ReviewImplications for antimicrobial prescribing of strategies based on bacterial eradication.
Antimicrobial prescribing in respiratory tract infection is generally empirical. Agents that do not eradicate the key bacterial respiratory pathogens (Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis) provide suboptimal therapy. A recent paper developed by a multidisciplinary, multinational group presented a consensus on the principles that should underpin appropriate antimicrobial prescribing. ⋯ Changes in prescribing habits should be considered carefully, to avoid unintended negative consequences. It is the responsibility of physicians to ensure that each prescription is necessary and will maximize the potential for clinical cure, but there is also a collective responsibility to sustain the diversity of antimicrobial therapy via appropriate formularies, guidelines and licensing, reduced over-the-counter availability, and continued research and development through academia and industry. To maximize clinical cure and minimize the emergence and spread of resistance, antimicrobial prescribing should maximize bacterial eradication, and clinical drug evaluation needs to be brought into line with this need.

Bacteremic pneumococcal infections in immunocompromised patients without AIDS: the impact of beta-lactam resistance on mortality.
Streptococcus pneumoniae is the leading cause of community-acquired pneumonia in the elderly, and in recent years it has arisen as an important pathogen in HIV-infected patients. However, there is a scarcity of information on clinical and therapeutic problems associated with pneumococcal infections in other immuno-compromised patients. The objective of this study was to assess the most relevant epidemiologic aspects, clinical features and prognostic factors of pneumococcal bacteremia in immunocompromised hosts without AIDS. ⋯ Much of the burden of pneumococcal bacteremia was attributable to immunosuppressive diseases. In immunocompromised patients, pneumococcemia was frequently acquired within the hospital during the treatment of the underlying condition, and resistance to penicillin was common. Patients with acute leukemia and lymphoma who develop fever and pneumonia should be treated with drugs active against beta-lactam-resistant pneumococci, irrespective of the setting in which the infection develops.
