Abstract
Gastrointestinal (GI) disorders, which extend from the esophagus to the anus, are the most common diseases of the GI tract. Among these disorders, pain, encompassing both abdominal and visceral pain, is a predominant feature, affecting the patients' quality of life and imposing a substantial financial burden on society. Pain signals originating from the gut intricately shape brain dynamics. In response, the brain sends appropriate descending signals to respond to pain through neuronal inhibition. However, due to the heterogeneous nature of the disease and its limited pathophysiological understanding, treatment options are minimal and often controversial. Consequently, many patients with GI disorders use complementary and alternative therapies such as neuromodulation to treat visceral pain. Neuromodulation intervenes in the central, peripheral, or autonomic nervous system by alternating or modulating nerve activity using electrical, electromagnetic, chemical, or optogenetic methodologies. Here, we review a few emerging noninvasive neuromodulation approaches with promising potential for alleviating pain associated with functional dyspepsia, gastroparesis, irritable bowel syndrome, inflammatory bowel disease, and non-cardiac chest pain. Moreover, we address critical aspects, including the efficacy, safety, and feasibility of these noninvasive neuromodulation methods, elucidate their mechanisms of action, and outline future research directions. In conclusion, the emerging field of noninvasive neuromodulation appears as a viable alternative therapeutic avenue for effectively managing visceral pain in GI disorders.

The Influence of Psychological Status on Acupuncture for Postprandial Distress Syndrome: A Subgroup Analysis of a Multicenter, Randomized Controlled Trial. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:1614648. [PMID: 35140795 PMCID: PMC8820860 DOI: 10.1155/2022/1614648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Accepted: 12/09/2021] [Indexed: 01/06/2023]
Abstract
Background Postprandial distress syndrome (PDS) is accompanied by a high incidence of mood disorder. Acupuncture is an effective method in relieving dyspepsia symptoms; however, the impact of psychological status on acupuncture for PDS remains mysterious. Methods This secondary analysis of a multicenter, randomized controlled trial aims to evaluate the influence of anxiety and depression on acupuncture for PDS. 138 patients received the same acupuncture treatment and were followed up until week 16. The 2 primary outcomes were the response rate based on overall treatment effect and the elimination rate of all 3 cardinal symptoms after 4 weeks of treatment. Results Of 114 patients, 31 were anxiety patients and 83 were nonanxiety patients or 32 were depressive patients and 82 were nondepressive patients. The response rate and elimination rate at week 4 were 77.4% and 9.7% in anxiety patients versus 84.3% and 27.7% in nonanxiety patients, respectively (P = 0.388; P = 0.041). No significant difference was noted in the response rate (P = 0.552) and elimination rate (P = 0.254) at week 4 between nondepressive and depressive patients. There was no significant intergroup difference in the response rate and elimination rate between non-mood-disorder and mood disorder patients (P > 0.05) during the 12-week post-treatment follow-up, except for the response rate at week 8 (P < 0.05). Conclusion The effect of acupuncture on response rate was similar for both non-mood-disorder and mood disorder patients. However, anxiety but not depression had a negative influence on the elimination rate, especially in postprandial fullness.

Abstract
Functional dyspepsia (FD), a common disorder of gastrointestinal function, originated from the gastroduodenum. Although the therapeutic effect of acupuncture has been investigated by various high-quality randomized controlled trials, the potential mechanisms showed obvious heterogeneity. This review summarized the potential mechanisms of acupuncture on FD in order to guide for future laboratory and clinical studies. Here, we argued that the primary cause of FD was gastroduodenal low-grade inflammation and acid exposure, which impaired mucosal integrity, caused brain-gut axis dysfunction, and impaired brain network connectivity, all of which generated various symptom patterns. Overall the clinical studies indicated that acupuncture was a promising treatment to alleviate symptoms in FD patients, whose efficacy was influenced by acupoints and individual variance. Mechanistically, studies with animal models of FD and patients have shown that acupuncture, a non-invasive strategy for nerve stimulation, may have the potential to control intestinal inflammation and suppress acid-secretion via different somatic autonomic reflex pathways, regulate the brain-gut axis through intestinal microbiota, and has the potential to ameliorate FD-symptoms. The cumulative evidence demonstrated that acupuncture is a promising treatment to alleviate symptoms of FD patients.

Abstract
Background Clinical research in acupuncture has been criticized for not reflecting real-world practice in terms of diagnosis and intervention. This study aimed to collect data on the principles of diagnosis and selection of acupoints from Korean medicine doctors (KMDs) and analyze the patterns and priorities in decision-making. Methods The study design was based on the data of an actual patient with functional dyspepsia (FD) (according to Rome III criteria) to create simulated patients, and a KMD specialized in gastrointestinal disorders was allocated to collect the clinical information as objectively as possible. Sixty-nine KMDs were recruited to diagnose a simulated patient based on the actual patient's clinical information, in a manner similar to that performed in their clinics. Results After the diagnostic procedures were completed, the pattern identification, selected acupoints, reasons for choosing them, and importance of symptoms for deciding their diagnoses were documented. The information needed was clearly distinguishable from those routinely asked in western medicine, and information regarding fecal status, abdominal examination, appetite status, pulse diagnosis, and tongue diagnosis were listed as vital. The doctors identified the patient's pattern as "spleen-stomach weakness", "liver qi depression", or "food accumulation or phlegm-fluid retention". The most frequently selected acupoints were CV12, LI4, LR3, ST36, and PC6. Conclusion There are common acupoints across different patterns, but pattern-specific acupoints were also recommended. These results can provide useful information to design clinical research and education for better clinical performance in acupuncture that reflects real-world practice.

The selection of dermatomes for sham (placebo) acupuncture points is relevant for the outcome of acupuncture studies: a systematic review of sham (placebo)-controlled randomized acupuncture trials. Acupunct Med 2020; 38:211-226.

Abstract
BACKGROUND Many randomized controlled trials (RCTs) of acupuncture reveal no significant differences between acupuncture and so-called placebo acupuncture. There is a strong tendency to replace the term "placebo" by the term "sham," because any needling stimulates a certain physiological response. However, neither concept accounts for the great diversity of results in RCTs comparing verum acupuncture and sham (placebo) acupuncture. Some trials have shown little or no difference, while other studies have found statistically significant differences. OBJECTIVE Verum acupuncture and sham (placebo) acupuncture may achieve similar results to the extent that they share active constituents. We identified these common active constituents as dermatomes: the segmental structure of the human body. In our study, we tested the hypothesis that the more verum and sham (placebo) acupuncture share the same dermatomes, the closer the clinical outcomes will be, and vice versa. METHODS All major databases were searched for RCTs that tested acupuncture versus sham (placebo) acupuncture. The dermatome charts of Hansen and Schliack were used to verify verum and sham (placebo) needling locations. Reported clinical outcomes were assessed in relation to the percentage of overlap between the dermatomes stimulated by acupuncture and sham (placebo) acupuncture. RESULTS Our literature search yielded a total of 1738 references. Thirty-four studies met the inclusion criteria. The effects of sham (placebo) acupuncture varied according to the dermatomes stimulated: high overlap with those stimulated by verum acupuncture resulted in almost identical efficacy, while low overlap resulted in significant differences in efficacy. Clinical outcomes were similar when verum acupuncture and sham (placebo) acupuncture shared the same dermatomes (p < 0.01). DISCUSSION The findings of this review confirm our hypothesis. Acupuncture studies that employed verum and sham locations on overlapping dermatomes helped to create a mediocre to negative picture of acupuncture's efficacy. The segmental structure of the body with its interconnected reflex system offers an additional neurophysiological explanation for the effectiveness of acupuncture applied to structures segmentally innervated by the spinal and visceral nervous system. Further comparative acupuncture studies should be based on knowledge of segmental anatomy. In testing verum acupuncture versus sham acupuncture, the chosen sham acupuncture needling locations should be situated on non-overlapping dermatomes.

Abstract
BACKGROUND Acupuncture has been widely accepted for treatments of many diseases. This study was performed to determine effects and mechanisms of electroacupuncture (EA) by chronically implanted electrodes at acupoint ST36 on colonic inflammation induced by TNBS in rats. METHODS After intrarectal administration of TNBS, the rats were treated with sham-EA, EA1/EA2 (two sets of parameters) for 3 weeks. Disease activity index (DAI), macroscopic and microscopic lesions, plasma levels of TNF-α, IL-1β and IL-6 were observed as evaluation of inflammatory responses. The autonomic function was assessed by analysis of the heart rate variability. RESULTS (a) Vagal activity was significantly increased with both acute and chronic EA1/EA2; (b) DAI was significantly decreased with both chronic EA1 and EA2, and EA2 was more potent than EA1 (P < 0.05); (c) The macroscopic score was 6.4 ± 0.6 with sham-EA and reduced to 4.9 ± 0.1 with EA1 (P < 0.05) and 4.0 ± 0.2 with EA2 (all P < 0.05). The histological score was 4.05 ± 0.58 with sham-EA and remained unchanged (3.71 ± 0.28) with EA1 (P > 0.05) but reduced to 3.0 ± 0.3 with EA2 (P < 0.01); (d) The plasma levels of TNF-α, IL-1β and IL-6 were significantly decreased with EA2. CONCLUSIONS Electrical stimulation at ST36 improves colonic inflammation in TNBS-treated rats by inhibiting pro-inflammatory cytokines via the autonomic mechanism.

Abstract
BACKGROUND To test the efficacy of electroacupuncture for patients with refractory functional dyspepsia (FD). METHODS A 24-week, 2-arm, single-blind, randomized controlled trial was conducted at three hospitals in China. Patients with refractory FD were randomly assigned to receive 20 sessions of authentic or sham electroacupuncture in a treatment duration of 4 weeks. The primary outcome was complete absence of dyspeptic symptoms at 16 weeks after initiation of acupuncture (week 16). The secondary outcomes included adequate relief of dyspeptic symptoms, Leeds Dyspepsia Questionnaire (LDQ), Nepean Dyspepsia Index (NDI), and adverse events. Intention-to-treat analysis was performed. KEY RESULTS Two hundred patients were included, of which 196 (98%) completed follow-up data at week 24. At week 16, 17 (17%) patients in the authentic electroacupuncture group vs 6 (6%) patients in the sham group achieved the primary outcome (P = .014). Sixty-two (62%) patients had adequate relief in the authentic electroacupuncture group, as compared to 22 (22%) in the sham group (P = .001). The scores of LDQ and NDI were significantly improved in both groups at week 16, and patients in the authentic electroacupuncture group have more improvements (LDQ, mean difference, -2.2, 95% confidence interval, -2.3 to -2.1, P < .001; NDI, -7.3, -10.5 to -4.2, P < .001). Results were similar for all the outcomes assessed at week 24. No serious adverse events were reported in both groups. CONCLUSION Acupuncture efficaciously improves dyspeptic symptoms in patients with refractory FD.

Abstract
INTRODUCTION This trial proposes to compare the effectiveness and cost-effectiveness of electroacupuncture (EA) plus on-demand gastrocaine with waiting list for EA plus on-demand gastrocaine in providing symptom relief and quality-of-life improvement among patients with functional dyspepsia (FD). METHODS AND ANALYSIS This is a single-centre, pragmatic, randomised parallel-group, superiority trial comparing the outcomes of (1) EA plus on-demand gastrocaine group and (2) waiting list to EA plus on-demand gastrocaine group. 132 (66/arm) endoscopically confirmed, Helicobacter pylori-negative patients with FD will be recruited. Enrolled patients will respectively be receiving (1) 20 sessions of EA over 10 weeks plus on-demand gastrocaine; or (2) on-demand gastrocaine and being nominated on to a waiting list for EA, which entitles them 20 sessions of EA over 10 weeks after 12 weeks of waiting. The primary outcome will be the between-group difference in proportion of patients achieving adequate relief of symptoms over 12 weeks. The secondary outcomes will include patient-reported change in global symptoms and individual symptoms, Nepean Dyspepsia Index, Nutrient Drink Test, 9-item Patient Health Questionnaire (PHQ9), and 7-item Generalised Anxiety Disorder Scale (GAD7). Adverse events will be assessed formally. Results on direct medical costs and on the EuroQol (EQ-5D) questionnaire will also be used to assess cost-effectiveness. Analysis will follow the intention-to-treat principle using appropriate univariate and multivariate methods. A mixed model analysis taking into account missing data of these outcomes will be performed. Cost-effectiveness analysis will be performed using established approach. ETHICS AND DISSEMINATION The study is supported by the Health and Medical Research Fund, Government of the Hong Kong Special Administrative Region of China. It has been approved by the Joint Chinese University of Hong Kong - New Territories East Cluster Clinical Research Ethics Committee. Results will be published in peer-reviewed journals and be disseminated in international conference. TRIAL REGISTRATION NUMBER ChiCTR-IPC-15007109; Pre-result.

Abstract
Background Postprandial distress syndrome (PDS) is referred to as meal-related functional dyspepsia (FD) and causes a reduced quality of life (QoL) for patients. Several randomized controlled trials (RCTs) have suggested that acupuncture is an effective treatment for FD, but few studies were particularly for PDS. This pilot study was designed to determine the feasibility and efficacy of acupuncture in patients with PDS characterized by postprandial fullness and early satiation according to the Rome III criteria. Methods This is a multi-center, two-arm, blinded (participants), pilot RCT. Forty-two participants who meet the inclusion criteria will be randomly assigned to the verum acupuncture group or minimal acupuncture group in a 1:1 ratio. Both treatments consist of 12 sessions of 20 min duration over four weeks (three sessions per week). The primary outcome measurement is the proportion of persons who improve as assessed using the global outcome by the overall treatment effect (OTE) at end-of-treatment (EOT) (four weeks after randomization). Global assessment at weeks 8 and 16 after randomization is one of the secondary outcomes. The other secondary outcomes including symptoms, disease-specific QoL, and depression and anxiety will be assessed at weeks 4, 8, and 16 after randomization. Discussion This pilot study will help determine the feasibility and efficacy of acupuncture in patients with PDS. Trial registration ISRCTN Registry, ISRCTN18135146. Registered on 7 July 2016.

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.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2016; 2016:3862916. [PMID: 28119758 PMCID: PMC5227170 DOI: 10.1155/2016/3862916] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/21/2016] [Revised: 10/08/2016] [Accepted: 10/23/2016] [Indexed: 12/20/2022]
Abstract
Background. Although the effectiveness of acupuncture therapy on functional dyspepsia (FD) has been systematically reviewed, the available reports are still contradictive and no robust evidence has been provided to date. Objective. To assess the current evidence of high quality on the effects of acupuncture for patients with FD. Methods. A comprehensive literature database search was conducted to identify randomized controlled trials (RCTs) comparing acupuncture therapies (including manual acupuncture and electroacupuncture) to sham acupuncture and medication use. A meta-analysis was performed following a strict methodology. Results. 16 RCTs involving 1436 participants were included. The majority of the trials were determined to be of low quality. Positive results were found for acupuncture in improving the Nepean Dyspepsia Index (NDI) and scores of the MOS 36-Item Short-Form Health Survey (SF-36), as well as in alleviating relevant symptoms (especially postprandial fullness and early satiation) of FD patients. Conclusion. Based on current available evidence, acupuncture therapy achieves statistically significant effect for FD in comparison with sham acupuncture and is superior to medication (prokinetic agents) in improving the symptoms and quality of life of FD patients. Nonetheless, despite stringent methodological analyses, the conclusion of our review still needs to be strengthened by additional RCTs of higher quality.

Abstract
OBJECTIVES This study was implemented to evaluate the effect of individualized acupuncture treatment (AT) on functional dyspepsia (FD). METHODS A randomized, waitlist-controlled, two-center trial was performed. Seventy-six patients with FD were enrolled in the trial with partially individualized AT in a more realistic clinical setting performed twice a week for 15 minutes a session over 4 weeks. The participants were randomly allocated to a group receiving 8 sessions of AT for 4 weeks or a waitlist control group. After 4 consecutive weeks, the AT group was followed up without AT and the control group received the identical AT. The proportion of responders with adequate symptom relief, Nepean Dyspepsia Index (NDI), FD-related quality of life, Beck Depression Inventory, State-Trait Anxiety Inventory, Acupuncture Belief Scale, and acupuncture credibility test were assessed. RESULTS After the first 4 weeks, the proportion of responders significantly improved (59% in AT group [n = 37] versus 3% in control group [n = 39]; p < 0.001). The difference was no longer significant at 8 weeks, at which point the waitlist control group showed similar improvement after receiving AT (68% in the AT group versus 79% in the control group). Total NDI scores were significantly reduced in the AT group compared with the waitlist group (p = 0.03). Among NDI items, discomfort (p = 0.01), burning (p = 0.02), fullness after eating (p = 0.02), and burping (p = 0.02) were significantly improved in the AT group compared with the control group. No significant differences were observed between groups in other secondary variables. CONCLUSION Individualized AT adequately relieves symptoms in patients with FD, and this effect may persist up to 8 weeks.

Abstract
OBJECTIVES Functional dyspepsia (FD) is a common gastrointestinal disorder. Currently, no established optimal treatment is available. The aim of this study was to assess the efficacy of acupuncture in relieving symptoms and improving quality of life in patients with FD. METHODS PubMed, MEDLINE, Web of Science, Sino-Med, China National Knowledge Infrastructure, VIP databases, and Google Scholar engine were searched from inception through April 2014 to identify randomized controlled trials of acupuncture therapy that reported on overall FD symptoms or FD-related quality of life as a primary outcome. The Cochrane Collaboration's risk of bias tool, RevMan 5.0, and Stata 12.0 software were used for meta-analysis. Data were pooled to calculate relative risk (RRs) and 95% confidence intervals (CIs) of substantial improvement after treatment for dichotomous data and mean differences (SMDs) and 95% CIs for continuous data using random-effects models. RESULTS Twenty-four English- and Chinese-language articles describing randomized, placebo-controlled, clinical trials involving 3097 patients were included. Acupuncture significantly improved FD symptoms in studies reporting outcomes using dichotomous (RR, 1.19; 95% CI, 1.12-1.27; p < 0.001) and continuous (standardized MD [SMD], -0.78; 95% CI, -1.21 to -0.35; p = 0.0004) variables. Pooled analyses showed that acupuncture improved FD-related (weighted MD [WMD], 5.97; 95% CI, 3.14-8.80; p = 0.0002) and health-related (WMD, 6.83; 95% CI, 3.02-10.65; p = 0.004) quality of life, without serious adverse events. However, acupuncture failed to increase plasma motilin concentration (SMD, 0.67; 95% CI, -0.07 to 1.42; p = 0.08). CONCLUSIONS Acupuncture appears to be efficacious in relieving FD symptoms and improving quality of life.

Abstract
Objective. To explore acupuncture effects on brain functional connectivity in patients with functional dyspepsia (FD). Methods. Eight patients in an acupuncture treatment group and ten healthy adults in the control group participated in the study. Acupuncture effectiveness was evaluated based on changes of the gastrointestinal symptoms, gastric motility measurements, and gastrin levels and comparisons with the control group when appropriate. To investigate functional connectivity changes related to FD and potential modulation after acupuncture, a set of regions of interest (ROIs) were selected according to previous fMRI reports of acupuncture. Results. Patients showed significant improvements of FD signs and symptoms after acupuncture treatments. For all of the ROIs, we identified subportions of the networks showing reduced connectivity in patients with FD. Connectivity between the ROIs and corresponding disease targets showed significant improvement after acupuncture treatment (P < 0.05) in all ROIs except for right medial temporal lobe-hippocampus and right inferior parietal lobule. Conclusion. Functional connectivity of the brain is changed in patients with FD but approximates that in healthy control after acupuncture treatment. The relief of gastrointestinal signs and symptoms by acupuncture is likely due to the normalization of brain-gut axis associated with FD.

Moxibustion and Acupuncture Ameliorate Crohn's Disease by Regulating the Balance between Th17 and Treg Cells in the Intestinal Mucosa. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 2015:938054.

Abstract
Previous studies have demonstrated that acupuncture is beneficial to patients with Crohn's disease (CD), but the mechanism underlying its therapeutic effects remains unclear. To identify the mechanism by which acupuncture treats CD, the balance between Th17 and Treg cells was assessed in CD patients. In this study, Ninety-two CD patients were randomly and equally assigned to a treatment group that were treated with herb-partitioned moxibustion and acupuncture or a control group with wheat bran-partitioned moxibustion and superficial acupuncture. The effect of these treatments on Th17 and Treg cells and their related molecular markers in the intestinal mucosa were detected before (week 0) and after (week 12) treatment. The results suggested that the ratio of Th17 and Treg cells was significantly decreased after treatment and that the levels of IL-17 and RORγt in the intestinal mucosa were obviously reduced, while the expression of FOXP3 was increased after treatment in both groups. In the treatment group, the expression of these molecules was more markedly regulated than the control group. In conclusion, moxibustion and acupuncture have been shown to regulate the ratio of Th17 and Treg cells in the intestinal mucosa of CD patients and restore the balance between these immune cell subsets.

Abstract
In order to investigate the therapeutic potential of acupuncture on patients with functional dyspepsia (FD), patients were randomized to receive acupuncture at classic acupoints with manipulations (treatment group) versus acupuncture at nonacupoints without manipulation (control group) once every other day, three times a week, for one month and were followed up for three months. The primary outcomes included dyspeptic symptoms, quality of life, and mental status. The secondary outcomes included the fasting serum gastrin concentration, and frequency and propagation velocity of gastric slow waves. Sixty patients with FD were included, among whom, four dropped out. After one month's treatment, patients with FD showed significant improvements in primary (in both groups) and secondary (in the eight patients of the treatment group) outcomes as compared with baseline (P = 0.0078 to <0.0001); treatment group has better outcomes in all primary outcome measures (P < 0.0001 except for SDS (P = 0.0005)). Improvements on dyspeptic symptoms persist during follow-up (better in the treatment group). Acupuncture with manual manipulation had better effects on improving dyspeptic symptoms, mental status, and quality of life in patients with FD. These effects may be related to the increased frequency and propagation speed of gastric slow waves and serum gastrin secretion.

Abstract
OBJECTIVES The use of acupuncture treatment (AT) for functional dyspepsia is increasing, particularly in Asia. However, the efficacy of AT and its side effects have not been assessed. We performed a systematic review and meta-analysis of studies related to the effectiveness of AT for functional dyspepsia. DESIGN This study is a systemic review and meta-analysis. Seven electronic databases, including those in the English and Chinese languages, were systematically searched for randomized controlled trials of AT for functional dyspepsia through November 2012. There were no language restrictions. SETTING Randomized controlled trials (RCT) AT compared with placebo control or a comparative intervention were considered. The methodological qualities of the studies were evaluated using the risk of bias (ROB). Subgroups were analyzed according to the kinds of controls. MAIN OUTCOME MEASURES The primary outcomes were symptom scores. These included visual analogue scale (VAS) and Nepean Dyspepsia Index (NDI). Secondary outcomes were the total effective rate and adverse effects. RESULTS Twenty studies, including 1423 individual cases, were systematically reviewed. The risk of bias was high. Compared to sham AT, AT was associated with a significant positive effect in patients with functional dyspepsia (2.66, 95% CI 1.85-3.82). AT also improved symptoms for functional dyspepsia (1.18, 95% CI 1.01-2.60) compared to GI tract regulators on total effective rate. In addition, two articles produced a scale in favor of AT compared to medication (0.54, 95% CI 0.18-0.90). Two RCTs reported minimal AT-related adverse events. CONCLUSIONS The evidence suggests that AT is effective for functional dyspepsia. However, well-planned, long-term studies are necessary to evaluate the efficacy of AT for functional dyspepsia.

Abstract
BACKGROUND Whether subgroups of functional dyspepsia (FD) should be treated with different approaches is controversially discussed in research. As our previous study has demonstrated the effect of acupuncture in FD treatment, we now further analyze the therapeutic effect of acupuncture in the treatment of postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). METHODS A retrospective analysis was conducted in 465 eligible PDS patients and 241 EPS patients. 4 acupuncture groups (group A: specific acupoints along the stomach meridian; group B: non-specific acupoints along the stomach meridian; group C: alarm and transport acupoints; group D: specific acupoints along the gallbladder meridian) were compared with a non-acupoint sham acupuncture group and an itopride group. The patients were treated in 5 consecutive sessions per week for 4 weeks and were followed-up for 12 weeks afterwards. Primary outcome of the study was defined as response rate and symptom improvement as measured by the Symptom Index of Dyspepsia, while secondary outcome was designated as improvement in quality of life (QoL) as determined by the Nepean Dyspepsia Index. RESULTS Symptoms of dyspepsia and QoL were improved from baseline in all groups. In EPS patients, no statistically significant differences could be observed in response rate (p = 0.239) and symptoms improvement (p = 0.344 for epigastric pain; p = 0.465 for epigastric burning). In contrast, PDS patients of the acupuncture group A showed higher response rate (53.2% vs. 19.7%, p<0.001; 53.2% vs. 35.1%, p = 0.025) and score change in postprandial fullness (1.01 vs. 0.27, p<0.001; 1.01 vs. 0.57, p<0.001), early satiation (0.81 vs. 0.21, p<0.001; 0.81 vs. 0.39, p=0.001), and QoL (14.5 vs. 4.33, p<0.001; 14.5 vs. 8.5, p<0.001) compared to the sham acupuncture and itopride group. CONCLUSIONS FD patients with PDS responded better to the acupuncture therapies, especially at the specific acupoints along the stomach meridian. The positive therapeutic effect of acupuncture on PDS was correlated with the improvement in postprandial fullness. TRIAL REGISTRATION ClinicalTrial.gov NCT00599677.

Abstract
General interest in functional gastrointestinal disorders is increasing among Japanese doctors as well as patients. This increase can be attributed to a number of factors, including recent increased interest in quality of life and advances in our understanding of the pathophysiology of gastrointestinal disease. Japan recently became the world's first country to list "functional dyspepsia" as a disease name for national insurance billing purposes. However, recognition and understanding of functional dyspepsia (FD) remain poor, and no standard treatment strategy has yet been established. Accordingly, the Japanese Society of Gastroenterology (JSGE) developed an evidence-based clinical practice guideline for FD, consisting of five sections: concept, definition, and epidemiology; pathophysiology; diagnosis; treatment; and prognosis and complications. This article summarizes the Japanese guideline, with particular focus on the treatment section. Once a patient is diagnosed with FD, the doctor should carefully explain the pathophysiology and benign nature of this condition, establish a good doctor-patient relationship, and then provide advice for daily living (diet and lifestyle modifications, explanations, and reassurance). The proposed pharmacological treatment is divided into two steps: initial treatment including an acid inhibitory drug (H2RA or PPI) or prokinetics, (strong recommendation); second-line treatment including anxiolytics, antidepressants, and Japanese traditional medicine (weak recommendation). H. pylori eradication, strongly recommended with a high evidence level, is positioned separately from other treatment flows. Conditions that do not respond to these treatment regimens are regarded as refractory FD. Patients will be further examined for other organic disorders or will be referred to specialists using other approaches such as psychosomatic treatment.

Abstract
BACKGROUND Functional dyspepsia (FD) has been a worldwide complaint. More effective therapies are needed with fewer adverse effects than are seen with conventional medications. Acupuncture, as a traditional therapeutic method, has been widely used for functional gastrointestinal disorders in the East. Manual acupuncture and electroacupuncture have been recognized treatments for FD, but to date, no robust evidence has been found for the effectiveness and safety of these interventions in the treatment of this condition. OBJECTIVES This review was conducted to assess the efficacy and safety of manual acupuncture and electroacupuncture in the treatment of FD. SEARCH METHODS Trials meeting the inclusion criteria were identified through electronic searches of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the Allied and Complementary Medicine Database (AMED), Chinese Biology Medicine Disc (CBMdisc), China National Knowledge Infrastructure (CNKI), the Wanfang Database, the VIP Database, and six trial registries. Handsearching was done to screen the reference sections of potential trials and reviews. SELECTION CRITERIA Randomized controlled trials (RCTs) were included if investigators reported efficacy and safety of manual acupuncture or electroacupuncture for patients with FD diagnosed by Rome II or Rome III criteria, compared with medications, blank control, or sham acupuncture. DATA COLLECTION AND ANALYSIS Data were extracted by independent review authors. Study limitations were assessed by using the tool of The Cochrane Collabration for assessing risk of bias. For dichotomous data, risk ratios (RRs) and 95% confidence intervals (95% CIs) would be applied, and for continuous data, mean differences (MDs) and 95% CIs. A fixed-effect model was applied in the meta-analysis, or a descriptive analysis was performed. The quality of evidence for the outcome measure was assessed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methods. MAIN RESULTS Seven studies were included in the review, involving 542 participants with FD (212 males and 330 females). These studies generally had an unclear risk of bias based on inadequate descriptions of allocation concealment and a high risk of bias based on lack of blinding. None of the studies reported on outcomes of the Functional Digestive Disorder Quality of Life questionnaire (FDDQL), the Satisfaction With Dyspepsia Related Health scale (SODA), the Digestive Health Status Instrument (DHSI), or effective/inefficient rate and symptom recurrence six months from completion of acupuncture treatment.Four RCTs of acupuncture versus medications (cisapride, domperidone, and itopride) were included in the review. No statistically significant difference was noted in the reduction in FD symptom scores and the frequency of FD attack by manual acupuncture, manual-electroacupuncture, or electroacupuncture compared with medications. In three trials of acupuncture versus sham acupuncture, all descriptive or quantitative analysis results implied that acupuncture could improve FD symptom scores and scores on the Neck Disability Index (NDI), the 36-Item Short Form Health Survey (SF-36), the Self-Rating Anxiety Scale (SAS), and the Self-Rating Depression Scale (SDS) more or as significantly as sham acupuncture. With regard to adverse effects, acupuncture was superior to cisapride treatment (one study; all minor events), but no statistically significant difference was reported between acupuncture and sham acupuncture. No adverse effects data were reported in studies examining manual acupuncture versus domperidone, manual-electroacupuncture versus domperidone, or electroacupuncture versus itopride.Nevertheless, all evidence was of low or very low quality. The body of evidence identified cannot yet permit a robust conclusion regarding the efficacy and safety of acupuncture for FD. AUTHORS' CONCLUSIONS It remains unknown whether manual acupuncture or electroacupuncture is more effective or safer than other treatments for patients with FD.

Stanghellini V, Cogliandro R. Review article: adherence to Rome criteria in therapeutic trials in functional dyspepsia. Aliment Pharmacol Ther 2014; 40:435-66. [PMID: 25056101 DOI: 10.1111/apt.12865] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2014] [Revised: 04/26/2014] [Accepted: 06/19/2014] [Indexed: 12/19/2022]
Abstract
BACKGROUND The Rome criteria are currently required by health authorities for the inclusion of patients affected by functional dyspepsia in therapeutic trials. However, the degree of adherence to these criteria has not been formally verified. AIM To review adherence to the Rome criteria for inclusion criteria, outcome measures and endpoints in therapeutic trials on functional dyspepsia and the potential impact on the conclusions that can be drawn from these studies. METHODS A total of 1818 articles were screened. Fifty-eight trials claiming to include adults affected by functional dyspepsia as defined by the Rome criteria published as full articles in English between 2000 and 2013 were considered. RESULTS Lack of full adherence to the Rome criteria of inclusion criteria was found in 54% of the studies, due to inclusion of patients with symptoms not reported in the Rome criteria or definitions of dyspeptic symptom that varied from those proposed by the Rome criteria. Ninety-five per cent of clinical trials adopted therapeutic outcome measures that were not adherent to the Rome criteria, using questionnaires that did not include all dyspeptic symptoms or including symptoms other than those proposed by the Rome criteria. CONCLUSIONS Stringent criteria have not been adopted for inclusion criteria and outcome measures in the vast majority of published studies on functional dyspepsia that claim to have been carried out according to the Rome criteria. Appropriate questionnaires should be developed to promote adherence to internationally accepted definitions of the syndrome in future studies.

Randomized controlled trial: Moxibustion and acupuncture for the treatment of Crohn’s disease. World J Gastroenterol 2014; 20:11000-11011. [PMID: 25152604 PMCID: PMC4138481 DOI: 10.3748/wjg.v20.i31.11000] [Citation(s) in RCA: 57] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2014] [Revised: 03/25/2014] [Accepted: 05/26/2014] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate the clinical efficacy and safety of acupuncture and moxibustion for the treatment of active Crohn’s disease (CD).
METHODS: Ninety-two patients were equally and randomly divided into the treatment group and received herb-partitioned moxibustion combined with acupuncture, and the control group received wheat bran-partitioned moxibustion combined with superficial acupuncture. The patients received three treatment sessions per week for 12 wk and were followed up for 24 wk. The main outcome was evaluated using the CD Activity Index (CDAI) score, and the secondary outcomes were evaluated using laboratory indicators such as hemoglobin (HGB), C-reactive protein (CRP), erythrocyte sedimentation rate, quality-of-life, endoscopic ratings, and intestinal histology scores.
RESULTS: The CDAI scores of both the treatment and control groups were significantly reduced after treatment compared with those measured before treatment. However, the degree of improvement in the treatment group was significantly greater than that of the control group. The improvement in symptoms in patients of the treatment group was sustained at follow-up, whereas that of the control group was not. The overall efficacy of the treatment was significantly greater than that of the control. Both groups demonstrated significant improvements in quality-of-life ratings after treatment, but the improvement was significantly greater in the treatment group than in the control group. In addition, the patients in the treatment group showed significantly increased HGB and significantly decreased CRP levels and histopathological scores at the end of treatment, whereas the control group did not exhibit significant changes.
CONCLUSION: Moxibustion with acupuncture provided significant therapeutic benefits in patients with active CD beyond the placebo effect and is therefore an effective and safe treatment for active CD.

Abstract
Background Functional dyspepsia (FD) is a common health problem currently without any optimal treatments. Acupuncture has been traditionally sought as a treatment for FD. The aim of this study is to investigate whether acupuncture treatment helps improve symptoms of FD. Methods/design A two-center, randomized, waitlist-controlled trial will be carried out to evaluate whether acupuncture treatment improves FD symptoms. Seventy six participants aged 18 to 75 years with FD as diagnosed by Rome III criteria will be recruited from August 2013 to January 2014 at two Korean Medicine hospitals. They will be randomly allocated either into eight sessions of partially individualized acupuncture treatment over 4 weeks or a waitlist group. The acupuncture group will then be followed-up for 3 weeks with six telephone visits and a final visit will be paid at 8 weeks. The waitlist group will receive the identical acupuncture treatment after a 4-week waiting period. The primary outcome is the proportion of responders with adequate symptom relief and the secondary outcomes include Nepean dyspepsia index, EQ-5D, FD-related quality of life, Beck’s depression inventory, state-trait anxiety inventory questionnaire, and level of ghrelin hormone. The protocol was approved by the participating centers’ Institutional Review Boards. Discussion Results of this trial will help clarify not only whether the acupuncture treatment is beneficial for symptom improvement in FD patients but also to elucidate the related mechanisms of how acupuncture might work. Trial registration ClinicalTrials.gov Identifier: NCT01921504.

Abstract
OBJECTIVES Acupuncture is a commonly used therapy for treating functional dyspepsia (FD), although the mechanism remains unclear. The objectives of this study were to investigate the differences in cerebral glycometabolism changes evoked by acupuncture and sham acupuncture and to explore the possible correlations between brain responses and clinical efficacy. METHODS In all, 72 FD patients were randomly assigned to receive either acupuncture or sham acupuncture treatment for 4 weeks. Ten patients in each group were randomly selected for fluorine-18 fluorodeoxyglucose positron emission tomography computed tomography scans to detect cerebral glycometabolism changes. The Nepean Dyspepsia Index (NDI) and Symptom Index of Dyspepsia (SID) were used to evaluate the therapeutic effect. RESULTS (i) The clinical data showed that after treatment the decrease in SID score in the acupuncture group was significantly greater than that in the sham acupuncture group (P<0.05). The increase in NDI score between the two groups did not differ (P>0.05), and only the improvement in NDI score in the acupuncture group was clinically significant. (ii) The neuroimaging data indicated that after treatment the acupuncture group showed extensive deactivation in cerebral activities compared with the sham acupuncture group. In the acupuncture group, the deactivations of the brainstem, anterior cingulate cortex (ACC), insula, thalamus, and hypothalamus were nearly all related to the decrease in SID score and the increase in NDI score (P<0.05, corrected). In the sham acupuncture group, the deactivations of the brainstem and thalamus tended to be associated with the increase in NDI score (P<0.1, corrected). CONCLUSIONS Acupuncture and sham acupuncture have relatively different clinical efficacy and brain responses. Acupuncture treatment more significantly improves the symptoms and quality of life of FD patients. The more remarkable modulation on the homeostatic afferent network, including the insula, ACC, and hypothalamus, might be the specific mechanism of acupuncture.

Abstract
Background. Acupoints (belonging to 12 meridians) which have the same names are symmetrically distributed on the body. It has been proved that acupoints have certain biological specificities different from the normal parts of the body. However, there is little evidence that acupoints which have the same name and are located bilaterally and symmetrically have lateralized specificity. Thus, researching the lateralized specificity and the relationship between left-side and right-side acupuncture is of special importance. Methodology and Principal Findings. The mean blood flux (MBF) in both Hegu acupoints was measured by Moor full-field laser perfusion imager. With the method of system identification algorithm, the output distribution in different groups was acquired, based on different acupoint stimulation and standard signal input. It is demonstrated that after stimulation of the right Hegu acupoint by needle, the output value of MBF in contralateral Hegu acupoint was strongly amplified, while after acupuncturing the left Hegu acupoint, the output value of MBF in either side Hegu acupoint was amplified moderately. Conclusions and Significance. This paper indicates that the Hegu acupoint has lateralized specificity. After stimulating the ipsilateral Hegu acupoint, symmetry breaking will be produced in contrast to contralateral Hegu acupoint stimulation.

Abstract
BACKGROUND Functional dyspepsia (FD) is a common disease without an established optimal treatment. AIM To determine (i) the effect of acupuncture in relieving FD symptoms and improving life quality; (ii) the effect difference between acupoint and non-acupoint; and (iii) the effect difference among different acupoints. METHODS A total of 712 eligible patients were included and randomly assigned to six groups (Group A: specific acupoints of the stomach meridian; Group B: non-specific acupoints of the stomach meridian; Group C: specific acupoints of alarm and transport points; Group D: specific acupoints of the gallbladder meridian; Group E: sham acupuncture of non-acupoints; and Group F: itopride). A treatment period of 4 weeks (continuous five sessions per week), and a follow-up period of 12 weeks were arranged. The outcomes were the (i) patients' response, (ii) symptoms improvement measured using the Symptom Index of Dyspepsia and (iii) quality-of-life improvement based on Nepean Dyspepsia Index. RESULTS All groups had an improvement in dyspepsia symptoms and the QoL at the end of treatment, and the improvement was sustained for 4 weeks and 12 weeks. The overall response rate was significantly higher in acupuncture group A (70.69%), and lower in sham acupuncture group (34.75%), compared with itopride and other acupuncture groups. Similarly, the difference in symptoms and QoL improvement was significant between group A and the other acupuncture groups. CONCLUSIONS Acupuncture is effective in the treatment of functional dyspepsia, and is superior to non-acupoint puncture. The benefit of acupuncture relies on acupoint specificity.

Abstract
OBJECTIVE Functional magnetic resonance imaging (fMRI), in combination with block design paradigms with consecutive acupuncture stimulations, has often been used to investigate the neural responses to acupuncture. In this study, we investigated whether previous acupuncture stimulations can affect brain activations of later acupuncture stimulations. DESIGN All subjects were measured twice in the same scanning session and a block design was used. SETTING The study was conducted at Kyung Hee University, Seoul, Republic of Korea. SUBJECTS Fifteen (15) healthy right-handed male volunteers participated in the study. INTERVENTION The subjects received two acupuncture stimulations on BL62 (Shenmai) on the right foot with a time interval of 5 minutes. In addition, sham stimulations were tested with the same paradigm. OUTCOME MEASURES One-sample t tests were conducted in order to map the brain activations induced by the acupuncture and sham stimulations. Moreover, paired-sample t tests were conducted to investigate the signal changes between the first and second acupuncture stimulation. RESULTS During the first acupuncture stimulation, in the left hemisphere, significant foci of activation were found in the hypothalamus, thalamus, claustrum, cerebellum, inferior frontal gyrus, and the superior temporal gyrus. In the right hemisphere, a significant focus of activation was found in the middle frontal gyrus. In addition, in both hemispheres, a significant focus of activation was found in the inferior parietal lobule. Interestingly, however, during the second acupuncture stimulation, the only areas that were also significantly activated were the cerebellum in the left hemisphere and the inferior parietal lobule in the right hemisphere. CONCLUSIONS We found that consecutive acupuncture stimulations on BL62 affected the neural responses in a significant way, resulting in decreased activations during the second acupuncture stimulation. This is an important finding, suggesting that in future fMRI studies on acupuncture, researchers should take this methodological issue more seriously.

Abstract
During the last decades, numerous studies have been performed to investigate the effects and mechanisms of acupuncture or electroacupuncture (EA) on gastrointestinal motility and patients with functional gastrointestinal diseases. A PubMed search was performed on this topic and all available studies published in English have been reviewed and evaluated. This review is organized based on the gastrointestinal organ (from the esophagus to the colon), components of gastrointestinal motility and the functional diseases related to specific motility disorders. It was found that the effects of acupuncture or EA on gastrointestinal motility were fairly consistent and the major acupuncture points used in these studies were ST36 and PC6. Gastric motility has been mostly studied, whereas much less information is available on the effect of EA on small and large intestinal motility or related disorders. A number of clinical studies have been published, investigating the therapeutic effects of EA on a number of functional gastrointestinal diseases, such as gastroesophageal reflux, functional dyspepsia and irritable bowel syndrome. However, the findings of these clinical studies were inconclusive. In summary, acupuncture or EA is able to alter gastrointestinal motility functions and improve gastrointestinal motility disorders. However, more studies are needed to establish the therapeutic roles of EA in treating functional gastrointestinal diseases.
