PROPIONIBACTERIUM ACNES PROSTHETIC VALVE ENDOCARDITIS

Chronic prosthetic valve endocarditis due to Propionibacterium acnes: an unexpected cause of prosthetic valve dysfunction.

INTRODUCTION AND OBJECTIVES To determine the characteristics of Propionibacterium acnes prosthetic valve endocarditis (PAPVE). METHODS Prospective descriptive study of 16 consecutive cases of PAPVE. RESULTS Seven patients developed PAPVE early and 9 developed it late. In all those who developed PAPVE late, there was a history of mucocutaneous barrier manipulation. The delay in diagnosis was...

Propionibacterium acnes prosthetic valve endocarditis with abscess formation: a case report

BACKGROUND Endocarditis due to Propionibacterium acnes is a rare disease. Scant data on treatment of these infections is available and is based on case reports only. If the disease is complicated by abscess formation, surgical intervention combined with an antibiotic therapy might improve clinical outcome. In some cases, cardiac surgeons are reluctant to perform surgery, since they consider the...

Quantification of the antibody response to Propionibacterium acnes in a patient with prosthetic valve endocarditis: – a case report

BACKGROUND The isolation of Propionibacterium acnes in blood cultures is often considered a contaminant. On rare occasions, P. acnes can cause severe infections, including endocarditis and intravascular prosthesis-associated infections. To evaluate the discrimination between a contaminant and a clinically relevant infection we used an Ouchterlony test system to quantify the antibody response to...
