Background:
This study aimed to identify COVID-19 cases among people living with HIV
(PLWH) in Brazil in 2020, describe their clinical, sociodemographic, and
epidemiological profiles, and evaluate the factors associated with disease
severity.
Methods:
This cross-sectional study used secondary data obtained from the Brazilian
healthcare system. Probabilistic and deterministic data linkage methods were
used to identify coinfected patients. Descriptive statistical analysis was
conducted, and factors associated with severe cases were evaluated using
Pearson's chi-squared test, Student's t-test, and logistic regression.
Results:
In 2020, 36,746 coinfections were identified, making it one of the largest
coinfection databases described worldwide. In total, 4,502 (12.25%) patients
had severe cases and 32,244 (87.75%) had non-severe cases. The covariates
age (OR=1.05; 95% CI: 1.05-1.06), nonwhite ethnicity (OR=1.68; 95% CI:
1.56-1.81), history of AIDS diagnosis (OR=1.17; 95% CI: 1.08-1.28), recent
HIV diagnosis (OR=5.47; 95% CI: 4.25-7.02), absence of antiretroviral
therapy (OR=1.70; 95% CI: 1.57-1.84), CD4+ < 200 (OR=6.41; 95% CI:
5.09-8.08), detectable HIV viral load (OR=2.61; 95% CI: 2.21-3.05), ≥ 1
comorbidity (OR=4.09; 95% CI: 3.79-4.41), and ≥ 4 symptoms were associated
with increased severity.
Conclusions:
Multiple factors were linked to severe COVID-19, including uncontrolled HIV
infection, age > 50 years, comorbidities, and racial disparities. This
study reinforces the importance of maintaining public policies focused on
early HIV diagnosis, access and adherence to treatment, especially for
minority ethnic groups, and focusing on premature aging in PLWH.
