Insights
People living with HIV (PLWH) face a nearly twofold increased risk of COVID-19 mortality. Antiretroviral therapy (ART) may reduce adverse outcomes, but further research is needed.
Area of Science:
- Infectious Diseases
- Virology
- Public Health
Background:
- People living with HIV (PLWH) are a vulnerable population.
- Understanding COVID-19 risks in PLWH is crucial for public health strategies.
- The impact of antiretroviral therapy (ART) on COVID-19 outcomes in PLWH requires investigation.
Purpose of the Study:
- To determine if PLWH have a higher risk of mortality and adverse outcomes from COVID-19.
- To assess whether ART influences the risk of severe COVID-19 outcomes in PLWH.
Main Methods:
- A rapid review and meta-analysis were conducted.
- Searched major databases (Embase, Medline, medRxiv, Google Scholar) for relevant studies up to August 26, 2020.
- Included 19 studies in the review, with a meta-analysis of five higher-quality studies.
Main Results:
- PLWH had a significantly higher risk of COVID-19 mortality (HR 1.95, 95% CI: 1.62-2.34) compared to people without HIV.
- Elevated risk of death persisted in hospitalized PLWH (HR 1.60) and across all settings (HR 2.08).
- Tenofovir disoproxil fumarate-based ART regimens showed a potential association with lower adverse COVID-19 outcomes, though confounding factors exist.
Conclusions:
- Emerging evidence indicates a moderately increased risk of COVID-19 mortality for PLWH.
- Further research is warranted on the impact of CD4+ T-cell count, HIV viral load, and specific ART regimens on COVID-19 outcomes.
- Investigating the role of tenofovir disoproxil fumarate in mitigating COVID-19 severity in PLWH is important.
Objective:
To assess whether people living with HIV (PLWH) are at increased risk of coronavirus disease 2019 (COVID-19) mortality or adverse outcomes, and whether antiretroviral therapy (ART) influences this risk.
Design:
Rapid review with meta-analysis and narrative synthesis.
Methods:
We searched databases including Embase, Medline, medRxiv and Google Scholar up to 26 August 2020 for studies describing COVID-19 outcomes in PLWH and conducted a meta-analysis of higher quality studies.
Results:
We identified 1908 studies and included 19 in the review. In a meta-analysis of five studies, PLWH had a higher risk of COVID-19 mortality [hazard ratio 1.95, 95% confidence interval (CI): 1.62-2.34] compared with people without HIV. Risk of death remained elevated for PLWH in a subgroup analysis of hospitalized cohorts (hazard ratio 1.60, 95% CI: 1.12-2.27) and studies of PLWH across all settings (hazard ratio 2.08, 95% CI: 1.69-2.56). Eight other studies assessed the association between HIV and COVID-19 outcomes, but provided inconclusive, lower quality evidence due to potential confounding and selection bias. There were insufficient data on the effect of CD4+ T-cell count and HIV viral load on COVID-19 outcomes. Eleven studies reported COVID-19 outcomes by ART-regimen. In the two largest studies, tenofovir disoproxil fumarate-based regimens were associated with a lower risk of adverse COVID-19 outcomes, although these analyses are susceptible to confounding by co-morbidities.
Conclusion:
Emerging evidence suggests a moderately increased risk of COVID-19 mortality among PLWH. Further investigation into the relationship between COVID-19 outcomes and CD4+ T-cell count, HIV viral load, ART and the use of tenofovir disoproxil fumarate is warranted.
