Linezolid is currently indicated to treat vancomycin-resistant Enterococcus faecium infections, nosocomial pneumonia caused by Staphylococcus aureus or Streptococcus pneumoniae, complicated and uncomplicated skin and skin structure infections, and community-acquired pneumonia. We report a case of linezolid-induced lactic acidosis during treatment of vancomycin-resistant enterococcal bacteremia after mitral valve replacement and permanent pacemaker implantation. We also review the current literature describing other cases of linezolid-associated hyperlactatemia.

Patients admitted to intensive care units (ICUs) are at a high risk of acquiring blood stream infections. We examined whether SOFA score on ICU admission and on the day of bacteremia can predict the occurrence of bacteremia and the outcome of bacteremic ICU patients. ⋯ Admission SOFA score is independently associated with the occurrence of ICU-acquired bacteremia, whereas it is not sufficient to predict the outcome of patients who subsequently will develop this complication. However, SOFA score on the first day of bacteremia is an independent prognostic factor for outcome in these patients.

Over the last two decades, an alarming rise in infections caused by antibiotic-resistant microbes has been paralleled by an equally alarming decline in the development of new antibiotics to deal with the threat. In response to this brewing "perfect storm" of infectious diseases, the Infectious Diseases Society of America (IDSA) has released a white paper that proposes incentives to stimulate critically needed antibiotic development by pharmaceutical companies. A cornerstone of the recommendations is establishment of a "wild-card patent extension" program. This program would allow a company receiving United States (US) Food and Drug Administration (FDA) approval for a new anti-infective agent targeting a drug-resistant pathogen to extend the patent on a drug within their active portfolio. However, wild-card patent extension legislation is highly controversial due to concerns regarding its societal cost. ⋯ Wild-card patent extension appears to be a cost-effective strategy to spur anti-infective development. Although our analysis is limited by the precision of published data, our model employed conservative assumptions.

Despite improvements in diagnostic and therapeutic approach to adult patients with bacterial meningitis, the overall mortality rate is still high. The aim of this study was to evaluate antibiotic timing in the course and outcome of bacterial meningitis. ⋯ Our study emphasizes the importance of early and adequate antibiotic treatment in the management of bacterial meningitis which significantly enhances the chances for favorable outcome.

Simultaneous co-infections of Borrelia burgdorferi sensu lato and HIV-1 are rare events, with only six published cases. A case of acute neuroborreliosis with facial palsy, meningoradiculitis (Bannwarth's syndrome) in an HIV-1 positive individual is described. ⋯ The patient was successfully treated with cefotaxime. In all published HIV+ cases, the course of borreliosis did not differ from that of the HIV negative population and the prognosis in properly treated patients was good.
