The Latest Treatment Action Campaign (TAC) Briefing - Antiretrovirals and Prevention

via the Treatment Action Campaign (TAC), by Catherine Tomlinson and Nathan Geffen

Exciting new evidence has demonstrated the potential of antiretroviral medicines (ARVs) to prevent HIV from being sexually transmitted. This TAC briefing explains the evidence and then discusses policy implications.

Our recommendations

1.The WHO must release its guidelines on serodiscordant couples.
2.People living with HIV should be offered highly active antiretroviral treatment (ART) when their CD4 counts fall below 350 cell/mm3, or if they have an AIDS illness or TB.
3.HIV-positive people in serodiscordant couples should be offered ART irrespective of their CD4 count.
4.For serodiscordant couples trying to conceive, both partners should be offered ARVs until conception is confirmed, after which the HIV-positive partner should continue on ART.
5.Pre-exposure prophylaxis (PrEP) should be made available to sex workers.
6.In other cases, pre-exposure prophylaxis should be made available to HIV-negative people who request it or who will --in the opinion of their nurse or doctor-- likely benefit from it.
7.The rollout of ARVs for prevention must not divert funding away from treatment programmes. Achieving universal access for people with HIV must remain the priority for governments, policy makers and funders.
8.Effective prevention interventions such as voluntary medical male circumcision and ensuring availability of male and female condoms continue to be critically important.

Building the momentum to prevent HIV in MSM

Via The Lancet, by Thomas J Coates.

Larry Kramer, on accepting the Tony Award last month from the Theatre Guild-American Theatrical Society for The Normal Heart as Best Revival of a Play said: “To gay people everywhere, whom I love so dearly…we are a very special people, an exceptional people, and…our day will come.” My day came in 1982 when I secured an Assistant Professorship in the Department of Medicine at the University of California, San Francisco. I set about establishing a behavioural medicine clinic fully integrated into general medicine practices, researching chronic disease prevention, and teaching interns and residents about psychological issues. One guest speaker, a social worker, led a discussion with the residents about the special medical needs of gay men. He was dead a month later from what later became known as AIDS.

The “special and exceptional people” cited by Kramer had lived through the 1970s and fought for human rights in the USA. That was followed in 1981 with the scourge of AIDS that could have knocked the wind out of the gay community. Instead, the community rallied and used its skills and talents to advocate for resources to develop community-based systems of care and prevention, and to ensure that human rights were not trampled.

Unleashing that energy and skill to build a global movement to improve HIV prevention and care services for men who have sex with men (MSM) is long overdue. Momentum is building and Chris Beyrer and co-authors make an important contribution. The Global HIV Epidemics among Men Who Have Sex with Men documents the extent of the HIV epidemic and outlines what needs to happen to ensure that everything possible is being done to prevent and treat HIV infection in MSM worldwide.

This volume documents the need in terms of the numbers, but also addresses the scenarios in which HIV epidemics among MSM exist in low-income and middle-income countries. The first scenario they describe, characterising the HIV epidemic in most of Latin America, is one in which MSM are the predominant exposure mode for HIV infection in the population. In these countries MSM are ten to over 100 times more likely to have HIV than the general population. By contrast, eastern Europe and central Asia have the highest rates of HIV among injection drug users (IDUs), but MSM are still several times more likely to have HIV than the general population. A different scenario is found in sub-Saharan Africa where HIV is widespread among heterosexuals, but even in these contexts MSM can have two to 20 times higher prevalence of HIV than the general population estimates. South, southeast, and northeast Asia are characterised by epidemics that have equal contributions from MSM, IDUs, and heterosexuals, although MSM are still at least ten times more likely to have HIV than the general population.

The needs come not only from the numbers. Beyrer and his co-authors document well the lack of prevention technologies focused on male-to-male transmission. They note that much effort has been expended on encouraging voluntary HIV counselling, testing, and behavioural interventions to decrease rates of unprotected anal intercourse by encouraging less risky sexual behaviours. Although important, such strategies are probably insufficient to produce immediate or lasting change in HIV transmission. Male circumcision may be effective for reducing acquisition of HIV through anal intercourse but we will never know for sure because of the challenges of conducting a trial to prove efficacy. Antiretroviral-based prophylactic approaches provide the best opportunity for managing HIV among MSM. In the wake of the IPREX, CAPRISA 004, and HPTN 052 trials, it is now time to accelerate efforts to determine if similar benefits can be obtained with rectal use of these or similar compounds. In some countries, like Peru where the epidemic is concentrated in MSM, providing universal access to care with MSM-sensitive services could actually change the overall trajectory of disease spread.

Treatment as Prevention – The Tough Road Ahead


The sixth International AIDS Society Conference on HIV Pathogenesis, Treatment and Prevention started optimistically as the hype surrounding the use of antiretroviral treatment to prevent HIV infection gained momentum. But the focus of much discussion in Rome from 17-20 July will undoubtedly be on how to transform the recent promising research findings into workable policy.

The most significant of these is the HPTN052 randomized control trial, which found that earlier antiretroviral treatment can reduce the risk of heterosexual HIV transmission by as much as 96 percent; other studies have proven the efficacy of ARVs for prevention in HIV-negative people.

"We need to ensure that the advances we are making in research – such as the now proven concept of antiretroviral treatment as a means of HIV prevention – are translated into action for people in developing countries," said IAS local co-chair Stefano Vella, research director at Italy’s Istituto Superiore di Sanità, at the official opening of the conference.

But translating the research into action will require money, and if recent trends are any indication, that will be difficult, and there is much scepticism about the ability to significantly increase the numbers on treatment with such limited funds.

Donor pressure
"We need to keep up the pressure on donors... Donors are used to seeing costs rising year after year, but now we can show them a light at the end of the tunnel... We can show them that investing today will lead to lower costs tomorrow," Brenda Waning, coordinator of market dynamics with the health financing mechanism, UNITAID, said. "We also need to learn how to do more with limited resources."

Treatment as prevention will mean putting significantly more people on treatment earlier; at present, 15 million people are estimated to need ARVs – only 6.6 million have access to them.

"Treatment as prevention is possible, it is feasible, but we must not fool ourselves into thinking it's going to be easy," said Paul de Lay, deputy executive director of UNAIDS. "We put an additional 1.4 million new people on treatment in 2010 – if we maintain that momentum we will not achieve the goal of 15 million on treatment by 2015.

"We need to get to US$22 to $24 billion a year from the $15 billion a year we are currently spending; we need African governments to abide by the Abuja Declaration commitment to spend 15 percent of national budgets on health and we need donors to meet their commitments," he added.

"If we can convince donors that we can stop the epidemic within a finite amount of time, the money will be found," said Brian Williams, an epidemiologist with the UN World Health Organization (WHO).

Scaling-up HIV testing
Key to putting more people on treatment earlier will be finding those who need it; according to De Lay, most countries with hyper-endemic epidemics are testing just 4 percent of their populations.
