Abstract 76: Clinical Usefulness Of Serum Procalcionin Level In Kawasaki Disease Children.

Purpose: Procalcitonin (PCT) is one of acute phase reactants such as C-reactive protein (CRP), and is likely to elevate in systemic inflammation, especially bacterial infection. As we know, the CRP level rise in the patients with high fever including Kawasaki disease (KD) and bacterial infection. So we investigated the clinical usefulness of serum PCT level in Kawasaki disease (KD), which is a systemic inflammation caused by vasculitis. Method: From August 2013 to June 2014, a total 336 patients were studied serum PCT level during hospitalization. We enrolled 41 patients of KD, 83 patients with viral infection, and 21 patients with bacterial infection. Result: The patients with KD had significantly higher mean age (24.4±18.1 months), mean body weight (12.1±3.9 Kg), and mean duration of fever prior to admission (4.4±1.8 days) than other patients (p Conclusion: Serum PCT level may help to differentiate KD from viral infection, but we did not find a significant difference in PCT level between KD and bacterial infection. And the utility of PCT level as clinical marker in KD may be limited.
