Abstract
OBJECTIVE Antiretroviral therapy (ART) containing integrase inhibitors (INSTIs) and/or tenofovir alafenamide (TAF) has been associated with greater weight gain. Yet few studies have delineated between exposure to 'anchor' drugs [protease inhibitors (PI), nonnucleoside reverse transcriptase inhibitors (NNRTI) or INSTIs] and exposure to nucleoside reverse transcriptase inhibitors (NRTIs). DESIGN In this cohort of antiretroviral drug-naive patients who initiated ART from 2008-2022, we analyzed BMI gain for eight contemporary 'anchor' drugs and three contemporary NRTIs during the first 3 years of ART. We censored patients if they stopped, switched, or added another antiretroviral drug to their regimen. METHODS We used generalized estimating equations (GEE) to assess the association between BMI gain and choice of ART and a nonlinear mixed model for the marginal coefficients of determination. We adjusted for time, baseline demographic and HIV-characteristics, and time-updated HIV and substance use-related variables. RESULTS The median BMI gain in 4 194 patients over 3 years was + 1.9 kg/m 2 [interquartile range (IQR) 0.1-4.1]. Most patients were black (55%) and men (77%). Multivariable modeling from 20 528 BMI measurements revealed that the type of ART accounted for just 9% of the predicted BMI change. Only efavirenz (EFV) and tenofovir disoproxil fumarate (TDF) were independently associated with (lower) weight gain but no differences were observed between INSTIs, PIs, and rilpivirine, or between TAF and abacavir. CONCLUSION The choice of initial ART had little impact on weight gain. INSTIs or TAF were not independently associated with weight change after ART initiation, but EFV and TDF were.

Changes in bodyweight after initiating antiretroviral therapy close to HIV-1 seroconversion: an international cohort collaboration. Lancet HIV 2024; 11:e660-e669. [PMID: 39186940 DOI: 10.1016/s2352-3018(24)00183-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Revised: 07/08/2024] [Accepted: 07/11/2024] [Indexed: 08/28/2024]
Abstract
BACKGROUND Understanding the reasons for and consequences of bodyweight change in people living with HIV initiating antiretroviral therapy (ART) is crucial to optimising long-term health and wellbeing. We aimed to examine bodyweight trends and associated factors among individuals with well estimated dates of HIV-1 seroconversion. METHODS In this cohort study, we pooled retrospective data from clinical records of participants in CASCADE aged 16 years and older recruited from clinics in France, Greece, the Netherlands, Spain, Sweden, the UK, and Canada. All participants had well estimated dates of HIV-1 seroconversion, seroconverted between Jan 1, 2007, and Dec 31, 2022 (HIV-1 positive antibody test within 12 months of an HIV-1 negative antibody test, or other laboratory evidence of seroconversion), initiated ART within 1 year of seroconversion, and were previously ART-naive. Participants were followed up to the time of data pooling (May 31, 2023). We modelled bodyweight changes after ART initiation by ART class, BMI categories, and other demographic characteristics using linear mixed models. FINDINGS Of 15 755 potentially eligible participants, 5698 met inclusion criteria. Of those, 5148 (90·3%) were assigned male at birth, 517 (9·1%) were assigned female at birth, and 33 (0·6%) had sex not known. 2778 (48·8%) participants initiated integrase strand transfer inhibitor (INSTI)-based ART regimens, 1809 (31·7%) initiated protease inhibitor-based regimens, and 1111 (19·5%) initiated non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens. The majority of participants were men who have sex with men (MSM; 4519 [79·3%]). Median age at seroconversion was 33·7 years (IQR 26·9-43·2). Bodyweight changes differed significantly by ART class within all baseline BMI categories (BMI <18·5 kg/m2 p=0·026, BMI 18·5-24·9 kg/m2 p<0·0001, BMI 25·0-29·9 kg/m2 p=0·0021, and BMI ≥30·0 kg/m2 p=0·0033; ART class and BMI interaction p=0·011). Participants with BMI less than 30 kg/m2 on regimens including both INSTI and tenofovir alafenamide gained 4·76 kg (95% CI 4·05-5·46) or more at 3 years. Of those with baseline BMI 18·5-24·9 kg/m2, 31·3% (95% CI 29·5-33·1) on INSTI-based regimens, 25·3% (23·0-27·7) on protease inhibitor-based regimens, 20·4% (18·8-22·9) on NNRTI-based regimens, 37·4% (33·9-40·9) on tenofovir alafenamide-based regimens, and 38·4% (34·6-42·1) on tenofovir alafenamide and INSTI-based regimens had gained more than 10% of their baseline bodyweight at 3 years. The greatest 3-year bodyweight gains by individuals on INSTI-based regimens and with BMI 18·5-24·9 kg/m2 were in women (5·63 kg [95% CI 4·92-6·35]), and people originating from sub-Saharan African (5·76 kg [5·06-6·46]), compared with MSM (3·82 kg [3·50-4·13]). INTERPRETATION Our findings suggest a direct effect of INSTIs and tenofovir alafenamide on bodyweight gain, rather than a return to health effect. Given the known risk for cardiometabolic disease, bodyweight management needs to be part of the overall care of individuals prescribed these drugs.

Abstract
Antiretroviral therapy (ART) agents as a determinant of body weight in ART-naïve and ART-experienced persons with human immunodeficiency virus (HIV) (PWH) has become a major focus area in research and clinical settings. Recent studies demonstrating weight-suppressing properties of efavirenz and tenofovir disoproxil fumarate led to re-evaluation of weight gain studies, and a reassessment of whether other agents are weight promoting versus weight neutral. In this review, the authors synthesize recent literature on factors related to obesity, clinical measurements of adiposity, weight gain in ART-naïve and ART-experienced PWH, metabolic consequences of ART and weight gain, and the clinical management of weight gain in PWH.

Abstract
PURPOSE OF REVIEW This review aims to summarize recently published peer reviewed papers on the influence of treatment with Integrase Strand Transfer Inhibitors (InSTI) in people with HIV (HIV) on metabolic health, including weight gain, lipid parameters, glucose homeostasis, and bone health. RECENT FINDINGS InSTI have a mild/moderate effect on weight gain in both antiretroviral (ART) naïve and ART experienced PWH, which is more pronounced in certain groups (i.e. women, people of Black African ethnicity, those with lower socioeconomic status, and older people). The effect on weight is also driven by other components of the ART regimen as well as previous exposure to certain ART. InSTI have a relatively safe profile in terms of lipid parameters and bone health, compared to other ART classes, although some studies suggest a greater risk of insulin resistance and diabetes in PWH using InSTI, especially 2nd generation InSTI. While there is some evidence suggesting a negative impact of InSTI on some aspects of metabolic health (weight gain and glucose homeostasis), they remain the preferred treatment option for most PWH, due to their high efficacy and tolerability. However, an individualised approach to ART choice in PWH should be used in order to avoid negative outcomes in populations at higher risks of metabolic complications.

THE LANCET REGIONAL HEALTH. WESTERN PACIFIC 2024; 49:101143. [PMID: 39092318 PMCID: PMC11293588 DOI: 10.1016/j.lanwpc.2024.101143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 06/14/2024] [Accepted: 06/28/2024] [Indexed: 08/04/2024]
Abstract
Background We compared the efficacy and safety profiles of ainuovirine (ANV), a new-generation non-nucleoside reverse transcriptase inhibitor (NNRTI), with boosted elvitegravir (EVG), both coformulated with two nucleoside reverse transcriptase inhibitors (NRTIs), in people living with HIV-1 (PLWH) who had achieved virological suppression on previous NNRTI-based antiretroviral (ARV) regimen. Methods This study was a multi-centre, randomised, double-blind, active-controlled, non-inferiority trial recruiting PLWH from 10 clinical centres across China. Main inclusion criteria included age of 18-65 years (inclusive), and stably staying on an ARV regimen combining an NNRTI with a two-drug NRTI backbone for at least 12 months. Eligible participants must have maintained plasma HIV-1 ribonucleic acid (RNA) titre below 50 copies per mL confirmed on two successive tests at an interval of at least one month prior to randomisation. Participants were randomly assigned to receive ANV 150 mg plus lamivudine (3TC) 300 mg, and tenofovir disoproxil fumarate (TDF) 300 mg (ANV/3TC/TDF), or cobicistat (Cobi) 150 mg boosted EVG plus emtricitabine (FTC) 200 mg, and tenofovir alafenamide (TAF) 10 mg. The primary efficacy endpoint was the proportion of participants with HIV-1 RNA titre at 50 copies per mL or above at week 48 using the US Food and Drug Administration snapshot algorithm, with a non-inferiority margin of 4 percentage points at a two-side 95% confidence level. This trial is active, but not recruiting, and is registered with Chinese Clinical Trial Registry (ChiCTR), number ChiCTR2100051605. Findings Between October 2021 and February 2022, 923 patients were screened for eligibility, among whom 762 participants were randomized and had received at least one dose of ANV/3TC/TDF (n = 381) or EVG/Cobi/FTC/TAF (n = 381). At week 48, 7 (1.8%) participants on ANV/3TC/TDF and 6 (1.6%) participants on EVG/Cobi/FTC/TAF had plasma HIV-1 RNA titre at 50 copies per mL or above, including missing virological data within the time window (the Cochran-Mantel-Haenszel method, estimated treatment difference [ETD], 0.3%, 95% CI -1.6 to 2.1), establishing the non-inferiority of ANV/3TC/TDF to EVG/Cobi/FTC/TAF. The proportions of participants experiencing at least one treatment-emergent adverse events (AEs) were comparable between the two arms (97.6% versus 97.6%). A small proportion of participants discontinued study drug due to AEs (0.3% versus 0.3%). Serious AEs occurred in 11 (2.9%) participants on ANV/3TC/TDF and 9 (2.4%) participants on EVG/Cobi/FTC/TAF, respectively, none of which was considered related to study drug at the jurisdiction of the investigator. At week 48, participants on ANV/3TC/TDF showed a significantly less weight gain from baseline compared to those on EVG/Cobi/FTC/TAF (least square mean, 1.16 versus 2.05 kg, ETD -0.90 kg, 95% CI, -1.43 to -0.37). The changes in serum lipids from baseline also favoured ANV/3TC/TDF over EVG/Cobi/FTC/TAF. Interpretation In virologically suppressed PLWH on previous NNRTI-based ARV regimen, switch to ANV/3TC/TDF resulted in less weight gain, and improved lipid metabolism while maintaining virological suppression non-inferior to that to EVG/Cobi/FTC/TAF.

Abstract
BACKGROUND We evaluated associations between antepartum weight change and adverse pregnancy outcomes and between antiretroviral therapy (ART) regimens and week 50 postpartum body mass index in IMPAACT 2010. METHODS Women with human immunodeficiency virus (HIV)-1 in 9 countries were randomized 1:1:1 at 14-28 weeks' gestational age (GA) to start dolutegravir (DTG) + emtricitabine (FTC)/tenofovir alafenamide fumarate (TAF) versus DTG + FTC/tenofovir disoproxil fumarate (TDF) versus efavirenz (EFV)/FTC/TDF. Insufficient antepartum weight gain was defined using Institute of Medicine guidelines. Cox-proportional hazards regression models were used to evaluate the association between antepartum weight change and adverse pregnancy outcomes: stillbirth (≥20 weeks' GA), preterm delivery (<37 weeks' GA), small size for GA (<10th percentile), and a composite of these endpoints. RESULTS A total of 643 participants were randomized: 217 to the DTG + FTC/TAF, 215 to the DTG + FTC/TDF, and 211 to the EFV/FTC/TDF arm. Baseline medians were as follows: GA, 21.9 weeks; HIV RNA, 903 copies/mL; and CD4 cell count, 466/μL. Insufficient weight gain was least frequent with DTG + FTC/TAF (15.0%) versus DTG + FTC/TDF (23.6%) and EFV/FTC/TDF (30.4%). Women in the DTG + FTC/TAF arm had the lowest rate of composite adverse pregnancy outcome. Low antepartum weight gain was associated with higher hazard of composite adverse pregnancy outcome (hazard ratio, 1.44 [95% confidence interval, 1.04-2.00]) and small size for GA (1.48 [.99-2.22]). More women in the DTG + FTC/TAF arm had a body mass index ≥25 (calculated as weight in kilograms divided by height in meters squared) at 50 weeks postpartum (54.7%) versus the DTG + FTC/TDF (45.2%) and EFV/FTC/TDF (34.2%) arms. CONCLUSIONS Antepartum weight gain on DTG regimens was protective against adverse pregnancy outcomes typically associated with insufficient weight gain, supportive of guidelines recommending DTG-based ART for women starting ART during pregnancy. Interventions to mitigate postpartum weight gain are needed.

Abstract
Dolutegravir is an integrase inhibitor and is recommended by the World Health Organization as the preferred first-line and second-line human immunodeficiency virus treatment in all populations. Excessive weight gain associated with dolutegravir-based regimens is an emerging issue; however, the long-term metabolic consequences of this effect have not been fully understood. Growing evidence shows that this leads to a higher incidence of hyperglycemia, hypertension, and metabolic syndrome, along with elevated cardiovascular risk. Dolutegravir-based regimens, also associated with greater adipocyte differentiation and greater expression of markers associated with lipid storage, continue to be a problem among patients living with human immunodeficiency virus. The mechanisms by which certain antiretroviral therapy agents differentially contribute to weight gain remain unknown. Some clinical investigators speculate that dolutegravir could interfere with central nervous system appetite regulation (melanocortin-4 receptor) and insulin signaling, or may have better penetration of adipose tissue where they could exert a direct impact on adipose tissue adipogenesis, fibrosis, and insulin resistance. This review summarizes our current understanding of weight gain and fat changes associated with dolutegravir and its possible secondary metabolic comorbidities.

Abstract
We assessed the effectiveness and safety of switching to generic dolutegravir/lamivudine (DTG/3TC) among People living with Human Immunodeficiency Virus (PWH) in Western India. In this single-center, retrospective observational study, PWH, who switched to DTG/3TC, were followed for virologic, immunologic, and clinical effectiveness, and safety, including weight changes, hyperglycemia, and dyslipidemia. Multivariate linear mixed-effects models were used to predict average change in weight adjusted for age, sex, duration of previous antiretroviral (ARV) regimens, and baseline weight. From May 2017 to July 2022, out of 434 PWH switched to DTG/3TC, 304 with at least 1 follow-up visit were included. Median [interquartile range (IQR)] age was 54 (IQR 49-61) years and 70.1% were male. Prevalence of baseline comorbidities was 57.9% (hypertension-41.5%, chronic kidney disease-40.9%, and diabetes mellitus-18.8%). Reasons for switch were affordability (47.4%), desire for simplification (41.8%), ARV toxicities (19.1%), and concern about potential toxicities (10.2%). Median (IQR) duration of follow-up on DTG/3TC was 40 (IQR 31-49) weeks. No virologic failure was observed. Rates of virologic suppression [viral load (VL) ≤20 copies/mL or target not detected (TND)] at 12, 24, 48, 72, 96 and 120 weeks were 95.2%, 95.9%, 90%, 100%, 81.3%, and 88.4%, respectively. Only 9 (3%) PWH permanently discontinued DTG/3TC. Predicted adjusted mean weight gain of +3.3 kg was observed at 96 weeks. Switching from tenofovir disoproxil fumarate (TDF)/emtricitabine or lamivudine (XTC)/non-nucleoside reverse transcriptase inhibitor (NNRTI) and duration on DTG/3TC were significantly associated with weight gain. Apart from trend in worsening hyperglycemia (nine PWH with new onset diabetes), no clinically significant change in lipids and estimated glomerular filtration rate (eGFR) was documented. Switching to DTG/3TC is an effective and safe option among virologically suppressed PWH with high comorbidity burden in India. In view of the several advantages of DTG/3TC, it may be considered for potential scale-up in the right population, both in private and public health care settings in India.

Abstract
BACKGROUND Excessive weight gain affects some persons with HIV after switching to integrase strand transfer inhibitor (INSTI)-containing antiretroviral therapy (ART). We studied associations between CYP2B6 genotype and weight gain after ART switch among ACTG A5001 and A5322 participants. METHODS Eligible participants switched from efavirenz- to INSTI-containing ART, had genotype data, and had weight data at least once from 4 weeks to 2 years post-switch. Multivariable linear mixed effects models adjusted for race/ethnicity, CD4, age, BMI and INSTI type assessed relationships between CYP2B6 genotype and estimated differences in weight change. RESULTS A total of 159 eligible participants switched ART from 2007 to 2019, of whom 138 had plasma HIV-1 RNA < 200 copies/mL (65 CYP2B6 normal, 56 intermediate, 17 poor metabolizers). Among participants with switch HIV-1 RNA < 200 copies/mL, weight increased in all 3 CYP2B6 groups. The rate of weight gain was greater in CYP2B6 poor than in CYP2B6 normal metabolizers overall, and within 9 subgroups (male, female, White, Black, Hispanic, dolutegravir, elvitegravir, raltegravir, and TDF in the pre-switch regimen); only in Hispanic and elvitegravir subgroups were these associations statistically significant ( P < 0.05). Compared to normal metabolizers, CYP2B6 intermediate status was not consistently associated with weight gain. CONCLUSION CYP2B6 poor metabolizer genotype was associated with greater weight gain after switch from efavirenz- to INSTI-containing ART, but results were inconsistent. Weight gain in this setting is likely complex and multifactorial.

Abstract
Rapid advances in the potency, safety, and availability of modern HIV antiretroviral therapy (ART) have yielded a near-normal life expectancy for most people living with HIV (PLWH). Ironically, considering the history of HIV/AIDS (initially called "slim disease" because of associated weight loss), the latest dilemma faced by many people starting HIV therapy is weight gain and obesity, particularly Black people, women, and those who commenced treatment with advanced immunodeficiency. We review the pathophysiology and implications of weight gain among PLWH on ART and discuss why this phenomenon was recognized only recently, despite the availability of effective therapy for nearly 30 years. We comprehensively explore the theories of the causes, from initial speculation that weight gain was simply a return to health for people recovering from wasting to comparative effects of newer regimens vs prior toxic agents, to direct effects of agents on mitochondrial function. We then discuss the implications of weight gain on modern ART, particularly concomitant effects on lipids, glucose metabolism, and inflammatory markers. Finally, we discuss intervention options for PLWH and obesity, from the limitations of switching ART regimens or specific agents within regimens, weight-gain mitigation strategies, and potential hope in access to emerging antiobesity agents, which are yet to be evaluated in this population.

Energy balance and body composition after switch between integrase strand transfer inhibitors and doravirine among people with HIV. J Antimicrob Chemother 2024; 79:179-185.

Abstract
BACKGROUND Integrase strand transfer inhibitors (INSTIs) are associated with excessive weight gain among a subset of persons with HIV (PWH), due to unclear mechanisms. We assessed energy intake (EI) and expenditure (EE) following switch off and onto INSTIs. METHODS PWH with >10% weight gain on an INSTI-based regimen switched INSTI to doravirine for 12 weeks, then back to INSTI for 12 weeks while keeping their remaining regimen stable. Twenty-four-hour EE, EI and weight were measured on INSTI, following switch to doravirine, and upon INSTI restart. Mixed models analysed changes over time. RESULTS Among 18 participants, unadjusted 24 h EE decreased by 83 (95% CI -181 to 14) kcal following switch to doravirine, and by 2 (-105 to 100) kcal after INSTI restart; energy balance (EE-EI) increased by 266 (-126 to 658) kcal from Week 0 to Week 12, and decreased by 3 (-429 to 423) kcal from Week 12 to Week 24. Trends toward weight loss occurred following switch to doravirine [mean -1.25 (-3.18 to 0.69) kg] and when back on INSTI [-0.47 (-2.45 to 1.52) kg]. Trunk fat decreased on doravirine [-474 (-1398 to 449) g], with some regain following INSTI restart [199 (-747 to 1145) g]. Fat-free mass decreased on doravirine [-491 (-1399 to 417) g] and increased slightly after INSTI restart [178 (-753 to 1108) g]. CONCLUSIONS Among PWH with >10% weight gain on an INSTI, switch to doravirine was associated with a trend towards decreases in 24 h EE, weight, trunk fat mass and fat-free mass. Observed changes were not significant, but suggest a mild weight-suppressive effect of doravirine among PWH.

Abstract
Background Switching from non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens to dolutegravir (DTG) has been associated with greater weight gain. Methods We conducted our analysis using a longitudinal cohort of people with HIV (PWH) in Western Kenya. We evaluated changes in the rate of weight gain among treatment-experienced, virally suppressed PWH who switched from NNRTI to tenofovir disoproxil fumarate, lamivudine, and dolutegravir (TLD). We modeled the weights pre- and postswitch using a 2-phase model with linear trend preswitch and an inverted exponential function postswitch. We estimated an 18-month excess weight gain by comparing the projected weight with that expected using the preswitch rate. Results A total of 18 662 individuals were included in our analysis, with 55% switching from efavirenz (EFV) and 45% from nevirapine (NVP). Of the studied individuals, 51% were female, and the median age and body mass index (BMI) were 51 years and 22 kg/m2, respectively. For the overall population, the rate of weight gain increased from 0.47 kg/year preswitch to 0.77 kg/year, with higher increases for females (0.57 kg/year to 0.96 kg/year) than males (0.34 kg/year to 0.62 kg/year). The rate of weight gain for individuals switching from EFV-based regimens significantly increased from 0.57 kg/year preswitch to 1.11 kg/year postswitch but remained stable at 0.35 kg/year preswitch vs 0.32 kg/year postswitch for individuals switching from NVP-based regimens. Conclusions Switching from NNRTI-based regimens to TLD is associated with a modest increase in the rate of weight gain, with the preswitch NNRTI being the key determinant of the amount of weight gain experienced postswitch.

Abstract
Weight changes vary among people living with HIV (PLHIV) on different antiretroviral therapy (ART) regimens. Here, we performed multi-trajectory modeling fitting growth mixture models (GMM) to identify longitudinal weight change trajectories of PLHIV. Multiple logistic regression was used to assess correlates of rapid weight gains; 12,683 PLHIV (median age: 34 years [interquartile range 29-42], 91.1% male) who initiated ART at the Third People's Hospital of Shenzhen, China, between January 2003 and September 2022 were included. We identified two trajectories: slow (70.5%) and rapid weight gains (29.5%). PLHIV who initiated ART with dolutegravir- (adjusted odds ratio [aOR] 2.46, 1.92-3.15), raltegravir- (2.74, 1.96-3.82), and lopinavir (1.62, 1.36-1.94)-based regimens were more likely to have rapid weight gains compared with efavirenz-based regimen. The monitoring of nutritional status should be strengthened for PLHIV who initiated these regimens during regular ART follow-ups.

Abstract
BACKGROUND Research suggests that integrase strand transferase inhibitor use can lead to weight gain, and data from sub-Saharan countries are limited. This study investigated changes in weight in Namibians switched from tenofovir DF/emtricitabine/efavirenz (TEE) to tenofovir DF/lamivudine/dolutegravir (TLD). METHODS Longitudinal, retrospective, and quantitative study from outpatient records of Namibians living with HIV/AIDS switched from efavirenz-to dolutegravir-based regimen at four clinics. A linear mixed effects model predicting weight 6 months prior to the switch, time of the switch, and at 6, 12-, and 18-months post-switch was run. A second analysis comparing change in weights between males and females was also run. RESULTS 242 patients switched from TEE to TLD. Compared to patient weight at the time of the switch, weights were significantly higher at 6 (+0.9 kg, p = 0.004), 12 (+1.7 kg, p < 0.001), and 18 months (+1.4 kg, p < 0.001) post-switch. There was no significant weight change for males, but females had a significant weight gain at 12 (+1.58 kg, p = 0.012) and 18 months (+1.49 kg, p = 0.024) post switch. CONCLUSIONS Females living with HIV in Namibia gain weight when switched from TEE to TLD. Clinical implications on the development of cardiometabolic complications is unclear and mechanisms by which the weight gain occurs are unknown.

Abstract
INTRODUCTION Switch to dolutegravir (DTG) in treatment-experienced people living with HIV (PLH) is associated with excess weight gain in some settings; data are limited from rural low-income settings with low obesity prevalence. METHODS In rural Kenya, we conducted a retrospective cohort study at 8 HIV clinics and a single-site prospective cohort study including adults switching to DTG during countrywide transition to DTG/tenofovir DF(TDF)/emtricitabine as first-line HIV treatment. In the retrospective analysis, we used preswitch data to model postswitch weight trajectory had each participant not switched to DTG and contrasted observed vs. predicted postswitch weight. In the prospective analysis, we measured weight post-DTG switch and evaluated predictors of 6-month weight change. RESULTS Our retrospective cohort included 4445 PLH who switched to DTG between 2018 and 2020. Mean 12-month weight change was 0.6 kg preswitch and 0.8 kg postswitch. Among those on TDF throughout (n = 3374; 83% on efavirenz preswitch), 12-month postswitch weight was 0.7 kg more than predicted for women (95% CI: 0.4, 1.0) and similar among men (0.04 kg; 95% CI -0.3, 0.4). In our prospective cohort (n = 135, 100% female), mean 6-month weight change was +0.4 kg (IQR -1.1, 2.0 kg). Predicted gain varied by baseline food insecurity: +1.1 kg (95% CI: 0.34, 1.87) among food secure, -0.09 kg (95% CI -0.71, 0.54) among moderate insecure, and +0.27 kg (95% CI -0.82, 1.36) among severe insecurity. CONCLUSION In contrast to some reports of large weight gain following switch to DTG, we observed small weight increases in women and no weight change in men following DTG switch when on TDF throughout. Weight gain may be attenuated by food insecurity, though was modest even among food secure.

Abstract
Further investigations into the relationship between integrase strand transfer inhibitors (INSTIs) and weight gain are required, especially whether ceasing INSTI results in weight loss. We evaluated weight changes associated with different antiretroviral (ARV) regimens. A retrospective longitudinal cohort study was conducted using data extracted from the electronic clinical database at the Melbourne Sexual Health Centre, Australia, from 2011 to 2021. The association between weight change per time unit and ARV use in people living with HIV (PLWH) and the factors associated with weight changes when using INSTIs were estimated using a generalized estimated equation model. We included 1540 PLWH contributing 7476 consultations and 4548 person-years of data. ARV-naive PLWH initiating INSTIs gained an average of 2.55 kg/year (95% confidence interval 0.56 to 4.54; p = 0.012), while those using protease inhibitors and non-nucleoside reverse transcriptase inhibitors had no significant weight change. When switching off INSTIs, there was no significant weight change (p = 0.055). These weight changes were adjusted for age, gender, time on ARVs, and/or use of tenofovir alafenamide (TAF). Weight gain was the main reason PLWH ceased INSTIs. In addition, risk factors for weight gain in INSTI users were age younger than 60 years, male gender, and concomitant use of TAF. Weight gain was found among PLWH using INSTIs. After INSTI discontinuation, PLWH's weight stopped rising, but no weight loss was observed. Careful weight measurement after initiating INSTIs and early initiation of strategies to avoid weight gain will be important to prevent permanent weight gain and the associated morbidity.

Abstract
Importance Recent advances in treatment and prevention of HIV warrant updated recommendations to guide optimal practice. Objective Based on a critical evaluation of new data, to provide clinicians with recommendations on use of antiretroviral drugs for the treatment and prevention of HIV, laboratory monitoring, care of people aging with HIV, substance use disorder and HIV, and new challenges in people with HIV, including COVID-19 and monkeypox virus infection. Evidence Review A panel of volunteer expert physician scientists were appointed to update the 2020 consensus recommendations. Relevant evidence in the literature (PubMed and Embase searches, which initially yielded 7891 unique citations, of which 834 were considered relevant) and studies presented at peer-reviewed scientific conferences between January 2020 and October 2022 were considered. Findings Initiation of antiretroviral therapy (ART) is recommended as soon as possible after diagnosis of HIV. Barriers to care should be addressed, including ensuring access to ART and adherence support. Integrase strand transfer inhibitor-containing regimens remain the mainstay of initial therapy. For people who have achieved viral suppression with a daily oral regimen, long-acting injectable therapy with cabotegravir plus rilpivirine given as infrequently as every 2 months is now an option. Weight gain and metabolic complications have been linked to certain antiretroviral medications; novel strategies to ameliorate these complications are needed. Management of comorbidities throughout the life span is increasingly important, because people with HIV are living longer and confronting the health challenges of aging. In addition, management of substance use disorder in people with HIV requires an evidence-based, integrated approach. Options for preexposure prophylaxis include oral medications (tenofovir disoproxil fumarate or tenofovir alafenamide plus emtricitabine) and, for the first time, a long-acting injectable agent, cabotegravir. Recent global health emergencies, like the SARS-CoV-2 pandemic and monkeypox virus outbreak, continue to have a major effect on people with HIV and the delivery of services. To address these and other challenges, an equity-based approach is essential. Conclusions and Relevance Advances in treatment and prevention of HIV continue to improve outcomes, but challenges and opportunities remain.

Abstract
Widespread availability of antiretroviral therapies (ART) for HIV-1 have generated considerable interest in understanding the pharmacogenomics of ART. In some individuals, ART has been associated with excessive weight gain, which disproportionately affects women of African ancestry. The underlying biology of ART-associated weight gain is poorly understood, but some genetic markers which modify weight gain risk have been suggested, with more genetic factors likely remaining undiscovered. To overcome limitations in available sample sizes for genome-wide association studies (GWAS) in people with HIV, we explored whether a multi-ancestry polygenic risk score (PRS) derived from large, publicly available non-HIV GWAS for body mass index (BMI) can achieve high cross-ancestry performance for predicting baseline BMI in diverse, prospective ART clinical trials datasets, and whether that PRSBMI is also associated with change in BMI over 48 weeks on ART. We show that PRSBMI explained ∼5-7% of variability in baseline (pre-ART) BMI, with high performance in both European and African genetic ancestry groups, but that PRSBMI was not associated with change in BMI on ART. This study argues against a shared genetic predisposition for baseline (pre-ART) BMI and ART-associated weight gain.

Abstract
Background Dolutegravir, a component of the preferred first-line antiretroviral therapy regimen, has been associated with increased weight gain. South Africa has a high prevalence of obesity, especially among women. Understanding dolutegravir exposure in patients with obesity is important for dose optimisation. Objectives We compared the pharmacokinetic parameters of dolutegravir in Southern African adults living with HIV with and without obesity. Method Blood samples were collected at various time points over a 24 h-period for dolutegravir assays. Non-compartmental analysis was conducted and geometric mean ratios (GMRs), with 90% confidence intervals (CIs), were generated to compare dolutegravir pharmacokinetic parameters between the groups. Regression analyses to assess predictors of dolutegravir exposure were done. Results Forty participants were enrolled, 26 were women and 10 had obesity. Dolutegravir area under the concentration-time curve to 24-h and the maximum concentrations were not statistically significantly lower in participants with obesity: GMR 0.91 (90% CI: 0.71-1.16) and GMR 0.86 (90% CI: 0.68-1.07), respectively. In a multivariate linear regression analysis adjusting for age, gender, body mass index, creatinine clearance and randomisation arm (tenofovir alafenamide or tenofovir disoproxil fumarate), a unit increase in body mass index was associated with 1.2% lower dolutegravir area under the concentration-time curve to 24-h (P = 0.035). Conclusion Dolutegravir exposure was marginally lower in participants with obesity, but this is not clinically significant. Our findings suggest that there is no need to dose adjust dolutegravir in people with obesity.

Abstract
OBJECTIVE Antiretroviral therapy (ART) extends the life of people with HIV (PWH), but these individuals are at increased risk for obesity, dyslipidemia, diabetes, and cardiovascular disease. These comorbidities may be a consequence of HIV-related chronic inflammation and/or adverse effects of ART on tissue regulatory adipose tissue macrophages (ATMs). We sought to determine the effects of HIV/ART on metabolically beneficial ATM populations and functions. DESIGN We examined subcutaneous ATMs from PWH on integrase inhibitor-containing ART ( n = 5) and uninfected persons ( n = 9). We complemented these studies with ex vivo and in vitro analyses of peripheral blood mononuclear cell (PBMC) and murine macrophage lipid metabolism and fatty acid oxidation gene expression. METHODS ATM populations were examined by flow cytometry. Macrophage lipid metabolism and fatty acid oxidation gene expression were examined by Seahorse assay and quantitative PCR. RESULTS Adipose tissue from PWH had reduced populations of metabolically activated CD9 + ATMs compared to that of uninfected controls ( P < 0.001). PBMCs of PWH had lower fatty acid metabolism compared to those of uninfected controls ( P < 0.01). Analysis of murine macrophages revealed that dolutegravir reduced lipid metabolism ( P < 0.001) and increased expression of the fatty acid beta-oxidation enzyme enoyl-CoA hydratase, short chain 1 ( P < 0.05). CONCLUSIONS We report the loss of metabolically beneficial ATM populations in PWH on ART, altered fatty acid metabolism of blood immune cells, and evidence that dolutegravir alters macrophage fatty acid metabolism. Future studies should examine direct or indirect effects and mechanisms of dolutegravir, and other integrase inhibitors and ART classes, on fatty acid beta-oxidation.

Abstract
ABSTRACT
Background
We determined the frequency of and factors associated with ≥10% weight gain and its metabolic effects in virally suppressed people with HIV (PWH) from the Dutch national ATHENA cohort switching to TAF and/or INSTI.
Methods
We identified ART-experienced, but TAF/INSTI-naïve PWH, who switched to a TAF and/or INSTI-containing regimen whilst virally suppressed for >12 months. Individuals with comorbidities/co-medication associated with weight change were excluded. Analyses were stratified by switch to only TAF, only INSTI or combined TAF + INSTI. Factors associated with ≥10% weight gain were assessed using parametric survival models. Changes in glucose, lipids and blood pressure post-switch were modelled using mixed-effect linear regression and compared between those with and without ≥10% weight gain.
Results
Among 1,544 PWH who switched to only TAF, 2,629 to only INSTI and 918 to combined TAF + INSTI, ≥10% weight gain was observed in 8.8%, 10.6% and 14.4%, respectively. Across these groups, weight gain was more frequent in Western and Sub-Saharan African females than Western males. Weight gain was also more frequent in those with weight loss ≥1 kg/yr before switching, age < 40 years, and those discontinuing efavirenz. In those with ≥10% weight gain, 53.7% remained in the same BMI category, whilst a BMI change from normal/overweight at baseline to obesity at 24 months post-switch was seen in 13.9%, 11.7% and 15.2% of those switching to only TAF, only INSTI and combined TAF + INSTI respectively. PWH with ≥10% weight gain showed significantly larger, but small increases in glucose, blood pressure and lipid levels. Lipid increases were limited to those whose switch included TAF, whereas lipids decreased after switching to only INSTI.
Conclusions
Weight gain of ≥10% after switch to TAF and/or INSTI was common in virally suppressed PWH, particularly in females and those starting both drugs simultaneously. Consequent changes in metabolic parameters were however modest.

Abstract
OBJECTIVE To describe weight changes with integrase strand transfer inhibitor (INSTI) therapy. DATA SOURCES A literature search was performed (through December 15, 2021) using the PubMed and CINAHL databases using the search terms: "integrase inhibitors," "integrase strand transfer inhibitors," and "weight." STUDY SELECTION AND DATA EXTRACTION Studies were included that provided relevant information on weight or body mass index (BMI) changes on INSTI therapy. Controlled or observational studies comparing different INSTI therapies or compared INSTI therapy to another class of antiretroviral therapy were included. DATA SYNTHESIS Forty-three articles met criteria for inclusion, and data are presented. Although some trials have observed similar weight gains between INSTI, protease inhibitor, and non-nucleoside inhibitor therapies, the increase appears to be greater with INSTI therapy, particularly during initiation of therapy. Risk factors for weight gain with INSTI therapy include female gender, lower CD4 count, and combined use of tenofovir alafenamide. Within the INSTI class, dolutegravir and bictegravir appear to have the greatest propensity for weight gain. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE INSTI-based therapies are the preferred initial management of HIV infection. Discerning the factors contributing to weight changes on INSTI therapy and risks of associated health-related outcomes is important to both the management of weight gain and HIV medical management. CONCLUSIONS Within the INSTI class, dolutegravir and bictegravir may be associated with the greatest risk for weight gain particularly when combined with tenofovir alafenamide. Further research is needed to determine mechanisms for observed weight changes and any contributions to clinically significant metabolic and cardiovascular adverse outcomes associated with INSTI therapy.

Abstract
OBJECTIVE This study evaluated body mass index (BMI) and weight changes in people living with human immunodeficiency virus (HIV-1; PLWH) initiated on single-tablet darunavir/cobicistat/emtricitabine/tenofovir alafenamide (DRV/c/FTC/TAF) or bictegravir/FTC/TAF (BIC/FTC/TAF). METHODS Electronic medical record (EMR) data for treatment-naïve or virologically suppressed adults with HIV-1 who initiated treatment with DRV/c/FTC/TAF or BIC/FTC/TAF (index date) were obtained from Decision Resources Group's EMRs (17 July 2017-1 March 2020). Inverse probability of treatment weighting was used to account for differences in baseline characteristics between the two cohorts. BMI and weight changes from pre-index to 3, 6, 9 and 12 months following the index date were compared using weighted mean differences (MDs). The time until an increase in BMI or weight ≥5% or ≥10% was compared using weighted hazard ratios (HRs). RESULTS The weighted DRV/c/FTC/TAF and BIC/FTC/TAF cohorts comprised 1116 and 1134 PLWH, respectively (mean age = ∼49 years, females: ∼28%). Larger increases in BMI and weight from pre-index to each post-index time point were observed in PLWH initiating BIC/FTC/TAF vs DRV/c/FTC/TAF (12 months: MD in BMI = 1.23 kg/m2, p < .001; MD in weight = 2.84 kg [6.26 lbs], p = .008). PLWH receiving BIC/FTC/TAF were significantly more likely to experience weight gain ≥5% (HR = 1.76, p = .004) and ≥10% (HR = 2.01, p = .020), and BMI increase ≥5% (HR = 1.77, p = .004) and ≥10% (HR = 1.76, p = .044) than those receiving DRV/c/FTC/TAF. CONCLUSIONS BIC/FTC/TAF was associated with greater BMI and weight increases compared to DRV/c/FTC/TAF. Weight gain and its sequelae may add to the clinical burden of PLWH and should be considered among other factors when selecting antiretroviral single-tablet regimens.

Abstract
Aim Dolutegravir is associated with more weight gain than efavirenz in people starting antiretroviral therapy (ART). We investigated the concentration-response relationships of efavirenz and dolutegravir with weight gain. Methods We determined concentration-response relationships of dolutegravir and efavirenz (both combined with tenofovir disoproxil fumarate and emtricitabine) with changes in weight and fat distribution, derived from dual-energy x-ray absorptiometry scans, in a nested study of ART-naïve participants from a randomised controlled trial. Pharmacokinetic parameters used in analyses were efavirenz mid-dosing interval (MDI) concentrations and estimated dolutegravir area under the concentration-time curve (AUC0-24) using a population pharmacokinetic model developed in the study population. Study outcomes were percentage changes from baseline to week 48 in weight, and visceral and subcutaneous adipose tissue (VAT and SAT) mass. Results Pharmacokinetic data were available for 158 and 233 participants in the efavirenz arm and dolutegravir arms respectively; 57.0% were women. On multivariable linear regression there were independent negative associations between efavirenz concentrations and changes in both weight (P <0.001) and SAT mass (P = 0.002). Estimated dolutegravir AUC0-24 was not associated with change in weight (P = 0.109) but was negatively associated with change in VAT mass (P = 0.025). Conclusion We found an independent negative concentration-response relationship between efavirenz concentrations and weight change in ART-naïve participants. Dolutegravir concentrations were not independently associated with weight change. These findings suggest that weight gain differences between efavirenz and dolutegravir are driven by efavirenz toxicity impairing weight gain rather than by off-target effects of dolutegravir causing weight gain.

[PMID: 34877366 PMCID: PMC8643706 DOI: 10.1093/ofid/ofab542] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Accepted: 10/28/2021] [Indexed: 12/16/2022] Open
Abstract
Numerous studies have detected a greater likelihood of excess weight gain with specific antiretrovirals (ARVs), particularly tenofovir alafenamide and integrase inhibitors, as compared with other agents and classes. The long-term implications and potential reversibility for individuals who have experienced substantial ARV-associated weight accumulation remain poorly understood. Furthermore, the underlying mechanism remains controversial: Is the explanation mitochondrial toxicity and weight suppression from the older agents or direct effects of the newer drugs on appetite, adipocytes, or other unintended targets? This review discusses proposed mechanisms and evidence to date and argues that the question about mechanism is highly clinically relevant because it carries significant implications for ARV management. The existing literature suggests that older ARVs, such as tenofovir disoproxil fumarate and efavirenz, suppress weight gain, but also that integrase inhibitors may stimulate excess weight gain through several plausible biologic pathways. Confirming the mechanisms of ARV-associated excess weight gain should be high priority for future research.

HIV Med 2021; 23:362-370.

Abstract
OBJECTIVES Tenofovir disoproxil fumarate (TDF) is associated with reduced bone mineral density (BMD). The aim of the study was to evaluate changes in BMD in women who switched from TDF, emtricitabine and a nonnucleoside reverse transcriptase inhibitor (TDF/FTC/NNRTI) to abacavir, lamivudine and dolutegravir (ABC/3TC/DTG). METHODS We conducted a randomized controlled trial in which women aged ≥ 40 years were randomized 1:2 to continue TDF/FTC/NNRTI or switch to ABC/3TC/DTG. We analysed changes in BMD at the hip and lumbar spine from baseline to week 96 using linear regression, and markers of bone turnover and kidney function using repeated measures mixed effects models with multiple imputation for missing data. We conducted exploratory analyses of weight, mental health, sleep and symptoms attributed to HIV infection and antiretroviral therapy. RESULTS Ninety-one women [mean (standard deviation) age 50.4 (6.6) years] were randomized. Women who switched to ABC/3TC/DTG maintained viral suppression and experienced improvements in BMD at the lumbar spine (but not the neck of the femur or the total hip), bone resorption markers and proteinuria (total protein, albumin and retinol-binding protein) and modest weight gain without changes in body mass index. Although mean anxiety, depression and sleep scores did not differ between the two study arms, anxiety, depression and sleep disturbance at baseline predicted ABC/3TC/DTG discontinuation for neuropsychiatric side effects [odds ratios (95% confidence intervals) 11.9 (2.0-71.6), 16.0 (2.6-97.9) and 10.0 (1.8-56.0), respectively]. CONCLUSIONS Switching from TDF/FTC/NNRTI to ABC/3TC/DTG improved the BMD of the lumbar spine and kidney function. These benefits need to be balanced against modest weight gain and the need for antiretroviral therapy substitutions in a proportion of participants.

Abstract
BACKGROUND The late-onset efavirenz neurotoxicity syndrome (LENS) presents as ataxia and/or encephalopathy with supratherapeutic efavirenz plasma concentrations (>4 µg/mL). Efavirenz is primarily metabolized by cytochrome P450 2B6 (CYP2B6), with CYP2A6 as an accessory pathway. We hypothesized that participants with LENS would predominantly be CYP2B6 slow metabolizers. The aim of our study was to determine the frequency of CYP2B6 slow metabolizers in participants with LENS. METHODS Adult HIV-positive participants on efavirenz-based antiretroviral therapy presenting with LENS were prospectively enrolled. Genetic polymorphisms known to be associated with increased efavirenz plasma concentrations in CYP2B6 (rs3745274, rs28399499, rs4803419) and CYP2A6 (rs28399433) were selected and used to determine proportions of slow metabolizers. Pharmacokinetic analyses were performed using liquid chromatography-tandem mass spectrometry. Median (IQR) plasma efavirenz and 8-hydroxyefavirenz were described. RESULTS Fifteen participants were enrolled. Thirteen (13/15) were Black-African and 13 were female. Median weight was 49.9kg with a median duration on efavirenz of 2.2 years. All 15 participants were successfully genotyped as slow CYP2B6 metabolizers, with 6 participants additionally having CYP2A6 heterozygous genotype. Thirteen were receiving the CYP2A6 enzyme inhibitor isoniazid, and all 15 were genotypic NAT2 slow or intermediate acetylators. Efavirenz plasma concentration was markedly increased at 50.5 (47.0-65.4) µg/mL; 8-hydroxyefavirenz concentration was markedly decreased at 0.10 (0.07-0.15) µg/mL. CONCLUSIONS Our cohort provides definitive evidence that LENS is associated with the CYP2B6 slow metabolizer genotype, with a median efavirenz plasma concentration >12-fold higher than the defined upper limit of the therapeutic range. Isoniazid and low body weight are important contributors to LENS development.

Abstract
We report a case of substantial weight gain in a virologically suppressed patient with HIV after changing his antiretroviral therapy from efavirenz/emtricitabine/tenofovir DF to elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide with subsequent rapid weight loss upon switching back. The role of antiretrovirals in weight gain and loss and patient- and HIV-specific factors are discussed.

Abstract
PURPOSE OF REVIEW Obesity is increasing in people with HIV (PWH). This review aims to summarise the recent evidence investigating the associations between the use of integrase inhibitors and tenofovir alafenamide (TAF) with weight gain and the mechanisms by which this may occur. Understanding the role that antiretroviral therapies play in promoting weight gain is critical in making informed treatment decisions. RECENT FINDINGS Weight gain is common with antiretroviral therapies and can lead to significant medical complications for PWH. Antiretroviral regimens containing an integrase inhibitor in conjunction with TAF are associated with the greatest degree of weight gain. This weight gain is greatest with dolutegravir and bictegravir compared with other integrase inhibitors. Some of the measured weight gain attributed to TAF may actually reflect a loss of weight suppressant effects of tenofovir disoproxil fumarate, and thus the exact proportional contribution of TAF remains to be seen. The mechanisms by which advent of antiretroviral therapy may be promoting weight gain is still being determined but underlying genetic risks factors and gender are very important determinants of the degree of weight gained. SUMMARY Integrase inhibitors and TAF contribute to weight gain in PWH. This places them at risk for potentially serious medical complications.

Abstract
BACKGROUND Excessive weight gain affects some HIV-positive individuals prescribed dolutegravir-containing regimens. Mechanisms underlying such weight gain are unknown. SETTING Data and DNA from antiretroviral therapy-naïve participants who were randomized to initiate dolutegravir with emtricitabine plus either tenofovir alafenamide (TAF) or tenofovir disoproxil fumarate (TDF) in the ADVANCE study (NCT03122262) were used to characterize associations between human genetic polymorphisms and magnitude of weight gain. METHODS Associations with percent weight gain from baseline to week 48 were assessed using multivariable linear regression models. Primary analyses a priori considered 59 polymorphisms and 10 genes of potential relevance to dolutegravir, TAF, or TDF pharmacokinetics. We also explored genome-wide associations. RESULTS Among the 314 (92%) of 340 dolutegravir recipients who were successfully genotyped, 160 (47%) and 154 (45%) were randomized to TAF/emtricitabine and TDF/emtricitabine, respectively. In target gene analyses, the lowest P-values for the dolutegravir and tenofovir groups were ABCG2 rs4148149 (P = 7.0 × 10-4) and ABCC10 rs67861980 (P = 1.0 × 10-2), respectively, which were not significant after correction for multiple testing. In genome-wide analyses, the lowest P-values were rs7590091 in TMEM163 (P = 3.7 × 10-8) for dolutegravir, rs17137701 in LOC105379130 (P = 6.4 × 10-8) for TAF, and rs76771105 in LOC105371716 (P = 9.7 × 10-8) for TDF. CONCLUSIONS Among South African participants in a randomized clinical trial of dolutegravir plus either TAF/emtricitabine or TDF/emtricitabine, we identified several potential genetic associations with weight gain. Only TMEM163 rs7590091 withstood correction for multiple testing. These associations warrant replication in other cohorts.

Abstract
BACKGROUND We sought to identify factors associated with weight gain in randomized clinical trials of antiretroviral (ART) switch. METHODS We explored the effects of demographic factors, clinical characteristics, and ART on weight gain in a pooled analysis of 12 prospective clinical trials, wherein virologically-suppressed people with HIV (PWH) were randomized to switch or remain on stable baseline regimen (SBR). RESULTS Both PWH randomized to switch ART (n=4,166) and those remaining on SBR (n=3150) gained weight. Median weight gain was greater in those who switched (1.6 [IQR -.05, 4.0] vs 0.4 [IQR -1.8, 2.4] kg at 48 weeks, p<0.0001), with most weight gain occurring in the first 24 weeks after switch. Among baseline demographic and clinical characteristics, only younger age and lower baseline body mass index were associated with any or ≥10% weight gain. 4.6% gained ≥10% weight by week 48 (6.4% of switch and 2.2% of SBR), the greatest risk with switch from EFV to RPV or EVG/c, and switch from TDF to TAF. Switch from ABC to TAF was associated with less weight gain than switch from TDF to TAF, and was not associated with increased risk for ≥10% weight gain. CONCLUSIONS Moderate weight gain after ART switch was common, and usually plateaued by 48 weeks. Baseline ART was a predictor of post-switch weight gain: participants switching off EFV and TDF had the greatest weight gain. The biological mechanisms underlying the differential effects of switching ART agents on weight and associated clinical implications require further study.

Abstract
There is a growing body of evidence from both observational and randomised trials implicating integrase inhibitors, particularly dolutegravir and bictegravir, with the development of weight gain and obesity in people living with HIV. Evidence with cabotegravir, the newest integrase inhibitor, is limited. Reasons for weight gain are currently unknown. Proposed mechanisms include improved tolerability, direct impact on adipogenesis, and gut microbiome disturbance. Clinical trials have found that weight gain with integrase inhibitors is greatest for women and people of Black ethnicity. Evidence suggests that the nucleoside reverse transcriptase backbone has additional effects on weight gain, with tenofovir alafenamide potentially enhancing the weight gain effect. Weight gain and obesity have long-term consequences, including metabolic syndrome, development of type 2 diabetes mellitus, cardiovascular disease and adverse birth outcomes. However, the current evidence for the medium and long-term effects of weight gain associated with integrase inhibitors is limited. There is an urgent need for clinical trials with longer follow-up periods and standardised endpoints to evaluate these effects. New thresholds for weight gain should be established as guidance for clinicians to stop treatment where weight gain is excessive. Novel treatments such as doravirine could offer a suitable therapy alternative, with current evidence showing efficacy with limited effect on weight gain.

Abstract
Background The predictors of weight gain remain unclear in people with acute and early HIV infection (AEH). Methods Eligible antiretroviral-naïve men diagnosed with AEH from January 1, 2000, to December 31, 2019, were enrolled in an observational cohort study at the University California, San Diego. The study used multivariable mixed-effect linear regression models to analyze differences in the rate of weight gain over time between participants receiving early vs deferred antiretroviral therapy (ART) treatment, low vs high baseline CD4 count and HIV RNA, and different classes of ART. Results A total of 463 participants were identified, with mean CD4 cell count of 507 cells/μL and log HIV RNA of 5.0 copies/mL at study entry. There was no difference in the rate of weight gain between participants who did and did not receive ART within 96 weeks of incident HIV infection. Neither a baseline CD4 count of <350 cells/μL nor a baseline HIV RNA of >100 000 copies/mL was a predictor of weight gain. Compared with persons taking non-nucleoside reverse transcriptase inhibitor-based regimens, those who received integrase strand transfer inhibitor (INSTI)-based regimens showed greater weight gain over time. Conclusions Neither baseline CD4 count and HIV RNA nor early ART was associated with weight change in the first 96 weeks following incident HIV infection. Use of INSTI-based regimens represented a major driver of weight gain in men who initiated ART with relatively higher CD4 cell counts.
