The effect of HIV infection and HAART on mitochondrion in peripheral monocytes / 中华检验医学杂志

ABSTRACT

Objective To evaluate the effect of HIV infection and highly active antiretroviral therapy (HAART) on mitochondrial function and mass in peripheral monocytes.Methods There were 14 ART-naive HIV-infected patients,14 NRTI treated HIV-infected patients and 12 healthy controls from Beijing Ditan Hospital.The mitochondrial membrane potential and mitochondrial mass in monocytes were analyzed by flow cytometry.Mitochondrial disturbances related to HIV infection and HAART in monocytes were analyzed.Results In ART-naive patients and NRTI-exposed patients,the levels of mitochondrial membrane potential in monocytes (77.74 ± 14.77,73.94 ± 12.87) were significantly lower than these in healthy controls (89.43 ±4.06) (P =0.032 8,P =0.002 6).The amount of mitochondrial mass in NRTI-exposed patients (3 329.0 ± 836.7) was significantly higher than that in healthy controls (2 075.0 ± 932.2) and that in ART-naive patients (2 592.0 ± 781.5) (P ＜ 0.05).Conclusions The abnormal of mitochondrial membrane potential and mitochondrial mass in monocytes from HIV-infected patients were related to HIV infection and the introduction of HAART.
