Poor adherence and the subsequent development of drug resistance is one reason why HIV treatment can fail. A drug-resistant HIV strain is one which is less susceptible to the effects of one or more anti-HIV drugs.

    Respected world agencies are downplaying initial reports of a new strain of HIV found in the Philippines. The Joint United Nations Programme on HIV/AIDS (UNAIDS) and the World Health Organization (WHO) have both released statements that soundly reject recent initial media reports that warned their readers of a new, untreatable strain of HIV that has been identified in certain areas.

  • ARV stock-outs kill more Ugandans

    “Of recent, HIV drug stock-out is adding a lot of misery to us as service providers in the ART clinics because we get very few drugs from National Medical Stores (NMS) which is not enough for our patients. We keep on begging for drugs from nearby health centres. When patients spend long time without taking drugs, they develop resistance,” Dr Peter Andrew Kalema said.

  • Reported PrEP 'Failure' Most Likely a Lack of Proper Testing and Adherence

    When is a pre-exposure prophylaxis (PrEP) failure actually a provider failure? And how do we tell the difference? This was a question that came up at CROI 2018 after a poster presentation titled "Seroconversion on PrEP: A Protocol for Untangling Adherence versus Resistance Failure" sparked conversations and debates about how you distinguish an example of tenofovir/emtricitabine (Truvada) failing to protect an individual from acquiring HIV, versus a provider whose negligence and failure to follow Centers for Disease Control and Prevention (CDC) protocol may have put his or her patient at grave risk.

  • AZT: The phoenix of HIV treatment

    During the last 30 years, over 15 million people have received AZT: an antiretroviral used to prevent HIV/AIDS. While it has now been replaced with other drugs in high income countries, it is still used widely in low-to-middle-income countries; this poses issues due to difficulties in detecting resistance to the drug and the side effects it carries. In this blog, author of a paper published in Infectious Disease of Poverty, Eric J. Arts, discusses his career long connection to AZT and the issues with AZT-based treatments in sub-Saharan Africa.

  • Immediate HIV Treatment Has Little Impact on Risk of Future Drug Resistance

    Starting antiretroviral therapy (ART) immediately rather waiting until a person's CD4 count falls below 500 cells/µL has almost no impact on the person's risk of developing antiretroviral resistance over the next seven years, according to a study published online in the journal AIDS. In this 51,000-person analysis, the impact of immediate ART on acquired drug resistance disappeared almost completely among people starting treatment in 2005 or later.

Community Consensus Statement on Access to HIV Treatment and its Use for Prevention

Together, we can make it happen

We can end HIV soon if people have equal access to HIV drugs as treatment and as PrEP, and have free choice over whether to take them.

Launched today, the Community Consensus Statement is a basic set of principles aimed at making sure that happens.

The Community Consensus Statement is a joint initiative of AVAC, EATG, MSMGF, GNP+, HIV i-Base, the International HIV/AIDS Alliance, ITPC and NAM/aidsmap
