Abstract | PURPOSE: SUMMARY: A 48-year-old man with significant comorbidities was admitted to our institution with complaints of malaise, shortness of breath, and vague persistent pain. He was diagnosed with S. lugdunensis infective endocarditis and was treated with cefazolin continuous infusion for 10 days without resolution of bacteremia. As surgical intervention was deemed inappropriate, rifampin was added to the treatment regimen for its antibiofilm activity. After rifampin initiation, resolution of bacteremia was rapidly achieved. Subsequent blood cultures remained negative, and the patient was discharged home in stable condition to complete six weeks of i.v. cefazolin and rifampin therapy. The patient continued treatment, as documented by the infusion center, weekly for five weeks. The patient was rehospitalized during his sixth week of treatment due to impending respiratory failure, whereupon he was intubated and admitted to the intensive care unit. The patient's cardiac status gradually worsened over the following days, and he ultimately died. Blood cultures from days 1 and 2 of hospitalization revealed no bacterial growth at five days. CONCLUSION:
Cefazolin and rifampin therapy in a hospitalized patient with bacteremia and aortic valve endocarditis caused by S. lugdunensis resulted in rapid eradication of the bacteremia. After more than five weeks of cefazolin- rifampin treatment, the patient was rehospitalized with worsening cardiac function and died. Blood cultures during the second admission were negative.
