HIV drug resistance

This concept note describes the methods used to assess the prevalence of any HIVDR and HIVDR by PMTCT exposure among children less than 18 months of age using remnant dried blood spot specimens from early infant diagnosis over a 12-month period
The aim of the operational framework is to ensure 1) accurate collection, handling, shipment and storage of specimens collected in countries implementing HIV drug resistance surveillance; and 2) the availability of quality-assured HIV genotyping laboratory services producing comparable and reliable ...results at the national, regional and global levels.
This publication updates the WHO HIVResNet HIV drug resistance laboratory operational framework published in 2017 and reflects technical and strategic developments over the past three years.

Regional action plan 2019-2023
WHO recommends that pre-exposure prophylaxis (PrEP) be offered as an additional prevention choice for HIV-negative individuals at substantial risk of HIV infection as part of combination prevention approaches.
HIV drug resistance has been rarely reported among PrEP users who tested HIV positive i...n randomized controlled trials or open-label studies. However, PrEP-selected HIV drug resistance could potentially negatively impact the effectiveness of treatment options among PrEP users who acquire HIV, since there is a potential for overlapping resistance profiles between antiretroviral drugs used for both PrEP and first-line antiretroviral therapy.

The goal of this Global Action Plan is to articulate synergistic actions that will be required to prevent HIVDR from undermining efforts to achieve global targets on health and HIV, and to provide the most effective treatment to all people living with HIV including adults, key populations, pregnant ...and breastfeeding women, children and adolescents. The Global Action Plan has five strategic objectives: 1) prevention and response; 2) monitoring and surveillance; 3) research and innovation; 4) laboratory capacity; and 5) governance and enabling mechanisms.

This study aimed to understand the patterns of HIV drug resistance in pregnant women in Mozambique. This might help in tailoring optimal regimens for prevention of mother to child transmission of HIV (pMTCT) and antenatal care.
The HIV drug resistance report 2021 summarizes findings from 38 countries that had finalized the surveys by the time of this report and shared data with WHO.
Pretreatment HIVDR to non-nucleoside reverse-transcriptase inhibitors (NNRTI) can affect more than 10% of adults starting therapy and is fo...und up to 3 times more often in people who had previous exposure to antiretroviral drugs. In addition, nearly half of infants newly diagnosed with HIV has HIVDR to NNRTI before initiating treatment.The high levels of observed NNRTI pretreatment HIVDR among emphasize the need to fast-track the transition to WHO-recommended dolutegravir-based ART.

Testing providers
July 2017
Module 10: Testing providers. This module is for people who provide testing services at PrEP sites and laboratories. It offers guidance in selecting testing services, including screening of individuals before PrEP is initiated and monitoring while they ar...e taking PrEP. Information is provided on HIV testing, creatinine, HBV and HCV, pregnancy and STIs.

HIV-1 drug resistance (HIVDR) genotyping is an essential component of the WHO global HIVDR surveillance strategy. Plasma “gold standard” specimen type for HIVDR genotyping, but its use may not be feasible in rural, remote areas in low- and middle-income countries, since preparing and storing it ...require personnel and laboratory infrastructure that are often lacking. An alternative specimen type is dried blood spots (DBS), which can be made without special laboratory processing. DBS are more easily transported than plasma because they can be shipped at ambient temperature as non-hazardous materials using regular mail or courier services.

WHO’s antiretroviral treatment (ART) clinic-based acquired drug resistance survey method yields robust estimates of HIV viral suppression and acquired HIV drug resistance in adults, children and adolescents taking both dolutegravir and non-dolutegravir based regimens.
Results are used to inform A...RT programme decision making regarding optimal ART regimens and support evaluation of programme quality with respect to maximizing viral load suppression and minimizing emergence of resistance in people taking ART.
