Opis
Inclusion Criteria:
- PTC: Viremic people living with HIV (HIV-RNA >1000c/mL) before ART initiation. Plasma HIV-RNA off ART ≤400c/mL at least 2 times at ≥24weeks apart and at ≥2/3rds of HIV-RNA measurements. Elite PTC with ≤50c/mL will be identified.
- Post intervention controller (PIC): People living with HIV from ATI or MAP studies who meet the PTC criteria as per ATI/MAP study defined. Additional stratification occurs according to the duration of and level of suppressed plasma HIV-RNA (e.g. ≤400c/mL off ART at least 2 times for ≥8 weeks apart). This is done to streamline PIC definitions and capture PIC inMAP studies with an ART pause of less than 24 weeks.
- Controls: non-controllers (NC) with plasma HIV-RNA >1000 c/mL after ART interruption.
- Suppressors: viremic people living with HIV (HIV-RNA >1000c/mL) before ART initiation who became HIV-RNA <50c/mL suppressed on ART, remained on ART, and never had viral rebound.
Exclusion Criteria:
- 1.Documented refusal of data use for research

PTC
Viremic PWH (HIV-RNA >1000c/mL) before ART initiation.
Plasma HIV-RNA off ART ≤400c/mL at least 2 times at ≥24weeks apart and at ≥2/3rds of HIV-RNA measurements.
Elite PTC with ≤50c/mL will be identified

|---|---|---|
|
Intact proviral HIV DNA reservoir size in PTC and PIC before and during ATI
Ramy czasowe: 1 year
|
Reservoir size will be measured as intact proviral HIV DNA and reported as log copies per 10^6 CD4+ cells.
Reservoir size in PTC, PIC, and NC before and after ATI will be described according to data distribution.
|
1 year
|
|
Total integrated HIV DNA reservoir size in PTC and PIC before and during ATI
Ramy czasowe: 1 year
|
Reservoir size will be measured as total integrated HIV DNA and reported as log copies per 10^6 PBMC.
Reservoir size in PTC, PIC, and NC before and after ATI will be described according to data distribution.
|
1 year
|
|
Inducible HIV reservoir size in PTC and PIC before and during ATI
Ramy czasowe: 1 year
|
Reservoir size will be measured as inducible HIV and reported as log HIV RNA or HIV DNA copies.
Reservoir size in PTC, PIC, and NC before and after ATI will be described according to data distribution.
|
1 year
|
|
Time from the start of ATI until first measurement of HIV RNA >50 copies/mL in PTC and PIC.
Ramy czasowe: 1 year
|
A survival analysis will be done for all PTC, PIC and NC who have been sourced from ATI trials.
Baseline will be set as the start of the treatment interruption.
Time will be noted in weeks until first measurement of HIV-RNA >50 copies/mL for all study participants.
Levels correspond to elite controller definition (Deeks & Walker, 2007), PTC definition, and level below which HIV onward transmission rarely occurs (Gray et al., 2001).
Analysis is by Kaplan Meier and Cox Proportional Hazard models with loss of viral control as event.
Independent variables can be timing of ART initiation, duration of ART, HIV cure intervention (if any), demographic parameters (sex, age, place of birth, country of residence), viral dynamics (subtype, reservoir size) and immune characteristics (cd4+ count, cd8+ count, cd4/cd8 ratio).

Number and severity of adverse events during and after ATI.
Ramy czasowe: 1 year
|
Medical events in PTC, PIC and NC recorded in the clinical file will be described using the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
If medical events have been reported using varied terminology in the ATI trials, two separate evaluators will reclassify them using CTCAE v5.0 terminology.
In instances of conflicting classifications, an impartial researcher will make the final determination.
|
1 year
|
|
Biobank with samples from PTC, PIC and NC including sampling time points and material available.
Ramy czasowe: 1 year from screening
|
Available samples will be indexed from previously performed ATI trials.
An inventory will be made of the number of samples, type, volume, time of sampling, sampling technique and storage medium.
|
1 year from screening
