Test a large number of people for as many common toxins as possible, including things like DDT, Dieldrin, HCBs, PCBs, Mirex, Lindane, Mevin-phos, p-dichlorobenzene, Pentachlorophenol, Carbaryl, Toxaphene, and look for any correlations with symptoms. Not necessarily limited to ME symptoms, it can be a shotgun approach for many chemicals and many conditions. Any promising findings can then be studied more carefully.
The above list of chemicals is from
Four Cases of Pesticide Poisoning, Presenting as “ME,” Treated with a Choline and Ascorbic Acid Mixture, a paper from 2000 with four case reports. Each person had been exposed to large amounts of different pesticides and was experiencing an ME-like illness. Blood tests showed different combinations of the above chemicals. After treatment with choline and vitamin C, the levels of the above chemicals were greatly decreased as were their symptoms.
Table showing blood levels of chemicals in the four patients over time:
Most of the above chemicals are organochlorine pesticides. I think most or all of the above chemicals are fat soluble and can persist for a long time in the body, and many or all have been banned in some jurisdictions due to health effects. I think all four people had no idea there could be a connection between the chemicals and the symptoms until the doctor suggested it.
One example:
In response to further questioning about his two weeks in South Korea, he remarked that the hotel was full of rats, and, on my enquiring about insecticides, he told me that a wagon came round a night to spray the streets ‘‘to keep down the vermin.’’ On examination, the only positive signs were a mild hypertension, B.P. 160/110 mmHg, some redness of the optic fundi with early vascular cuffing and a muscular jitter in his legs. On the ME Score Chart, he scored 18 out of 21, which is a positive score. Since ME/CSF is an organic illness with a number of possible causes, I decided to have his blood analyzed for evidence of pesticide intoxication. The report by Biolab Medical Unit on a sample taken on 9 August 1996, the results of which are shown in the Table 1, showed a level of 2.8 g/l of Polychlorinated Biphenyls (PCBs), well above background levels. Further gas chromatographic separation indicated two compounds with 32% and 42% chlorine content, respectively. There was also evidence of some exposure to the less persistent organochlorine Mirex.
If this person potentially got ME from visiting a hotel in South Korea for two weeks because of chemicals that persisted in his body, how many people that live their whole lives in that area getting constant exposure have similar symptoms that no one has realized might be linked to the pesticides? If in places where they were banned, testing older people may show they still have relatively high levels from before the ban.
Organophosphates, purportedly a safer form of pesticides, have been linked to
gulf war illness,
psychiatric disorders, and
fatigue, and are still used in many places.
I would like to see a study looking at a large number of people (>1000), maybe only older age, some healthy, some with chronic conditions, such as ME, Parkinson's, Alzheimer's, arthritis, asthma, or depression, and test them all for as many chemicals as possible, prioritizing for chemicals that are more affordable to test, that are more commonly used, (or have been commonly used in the past if they persist for a long time), that are most likely to be harmful to health (e.g. chemicals where acute exposure is definitely harmful, or related compounds to these), and where a significant portion of the population is known to have non-zero levels (like microplastics). Analyze the results for any potential correlations to symptoms to then pursue more targeted research on any chemicals showing correlations.
