OBJECTIVE To assess the role of anti-cyclic citrullinated peptide (CCP) antibody detection in synovial fluid (SF) of RA patients compared to OA patients. METHODS We evaluated in 25 RA subjects and 14 OA patients, presenting a knee-joint effusion, the main clinical and laboratory parameters including the number of painful and/or swollen joints, Ritchie index, morning stiffness, ESR, CRP and an...

INTRODUCTION The present study was carried out to assess whether IgA-class antibodies against cyclic citrullinated peptides (IgA anti-CCP) in recent-onset rheumatoid arthritis add diagnostic and/or prognostic information to IgG anti-CCP analysis. METHODS Serum samples were obtained from 228 patients with recent-onset (<12 months) rheumatoid arthritis at the time of inclusion in the Swedish TI...

PURPOSE To correlate the presence of anti-cyclic citrullinated peptide (anti-CCP) antibodies and rheumatoid factor (RF) with ocular symptoms typical of rheumatoid arthritis (RA). METHODS The records of 451 patients who had been examined by an ophthalmologist and tested for anti-CCP antibodies over a 3-year period at the Mayo Clinic were reviewed. Records of 255 patients with titers of anti-CC...

AIM Autoantibodies against cyclic citrullinated peptide (anti-CCP) are considered to be a sensitive and specific marker for rheumatoid arthritis (RA). This study evaluated the diagnostic and analytical performances of the automated anti-CCP assay. MATERIALS AND METHOD Sera from 80 patients with established RA, 65 from other rheumatic diseases (non-RA) and 55 from healthy controls were studied...

Second-generation assays for anti-cyclic citrullinated peptide (anti-CCP), a highly sensitive and specific marker for rheumatoid arthritis (RA), have redefined the epidemiology of RA. In the Women's Health Initiative (WHI) RA study (2009-2011), we evaluated the prevalence of anti-CCP positivity among 15,691 (10.2% of 161,808) WHI participants aged 50-79 years who reported RA. Using stored basel...

OBJECTIVE/AIM A new group of autoantibodies in Rheumatoid Arthritis (RA), the anti-cyclic citrullinated peptide (anti-CCP) antibodies directed to citrulline-containing proteins, which are of value for the severity of RA. Up to date, the relationship between anti-CCP antibodies and oxidant, anti-oxidant activity in patients with RA has not been elucidated in the previous studies. In this study w...

OBJECTIVE To compare the clinical utility of anti-cyclic citrullinated peptide (anti-CCP) antibodies and rheumatoid factor (RF) testing in predicting both functional outcome and response to treatment in early inflammatory polyarthritis (IP) patients. METHODS A total of 916 IP subjects from a primary care incidence registry (1990-1994) had anti-CCP antibody and RF status determined at baseline...

background : ulcerative colitis an inflammatory bowel disease (ibd) and chronically idiopathic immune related that associates with extraintestinal manifestations such as arthritis. despite of the highly specificity ofanti-cyclic citrullinated peptide (ccp) antibodies for rheumatoid arthritis, their role in ibd remains unclear . there are only a few studies on the prevalence of anti-ccp antibodi...

Results Eleven of 47 (23%) JIA SF samples were positive for the different anti-CCP antibody isotypes. IgM anti-CCP antibodies were positive in 9 JIA patients, including 5 oligoarthritis, 3 IgM RF+ and 1 IgM RFpolyarthritis. IgG antiCCP antibodies were positive in 8 JIA patients, including 4 oligoarthritis, 2 IgM RF+, 1 IgM RFpolyarthritis, and 1 enthesitis-related. Two IgM RF+ polyarthritis pat...

OBJECTIVE To investigate the prevalence of anti-cyclic citrullinated peptide (anti-CCP) and anti-keratin antibodies (AKA) in patients with primary Sjögren's syndrome. METHODS 149 patients with a diagnosis of primary Sjögren's syndrome according to the European/American consensus criteria were recruited from three French medical centres. The presence of anti-CCP was determined by enzyme linked...
