Summary
Ejaculate exposure during unprotected anal intercourse (RAI-E) was linked to faster CD4 cell loss in HIV-positive men. This suggests sexually transmitted infections may accelerate HIV disease progression, advising caution against this practice.
Area of Science:
- Immunology
- Virology
- Public Health
Background:
- Human Immunodeficiency Virus (HIV) infection leads to a decline in CD4+ T-cells, a critical component of the immune system.
- Understanding factors that accelerate CD4+ T-cell loss is crucial for managing HIV disease progression.
Purpose of the Study:
- To investigate the association between ejaculate exposure through anoreceptive intercourse and the rate of CD4+ T-cell decline in HIV-seropositive men.
Main Methods:
- Longitudinal study of 937 HIV-seropositive men from the Multicenter AIDS Cohort Study (MACS).
- Data collected semiannually over four to ten visits, including self-reported behaviors and blood samples.
- Rapid CD4 cell loss defined as a 10% or greater decrease over two consecutive intervals.
Main Results:
- 42% of participants experienced rapid CD4 cell loss.
- Men reporting ejaculate exposure via anoreceptive intercourse (RAI-E) were over twice as likely to experience rapid CD4 cell loss compared to those without such exposure.
Conclusions:
- Ejaculate exposure through anoreceptive intercourse is associated with accelerated CD4+ T-cell loss in HIV-positive men.
- Sexually transmitted infections, often linked to ejaculate exposure, may be a contributing factor to faster HIV disease progression.
- HIV-infected individuals are advised to avoid unprotected anoreceptive intercourse.
