According to the clinical response, anti-TNFalpha agents seem to reduce IgM, IgG and IgA rheumatoid factor levels. More interestingly, high pretreatment levels of IgA rheumatoid factor are associated with a poor clinical response to TNFalpha inhibitors.

BackgroundTo assess whether, in the real world of three early arthritis clinics, early referral could allow the best outcome, ie, remission, to be reached, and whether reaching the outcome was more dependent on therapy than on disease duration or vice versa.Methods1795 patients with early arthritis (symptom duration ≤12 months) were entered into a prospective follow-up study. 711 patients (39.6%) were diagnosed with rheumatoid arthritis (RA). Each RA patient was treated according to the local algorithm, in three tertiary referral centres (representing a small province, a medium sized province and a metropolitan area, respectively). Remission, defined using the disease activity score in 28 joints (DAS28 <2.6) and American College of Rheumatology (ACR) criteria, was the major outcome evaluated at the 12-month follow-up.ResultsDAS28 remission was achieved in 34.3% (range 19.5–49%) of RA patients and ACR remission in 15.2% (range 8.5–20.6%). At the multivariate logistic regression analysis only two variables emerged as predictors of the major outcome: being in very early rheumatoid arthritis (VERA; less than 12 weeks symptom duration at the time of first treatment) and being on disease-modifying antirheumatic drugs (DMARD) within 3 months from disease onset. Among RA patients in remission, only 10% of VERA subjects received an anti-TNF blocker compared with 32.2% of non-VERA patients (p=0.002, OR 0.23, 95% CI 0.09 to 0.64).ConclusionsIn a real-world setting, the 12 weeks disease duration and an early intervention with DMARD represent the most significant opportunities to reach the major outcome, ie, remission of RA. Moreover, VERA represents a window of opportunity in terms of cost saving.

Objective. To analyze the safety of our biopsy technique and the effectiveness of minor salivary gland biopsy (MSGB) for the diagnosis of Sjö gren's syndrome (SS) and amyloidosis. Methods. We conducted a retrospective analysis of 452 patients with suspected SS and 50 with suspected amyloidosis and negative periumbilical fat aspiration analysis who underwent MSGB at a single center. Diagnostic evaluation for SS included Schirmer's test, unstimulated whole salivary flow, detection of antinuclear antibodies and anti-SSA/SSB, erythrocyte sedimentation rate, C-reactive protein, IgM rheumatoid factor, and serology for hepatitis C virus. For all biopsy samples, a cumulative focus score on multilevel sections was calculated. SS was diagnosed according to American-European Consensus Group (AECG) criteria. Histologic evaluation for amyloidosis was performed using Congo red staining and polarized-light microscopy. Adverse events were recorded on a questionnaire immediately after the procedure and 7 days, 14 days, and 6 months thereafter. Results. Sixty-four patients (12.7%) reported transient adverse events: 40 paresthesias lasting <7 days, 17 paresthesias lasting <14 days, 27 cases of local swelling, and 8 external hematoma. One patient has had local paresthesia for 2 years. A total of 498 (99.2%) samples provided adequate material for histologic analysis. Of 452 patients evaluated for SS, 378 were finally evaluated. Ninety-three patients (24.5%) had a cumulative focus score >1, and 87 (94.5%) of 93 satisfied the AECG criteria. Classification of SS was possible for 124 (32.8%) of 378 patients. In 51 (41%) of 124, MSGB was essential to reach the number of criteria needed for classification. Of 50 patients evaluated for amyloidosis, 10 (20%) had positive Congo red staining. Conclusion. MSGB is a simple, safe, and reliable tool for the diagnosis of SS and amyloidosis, and therefore is suitable for more extensive application.

A cohort of rheumatoid arthritis (RA) patients in the Lombardy Rheumatology Network (LOHREN) registry and receiving anti-TNF therapy was evaluated after 6, 12, 24, and 36 months. Of the 1114 patients in the registry 1064 met the clinical criteria for inclusion with 519 receiving infliximab, 303 adalimumab, and 242 etanercept. The therapeutic survival curve of these patients showed that the likelihood of continuing anti-TNF therapy was 78.8% after 12 months, 65.2% after 24 months, and 52.9% after 36 months, with a risk of dropout similar for inefficacy and adverse events. There were 405 anti-TNF therapy discontinuations (38.1%): 180 (16.9%) due to inefficacy, 194 (18.2%) adverse events, and 31 (2.9%) other reasons. Four deaths (2 septicemia, 1 postinfective cerebritis, 1 heart failure) were considered to be related to anti-TNF therapy. Of the discontinuations, 219 (54.1%) occurred within the first 12 months: 110 due to adverse events, 89 inefficacy, and 20 due to other reasons. After 36 months, the likelihood of survival on etanercept (62.5%) was significantly greater than the likelihood of survival on infliximab (49.1%) or adalimumab (53.6%). A higher risk of therapy discontinuations due to adverse events was associated with increasing age, a corticosteroid > 5 mg/day, a high erythrocyte sedimentation rate (ESR), a higher risk of therapy discontinuations due to inefficacy was associated with the previous use of > or = 4 disease-modifying antirheumatic drugs (DMARDs) and a high ESR. Comorbidities, increasing DAS28 values and co-therapy with methotrexate were associated with a lower risk of discontinuation.

Conclusion. Anti-HBc positivity in HBsAg-negative patients is a sign of previous HBV infection and does not indicate chronic hepatitis. In these patients, anti-TNF␣ therapy appears to be quite safe, as no HBV reactivation was found in our study. Nevertheless, careful monitoring is necessary.

Introduction The purpose of this study was to investigate the prevalence of cyclic citrullinated peptide antibodies (anti-CCP) in patients with primary Sjögren syndrome (pSS) and its correlation with clinical and laboratory data.
