Abstract

Alberto Cauli, Giovanni Porru, Matteo Piga, Alessandra Vacca, Grazia Dessole, Alessandro MathieuRheumatology Unit, Department of Medical Sciences, Policlinico of University of Cagliari, Monserrato, ItalyAbstract: Psoriatic arthritis (PsA) is a frequent chronic inflammatory disease characterized by joint and skin involvement, and by typical extra-articular manifestations. Although the pathogenesis of PsA is still under investigation, the available evidence suggests the importance of the patient's genetic background, microbial or environmental triggers, and an imbalance in the adaptive and acquired immune system, resulting in the production of inflammatory mediators. New therapeutic approaches have been proposed, among them the use of modulators of intracellular signals and gene transcription such as PDE4-inhibiting compounds, which are able to modulate the activity of transcription factors such as CREB and NF-κB and therefore the synthesis of inflammatory mediators, resulting in immunoregulation. This paper summarizes the mechanism of action of apremilast, a PDE4 inhibitor, and the clinical data available on its clinical efficacy and safety profile in the treatment of PsA patients.Keywords: psoriatic arthritis, apremilast, therapy

Abstract

Objective: To compare drug survival of different anti-TNF drugs (inliximab, INF, etanercept, ETA, and adalimumab, ADA) in rheumatoid arthritis (RA) and spondyloarthritis (SpA) by analysing data collected from an Italian multicentre observational cohort study.Methods: All patients with RA or SpA registered in the MonitorNet database who started their irst course of anti-TNF therapy were included.Overall drug survival was measured, along with speciic reasons of discontinuation (ineficacy or adverse events).A first set of analyses using RA as reference category assessed the relationship between diagnosis and drug survival.A second set of analyses stratiied by diagnosis (RA and SpA) used INF as reference drug.Adjustment for confounders was performed.The results are presented as adjusted hazard ratios (adjHR) and 95% conidence intervals (95%CI).Results: 2640 RA patients and 1220 SpA patients with a median follow-up of 17 months (IQR 7.2-33.4) were included in the analyses.Patients with a diagnosis of SpA showed a lower risk of drug discontinuation with an adjHR (95%CI) of 0.81 (0.73, 0.90).In SpA, the subset of patients with ankylosing spondylitis (AS) showed the best survival on treatment.In RA, both ETA and ADA showed a signiicantly lower probability of withdrawal when compared to INF [adjHR (95%CI) 0.46 (0.38, 0.56) and 0.68 (0.57, 0.81), respectively].Similar results were found in SpA.Conclusion: Drug survival for SpA is longer than that in RA mainly due to the AS subgroup.In both RA and SpA, ETA and ADA showed a better retention on treatment when compared to INF.

Abstract

Item does not contain fulltext, OBJECTIVE: To develop new composite disease activity indices for psoriatic arthritis (PsA). METHODS: Data from routine clinic visits at multiple centres were collected in a systematic manner. Data included all domains identified as important in randomised controlled trials in PsA. Decisions to change treatment were used as surrogates for high disease activity. New indices were developed by multiple linear regression (psoriatic arthritis disease activity score: PASDAS) and empirically, utilising physician-defined cut-offs for disease activity (arithmetic mean of desirability functions: AMDF). These were compared with existing composite measures: Composite Psoriatic arthritis Disease Activity Index (CPDAI), Disease Activity for PSoriatic Arthritis (DAPSA), and Disease Activity Score for rheumatoid arthritis (DAS28). RESULTS: 161/503 (32%) subjects had treatment changes. Although all measures performed well, compared with existing indices, PASDAS was better able to discriminate between high and low disease activity (area under receiver operating curves (ROC)) curve with 95% CI: PASDAS 0.773 (0.723, 0.822); AMDF 0.730 (0.680, 0.780); CPDAI 0.719 (0.668, 0.770); DAPSA 0.710 (0.654, 0.766); DAS28 0.736 (0.680, 0.792). All measures were able to discriminate between disease activity states in patients with oligoarthritis, although area under the receiver operating curves (AUC) were generally smaller. In patients with severe skin disease (psoriasis area and severity index >10) both nonparametric and AUC curve statistics were nonsignificant for all measures. CONCLUSIONS: Two new composite measures to assess disease activity in PsA have been developed. Further testing in other datasets, including comparison with existing measures, is required to validate these instruments.

Abstract

We investigate minimization and maximization of the principal eigenvalue of the Laplacian under mixed boundary conditions in case the weight has indefinite sign and varies in a class of rearrangements. Biologically, these optimization problems are motivated by the question of determining the most convenient spatial arrangement of favorable and unfavorable resources for a species to survive or to decline. We prove existence and uniqueness results, and present some features of the optimizers. In special cases, we prove results of symmetry and results of symmetry breaking for the minimizer.

Abstract

Interferons (IFN) are well known triggers of immunomediated diseases in genetically predisposed subjects. We describe the unique case of a HLA-B*2709 positive subject who underwent IFN-alpha treatment for essential thrombocythemia and developed arthritis of the proximal interphalangeal joints of the hands but not sacroiliitis. The possible mechanisms of IFN-induced arthritis are discussed.

Abstract

Objective.To identify the clinical features that can help to distinguish between psoriatic arthritis (PsA) and fibromyalgia (FM).Methods.Our cross-sectional study was carried out in 10 Italian rheumatology centers between January and September 2009, and enrolled all consecutive patients with PsA and FM who agreed to participate. Standard clinical and laboratory data for PsA and FM were collected from all patients. Records were made of somatic symptoms, response to nonsteroidal antiinflammatory drugs (NSAID), self-evaluated pain, general health, disability, and responses to the Fibromyalgia Impact Questionnaire. Data were statistically analyzed by univariate and multivariate analyses, and receiver-operating characteristic curves. The analysis concentrated on the clinical features shared by the 2 conditions.Results.Two hundred sixty-six patients with PsA (mean age 51.7 yrs; disease duration 10.2 yrs) and 120 patients with FM (mean age 50.2 yrs; disease duration 5.6 yrs) were evaluated. Univariate analysis showed that patients with FM had higher mean tender point and enthesitis scores, more somatic symptoms, and responded less to NSAID. Multivariate analysis showed that the presence of ≥ 6 FM-associated symptoms and ≥ 8 tender points was the best predictor of FM.Conclusion.The shared clinical features of PsA and FM that had the greatest discriminating power for FM were the number of FM-associated symptoms and tender point count.

Abstract

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.

Abstract

OBJECTIVE: TNF-alpha antagonists, infliximab (INF), etanercept (ETA) and adalimumab (ADA), have been demonstrated to be effective in controlling symptoms in SpAs. The aim of this study was to investigate the possibility of using ADA as a second or third choice. METHODS: A retrospective study was conducted in patients with SpA treated with TNF-alpha blockers who switched from INF or ETA to ADA, for inefficacy or adverse events. Kaplan-Meier survival curves were plotted to determine the rates of continuation of the first treatment (INF or ETA) as compared with the rates of continuation of the second or third treatment with ADA. RESULTS: A total of 1619 patients with SpA were treated with INF (35.3%), ETA (43.7%) and ADA (20.9%). In this cohort, ADA was started in 38 (2.34%) patients as a second anti-TNF-alpha drug and in 9 (0.56%) as a third anti-TNF-alpha drug. In SpA patients who failed the first anti-TNF-alpha, for whatever reason, survival curves for ADA (as a second anti-TNF-alpha) were significantly better than survival curves for these same patients on their first anti-TNF-alpha (overall: P < 0.0001; INF: P < 0.0011; ETA: P < 0.02). CONCLUSION: Our retrospective study, resulting from real-life experience, showed that SpA patients who fail to respond to a first agent, INF or ETA, respond to ADA as a second-line drug regardless of the reason for switching
