Roseomonasspecies infections in humans: a systematic review

摘要

Roseomonasspecies have been recognized to cause infections in immunocompromised individuals. The purpose of this study was to systemically review all published cases ofRoseomonasinfections in humans and describe the epidemiology, microbiology, antimicrobial susceptibility, treatment and outcomes of these infections in humans. We performed a systematic review of PubMed (through 20(th)Octrober 2019) for studies providing epidemiological, clinical, microbiological as well as treatment data and outcomes ofRoseomonasspecies infections. A total of 37 studies, containing data of 99 patients, were included in the analysis. The most commonRoseomonasinfections were those of the bloodstream in 74.7% (74 patients), musculoskeletal infections in 8.1% (8 patients), skin and soft tissue infections (SSTIs) and peritoneal dialysis-associated peritonitis in 6.1% (6 patients) each. Epidemiology of these infections differed, with bacteremias being more prevalent in patients with malignancy and central venous lines, musculoskeletal infections being more prevalent after orthopedic surgery, and SSTIs occurring without any reported underlying cause. Resistance to beta-lactams was very high with penicillin, piperacillin/tazobactam resistance and cephalosporin resistance at 96.6%, 90.7% and 77.8% respectively, while quinolone resistance was 9.1%. Quinolones, carbapenems and cephalosporins are the most common agents used for treatment, irrespectively of the infection site. Overall mortality was 3% (3 patients), with the mortality attributed toRoseomonasbeing at 1% (1 patient).
