Abstract

A retrospective study was performed on culture-positive patients (n = 57) with melioidosis presenting to the Townsville Hospital to define the epidemiology of the disease in Queensland, Australia. Mortality was 25% (n = 14) with a 9% (n = 5) relapse rate. At presentation, primary organs involved included the lungs (58%; n = 33), genitourinary system (11%; n = 6), skin and soft tissue (9%; n = 5), bone and joints (4%; n = 2), central nervous system (4%; n = 2), mycotic aneurysm (2%; n = 1) and peritonitis (2%; n = 1). No focus of infection could be identified in 12% of cases (n = 7). There was no significant difference in the clinical presentation of melioidosis in Queensland compared with the Northern Territory. Regional trends in the clinical presentation of melioidosis in Australia compared with Southeast Asia were confirmed. Risk factors for disease included diabetes (42%), excess alcohol consumption (42%), chronic lung disease (26%), immunosuppressive drug use (12%), renal disease (11%), malignancy (7%) and autoimmune disease (5%). No risk factors were identifiable in 18% of cases. The presence of multiple risk factors for melioidosis was not significantly associated with increased mortality (P > 0.05).
