Effectiveness of Acupuncture on Pain, Functional Disability, and Quality of Life in Rheumatoid Arthritis of the Hand: Results of a Double-Blind Randomized Clinical Trial.

BACKGROUND: Rheumatoid arthritis (RA) is characterized by pain, functional disability, poor quality of life (QoL), high socioeconomic impact, and annual costs of over $56 billion in the United States. Acupuncture (AC) is widely in use; however, studies show severe methodological shortcomings, did not consider the functional diagnosis for the allocation of acupoints and their results showed no differences between verum and control groups. OBJECTIVE: The authors aimed to objectively assess the safety and efficacy of AC treatments for RA. METHODS: 105 RA patients with a functional diagnosis of a "Pivot syndrome" or "Turning Point syndrome" were randomly assigned to (1) verum-AC (verum acupoints), (2) control-AC (sham acupoints-points outside of the conduits/meridians and of the extra-conduits), or (3) waiting list (each group n = 35). AC groups experienced the exact same number, depth, and stimulation of needles. Assessments took place before and 5 min after AC with follow-ups over 4 weeks. RESULTS: (1) Verum-AC significantly improved self-reported pain (Z = -5.099, p < 0.001) and pressure algometry (Z = -5.086, p < 0.001); hand grip strength (Z = -5.086, p < 0.001) and arm strength (Z = -5.086, p < 0.001); health status improved significantly (p < 0.001, Z = -4.895); QoL improved significantly in 7/8 survey domains; and number of swollen joints (Z = -2.862, p = 0.004) and tender joints (Z = -3.986, p < 0.001) significantly decreased. (2) Control-AC showed no significant changes, except in self-reported pain improvement. (3) Waiting list group showed an overall worsening. CONCLUSION: This is the first double-blind controlled study on AC in RA of the hand that objectively and specifically assesses positive effects supporting its integration in rheumatology. Acupoint allocation according to Chinese Medicine functional diagnoses is extremely relevant to assess AC effectiveness in a patient group primarily defined by a "western" medicine diagnosis. Based on clear allocation criteria for acupoints, the authors minimized the possible bias of unspecific and suggestive effects on the control group, showed the specific effects of the points chosen, improved efficacy, and identified an evidence base for AC.

Effectiveness of Acupuncture on Pain, Physical Function and Health-Related Quality of Life in Patients with Rheumatoid Arthritis: A Systematic Review of Quantitative Evidence.

OBJECTIVE: To identify and synthesize the most recent available evidence of effectiveness of acupuncture on pain, physical function and health-related quality of life (HRQoL) in patients with rheumatoid arthritis (RA). METHODS: A comprehensive search of 12 Western and Chinese databases was undertaken from their inception up to end of 2016. Randomized controlled trials (RCTs), concerning patients with RA treated with needle acupuncture, written in English, Portuguese, German or Chinese were included. Primary outcomes included pain, physical function and HRQoL. Secondary outcomes included morning stiffness, functional impairment, number of tender and swollen joints and serum concentrations of inflamatory markers. Methodological quality was assessed by three independent reviewers using the standardized critical appraisal instrument from the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument. RESULTS: Twenty-two studies met the inclusion criteria. Of those, 9 studies were excluded after assessment of their methodological quality. The remaining 13 original RCTs included 974 patients. Ten of these studies published in China, showed favorable statistical significant effects of acupuncture in relieving symptoms of RA compared with controls. CONCLUSIONS: Evidence suggests that acupuncture interventions may have a positive effect in pain relief, physical function and HRQoL in RA patients. However, due to the heterogeneity and methodologic limitations of the studies included in this systematic review, evidence is not strong enough to produce a best practice guideline.

Understanding Chinese Medicine Patterns of Rheumatoid Arthritis and Related Biomarkers.

Background: A considerable number of Rheumatoid Arthritis (RA) patients only experience side effects from treatment, with little to no actual pain relief. The combination of disease diagnosis in biomedicine and multi-disciplinary integrative approaches such as Chinese Medicine (CM), can help to identify different functional diagnosis of RA in the context of biomarker discovery. We aimed to analyse CM patterns in RA and their biomarker profiles. Methods: Four electronic databases (web of science, CINAHL, Scopus and PubMed) were searched. The reference list of all identified reports and articles were searched for additional studies. All study designs were included and no date limits were set. Studies were considered if they were published in English and explored the possible biomarkers profiles in RA patients, classified according to the American College of Rheumatology and categorized in CM as either cold, heat/hot or deficiency patterns. Methodological quality of included studies was assessed using checklists adapted from the ©Critical Appraisal Skills Programme by two independent reviewers. A narrative synthesis was conducted, using thematic analysis. Results: A total of 10 articles were included. The studies examined 77 healthy volunteers and 1150 RA patients categorized as cold, heat/hot or deficiency pattern and related biomarkers were identified individually or concomitantly. Conclusions: CM pattern differentiation based on clinical signs and symptoms showed a diverse range of biomolecules, proteins and genes from RA patients correlated well with cold, heat/hot or deficiency phenotype-based CM patterns and could be used as diagnostic biomarkers for early detection, disease monitoring and therapeutic targets.

The effectiveness of acupuncture on pain, physical function and health-related quality of life in patients with rheumatoid arthritis: a systematic review protocol.

REVIEW QUESTION/OBJECTIVE: The objective of this review is to identify and synthesize the best available evidence on the effectiveness of acupuncture on pain, physical function and health-related quality of life in patients with rheumatoid arthritis.More specifically, the review questions are:• Is acupuncture effective in improving health-related quality of life in patients with RA?• Is acupuncture effective in relieving pain in patients with RA?• Is acupuncture effective in improving physical function in patients with RA?

Evaluation of the effect of acupuncture on hand pain, functional deficits and health-related quality of life in patients with rheumatoid arthritis--A study protocol for a multicenter, double-blind, randomized clinical trial.

BACKGROUND: Rheumatoid arthritis (RA) is a systemic inflammatory disease characterized by functional disability and pain. Although acupuncture is widely used, until now Western acupuncture studies on RA have not shown conclusive positive results. Acupuncture is regarded as a reflex therapy that has effects on the human autonomic nervous system. By establishing a traditional Chinese medicine (TCM) diagnosis first, the practitioner is able to choose acupoints according to the state of each individual patient. METHODS/DESIGN: We are interested if acupuncture, using a classical diagnostic procedure to allocate acupoints to the patient according to the Shang Han Lun theory, can be effective in relieving pain, improving hand function and increasing health-related quality of life in RA.The authors intend to harmonize TCM diagnosis according to clinical and genetic profiles. Patients with the TCM diagnosis of a so-called Turning Point syndrome will be followed up in a randomized, prospective, double-blind, placebo-controlled, multicenter and three-armed parallel-group study with a standardized treatment in order to optimize potential therapeutic effects of acupuncture on pain, strength and muscle function of patients with RA as well as the influence on inflammation and quality of life. DISCUSSION: The findings of this study will provide important clinical information about the feasibility and efficacy of acupuncture treatment for RA patients. In addition, it will explore the feasibility of further acupuncture research. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Identifier NCT02553005.
