ABSTRACT
Objective:
To examine the effect of
acupressure on Raynaud’s phenomenon (RP) in a randomised controlled clinical
trial (RCT) and to evaluate the difficulties of conducting an RP RCT.
Methods:
A pilot single-center RCT of
acupressure versus targeted patient education was conducted for the treatment
of RP. Patients with either primary (n = 15) or secondary (n = 8) RP were
randomized in an 8-week study. The primary endpoints included a decrease in the
frequency and duration of RP. Secondary endpoints included several serum
biomarkers including endothelial dysfunction, Raynaud’s attack symptoms,
Raynaud’s Condition Score, and patient and physician global assessments of RP.
Primary data analysis was conducted using the last observation carried forward
and t-tests or a Wilcoxon rank test
was used to compare the two groups.
Results:
Twenty-three patients were randomized
and seven discontinued prematurely. Seventy-eight percent of patients were
female, 96% were Caucasian, and the mean age was 49.8 (SD = 16) years. No
statistically significant differences were detected between the acupressure
versus education groups in primary and secondary outcomes (p>0.05).
Frequency of attacks decreased by 6.7 attacks (SD = 8.8) in the acupressure
group versus 7.2 (SD = 12.8) in the education group (p = 0.96), and the
duration of attacks decreased by 11.4 (SD = 19.9) minutes in the acupressure
group versus an increase of 0.8 minutes (SD = 11.2) in the education group (p =
0.14). There were no adverse events noted in the RCT.
Conclusions:
This pilot study does not
support efficacy of acupressure for RP.
Introduction
RP is a condition caused by an
intermittent vasoconstriction of blood vessels in the extremities in response
to cold or emotional stress. In the USA, it affects 2% to 11% of women and 1.5%
to 8% of men. The burden of RP in the general population is quite high and can
lead to loss of productivity and a reduced quality of life.
Currently used pharmacologic
therapies for RP have only modest efficacy and can include calcium channel
blockers, angiotensin II antagonists, alpha-1 adrenergic blockers, selective
serotonin reuptake inhibitors, prostacyclins, nitrates, statins, botulin toxin,
phosphodiesterase inhibitors, endothelin receptor antagonists and antioxidants.
Side effects of these
therapies are common and efficacy is limited with the exception of calcium
channel blockers and prostacyclins, which decrease the frequency and duration
of attacks.
The high cost, lack of
efficacy, and side effects of traditional medical therapies make other
complementary treatments such as acupressure an attractive alternative.
Chinese acupuncture has been
reported in a randomized controlled study of 3 primary Raynaud’s syndrome
patients to decrease the frequency of RP attacks (n = 17) when compared to
placebo (n=16, p<0.01). However, acupuncture needs to be administered by
trained professionals, and usually requires an out of pocket expense.
Alternatively, acupressure uses pressure to stimulate key areas based upon
ancient Chinese medicine meridian theory.
The advantage of acupressure
is that it can be taught to patients and be self-administered at home. As such,
acupressure, may provide beneficial effects for the treatment of RP.
The purpose of this pilot
single-center trial was to evaluate the feasibility and potential efficacy of
standardized acupressure for improving circulation in RP. Among the outcome
measures, we included published patient-reported measures such as frequency of
RP, duration of RP attacks, patient assessment, attack symptoms (tingling,
numbness and pain), and the Raynaud’s Condition Score (RCS), physician global
assessment on a visual analogue score (VAS), serum biomarkers, and a measure of
endothelial function (EndoPAT). We also explored a recently reported composite
index in this trial.
Methods
Study design
Single center, unblinded,
randomised controlled trial that was conducted over a period of 8 weeks and was
approved by the University of Michigan Institutional Review Board. Two
acupressure protocols were examined: one focusing on vasodilation (thus
counteracting the vasospasm in RP), and the second focusing on relaxation.
The education (controlled)
group received an education packet provided by the Raynaud’s Association.
Patients
Patients with both primary and
secondary Raynaud’s were included and aged over 18.
Efficacy assessments
The primary outcomes were a
decrease in the frequency and duration of RP attacks during week eight compared
to the attacks during week one. Secondary assessments included RCS, RP pain,
tinging and numbness, which collectively were combined into the parameter
‘attack symptoms’, physician and patient global assessment on a VAS, and
EndoPAT. Serum markers included basic fibroblast growth factor (bFGF), vascular
cell adhesion molecule -1 (VCAM-1), soluble-intercellular cell adhesion
molecule-1 (slCAM-1), soluble-E-selectin (sE-selectin), tissue type plasminogen
activator (tPA), procollagen type I N-terminal propeptide (PINP), and vascular
endothelial growth factor (VEGF) were also assessed.
Adverse events
Patients did not experience
any adverse evens from acupressure with no bruising or pain reported. There was
a high drop-out rate approaching 30%, which is hypothesized to be due to the
difficulty in patients keeping up the daily acupressure treatment or due to
lack of efficacy.
Discussion
Identifying effective new
treatments for RP patients has been hampered by the variability in clinical
trial outcome measures used to assess efficacy. The variability and lack of
standardized outcome measures has also made it difficult to compare different
clinical trials as randomized controlled trials in RP often use different
clinical outcome measures, resulting in conflicting outcomes in different
trials. The variation in placebo response rates has made clinical trials
inconclusive rendering the approval of new therapies for RP difficult despite
anecdotal evidence of improvement.
The lack of reliable objective
biomarkers or endpoints to predict efficacy has also pushed investigators to
utlilize subjective endpoints that have high placebo response rates. Objective
measures have been shown to be reliable and valid but are not always available
for trials and there is a need for better outcome measures that can be
incorporated into multicenter trials.
The results showed decreased
endothelial function in the secondary RP group. It is unclear whether this lack
of significance is due to a lack of efficacy or due to a lack of sensitivity to
change in these tests that are used to detect the vascular changes attributed
to RP.
Key
Message
-
Acupressure is not effective for the treatment
of Raynaud’s phenomenon.
- Outcome measures in Raynaud’s phenomenon have a
high level of variability, making conclusive results difficult.
- A standardized composite index for RP or more
reliable outcome measures are needed for multicenter trials.

This year, I am celebrating 20 years of being a
patient at this world leading expert specialist research centre.
Sept 2017 |
I am eternally grateful to the global scleroderma
trail blazers Dame Prof Black and Prof Chris Denton, whose commitment and
dedication to unlocking the scleroderma enigma, is nothing other than,
superhuman.
I am truly humbled and inspired by their work
ethic. I am wholly appreciative for Prof Denton’s continued medical expertise
and support, especially during my barrister qualifying years, 1997 -
2004.
1st March 2004, I qualified as a self
employed practising barrister. Further to having been told in 1997, by my
diagnosing doctor, that I was looking at a 15month prognosis.
I very much hope to utilise my professional skills
and qualifications along with my patient experience, to help achieve the
#SclerodermaFreeWorld dream, hoping to improve understanding and best practice,
in the meantime.
