Abstract

BACKGROUND: Coagulase-negative staphylococci (CoNS) are an infrequent cause of native valve endocarditis (NVE), and our understanding of NVE caused by CoNS is incomplete. METHOD: The International Collaboration on Endocarditis-Prospective Cohort Study includes patients with endocarditis from 61 centers in 28 countries. Patients with definite cases of NVE caused by CoNS who were enrolled during the period June 2000-August 2006 were compared with patients with definite cases of NVE caused by Staphylococcus aureus and patients with NVE caused by viridans group streptococci. Multivariable logistic regression was used to determine factors associated with death in patients with NVE caused by CoNS. RESULTS: Of 1635 patients with definite NVE and no history of injection drug use, 128 (7.8%) had NVE due to CoNS. Health care-associated infection occurred in 63 patients (49%) with NVE caused by CoNS. Comorbidities, long-term intravascular catheter use, and history of recent invasive procedures were similar among patients with NVE caused by CoNS and among patients with NVE caused by S. aureus. Surgical treatment for endocarditis occurred more frequently in patients with NVE due to CoNS (76 patients [60%]) than in patients with NVE due to S. aureus (150 [33%]; P=.01) or in patients with NVE due to viridans group streptococci (149 [44%]; P=.01). Despite the high rate of surgical procedures among patients with NVE due to CoNS, the mortality rates among patients with NVE due to CoNS and among patients with NVE due to S. aureus were similar (32 patients [25%] and 124 patients [27%], respectively; P=.44); the mortality rate among patients with NVE due to CoNS was higher than that among patients with NVE due to viridans group streptococci (24 [7.0%]; P=.01). Persistent bacteremia (odds ratio, 2.65; 95% confidence interval, 1.08-6.51), congestive heart failure (odds ratio, 3.35; 95% confidence interval, 1.57-7.12), and chronic illness (odds ratio, 2.86; 95% confidence interval, 1.34-6.06) were independently associated with death in patients with NVE due to CoNS (c index, 0.73). CONCLUSIONS: CoNS have emerged as an important cause of NVE in both community and health care settings. Despite high rates of surgical therapy, NVE caused by CoNS is associated with poor outcomes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
