BackgroundCentral venous catheter-related (CVC) infections represent the most common complication of parenteral nutrition. These infections are usually treated by means of long-term systemic antibiotic treatment. The objective of this study was to determine the efficacy of combining a local antibiotic lock with a short systemic double antibiotic to treat CVC-related staphylococci infections.MethodsAny child with coagulase-negative staphylococci or Staphylococcus aureus septicemia, confirmed by a positive blood culture, was included in the study. A double antibiotic systemic treatment composed of amikacin and teicoplanin was started and continued for 5 days. The antibiotic treatment was combined from the first day (D0) with a local teicoplanin lock, which was left for 12 hours a day in the catheter for 15 days. Parenteral nutrition was continued on a nocturnal cyclic mode during antibiotic treatment. The efficacy of the treatment was evaluated by clinical (body temperature), biologic [C-reactive protein levels (CRP)], and bacteriologic (blood culture) measures.ResultsTwenty CVC-related infection episodes in 13 patients were analyzed for the study. In the initial biologic test, CRP varied from 2 to 130 mg/L (mean 43 mg/L). After 3 days of treatment, CRP varied from 2 to 61 mg/L (mean 12 mg/L). The median time until normalization of temperature and CRP levels after the beginning of antibiotic treatment was 3.2 days (range 1 to 14 days) and 6.2 days (range 2 to 19 days), respectively. All blood cultures were negative for infection 48 hours after stopping the treatment. Only 1 therapeutic failure was observed during the treatment. The patient had persistent signs of clinical septicemia that required removal of the CVC. Two catheter-related infection recurrences were observed in the month after termination of the local antibiotic lock, which also required removal of the CVC. The central venous catheter was maintained in the other cases.ConclusionsTeicoplanin antibiotic locks, combined with a short conventional systemic antibiotic treatment and continuation of cyclic parenteral nutrition, seem effective and well-tolerated treatments for CVC infections.
