The delay between clinical symptoms and initiation of pulmonary hypertension therapy was significantly longer in patients who subsequently died (mean±sd 33.5±23 days; median 30 days) than in survivors (mean±sd 7±3 days) (p<0.001).Conclusion Pulmonary hypertension is a severe complication of HSCT with an underestimated incidence and high mortality. Aggressive and timely up-front combination therapy allowed normalisation of pulmonary pressure and improved survival.Pulmonary hypertension is a rare and severe complication of haematopoietic stem cell transplantation in children, with a high mortality if misdiagnosed. Early diagnosis and treatment allow rapid clinical improvement with normalisation of PAP in most cases. http://bit.ly/2KXyhNN ER -
