Clinical Trial Summary

A child and their parent were asked to participate in a research project that sought to study whether sleeping in a very clean environment for 14 days improved the elimination of chemicals and metals from the child's body. The child had an approximately two hour evaluation to confirm his or her diagnosis of Autism or Pervasive Developmental Disorder. Not Otherwise Specified. When one of these diagnoses was confirmed the child was scheduled to spend 14 nights sleeping in a very clean environment in a specially created room at The Children's Institute.

Several hours prior to the first night the child slept in the clean room the child's mother, father, or guardian filled out behavioral rating scales about the child with the assistance of the study's research coordinator. The child also had approximately two tablespoons of blood drawn from an arm and a few inch sample of hair was taken from the back of the child's head. The child and a parent or guardian arrived at The Children's Institute about one half hour prior to the child's normal time of settling for bed for 14 consecutive nights. The child and a parent or guardian slept in the clean room, wearing the provided very clean clothes and sleeping on special mattresses and sheets each night for 14 consecutive nights. The child and parent were observed by a nurse through a window during the time in the clean room. The child and parent participated in regular daytime activities during these 14 days of the study. On the morning after the last night the child and a parent or guardian slept in the clean room a parent or guardian filled out behavioral rating scales with the help of the research coordinator. Approximately two tablespoons of blood were drawn from an arm and a few inch sample of hair was obtained from the back of the child's head, at The Children's Institute or at home.


Description:

Autism spectrum disorders are characterized behaviorally by expressive language and social deficits, the performance of stereotypic and repetitive behavior patterns, and abnormal cognitive functioning. Children with autism spectrum disorders often do not have known anomalies seen on genetic testing. An emerging paradigm suggests that the majority of children with autism are displaying a pattern of genetic / environmental interaction that make them susceptible to difficulties with detoxification of the heavy metal and chemical environment. Children with autism demonstrate increased difficulty with the performance of methylation and sulfation required for the elimination of fat soluble chemicals from human tissues. These children also commonly display dysfunction of their metalloprotein systems necessary for the elimination of heavy metals such as mercury and arsenic from their bodies.

This study sought to provide 10 children with autism an opportunity to sleep in a clean room environment, a hospital room that was modified to remove nearly all traces of particulate matter, chemicals, and heavy metals, for a 2 week period while going about their normal activities during the day. In the clean room, the children slept on bedding and wore clothes that did not release any toxins. This room created a concentration gradient for chemical and heavy metal toxins that may have allowed these toxins to leave the children's bodies during their stays.

The children's parents filled out seven rating scales, including the Aberrant Behavior Checklist, immediately before and after the 2 week sleeping periods. The children had blood samples taken before and after the 2 week sleeping experiences that measured biomarkers of metalloprotein (heavy metal elimination) and immune functioning, such as the plasma zinc/serum copper ratio and T and B cell subsets. Red blood cell and hair concentrations of toxic heavy metals such as mercury, arsenic, and chromium 6, and red blood cell concentrations of chemicals implicated in contributing to human pathology, including polychlorinated biphenyls (PCBs), polybrominated diethyl ethers (PBDEs), and phthalates were determined before and after the sleeping experiences. These pre and post stay variables were statistically compared, and it was hypothesized that the children's red blood cell concentrations of toxins would be significantly reduced while their hair concentrations of toxins would be significantly increased after their sleeping experiences in the clean room, supporting the concept that the clean room promoted the release of heavy metals and chemicals from their bodies. This one year study was a proof of concept cohort study.
