Description détaillée
The study will be carried out in a population of HIV-infected adults with advanced HIV disease (CD4 <200 cells/µL) in Uganda. It will be a Randomized controlled trial, Phase III in Uganda over a duration of 5 years assessing 24 weeks survival with retention in care. @4 clinic will be randomized to either receive the enhanced package or standard of care.
Description of Intervention Arm
- Point-of-care CD4 testing via Visitect (point of care semi Quantitaive CD4 LFA) lateral flow assay (LFA)
Enhanced package of opportunistic infection screening and prophylaxis for CD4<200, including:
- FujiFilm SILVAMP TB LAM (FujiLAM)
- Isoniazid (INH) + rifapentine: 1 month of therapy for latent TB(Tuberculosis) infection
- Cryptococcal Antigen semi-quantitative (CrAg-SQ) LFA (Immy)
- Treatment for disseminated CNS cryptococcal infection if high blood CrAg titer (>3+ CrAg SQ)
Description of Standard of Care Arm
- CD4 testing by flow cytometry
WHO recommended package of OI screening and prophylaxis, including:
- Urine TB LAM
- INH ( isoniazid 6 months)
- CrAg LFA
- Fluconazole for asymptomatic CrAg+ o 800mg daily x 2 weeks, then 400mg daily x 8 weeks, then 200mg daily.
Problem statement: Current lab-based CD4 testing results in a delay to either start ART(Antiretroviral therapy) or a delay in screening persons with low CD4s for OIs. At present, prioritization has been on ART initiation without systematic OI screening. Those with subclinical OIs started on ART unmask their OIs, with hospitalization / deaths for OIs such as cryptococcosis and TB.
We hypothesize that with point of care CD4 testing, same-day OI screening can occur, yet not interrupt prompt ART initiation for those at low risk (FujiLAM and CrAg-SQ negative) of unmasking immune reconstitution syndrome.
We hypothesize that point-of-care CD4 testing will improve 6-month survival by reducing lag time in CD4 results, thereby facilitating ART initiation, retention-in-care, and OI screening and prophylaxis.
We hypothesize that enhanced screening with the point-of-care FujiLAM, CrAg-SQ LFA, with enhanced prophylaxis for TB (1 month of INH and rifapentine) and with treatment for disseminated CNS cryptococcal infection in those CrAg+ with high titers (>3+) will improve 6-month survival compared to current WHO-recommended standard practice in persons with advanced HIV disease.

Intervention / Traitement |
|---|---|
|
Expérimental: intervention(Enhanced package of care) Arm
The patients with advanced HIV disease that receive HIV care at the intervention clinics will receive the enhanced intervention package which will include: point of care CD4 testing with visitect, screening for TB and cryptococcal meningitis using Fujifilm LAM and semiquantitative crAg LFA respectively and pre-emptive treatment with isoniazid and rifapentine for one month.
Those with a high crAg titers will receive treatment for CNS cryptococcal disease.
|
The intervention is an improved package of care for patients with advanced HIV disease with point of care CD4 testing, more sensitive screening tests for opportunistic infections and more intensive pre-emptive treatment for opportunistic infections
|
|
Aucune intervention: Standard of care Arm
The patients with advanced HIV disease that receive HIV care at the standard of care clinics will receive the usual routine HIV care as per the Uganda national guidelines.
That is CD4 testing with flowcytometry or other CD4 testing modalities available, screening for TB and cryptococcal meningitis using Alere LAM and crAg LFA respectively and pre-emptive treatment with isoniazid and rifapentine for 3-6 month.
Treatment of all asymptomatic crAG positives with fluconazole as per guidelines.
