Patterns of peripheral joint involvement in psoriatic arthritis-Symmetric, ray and/or row?

ABSTRACT: OBJECTIVE:We sought to examine whether joint involvement in psoriatic arthritis (PsA) follows a symmetric, ray, and/or row pattern using longitudinal data. METHODS:Data on activity and clinical damage of the joints of the hands and feet were obtained from a PsA cohort. For each analysis (symmetry, ray or row) for each outcome (joint damage and activity) expected values for table cells under the null hypothesis that joints progress independently to damage or activity were calculated based on a logistic regression model with patient level random effects for the probability of involvement developing between clinic visits. To determine the consistency of observed with expected values, goodness-of-fit tests were performed. RESULTS:Data from 704 patients were available. The 511 (552) patients with no hand (foot) damage at clinic entry were used for analyses of hand (foot) damage. When considering joint damage, there was strong evidence against independence of joint involvement based on evident symmetric patterns. There was little suggestion of ray patterns of joint damage. There was considerable evidence for row pattern of involvement of joints. When considering joint activity, symmetric patterns were also evident but, unlike joint damage, there was evidence of ray patterns, most notably in the hands. There was also evidence for row pattern involvement. CONCLUSION:Patterns of peripheral joint involvement seen over time in PsA patients, demonstrate consistency with expected ray patterns of disease activity, especially in the hands, but there is also considerable evidence for symmetric and row patterns for both joint damage and activity.

Project description:IntroductionPsoriatic arthritis (PsA) is a chronic, systemic, inflammatory disease where disease burden and quality of life (QoL) are affected by both joint and skin manifestations.MethodsPatient and physician reported data were collected about 3200 patients in a cross-sectional survey of patients from nine countries. Patient-reported outcomes (PROs) included perceptions of symptom importance, EuroQol questionnaire (EQ-5D), Psoriatic Arthritis Impact of Disease (PsAID12), and Work Productivity and Activity Impairment (WPAI) Index. Outcomes were compared in patients with 'joint-only' and 'joint and skin' disease symptoms.ResultsOf the 3200 patients, 2703 had complete information for 'joint-only' or 'joint and skin' involvement and were included in the analysis. Patients had a mean age of 49.2 years, 45.2% were female, and 64.5% had 'joint and skin' involvement. Patients with 'joint and skin' involvement had higher mean tender and swollen joint counts (5.2 and 4.8) than patients who were 'joint-only' (2.0 and 1.5). Significantly more patients with active 'joint and skin' symptoms experienced a flare (currently or within the last 12 months) compared with 'joint-only' patients (34.9 vs. 23.2%, p < 0.001). When asked to prioritize the burden of symptoms, 61.6% of patients prioritized joints, 38.4% prioritized skin. Anxiety/depression was experienced by 41.4% of patients, 62.4% of whom indicated that both joint and skin symptoms were the cause. Patients with 'joint and skin' involvement reported significantly worse QoL, work productivity and activity impairment than 'joint-only' patients (EQ-5D index 0.79 vs. 0.85, p < 0.001; EQ-5D VAS 71.98 vs. 77.68, p < 0.001; PsAID12 2.91 vs. 1.66, p < 0.001; WPAI overall work impairment 25.61 vs. 16.32, p < 0.001).ConclusionsPsA patients who experience 'joint and skin' symptoms had significantly worse clinical outcomes, health-related QoL, and work productivity compared with patients with 'joint-only' symptoms.

Project description:BackgroundInvolvement of the axial skeleton (sacroiliac joints and spine) is a relatively frequent manifestation associated with psoriatic skin disease, mostly along with involvement of peripheral musculoskeletal structures (peripheral arthritis, enthesitis, dactylitis), which are referred to as psoriatic arthritis (PsA). Data suggest that up to 30% of patients with psoriasis have PsA. Depending on the definition used, the prevalence of axial involvement varies from 25% to 70% of patients with PsA. However, there are currently no widely accepted criteria for axial involvement in PsA.Objective: The overarching aim of the Axial Involvement in Psoriatic Arthritis (AXIS) study is to systematically evaluate clinical and imaging manifestations indicative of axial involvement in patients with PsA and to develop classification criteria and a unified nomenclature for axial involvement in PsA that would allow defining a homogeneous subgroup of patients for research.DesignProspective, multicenter, multinational, cross-sectional study.Methods and analysesIn this multicenter, multinational, cross-sectional study, eligible patients [adult patients diagnosed with PsA and fulfilling Classification Criteria for Psoriatic Arthritis (CASPAR) with musculoskeletal symptom duration of ⩽10 years not treated with biological or targeted synthetic disease-modifying anti-rheumatic drugs] will be recruited prospectively. They will undergo study-related clinical and imaging examinations. Imaging will include radiography and magnetic resonance imaging examinations of sacroiliac joints and spine. Local investigators will evaluate for the presence of axial involvement based on clinical and imaging information which will represent the primary outcome of the study. In addition, imaging will undergo evaluation by central review. Finally, the central clinical committee will determine the presence of axial involvement based on all available information.EthicsThe study will be performed according to the ethical principles of the Declaration of Helsinki and International Council for Harmonisation Good Clinical Practice guidelines. The study protocol will be approved by the individual Independent Ethics Committee / Institutional Review Board of participating centers. Written informed consent will be obtained from all included patients.Registration: ClinicalTrials.gov ID: NCT04434885.
