[Effectiveness of the screening programme for galactosemia. New strategy in Poland].
Galactosemia is an autosomal recessive disease related to deficiency of one of three different enzymes involved in the metabolism of galactose: galactokinase (GALK), galactoso-J-phosphate uridyltransferase (GALT) or UDP-galactose-4-epimerase (GALE). Classic galactosemia is due to GALT deficiency and is the most common. Longitudinal studies have shown that in spite of early diagnosis and early treatment of children with galactosemia detected in the mass screening programme, the results are poor and mental retardation as well as other complications are of similar severity as in children diagnosed clinically without screening. In many investigations it was also proved that some impairments developed already in the prenatal period. Therefore, many countries among them also Poland, stopped mass screening for galactosemia. At present, in Poland the procedure strategy in galactosemic children and their families include: diagnosis of new cases on the basis of clinical symptoms, selective screening in high-risk families, prophylactic lactose-free diet for mothers during pregnancy. Such management can help to prevent clinical manifestations in newborns and prevent death in the early period of life.
