German Medical Association warns: “Swine flu vaccine” unsuitable for patients suffering from environmental diseases and other chronic multi-system illnesses

“Swine flu vaccine” unsuitable for patients suffering from environmental diseases

Press release of the German Professional Association of Environmental Medicine (Deutscher Berufsverband der Umweltmediziner – DBU)

from 26. October 2009

Swine flu vaccine is unsuitable for patients with environmental diseases and other chronic multi-system illnesses.  Pandemrix® poses substantial health risk with respect to mass immunization programs due to the lack of proof of safety.  Because of the producer’s release from liability by the German Federal Government (BRD), the risk of adverse reactions and/or permanent damage due to the vaccine rests with the patient.

The German Professional Association of Environmental Medicine (DBU) has, in spite of press releases from the BRD, the Paul-Ehrlich-Institute, as well as the vaccine producer’s assurances of safety, serious concerns relating to Pandemrix® (GlaxoSmithKline), the only vaccine which has been approved for mass vaccination by the BRD.

The DBU discusses at this point neither the medical use of immunization in general nor the necessity of such measures in the, up until now, mild course of the swine flu pandemic.

Our criticism is directed only against the pandemic vaccine Pandemrix®.

  • There exists considerable doubt as to the effectiveness of the vaccine: during the licensing phase, the vaccine tested had a 40% higher portion of virus antigen (5. 25µg) than the vaccine (3.75µg) now being delivered. An unequivocal consensus has not been reached as to whether the vaccination should be given once or twice a season !!!
  • There exists considerable doubt concerning the safety of the adjuvanted active amplifier since it is being used for the first time. The vaccine contains 27.4mg AS03, an emulsion of polysorbate, squalene and tocopherol. Sufficient studies are lacking, because in the test phase, only the development of antibody titers was determined as a surrogate criterion, and not any potential adverse reactions.
  • The producer as well as government agencies have concealed the fact that squalene, if used subcutaneously or intramuscularly is an inflammatory immune activation immunogen, unlike when ingested. (Squalene is, among other things, for example, naturally contained in olive oil.)
  • Autoimmune diseases can be provoked by squalene; already existing ones can be activated. Squalene has been connected with the emergence of Guillan-Barré Syndrome (GBS) and is now considered a trigger for Gulf War Syndrome (GWS). In animal studies squalene brought on rheumatoid arthritis.
  • Squalene from food sources is mainly incorporated into membranes in the body. The production of squaline antibodies resulting from an immunization sets off chronic inflammation of the membranes, which explains diseases such as Gulf War Syndrome and also degenerative neurological diseases such as Multiple Sclerosis, Amyotrophic Lateral Sclerosis, Chronic Inflammatory Demyelinating Polyneuropathy and Guillan-Barré Syndrome.
  • The delivery of vaccine in multiple dose ampules is obsolete. In single dose ampules the mercury used for preservation, as in thimerosal – which is included in Pandemrix – would be unnecessary.  Also, mercury has been proven to set off autoimmune diseases.
  • Since the vaccine has not been tested on either young children or pregnant women (Ethics Commission objection), the call to give preference in the first phase of vaccination to precisely this particularly endangered segment of the population represents an improper and totally unjustifiable field test.
  • The vaccine poses a higher risk than the swine flu itself for patients with environmental illness and for patients with compromised immune systems (e.g. AIDS).
  • The vaccine producer GlaxoSmithKline (GSK), according to the contract with the BRD, is largely exempt from liability. In case of damage from the vaccination, the affected vaccinee would have to sue the government and therefore the country of Germany, usually a futile exercise.
  • To avoid the trap of liability, the doctor giving the vaccination must meticulously inform the patient of all risks concerning the vaccination and the vaccine. It is recommended to give this information in the presence of an assistant and to have it be confirmed by the patient’s signature. The explanation should also include the liability features. Also the indication that other, lower risk vaccines are available in Europe and that due to a faulty decision by the German government, they are currently not available to the German population. This information should definitely be included in the explanation.

For general and environmental health considerations the DBU urgently advises against carrying out a vaccination with Pandemrix® !

Mercury exposure, nutritional deficiencies and metabolic disruptions may affect learning in children

Children with learning disabilityAmong dietary factors, learning and behavior are influenced not only by nutrients, but also by exposure to toxic food contaminants such as mercury that can disrupt metabolic processes and alter neuronal plasticity. 

Neurons lacking in plasticity are a factor in neurodevelopmental disorders such as autism and mental retardation. Essential nutrients help maintain normal neuronal plasticity. Nutritional deficiencies, including deficiencies in the long chain polyunsaturated fatty acids eicosapentaenoic acid and docosahexaenoic acid, the amino acid methionine, and the trace minerals zinc and selenium, have been shown to influence neuronal function and produce defects in neuronal plasticity, as well as impact behavior in children with attention deficit hyperactivity disorder. 

Nutritional deficiencies and mercury exposure have been shown to alter neuronal function and increase oxidative stress among children with autism. These dietary factors may be directly related to the development of behavior disorders and learning disabilities. 

Mercury, either individually or in concert with other factors, may be harmful if ingested in above average amounts or by sensitive individuals. High fructose corn syrup has been shown to contain trace amounts of mercury as a result of some manufacturing processes, and its consumption can also lead to zinc loss. Consumption of certain artificial food color additives has also been shown to lead to zinc deficiency. Dietary zinc is essential for maintaining the metabolic processes required for mercury elimination.

Since high fructose corn syrup and artificial food color additives are common ingredients in many foodstuffs, their consumption should be considered in those individuals with nutritional deficits such as zinc deficiency or who are allergic or sensitive to the effects of mercury or unable to effectively metabolize and eliminate it from the body.

Pesticides exposure linked to suicidal thoughts

Pesticides exposure linked to suicidal thoughts

A new study in China has found that people with higher levels of pesticide exposure are more likely to have suicidal thoughts. The study was carried out by Dr Robert Stewart from the Institute of Psychiatry at King’s College London together with scientists from Tongde Hospital Zhejiang Province. 

The agricultural pesticides commonly used in China are organophosphates which are in wide use in many lower income countries but have been banned in many Western nations. It is well known that they are very dangerous if ingested as an overdose but there is also biological evidence that chronic low-grade exposure to these chemicals, which are very easily absorbed into the body through the skin and lungs, may have adverse effects on mental health. This study is the first epidemiological evidence to suggest possible effects on suicidal thoughts. 

The study was carried out in central/coastal China, a relatively wealthy area with a rapidly developing economy. In a very large survey of mental health in rural community residents, participants were also asked about how they stored pesticides. The study found that people who stored pesticides at home, i.e. those with more exposure, were more likely to report recent suicidal thoughts. Supporting this, the survey also found suicidal thoughts to be associated with how easily accessible these pesticides were in the home and that the geographic areas with highest home storage of pesticides also had highest levels of suicidal thoughts in their populations. 

Given the high level of pesticide exposure and the high suicide risk in rural China, clarification of the causal mechanisms underlying this association and the development of appropriate interventions should be priorities for public health and health policy. 

Dr Robert Stewart comments: ‘Organophosphate pesticides are widely used around the world although are banned in many countries because of their risk to health. They are particularly lethal chemicals when taken in overdose and are a cause of many suicides worldwide. Our research findings that suggest that higher exposure to these chemicals might actually increase the risk of suicidal thoughts provides further support for calls for tighter international restrictions on agricultural pesticide availability and use.’

Dr Jianmin Zhang, Associate Chief Psychiatrist, Tongde Hospital of Zhejiang Province, and Vice Director, Zhejiang Office of Mental Health, China added: “The findings of this study suggested potential causal links and might partially account for the much higher incidence of suicide in rural than urban areas of China. However, further studies particularly with more precisely defined and assessed exposure are critically needed, as awareness of safer access to pesticides is important both to policy-makers and pesticide users.”

Notes:

Pesticide exposure and suicidal ideation in rural communities in Zhejiang province, China by Jianmin Zhang, Robert Stewart, Michael Phillips, Qichang Shi & Martin Prince was published in the October issue of the WHO Bulletin. The full article can be accessed on http://www.who.int/bulletin/volumes/87/10/08-054122.pdf 

The analysis involved data from a survey of a representative sample of 9,811 rural residents in Zhejiang province who had been asked about the storage of pesticides at home and about whether or not they had considered suicide within the two years before the interview. The Chinese version of the 12-item General Health Questionnaire (GHQ) was administered to screen for mental disorder.

MCS – Multiple Chemical Sensitivity – A Disease Caused by Toxic Chemical Exposure

Breakthrough study on Multiple Chemical Sensitivity shows MCS is an epidemic caused by toxic chemicals; peer-reviewed paper is published in prestigious toxicology reference work.

Dr. Martin Pall A major paper on multiple chemical sensitivity by Professor Martin L. Pall is to be published October 23, 2009 as chapter XX in a prestigious reference work for professional toxicologists, “General and Applied Toxicology, 3rd Edition” (John Wiley & Sons).  Multiple chemical sensitivity (MCS) is also known as chemical sensitivity, chemical intolerance and toxicant-induced loss of tolerance, with this last name emphasizing the role of chemicals in initiating cases of this disease.  Pall’s  paper, entitled Multiple Chemical Sensitivity: Toxicological Questions and Mechanisms, establishes five important facts about  MCS:

1. MCS is a stunningly common disease, even more common than diabetes.  This has been shown in a series of nine epidemiological studies from the U.S. and one study each from Canada, Germany, Sweden and Denmark.  In the U.S., approximately 3.5% of the population is affected by severe MCS, with much larger numbers, at least 12% of the population, being moderately affected.  MCS is, therefore, a very large international disease epidemic with major implications in terms of public health.

2. MCS is caused by toxic chemical exposure.  Cases of MCS are initiated by exposure to seven classes of chemicals.  These include three classes of pesticides and the very large class of organic solvents and related compounds.  In addition, published studies implicate mercury, hydrogen sulfide and carbon monoxide as initiators.  All seven of these classes of chemicals have been shown in animal studies to produce a common response in the body, excessive activity of a receptor in the body known as the NMDA receptor.  Furthermore animal studies have demonstrated that chemicals belonging to each of these seven classes can have their toxic responses greatly lowered by using drugs that lower this NMDA response.  Because excessive NMDA activity is implicated in MCS from other studies, we now have a compelling common response that explains how such diverse chemicals can produce the disease that we call MCS.

3. The role of chemicals acting as toxicants in MCS has been confirmed by genetic studies.  Four such studies have shown that genes that determine the rate of metabolism of chemicals otherwise implicated in MCS, influence susceptibility to becoming ill with MCS.  These four studies have been published by three research groups in three countries, the U.S., Canada and Germany, have collectively implicated six genes in determining susceptibility to MCS.  Each of these six genes has a role in determining the rate of metabolism of MCS-related chemicals.  The German studies by Schnakenberg and colleagues are particularly convincing on this because of the extremely high level of statistical significance of their studies implicating four of these six genes. There is only one interpretation for the role of these six genes in determining susceptibility to MCS.  It is that chemicals act as toxicants in initiating cases of MCS and that metabolizing these chemicals into forms that are either less or more active in such initiation, influences therefore, the probability that a person will become ill with MCS.  It is clear, therefore, that MCS is a toxicological phenomenon, with cases being caused by the toxic response to chemical exposure.

4. We have, a detailed and generally well supported mechanism for MCS.   This mechanism explains both the high level chemical sensitivity that is the most characteristic symptom of MCS, as well as many other symptoms and signs of this disease, can be generated.   This mechanism is centered on a biochemical vicious cycle, known as the NO/ONOO- cycle, which interacts with other mechanisms previously implicated in MCS, notably neural sensitization and neurogenic inflammation.  These act locally, in various tissues of the body, to generate local sensitivity in regions of the brain and in peripheral tissues including lungs, upper respiratory tract and regions of the skin and the GI tract.  Because of this local nature, different MCS patients differ from one another in their sensitivity symptoms, because the tissues impacted differ from one patient to another.  In addition to the evidence discussed above, this general mechanism is supported by various physiological changes found in MCS and in related illnesses, by studies of MCS animal models, by objectively measurable responses of MCS patients to low level chemical exposure and by therapeutic responses reported for MCS and related illnesses.

5. For over 20 years, some have falsely argued that MCS is a psychogenic disease, being generated in their view by some ill defined psychological mechanism.  However this view is completely incompatible with all of the evidence discussed earlier in this release. While such incompatibility is more than sufficient reason to reject these psychogenic claims, the MCS toxicology paper lists eight additional serious flaws in the psychogenic arguments.  There is a long history of false psychogenic claims in medicine, where such diseases as asthma, autism, Parkinson’s disease, ulcers, multiple sclerosis, lupus, interstitial cystitis, migraine and ulcerative colitis have been claimed to be generated by a psychological mechanism.  The 2005 Nobel Prize in physiology and medicine was give to Drs. Robin Warren and Barry Marshall for showing that ulcers are caused by a bacterial infection, and are not of psychogenic origin.  It is clear, now, that MCS is physiological disease initiated by toxic chemical exposure that has been falsely claimed to be psychogenic.

Air Pollution Adversely Affects Olfactory Function and Intranasal Trigeminal Sensitivity

Air Pollution in Mexico City

Surprisingly little is known about the effects of big-city air pollution on olfactory function and even less about its effects on the intranasal trigeminal system, which elicits sensations like burning, stinging, pungent, or fresh and contributes to the overall chemosensory experience. 

Using the Sniffin’ Sticks olfactory test battery and an established test for intranasal trigeminal perception, we compared the olfactory performance and trigeminal sensitivity of residents of Mexico City, a region with high air pollution, with the performance of a control population from the Mexican state of Tlaxcala, a geographically comparable but less polluted region. 

We compared the ability of 30 young adults from each location to detect a rose-like odor (2-phenyl ethanol), to discriminate between different odorants, and to identify several other common odorants. The control subjects from Tlaxcala detected 2-phenyl ethanol at significantly lower concentrations than the Mexico City subjects, they could discriminate between odorants significantly better, and they performed significantly better in the test of trigeminal sensitivity. 

We conclude that Mexico City air pollution impairs olfactory function and intranasal trigeminal sensitivity, even in otherwise healthy young adults.
