About this study

This is a cohort, non-health product, non-interventional biomedical research, multi-centric, to determine the seroprevalence of mpox infection in the population of people living with HIV and in PrEP users in Ile-de-France and in the province.

Read the detailed description

The target population is the population of people living with HIV (PLHIV) (n=18,500) and PrEP users (n=4930) followed up in Parisian infectious and tropical diseases departments (SMIT) of the Pitié-Salpêtrière, Tenon, Saint-Antoine, Bichat, Saint-Louis, Necker hospitals, the University Department of Infectious and Traveller Diseases of Hôpital Dron (Tourcoing), the 190 health center, and the Maison de santé du Chemin vert (Paris).

The principal objective is to determine the seroprevalence of Monkeypox infection in the population of PLHIV and PrEP users followed in the infectious and tropical disease departments in 9 centers.

In addition to the primary objective, there exist the following secondary objectives:

  • To assess the level of anti-Mpox antibodies in PLHIV and PrEP users
  • To assess the level of anti-Mpox antibodies in PLHIV and PrEP users with a previous confirmed diagnosis of Mpox or if they have been recently vaccinated
  • Assess antibody levels in PLHIV in relation to CD4 cell count and HIV viral load
  • Study antibody kinetics and persistence over time (D0 (between November 1, 2021 and April 30, 2022), M6, M12)
  • Study the Mpox seroconversion rate over time
  • Determine the neutralizing activity of anti-Mpox antibodies in individuals with positive anti-Mpox ELISA serology.
  • Describe the natural history of the disease, the different forms of the disease, their clinical characterization
  • Describe sexual behavior and the impact of this health crisis on different aspects of their lives using a self-administered questionnaire
  • To determine the prevalence of asymptomatic infections
  • Proportion of participants with positive Mpox serology without PCR confirmed diagnosis
  • History of childhood or recent smallpox vaccination

During the patient's follow-up consultation, after information and in the absence of an expression of no objection, inclusion will consist of recovering a blood sample taken between November 2021 and April 2022 during the HIV infection assessment or PrEP follow-up (no additional sample) and possibly the blood sample taken at M6 and/or M12 if this follow-up consultation has already taken place.

An online self-questionnaire will also be proposed to the patient (male only). It will be constructed from questions already validated in other surveys (Rapport au Sexe, Prévenir, Parcours).

A check on the appearance or persistence of antibodies will be carried out at M6 +/- 8 weeks and/or M12 +/- 8 weeks on tube bottoms of samples always taken as part of the HIV infection assessment or PrEP follow-up.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mpox serology

    The primary endpoint will be to determine the presence or not of anti-Mpox antibodies in the population of PLHIV or PrEP users

    Measured: 12 months

Secondary outcomes (10)
  1. Anti-Mpox antibodies

    To determine the presence or not of anti-Mpox antibodies by ELISA in PLWHIV and PrEP users with a previous confirmed diagnosis of Mpox or with a recent vaccination

    Measured: 12 months

  2. Antibody level in PLWHIV

    Comparison of Mpox serology with CD4 count and viral load of PLHIV

    Measured: 12 months

  3. Antibody kinetics

    Comparison of Mpox antibody levels between D0, M6 and M12

    Measured: 12 months

  4. Mpox seroconversion

    Comparison of anti-Mpox serology results between D0, M6 and M12

    Measured: 12 months

  5. Neutralizing activity

    Observation of the number of serum-neutralization test results for all Mpox-positive samples

    Measured: 12 months

  6. Natural history of Mpox

    Collect information on date of seropositivity, date of onset of symptoms, types of symptoms, clinical features of infection.

    Measured: 12 months

  7. Asymptomatic infections

    Comparison of the proportion of asymptomatic vs. symptomatic in HIV-positive patients.

    Measured: 12 months

  8. Mpox serology and PCR

    Comparison of the proportion of asymptomatic, the proportion with symptoms without PCR confirmation, proportion vaccinated in the past or recently

    Measured: 12 months

  9. Childhood or recent smallpox vaccination

    Comparison of proportion with PCR-confirmed Mpox, proportion previously or recently vaccinated.

    Measured: 12 months

  10. Sexual behavior

    To count and collection of sexual behavior and impact of health crisis among PLWHIV and PrEP users via self-questionnaire

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

An observational study of Monkey Pox and HIV Infections, run by ANRS, Emerging Infectious Diseases.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 28 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Simon AMADOR PAZ (01 53 94 80 78, simon.amador-paz@anrs.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mpox serology (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Jun 2023.
