Keywords:

Introduction: The birth of people with SS and SC hemoglobine justified the creation of a prevention program in Cuba which includes the antenatal diagnosis of these hemoglobinopathies.
Objective: To show the impact of the antenatal diagnosis in the incidence of sickle-cell anemia and of the composed heterocigotic disease SC.
Methods: A descriptive restrospective and cross-sectional study was carried out in the Provincial Department of the Teaching Southern Pediatric Hospital Antonio María Béguez César in Santiago de Cuba, which included three decades and a sexennium (from 1984 to 2019), of the 713 fetuses and children in whom sickell-cell anemia was diagnosed. To establish the prenatal diagnosis, hemoglobine electrophoresis to all pregnant women, —During the first years with Havana equipment and from 2012 on, with the technology Hydrasys—.
Results: From the total of diagnosed cases, pregnancy was interrupted in 44,3 %, with a significant increase of aborptions provoked due to this cause with the passing of years: 23.7 % in the first decenium, 46.1 in the second and 68.1 % in the third, while in the period 2014-2019 it was 59.3 %. Due to this, the births of sick children to from 76.3 % at the beggining of the study to 53.9 and 31.9 respectively, and finally to 40.7 % in the sexenium 2014-2019.
Conclusions: The prenatal diagnosis of sickel-cell anemia SS and SC constitutes the key stone for the prevention of these hemoglobinopathies.
