ANRS 12406 EvvA Study

Study Overview
=================
Brief Summary
-----------------
ANRS 12406 EvvA is an observational, longitudinal and monocentric study evaluating the virological success rate in HIV-infected adolescents on antiretroviral therapy in Cameroon. The main objective of the study is to estimate the rate of virological suppression among adolescents on antiretroviral therapy for more than 6 months in Cameroon

Detailed Description
-----------------
At the end of 2017, HIV-AIDS affects more than 36 million people worldwide, more than three-quarters of whom live in sub-Saharan Africa, and a quarter of the infections are among young people and adolescents. Every hour, 4 adolescents (aged 15-19) are newly infected with HIV in the world, and 3 of them are adolescents. Three infections occur in sub-Saharan Africa, and for five adolescents living with HIV, there are seven girls (aged 10 to 19) in the same situation. This gender disparity increases when adolescents reach adulthood. This group of the population may well deserve the term key and vulnerable population. In the era of international commitment to end the AIDS epidemic by 2030, especially to stop new infections, it is essential not to neglect part of the epidemic because it would effectively represent a reservoir for maintaining the epidemic and make these eradication goals impracticable. Data on virological success among adolescents on antiretroviral treatment are generally scarce and this is much more striking in Central Africa. Also, information on the frequency of emergence of resistant viruses and the consequences for the effectiveness of available treatments is rare. However, in the absence of such data, it is difficult, if not impossible, to take the right decisions to improve the care and monitoring of adolescents. In addition, the few available data indicate high virological failure rates and high frequencies of drug resistance, which may indicate a need to further investigate virological failure events in this population. This study will be conducted in Cameroon among 289 adolescents during 9 months, where access to biological monitoring is a major challenge, especially with low access to viral load testing. The results of this project will inform on the current state of success of ARV treatments in this population. Moreover, the other goal of this study is to conclude on the need to conduct a larger study at the national or regional level according to the results obtained
