a patient is on highly active antiretroviral therapy (haart) for the treatment of hiv. what does the nurse know would be an adequate cd4 count to determine the effectiveness of treatment for a patient per year?

White blood cells called CD4 cells, sometimes referred to as CD4+ T cells, work to combat infection. One of the main factors determining the requirement for opportunistic infection (OI) prophylaxis is the CD4 cell count, which serves as a gauge of immunological function in HIV-positive patients.

An immunological cell that promotes the production of immune responses from killer T cells, macrophages, and B cells.

White blood cells and lymphocytes both fall under the category of CD4-positive T lymphocytes. known as a helper T cell.

Our body is vulnerable to opportunistic infections if your CD4 count is under 200. These infections are ones that the immune system can typically fight off on its own, but in cases where the CD4 count is low, the immune system is unable to do so.
