Study of Prognostic Significance of Anti Cyclic Citrullinated Peptide Antibodies in Patients with Rheumatoid Arthritis

Background: Rheumatoid arthritis is a chronic autoimmune inflammatory disease with articular and extra-articular manifestation that affects 0.5 to 1 % of total population. Aim and Objectives: To correlate Rheumatoid factor (RF) and Anti-CCP antibody in RA, to evaluate prognostic value of RF and Anti-CCP antibody in RA. Materials and methods: Retrospective study of total 50 patients admitted to our hospital from January 2018 to December 2018 was done. All patients were diagnosed as rheumatoid arthritis as per diagnostic criteria of American College of Rheumatology. All patients had symptom duration of at least one Year. Anti-CCP and lgM-RF were evaluated in all patients. Disease activity score 28 was calculated in all patients. Radiological Damage was assessed by Larsen Score. Results: Anti-CCP and RF were significantly correlated with each other and both were seen as significant independent predictors of radiological outcomes (p value 0.01 and <0.05 respectively). Combination of these two had highest risk for erosive joint damage. Conclusion: RA is more common in female. Anti-CCP antibody and RF both in combination were associated with higher probabilities of erosive disease.
