Characterization of acquired anemia in children by iron metabolism parameters

Area of Science:

• Pediatric Hematology
• Iron Metabolism
• Biochemistry

Background:

• Inflammatory conditions are linked to anemia of chronic disease and acute infections.
• Hepcidin plays a crucial role in iron metabolism during inflammation.
• Differentiating anemia causes in children requires understanding specific biochemical markers.

Purpose of the Study:

• To investigate the biochemical characteristics of anemia in pediatric patients with different underlying causes.
• To assess the role of hepcidin and other biomarkers in distinguishing between various types of anemia in children.
• To establish etiology-specific biochemical profiles for improved anemia diagnosis and management in pediatric populations.

Main Methods:

• A cohort of 38 pediatric patients with anemia was studied, divided into four groups: inflammatory bowel disease (IBD), iron deficiency anemia (IDA), celiac disease (CD), and acute infection (AI).
• Comprehensive laboratory analyses were performed at diagnosis, including complete blood count, iron studies (serum iron, transferrin, ferritin), vitamin B12, folic acid, C-reactive protein (CRP), erythropoietin, hepcidin, and soluble transferrin receptor (sTfR).

Main Results:

• Iron deficiency anemia patients exhibited the lowest hemoglobin, MCV, iron, ferritin, and hepcidin levels, alongside elevated transferrin and sTfR.
• Patients with acute infection presented with the highest ferritin, CRP, and hepcidin values.
• Hepcidin levels demonstrated strong positive correlations with both CRP (r=0.83) and ferritin (r=0.85).

Conclusions:

• Distinct biochemical profiles are associated with different causes of anemia in children.
• Hepcidin levels, in conjunction with other biomarkers like CRP and ferritin, are valuable in differentiating anemia etiologies.
• Identifying these specific profiles can guide physicians in the accurate diagnosis and targeted treatment of pediatric anemia.
