OBJECTIVE We investigated the dynamics of HIV RNA and HIV DNA levels after the commencement of raltegravir-based antiretroviral therapy (ART) in primary (PHI) and chronically HIV-infected (CHI) individuals (the PINT study). DESIGN We recruited 8 PHI and 8 CHI ART-naive individuals who commenced a 1-year combination regimen of Truvada and the integrase(More)
Viral blips, where HIV RNA plasma viral load (pVL) intermittently increases above the lower limit of assay detection, are a cause for concern. We investigated a number of hypotheses for their cause. We assessed HIV RNA, and total and episomal HIV DNA from 16 individuals commencing antiretroviral therapy (ART) consisting of raltegravir and(More)
UNLABELLED The latent HIV reservoir is a major impediment to curing HIV infection. The contribution of CD4(+) T cell activation status to the establishment and maintenance of the latent reservoir was investigated by enumerating viral DNA components in a cohort of 12 individuals commencing antiretroviral therapy (ART) containing raltegravir, an integrase(More)
BACKGROUND Eradication of HIV-1 is prevented by the formation of viral reservoirs in peripheral blood, lymphoid tissues and other sanctuary sites. In most patients, rebound upon treatment cessation is prompt. We assessed whether early treatment with raltegravir can impact on the formation of the viral reservoir. METHODS We conducted an open-label,(More)
BACKGROUND Current HIV-1 antiretroviral therapy (ART) greatly reduces virus replication but does not significantly affect the viral reservoir. Raltegravir, a recently introduced integrase inhibitor, could, at least theoretically, reduce residual viremia in patients on ART and affect the viral reservoir size. The aim of this study was to assess whether(More)
AIM HIV infection is associated with distortion of T-cell homeostasis and the IL-7/IL7R axis. Progressive infection results in loss of CD127+132- and gains in CD127-132+ CD4+ and CD8+ T-cells. We investigated the correlates of loss of CD127 from the T-cell surface to understand mechanisms underlying this homeostatic dysregulation. METHODS Peripheral and(More)
OBJECTIVES BIT225 (N-carbamimidoyl-5-(1-methyl-1H-pyrazol-4-yl)-2-naphthamide), a novel acyl-guanidine, is a novel antiviral drug that blocks Vpu ion channel activity and has anti-HIV-1 activity in vitro. The antiviral effect of BIT225 is most pronounced in cells of the myeloid lineage. With infected circulating monocytes and tissue-resident macrophages(More)
Memory CD4(+) T lymphocytes in peripheral blood that express integrins α4ß7 preferentially recirculate through gut-associated lymphoid tissue (GALT), a proposed site of significant HIV-1 replication. Tregs and activated CD4(+) T cells in GALT could also be particularly susceptible to infection. We therefore hypothesized that infection of these subsets of(More)
The concentration of airborne virulent R. equi is closely correlated with the prevalence of R. equi disease on endemically affected farms. Virulent R. equi is certainly aerosolised in association with dust, but foals are also an important source of airborne virulent R. equi as they breathe off high concentrations in exhaled air. Both clinically ill and(More)
