Despite the numerous intervention programmes, HIV still remains a public health concern with a high impact in Sub-Saharan Africa region. Oxidative stress has been documented in HIV subjects as viral infection promotes prolonged activation of immune system, hence, production of increased reactive oxygen species.
We studied 180 subjects. Of these, 60 were HIV-infected on antiretroviral therapy (ART), 40 were ART naïve HIV-infected and 80 were apparent healthy non HIV-infected subjects. The complete blood count was performed by automated hemoanalyzer, the CD4 T-cell count was performed by cyflow cytometer, while the antioxidant assay was performed using ELISA technique.
All evaluated parameters; glutathione (GSH), glutathione peroxidase (GPX), CD4 T-cell count, haemoglobin (Hb), total white blood cell count (WBC) and platelet count were significantly (P < 0.05) reduced in the HIV-infected subjects. All assessed parameters were found to be significantly (P < 0.5) reduced in the HIV-infected subjects that are ART naive when compared with those on ART. HIV-infected subjects with CD4 T-cell count < 200 cells/mm had significantly (P < 0.05) reduced values in all assessed parameters when compared to those with CD4 T-cell count ≥200 cells/mm. GSH and WBC were found to be significantly (P < 0.05) increased in the female HIV-infected subjects when compared with the male counterpart. Anemia prevalence of 74 and 33% were recorded for the HIV-infected and control subjects, respectively. Gender and ART treatment were found to be associated with anemia in HIV. Male HIV-infected subjects on ART were found to be more likely to have anemia.
Antioxidants; GSH and GPX were found to be significantly reduced in HIV infection. Further probe showed that the antioxidant status was improved in the HIV-infected group on ART.
尽管有许多干预计划,但 HIV 仍然是撒哈拉以南非洲地区的一个公共卫生关注点,对其影响很大。已经有文献记录表明,HIV 感染者存在氧化应激,因为病毒感染会导致免疫系统长期激活,从而产生更多的活性氧。
我们研究了 180 名受试者。其中,60 名为接受抗逆转录病毒治疗(ART)的 HIV 感染者,40 名为未接受 ART 的 HIV 感染者,80 名为明显健康的非 HIV 感染者。使用自动血细胞分析仪进行全血细胞计数,使用流式细胞仪进行 CD4 T 细胞计数,使用 ELISA 技术进行抗氧化剂检测。
所有评估参数,包括谷胱甘肽(GSH)、谷胱甘肽过氧化物酶(GPX)、CD4 T 细胞计数、血红蛋白(Hb)、总白细胞计数(WBC)和血小板计数,在 HIV 感染者中均显著降低(P<0.05)。与接受 ART 的 HIV 感染者相比,未接受 ART 的 HIV 感染者的所有评估参数均显著降低(P<0.5)。与 CD4 T 细胞计数≥200 个/立方毫米的 HIV 感染者相比,CD4 T 细胞计数<200 个/立方毫米的 HIV 感染者的所有评估参数值均显著降低(P<0.05)。与男性 HIV 感染者相比,女性 HIV 感染者的 GSH 和 WBC 显著升高(P<0.05)。HIV 感染者和对照组的贫血患病率分别为 74%和 33%。性别和 ART 治疗与 HIV 相关贫血有关。接受 ART 的男性 HIV 感染者更有可能患有贫血。
抗氧化剂 GSH 和 GPX 在 HIV 感染中显著降低。进一步研究表明,接受 ART 的 HIV 感染组的抗氧化状态得到了改善。
