“…Currently, HIV infection is considered one of the most serious infectious diseases in the world, which mainly causes damage or even defects of immune cells and organism function by infecting and destroying CD4 + T lymphocytes, eventually being complicated with various serious opportunistic infections and tumors [ 1 ]. Although the immunological mechanism of HIV infection in the body (for example, CD4 + T cell decline) has been partially established, the exact immune regulatory mechanism is unclear.…”

Objective. To investigate the quantity of CD4+T, CD4+T, CD8+T, and γδT cells in peripheral blood of HIV-infected/AIDS patients as well as to explore the possible role of CD4/CD8 ratio and γδT cells in the progression of HIV/AIDS, aimed at providing evidence for the diagnosis and treatment of AIDS. Methods. The quantity levels of CD3+T cells, CD4+T cells, CD8+T cells, and γδT cells in peripheral blood of 46 HIV-infected/AIDS patients and 30 healthy controls were detected by using flow cytometry. Results. The count of CD3+T, CD4+T, CD8+T, and γδT cells ( x ¯ ± s , A/μl) in the peripheral blood was 1183.64 ± 132.58 , 278.39 ± 122.38 , 863.13 ± 82.38 , and 22.53 ± 1.74 in the experimental group as well as 1456.46 ± 124.37 , 788.74 ± 189.67 , 569.61 ± 46.49 , and 10.96 ± 0.28 in the control group, respectively. The p values of the two groups were <0.005 after the t -test, revealing a statistically significant difference. The proportion of CD3+T, CD4+T, CD8+T, and γδT cells in total lymphocytes in the two groups ( x ¯ ± s , %) was 71.83 ± 5.37 , 13.39 ± 2.23 , 62.93 ± 5.81 , and 3.67 ± 0.87 in the experimental group, respectively. In the control group, the values were expressed as 66.72 ± 5.48 , 42.77 ± 3.38 , 31.41 ± 3.62 , and 1.73 ± 0.36 , respectively. After performing the t -test, p values in the two groups were <0.005 except CD3+T, with statistically significant differences. Besides, CD4/CD8 was 0.33 ± 0.11 in the experimental group and 1.48 ± 0.29 in the control group, t = 26.528 , p < 0.001 , exhibiting a significant statistical difference. Conclusion. HIV infection induces the activation and proliferation of CD8+T and γδT cells, contributing to the decrease of CD4+T cells, while CD8+T and γδT cells are involved in the immune response and tissue damage after HIV infection.

Populations around the world are rapidly ageing and effective treatment for HIV means women living with HIV (WLHIV) can live longer, healthier lives. HIV testing and screening programmes and safer sex initiatives often exclude older sexually active WLHIV. Systematically reviewing the literature to inform World Health Organization guidelines on the sexual and reproductive health and rights (SRHR) of WLHIV, identified four studies examining healthy sexuality among older WLHIV. In Uganda, WLHIV reported lower rates of sexual activity and rated sex as less important than men. In the United States, HIV stigma, disclosure, and body image concerns, among other issues, were described as inhibiting relationship formation and safer sexual practices. Sexual activity declined similarly over time for all women, including for WLHIV who reported more protected sex, while a significant minority of WLHIV reported unprotected sex. A single intervention, the "ROADMAP" intervention, demonstrated significant increases in HIV knowledge and decreases in HIV stigma and high risk sexual behaviour. WLHIV face ageist discrimination and other barriers to remaining sexually active and maintaining healthy sexual relationships, including challenges procuring condoms and seeking advice on safe sex practices, reduced ability to negotiate safer sex, physical and social changes associated with menopause, and sexual health challenges due to disability and comorbidities. Normative guidance does not adequately address the SRHR of older WLHIV, and while this systematic review highlights the paucity of data, it also calls for additional research and attention to this important area.
