Randomized Controlled Trial Multicenter Study Comparative Study
Single-dose oritavancin versus 7-10 days of vancomycin in the treatment of gram-positive acute bacterial skin and skin structure infections: the SOLO II noninferiority study.
Oritavancin is a lipoglycopeptide antibiotic with rapid bactericidal activity against gram-positive bacteria. Its concentration-dependent activity and long half-life allow for single-dose treatment. ⋯ A single 1200-mg dose of oritavancin was noninferior to 7-10 days of vancomycin in treating ABSSSIs caused by gram-positive pathogens, and was well tolerated. Oritavancin provides a single-dose alternative to multidose therapies for the treatment of ABSSSIs. Clinical Trials Registration. NCT01252732.

Bedaquiline is a new antibiotic that was approved for the treatment of multidrug-resistant (MDR) tuberculosis. We aimed to evaluate the short-term microbiological efficacy and the tolerability profile of bedaquiline. ⋯ The use of bedaquiline combined with other active drugs has the potential to achieve high culture conversion rates in complicated MDR and XDR tuberculosis cases, with a reassuring safety profile at 6 months of treatment.

A recent increase in Bordetella pertussis without the pertactin protein, an acellular vaccine immunogen, has been reported in the United States. Determining whether pertactin-deficient (PRN(-)) B. pertussis is evading vaccine-induced immunity or altering the severity of illness is needed. ⋯ The significant association between vaccination and isolate pertactin production suggests that the likelihood of having reported disease caused by PRN(-) compared with PRN(+) strains is greater in vaccinated persons. Additional studies are needed to assess whether vaccine effectiveness is diminished against PRN(-) strains.

Sepsis is a serious complication of solid organ transplant (SOT). Evidence on survival differences between SOT recipients and non-SOT patients with sepsis is lacking. ⋯ The 28-day and 90-day mortality were significantly decreased for transplant recipients compared with nontransplant patients. These findings suggest that the immunosuppression associated with transplantation may provide a survival advantage to transplant recipients with sepsis through modulation of the inflammatory response.

Sensitive diagnostic assays have increased the detection of viruses in asymptomatic individuals. The clinical significance of asymptomatic respiratory viral infection in infants is unknown. ⋯ Compared to symptomatic infection, asymptomatic viral infection in infants is associated with young age, male sex, low viral load, specific viruses, and single virus detection. Asymptomatic viral infection did not result in AOM.
