- Abstract Number: 2922 • 2014 ACR/ARHP Annual Meeting - Association of Single Nucleotide Polymorphisms of PADI4 Gene with Susceptibility to Rheumatoid Arthritis-Related Lung DiseaseBackground/Purpose Rheumatoid arthritis (RA) causes a myriad of pulmonary complications, including bronchiolitis and bronchiectasis, pleuritis, and interstitial lung disease (ILD). Recently, several studies have shown…
- Abstract Number: 2923 • 2014 ACR/ARHP Annual Meeting - Protein Quantification Using Mass Spectrometry Methods to Predict Response to Abatacept and Methotrexate Combination Therapy in Rheumatoid ArthritisBackground/Purpose: Targeted biologic therapies with different mechanisms of action are commonly used in RA. Abatacept is a recombinant fusion protein that inhibits T-cell co-stimulatory molecules…
- Abstract Number: 2924 • 2014 ACR/ARHP Annual Meeting - Clinical Utility of Random Anti-TNF Drug Level Testing and Measurement of Anti-Drug Antibodies on Long-Term Treatment Response in Rheumatoid ArthritisBackground/Purpose Up to 40% of RA patients on anti-TNF treatment fail to respond either due to primary inefficacy or loss of response. One explanation is…
- Abstract Number: 2925 • 2014 ACR/ARHP Annual Meeting - Serum MMP-3 Predicts a Subgroup with No Radiographic Progression in Rheumatoid Arthritis Patients with Low-Dose Methotrexate (MTX) MonotherapyBackground/Purpose: Studies have shown that treating rheumatoid patients with methotrexate (MTX) monotherapy initially and later providing an option to step up to combination therapy produces…
- Abstract Number: 2926 • 2014 ACR/ARHP Annual Meeting - Calprotectin Serum Levels Reflect Residual Inflammatory Activity in Patients with Rheumatoid Arthritis and Psoriatic Arthritis on Clinical Remission or Low Disease Activity Undergoing TNF-Antagonists TherapyBackground/Purpose: Calprotectin is a major S100 leucocyte protein, is associated to disease activity in rheumatoid arthritis (RA) and Psoriatic Arthritis (PsA) patients. Calprotectin is a potentially…
- Abstract Number: 2927 • 2014 ACR/ARHP Annual Meeting - Baseline Serum Interferon Beta/Alpha Ratio Predicts Response to Tumor Necrosis Factor Alpha Inhibition in Rheumatoid ArthritisBackground/Purpose Response to tumor necrosis factor alpha (TNF-α) inhibition is variable in rheumatoid arthritis (RA). Previous studies have suggested that circulating type I interferon (IFN)…
- Abstract Number: 2928 • 2014 ACR/ARHP Annual Meeting - Serum IL-33 Level Is Increased in Rheumatoid Arthritis and Predicts Response to Rituximab in Combination with High Serum IgG Level and Autoantibody Positivity: An Open-Label, Prospective, Multicentre Biological TrialBackground/Purpose . The recent discovered cytokine interleukin-33 (IL33) could be involved in B-cell activation as well as in RA pathophysiology. After a whole-blood transcriptomic analysis…
- Abstract Number: 2929 • 2014 ACR/ARHP Annual Meeting - Molecular Diagnostics for Patient Subsetting in Sjögren’s SyndromeBackground/Purpose Sjögren’s syndrome (SS) is a chronic autoimmune disease which targets exocrine glands, particularly salivary and lacrimal glands. While all SS patients have abnormal secretory…
- Abstract Number: 2930 • 2014 ACR/ARHP Annual Meeting - Precisely Quantified Fibrosis in Labial Salivary Glands Predicts Sjögren’s Syndrome Classification in a Multiple Regression ModelBackground/Purpose: Primary Sjögren's Syndrome (pSS) is a systemic, progressive autoimmune exocrinopathy that presents diagnostic challenges. Focal lymphocytic infiltrates in labial salivary gland (SG) biopsies, serum…
- Abstract Number: 2931 • 2014 ACR/ARHP Annual Meeting - Longitudinal Examination with Salivary Gland Ultrasonography (SGUS) of Patients with Primary Sjogren’s Syndrome: A Single Center ExperienceBackground/Purpose: Recently, convincing data have been published on the diagnostic value of salivary gland ultrasonography (SGUS) in primary Sjögren’s syndrome (pSS). However, a limited number…
