BACKGROUND: In patients with immune-mediated rheumatic diseases (RMD), the development of T-cell responses against SARS-CoV-2 may be impaired by either the immune disturbances associated with the disease, or by the effects of immunosuppressive therapies. We aimed at determining the magnitude of SARS-CoV-2-specific interferon (IFN)-γ-producing T-cell response after COVID-19 recovery in a cohort of patients with RMD on different immunosuppressive therapies.
PATIENTS AND METHODS: 53 adult patients with inflammatory or autoimmune RMD and 61 sex and age-matched non-RMD patients with confirmed COVID-19 were included. Peripheral blood mononuclear cells were obtained and T-cell-IFN-γ antigen-specific responses against the S1 domain of the spike glycoprotein, the nucleoprotein (N) and the membrane (M) protein from SARS-CoV-2 were assessed by FluoroSpot assay.
RESULTS: Patients with RMD and COVID-19 showed positive T-cells-IFN-γ responses to SARS-COV-2 antigens, in a similar proportion and magnitude as non-RMD patients at a median of 298 [151-316] and 165 [162-167] days after COVID-19 respectively. Among RMD patients 83%, 87% and 90%, and among non-RMD patients, 95%, 87% and 93% responded to S1, N and M protein respectively. Similar responses were observed in the different diagnostic and therapeutic groups, including conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs), TNF-α inhibitors, IL-17 inhibitors, rituximab, JAK inhibitors or other immunosuppressants.
CONCLUSION: T-cell responses to the main SARS-CoV-2 antigens are present after COVID-19 recovery in most patients with RMD and are not impaired by immunosuppressive therapies.
