title: Report on Ten Years' Experience of Premarital Hemoglobinopathy Screening at a Center in Antalya, Southern Turkey.
abstract: Thalassemia and hemoglobinopathies are a major public health problem in Turkey. Hemoglobinopathy prevention programs (HPPs) were started in 33 provinces situated in Thrace, Marmara, Aegean, Mediterranean and South Eastern regions of Turkey in 2003. A premarital hemoglobinopathy test is mandatory and free of charge in this program. According to the Ministry of Health reports, 46 first level hemoglobinopathy diagnostic centers were established for premarital tests. Within the last 10 years, approximately 79.0% of married individuals per year were screened by the centers. While the percentage of premarital screening tests was 30.0% of all couples in 2003, it reached 86.0% in 2013. The number of newborn with thalassemia and hemoglobinopathies were 272 in 2002 and dropped to 25 in 2013. There has been a 90.0% reduction in affected births. Our hemoglobinopathy diagnostic center was established in 2003 and licensed by the Ministry of Health in 2004. We studied a total of 89,981 blood samples from premarital tests for 10 years and the incidence of β- and α-thalassemia (β- and α-thal) trait was found to be 6.57 and 3.56%, respectively. The distribution of the most common abnormal hemoglobins (Hbs) was: Hb S (HBB: c.20A > T) (0.31%), Hb D-Los Angeles (HBB: c.364G > C) (0.15%), Hb G-Coushatta (HBB: c.68A > C) (0.06%) and Hb E (HBB: c.79G > A) (0.02%). A total of 60 couples, both carrying β-thal trait, were directed to the prenatal diagnosis (PND) center in 10 years. The premarital hemoglobinopathy screening program is running successfully at our center and other centers in Turkey.
