ObjectivesTo compare the effectiveness of rituximab versus an alternative tumour necrosis factor (TNF) inhibitor (TNFi) in patients with rheumatoid arthritis (RA) with an inadequate response to one previous TNFi.MethodsSWITCH-RA was a prospective, global, observational, real-life study. Patients non-responsive or intolerant to a single TNFi were enrolled ≤4 weeks after starting rituximab or a second TNFi. Primary end point: change in Disease Activity Score in 28 joints excluding patient's global health component (DAS28-3)–erythrocyte sedimentation rate (ESR) over 6 months.Results604 patients received rituximab, and 507 an alternative TNFi as second biological therapy. Reasons for discontinuing the first TNFi were inefficacy (n=827), intolerance (n=263) and other (n=21). A total of 728 patients were available for primary end point analysis (rituximab n=405; TNFi n=323). Baseline mean (SD) DAS28-3–ESR was higher in the rituximab than the TNFi group: 5.2 (1.2) vs 4.8 (1.3); p<0.0001. Least squares mean (SE) change in DAS28-3–ESR at 6 months was significantly greater in rituximab than TNFi patients: −1.5 (0.2) vs −1.1 (0.2); p=0.007. The difference remained significant among patients discontinuing the initial TNFi because of inefficacy (−1.7 vs −1.3; p=0.017) but not intolerance (−0.7 vs −0.7; p=0.894). Seropositive patients showed significantly greater improvements in DAS28-3–ESR with rituximab than with TNFi (−1.6 (0.3) vs −1.2 (0.3); p=0.011), particularly those switching because of inefficacy (−1.9 (0.3) vs −1.5 (0.4); p=0.021). The overall incidence of adverse events was similar between the rituximab and TNFi groups.ConclusionsThese real-life data indicate that, after discontinuation of an initial TNFi, switching to rituximab is associated with significantly improved clinical effectiveness compared with switching to a second TNFi. This difference was particularly evident in seropositive patients and in those switched because of inefficacy.

The objective of this study was to determine the prevalence, clinical pattern, and management of seronegative spondyloarthropathies (SpA) in the general adult population of Greece. This population-based study was conducted on a target adult (> or =19-year-old) population of 14,233 subjects by rheumatologists who visited households in nine dispersed areas. An interview (standardized questionnaire) was conducted, clinical evaluation and laboratory investigation were done, and established diagnostic classification criteria were used. The age-adjusted and sex-adjusted prevalence (prevalence(asa)) of SpA was 0.49% [95% confidence interval (CI): 0.38-0.60], with a male to female ratio of 5.5:1; the prevalence increased with age until the 59- to 68-year-old age group and declined thereafter. The prevalence(asa) of ankylosing spondylitis (AS) and psoriatic arthritis (PsA) was 0.24% (95% CI: 0.16-0.32) and 0.17% (95% CI: 0.10-0.24), respectively. The mean age (years) at onset was younger in AS (25.83 +/- 6.5) than in PsA (45.24 +/- 12.94) (p < 0.01). Familial clustering was noticed in 5.3% of AS probands. Sacroiliitis was observed in 39.8% and asymmetrical oligoarthritis in 40.6% of PsA patients. Fifty-nine percent of SpA patients had previously visited rheumatologists (91.3% diagnosed correctly vs 11.6% of those who visited other specialists, p < 0.0005); 56.5% of the former had taken disease-modifying antirheumatic drugs compared to none of the latter. The SpA in Greeks are as common as in other European Caucasians, with a high male preponderance. The PsA onset occurs at an older age than AS and frequently presents with a spondylitic pattern. The correct diagnosis was arrived at and appropriate treatment was given when patients consulted rheumatologists.

The prevalence of RA in the general adult population of Greece is similar to that in many other European countries; early consultation with a rheumatologist and DMARD combination therapy are associated with a better RA outcome.

These findings suggest that rheumatic diseases constitute a major public health problem and should be considered in planning undergraduate and postgraduate medical education, research and health-care services.

A lthough the development of pulmonary arterial hypertension (PAH) in mixed connective tissue disease (MCTD) is now recognised as the most important life threatening factor, an effective treatment for PAH has not been established. The response to steroid treatment of PAH related to MCTD varies. Furthermore, Raynaud's phenomenon is the most common symptom of MCTD and one symptom of the 1996 revised criteria for MCTD in Japan.
