Megjegyzések:	Anti-cyclic citrullinated peptide (CCP) antibodies have emerged as sensitive and specific serological markers of rheumatoid arthritis (RA). However, antibodies to several other citrulline-containing proteins, including citrullinated fibrin and vimentin, have been detected in patients with RA, suggesting that citrulline is an essential constituent of autoantigens for RA-specific autoantibodies. We examined the diagnostic performance of the newly developed anti-mutated citrullinated vimentin (MCV) antibody assay. METHODS: Concentrations of anti-MCV, anti-CCP2, and rheumatoid factors (RF) were determined in the sera of 237 individuals: 119 patients with RA and 118 controls, including patients with other rheumatic diseases and healthy subjects. Diagnostic properties were compared by receiver-operating characteristic curve analysis. RESULTS: Using manufacturer's recommended cutoff values, sensitivity and specificity of anti-MCV antibodies were 75.6% and 91.5% in RA, compared to 66.4% and 98.3% for anti-CCP2. Introducing cutoff values to obtain the same 95% specificity resulted in decreased sensitivity of the anti-MCV test (69.7%) and increased sensitivity of the anti-CCP2 test (74.8%). At optimal cutoff levels, 29.4% of IgM RF-negative cases as well as 13.3% of anti-CCP2-negative cases in the RA group were anti-MCV-positive. Double-positivity for anti-MCV and anti-CCP2 provided 98.3% specificity with 97.5% positive predictive value in RA. CONCLUSION: Overall, the performance of the novel anti-MCV ELISA for the diagnosis of RA is similar to that of the anti-CCP2 test [area under the curve 0.853 (95% CI 0.801-0.905) vs 0.910 (95% CI 0.873-0.946); p not significant]. As the diagnostic spectrum of the anti-MCV assay is somewhat different from that of anti-CCP2, the combined application of the 2 assays can improve the laboratory diagnostics of RA.

Cím:	HLA-DR genotypes in familial rheumatoid arthritis : increased frequency of protective and neutral alleles in a multicase family / Szilvia Zsilák, János Gál, László Hodinka, Katalin Rajczy, Attila Balog, Sándor Sipka, Sándor Baráth, Anikó Kapitány, Erika Zilahi, Zoltán Szekanecz
Dátum:	2005
Megjegyzések:	We describe a unique family where each of the 5 siblings in the second generation has rheumatoid arthritis (RA). Two other members of the family have RA and systemic lupus erythematosus (SLE), respectively. No members of previous generations in the family had documented inflammatory arthritis. Due to the suspected genetic predisposition, HLA-DR genotypes were determined in the affected siblings and their parents, children, and grandchildren. We investigated the possible role of various HLA-DR alleles in the evolution of RA in this multicase family. METHODS: HLA-DRB1* alleles were determined by polymerase chain reaction using the sequence-specific primer-Olerup method. RESULTS: The most common alleles in the 6 persons with RA were HLA-DRB107 and DRB115, which are known to be protective and neutral in RA. No patient or family member carried any HLA-DR4 alleles. CONCLUSION: HLA-DRB107 and DRB115 alleles are thought to be protective or neutral in RA. However, the majority of RA patients in the family and nearly half of all family members carried these alleles, suggesting a role of these genotypes in susceptibility to RA. No RA patient in this family carried HLA-DR4 alleles. Thus, in our rare family with 6 RA cases, an unexpected genetic background may be involved in the increased susceptibility to inflammatory arthritis.
