Active clinical trials for "AIDS Dementia Complex"

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 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.

This study tests whether galantamine (GAL) reduces HIV-related inflammation and cognitive deficits. In this double-blind placebo-controlled crossover study, HIV-infected individuals (N=120; 60 smokers and 60 non-smokers) will be randomized to 12 weeks of GAL or placebo, followed by a 4-week washout, then 12 weeks of GAL or placebo (arms switched). Outcomes are monocyte/macrophage and T cell activation and neurocognitive performance.

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.

To compare the safety and effectiveness of orally administered didanosine (ddI) with high dose orally administered zidovudine (AZT) in patients who develop or exhibit progression of the AIDS dementia complex (ADC) and who have not previously been intolerant to AZT at doses of up to 1000 mg/day. HIV-infected or AIDS patients may develop ADC which causes damage to the nervous system. ADC may be caused by some action of the AIDS virus on the nervous system, although similar problems can be caused by other infections because the AIDS virus lowers the body's ability to fight other infections. It is important to determine whether symptoms are due to ADC or to some other infection since treatment varies for different conditions. AZT has been shown to be beneficial to people with ADC although its effectiveness has only been studied in a small number of patients. Studies suggest that higher doses of AZT are more likely to be effective than standard doses in improving symptoms of ADC.

To assess the tolerability and safety of OPC-14117. To evaluate effects of OPC-14117 on cognitive function, quality of life, and activities of daily living.

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.

PRIMARY: To assess the safety of nimodipine in the treatment of HIV-Associated Motor / Cognitive Complex (formerly AIDS dementia complex). To assess the systemic or central nervous system toxicities (e.g., rash, headache, gastrointestinal symptoms, nausea, dyspnea, muscle pain or cramp, acne) of nimodipine. SECONDARY: To assess the efficacy of nimodipine in stabilizing the progression of HIV-Associated Motor / Cognitive Complex by improvement in neuropsychological test performance, peripheral neuropathy, or other neurologic manifestations. HIV-infected patients may develop a condition known as HIV-Associated Motor / Cognitive Complex (also known as AIDS dementia complex) that causes damage to the nervous system, particularly the brain and spinal cord. Evidence exists that nimodipine protects nerve cells in culture from injury by HIV. Although nimodipine has been used in patients with other neurological problems, its safety and effectiveness in halting the progression of HIV-Associated Motor / Cognitive Complex is not yet known.

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 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.
