Dengue Fever Clinical Trial
Official title:
Laboratory Diagnosis and Prognosis of Severe Dengue
A study of dengue in children presenting to outpatient departments of 5 large hospitals in
Ho Chi Minh City and Tien Giang province, Viet Nam.
Different blood tests are compared at the early stages of dengue fever onset in their
ability to accurately and specifically detect children whose dengue will progress to severe
disease.
In a prospective study in the outpatients department of three large hospitals in Ho Chi Minh
City, Viet Nam, we will determine the early diagnostic sensitivity, specificity, positive
and negative predictive values of two NS1 diagnostic tests in severe dengue cases.
The study is intended to develop a prognostic algorithm for the early identification of
severe dengue cases.
Routine demographic, haematological and biochemical laboratory markers will be utilized to
derive a prognostic algorithm that is clinically-useful for guiding patient triage and
interventions.
We hope to discover and evaluate new early biomarkers of severe dengue and will evaluate
candidate host response molecules and virological markers for their prognostic value.
We further plan to understand the phylogeography of DENV in the super-urban setting of HCMC.
We will use genome scale sequencing of DENV together with geospatial information on the
residential addresses of patients to better understand transmission dynamics in space and
time in a high transmission super-urban district of HCMC and thereby identify opportunities
for public health interventions.
