Under the heading of ‘Anti-CCP antibody-positive’, the first line should read ‘HLA-shared epitope-negative’, and the second line should read ‘HLA-shared epitope-positive’. Similarly, under the heading ‘Anti-CCP antibody-negative’, the first line should read ‘HLA-shared epitope-negative’ and the second line should read ‘HLA-shared epitope-positive’. The correct table is given here as Table 1 (a ...
I n this issue of the Annals, Freemer et al report an association between smoking and dsDNA autoantibody production in systemic lupus erythematosus (SLE). The authors note that exposure to tobacco smoke has previously been associated with several autoimmune diseases, including rheumatoid arthritis (RA) and SLE. In RA, cigarette smoking has been associated with rheumatoid factor (RF) positive bu...
INTRODUCTION There is increasing evidence that autoantibodies and immune complexes (ICs) contribute to synovitis in rheumatoid arthritis (RA), yet the autoantigens incorporated in ICs in RA remain incompletely characterised. METHODS We used the C1q protein to capture ICs from plasma derived from human RA and control patients. Antibodies specific for immunoglobulin were used to detect ICs, and...
OBJECTIVE Autoantibodies have been demonstrated in single serum samples from healthy subjects up to 10 years before they developed rheumatoid arthritis (RA). However, the time course for the development of antibodies before onset of clinical RA is unknown, nor is it known which antibody, or combinations of antibodies, might be most sensitive or specific for predicting future development of the ...
OBJECTIVES To determine which variables at baseline are predictive for the development of rheumatoid arthritis (RA) from palindromic rheumatism (PR) in a Japanese population. METHODS Anti-cyclic citrullinated peptide (anti-CCP) antibodies, joint involvement pattern, genotypes of HLA-DRB1, peptidylarginine deiminase (PADI4), and protein tyrosine phosphatase (PTPN22) were examined in 28 patient...
Antibodies directed to citrullinated proteins (e.g. anti-CCP [cyclic citrullinated peptide] antibodies) are highly specific for rheumatoid arthritis (RA). These antibodies are produced at the site of inflammation in RA, and therefore citrullinated antigens are also expected to be present in the inflamed synovium. We discuss literature showing that the presence of citrullinated proteins in the s...
In this report, we describe a 61-year-old man that presented with isolated pulmonary vasculitis and a positive anti-cyclic citrullinated peptide (CCP) antibody. Within a few months, the patient developed the symmetric polyarthritis consistent with rheumatoid arthritis (RA). Because the anti-CCP antibody is highly specific for RA and vasculitis is a known association of RA, we suspect the pulmon...
The goal of this study was to identify single-locus and epistasis effects of SNP markers on anti-cyclic citrullinated peptide (anti-CCP) that is associated with rheumatoid arthritis, using the North American Rheumatoid Arthritis Consortium data. A square root transformation of the phenotypic values of anti-CCP with sex, smoking status, and a selected subset of 20 single-nucleotide polymorphism ...
INTRODUCTION Recently, arrays have become available that allow the simultaneous analysis of several anti-citrullinated protein antibody (ACPA) reactivities using distinct citrullinated peptides. Such assays are designed for exploratory studies. The interpretation of positive antibody reactivities can best be made if the diagnostic and prognostic value of a multiplex array in an early arthritis ...
OBJECTIVE Recent evidence has highlighted a major genetic contribution to radiographic damage in rheumatoid arthritis (RA). The objective of this study was to determine whether genetic variants in the loci for interleukin-1 (IL-1), IL-6, IL-10, protein tyrosine phosphatase N22 (PTPN22), and selenoprotein S are associated with radiographic damage. METHODS Modified Larsen scores of radiographic...
