Progression to acquired immunodeficiency syndrome (AIDS) among persons infected with human immunodeficiency virus (HIV) varies considerably and may be influenced by factors such as age, smoking, number of male partners per year, and CD4 T-lymphocyte count. The loss of CD4 lymphocytes is known to be the dominant factor in the progression to AIDS. However, it is unclear whether the effect of the ...
Assessment of circulating CD4 count change over time in HIV-infected subjects on antiretroviral therapy (ART) is a central component of disease monitoring. The increasing number of HIV-infected subjects starting therapy and the limited capacity to support CD4 count testing within resource-limited settings have fueled interest in identifying correlates of CD4 count change such as total lymphocyt...
OBJECTIVES No randomized controlled trials have yet reported an individual patient benefit of initiating combination antiretroviral therapy (cART) at CD4 counts > 350 cells/μL. It is hypothesized that earlier initiation of cART in asymptomatic and otherwise healthy individuals may lead to poorer adherence and subsequently higher rates of resistance development. METHODS In a large cohort of HI...
OBJECTIVE To report the viral load and CD4 count in HIV-infected, antiretroviral naïve, first -time HIV-testers, not immediately eligible for treatment initiation by current South Africa treatment guidelines. DESIGN This was a cross-sectional study in a high-volume, free-of-charge HIV testing centre in Soweto, South Africa. METHODS We enrolled first time HIV testers and collected demographi...
Toll-like receptors (TLRs) are essential elements of the innate immune response to different infections including the infection with human immunodeficiency virus (HIV). Single nucleotide polymorphisms (SNPs) in TLRs such as TLR4 1063A/G and 1363C/T have been found to be associated with changes in CD4 count, viral load (VL), and disease progression during HIV infection. However, the association ...
CONTEXT Guidelines regarding the frequency of CD4 cell count and HIV RNA monitoring in HIV-infected patients vary, with recommended strategies ranging from every 2 to every 6 months. OBJECTIVE To determine optimal CD4 cell count and HIV RNA monitoring frequency in HIV-infected patients prior to antiretroviral therapy initiation. DESIGN Cost-effectiveness (CE) analysis using an HIV simulatio...
BACKGROUND The aim of this study was to assess the efficacy and safety of pegylated interferon (IFN) plus ribavirin (RBV) in human immunodeficiency virus (HIV) and hepatitis C virus (HCV)-coinfected patients with severe immunodeficiency in a clinical cohort. BACKGROUND. A total of 542 HIV-infected patients receiving treatment with pegylated IFN plus RBV from June 2001 through April 2007 were in...
It is unclear whether ongoing CD4 monitoring is needed following immunologic and virologic response to antiretroviral therapy (ART). We investigated the proportion of clients who achieved a virologic and immunologic response and then had a subsequent CD4 count <200 cells/μL despite continued virologic suppression. Included in this analysis were clients receiving ART through the Rakai Health Sci...
BACKGROUND Whether human immunodeficiency virus (HIV) seroconverters have been presenting with progressively lower CD4 cell counts over the course of the HIV epidemic is controversial. Additional data on whether HIV might have become more virulent on a population level (measured by post-seroconversion CD4 cell counts) may provide important insights regarding HIV pathogenesis. METHODS To deter...
