Objective To identify a core set of domains (outcomes) to be measured in psoriatic arthritis (PsA) clinical trials that represent both patients' and physicians' priorities. Methods We conducted (1) a systematic literature review (SLR) of domains assessed in PsA; (2) international focus groups to identify domains important to people with PsA; (3) two international surveys with patients and physicians to prioritise domains; (4) an international face-to-face meeting with patients and physicians using the nominal group technique method to agree on the most important domains; and (5) presentation and votes at the Outcome Measures in Rheumatology (OMERACT) conference in May 2016. All phases were performed in collaboration with patient research partners. Results We identified 39 unique domains through the SLR (24 domains) and international focus groups (34 domains). 50 patients and 75 physicians rated domain importance. During the March 2016 consensus meeting, 12 patients and 12 physicians agreed on 10 candidate domains. Then, 49 patients and 71 physicians rated these domains' importance. Five were important to >70% of both groups: musculoskeletal disease activity, skin disease activity, structural damage, pain and physical function. Fatigue and participation were important to >70% of patients. Patient global and systemic inflammation were important to >70% of physicians. The updated PsA core domain set endorsed by 90% of OMERACT 2016 participants includes musculoskeletal disease activity, skin disease activity, pain, patient global, physical function, health-related quality of life, fatigue and systemic inflammation. Conclusions The updated PsA core domain set incorporates patients' and physicians' priorities and evolving PsA research. Next steps include identifying outcome measures that adequately assess these domains.

Objective. To examine the distribution of traditional and novel risk factors of cardiovascular disease (CVD) in patients with PsA compared with healthy controls. Methods. We compared risk factors for CVD between 102 consecutive PsA patients and 82 controls, adjusting for BMI. We also assessed the role of inflammation on the CVD risk factor by using a BMI and high-sensitivity CRP (hsCRP)-adjusted model. Results. The BMI of PsA patients were significantly higher than healthy controls. After adjusting for the BMI, PsA patients still have a higher prevalence of diabetes mellitus (DM) [odds ratio (OR) 9.27, 95% CI 2.09, 41.09) and hypertension (OR 3.37, 95% CI 1.68, 6.72), but a lower prevalence of low high density lipoprotein (HDL) cholesterol (OR 0.16, 95% CI 0.07, 0.41). PsA patients have significantly increased systolic and diastolic blood pressures, insulin resistance and inflammatory markers (hsCRP and white cell count) compared to controls. PsA patients have higher HDL cholesterol and apolipoprotein (Apo) A1 levels; and lower total cholesterol (TC) and low density lipoprotein cholesterol levels; and a lower TC/HDL ratio. However, the Apo B level (P < 0.05), and the Apo B/Apo A1 ratio (P = 0.07) were higher in PsA patients. Further adjustment for hsCRP level rendered the differences in the prevalence of hypertension and DM; the TC, and sugar levels; and white cell count non-significant between the two groups; while the differences in other parameters remained significant. Conclusion. These data support the hypothesis that PsA may be associated with obesity, hypertension, dyslipidaemia and insulin resistance because of the shared inflammatory pathway.

Disease activity 6 months before pregnancy of patients with systemic lupus erythematosus (SLE) associated with adverse maternal and fetal outcomes is not well studied. The aim of the study was to identify predictors of adverse maternal and fetal outcomes in pregnant SLE patients, based on patients’ background characteristics, clinical and laboratory data 6 months before pregnancy. Of 103 pregnancies, 55 pregnancies in 39 SLE patients were investigated. Clinical and laboratory data were recorded at regular intervals from 6 months before conception to 1 year after delivery. Primary outcomes included the predictors of combined adverse maternal and fetal outcomes. Potential explanatory variables included demographic, clinical and laboratory data 6 months before conception. Using logistic regression, history of nephritis (p = 0.001, odds ratio [OR] 13.3, 95% confidence interval [CI] 2.7–65.1) and a high SLE Disease Activity Index (SLEDAI) score 6 months before pregnancy (p = 0.015, OR 1.7, 95% CI 1.1–2.7) were associated with combined adverse maternal outcome, whereas flare during pregnancy (p = 0.003, OR 29.3, 95% CI 3.1–273.1) predicted combined adverse fetal outcome. The area under the curve for SLEDAI score of combined maternal outcome was 0.73 (95% CI 0.58–0.87). The optimal cut-off point according to the receiver operating characteristic curve was 4, with a sensitivity of 64% and a specificity of 75%. In conclusion, a history of nephritis or a SLEDAI score of 4 or more in SLE patients 6 months before conception predicts adverse maternal outcomes, while disease flare during pregnancy predicts adverse fetal outcomes. Pregnancies should be delayed until the disease has been in remission for 6 months.

Objective: To examine the prevalence of subclinical atherosclerosis in patients with psoriatic arthritis (PsA) compared with healthy controls, and to identify clinical and biologic markers for atherosclerotic disease in this patient population.Methods: Subclinical atherosclerosis was defined as the average of intima‐media thickness (IMT) measures in the common carotid artery, bifurcation, and internal carotid artery on both sides above the 95th percentile of healthy controls. IMT was measured using carotid ultrasonography in 82 consecutive PsA patients and 82 healthy controls matched on age, sex, and ethnicity. We also ascertained traditional and novel cardiovascular (CV) risk factors, Framingham risk score (FRS), disease severity, treatment, and inflammatory markers in all PsA patients.Results: No PsA patients had clinically overt CV diseases. After adjusting for traditional CV risk factors, PsA patients had a higher prevalence of subclinical atherosclerosis. PsA patients with subclinical atherosclerosis had significantly increased sugar, total triglyceride levels, total cholesterol/high‐density cholesterol, white cell count, and patients' global assessment score compared with those without subclinical atherosclerosis. Using logistic regression analysis, independent explanatory variables associated with subclinical atherosclerosis in PsA included increased sugar and total triglyceride levels. The FRS was similar in PsA patients with or without subclinical atherosclerosis. Twenty‐six (35%) of 74 patients had subclinical atherosclerosis despite having a low CV risk.Conclusion: PsA is associated with subclinical atherosclerosis after adjusting for traditional CV risk factors. Independent explanatory variables associated with subclinical atherosclerosis in PsA included increased sugar and total triglyceride levels. Carotid IMT can identify PsA patients with subclinical atherosclerosis who may benefit from early intervention.
