Serum Immunoglobulin Levels in Splenectomized and Non-Splenectomized Patients with Major Beta-Thalassemia

Objective: thalassemia is a common disease in many countries, in which several complications such as infections can occur. although aberration in the function of the immune system could be a reason for such complication, a little is known about the status of humoral immune system in major beta thalassemia. in this study we measured serum immunoglobulins level in a group of patients with major beta thalassemia. methods: ninety nine patients with major beta thalassemia were enrolled in this study divided into two groups of splenctomized and not splenctomized patients. serum igg, igm and iga levels of these patients were measured and analyzed. findings: serum mean levels of igg and igm in patients of all ages in both groups were normal. the mean serum iga level in the group of not splenectomized patients aged less than five years as well as in the splenectomized patients aged more than twenty years was increased. however, it was normal in other age groups. conclusion: although this study could not show any defect in the humoral immune system, evaluation of immunoglobulins could be useful to understand the relmarkable high rate of infection in the patients with major beta thalassemia
