Transferrin in korean children with attention deficit hyperactivity disorder

Area of Science:

• Pediatric Hematology
• Neurodevelopmental Disorders

Background:

• Attention-Deficit/Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder.
• Iron metabolism plays a crucial role in brain development and function.

Purpose of the Study:

• To investigate the relationship between iron, ferritin, transferrin, total iron binding capacity (TIBC), hemoglobin, and red blood cell indices in children diagnosed with ADHD.
• To compare these hematological parameters between children with ADHD and age- and sex-matched controls.

Main Methods:

• A case-control study involving 48 children with ADHD and 48 controls (aged 6-8 years).
• ADHD diagnosis was confirmed using DSM-IV criteria and symptom severity was assessed with standardized rating scales.
• Hematological tests were performed to measure serum iron, ferritin, transferrin, TIBC, hemoglobin, MCV, MCH, and MCHC.

Main Results:

• No significant differences were observed in serum iron, ferritin, TIBC, or hemoglobin levels between the ADHD and control groups.
• A statistically significant difference was found in transferrin levels (p=0.011), with lower levels in the ADHD group.
• Mean Corpuscular Volume (MCV) (p=0.034) and Mean Corpuscular Hemoglobin (MCH) (p=0.034) also showed significant differences.

Conclusions:

• Lower serum transferrin levels may be associated with ADHD symptoms in children.
• The findings suggest a potential link between altered iron-related markers, specifically transferrin, and the pathophysiology of ADHD.
