A nomogram for predicting coronary artery lesions in patients with Kawasaki disease.

As an acute systemic vasculitis, Kawasaki disease (KD) could develop coronary artery lesions (CAL) sometimes. However, its etiology was still unidentified. This study was to construct a predictive model based on clinical features and laboratory parameters, and then perform a rapid risk assessment of CAL. We collected clinical and laboratory data retrospectively for all patients with KD who were hospitalized at our hospital from January 2016 to June 2023. All the patients were divided into CAL and non-CAL groups and then randomly assigned to a training set and a verification set. The independent risk variables of CAL were identified by univariate analysis and multivariate logistic regression analysis of the training set. These components were then utilized to build a predictive nomogram. Calibration curve and receiver operating characteristic curve were used to evaluate the performance of the model. The predictive nomogram was further validated in the verification set. In the training set, 49 KD patients (19.9%) showed CAL. Compared with the non-CAL group, the proportion of fever days ≥ 10, C-reactive protein and total bilirubin were significantly higher in the CAL group, whereas age was younger, hemoglobin and albumin were lower. Younger age, fever days ≥ 10, higher C-reactive protein, lower hemoglobin and albumin were identified as independent risk factors for CAL in KD patients. The nomogram constructed using these factors showed satisfactory calibration degree and discriminatory power (the area under the curve, 0.764). In the verification set, the area under the curve was 0.798. Younger age, fever days ≥ 10, lower hemoglobin and albumin levels, higher C-reactive protein levels were independent risk factors for CAL in KD patients. The predictive nomogram constructed utilizing 5 relevant risk factors could be conveniently used to facilitate the individualized prediction of CAL in KD patients.

Whole-exome sequencing reveals Kawasaki disease susceptibility genes and their association with coronary artery lesion.

This study aimed to explore Kawasaki disease (KD) susceptibility genes and their complications like coronary artery lesions (CAL) using whole exome sequencing (WES). Between April 1, 2021, and December 31, 2022, our study included 55 pediatric patients diagnosed KD at our center, alongside a cohort of healthy children who sought medical care at our institution during the same timeframe. We extracted peripheral blood DNA from all participants and employed the advanced high-throughput Illumina Next-Generation Sequencing technology for comprehensive analysis. Through bioinformatics evaluation, we identified potential susceptibility genes. Moreover, from the 55 KD patients, we selected 15 for the CAL group and 40 for the non-CAL group. We aimed to investigate whether there were significant differences in the allele frequencies of the targeted susceptibility genes between these subgroups, to explore the risk alleles associated with the development of CAL in KD. HLA-DRB1 rs17882084 and IL6ST rs781455079 genotypes and alleles differed significantly between KD and non-KD (P < 0.05). No differences existed for IL17RC rs143781415 and VEGFB rs776229557 (P > 0.05). No differences in HLA-DRB1 rs17882084, IL6ST rs781455079, and VEGFB rs776229557 genotypes existed between CAL and non-CAL groups (P > 0.05). However, the IL17RC rs143781415 genotype differed significantly between them (P < 0.05). HLA-DRB1 rs17882084 and IL6ST rs781455079 genotypes may be potential KD susceptibility gene candidates. Specifically, HLA-DRB1 rs17882084 GA genotype and A allele, and IL6ST rs781455079 TC genotype and C allele may increase KD risk. Additionally, the IL17RC rs143781415 genotype may increase CAL risk in KD patients.

Analysis of ultrasound coronary parameters and blood red cell distribution width and N-terminal pro-brain natriuretic peptide concentrations following coronary lesions in children with Kawasaki disease.

Aims/Background Kawasaki disease is an acute inflammatory condition primarily affecting the young children. It can lead to coronary artery abnormalities, which can worsen the prognosis. Early diagnosis of coronary disease is crucial for the effective treatment and the prognosis evaluation. To explore the clinical significance of ultrasound examination characteristics, peripheral blood red cell distribution width, and changes in N-terminal pro-brain natriuretic peptide levels for the early detect coronary artery abnormality in children with Kawasaki disease. Methods The case-control study was conducted. 85 Kawasaki disease patients diagnosed in our hospital from January 2020 to December 2023 were selected as the Kawasaki disease group. 100 healthy children who received physical examination in the Department of Child Healthcare during the same period were selected as control group. The cardiac ultrasound indicators, erythrocyte sedimentation rate, C-reactive protein, white blood cell, neutrophil percentage, platelet count, D-dimer, red cell distribution width, N-terminal pro-brain natriuretic peptide of two groups were compared. The Kawasaki disease group was further divided into the coronary artery lesion group and the non-coronary artery lesion group based on whether coronary artery lesions occurred in the Kawasaki disease patients. The differences of above indicators were compared. Results The left main coronary artery, left anterior descending branch, and right coronary artery Z-scores of the Kawasaki disease group were all higher than those of the control group (p < 0.05). There was no significant difference in left ventricular ejection fraction between Kawasaki disease group and control group (p > 0.05). The erythrocyte sedimentation rate, C-reactive protein, neutrophil percentage, platelet count, D-dimer, red cell distribution width, and N-terminal pro-brain natriuretic peptide of Kawasaki disease group were all higher than those of control group (p < 0.05). The left main coronary artery, left anterior descending branch, and right coronary artery Z-scores of Kawasaki disease patients with coronary artery lesions were all higher than those of Kawasaki disease patients without coronary artery lesions (p < 0.05). The left ventricular ejection fraction of Kawasaki disease patients with coronary artery lesions was lower than that of Kawasaki disease patients without coronary artery lesions (p < 0.05). The erythrocyte sedimentation rate, C-reactive protein, white blood cell, neutrophil percentage, platelet count, D-dimer, red cell distribution width, and N-terminal pro-brain natriuretic peptide of Kawasaki disease patients with coronary artery lesions were all higher than those of Kawasaki disease patients without coronary artery lesions, and the differences were statistically significant (p < 0.05). After treatment, the left main coronary artery, left anterior descending branch, and right coronary artery Z-scores of Kawasaki disease patients with coronary artery lesions significantly decreased (p < 0.05), and the left ventricular ejection fraction significantly increased (p < 0.05). The erythrocyte sedimentation rate, C-reactive protein, white blood cell, neutrophil percentage, platelet count, D-dimer, red cell distribution width, and N-terminal pro-brain natriuretic peptide of Kawasaki disease patients with or without coronary artery lesions significantly decreased after treatment compared with before treatment in the same group (p < 0.05). Conclusion Kawasaki disease patients with coronary artery lesions exhibit significantly increased coronary artery vessel diameter, as well as elevated red cell distribution width and N-terminal pro-brain natriuretic peptide concentration. The combined use of ultrasound combined with red cell distribution width and N-terminal pro-brain natriuretic peptide examination can assist in determining whether Kawasaki disease patients have coronary artery lesions and assessing the clinical treatment effect.

Expression of Oxidative Stress and Inflammatory Indicators for Coronary Artery Disease in Kawasaki Disease.

The paper was to investigate the clinical relevance of oxidative stress (OS) and inflammation-associated targets in coronary artery lesions (CALs) associated with Kawasaki disease (KD). The clinical data from 455 sufferers diagnosed with KD between February 2021 and June 2023 were gathered and divided into two groups: CAL and NCAL. The regression analysis was conducted to search for independent covariates for CALs related to OS and inflammation. The predictive nomogram was structured according to these risk factors. The properties of the model were estimated using calibration and receiver operating characteristic curves. The levels of CRP, IL-6, PLT count, ESR, ox-HDL, MDA, and PLR were more elevated in CAL patients with KD; interestingly, HDL and superoxide dismutase (SOD) were low in the CAL group. Ascension of CRP, IL-6, ESR, ox-HDL, MDA, and PLR, and diminution of HDL and SOD were considered independent risk factors. The nomogram constructed using these factors demonstrated a satisfactory calibration degree and discriminatory power, with an area under the curve of 0.812. In the verification set, the area under the curve was found to be 0.799. The model was established according to 8 OS and inflammation-associated risk factors bound up with CALs in KD sufferers. It may be a usable approach for early diagnosis of CALs in KD.

Explorative case control study on the associations of serum vitamin D3, folic acid and vitamin B12 levels on Kawasaki disease and coronary artery lesions.

Kawasaki Disease (KD) is a pediatric vasculitic disorder characterized by systemic small vasculitis, notably coronary arteritis, with unclear pathogenesis. This explorative case-control study investigated the association between folic acid (FA), vitamin D3 (VD3), and vitamin B12 (VB12) levels and the different types of Kawasaki Disease, as well as the incidence of coronary artery lesions (CALs). In this explorative case control study, 365 KD children admitted to our hospital from January 1, 2022 to June 30, 2023 were included as the KD group. Simultaneously, 365 healthy children who received physical examination during the same period were included as the control group. The KD group was divided into typical KD group and incomplete KD group (IKD group), CALs group and non-CALS group, and IVIG sensitive group and IVIG resistant group. The children with CALs were divided into small tumor group, medium tumor group and large tumor group. Serum levels of FA, VB12, and VD3 were compared across all groups. Serum levels of FA and VD3 were significantly decreased in both the KD and CALs groups (p < 0.05), and both factors were identified as independent risk factors for KD and CALs. Similarly, reduced serum VD3 levels were observed in the IKD and IVIG-resistant groups (p < 0.05), with VD3 also being an independent risk factor for both IKD and IVIG resistance. Additionally, lower serum FA levels were noted in the group with large aneurysms (p < 0.05), establishing FA as an independent risk factor for aneurysm size. Serum levels of folic FA and vitamin VD3 were significantly reduced in children with KD. Furthermore, these reductions were more pronounced in children with IKD and CALs. This pattern suggests that lower FA and VD3 levels may increase the risk of more severe coronary lesions in KD patients. Therefore, monitoring these biomarkers could provide valuable insights for early clinical diagnosis and intervention.

The role of serum lipid in predicting coronary artery lesions and intravenous immunoglobulin resistance in Kawasaki disease: a cohort study.

To assess the predictive value of the serum lipid profile for initial intravenous immunoglobulin (IVIG) resistance and coronary artery lesions (CALs) in patients with Kawasaki disease (KD). This retrospective cohort study enrolled patients with KD and divided them into IVIG-responsive and IVIG-resistant groups. They were also stratified based on the presence of CALs (CALs and non-CALs groups). Clinical, echocardiographic and biochemical values were evaluated. A subgroup analysis was performed on complete and incomplete KD. Predictors of initial IVIG resistance and CALs were determined by multivariate logistic regression analysis. A total of 649 KD patients were enrolled: 151 had CALs and 76 had initial IVIG resistance. Low-density lipoprotein cholesterol (LDL-C) was significantly lower in the IVIG-resistant group than in the IVIG-responsive group. LDL-C and apolipoprotein (Apo) B were significantly lower in the CALs group compared with the non-CALs group. Multivariate logistic regression failed to identify the serum lipid profile (LDL-C, Apo A or Apo B) as an independent risk factor for initial IVIG resistance or CALs in KD patients. KD patients might have dyslipidaemia in the acute phase, but the serum lipid profile might not be suitable as a single predictor for initial IVIG resistance or CALs.

MRI Diagnosis of Coronary Artery Lesions in Children With Kawasaki Disease and Their Correlation With Inflammatory Factors.

Ultrasonography (US), as a routine examination for evaluating coronary artery lesions (CAL) in children with Kawasaki disease (KD), has strong subjectivity and limitations. Non-contrast enhanced coronary magnetic resonance angiography (NCE-CMRA) is sensitive and reliable in displaying the segments of coronary arteries (CA). To evaluate the CA using NCE-CMRA, to compare NCE-CMRA with US, and to assess the correlation between KD-related inflammatory factors and the occurrence of CAL. Retrospective. 61 children with KD who had undergone NCE-CMRA. Ultimately, 52 cases were included (32 males and 20 females), with an average of 5.9 ± 0.3 years old. 3-T, 3D balanced turbo field echo sequence. NCE-CMRA and US coronary visualization rates were compared in 41 children who were imaged with both techniques. Inflammatory factors were compared between CAL and normal coronary artery (NCA) subgroups. In the CAL group, correlations of these inflammatory factors with CAL parameters were investigated. Comparison between groups was performed by the two independent samples t-test; the comparison of enumeration data between groups was performed by chi-square test. Receiver operating characteristic (ROC) curve analysis was performed to determine the sensitivity of inflammatory factors for detecting CAL. The correlation between CAL and inflammatory indexes was analyzed by multiple linear regression. A P value <0.05 was considered statistically significant. NCE-CMRA visualized significantly more segments than US (76% vs. 46%). There were significant differences in PLT, CRP, ESR, and D-dimer between the CAL and NCA groups. ROC curve analysis showed that the sensitivities of these four indicators in diagnosing CAL were 39%, 44%, 72%, and 61%, respectively, at cut-off points of 562.5 × 109 /L, 48.93 mg/L, 45.5 mm/h, and 0.5 mg/L, respectively. The combination of NCE-CMRA and inflammatory factors is helpful for the early diagnosis and disease severity of CAL in children with KD. 3 TECHNICAL EFFICACY: Stage 2.

Relationship between serum plasminogen activator and D-dimer levels and the severity of Kawasaki disease in children as well as their predictive value for coronary artery lesion.

To evaluate the relationships between serum plasminogen activator (PA) and D-dimer levels, the severity of Kawasaki disease (KD) in children, and their ability to predict coronary artery lesions (CAL). This retrospective study analyzed the clinical data of 102 children diagnosed with KD at the Affiliated Hospital of Jiangnan University from January 2020 to September 2023. The cohort was divided into two groups: 31 children with CAL in the CAL group and 71 without it in the non-CAL group. The study assessed the incidence of CAL and investigated the correlations between serum PA and D-dimer levels and various inflammatory markers (white blood cell (WBC) count, platelet count, and erythrocyte sedimentation rate (ESR)). Receiver operating characteristic (ROC) curves were used to evaluate the predictive value of these biomarkers for CAL. CAL was present in 30.04% of the children. Pearson correlation analysis revealed that serum PA levels were inversely correlated with WBC count (P = 0.0187), platelet count (P = 0.0116), and ESR (P = 0.0041), while D-dimer levels were positively correlated with these markers (P < 0.001). A negative correlation between PA and D-dimer levels was also observed (P < 0.001). The combined use of PA and D-dimer levels to predict CAL achieved an area under the curve of 0.871. Serum PA levels were negatively associated with the severity of KD, whereas D-dimer levels were positively associated. Together, these markers showed significant predictive value for CAL, highlighting their utility in assessing disease severity and guiding management in children with KD.

Early Clinical Evaluation of Coronary Artery Lesions in Kawasaki Disease.

The purpose of this study is to analyze the early clinical features of coronary artery lesion (CAL) in Kawasaki disease (KD), evaluate systemic inflammation indicators, and enhance early recognition of CAL in the acute phase of KD. A total of 314 children with KD were divided into those with CAL (CAL group) and without CAL (NCAL group) using echocardiographic results, and their clinical data were retrospectively analyzed. For KD patients, male, children aged 3 to 9 years, and those with fever longer than 6 days before intravenous immunoglobulin (IVIG) use were more likely to have CAL. There were significant differences in sex, age, and fever time (P < .05). Moreover, some laboratory indicator test results revealed there was a significant difference between N-terminal pro-brain natriuretic peptide (NT-pro-BNP) and interleukin-6 (IL-6), and the CAL (P < .05). This study has certain guiding significance for early clinical evaluation.

Clinical indicators combined with S100A12/TLR2 signaling molecules to establish a new scoring model for coronary artery lesions in Kawasaki disease.

Coronary artery lesions (CALs) are the most common and serious complication of Kawasaki disease (KD), and the pathogenesis is unknown. Exploring KD-specific biomarkers and related risk factors is significant for clinical diagnosis and treatment. This study aimed to explore the feasibility of combining clinical indicators with S100A12/TLR2-associated signaling molecules for the predictive modeling of CALs in KD. A total of 346 patients (224 males and 122 females) with KD who visited the rheumatology department of Wuhan Children's Hospital between April 2022 and March 2025 were enrolled and divided into two groups according to the presence or absence of CALS (292 patients had CALs and 54 patients did not). Forty-one variables were collected from the two groups, including demographic characteristics, clinical manifestations, and laboratory data. Single nucleated cells from each patient were extracted, and the expression of the S100A12/TLR2 signal transduction-related molecules S100A12, TLR2, MYD88, and NF-κB were detected by real-time fluorescent quantitative polymerase chain reaction. Statistically significant variables were subjected to logistic regression analysis to determine the independent risk factors for KD with CALs, and a new risk score model was established to assess the predictive efficacy based on receiver operating characteristic curves. Sixteen variables significantly differed between the no-CALs and CALs groups: gender, fever duration, white blood cells (WBC), hemoglobin (HGB), Ce reactive protein (CRP), procalcitonin, serum ferritin (SF), erythrocyte sedimentation rate (ESR), fibrinogen (FIB), aspartate aminotransferase-to-alanine aminotransferase ratio (AST/ALT), serum albumin (ALB), sodium (Na), Interleukin (IL-10), tumor necrosis factor (TNF-α), S100 calcium binding protein A12 (S100A12), and Myeloid Differentiation Factor 88 (MYD88) (p < 0.05). After performing a univariate analysis, 12 variables (gender, fever duration, WBC, HGB, CRP, SF, ESR, FIB, AST/ALT, ALB, Na, and S100A12) were included in the multifactorial binary logistic regression, which showed that fever duration ≥ 6.5 days, ESR ≥ 46.5 mm/h, AST/ALT ≤ 1.51, and S100A12 ≥ 10.02 were independent risk factors for KD with CALs and were assigned scores of 3, 2, 1, and 2, respectively, according to the odds ratio (OR). The total score of each patient was counted, and a new prediction model for KD combined with CALs was established, where < 3.5 was considered low risk and ≥ 3.5 was regarded as high risk; the sensitivity, specificity, Jorden index, and area under the curve of this scoring system were 0.667, 0.836, 0.502, and 0.838, respectively. This new scoring model has good efficacy for predicting the occurrence of KD with CALs. The expression of S100A12 was significantly increased in the CALs group and was an independent risk factor for the occurrence of CALs, and has the potential as a biomarker for predicting KD with CALs.

Clinical value of echocardiography combined with serum Cav-1, NFATc1, and PAI-1 in the diagnosis of Kawasaki disease complicated with coronary artery lesions.

To analyze the clinical value of echocardiography combined with serum lacuna protein-1 (Cav-1), activated T cell nuclear factor C1 (NFATc1), and plasminogen activator inhibitor-1 (PAI-1) in the diagnosis of Kawasaki disease (KD) complicated with coronary artery lesions (CAL). A total of 200 children with KD treated in our hospital from January 2019 to October 2021 were grouped as the KD alone group (n = 56) and the KD complicated with CAL group (n = 144) according to the results of coronary angiography. The levels of Cav-1, NFATc1, and PAI-1 were detected by enzyme-linked immunosorbent assay. Echocardiography was performed and the internal diameters of left and right coronary arteries were compared between the two groups. The area under the curve (AUC), sensitivity, and specificity of echocardiography combined with serum Cav-1, NFATc1, and PAI-1 in the diagnosis of KD complicated with CAL were analyzed with receiver operating characteristic (ROC) curve. Coronary angiography, as the gold standard, showed that the sensitivity of echocardiography in diagnosing KD with CAL was 88.19% (127/144), the specificity was 66.07% (37/56), and the accuracy was 82.00% (164/200). ROC curve analysis revealed that the AUC of KD complicated with CAL diagnosed by echocardiography, Cav-1, NFATc1, and PAI-1 was 0.819, 0.715, 0.688, and 0.663, respectively, and the AUC of combined diagnosis of the four was 0.896. The combination of echocardiography, Cav-1, NFATc1, and PAI-1 has high value in diagnosing KD complicated with CAL, which can be widely used in clinical practice.

Clinical manifestations and risk factors of coronary artery lesions in children with Kawasaki disease.

To analyze the clinical manifestations of children with Kawasaki disease (KD), and risk factors of coronary artery lesion (CAL). A total of 223 patients admitted to Anhui Children Hospital from January 2017 to December 2019 were enrolled. According to the clinical data, the children with KD were divided into complete Kawasaki disease (CKD) and incomplete Kawasaki disease (IKD) groups. According to the results of the cardiac color ultrasound, the children were divided into the CAL and nCAL groups. The clinical symptoms of children with KD were compared between the CKD and IKD groups. The risk factors of CAL were analyzed by univariate and binary logistic regression analyses. The incidence constituent ratio of KD increased annually from 2017 to 2019 (P < .05). The proportion of fever duration no longer than 10 days, chapped lips, fingertip decrustation, perianal desquamation, and fever combined with rash in the CKD group was significantly higher compared to the IKD group (P < .05), while intravenous immunoglobulin non-response and CAL were significantly lower than those in the IKD group (P < .05). The proportion of males, age <1 year, fever duration longer than 10 days, and IKD in the CAL group were significantly higher compared to the nCAL group, while hemoglobin levels were significantly lower than that in the nCAL group (P < .05). Sex, age, fever duration, atypical KD, and hemoglobin levels were risk factors for CAL in children with KD. Persistent fever, conjunctival hyperemia, chapped lips, and rash were common clinical symptoms in children with KD. The risk of CAL was relatively higher in children with low hemoglobin levels and IKD, whose ages were <1 year old and whose fever time was more than 10 days, which requires high clinical vigilance.

Relationship between IL-17A gene polymorphism and susceptibility to Kawasaki disease.

Kawasaki disease (KD) is the most common autoimmune vasculitis syndrome in children, which supposed be a complex polygenic disorder. Interleukin-17 (IL-17) is a member of the pro-inflammatory cytokine family, which has a strong pro-inflammatory effect and can participate in various acute and chronic inflammatory responses. This study aims to investigate the relationship between the single-nucleotide polymorphism (SNP) locus rs3819025 in the IL-17A gene and the susceptibility to KD. A total of 120 patients with KD who met the diagnostic criteria (the KD group) and 120 healthy children (the control group) were enrolled retrospectively in this study. Polymerase chain reaction (PCR) and DNA direct sequencing were used to detect the SNPs of children in the 2 groups. The frequencies of GG, GA, and AA genotypes of rs3819025 locus in the IL-17A gene in the KD group were 82.5%, 17.5%, and 0, respectively, and the frequencies of GG, GA, and AA genotypes in the control group were 72.5%, 22.5%, and 5.0%, respectively. There were significant differences in both genotype (χ2=7.524, P=0.023). The allele frequencies G and A of rs3819025 locus in the KD group were 91.25% and 8.75%, respectively, while those in the control group were 83.75% and 16.25%, respectively. There was significant difference between the 2 groups (χ2=6.171, P=0.013). The distribution frequencies of GG or GA genotype and G or A allele were 88.46% or 11.54% and 94.23% or 5.77% in the KD group with coronary artery lesion, respectively. The distribution frequencies of GG or GA genotype and G or A allele were 78.72% or 21.28% and 89.36% or 10.64% in the KD group without coronary artery lesion, respectively. There were no significant differences in genotype and allele frequencies of rs3819025 between the KD with coronary artery lesion group and the KD group without coronary artery lesion (both P>0.05). Besides, children with the allele A had a 2.023 times higher risk of KD than those without the allele A (χ2=6.171, P=0.013; OR=2.023, 95% CI 1.151 to 3.557). The locus rs3819025 in the IL-17A gene is associated with the pathogenesis of KD. The allele A of the locus rs3819025 in the IL-17A gene may be a risk factor for KD.

Diagnostic performances of D-dimer, prothrombin time, and red blood cell distribution width for coronary artery lesion in children with acute stage Kawasaki disease.

To evaluate the performances of D-dimer, prothrombin time (PT), and red blood cell distribution width (RDW) for the diagnosis of coronary artery lesion (CAL) in acute stage Kawasaki disease (KD). Between January 2018 and January 2021, a total of 102 children with acute stage KD were included in this retrospective study. Among them, 36 KD children with CAL were divided into the CAL group, and 66 KD children without CAL were divided into the NCAL group. Independent predictors of CAL in acute stage KD were identified by using univariate and multivariate logistic regression analysis. Spearman correlations were used to evaluate the association between CAL in acute stage KD and different indicators. The diagnostic performance of different indicators for CAL in acute stage KD was analyzed by the receiver operating characteristic (ROC) curve. Compared with the NCAL group, children in the CAL group had significantly higher white blood cell count, lymphocyte count, platelet count, D-dimer, and RDW levels, but lower PT levels (all p < 0.05). Logistic regression analysis revealed that D-dimer (OR = 1.0, 95% CI: 1.004-1.012, p < 0.001), PT (OR = 0.4, 95% CI: 0.2-0.8, p = 0.01), and RDW (OR = 7.0, 95% CI: 2.6-19.2, p < 0.001) were independent predictors of CAL in children with acute stage KD. CAL showed a positive correlation with D-dimer (r = 0.4, p < 0.001) and RDW (r = 0.5, p < 0.001), and had a negative association with PT (r = -0.2, p < 0.05). The ROC curve analysis showed that the combination of the three indicators had the highest diagnostic performance for CAL in acute stage KD with an area under the curve (AUC) of 0.922 (sensitivity, 86.1%; specificity, 89.4%), compared with D-dimer (AUC = 0.736), PT (AUC = 0.640), and RDW (AUC = 0.819) alone. A combination of D-dimer, PT, and RDW may help predict CAL in children with acute stage KD.

Clinical characteristics and risk factors of coronary artery lesions in chinese pediatric Takayasu arteritis patients: a retrospective study

BackgroudTo summarize the clinical characteristics and identify the risk factors for pediatric Takayasu arteritis (TAK) with coronary artery lesions (CALs).MethodsClinical data of pediatric TAK patients in our center were retrospectively assessed. Independent risk factors for CALs were identified using multivariate logistic regression analysis. Survival analysis was used to compare differences in survival rates between the groups.ResultsAmong the 66 pediatric TAK cases, the incidence of accompanying CALs was 39.4%. In the CAL group, 19 (73.1%) cases started within 36 months. None of the patients had symptoms of angina or ischemia on electrocardiogram (ECG), the CALs were detected using coronary ultrasound. The CALs most commonly were the left main and right coronary arteries. The lesions were mostly small or middle coronary artery aneurysms; some children may have giant coronary aneurysmal dilations, thrombosis and heart failure. The age of onset and symptom onset to diagnosis in TAK patients with CAL were lower than those in TAK patients without CAL(P < 0.005). TAK patients with CAL had significantly higher CRP,WBC, PLT,TNF-α and IL-2R levels (P < 0.05), lower HGB (P = 0.01), lower rate of renal artery stenosis (RAS) (P = 0.009). In multivariate logistic regression, the risk factors for pediatric TAK combined with CAL included the age of TAK onset (OR = 0.9835, 95% CI: 0.9710–0.9946, P = 0.006) and RAS (OR = 0.1901, 95% CI: 0.0386–0.7503, P = 0.03). In addition, there was no significant difference in survival rates between the two groups after regular treatment.ConclusionThis study showed that the occurrence of CAL in pediatric TAK patients has a relatively more rapid clinical course, and a stronger inflammatory state at the time of diagnosis. The earlier the age of TAK onset and without RAS are more likely to cause CAL.

Prediction of coronary artery lesions based on C-reactive protein levels in children with Kawasaki Disease: a retrospective cohort study

ObjectiveSince coronary artery lesions (CALs) are the most severe complication of Kawasaki disease (KD), clinically speaking, early prediction of CALs is crucial. The authors aimed to investigate the predictive value of C-reactive protein (CRP) in predicting CALs in KD patients. MethodsKD patients were divided into the CALs group and the non-CALs group. The clinical and laboratory parameters were collected and compared. Multivariate logistic regression analysis was used to determine the independent risk factors of CALs. The receiver operating characteristic curve was applied to determine the optimal cut-off value. Results851 KD patients who met the inclusion criteria were studied, including 206 in the CALs group and 645 in the non-CALs group. Children in the CALs group had significantly higher CRP levels than the non-CALs group (p < 0.05). Multivariable logistic regression analysis showed that incomplete KD, male, lower hemoglobin, and higher CRP were independent risk factors for predicting CAL (all p < 0.05). The optimal cut-off value of initial serum CRP for predicting CALs was 105.5 mg/L, with a sensitivity of 47.57% and a specificity of 69.61%. In addition, KD patients with high CRP (≥105.5 mg/L) had a higher occurrence of CALs than those with low CRP (<105.5 mg/L) (33% vs 19%, p < 0.001). ConclusionThe incidence of CALs was significantly higher in patients with high CRP. CRP is an independent risk factor for CALs formation and may be useful for predicting CALs in KD patients.

The role of red blood cell distribution width in predicting coronary artery lesions in pediatric patients with kawasaki disease.

Recent studies have shown that red blood cell distribution width (RDW) has emerged as a novel predictor of cardiovascular diseases. We aim to investigate the association between RDW and the risk of coronary artery lesions (CALs) in pediatric patients with Kawasaki disease (KD). KD patients were classified as the CALs group (patients with CALs) and non-CALs group (patients without CALs). Differences among the groups were analyzed by Mann-Whitney U-test and Chi-square analysis. The independent risk factors of CALs were identified by multivariate logistic regression analysis, followed by receiver operating characteristic (ROC) curve analysis to calculate the optimal cut-off value. The red blood cell distribution width (RDW) and C-reactive protein were significantly higher in the CALs group than those in the non-CALs group (p < 0.01). Multivariate logistic regression analysis revealed that RDW (OR = 5.2, 95% CI, 4.064 to 6.654) was independent risk factors of CALs in KD patients (p < 0.01). The subgroup analysis also confirmed that the high level of RDW was an independent risk factor for the development of CALs in patients with complete and incomplete KD. The ROC analysis showed the optimal cut-off value of RDW for predicting CALs was >13.86%, with a sensitivity of 75.79% and specificity of 92.81% (AUC = 0.869, 95% CI = 0.844-0.892; p < 0.0001). RDW is an independent predictor with high sensitivity and specificity to predict CALs in KD patients. The elevation in RDW level (>13.86%) may be used as novel biomarkers for early predicting CALs in KD patients during the acute phase.

Indicators of Oxidative Stress in the Prediction of Coronary Artery Lesions in Patients With Kawasaki Disease.

The aim of this study was to examine the clinical significance of oxidative stress (OS)-related indices, including inflammatory markers and lipid and platelet (PLT) parameter, in coronary artery lesions (CALs) in Kawasaki disease (KD). Clinical data of 952 KD patients diagnosed between January 2019 and March 2022 were collected and divided into CAL and NCAL groups. All the KD patients were randomly divided into training set and verification set. The univariate analysis and multivariate logistic regression analysis of training set were used to identify the OS-related independent risk factors of CALs, which were then used to construct a predictive nomogram. Calibration curve and receiver operating characteristic curve were used to evaluate the performance of the model. The predictive nomogram was further validated on verification set. In the training set, 137 KD patients (18.0%) showed CALs. C-reactive protein, serum amyloid A, PLT count, monocyte-to-high-density lipoprotein (HDL) ratio, and PLT-to-lymphocyte ratio were significantly higher, whereas HDL was lower in the CAL group than the NCAL group. Increased C-reactive protein, serum amyloid A, PLT, and decreased HDL were identified as independent risk factors. The nomogram constructed using these factors showed satisfactory calibration degree and discriminatory power (the area under the curve, 0.887). In the verification set, the area under the curve was 0.795. The predictive nomogram constructed using 4 OS-related risk factors associated with CALs in patients with KD could be a useful tool for early diagnosis of CALs in KD.

The Predictive Values of MMP-9, PLTs, ESR, and CRP Levels in Kawasaki Disease with Cardiovascular Injury.

Objective To explore the levels of matrix metalloproteinase-9 (MMP-9), platelets (PLTs), C reactive protein (CRP), and erythrocyte sedimentation rate (ESR) and their predictive values in Kawasaki disease (KD) with cardiovascular injury. Methods 128 children were diagnosed with KD in the Lanzhou University Second Hospital. 75 patients had coronary artery lesion (CAL), while 53 patients did not. The levels of MMP-9, PLTs, and CRP and ESR in the two groups were determined. The area under the curve (AUC) of the receiver-operating characteristic (ROC) curve and the Youden index (YI) were used to evaluate the efficacy of MMP-9, PLTs, ESR, and CRP for predicting CALs in KD. Results The mean age of the patients was 2.7 ± 2.03 years (range, 2 months to 11 years). There were 87 boys (67.97%) and 41 girls (32.03%). In contrast to the NCAL group, the CAL group had obviously higher levels of MMP-9, PLTs, and CRP and an obviously higher ESR (P < 0.05). MMP-9 showed a linear positive correlation with ESR (P < 0.05) and CRP (P < 0.05). The AUC of the combined detection of the four indicators was 0.877, the sensitivity was 85.07% and the specificity was 78.95%. Conclusion MMP-9, PLTs, ESR, and CRP are important indicators for a CAL in KD. The efficacy of the combined detection of MMP-9, PLTs, ESR and CRP is better than that of any single indicator for predicting a CAL in KD.

Analysis of Risk Factors for Coronary Artery Lesion in Children with Kawasaki Disease.

To determine the frequency of coronary artery lesion (CAL) in children with Kawasaki disease (KD) and to analyse the related risk factors of CAL and the predictive value of risk factors for CAL. A descriptive study. Department of Pediatrics, People's Hospital of Linquan County, Anhui Province, China, from January 2019 to January 2022. Clinical data of 71 children with KD were retrospectively analysed, including 31 in the CAL group and 40 in the non-CAL group. The age, gender, days of fever, blood routine, plasma N-terminal B-type natriuretic peptide (NT-proBNP), and Kobayashi score were registered as independent variables of all the children, and the presence or absence of CAL was used as the dependent variable. All the independent variables were subjected to univariate analysis between the groups, and those with significance in univariate analysis were further subjected to unconditional binary logistic regression analysis. A receiver operating curve (ROC) was drawn to analyse the predictive power and optimal cut-off value of related risk factors for CAL. On univariate analysis, age, NT-proBNP and Kobayashi's score were closely related to CAL (all p<0.05). Multivariate analysis showed that NT-proBNP and Kobayashi scores were independent risk factors for CAL in children with KD. ROC curve analysis showed that the area under the curve (AUC) of NT-proBNP and Kobayashi scores were 0.771 and 0.732, respectively, at optimal critical values of 543.12 ng/L and 7.50 points, respectively. The frequency of CAL in children with KD is high. NT-proBNP and Kobayashi scores are independent risk factors for the occurrence of CAL in children with KD, and they have good predictive performance for the diagnosis of CAL.
