The authors sought to determine if citrulline was associated with the development of catheter\u2010related bloodstream infections (CRBSIs) in children with intestinal failure. <jats:italic>Methods:<\/jats:italic> Data were reviewed from 66 children treated in a multidisciplinary intestinal rehabilitation program, who had serum concentration citrulline measured between January 2007 and August 2009. All patients had a diagnosis of intestinal failure requiring parenteral nutrition (PN) support. Exclusion criteria included central venous catheter in situ &lt;30 days, creatinine clearance &lt;20 mL\/minute, or a history of organ transplant\/immunosuppression. <jats:italic>Results:<\/jats:italic> A total of 15 patients were excluded because of the above criteria. In this cohort of 51 patients, 26 (51%) developed CRBSIs. Both groups were similar in terms of gestational age, diagnosis, nutrition status, and biochemical liver function tests. The mean (\u00b1 standard deviation [SD]) minimum serum citrulline concentration was significantly lower in patients who developed CRBSIs (6.7 \u00b1 4.6 \u00b5mol\/L) than in those who did not (11.3 \u00b1 6.4 \u00b5mol\/L, <jats:italic>P<\/jats:italic> = .004). Multivariate logistic regression analysis identified lower minimum serum citrulline concentration and longer central venous catheter duration as independently associated with CRBSI (<jats:italic>P<\/jats:italic> = .003 and <jats:italic>P<\/jats:italic> = .038, respectively). <jats:italic>Conclusions:<\/jats:italic> Low serum citrulline concentration and longer central venous catheter time are independently associated with CRBSI in children with intestinal failure. Serum citrulline concentration may be a useful biomarker to identify patients with intestinal failure who are at high risk of developing a CRBSI.<\/jats:p>","DOI":"10.1177\/0148607110381406","type":"journal-article","created":{"date-parts":[[2011,3,5]],"date-time":"2011-03-05T08:05:38Z","timestamp":1299312338000},"page":"181-187","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":25,"title":["Low
