[Borderline neuropsychiatric disorders in purine metabolism disorders in children]
Insights
Children with neuro-arthritic diathesis often show family history of purine metabolism disorders. These include hyperuricemia (HU) and hyperuricuria (HUK), linked to neuropsychic disturbances.
Area of Science:
- Pediatric Neurology
- Metabolic Disorders
- Clinical Genetics
Context:
- Investigates the link between purine metabolism disorders and neuropsychic disturbances in children.
- Focuses on children diagnosed with neuro-arthritic diathesis.
- Examines family history of primary purine metabolism disorders.
Purpose:
- To identify the prevalence of purine metabolism abnormalities in children with neuro-arthritic diathesis.
- To correlate specific purine metabolism parameters (hyperuricemia and hyperuricuria) with neuropsychic symptoms.
- To differentiate clinical presentations based on the severity of metabolic and neurological findings.
Summary:
- A study of 410 children revealed 150 with a family history of primary purine metabolism disorders (hyperuricemia/hyperuricuria) and neuropsychic disturbances.
- Most affected children (122/150) exhibited neurotic-level reactivity disorders (neuroses, neurotic reactions) alongside moderate hyperuricemia and hyperuricuria.
- A subset (28/150) showed behavioral abnormalities linked to residual-organic cerebral insufficiency and significant purine metabolism deviations.
Impact:
- Highlights the potential role of inherited purine metabolism defects in pediatric neuropsychic conditions.
- Suggests the need for metabolic screening in children presenting with specific neurological and behavioral issues.
- Provides insights into the clinical heterogeneity of neuro-arthritic diathesis associated with metabolic dysfunction.
Abstract:
A thorough examination of 410 children with the preliminary diagnosis of neuro-arthritic diathesis revealed a family history of primary disorders of purine metabolism with hyperuricemia (HU) and hyperuricuria (HUK) in combination with borderline neuropsychic disturbances in 150 children. Most of the children (122 of the 150) presented disorders of the neurotic level of reactivity according to the type of systemic and monosystemic neuroses and neurotic reactions in the presence of moderate HU and HUK. The clinical picture in children with the signs of residual-organic cerebral insufficiency (28 of the 150) was predominantly characterized by behavioural abnormalities in conjunction with significant deviations on the part of purine metabolism parameters.
