Abstract
To determine the prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) markers among Bahraini children with hereditary haemolytic anaemias, a cross-sectional study was conducted at the paediatric outpatient clinic of Sulimaniya Medical Center in the State of Bahrain. A total of 242 patients with hereditary haemolytic anaemias were enrolled in the study: 171 (71%) with sickle cell syndromes, 59 (24%) with beta thalassaemia major and 12 (5%) with alpha thalassaemia. Among the 191 multi-transfused patients, 39 (20.5%) had one or more markers for HBV, 78 (40%) were seropositive for HCV antibody, and three (1.6%) were seropositive for HIV antibody. In contrast, none of the 51 non-transfusion group was seropositive for HBV and HIV antibodies but one patient was seropositive for HCV antibody. HBV, HCV and HIV infections therefore remain a major hazard for children with hereditary haemolytic anaemias, despite blood donor screening. More refined and sensitive tests which would detect infection in all stages of the disease are required. Hepatitis B vaccine should be given to all children with hereditary haemolytic anaemias.
