TL;DR: The purpose of this report is to update researchers on the progress of the WIHS and to provide information on WIHS resources, the methods by which they were obtained, and background for any new potential researchers interested in conducting collaborative research through shared use of these resources.
Journal ArticleDOI

TL;DR: It is estimated that cART halved the average mortality rate in HIV-infected individuals and was greater in those with worse prognosis at the start of follow-up.
Journal ArticleDOI
Effect of transmitted drug resistance on virological and immunological response to initial combination antiretroviral therapy for HIV (EuroCoord-CHAIN joint project): a European multicohort study
Linda Wittkop,Huldrych F. Günthard,Frank de Wolf,David Dunn,Alessandro Cozzi-Lepri,Alessandro Cozzi-Lepri,Andrea De Luca,Andrea De Luca,Claudia Kücherer,Niels Obel,Viktor von Wyl,Bernard Masquelier,Christoph Stephan,Carlo Torti,Andrea Antinori,Federico García,Ali Judd,Kholoud Porter,Rodolphe Thiébaut,Hannah Castro,Ard van Sighem,Céline Colin,Jesper Kjaer,Jens D Lundgren,Roger Paredes,Anton Pozniak,Bonaventura Clotet,Andrew N.

TL;DR: Findings confirm present treatment guidelines for HIV, which state that the initial treatment choice should be based on resistance testing in treatment-naive patients, that the effect of TDR on outcome in the first year of cART is confirmed.
Journal ArticleDOI
Virological monitoring and resistance to first-line highly active antiretroviral therapy in adults infected with HIV-1 treated under WHO guidelines: a systematic review and meta-analysis.
Ravindra K. Gupta,Andrew Hill,Anthony W. Sawyer,Alessandro Cozzi-Lepri,Viktor von Wyl,Sabine Yerly,Viviane D. Lima,Huldrych F. Günthard,Charles F. Gilks,Deenan Pillay +9 more
TL;DR: The need for cheap point-of-care viral-load tests to identify early viral failures and limit the emergence of resistance is highlighted, with genotypic resistance at 48 weeks to lamivudine, nucleoside reverse transcriptase inhibitors (thymidine analogue mutations), and non-nucleoside Reverse Transcriptase inhibitors appears substantially higher in less frequently monitored patients.
Journal ArticleDOI
When to initiate combined antiretroviral therapy to reduce mortality and AIDS-defining illness in HIV-infected persons in developed countries: an observational study
Lauren E. Cain,Roger Logan,James M. Robins,Jonathan A C Sterne,Caroline A. Sabin,Loveleen Bansi,Amy C. Justice,Joseph L. Goulet,Ard van Sighem,Frank de Wolf,Heiner C.

TL;DR: Initiation of cART at a threshold CD4 count of 0.500 × 10(9) cells/L increases AIDS-free survival, and mortality did not vary substantially with the use of CD4 thresholds between 0.300 and 0.200, while Residual confounding may exist.
