Background Drug resistance testing aids in appropriate antiretroviral therapy selection to improve treatment success but may not be readily available. We evaluated the impact of switching to dolutegravir/lamivudine (DTG/3TC) using pooled data from the TANGO and SALSA trials in adults who were virologically suppressed with or without historical resistance results at screening. Methods Adults who were virologically suppressed (HIV-1 RNA <50 copies/mL for >6 months) with no prior virologic failure were randomized to switch to DTG/3TC (TANGO, n = 369; SALSA, n = 246) or continue their current antiretroviral regimen (CAR; TANGO, n = 372; SALSA, n = 247). Week 48 HIV-1 RNA ≥50 and <50 copies/mL (Snapshot algorithm, Food and Drug Administration; intention-to-treat exposed), CD4+ cell count, and safety were analyzed by availability of historical resistance results. Results Overall, 294 of 615 (48%) participants in the DTG/3TC group and 277 of 619 (45%) participants in the CAR group had no historical resistance results at screening. At week 48, proportions with Snapshot HIV-1 RNA ≥50 copies/mL were low (≤1.1%) and similar across treatment groups and by historical resistance results availability. High proportions (91%–95%) maintained virologic suppression through week 48, regardless of results availability. Across both subgroups of results availability, greater increases in CD4+ cell count from baseline to week 48 occurred with DTG/3TC vs CAR. No participants taking DTG/3TC had confirmed virologic withdrawal, regardless of historical resistance results availability. One participant undergoing CAR without historical resistance results had confirmed virologic withdrawal; no resistance was detected. Overall, DTG/3TC was well tolerated; few adverse events led to withdrawal. Conclusions Findings support DTG/3TC as a robust switch option for adults who are virologically suppressed with HIV-1 and no prior virologic failure, regardless of historical resistance results availability. Clinical trial registration TANGO: NCT03446573, https://clinicaltrials.gov/study/NCT03446573. SALSA: NCT04021290, https://clinicaltrials.gov/study/NCT04021290 [ABSTRACT FROM AUTHOR]

Background To investigate the impact of the M184V/I mutation on virologic response to dolutegravir plus lamivudine (DTG + 3TC) in suppressed-switch populations, a meta-analysis was performed using virologic outcomes from people with human immunodeficiency virus type 1 (PWH) with and without M184V/I before DTG + 3TC switch in real-world studies identified via systematic literature review. Sensitivity analyses were performed using data from PWH with M184V/I in interventional studies identified via targeted literature review. Methods Single-arm meta-analyses using common- and random-effects models were used to estimate proportions of PWH with virologic failure (VF) among real-world populations with and without M184V/I and interventional study participants with M184V/I at 24, 48, and 96 weeks. Results Literature reviews identified 5 real-world studies from 3907 publications and 51 abstracts meeting inclusion criteria and 5 interventional studies from 1789 publications and 3 abstracts. All time points had low VF incidence in PWH with M184V/I (real-world: 1.43%–3.81%; interventional: 0.00%) and without (real-world: 0.73%–2.37%). Meta-analysis–estimated proportions (95% confidence interval) with VF were low at weeks 24, 48, and 96, respectively, for PWH with M184V/I (real-world: 0.01 [.00–.04], 0.03 [.01–.06], and 0.04 [.01–.07]; interventional: 0.00 [.00–.02], 0.00 [.00–.01], and 0.00 [.00–.03]) and without (real-world: 0.00 [.00–.02], 0.02 [.01–.04], and 0.02 [.00–.05]). One real-world study (n = 712) reported treatment-emergent M184V at VF in 1 of 652 (0.15%) PWH without prior M184V/I. Conclusions Results suggest that prior M184V/I has minimal impact on virologic suppression after switching to DTG + 3TC and provide reassurance when considering switching regimens in virologically suppressed PWH with incomplete treatment history or limited treatment options.

We quantified treatment challenges faced by people living with HIV (PLHIV) in Russia. Cross-sectional data of 150 PLHIV in Russia were from the 2019 Positive Perspectives Survey. Mean age was 38.3 y. Two-thirds (68.0%[102/150]) had ever disguised their HIV pills, and 43.3%[65/150] said they would be stressed if someone saw their HIV pills. Overall, 14.7%[22/150] reported being ever diagnosed with substance use disorder (SUD). Self-rated optimal health was significantly lower among those with vs without a report of SUD on multiple health domains: sexual (40.9%[9/22] vs. 70.3%[90/128], p = 0.007), physical (22.7%[5/22] vs. 68.0%[87/128], p < 0.001), and overall health (27.3%[6/22] vs. 68.8%[88/128], p < 0.001). Those reporting SUD were more likely to miss HIV medication ≥ 1 time in the past month because they used recreational drugs (age and gender-adjusted prevalence ratio [APR] = 8.23, 95%CI = 6.99-9.68), could not afford their medication (APR = 3.28, 95%CI = 2.90-3.72), had to work (APR = 3.27, 95%CI = 2.97-3.60), or to avoid side effects (APR = 2.62, 95%CI = 2.37-2.89). Furthermore, self-reported SUD was strongly associated with numerous poor health conditions, including self-reported diagnosis of cancer (APR = 6.67, 95%CI = 5.24-8.48), mental illness (APR = 5.01, 95%CI = 4.53-5.55), and liver disease (APR = 4.29, 95%CI = 3.98-4.61). The distinct patterns of poorer health-related outcomes among PLHIV with SUD underscore the need to address behavioral and psychosocial challenges as part of holistic HIV care.

INTRODUCTION While studies have extensively examined the clinical and pharmacokinetic correlates of drug-drug interactions (DDIs) with antiretroviral therapy (ART), less is known about DDIs from the perspective of people living with HIV (PLHIV). Among an international sample of PLHIV, we examined experiences, concerns and challenges regarding DDIs. METHODS Data came from an international, web-based survey that was conducted among adult PLHIV aged =18 years who were receiving ART during 2019 (Positive Perspectives Wave 2, n=2389). Data were analyzed using descriptive statistics and with a special focus on the Asian region comprising participants from China, Taiwan, Japan, and South Korea (n=230). Multivariable analyses were performed using pooled data from all 2389 participants. Statistical significance was at p<0.05. RESULTS Overall, 59.1% (136/230) of Asian participants were concerned about the risk of DDIs, 58.3% (134/230) were concerned about having to take more medicines as they grew older, and 25.9% (44/170) of those who had ever switched ART attributed it to DDIs, higher than every other geographical region except North America. Among Asian participants, 86.0% (43/50) of those aged =50 years reported having ever been diagnosed with a non-HIV comorbidity versus 60.0% (108/180) aged <50 years (p=0.001). Within the pooled sample, adults aged =50 years were more likely to perceive the need to reduce DDIs as a current treatment priority, than younger adults (adjusted prevalence ratio, APR=1.14; 95% CI: 1.02-1.27). The percentage of the entire population that ever switched ART because of DDIs ranged from 10.6% (148/1402) among those receiving treatment for HIV only, to 26.4% (14/53) among those receiving treatment for =7 conditions (including HIV). CONCLUSIONS Older adults reported more comorbidities than younger ones, and the probability of having switched ART because of DDIs increased with increasing concurrent treatments. Providing simpler regimens may help reduce the risk of DDIs. Healthcare providers can improve PLHIV's health-related quality of life by delivering person-centered care. [ABSTRACT FROM AUTHOR]

Objective(s): To determine the availability and affordability of asthma and COPD medicines across Nigeria. Methods: This was a cross‐sectional survey conducted in 128 pharmacies (51 in public sector hospitals, 51 private sector community pharmacies and 26 charity or big private hospitals) across the six geopolitical zones of Nigeria using the WHO/Health Action Initiative method. The proportion of pharmacies where medicines were available, the median retail prices of originator and generics and affordability were analysed. A medicine was available if found in ≥ 80% of surveyed pharmacies. Unaffordability was defined as paying> 1 day's wage (> US$1.68) for a standard 30‐day supply of the medicine. Results: The available medicines were oral corticosteroids and oral salbutamol which are not on the WHO Essential Medicine List. Medicines were found more frequently in private than public pharmacies and in the southern than northern zones. Inhalable corticosteroid was not available at any public pharmacy nationwide. None of the EML medicines were affordable. The least number of days' wages for a 30‐day supply of any inhalable corticosteroid‐containing medication was 3.5 days. Conclusions: There are very limited availability and affordability of recommended asthma and COPD medicines across Nigeria with disparity across regions. Medicines that were available and affordable are not recommended and are harmful for long‐term use. This underpins the need for engagement of all stakeholders for the review of existing policies regarding access to asthma and COPD medicines to improve availability and affordability.

Objectives: 'Undetectable equals Untransmittable' (U=U) is an empowering message that may enable people living with HIV (PLHIV) to reach and maintain undetectability. We estimated the percentage of PLHIV who ever discussed U=U with their main HIV care provider, and measured associations with health-related outcomes. Secondarily, we evaluated whether the impact of the U=U message varied between those who heard it from their healthcare provider (HCP) vs from elsewhere.Methods: Data were from the 25-country 2019 Positive Perspectives Survey of PLHIV on treatment (n=2389). PLHIV were classified as having discussed U=U with their HCP if they indicated that their HCP had ever told them about U=U. Those who had not discussed U=U with their HCP but were nonetheless aware that 'My HIV medication prevents me from passing on HIV to others' were classified as being made aware of U=U from non-HCP sources. Multivariable logistic regression was used to measure associations between exposure to U=U messages and health outcomes.Results: Overall, 66.5% reported ever discussing U=U with their HCP, from 38.0% (South Korea) to 87.3% (Switzerland). Prevalence was lowest among heterosexual men (57.6%) and PLHIV in Asia (51.3%). Compared with those unaware of U=U, those reporting U=U discussions with their HCP had lower odds of suboptimal adherence (AOR=0.59, 95% CI 0.44 to 0.78) and higher odds of self-reported viral suppression (AOR=2.34, 95% CI 1.72 to 3.20), optimal sexual health (AOR=1.48, 95% CI 1.14 to 1.92) and reporting they 'always shared' their HIV status (AOR=2.99, 95% CI 1.42 to 6.28). While exposure to U=U information from non-HCP sources was beneficial too, the observed associations were attenuated relative to those seen with reported discussions with HCPs.Conclusion: HCP discussion of U=U with PLHIV was associated with favourable health outcomes. However, missed opportunities exist since a third of PLHIV reported not having any U=U discussion with their HCP. U=U discussions with PLHIV should be considered as a standard of care in clinical guidelines. [ABSTRACT FROM AUTHOR]
