Background: Infections are the major cause for treatment failure in acute leukemias. They mostly present as fever of unknown origin (FUO), a smaller but prognostically unfavorable group are pneumonias. The effective management of infectious complications requires a symptom and response adapted interventional strategy.
Therapeutical approach: In case of FUO standard therapy consists of the two drug combination of aminoglycoside plus acylaminopenicillin or third generation cephalosporine. In case of non-response carbapenems and a glycopeptide should be applied and a systemic antifungal treatment must be initiated. In pneumonia amphotericin B should be added to antibiotics already initially. Potent single agents with a broad spectrum of activity as well as new antifungal drugs provide attractive perspectives for future evaluations.
Conclusions: By a consequent step-wise oscalating interventional treatment strategy infections in patients with acute leukemias can be successfully treated.
