We aimed to estimate the prevalence of unsuppressed viral load and identify the factors contributing to this issue among children and adolescents living with HIV on ART in sub-Saharan Africa.</p><p><strong>Methods: </strong>In this systematic review and meta-analysis, we assessed data from Web of Science, Google Scholar, Scopus, PsycINFO, Embase, PubMed (MEDLINE), EBSCOhost Research Databases, and Wiley Online Library, as well as grey literature searches. We included studies published between Jan 1, 2010, and Nov 30, 2024 that focused on children and adolescents (aged <20 years) on ART in sub-Saharan Africa and reported on factors related to viral load suppression, defined by a viral load of less than 1000 copies per mL. Eligible studies included observational and interventional designs. Data appraisal and extraction were conducted by two independent reviewers from the author group, with summary data extracted from published reports. The primary outcome assessed was the prevalence of unsuppressed viral loads, with meta-analysis performed using STATA software to calculate prevalence and associated factors. The study is registered with PROSPERO (CRD42023451212).</p><p><strong>Findings: </strong>From an initial 13 121 identified articles, 52 studies involving 169 949 children and adolescents on ART met the inclusion criteria. Prevalence of unsuppressed viral load among children and adolescents in sub-Saharan Africa was 26·47% (95% CI 23·06-29·87); specifically, 26·01% (20·51-31·52) for studies in children (<15 years), 24·76% (17·36-32·16) for studies in adolescents (10-19 years), and 28·52% (23·33-33·72) for studies in a combined group of children and adolescents. Factors associated with unsuppressed viral load included younger age (<5 years), male sex, rural residence, orphan status, attendance at a level 1 or 2 health-care facility, HIV status not disclosed, poor ART adherence, advanced WHO clinical stage of HIV, low CD4 cell counts, history of opportunistic infections, nevirapine-based treatment regimen, drug substitution history, and not receiving co-trimoxazole prophylaxis.

Increasingly, single-strategy interventions are giving way to multicomponent approaches to respond to nuances in adherence behaviour. However, determining which effective strategy to offer and to whom, when, and how remain pressing questions if professionals in the field (eg, researchers, clinicians, and community health workers) are to reach the UNAIDS 95-95-95 goals in the recent context of decreased funding.

Since the genetic barrier to resistance of dolutegravir is not impenetrable, rising rates of dolutegravir resistance among those with virological failure on this drug regimen have been reported. Risk factors for dolutegravir resistance include treatment experience, having background resistance to the nucleoside reverse transcriptase inhibitors in the regimen, switching to tenofovir, lamivudine, and dolutegravir when viraemic on a former regimen, previous experience with first-generation INSTIs, and being on dolutegravir monotherapy or dual therapy, with rates higher in children than in adults. HIV drug resistance does not emerge if selective drug pressure is not present, so some exposure to the ART regimen with virological failure is associated with higher rates of resistance than complete non-adherence. Detectable objective metrics of adherence (eg, ART drug concentrations in urine, plasma, dried blood spots, and hair) have been associated with high levels of viral resistance and can be used to triage who needs resistance testing the most.","PeriodicalId":48725,"journal":{"name":"Lancet Hiv","volume":"70 1","pages":""},"PeriodicalIF":16.1,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144341085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lenacapavir pre-exposure prophylaxis (PrEP) is also unlikely to drive population-level lenacapavir resistance given the rarity of breakthrough infections and the reduced replication capacity of most lenacapavir-resistant variants, which most likely reduces their transmission potential. Conversely, the risk of acquiring lenacapavir-resistant HIV-1 while receiving lenacapavir PrEP is likely to remain extremely low, as lenacapavir-associated drug-resistance mutations are rare among individuals without previous lenacapavir exposure, and widespread use of lenacapavir-based regimens remains years away.

Improved characterisation of transmitted integrase resistance, its detection, and its clinical impact will guide future recommendations for clinical decision making. Balancing the need to protect this important drug class against concerns about resource allocation and care complexity presents a substantial challenge. Shifting the responsibility to providers to decide whether and when to test for integrase resistance before ART initiation can be problematic, particularly given the uncertainty around the need to reassess related available recommendations.
