Kawasaki disease and oxidative metabolism.
The plasmid lipid peroxidation products: malonyldialdehyde (MDA), organic hydroperoxides (OHP) and zinc peripheral values were analysed in seven children with Kawasaki disease, in the acute phase, before and after treatment with intravenous immunoglobulins. In the acute phase, plasma levels of MDA (2.95 +/- 0.30 mumol/l, control group: 2.52 +/- 0.08 mumol/l) and OHP (235 +/- 65 mumol/l, control group: 120 +/- 10) were increased (p less than 0.05 and p less than 0.01). Moreover, plasma zinc levels were significantly decreased (10 +/- 2.15 mumol/l versus 15.6 +/- 2.5 mumol/l in control group, p less than 0.05). After treatment with immunoglobulins, MDA, OHP and plasma zinc levels returned to normal. The parallel normalisation of clinical injury draws attention to the possible role of oxygen intermediates in connective tissue degradation and in the pathogenesis of vascular abnormalities in Kawasaki disease.
