Association Between IL-10 and Serum Hepcidin in Patients with β-Thalassemia Major: A Case-Control Study Using...

Area of Science:

• Hematology
• Immunology
• Biochemistry

Background:

• Beta-thalassemia major is a chronic, transfusion-dependent disorder.
• It is characterized by severe iron overload and systemic inflammation.
• The interplay between inflammatory cytokines, iron chelation therapy, and hepcidin regulation is not fully understood.

Purpose of the Study:

• To investigate the associations between inflammatory and biochemical parameters and serum hepcidin in beta-thalassemia major.
• To explore the role of IL-10 and TNF-α in hepcidin regulation.
• To examine the influence of iron chelation therapy on these parameters.

Main Methods:

• A case-control study involving 100 patients with beta-thalassemia major and 40 healthy controls.
• Evaluation of hematological, biochemical parameters, inflammatory cytokines (IL-10, TNF-α), and serum hepcidin.
• Statistical analyses included nonparametric tests, Spearman's correlation, and bootstrapped multiple linear regression.

Main Results:

• Patients exhibited significantly higher levels of ferritin, liver enzymes, blood glucose, inflammatory cytokines, and hepcidin compared to controls.
• A strong positive correlation was observed between IL-10 and hepcidin (r=0.838, p<0.001).
• IL-10, but not ferritin, was significantly associated with serum hepcidin in the adjusted regression model (p<0.001).

Conclusions:

• Inflammatory activity, particularly IL-10, may be associated with hepcidin-related iron regulation in beta-thalassemia major.
• Serum ferritin is not an independent predictor of hepcidin levels in this context.
• Further longitudinal studies are required to elucidate the clinical significance of these findings.
