  4. When to start treatment? 2002 1996 1998 2000 2002 2004 2006 2008 2010 2012 2014 • Eradication proved impossible as we began to realise that HIVremained hidden in “viral reservoirs”…control of the virus wasthe best we could hope for[1,2] • And concerns were soon raised about the emergence ofresistance if the virus was not fully suppressed in an individualwho was taking therapy for 30-50 years or more[3-5] • The existing drugs were not thought to be as potent anddurable[6] • There were also concerns about side effects that may occurwith a lifetime on long term medication[6] • In particular, there were concerns with the increasing numbersof people being affected by lipodystrophy (body fat changes) which could showthrough very quickly with some of the early drug regimes used[7-9] [1] Flexner C.

  5. When to start treatment? 1996 1998 2000 2002 2004 2006 2008 2010 2012 2014 • The goalposts have moved back and forth over the years since Time magazine named Dr. David Ho, Man of the Year on Dec. 30, 1996[1] • “Hit early hit hard,” was initially the American strategy[2] • Perhaps, according to this approach, the virus could be completely eradicated [1] Time Magazine, 30th December 1996 [2] Ho DD, Time to Hit HIV, Early and Hard.

  7. Delay Treatment Era:Reasons we were cautious 2005 1996 1998 2000 2002 2004 2006 2008 2010 2012 2014 • If we had perfect drugs with no cost issues, no side effects, no resistance concerns and no issues with adherence we might treat everyone from the day of diagnosis[1] • But early drugs were complex combinations – there were high pill counts, sometimes to be taken three times daily, so they could be difficult to adhere to[2,3] – and difficult to stomach!

  8. Delay Treatment Era:Reasons we were cautious 2005 1996 1998 2000 2002 2004 2006 2008 2010 2012 2014 • So we delayed starting treatment until the risk of HIV/AIDS complications became significant[1] • We put off taking drugs until the CD4 count went below 200 cells/mm3 or until the viral load went too high – above 100,000 copies/ml[2] • More evidence based guidelines were needed on when to start[1] [1] Expert opinion of author Brian West as well as the BEST Advisory Board and Review Committee; agreed on 24th September 2009 [2] European AIDS Clinical Society (EACS) European Guidelines for the Clinical Management and Treatment of HIV Infected Adults 2005 8

  9. The rationale started to change 2006 1996 1998 2000 2002 2004 2006 2008 2010 2012 2014 • Over time the drugs became easier to take and less toxic[1] • Living long term with HIV meant it wasn’t just about the ART[1] • We soon became concerned about other serious illnesses – more people were beginning to die of diseases not thought to be HIV-related than were dying of AIDS[2] • So what damage was untreated HIV doing to us?

  10. SMART: HIV-Related clinical events 2006 1996 1998 2000 2002 2004 2006 2008 2010 2012 2014 • Then SMART came along and surprised us[1] • The SMART study was designed to examine a strategy of limiting time on ART with the hope of reducing the rates of treatment associated complications[2] • 5,472 patients with a CD4 count of >350 were randomised to either stay on treatment* or take a treatment break[2] [1] HIV Positive!

  11. SMART: Non-HIV clinical events 2006 1996 1998 2000 2002 2004 2006 2008 2010 2012 2014 • The study showed the importance of other serious non-AIDS events such as heart attack and stroke among patients interrupting HIV treatment[1] • Significantly more (1.7 times more)* individuals in the treatment interruption arm developed major heart disease and stroke, kidney or liver disease than those who stayed on treatment[1] [1] The Strategies for Management of Antiretroviral Therapy (SMART) Study Group. N Engl J Med 2006;355:2283-2296 11

  13. The study on when to start ART 1996 1998 2000 2002 2004 2006 2008 2010 2012 2014 2015 • The best way to decide when to start is through a randomised trial – the START study did this[1] • People living with HIV and a CD4 over 500 were randomised to immediate or deferred treatment(CD4 count 350-500) • First results were expected in 2016 • The START DSMB stopped the randomised portion of the trial ahead of schedule in May 2015 • START found that people living with HIV have a considerably lower risk of developing AIDS or other serious illnesses if they start taking ART sooner, when their CD4 cell count is above 500 cells/mm3, instead of waiting until their CD4 cell count drops below 350 cells/mm3 [1] http://www.aidsmap.com/START-trial-provides-definitive-evidence-of-the-benefits-of-early-HIV-treatment/page/2986272/

ART and preventing HIV transmission 1996 1998 2000 2002 2004 2006 2008 2010 2012 2014 • European and national guidelines increasingly address the issue of the use of ART in preventing HIV transmission • .

  16. Conclusions 1996 1998 2000 2002 2004 2006 2008 2010 2012 2014 2009 • Now, European, WHO and US guidelines have reached a consensus[1] • That ART should be initiated in everyone living with HIV irrespective of CD4 cell count. 16 [1] WHO - http://www.who.int/hiv/pub/guidelines/earlyrelease-arv/en/ guidellines September 2015
