简要总结
A community-based Phase III, cluster randomized trial that seeks to determine the 24 week survival with retention in care of point of care CD4 testing with visitect and an enhanced package of screening and prophylaxis for opportunistic infections among patients with advanced HIV disease.
详细描述
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

研究组 & 干预措施
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.
干预措施: Enhanced care package (Other)
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.
结局指标
主要结局
24-week survival with retention in care
时间窗: 24 weeks
Comparison will be made between study arms of those who receive POC CD4 testing vs. those who receive standard flow cytometry, and those who receive the enhanced package of OI screening and prophylaxis, vs. those who receive the current WHO standard.
次要结局
- Evaluate sensitivity and specificity of the different TB point of care tests.(24 weeks)
- Incidence of OIs and associated hospitalization and mortality(Six months)
- Tolerability and adherence to prophylaxis regimen and associated grade 3 to 5 adverse events(24 weeks)
