UNAIDS has launched a simpler, more cost-effective approach to HIV treatment, aimed at simultaneously achieving two holy grails of the AIDS response: drastic reductions in AIDS-related deaths and new HIV infections.
The approach, dubbed "Treatment 2.0", aims to drastically scale up testing and treatment using current best practices and future innovations in antiretroviral (ARV) drugs and diagnostics. The prevention benefits of extending treatment to all those in need of it are based on mounting evidence that people on ARV treatment are much less likely to transmit the virus.
UNAIDS estimates that successful implementation of Treatment 2.0 could avert 10 million deaths by 2025, and reduce new infections by one-third.
A report on the new strategy has been released ahead of the International AIDS Conference, starting on 18 July in Vienna, where one of the hot topics will be why most countries will fail to meet the goals of universal access to HIV prevention, treatment and care by the December 2010 deadline.
Worrying indications that international financial support for the AIDS response is flagging will also be debated, but UNAIDS director Michel Sidibe is pitching the Treatment 2.0 approach as offering a potential solution to both concerns.
"For countries to reach their universal access targets and commitments, we must reshape the AIDS response," he said in a statement. "Through innovation we can bring down costs, so investments can reach more people."
Treatment 2.0 calls for the creation of "better" HIV drugs that would be less toxic, combine multiple ARVs into one pill, and be more tolerant of treatment interruptions, as well as quicker and cheaper diagnostic tools.
The current generation of ARVs have far fewer side effects than those of a decade ago, and some are available in fixed-dose combinations, but poor adherence quickly leads to the development of drug resistance and the need to switch to more expensive second-line medicines.
Second-line ARVs also incur a number of non-drug related costs, like laboratory monitoring and clinic visits, which are often enough to push treatment out of reach, but Treatment 2.0 urges all involved in fighting HIV/AIDS to "Stop cost being an obstacle".
Bernhard Schwartlander, Director of the Evidence, Strategy and Results Department at UNAIDS, told IRIN/PlusNews that short-term investments in developing and rolling out better ARVs could radically reduce non-drug related costs in the mid- and long-term.
A smart investment
Starting patients on treatment earlier is integral to the successful implementation of Treatment 2.0, and is in line with the latest guidelines from the World Health Organization.
Earlier treatment would require an initial increase in funding, but UNAIDS argues that the reduced need for hospitalization and treatment of opportunistic illnesses, as well as the potential to avert countless new infections, would eventually save money.

|Treatment as prevention|
|Stop cost being an obstacle|
|Improve uptake of HIV testing and linkage to care|
|Strengthen community mobilization|
"We are living in a very resource-constrained situation," said Schwartlander, admitting that it would be difficult to convince donors and governments to increase AIDS funding in the current economic climate. "But what we see is that thinking is more and more shifting to seeing treatment as a very smart investment."
Treatment 2.0 also incorporates various strategies for simplifying and improving HIV treatment that already have a proven track record, including the use of local, community-based organizations to deliver HIV services to hard-to-reach but high-risk populations, such as injecting drug users and sex workers.
Organizations like The AIDS Support Organization (TASO) in Uganda, and the Treatment Action Campaign (TAC) in South Africa, are cited as examples of the successful use of community-based approaches to mobilize people infected and affected by HIV to become advocates, educators and service providers.
UNAIDS consulted extensively in drafting Treatment 2.0 and Schwartlander is optimistic that its positive, can-do approach will motivate the various sectors of the AIDS community that have tended to operate "in silos and sporadically" to work together to overcome the many obstacles to its implementation.
"So far the response has been very positive," he said. "It may be a way to re-inspire the major donors and the countries themselves."

Right now, we’re working with contributors on the ground in Ukraine and in neighbouring countries to tell the stories of people enduring and responding to a rapidly evolving humanitarian crisis.
We’re documenting the threats to humanitarian response in the country and providing a platform for those bearing the brunt of the invasion. Our goal is to bring you the truth at a time when disinformation is rampant.
But while much of the world’s focus may be on Ukraine, we are continuing our reporting on myriad other humanitarian disasters – from Haiti to the Sahel to Afghanistan to Myanmar. We’ve been covering humanitarian crises for more than 25 years, and our journalism has always been free, accessible for all, and – most importantly – balanced.
You can support our journalism from just $5 a month, and every contribution will go towards our mission.
