Updated media summary: Prevalence of HIV drug resistance in PrEP rollout participants who acquire HIV, Abstract 2585 

The following is an updated summary of Abstract 2585, which is related to the prevalence of HIV drug resistance in PrEP rollout participants who acquire HIV. It was featured in the IAS 2021 official press conference and news release, and has been updated to include new data and information from the author. 

A study from the Global Evaluation of Microbicide Sensitivity (GEMS) project found very low rates of seroconversion among individuals participating in HIV pre-exposure prophylaxis (PrEP) rollout programmes in sub-Saharan Africa. In the small subset of individuals who acquired HIV despite being in a PrEP programme, 23% were found to have HIV with resistance mutations to the antiretroviral drugs used for PrEP. 

The project implemented drug resistance monitoring for PrEP users who were diagnosed with HIV during participation in oral TDF-based PrEP programmes in Eswatini, Kenya, South Africa and Zimbabwe. Of the estimated 104,000 PrEP users, 229 seroconversions were reported and 208 participants provided a sample for the study. Half of participants were 16-24 years of age and three-quarters were female. The majority were on PrEP from more than three months before becoming HIV positive. 

Of the 118 samples successfully genotyped, 44% had at least one HIV drug resistance mutation. Most of the resistance mutations were unrelated to PrEP use; that is, they had originated from antiretroviral therapy in the partner who transmitted HIV. Only one-fifth of the samples had mutations associated with the drugs used for PrEP, with the majority (23 of 27 cases) due to the emtricitabine/FTC mutation, M184I/V. There were only four cases of tenofovir-resistant HIV. Fortunately, recent studies have shown that HIV with the M184V/I mutations and/or tenofovir-associated mutations can be effectively treated with widely available combinations of antiretroviral drugs that are in the form of one pill taken daily. 

“Taking PrEP every day is very effective at preventing HIV,” Dr Urvi Parikh, Associate Professor of Medicine at the University of Pittsburgh and Co-Director of the GEMS study, said. “The number of reported infections on PrEP was very small compared to the number of PrEP users, which tells us that the benefit of PrEP in preventing HIV far outweighs the risk of drug resistance.” Continued monitoring for drug resistance with PrEP rollout will be important for the long-term success of both treatment and prevention programmes.

WHAT: From 30 million cases to zero: China creates a malaria-free future

WHEN: Friday 2 July 2021 9h00 – 10h30 CET Register here

Over the course of seven decades, China, the world’s most populous country, succeeded in driving down its malaria burden from 30 million cases per year in the 1940s to zero in 2017 – a notable achievement that has been maintained to this day.

What were the critical factors that underpinned this achievement? What strategies did China employ to keep malaria at bay along its shared borders with neighboring malariaaffected countries? How has the Government and its people managed to maintain zero malaria cases throughout the COVID-19 pandemic? And what lessons can other countries draw from this success story?

On 2 July, representatives from China’s National Health Commission and frontline workers will join malaria programme managers from other regions, WHO experts and global partners in a virtual forum to share reflections and perspectives on China’s malaria elimination journey.

Discussions will be in English with simultaneous interpretation provided in Chinese, French and Spanish. A detailed agenda will be shared in due course.
