Non-HACEK Gram-negative bacillus endocarditis.

Abstract Patients and methods Retrospective analysis of clinical data using 26 diagnosed non-HACEK Gram-negative infective endocarditis cases from nine hospitals in Turkey. Results Mean age of patients was 53 (28–84) years, with a 23% case fatality. Nineteen (73%) of the 26 patients had at least one predisposing factor. The presence of a central venous catheter was the most common predisposing factor (7/26 patients). Pseudomonas aeruginosa (7/26 patients) and Escherichia coli (7/26 patients) were the most common pathogens. The median duration of the antibiotic therapy was 42 days (range 3–84 days). Surgical procedures were performed in 10 patients. The case fatality was similar in patients who did or did not undergo surgery (20% vs. 25%).
