Many hard-nosed sceptics might claim that there is no herbal treatment for upper respiratory infections that makes the slightest difference difference. But is this assumption really correct?
According to my own research of 2004, it is not. Here is the abstract of our systematic review:
Acute respiratory infections represent a significant cause of over-prescription of antibiotics and are one of the major reasons for absence from work. The leaves of Andrographis paniculata (Burm. f.) Wall ex Nees (Acanthaceae) are used as a medicinal herb in the treatment of infectious diseases. Systematic literature searches were conducted in six computerised databases and the reference lists of all papers located were checked for further relevant publications. Information was also requested from manufacturers, the spontaneous reporting schemes of the World Health Organisation and national drug safety bodies. No language restrictions were imposed. Seven double-blind, controlled trials (n = 896) met the inclusion criteria for evaluation of efficacy. All trials scored at least three, out of a maximum of five, for methodological quality on the Jadad scale. Collectively, the data suggest that A. paniculata is superior to placebo in alleviating the subjective symptoms of uncomplicated upper respiratory tract infection. There is also preliminary evidence of a preventative effect. Adverse events reported following administration of A. paniculata were generally mild and infrequent. There were few spontaneous reports of adverse events. A. paniculata may be a safe and efficacious treatment for the relief of symptoms of uncomplicated upper respiratory tract infection; more research is warranted.
A. Paniculata (Burm.f.) Wall ex Nees (Acanthaceae family), also known as nemone chinensi, Chuān Xīn Lián, has traditionally been used in Indian and Chinese herbal medicine mostly as an antipyretic for relieving and reducing the severity and duration of symptoms of common colds and alleviating fever, cough and sore throats, or as a tonic to aid convalescence after uncomplicated respiratory tract infections. The active constituents of A. paniculata include the diterpene, lactones commonly known as the andrographolides which have shown anti-inflammatory, antiviral, anti-allergic, and immune-stimulatory activities. A. Paniculata has also been shown, in vitro, to be effective against avian influenza A (H9N2 and H5N1) and human influenza A H1N1 viruses, possibly through blocking the binding of viral hemagglutinin to cells, or by inhibiting H1N1 virus-induced cell death.
But our systematic review was published 14 years ago!
We need more up-to-date information!
And I am pleased to report that a recent paper provided exactly that.
This systematic review included published and unpublished RCTs. Quasi-RCTs, crossover trials, controlled before and after studies, interrupted time series (ITS) studies, and non-experimental studies were not included due to their potential high risk of bias.
Thirty-three trials involving 7175 patients with ARTIs were included. Their methodological quality was restricted as randomisation was not well documented; 73% of the trials included were not blinded; where ITT analysis were performed, loss to follow-up data were counted as no effect; and most trials were published without a protocol available.
Findings suggested limited but consistent evidence that A. Paniculata improved cough and sore throat when compared with placebo. A. Paniculata (alone or plus usual care) had a statistically significant effect in improving overall symptoms of ARTIs when compared to placebo, usual care, and other herbal therapies. A. Paniculata in pillule tended to be more effective in improving overall symptoms over A. Paniculata in tablet. Evidence also suggested that A. Paniculata (alone or plus usual care) shortens the duration of cough, sore throat and sick leave/time to resolution when compared versus usual care. Reduction in antibiotic usage was seldom evaluated in the included trials.
The authors concluded that A. Paniculata appears beneficial and safe for relieving ARTI symptoms and shortening time to symptom resolution. However, these findings should be interpreted cautiously owing to poor study quality and heterogeneity. Well-designed trials evaluating the effectiveness and potential to reduce antibiotic use of A. Paniculata are warranted.
In case you wonder about conflicts of interest: there were none with my 2004 paper, and the authors of the new review state that this paper presents independent research funded by the National Institute for Health Research School for Primary Care Research (NIHR SPCR). The views expressed are those of the author(s) and not necessarily those of the NIHR, the NHS or the Department of Health.
Yes, the RCTs are not all of top quality.
And yes, the effect size is not huge.
But maybe – just maybe – we do have here an alternative therapy that does help against a condition for which conventional drugs are fairly useless!?!
This is a question most clinicians must have asked themselves. The interest of patients in this area is enormous, and many do seek advice from their doctor, nurse, pharmacist, midwife etc. In a typical scenario, a patient might plug up her courage (yes, for many it does take courage) and ask:
What about therapy xy for my condition? My friend suffers from the same problem, and she says the treatment works very well.
The way I see it, there are essentially 4 options for formulating a reply:
1. Uncompromisingly negative
4. Uncritically promotional
Let me explain and address these 4 options in turn.
1. Uncompromisingly negative
I know that it can be tempting to be wholly dismissive and simply state that all alternative medicine is rubbish; if it were any good, it would have been adopted by conventional medicine. Therefore, alternative medicine is never an alternative; it is by definition implausible, ineffective and often dangerous.
Even if all of this were true, the uncompromisingly negative approach is not helpful, in my experience. Patients need and deserve some empathy and understanding of their position. If we brusque them, they feel insulted and go elsewhere. Not only would we then lose a patient, but we would run a high risk of exposing her to a practitioner who promotes quackery. The disservice seems obvious.
Clinicians might consider their patient’s question and reply to it by explaining what the current best available evidence tells us about the therapy in question. This can be done with empathy and compassion. For instance (if that is true), the clinician can explain that the treatment in question lacks a scientific basis, that it has nevertheless been tested in clinical trials which sadly do not show that it works. Crucially, the clinician should subsequently explain what effective treatments do exist and discuss a viable treatment plan with the patient.
The problem with this approach is that many, if not most conventional clinicians are fairly clueless about the evidence as it relates to the plethora of alternative therapies. Therefore, an honest discussion around the current best evidence is often difficult or impossible.
This is the approach many clinicians today use as a default position. They basically tell their patient that there is not a lot of evidence for the treatment in question. However, it seems harmless, and therefore – if the patient is really keen on going down this route – why not? This type of response is, I fear, given regardless of the therapy in question and it largely ignores the evidence – some alternative treatments do work, some don’t, some are fairly safe, some aren’t.
Condoning alternative medicine in this way gives the impression of being ‘open-minded’ and ‘patient-centred’. It has the considerable advantage that it does not require any hard work, such as informing oneself about the current best evidence. It’s disadvantage is that it neither correct nor ethical.
4. Uncritically promotional
Many clinicians go even one decisive step further. Under the banner of ‘integrative medicine’, they openly recommend using ‘the best of both worlds’ as being ‘holistic’, ’empathetic’, ‘patient-centred’, etc. By this, they usually mean employing as many unproven or disproven treatments as alternative medicine has to offer.
This approach gives the impression of being ‘modern’ and in tune with the wishes of patients. Its disadvantages are, however, obvious. Introducing bogus treatments into clinical routine can only render it less effective, more expensive, and less safe. Integrative medicine is therefore not in the best interest of patients and arguably unethical.
So, how should we advise patients on alternative medicine? I know what I would say and probably most of my readers can guess. But I do not want to prejudge the issue; I prefer to hear your views, please.
Traditional Chinese Medicine (TCM) is popular, not least because it is heavily marketed and thus often perceived as natural and safe. But is this assumption true?
This study analysed liver tests before and following treatment with herbal Traditional Chinese Medicine (TCM) in order to evaluate the risk of liver injury. Patients with normal values of alanine aminotransferase (ALT) as a diagnostic marker for ruling out pre-existing liver disease were enrolled in a prospective study of a safety program carried out at the First German Hospital of TCM from 1994 to 2015. All patients received herbal products, and their ALT values were reassessed 1-3 d prior to discharge. To evaluate causality for suspected TCM herbs, the Roussel Uclaf Causality Assessment Method (RUCAM) was used.
The report presents data of 21470 patients. ALT ranged from 1 × to < 5 × upper limit normal (ULN) in 844 patients (3.93%) and suggested mild or moderate liver adaptive abnormalities. A total of 26 patients (0.12%) experienced higher ALT values of ≥ 5 × ULN (300.0 ± 172.9 U/L, mean ± SD). Causality for TCM herbs was estimated to be probable in 8/26 patients, possible in 16/26, and excluded in 2/26 cases.
Compared with the large TCM study cohort, patients in the liver injury study cohort were older and contained a higher percentage of women, whereas the duration of the hospital stay was similar in both cohorts. The TCM herbs were rarely applied mostly as mixtures consisting of several herbs adding up to 35 different drugs during the patients’ four-week stay. The daily dosage was 95 ± 30 g and thus slightly higher than in the TCM study cohort. Among the many herbal TCM used by the 26 patients in the liver injury cohort, Bupleuri radix and Scuterllariae radix were the two TCM herbs most frequently implicated in liver injury, with variable RUCAM-based causality gradings. Most of the patients received one to six TCM drugs that were associated with potential liver injury as evidenced from the scientific literature, e.g., one patient (case 8) received six potentially hepatotoxic herbal TCM drugs during their hospital stay.
The authors concluded that in 26 (0.12%) of 21470 patients treated with herbal TCM, liver injury with ALT values of ≥ 5 × ULN was found, which normalized shortly following treatment cessation, also substantiating causality.
In the discussion section of the paper, the authors comment that the use of TCM is widely considered less risky as compared with synthetic drugs, although data on direct comparisons are not available in support of this view. Populations using herbal TCM, drugs, either alone, or combined experience more drug-induced liver injury (DILI) than herb-induced liver injury (HILI), possibly due to a higher use of drugs. Valid data of incidence and prevalence of HILI caused by TCM herbs are lacking, and respective data cannot be derived from the present study.
This study is most valuable, in my view. Its strength is clearly the huge sample size. Top marks for the authors for publishing it!
Having said that, we need to take the incidence figures with a pinch of salt, I think. In reality they could be much higher because:
- other settings will not be as tightly supervised as the unusual hospital setting;
- in most other situations the quality of the Chinese herbs might be less controlled;
- there could be adulteration;
- there could be contamination.
The ‘elephant in the room’ obviously is the inevitable question about benefit. Like any other treatment, TCM cannot be judged on the basis of its risk but must be evaluated according to its risk/benefit balance. I realise that this was not the subject of the present study, but it is nevertheless crucial: do the benefits of TCM outweigh its risks?
I am not aware that this is the case (but more than willing to consider any sound evidence readers might supply). More importantly, I am not aware of good evidence to show that, for any condition, TCM would be superior in terms of risk/benefit balance than conventional options. This is not a trivial issue: clinicians have the ethical obligation to apply the best (the one with the most positive risk/benefit balance) treatment to their patients.
If I am right, then TCM should not be used in therapeutic routine in or outside hospitals.
If I am right, the ‘First German Hospital of TCM‘ should close asap; it would be violating fundamental ethical principles.
If I am right, the debate about the risks of TCM is almost irrelevant because we simply should not use it.
Or did I misunderstand something here?
What do you think?
On their website, the British Homeopathic Association (BHA) have launched their annual winter appeal. Its theme this year is ‘building a better future for homeopathy’. The appeal is aimed at the following specific goals:
- Continuously fighting to retain NHS services in the UK by supporting local patients & groups and providing swift media responses employing experts in areas such as media, politics, law and reputation management for ultimate effectiveness. Currently undertaking a legal challenge to NHS England
- Establishing charitable homeopathic clinics throughout the UK, with clinics currently in Norwich, York, Bath, Edinburgh and looking at developing other clinics in Liverpool, Wales, Oxford and London in 2018.
- Making further investment to enhance our digital presence and promotion of key messages.
- Continuoustly improving our website to make it the place for information on homeopathy from finding practitioners to finding the latest Health & Homeopathy online.
- Investing in research and education to keep homeopathy strong in the long term, increasing the number of healthcare professionals using homeopathy in their everyday practice.
- Taking homeopathy to the people and growing our community of supporters with public events, local events and national promotion.
I have to say, I find this almost touching in its naivety. I imagine another lobby group, say the cigarette industry, launching a winter appeal: BUILDING A BETTER FUTURE FOR CIGARETTES.
Do I hear you object?
Cigarettes are unhealthy and not a medical treatment!!!
Quite so! Homeopathy is also unhealthy and not a medical treatment, I would argue. Sure, highly dilute homeopathics do not kill you, but homeopathy easily can. We have seen this on this blog many times. Homeopathy kills when it is advocated and consequently used as an alternative therapy for a life-threatening disease; there is no question about it. And there also is no question about the fact that this happens with depressing regularity. If you doubt it, just read some of my previous posts on the subject.
In any case, an appeal by a medical association should not be for its own benefit (homeopathy); it should be for patients (patients tempted to try homeopathy), I would suggest. So, lets design the goals of an appeal for patients along the lines of the above appeal – except our appeal has to actually be in the best interest of vulnerable patients.
Here we go:
- Continually fighting to stop homeopathy on the NHS. As homeopathy does not generate more good than harm (no ineffective therapy can ever do that), we have a moral, legal and ethical duty to use our scarce resources such that they create the maximum benefit; and this means we cannot use them for homeopathy.
- Establishing charitable organisations that educate the public about science and evidence. Too many consumers are still falling victim to the pseudo-science of charlatans who mislead people for their own profit.
- Making further investments to combating the plethora of unethical misinformation by self-interested quacks and organisations many of which even have charitable status.
- Continually improving websites that truthfully inform the public, politicians, journalists and others about medicine, science and healthcare.
- Investing in research and education to keep science and evidence-based medicine strong, for the benefit of vulnerable patients and in the interest of progress.
- Taking the science agenda to the people and growing the community of science-literate supporters on a local, national and international level.
As I had to follow the lines of the BHA, these goals are regrettably not perfect – but I am sure they are a whole lot better than the BHA original!
This survey assessed chiropractic (DC) and naturopathic “doctors”‘ (ND) knowledge, attitudes, and behaviour with respect to the pediatric patients in their practice. Cross-sectional surveys were developed in collaboration with DC and ND educators. Surveys were sent to randomly selected DCs and NDs in Ontario, Canada in 2004, and a national online survey was conducted in 2014. Data were analyzed using descriptive statistics, t-tests, non-parametric tests, and linear regression.
Response rates for DCs were n = 172 (34%) in 2004, n = 553 (15.5%) in 2014, and for NDs, n = 171 (36%) in 2004, n = 162 (7%) in 2014. In 2014, 366 (78.4%) of DCs and 83 (61%) of NDs saw one or more paediatric patients per week. Paediatric training was rated as inadequate by most respondents in both 2004 and 2014, with most respondents (n = 643, 89.9%) seeking post-graduate training by 2014. About half of DCs (51.7% in 2004, 49.2% in 2014) and one fifth of NDs (21% in 2004 and 23% in 2014) reported they received no hands-on clinical paediatric training. Only a minority of practitioners felt their hands-on paediatric training was adequate (somewhat or very) for their needs: DCs: 10.6% in 2004, 15.6% in 2014; NDs: 10% in 2004 and 19% in 2014. Respondents’ comfort in treating children and youth is based on experience and post-graduate training. Both DCs and NDs that see children and youth in their practices address a broad array of paediatric health concerns, from well child care and preventative health, to mild and serious illness.
The authors included two ‘case studies’ of conditions frequently treated by DCs and NDs:
Case study 1: colic
DC practitioners’ primary treatment focus (314 respondents) would be to use spinal manipulation (78.3%) if physical assessment suggests utility, diet changes (14.6% for child, 6.1% for mom if breast feeding), and massage (16.9%). ND practitioners (95 respondents) would assess and treat primarily with diet changes (62% for child including prescribing probiotics; 48% for mom if breast feeding), homeopathy (46%), weak herbal or tea preparations (19%), and use topical castor oil (packs or massage) (18%). In 2014, 65.9% of DCs and 59% of NDs believe (somewhat or very much) that concurrent treatment by a medical practitioner would be of benefit; 64.0% of DCs and 60% of NDs would refer the patient to another health care practitioner (practitioner type not specified).
Case study 2: acute otitis media
In 2014, almost all practitioners identified this as otitis media (in 2004, the DCs had a profession-specific question); DCs were more cautious about the value of their care for it relative to the NDs (DCs, 46.2% care will help patient very much, NDs, 95%). For treatment, DCs would primarily use spinal manipulation (98.5%) if indicated after assessment, massage (19.5%), dietary modifications (17.6%), and 3.8% would specifically refer to an MD for an antibiotic prescription. ND-preferred treatments were NHP products (79%), dietary modifications (66%), ear drops (60%), homeopathic remedies (18%), and 10% would prescribe antibiotics right away or after a few days. In 2014, 86.3% of DCs and 75% of NDs believe the patient would benefit (somewhat or very much) from concurrent treatment by a conventional medical practitioner; 81.7% of DCs and 58% of NDs would refer the patient to another health care provider.
The authors concluded that although the response rate in 2014 is low, the concerns identified a decade earlier remain. The majority of responding DCs and NDs see infants, children, and youth for a variety of health conditions and issues, but self-assess their undergraduate paediatric training as inadequate. We encourage augmented paediatric educational content be included as core curriculum for DCs and NDs and suggest collaboration with institutions/organizations with expertise in paediatric education to facilitate curriculum development, especially in areas that affect patient safety.
I find these data positively scary:
- Despite calling themselves ‘doctors’, they are nothing of the sort.
- DCs and NCs are not adequately educated or trained to treat children.
- They nevertheless often do so, presumably because this constitutes a significant part of their income.
- Even if they felt confident to be adequately trained, we need to remember that their therapeutic repertoire is wholly useless for treating sick children effectively and responsibly.
- Therefore, harm to children is almost inevitable.
- To this, we must add the risk of incompetent advice from CDs and NDs – just think of immunisations.
The only conclusion I can draw is this: chiropractors and naturopaths should keep their hands off our kids!
This overview by researchers from that Arthritis Research UK Primary Care Centre, Research Institute for Primary Care & Health Sciences, Keele University, UK, was aimed at summarising the current best evidence on treatment options for 5 common musculoskeletal pain presentations: back, neck, shoulder, knee and multi-site pain. Reviews and studies of treatments were considered of the following therapeutic options: self-management advice and education, exercise therapy, manual therapy, pharmacological interventions (oral and topical analgesics, local injections), aids and devices, other treatments (ultrasound, TENS, laser, acupuncture, ice / hot packs) and psychosocial interventions (such as cognitive-behavioural therapy and pain-coping skills).
Here are the findings for those treatments most relevant in alternative medicine (it is interesting that most alternative medicines were not even considered because of lack of evidence and that the team of researchers can hardly be accused of an anti-alternative medicine bias, since its senior author has a track record of publishing results favourable to alternative medicine):
Current evidence shows significant positive effects in favour of exercise on pain, function, quality of life and work related outcomes in the short and long-term for all the musculoskeletal pain presentations (compared to no exercise or other control) but the evidence regarding optimal content or delivery of exercise in each case is inconclusive.
The evidence from a good quality individual patient data meta-analysis suggests that acupuncture may be effective for short-term relief of back pain and knee pain with medium summary effect sizes respectively compared with usual care or no acupuncture. However, effects on function were reported to be minimal and not maintained at longer-term follow-up. Similarly for neck and shoulder pain, acupuncture was only found to be effective for short-term (immediately post-treatment and at short-term follow-up) symptom relief compared to placebo.
Current evidence regarding manual therapy is beset by heterogeneity. Due to paucity of high quality evidence, it is uncertain whether the efficacy of manual therapy might be different for different patient subgroups or influenced by the type and experience of professional delivering the therapy. On the whole, the available evidence suggests that manual therapy may offer some beneficial effects on pain and function, but it may not be superior to other non-pharmacological treatments (e.g. exercise) for patients with acute or chronic musculoskeletal pain.
Overall. the authors concluded that the best available evidence shows that patients with musculoskeletal pain problems in primary care can be managed effectively with non-pharmacological treatments such as self-management advice, exercise therapy, and psychosocial interventions. Pharmacological interventions such as corticosteroid injections (for knee and shoulder pain) were shown to be effective treatment options for the short-term relief of musculoskeletal pain and may be used in addition to non-pharmacological treatments. NSAIDs and opioids also offer short-term benefit for musculoskeletal pain, but the potential for adverse effects must be considered. Furthermore, the optimal treatment intensity, methods of application, amount of clinical contact, and type of provider or setting, are unclear for most treatment options.
These findings confirm what we have pointed out many times before on this blog. There is very little that alternative therapies have to offer for musculoskeletal pain. Whenever it is possible, I would recommend exercise therapy initiated by a physiotherapist; it is inexpensive, safe, and at least as effective as acupuncture or chiropractic or osteopathy.
Practitioners of alternative medicine will, of course, not like this solution.
Acupuncturists may not be that bothered by such evidence: their focus is not necessarily on musculoskeletal but on a range of other conditions (with usually little evidence, I hasten to add).
But for chiropractors and osteopaths, this is much more serious, in my view. Of course, some of them also claim to be able to treat a plethora of non-musculoskeletal conditions (but there the evidence is even worse than for musculoskeletal pain, and therefore this type of practice is clearly unethical). And those who see themselves as musculoskeletal specialists have to either accept the evidence that shows little benefit and considerable risk of spinal manipulation, or go in a state of denial.
In the former case, the logical conclusion is to look for another job.
In the latter case, the only conclusion is that their practice is not ethical.
This is a fascinating new review of upper neck manipulation. It raises many concerns that we, on this blog, have been struggling with for years. I take the liberty of quoting a few passages which I feel are important and encourage everyone to study the report in full:
The Minister of Health, Seniors and Active Living gave direction to the Health Professions Advisory Council (“the Council”) to undertake a review related to high neck manipulation.
Specifically, the Minister directed the Council to undertake:
1) A review of the status of the reserved act in other Canadian jurisdictions,
2) A literature review related to the benefits to patients and risks to patient safety associated with the procedure, and
3) A jurisprudence review or a review into the legal issues that have arisen in Canada with respect to the performance of the procedure that touch upon the risk of harm to a patient.
In addition, the Minister requested the Council to seek written input on the issue from:
- Manitoba Chiropractic Stroke Survivors
- Manitoba Chiropractic Association
- College of Physiotherapists of Manitoba
- Manitoba Naturopathic Association
- College of Physicians and Surgeons of Manitoba
- other relevant interested parties as determined by the Council
… The review indicated that further research is required to:
- strengthen evidence for the efficacy of cervical spinal manipulations (CSM) as a treatment for neck pain and headache, “as well as for other indications where evidence currently does not exist (i.e., upper back and should/arm pain, high blood pressure, etc.)”
- establish safety and efficacy of CSM in infants and children
- assess the risk versus benefit in consideration of using HVLA cervical spine manipulation, which also involve cost-benefit analyses that compare CSM to other standard treatments.
… the performance of “high neck manipulation” or cervical spine manipulation does present a risk of harm to patients. This risk of harm must be understood by both the patient and the practitioner.
Both the jurisprudence review and the research literature review point to the need for the following actions to mitigate the risk of harm associated with the performance of cervical spine manipulation:
- Action One: Ensure that the patient provides written informed consent prior to initiating treatment which includes a discussion about the risk associated with cervical spine manipulation.
- Action Two: Provide patients with information to assist in the early recognition of a serious adverse event.
The British press recently reported that a retired bank manager (John Lawler, aged 80) died after visiting a chiropractor in York. This tragic case was published in multiple articles, most recently in THE SUN. Personally, I find this regrettable – not the fact that the press warns consumers of chiropractic, but the tone and content of the articles.
Let me explain this by citing the one in THE SUN of today. Here is the critical bit that concerns me:
Ezvard Ernst, Emeritus Professor of Complementary Medicine at Exeter University, published a study showing at least 26 people had died as a result. He said: “The evidence is not in favour of chiropractic treatments. Nobody knows how many have suffered severe complications or died.” Edvard Ernst, Professor of Complementary Medicine, says many have suffered complications or died from chiropractors treatments… A study from Exeter University shows at least 26 people have died as a result of treatment.
And what is wrong with this?
The answer is lots:
- My first name is consistently misspelled (a triviality, I agree).
- I am once named as Emeritus Professor and once as Professor of Complementary Medicine. The latter is wrong (another triviality, perhaps, but some of my more demented critics have regularly accused me of carrying wrong titles)
- The mention of 26 deaths after chiropractic treatments is problematic and arguably misleading (see below).
- Our ‘study’ was not a study but a systematic review (another triviality?).
Now you probably think I am being pedantic, but I feel that the article is regrettable not so much by what it says but by what it fails to say. To understand this better, I will below copy my emails to the journalist who asked for help in researching this article.
- My email of 17/10 answering all 7 of the journalist’s specific questions:
- 1. Why are you sceptical of chiropractic?
- I have researched the subject for more than 2 decades, and I know that the evidence is not in favour of chiropractic
- 2. How many people do you believe have died in Britain as a result of being treated by a chiropractor? If it’s not possible to say, can you estimate?
- nobody knows how many patients have suffered severe complications or deaths. there is no system to monitor such events that is comparable to the post-marketing surveillance of conventional medicine. we did some research and found that the under-reporting of cases of severe complications was close to 100% in the UK.
- 3. What is so dangerous about chiropractic? Is there a particular physical treatment than endangers life?
- manipulations that involve rotation and over-extension of the upper spine can lead to a vertebral artery breaking up. this causes a stroke which sometimes is fatal.
- 4. Is the industry well regulated?
- UK chiropractors are regulated by the General Chiropractic Council. it is debatable whether they are fit for purpose (see here:http://edzardernst.com/2015/02/the-uk-general-chiropractic-council-fit-for-purpose/)
- 5. Should we be suspicious of claims that chiropractic can cure things like IBS and autism?
- such claims are not based on good evidence and therefore misleading and unethical. sadly, however, they are prevalent.
- 6. Who trains chiropractors?
- there are numerous colleges that specialise in that activity.
- 7. Is it true Prince Charles is to blame for the rise in popularity/prominence of chiropractic?
- I am not sure. certainly he has been promoting all sorts of unproven treatments for decades.
- My email of 18/10 answering 3 further specific questions
- 1. Would you actively discourage anyone from being treated by a chiropractor?
yes, anyone I feel responsible for
2. Are older people particularly at risk or could one wrong move affect anyone?
older people are at higher risk of bone fractures and might also have more brittle arteries prone to dissection
3. If someone has, say, a bad back or stiff neck what treatment would you recommend instead of chiropractic?
I realise every case is different, but you are sceptical of all complementary treatments (as I understand it) so what would you suggest instead?
I would normally consider therapeutic exercises and recommend seeing a good physio.
- 3. My email of 23/10 replying to his request for specific UK cases
- the only thing I can offer is this 2001 paper
- where we discovered 35 cases seen by UK neurologists within the preceding year. the truly amazing finding here was that NONE of them had been reported anywhere before. this means under-reporting was exactly 100%.
END OF QUOTES
I think that makes it quite obvious that much relevant information never made it into the final article. I also know that several other experts provided even more information than I did which never appeared.
The most important issues, I think, are firstly the lack of a monitoring system for adverse events, secondly the level of under-reporting and thirdly the 50% rate of mild to moderate adverse-effects. Without making these issues amply clear, lay readers cannot possibly make any sense of the 26 deaths. More importantly, chiropractors will now be able to respond by claiming: 26 deaths compare very favourably with the millions of fatalities caused by conventional medicine. In the end, the message that will remain in the heads of many consumers is this: CONVENTIONAL MEDICINE IS MUCH MORE DANGEROUS THAN CHIROPRACTIC!!! (The 1st comment making this erroneous point has already been published: Don’t be stupid Andy. You wanna discuss how many deaths occur due to medication side effects and drug interactions? There is a reason chiros have the lowest malpractice rates.)
Don’t get me wrong, I am not accusing the author of the SUN-article. For all I know, he has filed a very thoughtful and complete piece. It might have been shortened by the editor who may also have been the one adding the picture of the US starlet with her silicone boobs. But I am accusing THE SUN of missing a chance to publish something that might have had the chance of being a meaningful contribution to public health.
Perhaps you still think this is all quite trivial. Yet, after having experienced this sort of thing dozens, if not hundreds of times, I disagree.
This is the question asked by the American Chiropractic Association. And this is their answer [the numbers in square brackets were inserted by me and refer to my comments below]:
Chiropractic is widely recognized  as one of the safest drug-free, non-invasive therapies available for the treatment of neuromusculoskeletal complaints . Although chiropractic has an excellent safety record , no health treatment is completely free of potential adverse effects. The risks associated with chiropractic, however, are very small . Many patients feel immediate relief following chiropractic treatment , but some may experience mild soreness, stiffness or aching, just as they do after some forms of exercise . Current research shows that minor discomfort or soreness following spinal manipulation typically fades within 24 hours …
Some reports have associated high-velocity upper neck manipulation with a certain rare kind of stroke, or vertebral artery dissection . However, evidence suggests that this type of arterial injury often takes place spontaneously in patients who have pre-existing arterial disease . These dissections have been associated with everyday activities such as turning the head while driving, swimming, or having a shampoo in a hair salon . Patients with this condition may experience neck pain and headache that leads them to seek professional care—often at the office of a doctor of chiropractic or family physician—but that care is not the cause of the injury. The best evidence indicates that the incidence of artery injuries associated with high-velocity upper neck manipulation is extremely rare—about one to three cases in 100,000 patients who get treated with a course of care . This is similar to the incidence of this type of stroke among the general population …
When discussing the risks of any health care procedure, it is important to look at that risk in comparison to other treatments available for the same condition . In this regard, the risks of serious complications from spinal manipulation for conditions such as neck pain and headache compare very favorably with even the most conservative care options. For example, the risks associated with some of the most common treatments for musculoskeletal pain—over-the-counter or prescription nonsteroidal anti-inflammatory drugs (NSAIDS) and prescription painkillers—are significantly greater than those of chiropractic manipulation …
Doctors of chiropractic are well trained professionals who provide patients with safe, effective care for a variety of common conditions. Their extensive education has prepared them to identify patients who have special risk factors  and to get those patients the most appropriate care, even if that requires referral to a medical specialist .

- The difference between different treatments is not merely their safety but also their effectiveness; in the end it is the risk/benefit balance that determines their value.
- Not true, there are no good predictors to identify at-risk populations.
- Chiropractors are notoriously bad at referring to other healthcare professionals; they have a huge conflict of interest in keeping up their cash-flow.
So, is chiropractic a safe treatment?
My advice here is not to ask chiropractors but independent experts.
The European Academies Science Advisory Council (EASAC) is an umbrella organization representing 29 national and international scientific academies in Europe, including the Royal Society (UK) and Royal Swedish Academy of Sciences. One of its aims is to influence policy and regulations across the European Union. Now, the EASAC has issued an important and long-awaited verdict on homeopathy:
The EASAC is publishing this Statement to build on recent work by its member academies to reinforce criticism of the health and scientific claims made for homeopathic products. The analysis and conclusions are based on the excellent science-based assessments already published by authoritative and impartial bodies. The fundamental importance of allowing and supporting consumer choice requires that consumers and patients are supplied with evidence-based, accurate and clear information. It is, therefore, essential to implement a standardised, knowledge-based regulatory framework to cover product efficacy, safety and quality, and accurate advertising practices, across the European Union (EU). Our Statement examines the following issues:
- Scientific mechanisms of action—where we conclude that the claims for homeopathy are implausible and inconsistent with established scientific concepts.
- Clinical efficacy—we acknowledge that a placebo effect may appear in individual patients but we agree with previous extensive evaluations concluding that there are no known diseases for which there is robust, reproducible evidence that homeopathy is effective beyond the placebo effect.
There are related concerns for patient-informed consent and for safety, the latter associated with poor quality control in preparing homeopathic remedies. Promotion of homeopathy—we note that this may pose significant harm to the patient if incurring delay in seeking evidence-based medical care and that there is a more general risk of undermining public confidence in the nature and value of scientific evidence. Veterinary practice—we conclude similarly that there is no rigorous evidence to
substantiate the use of homeopathy in veterinary medicine and it is particularly worrying when such products are used in preference to evidence-based medicinal products to treat livestock infections. We make the following recommendations.
1. There should be consistent regulatory requirements to demonstrate efficacy, safety and quality of all products for human and veterinary medicine, to be based on verifiable and objective evidence, commensurate with the nature of the claims being made. In the absence of this evidence, a product should be neither approvable nor registrable by national regulatory agencies for the designation medicinal product.
2. Evidence-based public health systems should not reimburse homeopathic products and practices unless they are demonstrated to be efficacious and safe by rigorous testing.
3. The composition of homeopathic remedies should be labelled in a similar way to other health products available: that is, there should be an accurate, clear and simple description of the ingredients and their amounts present in the formulation.
4. Advertising and marketing of homeopathic products and services must conform to established standards of accuracy and clarity. Promotional claims for efficacy, safety and quality should not be made without demonstrable and reproducible evidence.
