About this study

The objective of the study is to identify the pathophysiological mechanisms responsible for the induction and maintenance of negative serologies by EIA tests in HIV-infected children treated early with HAART in the ANRS 12225-Pediacam III cohort in Cameroon

The hypothesis of better control of HIV infection through interactions between immunological, viral, and genetic factors was made to build the following objectives:

  • Immunological aspect: lack of humoral response or immune activation
  • Virological aspect: Reduced HIV reservoir size
  • Determine the HLA phenotype in the different groups of children included and the KIR genotypes.
Read the detailed description

There will be two phases of the study :

  • A retrospective phase: case-control study The analyzed data are those collected previously or measured from the already available bio bank, within the framework of the Pediacam III cohort during the primary infection phase before the initiation of HAART, at 6 months after the end of the first series of EPI vaccines, and at 2 years.
  • A prospective phase: cross-sectional study Based on an ad hoc bio bank created for parameters we couldn't measure on the existing bio bank

What is being measured

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

  1. Level of pro-inflammatory and anti-inflammatory cytokines, chimiokines in the plasma

    Measure of sCD14 (µg/ml). Levels of these biomarkers will be compared across all groups.

    Measured: 18 months

  2. Level of pro-inflammatory and anti-inflammatory cytokines, chimiokines in the plasma

    Measure of BAFF using luminex or commercially available ELISA quantification kits. Levels of these biomarkers will be compared across all groups.

    Measured: 18 months

  3. Level of pro-inflammatory and anti-inflammatory cytokines, chimiokines in the plasma

    Measure of CXCL13 using luminex or commercially available ELISA quantification kits. Levels of these biomarkers will be compared across all groups.

    Measured: 18 months

  4. Level of pro-inflammatory and anti-inflammatory cytokines, chimiokines in the plasma

    Measure of TNF-α (pg/ml). Levels of these biomarkers will be compared across all groups.

    Measured: 18 months

  5. Level of pro-inflammatory and anti-inflammatory cytokines, chimiokines in the plasma

    Measure of IL-10 (pg/ml). Levels of these biomarkers will be compared across all groups.

    Measured: 18 months

  6. Level of pro-inflammatory and anti-inflammatory cytokines, chimiokines in the plasma

    Measure of IP-10 (pg/ml). Levels of these biomarkers will be compared across all groups.

    Measured: 18 months

  7. Level of pro-inflammatory and anti-inflammatory cytokines, chimiokines in the plasma

    Measure of TRAIL (ng/ml). Levels of these biomarkers will be compared across all groups

    Measured: 18 months

Secondary outcomes (6)
  1. - Humoral response to vaccines against tetanus, pertussis, and viral hepatitis B

    Serum concentrations of human IgG antibodies against tetanus-toxoid, pertussis, and viral hepatitis B will be measured using commercially available ELISA quantification kits and results will be given as IU/mL

    Measured: 18 months

  2. - Functional and phenotypic characterization of B and T lymphocytes

    Level (cells/μL or percentage) of T and B-cell lymphocytes subpopulations will be assess in blood using flow cytometry. Functional characterization of T and B lymphocytes will be done by cell culture following by cytokine production titration

    Measured: 18 months

  3. - Size of the HIV reservoir

    Measure total (copies/million PBMC), integrated (copies/million PBMC), unintegrated (copies/million PBMC) HIV DNA level in Peripheral Blood Mononuclear Cells (PBMC)

    Measured: 18 months

  4. - Residual viremia in perinatally HIV-infected adolescent

    Any detectable HIV-RNA below 50 copies/mL

    Measured: 18 months

  5. - Level of HIV plasma p24

    Measure plasma level of HIV p24 antigen (fg/ml) using ultrasentsitive technique called Simoa (Single molecule array)

    Measured: 18 months

  6. - HLA phenotype and the KIR genotypes

    HLA-B (27 et 57), HLA-B35 ou 53, HLA-C16:01+KIR2DL3+

    Measured: 18 months

Questions about this trial

What is this clinical trial studying?

A study testing Blood sampling in people with HIV Infections, run by ANRS, Emerging Infectious Diseases at 3 sites in Cameroon.

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 11 inclusion and 2 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 30 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Cameroon. Whether a site is taking part right now should be confirmed with that site. See every site.

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 Mathurin C Tejiokem, Doctor (00237222231803, tejiokem@pasteur-yaounde.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Level of pro-inflammatory and anti-inflammatory cytokines, chimiokines in the plasma (time frame: 18 months). The study lists 7 primary outcomes in all. 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 30 Jan 2025.
