Abstract
Hemoglobin SD-Los Angeles is an uncommon sickle hemoglobinopathy. We describe a boy with dccumented Hb SD-Los Angeles who had experienced acute splenic sequestration, pnelrmococcal sepsis, aplastic crisis and functional asplenia during his first two years of life. We suggest that children with Hb SD-Los Angeles are at similar risks for the 1 if e- t hreatening complications which characterize sickle cell anemia and should receive the same comprehensive medical care currently recommended for children with Hb SS disease.
