OBJECTIVE: To assess the effect on survival of macrolides or fluoroquinolones in intubated patients admitted to the intensive care unit (ICU) with severe community-acquired pneumonia (severe CAP).
METHODS: Prospective, observational cohort, multicenter study conducted in 27 ICUs of 9 European countries. Two hundred eighteen consecutive patients requiring invasive mechanical ventilation for an admission diagnosis of CAP were recruited.
RESULTS: Severe sepsis and septic shock were present in 165 (75.7%) patients. Microbiological documentation was obtained in 102 (46.8%) patients. ICU mortality was 37.6% (n = 82). Non-survivors were older (58.6 +/- 16.1 vs. 63.4 +/- 16.7 years, P<0.05) and presented a higher score on the simplified Acute Physiology Score II at admission (45.6 +/- 15.4 vs. 50.8 +/- 17.5, P<0.05). Monotherapy was given in 43 (19.7%) and combination therapy in 175 (80.3%) patients. Empirical antibiotic therapy was in accordance with the 2007 Infectious Diseases Society of America (IDSA)/American Thoracic Society (ATS) guidelines in 100 (45.9%) patients (macrolides in 46 patients and fluoroquinolones in 54). In this cohort, a Cox regression analysis adjusted by severity identified that macrolide use was associated with lower ICU mortality (hazard ratio, HR 0.48, confidence intervals, 95% CI 0.23-0.97, P = 0.04) when compared to the use of fluoroquinolones. When more severe patients presenting severe sepsis and septic shock were analyzed (n = 92), similar results were obtained (HR 0.44, 95% CI 0.20-0.95, P = 0.03).
CONCLUSIONS: Patients with severe community-acquired pneumonia had a low adherence with the 2007 IDSA/ATS guidelines. Combination therapy with macrolides should be preferred in intubated patients with severe CAP.

This report updates previous recommendations by CDC's Advisory Committee on Immunization Practices (ACIP) regarding the use of antiviral agents for the prevention and treatment of influenza (CDC. Prevention and control of influenza: recommendations of the Advisory Committee on Immunization Practices [ACIP]. MMWR 2008;57[No. RR-7]).This report contains information on treatment and chemoprophylaxis of influenza virus infection and provides a summary of the effectiveness and safety of antiviral treatment medications. Highlights include recommendations for use of 1) early antiviral treatment of suspected or confirmed influenza among persons with severe influenza (e.g., those who have severe, complicated, or progressive illness or who require hospitalization); 2) early antiviral treatment of suspected or confirmed influenza among persons at higher risk for influenza complications; and 3) either oseltamivir or zanamivir for persons with influenza caused by 2009 H1N1 virus, influenza A (H3N2) virus, or influenza B virus or when the influenza virus type or influenza A virus subtype is unknown; 4) antiviral medications among children aged<1 year; 5) local influenza testing and influenza surveillance data, when available, to help guide treatment decisions; and 6) consideration of antiviral treatment for outpatients with confirmed or suspected influenza who do not have known risk factors for severe illness, if treatment can be initiated within 48 hours of illness onset. Additional information is available from CDC's influenza website at http://www.cdc.gov/flu, including any updates or supplements to these recommendations that might be required during the 2010-11 influenza season. Health-care providers should be alert to announcements of recommendation updates and should check the CDC influenza website periodically for additional information. Recommendations related to the use of vaccines for the prevention of influenza during the 2010-11 influenza season have been published previously (CDC. Prevention and control of influenza with vaccines: recommendations of the Advisory Committee on Immunization Practices [ACIP], 2010. MMWR 2010;59[No. RR-8]).
