Abstract: Background: ‘Beta thalassemia is inherited hemoglobin disorder resulting in chronic hemolytic anemia that requires lifelong transfusion therapy’. ‘Repeated blood transfusions and RBCs hemolysis are the main causes of iron overload’, which in addition to immune abnormalities, are common predisposing factors to infections in patients with thalassemia.

The Aim of this Work: The aim of this work was to study immune status including T lymphocyte subsets and serum immunoglobulin levels ‘in children with beta- thalassemia in correlation with iron overload’.

Patients and Methods: The present ‘study was conducted on 40 children with beta thalassemia major under follow up at Hematology Unit, Pediatric Department, Tanta University’ ‘including 24 males and 16 females with mean’ age value of 9. 22 ± 3.9 years and 20 ‘healthy children of matched age and sex as a control group’. All children included in the study were subjected to; ‘complete blood count, Hb electrophoresis, serum iron status’, T cell subsets including CD3, CD4 and CD8 and serum immunoglobulin levels including IgM, IgA and IgG.

Results: ‘Pallor and jaundice were the most common presenting’ clinical manifestations. Infective episodes ‘were significantly higher in patients’ compared with controls. There were significantly lower Hb, MCV and MCH levels and significantly higher WBCs and platelets counts, reticulocytes and lymphocytes percentage in patients than controls and no significant differences in MCHC between patients and controls. Serum ferritin and iron were ‘significantly higher but TIBC was significantly lower in’ patients than controls. CD3, CD4 and IgM were significantly lower but CD8, IgG, and IgA ‘were significantly higher in patients than controls’ with negative correlation between CD3, CD4, IgM and ferritin and positive correlation between CD8, IgG, IgA and ferritin.

Conclusion: Iron overload can affect humeral and cell mediated immunity in patients with beta thalassemia with reduction of IgM, CD3 and CD4 and elevation of CD8, IgG, and IgA.

Recommendations: Regular follow up of patients with beta thalassemia for detection of iron overload as it affects humeral and cell mediated immunity.
