In a Macaque Model of RA By Immunization with Citrullinated Peptides, the Valine in the 11 Position of the DRB1 Molecule Has Greater Impacts on T-Cell Response to Citrullinated Peptides Than the 70-74 Position in the Shared Epitope
Background/Purpose: Among genetic risk factors of RA, HLA class II molecules confers the highest risk of ACPA positive RA. The shared epitope (SE) hypothesis that…Abstract Number: 1826 • 2018 ACR/ARHP Annual Meeting
From Cancer to Autoimmunity : A New Model of Rheumatoid Arthritis Emerging from a Constitutional Genetic Approach Used in Low Penetrance Cancers
Background/Purpose: High-speed technologies for genome sequencing have completely changed the study of disease genetics, but with limited knowledge of the functional value of most genetic…Abstract Number: 67 • 2018 ACR/ARHP Annual Meeting
Intestinal Inflammation and Netosis Associate with the Presence of Stool IgA ACPA in Subjects at-Risk for RA
Background/Purpose: Anti-citrullinated protein antibodies (ACPA) and inflammation characterized by neutrophil extracellular trap (NET)osis have been detected at mucosal sites such as the lung and periodontium…Abstract Number: 1976 • 2018 ACR/ARHP Annual Meeting
Sequencing of the MHC Region Defines HLA-DQA1 As Driven Risk for Anti-Citrullinated Protein Antibodies (ACPA)-Positive Rheumatoid Arthritis in Han Population
Background/Purpose: The strong genetic contribution of the major histocompatibility complex (MHC) to rheumatoid arthritis (RA) susceptibility has been generally attributed to HLA-DRB1. However, due to…Abstract Number: 72 • 2018 ACR/ARHP Annual Meeting
Altered Serologic Responses to Epstein Barr Virus Precede Clinical Disease Development in Rheumatoid Arthritis
Background/Purpose: EBV infects B cells and is associated with several autoimmune diseases, including RA. Prior studies have shown that patients with active classified RA…Abstract Number: 2045 • 2018 ACR/ARHP Annual Meeting
Specific Anti-Citrullinated Protein Antibodies Profiles Are Associated with Rheumatoid Arthritis Related Interstitial Lung Disease
Background/Purpose: The identification of peripheral blood markers of rheumatoid arthritis-associated interstitial lung disease (RA-ILD) may facilitate an earlier diagnosis and provide insight regarding the pathogenesis…Abstract Number: 410 • 2017 ACR/ARHP Annual Meeting
Association between Anti-Citrullinated Protein Antibody Status and the Incidence of Erosive Disease in Patients with RA
Background/Purpose: RA is characterized by the production of autoantibodies including anti-citrullinated protein antibodies (ACPAs).1 ACPAs are considered a prognostic indicator for more severe RA and…Abstract Number: 1432 • 2017 ACR/ARHP Annual Meeting
The Prognostic Value of IgA Subtypes of Rheumatoid Factor and Anti-Citrullinated Protein Antibodies (ACPA) for Prediction of Therapeutic Responses to TNF Inhibitory Therapy in Patients with Rheumatoid Arthritis
Background/Purpose: Rheumatoid factor (RF) and Anti-Citrullinated Protein antibodies (ACPA) are the most specific diagnostic markers of rheumatoid arthritis (RA). These antibodies are predominantly of the…Abstract Number: 413 • 2017 ACR/ARHP Annual Meeting
Economic Burden Associated with Anti-Cyclic Citrullinated Peptide Antibody Positivity in Patients Newly Diagnosed with RA
Background/Purpose: Anti-cyclic citrullinated peptide (anti-CCP) antibody positivity has been suggested as a strong predictor of joint erosion as well as a potential biomarker for guiding…Abstract Number: 1454 • 2017 ACR/ARHP Annual Meeting
Association of Poor Prognostic Factors with Medication Persistence Among Adult RA Patients within a Community of Rheumatology Clinics
Background/Purpose: A fixed treatment paradigm often exists for Rheumatoid Arthritis(RA) patient(pts)1. However, RA is a heterogeneous disease and differences in pts’ serostatus affect disease progression.…Abstract Number: 432 • 2017 ACR/ARHP Annual Meeting
ACPA and RF As Predictors of Sustained Clinical Remission in Rheumatoid Arthritis Patients: Data from a Rheumatoid Arthritis Cohort
ACPA and RF as Predictors of Sustained Clinical Remission in Rheumatoid Arthritis Patients: Data From a Rheumatoid Arthritis CohortBackground/Purpose: Positive serology for anti-citrullinated protein antibody…Abstract Number: 2012 • 2017 ACR/ARHP Annual Meeting
First Description of Tenosynovitis Prevalence in a Large Cohort of ACPA-Positive Patients
Background/Purpose: Tenosynovitis has been regarded as a feature of RA, although its true prevalence in early stages has not been firmly established. The aim of…Abstract Number: 459 • 2017 ACR/ARHP Annual Meeting
Disease Course in Seronegative RA Patients Classified According to the 2010 ACR/EULAR Criteria
Background/Purpose: The development of the 2010 classification criteria for rheumatoid arthritis (RA) has led to a redefinition of the patient population, including classification of seropositive…Abstract Number: 2016 • 2017 ACR/ARHP Annual Meeting
Favourable Changes in Power Doppler Scores in the Feet over 1-Year in an Early Rheumatoid Arthritis Cohort: The Role of Rheumatoid Factor and Anti–Citrullinated Protein Antibody
Background/Purpose : MTP joints are seldom examined in routine clinical visits. As such, it is important to understand how the standard treatment of patients with…Abstract Number: 478 • 2017 ACR/ARHP Annual Meeting
Ectopic Lymphoid Tissue in the Lung Is Uniquely Associated with the ACPA IgA Isotype Even in Absence of Classifiable RA
Background/Purpose: Antibodies to citrullinated protein antigens (ACPA) precede the development of rheumatoid arthritis (RA) and may be generated in the lung of established and preclinical…
