Abstract:

  Background : Ulcerative colitis an inflammatory bowel disease (IBD) and chronically idiopathic immune related that associates with extraintestinal manifestations such as arthritis. Despite of the highly specificity ofanti-cyclic citrullinated peptide (CCP) antibodies for rheumatoid arthritis, their role in IBD remains unclear . There are only a few studies on the prevalence of anti-CCP antibodies in patients with IBD.This study aimed to assess the prevalence of anti- CCP antibodies in ulcerative colitis and to investigate possible associations with their clinical and laboratory characteristics.   Methods: In this cross-sectional study, 93 consecutive patients with ulcerative colitisreferred to gastroenterology clinics in Razi referral hospital of Rasht, Iran, from September 2010 to September 2011. Rheumatologic examination, demographic data and clinical presentation of patients were recorded on specially prepared data sheets . Blood sample was collected for assessment of anti-CCP and other laboratory tests. Data were analyzed by the Chi square test, Fisher Exact test and student t test, using the SPSS 20 software for Windows, and P value less than 0.05 was considered significant.   Results: Of 93 patients, anti-CCP antibodies detected in 10.8% of cases (CI 95%: 4.5-17.1%). There were a significant relation between the prevalence of anti CCP positivity and aphthous ulcers and ocular manifestations whereas other parameters were not significantly related.   Conclusion: Anti CCP may have a possible role in some ulcerative colitis manifestations but there was no association between the presence of these antibodies and activity or extension of inflammatory colitis. We suggest other studies especially molecular studies to investigate other aspects of these antibodies in IBD patients.

Anti-Cyclic Citrullinated Peptide Antibodies and Severity of Interstitial Lung Disease in Women with Rheumatoid Arthritis

OBJECTIVE To evaluate whether serum titers of second-generation anticyclic citrullinated peptide antibodies (anti-CCP2) are associated with the severity and extent of interstitial lung disease in rheumatoid arthritis (RA-ILD). METHODS In across-sectional study, 39 RA-ILD patients confirmed by high-resolution computed tomography (HRCT) were compared with 42 RA without lung involvement (RA only...

Role of anti cyclic citrullinated peptide antibodies in erosive disease in patients with rheumatoid arthritis.

BACKGROUND & OBJECTIVES Antibodies to cyclic citrullinated peptide (CCP) are a recently described marker in rheumatoid arthritis (RA), which are said to connote aggressive disease. No data on these antibodies are available from India. We undertook this study to evaluate the role of second generation anti CCP antibodies (anti CCP-2) in predicting erosive disease in Indian patients with rheumatoi...

diagnostic value of anti-cyclic citrullinated peptide antibodies in patients with rheumatoid arthritis

objective: anti-cyclic citrullinated peptide (anti-ccp) antibodies are highly specific markers for rheumatoid arthritis (ra) and useful for predicting rheumatoid arthritis (ra) development and progression. we assessed the diagnostic value of anti-ccp antibodies in our patients with ra. materials and methods: anti-ccp antibodies and rheumatoid factor (rf) titers were determined in 247 serum sam...
