[Infections in stem cell transplantation]

Abstract

The morbidity and mortality associated with infections in stem cell transplantation (SCT) has decreased considerably in recent years because of increasing knowledge of related risk factors, immune recovery, and the pattern of infection according to the phase of evolution of SCT, and the introduction of new and more effective antimicrobial agents. These advances, together with the use of peripheral blood stem cells, T-lymphoid cell depletion, stimulating factors, and more potent immunosuppressors has reduced SCT mortality and broadened the indications for this treatment. Nevertheless, infection continues to a prominent complication in these patients.
