Abstract
-
PURPOSE: Epidemiologic evidence suggests an infectious cause for Kawasaki disease(KD), but
the etiology of KD remains unknown. The aim of this study was to determine whether viral
infections are related in the pathogenesis of KD by detecting viral genomes using nested
polymerase chain reaction.
METHODS
Peripheral blood was obtained from 18 acute KD patients before administration of
intravenous gamma globuline and 11 age-matched control patients. DNA extraction from whole
blood was performed using proteinase K and phenol. The primer sequences were derived frorn
UL-42 for herpes simplex virus type 1(HSV-1), US-4 for herpes simplex virus type 2(HSV-2),
major IE for cytornegalovirus(CMV) and IR1 for Epstein-Barr virus(EBV). Two successive PCR
were performed, and the PCR products were detected by agarose gel electrophoresis.
RESULTS
HSV-1-PCR was negative in both groups and HSV-2-PCR was positive in 2 of 17 of the
KD group. CMV-PCR was positive in 1 of 11 in the control group and all negative in the KD
group. EBV-PCR was positive in 7 of 18(39%) of the KD group and in 2 of 11(18%) of the control
group. EBVCA-IgM was negative in all 5 EBV-PCR positive patients, but EBVCA-IgG, EBNA and
EBEA was positive in 1 EBV-PCR positive patient.
CONCLUSION
This study suggests that an unusual EBV-cell interaction may exist in Kawasaki
disease.
