川崎病患儿并发冠状动脉病变的危险因素分析

目的：探讨川崎病(KD)并发冠状动脉病变(CAL)的危险因素。方法：收集2006年1月至2012年1月间诊断为KD的527例患儿的临床资料,对15个可能与CAL发生有关的因素进行单因素和多因素logistic回归分析。结果：单因素分析显示,患儿年龄、性别、KD类型、大剂量丙种球蛋白（IVIG）治疗起始时间、对IVIG治疗的反应、使用糖皮质激素、发热持续时间及C反应蛋白等因素在合并和未合并CAL两组患儿中差异有统计学意义（P8岁、男性、非典型KD、IVIG治疗开始于发热后10 d 以上、对IVIG治疗无反应、发热持续时间>10 d为CAL发生的独立危险因素（OR分别为2.076、1.890、1.972、1.426、3.251、2.301、1.694,均P8岁）、男性、非典型KD、IVIG治疗起始时间较晚、对IVIG治疗无反应、发热持续时间较长是CAL发生的独立危险因素。     

川崎病并冠状动脉损害的危险因素

目的探讨川崎病(KD)并冠状动脉损害(CAL)的危险因素。方法收集1999年1月-2001年12月住院的145例KD患儿的临床资料,分析无CAL93例和CAL52例患儿的实验室检查资料及治疗、随访结果。结果无CAL组发热日程(8.7±3.4)d.血沉(79.5±34.6)mm/1h,CAL组发热日程(11.5±4.8)d,血沉(91.9±36.6)mm/1h,两组比较差异有显著性(P<0.01,0.05)。发病10d内接受静脉注射人血丙种球蛋白(IVIG)治疗患儿CAL发生率为18.8%(18/96),未予IVIG治疗患儿CAL发生率为69.4%(34/49),两者比较差异有显著性(P<0.001)。随访并CAL患儿38例,冠状动脉扩张20例均恢复正常;14例冠状动脉瘤中12例恢复正常,2例缩小;4例巨大冠状动脉瘤2例缩小,另2例超过2年仍未恢复。结论KD并CAL与热程过长及血沉显著增快密切相关,病程早期未予IVIG治疗的患儿并CAL的危险性明显增高,应用IVIG治疗对防治冠状动脉损害有重要作用。     

川崎病所致严重冠状动脉病变单中心队列研究

背景：川崎病（KD）所致严重冠状动脉病变（CAL）容易导致患儿发生冠状动脉事件或死亡,对远期预后及生存质量具有重要影响。 目的：总结分析伴严重CAL的KD患儿的中远期临床转归,为KD患儿长期随访管理及预后评估提供依据。 设计：队列研究。 方法：检索复旦大学附属儿科医院（我院）HIS系统,纳入2008年1月至2019年12月出院诊断为KD,经我院冠状动脉造影（CAG）确诊为KD所致严重CAL的＜18岁患儿。排除合并其他引起严重CAL和影响严重CAL预后疾病者。所有患儿在门诊及病房由资深心血管专科医生随访,均以药物治疗为基础,伴冠状动脉严重狭窄及心肌缺血的患儿经多学科讨论后予手术治疗。以确诊及随访期间出现心肌缺血、心肌梗死或死亡的患儿为预后不良组,反之则为预后良好组,观察出现不良预后及CAL的演变情况,分析不良预后的影响因素。 主要结局指标：不良预后发生情况和CAL的恢复情况。 结果：144例KD所致严重CAL患儿纳入本文分析。其中男117例（81.2%）,女27例;KD中位发病年龄2.2（1.0,4.5）岁,中位随访时间1.6（0,3.4）年,确诊为严重CAL时病程为5.0（3.0,21.3）月。144例KD所致严重CAL患儿共累及276支冠状动脉,56例（38.9%）累及单支冠状动脉,88例（61.1%）累及≥2支冠状动脉。发生巨大冠状动脉瘤（GCAA)122例,单支冠状动脉多发中小型冠状动脉瘤（CAA)8例,GCAA合并单支冠状动脉多发中小型CAA 6例,受累冠状动脉均狭窄8例;62例发生冠状动脉狭窄,其中冠状动脉闭塞31例。预后不良组54例（37.5%）,均存在心肌缺血,其中14例患儿缺血心肌处发生过有记录的急性心肌梗死,1例患儿因心肌梗死所致严重心力衰竭死亡。多因素分析结果显示,≥2支冠状动脉受累的患儿是单支冠状动脉受累的患儿发生不良预后风险的2.6倍（OR=2.602,95%CI：1.201~5.634）,合并冠状动脉狭窄的患儿是未合并冠状动脉狭窄的患儿发生不良预后风险的3倍（OR=3.055,95%CI：1.450~6.437）。共行179次CAG,114例（208支受累冠状动脉）行1次CAG,30例（68支受累冠状动脉）行≥2次CAG。68支受累冠状动脉首次确诊时,51支为GCAA,末次随访时好转率为4.0%;3支为多发中小型CAA,末次随访时好转率为66.6%;2支为单个中小型CAA,至末次随访均发生狭窄（狭窄程度约50%）;12支为狭窄,至末次随访时均未好转。 结论：GCAA是KD所致严重CAL的主要类型,且难以恢复,单支冠状动脉多发中小型CAA好转率较高。冠状动脉狭窄及多支冠状动脉受累是KD所致严重CAL患儿发生不良预后的影响因素。

Epidemiologic study of Kawasaki disease at a single hospital in Daejeon, Korea (1987 through 2000)

PURPOSE: We evaluated the epidemiology and a range of clinical characteristics in children with Kawasaki disease (KD) in one area of South Korea. METHODS: We retrospectively analyzed 506 medical records of children with KD, who were admitted at Daejeon St. Mary's Hospital from January 1987 through December 2000. RESULTS: The mean annual frequency was 36.1 +/- 11.1 cases per year. There were 55 cases (10.9%) in 1993, 50 cases (9.9%) in 1994 and 47 cases (9.3%) in 2000. There was a slightly higher occurrence in summer with no significant difference in seasonal frequency. Age distribution ranged from 2 months to 13 years of age (mean, 2.4 +/- 1.7 years) and 485 children (95.8%) were <5 years of age. The male-to-female ratio was 1.7:1. Of the total cases 0.6% was recurrent, whereas 0.4% occurred between siblings. There were no fatalities. For treatment aspirin alone (65 cases, 12.8%), divided dose intravenous immunoglobulin (IVIG) (400 to 500 mg/day for 4 to 5 days, 231 cases, 45.7%) and one dose IVIG (2.0 g/kg, 210 cases, 41.5%) were used. Between 1996 and 2000, 143 cases were treated with only one dose IVIG, and 21 cases (14.7%) showed coronary artery lesions (CAL). Among the 143 cases 22 cases (15.4%) were retreated with IVIG and/or steroid pulse therapy. The incidence of CAL in this group was 50.0%. CONCLUSION: In Daejeon, Korea, KD showed slight annual variations without seasonal differences. The rate of CAL in acute stage with one dose IVIG therapy (2 g/kg) was 8.3% in the IVIG responders.     

Coronary Arterial Calcification in Kawasaki Disease

The purpose of this paper is to describe the clinical characteristics and significance of the coronary arterial calcification due to Kawasaki disease (KD), based on our five patients. The coronary arterial lesions (CAL) were in segments 1, 2, 5, 6 and 11 according to the classification of the American Heart Association. The interval from the onset to the first appearance of coronary calcification was 17 months to 61 months. Progression of CAL into coronary arterial stenosis or myocardial infarction occurred in all five patients. In the comparative study between the patients with calcified CAL and those with non-calcified CAL, the maximal size of CAL of the former was 8 mm or larger in contrast with that of the latter (less than 8 mm). It is concluded that coronary arterial calcification is one of the important signs which suggest the presence of the advanced CAL in the follow-up of children with a history of KD.     

儿童川崎病并发髋关节滑膜炎临床特征及危险因素的病例对照研究

目的探讨川崎病(KD)并发髋关节滑膜炎(SH)的临床特点及其危险因素。方法回顾性纳入温州医科大学附属育英儿童医院KD数据库中2013年1月1日至2017年5月1日收治的连续KD住院患儿,以并发SH的KD患儿为SHKD组,未并发SH的KD患儿为KD组,分析KD患儿并发SH的可能危险因素。结果 1 038例KD患儿进入本文分析,SHKD组13例,KD组1 025例。①SHKD组男6例,女7例,平均发病年龄(35.5±15.3)月龄,病程中第1～17(9.1±4.2) d出现滑膜炎症状。双侧SH 9例,右侧SH 2例,左侧SH 1例,髋、膝关节滑膜炎1例。采用IVIG和阿司匹林治疗KD,1例出现冠状动脉扩张,1例出现休克,3例IVIG无反应。SH症状恢复时间1～10(4.0±2.4) d。②年龄、D-二聚体和IVIG无反应发生率在两组间差异有统计学意义(P分别为0.026、0.003和0.012)。③Logistic多因素回归分析显示,D-二聚体升高和IVIG无反应是KD并发SH的独立危险因素,OR值分别为1.151(95%CI:1.021～1.297)和12.2(95%CI:2.476～60.485)。结论SHKD临床表现以髋关节疼痛及下肢活动受限为主,症状轻,预后良好。D-二聚体升高和IVIG无反应是SHKD的独立危险因素。

川崎病冠状动脉病变严重程度临床分级及高危因素研究

目的 探讨基于临床分级的川崎病（KD）冠状动脉病变临床分级特点及不同危险等级冠状动脉病变的危险因素。方法 采用回顾性调查方法,对复旦大学附属儿科医院2000年1月至2011年6月住院且病史资料完整的1253例KD患儿,依据《川崎病冠状动脉病变的临床处理建议》提出的冠状动脉病变临床分级方法,分析冠状动脉病变临床分级及病变部位特点,采用单因素和多因素Logistic回归分析发生不同临床分级冠状动脉病变的危险因素。结果 （1）KD患儿急性期冠脉病变发生率为24.3%（304/1253）。根据冠状动脉病变临床分级进行分类,冠脉正常的Ⅰ级病例949例,占75.7%;Ⅱ级32例,发生率2.6%;Ⅲ级251例,发生率20.0%;Ⅳ级13例,发生率1.0%;Ⅴ级8例,发生率0.6%。（2）累及单支、双支、三支、四支冠状动脉者分别占冠状动脉病变患儿的42.4%、29.3%、16.1%和12.2%;发生病变的冠状动脉分支中左主干、左前降支、左回旋支、右冠状动脉病变分别占43.5 %、18.6%、6.8 %、31.1 %。（3）多因素Logistic回归分析显示,不完全型KD、CRP＞100 mg/L是Ⅱ级冠状动脉病变的独立危险因素;男性、年龄≤1岁、发热持续时间＞10 d、不完全型KD、ALB＜30 g/L是发生Ⅲ～Ⅴ级病变的独立危险因素。结论 （1）KD冠状动脉病变以Ⅲ级为最多见,占82.6%;V级最少见,占2.6%。（2）57.6%的冠状动脉病变累及二支或二支以上的冠状动脉。（3）KD冠状动脉病变部位以左冠状动脉主干最常见,其后依次为右冠状动脉、左前降支和左回旋支。（4）男性、年龄≤1岁、发热持续时间＞10 d、不完全型KD、ALB＜30 g/L是Ⅲ～Ⅴ级冠状动脉病变的独立危险因素。     

Immunohistochemical study of apparently intact coronary artery in a child after Kawasaki disease

BACKGROUND: Coronary arterial lesions (CAL) due to Kawasaki disease (KD) often show progressive intimal hyperplasia even many years after the disease. However, most patients have no CAL after the acute phase, and it is an important issue whether or not coronary arteries without CAL have significant intimal hyperplasia, and whether or not there is the potential for this to progress to stenosis and/or atherosclerosis. METHODS: The authors examined formalin-fixed specimens of the coronary arteries immunohistochemically, using antibodies against vascular growth factors (GFs), the receptors of transforming growth factor-beta (TbetaRs) and inducible nitric oxid synthesis (iNOS) in a KD patient without CAL, and also in four control patients: two with CAL due to KD and two without a history of KD. RESULTS: Vascular endothelial GFs, Platelet-derived growth factor-A (PDGF-A) and TbetaRs were expressed in the vascular smooth muscle cells of all patients. PDGF-A, transforming Gfbeta1 and iNOS were expressed in the intimal smooth muscle cells of the KD but not the normal coronary artery without a history of KD. The number of TbetaR-II-positive cells were fewer than TbetaR-I-positive cells in the intima of CAL due to KD, but the number was of both almost same in the intima of coronary artery without CAL after KD and in the normal coronary. CONCLUSION: The intact coronary artery 13 months after KD still showed the influence of the inflammation of KD. Although the authors speculate that the intimal proliferation will not continue beyond the acute phase, those patients may have a risk factor for atherosclerosis.     

The Fate and Observed Management of Giant Coronary Artery Aneurysms Secondary to Kawasaki Disease in the Province of Quebec: The Complete Series Since 1976

Most population-based series reporting on the coronary artery complications after Kawasaki disease (KD) originate from Japan. This study aimed to describe the complete series of KD patients from the province of Quebec in Canada, a predominantly Caucasian population. This retrospective case series was conducted by the Quebec Kawasaki Disease Registry, a multi-institutional collaboration reviewing 89.8 % of all KD cases identified by the Ministry of Health records of hospitalization for KD from the first recognized case in 1976 until 2008. This report describes the course of 38 patients (95 % Caucasians) with a diagnosis of giant coronary artery aneurysms, which represent 1.9 % of all reviewed cases and 26.2 % of those with a coronary aneurysm 5 mm or larger. The age at diagnosis was 5.52 ± 4.04 years, and the follow-up period was 9.26 ± 6.9 years. The KD diagnosis was retrospective at autopsy in two cases and via echocardiography in four cases. The overall freedom from coronary thrombi, coronary intervention, or death was respectively 63.9, 67.5, and 85.1 %. Five deaths occurred as follows: 21 days after onset of fever (2 cases), 1.8 months after onset of fever (1 case), 1 year after retrospectively presumed but previously undiagnosed KD (1 case), and 5.7 years after a KD diagnosis (1 case of sudden cardiac death). Percutaneous transluminal coronary revascularization was attempted in four cases (1 requiring cardiac transplantation), and two other cases underwent primary bypass graft surgery. Whereas this study investigated cases of KD with severe coronary sequelae in the Province of Quebec, larger collaborative studies should be conducted for further understanding of the disease in predominantly non-Asian populations.     

川崎病患儿血清MMP-9与TIMP-1质量浓度变化及其临床意义

目的探讨川崎病(KD)患儿血清基质金属蛋白酶-9(MMP-9)及其特异性组织抑制剂1(TIMP-1)质量浓度的变化在预测发生冠状动脉病变(CAL)风险中的临床意义。方法观察组为2003~2004年在四川大学华西第二医院与四川省人民医院住院的KD患儿32例,静脉注射丙种球蛋白(IVIG)前后各抽取患儿外周静脉血1次,同时抽取20名正常体检儿童(正常对照组)外周静脉血。ELISA双抗体法测定血清MMP-9与TIMP-1质量浓度。用二维超声心动图观察心脏冠状动脉病变。结果观察组患儿急性期血清MMP-9、TIMP-1质量浓度及MMP-9/TIMP-1比值均较正常对照组儿童显著增高(P<0.01);IVIG干预前CAL组患儿血清MMP-9质量浓度及血清MMP-9/TIMP-1显著地高于非CAL组患儿(P<0.01);IVIG干预后观察组患儿血清MMP-9质量浓度与MMP-9/TIMP-1显著降低(P<0.01);IVIG干预后CAL组患儿血清MMP-9质量浓度及血清MMP-9/TIMP-1仍显著高于非CAL组患儿(P<0.05),而后者MMP-9/TIMP-1基本降至正常儿童水平;观察组患儿血清TIMP-1质量浓度在IVIG干预前后无显著变化。结论MMP-9与TIMP-1可作为KD合并CAL的一种关联因素,动态监测血清MMP-9质量浓度和(或)MMP-9/TIMP-1比值对预测KD并发CAL具有较重要临床意义。     

川崎病丙种球蛋白耐药及冠状动脉损伤早期预测指标的研究进展

川崎病是急性全身性血管炎综合征,主要影响冠状动脉.该病的长期预后取决于冠状动脉病变程度.早期应用大剂量静脉丙种球蛋白可以减少冠状动脉病变,丙种球蛋白耐药者冠状动脉病变风险大,早期预测丙种球蛋白耐药及冠脉损伤、及时采取措施对改善预后意义重大.该文对川崎病丙种球蛋白耐药及冠状动脉损伤的预测指标作一介绍.     

川崎病丙种球蛋白治疗策略与心脏损害及冠状动脉病变的相关性研究(1998-2008上海地区调查报告)(英文)

目的 川崎病(Kawasaki disease,KD)是一种病因未明的全身血管炎性综合征,伴冠状动脉病变(coronary artery lesion,CAL);大剂量静脉注射丙种球蛋白(intravenous immunoglobulin,IVIG)治疗KD的临床疗效肯定,但目前IVIG的用法和用量尚存在争议.该研究主要为评价不同IVIG方法治疗.KD的效果,探讨最佳治疗方案.方法 由上海市儿科心血管学组制定统一的KD调查表,发放到上海提供儿科服务的50家医院.回顾性分析1998-2008年上海地区住院KD患者的临床资料.共收集完全符合要求的KD患者资料表格1682例,其中男性1064例(63.3%),女性618例(36.7%);发病年龄(2.57±2.33)岁(0.1～18.8岁).治疗KD的IVIG方案包括1 g/ks×1次、2 g/kg×1次、0.4～0.5 g/kg×5次、1 g/kg×2次、2 g/kg×2次及其他.采用SAS 6.12统计软件包进行统计分析,计数资料采用X2检验计算;计量资料数据以X-±s表示,采用t检验.结果 在KD病程的5～10 d应用IVIG有助于最大化降低KD患者的CAL发生率;所有IVIG的KD患者中,应用方案1g/kg×2次治疗者心脏损害、冠脉病变的发生率均为最低,差异有统计学意义(P<0.05).结论 在KD病程5～10 d以IVIG 1g/kg×2次的剂量,有助于最大化降低KD患者的CAL发生率.     

Endomyocardial Biopsy in Children with Kawasaki Disease

To study the histopathology of the myocardium in Kawasaki Disease (KD) with various coronary angiographic fmdings, right endomyocardial biopsy specimens were evaluated on 20 boys and 16 girls with this disorder. KD with coronary artery lesions (CAL) showed various histopathological abnormalities, such as myocellular hypertrophy in 44%, degeneration in 61%, interstitial fibrosis in 44% and endomyocardial changes in 22%. KD without CAL revealed myocellular hypertrophy in 44%, degeneration in 50%, disarray in 28% and interstitial fibrosis in 6%. As in patients with long-standing KD, more than three years after onset, myocardial changes such as myocellular hypertrophy, disarray and interstitial fibrosis persisted, it is suggested that cardiomyopathy may develop in some patients with KD.     

Intravenous γ-Globulin for Kawasaki Disease

We studied the effect of γ-globulin (IVGG) and aspirin (ASA) on the development of the coronary artery lesions (CAL) of Kawasaki disease (KD) in three different protocols. Within 29 days of the onset of KD the echocardiographic evidence of CAL had developed in 39–42% of the patients in the ASA group, but only in 13.7–20.8% of the patients treated with IVGG (200 or 400 mgγkgX5). In long-term follow-up observation of CAL of these patients the evidence of CAL in both the ASA and the IVGG group regressed gradually; however, the residual rate of CAL was significantly low in the IVGG group at all times up to 24 months after onset. These facts suggest that when using IVGG for KD, we should select a dose of intact γ-globulin, 1,000 mgγkg or more in total, to prevent the occurrence of CAL. We have demonstrated not only a significant reduction in the occurrence of CAL in patients treated with IVGG but a reduction in the residual rate of CAL for two years as compared with those treated by ASA.     

Epidemiologic picture of Kawasaki disease in Beijing from 1995 through 1999

OBJECTIVE: Kawasaki disease (KD) is supposed to be more common in the Asian race. The incidence in Japan is 10-fold higher than rates reported from western countries. This study sought to evaluate the epidemiologic picture of KD in Beijing and its suburbs. METHOD: A questionnaire form and diagnostic guidelines for KD were sent to all hospitals with pediatric inpatient beds throughout Beijing and its suburbs. Pediatricians were asked to review the medical records and report all patients with KD diagnosed during the 5-year period from January, 1995, through December, 1999. RESULTS: A total of 710 patients with KD were reported from 37 (95%) of 39 hospitals with pediatric inpatient beds. The incidences of KD for each year of the study were 18.2 (1995), 21.1 (1996), 18.6 (1997), 30.6 (1998) and 27.8 (1999) per 100,000 children <5 years of age. The male:female ratio was 1.7:1. The age at onset ranged from 1 month to 13.4 years (median, 2.3 years), with 85.2% <5 years old. The disease occurred more frequently in spring and summer and less frequently in autumn and early winter. Lymph node enlargement was the least common clinical sign, and its incidence decreased from 1995 to 1999. Cardiac abnormalities were found in 21.5% of patients and were more prevalent in patients diagnosed 10 days or longer after the onset. No patients died in the acute stage. CONCLUSION: The incidence of KD in Beijing is lower than that reported in Japan, similar to the incidence in the United States and higher than in other western countries. The age and gender distribution and increasing trend in incidence are similar to those in previous reports, but seasonal distribution is unique.
