bacteremia in patients with hematologic disorders: a case series and systematic literature review.

is generally considered a contaminant in clinical practice. However, it may cause bacteremia in patients with hematologic disorders, and factors that contribute to its mortality are unclear. A case series and systematic literature review identified 96 cases of bacteremia inhematologic disorderpatients. The median age was 50.5 years (range: 2-93 years), with 79 (82%) patients 18 years or older, and 64 (67%) patients male. Most cases involved hematologic malignancies, and neutropenia was observed in approximately 75% cases. The most common sites of infection/symptoms were skin and soft tissue, respiratory, and catheter-related bloodstream infection. The infection-related mortality was 23%, and univariate analysis showed that age, respiratory infection/symptoms, and source control were significantly associated with infection-related mortality. Multivariate analysis indicates that infection-related mortality was significantly reduced by source control (OR: 0.24, 95% CI: 0.06-0.97,  = 0.046). Therefore, when infections are suspected, early source control should be considered.
