ObjectiveTo update the European League Against Rheumatism (EULAR) recommendations for the pharmacological treatment of psoriatic arthritis (PsA).MethodsAccording to the EULAR standardised operating procedures, a systematic literature review was followed by a consensus meeting to develop this update involving 28 international taskforce members in May 2019. Levels of evidence and strengths of recommendations were determined.ResultsThe updated recommendations comprise 6 overarching principles and 12 recommendations. The overarching principles address the nature of PsA and diversity of both musculoskeletal and non-musculoskeletal manifestations; the need for collaborative management and shared decision-making is highlighted. The recommendations provide a treatment strategy for pharmacological therapies. Non-steroidal anti-inflammatory drugs and local glucocorticoid injections are proposed as initial therapy; for patients with arthritis and poor prognostic factors, such as polyarthritis or monoarthritis/oligoarthritis accompanied by factors such as dactylitis or joint damage, rapid initiation of conventional synthetic disease-modifying antirheumatic drugs is recommended. If the treatment target is not achieved with this strategy, a biological disease-modifying antirheumatic drugs (bDMARDs) targeting tumour necrosis factor (TNF), interleukin (IL)-17A or IL-12/23 should be initiated, taking into account skin involvement if relevant. If axial disease predominates, a TNF inhibitor or IL-17A inhibitor should be started as first-line disease-modifying antirheumatic drug. Use of Janus kinase inhibitors is addressed primarily after bDMARD failure. Phosphodiesterase-4 inhibition is proposed for patients in whom these other drugs are inappropriate, generally in the context of mild disease. Drug switches and tapering in sustained remission are addressed.ConclusionThese recommendations provide stakeholders with an updated consensus on the pharmacological management of PsA, based on a combination of evidence and expert opinion.
Introduction The objective was to develop a questionnaire that can be used to calculate a score reflecting the impact of psoriatic arthritis (PsA) from the patients' perspective: the PsA Impact of Disease (PsAID) questionnaire. Methods Twelve patient research partners identified important domains (areas of health); 139 patients prioritised them according to importance. Numeric rating scale (NRS) questions were developed, one for each domain. To combine the domains into a single score, relative weights were determined based on the relative importance given by 474 patients with PsA. An international cross-sectional and longitudinal validation study was performed in 13 countries to examine correlations of the PsAID score with other PsA or generic disease measures. Test-retest reliability and responsiveness (3 months after a treatment change) were examined in two subsets of patients. Results Two PsAID questionnaires were developed with both physical and psychological domains: one for clinical practice (12 domains of health) and one for clinical trials (nine domains). Pain, fatigue and skin problems had the highest relative importance. The PsAID scores correlated well with patient global assessment (N=474, Spearman r=0.82-0.84), reliability was high in stable patients (N=88, intraclass correlation coefficient=0.94-0.95), and sensitivity to change was also acceptable (N=71, standardised response mean=0.90-0.91). Conclusions A questionnaire to assess the impact of PsA on patients' lives has been developed and validated. Two versions of the questionnaire are available, one for clinical practice (PsAID-12) and one for clinical trials (PsAID-9). The PsAID questionnaires should allow better assessment of the patient's perspective in PsA. Further validation is needed
Objective A patient-derived composite measure of the impact of rheumatoid arthritis (RA), the rheumatoid arthritis impact of disease (RAID) score, takes into account pain, functional capacity, fatigue, physical and emotional wellbeing, quality of sleep and coping. The objectives were to fi nalise the RAID and examine its psychometric properties. Methods An international multicentre cross-sectional and longitudinal study of consecutive RA patients from 12 European countries was conducted to examine the psychometric properties of the different combinations of instruments that might be included within the RAID combinations scale (numeric rating scales (NRS) or various questionnaires). Construct validity was assessed cross-sectionally by Spearman correlation, reliability by intraclass correlation coeffi cient (ICC) in 50 stable patients, and sensitivity to change by standardised response means (SRM) in 88 patients whose treatment was intensifi ed. Results 570 patients (79% women, mean±SD age 56±13 years, disease duration 12.5±10.3 years, disease activity score (DAS28) 4.1±1.6) participated in the validation study. NRS questions performed as well as longer combinations of questionnaires: the fi nal RAID score is composed of seven NRS questions. The fi nal RAID correlated strongly with patient global (R=0.76) and signifi cantly also with other outcomes (DAS28 R=0.69, short form 36 physical −0.59 and mental −0.55, p<0.0001 for all). Reliability was high (ICC 0.90; 95% CI 0.84 to 0.94) and sensitivity to change was good (SRM 0.98 (0.96 to 1.00) compared with DAS28 SRM
Background: Current response criteria in rheumatoid arthritis (RA) usually assess only three patient-reported outcomes (PROs): pain, functional disability and patient global assessment. Other important PROs such as fatigue are not included. Objective: To elaborate a patient-derived composite response index for use in clinical trials in RA, the RA Impact of Disease (RAID) score. Methods: Ten patients identified 17 domains or areas of health relevant for inclusion in the score, then 96 patients (10 per country in 10 European countries) ranked these domains in order of decreasing importance. The seven most important domains were selected. Instruments were chosen for each domain after extensive literature research of psychometric properties and expert opinion. The relative weight of each of the domains was obtained from 505 patients who were asked to ''distribute 100 points'' among the seven domains. The average ranks of importance of these domains were then computed.
Objective. CXCL10 (also known as interferon-␥-inducible 10-kd protein [IP-10]) is a chemokine that potentially plays a role in the immunopathogenesis of rheumatoid arthritis (RA). We undertook this phase II study to evaluate the efficacy and safety of MDX-1100, a fully human, anti-CXCL10 (anti-IP-10) monoclonal antibody, in RA patients whose disease responded inadequately to methotrexate (MTX).Methods. Patients with active RA receiving stable doses of MTX (10-25 mg weekly) were randomized to receive intravenous doses of 10 mg/kg MDX-1100 (n ؍ 35) or placebo (n ؍ 35) every other week. The primary end point was the proportion of patients meeting the American College of Rheumatology 20% improvement criteria (achieving an ACR20 response) on day 85, and patients were followed up for safety to day 141.Results. The ACR20 response rate was significantly higher among MDX-1100-treated patients than among placebo-treated patients (54% versus 17%; P ؍ 0.0024). Statistically significant differences in the ACR20 response rate between treatments were observed starting on day 43 (P < 0.05). The ACR50 and ACR70 response rates on day 85 did not differ between the groups. Overall, 51
Objective: Vitamin D has pleiotropic effects including immunomodulatory, cardioprotective, and antifibrotic properties and is thus able to modulate the three main links in scleroderma pathogenesis. The aim of the study was to evaluate the level of vitamin D in patients with systemic sclerosis and to analyze the associations between the concentration of vitamin D and the features of systemic sclerosis.Material and Methods: Fifty-one consecutive patients were evaluated for visceral involvement, immunological profile, activity, severity scores, and quality of life. The vitamin D status was evaluated by measuring the 25hydroxy-hydroxyvitamin D serum levels.
Results:The mean vitamin D level was 17.06±9.13 ng/dL. Only 9.8% of the patients had optimal vitamin D levels; 66.66% of them had insufficient 25(OH)D levels, while 23.52% had deficient levels. No correlation was found between vitamin D concentration and age, sex, autoantibody profile, extent of skin involvement, or vitamin D supplementation. Vitamin D levels were correlated with the diffusing capacity of the lung for carbon monoxide (p=0.019, r=0.353), diastolic dysfunction (p=0.033, r=−0.318), digital contractures (p=0.036, r=−0.298), and muscle weakness (p=0.015, r=−0.377) and had a trend for negative correlation with pulmonary hypertension (p=0.053, r=−0.29).Conclusion: Low levels of vitamin D are very common in systemic sclerosis. Poor vitamin status seems to be related with a more aggressive disease with multivisceral and severe organ involvement, especially pulmonary and cardiac involvement.
