About

By a prospective single center cohort study in the Sexual Assault Care Center (SACC) of the CHU (Centre Hospitalier universitaire) Saint Pierre in Brussels, we would like to :

to evaluate the prevalence of HPV infections in the population of women over 15 years old admitted for rape
to determine the prevalence of HPV and the clearance in HPV-vaccinated and unvaccinated patients

Full description

The investigators will conduct a prospective single center cohort study in the SACC of the CHU Saint Pierre in Brussels.

Population:

the investigators will include all women over 15 years admitted to the SACC of Brussels between 5/02/2024 and 05/02/2024 for rape (vaginal and/or oral and/or anal penetration) after signing the consent.

PCR (polymerase chain reaction) smears for HPV testing will be performed after obtaining consent from the victims. These smears will be performed at the oral, vaginal and anal site. The smears will be taken either by the patient or by the legal nurse, according to the victim's wishes. Ideally, 3 smears should be taken : oral, vaginal and anal.

It will be carried out at the same time as all other sexual transmitted deseases tests and should therefore not be perceived as more invasive or time-consuming.

These smears will be performed two times: at the first visit of the patients to the SACC and after 12 at 18 months.

Appointment reminders will be sent by phone contact.

The test used is a swab analyzed by PCR via the AML laboratory. They confirmed that this is the most sensitive method for detecting HPV in vaginal and anal areas, and probably also in oral areas.

The HPVs obtained via PCR are: 16 18 45 33 58 31 52 35 59 39 51 56 68 67 53 66 6 and 11. Results will therefore be classified as low-risk, high-risk or HPV-negative.

Patients will be notified if a high-risk HPV test is detected, and treatment will be offered depending on the type of follow-up required according to the international recommendations.

Outcomes:

Define high-risk HPV carriage in the SACC population.
Define the proportion of SACC patients vaccinated for HPV.

Secondary objectives:

To characterize HPV subtypes, according to the type of assault and infected sites (vaginal-cervical, anal, oral).
To determine the prevalence of HPV and the clearance in HPV-vaccinated and unvaccinated patients (itself assessed by the presence of one type of HPV in the first smear and its absence in the followed smears).
