Excess in Prevalence of Functional Disability in Patients with Rheumatoid Arthritis: Does Serologic Status Matter?
Background/Purpose: Despite the advances in treatment of rheumatoid arthritis (RA) over the recent decades, many patients with RA do not achieve remission or full physical…Abstract Number: 213 • 2018 ACR/ARHP Annual Meeting
Excessive Risk of Major Cardiovascular Events in Sero-Positive Rheumatoid Arthritis and in Patients with Active Disease
Background/Purpose: Rheumatoid arthritis (RA) is a known risk factor for the development of cardiovascular disease (CVD). However, the influence of RA on the prognosis after…Abstract Number: 568 • 2018 ACR/ARHP Annual Meeting
Change in RF and Anti-CCP Isotype Levels in RA Patients Treated with Anti-TNF, Abatacept, Rituximab or Tocilizumab and Correlation with Clinical and Radiographic Outcomes: Data from a Randomized Trial
Background/Purpose: In rheumatoid arthritis (RA), little is known about the prognostic relevance of the change in autoantibody (ab) levels. Seroconversion was reported to be associated…Abstract Number: 1452 • 2018 ACR/ARHP Annual Meeting
Combination of Ultrasound Power Doppler-Verified Synovitis and Seropositivity Accurately Identifies Patients with Early Rheumatoid Arthritis
Background/Purpose: We conducted this retrospective study to determine objective and comprehensive diagnostic criteria for early rheumatoid arthritis (RA) that are based on ultrasound (US) and…Abstract Number: 482 • 2017 ACR/ARHP Annual Meeting
The Link between ACPA and Erosion Development: Is ACPA Sufficient? an Association Study in Clinically Suspect Arthralgia
Background/Purpose: Anti-citrullinated protein antibodies (ACPA) associate with more severe joint erosions in rheumatoid arthritis (RA), but the underlying mechanism is unclear. Recent in vitro and…Abstract Number: 1250 • 2017 ACR/ARHP Annual Meeting
Outcomes in Real-World Patients with Early Aggressive Rheumatoid Arthritis
Background/Purpose: The window of opportunity to address early rheumatoid arthritis (RA) in patients (pts) is well documented. However early aggressive (agr) RA needs further study…Abstract Number: 1376 • 2017 ACR/ARHP Annual Meeting
Diagnostic Performance of 7 Different Anti-Cyclic Citrullinated Peptide Antibody and 6 Rheumatoid Factor Assays in a Primary Diagnostic, Consecutive Rheumatological Population in a Secondary Care Hospital
Background/Purpose: The clinical diagnosis of rheumatoid arthritis (RA) remains a challenge, making serological markers most interesting. The 2010 ACR/EULAR classification criteria for RA take into…Abstract Number: 1402 • 2017 ACR/ARHP Annual Meeting
In RA, Becoming Seronegative over the 1st Year of DMARD Treatment Does Not Improve Chances of Drug-Free Remission in the Long-Term
Background/Purpose: Patients with RA harbor autoantibodies of various isotypes and directed against several post-translational modifications. Baseline seropositivity is a poor prognostic factor for sustained drug-free…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: 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: 1819 • 2017 ACR/ARHP Annual Meeting
Delay of Diagnosis and Treatment in Seronegative Rheumatoid Arthritis: Missing the Window of Opportunity
Background/Purpose: Evidence supports a therapeutic window of opportunity in early rheumatoid arthritis (RA), during which DMARD therapy most effectively improves clinical outcomes. The 2010 ACR/EULAR…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…
