Folic Acid and Methotrexate Use and Their Association with COVID-19 Diagnosis and Mortality: An Analysis from the UK Biobank
Background/Purpose: Folate metabolism is implicated in SARS-CoV-2 infectivity. The current study seeks to determine if methotrexate (an antifolate) or folic acid prescription were associated with…Abstract Number: 1489 • ACR Convergence 2022
Incidence of Herpes Zoster Events After the Three Doses of the BNT162b2 mRNA Vaccine in Patients with Spondyloarthritis
Background/Purpose: The importance and efficacy of anti COVID-19 vaccine in coping with the pandemic are well established, but inconsistencies remain in the data regarding side…Abstract Number: 1857 • ACR Convergence 2022
Increasing Proportion of MDA-5 Associated Conditions in a Tertiary Myositis Centre Following Onset of the Covid-19 Pandemic
Background/Purpose: Anti-MDA5 dermatomyositis is a clinical subtype of DM that is strongly associated with a rapidly progressive phenotype of interstitial lung disease resulting in a…Abstract Number: 2084 • ACR Convergence 2022
COVID-19 Vaccination in Autoimmune Diseases Study: Vaccine Safety in Systemic Lupus Erythematosus
Background/Purpose: The COVID-19 vaccination in autoimmune diseases (COVAD) study is a large-scale real-world survey on COVID-19 vaccine safety in autoimmune rheumatic diseases (AIRDs), including systemic…Abstract Number: L01 • ACR Convergence 2021
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: 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: 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: 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: L09 • ACR Convergence 2021
A Prediction Model to Distinguish Patients with Multisystem Inflammatory Syndrome in Children
Background/Purpose: Multisystem inflammatory syndrome in children (MIS-C) is a rare consequence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). MIS-C shares features with common infectious and…Abstract Number: L16 • ACR Convergence 2021
Breakthrough COVID-19 Infections Post-vaccination Among Immunocompromised Patients with Autoimmune or Inflammatory Rheumatic Diseases: A Retrospective Cohort Analysis from a U.S. Nationally-sampled Electronic Medical Record Data Repository
Background/Purpose: National U.S. data on breakthrough COVID-19 infection in people with autoimmune or inflammatory rheumatic diseases (AIRD) are limited. Our objective was to assess whether breakthrough COVID-19 infections were increased post-COVID-19-vaccination…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: 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: 0074 • ACR Convergence 2021
Association of Anti-phospholipid Antibodies (aPL) with Poor Clinical Outcomes in Hospitalized Patients with COVID-19
Background/Purpose: Critically ill patients with COVID-19 infection have a profound hypercoagulable state and can often develop thromboses in many different vascular beds. Given the presence…
