|August 1, 1986
Summary
Elevated blood neuroanalytes and distinct peptide patterns in autistic children suggest potential biomarkers for early autism diagnosis. Further research is needed to confirm these findings for infantile autism detection.
Area of Science:
- Biochemistry
- Neuroscience
- Pediatrics
Background:
- Early diagnosis of infantile autism is critical.
- Biochemical markers are essential for identifying potential diagnostic indicators.
Purpose of the Study:
- To investigate differences in blood neuroanalyte concentrations and peptide patterns between autistic subjects and normal controls.
- To identify potential biochemical markers for the early diagnosis of infantile autism.
Main Methods:
- Measured blood concentrations of epinephrine, norepinephrine, dopamine, and serotonin.
- Analyzed peptide patterns using Sephadex G-25 chromatography.
- Identified peptides using High-Performance Liquid Chromatography (HPLC).
Main Results:
- Autistic subjects showed elevated blood concentrations of epinephrine, norepinephrine, dopamine, and serotonin compared to controls.
- Distinct peptide patterns (Sephadex G-25 peaks I-V) were observed in autistic subjects.
- Methionine-enkephalin was tentatively identified in fraction I of autistic subjects; a specific HPLC peak (7.6 min) was found in fraction V of autistic subjects but not in controls.
Conclusions:
- Blood neuroanalyte levels and specific peptide profiles may serve as potential biomarkers for infantile autism.
- Further validation is required to establish these biochemical markers for clinical use in early autism diagnosis.
