无症状期艾滋病HIV感染者CD_4^+ CD_8^+T淋巴细胞检测结果分析

Analysis on Testing Results of CD_4^+ CD_8^+T Lymphocyte of AIDS HIV Carrier without Symptoms

目的分析本地区人类免疫缺陷病毒(HIV)感染者免疫力被破坏情况,制订相应的艾滋病(AIDS)防治方案。方法对1344例无症状HIV感染者进行CD+4、CD+8T淋巴细胞检测。结果发现18例免疫力极度低下(CD+4<30个/mm3)的处于无症状期的HIV感染者,其CD+8T淋巴细胞值≥(400～800个/mm3)。结论无症状的HIV感染者中存在着免疫力极度低下者,由于高水平的CD+8T淋巴细胞的抗病毒作用而使之处于无症状期,但其免疫系统已严重受损,任何机会性感染都会诱发他们发展为AIDS。测定其CD+4、CD+8T淋细胞作为预见HIV感染状态和进展为AIDS的重要参考指标,具有不可替代的作用。

Objective To know the level which the HIV patients immunity is destroyed in the local area and thus make corresponding schemes to prevent and cure AIDS. Methods Test the CD+_4、CD+_8T lymphocyte of the 1344 HIV patients who haven't got symptoms. Results Find out 18 cases without symptoms but with extremely low level of immunity (CD_4<30/mm3) .Their CD+_8 T lymphocyte value ≥(400~800/mm3). Conclusion Owing to the high level of CD+_8T lymphocyte, the HIV patients whose immunity is exremely low, still haven't got any symptom. But their immune system has already been destroyed severely. It is very likely for them to catch AIDS. By testing its CD+_4、CD+_8T lymphocyte,we can predict the infectious state of HIV and its progress of catching AIDS . As an important reference index, the function of the test is irreplaceable.
