Valproic Acid and Its Effects on HIV Latent Reservoirs

2014-08-27 03:46:10 | BioPortfolio

Summary

The purpose of this study is to examine whether the co-administration of valproic acid (Epival®), with highly active antiretroviral therapy (HAART) can reduce the size of HIV latent reservoirs in infected CD4 cells.

Description

Participants must be on HAART with a suppressed viral load (< 50 copies/ml) for at least the previous 12 months. They will be randomly assigned to one of two groups, one group will start the valproic acid right away at week 1 for 16 weeks, and the other group will wait until week 17 to add valproic acid to their treatment for 32 weeks. Subjects will be followed every four weeks for one year and evaluated by a variety of assays, all carried out using well-established methods, to assess the main outcome defined by changes in HIV reservoir size measured by the mean frequency of resting CD4 memory cells carrying HIV proviral DNA.

Medical and Biotech [MESH] Definitions

A fatty acid with anticonvulsant properties used in the treatment of epilepsy. The mechanisms of its therapeutic actions are not well understood. It may act by increasing GAMMA-AMINOBUTYRIC ACID levels in the brain or by altering the properties of voltage dependent sodium channels.

Inflammation of brain parenchymal tissue as a result of viral infection. Encephalitis may occur as primary or secondary manifestation of TOGAVIRIDAE INFECTIONS; HERPESVIRIDAE INFECTIONS; ADENOVIRIDAE INFECTIONS; FLAVIVIRIDAE INFECTIONS; BUNYAVIRIDAE INFECTIONS; PICORNAVIRIDAE INFECTIONS; PARAMYXOVIRIDAE INFECTIONS; ORTHOMYXOVIRIDAE INFECTIONS; RETROVIRIDAE INFECTIONS; and ARENAVIRIDAE INFECTIONS.

Viral infections of the leptomeninges and subarachnoid space. TOGAVIRIDAE INFECTIONS; FLAVIVIRIDAE INFECTIONS; RUBELLA; BUNYAVIRIDAE INFECTIONS; ORBIVIRUS infections; PICORNAVIRIDAE INFECTIONS; ORTHOMYXOVIRIDAE INFECTIONS; RHABDOVIRIDAE INFECTIONS; ARENAVIRIDAE INFECTIONS; HERPESVIRIDAE INFECTIONS; ADENOVIRIDAE INFECTIONS; JC VIRUS infections; and RETROVIRIDAE INFECTIONS may cause this form of meningitis. Clinical manifestations include fever, headache, neck pain, vomiting, PHOTOPHOBIA, and signs of meningeal irritation. (From Joynt, Clinical Neurology, 1996, Ch26, pp1-3)

Infections with viruses of the family PARAMYXOVIRIDAE. This includes MORBILLIVIRUS INFECTIONS; RESPIROVIRUS INFECTIONS; PNEUMOVIRUS INFECTIONS; HENIPAVIRUS INFECTIONS; AVULAVIRUS INFECTIONS; and RUBULAVIRUS INFECTIONS.

Exuberant inflammatory response towards previously undiagnosed or incubating opportunistic pathogens. It is frequently seen in AIDS patients following HAART.
