between patients with rheumatoid arthritis (RA) and patients with polyarticular involvement associated
with chronic hepatitis C virus (HCV) infection.
Methodology: All the patients enrolled in this study were examined in the outpatient department of
medicine unit at Lady Reading Hospital Peshawar from February to December 2010. Serum anti-CCP
antibodies and rheumatoid factor (RF) were evaluated in 29 patients with RA, 13 patients with chronic
HCV infection a associated with articular involvement and 35 patients with chronic HCV infection without
any joint involvement.
Results: Anti-CCP antibodies were detected in18 of 29 (62.1%) patients with RA, 7 of 13(53.8%) patients
having HCV with RA like arthropathy but not in a single patient with chronic HCV infection with no
articular involvement. Conversely, RF was detected in 25 of 29 (86.2%) patients with RA, 9 of 13 (69.2%)
patients with HCV-related RA like arthropathy and 8 of 31 (22.9%) patients with HCV infection without
Conclusion: This concludes that anti-CCP antibodies can be useful in discriminating patients with RA from
patients with HCV-associated arthropathy.
