Here and elsewhere, I have repeatedly written about the many things that can go wrong with acupuncture. This invariably annoys acupuncture fans who usually counter by accusing me of being alarmist. Despite their opposition, I continue to think it is important to regularly point out that acupuncture – contrary to what many acupuncturists would tell us – can result in serious injury. I will therefore carry on reporting new evidence about the harm caused by acupuncture. Here is a very brief review of new (2014) articles on this important topic.

A recent study found that the incidence of any adverse events per patient was 42.4% with traditional acupuncture, 40.7% with minimal acupuncture and 16.7% with non-invasive sham acupuncture. These figures are much higher than those around 10% previously reported.

Other authors described the case of a broken off acupuncture needle in a patient’s abdomen. A very long needle was used which happily is unusual in routine practice.

Pneumothorax has been often noted as a complication of acupuncture – it is by far the most frequently reported serious complication caused by acupuncture; well over 100 instances have been described in the medical literature which, of course, reflects only the tip of an iceberg – new cases are being reported almost on a monthly basis.

Cardiac tamponade is even more dangerous but fortunately also much rarer. A case of life-threatening cardiac tamponade due to penetration of an acupuncture needle directly into the right ventricle was recently published. Cardiac tamponade can happen when the patient is unfortunate enough to have a sternal foramen, an congenital abnormality that is not normally detected by simple inspection or palpation. An investigation found that the frequency of a sternal foramen is approximately 10.5%. The authors concluded that sternal acupuncture should be planned in the region of corpus-previous CT should be done to rule out this variation. Furthermore, we strongly recommend the acupuncture technique which prescribes a safe superficial-oblique approach to the sternum.

A review from Egypt noted that acupuncture presented a significant risks for acquiring hepatitis C infections.

Other types of infections can also be transmitted by acupuncture needles, if the therapist fails to adhere to proper procedures of sterility. One report described the diagnosis, treatment and >1 year follow-up of 30 patients presenting with acupuncture-induced primary inoculation tuberculosis.

Similarly, Chinese authors reported the case of a 54-year-old woman who presented with progressive low back pain and fever. She underwent surgical decompression, with an immediate improvement of her pain. A culture of the epidural abscess grew Serratia marcescens. One year postoperatively, magnetic resonance imaging revealed the almost complete eradication of the abscess. This case is the first case of Serratia marcescens-associated spinal epidural abscess formation secondary to acupuncture.

Other authors reported a rare case of isolated unilateral hypoglossal nerve injury following ipsilateral acupuncture for migraines in a 53-year-old lady.

Finally, Greek authors published a case of severe rhabdomyolysis and acute kidney injury after acupuncture sessions. Rhabdomyolysis is a rare condition that can be caused by muscle injury and presents with muscle weakness and pain. It is characterized by myoglobinuria which, in turn, may cause acute kidney injury.

I can hear the world of acupuncture arguing that all of these events are extreme rarities and that conventional treatments are much more dangerous. This may well be true but it also ignores the following facts:

  • The frequency of such events is essentially unknown. Contrary to conventional medicine, alternative medicine has no functioning systems to monitor adverse events. Therefore the true incidence figures of acupuncture-related complications are anyone’s guess.
  • Most conventional treatments in common use are backed up by good evidence for efficacy and therefore demonstrably do more good than harm, even if they regularly cause adverse effects. This is not the case for acupuncture. In the absence of solid evidence for efficacy, even relatively rare or minor adverse effects would mean that the risk/benefit profile of acupuncture is not positive.

For these reasons, it is an ethical imperative, I think, to keep a keen eye on the harm caused by acupuncture and to inform the public about the fact that it is undeniably not free of risks.

An international team of researchers wanted to determine the efficacy of laser and needle acupuncture for chronic knee pain. They conducted a Zelen-design clinical trial (randomization occurred before informed consent), in Victoria, Australia (February 2010-December 2012). Community volunteers (282 patients aged ≥50 years with chronic knee pain) were treated by family physician acupuncturists.

The treatments consisted of A) no acupuncture (control group, n = 71), B) needle (n = 70), C) laser (n = 71), and D) sham laser (n = 70) acupuncture. Treatments were delivered for 12 weeks. Participants and acupuncturists were blinded to laser and sham laser acupuncture. Control participants were unaware of the trial.

Primary outcomes were average knee pain (numeric rating scale, 0 [no pain] to 10 [worst pain possible]; minimal clinically important difference [MCID], 1.8 units) and physical function (Western Ontario and McMaster Universities Osteoarthritis Index, 0 [no difficulty] to 68 [extreme difficulty]; MCID, 6 units) at 12 weeks. Secondary outcomes included other pain and function measures, quality of life, global change, and 1-year follow-up. Analyses were by intention-to-treat using multiple imputation for missing outcome data.

At 12 weeks and 1 year, 26 (9%) and 50 (18%) participants were lost to follow-up, respectively. Analyses showed neither needle nor laser acupuncture significantly improved pain (mean difference; -0.4 units; 95% CI, -1.2 to 0.4, and -0.1; 95% CI, -0.9 to 0.7, respectively) or function (-1.7; 95% CI, -6.1 to 2.6, and 0.5; 95% CI, -3.4 to 4.4, respectively) compared with sham at 12 weeks. Compared with control, needle and laser acupuncture resulted in modest improvements in pain (-1.1; 95% CI, -1.8 to -0.4, and -0.8; 95% CI, -1.5 to -0.1, respectively) at 12 weeks, but not at 1 year. Needle acupuncture resulted in modest improvement in function compared with control at 12 weeks (-3.9; 95% CI, -7.7 to -0.2) but was not significantly different from sham (-1.7; 95% CI, -6.1 to 2.6) and was not maintained at 1 year. There were no differences for most secondary outcomes and no serious adverse events.

The authors drew the following conclusions: In patients older than 50 years with moderate or severe chronic knee pain, neither laser nor needle acupuncture conferred benefit over sham for pain or function. Our findings do not support acupuncture for these patients.

This is one of the methodologically best acupuncture studies that I have seen so far.

  • its protocol has been published when the trial started thus allowing maximum transparency
  • it is adequately powered
  • it has a very clever study-design
  • it minimizes bias in all sorts of ways
  • it tests acupuncture for a condition that it is widely used for
  • it even manages to blind acupuncturists by using one treatment arm with laser acupuncture

The results show quite clearly that acupuncture does have mild effects on pain and function that entirely rely on a placebo response.

Will acupuncturists learn from this study and henceforward stop treating knee-patients? Somehow I doubt it! The much more likely scenario is that they will claim the trial was, for this or that reason, not valid. Acupuncture, like most of alternative medicine, seems unable to revise its dogma.

An article with this title was published recently by a team from Israel; essentially, it reports two interesting case histories:

Case 1

A 59-year-old male underwent a course of acupuncture for chronic low back pain, by a acupuncturist. During the therapy, the patient noted swelling at the point of puncture, but his therapist dismissed the claim. The region continued to swell, and three days later his family doctor diagnosed cellulitis and prescribed oral amoxicillin with clavulanic acid. The following day the patient’s condition worsened—he started to suffer from chills and more intense pain, so he went to the emergency room. At that stage, the patient had a fever of 37.9°C, a pulse of 119, and a blood pressure of 199/87. Edema was noted over the patient’s entire right flank (Figure 1A). Laboratory results were notable for a level of glucose of 298 mg/dL, sodium of 128 mmol/L, and white blood count (WBC) of 26,500 cells/μL with left shift. An emergency CT revealed an abscess of the abdominal wall involving the muscles, but no intra-abdominal pathology (Figure 1B).

Figure 1.
Figure 1.The patient received broad-spectrum antibiotics and was taken to the operating room for debridement. Upon incision there was subcutaneous edema with no puss, gangrene of the entire external oblique muscle, and an abscess between the external and internal oblique muscles. The muscles were debrided back to healthy, bleeding tissue and the wound copiously irrigated with saline. The wound was left open, with gauze and iodine as a cover. Gram stains and cultures returned group B streptococcus (GBS) sensitive to penicillin, and antibiotic coverage was adjusted accordingly. The patient returned to the operating room for serial debridement until the wound developed healthy granulation tissue. The patient received four units of blood and required 13 days of hospitalization. To date, he suffers from a disfiguring wound of his abdominal wall.

Considering the fact that group B streptococci live primarily in the female vagina, and that the acupuncturist was a young female, it is possible to assume that the cause for this grave illness was due to improper hygiene while treating our patient with acupuncture. Although rare, this tragic consequence of acupuncture has been seen previously by other researchers.

Case 2

A 27-year-old male with chronic cervical and back pain without any previous medical treatment or imaging was referred to a tertiary medical facility. To manage his pain, the patient used the services of a chiropractor who used cervical manipulation. Immediately after such a manipulation, the patient felt a severe cervical pain; 30 minutes after manipulation the patient started feeling paresthesia in his hands and legs. The patient was admitted to an emergency room with symptoms of progressive weakness in all four extremities and weakness. No additional symptoms were seen. Immediate MRI demonstrated an epidural hematoma at the C3-4 level (Figure 2).

Figure 2.
Figure 2.

The patient underwent immediate surgery to evacuate the hematoma via an anterior approach and C3-4 cage placement. The day after surgery the patient showed a remission of symptoms. At 6 months follow-up his remission was complete.

The literature includes several reports of SSPE immediately following a chiropractic manipulation that was considered the cause of this event. The authors of this case report concluded that chiropractic procedures can be dangerous when performed by practitioners who might be only partially trained, who might tend to perform an insufficient patient examination before the procedure, and thus endanger their patients.

On this blog, I have repeatedly warned that not all alternative treatments are free of risks. These two cases are impressive reminders of this undeniable fact.

I am sure that most proponents of alternative medicine will try to claim that

  • such complications are true rarities,
  • I am alarmist to keep alerting my readers to such events,
  • conventional medicine is dimensions more harmful,
  • the above cases are caused by poor practice.

However, I feel compelled to stress that there are no adequate post-marketing surveillance systems in alternative medicine and that the true frequencies of such events are therefore unknown. It seems therefore imperative (and not alarmist) to publicize such risks as widely as possible – in the hope that alternative practitioners, one day, might do the ethically and morally correct thing and implement proper surveillance of their practices.

For every condition which is not curable by conventional medicine there are dozens of alternative treatments that offer a cure or at least symptomatic relief. Multiple sclerosis (MS) is such a disease. It is hard to find an alternative therapy that is not being promoted for MS.

Acupuncture is, of course, no exception. It is widely promoted for treating MS symptoms and many MS patients spend lots of money hoping that it does. The US ‘National MS Society’, For instance claim that acupuncture may provide relief for some MS-related symptoms, including pain, spasticity, numbness and tingling, bladder problems, and depression. There is no evidence, however, that acupuncture can reduce the frequency of MS exacerbations or slow the progression of disability. And the ‘British Acupuncture Council’ state that acupuncture may provide relief for some MS-related symptoms, including pain, spasticity, numbness and tingling, bladder problems, and depression.

Such claims seem a little over-optimistic; let’s have a look what the evidence really tells us.

The purpose of this brand-new review was to assess the literature on the effectiveness of acupuncture for treating MS. A literature search resulted in 12 peer-reviewed articles on the subject that examined the use of acupuncture to treat MS related quality of life, fatigue, spasticity, and pain. The majority of the studies were poorly designed-without control, randomization, or blinding. Description of the subjects, interventions, and outcome measures as well as statistical analysis were often lacking or minimal.

The authors concluded that although many of the studies suggested that acupuncture was successful in improving MS related symptoms, lack of statistical rigor and poor study design make it difficult to draw any conclusions about the true effectiveness of this intervention in the MS population. Further studies with more rigorous designs and analysis are needed before accurate claims can be made as to the effectiveness of acupuncture in this population.

And what about other alternative therapies? Our own systematic review of the subject included 12 randomized controlled trials: nutritional therapy (4), massage (1), Feldenkrais bodywork (1), reflexology (1), magnetic field therapy (2), neural therapy (1) and psychological counselling (2). But the evidence was not compelling for any of these therapies, with many trials suffering from significant methodological flaws. There is evidence to suggest some benefit of nutritional therapy for the physical symptoms of MS. Magnetic field therapy and neural therapy appear to have a short-term beneficial effect on the physical symptoms of MS. Massage/bodywork and psychological counselling seem to improve depression, anxiety and self-esteem.

That was some time ago,  and it is therefore reasonable to ask: has the evidence changed? Thankfully, the ‘American Academy of Neurology’ has just published the following guidelines entitles complementary and alternative medicine in multiple sclerosis:

Clinicians might offer oral cannabis extract for spasticity symptoms and pain (excluding central neuropathic pain) (Level A). Clinicians might offer tetrahydrocannabinol for spasticity symptoms and pain (excluding central neuropathic pain) (Level B). Clinicians should counsel patients that these agents are probably ineffective for objective spasticity (short-term)/tremor (Level B) and possibly effective for spasticity and pain (long-term) (Level C). Clinicians might offer Sativex oromucosal cannabinoid spray (nabiximols) for spasticity symptoms, pain, and urinary frequency (Level B). Clinicians should counsel patients that these agents are probably ineffective for objective spasticity/urinary incontinence (Level B). Clinicians might choose not to offer these agents for tremor (Level C). Clinicians might counsel patients that magnetic therapy is probably effective for fatigue and probably ineffective for depression (Level B); fish oil is probably ineffective for relapses, disability, fatigue, MRI lesions, and quality of life (QOL) (Level B); ginkgo biloba is ineffective for cognition (Level A) and possibly effective for fatigue (Level C); reflexology is possibly effective for paresthesia (Level C); Cari Loder regimen is possibly ineffective for disability, symptoms, depression, and fatigue (Level C); and bee sting therapy is possibly ineffective for relapses, disability, fatigue, lesion burden/volume, and health-related QOL (Level C). Cannabinoids may cause adverse effects. Clinicians should exercise caution regarding standardized vs nonstandardized cannabis extracts and overall CAM quality control/nonregulation. Safety/efficacy of other CAM/CAM interaction with MS disease-modifying therapies is unknown.

Interestingly, on yesterday it was announced that the NHS in Wales has just made available a cannabis-based spray for MS-sufferers (I should mention that most cannabis-based preparations are not full plant extracts and thus by definition not herbal but conventional medicines).

It would be wonderful, if other alternative therapies were of proven benefit to MS-sufferers. But sadly, this does not seem to be the case. I think it is better to be truthful about this than to raise false hopes of desperate patients.

There must be well over 10 000 clinical trials of acupuncture; Medline lists ~5 000, and many more are hidden in the non-Medline listed literature. That should be good news! Sadly, it isn’t.

It should mean that we now have a pretty good idea for what conditions acupuncture is effective and for which illnesses it does not work. But we don’t! Sceptics say it works for nothing, while acupuncturists claim it is a panacea. The main reason for this continued controversy is that the quality of the vast majority of these 10 000 studies is not just poor, it is lousy.

“Where is the evidence for this outraging statement???” – I hear the acupuncture-enthusiasts shout. Well, how about my own experience as editor-in-chief of FACT? No? Far too anecdotal?

How about looking at Cochrane reviews then; they are considered to be the most independent and reliable evidence in existence? There are many such reviews (most, if not all [co-]authored by acupuncturists) and they all agree that the scientific rigor of the primary studies is fairly awful. Here are the crucial bits of just the last three; feel free to look for more:

All of the studies had a high risk of bias

All included trials had a high risk of bias…

The studies were not judged to be free from bias…

Or how about providing an example? Good idea! Here is a new trial which could stand for numerous others:

This study was performed to compare the efficacy of acupuncture versus corticosteroid injection for the treatment of Quervain’s tendosynovitis (no, you do not need to look up what condition this is for understanding this post). Thirty patients were treated in two groups. The acupuncture group received 5 acupuncture sessions of 30 minutes duration. The injection group received one methylprednisolone acetate injection in the first dorsal compartment of the wrist. The degree of disability and pain was evaluated by using the Quick Disabilities of the Arm, Shoulder, and Hand (Q-DASH) scale and the Visual Analogue Scale (VAS) at baseline and at 2 weeks and 6 weeks after the start of treatment. The baseline means of the Q-DASH and the VAS scores were 62.8 and 6.9, respectively. At the last follow-up, the mean Q-DASH scores were 9.8 versus 6.2 in the acupuncture and injection groups, respectively, and the mean VAS scores were 2 versus 1.2. Thus there were short-term improvements of pain and function in both groups.

The authors drew the following conclusions: Although the success rate was somewhat higher with corticosteroid injection, acupuncture can be considered as an alternative option for treatment of De Quervain’s tenosynovitis.

The flaws of this study are exemplary and numerous:

  • This should have been a study that compares two treatments – the technical term is ‘equivalence trial – and such studies need to be much larger to produce a meaningful result. Small sample sizes in equivalent trials will always make the two treatments look similarly effective, even if one is a pure placebo.
  • There is no gold standard treatment for this condition. This means that a comparative trial makes no sense at all. In such a situation, one ought to conduct a placebo-controlled trial.
  • There was no blinding of patients; therefore their expectation might have distorted the results.
  • The acupuncture group received more treatments than the injection group; therefore the additional attention might have distorted the findings.
  • Even if the results were entirely correct, one cannot conclude from them that acupuncture was effective; the notion that it was similarly ineffective as the injections is just as warranted.

These are just some of the most fatal flaws of this study. The sad thing is that similar criticisms can be made for most of the 10 000 trials of acupuncture. But the point here is not to nit-pick nor to quack-bust. My point is a different and more serious one: fatally flawed research is not just a ‘poor show’, it is unethical because it is a waste of scarce resources and, even more importantly, an abuse of patients for meaningless pseudo-science. All it does is it misleads the public into believing that acupuncture might be good for this or that condition and consequently make wrong therapeutic decisions.

In acupuncture (and indeed in most alternative medicine) research, the problem is so extremely wide-spread that it is high time to do something about it. Journal editors, peer-reviewers, ethics committees, universities, funding agencies and all others concerned with such research have to work together so that such flagrant abuse is stopped once and for all.

If you are pregnant, a ‘breech presentation’ is not good news. It occurs when the fetus presents ‘bottom-down’ in the uterus. There are three types:

  • Breech with extended legs (frank) – 85% of cases
  • Breech with fully flexed legs (complete)
  • Footling (incomplete) with one or both thighs extended

The significance of breech presentation is its association with higher perinatal mortality and morbidity when compared to cephalic presentations. This is due both to pre-existing congenital malformation, increased incidence of breech in premature deliveries and increased risk of intrapartum trauma or asphyxia. Caesarean section has been adopted as the ‘normal’ mode of delivery for term breech presentations in Europe and the USA, as the consensus is that this reduces the risk of birth-related complications.

But Caesarian section is also not a desirable procedure. Something far less invasive would be much more preferable, of course. This is where the TCM-practitioners come in. They claim they have the solution: moxibustion, i.e. the stimulation of acupuncture points by heat. But does it really work? Can it turn the fetus into the correct position?

This new study aimed to assess the efficacy of moxibustion (heating of the acupuncture needle with an igniting charcoal moxa stick) with acupuncture for version of breech presentations to reduce their rate at 37 weeks of gestation and at delivery. It was a randomized, placebo-controlled, single-blind trial including 328 pregnant women recruited in a university hospital center between 33 4/7 and 35 4/7 weeks of gestation. Moxibustion with acupuncture or inactivated laser (placebo) treatment was applied to point BL 67 for 6 sessions. The principal endpoint was the percentage of fetuses in breech presentation at 37 2/7 weeks of gestation.

The results show that the percentage of fetuses in breech presentation at 37 2/7 weeks of gestation was not significantly different in both groups (72.0 in the moxibustion with acupuncture group compared with 63.4% in the placebo group).

The authors concluded that treatment by moxibustion with acupuncture was not effective in correcting breech presentation in the third trimester of pregnancy.

You might well ask why on earth anyone expected that stimulating an acupuncture point would turn a fetus in the mother’s uterus into the optimal position that carries the least risk during the process of giving birth. This is what proponents of this technique say about this approach:

During a TCM consultation to turn a breech baby the practitioner will take a comprehensive case history, make a diagnosis and apply the appropriate acupuncture treatment.  They will assess if moxibustion might be helpful. Practitioners will then instruct women on how to locate the appropriate acupuncture points and demonstrate how to safely apply moxa at home. The acupuncture point UB 67 is the primary point selected for use because it is the most dynamic point to activate the uterus.  Its forte is in turning malpositioned babies.  It is located on the outer, lower edge of both little toenails. According to TCM theory, moxa has a tonifying and warming effect which promotes movement and activity.  The nature of heat is also rising.  This warming and raising effect is utilised to encourage the baby to become more active and lift its bottom up in order to gain adequate momentum to summersault into the head down position. This technique can also be used to reposition transverse presentation, a situation where the baby’s has its shoulder or back pointing down, or is lying sideways across the abdomen.

Not convinced? I can’t say I blame you!

Clearly, we need to know what the totality of the most reliable evidence shows; and what better than a Cochrane review to inform us about it? Here is what it tells us:

Moxibustion was not found to reduce the number of non-cephalic presentations at birth compared with no treatment (P = 0.45). Moxibustion resulted in decreased use of oxytocin before or during labour for women who had vaginal deliveries compared with no treatment (risk ratio (RR) 0.28, 95% confidence interval (CI) 0.13 to 0.60). Moxibustion was found to result in fewer non-cephalic presentations at birth compared with acupuncture (RR 0.25, 95% CI 0.09 to 0.72). When combined with acupuncture, moxibustion resulted in fewer non-cephalic presentations at birth (RR 0.73, 95% CI 0.57 to 0.94), and fewer births by caesarean section (RR 0.79, 95% CI 0.64 to 0.98) compared with no treatment. When combined with a postural technique, moxibustion was found to result in fewer non-cephalic presentations at birth compared with the postural technique alone (RR 0.26, 95% CI 0.12 to 0.56).

In other words, there is indeed some encouraging albeit not convincing evidence! How can this be? There is no plausible explanation why this treatment should work!

But there is a highly plausible explanation why the results of many of the relevant trials are false-positive thus rendering a meta-analysis false-positive as well. I have repeatedly pointed out on this blog that practically all Chinese TCM-studies report (false) positive results; and many of the studies included in this review were done in China. The Cochrane review provides a strong hint about the lack of rigor in its ‘plain language summary':

The included trials were of moderate methodological quality, sample sizes in some of the studies were small, how the treatment was applied differed and reporting was limited. While the results were combined they should be interpreted with caution due to the differences in the included studies. More evidence is needed concerning the benefits and safety of moxibustion.

So, would I recommend moxibustion for breech conversion? I don’t think so!

Auricular acupuncture (AA), according to the ‘COLLEGE OF AURICULAR ACUPUNCTURE’, has its origins in Modern Europe. In 1957 Dr. Paul Nogier, a neurologist from Lyons in France, observed a locum doctor treating sciatica by cauterizing an area of the ear. This prompted extensive research culminating in the development of the somatopic correspondence of specific parts of the body to the ear based upon the concept of an inverted foetus. Dr. Nogier believed that pain and other symptoms in the body could be alleviated by needling, massaging or electronically stimulating the corresponding region of the ear. Auricular Acupuncture is a specialized complementary therapy where acupuncture points on the outer ear are treated, using either needles or acupunctoscopes (electrical location and stimulation machines) to help relieve many chronic complaints. There are over 200 acupuncture points on the ear, each point named after an area of our anatomy. The outer ear acts like a switchboard to the brain. Each acupuncture point being treated, triggers electrical impulses from the ear via the brain, to the specific part of the body being treated.

Sounds odd? Well, that’s because it is odd!

But just because something is odd does not mean it is ineffective – so, what does the reliable evidence tell us? Here are some conclusions from systematic reviews:

The evidence that auricular acupuncture reduces postoperative pain is promising but not compelling.

The evidence for the effectiveness of AA for the symptomatic treatment of insomnia is limited.

The benefit of ear-acupressure for symptomatic relief of allergic rhinitis is unknown…

All of these analyses point out that the quality of the studies is usually very poor, and stress that more and better research is required. It is therefore interesting to note that a new study has just been published. Perhaps it could settle the question about the effectiveness of AA?

The aim of this study was 1) to evaluate whether auricular acupuncture effective for reducing health care provider stress and anxiety and 2) to determine, if auricular acupuncture impacts provider capacity for developing caring relationships with patients. Pre-intervention and post-intervention surveys were evaluated to see, if auricular acupuncture was associated with changes in State-Trait Anxiety Inventory (STAI), Professional Quality of Life, and Caring Ability Inventory scores. The results indicate that, compared with baseline, participants had a significant reduction in state anxiety (STAI), trait anxiety (STAI), burnout, and secondary traumatic stress scores (Professional Quality of Life). Significant increases were noted in courage and patience, two dimensions of the Caring Ability Inventory.

From these findings, the authors conclude that auricular acupuncture is an effective intervention for the relief of stress/anxiety in providers and supports heightened capacity for caring.

Sounds odd again? Yes, because it is odd!

I would argue that a study of any controversial therapy that has already been tested repeatedly in poor quality trials must have sufficient scientific rigor to advance the field of inquiry. If it does not fulfil this criterion, it is quite simply not ethical. The new study does not even have a control group; we can therefore not begin to tell whether the observed outcomes were due to non-specific effects, the natural history of the condition or regression towards the mean (to mention but a few of the possible sources of bias). To conclude that AA is ‘an effective intervention’ is therefore utterly barmy.

All of this could be entirely trivial and inconsequential. I am afraid, however, that it is not. Alternative medicine is littered with such unethically flawed research conducted by naïve and clueless pseudo-scientists who arrive at outrageous conclusions. This relentless flow of false-positive findings misleads consumers, health care professionals, decision makers and everyone else to draw the wrong conclusions about bogus therapies. And, in the end, this sort of thing even does a grave disfavour to any branch of alternative medicine that might have some degree of respectability.

IT IS HIGH TIME THAT THIS NONSENSE STOPS! IT BORDERS ON SCIENTIFIC MISCONDUCT.

A new book is currently being promoted. It specifically targets cancer patients and misleads them into thinking that alternative therapies offer hope for this vulnerable group of patients. Here is what the press release says:

Endeavoring to provide the 1.2 million Americans diagnosed with cancer annually with alternative treatments co-authors Johanna C. Schipper and Frank J. Vanderlugt announce the launch of “The Natural Cancer Handbook”. The useful book explores how more than fifty alternative treatments work, their price, and where they can be obtained…. Contributing to the war on cancer with a bevy of scientific and anecdotal evidence to support the effectiveness of the treatments the handbook is a respite from the mixed messages patients often endure.

With more than fifty of the most effective alternative cancer treatments listed The Natural Cancer Handbook is the work of two years of research. Used successfully over the last century, the remedies found in the handbook are significantly cheaper than standard cancer treatments and in most cases can be used alongside them.

…The handbook discusses the successful alternative treatments Budwig Diet, Beta 1, 3D Glucan, and the readily available green food supplements such as barley grass, chlorella and spirulina. The Natural Cancer Handbook also explores the benefits of Melatonin, Noni, Resveratrol and the Canadian Resonant Light and the Hulda Clark generators.

Vanderlugt is a Chartered Accountant with a Bachelor of Science in Biology and Schipper has researched cancer extensively and has five years training in medicine.

Let’s just take the first treatment mentioned above; this is what a reliable source like CANCER RESEARCH UK have to say about it:

The Budwig diet was developed by a German biochemist called Johanna Budwig in the 1950s. It involves eating flaxseed mixed with cottage cheese or milk. Flax is a plant grown in many parts of the world. Pressing its seeds produces linseed oil to use in cooking or as a food supplement. The seeds contain high levels of fibre and many vitamins and minerals. You grind the flaxseed, usually in a coffee grinder. As well as flaxseed and cottage cheese, the Budwig diet is rich in fruit, vegetables and fibre. You also have to avoid sugar, meat, and fats such as butter, margarine and salad oil.

There is no reliable scientific evidence to show that the Budwig diet (or any highly specific diet) helps people with cancer. It is important to make sure that you have a well balanced diet when you are ill, especially if you are undernourished. We know from research that a healthy, well balanced diet can reduce the risk of cancer. You can find information about diet, healthy eating and cancer on our News and Resources website.

This is a polite way of telling us that diets such as this one is not balanced and not what cancer patients need; in fact, such diets are not just ineffective, they can be dangerous to cancer patients.

Texts like the Natural Cancer Handbook tend to make me quite angry. I find it deeply immoral to mislead cancer patients in this way, simply to make a profit. The truth could not be simpler: There is and never will be such a thing as an alternative cancer ‘cure’.

The concept assumes that there exists an effective cure which is being suppressed only because it originates from alternative medicine circles. But this assumption is idiotic. As soon as a treatment shows promise, it will be picked up by the scientific and oncologic communities and researched until its therapeutic value is known. At the end of this process, we might have a new option to treat cancer effectively. Many examples exist where a new drug was developed from a plant; taxol is but one of many examples.

Those who deny these simple facts in order to make a fast buck from the desperation of some of the most vulnerable patients are, in my view, charlatans of the worst kind.

Imagine an area of therapeutics where 100% of all findings of hypothesis-testing research is positive, i.e. comes to the conclusion that the treatment in question is effective. Theoretically, this could mean that the therapy is a miracle cure which is useful for every single condition in every single setting. But sadly, there are no miracle cures. Therefore something must be badly and worryingly amiss with the research in an area that generates 100% positive results.

Acupuncture is such an area; we and others have shown that Chinese trials of acupuncture hardly ever produce a negative finding. In other words, one does not need to read the paper, one already knows that it is positive – even more extreme: one does not need to conduct the study, one already knows the result before the research has started. But you might not believe my research nor that of others. We might be chauvinist bastards who want to discredit Chinese science. In this case, you might perhaps believe Chinese researchers.

In this systematic review, all randomized controlled trials (RCTs) of acupuncture published in Chinese journals were identified by a team of Chinese scientists. A total of 840 RCTs were found, including 727 RCTs comparing acupuncture with conventional treatment, 51 RCTs with no treatment controls, and 62 RCTs with sham-acupuncture controls. Among theses 840 RCTs, 838 studies (99.8%) reported positive results from primary outcomes and two trials (0.2%) reported negative results. The percentages of RCTs concealment of the information on withdraws or sample size calculations were 43.7%, 5.9%, 4.9%, 9.9%, and 1.7% respectively.

The authors concluded that publication bias might be major issue in RCTs on acupuncture published in Chinese journals reported, which is related to high risk of bias. We suggest that all trials should be prospectively registered in international trial registry in future.

I applaud the authors’ courageous efforts to conduct this analysis, but I do not agree with their conclusion. The question why all Chinese acupuncture trials are positive has puzzled me since many years, and I have quizzed numerous Chinese colleagues why this might be so. The answer I received was uniformly that it would be very offensive for Chinese researchers to conceive a study that does not confirm the views held by their peers. In other words, acupuncture research in China is conducted to confirm the prior assumption that this treatment is effective. It seems obvious that this is an abuse of science which must cause confusion.

Whatever the reasons for the phenomenon, and we can only speculate about them, the fact has been independently confirmed several times and is now quite undeniable: acupuncture trials from China – and these constitute the majority of the evidence-base in this area – cannot be trusted. The only way to adequately deal with this problem that I can think of is to discard them outright.

An article in the ‘Huffpost Healthy Living’ recently discussed “the top three things that surprise people about acupuncture”. On closer inspection, they turn out to be the top three untruths about acupuncture. Here is (in italics and slightly abbreviated) what the article said.

Acupuncture is not just for pain

…It’s true that acupuncture can work wonders on pain conditions…However, acupuncture can alleviate a wide variety of ailments that have nothing to do with physical pain. Whether you have digestive issues, gynecological conditions, emotional concerns such as anxiety and depression, asthma, seasonal allergies, you name it, acupuncture can help address your symptoms.

Acupuncturists go to school for a long time

People tend to be unaware of the extent to which acupuncturists train to become licensed in their profession. Many assume becoming an acupuncturist is similar to becoming a massage therapist or Reiki practitioner or yoga instructor… At minimum, a licensed acupuncturist in the United States has been to three years of graduate school. Four years is more common. They hold master’s degrees. Some acupuncturists with doctorates have studied at the graduate level for five-plus years. Upon graduating from an accredited school, all acupuncturists must pass multiple board exams to become licensed in their state. In addition to the academic and state requirements for practicing acupuncture, many acupuncturists seek hands-on training and mentorship in the form of apprenticeships and continuing education seminars.

Acupuncture is relaxing

Acupuncture needles are surprisingly thin. They do not bear any resemblance to needles that are used for injections or to draw blood… In most cases, the insertion of acupuncture needles does not hurt…Once the needles are in, they start working their magic, which is where the relaxation part comes in. Acupuncture helps shift your body out of sympathetic mode (fight or flight) and into parasympathetic mode (rest and digest). It mellows out the nervous system, decreases muscular tension, and helps quiet internal chatter…

AND NOW THE FACTS:

1) There is not a single condition for which the evidence is truly compelling demonstrating that acupuncture is more than a placebo. Certainly there is no good evidence that acupuncture works for digestive issues, gynecological conditions, emotional concerns such as anxiety and depression, asthma or seasonal allergies.

2) In most countries, anyone can call themselves an acupuncturist, regardless of background or training.

3) The relaxing element of an acupuncture session is foremost the fact that patients lie down and have to keep still for 20 minutes or so. The insertion of needles does cause mild pain in many patients, and the claim about parasympathetic mode is mostly phantasy.

I despair about the nonsense that is published about alternative medicine on a daily basis – not because I have an axe to grind, but because it misleads patients into making wrong therapeutic decisions.
