Acupuncture for irritable bowel syndrome: diagnosis and treatment of patients in a pragmatic trial

Association Between Acupoint Selection, Target Symptoms, and Traditional Chinese Medicine Diagnosis in Real-Time Clinical Practice in a Comprehensive Cancer Center

Background: Acupuncture intervention in actual practice is rarely reported and may be different from that applied in acupuncture research. Objectives: To review acupuncture practice in an integrative medicine clinic and characterize the association between targeted symptoms, traditional Chinese medicine (TCM) diagnosis, and acupoint selection. Methods: We reviewed outpatient acupuncture records from March 2016 to April 2018. Statistical analyses were applied to characterize referral symptoms and associated TCM diagnosis as well as acupoint selection. Results: The final analysis included 5393 acupuncture records (1264 patients). Twelve TCM diagnosis components were identified in the referral symptoms of pain, neuropathy, xerostomia, and hot flashes. Pain was associated with 78 different TCM diagnoses (combinations of TCM diagnosis components). Total of 217 different acupoints were used in the acupuncture treatments (1739) for neuropathy. The acupoint yintang was used in 73.8% of the visits for neuropathy, yet only in 26.5% (P < .001) of the treatments when patients had a TCM diagnosis of qi deficiency, qi stagnation, and blood stagnation. Similarly, both consistencies and variations were seen in acupoint selection with each targeted symptom and its associated TCM diagnoses. Conclusions: TCM diagnosis was not homogeneous among acupuncture treatments for a single referral symptom. In contrast to most of the research on acupuncture for symptom control, there were considerable variations in acupoint selection among treatments for the same symptom in a clinical setting. Future research is needed to examine the clinical relevance of a fixed intervention structure in acupuncture research and the value of individualized acupuncture treatment.

Augmentation of Cancer Cachexia Components With Targeted Acupuncture in Patients With Gastrointestinal Cancers: A Randomized Controlled Pilot Study

Introduction: Patients with gastrointestinal (GI) cancer-associated cachexia are at risk of high morbidity and mortality. This randomized single-blind pilot study compared the complementary use of targeted acupuncture (TA) with nontargeted acupuncture (NTA) for halting cachexia symptoms. Methods: GI cancer patients with cachexia undergoing chemotherapy were assigned to receive 8 weekly sessions of either TA (n = 15) or NTA (n = 15) following a specific acupuncture protocol. Bioelectrical impedance analysis and weight were measured weekly. Biological markers, including C-reactive protein, prealbumin, tumor necrosis factor-α, lactate dehydrogenase (LDH), leptin, and ghrelin blood levels were determined at specific intervals. Results: Prealbumin levels and fat-free mass were significantly higher in the NTA group at the end of the study, but remained stable in TA group. TA group had significantly lower (230 IU/L vs 288 IU/L, P = .04) LDH at the end of the study, but elevated tumor necrosis factor-α levels (13.15 pg/mL vs 9.24 pg/mL, P = .04). The absolute blood leptin and ghrelin levels decreased in the TA but remained stable in the NTA group. Both groups maintained weight, but the TA group trended toward weight gain during the last 2 weeks of the study. No adverse events related to acupuncture were reported. Conclusions: TA using predetermined, reproducible points may provide benefits to some patients with GI cancer cachexia by normalizing metabolic dysregulation. Elevated ghrelin levels are indicative of insulin resistance, which can lead to increased muscle loss represented by increased LDH activity in the NTA group. The pilot study provided completion rate and effect size for the primary outcome measures for a larger study. A longer treatment duration may be required to further refine these findings.

Zusanli (ST36) acupoint injection for acute diarrhea in children under 5 years old: A protocol of systematic review and meta-analysis of randomized clinical trials

BACKGROUND

Acute diarrhea is the 2nd highest prevalence disease among children under 5 years of age. It can cause malnutrition and even death in children, especially in developing country. Traditional Chinese medicine therapy has been applied and already in the guidelines for clinical practice of acute infectious diarrhea in children in China, but there is no specific methods or recommendations due to lacking of evidence. Zusanli acupoint injection as a form of acupuncture therapy, which is proved to be effective in randomised controlled trials (RCTs) and very suitable for children, has been used in acute diarrhea in children for a long time; therefore, a systematic review is necessary to provide available evidence for further study.

METHODS

Different studies from various databases will be involved in this study. Only RCTs of children under 5 years of age diagnosed with acute diarrhea using any recognized diagnostic criteria will be included. We will search manually the literature in the databases from China Conference Paper Database. Electronic database includes PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Internet, WanFang, Chongqing VIP, and China Biomedical Literature CDROM Database. Primary outcomes: clinical cure rate (clinical cure is defined as the frequency, timing and character of stool back to normal status, as well as disappearance of diarrhea symptoms), diarrhea duration (from admission to the cessation of diarrhea).

SECONDARY OUTCOMES

stool frequency within 24 hours, rate of adverse effect. Data will be extracted by 2 researchers independently; risk of bias of the meta-analysis will be evaluated based on the Cochrane Handbook for Systematic Reviews of Interventions. All data analysis will be conducted by data statistics software Review Manager V.5.3. and Stata V.12.0.

RESULTS

This study will synthesize and provide evidence based on the data of the currently published zusanli (ST36) acupoint injection for acute diarrhea in children under 5 years old, especially in terms of clinical efficacy and safety.

CONCLUSION

This systematic review aims to evaluate the benefits and harms of zusanli acupoint injection for acute diarrhea in children under 5 years old reported in RCTs, and provide evidence reference in TCM field for Chinese guidelines on the treatment of acute diarrhea in children.

ETHICS AND DISSEMINATION

This study is a systematic review; the outcomes are based on the published evidence, and hence examination and agreement by the ethics committee are not required in this study. We intend to publish the study results in a journal or conference presentations.

Lifestyle Advice and Self-Care Integral to Acupuncture Treatment for Patients with Chronic Neck Pain: Secondary Analysis of Outcomes Within a Randomized Controlled Trial

Background: Lifestyle advice is widely considered as an integral component of acupuncture treatment. However, it is unclear whether lifestyle advice and related self-care are important for sustaining benefit over the longer term. In a novel secondary analysis of trial data, this paper explores the nature and impact of acupuncture-related diagnosis, and associated lifestyle advice and self-care, in patients with chronic neck pain.

Design: In a three-arm, randomized, controlled multicenter trial with 12 months of follow-up, a total of 517 patients with chronic neck pain were randomized in equal proportions to acupuncture, Alexander technique, or usual care alone.

Methods: For each acupuncture patient, practitioners reported treatment components that included an acupuncture-related diagnosis and provision of associated lifestyle advice. Patients reported at baseline, 3, 6, and 12 months on variables related to treatment, which included aspects of self-care, self-efficacy, and lifestyle advice acted upon, as well as pain and disability scores. Congruence between practitioner advice and patient take-up was assessed using chi-squared test. Impact of lifestyle advice and self-efficacy on outcome was evaluated using regression models.

Results: Among patients randomized to acupuncture, the most common diagnostic framework involved the Zang–Fu syndromes for 139/160 (87%) patients. Lifestyle advice was provided by practitioners to 134/160 (84%) of patients, most commonly related to exercise, relaxation, diet, rest, and work. Significant congruence with patient take-up was found for diet, rest, and work. Moreover, patients in the acupuncture group improved their ability to use what they had learnt and increased their self-efficacy. In turn, these characteristics were associated with significant reductions in pain and disability scores at 12 months.

Conclusion: Acupuncture-related lifestyle advice helped patients improve the way they live and care for themselves and enhanced self-efficacy and ability to use what they had learnt. These changes were associated with reductions in pain and disability at 12 months.

Zeta Inhibitory Peptide as a Novel Therapy to Control Chronic Visceral Hypersensitivity in a Rat Model

Background

The pathogenesis of multiple chronic visceral pain syndromes, such as irritable bowel syndrome (IBS), is not well known, and as a result current therapies are ineffective. The objective of this study was to investigate the effect of spinal protein kinase M zeta (PKMζ) on visceral pain sensitivity in rats with IBS to better understand the pathogenesis and investigate the effect of zeta inhibitory peptide (ZIP) as a therapy for chronic visceral pain.

Methods

Visceral hypersensitivity rats were produced by neonatal maternal separation (NMS). Visceral pain sensitivity was assessed by electromyographic (EMG) responses of abdominal muscles to colorectal distention (CRD). Spinal PKMζ and phosphorylated PKMζ (p-PKMζ) were detected by western blot. Varying doses of ZIP were intrathecally administered to investigate the role of spinal PKMζ in chronic visceral hypersensitivity. The open field test was used to determine if ZIP therapy causes spontaneous motor activity side effects.

Results

Graded CRD pressure significantly increased EMG responses in NMS rats compared to control rats (p < 0.05). p-PKMζ expression increased in the thoracolumbar and lumbosacral spinal cord in the IBS-like rats with notable concomitant chronic visceral pain compared to control rats (p < 0.05). EMG data revealed that intrathecal ZIP injection (1, 5, and 10 μg) dose-dependently attenuated visceral pain hypersensitivity in IBS-like rats.

Conclusions

Phosphorylated PKMζ may be involved in the spinal central sensitization of chronic visceral hypersensitivity in IBS, and administration of ZIP could effectively treat chronic visceral pain with good outcomes in rat models.

Acupuncture-Related Quality of Life Changes Using PROMIS Computer Adaptive Tests in a Pragmatic Trial with Oncology and General Integrative Medicine Patients: The Role of Baseline Acupuncture Expectations

INTRODUCTION

Acupuncture has been shown to alleviate symptoms and increase general well-being in different medical patient samples. A major challenge in acupuncture clinical research is the availability of comparable and standardized patient-reported outcome measurement (PRO) tools.

OBJECTIVES

This study used a pragmatic design to examine longitudinal changes in quality of life (QOL) in a medical patient sample following acupuncture using PROs from the National Institutes of Health's Patient Reported Outcomes Measurement Information System (PROMIS) initiative. It also examined the role of acupuncture expectancies, as well as patient and provider perceptions of acupuncture benefit.

DESIGN

Following informed consent, patients completed baseline QOL measures (T1) prior to their first acupuncture session. Subsequent assessments (up to 20) were completed immediately following ensuing acupuncture sessions. Patients completed assessments either on a touch-screen computer at the clinic or from their home computer.

RESULTS

Compared with acupuncture-naïve participants, those who received prior acupuncture treatment reported significantly higher anxiety, fatigue, sleep disturbance, and lower positive affect at baseline. By the second assessment, however, these differences became nonexistent. Participants who held greater baseline acupuncture expectations (e.g., their situation would improve a lot, they would have improved coping skills, their symptoms would disappear, their energy would increase) reported significantly higher fatigue, pain interference, and problems with physical functioning. Between T1 and T2, all participants reported significant improvements in anxiety, depression, and fatigue. Exploratory longitudinal models demonstrated significant linear improvements over time in anxiety (p = 0.006), depression (p = 0.007), pain interference (p < 0.001), and sleep disturbance (p = 0.004). No linear reduction over time was found with fatigue (p = 0.587), physical function (p = 0.654), or positive affect (p = 0.247).

CONCLUSIONS

Overall, PROMIS computer adaptive tests were able to assess domains of QOL briefly. Although pretreatment acupuncture expectations highlighted subgroup differences in outcomes at baseline, linear-growth models demonstrated the positive effects of acupuncture over time on anxiety, depression, pain interference, and sleep disturbance.

Electroacupuncture for patients with diarrhea-predominant irritable bowel syndrome or functional diarrhea: A randomized controlled trial

Diarrhea-predominant irritable bowel syndrome (IBS-D) and functional diarrhea (FD) are highly prevalent, and the effectiveness of acupuncture for managing IBS-D and FD is still unknown.The aim of this study was to compare the effectiveness of electroacupuncture with loperamide.It was a prospective, randomized, parallel group controlled trial.A total of 448 participants were randomly assigned to He electroacupuncture group (n = 113), Shu-Mu electroacupuncture group (n = 111), He-Shu-Mu electroacupuncture group (n = 112), or loperamide group (n = 112). Participants in the 3 acupuncture groups received 16 sessions of electroacupuncture during a 4-week treatment phase, whereas participants in the loperamide group received oral loperamide 2 mg thrice daily. The primary outcome was the change from baseline in stool frequency at the end of the 4-weeks treatment. The secondary outcomes were the Bristol scale, the MOS 36-item short form health survey (SF-36), the weekly average number of days with normal defecations and the proportion of adverse events.Stool frequency was significantly reduced at the end of the 4-week treatment in the 4 groups (mean change from baseline, 5.35 times/week). No significant difference was found between the 3 electroacupuncture groups and the loperamide group in the primary outcome (He vs. loperamide group [mean difference 0.6, 95% CI, -1.2 to 2.4]; Shu-Mu vs. loperamide group [0.4, 95% CI, -1.4 to 2.3]; He-Shu-Mu vs. loperamide group [0.0, 95% CI, -1.8 to 1.8]). Both electroacupuncture and loperamide significantly improved the mean score of Bristol scale and increased the weekly average number of days with normal defecations and the mean scores of SF-36; they were equivalent in these outcomes. However, the participants in electroacupuncture groups did not report fewer adverse events than those in the loperamide group. Similar results were found in a subgroup analysis of separating patients with IBS-D and FD patients.Electroacupuncture is equivalent to loperamide for reducing stool frequency in IBS-D and FD patients. Further studies on cost effectiveness of acupuncture are warranted.

Effect of acupuncture and its influence on cerebral activity in functional dyspepsia patients: study protocol for a randomized controlled trial

BACKGROUND

Functional dyspepsia (FD) is a prevalent gastric disorder that is difficult to manage due to lack of satisfactory treatments. Acupuncture has been studied with regard to the rising need for treating FD, but the mechanism verifying its efficacy has not yet been fully revealed. The aim of this study is to explore the efficacy and mechanism of acupuncture for FD compared with a sham group.

METHODS/DESIGN

We describe a proposal for a randomized, assessor-blind, sham-controlled trial with 70 eligible participants who will be randomly allocated either into an acupuncture or a sham group. Participants in the acupuncture group will receive 10 sessions of real acupuncture treatment and those in the sham group will be treated with identical sessions using a Streitberger needle. Functional magnetic resonance imaging (fMRI) and metabolomics studies will be implemented before and after 4 weeks of treatment to investigate the mechanism of acupuncture. The primary outcome is a proportion of responders with adequate symptom relief and the secondary outcomes include the Nepean Dyspepsia Index - Korean version, Functional Dyspepsia-Related Quality of Life questionnaire, Ways of Coping Questionnaire, Coping Strategies Questionnaire, perception of bodily sensation questionnaire, State-Trait Anxiety Inventory, and the Center for Epidemiological Studies - Depression Scale. The outcomes will be evaluated before and after the treatment.

DISCUSSION

This is the first large-scale trial evaluating the efficacy and mechanism of acupuncture with fMRI and metabolomic methods. We will compare real acupuncture with the Streitberger sham needle to verify the specific effect of acupuncture. The results of this trial are expected to be relevant evidences affecting policy and decision-makers associated with routine healthcare.

Acupuncture for irritable bowel syndrome: 2-year follow-up of a randomised controlled trial

Background

A recent randomised controlled trial (RCT) of acupuncture as a treatment for irritable bowel syndrome (IBS) demonstrated sustained benefits over a period of 12 months post-randomisation.

Aim

To extend the trial follow-up to evaluate the effects of acupuncture at 24 months post-randomisation.

Methods

Patients in primary care with ongoing IBS were recruited to a two-arm pragmatic RCT of acupuncture for IBS. Participants were randomised to the offer of up to 10 weekly sessions of acupuncture plus usual care (n=116 patients) or to continue with usual care alone (n=117). The primary outcome was the self-reported IBS symptom severity score (IBS SSS) measured at 24 months post-randomisation. Analysis was by intention-to-treat using an unstructured multivariate linear model incorporating all repeated measures.

Results

The overall response rate was 61%. The adjusted difference in mean IBS SSS at 24 months was −18.28 (95% CI −40.95 to 4.40) in favour of the acupuncture arm. Differences at earlier time points estimated from the multivariate model were: −27.27 (−47.69 to −6.86) at 3 months; −23.69 (−45.17 to −2.21) at 6 months; −24.09 (−45.59 to −2.59) at 9 months; and −23.06 (−44.52 to −1.59) at 12 months.

Conclusions

There were no statistically significant differences between the acupuncture and usual care groups in IBS SSS at 24 months post-randomisation, and the point estimate for the mean difference was approximately 80% of the size of the statistically significant results seen at 6, 9 and 12 months.

Multicultural Aspects in Functional Gastrointestinal Disorders (FGIDs)

Cross-cultural factors are important in functional gastrointestinal disorders (FGIDs). In the setting of FGIDs, the aims of this review were to: 1) engender interest in global aspects; 2) gain a clearer understanding of culture, race and ethnicity and their effect on patient care and research; 3) facilitate cross-cultural clinical and research competency; and 4) improve and foster the quality and conduct of cross-cultural, multinational research. Cultural variables are inevitably present in the physician-patient context. Food and diets, which differ among cultural groups, are perceived globally as related to or blamed for symptoms. From an individual perspective, biological aspects, such as genetics, the microbiome, environmental hygiene, cytokines and the nervous system, which are affected by cultural differences, are all relevant. Of equal importance are issues related to gender, symptom reporting and interpretation, and family systems. From the physician's viewpoint, understanding the patient's explanatory model of illness, especially in a cultural context, affects patient care and patient education in a multicultural environment. Differences in the definition and use of Complementary and Alternative Medicine and other issues related to healthcare services for the FGIDs are also a relevant cross-cultural issue. This paper highlights the importance of cross-cultural competence in clinical medicine and research.

Mixed Methods in CAM Research: A Systematic Review of Studies Published in 2012

Background. Mixed methods research uses qualitative and quantitative methods together in a single study or a series of related studies. Objectives. To review the prevalence and quality of mixed methods studies in complementary medicine. Methods. All studies published in the top 10 integrative and complementary medicine journals in 2012 were screened. The quality of mixed methods studies was appraised using a published tool designed for mixed methods studies. Results. 4% of papers (95 out of 2349) reported mixed methods studies, 80 of which met criteria for applying the quality appraisal tool. The most popular formal mixed methods design was triangulation (used by 74% of studies), followed by embedded (14%), sequential explanatory (8%), and finally sequential exploratory (5%). Quantitative components were generally of higher quality than qualitative components; when quantitative components involved RCTs they were of particularly high quality. Common methodological limitations were identified. Most strikingly, none of the 80 mixed methods studies addressed the philosophical tensions inherent in mixing qualitative and quantitative methods. Conclusions and Implications. The quality of mixed methods research in CAM can be enhanced by addressing philosophical tensions and improving reporting of (a) analytic methods and reflexivity (in qualitative components) and (b) sampling and recruitment-related procedures (in all components).

Multivariate Analysis as a Method for Evaluating the Conceptual Perceptions of Korean Medicine Students regarding Phlegm Pattern

Individuals may perceive the concepts in Korean medicine pattern classification differently because it is performed according to the integration of a variety of information. Therefore, analysis about individual perspective is very important for examining the cross-sectional perspective state of Korean medicine concepts and developing both the clinical guideline including diagnosis and the curriculum of Korean medicine colleges. Moreover, because this conceptual difference is thought to begin with college education, it is worthwhile to observe students’ viewpoints. So, we suggested multivariate analysis to explore the dimensional structure of Korean medicine students’ conceptual perceptions regarding phlegm pattern. We surveyed 326 students divided into 5 groups based on their year of study. Data were analyzed using multidimensional scaling and factor analysis. Within-group difference was the smallest for third-year students, who have received Korean medicine education in full for the first time. With the exception of first-year students, the conceptual map revealed that each group’s mean perceptions of phlegm pattern were distributed in almost linear fashion. To determine the effect of education, we investigated the preference rankings and scores of each symptom. We also extracted factors to identify latent variables and to compare the between-group conceptual characteristics regarding phlegm pattern.

Acupuncture for irritable bowel syndrome: primary care based pragmatic randomised controlled trial

Background

Acupuncture is used by patients as a treatment for irritable bowel syndrome (IBS) but the evidence on effectiveness is limited. The purpose of the study was to evaluate the effectiveness of acupuncture for irritable bowel syndrome in primary care when provided as an adjunct to usual care.

Methods

Design: A two-arm pragmatic randomised controlled trial.

Setting: Primary care in the United Kingdom.

Patients: 233 patients had irritable bowel syndrome with average duration of 13 years and score of at least 100 on the IBS Symptom Severity Score (SSS).

Interventions: 116 patients were offered 10 weekly individualised acupuncture sessions plus usual care, 117 patients continued with usual care alone.

Measurements: Primary outcome was the IBS SSS at three months, with outcome data collected every three months to 12 months.

Results

There was a statistically significant difference between groups at three months favouring acupuncture with a reduction in IBS Symptom Severity Score of −27.43 (95% CI: –48.66 to −6.21, p = 0.012). The number needed to treat for successful treatment (≥50 point reduction in the IBS SSS) was six (95% CI: 3 to 17), based on 49% success in the acupuncture group vs. 31% in the control group, a difference between groups of 18% (95% CI: 6% to 31%). This benefit largely persisted at 6, 9 and 12 months.

Conclusions

Acupuncture for irritable bowel syndrome provided an additional benefit over usual care alone. The magnitude of the effect was sustained over the longer term. Acupuncture should be considered as a treatment option to be offered in primary care alongside other evidenced based treatments.
