Statin Modulation of Monocyte/Macrophage Activation for HAND Treatment
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.

weeks of study entry) and willing to continue therapy for the duration of the study.
