Hyposplenism as a complication of celiac sprue confers an increased ri
sk of pneumococcal sepsis, but such patients do not routinely receive
pneumococcal vaccine despite reports of overwhelming pneumococcal seps
is. Because antibody response in these patients has not been previousl
y assessed, we measured pre- and postvaccination levels in 10 patients
with documented sprue. All demonstrated appropriate acute antibody re
sponses to a polyvalent pneumococcal vaccine. Vaccination of all patie
nts with celiac sprue seems appropriate.
