What we talk about when we talk about durable viral suppression

'ARVs are a constant reminder of lost freedom, whereas for others, they are liberating': understanding the treatment narrative among people living with HIV (PLHIV) in Malawi and Zimbabwe-a qualitative study

OBJECTIVE

The aim of the research was to understand what drives and motivates young women living with HIV in their treatment journeys, as well as their key influencers. The findings will assist in appreciating their obstacles to treatment and constructing the most effective ways to convey fresh messages to them. These insights will contribute to the messaging developed for a campaign across sub-Saharan Africa, primarily Malawi and Zimbabwe.

DESIGN

This was a qualitative study conducted in order to build an understanding of unknown parts of the HIV treatment journey through in-depth interviews. A hybrid approach was used to conduct thematic analysis.

SETTING AND PARTICIPANTS

Study participants were HIV-positive women, their influencers (eg, parents/partners/siblings/aunts and uncles/religious leaders, etc) and healthcare providers from a range of regions in Zimbabwe and Malawi.

RESULTS

A total of 26 young people living with HIV (PLHIV), 29 healthcare providers and 24 influencers such as maternal figures in the community were interviewed. Two main broad insights were drawn, that is, key needs and wider contextual factors. The key needs of young PLHIV to stay on treatment were empathy, support and emotional connection with antiretroviral therapy (ART), while the wider contextual factors impacting their treatment journeys were structural challenges and cultural reference points. Fear of shame and humiliation can also be significant barriers to disclosure and treatment. The fear predisposes the PLHIV to the need for empathy, support and connection with ART. Mental health and anxiety appear to be comorbid with HIV. Some PLHIV have a small and limited support network leading to very few people living openly with HIV. There is no 'one-size-fits-all' approach, and maximising campaign reach will likely need a multifaceted approach.

CONCLUSION

Currently, the relationship between nurses and PLHIV can appear to be transactional. Through learning about the community (including PLHIV), there are more chances of communicating in a way that resonates.

Durable viral suppression among persons with HIV in the deep south: an observational study

This study assessed predictors of stable HIV viral suppression in a racially diverse sample of persons living with HIV (PWH) in the southern US. A total of 700 PWH were recruited from one of four HIV clinics in Metro Atlanta, GA. Data were collected from September 2012 to July 2017, and HIV viral loads were retrieved from EMR for 18 months. The baseline visits and EMR data were used for current analyses. Durable viral suppression was categorized as 1. Remain suppressed, 2. Remain unsuppressed, and 3. Unstable suppression. The number of antiretroviral medications and age were significantly associated with durable viral suppression. Older age, fewer ART medications and availability of social support were positively associated with durable viral suppression over the 18-month observation period. Findings suggest that regimen complexity is potentially a better predictor of viral suppression than self-reported medication adherence. The need for consensus on the definition of durable viral suppression is also urged.

Intersectionality-informed analysis of durable viral suppression disparities in people with HIV

OBJECTIVE

The aim of this study was to examine drivers of durable viral suppression (DVS) disparities among people with HIV (PWH) using quantitative intersectional approaches.

DESIGN

A retrospective cohort analysis from electronic health records informed by intersectionality to better capture the concept of interlocking and interacting systems of oppression.

METHODS

We analyzed data of PWH seen at a LGBTQ federally qualified health center in Chicago (2012-2019) with at least three viral loads. We identified PWH who achieved DVS using latent trajectory analysis and examined disparities using three intersectional approaches: Adding interactions, latent class analysis (LCA), and qualitative comparative analysis (QCA). Findings were compared with main effects only regression.

RESULTS

Among 5967 PWH, 90% showed viral trajectories consistent with DVS. Main effects regression showed that substance use [odds ratio (OR) 0.56, 0.46-0.68] and socioeconomic status like being unhoused (OR: 0.39, 0.29-0.53), but not sexual orientation or gender identity (SOGI) were associated with DVS. Adding interactions, we found that race and ethnicity modified the association between insurance and DVS ( P for interaction <0.05). With LCA, we uncovered four social position categories influenced by SOGI with varying rates of DVS. For example, the transgender women-majority class had worse DVS rates versus the class of mostly nonpoor white cisgender gay men (82 vs. 95%). QCA showed that combinations, rather than single factors alone, were important for achieving DVS. Combinations vary with marginalized populations (e.g. black gay/lesbian transgender women) having distinct sufficient combinations compared with historically privileged groups (e.g. white cisgender gay men).

CONCLUSION

Social factors likely interact to produce DVS disparities. Intersectionality-informed analysis uncover nuance that can inform solutions.

Virologic outcomes among adults with HIV using integrase inhibitor-based antiretroviral therapy

BACKGROUND

Integrase strand transfer inhibitor (InSTI)-based regimens have been recommended as first-line antiretroviral therapy (ART) for adults with HIV. But data on long-term effects of InSTI-based regimens on virologic outcomes remain limited. Here we examined whether InSTI improved long-term virologic outcomes compared with efavirenz (EFV).

METHODS

We included adults from the North American AIDS Cohort Collaboration on Research and Design who initiated their first ART regimen containing either InSTI or EFV between 2009 and 2016. We estimated differences in the proportion virologically suppressed up to 7 years of follow-up in observational intention-to-treat and per-protocol analyses.

RESULTS

Of 15 318 participants, 5519 (36%) initiated an InSTI-based regimen and 9799 (64%) initiated the EFV-based regimen. In observational intention-to-treat analysis, 81.3% of patients in the InSTI group and 67.3% in the EFV group experienced virologic suppression at 3 months after ART initiation, corresponding to a difference of 14.0% (95% CI 12.4-15.6). At 1 year after ART initiation, the proportion virologically suppressed was 89.5% in the InSTI group and 90.2% in the EFV group, corresponding to a difference of -0.7% (95% CI -2.1 to 0.8). At 7 years, the proportion virologically suppressed was 94.5% in the InSTI group and 92.5% in the EFV group, corresponding to a difference of 2.0% (95% CI -7.3 to 11.3). The observational per-protocol results were similar to intention-to-treat analyses.

CONCLUSIONS

Although InSTI-based initial ART regimens had more rapid virologic response than EFV-based regimens, the long-term virologic effect was similar. Our findings may inform guidelines regarding preferred initial regimens for HIV treatment.

Medicaid Expansion's Impact on Human Immunodeficiency Virus Outcomes in a Nonurban Southeastern Ryan White HIV/AIDS Program Clinic

Background

Although the Ryan White HIV/AIDS Program supports high-quality human immunodeficiency virus (HIV) care, Medicaid enrollment provides access to non-HIV care. People with HIV (PWH) with Medicaid historically have low viral suppression (VS) rates. In a state with previously high Qualified Health Plan coverage of PWH, we examined HIV outcomes by insurance status during the first year of Medicaid expansion (ME).

Methods

Participants were PWH ages 18–63 who attended ≥1 HIV medical visit/year in 2018 and 2019. We estimated associations of sociodemographic characteristics with ME enrollment prevalence and associations between insurance status and engagement in care and VS.

Results

Among 577 patients, 151 (33%) were newly eligible for Medicaid, and 77 (51%) enrolled. Medicaid enrollment was higher for those with incomes <100% federal poverty level (adjusted prevalence ratio, 1.67; 95% confidence interval [CI], 1.00–1.86) compared with others. Controlling for age, income, and 2018 engagement, those with employment-based private insurance (adjusted risk difference [aRD], −8.5%; 95% CI, −16.9 to 0.1) and Medicare (aRD, −12.5%; 95% CI, −21.2 to −3.0) had lower 2019 engagement than others. For those with VS data (n = 548), after controlling for age and baseline VS, those with Medicaid (aRD, −4.0%; 95% CI, −10.3 to 0.3) and with Medicaid due to ME (aRD, −6.2%; 95% CI, −14.1 to −0.8) were less likely to achieve VS compared with others.

Conclusions

Given that PWH who newly enrolled in Medicaid had high engagement in care, the finding of lower VS is notable. The discordance may be due to medication access gaps associated with changes in medication procurement logistics.
