Significant prevalence of sickle cell disease in Southwest Germany: results from a birth cohort study indicate the necessity for newborn screening.
Children with sickle cell disease (SCD) benefit from newborn screening, because life-threatening complications can be prevented by pre-symptomatic diagnosis. In Germany, the immigration of people from endemic countries is steadily growing. Comprehensive data about the epidemiology and prevalence of SCD in Germany are however lacking, and SCD is not included in the national newborn screening program. ⋯ The novel molecular method and strategy for newborn screening for SCD presented here compares favorably in terms of sensitivity (1.0 for homozygous HbS, 0.996 for heterozygous HbS), specificity (0.996), practicability, and costs with conventional biochemical screening. Our results demonstrate a significant prevalence of SCD of approximately 1:12,000 in an unselected urban and rural population in Southwest Germany. Together with previously published even higher results from exclusively urban populations in Berlin and Hamburg, our data provide the basis for the decision on a newborn screening program for SCD in Germany.
