Survey and analysis on T lymph cell sub-group of individuals infected by HIV for 10 years

  Objective   To get a general idea about the existing T-lymph cells sub group o f the individuals infected by HIV for 10 years, and to work out a therapy, and to guide the highly active antiretroviral therapy.

  Methods   Absolute value of CD ₄, CD ₈ T-lymph cells in the peripheral blood of the infected individuals were detected with American FACSCount flow cytometer.

  Results   836 infected individuals were detected, 180 indivduals: CD ₄ T-lymph cells < 200/mm ³(21.53);656 individuals, CD ₄ T-lymph cells > 200/mm ³(78.7%), 779 indiriduals: CD ₄/CD ₈ < 1;57 individuals: CD ₄/CD ₈ > 1.

  Conclusion   CD ₄, CD ₈ T-lymph cells of individuals infected by HIV who survived for a long time remained normal within 10 years, but some of them dev eloped into AIDS.Owing to the high-level of CD ₈ T-lymphocyte, the HIV patients whose immunity was extremely low, still had not anysymptom.
