Background: β Thalassaemia major is one of the chronic hemolytic anemias resulting from defect in β globin chain. It requires frequent blood transfusion plus other treatment modalities. These treatment modalities may be associated with certain immunologic modulations. Objective: To assess various immunological parameters in β thalassemic children under different treatment modalities. Subjects and Methods: Forty-eight children were enrolled and classified into four groups. Twelve β thalassemic patients treated only with blood transfusion (group I). Twelve patients treated with transfusion and iron chelation (group II). Twelve patients treated with transfusion, iron chelation and subjected to splenectomy (group III). Group IV involved twelve healthy age and sex matched children. CBC plus serum levels of ferritin, were measured along with detection of CD3, CD4 and CD8 percentages. Results: Significant statistical differences regarding CD3, CD4 and CD8 T lymphocytes percentages within thalassemic groups when compared to each other’s and to healthy controls except for CD3 T lymphocytes in group II versus III. Splenectomized patients had higher significant levels regarding serum ferritin (p=0.02), CD4 (p=0.001), CD8 (p=0.001) and CD3 (p=0.001) compared to non splenectomized ones. Conclusion: Immune modulation occurs in thalassemic patients with regional specific variations. This may also be related to the difference in treatment modalities.
