Reactive oxygen therapy: a novel therapy in soft tissue infectionDryden, MatthewCurrent Opinion in Infectious Diseases: April 2017 - Volume 30 - Issue 2 - p 143–149 doi: 10.1097/QCO.0000000000000350 SKIN AND SOFT TISSUE INFECTIONS: Edited by Matteo Bassetti Abstract Author Information Purpose of review The global burden of disease in skin and soft tissue lesions is enormous. Many chronic, poorly healing lesions get treated with antibiotics despite the lack of evidence for long-term antibiotics. There is a global antibiotic resistance crisis driven largely by inappropriate use of large volumes of antibiotics. One solution is to reduce the selection pressure on bacteria by reducing the volume of antibiotic use in medicine, agriculture and the environment. There are few novel antimicrobials. One of the only novel agents to reach clinical use is one using reactive oxygen species (ROS), oxygen radicals, as an antimicrobial mechanism. Recent findings ROS can be delivered to the site of infection in various formats. ROS is highly antimicrobial against Gram-positive and negative bacteria, viruses and fungi. It also prevents and breaks down biofilm. These functions make ROS highly suitable for chronic inflammatory conditions, where antibiotics are frequently overused and relatively ineffective: chronic wounds, ulcers and burns; but also possibly mucosal infections in the respiratory and urinary tracts and in prosthetic device infection. ROS could also have an important role in infection prevention and antimicrobial stewardship. Summary Early clinical data support ROS treatment in skin and soft tissue lesions to reduce bacterial bioburden and biofilm in critical colonization and in preventing surgical site infection, although further trials of ROS in soft tissue infection would be helpful and research in ROS use at other clinical sites might support many novel clinical indications. aHampshire Hospitals Foundation NHS Trust, Hampshire bUniversity of Southampton, Faculty of Medicine, Southampton, UK Correspondence to Dr Matthew Dryden, Royal Hampshire County Hospital, Winchester S022 5DG, UK.
