Four patients (3 long-term Hodgkin disease survivors and 1 recipient of an
allogeneic bone marrow transplant) developed severe infections with Strepto
coccus pneumoniae after staging splenectomy or due to functional hypospleni
sm after total body irradiation and bone marrow transplantation. Current gu
idelines for prevention of infection recommend pneumococcal immunization fo
r patients with Hodgkin disease treated with splenectomy and others with fu
nctional hyposplenism. Booster vaccination after 5 years is also advised. H
ospital- and community-based vaccination initiatives may help identify at-r
isk patients.
