摘要: 目的 :探讨检测血清特异性抗体诊断脑囊虫病的临床应用价值。方法 :采用 ELISA测定 282例初次CT平扫疑为脑囊虫病患者的血清囊虫抗体。所有病例均经强化 CT及 (或 ) MR、CSF分析、外科手术及实验性抗囊虫治疗作进一步诊断。其中 2 7例同时测定 CSF抗体。确诊为脑囊虫病者于服用阿苯达唑 1疗程后 ,或手术后 1个月复查血清抗体。结果 :2 82例中 ,确诊为脑囊虫病者 89例 ( 31.6% )。血清 EL ISA的特异性及敏感性分别为 89.1%69.7%。CSF- EL ISA的特异性为所测的 8例均为阴性 ,敏感性为 4 0 %。抗囊虫治疗后血清 EL ISA阳性 12例 ,手术后阳性 1例。囊虫的不同发育时期、部位及其数量可影响血清 EL ISA的阳性率及强度。CSF 细胞学变化与CSF-ELISA 存在明显的相关关系(等级相关检, r= 0. 724, P < 0. 01)。结论: 血清ELISA 是脑囊虫病诊断的一个有价值的补充手段。在囊虫病流行区, 该法可作为筛选工具。CT、MR 结合ELISA可大大提高诊断的准确性。试验性药物治疗具有诊断及治疗双重价值。

Abstract: AIM:To assess clinical value of detecting specific antibodies in sera by using
ELISA in diagnsis of neurocysticercosis.METHODS:Specific antibodies to cysticerci were examined
with ELISA in2 82 suspected neurocyticercosis cases having been experienced initial CT scan-
ning. All cases were further subjected to either of the following procedures:contrast en- hanced
CT,MR,CSF assay,surgery,anticysticercous therapy.For confirmed cysticercosis cases,albendazole2
0 mg/ (kg·d)× 1 0 was administered.RESULTS:Eighty-nine (31. 6% )persons were defined definitely as neurocysticercosis cases. The specificity and sensitivity of serum /ELISA for diagnosis of neurocysticercosis were 89. 1% and 69. 7% , respectively; and of CSF/ELISA , 8/8 and 8/20 (cases). The pathological aspects of the disease including location and number and duration of cysticerci would affect positive rate and intensity of serum/ELISA. The cytological changes in CSF revealed a significant correlation with CSF/ELISA results (P < 0. 01). CONCLUSION: ELISA used in detecting specific antibodies in patients’ sera is a promising supplementary tool in diagnosis of neurocysticercosis. It can be used to screen the disease in endemic area. Combined use of CT/MR and serum/EL ISA may make the diagnosis more accurate and reliable
