[Changes of iron metabolism indices in children with various genotypes of thalassema]

Area of Science:

• Hematology
• Pediatric Medicine
• Clinical Chemistry

Context:

• Thalassemia is a group of inherited blood disorders.
• Accurate diagnosis and monitoring of iron metabolism are crucial in managing thalassemia.
• Distinguishing between different types of thalassemia and iron deficiency anemia is essential for appropriate treatment.

Purpose:

• To evaluate the diagnostic and monitoring value of serum iron (SI), total iron-binding capacity (TIBC), and transferrin (Tf) in children with various types of thalassemia and iron deficiency anemia (IDA).
• To compare the effectiveness of SI, TIBC, and Tf in assessing iron loading in pediatric thalassemia patients.

Summary:

• This study analyzed SI, TIBC, and Tf levels in children with silent alpha-thalassemia, standard alpha-thalassemia, HbH disease, beta-thalassemia (beta+ and beta0), and IDA, alongside healthy controls.
• Results indicated that increased SI and decreased TIBC are significant indicators for beta-0 thalassemia, outperforming Tf in monitoring iron loading.
• Transferrin levels were notably lower in silent and standard alpha-thalassemia compared to healthy children, while HbH disease showed lower TIBC and Tf.

Impact:

• The findings suggest that SI and TIBC are more effective than Tf for monitoring iron overload in pediatric thalassemia.
• These indices can aid in the specific diagnosis of beta-0 thalassemia in children presenting with anemia.
• This research contributes to improved diagnostic strategies and patient management for thalassemia.
