Splenectomy changes the pattern of cytokine production in beta-thalassemic patients.

A major cause of morbidity and mortality in beta-thalassemic patients is infections, assumed to be the result of immunological changes. To determine the possible defect, we investigated the cytokine productions by blood cells of beta-thalassemic patients using in-vivo and in-vitro methods. Heparinized blood samples collected aseptically from 22 beta-thalassemic children aged 10-12yrs (half of them were splenectomized).
