Prosthetic valve endocarditis in melioidosis. Case report

Abstract

Melioidosis is an endemic disease to several regions and occurs predominantly in Southern Asia, Northern Australia, China and Taiwan. In South America, Colombia is second after Brazil in number of melioidosis cases reported. Clinical manifestation varies from asymptomatic infection to multiorgan compromise involving multiple abscesses and septic shock. Cardiac compromise is infrequent, with an incidence of < 1%. We report the case of a 51-year-old patient from Colombia with a mechanical aortic valve who had an abscess in right leg and in the prosthetic valve. Burkholderia pseudomallei was isolated in blood cultures and drained pus from the leg cultures. Patient was treated with meropenem and cotrimoxazole and required aortic valve replacement, resulting in adequate improvement in clinical symptoms.
