Filter by:The primary objective of the study was to explore whether mefloquine can delay or stop progression of progressive multifocal leukoencephalopathy (PML) as measured by JC virus (human polyomavirus or JCV) deoxyribonucleic acid (DNA) levels in cerebrospinal fluid (CSF). The secondary objective of the study was to explore whether mefloquine can delay or stop progression of PML based on neurological deterioration, magnetic resonance imaging (MRI) measures of brain lesion evolution or the formation of new lesions, and mortality.
The primary purpose of this study is to assess whether hyperbaric oxygen treatment improves neurological function in patients who exhibit white matter hyperintensities on MRI examination. The secondary goal of this study is to determine if it is possible using MRI to discern a difference in perfusion of central nervous system tissue in regions of white matter hyperintensities after hyperbaric oxygen administration as compared to hyperbaric air.
Progressive multifocal leucoencephalopathy (PML) is a rare infectious disease of the brain, provoked by the JC virus. It usually occurs in subjects with impaired immune system as during HIV infection. To date, there is no specific antiviral treatment susceptible to cure PML. But it was shown in the setting of HIV-related PML, that combination antiretroviral therapy allows a restoration of the immune system and then might stop the progression of PML. The objective of this study is to appreciate the supplementary efficiency brought by an association of more powerful antiretroviral molecules including enfuvirtide on the evolution of PML. This research program will involve 30 patients in several centres in France. All the patients who will participate will receive enfuvirtide during 6 months in association with a combination of two or more potent antiretroviral drugs. The total duration of follow-up for a patient will be of 1 year.
The purpose of this study is to see if it is safe and effective to give topotecan through a vein to treat HIV-infected patients with PML, an opportunistic (AIDS-related) infection caused by a virus that infects brain tissue and causes damage to the brain and the spinal cord. Topotecan fights HIV and the JC virus (the virus that causes PML) in laboratory experiments.
The objective of this open-label study regimen is to make didanosine (ddI) available to patients with AIDS who are clinically deteriorating on zidovudine (AZT) and cannot enter the Phase II ddI programs due to protocol exclusion or geographic location.
To study the effectiveness of alpha interferon (IFN-A2b) and zidovudine (AZT) in treating progressive multifocal leukoencephalopathy (PML) as a complication of HIV-1 infection.
To compare the safety and efficacy of antiretroviral therapy (zidovudine plus either didanosine or dideoxycytidine) versus antiretroviral therapy plus intravenous cytarabine (Ara-C) versus antiretroviral therapy plus intrathecal Ara-C in the maintenance or improvement of neurological function over 6 months in HIV-infected individuals who have developed progressive multifocal leukoencephalopathy (PML). To compare the effect of these three treatment regimens on Karnofsky score and MRI studies. The effectiveness of Ara-C in the treatment of PML, caused by a human DNA papovavirus (designated JC virus) infection, has not been determined, although the most encouraging results have occurred with intrathecal administration of the drug.
The purpose of this study is to evaluate the safety, tolerance, and overall effectiveness of cidovir to treat PML in AIDS patients. PML is an opportunistic infection (HIV-associated, due to weak immune system) caused by a virus that attacks the brain. Cidovir has been used effectively to treat cytomegalovirus (CMV) of the eye. Cidovir could be an effective treatment for PML as well.
