2022, Hematology, Transfusion and Cell TherapyCitation Excerpt :In 10 children with SCA and previous stroke, when pRBC transfusions to maintain HbS < 20% were stopped after 1 or 2 years of treatment, the recurrence rate was similar to that found in non-transfused patients with previous stroke. The second stroke occurred 5 weeks to 11 months after stopping transfusions (median 3 months) in 7/10 patients.18( C) Similar results were found in another 10 children with SCA and previous stroke (median 9½ years, range 5–12 years) after stopping pRBC transfusions (HbS < 30%): high recurrence rate within 12 months.
Sickle cell disease
2016, Handbook of Clinical NeurologyCitation Excerpt :Regular transfusion of sickle-negative blood to maintain a trough hemoglobin S less than 30% of total hemoglobin is the most commonly used therapy for the secondary prevention of stroke. Recurrence rates after first ischemic stroke are as high as 67%, but decrease to 2–4 per 100 person-years with regular transfusions of sickle-negative blood (Wilimas et al., 1980; Wang et al., 1991; Balkaran et al., 1992). Transfusion is the most frequently used therapy in children, but there is some evidence that hydroxyurea also reduces stroke recurrence.
How i treat and manage strokes in sickle cell disease
2015, BloodCitation Excerpt :Given the multiple options of therapy for this patient, a family meeting was deemed critical to ensure a full understanding of the trade-offs for a secondary stroke prevention option. The possibility of stopping transfusion therapy was mentioned with the recognition that this would have the highest rate of recurrence.88,89 We also discussed the evidence that regular blood transfusion is not the definitive therapy, and we expect 45% of patients will have a new cerebral infarct7 over a course of 5.5 years.
Stroke With Transfusions Changing to Hydroxyurea (SWiTCH)
2012, BloodCitation Excerpt :An effective therapeutic target for transfusions is 30% HbS, associated with a 14% to 23% incidence of secondary stroke and event rate of 2.2-6.4 recurrent strokes per 100 patient-years.3,7,8 Unfortunately, chronic transfusions are administered indefinitely, because of the high stroke recurrence rate after discontinuation of short-term9 or long-term10 transfusions. Consequently, young patients with SCA and stroke remain on lifelong chronic transfusions with almost no available alternatives, and develop transfusion-associated problems including infections, erythrocyte auto/alloimmunization, iron overload requiring chelation therapy, and reduced expected number of quality-adjusted life years.11-15
