Do you know about the dosage?
In the
Dr Tarello self treatment with potassium arsenite to cure his Staphylococcus bacteremia ME/CFS, he used an intramuscular injection of potassium arsenite 0.5% for 10 days at 1 ml every 12 hours, which I think works out to 5 mg of potassium arsenite given every 12 hours.
I am not sure how to calculate the equivalence of potassium arsenite and
arsenic trioxide, but if we do this in terms of the arsenic content of these two molecules, then the following calculation can be considered:
The potassium arsenite formula is AsKO2, which contains 51.3% arsenic by weight (using a
molecular mass calculator). The arsenic trioxide formula is As2O3, which contains 75.7% arsenic by weight. So 5 mg of potassium arsenite would contain the same amount of arsenic as
51.3 / 75.7 x 5 = 3.4 mg of arsenic trioxide.
So I would estimate that Tarello and his wife took the equivalent of 3.4 mg of arsenic trioxide twice daily for 12 days.
In the
murine antiviral study, they used a daily dose of 1 mg of arsenic trioxide per kg of body weight, given for 7 days. To convert that to a human dose, you divide by the mouse-to-human conversion figure of 12.3 (see page 7
here). So the equivalent human dose would be 1 / 12.3 = 0.08 mg per kg body weight. Thus for an 80 kg human, that would be a dose of 80 x 0.08 =
6.4 mg of arsenic trioxide once daily for 7 days.
However, given that arsenic trioxide treatment can cause differentiation syndrome, which can be fatal if not treated, this does not sound like a drug you can use without medical supervision.
Also, remember that in the mouse study, the arsenic trioxide is used to fight an acute coxsackievirus B infection. Whereas in ME/CFS, there is a chronic infection, which takes a different form (chronic CVB infection lives inside cells on a long-term basis as a non-cytolytic infection). So whether the arsenic trioxide would be as effective for chronic CVB is another issue.
Furthermore, from experiments with interferon as an antiviral treatment for CVB ME/CFS, we know this often dramatically improves ME/CFS (enabling bedbound patients to go back to work). However, after several months to a year, these patients relapse again, because the interferon does not quite eliminate all the virus from the body, so the virus slowly returns. So the same might happen with arsenic trioxide: it might work initially, but the virus may come back after some months. Which would mean that the arsenic trioxide treatment would be a waste of time.
However, because arsenic remains within cells on a long-term basis, it's conceivable that its continued presence in the cells might have some ongoing protective antiviral effect, stopping the virus from returning. But this is just pure speculation. It's also the continued presence in cells which increases lifetime cancer risk.
