About this study

Official title: Operational Evaluation of the Introduction of "Point Of Care" (POC) to Optimise Post-natal Prophylaxis of HIV-exposed Newborns According to the Risk of Maternal to Child Transmission (MTCT) Assessed by Measuring Maternal Viral Load at Delivery in Conakry, Guinea

The main objective is to evaluate the operationality of introducing the measurement of viral load in HIV-1 infected mothers at delivery by POC to optimise post-natal prophylaxis and neonatal diagnosis of children according to the estimated risk of MTCT (high risk: HIV viral load (VL) at delivery ≥ 1000 copies/mL, low risk: VL at delivery < 1000 copies/mL) in Conakry, Guinea.

Read the detailed description

Intervention:

All women screened for HIV-1 infection in the delivery room, whether or not the infection was previously known, whether or not they are treated, will be eligible to participate in this study and will be offered inclusion in the study.

The women will benefit from a viral load measurement by POC (Cepheid GenXpert HIV-1 viral load) at the time of delivery.

Newborns will benefit :

  1. the provision of antiretroviral (ARV) preventive treatment differentiated according to their risk of infection in accordance with national recommendations:
  • High risk (maternal VL ≥1000 cp/ml): zidovudine (AZT)/ nevirapine (NVP) for 12 weeks.
  • Low risk (maternal VL <1000 cp/ml): NVP for 6 weeks.
  1. early and regular virological screening for HIV by qualitative POC (Cepheid GenXpert HIV-1 qual) from birth (for high-risk newborns) at 6 weeks, at 9 months and at any time in the event of clinical manifestations suggestive of HIV infection.
  2. In the event of a positive HIV test, the child will initiate immediate antiretroviral treatment combining zidovudine (AZT)/ lamivudine (3TC)/ Lopinavir-retonivir (LPV/r) and a confirmatory test will be done by POC (Cepheid GenXpert HIV-1 viral load) according to World Health Organisation (WHO) and national recommendations.
  3. support from the project team and peers, volunteers from the association Fédération Espoir Guinée (FEG), to improve retention in care and compliance of mother and child, promotion of exclusive breastfeeding for 6 months and family nutritional support, Cotrimoxazole (CTX) prophylaxis and the Expanded Programme on Immunization will be provided by the national programme.

  1. Evaluate the operationally of introducing the measurement of viral load in HIV-1 infected mothers at delivery by POC

    Proportion of newborns having received antiretroviral prophylaxis within 48 hours after delivery adapted to the "real" risk of MTCT, defined by measuring the maternal viral load by POC at delivery.

    Measured: Day 0 to day 2

Secondary outcomes (25)
  1. To evaluate the intrinsic diagnostic performance of viral load measurement by POC Xpert HIV-1 in comparison with the evaluation of the level of risk by maternal interrogation alone.

    Sensitivity and specificity of the risk level assessment by the interrogation data in comparison with viral load measurement as a reference method.

    Defining the level of risk through interrogation :

    • High risk: newborn of an HIV-infected mother who is not treated with antiretroviral (ARV) within 4 weeks before delivery and/or who discovers HIV infection at delivery;
    • Low risk: newborn of HIV-infected mother treated with ARV since ≥ 4 weeks before delivery).

    Defining the level of risk by measuring HIV viral load:

    • High risk: VL>1000 cp/mL
    • Low risk: VL≤ 1000 cp/mL

Questions about this trial

What is this clinical trial studying?

An observational study of Mother to Child HIV Transmission, run by ANRS, Emerging Infectious Diseases at 1 site in Guinea.

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 8 inclusion and 10 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: finished, as of the sponsor's last update on 16 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Guinea. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluate the operationally of introducing the measurement of viral load in HIV-1 infected mothers at delivery by POC (time frame: Day 0 to day 2). 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 16 Oct 2026.
