Treatment of functional dyspepsia in Chinese adult patients with domperidone: A multicenter, randomized, double-blind, placebo-controlled pilot study. J Dig Dis 2023; 24:603-610. [PMID: 37902019 DOI: 10.1111/1751-2980.13237] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 04/04/2023] [Accepted: 10/27/2023] [Indexed: 10/31/2023]
Abstract
OBJECTIVE This pilot study aimed to evaluate the efficacy and safety of domperidone for the treatment of Chinese patients with functional dyspepsia (FD) who were diagnosed according to the Rome IV criteria and to identify the FD subtypes that potentially responded better to domperidone. METHODS This multicenter prospective study was conducted in China from August 2018 to July 2020, consisting of a 1-week screening phase and a 2-week double-blind treatment phase. Participants were randomized to receive domperidone 10 mg or matching placebo tablets thrice daily for 14 days. The primary end-point was the overall treatment effect (OTE) response rate after 2-week therapy. RESULTS Altogether 160 patients were included, with 80 patients in each group. The OTE response rate after 2-week therapy was significantly higher for domperidone compared with placebo (60.7% vs 46.0%; relative risk [RR] 1.318, 95% confidence interval [CI] 0.972-1.787). Moreover, the OTE response rate after 2-week domperidone or placebo treatment was 60.3% versus 54.9% for postprandial distress syndrome (PDS) (RR 1.098, 95% CI 0.750-1.607) and 60.6% versus 35.2% for overlapping PDS-epigastric pain syndrome (EPS) (RR 1.722, 95% CI 0.995-2.980). Adverse events were reported by seven patients in the domperidone group and 12 patients in the placebo group. None of the adverse events in the domperidone group were serious. CONCLUSION Domperidone showed a positive pattern regarding OTE response rates after 2-week therapy compared to placebo in patients with FD, as well as in subtypes of PDS and overlapping PDS-EPS. No new safety issue was observed.

Abstract
Domperidone is a peripheral dopamine-2 receptor antagonist with prokinetic and antiemetic properties. Its prokinetic effects are mainly manifest in the upper gastrointestinal (GI) tract. Currently its use is restricted to relief of nausea and vomiting in children older than 12 years for a short period of time. However, among (pediatric) gastroenterologists, domperidone is also used outside its authorized indication ("off label") for treatment of symptoms associated with gastro-esophageal reflux disease, dyspepsia, and gastroparesis. Little is known about its efficacy in the treatment of GI motility disorders in children and controversial data have emerged in the pediatric literature. As its use is off label, appropriate knowledge of its efficacy is helpful to support an "off label/on evidence" prescription. Based on this, the purpose of this review is to summarize all evidence on the efficacy of domperidone for the treatment of GI disorders in infants and children and to report an overview of its pharmacological properties and safety profile.

[PMID: 32048788 DOI: 10.1111/nmo.13812] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2019] [Revised: 01/16/2020] [Accepted: 01/16/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND The evidence for different frequencies of acupuncture treatment in postprandial distress syndrome (PDS) is insufficient. This study determined whether 3 sessions per week of acupuncture treatment are superior to 1 session per week for symptomatic outcomes in PDS. METHODS This 16-week randomized clinical pilot trial was conducted in an outpatient setting in China. Patients with PDS were randomly assigned to receive 3 sessions per week of acupuncture (group H) or 1 session per week of acupuncture (group L) for 4 weeks. The primary outcome was the complete elimination of core symptoms at week 4. Secondary outcomes included overall treatment efficacy, dyspepsia symptoms, quality of life, anxiety, and depression. KEY RESULTS Sixty patients were randomized of whom 53 (88.3%) completed this trial. The complete elimination rate of core symptoms was 26.7% (95% CI 12.3%-45.9%) in group H and 10.0% (95% CI 2.1%-26.5%) in group L at week 4 (P = .095). There was a significant difference between H and group L at weeks 8, 12, and 16 (P = .038, .02, and .02). All secondary outcomes were better in group H at all time points. No serious adverse events occurred in either groups. CONCLUSIONS This trial showed that acupuncture, at 3 sessions per week, tended to improve symptoms and the quality of life among patients with PDS as compared to once a week. Acupuncture treatment for 4 weeks was feasible and safe. A larger sample, multicenter, randomized controlled trial of acupuncture for PDS appears to be justified in the future.

Abstract
BACKGROUND Evidence for treating postprandial distress syndrome with acupuncture is limited. AIM We aimed to evaluate the feasibility of verum acupuncture versus sham acupuncture in patients with postprandial distress syndrome. METHODS A total of 42 eligible patients were randomly allocated to either verum acupuncture or sham acupuncture groups in a 1:1 ratio. Each patient received 12 sessions over 4 weeks. The primary outcome was the response rate based on the overall treatment effect (OTE) 4 weeks after randomization. Secondary outcomes included dyspepsia symptom severity and adverse events. RESULTS In each group, 19 patients (91.5%) completed the study. Thirteen patients receiving verum acupuncture and seven patients receiving sham acupuncture were classified as responders according to OTE (61.9% vs 33.3%; rate difference 28.6%; p = 0.06). Dyspepsia symptom severity at the end of treatment also differed significantly between verum acupuncture and sham acupuncture groups (5.9 units vs 3.7 units; between-group difference 2.2 (95% CI, 0.2-4.2); p = 0.04). No serious adverse events occurred. CONCLUSION Four weeks of acupuncture may represent a potential treatment for postprandial distress syndrome. The treatment protocol and outcome measures used in this trial were feasible. Since this was a pilot study, the efficacy of acupuncture still needs to be determined by a larger, adequately powered trial.

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
OBJECTIVES The aim of the study was to evaluate the therapeutic effect of domperidone on children with abdominal pain predominant functional gastrointestinal disorders (AP-FGIDs). METHODS One hundred children (aged 5-12 years) fulfilling Rome III criteria for AP-FGIDs were randomized into 8 weeks of domperidone or placebo treatment. Primary outcomes defined were cure and patient-reported general improvement. Secondary outcomes were reduction in the severity of abdominal pain and increase in gastric motility. Patients were followed up for 6 months. RESULTS Eighty-nine (42 in placebo group, 47 in domperidone group) completed the trial at 8 weeks. Seventy-nine completed the 6-month follow-up. When primary outcomes were assessed at 8 weeks, 37 (74%) in the domperidone group and 25 (50%) in the placebo group showed patient-reported general improvement (P = 0.013), whereas no significant difference was observed in cure (22 [44%] vs 14 [28%] P = 0.09). At 6-month follow-up 30 (60%) in the domperidone group and 19 (38%) in the placebo group reported cure (P = 0.028), whereas 44 (88%) in the domperidone group and 33 (66%) in the placebo group showed patient-reported general improvement (P = 0.009). When assessing secondary outcomes at 8 weeks, the domperidone group reported significant reduction in the severity of abdominal pain (54.1% vs 24.7%, P = 0.008) and an increase in the antral motility index (27.5% vs 7.2%, P = 0.029). None of the patients reported intervention-related adverse effects. CONCLUSIONS Domperidone may be a safe and effective therapeutic modality to achieve a lasting remission of symptoms in children with AP-FGIDs.

Abstract
Functional dyspepsia (FD) is a highly prevalent disorder that affects more than 10% of the population. In the past decade, the theoretical underpinning of the concept of FD has begun to change, in light of new data on the underlying pathophysiological mechanisms of this disorder, with a focus on the duodenum. The Rome IV criteria, published in 2016, note that gastroesophageal reflux disease and irritable bowel syndrome overlap with FD more than expected by chance, suggesting that they may be part of the same disease spectrum. Infection by Helicobacter pylori (H. pylori) may explain a minority of cases of FD and in the Rome IV criteria H. pylori-associated dyspepsia (defined as symptom relief after eradication therapy) is considered a separate entity. Duodenal inflammation characterized by increased eosinophils and in some cases mast cells, may impair the intestinal barrier. Post-infectious gastroenteritis is now an established risk factor for FD. Other risk factors may include atopy, owning herbivore pets and exposure to antibiotics, together with gastroduodenal microbiome disturbances. Small bowel homing T cells and increased cytokines in the circulation occur in FD, correlating with slow gastric emptying, and a possible association with autoimmune rheumatological disease supports background immune system activation. A genetic predisposition is possible. FD has been linked to psychological disorders, but in some cases psychological distress may be driven by gut mechanisms. Therapeutic options are limited and, aside from responders to H. pylori eradication, provide only modest and temporary relief. Advances in understanding FD may alter clinical practice, and the treatment of duodenal inflammation or microbiome alterations may lead to a cure for a subset of these patients in the future.

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.

Polymorphisms of 5-HTT LPR and GNβ3 825C>T and Response to Antidepressant Treatment in Functional Dyspepsia: A Study from The Functional Dyspepsia Treatment Trial. Am J Gastroenterol 2017; 112:903-909. [PMID: 28291238 DOI: 10.1038/ajg.2017.52] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2016] [Accepted: 12/01/2016] [Indexed: 12/11/2022]
Abstract
OBJECTIVES The Functional Dyspepsia Treatment Trial reported that amitriptyline (AMI) was associated with adequate relief of functional dyspepsia (FD) symptoms, but the pharmacogenetics of antidepressant response in FD are not known. GNβ3 825C>T CC genotype has been previously linked to FD and TT genotype to antidepressant response in depression. The ss genotype of the 5-HTT LPR variant of the serotonin transporter gene (SLC6A4) has been linked to selective serotonin reuptake inhibitor (SSRI) response. We aimed to examine whether GNβ3 825C>T and 5-HTT LPR polymorphisms result in differential treatment effects in FD patients receiving antidepressant therapy. METHODS Participants were randomized to receive placebo, 50 mg AMI, or 10 mg escitalopram (ESC). The primary end point was adequate relief for ≥5 weeks of the last 10 weeks. Genotyping of GNβ3 825C>T and 5-HTT LPR was performed utilizing PCR-based methods. RESULTS GNβ3 825C>T and 5-HTT LPR genotype data were available for 256 (88%) and 246 (84%) patients, respectively. Both polymorphisms were in Hardy-Weinberg equilibrium. In tests for differential treatment, neither 5-HTT LPR nor GNβ3 825C>T genotype influenced response to therapy (P=0.89 and P=0.54, respectively). Although there was a tendency for a more favorable response to ESC in the SS/LS genotype compared to the LL genotype groups (40% vs. 31% reporting adequate relief of FD symptoms) among those in the ESC treatment arm, this was not significant (P=0.43). CONCLUSIONS GNβ3 825C>T and 5-HTT LPR genetic variants do not alter treatment response to tricyclic and SSRI antidepressants in FD.

A multicenter randomized trial comparing rabeprazole and itopride in patients with functional dyspepsia in Japan: the NAGOYA study. J Clin Biochem Nutr 2017; 60:130-135. [PMID: 28366993 PMCID: PMC5370523 DOI: 10.3164/jcbn.16-106] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2016] [Accepted: 11/22/2016] [Indexed: 12/12/2022] Open
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 AND OBJECTIVE Domperidone is a drug used globally for relieving nausea and vomiting and stimulating breast milk production. Several case reports and studies linked domperidone usage with major cardiovascular adverse events (cardiac arrhythmia and sudden cardiac death). However, multiple randomized controlled efficacy studies failed to detect such adverse events. Our objectives were to systematically review and meta-analyze the association between current domperidone exposure and cardiovascular adverse events. METHODS The first author performed EMBASE, PubMed and Scopus searches to identify human studies assessing the association between current domperidone exposure and cardiac arrhythmia or sudden death. Thirteen related articles were identified and the first and second authors independently reviewed the articles. Six studies were included in the final analysis. Meta-analysis was performed with a random effect model using the inverse variance approach. Heterogeneity was evaluated using the Q statistic and I(2) test. RESULTS Five case-control studies and one case-crossover study were included in this meta-analysis. Pooled risk estimates demonstrated that the current use of domperidone increased the risk of ventricular arrhythmia and sudden cardiac death (pooled adjusted odds ratio = 1.70; 95% confidence interval 1.47-1.97; I(2) = 0%). The I(2) test showed that the underlying population was homogeneous. CONCLUSIONS Evidence from this meta-analysis suggests that current domperidone use increases the risk of cardiac arrhythmia and sudden cardiac death by 70%. Domperidone usage in older populations should be discouraged. Larger observational studies or randomized controlled trials are needed to confirm the findings of this analysis.

Abstract
BACKGROUND The aim of this study is to clarify whether acotiamide and rabeprazole combination therapy can improve clinical symptoms, gastric emptying, and satisfaction with treatment in functional dyspepsia (FD) patients more effectively than acotiamide or rabeprazole monotherapy alone. We also aimed to determine whether acotiamide affects these changes via its effect on gastric emptying and appetite-related hormones such as ghrelin. METHODS We used Rome III criteria to evaluate upper abdominal symptoms and anxiety by the State-Trait Anxiety Inventory (STAI). Gastric motility was evaluated by the (13) C-acetate breath test. Eighty-one FD patients were treated with acotiamide (300 mg/day) (n = 35), acotiamide (300 mg/day) and rabeprazole (10 mg/day) (n = 28), or rabeprazole (10 mg/day) (n = 18) for a period of 4 weeks and followed after 4 weeks of no treatment. Adenocorticotropic hormone (ACTH), cortisol, leptin and ghrelin levels were measured in all FD patients. KEY RESULTS Acotiamide and rabeprazole combination therapy significantly improved postprandial distress syndrome (PDS)-like symptoms (p = 0.018, p = 0.04 and p = 0.041, respectively) and epigastric pain (p = 0.024) as wells as STAI-state scores (p = 0.04) compared to rabeprazole monotherapy. Both acotiamide monotherapy, and acotiamide taken in combination with rabeprazole, significantly (p = 0.001 and p = 0.02, respectively) improved satisfaction with treatment, compared to rabeprazole monotherapy. Acotiamide and rabeprazole combination therapy had no significant effect on ACTH and cortisol levels in FD patients. Of interest, acotiamide monotherapy, and acotiamide and rabeprazole combination therapy, significantly (p < 0.0001 and p = 0.018, respectively) increased acylated ghrelin/total ghrelin ratios and significantly (p = 0.04) improved impaired gastric emptying compared to rabeprazole monotherapy. CONCLUSIONS & INFERENCES Further studies are warranted to clarify how acotiamide treatment improves clinical symptoms in FD patients.

Abstract
BACKGROUND/AIMS Functional dyspepsia (FD) is a gastrointestinal disorder in which the patient suffers from chronic abdominal symptoms despite the absence of organic disease. Benachio Q solution (soln.)® is a new prokinetic herbal medicine. The aim of the present study is to determine the efficacy and safety of Benachio Q soln.® in patients with postprandial distress syndrome (PDS) subtype in FD. METHODS A single-center, randomized, double-blind, placebo-controlled pilot study was performed in 20 patients with PDS. Patients were assigned to receive either Benachio Q soln.® or placebo three times a day. After 4 weeks of treatment, the data on response rates, symptoms severity of PDS and gastric emptying time were analyzed to evaluate its efficacy. Adverse events, laboratory tests and vital sign were analyzed to assess its safety. RESULTS Nine patients were assigned to Benachio group and 10 patients to placebo group. The response rate after 4 weeks was 44.4% and 20.0% in Benachio and placebo group, respectively (p=0.350). The response rate during the first week in Benachio group was better compared to that of placebo group with marginal difference (33.3% vs. 0.0%, p=0.087). Changes of severity score in early satiety on second and third week were -1.8 ± 0.6, -1.9 ± 0.4 and -1.3 ± 0.5, -1.4 ± 0.6 in Benachio and placebo group, respectively (p=0.059 vs. p=0.033). No adverse event was observed. CONCLUSIONS The new herbal drug, Benachio Q soln.® seems to improve the symptoms of PDS subtype in FD and could be used safely. Further larger trial is needed in the future.

Abstract
INTRODUCTION Functional dyspepsia (FD) is a relatively common gastrointestinal clinical condition that remains poorly understood. Controversies remain regarding the definition, pathophysiology and optimum treatment. The current treatment of FD is limited and no established regimen is available. AREAS COVERED Recent advances have improved our understanding of the pathophysiology of the disease and have led to the development of newer tailored therapies. Novel agents such as the motilin receptor agonist camicinal and the muscarinic M1 and M2 receptor antagonist acotiamide appear promising; however, the need for a safe and efficacious treatment remains largely unmet. This review describes the currently available management options for FD and critically evaluates emerging therapies. EXPERT OPINION The optimal treatment for FD is yet to be determined. A proton pump inhibitor or a prokinetic agent constitutes primary treatment. Helicobacter pylori testing and eradication is recommended. Based on currently available data, acotiamide appears promising, particularly in postprandial distress syndrome. Further large-scale multicentered trials are required to define the duration of treatment and the side-effect profile.

Abstract
Patients with dyspepsia may present with associated complaints of abdominal pain, bloating, fullness, acid reflux, and epigastric tenderness on examination. The evaluation of patients with dyspepsia includes taking a comprehensive history and performing a physical examination. Although taking a patient history has its limitations in making an accurate diagnosis, it is useful in guiding the selection of subsequent diagnostic tests. Differential diagnoses of dyspepsia are best addressed using an anatomical approach. Patients with chronic dyspepsia lasting > 1 month should be evaluated for the presence of alarm features. Alarm features mandate an upper gastrointestinal endoscopy examination, as these may be suggestive of a malignancy. In patients without alarm features, a Helicobacter pylori test-and-treat strategy is cost-effective if the prevalence of H. pylori infection is high. Tests for H. pylori infection can be divided into non-invasive and minimally invasive tests. Many different antibiotic combination therapies (eg, triple therapy, quadruple therapy, levofloxacin-based therapy, sequential therapy, concomitant therapy, and probiotics with eradication therapy) are now available for the eradication of H. pylori infection. In patients who are symptomatic without an organic pathology, functional dyspepsia and other causes of abdominal pain need to be considered. Functional dyspepsia is best managed using a multifaceted approach by establishing a good physician-patient relationship, dietary and lifestyle interventions, medical therapy, psychotherapy, and the use of psychotropic medications. This review rationalizes the current-day recommendations for the evaluation and management of patients with dyspepsia in a clinical setting.

Abstract
Background/Aims There have been few studies on the efficacy of proton pump inhibitors and the doses required to treat dyspeptic symptoms observed in clinical practice. The aim of this study was to compare the efficacy of different doses of omeprazole and different administration methods in Helicobacter pylori-negative, dyspeptic patients. Methods Patients with chronic upper abdominal symptoms within the previous 3 months were randomly divided into three groups: a daily, omeprazole 20 mg treatment group (OPZ20, n=61); a daily, omeprazole 10 mg treatment group (OPZ10, n=72); and an on-demand omeprazole 20 mg treatment group (on-demand, n=62). After 4 weeks of administration of the drug, symptom improvement rates were evaluated based on the Overall Global Severity score. Results The rates of symptom improvement after 4 weeks of treatment were 65.6% (40/61) in the OPZ20 group, 47.2% (34/72) in the OPZ10 group, and 50.0% (31/62) in the on-demand group. The OPZ20 group exhibited a significantly higher improvement rate (p=0.034) than the OPZ10 group. The OPZ20 group had significant improvements in regurgitation, postprandial fullness, vomiting, and bloating compared with the OPZ10 group. Conclusions Daily treatment with 20 mg of omeprazole was efficient in treating upper abdominal symptoms. Trial registration: ClinicalTrials.gov, number UMIN000002621.

Abstract
BACKGROUND Functional dyspepsia (FD) is a common problem affecting up to 10-25% of individuals. FD accounts for significant health care costs and affects quality of life but has no definitive treatment. OBJECTIVES The Functional Dyspepsia Treatment Trial (FDTT) aims to test whether treatment with an antidepressant (amitriptyline or escitalopram) leads to improvement of symptoms in patients with moderate to severe FD. DESIGN The FDTT is an international multicenter, parallel group, randomized, double-blind, placebo-controlled trial to evaluate whether 12 weeks of treatment with escitalopram or amitriptyline improves FD symptoms compared to treatment with placebo. Secondly, it is hypothesized that acceleration of solid gastric emptying, reduction of postprandial satiation, and enhanced gastric volume change with a meal will be significant positive predictors of short- and long-term outcomes for those on antidepressants vs. placebo. The third aim is to examine whether polymorphisms of GNβ3 and serotonin reuptake transporter influence treatment outcomes in FD patients receiving a tricyclic antidepressant, selective serotonin reuptake inhibitor therapy, or placebo. METHODS The FDTT enrollment began in 2006 and is scheduled to randomize 400 patients by the end of 2012 to receive an antidepressant or placebo for 12 weeks, with a 6-month post-treatment follow-up. The study incorporates multiple validated questionnaires, physiological testing, and specific genetic evaluations. The protocol was approved by participating centers' Institutional Review Boards and an independent Data Safety Monitoring Board was established for monitoring to ensure patient safety and a single interim review of the data in December 2010 (ClinicalTrials.gov number NCT00248651).

Abstract
Dyspepsia is the medical term for difficult digestion. It consists of various symptoms in the upper abdomen, such as fullness, discomfort, early satiation, bloating, heartburn, belching, nausea, vomiting, or pain. The prevalence of dyspepsia in the western world is approximately 20% to 25%. Dyspepsia can be divided into 2 main categories: "organic" and "functional dyspepsia" (FD). Organic causes of dyspepsia are peptic ulcer, gastroesophageal reflux disease, gastric or esophageal cancer, pancreatic or biliary disorders, intolerance to food or drugs, and other infectious or systemic diseases. Pathophysiological mechanisms underlying FD are delayed gastric emptying, impaired gastric accommodation to a meal, hypersensitivity to gastric distension, altered duodenal sensitivity to lipids or acids, altered antroduodenojenunal motility and gastric electrical rhythm, unsuppressed postprandial phasic contractility in the proximal stomach, and autonomic nervous system-central nervous system dysregulation. Pathogenetic factors in FD are genetic predisposition, infection from Helicobacter pylori or other organisms, inflammation, and psychosocial factors. Diagnostic evaluation of dyspepsia includes upper gastrointestinal endoscopy, abdominal ultrasonography, gastric emptying testing (scintigraphy, breath test, ultrasonography, or magnetic resonance imaging), and gastric accommodation evaluation (magnetic resonance imaging, ultrasound, single-photon emission computed tomography, and barostat). Antroduodenal manometry can be used for the assessment of the myoelectrical activity of the stomach, whereas sensory function can be evaluated with the barostat, tensostat, and satiety test. Management of FD includes general measures, acid-suppressive drugs, eradication of H. pylori, prokinetic agents, fundus-relaxing drugs, antidepressants, and psychological interventions. This review presents an update on the diagnosis of patients presenting with dyspepsia, with an emphasis on the pathophysiological and pathogenetic mechanisms of FD and the differential diagnosis with organic causes of dyspepsia. The management of uninvestigated and FD, as well as the established and new pharmaceutical agents, is also discussed.

Abstract
IMPORTANCE OF THE FIELD Dyspeptic symptoms are highly prevalent in the population and represent a major burden for healthcare systems. The ROME III criteria address and define two separate entities of functional dyspepsia: epigastric pain syndrome and postprandial distress syndrome. The etiology of dyspeptic symptoms is heterogeneous, underlying mechanisms are poorly understood and symptomatic improvement after drug therapy is often incomplete. AREAS COVERED IN THIS REVIEW This review of the literature included Medline data being published in the field of functional dyspepsia and different therapies. WHAT THE READER WILL GAIN The reader will gain a current, unbiased understanding of the pathophysiological mechanisms underlying functional dyspepsia and of the therapeutic regimens based on randomized, controlled trials and on the meta-analyses that have been published on different therapeutic agents. TAKE HOME MESSAGE Before starting medical treatment, a careful physical examination should exclude 'alarm symptoms'. Laboratory data, ultrasound and endoscopy are recommended in patients older than 45 - 55 years (depending on the guidelines being used). In areas with a high prevalence of Helicobacter pylori, the initial strategy includes 'test and treat' for H. pylori in addition to empiric acid suppressive therapy. Many studies have focused on the role of gastrointestinal dysmotility and hypersensitivity for dyspepsia with inconclusive results. Further therapeutic medical strategies include prokinetics, herbal preparations and psycho-/neurotopic drugs as well as additional psycho- or hypnotherapy.

Abstract
BACKGROUND Intestinal failure (IF) is the dependence upon parenteral nutrition to maintain minimal energy requirements for growth and development. It may occur secondary to a loss of bowel length, disorders of motility, or both. Short bowel syndrome (SBS) is a malabsorptive state resulting from surgical resection, congenital defect, or diseases associated with loss of absorptive surface area. A particularly vexing problem is associated with whole bowel and/or segmental intestinal dysmotility. Motility disorders within the context of SBS and IF may relate to rapid intestinal transit secondary to loss of intestinal length, dysmotility associated with loss or poor antegrade peristalsis, or gastroparesis. Therapy may be classified into medical (prokinetic and antidiarrheal agents) and surgical to deal with the overdistended poorly motile bowel. METHODS We performed a systematic review of the literature pertaining to IF, SBS, and dysmotility in the pediatric population with gastroschisis, necrotizing enterocolitis, and intestinal atresia. In addition to the available treatment options, we have provided a review of the literature and a summary of the available evidence. CONCLUSION Despite relatively poor level of evidence regarding the application of promotility and antidiarrheal medications in patients with SBS and IF, these agents continue to be used. Herein, we provide a review of the physiology and pathophysiology of intestinal motility/dysmotility and available strategies for the use of promotility and antidiarrheal agents in patients with IF/SBS.

Abstract
BACKGROUND Taraxacum officinale (TO) is a traditional herbal medicine that has been widely used for abdominal illnesses. However, the efficacy and the mechanism of TO on gastric emptying (GE) and smooth muscle motility are unknown. METHODS Ethyl acetate fraction (EA), n-butanol fraction (BF), and aqueous fraction (AF) were prepared in succession from 70% ethanol extract (EE) of TO using solvent polarity chromatography. Phenol red meal was adopted to estimate GE in mice. A polygraph was used to measure the smooth muscle motility in rats. KEY RESULTS The percentage of GE was 48.8 ± 6.1% (vehicle control), 75.3 ± 6.5% (cisapride positive control), 68.0±6.7% (EE), 53.3±6.0% (EA), 54.1±6.3% (AF), and 86.0±6.5% (BF). Thus, BF was determined to be most effective in accelerating GE. This stimulatory effect of BF on GE was also supported by the observation that BF increased spontaneous contraction of gastric fundus and antrum and decreased the spontaneous motility of pyloric sphincter in vitro. Atropine blocked the stimulatory effect of BF on GE, whereas phentolamine and propranolol had no effect. CONCLUSIONS & INFERENCES BF seems to be a promising prokinetic agent. BF-induced increase in the contraction of fundus and antrum contributes to an increase in the intra-gastric pressure. BF-induced decrease in the motility of pyloric sphincter contributes to a decrease in the resistance of food from the stomach to the small intestine. The acceleration of GE by BF is likely to be exerted through cholinergic stimulation.

Abstract
Functional dyspepsia (FD) is defined as the presence of symptoms thought to originate in the gastroduodenal area, in the absence of any organic, systemic, or metabolic disease that is likely to explain the symptoms. Based on the available evidence and consensus opinion, thirteen consensus statements for the treatment of FD were developed using the modified Delphi approach. Proton pump inhibitor, prokinetics, and histamine 2 receptor antagonists are effective for the treatment of FD. Mucosal protecting agents, fundus relaxant, and drugs for visceral hypersensitivity can improve symptoms in FD. Antacids and antidepressants may help improving symptoms in FD. Comparing endoscopy with 'test and treat' of Helicobacter pylori, endoscopy may be more effective initial strategy for managing patients with FD in Korea given high incidence of gastric cancer and low cost of endoscopy. Helicobacter pylori eradication can be one of the therapeutic options for patients with FD. Psychotherapy is effective for those who have severe symptoms and refractoriness. Further studies are strongly needed to develop better treatment strategies for Korean patients with FD.

Abstract
BACKGROUND The commonest cause of upper gastrointestinal symptoms is non-ulcer dyspepsia (NUD) and yet the pathophysiology of this condition has been poorly characterised and the optimum treatment is uncertain. It is estimated that £450 million is spent on dyspepsia drugs in the UK each year. OBJECTIVES This review aims to determine the effectiveness of six classes of drugs (antacids, histamine H2 antagonists, proton pump inhibitors, prokinetics, mucosal protecting agents and antimuscarinics) in the improvement of either the individual or global dyspepsia symptom scores and also quality of life scores patients with non-ulcer dyspepsia. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 4, 2005), MEDLINE (1966 to January 2006), EMBASE (1988 to January 2006), CINAHL (1982 to January 2006), SIGLE, and reference lists of articles. We also contacted experts in the field and pharmaceutical companies. Trials were located through electronic searches of the Cochrane Controlled Trials Register (CCTR), MEDLINE, EMBASE, CINAHL and SIGLE, using appropriate subject headings and text words, searching bibliographies of retrieved articles, and through contacts with experts in the fields of dyspepsia and pharmaceutical companies. SELECTION CRITERIA All randomised controlled trials (RCTs) comparing drugs of any of the six groups with each other or with placebo for non-ulcer dyspepsia (NUD). DATA COLLECTION AND ANALYSIS Two review authors independently assessed eligibility, trial quality and extracted data. MAIN RESULTS We included 73 trials: prokinetics (19 trials with dichotomous outcomes evaluating 3178 participants; relative risk reduction (RRR) 33%; 95% confidence intervals (CI) 18% to 45%), H(2)RAs (12 trials evaluating 2,183 participants; RRR 23%; 95% CI 8% to 35%) and PPIs (10 trials evaluating 3,347 participants; RRR 13%; 95% CI 4% to 20%) were significantly more effective than placebo. Bismuth salts (six trials evaluating 311 participants; RRR 40%; 95% CI -3 to 65%) were superior to placebo but this was of marginal statistical significance. Antacids (one trial evaluating 109 participants; RRR -2%; 95% CI -36% to 24%) and sucralfate (two trials evaluating 246 participants; RRR 29%; 95% CI -40% to 64%) were not statistically significantly superior to placebo. A funnel plot suggested that the prokinetic results could be due to publication bias or other small study effects. AUTHORS' CONCLUSIONS There is evidence that anti-secretory therapy may be effective in NUD. The trials evaluating prokinetic therapy are difficult to interpret as the meta-analysis result could have been due to publication bias. The effect of these drugs is likely to be small and many patients will need to take them on a long-term basis so economic analyses would be helpful and ideally the therapies assessed need to be inexpensive and well tolerated.

Proton pump inhibitor versus prokinetic therapy in patients with functional dyspepsia: is therapeutic response predicted by Rome III subgroups? J Gastroenterol 2011; 46:183-90.

Abstract
BACKGROUND The comparative effectiveness of proton pump inhibitor versus prokinetic therapy in relieving the symptoms of patients with functional dyspepsia remains unknown. Whether the Rome III subgroups predict therapeutic response has not been investigated. METHODS This was an open-label, parallel randomized controlled trial. A total of 329 adult outpatients fulfilling the Rome III criteria for functional dyspepsia were randomly allocated to receive either lansoprazole 30 mg once daily (n = 166) or mosapride 5 mg thrice daily (n = 163) for 2 weeks. Enrolled patients were evaluated with the validated Hong Kong Index questionnaire for symptom severity at baseline and at the end of the trial. The primary outcome was symptom relief as defined by the Hong Kong Index, and the secondary outcome was decrease of symptom scores. Post-hoc multivariate logistic regression analysis was conducted to identify independent predictors for therapeutic response. RESULTS After 2-week therapy, 50.6% (84/166) and 47.85% (78/163) of the patients treated with lansoprazole and mosapride, respectively, achieved significant symptom relief (odds ratio 1.12, 95% confidence interval 0.72-1.72, p = 0.62). Differences in decreases of symptom scores between lansoprazole and mosapride receivers were also insignificant (-0.08, 95% confidence interval -1.25 to 1.09, p = 0.89). Therapeutic responses to either pharmacotherapy did not differ in the subgroup of patients fulfilling the criteria for epigastric pain syndrome (n = 256) or in those fulfilling the criteria for postprandial distress syndrome (n = 161). Multivariate logistic regression confirmed that the treatment allocation and Rome III subgroup were unrelated to treatment outcome. CONCLUSIONS The effectiveness of proton pump inhibitor therapy and that of prokinetic therapy in functional dyspepsia are not different, and cannot be predicted by Rome III subgroups (ClinicalTrials.gov number, NCT00663897).

Abstract
Dyspepsia is a common term used for a heterogeneous group of abdominal symptoms. Functional dyspepsia (FD) is the focus of this review. The 2006 Rome III criteria defined FD and its subgroups, postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). FD is a very common condition with a high prevalence throughout the world, adversely affecting the quality of life of patients. The pathophysiology of FD has been under investigation during the past two decades. Multiple mechanisms such as abnormal gastric emptying, visceral hypersensitivity, impaired gastric accommodation, and central nervous system factors are likely involved. Several tests are available for the assessment of various physiologic functions possibly involved in the pathogenesis of FD, and some of these could be used in clinical practice, helping to understand the abnormalities underlining patients' complaints. Currently, the possibilities of pharmacological therapy for FD are still limited, however, experience of using prokinetics, tricyclic antidepressants, selective serotonin-reuptake inhibitors (SSRIs), proton-pump inhibitors (PPIs), and several alternative techniques has been accumulated. The different combinations of alterations in physiologic gastrointestinal and central nervous system functions result in the very heterogeneous nature of FD so combined approaches to these patients could be beneficial in challenging cases.

Abstract
AIM: To observe the efficacy of acupuncture at acupoints of Foot-Yangming Meridian in the treatment of patient with functional dyspepsia (FD) and to compare with that of unspecific acupuncture.
METHODS: Sixty FD patients were randomly divided into two groups: control group and treatment group. The treatment group was treated by acupuncture at acupoints of Foot-Yangming Meridian, while the control group was treated by unspecific acupuncture. All patients received a total of four treatment cycles, each of which consisted of acupuncture once a day (0.5 h each time) for one week (five times). Immediately before and after the treatment and at one month after the treatment, all patients were requested to fill in several scales, such as Nepean Dyspepsia Index [NDI, including Nepean Dyspepsia Symptom Index (NDSI) and Nepean Dyspepsia Life Quality Index (NDLQI)], FD Symptom Index (FDI), and MOS 36-Item Short-Form Health Survey (SF-36).
RESULTS: The efficacy of acupuncture at acupoints of Foot-Yangming Meridian in improving the symptoms of FD patients was better than that of unspecific acupuncture. The total response rates achieved in treating postprandial fullness, early satiation, epigastric pain, and epigastric burning were significantly higher in the treatment group than in the control groups (85.72% vs19.23%, 78.26% vs 20.00%, 94.11% vs 6.25%, and 60.00% vs 7.69%, respectively; all P < 0.01). At the end of the treatment or at one month after the treatment, NDSI and FDI decreased significantly, and NDLQI and SF-36 increased significantly in the two groups compared to pretherapy values (all P < 0.01). NDSI and FDI were significantly lower, and NDLQI and SF-36 were significantly higher in the treatment group than in the control group (all P < 0.01).
CONCLUSION: Acupuncture at acupoints of Foot-Yangming Meridian is effective in the treatment of FD patients. Both the short-term (at the end of the treatment) and long-term efficacy (one month after the treatment) of acupuncture at acupoints are superior to those of unspecific acupuncture in FD patients.

Abstract
BACKGROUND Herbal remedies are increasingly popular for the treatment of functional dyspepsia. Chios mastic gum is a resinous exudate from the stem of Pistacia lentiscus var. chia. It is a traditional natural remedy used throughout the eastern Mediterranean. The aim of this study was to assess the efficacy of Chios mastic gum in patients with functional dyspepsia. METHODS One hundred and forty eight patients fulfilling Rome II criteria for functional dyspepsia were randomly assigned to receive either Chios mastic gum 350 mg three times daily or placebo. After 3 weeks of treatment the change from baseline in the severity of symptoms of functional dyspepsia was assessed using the Hong Kong index of dyspepsia. Patients' global assessment of efficacy was also evaluated. RESULTS The symptom score after treatment was significantly lower in the Chios mastic gum than in the placebo group ((14.78+/-1.78) vs (19.96+/-1.83)) (p<0.05). There was a marked improvement of symptoms in 40% of patients receiving placebo and in 77% of patients receiving Chios mastic gum (p<0.02). Individual symptoms that showed significant improvement with Chios mastic gum were: stomach pain in general, stomach pain when anxious, dull ache in the upper abdomen and heartburn (<0.05 for all four symptoms). CONCLUSION Chios mastic gum significantly improves symptoms in patients with functional dyspepsia compared to placebo.

Abstract
Delayed gastric emptying in the absence of mechanical obstruction is referred to as gastroparesis. Symptoms that are often attributed to gastroparesis include postprandial fullness, nausea, and vomiting. Although tests of gastric motor function may aid diagnostic labeling, their contribution to determining the treatment approach is often limited. Although clinical suspicion of gastroparesis warrants the exclusion of mechanical causes and serum electrolyte imbalances, followed by empirical treatment with a gastroprokinetic such as domperidone or metoclopramide, evidence that these drugs are effective for patients with gastroparesis is far from overwhelming. In refractory cases with severe weight loss, invasive therapeutics such as inserting a feeding jejunostomy tube, intrapyloric injection of botulinum toxin, surgical (partial) gastrectomy, and implantable gastric electrical stimulation are occasionally considered.

Abstract
BACKGROUND To critically assess the evidence of modified xiaoyao san (MXS) for treating functional dyspepsia (FD). METHODS Systematic literature searches were carried out on the Medline database, CNKI database, Wanfang Data, VIP Information and the Cochrane Library. Reference lists located were checked for further relevant publications. Experts in the field and manufacturers of identified products were contacted for unpublished material. Studies were selected according to predefined inclusion and exclusion criteria. All randomized clinical trials of MXS for treating FD were included. Study selection, data extraction and validation were carried out by at least two reviewers with disagreements being settled by discussion. Weighted means and 95% confidence intervals were calculated and sensitivity analyses were carried out. RESULTS Thirty-three potentially relevant articles were retrieved for further evaluation. Fourteen were suitable for inclusion in the meta-analysis. There was evidence that MXS compared with prokinetic drugs reduced symptoms (odds ratio 3.26, 95% CI 2.24 to 4. 47). There was evidence that MXS + prokinetic drugs compared with prokinetic drugs reduced symptoms (odds ratio 4.32, 95% CI 2.64 to 7.08). CONCLUSION MXS appears to be more effective compared to prokinetic drugs in the treatment of FD and no serious side-effects were identified. However, the evidence remains weak due to publication bias and methodological flaws, which may amplify the therapeutic benefit of MXS.

Abstract
STW 5, a herbal extract, is effective for the treatment of symptoms in patients with functional dyspepsia (FD). However, its mode of action is still unclear and a modulation of gastric motility is hypothesized. This multicentre, placebo-controlled double-blind study addressed the question of whether STW 5 accelerates gastric emptying in patients with FD and gastroparesis. One-hundred and three patients diagnosed with FD were randomly assigned to a treatment with either STW 5 or a liquid placebo for 28 days. The primary end point of the study was a change of a validated gastrointestinal symptom (GIS) score under treatment. Additionally, patients underwent a (13)C octanoic acid breath test for the assessment of the gastric half-emptying time (t(1/2)). Patients with prolonged t(1/2) were diagnosed with gastroparesis and requested to repeat the test at the end of treatment. A change of t(1/2) was defined a secondary study end point. t(1/2) was prolonged in 48.6% of patients in the STW 5 group and in 43.8% of the placebo group. During treatment, t(1/2) increased non-significantly in patients treated with STW 5 (+23 +/- 109 min; P = 0.51) and slightly accelerated among patients in the placebo arm (-26 +/- 51 min; P = 0.77) (P = 0.49). The improvement of the GIS (P = 0.08) and the proportion of patients with a treatment response (P = 0.03) were more pronounced in the STW 5 group. Our findings suggest that the clinical effects of STW 5 in patients with FD and gastroparesis are not directly mediated by an acceleration of gastric emptying. A clear-cut correlation with symptom improvement is still lacking.

Abstract
INTRODUCTION Chemical stimulation with capsaicin in the intestinal lumen induces abdominal pain, presumably through a mechanism involving the polymodal vanilloid receptor TRPV1 (transient receptor potential vanilloid receptor subtype 1). Other stimulators of TRPV1 include heat, acid or ethanol. We evaluated the effects of duodenal acid and ethanol exposure on chemosensitivity and mechanosensitivity in healthy volunteers. METHODS In two placebo-controlled arms of the study, healthy volunteers received duodenal infusions of either hydrochloric acid (0.1 mol/l) (n=8) or ethanol (5% vol/vol) through an oroduodenal tube. Mechanosensitivity was tested applying pressure-controlled duodenal distensions and chemosensitivity was tested by duodenal perfusion with capsaicin (40 microg/ml; 2.5 ml/min). Quality and intensity of upper abdominal symptoms were evaluated with a graded questionnaire during mechanical and chemical stimulation of the duodenum. RESULTS During hydrochloric acid infusion, capsaicin-induced perception was reduced (P<0.01) and latency to discomfort was increased from 24.5 min (25th/75th%:16.5/36 min) during placebo to 50 min (25.5/60 min) (P<0.01). Ethanol had no significant effect on chemosensitivity [latency to discomfort for placebo vs. ethanol: 26 min (18/40 min) vs. 20 min (9/60 min)] (P>0.05). Neither duodenal acidification nor ethanol altered mechanosensitivity significantly (P>0.05). CONCLUSION Duodenal acid activated mechanisms that lead to a decreased sensitivity for intraluminal capsaicin; these mechanisms might protect duodenal chemonociceptors from being sensitized by acid. Whether this mechanism is impaired in patients with upper gastrointestinal functional disease remains to be determined.

Abstract
BACKGROUND Functional dyspepsia is a prevalent condition associated with diminished quality of life (QoL) and high economic burden. AIM To study the efficacy of a combination of flupenthixol and melitracen (F + M) with anxiolytic and antidepressant properties in functional dyspepsia using a randomized controlled cross-over design. METHODS Patients met the Rome III criteria for functional dyspepsia and a validated questionnaire was used to exclude those with anxiety or depression. Moreover, patients had to have failed a trial of acid-suppressive therapy and Helicobacter pylori eradication when positive. End points included subjective global symptom relief and QoL assessed by the Nepean Dyspepsia Index (NDI). RESULTS Twenty-five patients (14 females, 11 males; mean age = 34.3 +/- 9.9 years) were enrolled and 24 completed the 8-week study. There was a significant improvement in subjective global symptom relief with F + M vs. placebo (ITT: 73.9% vs. 26.1%, P = 0.001) and a significant drop in the NDI score vs. placebo (ITT: -9.0 +/- 11.9 vs. -2.4 +/- 8.9, P = 0.03). No difference was noted whether the initial treatment was F + M or placebo. No significant side effects were noted. CONCLUSIONS A combination of F and M is safe and effective in the short-term treatment of functional dyspepsia. F + M is associated with significant improvement in QoL independent of the presence of anxiety or depression.

Abstract
Serotonin (5-hydroxytryptamine or 5-HT) plays a critical physiological role in the regulation of gastrointestinal (GI) function. 5-HT dysfunction may also be involved in the pathophysiology of a number of functional GI disorders, such as chronic constipation, irritable bowel syndrome and functional dyspepsia. This article describes the role of 5-HT in the enteric nervous system (ENS) of the mammalian GI tract and the receptors with which it interacts. Existing serotonergic therapies that have proven effective in the treatment of GI functional disorders and the potential of drugs currently in development are also highlighted. Advances in our understanding of the physiological and pathophysiological roles of 5-HT in the ENS and the identification of selective receptor ligands bodes well for the future development of more efficacious therapies for patients with functional GI disorders.

Abstract
By nature of the definition of functional dyspepsia (FD), organic causes have to be ruled out before therapy can be directed. However, in uninvestigated dyspepsia in the absence of alarm features, Helicobacter pylori "test and treat" or an empiric trial of acid suppression therapy for 4 to 8 weeks is reasonable. If alarm symptoms or signs are present, or if the dyspepsia symptoms first occur in those aged greater than 55 years, prompt esophagogastroduodenoscopy is mandatory to exclude serious disease and positively diagnose FD. Empiric acid suppression with H(2)-receptor antagonists or proton-pump inhibitors is superior to placebo in treatment of FD, but those patients with meal-related symptoms are least likely to respond. Helicobacter pylori eradication in FD benefits a minority of cases but is worthwhile, as response may be maintained. There is increasing evidence that some prokinetics may be superior to placebo in treatment of FD, but probably only a minority respond; those with meal-related symptoms may have the best response. Antidepressant therapy may have a place in management of difficult cases, but adequate randomized controlled trials are unavailable.

Abstract
BACKGROUND Tegaserod, a serotonin receptor type-4 partial agonist, stimulates gastrointestinal motility and has been shown to increase gastric volumes before and after a meal in healthy volunteers. Its effect on gastric motor and sensory function in patients with functional dyspepsia is unclear. AIM To evaluate the effects of tegaserod on gastric compliance, accommodation and gastric sensory function in patients with functional dyspepsia and healthy volunteers. METHODS Sixteen patients with functional dyspepsia and 12 healthy volunteers were studied on two occasions, each after a 7-day treatment with either placebo or tegaserod 6 mg b.d. using a double-blind, randomized, crossover design. After each treatment period a gastric barostat study was performed fasting and during intraduodenal lipid infusion. RESULTS Tegaserod increased postprandial gastric compliance in functional dyspepsia patients (P = 0.04). Healthy volunteers showed enhanced postprandial gastric compliance after placebo (P = 0.03). Between-treatment analysis of gastric accommodation revealed a significant increase in intrabag volumes after tegaserod in healthy volunteer (P = 0.04); no difference could be seen in functional dyspepsia patients. Tegaserod had no effect on gastric sensation. CONCLUSIONS Tegaserod enhances postprandial gastric compliance in functional dyspepsia patients and gastric accommodation in healthy volunteers. The improvement of proximal gastric motor function suggests a beneficial role of tegaserod in patients with functional dyspepsia.

Abstract
BACKGROUND Functional dyspepsia (FD) is often treated with serotonin agonists; however, the efficacy of such agents has recently been questioned. The aim of this study was to perform a meta-analysis of randomized controlled trials (RCTs) comparing serotonin agonists with other types of prokinetics in patients with FD. METHODS Included studies were RCTs that compared serotonin agonists, including cisapride and mosapride, with dopamine antagonists, including metoclopramide and domperidone, and an opiate agonist, trimebutine, in patients with FD. Studies were identified by searching the Medline database (January 1951 - January 2005) and Cochrane Library (Issue 4, 2004), and by manual searches. The difference in the probability of patients' responses between the serotonin agonists and control agents was used as a summary statistic for the treatment effect. Meta-regression analysis was used to detect sources of heterogeneity. RESULTS Five studies were identified. In total, 467 subjects were assigned to a serotonin agonist arm, and 322 subjects were assigned to a control arm. In the overall analysis, the summary statistic was 0.019 (95% confidence interval [CI]: -0.055 to 0.093; P = 0.612), indicating that the patients' responses to serotonin agonists were similar to those to control agents. However, in the stratified meta-analysis of cisapride and mosapride, mosapride had a 6.7% greater probability of producing a response compared with control agents (summary statistic: 0.067; 95% CI: 0.010-0.124; P = 0.021), whereas no significant effect was observed with cisapride. CONCLUSION The data suggest that mosapride may be more effective than cisapride for the treatment of FD. Although FD is a chronic condition, efficacy was assessed over short periods in the studies used for the present meta-analysis. Long-term RCTs are needed to confirm the effect.

Abstract
Domperidone is a dopamine-2 receptor antagonist. It acts as an antiemetic and a prokinetic agent through its effects on the chemoreceptor trigger zone and motor function of the stomach and small intestine. Unlike metoclopramide, it does not cause any adverse neurological symptoms as it has minimal penetration through the blood-brain barrier. It thus provides an excellent safety profile for long-term administration orally in the recommended doses. Domperidone is widely used in many countries and can now be officially prescribed to patients in the United States by an investigational new drug application for the treatment of gastroparesis and any condition causing chronic nausea and vomiting. In view of this additional clinical exposure of domperidone to a new generation of gastroenterologists and other specialists, the purpose of this timely review is to revisit the pharmacology, clinical application, and safety profile of this beneficial medication.

Abstract
Gastroparesis is often difficult to manage. First of all, exact criteria for making a diagnosis of gastroparesis have not been established, and merely finding delayed gastric emptying does not justify the label. Furthermore, the relationship between symptoms and gastric emptying rate is poor, and the number of therapies with proven efficacy is extremely limited. A number of technical investigations are helpful to establish the anatomy and motor function of the upper gastrointestinal tract. In most cases where gastroparesis can be presumed or established, prokinetic therapy will be tried. A number of agents are available, with variable efficacy and tolerance. Rarely, in case of debilitating refractory symptoms, experimental or invasive therapies can be tried such as injection of botulinum toxin, enteral feeding tube insertion, gastric electrical stimulation or surgery.

Abstract
BACKGROUND Functional dyspepsia (FD) constitutes a complex picture with a variety of epigastric symptoms. No standard therapy is currently available for FD. OBJECTIVE This multicenter, placebo-controlled, double-blind study evaluated the efficacy and tolerability of the herbal drug STW 5, mainly comprising a fresh plant extract from Iberis amara. METHODS Patients with FD were included. Gastrointestinal endoscopy, H. pylori-status, and a 7-day run-in phase were required. A total of 315 patients were treated with 3 x 20 drops/day of either STW 5 or placebo. Symptom assessment: day 0, 2, 4, and 8 wk of treatment. The principal outcome criterion was the change in a validated Gastrointestinal Symptom Score (GIS). Symptom severity was rated using the Likert scale. RESULTS A total of 315 patients remained in the safety population. Of them, 158 were treated with STW 5 and 157 with placebo. The intention-to-treat population comprised 308 patients. Dropout number was similar in both groups. GIS showed improvement during the treatment period. The STW 5 group improved 6.9+/-4.8 points up to day 56, placebo group by 5.9+/-4.3 (P<0.05). H. pylori did not influence the results. Drug tolerability and safety were similar in both groups. CONCLUSION This placebo-controlled study with an 8-wk treatment period documents the efficacy of STW 5 in FD.

BACKGROUND Functional dyspepsia (FD) is often treated with prokinetic agents; however, the efficacy of prokinetic agents in patients with FD has been questioned recently. The aim of this study was to perform a meta-analysis of the effects of prokinetic agents in patients with FD. METHODS Prokinetic agents, including metoclopramide, domperidone, trimebutine, cisapride, itopride and mosapride, used for treatment of FD between 1951 and 2005 were identified. Twenty-seven studies were selected. Difference in the probability of response between the interventional drug and placebo was used as a summary statistic for the treatment effect. Meta-regression analysis was used to detect sources of heterogeneity. RESULTS In total, 1844 subjects were assigned to an experimental arm, and 1591 subjects were assigned to a placebo arm. Publication bias was ruled out by funnel plot and statistical testing (P = 0.975). In the overall analysis, the summary statistic was 0.295 (95% confidence interval: 0.208-0.382, P < 0.001), indicating that the interventional drug has 30% excess probability of producing a response compared with placebo. The most significant source of heterogeneity was the year of publication (P < 0.001). CONCLUSION The data clearly indicate that prokinetic agents are significantly more effective than placebo in the treatment of FD. Although FD is a chronic condition, efficacy was assessed over short periods. Long-term randomized controlled trials are needed to confirm the effect.

Abstract
Erythromycin A, the first macrolide, was introduced in the 1950s and after years of clinical experience it still remains a commonly relied upon antibiotic. In the past, pharmacodynamic characteristics of macrolides beyond antimicrobial action such as anti-inflammatory and immune-modulating properties have been of scientific and clinical interest. The function of erythromycin as a prokinetic agent has also been investigated for a range of gastrointestinal motility disorders and more recently within the context of critically ill patients. Prokinetic agents are drugs that increase contractile force and accelerate intraluminal transit. Whilst the anti-inflammatory action may be a desirable side effect to its antibiotic action, using erythromycin A merely for its prokinetic effect alone raises the concern about promoting emergence of macrolide resistance. The objectives of this review article are: (i) to briefly summarize the modes and epidemiology of macrolide resistance, particularly in respect to that found in the Streptococcus species (a potential reservoir for the dissemination of macrolide resistance on the critical care unit); (ii) to discuss in this context the evidence for conditions promoting bacterial resistance against macrolides; and (iii) to assess the potential clinical benefit of using erythromycin A as a prokinetic versus the risks of promoting emergence of macrolide resistance in the clinical setting. We conclude, that in view of the growing weight of evidence demonstrating the potential epidemiological impact of the increased use of macrolides upon the spread of resistance, versus a lack of sufficient and convincing evidence that erythromycin A is a superior prokinetic agent to potential alternatives in the critically ill patient population, at this stage we do not advocate the use of erythromycin A as a prokinetic agent in critically ill patients unless they have failed all other treatment for impaired gastrointestinal dysmotility and are intolerant of metoclopramide. Further large and methodologically robust studies are needed to ascertain the effectiveness of erythromycin A and other alternative agents in the critically ill.
