Characteristics and Outcomes of SARS-CoV-2 Infection Among Adults Living With HIV In Delaware:: The Story of a Syndemic During the First 12 Months of the SARS-CoV-2 Pandemic.

OBJECTIVE

To better characterize the intersection of the HIV and SARS-CoV-2 pandemics, including our robust statewide panel of people living with HIV, in the State of Delaware.

METHODS

We conducted a retrospective descriptive case-series that identified people living with HIV ≥ 18 years old co-infected with SARS-CoV-2 from 1 March 2020 through 9 March 2021 who attended our ambulatory HIV program, through review of testing results, electronic medical records and external clinical records.

RESULTS

There were 105 confirmed cases of SARS-CoV-2 infection and 4 attributable deaths from COVID-19 among adult people living with HIV from 1 March 2020 through 9 March 2021. Co-infected patients had very high rates of ART prescription and virologic suppression, with robust CD4 counts. 24/105 (22.9%) SARS-CoV-2 cases were hospitalized due to COVID-19 and had a significant burden of co-morbidities; a vast majority were AIDS-defined. Age, BMI >30 kg/m, cardiovascular disease, chronic kidney disease and cirrhosis were independently associated with hospitalization by logistic regression. Black patients appeared to have lower rates of testing and higher rates of hospitalization. Additionally, those with history of natural immunity to hepatitis B virus exhibited a low rate of hospitalization.

CONCLUSIONS

Our cohort data is the first to capture the experience of patients co-infected with HIV/SARS-CoV-2 in Delaware, demonstrating the risk of long-term immunosuppression and burden of comorbid disease, even in the setting of virologic suppression. Although not reaching statistical significance, we identified high rates of resolved hepatitis B virus infection amongst non-hospitalized co-infected patients and postulate there may be an underlying immunologic mechanism to this hypothesis-generating observation. Our results also highlight the role that healthcare disparities have played during these overlapping pandemics.

POLICY IMPLICATIONS

Pronounced healthcare disparities are known to worsen outcomes in a variety of disease states. From our descriptive data, we suggest continued efforts to address the social determinants of health, especially as they pertain to common chronic comorbid conditions and certain Black communities.
