disorders. Another revised point is the more restrictive definition of gastroesophageal reflux disease, indicating that sensitivity to a physiological reflux burden may be placed more firmly within the functional group. For functional dyspepsia (FD), only minor changes were introduced, mainly to improve specificity. Among the major symptoms of FD, not only postprandial fullness, but also epigastric pain, epigastric burning, and early satiation should be "bothersome." Investigation on the effect of meal ingestion on symptom generation has indicated that not only postprandial fullness and early satiety, but also epigastric pain, epigastric burning sensation and nausea (not vomiting) may increase after meals. Helicobacter pylori infection is considered a possible cause of dyspepsia if successful eradication leads to sustained resolution of symptoms for more than 6 months, and such status can be termed as "H. pylori-associated dyspepsia." Prompt esophagogastroduodenoscopy and H. pylori testing and treatment would be more beneficial, especially in Asia, which has a high prevalence of gastric cancer. Acotiamide, tandospirone, and rikkunshito are the newly listed as treatment options for FD. For further therapeutic development, clinical studies based on the strict Rome IV criteria should be performed.

Abstract
BACKGROUND In the treatment of functional dyspepsia, the placebo effect has been reported to be high, and the influence of the patient-practitioner relationship may be a major component of this effect. The specific and non-specific effects of acupuncture cannot be easily distinguished, and the patient-practitioner relationship may influence the total therapeutic effect in clinical practice. There have been no studies that investigate the influence of patient-practitioner relationship on acupuncture treatment for patients with functional dyspepsia. METHODS Patients with postprandial distress syndrome, a functional dyspepsia subtype, will be recruited at three hospitals (two in Korea and one in USA) for an international, multi-center, randomized, patient/assessor-blinded, clinical trial. The total anticipated sample size is 88. The participants will be randomly allocated into two groups: an augmented interaction group and a limited interaction group. Acupuncture, with total 12 acupoints, will be performed twice weekly for 4 weeks in both groups. Trained practitioners will provide an "augmented" or "limited" interaction context, as determined by random allocation. The primary outcome measure is the proportion of responders, the proportion of participants who answer "yes" to more than half of the adequate relief questions during the study. Secondary outcome measures include questionnaires for quality of life and symptoms of dyspepsia, and maximum tolerable volume of nutrient drink test. Data will be collected at baseline and following 4 weeks of acupuncture. DISCUSSION This study will evaluate the influence of the patient-practitioner interaction on clinical effects of acupuncture in patients with functional dyspepsia.

Abstract
We have updated both the American College of Gastroenterology (ACG) and the Canadian Association of Gastroenterology (CAG) guidelines on dyspepsia in a joint ACG/CAG dyspepsia guideline. We suggest that patients ≥60 years of age presenting with dyspepsia are investigated with upper gastrointestinal endoscopy to exclude organic pathology. This is a conditional recommendation and patients at higher risk of malignancy (such as spending their childhood in a high risk gastric cancer country or having a positive family history) could be offered an endoscopy at a younger age. Alarm features should not automatically precipitate endoscopy in younger patients but this should be considered on a case-by-case basis. We recommend patients <60 years of age have a non-invasive test Helicobacter pylori and treatment if positive. Those that are negative or do not respond to this approach should be given a trial of proton pump inhibitor (PPI) therapy. If these are ineffective tricyclic antidepressants (TCA) or prokinetic therapies can be tried. Patients that have an endoscopy where no pathology is found are defined as having functional dyspepsia (FD). H. pylori eradication should be offered in these patients if they are infected. We recommend PPI, TCA and prokinetic therapy (in that order) in those that fail therapy or are H. pylori negative. We do not recommend routine upper gastrointestinal (GI) motility testing but it may be useful in selected patients.

Abstract
Since the publication of the 2007 dyspepsia guidelines of the Asociación Mexicana de Gastroenterología, there have been significant advances in the knowledge of this disease. A systematic search of the literature in PubMed (01/2007 to 06/2016) was carried out to review and update the 2007 guidelines and to provide new evidence-based recommendations. All high-quality articles in Spanish and English were included. Statements were formulated and voted upon using the Delphi method. The level of evidence and strength of recommendation of each statement were established according to the GRADE system. Thirty-one statements were formulated, voted upon, and graded. New definition, classification, epidemiology, and pathophysiology data were provided and include the following information: Endoscopy should be carried out in cases of uninvestigated dyspepsia when there are alarm symptoms or no response to treatment. Gastric and duodenal biopsies can confirm Helicobacter pylori infection and rule out celiac disease, respectively. Establishing a strong doctor-patient relationship, as well as dietary and lifestyle changes, are useful initial measures. H2-blockers, proton-pump inhibitors, prokinetics, and antidepressants are effective pharmacologic therapies. H.pylori eradication may be effective in a subgroup of patients. There is no evidence that complementary and alternative therapies are beneficial, with the exception of Iberogast and rikkunshito, nor is there evidence on the usefulness of prebiotics, probiotics, or psychologic therapies. The new consensus statements on dyspepsia provide guidelines based on up-to-date evidence. A discussion, level of evidence, and strength of recommendation are presented for each statement.

Abstract
OBJECTIVE Functional dyspepsia (FD) is a chronic gastroduodenal disorder. Individuals with FD demonstrate visceral hypersensitivity, abnormal central pain processing, and low mood, but it is unclear whether psychotropic drugs are an effective treatment for the condition. We performed a systematic review and meta-analysis of randomised controlled trials (RCTs). DESIGN MEDLINE, EMBASE, EMBASE Classic, PsychINFO and the Cochrane Controlled Trials Register were searched (up to June 2015) for RCTs recruiting adults with FD comparing psychotropic drugs with placebo. We contacted authors directly to maximise trial eligibility and minimise risk of bias for studies. Dichotomous symptom data were pooled to obtain relative risk (RR) of remaining symptomatic after therapy, with 95% CIs. RESULTS The search identified 2795 citations; 13 RCTs (1241 patients) were eligible. Ten trials were at low risk of bias. The RR of FD symptoms not improving with psychotropic drugs versus placebo was 0.78 (95% CI 0.68 to 0.91) (number needed to treat=6; 95% CI 4 to 16). However, benefit was limited to antipsychotics and tricyclic antidepressants. When only studies that excluded individuals with coexistent mood disorder were considered, there was no benefit. Total numbers of adverse events and adverse events leading to withdrawal were significantly more common, with a number needed to harm of 21 for both. CONCLUSIONS Psychotropic drugs may be an effective treatment for FD, but the effect appears to be limited to antipsychotics and tricyclic antidepressants with fewer trials for other agents, meaning that firm conclusions for efficacy cannot be made. More data from high quality RCTs are required to support their use in the treatment of FD.

Abstract
The aims of this study were to compare the therapeutic effects of a proton pump inhibitor (PPI), rabeprazole (RPZ), and a prokinetic agent, itopride (ITO), and to investigate the role of PPI in the treatment strategy for Japanese functional dyspepsia (FD) patients. We randomly assigned 134 patients diagnosed by Rome III criteria to 4 weeks treatment with RPZ 10 mg/day (n = 69) or ITO 150 mg/day (n = 65). Dyspeptic symptoms were evaluated using FD scores at baseline and after 1, 2 and 4 weeks of treatment. We also divided subjects into predominantly epigastric pain syndrome (EPS) or postprandial distress syndrome (PDS), and evaluated the efficacy of RPZ and ITO respectively. RPZ showed a significant decrease in the Rate of Change (RC) in FD score within 1 week, which was maintained until after 4 weeks, with RPZ a significant effect compared with ITO at all evaluation points. In addition, RPZ showed a significant decrease in FD score in subjects with both EPS and PDS, whereas a significant decrease in the RC with ITO was only shown in those with predominant PDS. Acid-suppressive therapy with RPZ is useful for PDS as well EPS in Japanese FD patients (UMIN Clinical Trials Registry number: UMIN 000013962).

Abstract
BACKGROUND Upper gastrointestinal disorders typically present with common symptoms. The most relevant non-mucosal diseases are gastroparesis, functional dyspepsia and rumination syndrome. The literature pertaining to these 3 conditions was reviewed. KEY MESSAGES Gastroparesis is characterized by delayed gastric emptying in the absence of mechanical obstruction of the stomach. The cardinal symptoms include postprandial fullness (early satiety), nausea, vomiting and bloating. The most frequently encountered causes of these symptoms are mechanical obstruction (pyloric stenosis), iatrogenic disease, gastroparesis, functional dyspepsia, cyclical vomiting and rumination syndrome. The most common causes of gastroparesis are neuropathic disorders such as diabetes, idiopathic, post-vagotomy and scleroderma among myopathic disorders. Principles of management of gastroparesis include exclusion of mechanical obstruction with imaging and iatrogenic causes with careful medication and past surgical history. Prokinetics and anti-emetics are the mainstays of treatment. Functional dyspepsia is characterized by the same symptoms as gastroparesis; in addition to delayed gastric emptying, pathophysiological abnormalities include accelerated gastric emptying, impaired gastric accommodation and gastric or duodenal hypersensitivity to distension and nutrients. Novel treatments include tricyclic antidepressants in patients with normal gastric emptying, acotiamide (acetyl cholinesterase inhibitor) and 5-HT1A receptor agonists such as buspirone. Rumination syndrome is characterized by repetitive regurgitation of gastric contents occurring within minutes after a meal. Episodes often persist for 1-2 h after the meal, and the regurgitant consists of partially digested food that is recognizable in its taste. Regurgitation is typically effortless or preceded by a sensation of belching. This has been summarized as a 'meal in, meal out, day in, day out' behavior for weeks or months, differentiating rumination from gastroparesis. Patients often have a background of psychological disorder or a prior eating disorder. Treatment is based on behavioral modification. CONCLUSION Precise identification of the cause and pathophysiology of upper gastrointestinal symptoms is essential for optimal management.
