OBJECTIVE: There are no validated criteria to evaluate clinical response in juvenile idiopathic arthritis (JIA). The purpose of this study was to compare 4 sets of criteria (2 from the American College of Rheumatology [ACR] and 2 from the European League Against Rheumatism [EULAR]) for clinical response evaluation in JIA patients treated with methotrexate and/or anti-tumor necrosis factor alpha drugs. METHODS: Seventy-five patients with JIA were evaluated at baseline and after 6 months of therapy with second-line drugs. Mean age at study onset was 12.8 years (range 2-32.9 years). Diagnoses were systemic JIA (n = 16), rheumatoid factor-positive JIA (n = 5), rheumatoid factor-negative JIA (n = 9), persistent oligoarticular JIA (n = 10), extended oligoarticular JIA (n = 33), and psoriatic arthritis (n = 2). Clinical response was evaluated with the ACR Pediatric 30 criteria and the ACR 20% response criteria (ACR20), and with the EULAR Disease Activity Score (DAS) and 28-joint DAS (DAS28). Patients with EULAR criteria responses of 'good' or 'moderate' were classified as responders. Responders and nonresponders according to the different criteria were then compared. RESULTS: For patients younger than 16 years, Cohen's kappa varied between 0.51 and 0.72, with a good-to-excellent reproducibility index for all comparisons, except for the DAS28/ACR20 comparison. The best agreement was obtained by comparing the DAS and the ACR Pediatric 30. For patients older than 16 years, the reproducibility index was good or excellent in only 2 cases, i.e., comparing the DAS and the ACR Pediatric 30 and comparing the DAS and the DAS28 (as expected). CONCLUSION: Our study shows a good agreement overall for the different criteria tested. The highest concordance was observed between the DAS and the ACR Pediatric 30, the lowest between the DAS28 and the ACR20. Our data suggest that the ACR Pediatric 30 criteria can be used also in adult patients affected by JIA, and that the original DAS can be an alternative to the ACR Pediatric 30 in both children and young adults with JIA.

ObjectiveCross-reactivity with kidney antigens is believed to be a critical determinant in the renal pathogenicity of anti-double-stranded DNA (anti-dsDNA) antibodies. Murine nephritogenic anti-dsDNA antibodies have been shown to cross-react with alpha-actinin, and anti-alpha-actinin antibodies have been found to be deposited in the kidneys of lupus mice with active nephritis. Furthermore, in humans with systemic lupus erythematosus (SLE), it has been found that a greater proportion of polyclonal IgG anti-dsDNA antibodies from patients with renal involvement bind to alpha-actinin than do those from patients without renal disease. We undertook this study to substantiate a direct link between cross-reactive anti-dsDNA/anti-alpha-actinin antibodies and the pathogenesis of lupus nephritis in humans.MethodA panel of 10 anti-dsDNA and/or anti- alpha-actinin antibodies was generated by Epstein-Barr virus transformation of lymphocytes from patients with SLE and was extensively characterized. Antibody binding was studied by enzyme-linked immunosorbent assay and Western blotting. Antibody potential for pathogenicity was assessed by measuring binding to isolated glomeruli and mesangial cells and by evaluation of histologic features of the kidney following injection in vivo.ResultsAll anti-dsDNA antibodies isolated also bound alpha-actinin. Cross-reactive antibodies bound to mesangial cells and to isolated glomeruli ex vivo. Binding to glomeruli was not inhibited by DNase treatment, but could be abrogated by alpha-actinin. Furthermore, histopathologic abnormalities seen in mice injected intraperitoneally with a cross-reactive cell line included fusion of podocyte foot processes and subepithelial and subendothelial deposition.ConclusionThese studies provide strong support for the hypothesis that alpha-actinin is a major cross-reactive target for anti-dsDNA antibodies in SLE patients. Cross-reactive anti-dsDNA/anti-alpha-actinin antibodies from SLE patients are pathogenic and may contribute to the kidney lesions in lupus nephritis. [ABSTRACT FROM AUTHOR]

Objectives: To evaluate, in a multicentric Italian cohort of axial spondyloarthritis (axSpA) patients on Secukinumab (SEC) followed for 24 months: (1) the long-term effectiveness and safety of SEC; (2) the drug retention rate and low disease activity (LDA) measured as Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) < 4/Ankylosing Spondylitis Disease Activity Score (ASDAS) < 2.1 and very low disease activity (VLDA) measured as BASDAI < 2/ASDAS < 1.3; (3) any differences in outcomes according to line of biological treatment (naïve/non-naïve), gender (male/female), subtype of axSpA [radiographic axSpA (r-axSpA)/non-radiographic axSpA (nr-axSpA)]., Methods: Consecutive axSpA patients treated with SEC were evaluated prospectively. Disease characteristics, previous/ongoing treatments, comorbidities, and follow-up duration were collected. Disease activity/functional/clinimetric scores and biochemical-values were recorded at baseline (T0), 6 (T6), 12 (T12), and 24 (T24) months. Effectiveness was evaluated over-time with descriptive statistics; multivariate Cox and logistic regression models were used to evaluate predictors of drug discontinuation and LDA at T6. Infections and adverse events were recorded., Results: A total 249 patients (47.8% male; median age 51) were enrolled; 40.9% had HLA-B27; 53.8% had r-axSpA, and 46.2% nr-axSpA. SEC was prescribed in 28.9% naïve and in 71.1% non-naïve patients. SEC effectiveness was shown as an improvement in several outcomes, such as ASDAS [T0 = 3.5 (2.9-4.4) versus T24 = 1.9 (1.2-2.4); p  = 0.02] and BASDAI [T0 = 6.5 (5.0-7.5) versus T24 = 2.8 (1.8-4.0); p  = 0.03]. At T24, naïve patients showed better physical functioning and lower disease activity than non-naïve. After 24 months of treatment, 90.7% of naïve and 75.3% of non-naïve patients achieved LDA (BASDAI < 4). Treatment was discontinued in 24.5% patients, mainly due to primary/secondary loss of effectiveness, and in 6.8% due to adverse events. Retention rate at T24 was 75% in the whole population, with some difference depending on gender ( p  = 0.002)., Conclusion: In a real-life clinical setting, SEC proved to be safe and effective in axSpA, mainly in naïve-patients, with a notable drug retention rate.

Objective: The purpose of the ULISSE study was to evaluate the prevalence of clinical and ultrasonographic (US) entheseal involvement in patients with psoriatic arthritis (PsA), psoriasis, and fibromyalgia syndrome (FMS)., Methods: In this cross-sectional multicenter study, patients with PsA and psoriasis (not taking systemic therapy) and FMS underwent a clinical evaluation of the entheses, and a B-mode and power Doppler examination of 6 pairs of entheses., Results: The study analyzed 140 patients with PsA, 51 with psoriasis, and 51 with FMS. Clinical and US examinations were performed in 1960 and 1680 entheses in the PsA group, and 714 and 612 entheses both in the psoriasis group and in the FMS group. In both per-patient and per-enthesis evaluation, the frequency of entheseal tenderness was higher in patients with FMS (92% of the patients and 46% of the entheses, compared with 66%/23% in the PsA group and 59%/18% in the psoriasis group). With US examination, signs of entheseal involvement were more frequent in both the per-patient and per-enthesis evaluation in PsA and psoriasis (about 90% of patients in both the PsA and psoriasis groups and 75% of patients in the FMS group had at least 1 site affected, and 54%, 41%, and 27% of the pairs of entheses in, respectively, PsA, psoriasis, and FMS patients showed at least 1 enthesis involved)., Conclusion: The ULISSE study indicated that enthesitis is a common feature in patients with PsA, those with psoriasis, and in those with FMS if only clinical examination is used. US entheseal assessment showed findings more consistent with the 3 disorders.

Objective: Physician's global assessment (PGA) of disease activity is a major determinant of therapeutic decision making. This study assesses the reliability of the PGA, measured by means of 0-100 mm visual analog scale (VAS), and the additional use of separate VAS scales for musculoskeletal (PhysMSK) and dermatologic (PhysSk) manifestations in patients with psoriatic arthritis (PsA)., Methods: Sixteen centers from 8 countries enrolled 319 consecutive patients with PsA. PGA, PhysMSK, and PhysSk evaluation forms were administered at enrollment (W0) and after 1 week (W1). Detailed clinical data regarding musculoskeletal (MSK) manifestations, as well as dermatological assessment, were recorded., Results: Comparison of W0 and W1 scores showed no significant variation (intraclass correlation coefficients were PGA 0.87, PhysMSK 0.86, PhysSk 0.78), demonstrating the reliability of the instrument. PGA scores were dependent on PhysMSK and PhysSk (p < 0.0001) with a major effect of the MSK component (B = 0.69) compared to skin (B = 0.32). PhysMSK was correlated with the number of swollen joints, tender joints, and presence of dactylitis (p < 0.0001). PhysSk scores were correlated with the extent of skin psoriasis and by face, buttocks or intergluteal, and feet involvement (p < 0.0001). Finally, physician and patient assessments were compared showing frequent mismatch and a scattered dot plot: PGA versus patient's global assessment (r = 0.36), PhysMSK versus patient MSK (r = 0.39), and PhysSk versus patient skin (r = 0.49)., Conclusion: PGA assessed by means of VAS is a reliable tool to assess MSK and dermatological disease activity. PGA may diverge from patient self-evaluation. Because MSK and skin/nail disease activity may diverge, it is suggested that both PhysMSK and PhysSk are assessed.

Objective: During OMERACT 8, delegates selected patient global assessment (PGA) of disease as a domain to be evaluated in randomized controlled trials in psoriatic arthritis (PsA). This study assessed the reliability of the PGA, measured by means of 0-100 mm visual analog scale (VAS), and the additional utility of separate VAS scales for joints (PJA) and skin (PSA)., Methods: In total, 319 consecutive patients with PsA (186 men, 133 women, mean age 51 ± 13 yrs) were enrolled. PGA, PJA, and PSA were administered at enrolment (W0) and after 1 week (W1). Detailed clinical data, including ACR joint count, Psoriasis Area and Severity Index (PASI), and Hospital Anxiety and Depression Scale, were recorded., Results: Comparison of W0 and W1 scores showed no significant variations (intraclass correlation coefficients for PGA 0.87, PJA 0.86, PSA 0.78), demonstrating the reliability of the instrument. PGA scores were not influenced by patient anxiety or depression, but were dependent on PJA and PSA (p = 0.00001). PJA was dependent on the number of swollen and tender joints (p < 0.00001). PSA scores were influenced by the extent of skin psoriasis and by hand skin involvement (p = 0.00001). Joint and skin disease were found not to correlate in terms of disease activity as evidenced by the swollen joint count compared to PASI (r = 0.11) and by the PJA compared to PSA (r = 0.38)., Conclusion: PGA assessed by means of VAS is a reliable tool related to joint and skin disease activity. Because joint and skin disease often diverge it is suggested that in some circumstances both PJA and PSA are also assessed.

Objective: The purpose of this study was to evaluate the long-term survival rate of Methotrexate (MTX) in the peripheral joint involvement of psoriatic arthritis (PsA) in a setting of everyday clinical practice., Methods: This was an observational restrospective study performed using the data from a dermatological-rheumatological PsA clinic. All of the patients evaluated at this clinic from March 1997 to December 2007 who were started on MTX alone, had a three-year follow-up time or had discontinued the therapy were included into the survey., Results: Of the 174 evaluable patients, 104 (59.8%) were still taking MTX after three years of treatment. The reasons of therapy discontinuation in the remaining 70 (40.2%) patients were: 34 (19.5%) lost-to-follow-up, 18 (10.3%) adverse events, 14 (8%) inefficacies, and 4 (2.3%) deaths (none related to the therapy). MTX was effective in controlling joint inflammation but not in preventing their deterioration. Overall, adverse events were recorded in 43 patients (36.4% of the 114 patients with a three-year follow-up). No serious side effect occurred in the study population., Conclusions: The results of this study showed that, in a setting of clinical pratice, MTX had a good three-year performance in patients with peripheral PsA. Almost 60% of them were still taking this drug at the end of the study period and the toxicity was more than acceptable. In our opinion, MTX might be considered the non-biological DMARD of choice for the treatment of this condition. However it should be used earlier and at higher doses.

The objective was to estimate the incidence of serious infections in the patients treated with anti-TNFalpha agents for rheumatoid arthritis (RA) recorded in the Lombardy Rheumatology Network (LORHEN) registry. The study inclusion criteria were met by 1064 of the 1114 patients with long-standing RA, 519 treated with infliximab, 303 with adalimumab, and 242 with etanercept; their mean age was 55.8 years and the mean duration of RA 9.4 years. Seventy-three patients (6.9%) experienced a total of 74 serious infections, an incidence rate for all treatment courses of 35.9 per 1000 patient-years (95% confidence interval [95% CI] 27.66-44.13). Most were lower respiratory tract (34.2%) or skin and soft tissue infections (20.5%). Of the 1064 patients, the 790 treated with anti-TNFalpha after March 2002 underwent screening tests for LTBI; five patients developed active tuberculosis. Three patients died of septic shock. The type of anti-TNFalpha agent did not seem to affect the incidence or site of the infections. Both univariate and multivariate analyses identified age at the start of anti-TNFalpha treatment (p=0.008), baseline erythrocyte sedimentation rate ([ESR] p=0.014), and the concomitant use of corticosteroids (p=0.029) as significant predictors of infections. There was no statistically significant difference in risk between the anti-TNFalpha agents.
