【摘要】:结核性脑膜炎(TBM)为结核病中最为严重的一种类型,目前我国有关结核病的诊断主要依据临床表现、影像学检查并结合痰涂片镜检或细菌培养或结核菌素皮肤试验(PPD皮试)。然而,由于常规细菌学检查方法灵敏性较差,对TBM的早期诊断不具明显临床意义。目前国内针对结核杆菌的研究较多,但尚缺乏对重要特异性抗原的定性研究,本研究中,我们应用酶联免疫吸附试验(ELISA)定量分析培养滤液蛋白10(CFP-10)和Ag85,以寻求对早期TBM诊断更具特异性的检测指标。 目的通过检测脑脊液中CFP-10、Ag85的水平来探讨二者对早期结核性脑膜炎的临床诊断价值。 方法选择2010年3月-2011年9月在吉林大学白求恩第一医院神经内科住院或门诊就诊的86例患者。(1)TBM组:结核分枝杆菌感染30例,男性19例,女性11例;年龄17~71岁,平均(42.33±12.58)岁。所有患者均于发病早期入院,临床表现为头痛、发热,伴恶心、呕吐、精神行为异常、肢体瘫痪,以及颈项强直、病理征阳性,严重者伴意识障碍、脑疝形成等症状与体征。其中7例头部CT或MRI检查显示脑积水,9例胸部CT检查发现肺结核。30例患者中22例经3~4周抗结核药物治疗后病情明显好转,2例病情危重者放弃治疗。(2)非TBM颅内感染组:病毒性脑膜炎患者27例,男性11例,女性6例;年龄16~67岁,平均(26.35±14.67)岁。以头痛、发热为首发症状,查体有颈项强直,不伴有其他神经系统体征;腰椎穿刺脑脊液检查仅白细胞计数轻度升高,蛋白定量于正常值范围或仅轻度升高;影像学检查无异常发现。(3)对照组:29例患者,男性13例,女性16例,年龄19~61岁,平均(34.18±15.24)岁。就诊时以头痛为主诉,体格检查未发现神经系统阳性体征,脑脊液及相关检查各项指标均于正常值范围。 结果TBM组患者脑脊液CFP-10水平经正态性检验,呈偏态分布,最小检测值为0.047、最大值为2.586pg/mL,平均水平0.743pg/mL;而非TBM颅内感染组和对照组均为正态分布,其脑脊液CFP-10平均水平分别为(0.024±0.013)pg/mL和(0.020±0.013)pg/mL。TBM组患者脑脊液CFP-10水平高于非TBM颅内感染组和对照组,且差异具有统计学意义(t=11.245,,P=0.000,t=11.245,t=12.614,P=0.000);但非TBM颅内感染组与对照组之间差异无统计学意(t=1.128,P=0.253)。 TBM组患者脑脊液Ag85水平呈偏态分布,最小检测值为0.747pg/mL、最大检测值为27.841pg/mL,平均测值为1.096pg/mL非TBM颅内感染组和对照组呈正态分布,Ag85平均水平分别为(0.544±0.103)和(0.523±0.105)pg/mL]。TBM组脑脊液Ag85水平高于非TBM颅内感染组和对照组,差异有统计学意义(t=10.769,P=0.000t=11.976,P=0.000);而非TBM颅内感染组与对照组之间差异无统计学意义(t=0.980,P=0.329)。 结论检测脑脊液中CFP-10、Ag85的水平可以辅助TBM的早期诊断
[Abstract]:TB meningitis ( TBM ) is one of the most serious types of tuberculosis . At present , the diagnosis of tuberculosis in China is mainly based on clinical manifestation , imaging examination and combined with sputum smear microscopy or bacterial culture or tuberculin skin test ( PPD skin test ) . However , due to the poor sensitivity of routine bacteriological examination method , there is no significant clinical significance for the early diagnosis of TBM . In the present study , we used enzyme linked immunosorbent assay ( ELISA ) to quantitatively analyze the filtrate protein 10 ( cfp - 10 ) and Ag85 , so as to find more specific detection index for early TBM diagnosis .

Objective To evaluate the clinical diagnostic value of the two methods for early tuberculous meningitis by detecting the level of the concentration of CFp - 10 and Ag85 in cerebrospinal fluid .

Methods From March 2010 to September 2011 , 86 patients were admitted to the First Affiliated Hospital of Bethune First Affiliated Hospital of Jilin University . ( 1 ) TBM group : 30 cases of Mycobacterium tuberculosis infection , 19 males and 11 females ;
All patients were admitted to the hospital at the age of 17 - 71 years , average ( 42.33 卤 12.58 ) years old . All patients were admitted to the hospital in the early stage . The clinical manifestations were headache , fever , nausea , vomiting , abnormal mental behavior , limb paralysis , and cerebral hernia formation . Among them , 22 of the 30 patients were treated with anti - tuberculosis drugs for 3 锝
