Breakthrough research confirms HIV treatment prevents transmission

A ground-breaking study released yesterday by the US National Institutes of Health found that HIV-positive people receiving anti-retroviral treatment are 96 percent less likely to transmit HIV to their partners. This landmark study was carried out in nine different countries around the world and could change the way HIV patients are treated in the future.

The study observed over 1,700 couples of whom one partner was living with HIV with a CD4 count (white blood cells) between 350 and 550 and were not yet eligible for HIV treatment, according to WHO guidelines. The couples were divided into two groups. In the first group, treatment for the HIV positive individuals was delayed until there was evidence of a weakened immune system. In the second group, HIV positive individuals were started on treatment right away.

Those individuals started on treatment immediately decreased their risk of transmitting the virus to their uninfected partner by 96 percent. The findings were so overwhelming that the study was cut short 3-4 years ahead of schedule.

Dr Margaret Chan, Director-General of the WHO, said:

“This is a crucial development, because we know that sexual transmission accounts for about 80 per cent of all new infections. The findings from this study will further strengthen and support the new guidance that WHO is releasing in July to help people living with HIV protect their partners.”

These findings have significant implications for mobilising additional resources to fund HIV treatment around the world to provide HIV treatment to all those who need it. Furthermore, an increase in access to HIV testing is needed as only an estimated half of the 33 million people living with HIV are aware of their status. Earlier diagnoses of HIV would result in more people starting treatment earlier, thus reducing the chance of transmission to others.

Free Trade Agreement could threaten medicines for world’s poor

India has been described at the ‘pharmacy of the developing world’, providing a high proportion of the cheap drugs used by people living in poor countries.  But this could now be under threat as the European Union negotiates a Free Trade Agreement (FTA) with India.  Campaigners from Medecins Sans Frontieres (MSF) and other NGOs are now calling for changes to be made to the agreement to ensure that life-saving drugs will still be available to many of the world’s poor.

Concern centre around ‘data exclusivity’, which would prevent drugs companies relying on existing clinical trial data to produce and sell new drugs.  India has in the past given space for companies to produce cheaper generic medicines, by not fully implementing intellectual property rules.   Since 2005 India has started to change these rules, but only for truly innovative medicines, meaning that existing drugs can still be manufactured and sold cheaply.   But this compromise could be under threat if the EU-India FTA is introduced in its current form.

These changes could severely reduce access to medicines, particularly lifesaving HIV drugs, for the poorest people.  Competition between generic manufacturers in India has forced prices down.  AIDS treatment has dropped from $10,000 per patient per year in 2000 to under $70 today.  To give a sense of the scale of what’s at stake, MSF say that 80% of the HIV/AIDS medicines that they use come from generic manufacturers based in India.

MSF have launched a catchy-named campaign – ‘Europe! Hands off our Medicine’ – to try to ensure the EU and India find a solution which will protect access for the world’s poor to cheap medicines.   More details about this can be found on the MSF website at http://www.msf.org.uk/handsoff.aspx.  Key negotiations are taking place in March and April.  NGOs and campaigners now need to scrutinise and campaign to make sure this Free-Trade Agreement contains the necessary measures to protect medicines for the poor.
