Treatment of bone and joint infections can be challenging as antibiotics should penetrate through the rigid bone structure and into the synovial space. Several pharmacokinetic studies measured the extent of penetration of different antibiotics into bone and joint tissues. This review discusses the results of these studies and compares them with minimum inhibitory concentrations (MIC) of common pathogens implicated in bone and joint infections in order to determine which antibiotics may have a greater potential in the treatment of such infections...

Sepsis mortality has improved following advancements in early recognition and standardized management, including emphasis on early administration of appropriate antimicrobials. However, guidance regarding antimicrobial duration in sepsis is surprisingly limited. Decreased antibiotic exposure is associated with lower rates of de novo resistance development, Clostridioides difficile-associated disease, antibiotic-related toxicities, and health care costs. Consequently, data weighing safety versus adequacy of shorter treatment durations in sepsis would be beneficial...

Background: Staphylococcus aureus bloodstream infections (BSIs) are associated with significant morbidity and mortality. Ceftriaxone is convenient for outpatient parenteral antimicrobial therapy (OPAT), but data for this indication are limited. Methods: Adult patients with methicillin-susceptible Staphylococcus aureus (MSSA) BSI discharged on OPAT with cefazolin, oxacillin, or ceftriaxone for at least 7 days were included. We compared outcomes of ceftriaxone vs either oxacillin or cefazolin...

BACKGROUND: Limited data exist regarding the efficacy of piperacillin-tazobactam (TZP) for the management of nonbacteremic pyelonephritis caused by extended-spectrum β-lactamase (ESBL)-producing organisms. METHODS: We conducted a multicenter observational study comparing clinical outcomes of adults hospitalized with ESBL-producing pyelonephritis who were receiving TZP versus carbapenems, using an inverse probability of treatment weighted propensity score analysis...

Delafloxacin (ABT 492) is a new fluoroquinolone available in both oral and parenteral formulations. It has recently been approved by the Food and Drug Administration for the management of acute bacterial skin and skin structure infections. When compared to combination therapy of vancomycin and aztreonam, delafloxacin was not inferior and had a favorable adverse event profile. Furthermore, its anti-methicillin-resistant Staphylococcus aureus (MRSA) activity and favorable clinical response in MRSA infections distinguishes it from other fluoroquinolones...
