People with HIV are living longer on the latest anti-retroviral therapy. This is something any infectious disease specialist knows from their own clinical experience – but it’s reassuring (I would even argue necessary) to have objective data to support experience. A study published in the latest issue of Lancet provides this objective data. (Lancet. 2008 Jul 26;372(9635):293-9.)
The press release from Bristol University, academic home of the lead author, says:
Professor Jonathan Sterne of Bristol University’s Department of Social Medicine and Professor Robert Hogg of British Columbia Centre for Excellence in HIV/AIDS and Simon Fraser University, Vancouver, Canada and colleagues from The Antiretroviral Therapy Cohort Collaboration (ART-CC) compared changes in mortality and life expectancy among HIV-positive individuals on cART.
This collaboration of 14 studies in Europe and North America analysed 18,587, 13,914, and 10,584 patients who started cART in 1996-99, 2000-02, and 2003-05 respectively.
A total of 2,056 patients died during the study period, with mortality decreasing from 16.3 deaths per 1000 person-years to in 1996-99 to 10.0 in 2003-05 – a drop of around 40 per cent.
Potential life years lost per 1000 person-years also decreased over the same time, from 366 to 189 — a fall of 48 per cent. Life expectancy increased from 36.1 years in 1996-99 to 49.4 years in 2003-05, an increase of more than 13 years.
