Serum glycoconjugates in children with schizophrenia and conduct and adjustment disorders
Insights
Serum glycosaminoglycans and protein-bound carbohydrates differ in children with psychiatric disorders. Schizophrenia showed elevated levels, while conduct and adjustment disorders had specific carbohydrate changes, suggesting potential biomarkers.
Area of Science:
- Biochemistry
- Neuroscience
- Pediatrics
Background:
- Serum glycoproteins and glycosaminoglycans are crucial biological molecules.
- Previous research has explored biochemical markers in psychiatric disorders.
- Understanding these markers in children is vital for early diagnosis and intervention.
Purpose of the Study:
- To investigate race and sex-independent differences in serum glycoproteins and glycosaminoglycans.
- To compare these levels in normal children versus those with schizophrenia, conduct disorder, and adjustment disorder.
- To identify specific glycoconjugate alterations associated with pediatric psychiatric conditions.
Main Methods:
- Quantification of serum glycoproteins (protein-bound carbohydrates) and glycosaminoglycans (hexuronic acid).
- Analysis of samples from Black and Caucasian children, both healthy and diagnosed with psychiatric disorders.
- Confirmation of specific carbohydrate presence using chemical ionization-mass spectrometry.
Main Results:
- No race- or sex-related differences were observed in normal children.
- Serum glycosaminoglycans were significantly elevated in children with schizophrenia.
- Specific protein-bound carbohydrates (arabinose, galactosamine) showed differential elevations in conduct and adjustment disorders.
Conclusions:
- Serum glycoconjugate profiles differ across pediatric psychiatric diagnoses.
- Elevated glycosaminoglycans and specific carbohydrates may serve as potential biomarkers for schizophrenia and other disorders.
- Environmental factors and stress may influence these biochemical alterations.
Abstract:
The serum glycoproteins represented by the individual protein-bound carbohydrate components and glycosaminoglycans represented by the hexuronic acid contents were determined in the sera of black and Caucasian normal children and children with diagnoses of schizophrenia, conduct disorder, and adjustment disorder. There were no race-related or sex-related differences in glycoproteins and glycosaminoglycans in the sera of normal children. Although the serum glycosaminogltents were determined in the sera of black and Caucasian normal children and children with diagnoses of schizophrenia, conduct disorder, and adjustment disorder. There were no race-related or sex-related differences in glycoproteins and glycosaminoglycans in the sera of normal children. Although the serum glycosaminogltents were determined in the sera of black and Caucasian normal children and children with diagnoses of schizophrenia, conduct disorder, and adjustment disorder. There were no race-related or sex-related differences in glycoproteins and glycosaminoglycans in the sera of normal children. Although the serum glycosaminoglycans were significantly elevated in children with a diagnosis of schizophrenia, the levels were in normal range in children with conduct and adjustment disorders. All of the protein-bound carbohydrates were elevated in schizophrenic children. However, only arabinose and galactosamine were significantly elevated in children with a diagnosis of conduct disorder, while only galactosamine was elevated in children with adjustment disorder. The presence of arabinose in serum glycoprotein was confirmed by chemical ionization-mass spectrometry. The possible causes of the differential elevation of the glycoconjugates in psychiatric disorders in relation to the effect of stress and environment are discussed.
