Abstract:
Vancomycin is still frequently started empirically in febrile neutropaenia, especially when patients are severely ill. Yet randomized evidence concerning anti-Gram-positive agents as a class shows no mortality benefit from routine empirical coverage, and contemporary cohort studies consistently link early shock and death to Gram-negative bacilli, inadequate Gram-negative coverage, pneumonia, septic shock and candidaemia rather than to Gram-positive bacteraemia or inadequate Gram-positive coverage. MRSA nasal screening further supports avoiding empirical anti-MRSA therapy in screen-negative patients. The default response to febrile neutropaenia should therefore be rapid, locally informed anti-pseudomonal beta-lactam therapy, with vancomycin reserved for documented infection or narrowly defined syndromes with a high pre-test probability of resistant Gram-positive disease.

Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
