Circulating High Mobility Group Box-1 Does Not Predict Pulmonary Arterial Hypertension in Children with Congenital Heart Disease: A Prospective Cohort Study.
Pulmonary arterial hypertension (PAH) is a devastating complication of pediatric congenital heart disease (CHD). A recent study has identified the protein high mobility group box-1 (HMGB1) as a diagnostic tool in adults with CHD-associated PAH. HMGB1 levels in adults with CHD-associated PAH correlated with mean pulmonary artery pressure and pulmonary vascular resistance, and HGMB1 levels fell in response to sildenafil therapy. We wanted to assess if HGMB1 was a biomarker of pediatric CHD-PAH. ⋯ Unlike in adults, HGMB1 is not a biomarker of PAH in pediatric CHD. Further work will continue to explore for biomarkers for this high-risk population.
