Abstract: Psoriatic arthritis is an inflammatory and possibly destructive form of arthritis. As in rheumatoid arthritis and ankylosing spondylitis, the use of biological therapy in psoriatic arthritis is a therapeutic revolution: both articular and cutaneous efficacy have been shown, and some improvement is visible on radiography. The benefit-risk ratio will improve when we learn to identify more accurately the patients likely to benefit from these treatments.

Abstract: OBJECTIVES: To elaborate a how-to-use abatacept material intended to help physicians in the management of patients with inflammatory diseases treated with this drug in routine practice. METHODS: 1) Selection of the relevant domains by a rheumatologists' panel; 2) Search for published evidence in each domain; 3) Elaboration of the clinical tool guide with a 3-level gradation of evidence (evidence-based medicine EBM, official recommendations and expert's opinion). The experts were 11 academic rheumatologists with a large experience in prescribing abatacept and in managing rheumatoid arthritis. They were all members of the CRI (Club Rhumatismes et Inflammation), a section of the French Rheumatology Society dedicated to the inflammatory rheumatic diseases. Each fact sheet was reviewed by two other experts; 4) Regular updating based on medical literature and postmarketing surveillance data. RESULTS: Four domains were considered relevant: abatacept contraindications, management of side effects or associated diseases appearing during abatacept treatment, management of "practical situations" such as surgery or pregnancy, physician and patient information. After the literature analysis and discussion during an experts' meeting, a consensus was reached on: a pre-treatment checklist aimed at searching abatacept contraindications; a what-to-do document when facing side effects or associated diseases (autoimmune pathology, bacterial or viral infections, cardiovascular diseases, intolerance to abatacept, solid or haematological malignancy) or "practical situations" (surgery, pregnancy, vaccination, travel, drug-drug interactions); an example of standard information letter to be addressed to the attending physician (rheumatologist and general practitioner); an example of standard information letter to be addressed to the patient. CONCLUSION: Based on both an EBM approach and an expert's opinion approach, this abatacept clinical tool guide should provide assistance to all physicians attending patients treated with abatacept. For a better implementation in clinical practice, this tool guide will be available online at www.cri-net.com and regularly updated.

Abstract: OBJECTIVE: Although tumor necrosis factor-alpha (TNF-alpha) antagonists are effective in the treatment of refractory psoriasis, some cases have suggested that psoriasis might be induced as a result of treatment prescribed mainly for rheumatoid arthritis, ankylosing spondylitis, and Crohn's disease. To investigate anti-TNF-alpha induced psoriasis, we conducted a systematic analysis of the 6 cases we observed among our inflammatory patient cohort treated with anti-TNF-alpha (infliximab or etanercept). METHODS: We report 6 cases of psoriasis with onset during TNF-alpha antagonist therapy (infliximab and etanercept); characteristics and skin lesions are described. RESULTS: No patient had a personal or family history of psoriasis. The development of psoriasis was seen in all the types of inflammatory diseases we treated with TNF-alpha antagonists. There was great variation in the age of affected patients and in the onset of psoriasis after initiation of TNF-alpha antagonists. Both TNF-alpha antagonists studied were associated with development of psoriasis. In 2 cases psoriasis was associated with 2 different TNF-alpha antagonists in the same patient. In half our patients, skin lesions started in the inguinal and pubic regions, but palmoplantar pustulosis was also common. In half the cases, skin lesions responded favorably with topical agents despite continuation of TNF-alpha antagonist therapy. CONCLUSION: In light of previously published cases describing psoriasis or psoriasiform lesions after TNF-alpha antagonist therapy, our series strongly confirms that TNF-alpha antagonists may induce psoriasis in some patients. Further studies are needed to identify risk factors for TNF-alpha antagonist induced psoriasis.

Abstract: OBJECTIVE: To determine which inflammatory cell types are present in entheses from patients with spondyloarthropathy (SpA) compared with patients with rheumatoid arthritis (RA) or osteoarthritis (OA). METHODS: Enthesis specimens were obtained during orthopaedic procedures in eight patients with SpA, four with RA, and three with OA. After decalcification, the lymphocyte subsets (CD3, CD4, CD8, CD20) in the bone marrow component of each enthesis were measured by an immunohistochemical technique. RESULTS: Oedema and an inflammatory infiltrate were present in all the SpA specimens, being clearly predominant in the bone marrow component of the entheses. The density of all cell types in the bone marrow was significantly higher in the SpA group than in the two other groups. The cell type CD3+ showed the greatest difference between the SpA and RA groups, being increased fivefold in the SpA group. Within the SpA group, CD3+ cells were considerably more numerous than CD20+ cells-a difference from the RA group-and the predominant T cells were CD8+. CONCLUSION: Persistent oedema with an inflammatory infiltrate composed predominantly of CD8+ cells was noted in the entheses of patients with SpA, being predominant in the bone marrow. These results suggest that CD8+ cells may have a key role in local inflammation in SpAs.

Abstract: OBJECTIVE: To determine, for the first time, plasma levels of general fibronectin (Fn) and two spliced isoforms, Ed-A and Ed-B, in patients with spondyloarthropathy (SpA) in comparison with rheumatoid arthritis (RA) patients and healthy volunteers (HV). METHODS: Plasmas (EDTA) as well as clinical data, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels were collected in two groups of 10 patients fulfilling the European Spondylarthropathy Study Group criteria for SpA or the 1987 American College of Rheumatology criteria for RA. Plasmas of 21 blood donors served as controls. Plasma levels of Fns were determined by using an in-house immunocapture ELISA, using monoclonal antibodies (MAbs) against general Fn and its isoforms. RESULTS: Total Fn plasma levels were significantly higher in the SpA group (mean+/-S.D.=1387+/-569 mg/l) than in the RA group (684+/-196 mg/l; P=0.02) and in HV (303+/-211 mg/l; P<0.0001). Ed-A Fn levels appeared higher in SpA (23+/-10.4 mg/l) and RA (32.5+/-16.5 mg/l) groups than in the HV group (2.8+/-0.9 mg/l; P=0.0003 and P<0.0001, respectively), without a significant difference between SpA and RA groups. Ed-B Fn levels were higher in SpA (6.9+/-2.1 mg/l) than in RA (3.2+/-1.9 mg/l; P=0. 02) and HV (1.1+/-0.8 mg/l; P=0.0003) groups. No significant correlation was observed in SpA patients between each Fn level and clinical activity, ESR or CRP levels. CONCLUSIONS: This study showed an increase in plasma levels of Fn and Ed-B Fn in SpA patients compared with RA patients and HV, which could not be attributed solely to systemic inflammation. It may be hypothesized that Ed-A and Ed-B Fn might reflect local turnover in inflamed tissues, and that Ed-B Fn might be particularly involved in the musculoskeletal inflammatory process of SpA.

Abstract: We describe a case of a 50-year-old woman presenting articular manifestations of rheumatoid arthritis associated with severe interstitial lung involvement related to multiple pulmonary nodules. Diagnosis of diffuse pulmonary rheumatoid nodulitis was made only after video assisted thoracoscopic lung biopsies.
