Periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis syndrome (PFAPA) is one of the autoinflammatory diseases of unknown etiology characterized by regularly recurrent fever episodes with attacks lasting 3–6 days every 3–8 weeks associated with at least one of the three cardinal clinical signs: aphthous stomatitis, pharyngitis, and cervical adenitis. Kawasaki disease (KD) is an acute, self‐limited systemic vasculitis that occurs predominantly in infants and young children. In most KD patients, i.v. immunoglobulin leads to a rapid amelioration of clinical symptoms and significantly decreases the risk of coronary artery aneurysms. Although the etiology of KD is still unknown, it was reported that innate immunity was activated in the patients. Described herein is a patient with PFAPA who developed KD. This is the first report of KD development in a PFAPA patient. The association between KD and PFAPA may represent a genetic predisposition to dysregulated innate immune response.  相似文献

川崎病是一种以全身性血管炎为病理基础的疾病,已成为儿童获得性心脏病的最常见疾病,但其病因和发病机制仍不明确。肠道菌群稳态对机体免疫系统成熟及免疫调节有重要作用,肠道菌群紊乱参与儿童多种炎症免疫性疾病。研究发现,川崎病患儿存在肠道菌群组成的改变,肠道菌群紊乱与川崎病的发生发展有关,可能通过肠道黏膜屏障功能障碍、免疫炎症反应、氧化应激、代谢产物作用等多种机制影响免疫系统的正常功能。该文将对肠道菌群与川崎病关系的研究进展进行综述。  相似文献

天然免疫缺陷是原发性免疫缺陷病的一种.根据最新文献报道,天然免疫缺陷病主要包括七种疾病,这些疾病发病的根本原因均为基因突变.其中三种疾病的病因与NF-кB信号通路受阻有关,而有两种疾病与一般原发性免疫缺陷病发病机制不同,患者被相关的病毒感染后才会诱导发病.天然免疫缺陷在原发性免疫缺陷病中占有较重要的位置,但是由于对此病的认识不足,临床上很多天然免疫缺陷的疾病无法确诊.  相似文献

目的 分析婴幼儿川崎病(Kawasaki disease, KD)急性期肠道菌群的构成、丰度及功能差异,探索肠道菌群在KD发病机制中的作用。方法 前瞻性选择2021年7—10月在首都儿科研究所附属儿童医院心血管内科住院的6例0~3岁KD急性期婴幼儿为KD组,选取同期体检的年龄、性别匹配的6例健康婴幼儿为健康对照组。采用宏基因组测序检测并比较两组婴幼儿粪便样本的菌群结构及功能差异。结果 两组样本肠道菌群在结构组成、多样性分析方面差异有统计学意义(P<0.05)。KD组婴幼儿肠道菌群中单核细胞增生李斯特菌(李斯特菌科、李斯特氏菌属)、鲁塞蒂双歧杆菌、海氏肠球菌、鸟肠球菌丰度高于健康对照组(|LDA|>2,P<0.05)。KD组中类固醇降解和细胞凋亡通路较健康对照组显著升高,而细菌分泌系统、硫代谢、丁酸甲酯代谢、苯甲酸降解、β丙氨酸代谢、α亚麻酸代谢等通路显著减低(|LDA|>2,P<0.05)。结论 0~3岁KD急性期婴幼儿肠道菌群在结构及多样性方面与健康婴幼儿相比均有显著差异,提示KD急性期存在肠道菌群紊乱,尤其是单核细胞增生李斯特菌、海氏肠球菌、鸟肠球菌可能通过类固醇降解及细胞凋亡参与KD的发病机制。  相似文献

川崎病(Kawasaki disease,KD)是好发于5岁以下儿童的急性全身性中小血管炎性综合征,其最严重的并发症是冠状动脉病变,可导致冠状动脉扩张、心肌梗死及猝死。已有研究报道,在KD急性期可出现与休克相关的严重临床表现,并可能涉及所有器官,称为危重症KD(severe Kawasaki disease,SKD),有时需要儿童重症监护病房的处理。虽然SKD患儿临床症状严重,但只要能精确诊断和快速治疗,大部分患者都能存活,且可没有任何后遗症。近年来,国内外学者对SKD的关注越来越多,基于此,我们将SKD作为研究对象,阐述其临床诊断和治疗的相关进展,以利于儿科临床医生精准判断和治疗相关疾病。  相似文献

目的 川崎病休克综合征(Kawasaki disease shock syndrome,KDSS)是川崎病(Kawasaki disease,KD)的一种严重并发症。主要表现为起病急性期出现低血压、血流灌注减低,严重可危及患儿的生命。本研究旨在通过对KDSS患儿的临床特征及血清白细胞介素(interleukin,IL)-6表达水平的分析,提高临床儿科医生对该病的认识,从而对其进行早期干预、减少并发症及降低病死率。 方法 应用回顾性病例对照研究方法,收集南京医科大学附属儿童医院住院治疗的25例KDSS患儿和无低血压表现的普通KD患儿临床资料,分析其临床特点、相关实验室指标及IL-6的表达水平。 结果 与普通KD患儿相比,KDSS患儿中年长儿多见,发热时间延长,多伴有严重的皮疹,心房钠尿肽水平高、炎症指标高,且更容易合并冠状动脉扩张及发生丙种球蛋白耐药。KDSS患儿急性期IL-6水平较普通KD患儿明显升高[(28.5±39.2)ng/mL比(226.8±102.9)ng/mL, P<0.05],KDSS患儿恢复期IL-6水平较急性期明显下降[(226.8±102.9)ng/mL比(5.6±1.7)ng/mL, P<0.05] ,差异均有统计学意义。 结论 KDSS临床多表现为急性期更严重的炎症反应和更高的冠状动脉扩张风险。年龄大、发热持续时间长、皮疹严重、炎症指标高、心房钠尿肽水平高可能是KDSS发生的危险因素。IL-6在KDSS中发挥重要作用,但IL-6阻断剂在KD及其并发症中的治疗作用有待进一步研究。  相似文献

不完全川崎病占全部川崎病患者的比例呈逐年上升趋势。因其临床表现各异、起病隐匿,且缺乏特异性的临床表现和实验室检查指标,很容易因漏诊或误诊错过最佳的丙种球蛋白治疗时间而导致冠状动脉扩张、冠状动脉瘤等心血管并发症的发生,甚至继发血栓形成或猝死事件。本文旨在介绍不完全川崎病的诊治要点,为临床提供参考。  相似文献

Pritnaiy immunodeficiency diseases can be divided into eight diseases, including defects in innate immunity. According to new literature,defects in innate immunity involves seven diseases which are all resulted from gene mutation. Three diseases have a correlation with NF-κB signaling pathway. Different from common primary immunodeficiency diseases, two diseases have a correlation with virus infection. Defects in innate immunity play an important role in primary immunodeficiency diseases. But it can't make a definite diagnosis because of incompletely understanding.  相似文献

川崎病休克综合征是川崎病的一种严重亚型,主要表现为血流动力学不稳定和组织低灌注。与无休克的川崎病相比较,其心血管并发症发生率高,如发生冠状动脉病变、二尖瓣反流和心肌收缩功能障碍的风险增高;并常伴有多脏器损害;容易对IVIG无反应。儿科医师应充分认识川崎病休克综合征的流行病学和临床特征,避免误诊、漏诊,早期识别、及时治疗对改善预后至关重要。  相似文献

目的 分析川崎病休克综合征(KDSS)的临床特点,提高临床医生的诊治水平及改善患儿预后。方法 回顾分析我院2013年1月至2017年4月住院的川崎病(KD)患儿共924例,其中KDSS患儿16例。随机选取同期住院的KD患儿30例为对照组。对比分析两组患儿的临床特点、实验室检查和治疗措施。结果 KDSS患儿男9例,女7例。平均年龄(3.95±2.56)岁。出现休克的平均时间(4.31±0.79)d。与KD组比较,KDSS组性别、年龄、发热持续时间差异无统计学意义(P>0.05)。KDSS患儿更容易出现腹痛、肝功能异常(包括转氨酶升高和黄疸)、蛋白尿、腹腔积液、肺炎、冠状动脉瘤和IVIG抵抗,住院时间更长(P<0.05)。KDSS组的外周血白细胞计数[(28.42±10.46)×109/L比(20.34±7.57)×109/L]、中性粒细胞比例[(89.86±7.00)%比(73.14±13.91)% ]、超敏C-反应蛋白(mg/L)[181.95(141.58,218.00)比94.65(55.33,109.50)]、降钙素原(ng/ml)[9.64(4.85,12.07)比0.09(0.04,0.37)]、血清铁蛋白(ng/ml)[(388.12±241.75)比(169.86±95.14)]等炎症指标均高于KD组患儿(均P<0.05)。两组患儿的红细胞沉降率(mm/h)[(75.31±25.25)比(79.87±22.76)]、纤维蛋白原(g/L)[(6.17±1.45)比(6.03±1.47)]差异无统计学意义(P>0.05)。KDSS组患儿血小板计数[(655.50±226.98)×109/L比(549.93±119.15)×109/L]更高;而白蛋白(g/L)[(22.54±5.13)比(33.32±3.18)]、血钠(mmol/L)[(130.47±2.79)比(134.77±2.81)]、血钾(mmol/L)[(2.89±0.74)比(4.04±0.43)]水平及心脏彩超射血分数[(60.16±6.18)%比(64.81±3.71)% ]均更低(均P<0.05)。治疗过程中14例患儿进行了液体复苏,液体量平均(27.19±19.58)ml/kg。10例患儿使用了血管活性药物。6例患儿使用激素(甲基强的松龙)治疗。所有患儿均康复出院。结论 KDSS是KD的一种严重表现形式,患儿炎症指标升高更明显;更容易出现脏器功能损害,常见腹痛等消化道表现;抗休克治疗常需液体复苏并使用血管活性药物。  相似文献

A sibship with recurrent Kawasaki disease and coronary artery lesion   总被引:1,自引:0,他引:1  
Although epidemiologic studies of Kawasaki disease suggest an infectious etiology, the cause of this mysterious disease remains unclear. We describe the occurrence of five episodes of Kawasaki disease over a six-year period in three siblings. Two of the three children experienced recurrent Kawasaki disease and developed coronary artery lesions, which included giant coronary artery aneurysms in the youngest child. The non-contemporaneous occurrence of the disease in these three children emphasizes the importance of a genetic basis and/or environmental factors in the etiology of Kawasaki disease.  相似文献

Advances in Kawasaki disease   总被引:17,自引:0,他引:17  
Recent studies have increased our understanding of the etiopathogenesis of Kawasaki disease (KD). The inflammatory infiltrate in KD coronary artery aneurysms has been shown to consist of CD8 T lymphocytes, macrophages, and IgA plasma cells, consistent with an immune response to an intracellular pathogen with a mucosal portal of entry. The identification of an oligoclonal IgA response in the vascular wall and the detection of a KD-associated antigen in inflamed KD tissues using a synthetic antibody derived from KD oligoclonal IgA antibodies have provided new approaches to identification of the etiologic agent. Highly effective therapy has evolved for KD, even in the absence of identification of the etiologic agent. The existence of incomplete KD cases remains a significant diagnostic dilemma for the clinician. Conclusion: the development of a diagnostic test, more specific therapy, and ultimate prevention of this potentially fatal illness of childhood are dependent upon continued advances in determining the etiopathogenesis of this fascinating disorder.Abbreviations KD Kawasaki disease - IVIG intravenous immunoglobulin  相似文献
