ReviewFosfomycin for the treatment of infections caused by multidrug-resistant non-fermenting Gram-negative bacilli: a systematic review of microbiological, animal and clinical studies.
The treatment of multidrug-resistant (MDR), extensively drug-resistant or pandrug-resistant non-fermenting Gram-negative bacterial infections constitutes a challenge in an era of few new antibiotic choices. This mandates the re-evaluation of already existing antibiotics such as fosfomycin. We systematically reviewed the literature to assess the clinical and microbiological effectiveness of fosfomycin in the treatment of these infections by searching PubMed, Scopus and the Cochrane Library databases. ⋯ In six clinical studies, 33 patients with MDR P. aeruginosa infections (mainly pulmonary exacerbations of cystic fibrosis) received fosfomycin (25/33 in combination with other antibiotics); 91% of the patients clinically improved. In conclusion, fosfomycin could have a role as a therapeutic option against MDR P. aeruginosa infections. Further research is needed to clarify the potential utility of this agent.
