The study aimed to identify the risk factors of intravenous immunoglobulin (IVIG) unresponsiveness from the initial clinical parameters of the Taiwanese KD patients. Methods: We enrolled 248 KD (development dataset: 181, validation: 67) patients who received IVIG within 10 days after fever onset. IVIG unresponsiveness was defined by persistent fever beyond 24 hours after IVIG or recrudescent fever with KD symptoms. Results: From the development dataset (181 patients), IVIG unresponsiveness was noted in 22 patients (12.1%). The preIVIG levels of albumin, percentage of neutrophils, and positive lymphadenopathy were identified with highest risk for IVIG unresponsiveness. These three variables were used to construct a three-variable logistic regression model, which yielded an area under the receiver-operating-characteristics curve of 0.87. These three variables were further used to generate a composite scoring model (Formosa score) which yielded a sensitivity of 90.9% and specificity of 81.3% for a cut-off point of three or more. Validation in an independent cohort (67 KD patients) yielded sensitivity and specificity of 71.4% and 81.0%, respectively. Conclusion: We have established a simple three-variable Formosa score for KD patients to identify early those at risk of IVIG unresponsiveness for timely aggressive immunomodulation initially. ? 2015.[SDGs]SDG3albumin; immunoglobulin; albuminoid; C reactive protein; immunoglobulin; Article; child; female; fever; Formosa score; human; lymphadenopathy; major clinical study; male; mucocutaneous lymph node syndrome; neutrophil; risk factor; scoring system; sensitivity and specificity; Taiwanese; treatment response; drug resistance; fever; infant; lymphadenopathy; mucocutaneous lymph node syndrome; multivariate analysis; preschool child; receiver operating characteristic; retrospective study; risk factor; severity of illness index; statistical model; Taiwan; treatment failure; validation study; Albumins; C-Reactive Protein; Child, Preschool; Drug Resistance; Female; Fever; Humans; Immunoglobulins, Intravenous; Infant; Logistic Models; Lymphadenopathy; Male; Mucocutaneous Lymph Node Syndrome; Multivariate Analysis; Retrospective Studies; Risk Factors; ROC Curve; Sensitivity and Specificity; Severity of Illness Index; Taiwan; Treatment Failurejournal article10.1016/j.jfma.2015.03.012259109312-s2.0-84928036586
