Summary
Severe factor X deficiency in an infant caused severe bleeding and was temporarily managed with factor X concentrate. Despite treatment, the infant tragically died from an intracerebral hemorrhage at four months old.
Area of Science:
- Hematology
- Pediatric Medicine
- Genetics
Background:
- Congenital factor X deficiency is a rare inherited bleeding disorder.
- Early diagnosis and management are crucial for patients with severe factor X deficiency.
Observation:
- A neonate presented with severe bleeding, including from heel prick sites, bruising, and hematoma, indicative of a coagulation disorder.
- The infant exhibited a severe deficiency of factor X, a critical clotting protein.
Findings:
- Infusion of human factors II, IX, and X concentrate temporarily controlled bleeding.
- The infused factor X had a short half-life of only 18 hours.
- Despite prophylactic factor X concentrate infusions, the infant suffered a fatal intracerebral hemorrhage at four months of age.
Implications:
- This case highlights the challenges in managing severe factor X deficiency, particularly in neonates.
- The short half-life of factor X concentrate necessitates frequent infusions, increasing treatment complexity.
- Further research into novel therapeutic strategies for factor X deficiency is warranted to improve patient outcomes.
