[Early diagnosis and management against perioperative fungus infection]

Candida spp. is frequently detected from perioperative patients, especially from those requiring central venous catheter (CVC) management. CAND-TEC could detect the blood fungus infection easily and quickly. We analyzed 438 specimens from 57 patients requiring perioperative CVC management for more than three weeks, and investigated usefulness of CAND-TEC comparing with other serological methods. The dilution rate of CAND-TEC showed a positive correlation with amount of beta-D-glucan which was measured by Toxicolor test and Endotoxin-specific assay. It also showed a positive correlation with amount of D-arabinitol. When blood samples diluted more than four times were positive with CAND-TEC, the patients were considered to be infected, and accumulative infection rate was up to 84.2% three weeks after introduction of CVC management. CAND-TEC would be useful in detecting Candida infection compared with conventional methods, and the fungus infection was much more frequent incidence than ever expected. It is important to detect fungus infection early and respond immediately to avoid nosocomial infection.
