About

A case-control cohort study is being conducted to develop and validate the performance of a whole blood gene expression qPCR test to distinguish KD from other febrile conditions by collecting whole blood sample from KD patients in the first 7 days of illness and from febrile controls immediately after presentation and before clinical diagnosis is confirmed.

Full description

Currently, there is no diagnostic tool for Kawasaki disease (KD). Diagnosis is based on clinical features shared with other febrile conditions, frequently resulting in delayed or missed treatment and an increased risk of coronary artery aneurysms. An accurate diagnostic blood test might enable early discrimination of Kawasaki disease from other infectious and inflammatory conditions, resulting in a precise clinical treatment to improves survival and quality of children's life. The purpose of this study is to develop and validate a blood-based assay for accurate diagnosis of KD in in the first 7 days of illness.

The study will collect blood samples from healthy patients with no recent history of fever or immunization and from febrile patients diagnosed with KD or other infectious and inflammatory diseases.

Three types of patients in this study:

Cohort A:

Children ages 6-60 months old who have been diagnosed with (or strong clinical suspicion for) KD by clinician. Blood samples must be collected before any treatment has been initiated.

Cohort B:

Children ages 6-60 months old with febrile conditions who have been diagnosed with other infections or inflammation by clinician. Blood samples must be collected before any treatment.

Cohort C:

Children ages 6-60 months old with no recent history of fever or immunization.
