第七节化脓性脑膜炎细菌性脑膜炎(bacterialmeningitis),简称化脑,是儿童期最严重的感染之一,具有高发病率、高病死率、临床症状多不典型和严重并发症的特点。
[ { "id": 0, "entity": "化脓性脑膜炎", "start_offset": 3, "end_offset": 9, "label": "dis" }, { "id": 1, "entity": "细菌性脑膜炎", "start_offset": 9, "end_offset": 15, "label": "dis" }, { "id": 2, "entity": "bacterialmeningitis", "start_offset": 16, "end_offset": 35, "label": "dis" }, { "id": 3, "entity": "化脑", "start_offset": 39, "end_offset": 41, "label": "dis" } ]
【病因学】化脑在0~2月龄内婴儿,其致病病原常反映母亲的带菌情况和婴儿的生活环境,常见病原有B族链球菌和革兰阴性肠杆菌等,偶尔也有流感嗜血杆菌b型(Hib)或不定型菌株。
[ { "id": 0, "entity": "化脑", "start_offset": 5, "end_offset": 7, "label": "dis" }, { "id": 1, "entity": "B族链球菌", "start_offset": 46, "end_offset": 51, "label": "mic" }, { "id": 2, "entity": "革兰阴性肠杆菌", "start_offset": 52, "end_offset": 59, "label": "mic" }, { "id": 3, "entity": "流感嗜血杆菌b型", "start_offset": 65, "end_offset": 73, "label": "mic" }, { "id": 4, "entity": "Hib", "start_offset": 74, "end_offset": 77, "label": "mic" } ]
在2月龄至12岁的儿童组中,其致病菌常是肺炎链球菌、脑膜炎双球菌或Hib。
[ { "id": 0, "entity": "肺炎链球菌", "start_offset": 20, "end_offset": 25, "label": "mic" }, { "id": 1, "entity": "脑膜炎双球菌", "start_offset": 26, "end_offset": 32, "label": "mic" }, { "id": 2, "entity": "Hib", "start_offset": 33, "end_offset": 36, "label": "mic" } ]
在美国,没有应用Hib疫苗之前,约70%小于5岁儿童的化脑是由Hib引起。
[ { "id": 0, "entity": "Hib疫苗", "start_offset": 8, "end_offset": 13, "label": "dru" }, { "id": 1, "entity": "化脑", "start_offset": 27, "end_offset": 29, "label": "dis" }, { "id": 2, "entity": "Hib", "start_offset": 31, "end_offset": 34, "label": "mic" } ]
另外,在一些有解剖结构缺陷或免疫功能缺陷的人群,少见病原引起脑膜炎的病例增加,如铜绿假单胞菌、金黄色葡萄球菌、凝固酶阴性葡萄球菌、沙门菌属和李斯特菌等。
[ { "id": 0, "entity": "解剖结构缺陷", "start_offset": 7, "end_offset": 13, "label": "sym" }, { "id": 1, "entity": "免疫功能缺陷", "start_offset": 14, "end_offset": 20, "label": "sym" }, { "id": 2, "entity": "脑膜炎", "start_offset": 30, "end_offset": 33, "label": "dis" }, { "id": 3, "entity": "铜绿假单胞菌", "start_offset": 40, "end_offset": 46, "label": "mic" }, { "id": 4, "entity": "金黄色葡萄球菌", "start_offset": 47, "end_offset": 54, "label": "mic" }, { "id": 5, "entity": "凝固酶阴性葡萄球菌", "start_offset": 55, "end_offset": 64, "label": "mic" }, { "id": 6, "entity": "沙门菌", "start_offset": 65, "end_offset": 68, "label": "mic" }, { "id": 7, "entity": "李斯特菌", "start_offset": 70, "end_offset": 74, "label": "mic" } ]
【流行病学及病原学】细菌性脑膜炎的重要危险因素:其一为年幼儿对感染的病原缺乏免疫力;其二为近期有致病细菌的携带。
[ { "id": 0, "entity": "细菌性脑膜炎", "start_offset": 10, "end_offset": 16, "label": "dis" } ]
(一)肺炎链球菌肺炎链球菌脑膜炎的发病率约为1/10万~3/10万,一生都可以感染此菌,2岁以下婴幼儿和老年人中的发病率最高。
[ { "id": 0, "entity": "肺炎链球菌肺炎", "start_offset": 3, "end_offset": 10, "label": "dis" }, { "id": 1, "entity": "链球菌脑膜炎", "start_offset": 10, "end_offset": 16, "label": "dis" } ]
其危险性同感染的肺炎链球菌血清型有关,血清型分布在不同国家和地区也不相同。
[ { "id": 0, "entity": "肺炎链球菌", "start_offset": 8, "end_offset": 13, "label": "mic" } ]
(二)流感嗜血杆菌流感嗜血杆菌是广泛寄居在正常人上呼吸道的微生物,在健康儿童中,约30%~80%都带有Hi,绝大多数是无荚膜不定型(NTHI),无致病性的,仅少数为有荚膜菌株,而侵袭性疾病大多数为Hib菌株引起。
[ { "id": 0, "entity": "流感嗜血杆菌", "start_offset": 3, "end_offset": 9, "label": "mic" }, { "id": 1, "entity": "流感嗜血杆菌", "start_offset": 9, "end_offset": 15, "label": "mic" }, { "id": 2, "entity": "上呼吸道", "start_offset": 24, "end_offset": 28, "label": "bod" }, { "id": 3, "entity": "荚膜菌株", "start_offset": 83, "end_offset": 87, "label": "mic" }, { "id": 4, "entity": "Hib菌株", "start_offset": 98, "end_offset": 103, "label": "mic" } ]
b型流感嗜血杆菌(Hib)带菌的高峰年龄主要在6个月~2岁半,然后很快下降,4岁后很少带菌。
[ { "id": 0, "entity": "b型流感嗜血杆菌", "start_offset": 0, "end_offset": 8, "label": "mic" }, { "id": 1, "entity": "Hib", "start_offset": 9, "end_offset": 12, "label": "mic" } ]
Hib的传播方式主要由呼吸道经空气、飞沫或经手传染,主要感染5岁以下的儿童,引起多器官、组织的侵袭性感染,其中占第一位而且危害最大的是脑膜炎。
[ { "id": 0, "entity": "Hib", "start_offset": 0, "end_offset": 3, "label": "mic" }, { "id": 1, "entity": "呼吸道", "start_offset": 11, "end_offset": 14, "label": "bod" }, { "id": 2, "entity": "手", "start_offset": 22, "end_offset": 23, "label": "bod" }, { "id": 3, "entity": "多器官、组织的侵袭性感染", "start_offset": 40, "end_offset": 52, "label": "sym" }, { "id": 4, "entity": "脑膜炎", "start_offset": 67, "end_offset": 70, "label": "dis" } ]
在美国未用此菌苗前,5岁以下儿童Hi脑膜炎发病率60/10万,死亡率为5%~10%,而由于中枢神经损伤所造成的后遗症发生率为30%~50%。
[ { "id": 0, "entity": "儿童Hi脑膜炎", "start_offset": 14, "end_offset": 21, "label": "dis" }, { "id": 1, "entity": "中枢神经", "start_offset": 45, "end_offset": 49, "label": "bod" }, { "id": 2, "entity": "中枢神经损伤", "start_offset": 45, "end_offset": 51, "label": "sym" } ]
近年来人们发现,由于耐药菌株的出现,尽管使用了有效的抗生素,仍有5%的患者死亡,30%的患者有中枢神经系统后遗症。
[ { "id": 0, "entity": "抗生素", "start_offset": 26, "end_offset": 29, "label": "dru" }, { "id": 1, "entity": "中枢神经系统", "start_offset": 47, "end_offset": 53, "label": "bod" }, { "id": 2, "entity": "中枢神经系统后遗症", "start_offset": 47, "end_offset": 56, "label": "sym" } ]
在我国,1943年樊培禄首次在成都报告了2例Hi脑膜炎,虽经磺胺治疗,但均未免于死亡。
[ { "id": 0, "entity": "Hi脑膜炎", "start_offset": 22, "end_offset": 27, "label": "dis" }, { "id": 1, "entity": "磺胺", "start_offset": 30, "end_offset": 32, "label": "dru" }, { "id": 2, "entity": "死亡", "start_offset": 40, "end_offset": 42, "label": "sym" } ]
1955年黄达枢报告浙江省儿童保健院2年中24例Hi脑膜炎,占该院(1952~1953年)收治化脓性脑膜炎149例的16.1%。
[ { "id": 0, "entity": "Hi脑膜炎", "start_offset": 24, "end_offset": 29, "label": "dis" }, { "id": 1, "entity": "化脓性脑膜炎", "start_offset": 47, "end_offset": 53, "label": "dis" } ]
同年,上海儿科医院100例化脑Hi占11%。
[ { "id": 0, "entity": "化脑Hi", "start_offset": 13, "end_offset": 17, "label": "dis" } ]
值得注意的是,此时报道的小儿细菌性脑膜炎中,原因不明者高达24%~38%。
[ { "id": 0, "entity": "小儿细菌性脑膜炎", "start_offset": 12, "end_offset": 20, "label": "dis" } ]
由于各种原因,以后的近30年国内几乎无Hi脑膜炎的文献可寻。
[ { "id": 0, "entity": "Hi脑膜炎", "start_offset": 19, "end_offset": 24, "label": "dis" } ]
1988年11月至1989年年底,北京儿童医院应用CIE荚膜多糖抗原检测方法,结合细菌培养,对北京儿童医院128例化脑患儿进行了病原学研究。
[ { "id": 0, "entity": "CIE荚膜多糖抗原检测", "start_offset": 25, "end_offset": 36, "label": "pro" }, { "id": 1, "entity": "化脑", "start_offset": 57, "end_offset": 59, "label": "dis" } ]
临床诊断为化脑的患儿只有4例培养出Hib,而抗原检测有37例Hib阳性,占全部小儿化脓性脑膜炎的28.9%。
[ { "id": 0, "entity": "化脑", "start_offset": 5, "end_offset": 7, "label": "dis" }, { "id": 1, "entity": "Hib", "start_offset": 17, "end_offset": 20, "label": "mic" }, { "id": 2, "entity": "抗原检测", "start_offset": 22, "end_offset": 26, "label": "pro" }, { "id": 3, "entity": "Hib阳性", "start_offset": 30, "end_offset": 35, "label": "sym" }, { "id": 4, "entity": "小儿化脓性脑膜炎", "start_offset": 39, "end_offset": 47, "label": "dis" } ]
在此基础上,采用相同的试验方法,我们于1990~1992年在合肥市(100万人口)组织13家医院15个科室进行了小儿化脑的病因学和流行病学监测。
[ { "id": 0, "entity": "小儿化脑", "start_offset": 56, "end_offset": 60, "label": "dis" } ]
所有患儿标本,细菌培养的阳性率仅13.3%,3种细菌抗原CIE监测的阳性率为90%。
[ { "id": 0, "entity": "细菌抗原CIE监测", "start_offset": 24, "end_offset": 33, "label": "pro" } ]
抗原检测发现,Hib占所有化脑的51.3%,其中58.8%为1岁以下,80.5%为5岁以下,5岁以下儿童Hib脑膜炎的发病率为10.4/10万。
[ { "id": 0, "entity": "抗原检测", "start_offset": 0, "end_offset": 4, "label": "pro" }, { "id": 1, "entity": "Hib", "start_offset": 7, "end_offset": 10, "label": "mic" }, { "id": 2, "entity": "化脑", "start_offset": 13, "end_offset": 15, "label": "dis" }, { "id": 3, "entity": "儿童Hib脑膜炎", "start_offset": 50, "end_offset": 58, "label": "dis" } ]
这一结果表明,尽管我国小儿Hib脑膜炎的发病率低于欧美国家菌苗使用前的发病率,它仍是我国小儿化脓性脑膜炎重要致病菌。
[ { "id": 0, "entity": "小儿Hib脑膜炎", "start_offset": 11, "end_offset": 19, "label": "dis" }, { "id": 1, "entity": "小儿化脓性脑膜炎", "start_offset": 44, "end_offset": 52, "label": "dis" } ]
(三)脑膜炎球菌性脑膜炎至今仍是全球性疾病,世界各地都有发病。
[ { "id": 0, "entity": "脑膜炎球菌性脑膜炎", "start_offset": 3, "end_offset": 12, "label": "dis" } ]
在非洲脑脊髓膜炎的流行,A群脑膜炎球菌仍是最常见的病原菌。
[ { "id": 0, "entity": "脑脊髓膜炎", "start_offset": 3, "end_offset": 8, "label": "dis" }, { "id": 1, "entity": "A群脑膜炎球菌", "start_offset": 12, "end_offset": 19, "label": "mic" } ]
此外,在巴西、马里、尼日利亚等地,C群脑膜炎球菌引起过大暴发。
[ { "id": 0, "entity": "C群脑膜炎球菌", "start_offset": 17, "end_offset": 24, "label": "mic" } ]
在智利、古巴、挪威等地,B群脑膜炎球菌也和一些暴发有联系,而且由这种血清群引起的病例最近几年在北美已明显增多了。
[ { "id": 0, "entity": "B群脑膜炎球菌", "start_offset": 12, "end_offset": 19, "label": "mic" } ]
【发病机制】细菌抵达脑膜可通过多种途径,如外伤或手术直接接种、淋巴或血流播散等。
[ { "id": 0, "entity": "脑膜", "start_offset": 10, "end_offset": 12, "label": "bod" }, { "id": 1, "entity": "外伤", "start_offset": 21, "end_offset": 23, "label": "dis" }, { "id": 2, "entity": "手术直接接种", "start_offset": 24, "end_offset": 30, "label": "pro" }, { "id": 3, "entity": "淋巴", "start_offset": 31, "end_offset": 33, "label": "bod" }, { "id": 4, "entity": "血流", "start_offset": 34, "end_offset": 36, "label": "bod" } ]
通常脑膜炎是由菌血症发展而来。
[ { "id": 0, "entity": "脑膜炎", "start_offset": 2, "end_offset": 5, "label": "dis" }, { "id": 1, "entity": "菌血症", "start_offset": 7, "end_offset": 10, "label": "dis" } ]
细菌多由上呼吸道侵入,先在鼻咽部隐匿、繁殖,继而进入血流,直接抵达营养中枢神经系统的血管,或在该处形成局部血栓,并释放出细菌栓子到血液循环中。
[ { "id": 0, "entity": "上呼吸道", "start_offset": 4, "end_offset": 8, "label": "bod" }, { "id": 1, "entity": "鼻咽部", "start_offset": 13, "end_offset": 16, "label": "bod" }, { "id": 2, "entity": "血流", "start_offset": 26, "end_offset": 28, "label": "bod" }, { "id": 3, "entity": "中枢神经系统的血管", "start_offset": 35, "end_offset": 44, "label": "bod" }, { "id": 4, "entity": "局部血栓", "start_offset": 51, "end_offset": 55, "label": "sym" }, { "id": 5, "entity": "血液", "start_offset": 65, "end_offset": 67, "label": "bod" } ]
由于小儿防御、免疫功能均较成人弱,病原菌容易通过血-脑屏障到达脑膜引起化脑。
[ { "id": 0, "entity": "血", "start_offset": 24, "end_offset": 25, "label": "bod" }, { "id": 1, "entity": "脑", "start_offset": 26, "end_offset": 27, "label": "bod" }, { "id": 2, "entity": "脑膜", "start_offset": 31, "end_offset": 33, "label": "bod" }, { "id": 3, "entity": "化脑", "start_offset": 35, "end_offset": 37, "label": "dis" } ]
婴幼儿的皮肤、黏膜、肠胃道以及新生儿的脐部也常是感染侵入门户。
[ { "id": 0, "entity": "皮肤", "start_offset": 4, "end_offset": 6, "label": "bod" }, { "id": 1, "entity": "黏膜", "start_offset": 7, "end_offset": 9, "label": "bod" }, { "id": 2, "entity": "肠胃道", "start_offset": 10, "end_offset": 13, "label": "bod" }, { "id": 3, "entity": "脐部", "start_offset": 19, "end_offset": 21, "label": "bod" } ]
鼻窦炎、中耳炎、乳突炎既可作为病灶窝藏细菌,也可因病变扩展直接波及脑膜。
[ { "id": 0, "entity": "鼻窦炎", "start_offset": 0, "end_offset": 3, "label": "dis" }, { "id": 1, "entity": "中耳炎", "start_offset": 4, "end_offset": 7, "label": "dis" }, { "id": 2, "entity": "乳突炎", "start_offset": 8, "end_offset": 11, "label": "dis" }, { "id": 3, "entity": "脑膜", "start_offset": 33, "end_offset": 35, "label": "bod" } ]
颅骨外伤、骨折的并发症,特别是那些涉及鼻窦的骨折,更可形成颅内与外界的直接通道,成为细菌侵入的门户。
[ { "id": 0, "entity": "颅骨外伤", "start_offset": 0, "end_offset": 4, "label": "dis" }, { "id": 1, "entity": "骨折", "start_offset": 5, "end_offset": 7, "label": "dis" }, { "id": 2, "entity": "鼻窦的骨折", "start_offset": 19, "end_offset": 24, "label": "dis" }, { "id": 3, "entity": "颅内", "start_offset": 29, "end_offset": 31, "label": "bod" } ]
先天性免疫球蛋白缺陷,细胞免疫缺陷或联合免疫缺陷,均影响婴儿预防感染的能力,容易发生严重感染乃至脑膜炎。
[ { "id": 0, "entity": "先天性免疫球蛋白缺陷", "start_offset": 0, "end_offset": 10, "label": "sym" }, { "id": 1, "entity": "细胞免疫缺陷", "start_offset": 11, "end_offset": 17, "label": "sym" }, { "id": 2, "entity": "联合免疫缺陷", "start_offset": 18, "end_offset": 24, "label": "sym" }, { "id": 3, "entity": "严重感染", "start_offset": 42, "end_offset": 46, "label": "sym" }, { "id": 4, "entity": "脑膜炎", "start_offset": 48, "end_offset": 51, "label": "dis" } ]
具有大量荚膜的细菌在血流中生存力加强,在缺乏免疫力的年幼儿中,血清低浓度的抗荚膜IgM与IgG抗体、血清备解素、血清补体成分如C19、C3和C5缺乏或减少,都影响对细菌有效的调理吞噬作用,使其容易发生脑膜炎。
[ { "id": 0, "entity": "血流", "start_offset": 10, "end_offset": 12, "label": "bod" }, { "id": 1, "entity": "脑膜炎", "start_offset": 100, "end_offset": 103, "label": "dis" } ]
细菌通过血-脑屏障进入脑脊液循环,因为脑脊液中的补体、抗体浓度明显低于血液循环,细菌可迅速繁殖,而化学趋化因子、肿瘤坏死因子、白细胞介素-1、前列腺素E和其他细胞因子或炎性介质的局部产生引起了局部炎症,细菌的细胞壁成分也可引起强烈的炎症反应。
[ { "id": 0, "entity": "血", "start_offset": 4, "end_offset": 5, "label": "bod" }, { "id": 1, "entity": "脑", "start_offset": 6, "end_offset": 7, "label": "bod" }, { "id": 2, "entity": "脑脊液", "start_offset": 11, "end_offset": 14, "label": "bod" }, { "id": 3, "entity": "脑脊液", "start_offset": 19, "end_offset": 22, "label": "bod" }, { "id": 4, "entity": "补体", "start_offset": 24, "end_offset": 26, "label": "bod" }, { "id": 5, "entity": "抗体", "start_offset": 27, "end_offset": 29, "label": "bod" }, { "id": 6, "entity": "血液", "start_offset": 35, "end_offset": 37, "label": "bod" }, { "id": 7, "entity": "局部炎症", "start_offset": 96, "end_offset": 100, "label": "sym" }, { "id": 8, "entity": "强烈的炎症", "start_offset": 113, "end_offset": 118, "label": "sym" } ]
继而,炎症造成白细胞浸润、血管通透性增加、血管闭塞,破坏了血-脑屏障。

关于抗生素选择、使用方法应注意以下几点:①患儿年龄对抗生素选择有一定的指导意义:如年长儿童患流感杆菌脑膜炎较少;新生儿化脑大多数是肠道革兰阴性杆菌或链球菌所致,故应选择对这些细菌有效的药物;②保证药物在脑脊液中达到有效浓度:首先应选用易于透过血-脑屏障的药物,使脑脊液中抗生素浓度超过抑菌浓度10倍以上;③鞘内注射:如果选用的药物能很好通过血-脑屏障,原则上不需鞘内注射,以免出现不良反应及增加病儿痛苦;④脑室内注药:由于存在血-脑屏障及脑脊液单向循环,对并发脑室膜炎患儿,有人主张脑室注药以提高疗效。
