This study describes patterns of acquired drug resistance (ADR) and potentially active drugs for subsequent ART regimens in individuals failing treatment in Cameroon. We conducted a cross-sectional, laboratory-based sentinel study among ART-failing individuals from October 2022 through April 2023 at the \"Chantal Biya\" International Reference Centre, Yaoundé-Cameroon. Individual samples with confirmed virological failure were sequenced in HIV-1 protease and reverse-transcriptase genes using Sanger sequencing and analysed using Stanford HIVdatabase.v.9.4. Overall, 203 individuals were enrolled, median [IQR] age 37 [16-47] years with 58.1% (118/203) being female. Median [IQR] duration on ART was 10 [6.9-13.3] years, with majority failing second-line (78.7%; 160/203). HIVDR rate was 85.3% (29/34) and 88.1% (140/160) in those failing first-line and second-line therapy respectively (p = 0.7). NNRTI, NRTI and PI/r resistance in individuals failing first-line ART was 85.3% (9/34), 82.4% (28/34) and 2.9% (1/34) respectively. In second-line failure, NNRTI, NRTI and PI/r resistance was 86.8% (138/160), 84.9% (135/160) and 47.17% (75/160) respectively. NRTI-NNRTI dual-class-resistance was 82.4% (28/34) after first-line and 84.3% (134/160) after second-line (p = 0.842), while triple-class-resistance was 2.9% (1/34) after first-line and 45.3% (72/160) after second-line (p < 0.0001). After first-line, TDF and AZT maintained potential efficacy in respectively 53.4% (18/34) and 46.7% (16/34) of individuals, while 46.7% (16/34) had cross-resistance to second-generation NNRTI. After second-line failure, 95.6% (153/160) maintained DRV/r efficacy, as compared to 67.3% for ATV/r (p < 0.0002), 73.9% for LPV/r (p < 0.0002), and 34.7% (56/160) for RPV/DOR. Among ART-failing individuals in Cameroon, levels of ADR are high with significant levels of cross-resistance to second-generation NNRTI, hence potentially jeopardizing the use of long-acting cabotegravir/rilpivirine. Furthermore, HIVDR testing could be considered from first-line failure in such settings, but chiefly following second-line failure wherein triple-class-resistance is common and calls for novel antiretrovirals in similar LMICs.</p>","PeriodicalId":7503,"journal":{"name":"AIDS Research and Therapy","volume":"22 1","pages":"97"},"PeriodicalIF":2.5,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12487141/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These goals-ensuring that 95% of people living with HIV know their status, 95% of those diagnosed are receiving treatment, and 95% of those receiving treatment achieve VLS-represent a bold vision to end HIV as a public health threat by 2030.

It further examines the potential consequences of funding cuts for health system resilience and epidemic control.

Serum albumin is therefore an independent factor for the prediction of disease progression and mortality in People Living With HIV.</p><p><strong>Methods: </strong>This was a cross-sectional study conducted at Lira Regional Referral Hospital in northern Uganda that targeted HIV-positive outpatients attending the ART clinic with a sample size of 373 patients. Data were collected through structured interviews and laboratory tests in which the serum albumin concentration, viral load, and CD4 count were measured.</p><p><strong>Results: </strong>The prevalence of hypoalbuminemia was 19.6% (73/373). A moderate positive correlation was observed between the serum albumin concentration and the CD4 count (rs = 0.43, p < 0.001). Patients with no formal education [AOR = 2.03, 95%CI = 1.69-2.07, P = 0.03] were 2.03 times more likely to have hypoalbuminemia than those who had a tertiary/university education level. The odds of having hypoalbuminemia [AOR = 2.17, CI = 1.80-3.06, P = 0.02] were 2.17 higher among HIV-infected patients who were naïve ART than among those who were on ART. Additionally, the odds of having hypoalbuminemia [AOR = 2.91, CI = 2.13-3.66, P = 0.01] were 2.91 higher among HIV-infected patients who were in stage four than among those who were in stage 1.</p><p><strong>Conclusion: </strong>Hypoalbuminemia prevalence was high in PLWHIV, and a moderate positive correlation was found between the serum albumin level and the CD4 cell count.
