About this study
Official title: ANRS EP59 CLEAC : Physiopathological Study of Immunovirological Evolution of Perinatally HIV-1 Infected Children Depending on Early (Before 6 Months) or Late (After 2 Years) Antiretroviral Therapy Introduction.
The study aims to define and compare the immunological characteristics (lymphocyte subpopulations, specific immunity against HIV, lymphocyte activation, inflammatory parameters) and the virological characteristics (study of viral reservoir) between 2 groups of vertically-HIV-1-infected children, between 5 and 17-year-of-age, who started cART before 6 months-of-age ("early treatment" group) or after 24 months-of-age ("late treatment" group) with an initial virologic success (HIV-1 RNA <400 copies / mL reached no later than 24 months after the start of cART), whatever the later evolution of the viremia.
Moreover, the viral reservoir will be deeply characterized in 10 children (5 patients in each group) with sustained control of the HIV-1 viremia under cART (≥ 90% of HIV-1 RNA measures <400 copies /mL): quantification of the reservoir in the lymphocyte subpopulations and study of the inductibility of the viral reservoir.
Read the detailed description
This is a cross-sectional study, multicenter, without direct benefit, among vertically HIV-1 infected children, aged 5 to 17 years, followed in centers participating in the ANRS CO10 EPF cohort located in Ile-de-France. Eligible children are not necessarily included in the cohort. The sample will consist of two age groups of equal size (5-12 years and 13-17 years).
Patient recruitment will be conducted in the centers of the ANRS CO10 EPF cohort located in Ile de France (Paris area). 80 children will be included, previously included or not in the ANRS CO10 EPF cohort. Our investigations will involve two blood samples, taken during two successive visits of the children in the hospitals where they are usually followed. Finally, a third blood sample will be taken during a third visit only for the 10 children participating in the substudy of the viral reservoir. All medical data since birth will be prospectively collected for children included in the ANRS CO10 EPF cohort, and retrospectively collected in the other cases.

Measured: Baseline
Immune status
The immune status will be defined by inflammatory parameters : cytokines and chemokines

Measured: Baseline
Secondary outcomes (3)
Comparison of immune and virological statuses of early and late treatment groups
Two groups of vertically-HIV-1-infected children, between 5 and 18-year-of-age, will be compared: the "early treatment" group that comprises children who started HAART before 6 months-of-age, and the late treatment" group those who started HAART after 24 months-of-age.
Measured: Baseline
Viral reservoir : lymphocyte subpopulation
Total HIV- DNA will be quantified by ultrasensitive PCR in CD4 T cell subsets sorted according their differenciation status for 10 children (5 patients in each group) with sustained control of the HIV-1 viremia under HAART ( ≥ 90% of HIV-1 RNA measures <400 copies / ml).
Measured: One year after baseline
Viral reservoir : inductibility
Inductibility of the viral reservoir will be quantified by ultrasensitive HIV-RNA RT- PCR in supernatants after coculture of CD4 T cells.
Measured: One year after baseline

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The study aims to define and compare the immunological characteristics (lymphocyte subpopulations, specific immunity against HIV, lymphocyte activation, inflammatory parameters) and the virological characteristics (study of viral reservoir) between 2 groups of vertically-HIV-1-infected children, between 5 and 17-year-of-age, who started cART before 6 months-of-age ("early treatment" group) or after 24 months-of-age ("late treatment" group) with an initial virologic success (HIV-1 RNA <400 copies / mL reached no later than 24 months after the start of cART), whatever the later evolution of the viremia.
Moreover, the viral reservoir will be deeply characterized in 10 children (5 patients in each group) with sustained control of the HIV-1 viremia under cART (≥ 90% of HIV-1 RNA measures <400 copies /mL): quantification of the reservoir in the lymphocyte subpopulations and study of the inductibility of the viral reservoir.

Results are not available in the source record.
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?
Immune status (time frame: Baseline). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
