CD4 cell counts help in assessment of AIDS or death risk in HIV-infected adults on cART

Peer-Reviewed Publication

PLOS

Using data from the Collaboration of Observational HIV Epidemiological Research in Europe (COHERE), Jim Young and colleagues from The Opportunistic Infections Project Team of COHERE show in this week's PLoS Medicine that in successfully treated patients, the risk of a new AIDS event or death follows a CD4 cell count gradient in patients with viral suppression. An increase in CD4 cell count provides the greatest benefit for patients with a CD4 cell count below 200 cells/µL but still provides some benefit for those with a CD4 cell count above 500 cells/µL, report the authors.

Funding: The COHERE study group has received generic funding from: Agence Nationale de Recherches sur le SIDA et les Hépatites Virales (ANRS), France; HIV Monitoring Foundation, The Netherlands; and the Augustinus Foundation, Denmark COHERE, which receives funding from the European Union Seventh Framework Programme (FP7/2007-2013) under EuroCoord grant agreement nu 260694. A list of the funders of the participating cohorts can be found on the Regional Coordinating Centre websites at http://www.cphiv.dk/COHERE/tabid/295/Default.aspx and http://etudes.isped.u-bordeaux2.fr/cohere. This project was funded by unrestricted grants from the Emile Dreyfuss Foundation, Basel, Switzerland and the Stiftung für Infektiologie Beider Basel, Basel, Switzerland. Jim Young and Heiner C. Bucher are supported by Santé suisse and the Gottfried and Julia-Bangerter-Rhyner-Foundation. These funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.
