Abstract
BACKGROUND: Looking for and treating the portal of entry (POE) of infective endocarditis (IE) is important, but published research on this topic is nonexistent. OBJECTIVES: The goal of this study was to systematically search for the POEs of present and potentially new episodes of IEs. METHODS: Patients were systematically seen by a stomatologist, an ear, nose, and throat specialist, and a urologist; women were systematically seen by a gynecologist; patients were seen by a dermatologist when there were cutaneous and/or mucous lesions. Colonoscopy and gastroscopy were performed if the microorganism came from the gastrointestinal tract in patients ≥50 years of age and in those with familial histories of colonic polyposis. Treatment of the POE was systematically considered. RESULTS: The POEs of the present IE episodes were identified in 74% of the 318 included patients. The most frequent POE was cutaneous (40% of identified POEs). It was mainly (62% of cutaneous POEs) associated with health care and with intravenous drug use. The second most frequent POE was oral or dental (29%). A dental infectious focus was more often involved (59% of oral or dental POEs) than a dental procedure (12%). POEs were gastrointestinal in 23% of patients. Colonic polyps were found in one-half of the patients and colorectal adenocarcinomas in 14%. Performance was good regarding the search for an oral or dental or a colonic potential POE, which were found in 53% and 40% of patients, respectively. CONCLUSIONS: Our search for the POEs of present IEs was often successful, as was searching for an oral or dental or a gastrointestinal POE of a new IE episode. We advise the systematic performance of stomatologic examinations in patients with IE and performance of colonoscopy in patients ≥50 years of age or at high risk for colorectal cancer.
