Moving toward test and start: learning from the experience of universal antiretroviral therapy programs for HIV-infected pregnant/ breastfeeding women.

: In 2015, the WHO recommended universal antiretroviral therapy (ART) for all people living with HIV after two randomized controlled trials revealed lower rates of mortality and serious illnesses among people living with HIV receiving immediate ART compared with those receiving deferred ART. Many countries in sub-Saharan Africa rapidly adopted this guidance and are implementing 'test and start' programs.As this work begins, lessons learned from prevention of mother-to-child transmission Option B+ programs can inform decisions for new universal HIV treatment programs. The Option B+ approach involved initiation of lifelong treatment for all HIV-infected pregnant and breastfeeding women. Since its inception in Malawi in 2011 and WHO endorsement in 2012, widespread scale-up of Option B+ prevention of mother-to-child transmission programs in most resource-limited countries has resulted in a dramatic increase in ART coverage for HIV-infected pregnant and breastfeeding women.Despite the overall success of the Option B+ universal lifelong treatment approach, program and operational research data highlight the need for additional focus on strategies to retain women in care. In this commentary, we highlight program considerations and lessons learned from Option B+ implementation experience in resource-limited countries, which may help guide decisions and enhance the quality of general 'test and start' programing.

Performance characteristics of finger-stick dried blood spots (DBS) on the determination of human immunodeficiency virus (HIV) treatment failure in a pediatric population in Mozambique.

Quantitative plasma viral load (VL) at 1000 copies /mL was recommended as the threshold to confirm antiretroviral therapy (ART) failure by the World Health Organization (WHO). Because of ongoing challenges of using plasma for VL testing in resource-limited settings (RLS), especially for children, this study collected 717 DBS and paired plasma samples from children receiving ART ≥1 year in Mozambique and compared the performance of DBS using Abbott's VL test with a paired plasma sample using Roche's VL test. At a cut-off of 1000 copies/mL, sensitivity of DBS using Abbott DBS VL test was 79.9%, better than 71.0% and 63.9% at 3000 and 5000 copies/mL, respectively. Specificities were 97.6%, 98.8%, 99.3% at 1000, 3000, and 5000 copies/mL, respectively. The Kappa value at 1000 copies/mL, 0.80 (95% CI: 0.73, 0.87), was higher than 0.73 (95% CI: 0.66, 0.80) and 0.66 (95% CI: 0.59, 0.73) at 3000, 5000 copies/mL, respectively, also indicating better agreement. The mean difference between the DBS and plasma VL tests with 95% limits of agreement by Bland-Altman was 0.311 (-0.908, 1.530). Among 73 children with plasma VL between 1000 to 5000 copies/mL, the DBS results were undetectable in 53 at the 1000 copies/mL threshold. While one DBS sample in the Abbott DBS VL test may be an alternative method to confirm ART failure at 1000 copies/mL threshold when a plasma sample is not an option for treatment monitoring, because of sensitivity concerns between 1,000 and 5,000 copies/ml, two DBS samples may be preferred accompanied by careful patient monitoring and repeat testing.

Translating Technical Support Into Country Action: The Role of the Interagency Task Team on the Prevention and Treatment of HIV Infection in Pregnant Women, Mothers, and Children in the Global Plan Era.

While the Interagency Task Team on the Prevention and Treatment of HIV Infection in Pregnant Women, Mothers, and Children (IATT) partnership existed before the Global Plan Towards the Elimination of New HIV Infections Among Children by 2015 and Keeping Their Mothers Alive (Global Plan), its reconfiguration was critical to coordinating provision of technical assistance that positively influenced country decision-making and program performance. This article describes how the Global Plan anchored the work of the IATT and, in turn, how the IATT's technical assistance helped to accelerate achievement of the Global Plan targets and milestones. The technical assistance that will be discussed addressed a broad range of priority actions and milestones described in the Global Plan: (1) planning for and implementing Option B+; (2) strengthening monitoring and evaluation systems; (3) translating evidence into action and advocacy; and (4) promoting community engagement. This article also reviews the ongoing challenges and opportunities of providing technical assistance in a rapidly evolving environment that calls for ever more flexible and contextualized responses. The effectiveness of technical assistance facilitated by the IATT was defined by its timeliness, evidence base, and unique global perspective that built on the competencies of its partners and promoted synergies across program areas. Reaching the final goal of eliminating vertical transmission of HIV infection and achieving an AIDS-free generation in countries with the highest HIV burden requires that the IATT partnership and technical assistance remain responsive to country-specific needs while aligning with the current programmatic reality and new global goals such as the Sustainable Development Goals and 90-90-90 targets.
