Filter by:The study hypothesis is that cenicriviroc will improve cognition in HIV infected individuals with cognitive impairment. The investigators will study the effect of cenicriviroc on cognition in 24 subjects over a 24 week period.
The purpose of this study is to describe the radiologic findings on brain MRI after ferumoxytol administration in HIV-infected patients with cognitive impairment.
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 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) define the effect of Atorvastatin on monocyte activation in HIV infected / ART treated subjects in a double blind, placebo controlled crossover study
To determine the prevalence of HIV associated Neurological Disorder (HAND) in a population of HIV positive patients within a primary care setting compared with the HIV negative population. The investigators aim is to assess the use of optimal screening methods to assess HAND. For this the investigators will be comparing the performance of a group of persons who are HIV positive and a group of persons who are HIV negative to test their memory and concentration abilities over-time.
Activated monocytes play a key role in the pathogenesis of HIV-associated neurocognitive disorders (HAND). Individuals with HAND have expanded populations of activated monocytes. These monocytes are thought to emigrate into the CNS, where they produce neurotoxic proinflammatory factors, and also carry virus into the CNS. Statins are cholesterol lowering drugs with pleiotropic immunomodulatory / anti-inflammatory properties that are currently being explored for immunomodulation of T cell activation in several diseases, in addition to their established role to treat hyperlipidemia and atherosclerosis. The investigators in vitro data suggests that these drugs can downregulate monocyte activation patterns seen in HIV infection. No in vivo studies have yet been carried out to assess the effects of statins on the pro-inflammatory monocyte population in chronic HIV disease. This will be a pilot study of whether statin treatment will reduce the inflammatory monocyte phenotype and downregulate the inflammatory cytokines that have been linked to neuropathogenesis in HIV infection. If so, they may have potential as adjunctive therapy in HIV-associated neurological disease. The investigators propose to: - Determine the effect of Atorvastatin on peripheral blood monocyte populations in a 12-week pilot study in chronically HIV-infected people on HAART therapy. - Determine the relationship between changes in monocyte phenotype following Atorvastatin treatment, and soluble markers of activation/inflammation linked to neuropathogenesis, as well as activation status of T cells.
The purpose of this study is to see if adding stavudine (d4T) to anti-HIV drug regimens (with or without zidovudine, ZDV) can improve symptoms of AIDS Dementia Complex (ADC, problems involving the brain or spinal cord) in HIV-positive patients.
The purpose of this study is to see if it is safe to give multiple doses of CPI-1189 to HIV-infected, otherwise healthy, males. The study will also look at how CPI-1189 affects the levels of HIV, T cells (cells in the body that help fight infection), and three anti-HIV drugs (zidovudine, lamivudine, and indinavir) in the blood. Advanced HIV infection can cause AIDS dementia (brain damage due to HIV leading to losses of memory and muscle control). CPI-1189 may be able to postpone AIDS dementia or slow it down.
To evaluate the benefit of adding 1592U89 to current antiretroviral therapies for AIDS dementia complex and to assess the safety and tolerance of the treatment regimens.
The purpose of this pilot study is to evaluate the efficacy of Retrovir (AZT) in the treatment of AIDS-related dementia and various neuromuscular complications. HIV is both a lymphotropic and neurotropic virus which can affect both the central and peripheral nervous systems (CNS, PNS). There is evidence that the CNS and PNS may harbor the virus in a latent state, with the potential for continuous reinfection of other body systems. Therefore, effective therapeutic efforts against HIV infection should provide effective antiviral activity within the nervous system.
The purpose of this study is to determine the safety and effectiveness of memantine, an experimental drug, in improving AIDS dementia complex (ADC). The symptoms of ADC can be improved with zidovudine (ZDV). However, ZDV therapy has been associated with significant toxicities, and the effectiveness of ZDV seems to decrease during the second and third years of therapy. The effectiveness of other antiretroviral drugs as treatment for ADC is not known, so it is important to explore alternative therapies.
