What is PrEP? (What and why?)

In the AMPrEP (Amsterdam PrEP) project, GGD Amsterdam (the local Public Health Service) is investigating the use of PrEP (Pre-Exposure Prophylaxus) for HIV prevention.

 

PrEP is a pill which contains HIV inhibitors which can prevent an HIV infection. The pill is meant for people who are not living with HIV, but who run a high risk of infection. PrEP is short for Pre-Exposure Prophylaxus. This means you take it before you are exposed to a pathogen. PrEP consists of one pill, Truvada. It contains two medications which are also used for HIV treatment: emtricitabine and tenofovir disoproxil. PrEP makes it more difficult for HIV to infect cells and to multiply. This considerably reduces the risk of an HIV infection.

Aim

The project aims to investigate the use of PrEP (Pre-Exposure Prophylaxus) for HIV prevention. The research focuses on how many homosexual men and transgender people want to use PrEP, whether they adhere to the therapy, the experiences of people using PrEP overall, and whether it affects condom use. It is the first time that PrEP is being investigated in the Netherlands and our project is the first to offer participants a choice: using PrEP on a daily basis or using PrEP according to a fixed schedule around sex. GGD Amsterdam will use the project results to advise on whether to adopt PrEP as a standard intervention for HIV prevention in the Netherlands.

From August 2015 through May 2018, PrEP is being provided to the study participants. After this, until 1 December 2018, the participants will visit the STD polyclinic twice more. During the project’s run, interim findings will be made known, and the final results will be published at the beginning of 2019.
