Trial summary

Antiretroviral therapy of the mother and of the newborn associated with alternative schemes of breastfeeding can reduce these transmission rates to 1%. The diagnosis of HIV infection in newborns is based on PCR for detection of viral genetic material, a procedure that is expensive and of complex logistics. Read more about this study

About this study

Antiretroviral therapy of the mother and of the newborn associated with alternative schemes of breastfeeding can reduce these transmission rates to 1%. The diagnosis of HIV infection in newborns is based on PCR for detection of viral genetic material, a procedure that is expensive and of complex logistics. Tests based on detection of antibodies are faster and cheaper but cannot distinguish infected child or maternal antibodies passed to the fetus through the placenta. Nevertheless, the so-called rapid tests have been implemented in the network of health services because of their simplicity and performance comparable to conventional tests. DPP HIV 1/2 test, produced by Bio-Manguinos/Fiocruz, usage is limited by the manufacturer to over 24 months of age children, though the guidelines control programs already recommend the use from 18 months in Brazil and 9 months in other countries. Data on the accuracy of the rapid test under 24 months of age are scarce. This proposal aims to assess the performance of rapid tests produced by Bio-Manguinhos in diagnostic protocols for HIV infection in children 9-24 months old, in order to obtain empirical data to support the current recommendations on rapid tests, particularly in countries with limited access to tests that require specialized laboratories. The validation of rapid HIV testing in other age groups is a requirement of the national regulatory authorities, and has important implications for programs to control HIV-AIDS in populations from countries with limited access to specialized laboratory resources. The use of the rapid test can also represent a significant reduction in costs, as it allows limiting the use of molecular tests to complex and expensive confirmation cases.

Read the detailed description

It concerns a study with a sample composed of children born from HIV positive mothers, age between 9 and 24 months old, with confirmed or discarded infection for HIV determined by molecular testing. Samples from the volunteers will be subjected to rapid tests and serological and molecular reference tests.

After obtaining consent from the child's guardian,a brief interview will take place with completing the questionnaire of inclusion in the research. Then, the collection of fluid in the oral cavity as well as the fingerstick puncture will be conducted for the HIV rapid tests procedures.

The results of the rapid tests will be compared with the ones from the molecular testing and the concordance will be determined for each age group separately.

The study has being conducted by four clinical research sites at Brazil, distributed in three different states, and a clinical research site at Tanzânia: Instituto Fernandes Figueira (IFF - Fiocruz) at Rio de Janeiro; Hospital Geral de Nova Iguaçu (HGNI) at Rio de Janeiro, Fundação de Medicina Tropical Doutor Heitor Vieira Dourado (FMT-HVD) at Amazonas; Secretaria de Estado de Saúde Pública do Pará (URES - Materno Infantil - UREMIA) at Pará and National Institute for Medical Research (NIMR) at Tanga in Tanzania.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • This was an observational study of medical devices (rapid tests) used for the HIV diagnosis in children up to 2 yearsBehavioural

    These rapid tests are based on lateral flow immunochromatography technology, in which a nitrocellulose membrane is impregnated with the antigen of interest. The patient sample (blood, serum, plasma, oral fluid, etc.) is applied in this membrane which facilitates the interaction of antibodies in the sample with the antigens on the membrane. This reaction becomes visible to the naked eye thanks to a color developing revelator.

    The entire testing process, from sample collection to result reading takes no more than 40 minutes and does not depend on laboratory facilities.

Questions about this trial

What is this clinical trial studying?

An observational study of Human Immunodeficiency Virus Transmission and Human Immunodeficiency Virus, run by The Immunobiological Technology Institute (Bio-Manguinhos) / Oswaldo Cruz Foundation (Fiocruz) at 1 site in Brazil.

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 1 inclusion and 1 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 13 Jun 2019. 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 Brazil. 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 Luiz Antonio J Camacho, DrPH (+552125982630, luiz.camacho@ensp.fiocruz.br), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Efficacy of the Bio-Manguinhos / Fiocruz Rapid DPP® HIV-1/2 Immunoblot (time frame: Day 1). 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 13 Jun 2019.
