Eligible patients were ≥ 13 years old, with ≥ 9 months on first-line ART, and confirmed adherence at first-- line regimen failure. Conducted at a Northern Indian tertiary hospital, this 5 year follow-up examined virological outcomes and drug resistance. Follow-up included initial viral-load (VL) and CD4 testing at 6-months, subsequent VL testing every 6-12 months, clinical evaluations, and infection screenings. Data on demographics, treatment history, virological-failure (VF), and drug-resistance testing (DRT) (Viroseq HIV-1 genotyping-system) were analysed using Kaplan-Meier and Competing-risk analysis, with appropriate censoring and imputation for events like death, transfer-out, treatment discontinuation/ interruption, loss to follow-up (LTFU), or ART-regimen change.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;219 PLH shifted to ritonavir-boosted PI based second-line ART after 68 (median) months (IQR: 68) of first-line ART exposure and were followed up for 57 (median) months (IQR: 48), totalling 11,548 person-months (PM) of follow-up. Virological outcomes were assessed in 201 PLH. VF cumulative-incidence (Kaplan-Meier-analysis) ranged from 6.9% at 36 months to 15.9% at 60 months. Imputation scenarios showed a potential range, with worst-case incidences of 16.2% at 36 months and 29.4% at 60 months. Cumulative-incidence function (CIF) of VF (Competing-risk-analysis) ranged from 6.5% at 36 months to 12.7% at 60 months.

Due to the increasing age of people living with HIV, the detection and management of comorbidities has become more important.</p><p><strong>Objective: </strong>In this study, we aimed to detect the prevalence of Nonalcoholic Fatty Liver Disease (NAFLD) and associated risk factors among people living with HIV followed up in our center.</p><p><strong>Methods: </strong>This single-center, cross-sectional study included people living with HIV, on ART for ≥1 year and virologic suppression for ≥6 months, presenting for routine follow-up between October 1, 2021, and April 1, 2022. Participants with a concurrent etiology for hepatic steatosis were excluded. Transient elastography (TE) was performed. NAFLD was defined as a controlled attenuation parameter (CAP) ≥248 dB/m; significant fibrosis (≥F2) was defined as liver stiffness measurement ≥7.1 kPa.</p><p><strong>Results: </strong>A total of 102 people living with HIV (84% men; median age, 39 years [IQR 33-52.5]) were enrolled. The treatment regimen of all participants included a nucleos(t)ide reverse transcriptase inhibitor and an integrase strand transfer inhibitor. TE analysis indicated NAFLD in 28 (27.5%) and fibrosis in 9 (8.8%; 6 with NAFLD) participants. In multivariable analysis, type two diabetes (OR:5.7 [95% CI 1.4-22.2], p=0.013), larger waist circumference (OR:1.1 [95% CI 1.03-1.16], p=0.007), higher alanine aminotransferase (OR:1.05 [95% CI 1.01-1.09], p=0.018), and higher thyroid stimulating hormone (OR:3.1 [95% CI 1.4-6.8], p=0.005] were independently associated with NAFLD.</p><p><strong>Conclusion: </strong>We observed a significant prevalence of NAFLD among people living with HIV followed up in our center. The high prevalence of NAFLD in our sample mirrors that of the general population, likely due to rising rates of metabolic dysfunction. Our findings highlight the importance of timely screening and implementation of management strategies for NAFLD in this population.</p>","PeriodicalId":10911,"journal":{"name":"Current HIV Research","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143699906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
