Episode 015: Heme/Onc Emergencies, Pt. 4: Immune thrombocytopenic purpura

Emergencies happen in hematology and oncology. This is a fact. But how do we manage these emergencies? Look no further. In this episode, we talk all about our first hematologic emergency: immune thrombocytopenic purpura (ITP). Immune thrombocytopenic purpura (ITP): Be sure to check out episode 009 on thrombocytopenia for a general approach and differential! Specific instances where there may be close to undetectable platelet count: * Lab artifact (clumping) * Very severe DIC * Thrombotic thrombocytopenic purpura - though usually higher platelets in these cases * Heparin induced thrombocytopenia (in very severe cases) - though usually higher platelets in these cases * ITP ITP: Diagnosis of exclusion How to confirm it is ITP? * Post-transfusion CBC - a repeat CBC 30-60 mins after a platelet transfusion. In ITP, the platelet count will likely not budge. (Not perfect test!) * Immature platelet fraction (if available) - this will be elevated if mature platelets are being destroyed. (Again - not a perfect test) Treatment in acute cases: IVIG 1g/kg daily x2 days + Dexamethasone 40mg daily x4 days Reference: https://ashpublications.org/blood/article/106/7/2244/21649/How-I-treat-idiopathic-thrombocytopenic-purpura - Great How I Treat article from Blood Please visit our website (TheFellowOnCall.com) for more information Twitter: @TheFellowOnCall Instagram: @TheFellowOnCall Listen in on: Apple Podcast, Spotify, and Google Podcast
