Antiphospholipid syndrome in Mexican children

Area of Science:

• Pediatric Rheumatology
• Immunology
• Hematology

Background:

• Pediatric antiphospholipid syndrome (APS) data is limited.
• Understanding pediatric APS is crucial for early diagnosis and management.
• Distinguishing primary APS from APS associated with SLE in children is important.

Purpose of the Study:

• To detail clinical and laboratory characteristics of pediatric APS.
• To identify complications in pediatric APS patients.
• To compare primary APS with SLE-associated APS in children.

Main Methods:

• Retrospective review of 32 pediatric patients at a Mexican children's hospital.
• Data collected included sociodemographics, clinical history, and immunological markers (anticardiolipin, anti-beta2 glycoprotein I, lupus anticoagulant, anti-dsDNA, antinuclear antibodies).
• Patients were categorized into primary APS, APS with SLE, or other conditions.

Main Results:

• The most frequent thrombotic events were small vessel thrombosis (44%), venous thrombosis (28%), and arterial thrombosis (25%).
• Common non-thrombotic manifestations included hematological (53%) and neurological disorders (22%).
• No significant differences were found in thrombosis site, non-thrombotic manifestations, or laboratory features between primary APS and APS associated with SLE.

Conclusions:

• Pediatric APS exhibits some differences compared to adult APS.
• No significant clinical or laboratory distinctions were observed between primary APS and SLE-associated APS in this pediatric cohort.
• Larger studies are needed to explore ethnic variations in Latin American pediatric APS.
