Abstract

Globally, thalassemia is the most common hereditary hemoglobinopathy, and occurs in 4.4/10,000 live births. In the developing world, the majority of patients die before the age of 20 years. In Iraq, there is little data on the epidemiology and burden of thalassemia. The objectives of this study were to determine the prevalence, incidence, trend, and complications of thalassemia patients in Iraq. All thalassemia patients registered in the accessible 16 (of the 19) thalassemia centers in Iraq until December 31 2015, were included. Data were acquired from patients’ files and the centers’ registries. The total number of registered thalassemia patients was 11,165 representing 66.3% of all registered hereditary anemias in these centers. The prevalence of thalassemia had increased from 33.5/100,000 in 2010 to 37.1/100,000 in 2015, while the incidence rate had decreased from 72.4/100,000 live births to 34.6/100,000 live births between 2010 and 2015. β-Thalassemia major (β-TM) represented 73.9% of all types of thalassemia. About 66.0% of patients were under 15 years old; 78.8% were offspring of parents who were related, and 55.9% had at least one complication. Respectively, 13.5 and 0.4% of thalassemia patients were infected with hepatitis C virus (HCV) and hepatitis B virus (HBV) at some point in their lives. No patients were infected with the human immune deficiency virus (HIV). In conclusion, the prevalence of thalassemia in Iraq is slightly increasing in spite of decreasing incidence. Screening for carriers, and intensified premarital screening and counseling programs, coupled with strong legislation can help in further decreasing incidence rate.
