Adapting LFI for Melioidosis

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03528265
Recruitment Status : Completed

Brief Summary:
Towards the goal of reducing melioidosis, this study will help clinicians in Sarawak to diagnose and understand the causes and risk factors for melioidosis. The data will help the clinicians to provide faster test results and better clinical care. The investigator's laboratory efforts will supplement available diagnostics by adding a new, easier-to-use test involving lateral flow immunoassay to rapidly detect Burkholderia pseudomallei, a bacterium causing melioidosis. The study aims to study up to 400 patients with melioidosis-like symptoms who are admitted to Kapit Hospital, Sarawak, Malaysia. No participants will be enrolled from other sites. The study will also examine the demographic, behavioral and occupational risk factors associated with hospital admissions to understand any existing associations between these variables and melioidosis prevalence.

Group/Cohort Intervention/treatment
Patients with melioidosis-like symptoms admitted to Kapit Hosp Device: Lateral flow immunoassay
Biospecimens of patients with melioidosis-like symptoms will be tested with lateral flow immunoassay to detect Burkholderia pseudomallei, bacterium causing melioidosis

Primary Outcome Measures :
  1. Proportion of true positive [ Time Frame: up to 5 weeks ]
    Proportion of true positive of Bukholderia pseudomallei using rapid diagnostic tests compared to the results of qPCR, bacterial culture and Gram stain

  2. Proportion of true negative [ Time Frame: up to 5 weeks ]
    Proportion of true negative of Bukholderia pseudomallei using rapid diagnostic tests compared to the results of qPCR, bacterial culture and Gram stain

Secondary Outcome Measures :
  1. Statistical association between risk factors and test results [ Time Frame: up to 3 months ]
    conduct a survey to determine a statistical association between clinical risk factors and the test results combined

Biospecimen Retention:   Samples With DNA
DNA from blood samples
