A community-based healthcare package combining testing and prevention tools, including pre-exposure prophylaxis (PrEP), immediate HIV treatment, management of hepatitis B virus, and sexual and reproductive health (SRH), targeting female sex workers (FSWs) in Côte d'Ivoire: the ANRS 12381 PRINCESSE project.

BACKGROUND: Pre-exposure prophylaxis (PrEP) is recommended by the WHO for HIV prevention among female sex workers (FSWs). A study conducted in 2016-2017 in Côte d'Ivoire showed that if PrEP is acceptable, FSWs also have many uncovered sexual health needs. Based on this evidence, the ANRS 12381 PRINCESSE project was developed in collaboration with a community-based organization. The main objective is to develop, document, and analyze a comprehensive sexual and reproductive healthcare package among FSWs in Côte d'Ivoire. METHODS: PRINCESSE is an open, single-arm interventional cohort of 500 FSWs in San Pedro (Côte d'Ivoire) and its surroundings. Recruitment started on November 26th, 2019 and is ongoing; the cohort is planned to last at least 30 months. The healthcare package (including HIV, hepatitis B, and sexually transmitted infection management, pregnancy screening, and contraception) is available both at mobile clinics organized for a quarterly follow-up (10 intervention sites, each site being visited every two weeks) and at a fixed clinic. Four waves of data collection were implemented: (i) clinical and safety data; (ii) socio-behavioral questionnaires; (iii) biological data; and (iv) in-depth interviews with female participants. Four additional waves of data collection are scheduled outside the cohort itself: (i) the medical and activity records of Aprosam for the PRINCESSE participants; (ii) the medical records of HIV+ FSW patients not participating in the PRINCESSE cohort, and routinely examined by Aprosam; (iii) in-depth interviews with key informants in the FSW community; and (iv) in-depth interviews with PRINCESSE follow-up actors. DISCUSSION: The PRINCESSE project is one of the first interventions offering HIV oral PrEP as part of a more global sexual healthcare package targeting both HIV- and HIV+ women. Second, STIs and viral hepatitis B care were offered to all participants, regardless of their willingness to use PrEP. Another innovation is the implementation of mobile clinics for chronic/quarterly care. In terms of research, PRINCESSE is a comprehensive, interdisciplinary project combining clinical, biological, epidemiological, and social specific objectives and outcomes to document the operational challenges of a multidisease program in real-life conditions. TRIAL REGISTRATION: The PRINCESSE project was registered on the Clinicaltrial.gov website ( NCT03985085 ) on June 13, 2019.

Incidence of HIV infection and associated factors among female sex workers in Côte d'Ivoire, results of the ANRS 12361 PrEP-CI study using recent infection assays.

BACKGROUND: This study aimed to estimate, using an HIV Recent Infection Testing Algorithm (RITA), the HIV incidence and its associated factors among female sex workers (FSW) in Côte d'Ivoire. METHODS: A cross-sectional study was conducted in 2016-2017 in Abidjan and San Pedro's region among FSW aged ≥ 18 years. In addition, a sociodemographic questionnaire, HIV screening was carried out by two rapid tests. In the event of a positive result, a dried blood spot sample was taken to determine, using a RITA adapted to the Ivorian context, if it was a recent HIV infection. RESULTS: A total of 1000 FSW were surveyed with a median age of 25 years (interquartile range: 21-29 years). 39 (3.9%) tested positive for HIV. The incidence of HIV was estimated to be 2.3 per 100 person-years, with higher incidence rates among those 24 years old or less (3.0% vs. 1.9%), non-Ivorian FSW (3.2% vs. 1.9%) and those with the lowest education level (4.6% in FSW who never went to school vs. 2.6%). The incidence seemed to be associated with the sex work practice conditions: higher incidence among FSW whose usual price was less than 3.50$ (4.3% vs.1.0%), FSW who had a larger number of clients on the last day of work (6.1% in those with 7 clients or more vs. 1.8%), FSW who reported not always using condoms with their clients (8.5% vs. 1.5%) and FSW who reported agreeing to sex without a condom in exchange for a large sum of money (10.1% vs. 1.2%). CONCLUSION: This study confirms that FSW remain highly exposed to HIV infection. Exposure to HIV is also clearly associated with certain sex-work factors and the material conditions of sex work. Efforts in the fight against HIV infection must be intensified to reduce new infections among FSW.
