Abstract: (5755 Views)
The aim of this study was to evaluate the immune system and lymphocyte
function in 41 Iranian β-thalassemic patients and 50 controls, ages ranging
from 2 to 18 years. The patients consisted of 20 splenectomized and 21
non-splenectomized patients. They were treated with Desferal, and had received
repeated blood transfusion. Laboratory investigations included measurement
of total T lymphocytes, active T lymphocytes, B-Iymphocytes and
function of lymphocytes treated with PHA. In this study we observed a significant
reduction of active T lymphocytes and total T lymphocytes in the
patient group compared to controls (p<0.005 & p<0.001), but there was no
significant difference between splenectomized and non-splenectomized patients.
Also in both groups, lymphocyte function was reduced against PHA
(phytohemagglutinin) compared with the controls, and the numbers of B cells
were increased. These results lead to the conclusion that the deficient immune
system in β-thalassemia causes infectious diseases, which finally leads
to death. Therefore, stimulation of the immune system as well as clinical treatment
may prevent infectious disease in patients with β- thalassemia.
