Novel treatment for autism uses ‘clean room’

With childhood autism cases skyrocketing and no cure in sight, doctors at the Children’s Institute in Pittsburgh are planning on a Hail Mary pass approach to the mysterious disorder — housing young patients for weeks at a time in a pollutant-free “clean room,” in an attempt to detoxify their bodies.

No cause for autism has been found, and debates rage as to whether the brain development disorder is purely genetic or caused in part by environmental factors, including air and food-borne chemicals.

With roots in autism treatment theories that until now have lived mostly on the Internet, the pediatric clean room plan would be the first of its kind in a mainstream American hospital environment.

The Children Institute’s Scott Faber, a pediatrician with several hundred autistic patients and a waiting list six months long, is one of the believers in toxic causes, and the institute is trying to back him with a multimillion dollar test of the novel theory.

Under the plans — developed with help from Duquesne University — autistic patients would live for more than six weeks in a 1,000-square-foot room kept mostly free of harmful chemicals and pollutants, using special air-filtering systems, ultraviolet lights and air locks on doorways.

Furniture, paints, toys and floor coverings would be designed to be toxin-free, and food, clothing and water organic and clean. Doctors would seek to rid patients’ bodies of chemicals and boost their immune systems through natural means such as nutritional supplements and dietary changes.

Basically, it would be pushing a “reset” button on the child’s body, with the hope of wiping autistic symptoms away.

“What we would like to do is have kids live in this wonderful environment where they are exposed to almost none of the Industrial Revolution. And we wonder, if the chemicals come out and the heavy metals come out, will the children start improving?” Faber said.

“Will they start showing signs of clinical improvement, such as language improvement and socialization improvement? Will they become less obsessive? Less fascinated?”

Autism is one of a group of developmental disabilities disorders that cause substantial impairments in social interaction and communication, and are characterized by unusual behaviors and interests. Many people with these disorders also have unusual ways of learning, paying attention and reacting to sensation. Rates have greatly increased in recent years, according to the U.S. Centers for Disease Control and Prevention, though some of the rise may be due to changes in reporting and diagnosing the disorder.

It will require an estimated $500,000 to fully design and at least $1 million in yearly operating support its first three years.

The Children’s Institute plan would be taking what is arguably a fringe movement into the mainstream: It would be the first autism treatment of this kind staged in an American hospital setting. It will be matched with scientific analysis, sensors and video cameras to study the real impacts of detoxification. The data and findings will be shared openly, he said.

The room would house only one patient at a time and have educational and play spaces, and a table for dining. Medical staff, teachers and family would have regular access to the room through an air-locked entrance, and another air lock would separate the room from a kitchen and laundry area. There will be a small bedroom for the child and a couch for a family member to stay overnight.

At the outset, patients would be only the sickest children, who have not responded to other treatments. They would stay six to 12 weeks, allowing an estimated four to six children to be treated per year. (Twenty families have already expressed interest.) After leaving, spaces at each patient’s home would be equipped with lower-level clean technology, such as ultraviolet lights and air filters, and children would continue with special diets.

With so many doubts — and so few answers — about effective autism treatments among the growing community of families affected by the condition, the institute said openness is vital to the experimental method’s success.

“We’re not saying this is the full cause” of autism and related illnesses, Faber said. “Obviously there are multiple causes, and there are going to be found many genetic causes, many environmental causes and many genetic-environmental interactions. But we wonder — we speculate — that it’s possible if we have children living in a unique environment that has not (previously) been created scientifically that we can make a difference.”

Educational, physical, speech and behavioral therapies have long been the traditional treatments for autism, but a growing number of families and researchers have called for further biomedical treatments as well, suspecting there is a chemical side to the disorder.

Parents “research anything they can get their hands on and there are so many things saying ‘Try this or try that’ that aren’t necessarily safe. It’s a frightening thing,” said Kim Aburachis, of Peters, Pa., who has twin 10-year-old boys, Nathan and Tyler, with severe cases of autism. Her boys have seen Faber for more than seven years and are likely to take part in the clean room treatment.

“We’re so excited, so enthusiastic, just for the hope of this,” she said.

Autism and Glutathione

Autism Disorder Risk Increased in Babies of Mothers with

Glutathione S-Transferase P1 Haplotype

Grantees from the NIEHS-supported Center for Childhood Neurotoxicology and Exposure Assessment at the University of Medicine and Dentistry of New Jersey have found a positive correlation between a diagnosis of autism in children and a polymorphism in a gene coding for the enzyme glutathione S-transferase (GST) in their mothers. This finding suggests that autism may be the result of a gene-environment interaction and suggests a possible mechanism for the design of strategies for prevention and treatment.

The researchers determined the frequency of glutathione polymorphisms in 137 members of 49 families with histories of autism disorder. Autism was confirmed using two common diagnostic screening methods. They found that the autism case mothers were 2.7 times more likely to carry the GSTP1*A haplotype. GSTs are active in the detoxification of endogenous compounds such as peroxidized lipids as well as the metabolism of xenobiotics.

If confirmed by additional studies, this finding represents a major step in determining whether autism disorders are the result of gene-environment interactions. It also raises questions as to whether the effect is the result of conjugation of glutathione with toxins. These results may provide insight into the toxins that might cause the effect and could lead to the therapeutic or preventive strategies for autism disorders.

Toxins and the young: new standards needed

Researcher: New toxicant safety standards are needed to protect the young

New toxicant safety standards are needed to protect the young

(PhysOrg.com) — In an invited, peer-reviewed journal article on how prenatal exposure to toxic substances are linked to a host of diseases in later life — from atherosclerosis to cancer — a Cornell toxicologist calls for changing how safety testing is done to better protect infants and children.

Safety testing for environmental chemicals and drugs is routinely conducted on adults, said Rodney R. Dietert, professor of immunotoxicology at the College of Veterinary Medicine, which is hardly relevant for young children or children in utero.

“The developing immune system is more sensitive to toxicants than that of the adult and in ways that cannot be readily predicted by adult safety testing,” said Dietert, whose perspective piece on developmental immunotoxicology (DIT) is the cover story of the January issue (22:1) of the American Chemical Society’s Chemical Research in Toxicology.

“Yet, many chronic diseases that have been increasing in incidence — including childhood asthma and allergies, autism, childhood leukemia, type 1 diabetes, celiac disease, rheumatoid arthritis and lupus — are associated with early life environmental exposures, and they all also have immune dysfunction in common.”

Dietert, who has been studying for more than a decade how toxic substances affect the developing immune system, stresses the need to focus more attention on identifying environmental factors that can damage the immune system during prenatal, infant and juvenile development. Protecting the immature immune systems could not only extend quality of life during adulthood, but also reduce future health care needs.

“The maturing immune system is a vulnerable target for toxicants as it progresses through a series of novel prenatal and perinatal events that are critical for later-life host defense against a wide array of diseases,” said Dietert. “When it is disrupted by exposure to chemicals, all too often the outcome takes the form of persistent immune dysfunction or misregulation. For this reason, the health risks of exposure to toxicants are significantly greater in early life.”

Because DIT is linked to a majority of the most significant childhood chronic diseases, he added, “safety testing for DIT is a pivotal issue in the protection of children’s health.”
