Insights
People with HIV (PWH) face similar COVID-19 severity and hospitalization risks as those without HIV overall. However, PWH with low CD4 counts experienced worse outcomes, while those with high counts showed better or similar hospitalization rates.
Area of Science:
- Infectious Diseases
- Immunology
- Public Health
Background:
- People with HIV (PWH) may be at increased risk for severe COVID-19.
- Understanding COVID-19 outcomes in PWH is crucial for public health strategies.
Purpose of the Study:
- To compare the risk of severe COVID-19 outcomes in PWH versus matched individuals without HIV.
- To investigate the impact of CD4 T-cell counts on COVID-19 severity in PWH.
Main Methods:
- Retrospective cohort study of adults with SARS-CoV-2 in Massachusetts (March 2020-July 2022).
- Used electronic medical record data from three large clinical practice groups.
- Propensity score matching (20:1) to compare outcomes between PWH and individuals without HIV, including severe COVID-19, hospitalization, and length of stay.
Main Results:
- A total of 171,058 individuals with COVID-19 were identified; 768 PWH were matched with 15,360 individuals without HIV.
- Overall severe COVID-19 and hospitalization rates were similar between PWH and controls.
- PWH with low CD4 T-cell counts (<200 cells/mm³) had significantly higher odds of severe COVID-19 and hospitalization (ORs 3.99 and 2.26, respectively).
- PWH with high CD4 counts showed lower odds of hospitalization (OR 0.73).
Conclusions:
- PWH with low CD4 T-cell counts experienced worse COVID-19 outcomes.
- PWH with high CD4 counts had similar or better hospitalization outcomes compared to those without HIV.
- Generalizability to healthcare settings with less PWH access and engagement requires further investigation.
Background:
People with HIV (PWH) may be at risk for more severe COVID-19 outcomes. We compared risk for severe COVID-19 in PWH with matched individuals without HIV.
Methods:
We identified adults in Massachusetts with a positive SARS-CoV-2 test, March 2020-July 2022, using electronic medical record data from 3 large clinical practice groups. We then used regression models to compare outcomes among PWH versus propensity score-matched people without HIV (matched 20:1) for severe COVID-19 (pneumonia or acute respiratory distress syndrome), hospitalization, and hospital length of stay.
Results:
We identified 171,058 individuals with COVID-19; among them, 768 PWH were matched to 15,360 individuals without HIV. Overall, severe COVID-19 and hospitalization were similar in PWH and those without HIV (severe COVID-19: 3.8% vs 3.0%, adjusted odds ratio [OR] 1.27, 95% confidence interval [CI]: 0.86-1.87; hospitalization: 12.1% vs 11.3%, adjusted OR: 1.08, 95% CI: 0.87 to 1.35). Compared with people without HIV, PWH with low CD4 T-cell counts (<200 cells/mm 3 ) had more severe COVID-19 (adjusted OR: 3.99, 95% CI: 2.06 to 7.74) and hospitalization (adjusted OR: 2.26, 95% CI: 1.35 to 3.80), but PWH with high CD4 counts had lower odds of hospitalization (adjusted OR: 0.73, 95% CI: 0.52 to 1.03).
Conclusions:
PWH with low CD4 T-cell counts had worse COVID-19 outcomes compared with people without HIV, but outcomes for those with high CD4 counts were similar to, or better than, those without HIV. It is unclear whether these findings are generalizable to settings where PWH have less access to and engagement with health care.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
