ABSTRACT
PURPOSE OF REVIEW Whereas Staphylococcus aureus remains the leading cause of skin and soft tissue infections (SSTI), Gram-negative bacilli (GNB) are increasingly reported as a cause of monomicrobial or polymicrobial infections. This review examines the expanding role of GNB in SSTI and discusses the risks for and the frequency of multidrug-resistance (MDR) and extensive drug-resistance (XDR) and the implications with regard to outcome and therapy. RECENT FINDINGS:
Although the global epidemiology and role of GNB in SSTIs have not been studied systematically, complicated SSTIs caused by resistant GNB are increasing particularly in vulnerable patients with long-standing infections, those in long-term care facilities, and those with a history of recent hospitalization or prior antibiotic therapy. Mixed infections also occur in up to 25% of SSTIs, and inappropriate therapy occurs in 40% of cases. Prompt identification of the causative pathogen requires that patients with SSTI be risk stratified according to the likelihood of resistance to enable early recognition and swift initiation of appropriate therapy.SUMMARY:
For individual treatment decisions in SSTIs, institutional diagnostic and treatment algorithms based on local epidemiology and risk factors are pivotal to reducing the incidence of treatment failure and improving outcomes associated with resistant GNB.
