Parents say that the drug outside the label helps one boy with autism to speak. But experts want more data.

Caroline Connor’s concerns about her son’s development started on his first birthday, when she noticed that he did not speak or use any words. Their pediatrician was not worried, but the delay of speech continued. In 2½, Mason was Diagnosis of autism.

Connors went on a mission, and searching for anything that would help.

“We have just started searching on our own,” Caroline said.

Richard Free, a children’s neurologist, is one of the many doctors looking for treatments that can help Children with autism. It studies Leucovorin, which is an inexpensive general drug derived from folic acid, also known as folate or vitamin B9. Leucovorin is currently described to relieve the side effects of the chemotherapy of cancer. Pregnant women are prescribed vitamins with folic acid to prevent nervous tube defects. The nervous tube develops into the brain and spinal cord.

“Leucovorin is not a treatment for autism, but” it can have a significant effect on a very good percentage of children with autism. “

This week, the Food and Drug Administration (FDA) has started the approval process on Leucovorin as a treatment for autism, although there are no major clinical experiments in stage 3.

“We have some good initial evidence that leuucovorin helps,” said Free. “But the FDA usually wants to see at least two large stage 3, and the dominant clinical trials that are dominated by fake. At the present time, we only have stage 2b studies, more research is needed to answer the main questions, such as how to dominate them properly, when you start, and any children will benefit more.”

The theory behind the use of the drug for autism assumes that some children have a blockage in the transmission of folic acid to the brain, which is likely to contribute to some neurological problems associated with the disorder. Leucovorin goes beyond this blockage and can help some children with autism improve their ability to speak. Three random experiments governed by Leucovorin to treat autism showed positive effects on speech.

Frex is cited with five blind -controlled studies so far, all positive, despite various doses and in different groups. However, he said: “The evidence is not yet as it is usually for a drug.”

Free said that he was “disappointed” because his group did not receive funding from the National Institutes of New Health Autism data initiative And it has not been consulted about the upcoming Leucovorin experiences design. “It is strange, because I have been leading this work for decades,” he pointed out.

Folic acid deficiency cerebral acid

Folic acid deficiency was cerebral, or a lack of folic acid in the brain, He prescribed it for the first time from the doctor and researcher Vincent Ramickers. Ramakers found that some children with nervous growth disorders have natural levels of folic acid in the blood, but low levels in the spinal fluid. Then he collaborated with researcher Edward Kawadros, who was studying how autoimmune disorder could block folic acid to the brain. Ramaekers and Quadros found that antibodies against alpha folate receptors (FR⍺), which transmit folic acid from blood to the brain and placenta, may cause abnormal fetus’s brain development and some autism spectrum disorders.

One study found that more than 75 % of children with autism spectrum disorder FR⍺ was antibodiesCompared with 10 % -15 % of healthy children. There is evidence of a Family or genetic readiness To develop antibodies. While environmental and immunity defect may also play a role, there is no evidence indicating that vaccines cause the development of antibodies to the FR⍺.

The brain contains a backup system to the FR⍺ known as a low -fusiness carrier, or RFC. RFC is not effective as a carrier like a FR⍺, but leucovorin, also known as phonic acid, can be transmitted to the brain. In enzymes in the brain, yocoforin turns an active form of folic acid.

Treatment with leucovorin Increases brain levels of folic acid In children with a deficiency of folic acid, or CFD. In one of the studies led by Free, a third of these children Experienced improved In their speech and other behavior when they are treated with leucovorin. Two random experiences in France and India showed similar results. A Antibodies to Flat Records (FRAT) Available Determination of children It may likely respond to the treatment of leucovorin.

The Frye team also identified the new potential vital indicators, such as soluble folate protein protein, which can predict children who need higher doses.

Free indicated that there are many nuances of CFD treatment with Leucovorin, including adding auxiliary treatments to improve mitochondria.

Side effects associated with licomovorin are light. Some children suffer from hyperactivity during the first few weeks of treatment, but usually decline within a month or two. A similar pattern is seen with other B vitamins.

Mason “Small Hope bottle” by Mason

The first words of Masson Connor came just three days after the start of taking Locovorin at the age of three.

Doctors can currently prescribe the drug only for autism outside the label, which means reusing an approved drug for one condition for another treatment.

“We have done the science, and the next step is that we want to get more funding so that we can already get it accredited from FDA,” Frei said.

Welcomes The last FDA interest But warning that “it may have been a little premature”, given the gaps in knowledge and the need to teach the doctor about how to properly prescribe Leuucovorin in autism.

There is one big problem. “Leucovorin is an old drug, and you can get it at a very low price. So no one will make a lot of money on it. So there is no reason for investment,” Freuvorin said.

Double the challenge: the width and quality vary. “Yokovorin is a year, and different manufacturers use different additions,” explained Frex. “Some products do not tolerate children with autism well.”

Fry is used to recommending that patients use the general shape of the West-Wark Pharmaceuticals, an American subsidiary of HICA, but he said: “He has run out early this year. At the present time, the only reliable source is through a high-quality vehicle pharmacy that knows how to make children with Martva.” Frye is to create a profit company to manufacture the correct form of Leucovorin for children with autism.

About 20 % -30 % of all medical prescriptions in the United States are outside the designation, according to non -profit organizations Every treatment. This is often done as there are more than 14,000 known human diseases with the absence of approved drugs from the FDA (FDA) for its treatment. Medicines such as leucovorin are often used outside the designation because doctors believe that benefits outweigh the risk. However, there is often a limited awareness about these treatments, so it may not be used.

David VaginbumThe founder and head of every treatment said that he was “literally alive today from a medicine for treatment” after he was diagnosed with a rare disease that resembles the cancer that almost killed him. His research in his illness led to a medicine for another condition.

“It is heartbreaking to think about the medications that are on the rack of the pharmacy while someone suffers from illness,” said Waginbum.

All artificial intelligence treatment is used to avoid available medical data on diseases and treatments to detect possible matches. Every treatment highlights Frye, Ramaekers, Quadros and others on Leucovorin work in the treatment of autism.

“I think our system is only defective and there is this main gap where the pharmaceutical companies are great in developing new drugs for new diseases, and we are a really poor system in searching for new diseases of old drugs. For this reason we started every treatment – to cancel hidden treatments,” said Waginbum.

Mason is now at the age of five, and the plan is to start the prevailing kindergarten this fall – towards a new path by old medicine.
