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.
In this open-label, multicenter, multinational study, ZDV is replaced with d4T in ZDV-containing regimens, or d4T is added to non-ZDV-containing regimens in 20 patients experiencing ADC. Patients are defined as having failed treatment if they progress by one ADC stage on the MSK (Memorial Sloan Kettering) rating scale on study (i.e., from Stage 1 to 2 or Stage 2 to 3). Patients are evaluated on a weekly basis until the dementia deterioration is confirmed to be caused by HIV-1. The effect of d4T-containing regimens is assessed for the following parameters: neurological status, survival, AIDS-defining conditions, CSF (cerebrospinal fluid) and plasma viral load, CSF and blood immunological markers, blood CD4 cell counts, and viral resistance. This study also assesses the pharmacokinetics of d4T in the CSF and in the blood.

To provide accurate and complete neurologic assessment of the course of the AIDS dementia complex in patients treated with zidovudine (AZT). The study will determine how frequently patient...
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 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 wi...
A Multicenter Placebo-Controlled Double-Blind Trial to Evaluate Azidothymidine (AZT) Treatment of the AIDS Dementia Complex and Central Nervous System (CNS) Human Immunodeficiency Virus (HIV) Infection
To test whether zidovudine (AZT) is useful as a treatment for the neurologic syndrome called AIDS dementia complex. To determine how long AZT takes to reach cerebral spinal fluid (CSF), ho...
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 ...
Lower limb neuropathic pain in HIV patients is a common manifestation of sensory neuropathy (HIV-SN), but can be seen in patients who do not meet standard definitions of HIV-SN. The drug stavudine is ...
The International HIV Dementia Scale (IHDS) was developed as a tool to detect HIV-dementia in both industrialized and resource-limited settings. Studies employing the IHDS have produced mixed results,...
Complex, well-formed, and detailed visual hallucinations (VHs) are among the core clinical features of dementia with Lewy bodies (DLB). We investigated the diagnostic value of VHs in different types o...
Reducing doses of antiretroviral drugs, including stavudine (d4T), may lower toxicity, while preserving efficacy. There are substantial concerns about renal and bone toxicities of tenofovir disoproxil...
The use of the HIV antiretroviral drug stavudine (d4T), a thymidine analogue, is associated with the development of mitochondrial toxicities such as sensory neuropathy (SN). Genetic variation in genes...
A prodromal phase of infection with the human immunodeficiency virus (HIV). Laboratory criteria separating AIDS-related complex (ARC) from AIDS include elevated or hyperactive B-cell humoral immune responses, compared to depressed or normal antibody reactivity in AIDS; follicular or mixed hyperplasia in ARC lymph nodes, leading to lymphocyte degeneration and depletion more typical of AIDS; evolving succession of histopathological lesions such as localization of Kaposi's sarcoma, signaling the transition to the full-blown AIDS.
Immunologic tests for identification of HIV (HTLV-III/LAV) antibodies. They include assays for HIV SEROPOSITIVITY and HIV SERONEGATIVITY; (ELISA, immunofluorescence, immunoblot, etc.) that have been developed for screening persons carrying the viral antibody from patients with overt symptoms of AIDS or AIDS-RELATED COMPLEX.
Neuronal growth factor and lymphokine product of lectin-stimulated T-cells which induces immunoglobulin secretion. Its amino acid sequence is partially homologous to the HIV envelope glycoprotein gp120, which may explain, in part, the pathogenesis of AIDS DEMENTIA COMPLEX. Closely related to PHOSPHOHEXOSE ISOMERASE; AUTOCRINE MOTILITY FACTOR and maturation factor.
A neurologic condition associated with the ACQUIRED IMMUNODEFICIENCY SYNDROME and characterized by impaired concentration and memory, slowness of hand movements, ATAXIA, incontinence, apathy, and gait difficulties associated with HIV-1 viral infection of the central nervous system. Pathologic examination of the brain reveals white matter rarefaction, perivascular infiltrates of lymphocytes, foamy macrophages, and multinucleated giant cells. (From Adams et al., Principles of Neurology, 6th ed, pp760-1; N Engl J Med, 1995 Apr 6;332(14):934-40)
