bogus claims

A most excellent comment by Donald Marcus on what many now call ‘quackademia‘ (the disgraceful practice of teaching quackery (alternology) such as homoeopathy, acupuncture or chiropractic at universities as if they were legitimate medical professions) has recently been published in the BMJ.

Please allow me to quote extensively from it:

A detailed review of curriculums created by 15 institutions that received educational grants from the National Center for Complementary and Alternative Medicine (NCCAM) showed that they failed to conform to the principles of evidence based medicine. In brief, they cited many poor quality clinical trials that supported the efficacy of alternative therapies and omitted negative clinical trials; they had not been updated for 6-7 years; and they omitted reports of serious adverse events associated with CAM therapies, especially with chiropractic manipulation and with non-vitamin, non-mineral dietary supplements such as herbal remedies. Representation of the curriculums as “evidence based” was inaccurate and unjustified. Similar defects were present in the curriculums of other integrative medicine programs that did not receive educational grants….

A re-examination of the integrative medicine curriculums reviewed previously showed that they were essentially unchanged since their creation in 2002-03…Why do academic centers that are committed to evidence based medicine and to comparative effectiveness analysis of treatments endorse CAM? One factor may be a concern about jeopardizing income from grants from NCCAM, from CAM clinical practice, and from private foundations that donate large amounts of money to integrative medicine centers. Additional factors may be concern about antagonizing faculty colleagues who advocate and practice CAM, and inadequate oversight of curriculums.

By contrast to the inattention of US academics and professional societies to CAM education, biomedical scientists in Great Britain and Australia have taken action. At the beginning of 2007, 16 British universities offered 45 bachelor of science degrees in alternative practices. As the result of a campaign to expose the lack of evidence supporting those practices, most courses in alternative therapies offered by public universities in Britain have been discontinued. Scientists, physicians, and consumer advocates in Australia have formed an organization, Friends of Science in Medicine, to counter the growth of pseudoscience in medicine.

The CAM curriculums violate every tenet of evidence based medicine, and they are a disservice to learners and to the public. It could be argued that, in the name of academic freedom, faculty who believe in the benefits of CAM have a right to present their views. However, as educators and role models they should adhere to the principles of medical professionalism, including “a duty to uphold scientific standards.” Faculty at health profession schools should urge administrators to appoint independent committees to review integrative medicine curriculums, and to consider whether provision of CAM clinical services is consistent with a commitment to scholarship and to evidence based healthcare.

One of the first who openly opposed science degrees without science was David Colquhoun; in an influential article published in Nature, he wrote:

The least that one can expect of a bachelor of science (BSc) honours degree is that the subject of the degree is science. Yet in December 2006 the UK Universities and Colleges Admissions Service advertised 61 courses for complementary medicine, of which 45 are BSc honours degrees. Most complementary and alternative medicine (CAM) is not science because the vast majority of it is not based on empirical evidence. Homeopathy, for example, has barely changed since the beginning of the nineteenth century. It is much more like religion than science. Worse still, many of the doctrines of CAM, and quite a lot of its practitioners, are openly anti-science.

More recently, Louise Lubetkin wrote in her post ‘Quackademia‘ that alternative medicine and mainstream medicine are absolutely not equivalent, nor are they by any means interchangeable, and to speak about them the way one might when debating whether to take the bus or the subway to work – both will get you there reliably – constitutes an assault on truth.

I think ‘quackademia’ is most definitely an assault on truth – and I certainly know what I am talking about. When, in 1993, I was appointed as Professor of Complementary Medicine at Exeter, I became the director of a pre-existing team of apologists teaching a BSc-course in alternative medicine to evangelic believers. I was horrified and had to use skill, diplomacy and even money to divorce myself from this unit, an experience which I will not forget in a hurry. In fact, I am currently writing it up for a book I hope to publish soon which covers not only this story but many similarly bizarre encounters I had while researching alternative medicine during the last two decades.

Acupressure is a treatment-variation of acupuncture; instead of sticking needles into the skin, pressure is applied over ‘acupuncture points’ which is supposed to provide a stimulus similar to needling. Therefore the effects of both treatments should theoretically be similar.

Acupressure could have several advantages over acupuncture:

  • it can be used for self-treatment
  • it is suitable for people with needle-phobia
  • it is painless
  • it is not invasive
  • it has less risks
  • it could be cheaper

But is acupressure really effective? What do the trial data tell us? Our own systematic review concluded that the effectiveness of acupressure is currently not well documented for any condition. But now there is a new study which might change this negative verdict.

The primary objective of this 3-armed RCT was to assess the effectiveness and cost-effectiveness of self-acupressure using wristbands compared with sham acupressure wristbands and standard care alone in the management of chemotherapy-induced nausea. 500 patients from outpatient chemotherapy clinics in three regions in the UK involving 14 different cancer units/centres were randomised to the wristband arm, the sham wristband arm and the standard care only arm. Participants were chemotherapy-naive cancer patients receiving chemotherapy of low, moderate and high emetogenic risk. The experimental group were given acupressure wristbands pressing the P6 point (anterior surface of the forearm). The Rhodes Index for Nausea/Vomiting, the Multinational Association of Supportive Care in Cancer (MASCC) Antiemesis Tool and the Functional Assessment of Cancer Therapy General (FACT-G) served as outcome measures. At baseline, participants completed measures of anxiety/depression, nausea/vomiting expectation and expectations from using the wristbands.

Data were available for 361 participants for the primary outcome. The primary outcome analysis (nausea in cycle 1) revealed no statistically significant differences between the three arms. The median nausea experience in patients using wristbands (both real and sham ones) was somewhat lower than that in the anti-emetics only group (median nausea experience scores for the four cycles: standard care arm 1.43, 1.71, 1.14, 1.14; sham acupressure arm 0.57, 0.71, 0.71, 0.43; acupressure arm 1.00, 0.93, 0.43, 0). Women responded more favourably to the use of sham acupressure wristbands than men (odds ratio 0.35 for men and 2.02 for women in the sham acupressure group; 1.27 for men and 1.17 for women in the acupressure group). No significant differences were detected in relation to vomiting outcomes, anxiety and quality of life. Some transient adverse effects were reported, including tightness in the area of the wristbands, feeling uncomfortable when wearing them and minor swelling in the wristband area (n = 6). There were no statistically significant differences in the costs associated with the use of real acupressure band.

26 subjects took part in qualitative interviews. Participants perceived the wristbands (both real and sham) as effective and helpful in managing their nausea during chemotherapy.

The authors concluded that there were no statistically significant differences between the three arms in terms of nausea, vomiting and quality of life, although apparent resource use was less in both the real acupressure arm and the sham acupressure arm compared with standard care only; therefore; no clear conclusions can be drawn about the use of acupressure wristbands in the management of chemotherapy-related nausea and vomiting. However, the study provided encouraging evidence in relation to an improved nausea experience and some indications of possible cost savings to warrant further consideration of acupressure both in practice and in further clinical trials.

I could argue about several of the methodological details of this study. But I resist the temptation in order to focus on just one single point which I find important and which has implications beyond the realm of acupressure.

Why on earth do the authors conclude that no clear conclusions can be drawn about the use of acupressure wristbands in the management of chemotherapy-related nausea and vomiting? The stated aim of this RCT was to assess the effectiveness and cost-effectiveness of self-acupressure using wristbands compared with sham acupressure wristbands and standard care. The results failed to show significant differences of the primary outcome measures, consequently the conclusion cannot be “unclear”, it has to be that ACUPRESSURE WRIST BANDS ARE NOT MORE EFFECTIVE THAN SHAM ACUPRESSURE WRIST BANDS AS AN ADJUNCT TO ANTI-EMETIC DRUG TREATMENT (or something to that extent).

As long as RCTs of alternative therapies are run by evangelic believers in the respective therapy, we are bound to regularly encounter this lamentable phenomenon of white-washing negative findings with an inadequate conclusion. In my view, this is not research or science, it is pseudo-research or pseudo-science. And it is much more than a nuisance or a trivial matter; it is a waste of research funds, a waste of patients’ good will that has reached a point where people will lose trust in alternative medicine research. Someone should really do a systematic study to identify those research teams that regularly commit such scientific misconduct and ensure that they are cut off public funding and support.

I am delighted to report that my invitation to contribute AT FAPs was successful! Some readers did indeed cotton on and submitted their funny satire and bizarre absurdities – oddly enough, they are all homeopathic by nature. If you like to know more about the idea of AT FAPs, please see here. And do not forget: if you want me to continue with this feature, keep your alt med satire coming!

AT FAP No 4 (sent in by an anonymous reader)

You’ve heard or Gerson but now we can reveal Dyson therapy!

The well established and long-proven facts of homeopathy – that like cures like, ultra diluted solutions of nothing are incredibly potent medicines, Hahnemann can’t be wrong etc. have, of course revolutionised our world view.  Nothing substantial had changed in homeopathy for 200 years, until now!  Vacuous homeopaths have now discovered an amazing breakthrough- Dyson therapy. After extensive research one afternoon, they have made a breakthrough that will rock the world and clean your carpet.

Some homeopaths believe that ultra diluted water contains silica that is remarkably similar to that found in the glass vessels it is prepared in. Vacuous homeopaths have found a way to reduce the content of the water still further, indeed eliminate it completely!

Using the principle of like cures like, a material is chosen for its powerful homeopathic effects,  and ground up in a small amount of water and/or alcohol until it turns into a paste or solution. Now here’s the science bit- it is then smeared on the floor. After being allowed to dry for precisely 3.4 minutes (trust us) it is then vacuumed up! This amazing breakthrough allows the nano-bollock essence of the material to be firmly trapped within the vacuum cleaner, but here is the genius part-as air is drawn over it the nano-bollock material is infinitely diluted. No need for complicated machines you can do this yourself at home. Vacuous homeopaths have found that the vacuum cleaner has to be tapped on the floor during the process, or for a far more potent effect on the head of a sceptic (we call this concussion). It has to be tapped a precise number of times, the number is decided by the current cost in pence of a avocado pear, this in scientific terms is known as the avocado number  -trust us it works!

We now have a homeopathic remedy inside the cleaner. The patient takes a tube from the cleaner applies it to their mouth * and vacuums out all those nasty miasmas  whilst simultaneously increasing the potency of the homeopathic preparation by yet further dilution.  But that’s not all! Dyson therapy removes harmful mercury vapour from your fillings, this is truly miraculous.

Until now vacuous homeopaths have argued that homeopathy  has no side effects effects. Sceptics have argued this is because it contains nothing does nothing and is worth nothing. Vacuous homeopaths have now found side effects, after all when you prepare the ultimate vacuum potencies we are dealing with the strongest medicine in the universe. Side effects include blisters of the lips and mouth, ruptured lungs and feelings of intense stupidity.

* Some experiments with Dyson therapy have been abandoned due to penile injury, but an exciting new avenue of research – anal Dyson therapy is being intensively studied, this combined with coffee enemas is an exciting new wake up call for homepathy. So far results have shown that homeopaths are full of shit.

Disclaimer: I do not own shares in Dyson, and am in no way associated with the company – Big Pharma wouldn’t let me. Other brands of vacuum cleaner are available.

AT FAP No5 (sent in by Norbert Aust)

German scientist succeeded in creating the ultimate homeopathic remedy: Vinum Christi C200! This remedy combines strong beliefs and ancient wisdom from christianity with the more recent scientific achievements of current homeopathy.

Details on the procedure are not clear yet, but the scientist (name known to the edotor) succeeded in building an entanglement with the the molecules of Our Lord’s last goblet of wine that today can be found in any glass of water. By banging his head on the wall he could successfully succuss just these molecules and could build a very powerful mother tincture. Further potentization yielded a very strong remedy, much more powerful than any of the current homeopathic alcoholic dilutions. It took only one tiny drop of this solution to turn a bottle of Scotch whisky into a very efficacious tincture outperforming any of our Lord’s wines or what you would expect of todays wines. In fact, the proving got a little out of control, but the effects could be witnessed nevertheless. It seems a perfect medicine for headaches, vertigo, nausea, general pain and feeling of being sick, difficulties in eye focus and speech, turns of general love and hate of the world in total. Many more symptoms expected to be found in further provings.

The scientist – after he recovered fronm the proving – made it a point, that the preparation of the mother tincture requires much experience and personality. The beginner might well end up entangled with the wrong molecules in his glass of water (like the donkey’s first pee after he carried our Lord to Jerusalem), which may lead to unpredictable results when proving the final compound.

Adress any inquiries for marketing of this medicine to the editor who will forward it to the scientist.

According to a recent comment by Dr Larry Dossey, sceptics are afflicted by “randomania,” “statisticalitis,” “coincidentitis,” or “ODD” (Obsessive Debunking Disorder). I thought his opinion was hilariously funny; it shows that this prominent apologist of alternative medicine who claims that he is deeply rooted in the scientific world has, in fact, understood next to nothing about the scientific method. Like all quacks who have run out of rational arguments, he resorts to primitive ad hominem attacks in order to defend his bizarre notions. It also suggests that he could do with a little scepticism himself, perhaps.

In case anyone wonders how the long-obsolete notions of vitalism, which Dossey promotes, not just survive but are becoming again wide-spread, they only need to look into the best-selling books of Dossey and other vitalists. And it is not just lay people, the target audience of such books, who are taken by such nonsense. Health care professionals are by no means immune to these remnants from the prescientific era.

A recent survey is a good case in point. It was aimed at exploring US student pharmacists’ attitudes toward complementary and alternative medicine (CAM) and examine factors shaping students’ attitudes. In total, 887 student pharmacists in 10 U.S. colleges/schools of pharmacy took part. Student pharmacists’ attitudes regarding CAM were quantified using the attitudes toward CAM scale (15 items), attitudes toward specific CAM therapies (13 items), influence of factors (e.g., coursework, personal experience) on attitudes (18 items), and demographic characteristics (15 items).

The results show a mean (±SD) score on the attitudes toward CAM scale of 52.57 ± 7.65 (of a possible 75; higher score indicated more favorable attitudes). There were strong indications that students agreed with the concepts of vitalism. When asked about specific CAMs, many students revealed positive views even on the least plausible and least evidence-based modalities like homeopathy or Reiki.

Unsurprisingly, students agreed that a patient’s health beliefs should be integrated in the patient care process and that knowledge about CAM would be required in future pharmacy practice. Scores on the attitudes toward CAM scale varied by gender, race/ethnicity, type of institution, previous CAM coursework, and previous CAM use. Personal experience, pharmacy education, and family background were important factors shaping students’ attitudes.

The authors concluded: Student pharmacists hold generally favorable views of CAM, and both personal and educational factors shape their views. These results provide insight into factors shaping future pharmacists’ perceptions of CAM. Additional research is needed to examine how attitudes influence future pharmacists’ confidence and willingness to talk to patients about CAM.

I find the overwhelmingly positive views of pharmacists on even over quackery quite troubling. One of the few critical pharmacists shares my worries and commented that this survey on CAM attitudes paints a concerning portrait of American pharmacy students. However, limitations in the survey process may have created biases that could have exaggerated the overall perspective presented. More concerning than the results themselves are the researchers’ interpretation of this data: Critical and negative perspectives on CAM seem to be viewed as problematic, rather than positive examples of good critical thinking.

One lesson from surveys like these is they illustrate the educational goals of CAM proponents. Just like “integrative” medicine that is making its ways into academic hospital settings, CAM education on campus is another tactic that is being used by proponents to shape health professional attitudes and perspectives early in their careers. The objective is obvious: normalize pseudoscience with students, and watch it become embedded into pharmacy practice.

Is this going to change? Unless there is a deliberate and explicit attempt to call out and push back against the degradation of academic and scientific standards created by existing forms of CAM education and “integrative medicine” programs, we should expect to see a growing normalizing of pseudoscience in health professions like pharmacy.

I have criticised pharmacists’ attitude and behaviour towards alternative medicine more often than I care to remember. I even contributed an entire series of articles (around 10; I forgot the precise number) to THE PHARMACEUTICAL JOURNAL in an attempt to stimulate their abilities to think critically about alternative medicine. Pharmacists could certainly do with a high dose of “randomania,” “statisticalitis,” “coincidentitis,” or “ODD” (Obsessive Debunking Disorder). In particular, pharmacists who sell bogus remedies, i.e. virtually all retail pharmacists, need to remember that

  • they are breaking their own ethical code
  • they are putting profit before responsible health care
  • by selling bogus products, they give credibility to quackery
  • they are risking their reputation as professionals who provide evidence-based advice to the public
  • they might seriously endanger the health of many of their customers

In discussions about these issues, pharmacists usually defend themselves and argue that

  • those working in retail chains cannot do anything about this situation; head office decides what is sold on their premises and what not
  • many medicinal products we sell are as bogus as the alternative medicines in question
  • other health care professions are also not perfect, blameless or free of fault and error
  • many pharmacists, particularly those not working in retail, are aware of this lamentable situation but cannot do anything about it
  • retail pharmacists are both shopkeepers and health care professionals and are trying their very best to cope with this difficult dual role
  • we usually appreciate your work and critical comments but, in this case, you are talking nonsense

I do not agree with any of these arguments. Of course, each single individual pharmacist is fairly powerless when it comes to changing the system (but nobody forces anyone to work in a chain that breaks the ethical code of their profession). Yet pharmacists have their professional organisations, and it is up to each individual pharmacist to exert influence, if necessary pressure, via their professional bodies and representatives, such that eventually the system changes. In all this distasteful mess, only one thing seems certain: without a groundswell of opinion from pharmacists, nothing will happen simply because too many pharmacists are doing very nicely with fooling their customers into buying expensive rubbish.

And when eventually something does happen, it will almost certainly be a slow and long process until quackery has been fully expelled from retail pharmacies. My big concern is not so much the slowness of the process but the fact that, currently, I see virtually no groundswell of opinion that might produce anything. For the foreseeable future pharmacists seem to have decided to be content with a role as shopkeepers who do not sufficiently care about healthcare-ethics to change the status quo.

A recent article  by a South African homeopath promoted the concept of homeopaths taking over the role of primary care practitioners. His argument essentially was that, in South Africa, homeopaths are well trained and thus adequately equipped to do this job responsibly. Responsibly, really? You find that hard to believe? Here are the essentials of his arguments including all his references in full. I think they are worth reading.

Currently, the Durban University of Technology (DUT) and the University of Johannesburg (UJ) offer degree’s in homoeopathy. This involves a 5-year full-time theoretical and practical training course, followed by a Master’s level research project. After fulfilment of these criteria, a Master’s Degree in Technology (Homoeopathy) is awarded. The course comprises of a strong core of medical subjects, such as the basic sciences of Anatomy, Physiology, Medical Microbiology, Biochemistry and Epidemiology, and the clinical sciences of Pathology and Diagnostics. This is complemented with subjects in Classical, Clinical and Modern Homoeopathy and Homoeopharmaceutics4,5

By law, any person practicing homoeopathy in South Africa must be registered with the Allied Health Professions Council of South Africa (AHPCSA). This is essential, as the Council ensures both medical and homoeopathic competency of practitioners, and that the activities of registered practitioners are closely monitored by the Professional Board. The purpose of the AHPCSA is to ensure that only those with legitimate qualifications of a high enough standard are registered and allowed to practice in South Africa, thus protecting the public against any fraudulent behaviour and illegal practitioners. Therefore, in order to ensure effective homoeopathic treatment, it is essential that any person wishing to prescribe homoeopathic medicine or practice homoeopathy in South Africa must be registered as a Homoeopathic Practitioner with the Allied Health Professions Council of South Africa. This includes conventional Medical Practitioners (dual registration is allowed for Medical Practitioners with both the Health Professions Council and AHPCSA)6,  as homoeopathy requires several years of training in order to apply effectively in clinical practice… 

Registration with the Council affords medico-legal rights similar to those of a medical professional, where treatment is limited to the scope of homoeopathic practice. Thus a homoeopath is firstly a trained diagnostician, and with successful registration with the Council, obtains the title Doctor. A homoeopath is trained and legally obliged to conduct a full medical history, a comprehensive clinical examination, and request further medical investigations, such as blood tests and X-rays, in order to fully assess patients. This is coupled with the ability to consult with specialist pathologists and other medical specialists when necessary, and refer a patient to the appropriate practitioner if the condition falls outside the scope of homoeopathic practice. A homoeopath may also legally issue a certificate of dispensation (‘Doctor’s note’) with appropriate evidence and within reason, and is deemed responsible for the diagnosis and treatment of patients under their care6. A homoeopath is not trained or licensed in any form of surgery, specialist diagnostics (e.g. colonoscopy or angiograms), cannot prescribe prescription medication and is not lawfully allowed to conduct intra-venous treatment of any kind. However, a registered homoeopath is licensed to use intra-muscular homoeopathic injectables in the treatment of various local or systemic complaints when necessary.

Conventional (allopathic) medicine generally targets specific biochemical processes with mostly chemically synthesised medication, in an attempt to suppress a symptom. However, in doing so, this usually negatively affects other biochemical reactions which results in an imbalance within the system. Homoeopathy, by contrast, seeks to re-establish a balance within the natural functioning of the body, restore proper function and results in the reduction or cessation of symptoms.  Homoeopathy therefore enables the body to self-regulate and self-heal, a process known as homeostasis that is intrinsic to every living organism.

Conventional medical treatment is by no means risk free. Iatrogenic (medically induced) deaths in the United States are estimated at 786 000 per year, deaths which are considered avoidable by medical doctors7,8. These figures put annual iatrogenic death in the American medical system above that of cardiovascular disease and cancer as the leading cause of death in that country9, a fact that is not widely reported! South African figures are not easily available, but it is likely that we have similar rates. Although conventional medications have a vital role, are sometimes necessary and can of-course be life-saving, all too often too many patients are put on chronic medication when there are numerous effective, natural, safe and scientifically substantiated options available….

According to the World Health Organisation (WHO), homeopathy is the second largest system of medicine in the world, and world-wide use continues to grow in developed and developing nations10. Homoeopathy is widely considered to be safe and effective, with both clinical and laboratory research providing evidence for the efficacy of homoeopathy11. As the range of potential conditions that homoeopathy can treat is almost limitless, and that treatment is not associated with adverse reactions, homoeopathy should be considered a first-line therapy for all ages. As homoeopaths in South Africa are considered primary health care practitioners, if a conventional approach is deemed necessary, and further diagnostics are required, your practitioner will not hesitate to refer you to the appropriate health care practitioner. Homeopathy is also used alongside conventional medicine and any other form of therapy, and should be seen as ‘complementary’ medicine and not ‘alternative’ medicine.

 

Conclusion

Homoeopathy is an approach that is widely considered to be safe, and when utilised correctly, can be effective for a wide range of conditions. As a primary health care practitioner, a homoeopath is able to handle all aspects of general practice and family health care, including diagnostics, case management and referral to other practitioners or medical specialists. A registered homoeopath is legally responsible to ensure the adequate treatment of their patients, and is accountable for all clinical decisions and advice. A registered homoeopath understands the role of conventional medicine, and will refer to the appropriate specialist in cases that fall outside the legal scope of practice.

I found this article extremely revealing and scary. It gives us an important glimpse into the way some or perhaps even most homeopaths think. They clearly believe that:

1) Their training is sufficient for them to become competent primary care professionals, i.e. clinicians who are the first port of call for sick people  to be diagnosed and treated effectively.

2) Homeopathy is scientifically proven to be efficacious for an ‘almost limitless’ range of conditions. Interestingly, not a single reference is provided to support this claim. Nevertheless, homeopath believe it, and that seems to be enough.

3) Homeopaths seem convinced that they perfectly understand real medicine; yet all they really do is to denounce it as one of the biggest killer of mankind.

4) The fact that homeopaths cannot prescribe real medicine is not seen as a hindrance to their role as primary care practitioner; if anything, homeopaths consider this to be an advantage.

5) Homeopaths view registration with some sort of governing body as the ultimate legitimation of their trade. Once such regulatory measures are in place, the need to support any of their claims with evidence is nil and void.

This article did remind me of the wry statement that ‘HOMEOPATHY IS TO MEDICINE WHAT THE CARPET INDUSTRY IS TO AVIATION’. Homeopaths truly live on a different planet, a planet where belief is everything and responsibility is an alien concept. I certainly hope that they will not take over planet earth in a hurry. If I imagine a world where homeopaths dominate primary care in the way it is suggested in this article, I start having nightmares. It seems to me that people who harbour ideas of this type are not just deluded to the point of madness but they are a danger to public health.

This post will probably work best, if you have read the previous one describing how the parallel universe of acupuncture research insists on going in circles in order to avoid admitting that their treatment might not be as effective as they pretend. The way they achieve this is fairly simple: they conduct trials that are designed in such a way that they cannot possibly produce a negative result.

A brand-new investigation which was recently vociferously touted via press releases etc. as a major advance in proving the effectiveness of acupuncture is an excellent case in point. According to its authors, the aim of this study was to evaluate acupuncture versus usual care and counselling versus usual care for patients who continue to experience depression in primary care. This sounds alright, but wait!

755 patients with depression were randomised to one of three arms to 1)acupuncture, 2)counselling, and 3)usual care alone. The primary outcome was the difference in mean Patient Health Questionnaire (PHQ-9) scores at 3 months with secondary analyses over 12 months follow-up. Analysis was by intention-to-treat. PHQ-9 data were available for 614 patients at 3 months and 572 patients at 12 months. Patients attended a mean of 10 sessions for acupuncture and 9 sessions for counselling. Compared to usual care, there was a statistically significant reduction in mean PHQ-9 depression scores at 3 and 12 months for acupuncture and counselling.

From this, the authors conclude that both interventions were associated with significantly reduced depression at 3 months when compared to usual care alone.

Acupuncture for depression? Really? Our own systematic review with co-authors who are the most ardent apologists of acupuncture I have come across showed that the evidence is inconsistent on whether manual acupuncture is superior to sham… Therefore, I thought it might be a good idea to have a closer look at this new study.

One needs to search this article very closely indeed to find out that the authors did not actually evaluate acupuncture versus usual care and counselling versus usual care at all, and that comparisons were not made between acupuncture, counselling, and usual care (hints like the use of the word “alone” are all we get to guess that the authors’ text is outrageously misleading). Not even the methods section informs us what really happened in this trial. You find this hard to believe? Here is the unabbreviated part of the article that describes the interventions applied:

Patients allocated to the acupuncture and counselling groups were offered up to 12 sessions usually on a weekly basis. Participating acupuncturists were registered with the British Acupuncture Council with at least 3 years post-qualification experience. An acupuncture treatment protocol was developed and subsequently refined in consultation with participating acupuncturists. It allowed for customised treatments within a standardised theory-driven framework. Counselling was provided by members of the British Association for Counselling and Psychotherapy who were accredited or were eligible for accreditation having completed 400 supervised hours post-qualification. A manualised protocol, using a humanistic approach, was based on competences independently developed for Skills for Health. Practitioners recorded in logbooks the number and length of sessions, treatment provided, and adverse events. Further details of the two interventions are presented in Tables S2 and S3. Usual care, both NHS and private, was available according to need and monitored for all patients in all three groups for the purposes of comparison.

It is only in the results tables that we can determine what treatments were actually given; and these were:

1) Acupuncture PLUS usual care (i.e. medication)

2) Counselling PLUS usual care

3) Usual care

Its almost a ‘no-brainer’ that, if you compare A+B to B (or in this three-armed study A+B vs C+B vs B), you find that the former is more than the latter – unless A is a negative, of course. As acupuncture has significant placebo-effects, it never can be a negative, and thus this trial is an entirely foregone conclusion. As, in alternative medicine, one seems to need experimental proof even for ‘no-brainers’, we have some time ago demonstrated that this common sense theory is correct by conducting a systematic review of all acupuncture trials with such a design. We concluded that the ‘A + B versus B’ design is prone to false positive results…What makes this whole thing even worse is the fact that I once presented our review in a lecture where the lead author of the new trial was in the audience; so there can be no excuse of not being aware of the ‘no-brainer’.

Some might argue that this is a pragmatic trial, that it would have been unethical to not give anti-depressants to depressed patients and that therefore it was not possible to design this study differently. However, none of these arguments are convincing, if you analyse them closely (I might leave that to the comment section, if there is interest in such aspects). At the very minimum, the authors should have explained in full detail what interventions were given; and that means disclosing these essentials even in the abstract (and press release) – the part of the publication that is most widely read and quoted.

It is arguably unethical to ask patients’ co-operation, use research funds etc. for a study, the results of which were known even before the first patient had been recruited. And it is surely dishonest to hide the true nature of the design so very sneakily in the final report.

In my view, this trial begs at least 5 questions:

1) How on earth did it pass the peer review process of one of the most highly reputed medical journals?

2) How did the protocol get ethics approval?

3) How did it get funding?

4) Does the scientific community really allow itself to be fooled by such pseudo-research?

5) What do I do to not get depressed by studies of acupuncture for depression?

Many reader of this blog will remember the libel case of the British Chiropractic Association (BCA) against Simon Singh. Simon had disclosed in a Guardian comment that the BCA was happily promoting bogus chiropractic treatments for 6 paediatric conditions, including infant colic. The BCA not only lost the case but the affair almost destroyed this strange organisation and resulted in an enormous reputational damage of chiropractors worldwide. In an article entitled AFTER THE STORM, the then-president of the BCA later described the defeat in his own words: “in 2009, events in the UK took a turn which was to consume the British Chiropractic Association (BCA) for two years and force the wider profession to confront key issues that for decades had kept it distanced from its medical counterparts and attracting ridicule from its critics…the BCA began one of the darkest periods in its history; one that was ultimately to cost it financially, reputationally and politically…The GCC itself was in an unprecedented situation. Faced with a 1500% rise in complaints, Investigating Committees were assembled to determine whether there was a case to answer…The events of the past two years have exposed a blind adherence to outdated principles amongst a small but significant minority of the profession. Mindful of the adage that it’s the squeaky wheel that gets the grease, the vocalism of this group has ensured that chiropractic is characterised by its critics as unscientific, unsafe and slightly wacky. Claims that the vertebral subluxation complex is the cause of illness and disease have persisted despite the three UK educational establishments advising the GCC that no evidence of acceptable quality exists to support such claims.”

Only a few years AFTER THE STORM, this story seems to have changed beyond recognition. Harald Walach, who is known to readers of this blog because I reported that he was elected ‘pseudo-scientist of the year’ in 2012, recently published a comment on the proceedings of the European Congress of Integrated Medicine where we find the following intriguing version of the libel case:

Mein Freund und Kollege George Lewith aus Southampton hatte einen Hauptvortrag über seine Überblicksarbeit über chiropraktische Interventionen für kleinkindliche Koliken vorgelegt. Sie ist ausgelöst worden durch die Behauptung, die Singh und Ernst vor einigen Jahren erhoben hatten, dass Chiropraktik gefährlich ist, dass es keine Daten dafür gäbe, dass sie wirksam sei und dass sie gefährliche Nebenwirkungen habe, speziell wenn sie bei Kindern angewendet würde. Die Chiropraktiker hatten den Wissenschaftsjournalisten Singh damals wegen Verleumdung verklagt und recht erhalten. George Lewith hatte dem Gericht die Expertise geliefert und nun seine Analyse auf Kinder ausgedehnt.

Kurz gefasst: Die Intervention wirkt sogar ziemlich stark, etwa eine Standardabweichung war der Effekt groß. Die Kinder schreien kürzer und weniger. Und die Durchforstung der Literatur nach gefährlichen Nebenwirkungen hatte keinen, wortwörtlich: nicht einen, Fall zu Tage gefördert, der von Nebenwirkungen, geschweige denn gefährlichen, berichtet hätte. Die Aufregung war seinerzeit dadurch entstanden, dass eine unqualifizierte Person einer zart gebauten Frau über den Rücken gelaufen ist und ihr dabei das Genick gebrochen hat. Die Presse hatte das ganze dann zu „tödlicher Nebenwirkung chiropraktischer Intervention“ aufgebauscht.

Oh, I almost forgot, you don’t read German? Here is my translation of this revealing text:

“My friend and colleague Geoorge Lewith from Southampton gave a keynote lecture on his review of chiropractic interventions for infant colic. This was prompted by the claim, made by Singh and Ernst a few years ago, that chiropractic was dangerous, that no data existed showing its effectiveness, and that it had dangerous side-effects, particularly for children. The chiropractors had sued the science journalist Singh for libel and won the case. George Lewith had provided the expert report for the court and has now extended his analysis on children.

To put it briefly: the intervention is even very effective; the effect-size is about one standard deviation. The children cry less long and more rarely. And the search of the literature for dangerous side-effects resulted in no – literally: not one – case of side-effects, not to mention dangerous ones. The fuzz had started back then because an unqualified person had walked over the back of a thin woman and had thus broken her neck. The press had subsequently hyped the whole thing to a “deadly side-effect of a chiropractic intervention”. (I am sorry for the clumsy language but the original is even worse.)

Now, isn’t that remarkable? Not only has the truth about the libel case been turned upside down, but also the evidence on chiropractic as a treatment for infant colic seems mysteriously improved; other reviews which might just be a bit more independent and objective come to the following conclusions:

The literature concerning this topic is surprisingly scarce, of poor quality and lack of convincing conclusions. With the present day data on this topic, it is impossible to say whether this kind of treatment has a significant effect.

The totality of this evidence fails to demonstrate the effectiveness of this treatment. It is concluded that the above claim is not based on convincing data from rigorous clinical trials.

And what should we make of all this? I don’t know about you, but I conclude that, for some apologists of alternative medicine, the truth is a rather flexible commodity.

In 1747, James Lind conducted what may well be the first documented controlled clinical trial in the history of medicine. He treated a small group of healthy sailors with a range of different remedies to see whether one of these regimen might be effective in preventing scurvy. The results showed that lemon and lime juice – effectively vitamin C – did the trick. This trial changed the world: it saved tens of thousands of lives, gave Britain the advantage at sea needed to become a dominant empire, and set medicine on the track to eventually become evidence-based.

Of course, Lind did not know that the effective principle in his lemon/lime juice was vitamin C. The Hungarian physiologist Albert Szent-Gyorgyi discovered vitamin C only ~200 years later and received the Nobel Prize for it in 1937. Since then, research has been buoyant, and vitamin C has been advocated for almost every condition one can think of. Looking at some of the claims made for it, I get the impression that more charlatans have jumped on the vitamin C band-waggon than the old vehicle can support. In alternative medicine, high-dose IV vitamin C is a popular variation of Lind’s concept, not least for the treatment of cancer.

Researchers from the NIH in the US surveyed attendees at annual CAM Conferences in 2006 and 2008, and determined sales of intravenous vitamin C by major U.S. manufacturers/distributors. They also queried practitioners for adverse effects, compiled published cases, and analyzed FDA’s Adverse Events Database. Of 199 survey respondents (out of 550), 172 practitioners had administered IV vitamin C to 11,233 patients in 2006 and to 8876 patients in 2008. The average dose was 28 grams every 4 days, with a mean of 22 treatments per patient. Estimated yearly doses used (as 25g/50ml vials) were 318,539 in 2006 and 354,647 in 2008. Manufacturers’ yearly sales were 750,000 and 855,000 vials, respectively. Common reasons for treatment included infection, cancer, and fatigue. Of 9,328 patients for whom data was available, 101 had adverse effects, mostly minor, including lethargy/fatigue in 59 patients, change in mental status in 21 patients and vein irritation/phlebitis in 6 patients. Publications documented serious adverse events, including two deaths. The FDA Adverse Events Database was uninformative.

The authors of this paper conclude that high dose IV vitamin C is in unexpectedly wide use by CAM practitioners. Other than the known complications of IV vitamin C in those with renal impairment or glucose 6 phosphate dehydrogenase deficiency, high dose intravenous vitamin C appears to be remarkably safe. Physicians should inquire about IV vitamin C use in patients with cancer, chronic, untreatable, or intractable conditions and be observant of unexpected harm, drug interactions, or benefit.

I find these results somewhat worrying. Desperate cancer patients are constantly being told that they can fight the disease with high-dose vitamin C, for instance on the >9 million (!) websites on this subject. One site, for instance, leaves little doubt about the efficacy of vitamin C as a treatment for cancer: First shown to be a powerful anti-cancer agent in 1971, it wasn’t until 20 years later that vitamin C started to be accepted by the mainstream medical profession. Eating a vitamin C-rich diet substantially reduces the risk of cancer, and high intakes – above 5000mg a day (the equivalent of 100 oranges) – substantially increases the life expectancy of cancer patients.

Statements like this one give false hope to cancer patients which is unethical and cruel and might hasten the death of many. The reality is quite different and provides little reason for such hope. Here are just a few conclusions from recent scientific analyses on this or closely related topics:

post-diagnosis vitamin C supplementation at the level observed in our population was not associated with survival

Evidence is insufficient to prove the presence or absence of benefits from use of multivitamin and mineral supplements to prevent cancer and chronic disease

We could not find evidence that antioxidant supplements prevent gastrointestinal cancers. On the contrary, they seem to increase overall mortality. The potential cancer preventive effect of selenium should be studied in adequately conducted randomised trial

The question whether the regular intake of high doses of vitamin C have a preventative effect for certain cancers is currently open. But there is no good reason to suggest that high dose IV vitamin C is an effective treatment for any cancer. To pretend otherwise, as so many alternative practitioners seem to do, is less than responsible – in fact, it is a hallmark for cancer quackery.

This post was inspired by a shiatsu-practitioner who recently commented on this blog. As I have not yet written a post about shiatsu, I think this might be a good occasion to do so. On one of the websites of the said practitioner – who claimed to have such amazing powers that hewould be locked up or worse“, if he made them public explains that Shiatsu is a form of natural healing therapy that promotes health through finger pressure along energy meridians or channels – like acupuncture but with no needles and all your clothes on. Shiatsu is a combination of ancient theories of oriental medicine and ‘energy’, with modern knowledge of anatomy and physiology. Shiatsu originated in Japan where it is officially recognised and parents teach their children to treat them. Shiatsu is one of the fastest growing areas of complementary therapy in the UK. Shiatsu is safe and non-invasive. Shiatsu is a holistic therapy which means your whole body is treated. Work on your energy channels promotes well-being at the physical and emotional levels and stimulates your natural self-healing processes. The application of pressure and gentle stretching helps relieve muscle tension, joint stiffness and to realign body structures. Contact with the energy pathways helps to correct imbalance in the functioning of internal organs and to re-balance the effects of emotional disturbance. You don’t have to be ill to enjoy Shiatsu, many people enjoy it simply because it is deeply relaxing.

I also looked up another of his websites and found that he claims to treat the following conditions:

  • Anger Management
  • Anxiety and Stress
  • Arthritis
  • Back pain
  • Bipolar disorder
  • Breathing/respiratory problems
  • Cancer
  • Confidence issues
  • Depression
  • Digestive Disorders
  • Eating Disorders
  • Eczema
  • Emotional Issues
  • Fears and Phobias
  • Headache
  • Indigestion
  • Infertility
  • Insomnia
  • Irritable bowel syndrome (IBS)
  • Joint Pain
  • Low energy/Lethargy
  • Low Self-Esteem
  • ME/Chronic Fatigue Syndrome
  • Migraine
  • Muscular Tension
  • Nausea and sickness
  • Nightmares
  • Obesity
  • Pain
  • Panic Attacks
  • Sciatica
  • Sexual problems
  • Sinus problems
  • Skin conditions
  • Sleeping problems
  • Social anxiety disorder
  • Spiritual Issues
  • Stiffness/Tension
  • Weight problems

Impressed by this list, I looked at similar sites and found that such extravagant claims seem more the rule than the exception in the world of shiatsu. Such therapeutic claims came as a big surprise to me: the last time we reviewed the evidence, we had concluded: NO CONVINCING DATA AVAILABLE TO SUGGEST THAT SHIATSU IS EFFECTIVE FOR ANY CONDITION.

But that was 5 years ago; perhaps there have been major advances since? To find out, I did a quick Medline search and – BINGO! – found a recent systematic review entitled “The evidence for Shiatsu: a systematic review of Shiatsu and acupressure“. It was authored by proponents of this therapy and can therefore not be suspected to be riddled with ‘anti-shiatsu bias’ (I just love the give-away title THE EVIDENCE FOR SHIATSU….!). These authors found that “Shiatsu studies comprised 1 RCT, three controlled non-randomised, one within-subjects, one observational and 3 uncontrolled studies investigating mental and physical health issues. Evidence was of insufficient quantity and quality” The only RCT included in their review was not actually a study of shiatsu but of a complex mixture of treatments including shiatsu for back and neck pain. No significant effects compared to standard care were identified in this study.

So, what does that tell us about shiatsu? It clearly tells us that it is an unproven therapy. And what does that say about shiatsu-practitioners who make multiple claims about treating serious conditions? I think I can leave it to my readers to answer this question.

I regularly used to ask alternative practitioners what diseases they are good at treating. In fact, we once ran an entire research project dedicated to this question and found that their own impressions were generally based on wishful thinking rather than on evidence. The libel case of the BCA versus Simon Singh then brought this issue into the focus of the public eye, and consequently several professional organisations of alternative practitioners seem to have advised their members to be cautious about making unsubstantiated therapeutic claims. This could have been an important step into the right direction – unless, of course, a clever trick had not been devised to bypass the need for evidence. Today, when I ask alternative practitioners ‘what do you treat effectively?’ I tend to get answers like:

  • Alternative practitioners, unlike conventional clinicians, do not treat diseases.
  • I treat the whole person, not just the disease.
  • I treat people and their specific set of signs and symptoms, rather than disease labels (this actually is a quote from the comments section of one of my recent posts).
  • I focus on the totality of the symptoms; disease labels are irrelevant in the realm of my therapy.
  • Chiropractors adjust subluxations which are the root cause for most diseases.
  • Acupuncturists re-balance life energies which is a precondition for healing to commence irrespective of the disease.
  • Homeopaths treat the totality of symptoms so that the patient’s vital force can do the healing.
  • etc. etc.

All of these statements are deeply rooted in the long obsolete notions of vitalism, i.e. the assumption that a vital energy flows in all living organisms and is responsible for our health irrespective of the disease we happen to suffer from. But what do the answers to my question ‘what do you treat?’ really mean? If we analyse the above responses critically, they seem to imply that:

  1. Conventional clinicians do not treat patients but merely disease labels.
  2. Alternative practitioners can successfully treat any disease or condition.

Ad 1 In my view, it is arrogant and grossly unfair to claim that alternative practitioners work holistically, while conventional health care professionals do not. I have pointed out repeatedly that any good medicine always has been and always will be holistic. High-jacking holism as a specific characteristic for alternative medicine is misleading and an insult to all conventional clinicians who do their best to practice good medicine.

Ad 2 By claiming that they treat the whole person irrespective of her disease, alternative practitioners effectively try to give themselves a ‘carte blanche’ for treating any disease or any condition or any symptom. If a child has asthma, a chiropractor will find a subluxation, adjust it with spinal manipulation, and claim that the child’s condition will improve as a consequence of his treatment – NEVER MIND THE EVIDENCE. If a person wants to give up smoking, an acupuncturist will use acupuncture to re-balance her yin and yang claiming that this intervention will make smoking cessation more successful – NEVER MIND THE EVIDENCE. If a patient suffers from cancer, a homeopath might find a remedy that promotes her vital energy claiming that the cancer will subsequently be cured – NEVER MIND THE EVIDENCE which in all of the three cases is negative.

The claim of alternative practitioners to not treat disease labels but the whole patient is doubtlessly attractive to consumers and it is also extremely good for business. On closer inspection, however, it turns out to be a distraction from the fact that alternative practitioners treat everything and anything, usually without the slightest evidence that their interventions generates more good than harm. It allows alternative practitioners to live in a fool’s paradise of quackery where they believe themselves to be protected from any challenges and demands for evidence.
