RESUMEN
We conducted a clinical study involving cases of central venous(CV)port-related infection in Tokyo Rosai Hospital. Fourteen patients with suspected CV port-related infection at Tokyo Rosai Hospital between April 2015 and January 2017 were observed. Identical bacterial types were detected from 2 sets of blood cultures and cultures from the catheter tip, and a definitive diagnosis was made. Data on patient background, causative bacteria, quick sequentialorgan failure assessment (qSOFA)score, CV port placement period, presence or absence of local inflammatory findings, and prognosis were analysed. The causative bacteria were coagulase-negative Staphylococcus(CNS)in 7 cases(50%), Staphylococcus aureus in 3(21%), and Candida in 4(29%). Most CNS-infected cases(71%)exhibited a qSOFA score of 1 or less at the examination time, which indicated that even if bacteremia occurred in CNS cases, organopathy might not occur easily. Local inflammatory findings were found in only 3 CNS cases. Cases without local inflammatory findings showed methicillin-resistant Staphylococcus aureus(MRSA)(18%)or Candida(36%)at high proportions, indicating that treatments might be difficult.
