Implication

Comparative study demonstrates that thromboelastography identifies rare bleeding disorders in children, suggesting its utility as an effective screening tool to predict bleeding severity.

Key Points

To assess the diagnostic value of thromboelastography (TEG) as an adjunct screening tool for rare bleeding disorders (RBDs) and correlate clot kinetics with clinical bleeding phenotypes.
Compared whole-blood TEG parameters and clot kinetics between 26 pediatric patients with RBDs and 30 healthy controls.
Categorized patients into bleeding phenotype severities (asymptomatic, mild, moderate, and severe) to correlate with TEG clot kinetic metrics.
Clot kinetics were abnormal in all 26 RBD patients versus 0 of 30 controls, with mean maximum rate of thrombus generation (MRTG) significantly lower in RBDs (6.0 vs. 15.4 mm min⁻¹, P < 0.0001).
MRTG significantly tracked bleeding phenotype severity, averaging 7.7 mm min⁻¹ in mildly symptomatic, 5.5 in moderately symptomatic, and 4.1 in severely symptomatic patients (P < 0.0001).
Dysfibrinogenaemia and platelet disorders showed marked decreases in maximum amplitude and low MRTG, whereas factor XIII and PAI deficiencies demonstrated increased fibrinolysis alongside low MRTG values.
