Our “Alveolar Hemorrhage Analysis” Paper has been published in “Biology of Blood and Marrow Transplantation”

Our new paper, in collaboration with  Dr Elinoff and Dr Suffredini was recently published in Biology of Blood and Marrow Transplantation (Impact Factor: 3.404).

Abstract:
The mortality rate of alveolar hemorrhage following allogeneic hematopoietic stem cell transplantation is greater than 60% with supportive care and high dose steroids. We performed a retrospective cohort analysis to assess the benefits and risks of rFVIIa as a therapeutic adjunct for alveolar hemorrhage. From 2005 to 2012, 57 episodes of alveolar hemorrhage occurred in 37 patients. Fourteen episodes (in 14 patients) were treated with steroids alone and 43 episodes (in 23 patients) were treated with steroids and rFVIIa. The median (interquartile range) steroid dose was 1.9 mg/kg/d (0.8 – 3.5; methylprednisolone equivalents) and did not differ statistically between the two groups. The median rFVIIa dose was 41 μg/kg (39-62) and a median of 3 doses (2-17) was administered per episode. Concurrent infection was diagnosed in 65% of the episodes. Patients had moderately severe hypoxia (median PaO2/FiO2, 193 [141-262]); 72% required mechanical ventilation and 42% survived to extubation. The addition of rFVIIa did not alter time to resolution of alveolar hemorrhage (p = 0.50), duration of mechanical ventilation (p = 0.89), duration of oxygen supplementation (p = 0.55), or hospital mortality (p = 0.27). Four possible thrombotic events (9% of 43 episodes) occurred with rFVIIa. rFVIIa when used in combination with corticosteroids did not confer clear clinical advantages compared to corticosteroids alone. In patients with AH following hematopoietic stem cell transplant, clinical factors (i.e. worsening infection, multiple organ failure or recrudescence of primary disease) may be more important than the benefit of enhanced hemostasis from rFVIIa.
