ABSTRACT
Objective:To investigate the relationship between the level of Apelin-13 and coronary artery lesion (CAL) in patients with Kawasaki disease (KD), and assess the predictive value of Apelin-13 for CAL in acute phase of KD.Methods:A total of 240 children with KD treated in Chengdu Women and Children′s Central Hospital from September 2017 to October 2019 were recruited, and were divided into KD with CAL (KD-CAL) group and KD without CAL (KD-NCAL) group.Thirty children with acute upper respiratory infection and 30 healthy children were recruited into the febrile control group and the healthy control group, respectively.Blood routine and serum levels of albumin, C-reactive protein (CRP), N-terminal pro-brain natriuretic peptide (NT-proBNP) and Apelin-13 were mea-sured in KD children prior to intravenous gamma globulin injection and after the diagnosis of children in the febrile control group and physical examination of children in the healthy control group.The clinical data of children in each group were compared, and the risk factors of KD complicated with CAL and the predictive value of Apelin-13 were determined by using receiver operating characteristic (ROC) curve and multiple Logistic regression analysis. Results:Apelin-13 and hemoglobin in children with KD were significantly decreased compared with those in the healthy control group and fever control group (all P<0.001). However, white blood cell(WBC) count, platelet count, CRP and NT-proBNP in KD group were significantly increased compared with those in the healthy control group and fever control group (all P<0.001). Serum albumin in KD children was significantly lower than that in the healthy control group ( P=0.004), and there was no difference when compared with the fever control group ( P=0.485). Apelin-13 and hemoglobin were significantly decreased in KD-CAL group compared with KD-NCAL group ( t=10.102, P<0.001; t=2.034, P=0.043), while NT-proBNP and CRP were significantly increased ( t=5.982, 3.728, all P<0.001). Multiple logistic regression analysis showed that Apelin-13 and NT-proBNP were independent predictors of CAL in KD.The ROC curve analysis showed that the cut-off value of Apelin-13 for predicting CAL was 2.99 μg/L, with an area under the curve (AUC) of 0.869 (95% CI: 0.820-0.909), sensitivity of 77.78% and specificity of 88.67%.While NT-proBNP cutoff value of 822 ng/L yielded sensitivity of 57.78% and specificity of 84.62% for predicting CAL with an AUC of 0.718(95% CI: 0.656-0.774). Conclusions:Apelin-13 plays a protective role in KD complicated with CAL, and could be used to predict CAL in the acute phase of KD.
ABSTRACT
Objective:To investigate the relationship of heart rate variability (HRV), heart rate deceleration capacity (DC) and intravenous immunoglobulin (IVIG)-resistant Kawasaki disease (KD) in children with the acute stage of KD.Methods:A total of 679 patients with KD in Chengdu Women and Children′s Central Hospital from August 2015 to May 2019 were selected.In healthy control group, 150 children obtained physical examination at the same time.Prospective cohort study was applied to analyze the data.According to the effect of initial IVIG treatment within 14 days, patients were divided into IVIG-sensitive group and IVIG-resistant group.General clinic information, HRV, DC, blood routine, liver function, cardiac troponin I (cTnI), N-terminal pro-B-type natriuretic peptide (NT-proBNP), high sensitivity C-reactive protein(hs-CRP) and erythrocytesedimentation rate (ESR) before initial IVIG treatment of the 2 groups were compared.Multivariate Logistic regression was applied to analyze the risk factors of IVIG-resistant KD. Results:Among 679 KD patients, 3 cases were lost, among the rest 676 cases, 586 cases were in IVIG-sensitive group, and 90 cases were in IVIG-resistant group.The HRV and DC indexes of IVIG-sensitive group and IVIG-resistant group were lower than those of the healthy control group, and the differences among the 3 groups were statistically significant (all P<0.05). Meanwhile, standard deviation of N-N intervals (SDNN) [(65.84±38.22) ms vs.(82.56±21.41) ms, P=0.004], and low frequency (LF)[ (192.59±114.10) ms 2vs. (258.18±162.75) ms 2, P=0.048] of IVIG-resistant group were lower than those of IVIG-sensitive group.White blood cell (WBC), platelets(PLT), hs-CRP, ESR, alanine aminotransferase(ALT), cTnI and NT proBNP in IVIG sensitive group and IVIG-resistant group were all higher than those in the healthy control group (all P<0.05). Further more, ESR[(90.32±37.91) mm/1 h vs. (65.81±25.34) mm/1 h, P=0.019], cTnI [(0.83±0.35) μg/L vs. (0.52±0.18) μg/L, P=0.037] and NT-proBNP [(854.64±293.02) ng/L vs. (584.95±177.11) ng/L, P=0.011] in IVIG-resistant group were higher than those of IVIG-sensitive group.Multivariate Logistic regression analysis demonstrated that SDNN ( OR=0.783, 95% CI: 0.0341-0.979, P=0.021), and NT-proBNP ( OR=1.195, 95% CI: 1.061-1.428, P=0.34) were independent risk factors for predicting IVIG-resistant KD. Conclusions:SDNN and NT-proBNP may be independent predictors of IVIG-resistant KD.
ABSTRACT
The application indications of imaging examination and cardiac catheterization in the diagnosis, treatment and follow-up of Kawasaki disease, especially cardiovascular sequelae, are further improved by the Japanese Circulation Society/Japanese Society for Cardiovascular Surgery 2020 Guideline on Diagnosis and Management of Cardiovascular Sequelae in Kawasaki Disease that also standardizes the long-term management program of Kawasaki disease in three different stages, namely, school, the adolescent/young adult and adulthood stage.In order to enhance the understanding of domestic medical staff with the latest knowledge, this paper focuses on the application progress of diagnostic imaging and cardiac catheterization in the diagnosis, treatment and long-term management of cardiovascular sequelae of Kawasaki disease in the guide.
ABSTRACT
Objective To investigate the correlation between red blood cell distribution width (RDW) and the cardiac function in children with acute heart failure,and to explore the clinical value in evaluating the degree of heart failure.Methods From July 2013 to October 2015,75 cases of children with acute heart failure who were hospitalized in Chengdu Women and Children's Central Hospital were collected and assigned as 3 groups.Heart function classification was done by using a modified Ross scoring system,and each group included 25 cases of class Ⅱ,Ⅲ,Ⅳ.Indices of red blood cell,haemoglobin,RDW,concentration of plasma N-terminal pro brain natriuretic peptide (NT-proBNP),and left ventricular ejection fraction (LVEF) were recorded.SPSS 17.0 software was statistically used for comparing cach index among groups and correlation analysis.Results Red blood cells and haemoglobin were not statistically different among groups (F =0.802,1.372,all P ＞ 0.05).RDW,NT-proBNP concentration and LVEF were significantly different among groups (F =31.388,29.300,x2 =56.952,all P ＜ 0.01),and significantly increased with the progression in the order of class Ⅳ group ＞ class Ⅲ group ＞ class Ⅱ group [RDW:(16.6 ± 1.3) ％ ＞ (15.4 ± 1.1) ％ ＞ (13.9-± 1.3) ％,NT-proBNP:(506.6 ± 190.2) ng/L ＞ (1 028.1 ± 356.8) ng/L ＞ (1 884.1 ± 358.6) ng/L,all P ＜ 0.01].According to LVEF =50％ as the cut-off point,children with acute heart failure were divided into LVEF decreased group and LVEF retention group,former group's RDW and NT-proBNP were significantly higher than the latter group[RDW:(16.7 ± 1.3)％ vs.(13.9 ±1.1)％,NT-proBNP:(1 787.4-±368.6) ng/Lvs.(657.4-± 291.1) ng/L,all P ＜0.01].According to NT-proBNP levels,the children with acute heart failure were divided into low,medium,and high NT-proBNP group,and RDW in the high NT-proBNP group[(17.3 ±0.9)％] was significantly higher than that of medium [(15.4 ± 0.7) ％],and that of low level group [(13.7 ± 1.2) ％] (all P ＜ 0.01).The correlation analysis between RDW,NT-proBNP as well as LVEF showed that RDW was significantly positive correlated with NT-proBNP (r =O.869,P ＜ 0.01),and negatively related with LVEF (r =-0.962,P ＜ 0.01).Conclusions RDW is closely related to the cardiac function in children with acute heart failure.RDW is increased with the aggravating of acute heart failure,which can indirectly reflect the NT-proBNP concentration and LVEF change and suggests that RDW can be used as a convenient and useful index monitoring the level of cardiac function in children with acute heart failure,and the assessment of the severity of acute heart failure.
ABSTRACT
Kawasaki disease (KD),also known as mucocutaneous lymph node syndrome,is an acute febrile rash illness with systemic small and medium vessel vasculitis in children.The long-term prognosis of KD is mainly determined by its cardiovascular complications,especially coronary artery lesion(CAL).CAL is harm to children's physical and mental health.Studies have suggested that the incidence of CAL is associated with infection of superantigens,cytomegalovirus and RNA viruses.Gene polymorphisms of costimulatory molecules,cytokines,chemokines,matrix metalloproteinase,inositol triphosphate kinase are also involved in occurance of CAL.Abnormal activation of the immune system,immune cell infiltration in the coronary arteries,coronary endothelial dysfunction,extracellular matrix degradation are the key steps of CAL through KD animal models and coronary artery from children died from KD.This review aims to discuss progress in etiology and pathogenesis of CAL in KD.
