Abstract |
Purpose : Kawasaki disease is notorious for coronary arterial complication which is usually developed as a febrile disease in early childhood. Increased polymorphonucleus(PMN) cell levels in acute phases may be associated with the pathophysiology of Kawasaki disease. We studied the relationship between coronary arterial dilatation and elastase activity which was excreted from PMN cell and roles as an important factor for vasculitis.
Methods : Ten patients diagnosed with Kawasaki disease in Yonsei University Medical Center were examined between November, 2001 and January, 2002. In addition, 15 patients with other febrile diseases were also examined. Echocardiography was done in patients with Kawasaki disease on the first day of admission and four weeks after the onset of the disease. At each time, venous samples were drawn and separated into plasma and leukocytes. In patients with other febrile disease, samples were drawn on admission. Elastase activities in plasma and neutrophil extracts were measured.
Results : The significant increased plasma elastase activity, 6.19?.74 U/mL, found in Kawasaki disease patients compared with the other febrile disease patients, 4.86?.17 U/mL(P<0.05). And there was no significance between the above two diseases in terms of the elastase activity in neutrophil extracts. The relationship between initial elastase activity and the coronary arterial complication which was shown in subacute phase wasn't significant.
Conclusion : Plasma elastase activity was increased in Kawasaki disease significantly, but the initial plasma elastase activity in the acute phase could not reflect the range of coronary arterial complication. |
