“Anti-cyclic citrullinated peptide (anti-CCP) antibodies are well-established serological markers that show high sensitivity and specificity in early rheumatoid arthritis (RA) and are associated with bone erosions of RA. However, some patients subsequently progress to RA even if there is no presence of anti-CCP antibodies in an early

stage. The aim of this study is to evaluate the diagnostic utility of matrix metalloproteinase-3 (MMP-3), high-sensitivity C-reactive protein (hsCRP) and IgM rheumatoid factor for predicting RA in anti-CCP-negative patients with recent-onset undifferentiated arthritis (UA). Baseline levels of those markers were measured at the entry of the study. A total of 99 patients with UA were included, among them 44 patients (44.4 %) had been classified as having RA by a skilled rheumatologist PCI-32765 manufacturer at some

point during 1-year follow-up. Of these 99 patients, 34 patients (34.3 %) had anti-CCP antibodies and 65 patients (65.7 %) had no anti-CCP antibodies. Eleven patients who were anti-CCP-negative developed RA. We compared sensitivity, specificity, positive predictive value and negative predictive value of serum markers of these anti-CCP-negative RA patients. The combined usage of MMP-3 with hsCRP is relatively superior to other markers as predictors of RA.”
“Our objective was Selleckchem Alpelisib to determine the prevalence juvenile idiopathic arthritis (JIA) in Sharkia Governorate, Egypt. Population-based study was performed to identify the prevalence of JIA in Sharkia Governorate, Egypt, between November 2009 and November 2010. Prevalence of JIA was 3.43 per 100,000 (95 % CI 3.1-4.3). Prevalence in boys was 2.58 per 100,000 (95 % CI 2.4-3.6) and in girls 4.33 per 100,000 (95 % CI 3.3-5.1). Uveitis presented in 19.7 % of cases, antinuclear antibody in 48.5 %, and rheumatoid factor in 27.2 %. Oligoarthritis representing 52.2 % of the total population, and enthesitis-related Axenfeld syndrome arthritis presented only in 6 patients. No cases

of undifferentiated arthritis or psoriatic arthritis were found. This is the first epidemiological study of JIA in Sharkia, Egypt. Oligoarthritis was the most common subtype.”
“Our aim was to determine whether the Fc receptor-like 3 (FCRL3) -169 C/T (rs7528684) polymorphism confers susceptibility to systemic lupus erythematosus (SLE). A meta-analysis was conducted on the associations between the FCRL3 -169 C/T polymorphism and the SLE. A total of nine sets of comparisons containing 3,628 patients and 6,490 controls were considered. The meta-analysis showed no association between the SLE and the FCRL3 -169 C allele in all study patients (odds ratio [OR] = 0.999, 95 % confidence interval [CI] = 0.925-1.080, p = 0.986).
