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

Area of Science:

• Genetics
• Hematology
• Public Health

Background:

• Sickle cell disease (SCD) is an inherited disorder causing chronic inflammation and end-organ damage.
• SCD leads to asplenia and increased risk of life-threatening infections in early childhood.
• Early diagnosis and management are crucial for reducing mortality and morbidity associated with SCD.

Purpose of the Study:

• To determine the incidence of sickle cell anemia and hemoglobinopathies in Murcia's neonatal population.
• To assess the benefits of newborn screening for SCD in facilitating earlier treatment.
• To offer genetic counseling to all identified carriers of SCD-related gene mutations.

Main Methods:

• Implementation of a newborn screening program for SCD in the region of Murcia starting March 2016.
• Monitoring the incidence of SCD and other structural hemoglobinopathies in newborns.
• Providing early medical attention to diagnosed SCD newborns and genetic counseling to carriers.

Main Results:

• The prevalence of SCD in Murcia is comparable to other Spanish regions, excluding Catalonia and Madrid.
• Newborns diagnosed with SCD received timely medical interventions.
• Genetic counseling was successfully provided to all identified carriers.

Conclusions:

• Newborn screening for SCD in Murcia enables early detection and management, improving outcomes.
• The screening program effectively reduces mortality and morbidity in affected infants.
• Genetic counseling plays a vital role in managing carriers and preventing future occurrences.
