Immunologic and virologic events in early HIV infection predict subsequent rate of progression.

ABSTRACT:

Background

Variability in human immunodeficiency virus (HIV) disease progression cannot be fully predicted by CD4(+) T cell counts or viral load (VL). Because central memory T (T(CM)) cells play a critical role in the pathogenesis of simian immunodeficiency virus disease, we hypothesized that quantifying these cells in early HIV infection could provide prognostic information.

Methods

We measured expression of CD45RO, chemokine (C-C motif) receptor (CCR) 5, CCR7, CD27, and CD28 to enumerate naive and memory subsets in samples from recently infected individuals. We also quantified proliferation, CD127 expression, and cell-associated VL. Disease progression was compared across subgroups defined by these measurements, using Kaplan-Meier survival curves and multivariate Cox propo
