Abstract:
Objective:To explore the influencing factors of HIV-1 DNA and its clinical value.Methods:The relationship between HIV-1 DNA and CD4 + T cell count, CD4/CD8, HIV viral load and subtype was analyzed in 304 patients with HIV/AIDS in order to explore the factors affecting HIV-1 DNA and the value of clinical application. Results:There was no statistically significant difference in HIV-1 DNA levels between the different CD4 + T cell level groups (Z=1.194, P>0.05). HIV-1 DNA levels were higher in the CD4/CD8≤0.5 group than in the CD4/CD8>0.5 group (Z=-2.788, P<0.01). HIV-1 DNA levels were higher in the HIV viral load >100 copies/ml group than in the ≤100 copies/ml group (Z=-2.953, P<0.01). HIV-1 DNA levels were higher in those with CD4 + T cell counts ≤200 at diagnosis than in those with CD4 + T cell counts >200 at diagnosis (Z=-2.175, P<0.05). HIV-1 DNA levels were higher in patients with CD4/CD8 ≤0.2 at diagnosis than in those with CD4/CD8 between 0.2 and 0.5, but there was no significant difference between the two groups (Z=-0.893, P>0.05). HIV-1 DNA levels were higher in both groups than in the CD4/CD8≥0.5 group (Z=-2.568, Z=-1.960, P<0.05). Higher HIV-1 DNA levels were found in people with an HIV viral load >100, 000 copies/ml at diagnosis than in people with an HIV viral load ≤100, 000 copies/ml at diagnosis (Z=-3.520, P<0.001). The level of HIV-1 DNA was higher in the CRF01_AE group than in the non-CRF01_AE group, and the difference was statistically significant (Z=-2.848, P<0.01). CD4/CD8 seemed to be a protective factor for HIV-1 DNA>500 copies/ml. (OR=0.214(95%CI: 0.056~0.822, P<0.05) Conclusion:CD4 + T lymphocyte count, CD4/CD8, viral load and subtype are factors that influence HIV-1 DNA levels, while HIV-1 DNA may be informative for immune status assessment and disease progression determination.
