MONITORING ‘LAZARUS’ WAS EASY….. …MONITORING 'UNDETECTABLE’ IS MORE CHALLENGING
Virological monitoring detects treatment failure earlier than clinico-immunological monitoring
Viremic patients can re-suppress following an adherence intervention

The importance of preserving first line, affordable, robust, one-pill-a-day regimens
Ref: Untangling the Web of ARV Price Reductions 16th Edition, July 2013
Implementation is done in support of, and in collaboration with, the Ministries of Health and reference laboratories
The UNITAID-funded MSF diagnostics project
• Goal: Improved clinical outcomes for PLWHA in resource-constrained settings through models of care for optimal use of PoC CD4, laboratory-based and PoC viral load and EID testing
• 3 year project – $28.7 million• Eight sites in seven countries – Lesotho, Malawi (2), Mozambique, South Africa,
Swaziland, Uganda and Zimbabwe.• MSF field missions will compare the feasibility, outcomes and cost-effectiveness
of point-of-care testing versus district- or regional-level laboratory-based testing for CD4 and viral load & EID through comparative operational research
• MSF Access Campaign will perform market intelligence work and ensure price transparency along the value chain
• Evidence-based findings will be disseminated and used to influence policy• Expected results on market: helping the market launch of products, increasing
competition, decreasing pricing, breaking monopolies
Operational Research Framework
1. Policy and research landscape review2. Descriptive cohort and cross-sectional studies
• Cohort/cascade outcomes,• Prevalence of failure and 2nd line• Prevalence of VL ranges in treated patients, including thresholds• Prevalence of genotypic resistance
3. Impact and costs of VL vs CD4 monitoring strategies4. Validation and costing of tools and approaches
• Improved lab-based options• PoC tools• M-health tools• Adherence support
5. Comparison of different algorithms using validated tools6. M&E
Plans to incorporate the new WHO recommendations
MSF is pleased with, and intends to provide support to implement, the new WHO guidelines by:
1. Demonstrating HOW to implement the guidelines2. Demonstrating the ADDED VALUE of the new
guidelines3. Supporting QUALITY (scale-up without mess-up)4. Working with partners to SUPPORT implementation
(e.g. so that Ministries of Health can make informed decisions) and with WHO wherever possible
How best practices will be shared with, and disseminated by, WHO
Evidence-based results provided to the WHO wrt POC CD4 testing will include:1. Use of point-of-care CD4 to plug the leaky cascade between test and treat
Evidence-based results provided to the WHO wrt routine viral load monitoring will include:
2. Feasibility of real-world implementation of tools and best tools for RLS (including the use of dried blood spots and m-health)
3. Possibilities for decentralisation and task shifting4. Benefits of routine VL testing plus adherence support vs targeted VL testing
and clinico-immunological testing5. Dropping CD4 monitoring of treated patients who are virologically suppressed6. In what situations or contexts point-of-care testing makes sense7. Best algorithm and threshold for diagnosing treatment failure8. Modelling data that is built on credible, real-world data (so that long-term
outcomes can be modelled)9. Psychological benefits to patients (e.g. motivation, empowerment)10. Costing: cost-effectiveness of different strategies as well as cost-saving methods
e.g. sample pooling11. Transparent and comprehensive in-country pricing and market intelligence data
