Dolutegravir

Suicide remains a major public health problem, with nearly 1 million deaths per year. The number tends to increase over time and factors leading to suicide suicidal behaviors are complex. However, there is a paucity of evidence on suicidal behaviors and the associated factors among people living with HIV (PLWH) in Indonesia. Therefore, this study aimed to estimate the prevalence and associated factors of suicidal behavior between indigenous and non-indigenous living with HIV who were on Dolutegravir and Efavirenz therapies...

Viral suppression (VS) in children has remained suboptimal compared to that in adults. We evaluated the impact of transitioning children weighing < 20 kg to a pediatric formulation of dolutegravir (pDTG) on VS in Malawi. We analyzed routine retrospective program data from electronic medical record systems pooled across 169 healthcare facilities in Malawi supported by the Elizabeth Glaser Pediatric AIDS Foundation (EGPAF). We included children who weighed < 20 kg and received antiretroviral therapy (ART) between July 2021-June 2022...

Body weight is influenced by an interplay of individual and environmental factors. In people with HIV (PWH), weight is also influenced by disease status with loss accompanying disease progression that is reversed with effective antiretroviral therapy (ART). Weight changes in comparative ART trials differ by regimen, with greater gains observed with the integrase strand transfer inhibitors (INSTIs) dolutegravir and bictegravir, particularly when co-administered with tenofovir alafenamide fumarate (TAF), compared to regimens that include agents such as tenofovir disoproxil fumarate (TDF) that attenuate weight gain...

BACKGROUND: Antiretroviral therapy (ART)-related weight gain is of particular concern in people with HIV (PWH). While weight gain was observed among PWH receiving tenofovir alafenamide (TAF), little is known about the potential reversibility after TAF discontinuation. We evaluated weight and metabolic changes 12 months after TAF discontinuation in the Swiss HIV Cohort Study. METHODS: We included participants who received at least six months of TAF-containing ART between January 2016 and March 2023...

We here present a case providing valuable insights for clinicians who deliver care to patients identifying as transgender or nonbinary. A 30-year-old trans woman presented to sexual health services requesting a routine sexual health screen and was subsequently diagnosed with HIV and syphilis. She started antiretrovirals for HIV (bictegravir/tenoforvir alafenamide/emtricitabine) 12 days later and was treated with benzathine penicillin G. The patient also had a positive tuberculosis (TB) ELIspot blood test result and further investigations proved the presence of active TB in the chest with mediastinal involvement...

OBJECTIVES: To determine the incidence of opportunistic infections (OIs) and the predictive factors for the development of OIs after antiretroviral therapy (ART) initiation among treatment-naïve patients with HIV infection. RESULTS: Of 401 HIV-infected patients, 38 (9.5%) HIV-infected patients developed OIs after initiating ART, with an incidence rate of 25.6/1000 person-years. The median time (IQR) from ART initiation to OI occurrence was 26.5 (14-73) days...

Bone mineral density (BMD) loss in people living with HIV occurs with the initiation of combined antiretroviral therapy (cART), particularly with tenofovir disoproxil fumarate (TDF) containing cART. Switching from TDF to abacavir (ABC) or dolutegravir (DTG) leads to increased BMD. Whether BMD gains are due to cessation of TDF or anabolic effects of ABC or DTG is unclear. We investigated the effects of ABC and DTG on osteoblast lineage cells in vitro and in vivo . Primary human osteoblasts and male C57BL/6 mice were treated with individual antiretrovirals (ARVs) or a combination of ABC/DTG/lamivudine (3TC)...

UNLABELLED: A fixed-dose combination (FDC) of 50 mg dolutegravir and 300 mg lamivudine is indicated for the treatment of HIV-1 infection. This analysis aimed to characterize the population pharmacokinetics (PK) of dolutegravir and lamivudine based on data from a phase 3 study (TANGO) in virologically suppressed adults living with HIV-1 switching to dolutegravir/lamivudine FDC. These analyses included 362 participants who contributed 2,629 dolutegravir and 2,611 lamivudine samples collected over 48 weeks...

BACKGROUND AND OBJECTIVE: Within the UNIVERSAL project (RIA2019PD-2882) we aim to develop a paediatric dolutegravir (DTG)/emtricitabine (FTC or F)/tenofovir alafenamide (TAF) fixed-dose combination. To inform dosing of this study, we undertook a relative bioavailability (RBA) study in healthy volunteers to investigate a potential pharmacokinetic effect when paediatric formulations of DTG and F/TAF are taken together. METHODS: Participants received all of the following treatments as paediatric formulations in randomised order: a single dose of 180/22...

BACKGROUND: Persistent low-level viraemia (PLLV) is a risk factor for virologic failure among people receiving antiretroviral therapy (ART). OBJECTIVES: We assessed the prevalence and predictors of PLLV among individuals receiving Dolutegravir-based ART in southern Nigeria. DESIGN: This retrospective cohort study used routine program data from electronic medical records of persons receiving Dolutegravir-based first-line ART in 154 PEPFAR/USAID-supported health facilities in Akwa Ibom and Cross Rivers states, Nigeria...

OBJECTIVES: We performed an observational, retrospective, cohort study to assess changes in insulin sensitivity after a switch from dolutegravir/lamivudine (DOL/3TC) or bictegravir/emtricitabine/tenofovir alafenamide (BIC/F/TAF) to doravirine/tenofovir disoproxil fumarate/3TC (DOR/TDF/3TC) in virologically suppressed people living with HIV with recent significant weight gain. METHODS: All non-diabetic patients with HIV treated with DOL/3TC or BIC/F/TAF for ≥12 months, with HIV RNA <20 copies/mL, and with a weight increase ≥3 kg in the last year, who underwent a switch to DOR/TDF/3TC were enrolled into the study...

INTRODUCTION: Dolutegravir/lamivudine (DTG/3TC) was first approved by the US Food and Drug Administration in 2019 for the treatment of antiretroviral therapy (ART)-naive people with HIV-1 based on results from the pivotal GEMINI-1/GEMINI-2 trials. Around that time, immediate initiation of treatment upon diagnosis was recommended in the US Department of Health and Human Services guidelines. Here we report results from 126 treatment-naive people with HIV-1 who initiated DTG/3TC as part of a test-and-treat strategy (n = 61) or with high baseline viral loads (HIV-1 RNA ≥ 100,000 copies/ml; n = 16) from the TANDEM study...

INTRODUCTION: Dolutegravir/lamivudine (DTG/3TC) and dolutegravir/rilpivirine (DTG/RPV) are fixed-dose, complete, single-tablet, two-drug regimens (2DRs) indicated for HIV-1. DTG/3TC is approved for antiretroviral therapy (ART)-naive people with HIV-1 and virologically suppressed individuals to replace current ART; DTG/RPV is indicated for virologically suppressed individuals as a switch option. Virologic efficacy and effectiveness of these DTG-based 2DRs have been demonstrated in phase 3 clinical trials and real-world cohorts, primarily from Europe...

BACKGROUND: One month of daily rifapentine + isoniazid (1HP) is an effective, ultrashort option for TB prevention in people with HIV (PWH). However, rifapentine may decrease antiretroviral drug concentrations and increase the risk of virologic failure. ACTG A5372 evaluated the effect of 1HP on the pharmacokinetics of twice daily dolutegravir. METHODS: A5372 was a multicenter, pharmacokinetic study in PWH (≥18 years) already on dolutegravir-containing antiretroviral therapy with HIV RNA < 50 copies/mL...

BACKGROUND: Since 2019, the World Health Organization has recommended dolutegravir-based antiretroviral therapy (ART) as the preferred regimen for HIV management. Large-scale programmatic transitioning to dolutegravir-based ART was subsequently implemented across Africa, often in the absence of recent viral load testing and without access to genotypic resistance testing (GRT) in case of viremia. METHODS: This study assessed for emerging dolutegravir resistance in the routine care Viral Load Cohort North-East Lesotho (VICONEL)...

BACKGROUND: Confirming the efficacy of dolutegravir/lamivudine in clinical practice solidifies recommendations on its use. METHODS: Prospective cohort study (DUALING) in 24 human immunodeficiency virus (HIV) treatment centers in the Netherlands. HIV RNA-suppressed cases were on triple-drug antiretroviral regimens without prior virological failure or resistance and started dolutegravir/lamivudine. Cases were 1:2 matched to controls on triple-drug antiretroviral regimens by the use of dolutegravir-based regimens, age, sex, transmission route, CD4+ T-cell nadir, and HIV RNA zenith...

The introduction of antiretroviral therapy (ART) has significantly prolonged the lifespan of people living with human immunodeficiency virus (PLWH). However, the sustained use of this drug regimen has also been associated with a cluster of metabolic anomalies, including renal toxicity, which can lead to the development of kidney diseases. In this study, we reviewed studies examining kidney disease in PLWH sourced from electronic databases such as PubMed/MEDLINE, Scopus, and Google Scholar, as well as gray literature...

Syphilis is a worldwide chronic systemic sexually transmitted infection caused by the spirochete bacterium Treponema pallidum . Here, we report a 28-year-old homosexual male who presented to the dermatology clinic with a six-month history of asymptomatic persistent skin lesions. A review of systems revealed unintentional weight loss of about 40 kg within one year. Skin examination revealed multiple scaly and non-scaly hyperpigmented macules and patches on the palms and soles. Hair, nail, and mucus membrane examinations were normal...

OBJECTIVES: The in vivo selection of E157Q plus R263K has not been reported in patients treated with coformulated bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF). To the best of our knowledge, we hereby report the first case of high-grade INSTI resistance associated with the presence of these aminoacidic substitutions in a treatment-experienced HIV patient treated with BIC/FTC/TAF. METHODS: Clinical case report and review of the literature. RESULTS: A heavily treatment-experienced patient was switched to BIC/FTC/TAF due to drug-drug interactions after being diagnosed with disseminated Mycobacterium avium-intracellulare disease...

INTRODUCTION: The DOLAM trial revealed that switching from triple antiretroviral therapy (three-drug regimen; 3DR) to dolutegravir plus lamivudine (two-drug regimen; 2DR) was virologically non-inferior to continuing 3DR after 48 weeks of follow-up. Weight increased with 2DR relative to 3DR but it did not impact on metabolic parameters. METHODS: Multiomics plasma profile was performed to gain further insight into whether this therapy switch might affect specific biological pathways...
