Non-HACEK gram-negative bacillus endocarditis.

Journal Article (Academic Article)

BACKGROUND: Infective endocarditis caused by non-HACEK (species other than Haemophilus species, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, or Kingella species) gram-negative bacilli is rare, is poorly characterized, and is commonly considered to be primarily a disease of injection drug users. OBJECTIVE: To describe the clinical characteristics and outcomes of patients with non-HACEK gram-negative bacillus endocarditis in a large, international, contemporary cohort of patients. DESIGN: Observations from the International Collaboration on Infective Endocarditis Prospective Cohort Study (ICE-PCS) database. SETTING: 61 hospitals in 28 countries. PATIENTS: Hospitalized patients with definite endocarditis. MEASUREMENTS: Characteristics of non-HACEK gram-negative bacillus endocarditis cases were described and compared with those due to other pathogens. RESULTS: Among the 2761 case-patients with definite endocarditis enrolled in ICE-PCS, 49 (1.8%) had endocarditis (20 native valve, 29 prosthetic valve or device) due to non-HACEK, gram-negative bacilli. Escherichia coli (14 patients [29%]) and Pseudomonas aeruginosa (11 patients [22%]) were the most common pathogens. Most patients (57%) with non-HACEK gram-negative bacillus endocarditis had health care-associated infection, whereas injection drug use was rare (4%). Implanted endovascular devices were frequently associated with non-HACEK gram-negative bacillus endocarditis compared with other causes of endocarditis (29% vs. 11%; P
