Brief summary
This study aimed to show the effects of hyperbaric oxygen therapy and/or Risperidone in improving symptoms of autism
Detailed description
Autism spectrum disorders (ASDs) are clinical disorders with multiple developmental disabilities in skills associated with overall behavior and communication. The term (ASD) includes Autistic Disorder (AD), Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS), and Asperger's Disorder . Hyperbaric oxygen therapy (HBOT) is a treatment in which patients inside a hyperbaric chamber breathe a concentrated oxygen pressurized more than sea level (1 atmosphere absolute) . It was obvious that autistic children may have some benefits of HBOT by increasing in cerebral perfusion during treatment. Inhalation of more pressurized oxygen might elevate partial pressure of oxygen in the arterial blood, and increased oxygen that reaches the brain . Another mechanism of action of HBOT that it might have anti-inflammatory properties by reduction of pro-inflammatory cytokines, interleukins 1 and 6, interferon-γ, and tumor necrosis factor-α. Furthermore, HBOT might enhance mitochondrial dysfunction, and upregulate the antioxidant enzymes production. Risperidone is a second generation antipsychotic, approved by the Food and Drug Administration (FDA) for treatment of autism-related irritability. Its approved in 2006 only for children not less than 5 years old . This trial aimed to study the effects of hyperbaric oxygen therapy and/or Risperidone in management symptoms of autism.
Interventions
It is antipsychotic drug used by dose: 0.25 mg per day in children weighing less than (20 kg); 0.5 mg per day in persons weighing more for 8 months.
Sessions were done at pressure 1.5 ATA (atmosphere absolute) with 100% oxygen concentration, each lasting for one hour either in multiplace chamber or in monoplace chamber.
control group received non specific multivitamins as placebo for 8 months.

Intervention model description
Children were divided into four groups.Twenty autistic children in each group. They followed up for 2 years.
Eligibility
Inclusion criteria
* age of 5-7 years * weight of at least 15 kg

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Childhood Autism Rating Scale version 2 (CARS2)measured after one year and after two years to compare the effect of hyperbaric oxygen therapy, Risperidone, both of them and the placebo effect | two years | The CARS is a 15 items behavioral rating scale developed to identify autism as well as to quantitatively describe the severity of the disorder. The items are as follows: I. Relating to People; II. Imitation; III. Emotional Response; IV. Body Use; V. Object Use; VI. Adaptation to Change; VII. Visual Response; VIII. Listening Response; IX. Taste; Smell, and Touch Response and Use; X. Fear or Nervousness; XI. Verbal Communication; XII. Nonverbal Communication; XIII. Activity Level; XIV. Level and Consistency of Intellectual Response; and XV. General Impressions. Each item is scored from 1 (no pathology) to 4 (severe pathology) in 0.5 intervals. A total score of 15-29.5 is considered non-autistic to minimal; a score of 30-36.5 is considered mild to moderate autism; a score of 37-60 is considered severe autism (these are based on raw scores) |
