Downmodulating Monocyte Activation for HIV-1 Associated Neurocognitive Disorders (HAND)
Not Provided

HIV associated neurological disorders (HAND), are a major problem even in ART treated people. HAND results from chronic inflammation which is largely attributed to expansion and activation of monocytes. These activated monocytes, some of which also carry virus to the brain, invade the CNS and release cytokines / chemokines resulting in further recruitment of monocytes, as well as release viral proteins which injure neurons and cause activation of other brain cells. Persistent monocyte/macrophage activation is thus a potential critical target for adjunctive therapy to treat or prevent HAND. The investigators therefore propose to study the effects of a statin drug (Atorvastatin), which has anti-inflammatory functions, on the monocyte activation status in vitro and in ART treated HIV+ individuals.

The investigators objectives are based on the hypothesis that Atorvastatin treatment will reduce the inflammatory and activated phenotype and function of monocytes which have been linked to HIV associated neuropathogenesis and occur in HIV infected subjects despite ART. In this study the investigators propose to

  1. determine how Atorvastatin modulates monocyte activation, intracellular signaling pathways and functions implicated in the pathogenesis of HAND in vitro
  2. define the effect of Atorvastatin on monocyte activation in HIV infected / ART treated subjects in a double blind, placebo controlled crossover study
  3. define gene expression patters of monocyte activation before and following statin treatment
  4. assess Atorvastatin effects on CNS immune activation markers and neurocognitive function in ART treated subjects.
