Background. Kawasaki disease (KD) is a systemic form of self-limited vasculitis in children less than five years old, and the main complication is coronary artery injury. However, the etiology of KD remains unclear. The IL-1B polymorphisms rs16944 GG and rs1143627 AA and their diplotype GA/GA have been associated with significantly increased risk of intravenous immunoglobulin (IVIG) resistance in a Taiwanese population, but the relationship between rs16944 A/G and rs1143627 G/A and coronary artery lesions (CALs) in patients with KD has not been investigated. The present study is aimed at investigating whether the rs16944 A/G and rs1143627 G/A polymorphisms in IL-1B were associated with KD susceptibility and CALs in a southern Chinese population. Methods and Results. We recruited 719 patients with KD and 1401 healthy children. Multiplex PCR was used to assess the genotypes of single nucleotide polymorphisms (SNPs), including two SNPs of IL-1B, rs16944 A/G and rs1143627 G/A. According to the results, no significant association was observed between the IL-1B (rs16944 and rs1143627) polymorphisms and KD risk in the patients compared with the healthy controls in our southern Chinese population. However, in further stratified analysis, we found that children younger than 12 months with the rs16944 GG and rs1143627 AA genotypes of IL-1B had a higher risk of CALs than those with the AA/AG genotypes of rs16944 and GG/AG genotypes of rs1143627 (OR=2.28, 95% CI=1.32-3.95, P=0.0032, adjusted OR=2.33, 95% CI=1.34-4.04, P=0.0027). Conclusions. Our results indicated that there was no association between the rs16944 A/G and rs1143627 G/A gene polymorphisms and KD susceptibility. However, the rs16944 GG and rs1143627 AA genotypes of IL-1B may significantly impact the risk of CAL formation in children younger than 12 months, which may contribute to the pathogenesis of KD. These findings need further validation in multicenter studies with larger sample sizes.

Abstract Background: Kawasaki disease is a type of acute febrile rash disease that is common in children and is characterised by primary lesions of systemic middle and small vasculitis, which can lead to coronary artery lesions. Manganese superoxide dismutase (MnSOD), one of the most important antioxidases in the human body, plays a key role in maintaining the balance of free radicals in the human body. Two single-nucleotide polymorphisms (SNPS) (rs4880 and rs5746136) in the MnSOD gene were related to oxidative stress disease. The purpose of this study is to explore the possible relationship between MnSOD gene polymorphisms and Kawasaki disease susceptibility. Methods: This study included 100 Kawasaki disease children and 102 healthy children. Two single-nucleotide polymorphisms (rs4880 and rs5746136) were detected by polymerase chain reaction sequence-based typing. Results: There was a significant difference in both the genotype frequency (χ2 = 10.805, p = 0.005) and the allele frequency (χ2 = 7.948, p = 0.005) of rs5746136 between the Kawasaki disease group and the control group. Children with the A allele had a 0.558 times lower risk of Kawasaki disease than those without the A allele (χ2 = 7.948, p = 0.005, odds ratio = 0.558, 95% confidence interval = 0.371–0.838). There was no significant difference in the genotype and gene frequencies of rs5746136 between the Kawasaki disease-coronary artery lesion and Kawasaki disease-without coronary artery lesion groups (p > 0.05), and there was no significant difference in the rs4880 genotype and allele frequencies between the Kawasaki disease and healthy control groups or between the Kawasaki disease-coronary artery lesion and Kawasaki disease-without coronary artery lesions groups (p > 0.05). Conclusion: This study provides evidence supporting an association between MnSOD gene polymorphisms and susceptibility to Kawasaki disease. The genotype AA and the allele A of the MnSOD gene locus rs5746136 were risk factors for Kawasaki disease.

Kawasaki disease (KD) is an acute systemic vasculitis complicated by development of coronary artery lesions. PECAM-1 is a kind of cell adhesion molecule, which plays an important role in coronary artery disease. The relationship between PECAM-1 gene polymorphisms and their susceptibility to Kawasaki diseases (KD) is still unclear. In our study, we examined the PECAM-1 gene polymorphisms in 44 KD patients and 59 healthy children and revealed the correlation of PECAM-1 gene polymorphisms in KD children with and without coronary artery lesions (CAL).

A previous family-based linkage study revealed that Kawasaki disease (KD) was associated with variations of the ATP-binding cassette subfamily C member 4 (ABCC4) gene in most European populations. However, significant differences exist among ethnic populations in European and Chinese subjects; therefore, whether ABCC4 variants indicate susceptibility to KD in Chinese children is unclear. The purpose of this research was to evaluate correlations between ABCC4 gene polymorphisms and susceptibility to KD in a Southern Chinese population. We genotyped six polymorphisms (rs7986087, rs868853, rs3765534, rs1751034, rs3742106, and rs9561778) in 775 KD patients and 774 healthy controls. Ninety-five percent confidence intervals (95% CIs) and odds ratios (ORs) were used to assess the strength of each association. We found that the rs7986087 T variant genotype was associated with significantly higher susceptibility to KD (adjusted OR = 1.30, 95% CI = 1.05–1.60 for rs7986087 CT/TT). However, the rs868853 T variant genotype was associated with significantly lower susceptibility to KD (adjusted OR = 0.74, 95% CI = 0.59–0.92 for rs868853 CT/CC). Compared with the patients with 0–4 ABCC4 risk genotypes, the patients with 5-6 ABCC4 risk genotypes had a significantly increased risk of KD (adjusted OR = 1.63, 95% CI = 1.07–2.47), and this risk was more significant in the subgroups of females, subjects aged 12–60 months, and individuals with coronary artery lesions. These results indicate that specific single-nucleotide polymorphisms in the ABCC4 gene may increase susceptibility to KD in a Southern Chinese population.

Abstract Objectives Kawasaki disease (KD) is an acute systemic vasculitis of unknown aetiology that affects infants and young children. Recent reports of elevated serum high mobility group box 1 (HMGB1) level during the acute phase of KD and its relationship to poor response to IVIG treatment suggest a possible association of HMGB1 polymorphisms with KD. We investigated the association between the polymorphisms of the HMGB1 gene, KD susceptibility, coronary artery lesions, and KD response to IVIG treatment. Methods Whole genome sequencing of the HMGB1 gene was performed to identify causative variants. Two tagging single nucleotide polymorphisms of the HMGB1 gene were selected using linkage disequilibrium analysis. The tagging single nucleotide polymorphisms were genotyped using the TaqMan Allelic Discrimination assay in a total of 468 subjects (265 KD patients and 203 controls). Results The HMGB1 single nucleotide polymorphisms were not associated with KD susceptibility. However, in KD patients, there was a significant association of rs1412125 with coronary artery lesions formation in the recessive model (GG vs AA + GA: odds ratio = 4.98, 95% CI = 1.69–14.66, P = 0.005). In addition, rs1412125 was associated with IVIG resistance in the recessive (GG vs AA + GA: odds ratio = 4.11, 95% CI = 1.38–12.23, P = 0.017) and allelic models (G vs A: odds ratio = 1.80, 95% CI = 1.06–3.06, P = 0.027). Conclusion The rs1412125 in HMGB1 might be a risk factor for the development of coronary artery lesions and IVIG resistance in KD patients.

Single nucleotide polymorphisms (SNPs) in microRNA may affect its expression and regulation of target genes, which may consequently alter individual susceptibility to cancer. In this study we aimed to investigate associations betweenmiR-122polymorphisms and hepatocellular carcinoma (HCC) in a southern Chinese population. Three selected SNPs inmiR-122(rs9966765, rs1135519, and rs17669) were genotyped in 1050 HCC patients and 1079 cancer-free controls using Sequenom MassARRAY platform and the associations of the three SNPs and HCC risk were evaluated. We found that individuals with the rs1135519 CC genotypes had a significant increased risk of HCC than those with TT genotypes (adjusted OR=2.71, 95% CI=1.15-6.36, andP=0.022), while the rs9966765 CC genotypes showed a borderline significant association with increased risk of HCC when compared with the GG genotypes (adjusted OR=2.38, 95% CI=0.99-5.75, andP=0.052). There was also a significant increased risk of HCC when combining risk genotypes of these loci, i.e., rs1135519 CC and rs9966765 CC. Compared with the low-risk group (0 risk genotype), the high risk group (1-2 risk genotypes) had significantly increased risk of HCC (OR=1.61, 95% CI=1.05-2.44, andP=0.028). Further genotype-expression analysis revealed that cases carrying the CC genotype of rs1135519 had lower levels ofmiR-122expression than those with the TT genotype. Our results suggest that SNP of rs1135519 modulatesmiR-122expression and contributes to the genetic susceptibility of HCC, either independently or together with rs9966765 inmiR-122.Further well-designed studies with lager sample sizes are needed to confirm our findings.

Background: Kawasaki disease (KD) is an inflammatory disease associated with coronary vasculitis in children. In this study, we explored the correlation between Lipoprotein associated phospholipase A2 (Lp-PLA2) and coronary artery lesions (CAL) in children with KD. Methods: Ninety-three children with KD were divided into a normal coronary artery (NCA, 54 cases) group and coronary artery lesions (CAL, 39 cases) group, according to the results of echocardiography. Another 42 healthy children were selected as the control group. The serumal levels of Lp-PLA2, Interferon-γ(IFN-γ) and Interleukin-6 (IL-6) were determined by using an enzyme-linked immunosorbent assay. In addition, erythrocyte sedimentation rate (ESR) and serum C-reactive protein (CRP) level were analyzed. The left main coronary artery (LMCA), diameters of left anterior descending coronary artery (LADC), right proximal coronary artery (PRCA), and carotid intima-media thickness (IMT) were obtained by color Doppler ultrasound. The correlation between the above indexes and KD was analyzed. Results: The levels of white blood cell counts (WBC), ESR, CRP, IFN-γ, IL-6 and Lp-PLA2 as well as IMT were significantly increased in KD children (P < 0.05), and the levels of CRP, IFN-γ, IL-6 and Lp-PLA2 as well as IMT in the CAL group increased more significantly (P < 0.05). An increasing trend also has been described in the diameters of LMCA, LADC and PRCA for KD children with CAL compared with with NCA. The results of logistic regression analysis showed that the elevated levels of CRP, IFN-γ, IL-6 and Lp-PLA2 were independent risk factors for KD with CAL. Correlation analysis showed that Lp-PLA2 level was positively correlated with the levels of IFN-γ, IL-6 and CRP in CAL group and NCA group (respectively, all P < 0.01). In addition, a similar correlation was also described between Lp-PLA2 level and the diameters of LMCA, LADC and PRCA in CAL group (respectively, all P < 0.01). Conclusion: Lp-PLA2 may participate in the pathological mechanism of KD. Detection of the serum Lp-PLA2 level can be used in the diagnosis of KD disease and the assessment of coronary artery lesions in KD children.

miR-146a plays a critical role in innate immune and inflammatory responses. Kawasaki disease involves immune-mediated inflammatory responses, which leads to vascular endothelial injury. However, there has been no study on the association between the miR-146a rs2910164 C>G polymorphism and Kawasaki disease risk. We enrolled 532 Kawasaki disease patients and 623 healthy controls from southern Chinese population, and the miR-146a rs2910164 C>G polymorphism was genotyped by the TaqMan method. There was no evidence that this polymorphism was associated with Kawasaki disease. Stratified analysis also showed no significant association. The present study indicates that the miR-146a rs2910164 C>G polymorphism may not be associated with Kawasaki disease in the southern Chinese population. Larger multicenter studies are needed to confirm our conclusions.
