Immunological treatments for autism.
Early immune-fix ideas for autism sounded hopeful, but follow-up reviews say evidence is still too weak to guide therapy.
01Research in Context
What this study did
The author gathered papers about immune problems in children with autism.
He listed shots, pills, and IV drips doctors had tried to fix those problems.
No kids were treated in this paper; it is a story-style review only.
What they found
The review says immune markers look odd in many autistic children.
It ends with a maybe: biological fixes could help, but proof is thin.
How this fits with other research
Two years later Krause et al. (2002) looked at the same shots and IV drips.
They said the proof is still weak and told clinicians to stay with behavior plans.
That 2002 paper acts like a sequel that corrects the first story.
More recent work keeps the biology talk alive.
Lu et al. (2025) show gut bugs can calm tummy pain, yet Tan et al. (2021) say those same probiotics do not touch autism behaviors.
The pattern: body-based treatments keep showing small, narrow wins, not broad autism cures.
Why it matters
You will hear parents ask about immune shots, special diets, or probiotics.
This 2000 review is the seed for those questions, but later updates say the data are still soft.
Stick to behavior plans that have solid evidence, and refer medical questions back to the pediatrician.

03Original abstract
Several investigators, including ourselves, have reported significant changes in various immune responses in children with autism. These changes demonstrate dysregulation of the immune system (deficiency in some components of the immune system and excesses in others). In addition, certain genes in the major histocompatibility complex (that regulates immune responses) appear to be involved in autism. Based upon immunological abnormalities, various treatment modalities have been applied to children with autism. In this brief review, these immunological changes and various biological therapies are analyzed and summarized.
