目的分析人免疫缺陷病毒(HIV)感染者中出现的自身抗体和自身免疫现象。方法回顾性分析经间接免疫荧光法检测过自身抗体的HIV感染者的临床和相关实验室指标。结果共有19例HIV感染者检测了自身抗体,明确合并银屑病、溃疡性结肠炎、特发性血小板减少性紫癜(ITP)的患者各1例;8例出现风湿性症状,主要表现为原因不明的皮疹(5例)、关节疼痛(2例)和肌痛(1例)。10例自身抗体检测结果阳性,出现的自身抗体分别为抗核抗体(ANA)、抗平滑肌抗体(SMA)、抗线粒体抗体(AMA)、抗细胞骨架抗体(CS)、抗胃壁细胞抗体(AP—CA)。自身抗体阳性组患者的IgG和IgA水平明显高于自身抗体阴性组(P〈0.05)。结论HIV感染者中可检测出自身抗体,而且可以合并有自身免疫病或免疫亢进的现象。 相似文献

Objective To establish the enzyme-linked immunosorbent assay (ELISA) for the detection of serum alcohol dehydrogenase (ADH) antibody and evaluate its role in its diagnosis of autoimmune hepatitis( AIH ). Methods The reactivity between yeast ADH and human anti-ADH serum antibody was tested by Western blot analysis. ELISA was established using yeast ADH. The method was applied in serums of 67 AIH patients,94 primary biliary cirrhosis(PBC) patients, 199 chronic hepatitis B (CHB) patients, 132 chronic hepatitis(CHC) patients, 24 alcohol hepatitis disease(ALD) patients, 99 connective tissue disease(CTD) patients and 31 healthy individuals. The positive rate of ADH antibody in the patients and healthy individuals was measured. The χ2 test was used to compare the positive rates. Results The ELISA method for detecting human anti-ADH serum antibody was established successfully and the optimum reaction conditions were defined. Western blot showed that yeast ADH has cross reactivity with human anti-ADH antibody. The positive rate of anti-ADH antibody in the AIH group [59. 7% ,40/67 ] was higher than that in the normal control group(0,χ2 = 31. 271 ,P <0. 05), PBC group (6. 4% ,χ2 =54. 492,P <0. 05), CHB group( 14. 1% ,χ2 =54. 848,P <0. 05) ,CHC group(21.2% ,χ2 = 29.269,P<0.05), ALl) group ( 25. 0% ,χ2 =8.512,P <0.05)and CTD group ( 43. 4% ,χ2 =4.229, P <0. 05). Conclusions Compared with the PBC, CHB, CHC, ALD and CTD group, the anti-ADH antibody positive rate in the serums of AIH was significantly increased. The antibody may be helpful to the diagnosis of autoimmune hepatitis. 相似文献

药物性肝损伤患者的自身抗体分析 总被引:4,自引:1,他引:3
目的分析药物性肝损伤患者出现的自身抗体。方法对3000例经间接免疫荧光法及免疫印迹法进行过自身抗体检测的肝功能异常患者进行回顾分析。结果3000例肝功能异常患者中药物性肝损伤患者36例,占肝功能异常患者的1.2‰。36例药物性肝损伤患者中有29例自身抗体检测阳性,其阳性率分别为抗核抗体(ANA)66.7%(24/36)、抗平滑肌抗体(SMA)16.7%(6/36)、抗线粒体抗体(AMA)19.4%(7/36)、抗肝脏特异蛋白抗体(LSP)2.8%(1/36)、抗细胞骨架抗体(CS)19.4%(7/36)、抗胃壁细胞抗体(APCA)5.6%(2/36)、抗心肌抗体(AHRA)8.3%(3/36)。ANA、SMA和AMA阳性的拟诊药物性肝损伤患者进一步检测AMA亚型-M2、抗肝肾微粒体1(LKM-1)和抗可溶性肝抗原/肝胰抗原(SLA/LP),结果全部阴性;肝细胞型和胆汁淤积型、混合型自身抗体检测结果比较,其阳性率分别为95.2%(20/21),60.0%(9/15)。自身抗体阳性的药物性肝损伤患者其免疫球蛋白升高的比例比自身抗体阴性的要高,两者之间的差异有统计学意义(P<0.05)。结论药物性肝损伤患者血清中存在多种自身抗体但滴度较低;自身抗体(尤其是ANA、SMA和AMA)阳性的肝功能异常患者在拟诊药物性肝损伤时要注意自身免疫性肝脏疾病的排除。 相似文献
