Randomized Controlled Trial
Predictors of serological cure and Serofast State after treatment in HIV-negative persons with early syphilis.
Syphilis management requires serological monitoring after therapy. We compared factors associated with serological response after treatment of early (ie, primary, secondary, or early latent) syphilis. ⋯ Serological cure at 6 months after early syphilis treatment is associated with age, number of sex partners, Jarisch-Herxheimer reaction, and an interaction between syphilis stage and baseline RPR titer.

Methicillin-resistant Staphylococcus aureus (MRSA) colonization is a predictor of subsequent infection in hospitalized adults. The risk of subsequent MRSA infections in hospitalized children colonized with MRSA is unknown. ⋯ MRSA colonization is a risk factor for subsequent MRSA infection in children. Although MRSA colonized children may have lower risks of subsequent infection than adults, children who acquire MRSA in the hospital have similarly high rates of infection. Preventing transmission of MRSA in hospitalized children should remain a priority.

Colistin, originally abandoned due to high rates of nephrotoxicity, has been recently reintroduced due to activity against carbapenem-resistant Gram-negative organisms. Recent literature, largely obtained from outside the United States, suggests a lower rate of nephrotoxicity than historically reported. ⋯ In this retrospective cohort, nephrotoxicity (as defined by RIFLE criteria) occurred among 43% of treated patients in a dose-dependent manner. Higher colistin doses, similar to those commonly used in the United States, led to a relatively high rate of nephrotoxicity. These data raise important questions regarding the safe use of colistin in the treatment of multidrug-resistant pathogens.
