Abstract
Purpose
We undertook this study to investigate discrepancies in C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) values, and variations following intravenous immunoglobulin (IVIG) therapy in Kawasaki disease (KD).
Methods
A total of 123 KB patients were retrospectively enrolled. Patients were treated with IVIG 2 g/kg at 2 to 9 days after disease onset. We obtained white blood cell (WBC) count, percentage of neutrophils (% neutrophils), CRP, ESR, and N-terminal pro-brain natriuretic peptide (NT—proBNP) values before and 48 to 72 hours after IVIG treatment. Discrepancy was defined as CRP 210 mg/dL and ESR <50 mm/ hr (Group 1), 0r CRP <10 mg/dL and ESR 250 mm/hr (Group 2).
Results
Thirty-six of 123 subjects (29.2%) had a discrepancy: 25 (20.3%) in Group 1 and 11 (8.9%) in Group 2. In Group 1, 15 patients (60%) had fever for <5 days (early presenter) and 10 (40%) had fever for 25 days (late presenter). There were six early presenters (55%) and five late presenters (45%) in Group 2. Late presenters had higher ESR than early presenters (34.31210 mm/hr vs. 26.3:193 mm/hr, P=0.029). After IVIG treatment, elevated WBC count, % neutrophils, CRP, and NT—proBNP levels normalized. In contrast, ESR increased from 37_4i21_9 mm/hr t0 48.0i22.7 mm/hr (n=36, P:0.0S1).
Conclusions
A discrepancy may be related to the duration of fever. Due to discrepancies in CRP and ESR values in acute KD, both should be measured to assess the degree of inflammatory activity before |V|G treatment. After IVIG treatment, the ESR should not be used as a marker of response to therapy in KD.
