BACKGROUND Viral load testing is considered the gold standard for monitoring HIV treatment; however, given its high cost, some patients cannot afford viral load testing if this testing is not subsidized. Since foreign aid for HIV/AIDS in Vietnam is rapidly decreasing, we sought to assess willingness to pay (WTP) for viral load and CD4 cell count tests among HIV-positive patients, and identified...
www.thelancet.com/hiv Vol 3 November 2016 e507 WHO and UNAIDS have recommended treatment as pre vention for the global elimination of HIV. Treatment suppresses an individuals’ viral load, making them less infectious. The higher the coverage of treatment, the lower the viral load in the population, and the lower the incidence of new infections. Incidence is very diffi cult to measure directly as...
OBJECTIVES This study was conducted to compare viral dynamics in blood and semen between subjects with antibody negative, acute HIV-1 infection and other subjects with later stages of infection. DESIGN A prospective cohort study was embedded within a cross-sectional study of HIV screening in a Lilongwe, Malawi STD clinic. METHODS Blood samples from HIV antibody negative or indeterminate vol...
CONTEXT Vitamin D is increasingly recognized as an important immunomodulator. Lower levels of 25-hydroxyvitamin D (25[OH]D) and 1,25-dihydroxyvitamin D (1,25[OH]2D) are observed in persons living with HIV. OBJECTIVE The purpose of this study was to evaluate the relationship of 25(OH)D, and 1,25(OH)2D to HIV viral load, and CD4+ T cells in HIV-infected adults. DESIGN This was a cross-section...
Objective: To evaluate the safety and tolerability of RAL therapy and the rapidity with which RAL decreases viral load in HIV-infected pregnant women. Methods: Women were considered for inclusion in the study if they were HIV-seropositive, ≥18 years of age, and received RAL during pregnancy. HIV viral load, CD4 count (absolute), pregnancy demographics, antiretroviral regimens, adverse events, l...
We evaluated the predictive value of baseline HIV-1 genotypic resistance mutations for failure of a nucleoside reverse transcriptase inhibitor (NRTI) containing therapy. The change in therapy of 88 HIV-1-infected patients was analyzed retrospectively, relating the genotypic resistance profile at baseline to the evolution of viral load and CD4+ T cell counts. Genotypic resistance at baseline and...
BACKGROUND There is concern that antiretroviral therapy (ART) use with only clinical monitoring for failure will result in high rates of transmission of virus with resistance to drugs currently in use. METHODS A stochastic simulation model of transmission of HIV, natural history and the effect of ART, was developed and used to predict the proportion of new infections with resistance according...
Patients with human immunodeficiency virus type 1 (HIV-1) who receive antiretroviral therapy (ART) often achieve increased survival and improved quality of life. In this respect, monotherapy with darunavir/ritonavir (mDRV/r) can be a useful treatment strategy. This prospective study analyses the effect of mDRV/r on sperm quality and viral load in a group of 28 patients who had previously been g...
