Limited Evidence for Anticoagulation Despite High VTE Risk in Sickle Cell Disease – RPTH
RPTH Journal shared on LinkedIn about a recent article by Mosaad Almegren et al, adding:
”What’s the best anticoagulant for venous thrombosis in sickle cell disease?
Patients with sickle cell disease (SCD) face a high risk of venous thromboembolism, yet evidence guiding anticoagulation choice remains limited.
A new RPTH study compared direct oral anticoagulants (DOACs) vs warfarin in adults with SCD experiencing their first VTE.
Here’s the key signal:
- Similar rates of recurrent thrombosis and major bleeding between DOACs and warfarin.
- Clinically relevant non-major bleeding was significantly lower with DOACs.
Some context from the cohort:
- 99 patients with SCD and VTE
- Pulmonary embolism was the most common event (~65%)
- Median follow-up ~44 months
- Most DOAC use involved rivaroxaban or apixaban
Translation:
For patients with SCD and thrombosis, DOACs may offer comparable protection with less bleeding burden.
Big questions for the field:
- Should DOACs become first-line therapy for VTE in SCD?
- How long should anticoagulation continue in this high-recurrence population?
- Do SCD-specific thrombosis mechanisms require tailored anticoagulation strategies?”
