Acupuncture plus moxibustion for herpes zoster: A systematic review and meta-analysis of randomized controlled trials

Research trends of acupuncture therapy for painful peripheral nervous system diseases from 2004 to 2023: a bibliometric and meta-analysis

Background

Peripheral nervous system diseases (PNSD) have represented a major global health burden, leading to significant economic impacts and diminished productivity. This bibliometric analysis was performed to summarize the current research trends and hotspots over the past two decades, aiming to provide a comprehensive perspective for future research.

Methods

All data were sourced from the Web of Science Core Collection (WoSCC) on March 1, 2024, for publications between January 1, 2004, and December 31, 2023. Data visualization and analyses, including descriptive statistics, co-occurrence mapping, and cluster analysis, were performed using CiteSpace (Version 6.1.R6) and Excel 2021.

Results

Our search yielded 678 references, with the annual publication count demonstrating an increasing trend over the past 20 years. The most productive country and institution were China and Kyung Hee University, respectively. Fang Jianqiao, was the most prolific author with the highest publications. Among journals, "Pain," was the most frequently cited, while the top-cited reference was a randomized controlled pilot trial by Lu Weidong in 2020. "Acupuncture" emerged as the keyword with the highest frequency. The meta-analysis indicated that acupuncture was more effective than standard care for pain associated with Diabetic Peripheral Neuropathy [MD = -2.03, 95% CI (-2.86, -1.21), 2 RCTs, 102 participants, p < 0.0001].

Conclusion

Our bibliometric review revealed key insights into the focal areas of PNSD research, underscoring the urgent need for continued and targeted high-quality investigations.

Efficacy and safety of therapies related to acupuncture for acute herpes zoster: A PRISMA systematic review and network meta-analysis

BACKGROUND

Herpes zoster (HZ) is mainly characterized by intense pain and severe skin lesions, particularly during the acute phase, which seriously affects the patient's quality of life. Acupuncture is a widely used and effective treatment for HZ. However, there are many types of acupuncture, which have different curative efficacy. This study employed a network meta-analysis (NMA) to assess and rank the clinical efficacy of different acupuncture therapies.

METHODS

The database of Cochrane Library, Web of Science, PubMed, MEDLINE, Embase, China National Knowledge Infrastructure (CNKI), Chinese BioMedical Database, VIP Database, and Wanfang Database were searched from inception to December 31, 2022 to identify eligible randomized controlled trials (RCTs) of acupuncture related therapies in the treatment of acute HZ. The outcome indicators measured were visual analogue scale (VAS), date of cessation of herpes increase (DCHI), effective rate (ER), postherpetic neuralgia (PHN), and adverse events (AEs). Bayesian network meta-analyses were performed using the GeMTC package (version 1.0-1) and R software (version 4.2.3).

RESULTS

A total of 59 RCTs with 3930 patients were included. The results of this NMA were as follows: compared with pharmacotherapy, electroacupuncture (EA) + pricking and cupping (PC) shown the best efficacy to improve VAS score and reduce DCHI. In terms of ER, EA + fire needle (FN) had the highest results of probability ranking. PC was more effective in reducing the incidence of PHN. Furthermore, this study shown that the incidence of AEs associated with acupuncture-related therapies was acceptable.

CONCLUSIONS

This study indicated that therapies related to acupuncture were both effective and safe in treating acute HZ, and could significantly reduce patients' symptoms such as pain and skin lesions with fewer adverse events. Clinically, the selection of the appropriate therapy should be based on practical considerations. However, due to the limitations of this study, more high-quality trials are required to evaluate the efficacy and safety of acupuncture-related therapy for the treatment of acute HZ.

Comparison of efficacy of acupuncture-related therapy in the treatment of herpes zoster: A network meta-analysis of randomized controlled trials

OBJECTIVE

A systematic review and meta-analysis of randomized controlled trials (RCTs) were conducted to evaluate the efficacy and safety of acupuncture-related therapy in the treatment of herpes zoster (HZ) and to provide a reference for the clinical treatment of herpes zoster.

METHODS

PubMed, Cochrane Library, EMBASE, Web of Science, CNKI, VIP database, Wanfang Database, and SinoMED Chinese and English databases were systematically searched for RCTs on acupuncture-related therapy for HZ until February 2023. Literature screening, data extraction, and risk of bias assessment were performed independently by 2 researchers. R4.2.1 and Stata15.1 software were used for data analysis.

RESULTS

A total of 26 RCTs involving 1929 HZ patients were included, and the network meta-analysis results showed that acupotomy appeared to be most effective in terms of improving VAS scores and the time of incrustation; SUCRA cumulative probability ranking showed the best efficacy of bloodletting in improving efficiency and the time of ceasing new blisters, acupuncture in improving the time of decrustation, and moxibustion in reducing the incidence of postherpetic neuralgia (PHN).

CONCLUSIONS

Through a comprehensive comparison of 9 different acupuncture therapies, acupotomy was the optimal treatment to improve VAS pain scores and the time of incrustation; bloodletting, acupuncture, fire needle, and moxibustion could be effective intervention measures to improve the time of ceasing new blisters and decrustation and reduce the incidence of PHN; Western medicine was closely related to adverse reactions. The conclusions need to be further verified due to the limitations of the study.

Similarities and differences between kaiy in Persian medicine and moxibustion in Chinese medicine

Kaiy (medieval cautery) is an ancient method of heat therapy in traditional Persian medicine (TPM). Some of its important applications have been neglected during the medical revolution. Meanwhile, different treatment modalities that incorporate heat, including moxibustion, have progressed in traditional Chinese medicine. In this study, we reviewed the main TPM textbooks that were written specifically in the field of kaiy. We considered the traditional teachings in the context of contemporary information, gathered from the scientific literature about moxibustion and modern cauterization. Some surgical therapeutic indications of kaiy (e.g., debridement and coagulative procedures) have been advanced by the innovation of electro-cauterization. However, those therapeutic applications that were based on the TPM humoral theory for relieving body coldness or myofascial pains-which are similar to moxibustion usages-have not received the same attention. Apart from the broad similarities of kaiy and moxibustion as thermal therapies with similar indications, there is a striking correspondence between kaiy point mapping and acupoints. Therefore, further research on different kaiy aspects is recommended. Please cite this article as: Jaladat AM, Alizadeh Vaghasloo M, Atarzadeh F, Ayati MH, Kazemi AH, Akin E, Hashempur MH.

Fire Needling Acupuncture for Adult Patients with Acute Herpes Zoster: Protocol of a Systematic Review and Meta-Analysis

Background

Acute herpes zoster (HZ) is characterized as a vesicular rash with unilateral distribution produced by the reactivation of varicella zoster virus. It can induce various comorbidities that can adversely influence the quality of life of patients. The purpose of this systematic review is to assess the effect and safety of fire needling acupuncture on acute HZ.

Methods

Three English databases (PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials) and four Chinese Databases (China National Knowledge Infrastructure, Wanfang database, Chongqing VIP database, and China Biology Medicine database) will be searched from their inceptions to July 2022. Randomized controlled trials investigating fire needling acupuncture therapy for acute HZ will be included, regardless of publication status. Two reviewers will independently conduct the study screening, data extraction, and research quality assessments. The primary outcome measures are the Pain Visual Analogue Scale and the occurrence of postherpetic neuralgia. Secondary outcomes measures are the evaluation of skin lesions, time to resolution of pain, tolerance evaluation, total effective rate, adverse events and changes in inflammatory and immune suppression markers in peripheral plasma. All included studies will be assessed for methodological quality via the Cochrane Collaboration’s bias risk assessment tool. Meta-analyses will be undertaken using Review Manager V.5.3 software. The findings will be reported as the risk ratio of the binary data and the mean difference (MD) or standardized MD of the continuous data. Subgroup analyses and sensitivity analyses will be conducted where appropriate. The Grading of Recommendations Assessment, Development, and Evaluation will be used to assess evidence certainty.

Results

From the study, we will ascertain the effects and safety of fire needling acupuncture on acute HZ.

Conclusion

This study will validate the effects and safety of fire needling acupuncture in the management of acute HZ, generating new evidence to guide acupuncture interventions for acute HZ in the future.

External Therapy of Chinese Medicine for Herpes Zoster: A Systematic Review and Meta-Analysis

Background. Herpes zoster (HZ) is a common skin disease that has a huge impact on the quality of life of sufferers. Antiviral therapy is a conventional treatment, but it still has limitations. This review evaluates the safety and efficacy of acupuncture in the treatment of HZ. Methods. We identified randomized controlled trials from multiple electronic sources (including Embase, PubMed, Cochrane, Web of Knowledge, China National Knowledge Infrastructure (CNKI), and China Biology Medicine Disc (CBM)) and reference lists of relevant articles and extracted data and assessed risk of bias (Cochrane’s Risk of Bias tool). Pooled data are expressed as standardized mean differences (SMDs), with 95% confidence intervals (CI) (random-effects model). Results. We included 15 trials (1811 participants) comparing acupuncture to medicine. Ten studies involving 1424 patients provided these data for the meta-analysis. The results showed that acupuncture as a control group had a higher clinical cure rate than Western medicine therapy (n = 1424, 95% Cl 2.19–3.14, I2 = 0%). Eleven studies used the visual analog scale (VAS), but only nine provided specific data, which we used as a continuous variable for data extraction. The meta-analysis also showed an SMD of −2.64 (n = 646, 95% CI −3.79–1.48, I2 = 97%) which showed great heterogeneity. Meta-analysis showed a significant reduction in the incidence of PHN in those who received acupuncture compared to pharmacotherapy (OR = 0.35, 95% CI 0.04–2.86, I2 = 52%) which showed moderate heterogeneity. Economic indicators suggest that acupuncture costs less and has fewer adverse reactions. Conclusions. This review compares acupuncture therapy with conventional treatment and finds that the curative effects of acupuncture are exact, with fewer side effects. However, with the risk of bias and imprecision of the studies included, a concrete conclusion is difficult to draw. Thus, well-designed, rigorous studies are warranted in the future.

Traditional Chinese Medicine for HIV-Associated Acute Herpes Zoster: A Systematic Review and Meta-Analysis of Randomized Trials

BACKGROUND

Herpes zoster (HZ) is a common infection in individuals with acquired immunodeficiency syndrome (AIDS) patients. Traditional Chinese medicine (TCM) has been used widely in clinical practice for HZ, which remains not supportive of evidence. This review aimed to evaluate the effectiveness and safety of TCM in treating HIV-associated HZ.

METHODS

Nine electronic databases were searched for randomized controlled trials (RCTs) testing TCM in treating HIV-associated HZ. Data were extracted on citations, interventions, and outcomes, by two authors independently. For the quality evaluation, Cochrane risk-of-bias tool 2.0 was used. Meta-analyses were performed by Revman5.3 software. Effect estimation presented as risk ratio (RR) for dichotomous data and mean difference (MD) for continuous data with their 95% confidence interval (CI).

RESULTS

Twelve RCTs (n = 644) were included; the majority of them had a high or unclear risk of bias. Meta-analysis showed that pain intensity (VAS 0-5) in the Chinese herbal medicine (CHM) group was lower than it in the drugs group (MD = -0.87, 95% CI [-1.69, -0.04], two trials, n = 93). Duration of herpes-related pain (days) of patients in the combination group was shorter than those in the drugs group (MD = -9.19, 95% CI [-16.73, -1.65], n = 144). The incidence of postherpetic neuralgia (PHN) in the combination group was lower than in the drugs group (RR = 0.49, 95% CI [0.25, 0.99], n = 202). As for cure rate (complete absence of pain and herpes), two trials showed that CHM was better than drugs (RR = 1.58, 95% CI [1.13, 2.22], n = 93), five trials showed combination treatment was better than drugs (RR = 1.40, 95% CI [1.08, 1.82], n = 224). The cure rate in the acupuncture group was more than that in the drugs group (RR = 1.99, 95% CI [1.18, 3.36], n = 120). Four trials reported adverse effects and found no serious adverse events occurred.

CONCLUSION

CHM and acupuncture demonstrate more benefits than drugs in pain relief, cure rate improvement, and incidence reduction of PHN. However, given the data limitation and TCM therapies' diversity, the conclusions need to be verified in future trials.

Analgesic Effect of Electroacupuncture on Postherpetic Neuralgia: A Trial Protocol for a Multicenter Randomized Controlled Trial

INTRODUCTION

The chronic neuropathic pain associated with postherpetic neuralgia (PHN) can last for several months or even many years, seriously affecting the affected person's work, sleep, mood, and daily life activities. In generaly, current treatments for PHN are at best limited and unsatisfactory, and adverse reactions are common, especially in elderly patients. Electroacupuncture (EA) is widely used clinically to manage painful diseases, but there remains a lack of evidence to support the effectiveness of EA on PHN. This study is designed to assess the efficacy and safety of EA on PHN, and to provide evidence-based medical evidence for EA treatment of PHN.

METHODS

This multicenter, prospective, randomized controlled trial will recruit 448 patients with PHN at seven clinical centers. Multicenter stratified variable block randomization will be used, and the eligible patients will be randomly allocated in a ratio of 1:1 to the EA group or sham EA group. The EA group will receive 4 weeks of EA treatment, given as 30-min treatment sessions, once daily, 5 times per week, for a total of 20 treatments; the sham EA group will receive sham EA treatment under the same conditions.

PLANNED OUTCOMES

The primary outcome measure is the 11-point Numeric Rating Scale pain score at week 4. The secondary outcome measures, including mechanical pain threshold, pain area of PHN, average number of pain episodes, the short-form McGill Pain Questionnaire 2, Zoster Brief Pain Inventory, the Depression, Anxiety, and Positive Outlook Scale, Patient Global Impression of Change, safety of EA, and use of concomitant medications, among others. The primary analysis of the outcomes will be the mixed-effect model with repeated measurement between groups on an intent-to-treat population.

Efficacy of Acupuncture for Herpes Zoster: A Systematic Review and Meta-Analysis

INTRODUCTION

This study aimed to assess the efficacy of acupuncture in patients with herpes zoster (HZ) based on current randomized clinical trials (RCTs).

METHODS

Five databases were screened for RCTs published until August 2019. Studies that assessed the efficacy of acupuncture when used as an independent intervention for HZ were included. The outcomes of interest were pain intensity, as assessed using the visual analog scale (VAS), incrustation time, decrustation time, and incidence of post-herpetic neuralgia (PHN).

RESULTS

In total, 21 RCTs were included in this research. Compared with antiviral therapy, acupuncture was associated with a reduction in VAS score by 16.13, incrustation time by 1.86 days, decrustation time by 2.19 days, and incidence of PHN by 83%. According to a meta-regression analysis, the main sources of heterogeneity were sample size and duration of treatment. There was no publication bias except on decrustation time. A sensitivity analysis showed that the outcomes were relatively stable and reliable.

CONCLUSION

Acupuncture may be effective for patients with HZ. Nevertheless, this finding should be validated by conducting high-quality trials with a larger sample size.

Efficacy and safety of acupuncture and moxibustion for herpes zoster: A protocol for systematic review and network meta analysis

INTRODUCTION

Herpes zoster (HZ) is currently treated primarily with antiviral drugs, yet this treatment has been debated. Acupuncture is becoming a more important treatment in this protocol. For example, pain intensity is lower among HZ patients who receive acupuncture plus moxibustion than among those who receive pharmacotherapy. There are many types of acupuncture interventions, including electroacupuncture, moxibustion, bloodletting. In this study, a network meta-analysis (NMA) is used to rank various interventions of acupuncture.

METHODS AND ANALYSIS

Electronic searches of abstracts and titles will be performed in MEDLINE, EMBASE, CENTRAL, CBM, CNKI, CQVIP, and Wanfang Data databases, from inception to December 31, 2019. Published and unpublished controlled trials with different acupuncture interventions will be selected, trials of antiviral drugs as the control group. All patients of HZ will be included, except for those diagnosed with PHN, immunocompromised patients, or those with complications. The effective therapy rate and the incidence of PHN are primary outcomes. The NMA will be analyzed with Stata 13.0 and GeMTC 0.14.3.

DISCUSSION

The NMA will be established to compare various interventions of acupuncture for the therapy of HZ, that could resolve the limitations of previous methodologies with this protocol. It will be possible to determine the best acupuncture intervention for more primary outcomes of therapy, including subgroup analysis of patients with aged ≥50 years and those of aged <50 years.

ETHICS AND DISSEMINATION

The NMA does not require ethical approval. The data analyzed is not personal. It is only systematically used to evaluate the effectiveness of acupuncture treatments. The results will be disseminated through international conference reports and peer-reviewed manuscripts.

STRENGTH AND LIMITATIONS OF THIS STUDY

A comprehensive methodology is established to rank various interventions of acupuncture by which best evidence-based intervention may be recommended for those population groups of aged ≥50 years and aged <50 years.

Fire needle plus cupping for acute herpes zoster: study protocol for a randomized controlled trial

Background

Acute herpes zoster (AHZ) is a common skin disease caused by invasion of the varicella zoster virus into the ganglia and skin, and the severe pain is the most complaint, which can seriously disturb the normal life of patients. Fire needle plus cupping is a special acupuncture treatment, which is widely used to treat AHZ for its better analgesic effect in China although it has not been fully verified by rigorous randomized controlled trial (RCT).

Methods/design

To test the effect, a three-arm randomized parallel controlled trial protocol has been designed. A total of 105 AHZ patients suffering pain will be randomly divided into three groups in an equal proportion. The interventions are fire needle plus cupping (FC) in group A, famciclovir plus gabapentin (FG) in group B, and fire needle plus cupping plus famciclovir (FCF) in group C. The length for the trial is set for a week time frame. Precisely speaking, the A group (FC) is to carry out 1 treatment per day for the total of 7 treatment sessions within 1 week period. On the other hand, the B group (FG) will take drugs orally three times a day within the trial 1 week. Meanwhile, with its combination element, the C group (FCF) is due to undertake both treatments and drugs as prescribed for A and B groups within the trial week. As an intra-trial arrangement, analgesic medication will be carefully administered for temporary pain release if the sudden intolerable pain appeared. For the primary outcome, this study is due to apply visual analogue scale to identify pain intensity relief. As the secondary outcomes are concerned, this study is aiming to focus on the issues related to changes in substance P and beta-endorphin concentrations in peripheral plasma, as well as those issues of analgesic needs, side effects, symptoms, and physical signs including pain classification, local itching, burning sensation, fever, local lymphadenopathy, skin lesion area, blisters, herpes clusters, vesicular traits, ulcers, and pimples; all these are taken into account for evaluation. For the final stage, the participants are to be followed up for postherpetic neuralgia.

Discussion

The results of this trial aim to provide sufficient evidence on FC treatment over both FG and FCF treatments. It will then give a credible alternative treatment to cut down acute pain and to cure AHZ infection.

Evaluation of Reporting Quality in Randomised Controlled Trials of Acupuncture for Acute Herpes Zoster by the CONSORT Statement and STRICTA Guidelines

Objective

To explore the methods for improving the reporting quality of randomised controlled trials (RCTs) on acupuncture through evaluating the reporting quality in RCTs of acupuncture for acute herpes zoster by the CONSORT statement and STRICTA guidelines.

Methods

English and Chinese databases were searched from database creation until October 2018 and updated to July 2019. The basic characteristics and methodological quality of the literatures included were evaluated based on the CONSORT statement and the STRICTA guidelines. Descriptive statistical analysis was used in this study. The agreement between the two researchers of all items was calculated by Cohen's kappa statistics.

Results

A total of 40 RCTs were included. Based on the CONSORT statement, items “Background,” “Randomised” in the title or abstract,” “Statistical methods,” and “Outcomes and estimation” were good reporting, with positive rates >80%. However, the quality of reporting in items “Sample size,” “Allocation concealment,” “Implementation,” “Blinding,” “Flow chart,” “Intent-to-treat analysis,” “Ancillary analyses,” and “Clinical Trials Register” was very poor, with positive rates <10%. Based on the STRICTA guidelines, good reporting existed in items “Acupuncture rational,” “Points used,” “Needle stimulation,” “Needle retention time,” “Course of treatment,” “Control intervention,” and “Treatment frequency,” with positive ratings >80%. The reporting quality of items “Numbers of needles inserted,” “Depth of insertion,” “Responses elicited,” and “Practitioner background” was lower, with positive rates <50%. The agreement of most items was judged as moderate, substantial, or good.

Conclusion

The reporting quality of RCTs in acupuncture for acute HZ is generally inadequate. It is necessary that researchers and journal editors learn and raise the adoption of the CONSORT statement and STRICTA guidelines to enhance the reporting quality of the RCTs in acupuncture.

Role of Complementary and Alternative Therapies in Infectious Disease

Complementary and alternative medicine (CAM) is increasingly being used in Western countries despite the lack of conclusive research studies. Several CAM modalities have only shown variable therapeutic efficacy in infectious disease management. Clinicians should be familiar with these therapies in order to advise patients about alternative therapeutic options when treating infections.
