Sulfamethoxazole-Trimethoprim-Resistant Pneumococcal Sepsis

JAMA. 1982;248(22):3011-3012. doi:10.1001/jama.1982.03330220055038

THE SUCCESS of bone marrow transplantation in the treatment of aplastic anemia and acute leukemia has resulted in an increasingly large number of long-term survivors of this procedure.

The occurrence of infections in these patients has been recognized as a major cause of morbidity and mortality, particularly in those patients in whom chronic graft-v-host disease develops.1Streptococcus pneumoniae has been noted to cause a substantial portion of the reported infections,1,2 and it has been suggested that immunization with polyvalent pneumococcal vaccine and long-term antibiotic prophylaxis be used to prevent this complication.2

Reports of pneumococci both resistant to penicillin in vitro and producing clinically important infection have been a cause of great concern.3 While some of these organisms have been found to be resistant to sulfamethoxazole-trimethoprim as well as penicillin,3 there have been, to our knowledge, no reports of penicillin-sensitive/sulfamethoxazole-trimethoprim-resistant pneumococci causing clinical infection. We report
