A 55-year-old man with a metallic aortic valve and MRSA prosthetic valve endocarditis has completed 6 weeks of IV Vancomycin plus Rifampicin plus Gentamicin. He is clinically well. Blood cultures are sterile. CRP has normalised. Is ongoing oral suppressive antibiotic therapy needed after completing the standard course?

Correct answer: E — Not routinely — if the PVE was treated with surgery (valve replacement) and adequate antibiotics with documented cure (sterile cultures, normalised CRP, no complications on imaging), no further antibiotics are needed; if treated medically without surgery, some experts consider long-term suppression

After successfully treated PVE with valve replacement surgery and adequate antibiotic course (6+ weeks, documented culture clearance, normalised inflammatory markers), ongoing suppressive therapy is NOT routinely recommended. Follow-up includes: clinical assessment, repeat bloods (CRP, blood cultures) at 1 and 3 months post-treatment, and echocardiographic surveillance. For medically treated PVE without surgery (rare, higher relapse risk), some experts consider prolonged oral suppression — this is a case-by-case MDT decision.
