Newborn screening by tandem mass spectrometry confirms the high prevalence of sickle cell disease among German newborns.

Sickle cell disease (SCD) is a severe inherited blood disorder associated with significant morbidity and mortality in early childhood. Since simple interventions are available to prevent early fatal courses, SCD is a target condition of several national newborn screening (NBS) programs worldwide, but not in Germany. Traditionally, the diagnosis of SCD is made by high-performance liquid chromatography (HPLC), isoelectric focusing (IEF), or capillary electrophoresis (CE), but globally, most NBS programs in place are based on tandem mass spectrometry (MS/MS).

Newborn screening for sickle cell disease: technical and legal aspects of a German pilot study with 38,220 participants.

Sickle cell disease (SCD) does not occur in the indigenous German population, but with the increasing number of immigrants from countries at high risk for hemoglobinopathies, the question emerges whether or not a newborn screening program (NBS) for SCD disease should be initiated in Germany anyhow. We have recently shown that in Berlin, a city with a very large immigrant population, the incidence of SCD is considerable, but our findings are insufficient to make a decision for the country as a whole. In this paper we will show that a large body of epidemiological data can be generated in a relatively short period of time, with a very high degree of precision and at relatively little expense--a result that might motivate other working groups to start such a pilot project locally.

Incidence of sickle cell disease in an unselected cohort of neonates born in Berlin, Germany.

Sickle cell disease (SCD) does not occur in the indigenous German population. However, with the increasing numbers of immigrants its prevalence is steadily rising. Nevertheless, robust epidemiological data is not available for Germany and, consequently, the German newborn screening (NBS) program does not include SCD.
