The predictors of severe disease or death were determined for 85 melioidosis patients in Kuala Lumpur, Malaysia. Most of the patients were male, > 40 years old, and diabetic. Severe disease or death occurred in 28 (32.9%) cases. Lower lymphocyte counts and positive blood cultures were significant independent predictors of severe disease, but age, presentations with pneumonia, inappropriate empirical antibiotics, or flagellin types of the infecting isolates were not. Knowledge of local predictors of severe disease is useful for clinical management.
This is a report of the first recognized case of melioidosis in Nepal. Illness began 1 month after returning from Malaysia after a 1 y stay. The case highlights the importance of ascertaining the travel history in any patient with a suspected infectious disease in this age of global travel.
A report is presented of seven patients with acute septicaemic melioidosis seen at the University Hospital, Kuala Lumpur, Malaysia, during 1976-1979. All had associated disorders which rendered them more susceptible to infection. As prognosis depends on early diagnosis it is important that this disease be considered in the differential diagnosis of a septicaemic illness in such patients from endemic areas. The treatment of choice is a combination of tetracyclines and chloramphenicol, initially used in massive doses, and continued for at least six month to prevent relapses.
Burkholderia pseudomallei (B. pseudomallei) has been shown to persist intracellularly in patients with melioidosis, until reactivated by decreasing immunocompetence. We have previously demonstrated by transmission electron microscopy, the internalisation of B. pseudomallei by human macrophages and the occurrence of phagosome-lysosome fusion.
A neglected tropical disease, melioidosis is known to have variability in clinical presentations. Here, we described clinical features that should alert the physicians on the possibility of melioidosis. In this review of 86 cases from 2001 to 2011, the common presentations of melioidosis in the Emergency Department (ED), Hospital Universiti Sains Malaysia were; male gender (79.1 %), in working age group (47.8 ± 15.2 year-old), worked in contact with soil (73.3 %), presented with fever (91.9 %), in rainy season (55.8 %), have underlying diabetes mellitus (79.1 %), have leukocytosis (67.4 %) and high blood glucose (62.8 %) during presentation. In 34.9 % of cases, the antimicrobials were initiated at the ED and only 10.5 % include antimelioid drugs. Thirty-one patients (36.0 %) died due to melioidosis and 51.6 % of this were within 48 h of admission. Despite high mortality rate, the clinical awareness on the possibility of melioidosis among emergency physicians is still low and need to be strengthened.
