Critical bleeding in adults and children with immune thrombocytopenia: a multicenter cohort study

Critical bleeding in patients with immune thrombocytopenia (ITP) is a life-threatening hematologic emergency. This study aimed to describe the frequency, management, and outcomes of critical bleeds among adults and children with ITP. We conducted a retrospective cohort study of patients with ITP who presented to the emergency room with a platelet count <20 × 109/L across 7 centers in the United States and Canada between 2010 and 2019. Of 1226 patients (n = 296 adults; n = 930 children), 28 (2.3%) had critical bleeds (adults, n = 15 [median age, 68 years]; children, n = 13 [median age, 11 years]). Of patients with critical bleeds, 12 adults (80.0%) and 6 children (46.2%) had intracranial hemorrhage (ICH). For adults, the common interventions used to treat critical bleeds were platelet transfusions (n = 11 [73.3%]), corticosteroids (n = 10 [66.7%]), and IV immunoglobulin (n = 8 [53.3%]), and for children, common interventions were IV immunoglobulin (n = 10 [76.9%]), corticosteroids (n = 8 [61.5%]), platelet transfusions (n = 8 [61.5%]), thrombopoietin receptor agonists (n = 4 [30.8%]), and antifibrinolytic agents (n = 4 [30.8%]). For both adults and children, the most common treatment combination was corticosteroids, IV immunoglobulin, and platelet transfusion (n = 6 [40.0%] vs n = 6 [46.2%]). The median time from presentation to first treatment was 6.9 hours for adults and 3.5 hours for children. Overall, 9 patients (32.1%) with critical ITP bleeds died, including 7 adults (46.7%) and 2 children (15.4%). Critical bleeding in patients with ITP was rare but frequently fatal, especially among older adults with ICH and when treatments were delayed.

Abstract

Critical bleeding in patients with immune thrombocytopenia (ITP) is a life-threatening hematologic emergency. This study aimed to describe the frequency, management, and outcomes of critical bleeds among adults and children with ITP. We conducted a retrospective cohort study of patients with ITP who presented to the emergency room with a platelet count <20 × 109/L across 7 centers in the United States and Canada between 2010 and 2019. Of 1226 patients (n = 296 adults; n = 930 children), 28 (2.3%) had critical bleeds (adults, n = 15 [median age, 68 years]; children, n = 13 [median age, 11 years]). Of patients with critical bleeds, 12 adults (80.0%) and 6 children (46.2%) had intracranial hemorrhage (ICH). For adults, the common interventions used to treat critical bleeds were platelet transfusions (n = 11 [73.3%]), corticosteroids (n = 10 [66.7%]), and IV immunoglobulin (n = 8 [53.3%]), and for children, common interventions were IV immunoglobulin (n = 10 [76.9%]), corticosteroids (n = 8 [61.5%]), platelet transfusions (n = 8 [61.5%]), thrombopoietin receptor agonists (n = 4 [30.8%]), and antifibrinolytic agents (n = 4 [30.8%]). For both adults and children, the most common treatment combination was corticosteroids, IV immunoglobulin, and platelet transfusion (n = 6 [40.0%] vs n = 6 [46.2%]). The median time from presentation to first treatment was 6.9 hours for adults and 3.5 hours for children. Overall, 9 patients (32.1%) with critical ITP bleeds died, including 7 adults (46.7%) and 2 children (15.4%). Critical bleeding in patients with ITP was rare but frequently fatal, especially among older adults with ICH and when treatments were delayed.
