Elevated levels of IgM and IgA antibodies to Proteus mirabilis and IgM antibodies to Escherichia coli are associated with early rheumatoid factor (RF)-positive rheumatoid arthritis.
OBJECTIVE Antibodies to Proteus mirabilis were previously detected in patients with established rheumatoid arthritis (RA). We examined the prevalence of antibodies to P. mirabilis and their associations with RA in early synovitis patients. METHODS Two hundred and forty-six patients with inflammatory arthritis for less than 1 yr were prospectively evaluated for 1 yr. Of these patients, 30% had...
متن کاملتعیین فاکتور روماتوئید به‌روش ELISA و لاتکس: یک مطالعه مقطعی
Background: Rheumatoid factor (RF) is an IgM antibody against the Fc portion of IgG, which together form an immune complex. RF is an important criterion in the diagnosis of early-stage rheumatoid arthritis (RA) and prognosis of RA pathogenesis, as higher levels of RF indicate a higher possibility of more damage. Although 2/3 to 3/4 of patients that undergo ordinary standard tests and have final...
متن کاملDetection of Rheumatoid Factors in Sera and Biopsy Lesions of Vitiligo Patients
Background: Vitiligo is a dermatological disorder of unknown etiology with a common incidence in southern Iran. Presence of autoantibodies to melanocyte antigens suggested an autoimmune basis of the disease. Objective: In this study, the presence of rheumatoid factor (RF) in sera and skin biopsies of vitiligo patients was investigated. Methods: The presence of RF in sera of 35 vitiligo and 32 n...
متن کاملبررسی اندازه‌گیری آنتی‌بادی ضد سیترولین در تشخیص بیماران مبتلا به آرتریت روماتوئید و مقایسه با سایر بیماری‌های روماتیسمی و افراد به ظاهر سالم
Background and Aim: Rheumatoid arthritis (RA) is the most common autoimmune rheumatic disease, which requires specific diagnostic tests for it’s’ diagnosis. However specific and practical tests for its diagnosis are lacking. We evaluated the diagnostic accuracy of Anti-cyclic citrullinated peptide antibodies (Anti-CCP) in the diagnosis, prognosis and determination of the severity of RA.Mate...
متن کاملDiagnostic and clinical value of anti-cyclic citrullinated peptide antibodies compared with rheumatoid factor isotypes in rheumatoid arthritis.
OBJECTIVE To assess the additional diagnostic and clinical value of the second test generation of anti-cyclic citrullinated peptide antibodies (CCP2) compared with rheumatoid factor isotypes (IgG-RF, IgA-RF, IgM-RF) in patients with rheumatoid arthritis. METHODS This was a prospective study on 715 patients: rheumatoid arthritis (n = 295), degenerative or other inflammatory joint disease (n = ...
