They were divided into two groups: those with human immunodeficiency virus (HIV) and invasive fungal infection (IFI) (HIV + IFI) (n = 390) and those with HIV and no IFI (HIV + non-IFI) (n = 439). Another 200 healthy volunteers were enrolled as the control group. The numbers of NK cell subsets in each group were compared.Results: The level of NK cells, number of NK cells in all lymphocytes, proportions of CD56bright, CD56dim, and CD56dim NK cells in NK cells, and the level of CD56–CD16+ NK cells were significantly lower in the HIV + IFI group than in the HIV + non-IFI group and control group (P < 0.05). Moreover, CD4+ T, CD4+/CD8+, and NK cells were negatively correlated with HIV-RNA expression (P < 0.05).Conclusion: A combination of AIDS and deep fungal infection can change the immune status of a patient. This condition can be diagnosed early through the detection of NK cell expression.Keywords: natural killer cells, AIDS, deep fungal infection, CD56, expression
