艾滋病患者的肝脏病理学研究

A pathological study on liver tissues of patients with HIV infection

目的 观察艾滋病(AIDS)患者肝组织的病理改变。方法 对11例无症状人类免疫缺陷病毒 (HIV)感染者和3例 AIDS 患者肝活体组织检查(肝活检)以及12例尸体解剖肝脏进行组织学观察，采用 免疫组织化学对肝活检组织及尸体解剖肝组织中的HIV-1外膜蛋白 gp120和衣壳蛋门 p24抗原进行检测。结 果 14例肝活检组织中检测出巨细胞病毒感染1例，11例肝脏库普弗细胞和部分淋巴细胞中有 HIV-1外 膜蛋白 gp120或(和)衣壳蛋白 p24抗原表达，肝细胞呈阴性。尸体解剖肝组织中检出巨细胞病毒感染5例， 分枝杆菌及弓形虫感染各3例，HIV 1衣壳蛋白 p24抗原阳性5例。结论 AIDS 患者肝组织中存在 HIV 1 感染，活检肝组织病例中机会性感染的几率较低。在尸体解剖肝组织中，机会性感染较为多见，并常为全身 机会性感染的局部表现。

Objective To study the pathological changes of the liver tissues of patients with HIV infection. Methods 14 biopsy and 12 autopsy liver tissues were examined histologically. HIV-1 related antigen of outer membrane protein gp120 and capsid protein p24 were examined with their corresponding monoclonal antibodies by immunohistochemistry. Results In the biopsy group, cytomegalic virus （CMV） infection was found in one （1/14） case, outer membrane protein gp120 and/or capsid protein p24 antigen were detected in Kupffer cells and in some of the lymphocytes in 11 cases. All the hepatocytes were negative for outer membrane protein gp120 and capsid protein p24 antigens. In the autopsy group, there were 5 （5/12） cases of liver tissues with CMV infection and 5 cases each with mycobacterium and Toxoplasma gondii infection. Capsid protein p24 was detected in liver tissues in 3 cases. Conclusion There is HIV infection in liver tissues of patients with HIV. The rate of opportunistic infections in liver biopsy samples was lower than that in the autopsy liver tissues of patients with HIV.
