Advances in neonatal screening for primary immune deficiencies

Area of Science:

• Immunology
• Pediatrics
• Genetics

Background:

• Primary immunodeficiencies (PID) are congenital disorders impairing immune competence, leading to severe infections.
• Infants with PID often experience repetitive, drug-resistant infections, with over 200 identified cases and increasing incidence.
• The clinical severity of PID is extensive, exacerbated by a lack of efficient diagnostic and management strategies.

Purpose of the Study:

• To review emerging diagnostic assays and conceptual frameworks for newborn screening of severe primary immunodeficiencies.
• To highlight advancements in neonatal screening for PID to improve early detection and intervention.

Main Methods:

• Literature review of recent advancements in newborn screening for primary immunodeficiencies.
• Analysis of novel assays and screening concepts for severe PID.

Main Results:

• Current screening methods for PID are insufficient to address the increasing incidence and severity of these disorders.
• New assays and screening strategies are under development to enhance the detection of severe PID in neonates.

Conclusions:

• Improved newborn screening is crucial for timely diagnosis and management of severe primary immunodeficiencies.
• The development and implementation of advanced screening technologies hold promise for reducing the burden of PID in infants.
