ABSTRACT
Thalassemia intermedia empasses a mild clinical and biological spectrum. The aim is to report the clinical and biological features and treatment of this disease. It is a retrospective study about 36 thalassemia intermedia patients [17 males, 19 females]. Epidemiological, haematological aspects and treatment were reported. The diagnosis was carried out at a relatively old age 15 years [1-72].The thalassemia intermedia was characterized by mild facial deformities, splenomegaly and moderate anemia [Hb=9.1 g/dl]. The mean serum ferritin was 518 ng/ml [25-1800].Three phenotypes are caracterised: heterozygosis beta thalassemia, beta° thalassemia and beta° thalassemia. Clinical complications were hypersplenism, extra medullary hematopoiesis, leg ulcers, thrombosis and pulmonary hypertension. Treatment was based on occasionally transfusion and splenectomy on event of hypersplenious [47%]. Evolution of this disease was generally good with a long lifespan at 31 years [6-83]. Thalassemia intermedia is well tolerated. Transfusions and splenectomy were indicated in case of hypersplenious
