Abstract
In spite of the benefits of antiretroviral therapy (ART), immune activation remains higher
in HIV-positive individuals on ART than in non-infected persons.1 2
Furthermore, chronic inflammation in HIV-positive persons on ART has been linked to
poor morbidity and mortality outcomes.3 Individuals with HIV are at a higher risk for
end-organ diseases.4
What remains unknown is whether systemic inflammation itself is related to impaired
immune recovery following commencement of ART, and as a result, adverse clinical
outcomes. We intend to explore whether systemic inflammation prior to, and following
the commencement of, ART is a predictor of immune response in persons with HIV in
Manitoba. Using samples taken from prospectively enrolled HIV-positive individuals,
whom we enrolled prior to ART initiation and followed for one year, we will compare
levels of pro-inflammatory cytokines and markers of T cell activation before and after the
commencement of ART. We will then correlate levels of immune activation with
immune response and adverse clinical outcomes.
We hypothesize that higher levels of systemic immune activation will be associated with
suboptimal immune recovery on ART and adverse clinical outcomes, and that the
inflammation will be higher in protease based regimens.
An understanding of the factors involved in immune activation may help to improve
immune recovery and ultimately lead to the development of therapeutic adjuncts to ART.
