Doppler-defined pulmonary hypertension and the risk of death in children with sickle cell disease followed for a mean of three years.
Pulmonary hypertension (PH) is associated with increased mortality in adults with sickle cell disease (SCD), but its prognostic significance in children is unknown. Eighty-eight children with SCD were followed after echocardiographic screening for PH. After a mean follow-up of 3 years, all 18 subjects with PH were alive. In our children, as in adults with SCD, PH was associated with increased haemolysis. In contrast, our subjects with PH did not have overt systemic disease observed in adults. PH may be a manifestation of progressive organ damage from chronic haemolysis and systemic vasculopathy that ultimately leads to early death in adulthood.
