Screening for abnormal hemoglobins in the middle east: new data on hemoglobin S and the presence of hemoglobin C in Saudi Arabia.

48 of 391 apparently healthy adult Saudi males had an AS hemoglobin pattern on electrophoresis, four subjects had an S pattern, and two subjects AC. A dithionite screening test lacked sensitivity and specificity in detecting hemoglobin S under the conditions of this study. A sickle cell trait frequency of 0.123 evidenced by hemoglobin electrophoresis correlates closely with previous studies of hemoglobinopathies in Saudi Arabs. The presence of four subjects with sickle cell disease in the study group provides further evidence of the "benign" nature of sickle cell disease in Saudi Arabia.

Newborn diagnosis of abnormal hemoglobins from a large municipal hospital in Los Angeles.

Cord blood samples from 29,611 infants born in Los Angeles over a 71/2 year period were examined for hemoglobinopathies. Among 4,134 Black newborns, the frequency of sickle cell anemia (SS) was 0.3 per cent, of sickle cell trait (AS) 8 per cent, and of Hb-C trait (AC) 2 per cent. Of 17,781 Spanish surnamed (Mexican) newborns, 0.5 per cent had sickle cell trait, and 0.1 per cent had Hb-C trait. Of the 5,541 Caucasian infants, 0.7 per cent had sickle cell trait, and 0.15 per cent had Hb-C trait. Twenty-three Black children with major hemoglobinopathies included 16 with sickle cell anemia, two with hemoglobin C disease (CC), and five with SC disease.
