    Abstract:
    BACKGROUND AND OBJECTIVE: It is well-known the relationship between Streptococcus bovis (S. bovis) bacteremia and colon cancer, liver cirrhosis and others neoplasms. However, a study protocol to rule out these underlying diseases has not been carried out yet. Our objective was to describe S. bovis bacteremia and associated diseases. PATIENTS AND METHOD: Multicenter, retrospective cohort study. S. bovis bacteremias episodes between 2001 and 2009 were included. Mean variables: colon neoplasm, non-colonic neoplasm or liver cirrhosis. Epidemiologist aspects, bacteremia related variables, personal and familiar history and clinical and analytical data were collected. RESULTS: Ninety three patients were included. One out of four individuals had a colon neoplasm. Fifty seven per cent were concomitant cases with bacteremia and six cases were diagnosed after bacteremia (time bacteremia-diagnosis of neoplasm [months], median [Q1-Q3], 2.6 [1-11]). Fourteen (15%) patients were diagnosed with any non-colonic neoplasm (mainly biliary and pancreatic [6 cases] or esophagus-gastric [3 cases]). There were three patients (21%) with concomitant bacteremia non-colonic neoplasm and two after it (1.2 and 10.4 months). Twenty-one (23%) patients suffered from liver cirrhosis. CONCLUSIONS: Patients with S. bovis bacteremia must undergo a study designed to rule out underlying diseases. We suggest that this study should include: a colonic evaluation, ideally by colonoscopy, a liver evaluation by serum chemistry, an abdominal ultrasound scan or a method of liver fibrosis assessment, a gastroscopy and an evaluation of biliary and pancreatic areas by magnetic resonance imaging.
