Immunogenicity of mRNA COVID-19 Vaccines at 4 and 12 Weeks Post Full Vaccination in Patients with Inflammatory Rheumatic Diseases
Background/Purpose: Emerging evidence indicates that immunosuppressive therapies may result in reduced immunogenicity –and presumably reduced efficacy- following vaccination with mRNA COVID-19 vaccines but long-term data…Abstract Number: L17 • ACR Convergence 2021
Additional Heterologous versus Homologous Booster Vaccination in Immunosuppressed Patients Without SARS-CoV-2 Antibody Seroconversion After Primary mRNA Vaccination: A Randomized Controlled Trial
Background/Purpose: Severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2)-induced coronavirus disease 2019 (COVID-19) has led to exponentially rising mortality, particularly in immunosuppressed patients, who inadequately respond to…Abstract Number: L02 • ACR Convergence 2021
COVID-19 Vaccine in Immunosuppressed Adults with Autoimmune Diseases
Background/Purpose: Immunocompromised conditions and/or a history of autoimmune disease were exclusion criteria of the initial SARS-CoV-2 vaccines clinical trials. We assessed the safety and immunogenicity…Abstract Number: L18 • ACR Convergence 2021
Humoral and Cellular Immune Responses to a Second Dose of COVID-19 Vaccine BNT162b2 in People Receiving Methotrexate or Targeted Immunosuppression: A Cohort Study
Background/Purpose: COVID-19 vaccines have robust immunogenicity in the general population. Data on individuals with immune-mediated inflammatory diseases who are taking immunosuppressants remains limited. Our cohort…Abstract Number: L03 • ACR Convergence 2021
COVID-19 Vaccine Antibody Responses in Patients Treated with B-Cell Agents Depend on B-Cell Counts at Time of Vaccine
Background/Purpose: Optimal COVID-19 vaccine responses are necessary to protect against severe infection. Patients with systemic rheumatic diseases (SRD) are at risk for not mounting adequate…Abstract Number: L19 • ACR Convergence 2021
Secukinumab in Giant Cell Arteritis: A Randomized, Parallel-group, Double-blind, Placebo-controlled, Multicenter Phase 2 Trial
Background/Purpose: Little is known about glucocorticoid-sparing agents in giant cell arteritis (GCA) except for IL-6 inhibition. Secukinumab (SEC) has shown significant improvements in the signs…Abstract Number: L04 • ACR Convergence 2021
SARS-CoV-2 Infections Among Vaccinated Individuals with Rheumatic Disease: Results from the COVID-19 Global Rheumatology Alliance Provider Registry
Background/Purpose: While COVID-19 vaccinations are a critical tool to prevent severe infections, poor immunogenicity in immunocompromised people threatens vaccine effectiveness. We analyzed clinical characteristics of…Abstract Number: L20 • ACR Convergence 2021
Efficacy of Emapalumab, an Anti-IFNγ Antibody in Patients with Macrophage Activation Syndrome (MAS) Complicating Systemic Juvenile Idiopathic Arthritis (sJIA) Who Had Failed High-Dose Glucocorticoids (GCs)
Background/Purpose: MAS is a life-threatening complication of rheumatic diseases, occurring most frequently in sJIA. The mainstay of MAS treatment is high dose GCs; however, GCs…Abstract Number: L05 • ACR Convergence 2021
Phase 2 Study Results from a Randomized, Double-blind, Placebo-controlled, Dose-finding Study to Evaluate Efficacy and Safety of Tigulixostat, a Novel Non-purine Selective Xanthine Oxidase Inhibitor, in Gout Patients with Hyperuricemia
Background/Purpose: Gout can be effectively managed by inhibiting synthesis of uric acid. Tigulixostat is a novel non-purine selective xanthine oxidase inhibitor which lowers production of…Abstract Number: L21 • ACR Convergence 2021
Rituximab versus Conventional Therapeutic Strategy for Remission Induction in Eosinophilic Granulomatosis with Polyangiitis: A Double-blind, Randomized, Controlled Trial

Comparative Safety of Gout “Treat-to-target” and “Usual Care” Treatment Strategies on Cardiovascular Outcomes Using Observational Data: Causal Inference Approach
Background/Purpose: Rheumatology societies recommend serum-urate (SU)-driven treat-to-target (TTT) strategies for the management of gout. However, cardiovascular (CV) safety of urate-lowering therapy (ULT) has been questioned.…Abstract Number: L07 • ACR Convergence 2021
