Clin Exp Pediatr. 2025;68(10):819-830. Published online July 8, 2025

Question: What are the biochemical and clinical correlates of hyperhomocysteinemia in pediatric β-thalassemia, and how does it relate to vitamin status, oxidative stress, and splenectomy?
Finding: Most pediatric β-thalassemia patients exhibited severe hyperhomocysteinemia, which was strongly associated with folate and B₁₂ deficiencies and influenced oxidative stress patterns, particularly in splenectomized individuals.
Meaning: These findings suggest that routine monitoring and correction of B-vitamin deficiencies may mitigate hyperhomocysteinemia-related risks in pediatric thalassemia.
