Summary
Selective screening for galactosemia in newborns, focusing on symptomatic infants, effectively identifies most severe cases. This approach may be as timely as universal screening programs for early diagnosis and intervention.
Area of Science:
- Biochemistry
- Genetics
- Pediatrics
Background:
- Galactosemia screening lacks universal guidelines.
- Current practices involve selective screening for classical galactosemia in infants under two weeks or with suggestive symptoms.
Purpose of the Study:
- To evaluate the effectiveness of selective screening for classical galactosemia.
- To compare selective screening with population-based screening for early detection.
Main Methods:
- Retrospective analysis of screening data.
- Conducted selective screening for classical galactosemia in infants under 2 weeks of age and those presenting with symptoms.
Main Results:
- Eighteen cases of galactosemia were diagnosed out of 25,099 tests.
- Seventeen of the diagnosed cases were symptomatic at the time of detection, highlighting the importance of clinical presentation.
Conclusions:
- Improved clinical vigilance combined with selective screening can identify most infants with severe galactosemia.
- This strategy may achieve early diagnosis comparable to population-based screening programs.
