RESUMO
Nearly half of all stars similar to our Sun are in binary or multiple systems1, which may affect the evolution of the stars and their protoplanetary disks during their earliest stages. NGC 1333-IRAS2A is a young, Class 0, low-mass protostellar system located in the Perseus molecular cloud2. It is known to drive two bipolar outflows that are almost perpendicular to each other on the sky3,4 and is resolved into binary components, VLA1 and VLA2, through long wavelength continuum observations5. Here we report spatially and spectrally resolved observations of a range of molecular species. We compare these to detailed magnetohydrodynamic simulations: the comparisons show that inhomogeneous accretion onto the circumstellar disks occurs in episodic bursts, driving a wobbling jet. We conclude that binarity and multiplicity in general strongly affect the properties of the emerging stars, as well as the physical and chemical structures of the protoplanetary disks and therefore potentially any emerging planetary systems.
RESUMO
OBJECTIVES: To explore the prognostic value of pre-specified comorbidities on treatment outcomes in PsA, and to compare baseline data with cutaneous psoriasis without arthritis and healthy controls (HC). METHODS: Patients initiating conventional synthetic/biological disease-modifying antirheumatic drugs were enrolled in this clinical observational cohort study, and data on comorbidities, and clinical and patient-reported outcomes were retrieved at baseline and after 4 months. Pearson's chi-squared tests were performed to investigate the prognostic value of pre-specified comorbidities and achievement of ACR20, DAPSA50 and MDA. Mann-Whitney U tests were used to compare OMERACT PsA Core Outcome Set (COS) measures at baseline and follow-up for the pre-specified comorbidities. RESULTS: A total of 100 PsA patients were included at baseline. Statistically significantly fewer patients with obesity achieved DAPSA50 compared with patients without obesity (P =0.035), and fewer patients with hypertension (P =0.034) and Charlson Comorbidity Index (CCI) ≥1 (P =0.027), respectively, achieved MDA compared with patients without these comorbidities. Patients with obesity, hypertension, widespread pain, and CCI ≥1 had significantly worse COS measures at follow-up compared with patients without these comorbidities. At baseline, patients with PsA had higher disease burden compared with patients with cutaneous psoriasis and HC, including higher pain (P <0.001) and fatigue (P <0.001) scores, and more widespread pain (P =0.002). CONCLUSION: Obesity, hypertension and CCI ≥1 were prognostic factors for poorer treatment outcome rates in PsA. Pain and fatigue were more frequently reported among patients with PsA compared with patients with cutaneous psoriasis and HC.

OBJECTIVES: Weight loss is commonly recommended for gout, but the magnitude of the effect has not been evaluated in a systematic review. The aim of this systematic review was to determine benefits and harms associated with weight loss in overweight and obese patients with gout. METHODS: We searched six databases for longitudinal studies, reporting the effect of weight loss in overweight/obese gout patients. Risk of bias was assessed using the tool Risk of Bias in Non-Randomised Studies of Interventions. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation. RESULTS: From 3991 potentially eligible studies, 10 were included (including one randomised trial). Interventions included diet with/without physical activity, bariatric surgery, diuretics, metformin or no intervention. Mean weight losses ranged from 3 kg to 34 kg. Clinical heterogeneity in study characteristics precluded meta-analysis. The effect on serum uric acid (sUA) ranged from -168 to 30 µmol/L, and 0%-60% patients achieving sUA target (<360 µmol/L). Six out of eight studies (75%) showed beneficial effects on gout attacks. Two studies indicated dose-response relationship for sUA, achieving sUA target and gout attacks. At short term, temporary increased sUA and gout attacks tended to occur after bariatric surgery. CONCLUSIONS: The available evidence is in favour of weight loss for overweight/obese gout patients, with low, moderate and low quality of evidence for effects on sUA, achieving sUA target and gout attacks, respectively. At short term, unfavourable effects may occur. Since the current evidence consists of a few studies (mostly observational) of low methodological quality, there is an urgent need to initiate rigorous prospective studies (preferably randomised controlled trials).

Objective: The aim was to assess work-loss days before and after commencement of anti-TNF treatment in patients with non-radiographic axial spondylarthritis (nr-axSpA). Methods: Bionaïve nr-axSpA patients (n = 75), aged 17-62 years, fulfilling the Assessment of SpondyloArthritis international Society criteria for axial spondyloarthritis and starting anti-TNF treatment during 2004-11, were retrieved from the observational South Swedish Arthritis Treatment Group study. Patient information was linked to Swedish Social Insurance Agency data on sick leave and disability pension from 1 year before to 2 years after anti-TNF initiation. Matched population references were included for comparison and to adjust for secular trends. Results: The nr-axSpA patients had a median age of 35 years and disease duration of 6 years at the start of treatment. During the 2 years after anti-TNF initiation, mean work-loss days (including both sick leave and disability pension) in the nr-axSpA group decreased significantly from 3.4 to 1.9 times more than among the population references. The effect was seen on sick leave, whereas disability pension levels remained similar in both groups throughout. Conclusion: Anti-TNF therapy in nr-axSpA was associated with a significant and sustained improvement of work disability over 2 years. However, the proportion of work-loss days remained almost twice as high as in the general population at the end of follow-up.

BACKGROUND: Several biologics targeting the Th17 pathway have been developed for the treatment of psoriatic arthritis (PsA), a disabling disease with moderate response and an increased incidence of serious infections to first-line biologics (TNF-α antagonists). Th17 inhibitors could replace TNF-α antagonists as first-line biologic agents. We determined the overall treatment effect of Th17 pathway inhibitors compared to placebo or active control on American College of Rheumatology (ACR) 20 response at week 12 (primary objective), risk of infections, discontinuation of treatment due to adverse events, and serious adverse events during the placebo-controlled period (12-24 weeks) in adults with active PsA in published randomized controlled trials. METHODS: The SCOPUS database was searched. The Cochrane risk of bias tool was used for assessing quality. The pooled relative risk (RR) was derived from random effects models. RESULTS: Seven randomized controlled trials were included which randomized 1,718 patients to Th17 inhibitors and 840 to placebo. Patients treated with Th17 inhibitors had an RR of 2.04 (95% CI: 1.79-2.33; p < 0.001) for achieving an ACR20 response at week 12 (I2 = 0%; p = 0.89) compared to placebo-treated patients. There was no evidence of publication bias. The result was consistent for study phase and outcome (ACR50/70), mechanism of action and TNF-α naivety. RR of infections was 1.06 (0.91-1.23), that of candida infections was 3.35 (0.75-14.95), that of serious adverse events was 0.82 (0.42-1.59) and that of discontinuation of treatment was 0.54 (0.31-0.93) among treated versus placebo subjects. No incident cases of tuberculosis were reported. CONCLUSION: In patients with active PsA, biologics targeting the Th17 axis produce a clinically significant improvement in joint disease activity with acceptable safety and tolerability for short-term treatment compared to placebo.

Background: Tofacitinib is a Janus kinase inhibitor for the treatment of psoriatic arthritis (PsA) and has been investigated for psoriasis (PsO). Objectives: This post hoc analysis examined baseline cardiovascular (CV) disease risk and its association with the occurrence of major adverse cardiovascular events (MACE) and malignancies in tofacitinib-treated patients with PsA and PsO. Design: Included three phase III/long-term extension (LTE) PsA trials and seven phase II/phase III/LTE PsO trials of patients receiving ⩾ 1 dose of tofacitinib. Methods: Incidence rates (IRs: patients with events/100 patient-years) for MACE and malignancies (excluding non-melanoma skin cancer) were determined in subgroups according to history of atherosclerotic CV disease (ASCVD), baseline 10-year risk of ASCVD (in patients without history of ASCVD), and baseline metabolic syndrome (MetS). Results: For patients with PsA (N = 783) and PsO (N = 3663), respectively, tofacitinib exposure was 2038 and 8950 patient-years (median duration: 3.0 and 2.4 years), and 40.9% and 32.7% had MetS. Excluding missing CV risk profile data, 51/773 (6.6%) and 144/3629 (4.0%) patients had history of ASCVD, and in patients without history of ASCVD, around 20.0% had intermediate/high baseline 10-year ASCVD risk. For PsA and PsO, IRs of MACE were greatest in those with history of ASCVD or high baseline 10-year ASCVD risk. For PsA, five of six patients with MACE had baseline MetS. Malignancy IRs in patients with PsA were greatest in those with intermediate/high baseline 10-year ASCVD risk. Of these, eight of nine patients with malignancies had baseline MetS. In the PsO cohort, IR of malignancies was notably greater with high versus low/borderline/intermediate baseline 10-year ASCVD risk. Conclusion: In tofacitinib-treated patients with PsA/PsO, increased ASCVD risk and baseline MetS were associated with higher IRs for MACE and malignancies. Our results support assessing CV risk in patients with PsA/PsO and suggest enhanced cancer monitoring in those with increased ASCVD risk. Registration ClinicalTrialsgov: NCT01877668/NCT01882439/NCT01976364/NCT00678210/NCT01710046/NCT01241591/NCT01186744/NCT01276639/NCT01309737/NCT01163253. Plain Language Summary: People who have psoriatic arthritis or psoriasis may have more heart-related problems and cancer if they have a higher risk of cardiovascular disease: A study in people with psoriatic arthritis or psoriasis receiving tofacitinib Why was this study done? ⢠People with psoriatic arthritis (PsA) and psoriasis (PsO) are more likely than the general population to have a disease affecting the heart and blood vessels [cardiovascular (CV) disease].⢠People who are more likely to have CV disease may also be more likely to have certain types of cancer.⢠Tofacitinib is a medicine to treat people with PsA and has been tested in people with PsO.⢠We wanted to know if the risk of CV disease affects the number of heart-related problems (including heart attack, stroke, or death) and cancer in people with PsA and PsO. What did the researchers do? ⢠We used results from 10 clinical trials.⢠In these trials, people with PsA and PsO were taking tofacitinib 5 or 10 mg twice a day.⢠After the trials had ended, we measured people's risk of CV disease using a risk calculator. This risk calculator showed if they had a low, borderline, intermediate, or high risk of CV disease over the next 10 years. We also checked if they had had CV disease before treatment.⢠We checked if people had a group of conditions linked to CV disease: diabetes, high blood pressure, and obesity.⢠We counted the cases of heart-related problems and cancer in people once they started taking tofacitinib. What did the researchers find? In people with PsA and PsO taking tofacitinib:⢠There were more cases of heart-related problems and cancer in people who had intermediate or high risk of CV disease.⢠There were more cases of heart-related problems in people who had had CV disease before.⢠More people with diabetes, high blood pressure, and obesity had heart-related problems and cancer than people without those conditions. What do the findings mean? ⢠It is important to measure risk and assess history of CV disease in people with PsA and PsO, including those taking tofacitinib.⢠We should test for cancer in people with high risk of CV disease.
RESUMO
OBJECTIVE: To study levels of sick leave and disability pension before and after TNF-antagonist therapy in AS patients. METHODS: Using the population-based South Swedish Arthritis Treatment Group register, we identified 139 AS patients (aged 18-58 years, 78% men), who between January 2002 and December 2008 started their first treatment with adalimumab, etanercept or infliximab. We linked data to the payment register by the Swedish Social Insurance Agency and calculated the proportion on sick leave in 30-day intervals from 12 months before treatment start until 12 months after. For each AS patient, we randomly selected four subjects from the general population matched for age, sex and area of residence. RESULTS: One to 3 months before treatment, an average of 24% of AS patients were on sick leave. During the first 6 months after treatment start, this fraction dropped to 15%, and further declined to 12% at 12 months (P < 0.001). Comparing AS patients with the general population, the relative risk of being on sick leave 3 months before treatment, treatment start and 12 months after treatment start was 8.0 (95% CI 4.6, 13.9), 9.2 (95% CI 5.4, 15.7) and 4.0 (95% CI 2.1, 6.3), respectively. The decrease in sick leave was not substantially offset by changes in disability pension. CONCLUSION: There is a decline in sick leave during the first 12 months after initiation of TNF-antagonist treatment in AS patients not explained by societal factors or secular trends. The proportion of AS patients on disability pension remained unchanged during the observation period.

BACKGROUND: Patients with chronic inflammatory diseases (CIDs) may encounter challenges in their family planning journey. Here, we report on the access to family planning and pregnancy (FPP) information and the concerns among patients in Denmark with CIDs. METHODS: Patients aged 18-50 years with CIDs participated in an online survey. Patients were recruited through patient advocacy groups and were asked to report information on their diagnosis, concerns related to FPP and perceptions of access to FPP information. Descriptive statistics were applied. RESULTS: Of the eligible respondents, 368 had rheumatological diagnoses (rheumatoid arthritis, psoriatic arthritis, juvenile idiopathic arthritis or axial spondyloarthritis; mean age 40 years; 83% women, 17% men) and 95 had dermatological diagnoses (psoriasis or psoriatic arthritis; mean age 38 years; 67% women, 33% men). Approximately 70% of all patients reported seeking FPP information from patient advocacy groups; 57% of both cohorts used the internet as information sources; and 73% and 42% of rheumatological and dermatological cohorts used their hospital and specialist doctor, respectively. Despite this, 58% and 67% of patients with rheumatological and dermatological diagnoses reported limited or no access to FPP information, with > 70% of dermatological patients of early/mid-reproductive age reporting a lack of access to this information. Overall, 68% of patients with rheumatological and 73% with dermatological diagnoses had biological children, amongst whom 24% and 18%, respectively, indicated their disease affected the number of children they ultimately decided to have. The most frequent FPP concerns among patients who did not want any/more biological children were disease worsening, heredity and taking care of the child. CONCLUSIONS: Despite awareness of available sources of FPP information, patients expressed experiencing a feeling of limited access to information and having concerns that affect key decisions regarding FPP. The results of this survey highlight a need for improved and more standardised FPP information for patients with CIDs in Denmark.
RESUMO
OBJECTIVE: To investigate the risk of medical complications following total hip and knee arthroplasty (THA/TKA) among rheumatoid arthritis (RA) compared with osteoarthritis (OA) patients; and, to assess the risk of complications among biologics-treated RA patients. METHODS: In a nationwide register-based study, patients with RA and OA with THA/TKA surgery between 2000 and 2015 were identified and followed up to 90 days after surgery for venous thromboembolism (VTE), myocardial infarction and stroke, and non-surgical infections, respectively. Information on treatment with biologics was obtained in the DANBIO rheumatology register to compare risks of complications with non-biologics treated. RESULTS: A total of 2899 and 112,571 patients with RA and OA had THA/TKA. RA was associated with a hazard ratio (HR) of 1.29 (1.03 to 1.61) for infection following THA/TKA, but a HR of 0.60 (0.26 to 0.98) for VTE following TKA. Biologics treated patients had a HR of 1.35 (0.65 to 2.80) for infection and 4.82 (1.67 to 13.90) for VTE compared with non-biologics treated RA patients. RA patients had no increased risk of post-surgical myocardial infarction and stroke (HR 1.16, 0.76 to 1.78) compared with OA, but a higher incidence proportion was observed in biologics treated compared with non-biologics treated (1.0% vs 0.6%); however, the number of events were too small to estimate a HR. CONCLUSION: In this study, RA was a risk factor for infection after THA/TKA, and RA patients treated with biologics had a slightly increased risk compared with non-biologics treated RA patients. Compared with OA, RA patients had a lower risk of VTE following THA/TKA, but our finding of increased incidences of VTE in biologics-treated patients warrants further studies.

Background: Anti-tumor necrosis factor (anti-TNF) adherence is suboptimal. ava®, a reusable electromechanical self-injection device (e-Device) developed for certolizumab pegol (CZP) administration, aims to overcome some barriers to increase adherence. This study evaluates patient experience of the e-Device and its training materials and determines patient device preference.Methods: CZP-treated patients were recruited from the Netherlands, Denmark and Sweden. Patients completed a pre-injection Assessment of Self-Injection (ASI) questionnaire investigating self-injection perception. After training, patients administered 3 consecutive self-injections using the e-Device, patient experience of each was assessed using the post-injection ASI. An additional questionnaire evaluated training materials. After Injection 3, patients indicated their preference: the e-Device or their previous device.Results: 59 patients participated; most rated the e-Device highly for satisfaction, self-confidence and ease of use. The (negative) feelings and pain and skin reactions domains had low ratings. Post-injection ASI domain scores were similar following each of the 3 e-Device injections. Training materials were rated highly (video: 8.4/10; step-by-step guide: 8.4/10). 57.1% (32/56) patients preferred the e-Device over their previous self-injection device.Conclusions: Patients were satisfied with the e-Device and most preferred it over other self-injection devices. By improving patient experience, the e-Device may help increase medication adherence.

The Assessment of SpondyloArthritis international Society (ASAS) has defined core sets for (i) symptom-modifying anti-rheumatic drugs (SM-ARD), (ii) clinical record keeping, and (iii) disease-controlling anti-rheumatic therapy (DC-ART). These include the following domains for all three core sets: "physical function," "pain," "spinal mobility," "spinal stiffness," and "patient's global assessment" (PGA). The core set for clinical record keeping further includes the domains "peripheral joints/entheses" and "acute phase reactants," and the core set for DC-ART further includes the domains "fatigue" and "spine radiographs/hip radiographs." The Outcome Measures in Rheumatology (OMERACT) endorsed the core sets in 1998.Using empirical evidence from axSpA trials, we investigated the efficacy (i.e., net benefit) according to the ASAS/OMERACT core outcome set for axSpA across all interventions tested in trials included in subsequent Cochrane reviews. For all continuous scales, we combined data using the standardized mean difference (SMD) to meta-analyze outcomes involving the same domains. Also, through meta-regression analysis, we examined the effect of the separate SMD measures (independent variables) on the primary endpoint (log [OR], dependent variable) across all trials.Based on 11 eligible Cochrane reviews, from these, 85 articles were screened; we included 43 trials with 63 randomized comparisons. Mean (SD) number of ASAS/OMERACT core outcome domains measured for SM-ARD/physical therapy trials was 4.2 (1.7). Six trials assessed all proposed domains. Mean (SD) for number of core outcome domains for DC-ART trials was 5.8 (1.7). No trials assessed all nine domains. Eight trials (16%) were judged to have inadequate (i.e., high risk of) selective outcome reporting bias. The most responsible core domains for achieving success in meeting the primary objective per trial were pain, OR (95% CI) 5.19 (2.28, 11.77), and PGA, OR (95% CI) 1.87 (1.14, 3.07). In conclusion, selective outcome reporting (and "missing data") should be reduced by encouraging the use of the endorsed ASAS/OMERACT outcome domains in clinical trials. Overall outcome reporting was good for SM-ARD/physical therapy trials and poor for DC-ART trials. Our findings suggest that both PGA and pain provide a valuable holistic construct for the assessment of improvement beyond more objective measures of spinal inflammation.

Biologic drugs (e.g. anti-tumor necrosis factors) are effective treatments for multiple chronic inflammatory diseases including rheumatoid arthritis, axial spondyloarthritis, and psoriatic arthritis. Administration of biologic drugs is usually via subcutaneous self-injection, which provides many patient benefits compared to infusions including increased flexibility, reduced costs, and reduced caregiver burden. However, it is also associated with challenges such as needle phobia, patient treatment misconceptions and incorrect drug administration, and can be impacted by dexterity problems. Evidence suggests these problems, along with other drug administration challenges (e.g. patient forgetfulness, busy lifestyles, and polypharmacy), can reduce patient adherence to treatment. To combat these challenges, patient feedback has been used to develop a range of self-injection devices, including pre-filled syringes, pre-filled pens, and electronic injection devices. Providing different devices for drug administration gives patients the opportunity to choose a device that addresses the challenges they face as an individual. Research suggests involving patients in medical device development, providing patients with a choice of devices and enrolling individuals in patient support programs can empower patients to take control of their treatment journey. By providing a portfolio of self-injection devices, designed based on patient needs, patient experience will improve, potentially improving adherence and hence, long-term treatment outcomes.

BACKGROUND: The aim of this study was to explore the impact of sex and disease classification on outcomes in axial spondyloarthritis (axSpA) patients, including both radiographic (r-) axSpA and non-radiographic (nr-) axSpA, in males and females, respectively. METHODS: AxSpA patients were consecutively recruited from two rheumatology outpatient university clinics. We explored how sex and axSpA disease classification affected patient-reported outcome measures (PROMs). General linear models were used to investigate if there was an association between the continuous variables and each of the main effects of interest (sex and axSpA classification), as well as the possible interaction between them. Categorical outcome measures were analyzed with the use of logistic regression with the same fixed effects. We analyzed the relationship between tender point count (TPC) and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). The prevalence of extra-articular manifestations (EAMs) and the Charlson Comorbidity Index (CCI) were determined. RESULTS: According to the protocol, a total of 100 outpatients with axSpA were enrolled (r-axSpA males 30, r-axSpA females 10, nr-axSpA males 25, nr-axSpA females 35). The BASDAI scores appeared higher among nr-axSpA females (median [Q1; Q3], 47 [21; 60]) compared with the combined median for the 3 other subgroups 25 [12; 25]. Female sex was associated with a higher number of tender point count (TPC, P < 0.001). TPC and BASDAI were correlated for female nr-axSpA patients (r = 0.44, P = 0.008) and male nr-axSpA patients (r = 0.56, P = 0.003). Being classified as nr-axSpA was associated with a lower SF-36 Mental Component Summary (median for the 4 subgroups: nr-axSpa females 46.7, nr-axSpA males 52.3 vs. r-axSpA males 56.9 and r-axSpA females 50.4). EAMs were frequent (up to 50%). The CCI was low in all 4 subgroups, and no difference in the CCI between the subgroups was observed (P = 0.14). However, male sex had a significant impact on the CCI (P = 0.03). CONCLUSIONS: In summary, patients with r-axSpA, regardless of sex, appeared less affected on most PROMs compared with nr-axSpA patients. However, female sex was associated with a higher number of TPC. TPC could possibly confound disease activity outcomes such as BASDAI, and one can consider different thresholds for defining high disease activity depending on the patient's sex. TRIAL REGISTRATION: The trial is registered and approved by the Region of Southern Denmark's Ethics Committee ( S-20150219 ). Registered 19 February 2015.

OBJECTIVES: To assess the efficacy and safety of methotrexate (MTX) in combination with an approved biological agent compared to biological monotherapy, in the management of patients with rheumatoid arthritis (RA). METHODS: MEDLINE, EMBASE, CENTRAL and other sources were searched for randomised trials evaluating a biological agent plus MTX versus the same biological agent in monotherapy. Co-primary outcomes were ACR50 and the number of patients who discontinued due to adverse events (AEs). Random-effects models were applied for meta-analyses with risk ratio and 95% confidence intervals and the GRADE approach was used to assess confidence in the estimates. RESULTS: The analysis comprised 16 trials (4965 patients), including all biological agents approved for RA except anakinra and certolizumab. The overall likelihood of responding to therapy (i.e. ACR50) after 6 months was 32% better when MTX was given concomitantly with biological agents (1.32 [1.20-1.45]; P < 0.001) corresponding to 11 more out of 100 patients (7-16 more); Moderate Quality Evidence. Discontinuing due to AEs from concomitant use of MTX was potentially 20% increased (1.21 [0.97-1.50]; Pâ¯=â¯0.09) compared to biological monotherapy corresponding to 1 more out of 100 patients (0-3 more); Moderate Quality Evidence. CONCLUSIONS: Randomised trials provide Moderate Quality Evidence for a favourable benefit-harm balance supporting concomitant use of MTX rather than monotherapy when prescribing a biological agent in patients with RA although in absolute terms only 7-16 more out of 100 patients will achieve an ACR50 response after 6 months of this combination therapy.

OBJECTIVE: To assess the importance of trial characteristics as contextual factors when evaluating the treatment effect of targeted therapies for patients with psoriatic disease. METHODS: We identified randomized controlled trials (RCTs) evaluating targeted therapies approved for psoriatic arthritis (PsA) and psoriasis (8 biologics and apremilast). The effect of targeted therapies was analyzed in the 2 psoriatic conditions combined by using drug retention as a common outcome, and separately by using the American College of Rheumatology 20% improvement criteria (ACR20) for PsA and the Psoriasis Area Severity Index 75% improvement score (PASI75) for psoriasis. We explored potential effect modification of trial characteristics in stratified and meta-regression analyses. Odds ratios (ORs) were calculated and compared among the trial eligibility criteria via the ratio of ORs. RESULTS: Forty-eight PsA and psoriasis trials (51 comparisons; 17,737 patients) were eligible. Overall retention was OR 2.16 (95% confidence interval [95% CI] 1.70-2.75) with higher odds for PsA trials compared with psoriasis trials (ratio of ORs 2.55 [95% CI 1.64-3.97]). The eligibility criteria "targeted therapy history," "minimum required disease duration," "required negative rheumatoid factor," and "required Classification Criteria for Psoriatic Arthritis criteria" were of importance for achieving ACR20 in PsA. The eligibility criterion "minimum required disease duration" was of importance for achieving PASI75 in psoriasis. A total of 7 PsA trials had rescue before time-point-of-retention reporting (adaptive trials). CONCLUSION: From this exploratory meta-epidemiologic study, we now have evidence from RCTs to support the notion that patients with PsA are more likely to adhere to targeted therapies compared to patients with psoriasis. Furthermore, we identified a few contextual factors of importance in regard to achieving ACR20 in PsA trials and PASI75 in psoriasis trials.

BACKGROUND: An updated psoriatic arthritis (PsA) core outcome set (COS) for randomized controlled trials (RCTs) was endorsed at the Outcome Measures in Rheumatology (OMERACT) meeting in 2016. OBJECTIVES: To synthesize the evidence on measurement properties of patient reported outcome measures (PROMs) for PsA and thereby contribute to development of a PsA core outcome measurement set (COMS) as described by the OMERACT Filter 2.0. METHODS: A systematic literature search was performed in EMBASE, MEDLINE and PsycINFO on Jan 1, 2017 to identify full-text articles with an aim of assessing the measurement properties of PROMs in PsA. Two independent reviewers rated the quality of studies using the COnsensus based standards for the Selection of health Measurement INstruments (COSMIN) checklist, and performed a qualitative evidence synthesis. RESULTS: Fifty-five studies were included in the systematic review. Forty-four instruments and a total of 89 scales were analyzed. PROMs measuring COS domains with at least fair quality evidence for good validity and reliability (and no evidence for poor properties) included the Stockerau Activity Score for PsA (German), Psoriasis Symptom Inventory, visual analogue scale for Patient Global, 36 Item Short Form Health Survey Physical Function subscale, Health Assessment Questionnaire Disability Index, Bath Ankylosing Spondylitis Functional Index, PsA Impact of Disease questionnaire, PsA Quality of Life questionnaire, VITACORA-19, Functional Assessment of Chronic Illness Therapy Fatigue scale and Social Role Participation Questionnaire. CONCLUSIONS: At least one PROM with some evidence for aspects of validity and reliability was available for six of the eight mandatory domains of the PsA COS.

OBJECTIVE: Outcomes important to patients are those that are relevant to their well-being, including quality of life, morbid endpoints, and death. These outcomes often occur over the longterm and can be identified in prospective longitudinal observational studies (PLOS). There are no standards for which outcome domains should be considered. Our overarching goal is to identify critical longterm outcome domains for patients with rheumatic diseases, and to develop a conceptual framework to measure and classify them within the scope of OMERACT Filter 2.0. METHODS: The steps of this initiative primarily concern rheumatoid arthritis (RA) and include (1) performing a systematic review of RA patient registries and cohorts to identify previously collected and reported outcome domains and measurement instruments; (2) developing a conceptual framework and taxonomy for identification and classification of outcome domains; (3) conducting focus groups to identify domains considered critical by patients with RA; and (4) surveying patients, providers, and researchers to identify critical outcomes that can be evaluated through the OMERACT filter. RESULTS: In our initial evaluation of databases and registries across countries, we found both commonalities and differences, with no clear standardization. At the initial group meeting, participants agreed that additional work is needed to identify which critical outcomes should be collected in PLOS, and suggested several: death, independence, and participation, among others. An operational strategy for the next 2 years was proposed. CONCLUSION: Participants endorsed the need for an initiative to identify and evaluate critical outcome domains and measurement instruments for data collection in PLOS.

OBJECTIVES: To summarize and compare the benefits and harms of biological agents used as monotherapy for rheumatoid arthritis (RA) in order to inform decisions for patients who are intolerant to conventional DMARD therapy. METHODS: We searched MEDLINE, EMBASE, CENTRAL, and other sources for randomised trials that compared biological monotherapy with methotrexate, placebo, or other biological monotherapies. Primary outcomes were ACR50 and the number of patients who discontinued due to adverse events. Our network meta-analysis was based on mixed-effects logistic regression, including both direct and indirect comparisons of the treatment effects, while preserving the randomised comparisons within each trial. PROSPERO identifier: CRD42012002800. RESULTS: The analysis comprises 28 trials (8602 patients), including all nine biological agents approved for RA. Eight trials included "DMARD-naïve", and 20 "DMARD-Inadequate responder" (DMARD-IR) patients. All agents except anakinra and infliximab were superior (p < 0.05) to placebo (i.e., no DMARD treatment) with regard to ACR50. Etanercept and rituximab were superior to anakinra (p = 0.018 and p = 0.049, respectively). Tocilizumab was superior to adalimumab (p = 0.0082), anakinra (p = 0.0083), certolizumab (p = 0.037), and golimumab (p = 0.049). No differences among etanercept, tocilizumab, and rituximab were found (p > 0.52). However, because rituximab was evaluated in just 40 patients, our confidence in the estimates is limited. When including only DMARD-IR trials, the same statistical pattern emerged; in addition etanercept and tocilizumab were superior to abatacept. At recommended doses, both etanercept and tocilizumab were superior to adalimumab and certolizumab. No statistically significant differences among biological agents were found with respect to discontinuation due to adverse events (p > 0.068). CONCLUSIONS: Evidence from randomised trials suggests that most biological agents are effective as monotherapy. Although our confidence in the estimates is limited, etanercept or tocilizumab may be the optimal choice for most patients who need treatment with biological monotherapy. However, given our limited confidence in the estimates including possibility of bias, it is appropriate to strongly weight patients׳ preferences and values in the final treatment choice.
