[Treatment of homozygote beta thalassemia in Algiers. A 5-year follow-up of 66 patients]. / Traitement des beta-thalassémies homozygotes à Alger. Suivi de 66 malades sur 5 ans.

During the years 1982-1987, 66 patients with homozygous beta-thalassaemia were treated at the blood transfusion centre of Algiers. The patients, aged from 1 to 23 years in 1982, came from 48 families, 30 of which were issued from consanguinous unions. The patients fell into three groups according to the early institution and quality of treatment (blood transfusions, antibiotic therapy, desferrioxamine given when available). The beneficial clinical effects observed (satisfactory growth and development, reduction of splenomegaly and hypersplenism, attenuation of craniofacial malformations, performance at school) seemed to be directly related to the mean haemoglobin level prior to transfusion and to the early institution of treatment. Four patients died of anaemia and haemochromatosis. The incidence of viral contamination was 27.5 per cent for the hepatitis B virus and nil for the human immunodeficiency virus.
