Background: The risk of allergic diseases among Kawasaki disease (KD) patients relative to the general population is not known. The aim of this study was to perform a population-based cohort study to investigate the risk of allergic diseases among children after KD in Taiwan- a country with the third highest incidence of KD in the world.Methods: Data were obtained from the Taiwan National Health Insurance Research Database. In total, 253 patients who were 5 years of age or younger and had a first-time hospitalization with a diagnosis of KD between 1997 and 2005 were included as the study cohort and 1,012 non-KD patients matched for age and sex were included as comparison cohort. Multivariate Cox proportional hazard regression model was used to adjust for confounding and to compare the 6-year allergic-free survival rate between these two cohorts.Results: The incidence rate of allergic diseases (184.66 per 1000 person-year) was significantly higher in the KD cohort than in the control cohort (124.99 per 1000 person-years). After adjusting for potential confounders, the adjusted hazard ratios of asthma and allergic rhinitis were 1.51 (95% confidence interval = 1.17-1.95) and 1.30 (95% confidence interval = 1.04-1.62), respectively.Conclusion: We conclude that KD patients were at an increased risk for allergic diseases compared with the comparison cohort. © 2013 Kuo et al.; licensee BioMed Central Ltd.

Background:Kawasaki disease (KD) is a systemic vasculitis of unknown etiology. Thymus and activation-regulated chemokine/chemokine ligand 17 (TARC/CCL17) is one of the Th2 chemokines and has been suggested as a candidate gene for conferring susceptibility to Th2 associated with allergy diseases. This study examined the correlation between gene polymorphisms and plasma levels of TARC/CCL17 in patients with KD and the outcomes of KD.Methods:A total of 381 KD patients and 564 controls were subjected to determination of five tagging single-nucleotide polymorphisms of TARC/CCL17. In addition, plasma TARC/CCL17 levels were measured by enzyme-linked immunosorbent assay.Results:Polymorphisms of TARC/CCL17 were significantly different between normal children and patients with KD. A allele of rs4784805 has better intravenous immunoglobulin (IVIG) treatment response to KD. Furthermore, plasma TARC/CCL17 levels were higher in KD patients than that in controls before IVIG treatment. After IVIG treatment, plasma TARC/CCL17 levels decreased significantly.Conclusion:This study provides the first evidence supporting the association between TARC/CCL17 polymorphisms, susceptibility of KD, and IVIG responses in KD patients. © 2013 International Pediatric Research Foundation, Inc.

Elevation of serum IgE levels has long been associated with allergic diseases. Many genes have been linked to IgE production, but few have been linked to the developmental aspects of genetic association with IgE production. To clarify developmental genetic association, we investigated what genes and gene-gene interactions affect IgE levels among fetus, infancy and childhood in Taiwan individuals. A birth cohort of 571 children with completion of IgE measurements from newborn to 1.5, 3, and 6 years of age was subject to genetic association analysis on the 384-customized SNPs of 159 allergy candidate genes. Fifty-three SNPs in 37 genes on innate and adaptive immunity, and stress and response were associated with IgE production. Polymorphisms of the IL13, and the HLA-DPA1 and HLA-DQA1 were, respectively, the most significantly associated with the IgE production at newborn and 6 years of age. Analyses of gene-gene interactions indentified that the combination of NPSR1, rs324981 TT with FGF1, rs2282797 CC had the highest risk (85.7%) of IgE elevation at 1.5 years of age (P = 1.46×10-4). The combination of IL13, CYFIP2 and PDE2A was significantly associated with IgE elevation at 3 years of age (P = 5.98×10-7), and the combination of CLEC2D, COLEC11 and CCL2 was significantly associated with IgE elevation at 6 years of age (P = 6.65×10-7). Our study showed that the genetic association profiles of the IgE production among fetus, infancy and childhood are different. Genetic markers for early prediction and prevention of allergic sensitization may rely on age-based genetic association profiles. © 2013 Chang et al. Source

Background. Kawasaki disease (KD) is characterized by systemic vasculitis of unknown etiology. Our previous studies showed expression of CD40 ligand on CD4+ T cells correlated to the coronary artery lesion (CAL) and disease progress in KD. Other studies from Japan suggested the role of CD40L in the pathogenesis of CAL, and this might help explain the excessive number of males affected with KD but cannot be reproduced by Taiwanese population. This study was conducted to investigate the CD40 polymorphism in KD and CAL formation. Methods. A total of 950 subjects (381KD patients and 569 controls) were investigated to identify 2 tagging single-nucleotide polymorphisms (tSNPs) of CD40 (rs4810485 and rs1535045) by using the TaqMan allelic discrimination assay. Results. A significant association was noted with regards to CD40 tSNPs (rs1535045) between controls and KD patients (P=0.0405, dominant model). In KD patients, polymorphisms of CD40 (rs4810485) showed significant association with CAL formation (P=0.0436, recessive model). Haplotype analysis did not yield more significant results between polymorphisms of CD40 and susceptibility/disease activity of KD. Conclusions. This study showed for the first time that polymorphisms of CD40 are associated with susceptibility to KD and CAL formation, in the Taiwanese population. Copyright © 2012 Ho-Chang Kuo et al. Source

Background: Exposure to cow's milk protein in early infancy could lead to increased rates of allergic diseases later in life. We investigated whether feeding a protein-hydrolyzed formula (HF) in the first 6 months of life decreased allergic diseases up to 36 months later. Methods: Newborns who had at least 1 first-degree family member with a history of atopy and could not breast-feed were enrolled. They were fed with HF or cow's milk infant formula (CM) for at least 6 months via an open-label protocol and were monitored prospectively at 6, 18 and 36 months of age to assess allergy sensitization and allergic diseases. Results: A total of 1,002 infants were enrolled and 679 infants were consistently fed the same formula for the first 6 months of life (345 HF and 334 CM). The percentage of food sensitization (especially to milk protein) was significantly lower in the HF group than in the CM group at 36 months (12.7 vs. 23.4%, p = 0.048). There was no significant difference in the prevalence of aeroallergen sensitization between the groups. Occurrence of allergic diseases during the first 3 years of life was significantly correlated with aeroallergen sensitization, but not to food allergen sensitization, parental atopy or feeding types. Conclusions: Infants fed with HF during the first 6 months of life had a significantly lower percentage of sensitization to milk protein allergens, but not allergic diseases during the first 3 years of life. Avoidance of cow's milk protein alone in infancy is not enough to decrease rates of allergic diseases. Copyright © 2010 S. Karger AG. Source
