title: Epstein-Barr virus antibodies in Kawasaki disease.
abstract: The prevalent ages at onset for Kawasaki Disease (KD) and Epstein-Barr virus (EBV) infection are known to be similar in Korea and Japan. We evaluated the correlation between EBV infection and KD. The antibodies to EBV such as anti-viral capsid antigen (VCA) IgG and IgM, anti-diffuse and restricted early antigen IgG (anti-EADR IgG), and the anti-EBV determined nuclear antigen IgG (anti-EBNA IgG) were examined in 29 KD patients at five separate times sequentially during a period of one year, and also in 14 other children with a past history of KD. The results of each group were compared with those of age-matched controls. The positive rates of anti-VCA IgG and IgM at presentation in the KD patients were 41.4% (12/29) and 0% (0/29), respectively. Only one patient was found to be anti-VCA IgM-positive within two months. There were no cases of anti-VCA IgG except one, anti-EADR IgG and anti-EBNA IgG positive to negative seroconversion during the year. The children with a past history of KD showed higher anti-EBNA IgG-positive rates than the controls (p=0.04). There was no difference in the seropositive rates of the antibodies to EBV, cytomegalovirus, herpes simplex virus and herpes zoster virus. In conclusion, children with KD were noted to have normal immune responses to EBV infection. Children with a past history of KD seemed to be infected with EBV at a later age than children with no history of KD.
