A Newborn Screening Program for Sickle Cell Disease in Murcia (Spain).

Sickle cell disease (SCD) is an inherited autosomal recessive hemoglobin disorder caused by the presence of hemoglobin S, a mutant abnormal hemoglobin caused by a nucleotide change in codon 6 of the β-globin chain gene. SCD involves a chronic inflammatory state, exacerbated during vaso-occlusive crises, which leads to end-organ damage that occurs throughout the lifespan. SCD is associated with premature mortality in the first years of life.

Phenotypic characterization of a pediatric cohort with cystinuria and usefulness of newborn screening.

Background: Cystinuria is an inherited metabolic disease involving the defective transport of cystine and the dibasic amino acids in the renal proximal tubules that causes the formation of stones in the urinary system. In our regional child health program, cystinuria is included in newborn metabolic screening. Our objectives are the phenotypic characterization of our cystinuric pediatric cohort and to present our experience in neonatal cystinuria screening.

[Beginnings, evolution and current situation of the Newborn Screening Programs in Spain.].

Newborn Screening Programs (NSP) in Spain were born in the city of Granada in 1968. Till the 1980s, they were developed around the so-called "National Plan for Preventing Subnormality", covering up to 30% of the Spanish newborns. From 1982, when the health system management was transferred to the different autonomous regions, the NSP began to expand, and the bases to transform them into an organized and multidisciplinary activity, integrated and coordinated from the National Health System were settled.
