Monocytes from human immunodeficiency virus (HIV) patients have an increased heterogeneity of phenotype and function. In a study of 120 HIV patients we have demonstrated that they have normal monocyte differential counts but that with progression of the disease an increasing proportion of monocytes show phenotypic and functional evidence for activation or maturation. A proportion of the monocytes are larger, with increased expression of CD11b, HLA‐DR, CD45 and CD16. Concomitantly there was increased expression of TNF‐α, high constitutive synthesis of PGE2 and high plasma IL‐6 levels. This suggested that there exist a more dynamic situation of recuitment, activation and maturation of peripheral blood monocytes driven by HIV infection which results in a broader phenotypic profile.
