| Abstract |
Purpose
: High dose intravenous immunoglobulin(IVIG) therapy is effective in reducing the
incidence of coronary artery aneurysm in Kawasaki disease(KD) patients, however, the precise
mechanisms by which IVIG reverses the immune activation is unknown.
Methods
: The sera and peripheral mononuclear cells(PBMCs) were obtained from 10 KD patients
in the acute stage(24 hrs before) and 24 hrs after one dose of IVIG(2g/kg) treatment. We
measured serum interleukin 6(IL-6) and tumor necrosis factor α(TNF-α) and compared them to
the messenger RNA expression of the PBMCs by reverse transcription polymerase chain reaction.
We also investigated the cytokines’ or immunoglobulins’ production of PBMCs which were
stimulated with phytohemagglutinin-P(PHA-P) or pokeweed mitogen(PWM, without in vitro IVIG
treatment) by enzyme-linked immunosorbent assay.
Results
: The serum levels of IL-6 and TNF-α decreased significantly after IVIG treatment.
However, the gene expression of IL-6 and TNF-α showed no significant difference after IVIG
treatment. IL-6 and TNF-α productions of PBMCs stimulated with PHA-P decreased significantly
after IVIG treatment, however, IL-4 and IFN-γ production showed no significant differences.
IL-6 production of PBMCs stimulated with PWM also decreased significantly after IVIG
treatment, but TNF-α did not change significantly. The synthesis of IgG, IgM, IgA and IgG1
after IVIG treatment showed a significant decrease, and that of IgG2 showed a slight decrease,
but was not statistically significant.
Conclusion
: The results demonstrate that the administration of IVIG in the acute stage of KD
resulted in the alterations of activated immunologic abnormalities, especially in monocytes and B
cells. |
