SARS-CoV-2 Serologic Immune Response in Exogenously Immunosuppressed Patients.

BACKGROUND

While it is presumed that immunosuppressed patients, such as solid organ transplant recipients on immunosuppression, are at greater risk from SARS-CoV-2 infection than the general population, the antibody response to infection in this patient population has not been studied.

METHODS

In this report, we follow the anti-SARS-CoV-2 antibody levels in patients with COVID-19 who are undergoing exogenous immunosuppression. Specifically, we studied the antibody response of 3 solid organ transplant recipient patients, 3 patients who take daily inhaled fluticasone, and a patient on etanercept and daily inhaled fluticasone, and compared them to 5 patients not on exogenous immunosuppression.

RESULTS

We found that the solid organ transplant patients on full immunosuppression are at risk of having a delayed antibody response and poor outcome. We did not find evidence that inhaled steroids or etanercept predispose patients to delayed immune response to SARS-CoV-2.

CONCLUSION

The data presented here suggest that solid organ transplant recipients may be good candidates for early targeted intervention against SARS-CoV-2.
