1/1. 'culture-negative' prosthetic valve endocarditis. Hazards of postoperative steroid therapy for unexplained fever.Two patients had prolonged unexplained fever along with multiple negative blood cultures after cardiac valve replacement surgery. Following the administration of corticosteroids for presumed postpericardiotomy syndrome, both patients improved symptomatically and defervesced, only to have positive blood cultures for staphylococcus epidermidis shortly thereafter.
