Clin Rheumatol ; This bacterium contains a citrullinated form of the alpha-enolase protein Anti-citrullinated protein antibodies in rheumatoid arthritis Ac anticuerpoe PCC English translation: Los controles fueron seleccionados de los familiares del paciente y pareados 1: Participation is free and the site has a strict confidentiality policy.

Annals of Internal Medicine. A similar but reinforced behavior of oxidative damage biomarkers was observed in case of negative anti-CCP and non-smoking habit. Clin Chem ; View Ideas submitted by the community.

Clin Biochem ; Automatic update in Therefore, our hypothesis is that oxidative damage markers could be useful to diagnose RA patients in an early stage.

Thus, good sensitivity and specificity was observed when using together traditional markers and LOOH, especially in negative anti-CCP or non-smokers patients.

Clinical Rheumatology ; Sensitivity and specificity were calculated using ROC curves. The presence of autoantibodies against citrullinated proteins in rheumatoid arthritis patients was first described in the mids when the biochemical basis of antibody reactivity against keratin and filaggrin was investigated.

Moreover, smoking is the most important environmental factor involved in RA pathogenesis 2,3 and a source of free radicals 4causing oxidative stress which is defined as the imbalance between the oxidative and anti-oxidative pathways of the body. Curr Opin Rheumatol ; Despite the development of new specific markers and diagnostic criteria 1there is still an unacceptable delay in the diagnosis of RA, related to permanent disability. How to cite this article. Plasma total antioxidant capacity, lipid peroxidation, and erythrocyte antioxidant enzyme activities in patients with rheumatoid arthritis and osteoarthritis.

The classical markers showed the expected diagnosis performance for a sample of patients with early RA 1where the addition of anti-CCP has not led to significant improvements in sensitivity 10, The intra and inter-assay coefficient of variation CV were 4.

Moreover, analysis of the correlation of anti-CCP antibody titre with RA disease activity yielded conflicting results. Navarro 2C. The variables considered included: In the subgroup of smokers, sensitivity, specificity and area under the ROC curve did not increase when markers of oxidative damage were added to the model Table 2.

Acknowledgments The authors would like to thank all participants who took part in this study. The Wilcoxon matched-pairs signed-ranks and the McNemar tests were used to compare continuous and dichotomous variables between case and control groups, respectively. Relative percent frequencies were used for categorical variables. HLA genotypes were established anticuerpo first, PCR sequence amplification using sequence-specific primers and then, complete sequencing of the product.

Furthermore, it has been shown that oxidative stress is related with the emergence and development of RA 5,6 and it may act even before the onset of the disease 7,8. Besides the development of new markers and diagnostic criteria for rheumatoid arthritis RAmany patients are still diagnosed after several years of symptoms. English PRO pts in category: Antibodies to citrullinated alpha-enolase peptide 1 are specific for Based on our initial hypothesis, these results show that oxidative damage markers can help to early diagnosis of RA when sensitivity is required or anti-CCP antibodies are negative.
