Monocyte phenotype and function were measured in whole blood sampled from a current cohort of human immunodeficiency virus (HIV)-infected individuals attending a large, metropolitan, university-affiliated hospital.

There was no significant difference in the prevalence of CD16+ monocytes or the capacity of monocytes to ingest heat-killed Mycobacterium avium complex between these individuals and HIV-uninfected control subjects, regardless of viral load, current CD4+ T cell count, nadir CD4+ T cell count, or time since diagnosis of HIV infection. CD16+ monocyte prevalence was, however, elevated in patients not currently receiving antiretroviral therapy.

We conclude that HIV type 1 infection in the setting of highly active antiretroviral therapy is associated with normal monocyte function and phenotype.
