Food Insecurity During the COVID-19 Pandemic: A Longitudinal Mixed-Methods Study from a Cohort of HIV Clients in Uganda

The association between adherence to antiretroviral therapy and viral suppression under dolutegravir-based regimens: an observational cohort study from Uganda

INTRODUCTION

Millions of people living with HIV (PLWH) take oral antiretroviral therapy (ART), which requires a lifetime of consistent medication adherence. The relationship between adherence and poor HIV outcomes is well documented. Newer ART regimens that include dolutegravir (DTG) could be more forgiving, but empirical evidence on the relationship between adherence and viral suppression under DTG is only emerging.

METHODS

In this observational cohort study (secondary analysis of data from a randomized trial), we used data from 313 ART clients from a large HIV clinic in Kampala, Uganda. Over the 4-year study period (January 2018-January 2022), 91% switched from non-DTG regimens to DTG regimens. We measured adherence using Medication Event Monitoring Systems-caps and extracted prescription information and viral load measures from electronic health records. We estimated unadjusted linear regressions and adjusted models that included individual and time fixed-effects.

RESULTS

Under non-DTG regimens, 96% of participants were virally suppressed (defined as viral load < 200 copies/ml) when adherence was 90% or higher in the 3 months before viral load measurement. Viral suppression was 32 percentage points lower when adherence was between 0% and 49% (95% CI -0.44, -0.20, p < 0.01), 12 percentage points lower when adherence was between 50% and 79% (95% CI -0.23, -0.02, p < 0.01), and not significantly different when adherence was between 80% and 89% (effect of 0.00, 95% CI -0.06, 0.07, p = 0.81). In contrast, for participants taking DTG, there was no statistically significant difference in viral suppression among any of the four adherence levels; more than 95% were virally suppressed at each adherence level. On average, switching to DTG increased viral suppression by 6 percentage points in our adjusted models (95% CI 0.00, 0.13, p = 0.03).

CONCLUSIONS

There was no significant association between adherence levels and viral suppression among PLWH taking DTG regimens, suggesting a high degree of forgiveness for missed doses. The use of DTG should be prioritized over older regimens, particularly for those with low adherence.

Impact of COVID-19 on people living with HIV and HIV care: A qualitative study in the Volta Region of Ghana

The COVID-19 pandemic caused significant social changes and challenges globally, including economic slowdown and limitation of essential services. Our study explored the impact of the COVID-19 pandemic on the HIV treatment experiences and lives of people living with HIV in Ghana. Between October 2021 and January 2022, we conducted four focus group discussions with 24 people living with HIV and six in-depth interviews with healthcare providers to understand the impact of the COVID-19 epidemic on their lives and HIV treatment and care. Transcribed interviews were analyzed using thematic analysis. The COVID-19 pandemic most impacted people living with HIV economically and psychosocially. Economic challenges included loss of income/economic support, financial hardship, and material insecurities. The psychosocial impact included fear of the health impact of COVID-19 on people living with HIV and social isolation. The pandemic also impacted participants' HIV treatment and care services including change in their site of care and non-adherence to antiretroviral therapy. Clinics in particular modified HIV care services to maintain treatment and care during the pandemic. Healthcare providers also implemented direct antiretroviral therapy service delivery to clients, which reduced patient overcrowding but increased providers' workload and expenses. The COVID-19 pandemic caused economic hardship, social isolation, and changes in HIV treatment and care services for people living with HIV. It also imposed a work and financial burden on healthcare providers. However, service changes made by providers helped sustain HIV care and treatment for clients and should inform future pandemic responses in HIV services.
