Episode notes
Initial ITP Workup And First-Line Therapy
- Request a peripheral smear early to rule out pseudothrombocytopenia and schistocytes before diagnosing ITP.
- Start steroids (dexamethasone 40 mg x4 days or prednisone 1 mg/kg with taper) and add IVIG for rapid platelet rise when counts are very low or bleeding is present.
Choosing Second-Line ITP Treatments
- For second-line ITP, prioritize TPO receptor agonists over rituximab per guidelines but individualize based on patient preference.
- Delay splenectomy until at least 12 months due to spontaneous remissions and surgical risks.
Avoid Reflex Platelet Transfusion
- Avoid routine platelet transfusions in ITP unless there is life‑threatening or active mucosal bleeding.
- Trust that platelets can be functional at very low counts and treat the immune process instead of reflexive transfusion.
