On this blog, I have discussed the lamentable quality of TCM products before (e. g. here, here and here). In a nutshell, far too high percentages of them are contaminated with toxic substances or adulterated with prescription drugs. It is no question: these deficits put many consumers at risk. Equally, there is no question that the problem has been known for decades.
For the Chinese exporters, such issues are a great embarrassment, not least because TCM-products are amongst the most profitable of all the Chinese exports. In the past, Chinese officials have tried to ignore or suppress the subject as much as possible. I presume they fear that their profits might be endangered by being open about the dubious quality of their TCM-exports.
Recently, however, I came across a website where unusually frank and honest statements of Chinese officials appeared about TCM-products. Here is the quote:
China is to unroll the fourth national survey of traditional Chinese medicine (TCM) resources to ensure a better development of the industry, said a senior health official…
With the public need for TCM therapies growing, the number of medicine resources has decreased and people have turned to the cultivated ones. However, due to a lack of standards, the cultivated TCM resources are sometimes less effective or even unsafe for human use, said Wang Guoqiang, director of the State Administration of TCM, at a TCM seminar held in Kunming, Yunnan Province in southwest China.
There is a pressing need to protect TCM resources, Wang said. “I’ve heard people saying that medicine quality will spell doom for the TCM industry, which I must admit, is no exaggeration,” he said.
The survey has been piloted in 922 counties in 31 provinces in China since 2011. According to its official website, it will draw a clear picture of the variety, distribution, storage and growth trends of TCM resources, including herbs, animals, minerals and synthetic materials.
TCM includes a range of traditional medical practices originating in China. It includes such treatments as herbal medicine, acupuncture, massage (tuina), exercise (qigong) and dietary therapy.
Although well accepted in the mainstream of medical care throughout East Asia, TCM is considered an alternative medical system in much of the western world and has been a source of controversy. A milestone in the recognition of TCM came when Chinese pharmaceutical chemist Tu Youyou won a Nobel Prize in 2015 for her discovery of Artemisinin, a medicinal herb, to help treat malaria.
END OF QUOTE
Surely, these are remarkable, perhaps even unprecedented statements by Chinese officials:
…cultivated TCM resources are sometimes less effective or even unsafe for human use…
…medicine quality will spell doom for the TCM industry…
Let’s hope that, after such words, there will be appropriate actions… finally.
It would be easy to continue this series on ‘tricks of the trade’ for quite a while. But this might get boring, and I have therefore decided to call it a day. So here is the last instalment (feel free to post further tricks that you may know of [in the comments section below]):
CRITICS DON’T UNDERSTAND
It is almost inevitable that, sooner or later, someone will object to some aspect of alternative medicine. In all likelihood, his or her arguments are rational and based on evidence. If that happens, the practitioner has several options to save his bacon (and income). One of the easiest and most popular is to claim that “of course, you cannot agree with me because you do not understand!”
The practitioner now needs to explain that, in order to achieve the level of expertise he has acquired, one has to do much more than to rationalise or know about science. In fact, one has to understand the subject on a much deeper level. One has to immerse oneself into it, open one’s mind completely and become a different human being altogether. This cannot be achieved by scientific study alone; it requires years of meditative work. And not everyone has the ability to go down this difficult path. It takes a lot of energy, insight and vision to become a true healer. A true Deepak Chopra is not born but trained through hard work, dedication and concentration.
Critics who disagree are really to be pitied. They fail to exist on quite the same level as those who ‘are in the know’. Therefore one must not get annoyed with those who disagree, they cannot understand because they have not seen the light.
My advice is to start thinking critically and read up about the NO TRUE SCOTSMAN FALLACY; this will quickly enable you to look beyond the charisma of these gurus and expose their charlatanry to the full.
RESEARCH IS BEING SUPRESSED
Some critics stubbornly insist on evidence for the therapeutic claims made by quacks. That attitude can be awkward for the alternative practitioner – because usually there is no good evidence.
Cornered in this way, quacks often come up with a simple but effective conspiracy theory: the research has been done and it has produced fabulous results, but it has been supressed by… well, by whoever comes to mind. Usually BIG PHARMA or ‘the scientific establishment’ have to be dragged out into the frame again.
According to this theory, the pharmaceutical industry (or whoever comes in handy) was so shaken by the findings of the research that they decided to make it disappear. They had no choice, really; the alternative therapy in question was so very effective that it would have put BIG PHARMA straight out of business for ever. As we all know BIG PHARMA to be evil to the core, they had no ethical or moral qualms about committing such a crime to humanity. Profits must come before charity!
My advice is to explain to such charlatans that such conspiracy theories do, in fact, merely prove is that the quack’s treatment is not effective against their prosecution complex.
CRITICS ARE BOUGHT AND CORRUPT
If critics of alternative medicine become threatening to the quackery trade, an easy and much-used method is to discredit them by spreading lies about them. If the above-mentioned ploy “they cannot understand” fails to silence the nasty critics, the next step must be to claim they are corrupt. Why else would they spend their time exposing quackery?
Many people – alternative practitioners included – can only think of financial motivations; the possibility that someone might do a job for altruistic reasons does not occur to them. Therefore, it sounds most plausible that the critics of alternative medicine are doing it for money – after all, the quacks also quack for money.
My advice to potential users of alternative medicine who are confused by such allegations: do your own research and find out for yourself who is bought by whom and who has a financial interest in quackery selling well.
EVEN NOBEL PRIZE WINNERS AGREE WITH US
It is true, there are some Nobel Prize winners who defend homeopathy or other bogus treatments. Whenever this happens, the apologists of alternative medicine have a field day. They then cite the Nobel laureate ad nauseam and imply that his or her views prove their quackery to be correct.
Little do they know that they are merely milking yet another classical fallacy and that such regrettable events merely demonstrate that even bright people can make mistakes.
My advice is to check what the Nobel laureate actually said – more often than not, it turns out that a much-publicised quote is, in fact, a misquote – and what his or her qualifications are for making such a statement; a Nobel Prize in literature, for instance, is not a sufficient qualification for commenting on healthcare issues.
AS I ALRADY SAID: IF YOU KNOW OF MORE ‘TRICKS OF THE QUACKARY TRADE’, PLEASE POST THEM BELOW.
This series of post is quite good fun – at least for me who is writing it. But I also hope that it is useful to those readers who are tempted to consult alternative practitioners. My intention is to stimulate people’s ability to think critically and to provide some sort of guide for patients which might help them in deciding which practitioners to avoid.
In this spirit, I now offer you the next instalment of three ‘tricks of the trade’:
NATURAL IS GOOD
Everyone working in advertising will confirm: the ‘natural label’ is a great asset for boosting sales of all sorts of things. Practitioners of alternative medicine have long appreciated this fact and exploited it to the best of their abilities. They stress the ‘naturalness’ of their treatments ad nauseam, and more often than not they use the term misleadingly.
For instance, there is nothing natural to thrust a patients spine beyond the physiological range of motion [chiropractic]; there is nothing natural in endlessly diluting and shaking remedies which may or may not have their origin in a natural substance [homeopathy]; there is nothing natural in sticking needles into the skin of patients [acupuncture].
Moreover, the notion of a benign ‘mother nature’ is naïvely misleading. Ask those who have been at sea during a storm or who have been struck by lightning.
My advice is to see through transparent marketing slogans and to tell the anyone who goes on about the ‘naturalness’ of his therapy to buzz off.
When one goes to a meeting of alternative practitioners, the term ‘energy’ is mentioned more often than at a board meeting of EDF. The difference is that the alternative brigade does not mean really energy when they speak of energy; they mean ‘vital force’ or one of the many related terms from other traditions.
Practitioners do prefer to use ‘energy’ because this sounds modern and impressive to many consumers. Crucially, it avoids disclosing how deeply steeped the therapists are in vitalism and vitalistic ideas. Whereas rational thinkers have discarded such concepts more than a century ago, alternative medicine advocates find it hard to do the same – if they did, there would be little else to underpin their various ‘philosophies’.
My advice is to avoid clinicians who are ‘vitalists’ because adhering to long obsolete concepts is a sure sign of dangerous backward thinking.
STIMULATING THE IMMUNE SYSTEM
‘Your immune system need stimulating!’ – how often have we heard that from practitioners of alternative medicine? By contrast, conventional clinicians are most reserved about such aims; they might try to stimulate the immune system in certain, rare circumstances. Quite often they need to achieve the opposite effect and use powerful drugs to suppress the immune system. But even when they aim at stimulating the immune system of a patient, they would not use any of the treatments alternative practitioners swear by.
How come? There are several reasons:
- The alternative ‘immune stimulants’ do not really stimulate the immune system.
- Stimulating the immune system is rarely a desirable therapeutic aim.
- Stimulating a normal immune system is hardly possible.
- For many of us, stimulating the immune system might even be a very risky business (if it were at all achievable).
My advice is to ask your practitioner precisely why he wants to stimulate your immune system. If he can give you a good reason, ask him to try stimulating his own immune system first and to show you the proof that his therapy can do such a thing.
TREAT A NON-EXISTING CONDITION
IT MUST GET WORSE BEFORE IT GETS BETTER
IT’S DUE TO THE POISONS YOUR DOCTOR GAVE YOU
A CURE TAKES A LONG TIME
Now it is time to disclose three more.
Alternative therapies are hugely diverse, but they nevertheless have a few characteristics in common. One is that many of their practitioners try to persuade their patients that they are being poisoned. This sounds odd, however, it is true.
Most alternative therapists tell their patients sooner or later that they need to ‘detox’ and, as it happens, their type of treatment is ideally suited to achieve this aim. Detox is short for detoxification which, in real medicine, is the term used for weaning addicts off their drugs. In alternative medicine, it is used as a marketing slogan.
Yes, detox, as used in alternative medicine, is nothing but a marketing slogan. I have several reasons for this statement:
- The poisons in question are never accurately defined. Instead, we hear only vague terminologies such as metabolic waste products or environmental toxins. The reason for that lack of precision is simple: once the poison is named, we could be able to measure it and test the efficacy of the treatment in question in eliminating it from the body. But this is the last thing these ‘detoxers’ want because we would soon establish how bogus their claims are.
- None of the alternative therapies claimed to detox our body take any toxin from us; all they do take from us is our cash.
- Our body has powerful organs and mechanisms to detoxify (skin, lungs, kidneys, liver). These take care of all the toxins we undoubtedly are exposed to. If any of these organs fail, we do not need homeopathic globoli or detoxifying diets, or electric foot baths or any other charlatanry; in this case, we are more likely to need an A&E department’s intensive care.
My advice is, as soon as you hear the word ‘detox’ from a quack, ask for your money back and go home.
THE TEST OF TIME
Another thing that many alternative therapies have in common is their age. They have almost all been around for hundreds, if not thousands of years. To the enthusiasts of alternative medicine, this means that these interventions have ‘stood the test of time’; they argue that acupuncture, for instance, would not be around any more, if it were not effective. They tell their patients, write in books and argue in debates that the age of their therapy is like a badge of approval from millions of people before us, a badge that surely weighs more that modern scientific studies (which tend to cast doubt on the effectiveness of the treatments in question).
This line of thinking has always puzzled me. We are talking of TECHNOLOGIES, health technologies, in fact. Would we argue that a hot air balloon is an older technology that an aeroplane and therefore better suited for transporting people from A to B? The fact that acupuncture was developed thousands of years ago might just mean that it was invented by relatively ignorant people who understood too little about the human body to create a truly effective intervention. And the fact that blood-letting was used for centuries (and thus killed millions), might teach us a lesson about the true value of ‘the test of time’ in medicine.
My advice is to offer leeches, blood-letting and mercury cures to those who try to persuade you that the test of time has meaningful therapeutic implications.
TREATING THE ROOT CAUSE OF THE DISEASE
Alternative practitioners often claim that, in conventional medicine, doctors only treat the symptoms of their patients, whereas they treat the root causes of the illness. I have often wondered where this assumption and the fierce conviction with which it is so often expressed come from. I have to conclude that the explanations are quite simple.
- This notion is the mantra that is being taught over and over again during the practitioners’ training. It even constitutes a central message of most ‘textbooks’ for the aspiring alternative practitioner.
- More importantly in the context of this post, the notion is a clever sales-trick. It sounds profound and logical to many consumers who lean towards alternative medicine. Crucially, it kills two flies with one stroke: it denigrates conventional healthcare and, at the same time, elevates alternative medicine.
The idea that alternative practitioners treat the root causes is based on the practitioners’ understanding of aetiology. If a traditional acupuncturist, for instance, is convinced that all disease is the expression of an imbalance of life-forces, and that needling acupuncture points will re-balance these forces thus restoring health, he must automatically assume that he is treating the root causes of any condition. If a chiropractor believes that all diseases are due to ‘subluxations’ of the spine, it must seem logical to him that spinal ‘adjustment’ is synonymous with treating the root cause of whatever complaint his patient is suffering from.
These are concepts that are deeply engrained into the minds of alternative practitioners. And they have one embarrassing feature in common: they are false! Some practitioners surely must know that; yet I have so far not met one who therefore would have stopped using it. The reason must be that, as a trick of the trade to increase his cash flow, it is invaluable.
My advice is to use your abilities for critical thinking, explain to the practitioner who tells you that he is going to treat the root causes of your condition that he is a quack, and look for a proper physician.
In part one, we have dealt with three common tricks used by quacks to convince the public to consult them and to keep coming back for more. It has been pointed out to me that some of these tricks are used not just by alternative practitioners but also by real physicians. This is, of course, absolutely true. A quack can be defined as “a person who dishonestly claims to have special knowledge and skill in some field, typically medicine.” Therefore real doctors can be real quacks, of course. I happen to have an interest mainly in alternative medicine; that’s why I write about these type of quacks (if it helps keeping you blood pressure within the limits of normal, I can tell you that I occasionally also published about quackery in mainstream medicine, for instance here).
Anyway, now it is time to continue this series of posts by discussing three further common deceptions used by quacks.
A CURE TAKES A LONG TIME
Imagine a scenario where, even after, several therapy sessions, a patient’s condition has not improved. Let’s assume the problem is back pain, and that it has not improved a bit despite the treatments and the money spent on it. Surely, many patients in such a situation are sooner or later going to give up. They will have had enough! And this is, of course, a serious threat to the practitioner’s cash flow.
Luckily, there is a popular ploy to minimize the risk: the practitioner merely has to explain that the patient’s condition has been going on for a very long time (if, in the above scenario, this were not the case, the practitioner would explain that the pain might be relatively recent but the underlying condition is chronic). This means that a cure will also have to take a very long time – after all, Rome was not built in one day!
This plea to carry on with the ineffective treatments despite any improvement of symptoms is usually not justifiable on medical grounds. It is, however, entirely justifiable on the basis of financial considerations of the practitioners. They rely on their patients’ regular payments and will therefore think of all sorts of means to achieve this aim.
Take my advice and see a clinician who can help you within a reasonable and predictable amount of time.
IT’S DUE TO THE POISONS YOUR DOCTOR GAVE YOU
In the pursuit of a healthy cash-flow, almost all means seem to be allowed – even the fabrication of the bogus notion that the reasons for the patient’s problem were the poisonous drugs prescribed by her doctor who, of course, is in cahoots with BIG PHARMA. Alternative medicine thrives on conspiracy theories, and the one of the evil ‘medical mafia’ is one of the all-time favourites. It enables scrupulous practitioners to instil a good dose of fear into the minds of their patients, a fear that minimises the risk of them returning to real medicine.
My advice is that alternative practitioners who habitually use this or any other conspiracy theory should be avoided at all costs.
The notion that alternative medicine takes care of the whole person is a most attractive and powerful ploy. Never mind that nothing could be further from being holistic than, for instance, diagnosing conditions by looking at a patient’s iris (iridology), or focussing on her spine (chiropractic, osteopathy), or massaging the soles of her feet (reflexology). And never mind that any type of good conventional medicine is by definition holistic. What counts is the label, and ‘holistic’ is a most desirable one, indeed. Nothing sells quackery better than holism.
Most alternative practitioners call themselves holistic and they rub the holism into the minds of their patients whenever and however they can. This insistence on holism has the added advantage that they have seemingly plausible excuses for their therapeutic failures.
Imagine a patient consulting a practitioner with depression and, even after prolonged treatment, her condition is unchanged. Even in such a situation, the holistic practitioner does not need to despair: he will point out that he never treats diagnostic labels but always the whole person. Therefore, the patient’s depression might not have changed, but surely other issues have improved… and, if the patient introspects a little, she might find that her appetite has improved, that her indigestion is better, or that her tennis elbow is less painful (some things always change given enough time). The holism of quacks may be a false pretence, but its benefits for the practitioner are obvious.
My advice: take holism from quacks with a pinch of salt.
We were recently informed that Americans spend more than US$ 30 billion per year on alternative medicine. This is a tidy sum by anyone’s standards, and we may well ask:
Why do so many people opt for alternative medicine?
The enthusiasts claim, of course, that this is because alternative medicine is effective and safe. As there is precious little data to support this claim, it is probably not the true answer. There must be other reasons, and I could name several. For instance, it could be due to consumers being conned by charlatans.
During the 25 years or so that I have been researching alternative medicine, I got the impression that there are certain ‘tricks of the trade’ which alternative practitioners use in order to convince the often all too gullible public. In this series of posts, I will present some of them.
Here are the first three:
TREAT A NON-EXISTING CONDITION
There is nothing better for committing a health fraud than to treat a condition that the patient in question does not have. Many alternative practitioners have made a true cult of this handy option. Go to a chiropractor and you will in all likelihood receive a diagnosis of ‘subluxation’. See a TCM practitioner and you might be diagnosed suffering from ‘chi deficiency’ or ‘chi blockage’ etc.
Each branch of alternative practitioners seem to have created their very own diagnoses, and they have one thing in common: they are figments of their imaginations. To arrive at such diagnoses, the practitioner would often use diagnostic techniques which have either been found to lack validity, or which have never been validated at all. Many practitioners appreciate all of this, of course, but it would be foolish of them to admit it – after all, these diagnoses earn them the bulk of their living!
The beauty of a non-existing diagnosis is that the practitioner can treat it, and treat it and treat it…until the client has run out of money or patience. Then, one day, the practitioner can proudly announce to his patient “you are completely healthy now”. This happens to be true, of course, because the patient has been healthy all along.
My advice for preventing to get fleeced in this way: make sure that the diagnosis given by an alternative practitioner firstly exists at all in the realm of real medicine and secondly is correct; if necessary ask a real healthcare professional.
As I just stated, practitioners like to treat and treat and treat conditions which simply do not exist. When – for whatever reason – this strategy fails, the next ‘trick of the trade’ is often to convince the patient of the necessity of ‘maintenance’ treatment. This term describes the regular treatment of an individual who is entirely healthy but who, according to the practitioner, needs regular treatments in order not to fall ill in future. The best example here is chiropractic.
Many chiropractors proclaim that maintenance treatment is necessary for keeping a person’s spine aligned – and only a well-serviced spine will keep all of our body’s systems working perfectly. It is like with a car: if you don’t service it regularly, it will sooner or later break down. You don’t want this to happen to your body, do you? To many ‘worried well’, this sounds so convincing that they actually fall for this scam. It goes without saying that the value of maintenance treatment is unproven.
My advice is to start running as soon as a practitioner mentions maintenance treatments.
IT MUST GET WORSE BEFORE IT GETS BETTER
Many patients fail to experience an improvement of their condition or even feel worse after receiving alternative treatments. Practitioners of alternative medicine love to tell these patients that this is normal because things have to get worse before they get better. They tend to call this a ‘healing crisis’. Like so many notions of alternative practitioners, the healing crisis is a phenomenon for which no or very little compelling evidence was ever produced.
Imagine a patient with moderately severe symptoms consulting a practitioner and receiving treatment. There are only three things that can happen to her:
- she can get better,
- she might experience no change at all,
- or she might get worse.
In the first scenario, the practitioner would obviously claim that his therapy is responsible for the improvement. In the second scenario, he might say that, without his therapy, things would have deteriorated. In the third scenario, he would tell his patient that the healing crisis is the reason for her experience. In other words, the myth of the healing crisis is little more than a ‘trick of the trade’ to make even these patients continue supporting the practitioner’s livelihood.
My advice: when you hear the term ‘healing crisis’, go and find a real doctor to help you with your condition.
The ACUPUNCTURE NOW FOUNDATION (ANF) have recently published a document that is worth drawing your attention to. But first I should perhaps explain who the ANF are. They state that “The Acupuncture Now Foundation (ANF) was founded in 2014 by a diverse group of people from around the world who were concerned about common misunderstandings regarding acupuncture and wanted to help acupuncture reach its full potential. Our goal is to become recognized as a leader in the collection and dissemination of unbiased and authoritative information about all aspects of the practice of acupuncture.”
This, I have to admit, sounds like music to my ears! So, I studied the document in some detail – and the music quickly turned into musac.
The document which they call a ‘white paper’ promises ‘a review of the research’. Reading even just the very first sentence, my initial enthusiasm turned into bewilderment: “It is now widely accepted across health care disciplines throughout the world that acupuncture can be effective in treating such painful conditions as migraine headaches, and low back, neck and knee pain, as well as a range of painful musculoskeletal conditions.” Any review of research that starts with such a deeply uncritical and overtly promotional statement, must be peculiar (quite apart from the fact that the ANF do not seem to appreciate that back and neck pain are musculoskeletal by nature).
As I read on, my amazement grew into bewilderment. Allow me to present a few further statements from this review (together with a link to the article provided by the ANF in support and a very brief comment by myself) which I found more than a little over-optimistic, far-fetched or plainly wrong:
“Male fertility, especially sperm production and motility, has also been shown to improve with acupuncture. In a recent animal study, electro-acupuncture was found to enhance germ cell proliferation. This action is believed to facilitate the recovery of sperm production (spermatogenesis) and may restore normal semen parameters in subfertile patients.”
The article supplied as evidence for this statement refers to an animal experiment using a model where sperm are exposed to heat. This has almost no bearing on the clinical situation in humans and does not lend itself to any clinical conclusions regarding the treatment of sub-fertile men.
“In a recent meta-analysis, researchers concluded that the efficacy of acupuncture as a stand-alone therapy was comparable to antidepressants in improving clinical response and alleviating symptom severity of major depressive disorder (MDD). Also, acupuncture was superior to antidepressants and waitlist controls in improving both response and symptom severity of post-traumatic stress disorder (PTSD). The incidence of adverse events with acupuncture was significantly lower than antidepressants.”
The review provided as evidence is wide open to bias; it was criticised thus: “the authors’ findings did not reflect the evidence presented and limitations in study numbers, sample sizes and study pooling, particularly in some subgroup analyses, suggested that the conclusions are not reliable”. Moreover, we need to know that by no means all reviews of the subject confirm this positive conclusion, for instance, this, this, or this one; all of the latter reviews are more up-to-date than the one provided by ANF. Crucially, a Cochrane review concluded that “the evidence is inconclusive to allow us to make any recommendations for depression-specific acupuncture”.
“A randomized controlled trial of acupuncture and counseling for patients presenting with depression, after having consulted their general practitioner in primary care, showed that both interventions were associated with significantly reduced depression at three months when compared to usual care alone.”
We have discussed the trial in question on this blog. It follows the infamous ‘A+B versus B’ design which cannot possibly produce a negative result.
Now, please re-read the first paragraph of this post; but be careful not to fall off your chair laughing.
There would be more (much more) to criticise in the ANF report but, I think, these examples are ENOUGH!
Let me finish by quoting from the ANF’s view on the future as cited in their new ‘white paper’: “Looking ahead, it is clear that acupuncture is poised to make significant inroads into conventional medicine. It has the potential to become a part of every hospital’s standard of care and, in fact, this is already starting to take place not only in the U.S., but internationally. The treatment is a cost-effective and safe method of relieving pain in emergency rooms, during in-patient stays and after surgery. It can lessen post-operative nausea, constipation and urinary difficulties, and have a positive impact on conditions like hypertension, anxiety and insomnia…
Driven by popular demand and a growing body of scientific evidence, acupuncture is beginning to be taken seriously by mainstream conventional medicine, which is incorporating it into holistic health programs for the good of patients and the future of health care. In order for this transition to take place most effectively, misunderstandings about acupuncture need to be addressed. We hope this white paper has helped to clarify some of those misunderstandings and encourage anyone with questions to contact the Acupuncture Now Foundation.”
My question is short and simple: IGNORANCE OR FRAUD?
Yesterday, I wrote about a new acupuncture trial. Amongst other things, I wanted to find out whether the author who had previously insisted I answer his questions about my view on the new NICE guideline would himself answer a few questions when asked politely. To remind you, this is what I wrote:
This new study was designed as a randomized, sham-controlled trial of acupuncture for persistent allergic rhinitis in adults investigated possible modulation of mucosal immune responses. A total of 151 individuals were randomized into real and sham acupuncture groups (who received twice-weekly treatments for 8 weeks) and a no acupuncture group. Various cytokines, neurotrophins, proinflammatory neuropeptides, and immunoglobulins were measured in saliva or plasma from baseline to 4-week follow-up.
Statistically significant reduction in allergen specific IgE for house dust mite was seen only in the real acupuncture group. A mean (SE) statistically significant down-regulation was also seen in pro-inflammatory neuropeptide substance P (SP) 18 to 24 hours after the first treatment. No significant changes were seen in the other neuropeptides, neurotrophins, or cytokines tested. Nasal obstruction, nasal itch, sneezing, runny nose, eye itch, and unrefreshed sleep improved significantly in the real acupuncture group (post-nasal drip and sinus pain did not) and continued to improve up to 4-week follow-up.
The authors concluded that acupuncture modulated mucosal immune response in the upper airway in adults with persistent allergic rhinitis. This modulation appears to be associated with down-regulation of allergen specific IgE for house dust mite, which this study is the first to report. Improvements in nasal itch, eye itch, and sneezing after acupuncture are suggestive of down-regulation of transient receptor potential vanilloid 1.
…Anyway, the trial itself raises a number of questions – unfortunately I have no access to the full paper – which I will post here in the hope that my acupuncture friend, who are clearly impressed by this paper, might provide the answers in the comments section below:
- Which was the primary outcome measure of this trial?
- What was the power of the study, and how was it calculated?
- For which outcome measures was the power calculated?
- How were the subjective endpoints quantified?
- Were validated instruments used for the subjective endpoints?
- What type of sham was used?
- Are the reported results the findings of comparisons between verum and sham, or verum and no acupuncture, or intra-group changes in the verum group?
- What other treatments did each group of patients receive?
- Does anyone really think that this trial shows that “acupuncture is a safe, effective and cost-effective treatment for allergic rhinitis”?
In the comments section, the author wrote: “after you have read the full text and answered most of your questions for yourself, it might then be a more appropriate time to engage in any meaningful discussion, if that is in fact your intent”, and I asked him to send me his paper. As he does not seem to have the intention to do so, I will answer the questions myself and encourage everyone to have a close look at the full paper [which I can supply on request].
- The myriad of lab tests were defined as primary outcome measures.
- Two sentences are offered, but they do not allow me to reconstruct how this was done.
- No details are provided.
- Most were quantified with a 3 point scale.
- Mostly not.
- Needle insertion at non-acupoints.
- The results are a mixture of inter- and intra-group differences.
- Patients were allowed to use conventional treatments and the frequency of this use was reported in patient diaries.
- I don’t think so.
So, here is my interpretation of this study:
- It lacked power for many outcome measures, certainly the clinical ones.
- There were hardly any differences between the real and the sham acupuncture group.
- Most of the relevant results were based on intra-group changes, rather than comparing sham with real acupuncture, a fact, which is obfuscated in the abstract.
- In a controlled trial fluctuations within one group must never be interpreted as caused by the treatment.
- There were dozens of tests for statistical significance, and there seems to be no correction for multiple testing.
- Thus the few significant results that emerged when comparing sham with real acupuncture might easily be false positives.
- Patient-blinding seems questionable.
- McDonald as the only therapist of the study might be suspected to have influenced his patients through verbal and non-verbal communications.
I am sure there are many more flaws, particularly in the stats, and I leave it to others to identify them. The ones I found are, however, already serious enough, in my view, to call for a withdrawal of this paper. Essentially, the authors seem to have presented a study with largely negative findings as a trial with positive results showing that acupuncture is an effective therapy for allergic rhinitis. Subsequently, McDonald went on social media to inflate his findings even more. One might easily ask: is this scientific misconduct or just poor science?
I would be most interested to hear what you think about it [if you want to see the full article, please send me an email].
On this blog, I have repeatedly tried to explain why integrative (or integrated) medicine is such a deceptive nonsense; see for instance here, here and here. Today, I have reason to make another attempt: The International Congress on Integrative Medicine & Health.
In 2012, I published an analysis of the ‘3rd European Congress of Integrated Medicine’ which had taken place in December 2010 in Berlin (in Europe they call it ‘integrated’ and in the US ‘integrative’ medicine). For this purpose, I simply read all the 222 abstracts and labelled them according to their contents. The results showed that the vast majority were on unproven alternative therapies and none on conventional treatments.
The abstracts from the International Congress on Integrative Medicine & Health (ICIMH, Green Valley Ranch Resort, Las Vegas, Nevada, USA, May 17–20, 2016) which were just published provide me with the opportunity to check whether this situation has changed. There were around 400 abstracts, and I did essentially the same type of analysis (attributing one subject area to each abstract). And what a tedious task this was! I spotted just two articles of interest, and will report about them shortly.
This time I also assessed whether the conclusions of each paper were positive (expressing something favourable about the subject at hand), negative (expressing something negative about the subject at hand) or neither of the two (surveys, for instance, rarely show positive or negative results).
Here are the results: mind-body therapies were the top subject with 49 papers, followed by acupuncture (44), herbal medicine (37), integrative medicine (36), chiropractic and other manual therapies (26), TCM (19), methodological issues (16), animal and other pre-clinical investigations (15) and Tai Chi (5). The rest of the abstracts were on a diverse array of other subjects. There was not a single paper on a conventional therapy and only 4 focussed on risk assessments.
The 36 articles on integrative medicine deserve perhaps a special mention. The majority of these papers were about using alternative therapies as an add-on to conventional care. They focussed on the alternative therapies used and usually concluded that this ‘integration’ was followed by good results. None of these papers discussed integrative medicine and its assumptions critically, and none of these investigations cast any doubt about the assumption that integrative medicine is a positive thing.
I should also mention that my attributions of the subject areas were not always straight forward. I allowed myself only one subject per paper, but there were, of course, many that could be categorised in more than one subject area ( for instance, a paper on an herbal medicine might be in that category, or in TCM or in pre-clinical). So I tried to attribute the subject that seemed to dominate the abstract in question.
My analysis according to the direction of the conclusions was equally revealing: I categorised 260 papers as positive, 5 as negative and 116 as neither of the two. That means for every negative result there were 52 positive ones. I find this most remarkable.
Essentially, my two analyses of conference abstracts published 6 years apart show the same phenomenon: on the ‘scientific level’, integrative medicine is not about the ‘best of both worlds’ (i. e. the best alternative medicine has to offer integrated with the best conventional medicine offers) – the slogan by which advocates of integrative medicine usually try to ‘sell’ their dubious approach to us. It is almost exclusively about alternative therapies which advocates of integrative medicine aim to smuggle into mainstream healthcare. Critical analysis seems to be unwelcome in this area, and – perhaps worse of all – in the last 6 years, there does not seem to have been any improvement.
And that’s just on the ‘scientific level’, as I said. If you wonder what is happening on the ‘practical level’, you will find that, in the realm of integrative medicine, every quackery under the sun is being promoted at often exorbitant prices to the often gullible and always unsuspecting public. If you don’t believe me, search for ‘integrative medicine clinic’ on the Internet; I promise, you will be surprised!
Personally, I am sometimes amused by the sheer idiocy of all this, but more often I am enraged and ask myself:
- Why are we allowing quackery to make such a spectacular come-back?
- Why is hardly anyone voicing strong objections?
- Is it not our ethical duty to do something about it and try to prevent the worse?
Reiki is one of the most popular types of ‘energy healing’. Reiki healers believe to be able to channel ‘healing energy’ into patients’ body thus enabling them to get healthy. If Reiki were not such a popular treatment, one could brush such claims aside and think “let the lunatic fringe believe what they want”. But as Reiki so effectively undermines consumers’ sense of reality and rationality, I feel I should continue informing the public about this subject – despite the fact that I have already reported about it several times before, for instance here, here, here, here, here and here.
A new RCT, published in a respected journal looks interesting enough for a further blog-post on the subject. The main aim of the study was to investigate the effectiveness of two psychotherapeutic approaches, cognitive behavioural therapy (CBT) and a complementary medicine method Reiki, in reducing depression scores in adolescents. The researchers from Canada, Malaysia and Australia recruited 188 adolescent depressed adolescents. They were randomly assigned to CBT, Reiki or wait-list. Depression scores were assessed before and after 12 weeks of treatments/wait list. CBT showed a significantly greater decrease in Child Depression Inventory (CDI) scores across treatment than both Reiki (p<.001) and the wait-list control (p<.001). Reiki also showed greater decreases in CDI scores across treatment relative to the wait-list control condition (p=.031). Male participants showed a smaller treatment effects for Reiki than did female participants. The authors concluded that both CBT and Reiki were effective in reducing the symptoms of depression over the treatment period, with effect for CBT greater than Reiki.
I find it most disappointing that these days even respected journals publish such RCTs without the necessary critical input. This study may appear to be rigorous but, in fact, it is hardly worth the paper it was printed on.
The results show that Reiki produced worse results than CBT. That I can well believe!
However, the findings also suggest that Reiki was nevertheless “effective in reducing the symptoms of depression”, as the authors put it in their conclusions. This statement is misleading!
It is based on the comparison of Reiki with doing nothing. As Reiki involves lots of attention, it can be assumed to generate a sizable placebo effect. As a proportion of the patients in the wait list group are probably disappointed for not getting such attention, they can be assumed to experience the adverse effects of their disappointment. The two phenomena combined can easily explain the result without any “effectiveness” of Reiki per se.
If such considerations are not fully discussed and made amply clear even in the conclusions of the abstract, it seems reasonable to accuse the journal of being less than responsible and the authors of being outright misleading.
As with so many papers in this area, one has to ask: WHERE DOES SLOPPY RESEARCH END AND WHERE DOES SCIENTIFIC MISCONDUCT BEGIN?
