What is the treatment approach for Streptococcus bovis endocarditis?

Streptococcus bovis endocarditis is associated with significant implications for the patient's health, particularly concerning an underlying malignancy. The treatment approach involves both antibiotic prophylaxis and careful evaluation for colon cancer because S. bovis bacteremia and endocarditis can be a marker for colorectal cancer, especially in older adults.

Prophylaxis with penicillin is indicated prior to certain procedures in patients at risk for endocarditis, including those with a history of valvular heart disease or previous endocarditis. Alongside this, patients diagnosed with S. bovis endocarditis should undergo a thorough investigation, including colonoscopy, to rule out colorectal malignancy, as the presence of this organism in the bloodstream or heart valves is often related to abnormalities within the colon.

Thus, the approach encompasses both the administration of penicillin prophylaxis to prevent further infection and the evaluation for colon cancer to address the potential underlying pathology contributing to the endocarditis. This comprehensive strategy ensures both immediate treatment and long-term health considerations for the patient.
