Abstract: Tumor necrosis factor alpha (TNFalpha) is implicated in the pathogenesis of many chronic inflammatory diseases such as rheumatoid arthritis (RA), psoriasis and psoriatic arthritis (PsA), ankylosing spondylitis (AS), Crohn's disease, ulcerative colitis and uveitis. The availability of new pharmacological agents (infliximab, etanercept, adalimumab), able to selectively block the TNFalpha, has recently offered new opportunity for the treatment of these diseases. TNFalpha antagonists are different in the mechanism of action and are all effective agents in the treatment of RA and several chronic inflammatory diseases as a large number of controlled clinical trials have shown. Among biological effects of TNFalpha antagonists, the production of autoantibodies has been emphasized. This phenomenon is not correlated with the disease background, since anti-nuclear antibodies (ANA) and anti-double stranded-DNA antibodies (anti-dsDNA) induction is observed in RA as well as in spondyloarthritis (SpA) patients. Nonetheless, recent studies had reported a significant reduction in the serum titre of rheumatoid factor (RF) and/or anti-cyclic citrullinated peptide antibodies (anti-CCP) during anti-TNFalpha therapy. The TNFalpha antagonists represent a significant advance in the therapy of active RA and other chronic inflammatory diseases. However, they have distinct biological, clinical, and pharmacological properties that must be considered when selecting a drug for therapy.

Abstract: OBJECTIVE: To investigate the prevalence of antipolymer antibody (APA) in patients with fibromyalgia (FM) and to examine its association with FM severity symptoms. METHODS: The study population consisted of 79 FM patients and 75 controls: 32 with psoriatic arthritis and 43 with rheumatoid arthritis APA levels were indirectly assayed using a commercial ELISA kit from Corgenix (Westmister, Colorado, USA). Optical density (OD) values were recorded on duplicates of each of the reference and patient samples. Among clinical variables we investigated pain, measured according to visual analog scales (VAS: 0-100), fatigue, stiffness, anxiety, depression, all measured by VAS (0-100), and health status measured by Fibromyalgia Impact Questionnaire (FIQ). RESULTS: Sixteen of the 79 FM patients (20.3%) and 12/78 controls (15.4%) were positive for APAs (P = 0.536). Following ROC analysis, area under curve (AUC) was 0.49 (95% CI: 0.40, 0.58). Focusing on FM patients, we observed a correlation between APA titre and pain (tau: - 0.221; P = 0.020) and fatigue (tau: - 0.205; P = 0.032) at univariate analysis. Binomial regression analysis, controlling for clinical and demographic variables, showed that pain (PPR: 0.923; P = 0.007) and fatigue (PPR: 0.948; P = 0.024) were significantly associated with APA test sensitivity. CONCLUSIONS: APA test exhibited a low sensitivity in FM patients and it did not distinguish this group of patients from the controls enrolled in this study. Interestingly, positive APA test prevalence increased with less severe pain or fatigue.

Abstract: This study was performed to assess the utility of anti-cyclic citrullinated peptide (anti-CCP) antibodies in distinguishing between patients with rheumatoid arthritis (RA) and patients with polyarticular involvement associated with chronic hepatitis C virus (HCV) infection. Serum anti-CCP antibodies and rheumatoid factor (RF) were evaluated in 30 patients with RA, 8 patients with chronic HCV infection and associated articular involvement and 31 patients with chronic HCV infection without any joint involvement. In addition, we retrospectively analysed sera collected at the time of first visit in 10 patients originally presenting with symmetric polyarthritis and HCV and subsequently developing well-established RA. Anti-CCP antibodies and RF were detected by commercial second-generation anti-CCP2 enzyme-linked immunosorbent assay and immunonephelometry respectively. Anti-CCP antibodies were detected in 23 of 30 (76.6%) patients with RA but not in patients with chronic HCV infection irrespective of the presence of articular involvement. Conversely, RF was detected in 27 of 30 (90%) patients with RA, 3 of 8 (37.5%) patients with HCV-related arthropathy and 3 of 31 (9.7%) patients with HCV infection without joint involvement. Finally, anti-CCP antibodies were retrospectively detected in 6 of 10 (60%) patients with RA and HCV. This indicates that anti-CCP antibodies can be useful in discriminating patients with RA from patients with HCV-associated arthropathy.
