The use of every treatment in individuals with autism is “off-label” except for
risperidone for the treatment of irritability

Autism: Pathophysiology Cerebral hypoperfusion Inflammation
– Cerebral– Gastrointestinal
Dysbiosis Mitochondrial dysfunction Oxidative stress Impaired glutathione production Environmental toxicant exposures
Study Descriptive Terms
Prospective: planned ahead of time Randomized: participants assigned to a
group by random allotment Double-blind: Neither participants nor
researchers know group assignment Placebo-controlled: A placebo is given to
one group of participants Cross-over: placebo group crosses over
and gets treatment
Placebo Effect
As high as 30-37% in several studies in children with autism
Points to need for double-blind, placebo-controlled studies
However, also need to treat children now, and cannot always wait for these types of study
Need to evaluate the risk/benefit ratio of each treatment
Evidence-based Medicine: Strength of Evidence (Efficacy)
A: Supported by at least 2 prospective randomized controlled trials (RCTs) or 1 systematic review
B: Supported by at least 1 prospective RCT or 2 nonrandomized controlled trials
C: Supported by at least 1 nonrandomized controlled trial or 2 case series
D: Troublingly inconsistent or inconclusive studies or studies reporting no improvements
Caveat
Double-blind, placebo-controlled studies can cause you to lose sight of the individual patient– e.g., DMG: 2 negative double-blind placebo-
controlled studies in autism (however, dose in studies lower than we typically use). DMG is ranked #17 by parents on ARI list. Some children manifest good improvements with DMG, including speech.

CaveatCaveatOver 50% of what is done in medicine is “off-label”
Example of Study: A in Autism
Melatonin: 2 randomized, double-blind, placebo-controlled studies demonstrating improvement in the amount of time to fall asleep, number of nighttime awakenings, and length of sleep compared to both baseline and to placebo.

STEPS: Melatonin
Safety: two double-blind studies showing safety in children with autism
Tolerability: very little side effects Efficacy: Double-blind studies showing
improvements compared to placebo Price: less than $30 per month Simplicity: pill taken at bedtime
DOEs versus POEMs DOE: Disease Oriented Evidence
– Example: Cholesterol pill lowers my cholesterol by 50 points
– Example: Flecainide– Example: MB12 increases glutathione
POEM: Patient Oriented Evidence that Matters– Example: Cholesterol pill makes me live longer,
or prevents a heart attack or stroke– Example: MB12 improves speech
Ideal Treatment
Backed by Strength of Evidence: A Safe Tolerable Efficacious Cheap Simple, in-home treatment POEM: Outcome matters to child/parent
Treatment Options: Know Your Reason for Treatment
Based upon symptoms– e.g., inattention: pycnogenol, zinc,
carnitine, iron, omega-3 fatty acids
Based upon laboratory testing– e.g., oxidative stress: pycnogenol,
carnitine, CoQ10
Based upon probabilities– e.g., most children with autism have low
glutathione: MB12, folinic acid, pycnogenol
