Women with HIV experience slower disease progression and maintain higher CD4 counts than men, suggesting a potential delay in initiating highly active antiretroviral therapy (HAART) for women.

Area of Science:

  • Immunology
  • Virology
  • Epidemiology

Background:

  • Gender influences disease progression and CD4 lymphocyte counts in HIV infection.
  • Understanding these differences is crucial for effective treatment strategies.

Purpose of the Study:

  • To investigate the impact of gender on HIV disease progression.
  • To determine if gender-based differences in CD4 lymphocyte counts persist throughout the course of HIV infection.

Main Methods:

  • Longitudinal modeling of CD4 lymphocyte counts in 221 female and 443 male HIV seroconverters.
  • Regression analysis for repeated measurements, analyzing data backward from AIDS onset and death.

Main Results:

  • Women showed marginally slower progression to AIDS and death before highly active antiretroviral therapy (HAART).

  • Women maintained higher CD4 counts at seroconversion, AIDS onset, and death compared to men.
  • CD4 count decline rates were similar, except for a steeper decline in men closer to AIDS.
  • Conclusions:

    • Gender differences in CD4 counts may indicate a delayed initiation of HAART in women, potentially by 12 months.
    • Revised treatment guidelines may be necessary to ensure women benefit equally from HAART.
