There is a drug called Pyrimethamine. This drug is used by doctors to treat specific types of infections called malaria and toxoplasmosis in children and babies. Laboratory test tube studies have shown that Pyrimethamine can help the Hex A enzyme to function in a normal manner. If Hex A can function normally in presence of Pyrimethamine, this drug should be able restore the brain malfunction of these patients since Hex A can now efficiently break down GM2-ganglioside with Pyrimethamine treatment.
Doctors afraid of litigation will not tell us about this because it is not FDA approved, like anything that is being trialed will not be FDA approved for 10-20 years, by then we would all have watched our children die, horrible painful deaths, while we stand by and hold their hands……
If anything can make a difference to these children of ours then it is worth everything.
I have attached the original Pyrimethamine treatment information for who ever is interested in trying to help their child if possible, (PYR-EET-07).

They are finding that Pyrimethamine is also working on some of the mutations that they thought it would not work on. And although targeted at adults, it worked for Artemissia.
Professor Don Mahuran based at the University of Toronto and The Hospital for Sick Kids, Toronto and Professor Kolodny from New York University are two of the leading researchers on Pyrimethamine, and very approachable. NTSAD has all their details. Professor Barbara Shapiro is from the
Artemissia was born on the 12th September 2007.
We came home to wait out the end in Palliative Care just before christmas 2009, she was totally blind, deaf, mute and paralyzed, with a massive cocktail of medications that included Morpheine 24 hr, extra Morpheine, back up anti-convulsants etc. etc.
With adverse events daily, we were using a lot of medications.
Because of the late diagnosis here Artemissia's condition had totally destroyed her Central Nervous System totally, Artemissia was essentially gone.
In February 2009 Artemissia was close to dying, we began the Pyr treatment Artemissia was blind, totally deaf, totally paralyzed and on continual morpheine doses. We had no choice but to try or Artemissia would not have made it through the first half of 2009.
We had to wait 9 months for the mutation test results but Artemissia would not have survived, we put our faith in god and did the only thing we could, we started Pyr, and it worked. The mutation test came back and 1 of her 2 mutations was known to work with Pyrimethamine. It turned out that our faith and prayers were answered.
We started her on Pyrimethamine on the 6th of February 2009 and within 4 weeks we were having much fewer adverse effects, seizures or convulsions.
By July 2009 we had removed the daily Morpheine from the cocktail 2ml per week; we used none from then.
(I can send the spreadsheet showing the summary of those early days, if you look at it you see all the columns showing, medications, extra-meds, pain, and seizures, as the treatment took effect you can see those columns clearing with time, also I can send Artemissia’s first Daily Plan so you can see the cocktail of drugs in the beginning).
Artemissia was still on her daily medication regime for seizures, occasional anti-biotic for infections, but essentially much, much more stable.
By mid 2010 we had no more need for the Clonazepam (Rivotril), and by December 2010 the Phenobarbitone withdrawal was nearly complete.
With the Pyrimethamine stopping the progress of the disease we then had the task of restoring her Central Nervous System and managing her Respiratory system. The CNS was coming back as Neuronal Regeneration was occurring because as the disease’s progress halted, the body was repairing the damage. I studied what I could find on Neuroplasticity and applied some elementary exercises which helped begin motor skill re-development.
We were over the moon; the doctors here could see the improvements and were happy.
Artemissia could hear loud to medium noises, her eyes shone, no longer rolling upwards, she was so much more aware and she responded to light and colours more. The Pyr treatment and physio regime had worked wonders against the paralysis, her fingers no longer clenched unless she was squeezing our fingers; “foot drop” was easier to manage with feet looser and not so stiff.
The foot tremors from Clonus had nearly all gone, and she was making sounds like trying to communicate. Artemissia responded to love/cuddles with beautiful sighs. Even the Cherry Red spot in the macular had diminished significantly.
The secretions were easier to manage but build up of mucous in the chest was still the major issue and we kept her in the centre of our house with one of us by her side 24/7.
We rotated the shifts and she had a very busy schedule each day.
I have attached a day sheet so you can see how an average day was managed.
If we had known earlier about Pyr, Artemissia would not have so much damage to her Respiratory and Central Nervous Systems.
"DARAPRIM" is the MIMS name of the tablet that contains the PYR; we looked into the MIMS and saw the adverse reactions list, dosing recommendations etc.
Please remember that every person will be different in always, from the mutation itself to the current condition of each individual.
You can download a Daraprim fact sheet online.
I can also provide a copy of a day sheet showing how we gave her the PYR with Folic acid twice daily. PYR reacts with one of our anti-seizure meds, the Phenobarbitone, but we managed that by spreading the doses of Phenobarbitone and Pyrimethamine as far apart as possible from each other over the 24 hour daily dosing period. The PYR dose we have found should not exceed a rate of 1mg, per kilogram of body weight, per day, if that happens it will not work.
Splitting the dose works so much better than single daily dose, it stops any vomitting and works better because it has a working life of 4-5 hrs, after that it's not working for the rest of the day. So splitting it in half and giving twice daily gives us 2 peaks a day.
It must be given with Folic acid or Folinic acid which will be on the instructions. Artemissia reacted adversely to Folinic, so Folic works for her.
Each person is different but the basics are there, you just have to tweak things to suit each individual.
We always made sure that she had been back on her milk for at least an hour prior to giving PYR and this was given with lots of water, perfectly smooth on her tummy.
The PYR was a miracle to us, Professor Mahuran and his colleagues are legends. In our case he did not think it would work at all, and we didn't have Artemissia's mutations which were months away.
He had advised us, as doctors do, against using the PYR prior to getting our mutations analyzed, but we had run out of time, every day the damage continued, our gut said go, so we did, very carefully monitoring everything with the Day Sheets.
Unfortunately Artemissia’s Respiratory condition had progressed too far before we had a diagnosis and could find out about the Pyr ourselves, that Bronchial damage was what eventually led to our loss of Artemissia.
The Pyr is the most promising, least invasive, and it can keep children from deteriorating further until other treatment options can be further researched.
