| Abstract | The Diagnostic Value of Anti-Cyclic Citrullinated Peptide Antibodies (anti-CCP) in Patients with Rheumatoid Arthritis A cross-sectional study was carried out to analyze the prevalence of anti-CCP antibodies and IgM RF in the sera of 160 randomly selected patients from the Rheumatology Department: 60 with RA, 50 with other rheumatic diseases (non-RA), 50 healthy controls (HC). The mean age of the group was 50.06+/-11.9 years. There were 141 females (88.1%) and 19 males (11.9%). RA patients fulfilled the revised ACR criteria. The mean duration of the disease was 82.4 months. Anti-CCP ELISA kit and IgM RF Latex test were used. The mean anti-CCP values were as follows: RA 60.4+/-57.6, non-RA 2.1+/-3.6, HC 1.3 +/-0.4 U/mL. Respectively, the mean values of IgM RF were: RA 515.8+/-525, non-RA 102+/-294, HC 15+/-57.5. Forty out of 60 (66.6%) RA patients were anti-CCP positive. Forty one out of 60 (68.3%) RA patients were positive for IgM RF. As expected, anti-CCP showed comparable sensitivity (66.8% vs. 68.3%) and higher specificity (98% vs. 87%) than IgM RF, at optimal cut-off values. The presence of either anti-CCP or IgM RF increased the testing sensitivity for the diagnosis of RA to 76.6%. AUC was greater for anti-CCP than for IgM RF (0.92 vs. 0.82). Dijagnostičko Značenje Anti-Cikličnih Citruliniranih Peptidnih Antitela (anti-CCP) Kod Pacijenata Sa Reumatoidnim Artritisom Radi utvrđivanja dijagnostičke senzitivnosti i specifičnosti anti-cikličnih citruliniranih peptidnih antitela anti-CCP, kao novog testa za RA urađena je «cross-sectional» studija na Reumatološkoj klinici u Skoplju. Ispitivana grupa sastojala se od 60 bolesnika s reumatoidnim artritisom koji su ispunjavali ACR kriterijume. Kontrolnu grupu 1 sačinjavali su bolesnici sa drugim reumatskim bolestima (50 non-RA), a kontrolnu grupu 2 zdrave osobe (50 ZO). Obuhvaćeni su bolesnici oba pola, 141 žena (88, 1%) i 19 muškaraca (11,9%) prosečne starosti 50,06+/-11,9 godina, dužine trajanja bolesti 82,4 meseca. Upotrebljeni su anti-CCP ELISA kit i IgM RF Latex test. Srednje vrednosti za anti-CCP antitela bile su: RA 60,4+/-57,6, non-RA 2,1+/-3,6, zdravi 1,3 +/-0,4 U/mL. Srednje vrednosti za IgM RF bile su sledeće: RA 515,8+/-525, non-RA102+/-294, zdravi 15 +/-57,5. Četrdeset RA bolesnika (40/60, 66,6%) bili su anti-CCP pozitivni, a 41/60 68,3% bili su IgM RF pozitivni. Kao što smo očekivali, anti-CCP antitela pokazala su skoro identičnu senzitivnost (66,8% vs. 68,3%), ali višu specifičnost (98% vs. 87%) u poređenju sa IgM RF. Pozitivnost za anti-CCP ili IgM RF rezultira povećanjem dijagnostičke senzitivnosti za RA (76,6%). Oblast pod krivom bila je veća kod anti-CCP antitela u odnosu na IgM RF (0,92 vs. 0,82). |
