Life expectancy of 20-year-old patients starting treatment for HIV has increased by about a decade in the European Union and North America since the introduction of antiretroviral therapy in the mid-1990s, according to research published in The Lancet HIV. The authors, from the University of Bristol, proposed that their findings could reduce stigmatisation and help people with HIV infection gain employment and obtain medical insurance, as well as encouraging diagnosed patients to start treatment as soon as possible. Their projections indicate that the life expectancy of a typical 20-year-old patient who began treatment since 2008 and had a low viral load after a year of treatment may approach that of the general population (about 78 years). The study analysed data from 18 EU and North American studies for 88 504 people with HIV infection who started antiretroviral treatment between 1996 and 2010. It tracked how many people died during the first 3 years of their treatment, their cause of death, HIV viral load, immune cell (CD4) count and whether they were infected through injecting drugs. Fewer people who started treatment between 2008 and 2010 died during the first 3 years of treatment than those who started treatment between 1996 and 2007. The number of deaths during treatment directly attributable to AIDS declined between 1996 and 2010, probably the result of newer drugs being more effective in restoring immune function. Measures of HIV also improved, with the average CD4 cell count after a year of treatment increasing from 370 cells per microlitre of blood in 1996–1999 to 430 cells per microlitre in 2008–2010, while the proportion of people with a low HIV viral load increased from 71% to 93%. Between 1996 and 2013, the life expectancy of 20-year-old patients treated for HIV infection increased by 9 years for women and 10 years for men in the EU and North America. Projections based on death rates in the second and third year of treatment for Europeans and North Americans estimated that 20-year-old men and women starting therapy between 2008 and 2010 who survived the first year of treatment would live to 73 and 76 years respectively.
