The number of studies evaluating teicoplanin lock therapy in coagulase-negative staphylococcus-associated catheter infection in pediatric malignancies is limited. The aim of this study was to evaluate the efficacy of teicoplanin lock therapy in pediatric cancer cases. Twenty-two patients with coagulase-negative staphylococcus-associated totally implantable venous access device infection, who had undergone teicoplanin closure treatment, were included in the study. Demographic data, number of lock treatment days, and treatment success data were obtained from the medical files of the patients. Fourteen of the patients (63.6%) had acute lymphocytic leukemia, 3 (13.6%) had acute myelocytic leukemia, and 5 (22.7%) had solid cancer. The median neutrophil count was 240×103/μL (interquartile range: 0 to 1195×103/μL). Between patients with and without catheter removal, no statistically significant difference was found in terms of baseline C-reactive protein, absolute neutrophil count, and the day of starting systemic teicoplanin treatment (P>0.05). The overall port survival rate of teicoplanin lock therapy was 72.7%. Within an average of 4 days, negative cultures of 16 (72.7%) patients whose catheters had not been removed were obtained. In conclusion, we suggest that teicoplanin lock therapy is an effective and safe treatment for catheter-related infections, caused by methicillin-resistant coagulase-negative staphylococcus.
