title: Streptococcal bacteremia in neutropenic adult patients.
abstract: In order to define the circumstances of occurrence, clinical presentation and prognostic factors of streptococcal bacteremia in neutropenic patients, we retrospectively reviewed 60 cases of streptococcal bacteremia following intensive chemotherapy for acute myeloblastic leukemia (AML), acute lymphoblastic leukemia (ALL) or allogeneic bone marrow transplantation. Causative streptococcal species included streptococcus viridans (42 cases), streptococcus faecalis (12), streptococcus pneumoniae (4) and other streptococci (2). All patients were febrile and 32% presented diffuse pneumopathy with frequent isolation of streptococci from bronchoalveolar washing fluids. There were no statistical differences in presentation between the bacteremia caused by different streptococcal species. Death occurred in 22% of the patients and factors favoring poor prognosis included pneumopathy (p less than 0.001), more than 2 positive blood cultures (p less than 0.01) and initial chemotherapy for AML (p less than 0.01). Pneumopathy occurred more frequently after chemotherapy for AML. It is concluded that streptococcal bacteremia is to be prevented in patients undergoing intensive chemotherapy, particularly if cytarabine is used.
