Rheumatoid factor (RF), anticyclic citrullinated peptides (Anti-CCP), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) are used as disease markers for rheumatoid arthritis (RA). However, correlation of disease activity score (DAS) 28 with autoantibodies and inflammatory markers has not been studied in detail. Here, we have made an attempt to determine the association of DAS-28 with autoantibodies and inflammatory markers among the North Indian population. Further, we investigated the potential of subsets of autoantibodies in RA diagnosis. Disease activity was calculated by DAS-28-ESR calculator and levels of disease markers were estimated in serum. We noticed positive correlation between DAS-28, CRP (r=0.63, p=0.00) and ESR (r=0.72, p=0.00). Moderate and weak correlation was found with RF (r=0.41, p=0.00) and anti-CCP (r=0.25, p=0.011), respectively. Patients with positive subsets of both autoantibodies (RF+/Anti-CCP+) have shown a positive correlation with DAS-28. In our study, we found that the presence of RF and Anti-CCP in patient sera can increase the early detection rate of disease. But, for the diagnosis of disease in seronegative patients, more studies on biomarkers are required. |
