Chokri Ben Lamine: ASH 2026 Adult Primary ITP Guidelines – Practice-Changing Update
Chokri Ben Lamine, Hematologist at King Faisal Specialist Hospital and Research Center, shared a post on X about a recent article by Adam Cuker et al., published in ASH Publications, adding:
“ASH 2026 Adult Primary ITP Guidelines – practice-changing update
1.Initial therapy
Consider either:
- Rituximab, corticosteroid with or without IVIG or Thrombopoietic agent, corticosteroid with or without IVIG rather than corticosteroids alone.
- Conditional recommendation; low-certainty evidence.
2.Diagnostic uncertainty?
- A brief corticosteroid course with or without IVIG for equal to or less than 2 weeks may confirm treatment responsiveness before combination therapy.
3.Steroid stewardship
- Dexamethasone 40 mg/day for 4 days, repeated for 1 – 3 cycles or prednisolone 0.5 – 2 mg/kg/day.
- Keep total corticosteroid exposure equal to or less than 6 weeks.
4.After first-line corticosteroid failure
- Thrombopoietic agent: strong recommendation, moderate-certainty evidence.
- Rituximab: conditional recommendation, low-certainty evidence.
- Rituximab may suit patients wishing to avoid chronic treatment.
5.If both are unsuitable
- Consider a BTK inhibitor, mycophenolate mofetil, or SYK inhibitor – guided by toxicity, access, cost and patient preference.
- Evidence remains very uncertain.
6.Splenectomy
- Delay equal to or more than 1 year from diagnosis when feasible.
- Vaccinate equal to or more than 2 weeks beforehand.
- Counsel regarding lifelong sepsis and thrombosis risks.
7.Switching thrombopoietic agents
- Reasonable for inadequate response, toxicity, comorbidities, adherence or preference.
- Avoid treatment gaps and monitor closely.
The modern goal is not simply a ‘normal’ platelet count – it is haemostasis, reduced bleeding, better quality of life and sustained treatment-free response.
MCQ: Preferred treatment after corticosteroid failure?
- Prolonged prednisone
- Thrombopoietic agent
- Immediate splenectomy
- Azathioprine
OSCE pearl: Discuss bleeding risk, treatment burden, thrombosis or infection, reproductive plans, cost and the patient’s preference before selecting therapy.”
