Data suggest that higher doses of vancomycin can increase the risk of nephrotoxicity. No study has been undertaken to determine the pharmacodynamic index (ie, the area under the curve [AUC] or the trough value) that best describes the relationship between vancomycin exposure and onset of nephrotoxicity. ⋯ The results indicate that a vancomycin exposure-toxicity response relationship exists. The vancomycin trough value is the pharmacodynamic index that best describes this association.

We assessed the kinetics of the humoral immune response to pertussis antigens following vaccination of health care personnel with adult tetanus-diphtheria-acellular pertussis vaccine (Tdap). By 2 weeks after vaccination, 88%-94% of subjects demonstrated a booster response. This brisk response of adults to Tdap supports a role for vaccination in pertussis outbreak control.

Comparative Study Clinical Trial
Salvage treatment for persistent methicillin-resistant Staphylococcus aureus bacteremia: efficacy of linezolid with or without carbapenem.
Persistent methicillin-resistant Staphylococcus aureus (MRSA) bacteremia is associated with high mortality rates, but no treatment strategy has yet been established. We performed this study to evaluate the efficacy of linezolid with or without carbapenem in salvage treatment for persistent MRSA bacteremia. ⋯ Linezolid-based salvage therapy effectively eradicated S. aureus from the blood for patients with persistent MRSA bacteremia. The salvage success rate was higher for linezolid therapy than for vancomycin-based combination therapy.
