Although in Japan several risk scoring systems are able to predict patients with IVIG-resistant (KD), they do not accurately predict non-responders in other regions. Aim: The objectives of this study were to determine the predictors of IVIG resistance and coronary artery aneurysm (CAA) and to develop risk scoring systems for predicting IVIG-resistant KD in the Thai population. Methods: A total of 217 patients with KD between 2004 and 2014 were retrospectively reviewed. All patients including 116 with complete KD and 101 with incomplete KD were diagnosed and treated with 2 g/kg IVIG. Results: Twenty-six patients (85% male) with IVIG-resistant KD had a reduced platelet count and increased neutrophil-to-lymphocyte ratio compared with those with an IVIG response. Fifty-five patients with CAA eight weeks after diagnosis had a longer duration of fever (≥8 days) and increased platelet count (≥550 × 109/L) than those with non-CAA. Based on analysis by multivariate logistic regression, haematocrit ≤30%, platelet count ≤300 × 109/L, aspartate aminotransferase ≥40 U/L and neutrophil-to-lymphocyte ratio ≥3.2 were predictors of IVIG resistance. The new scoring system using these significant factors had a sensitivity of 80.8% and a specificity of 66.8% in identifying patients with IVIG resistance. Japanese scoring systems had low sensitivity and specificity. Conclusions: KD patients with reduced mean haemoglobin, increased AST level, increased neutrophil-to-lymphocyte ratio and reduced platelet count should be considered for conjunctive therapy such as a corticosteroid in combination with standard treatment. Duration of fever ≥8 days and platelet count ≥550 × 109/L were predictors of CAA. To prevent cardiovascular complications, patients should be treated promptly after KD has been diagnosed. 2018-09-05T04:35:03Z 2018-09-05T04:35:03Z 2018-05-17 Journal 20469055 20469047 2-s2.0-85047107957 10.1080/20469047.2018.1471381 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85047107957&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/58918 |
