The microbiology of diabetic foot infections in Korea

초록

Background In diabetic foot infection, causative pathogens differ in Western population as compared with Asian population. The aim of this study is to analyze microbiological data with respect to diabetic foot infection in Korea to help the choice adequate empirical antibiotics. Methods We enrolled 745 patients with diabetic foot infection, who were admitted to diabetic wound center of the Korea University Guro Hospital between January 2011 and December 2015. Deep tissue and/or bone biopsy cultures were taken during surgical debridement in the operating room and microbiological analysis was performed. Results Out of the 745 patients, 613 patients (82.2%) had isolated causative organisms and 832 microbial isolates were identified. Gram-positive aerobic bacteria were isolated in 57.5%, followed by Gram-negative aerobic bacteria (40.0%), anaerobes (1.4%), and fungus (1.1%). MRSA found most frequently identified (13.7%) in Gram-positive aerobes and Pseudomonas found most frequently identified (9.4%) in Gram-negative aerobes. Conclusion Microbiologic analysis in Korea differs from the reports from Western population. We propose the need of our own guidelines based on microbiology of Korea for better treatment.
