The ‘Dr Rath Foundation’ just published a truly wonderful (full of wonders) article about me. I want to publicly congratulate the author: he got my name right [but sadly not much more]. Here is the opening passage of the article which I encourage everyone to read in full [the numbers in square brackets refer to my comments below].

Professor Edzard Ernst: A Career Built On Discrediting Natural Health Science? [1]

Professor Edzard Ernst, a retired German [2] physician and academic, has recently [3] become a prominent advocate of plans that could potentially outlaw [4] the entire profession of naturopathic doctors [5] in Germany. Promoting the nonsensical idea that naturopathic medicine somehow poses a risk to public health, Ernst attacks its practitioners as supposedly having been educated in “nonsense” [6]. Tellingly, however, given that he himself has seemingly not published even so much as one completely original scientific trial of his own [7], Ernst’s apparent attempts to discredit natural healthcare approaches are largely reliant instead on his analysis or review of handpicked negative studies carried out by others [8].

  1. When I was appointed at Exeter to research alternative medicine in 1993, I had already been a full professor at Hannover, Germany and subsequently at Vienna, Austria. If anything, coming to Exeter was a big step down in terms of ‘career’, salary, number of co-workers etc. (full details in my memoir)
  2. I am German-born, became an Austrian citizen in 1990, and since 2000 I am a British national.
  3. I have been critical about the German ‘Heilpraktiker’ for more than 20 years.
  4. This refers to the recent ‘Muensteraner Memorandum’ which is the work of an entire team of multidisciplinary experts and advocates reforming this profession.
  5. ‘Heilpraktiker’ are certainly not doctors; they have no academic or medical background.
  6. This is correct, and I stand by my statement that educating people in vitalism and other long-obsolete concepts is pure nonsense.
  7. Since I am researching alternative medicine, I have conducted and published about 40 ‘scientific trials’, and before that time (1993) I have published about the same number again in various other fields.
  8. This refers to systematic reviews which, by definition, include all the studies available on a defines research question, regardless of their conclusion (their aim is to minimise random and selection biases)  .

I hope you agree that these are a lot of mistakes (or are these even lies?) in just a short paragraph.

Now you probably ask: who is Dr Rath?

Many reader of this blog will have heard of him. This is what the Guardian had to say about this man:

Matthias Rath, the vitamin campaigner accused of endangering thousands of lives in South Africa by promoting his pills while denouncing conventional medicines as toxic and dangerous, has dropped a year-long libel action against the Guardian and been ordered to pay costs.

A qualified doctor who is thought to have made millions selling nutritional supplements around the globe through his website empire, Rath claimed his pills could reverse the course of Aids and distributed them free in South Africa, where campaigners, who have won a hard-fought battle to persuade the government to roll out free Aids drugs to keep millions alive, believe Rath’s activities led to deaths.

The Dr Rath Foundation focuses its promotional activities on eight countries – the US, the UK, Germany, the Netherlands, South Africa, Spain, France and Russia – claiming that his micronutrient products will cure not just Aids, but cancer, heart disease, strokes and other illnesses…

I am sure you now understand why I am rather proud of being defamed by this source!

 

 

The nonsense that some naturopaths try to tell the public never ceases to amaze me. This article is a good example: a “naturopathic doctor” told a newspaper that “We do have a reputation associated with cancer, but we don’t treat cancer. We use highly intelligent computer software to find out what is wrong with the body at a scientific level, and we simply correct that, and the people who do that, they cure their own cancer.” As far as he is concerned, “The only hope for cancer is alternative medicine… When you look at the medical texts, the scientific literature, what is used, the chemotherapy and the radiation, they cannot cure cancer,” he said.

Through artificial intelligence, he said that he simply teaches people how to heal. Clients are hooked up to a computer that reads their body and gives a printout of what needs to be done to correct the abnormalities. “It looks at the abnormalities in the energetic pathways, abnormalities in nutritional status, and abnormalities in the toxic load of the body and how much it can carry. Once these things are identified and you actually put the patient on a path, they go out and heal themselves. I have nothing to do with it,” he said.

Before you discard this neuropath as an unimportant nutter, consider that this article is a mere example. There are thousands more.

This website, for instance, gives the impression of being much more official and trustworthy by adopting the name of CANCER TREATMENT CENTERS OF AMERICA. But the claims are just as irresponsible:

… natural therapies our naturopathic medicine team may recommend include:

  • Herbal and botanical preparations, such as herbal extracts and teas
  • Dietary supplements, such as vitamins, minerals and amino acids
  • Homeopathic remedies, such as extremely low doses of plant extracts and minerals
  • Physical therapy and exercise therapy, including massage and other gentle techniques used on deep muscles and joints for therapeutic purposes
  • Hydrotherapy, which prescribes water-based approaches like hot and cold wraps, and other therapies
  • Lifestyle counseling, such as exercise, sleep strategies, stress reduction techniques, as well as foods and nutritional supplements
  • Acupuncture, to help with side effects like nausea and vomiting, dry mouth, hot flashes and insomnia
  • Chiropractic care, which may include hands-on adjustment, massage, stretching, electronic muscle stimulation, traction, heat, ice and other techniques.

Vis a vis this plethora of irresponsible and dangerous promotion of quackery by naturopathic charlatans, I feel angry, sad and powerless. I know that my efforts to prevent cancer patients going to an early grave because of such despicable actions are bound to be of very limited success. But that does not mean that I will stop trying to tell the truth:

THERE IS NOT A JOT OF EVIDENCE THAT NATUROPATHY CAN CURE CANCER. SO, PLEASE DO NOT GO DOWN THIS ROUTE!

PS: …and no, I am not paid by BIG PHARMA or anyone else to say so.

 

 

According to its authors, the objective of this paper was “to demonstrate the need for using both alternative and conventional treatments to improve clinical outcomes in the treatment of schizoaffective disorder”.

Instead of doing anything remotely like this, the authors present two case histories:

  • a 23-y-old female (case 1)
  • and a 34-y-old female (case 2).

Both patients had been diagnosed with schizoaffective disorder of the bipolar type. Individualized homeopathic treatment was initiated for both patients, who were also on conventional medications. A Likert scale was used to evaluate the intensity of each patient’s symptoms at each follow-up, based on self-reporting.

During the course of treatment, both patients’ symptoms normalized, and they regained their ability to hold jobs, attend school (at the age of 23/34 ???), and maintain healthy relationships with their families and partners while requiring fewer pharmaceutical interventions.

The authors concluded that these two cases …  illustrate the value of individualized homeopathic prescriptions with proper case management in the successful treatment of that disorder. Future large-scale, double-blind, placebo-controlled studies should investigate individualized homeopathic treatments for mental health concerns, because the diseases cause great economic and social burden.

The article was published in Altern Ther Health Med.by Grise DE, Peyman T, and Langland J who seem to be from the ‘Southwest College of Naturopathic Medicine, Tempe, Arizona’. Two of the authors have recently published similarly odd case reports:

  1. This case report demonstrates a successful approach to managing patients with type 2 diabetes mellitus (DM2). Botanical herbs (including Gymnema sylvestre) and nutrients (including alpha lipoic acid and chromium) were used alongside metformin to help improve insulin sensitization; however, the greatest emphasis of treatment for this patient centered on a low-carbohydrate, whole-foods diet and regular exercise that shifted the focus to the patient’s role in controlling their disease. Research on DM2 often focuses on improving drug efficacy while diet and lifestyle are generally overlooked as both a preventive and curative tool. During the 7 months of treatment, the patient’s hemoglobin A1c and fasting glucose significantly decreased to within normal ranges and both cholesterol and liver enzyme markers normalized. A significant body of evidence already exists advocating for disease management using various diets, including Mediterranean, low-carb, and low-fat vegan diets; however, no clear dietary standards have been established. This study supports the use of naturopathic medicine as well as dietary and lifestyle changes to develop the most efficacious approach for the treatment of DM2.
  2. This case report illustrates the improvement of an acupuncture-treated patient who incurred a severe traumatic brain injury (TBI) from a snowboarding accident. Over 4 years, the patient progressed from initially not being able to walk, having difficulty with speech, and suffering from poor eyesight to where he has now regained significant motor function, speech, and vision and has returned to snowboarding. A core acupuncture protocol plus specific points added to address the patient’s ongoing concerns was used. This case adds to the medical literature by demonstrating the potential role of acupuncture in TBI treatment.
  3. The current case study intended to evaluate the benefits of an alternative, multifaceted approach-including botanical and homeopathic therapies in conjunction with a low-FODMAP diet-in the treatment of small intestinal bacterial overgrowth (SIBO) and its associated symptoms. Design • The research team performed a case study. Setting • The study was conducted at SCNM Medical Center (Tempe, AZ, USA). Participant • The participant was a female patient at the SCNM Medical Center with chronic, daily, severe abdominal bloating and pain that particularly worsened after meals and by the end of the day. The patient also had a significant history of chronic constipation that had begun approximately 10 y prior to her experiencing the daily abdominal pain. Intervention • Based on a lactulose breath test for hydrogen and methane, the research team diagnosed the patient with a case of mild SIBO. The treatment approach was multifaceted, involving a low-FODMAP diet, antimicrobial botanical therapy, and homeopathic medicine. Results • The patient’s abdominal pain and bloating resolved with the treatment of the SIBO, although her underlying constipation, which was likely associated with other factors, remained. Conclusions • This case study supports an alternative, multifaceted approach to the treatment of SIBO and commonly associated symptoms.
  4. The study intended to examine the benefits of treating plantar warts with a topical, botanical blend that has had clinical success treating herpes simplex virus cold sores. Methods • A synergistic botanical blend was applied topically. Setting • The case report was completed at the Southwest College of Naturopathic Medicine (Tempe, Arizona, USA). Participant • The participant was a 24-y-old male soccer player, 177.8 cm tall, and weighing 69 kg with previously diagnosed, viral mosaic warts. Intervention • The patient used a pumice stone during bathing for the first week to remove dead tissue and ensure sufficient contact and entry of the botanical gel into infected tissue. After drying the area, the patient applied the botanical gel blend 1 to 2 times daily postshower, spreading it evenly across the surface of the entire lesion. The patient discontinued the exfoliation technique after the first week. Results • Within the first week of treatment, the patient noted changes to the infected area of the hallux epidermal tissue. The combination of exfoliation and application of the gel caused marked, visible differences in presentation by the fifth day of treatment. At 1-mo postintervention, or day 90, the epidermal tissue was asymptomatic and devoid of petechiae, malformations, or visible infection. Conclusions • The results of the current case study directly contrast with the drawbacks of commonly accepted, first-line interventions in the treatment of viral plantar warts and, in many respects, demonstrate better efficacy and fewer side effects than the standard of care. The positive results also highlight the necessity for additional study in the fields of sports medicine and podiatry to further establish the botanical blend when treating viral plantar in athletes, an overall at-risk population for the condition.
  5. This study intended to examine the benefits of treatment of a pediatric patient with natural supplements and an elimination diet for IgG food allergies. Design • The research team reported a case study. Setting • The study was conducted at Southwest Naturopathic Medical Center (Tempe, AZ, USA). Participant • The participant was a 10-y-old Caucasian female who had diagnoses of allergic rhinitis and reactive bronchospasm, the second of which was exacerbated by allergens such as wheat, perfumes, and seasonal flora. Intervention • Following testing for IgE- and IgG-reactive foods, the patient was treated with natural supplements to reduce her allergic responses and was instructed to make dietary changes to eliminate the IgG-reactive foods. Outcome Measures • The patient’s symptom severity was tracked starting 1 mo after her initial visit to Southwest Naturopathic Medical Center. The severity was based on the patient’s subjective reports about her congestion to her mother and on her mother’s observations of the effect of symptoms on her attention and school performance. The bronchospasm severity was based on the frequency of a sensation of wheezing and chest tightness, the frequency of inhaler use, and the occurrence of any exacerbation of symptoms with acute respiratory illness Results • After 1 mo, in which the patient used the natural supplements, she experienced a 90% improvement in coughing; a 70% improvement in nasal congestion; less chest tightness; and no need for use of loratadine, diphenhydramine, or albuterol. At the 8-mo follow-up visit, her nasal congestion was reported to be entirely gone. Conclusions • The case demonstrates the effectiveness of natural supplements and a diet eliminating IgG-reactive foods in the treatment and management of pediatric allergic rhinitis and reactive bronchospasm.

These articles are all quite similarly ridiculous, but the first one reporting two patients who felt better after taking individualised homeopathic remedies (together with conventional medicines) is, I think, the ‘best’. I suggest the authors continue their high-flying careers by publishing a series of further case reports on similar themes:

  • How the crowing of the cock in the morning causes the sun to rise.
  • The danger of WW 3 causes Americans to elect an idiot as president.
  • Increase of CO2 emissions due to global warming.
  • Immunisation neglect caused by measles outbreaks.
  • Brexit vote due to economic downturn.
  • Excessive alcohol consumption caused by hangover.
  • Why does lying in bed cause tiredness?

Please feel free to suggest more ‘post hoc propter hoc’ research themes for our aspiring team of naturopathic pseudo-scientists to be published in Altern Ther Health Med.

 

 

 

Orac recently lost his rag over JOHN WEEKS, editor of JCAM (see also here, here, here and here), and was less than appreciative of his recent comments on the Samueli-donation. Personally, I think that this was a bit harsh. To compensate the poor chap for such an injustice, I herewith offer John a place in my ‘Alt Med Hall of Fame’.

There he is in good company:

Deepak Chopra (US entrepreneur)

Cheryl Hawk (US chiropractor)

David Peters (osteopathy, homeopathy, UK)

Nicola Robinson (TCM, UK)

Peter Fisher (homeopathy, UK)

Simon Mills (herbal medicine, UK)

Gustav Dobos (various, Germany)

Claudia Witt (homeopathy, Germany and Switzerland)

George Lewith (acupuncture, UK)

John Licciardone (osteopathy, US)

have all been honoured in the same way.

But John is special!

I have mentioned him several times before (see here, here and here); what makes him special, in my view, is that he is such a shining example of an expert in ‘integrative medicine’. He calls himself a “a writer, speaker, chronicler and organizer whose work in the movement for integrative health” and proudly presents his lifetime achievement award (I urge you to read it – everyone who is anyone in the US quackery-cult pored a little praise over John – but be careful, you might feel acutely nauseous). Towards the end of this document, John adds some self-praise by summarising the many other ‘HONORS’ he has received:

  • – For public education, American Association of Naturopathic Physicians (1988)
  • – For role in historic regional accreditation of a college of natural health sciences, Bastyr College/now Bastyr University (1989)
  • – Commencement speaker, Bastyr College (1989)
  • – Honorary Doctor of Naturopathic Medicine, Bastyr University (1992)
  • – For service, American Association of Naturopathic Physicians (1993)
  • – For service, Washington Mental Health Counselors Association (1995)
  • – Commencement speaker, Northwestern Health Sciences University (2010)
  • – Honorary Doctor of Laws, National University of Health Sciences (2011)
  • – Honorary Doctor of Naturopathic Medicine, Canadian College of Naturopathic Medicine (2012)
  • – Commencement speaker, New York Chiropractic College (2013)
  • – Champion of Naturopathic Medicine, American Association of Naturopathic Physicians (2013)

So what? I hear you say, what is so special about that?

I will tell you what is special:

  • John is not a doctor,
  • John is not a practitioner,
  • John is not a scientist,
  • John has not published anything that we might call research,
  • John has not studied any healthcare-related subject,
  • John has, as far as I can see, no real university degree at all.

I find this remarkable and wonderful! It shows us like few other things what to think of the alternative medicine-cult. Not only can truly anyone become president in the US (as the last election has demonstrated); in the US anyone can become a celebrated and honoured champion of alternative medicine as well!

Welcome in my ‘Hall of Fame’ John!

We all know Epsom salt, don’t we? This paper provides an interesting history of it: The purgative effect of the waters of Epsom, in southern England, was first discovered in the early seventeenth century. Epsom subsequently developed as one of the great English spas where high society flocked to take the medicinal waters. The extraction of the Epsom Salts from the spa waters and their chemical analysis, the essential feature of which was magnesium sulphate, were first successfully carried out by Doctor Nehemiah Grew, distinguished as a physician, botanist and an early Fellow of the Royal Society. His attempt to patent the production and sale of the Epsom Salts precipitated a dispute with two unscrupulous apothecaries, the Moult brothers. This controversy must be set against the backcloth of the long-standing struggle over the monopoly of dispensing of medicines between the Royal College of Physicians and the Worshipful Society of Apothecaries of London.

Epsom salt has the reputation of being very safe. But unfortunately, even something as seemingly harmless as Epsom salt can become dangerous in the hand of people who have little understanding of physiology and medicine. Indian doctors have just published a paper in (‘BMJ Case Reports’) with the details of a 38-year-old non-alcoholic, non-diabetic man suffering from gallstones. The patient was prescribed three tablespoons of Epsom salt to be taken with lukewarm water for 15 days for ‘stone dissolution’ by a ‘naturopathy practitioner’. He subsequently developed loss of appetite and darkening of urine from the 12th day of treatment and jaundice from the second day after treatment completion. The patient denied fevers, skin rash, joint pains, myalgia, abdominal pain, abdominal distension and cholestatic symptoms.

Examination revealed a deeply icteric patient oriented to time, place and person without an enlarged liver or stigmata of chronic liver disease. Liver function tests were abnormal, and a  liver biopsy revealed sub-massive necrosis with dense portal-based fibrosis, mixed portal inflammation, extensive peri-venular canalicular and hepatocellular cholestasis with macro-vesicular steatosis and peri-sinusoidal fibrosis (suggestive of steato-hepatitis) without evidence of granulomas, inclusion bodies or vascular changes suggestive of acute drug-induced liver injury.

After discontinuation of Epsom salt and adequate hydration, the patient had an uneventful recovery with normalisation of liver function tests after 38 days.  The Roussel Uclaf Causality Assessment score was strongly suggestive of Epsom salt-induced liver injury.

I was invited to provide a comment and stated that, in my view, this case reminds us:

1) that naturopaths prescribe a lot of nonsense,

2) that not everything which is promoted as natural is safe,

3) that treatments which apparently have ‘stood the test of time’ can still be rubbish, and

4) that even a relatively harmless remedy can become life-threatening, if one takes it at a high dose for a prolonged period of time.

Naturopaths have advocated Epsom salt for gall-bladder problems since centuries, yet there is no good evidence that it works. It is time that alternative practitioners abide by the rules of evidence-based medicine.

A quick Medline search reveals that there is only one further report of a serious adverse effect after Epsom salt intake: a case of fatal hypermagnesemia caused by an Epsom salt enema. A 7-year-old male presented with cardiac arrest and was found to have a serum magnesium level of 41.2 mg/dL (33.9 mEq/L) after having received an Epsom salt enema earlier that day. The medical history of Epsom salt, the common causes and symptoms of hypermagnesemia, and the treatment of hypermagnesemia are reviewed. The easy availability of magnesium, the subtle initial symptoms of hypermagnesemia, and the need for education about the toxicity of magnesium should be of interest to physicians.

… and to alternative practitioners, I hasten to add.

We have repeatedly discussed on this blog the fact that many alternative practitioners are advising their patients against vaccinations, e. g.:

There is little doubt that this phenomenon contributes to low immunisation rates. This, in turn, is a contributing factor to outbreaks of measles and other infectious diseases. The website of the European Centre for Disease Prevention and Control has recently published data on measles outbreaks in Europe:

Bulgaria: There is an increase by three cases since 21 July 2017. Since the beginning of 2017 and as of 16 July, Bulgaria reported 166 cases. During the same time period in 2016 Bulgaria reported one case.

France: On 27 July 2017 media quoting the French Minister of Health reported the death of a 16-year-old unvaccinated girl. She had fallen sick in Nice and died on 27 June 2017 in Marseille.

Germany: There is an increase by four cases since the last report on 21 July 2017. Since the beginning of 2017 and as of 26 July, Germany reported 801 cases. During the same time period in 2016 Germany reported 187 cases.

Italy: There is an increase by 170 cases since 21 July 2017. Since the beginning of 2017 and as of 25 July, Italy reported 3 842 cases, including three deaths. Among the cases, 271 are healthcare workers. The median age is 27 years, 89% of the cases were not vaccinated and 6% received only one dose of vaccine.

Romania: There is an increase by 229 cases, including one additional death, since 21 July 2017. Since 1 January 2016 and as of 21 July 2017, Romania reported 8 246 cases, including 32 deaths. Cases are either laboratory-confirmed or have an epidemiological link to a laboratory-confirmed case. Infants and young children are the most affected groups. Timis, in the western part of the country closest to the border with Serbia, is the most affected district with 1 215 cases. Vaccination activities are ongoing in order to cover communities with suboptimal vaccination coverage.

Spain: There is an increase by seven cases since 14 July 2017. Since the beginning of 2017 and as of 25 July, Spain reported 145  measles cases.

United Kingdom: Public Health Wales reported two additional cases related to the outbreak in Newport and Torfaen, bringing the total to ten cases related to this outbreak. In England and Wales there is an increase by 76 cases since 21 July 2017. Since the beginning of 2017 and as of 23 July 2017, England and Wales reported 922 cases. In the same time period in 2016, they reported 946 cases.

In addition to the updates listed above ECDC produces a monthly measles and rubella monitoring report with surveillance data provided by the member states through TESSy. The last report was published on 11 July 2017 with data up to 31 May 2017.

Measles outbreaks continue to occur in EU/EEA countries. There is a risk of spread and sustained transmission in areas with susceptible populations. The national vaccination coverage remains less than 95% for the second dose of MMR in the majority of EU/EEA countries. The progress towards elimination of measles in the WHO European Region is assessed by the European Regional Verification Commission for Measles and Rubella Elimination (RVC). Member States of the WHO European Region are making steady progress towards the elimination of measles. At the fifth meeting of the RVC for Measles and Rubella in October 2016, of 53 countries in the WHO European Region, 24 (15 of which are in the EU/EEA) were declared to have reached the elimination goal for measles, and 13 countries (nine in the EU/EEA) were deemed to have interrupted endemic transmission for between 12 and 36 months, meaning they are on their way to achieving the elimination goal. However, six EU/EEA countries were judged to still have endemic transmission: Belgium, France, Germany, Italy, Poland and Romania. More information on strain sequences would allow further insight into the epidemiological investigation.

All EU/EEA countries report measles cases on a monthly basis to ECDC and these data are published every month. Since 10 March 2017, ECDC has been reporting measles outbreaks in Europe on a weekly basis and monitoring worldwide outbreaks on a monthly basis through epidemic intelligence activities. ECDC published a rapid risk assessment on 6 March.

Personally, I believe that it is high time to stop the rhetoric and actions of the anti-vaccination movements. This includes educating alternative practitioners and their patients. If necessary, we need regulation that prohibits their dangerous and unethical activities.

Traditional and folk remedies have been repeatedly been reported to contain toxic amounts of lead. I discussed this problem before; see here, here, and here. Recently, two further papers were published which are relevant in this context.

In the first article, Indian researchers presented a large series of patients with lead poisoning due to intake of Ayurvedic medicines, all of whom presented with unexplained abdominal pain.

In a retrospective, observational case series from a tertiary care center in India, the charts of patients who underwent blood lead level (BLL) testing as a part of workup for unexplained abdominal pain between 2005 and 2013 were reviewed. The patients with lead intoxication (BLLs >25 μg/dl) were identified and demographics, history, possible risk factors, clinical presentation and investigations were reviewed. Treatment details, duration, time to symptomatic recovery, laboratory follow-up and adverse events during therapy were recorded.

BLLs were tested in 786 patients with unexplained abdominal pain, and high levels were identified in 75 (9.5%) patients of which a majority (73 patients, 9.3%) had history of Ayurvedic medication intake and only two had occupational exposure. Five randomly chosen Ayurvedic medications were analyzed and lead levels were impermissibly high (14-34,950 ppm) in all of them. Besides pain in abdomen, other presenting complaints were constipation, hypertension, neurological symptoms and acute kidney injury. Anemia and abnormal liver biochemical tests were observed in all the 73 patients. Discontinuing the Ayurvedic medicines and chelation with d-penicillamine led to improvement in symptoms and reduction in BLLs in all patients within 3-4 months.

The authors of this paper concluded that the patients presenting with severe recurrent abdominal pain, anemia and history of use of Ayurvedic medicines should be evaluated for lead toxicity. Early diagnosis in such cases can prevent unnecessary investigations and interventions, and permits early commencement of the treatment.

The second article German researchers analysed 20 such ‘natural health products’ (NHPs) from patients with intoxication symptoms. Their findings revealed alarming high concentrations of mercury and/or lead (the first one in “therapeutic” doses). 82 % of the studied NHPs contained lead concentrations above the EU limit for dietary supplements. 62 % of the samples exceeded the limit values for mercury. Elevated blood lead and mercury levels in patients along with clinical intoxication symptoms corroborate the causal assumption of intoxication (s).

The authors concluded that, for NHPs there is evidence on a distinct toxicological risk with alarming low awareness for a possible intoxication which prevents potentially life-saving diagnostic steps in affected cases. In many cases patients do not communicate the events to their physicians or the local health authority so that case reports (e.g. the BfR-DocCentre) are missing. Thus, there is an urgent need to raise awareness and to initiate more suitable monitory systems (e.g. National Monitoring of Poisonings) and control practice protecting the public.

The authors of the 2nd paper also reported a detailed case report:

Patient, male, 31 with BMI slightly below normal, non-smoker, was referred to the neurological department of the university clinic with severe peripheral poly neuropathy and sensory motor symptoms with neuropathic pain. The patient was in good general state of health until approximately 3 weeks before hospital admission; he spent his holiday in Himalaya region and came back with headaches and fatigue. He was taking pain medication without any relieve; his routine blood values were normal. He claimed to take no further medications. Since poly neuropathy and fatigue could be caused by pesticides or other poisoning, i.e. heavy metals, we have been consulted for taking a detailed exposure history. While in the clinic, 3 different NHPs were found in form of globules, (a, b, c for morning, lunch time and evening respectively), which he imported from his trip to Asia and ingested 3 times a day against stress. We have analyzed these 3 NHPs and found: 45 μg/g, 53,000 μg/g and 28 μg/g lead (for morning, midday and evening globules, respectively) and additionally 15.72 μg/g mercury in the “evening globules”. Since, his blood metal levels were: 340 μg/L Pb and 15 μg/L Hg a diagnosis of heavy metal intoxication was made. Slowly occurring clinical recovery after starting chelation therapy corroborated with the causal assumption proposed. He was released for further consultancy to his family physician. The administrated treatment and the improvement of his status corroborate lead and mercury intoxication.

The researchers finish their paper with this stark warning: In many countries, even in Germany, no comprehensive nutria vigilance- or poisoning monitoring system exists, from which the application of natural health products and the consequent intoxication can be estimated. There is also an urgent need for comprehensive scientifically evaluated studies based on efficient national monitoring to protect the consumer from heavy metal intoxications. There are no comparable surveillance systems like the US ABLES program for lead- and no surveillance systems for mercury exposures allowing any comparisons. Exposure to lead and mercury from environmental sources remains an overlooked and serious public health risk.

A new joint position statement of the Italian Society of Diabetology (SID) and of the Italian Society for the Study of Arteriosclerosis (SISA) has recently been published. In the context of this blog, it seems relevant enough for its summary to be reproduced here:

Evidence showed that LDL-cholesterol lowering is associated with a significant cardiovascular risk reduction. The initial therapeutic approach to hypercholesterolaemia includes dietary modifications but the compliance to recommendations is often inadequate. Some dietary components with potential cholesterol-lowering activity are present in small amounts in food. Therefore, in recent years the use of “nutraceuticals” (i.e., nutrients and/or bioactive compounds with potential beneficial effects on human health) has become widespread. Such substances may be added to foods and beverages, or taken as dietary supplements (liquid preparations, tablets, capsules). In the present manuscript, the cholesterol-lowering activity of some nutraceuticals (i.e. fiber, phytosterols, soy, policosanol, red yeast rice and berberine) will be discussed along with: 1) the level of evidence on the cholesterol-lowering efficacy emerging from clinical trial; 2) the possible side effects associated with their use; 3) the categories of patients who could benefit from their use.

DATA SYNTHESIS:

Based on the current literature, the cholesterol-lowering effect of fiber, phytosterols and red yeast rice is consistent and supported by a good level of evidence. Over berberine, there is sufficient evidence showing significant cholesterol-lowering effects, although the results come from studies carried out almost exclusively in Asian populations. Data on the effects of soy are conflicting and, therefore, the strength of recommendation is quite low. The evidence on policosanol is inconclusive.

CONCLUSION:

Although health benefits may arise from the use of nutraceuticals with cholesterol-lowering activity, their use might be also associated with possible risks and pitfalls, some of which are common to all nutraceuticals whereas others are related to specific nutraceuticals.

Many advocates of alternative medicine are highly sceptical of the value of statins. Yet, it seems clear that statins exert considerably larger effects on our lipid profile than nutraceuticals. So, why not use the treatment that is best documented and most efficacious? One answer could lie in the well-known adverse effects of statins. However, can we be sure that nutraceuticals are devoid of serious side-effects? I am not sure that we can: statins have been fully investigated, and we therefore are well-informed about their risks. Nutraceuticals, by contrast, have not been monitored in such detail, and their safety profile is therefore not as well-understood.

Other advocates of alternative medicine argue that cholesterol (I use the term simplistically without differentiating between the ‘good and bad’ cholesterol) has been hyped by the pharmaceutical industry and is, in truth, not nearly as important a risk factor as we have been led to believe. This line of thought would consequently deny the need to lower elevated cholesterol levels and therefore negate the need for cholesterol-lowering treatments. This stance may be popular, particularly in the realm of alternative medicine, but, to the best of my knowledge, it is erroneous.

Obviously, the first line treatment for people with pathological lipid profiles is the adoption of different life-styles, particularly in terms of nutrition. This may well incorporate some of the nutraceuticals mentioned above. If that strategy is unsuccessful in normalizing our blood lipids – and it often is – we should consider the more effective conventional medications; and that unquestionably includes statins.

I do not expect that everyone reading these lines will agree with me, yet, after studying the evidence, this is my honest conclusion – and NO, I am not paid or otherwise rewarded by the pharmaceutical industry or anyone else!

 

The Committees of Advertising Practice (CAP) write and maintain the UK Advertising Codes, which are administered by the Advertising Standards Authority. On their website, the CAP recently published an updated advertising code for naturopathy. As we have regularly discussed the fact that the public is being frequently misled in this area, I consider the code important in the context of this blog. I therefore take the liberty of repeating it here – not least in the hope that this helps preventing misinformation in the future [the numbers in square brackets refer to me footnotes below].

START OF QUOTE

What is Naturopathy?

Naturopathy is a holistic [1] approach to healthcare that uses a combination of one or more different disciplines (for example herbal medicine or hydrotherapy) and a healthy lifestyle [2] in order to gain and maintain a healthy body [3].

What claims are likely to be acceptable?

The promotion of a healthy [4] lifestyle is likely to acceptable as are claims that go no further than those commonly accepted for healthy [4] eating, sleeping well, taking exercise and the like.

What claims are likely to be problematic?

The ASA and CAP have not yet been provided with evidence which demonstrates that Naturopathy can be used to treat medical conditions (Rule 12.1).  Therefore, any claims that go beyond accepted claims for a healthy [4] lifestyle are likely to be problematic [5] unless they are supported by a robust body of evidence.  In 2013, the ASA ruled against claims on a marketer’s website which said that Naturopathy could be used to treat acute and chronic illness and disease because the marketer had not provided any evidence in support of their claims (CNM The College of Naturopathic Medicine Ltd, 13 March 2013).

What about serious medical conditions?

Claims to offer treatment on conditions for which medical supervision should be sought [6] are likely to be considered to discourage essential treatment unless that treatment is carried out under the supervision of a suitably qualified health professional (Rule 12.2).

END OF QUOTE

Naturopathy has been the subject of my posts before – see for instance here, here, here, here and here. Naturopathy can be dangerous to the point where it can kill the patient – see for instance here and here. Therefore it is important that advertising gets regulated. To make it very clear: the above statement by the CAP is, in my view, a step in the right direction, and I encourage alternative practitioners to look up the equivalent CAP documents for their specific therapy.

Having said that, I still feel the need to make a few comments:

  1. It is misleading to call naturopathy ‘holistic’. This is often factually incorrect and also gives the impression that conventional medicine is not holistic – see also here.
  2. Are we sure that all lifestyles promoted by naturopaths are, in fact, healthy?
  3. Maintaining a healthy body is naturopathy speak for DISEASE PREVENTION. Who decides what is effective prevention? On what evidence? How come many naturopaths are against the most effective means of prevention of all times – vaccination?
  4. Who decides what is ‘healthy’? On what evidence?
  5. Why ‘problematic’? Are they not wrong or bogus or false or fraudulent or criminal?
  6. Are there conditions for which medical supervision should not be sought? Which are they?

Yes, to a large extend, quacks make a living by advertising lies. A paper just published confirms our worst fears.

This survey was aimed at identifying the frequency and qualitative characteristics of marketing claims made by Canadian chiropractors, naturopaths, homeopaths and acupuncturists relating to the diagnosis and treatment of allergy and asthma.

A total of 392 chiropractic, naturopathic, homeopathic and acupuncture clinic websites were located in 10 of the largest metropolitan areas in Canada. The main outcome measures were: mention of allergy, sensitivity or asthma, claim of ability to diagnose allergy, sensitivity or asthma, claim of ability to treat allergy, sensitivity or asthma, and claim of allergy, sensitivity or asthma treatment efficacy. Tests and treatments promoted were noted as qualitative examples.

The results show that naturopath clinic websites had the highest rates of advertising at least one of diagnosis, treatment or efficacy for allergy or sensitivity (85%) and asthma (64%), followed by acupuncturists (68% and 53%, respectively), homeopaths (60% and 54%) and chiropractors (33% and 38%). Search results from Vancouver were most likely to advertise at least one of diagnosis, treatment or efficacy for allergy or sensitivity (72.5%) and asthma (62.5%), and results from London, Ontario were least likely (50% and 40%, respectively). Of the interventions advertised, few are scientifically supported; the majority lack evidence of efficacy, and some are potentially harmful.

[Legend to figure above: Percentage of alternative medicine clinic websites advertising at least one of diagnosis, treatment or efficacy for allergy/sensitivity or asthma. Presenting the data in this way demonstrates that the Canadian naturopath, homeopath and acupuncturist websites studied have >50% rates of making at least one health-related claim for both allergy/sensitivity and asthma.]

The authors concluded that the majority of alternative healthcare clinics studied advertised interventions for allergy and asthma. Many offerings are unproven. A policy response may be warranted in order to safeguard the public interest.

In the discussion section, the authors state: “These claims raise ethical issues, because evidence in support of many of the tests and treatments identified on the websites studied is lacking. For example, food-specific IgG testing was commonly advertised, despite the fact that the Canadian Society of Allergy and Clinical Immunology has recommended not to use this test due to the absence of a body of research supporting it. Live blood analysis, vega/electrodiagnostic testing, intravenous vitamin C, probiotics, homeopathic allergy remedies and several other tests and treatments offered all lack substantial scientific evidence of efficacy. Some of the proposed treatments are so absurd that they lack even the most basic scientific plausibility, such as ionic foot bath detoxification…

Perhaps most concerning is the fact that several proposed treatments for allergy, sensitivity or asthma are potentially harmful. These include intravenous hydrogen peroxide, spinal manipulation and possibly others. Furthermore, a negative effect of the use of invalid and inaccurate allergy testing is the likelihood that such testing will lead to alterations and exclusions in diets, which can subsequently result in malnutrition and other physiological problems…”

This survey originates from Canada, and one might argue that elsewhere the situation is not quite as bad. However, I would doubt it; on the contrary, I would not be surprised to learn that, in some other countries, it is even worse.

Several national regulators have, at long last, become aware of the dangers of advertising of outright quackery. Consequently, some measures are now beginning to be taken against it. I would nevertheless argue that these actions are far too slow and by no means sufficiently effective.

We easily forget that asthma, for instance, is a potentially life-threatening disease. Advertising of bogus claims is therefore  much more than a forgivable exaggeration aimed at maximising the income of alternative practitioners – it is a serious threat to public health.

We must insist that regulators protect us from such quackery and prevent the serious harm it can do.
