Abstract:

The purpose of the study was to assess the risk of first-time bloodstream infection (BSI) according to type of central venous catheter (CVC) during induction therapy in children with acute lymphoblastic leukemia (ALL). Patients eligible for our analysis were all newly diagnosed children with ALL treated at 3 pediatric centers in Denmark between 2008 and 2014.

A total of 136 patients were followed from initial CVC placement until first BSI, CVC removal, death, or day 28, whichever occurred first. Thirty-nine BSIs were detected, of which 67% were gram-positive infections, and 59% met the criteria for being CVC associated. The 28-day cumulative incidence of BSI was similar in 77 patients with a nontunneled CVC (28%; 95% confidence interval, 19%-40%) and in 59 patients with a tunneled CVC with external lines (TE) (33%; 95% confidence interval, 23%-47%). Subgroup analyses showed that gram-negative blood isolates occurred more frequently in patients with a TE, and that lower incidences of BSI were detected in patients older than 9 years with a TE, and in patients with T-ALL. It is concluded that the type of CVC inserted at diagnosis has no impact upon the risk of BSI in patients with ALL undergoing induction therapy.
