Dynamics of HIV tropism under suppressive antiretroviral therapy: implications for tropism testing in subjects with undetectable viraemia

摘要

Objectives The use of maraviroc as part of a simplification of antiretroviral therapy (ART) is hampered by the difficulty of assessing viral tropism in patients with undetectable viraemia. In this context, information on tropism might be obtained from testing either older stored viraemic sera collected before initiation of ART or current proviral DNA in peripheral blood cells.
