Clinical assessment in psoriatic arthritis
Due to the heterogeneous clinical picture, with a possible combination in any individual patient of axial disease, peripheral arthritis, enthesitis and dactylitis, psoriatic arthritis (PsA) is difficult to assess. Validated assessment tools for PsA are lacking. Recently, international study groups have a special interest in developing and validating standardized tools to assess PsA. We will review the existing assessment modalities of PsA focusing on axial disease, peripheral arthritis, enthesitis and dactylitis. Measures of function and disability recommended for PsA will be also reviewed
Identification of the Clinical Features Distinguishing Psoriatic Arthritis and Fibromyalgia
To identify the clinical features that can help to distinguish between psoriatic arthritis (PsA) and fibromyalgia (FM)

PTPN22 R620W polymorphism in the ANCA-associated vasculitides
Objectives. PTPN22 is involved in T-cell activation and its R620W single-nucleotide polymorphism ( SNP) has been shown to predispose to different autoimmune diseases. The aims of this study were to investigate the role of the PTPN22 R620W SNP in conferring susceptibility to the ANCA-associated vasculitides (AAVs), and to explore potential associations between the PTPN22 genotype and the disease manifestations.
Methods. PTPN22 R620W SNP was genotyped in a cohort of 344 AAV patients [143 with granulomatosis with polyangiitis (Wegener's) (GPA), 102 with microscopic polyangiitis (MPA) and 99 with Churg-Strauss syndrome (CSS)] and in 945 healthy controls.
Results. The frequency of the minor allele (620W) was significantly higher in GPA patients than in controls [P = 0.005, chi(2) = 7.858, odds ratio (OR) = 1.91], while no statistically significant association was found with MPA or CSS. Among GPA patients, the 620W allele was particularly enriched in ANCA-positive patients as compared with controls (P = 0.00012, chi(2) = 14.73, OR = 2.31); a particularly marked association was also found with ENT involvement (P = 0.0071, chi(2) = 7.258, OR = 1.98), lung involvement (P = 0.0060, chi(2) = 7.541, OR = 2.07) and skin manifestations of all kinds (P = 0.000047, chi(2) = 16.567, OR = 3.73).
Conclusion. The PTPN22 620W allele confers susceptibility to the development of GPA (but not of MPA or CSS), and particularly of its ANCA-positive subset
Tocilizumab in glucocorticoid-naive large-vessel vasculitis.
Glucocorticoids (GC) are the mainstay of treatment of large-vessel vasculitis (LVV), but a sizeable number of patients relapse upon tapering the GC dose or after discontinuation of GC therapy. In addition, GC cause numerous adverse events. Therefore, in patients with longstanding disease and in those at risk for GC-related adverse events, the use of alternative therapeutic agents should be considered. Interleukin-6 (IL-6) is a key player in the pathogenesis of LVV. Preliminary data suggest the efficacy of the IL-6 receptor inhibitor tocilizumab (TCZ) in patients with LVV. We report 2 treatment-na\uefve patients with a recent diagnosis of LVV who received monthly TCZ infusions (8 mg/kg body weight) for 6 consecutive months as monotherapy because of relative contraindications and patients' reluctance to take GC. In both cases we observed a complete clinical response and normalisation of inflammatory markers as well as a decrease in vascular FDG uptake and SUV ratio on fluorodeoxyglucose positron emission/computerised tomography. Serum IL-6 and soluble IL-6 receptor (sIL-6R) levels rose in both patients after TCZ therapy. TCZ may be an effective alternative to GC treatment for LVV patients at risk for GC-related adverse events. Larger studies are required to confirm our findings
