Effectiveness and safety of secukinumab in axial spondyloarthritis: a 24-month prospective, multicenter real-life study.

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. No differences were observed between r-axSpA and nr-axSpA.

Ultrasonographic and Clinical Assessment of Peripheral Enthesitis in Patients with Psoriatic Arthritis, Psoriasis, and Fibromyalgia Syndrome: The ULISSE Study.

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.

Physician's Global Assessment in Psoriatic Arthritis: A Multicenter GRAPPA Study.

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.

Patient global assessment in psoriatic arthritis: a multicenter GRAPPA and OMERACT study.

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.

Serious infections during anti-TNFalpha treatment in rheumatoid arthritis patients.

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.

Efficacy of repeated intravenous infusions of an anti-tumor necrosis factor alpha monoclonal antibody, infliximab, in persistently active, refractory juvenile idiopathic arthritis: results of an open-label prospective study.

OBJECTIVE: To evaluate the efficacy and safety of a chimeric monoclonal anti-tumor necrosis factor alpha antibody (infliximab) with methotrexate (MTX) in juvenile idiopathic arthritis (JIA) with an active polyarticular course that is not responsive to MTX. METHODS: Twenty-four young adults with long-lasting, refractory JIA were enrolled in an open, prospective, 2-year pilot study. Patients received intravenous infliximab at 3 mg/kg of body weight at weeks 0, 2, and 6 and every 8 weeks thereafter, with weekly subcutaneous MTX. RESULTS: The median duration of therapy was 9.1 months. Significant improvements were observed in the number of joints (28-joint count) with active disease (median 6 at baseline, 2 at 2 weeks, 0 at 6 months, 0 at 1 year; P < 0.05). Pain as well as patient's and physician's global assessments of disease status were assessed on 0-100-mm (0 = best; 100 = worst) visual analog scales (VAS). There were significant improvements in VAS pain scores (45 at baseline, 25 at 2 weeks, 8.5 at 6 months, 10 at 1 year; P < 0.05), patient's global assessment of disease status (50 at baseline, 22 at 2 weeks, 11.5 at 6 months, 18 at 1 year; P < 0.05), and physician's global assessment of disease status (50.5 at baseline, 22.5 at 2 weeks, 6.5 at 6 months, 10 at 1 year; P < 0.01). In addition, there were significant improvements in the erythrocyte sedimentation rate (64 mm/hour at baseline, 36 mm/hour at 2 weeks, 23.5 mm/hour at 6 months, 35 mm/hour at 1 year; P < 0.01) and C-reactive protein level (4.9 mg/dl at baseline, 2.8 mg/dl at 2 weeks, 3.1 mg/dl at 6 months, 3.2 mg/dl at 1 year; P < 0.005). The percentage of patients meeting the American College of Rheumatology 20% improvement criteria at each assessment ranged from 54.2% to 86.7%. Of the responses on the Disease Activity Score in 28 joints, 37.5-63.6% were classified as "good," 14.3-33.3% were classified as "moderate," and 18-37.5% were classified as "no response." Twelve patients (50%) had adverse events, and 5 patients (20.8%) withdrew. CONCLUSION: Infliximab plus MTX showed high effectiveness and safety in short- and medium-term treatment of long-lasting refractory JIA. A controlled multicenter clinical trial is needed.
