AbstractYılmazer MM, Özdemir R, Meşe T, Küçük M, Öner T, Devrim İ, Bayram N, Güven B, Tavlı V. Kawasaki disease in Turkish children: a single center experience with emphasis on intravenous immunoglobulin resistance and giant coronary aneurysms. Turk J Pediatr 2019; 61: 648-656. Prompt diagnosis and the administration of intravenous immunoglobulin (IVIG) has reduced the incidence of coronary artery abnormalities (CAA) in Kawasaki Disease (KD). The resistance to treatment and development of the coronary sequelae remain the most important problems in KD. We aimed to determine the predicting factors of nonresponse to initial IVIG therapy and to analyze the cases who had giant coronary aneurysms. A total of 120 KD cases, including 61 children fulfilling the criteria for KD and 59 with incomplete KD were enrolled into this study. Demographic, laboratory, clinical, echocardiographic characteristics, and treatment regimens were reviewed, retrospectively. The median age of the patients was 33.5 months (range: 3-168 months). Coronary artery aneurysms were detected in 35 patients (29%) at the time of diagnosis. Twenty-eight patients had coronary aneurysms small or medium in size, one had a large, and seven had giant coronary aneurysms. CAA persisted in 8 cases in the follow-up, all of which were large or giant aneurysms. A ten month-old girl with a giant coronary aneurysm was referred to coronary bypass surgery in the subacute phase of follow-up, due to myocardial ischemia. Eighteen patients were unresponsive to the initial IVIG therapy (%15), of whom 10 were diagnosed as cKD and 8 were iKD. Patients who did not respond to initial IVIG therapy, had higher white blood cell (WBC) count, higher C-reactive protein (CRP) and lower albumin levels than those who did (P < 0.05). In univarite analysis; CRP, WBC and albumin were found to be significant predictors of nonresponse to initial IVIG therapy, while a stepwise multiple linear regression analysis showed that WBC count and albumin levels were significantly correlated with nonresponse to initial treatment with IVIG. Our study showed that WBC count and albumin levels might be used as predictors of nonresponse to the IVIG therapy in Turkish children with KD.
