RESUMO
There is a well-established association between Streptococcus bovis bacteremia (SBB) and colorectal cancer. However, SBB is also frequently associated with chronic liver disease and has been described with other gastrointestinal disorders. The aim of the study was to evaluate the prevalence of gastrointestinal disease in patients with SBB. Retrospective analysis of the microbiology database at Jackson Memorial Medical Center, Miami, Florida, between 1992 and 2002, was performed. Patients' clinical records were reviewed, with special focus on underlying gastrointestinal disease or other major comorbidities. Thirty-eight patients (83%) were adults and eight (17%) were pediatric patients. Nineteen patients presented with gastrointestinal disorders associated with SBB (41%). Nine adult patients (19%) had end-stage liver disease (five female). Six patients had alcohol-induced liver disease (one with concomitant chronic hepatitis C), with the remaining three cases related to autoimmune hepatitis, primary biliary cirrhosis, and nonalcoholic steatohepatitis. Colonic neoplasms (adenocarcinoma in 3 and adenomatous polyps in 3) were found in 6 of 10 adult patients in whom colonoscopic evaluation was performed. Seven adult patients had acquired immunodeficiency syndrome (AIDS) (18%). Mortality in the patients with AIDS and SBB was high (71%). No significant association with gastrointestinal diseases was found in the pediatric population. Bacteremia due to S. bovis in adults is frequently associated with hepatic dysfunction (1:4), colonic neoplasms (1:6), and AIDS (1:6). This association was valid for our adult population only. SBB is an early clue to the likely presence of these serious underlying conditions and warrants rigorous investigation when recognized.

Wireless capsule endoscopy is an exciting and innovative technology that allows direct visualization of areas of the small bowel that were previously inaccessible to the "umbilicated" endoscope except during intraoperative enteroscopy. The wireless capsule endoscope permits noninvasive small bowel endoscopy in the ambulatory setting and has been proven to be a significant advance in the evaluation of patients with challenging small intestinal disease.
