Objective
Long-term gout management is based on reducing serum urate by using urate-lowering therapy (ULT). A lifelong treat-to-target approach is advocated, although a ULT (taper to) stop attempt can be considered (treat-to-avoid symptoms approach) during remission. Exploring the beliefs of patients with gout on long-term ULT strategies during remission is important for optimizing gout management. We aimed to identify factors that influence the decision for continuation or discontinuation of ULT and to determine their relative importance according to patients with gout in remission.
Methods
A mixed-methods design was used. First, semistructured interviews (substudy 1) were conducted to identify barriers and facilitators for the (dis)continuation of ULT using inductive thematic analysis. Afterwards, these barriers/facilitators were summarized into neutrally phrased items and used in a maximum difference scaling study (substudy 2) to determine their relative importance using the rescaled probability score.
Results
Substudies 1 and 2 included 18 and 156 patients, respectively. Substudy 1 yielded 22 items within 10 overarching themes. Substudy 2 revealed that the perceived risk of joint damage and gout flares and that ULT use gives some assurance were the most important items. The costs, ease of receiving ULT, and its practical use were the least important items.
Conclusion
These results can aid shared decision-making and provide input for what is important to discuss with patients with gout in remission when they consider ULT discontinuation. The emphasis should be on the risk of having gout flares and joint damage, not so much on facilitating how easily medication is received.

Objective
Limited data exist on the natural history of shoulder symptoms. We aimed to describe longitudinal patterns of shoulder symptoms and determine risk factors for incidence and persistence.
Methods
Data from Osteoarthritis Initiative participants observed annually for four years were used to describe shoulder symptom (yes/no, side) incidence and prevalence using descriptive analyses. Regression analyses investigated the association among three shoulder symptoms outcomes (persistent, incident, and intermittent) and clinical factors. Latent class growth analysis (LCGA) identified trajectories in those reporting pain at one or more time point.
Results
In total, 4,796 participants (58% women, mean age 61.2 years) were included. Baseline shoulder symptom prevalence was 22%; 32% of these reported bilateral symptoms. In those reporting right symptoms, 260 of 1,886 (14%) had persistent symptoms. Those with persistent symptoms had worse baseline and four-year clinical status (poorer function, mental health, and quality of life). In regression analysis, persistent symptoms were associated with sleep disturbance (adjusted odds ratio [aOR] 1.97, 95% confidence interval [95% CI] 1.49–2.62), work absenteeism (aOR 2.16, 95% CI 1.38–2.62), lower limb weakness (aOR 1.76, 95% CI 1.37–2.27), multiple-site joint symptoms (≥3 joints excluding shoulders) (aOR 4.90, 95% CI 2.79–8.58) and White race (aOR 1.39, 95% CI 1.04–1.88). Lower limb weakness was also associated with incident symptoms; no variables were associated with intermittent symptoms. LCGA identified two trajectories: the trajectory with high probability for symptoms (9% of LCGA analysis cohort) showed similar relationships to clinical variables as in the persistent symptoms group.
Conclusion
In this large, four-year study, persistent shoulder symptoms were common and associated with worse clinical outcomes. At least one risk factor for incident symptoms is modifiable.

Objective
The objective of this study was to evaluate the impact of protocol violations in the treat-to-target group in the Tight Control in Spondyloarthritis (TICOSPA) trial and to compare the proportion of patients optimally treated according to the Assessment of Spondyloarthritis International Society (ASAS)/EULAR 2016 recommendations for patients with axial spondyloarthritis (axSpA) between the treat-to-target versus usual care (UC) arms.
Methods
This study was a cluster-randomized, controlled 48-week trial including patients with axSpA who fulfilled the ASAS criteria, had an Axial Spondyloarthritis Disease Activity Score >2.1, and were biologic disease-modifying antirheumatic drug naive. Eighteen axSpA expert centers were randomly allocated to one treatment arm: (a) treat-to-target prespecified management strategy (four-week visits), and (b) UC treatment decisions at the rheumatologist's discretion (12-week visits). Protocol violations in the treat-to-target arm and the fulfillment of the 2016 ASAS/EULAR recommendations in both arms were evaluated at every visit. ASAS Health Index (ASAS-HI) and disease activity outcomes at 48 weeks were compared between treat-to-target violators versus nonviolators. Patients treated according to the ASAS/EULAR recommendations were compared between both arms.
Results
A total of 160 patients initiated the trial (80 patients with treat to target; 80 patients with UC). In the treat-to-target arm, 51.2% patients violated the protocol at least once (62.2% of violations resulting in maintenance/reduction of treatment against protocol). After 48 weeks, treat-to-target violators versus nonviolators showed similar ratios of ASAS-HI improvement. The proportion of patients managed according to the ASAS/EULAR recommendations after the first 12 weeks were 63.9% versus 61.8% for the treat-to-target and UC arms, respectively.
Conclusion
Protocol violations in the treat-to-target arm in the TICOSPA trial were frequent, although they did not have an impact on the rate of the primary outcome. The groups with UC was optimally treated, partly explaining the nonachievement of the primary objective in the TICOSPA trial.

Objective
We sought to evaluate urate-lowering therapy (ULT) adherence and treatment-to-target (T2T) serum uric acid (SUA) levels among older adults with gout starting ULT.
Methods
We performed a population-based retrospective cohort study in Ontario, Canada in patients with gout aged ≥66 years newly dispensed ULT between 2010 and 2019. We defined successful T2T as patients having SUA levels <360 μmol/L (6 mg/dL) within 12 months after ULT dispensation. We also assessed adherence to ULT. Multilevel logistic regression clustered by ULT prescriber evaluated patient, physician, and prescription factors associated with reaching target SUA levels.
Results
Among 44,438 patients (mean ± SD age 76.0 ± 7.3 years; 64.4% male), 30,057 (67.6%) patients had ≥1 SUA test completed. Overall, 52.3% patients reached SUA target within 12 months, improving from 45.2% in 2010 to 61.2% in 2019 (P < 0.0001). ULT adherence was 55.3% overall and improved annually. Key factors associated with achieving T2T included febuxostat treatment (odds ratio [OR] 11.40, 95% confidence interval [95% CI] 5.10–25.43) (was only dispensed in 88 patients), ULT adherence (OR 5.17, 95% CI 4.89–5.47), allopurinol starting doses >50 mg (OR 2.53, 95% CI 2.14–2.99), colchicine/oral glucocorticoids co-prescription (OR 1.24, 95% CI 1.14–1.34), and ULT prescription from a rheumatologist.
Conclusion
Only 52.3% of patients achieved an optimal SUA level within 1 year of ULT initiation. ULT adherence was suboptimal, although improving over time. ULT adherence and higher allopurinol starting doses had the strongest associations of achieving a target SUA level. This study highlights room for improvement in gout management and potential strategies to address care gaps.
目标：我们试图评估开始使用 ULT 的老年痛风患者的降尿酸治疗（ULT）依从性和治疗目标（T2T）血清尿酸（SUA）水平：我们在加拿大安大略省开展了一项基于人群的回顾性队列研究，研究对象是 2010 年至 2019 年间新配发 ULT 的年龄≥66 岁的痛风患者。我们将成功进行 T2T 的患者定义为达到 SUA 水平的患者：在 44,438 名患者（平均（标清）年龄为 76.0±7.3 岁；64.4% 为男性）中，30,057 名患者（67.6%）完成了≥1 次 SUA 测试。总体而言，52.3%的患者在12个月内达到了SUA目标，从2010年的45.2%提高到2019年的61.2%（p < 0.0001）。超短波治疗依从性总体为 55.3%，并逐年提高。与实现 T2T 相关的关键因素包括非布司他的使用（OR 11.40，95% CI 5.10-25.43）（仅有 88 名患者获得配药）、超短波治疗的依从性（OR 5.17，95% CI 4.89-5.47）、开始使用别嘌醇（OR 5.17，95% CI 4.89-5.47）。47）、别嘌呤醇起始剂量大于 50 毫克（OR 2.53，95% CI：2.14-2.99）、秋水仙碱/口服皮质类固醇联合处方（OR 1.24，95% CI：1.14-1.34）以及风湿免疫科医生开具的 ULT 处方：结论：只有 52.3% 的患者在开始使用超短波治疗一年内达到了最佳 SUA 水平。超短波治疗的依从性不理想，但随着时间的推移有所改善。坚持超短波治疗和较高的别嘌呤醇起始剂量与达到目标 SUA 水平的关系最为密切。这项研究强调了痛风治疗中有待改进的地方，以及解决治疗差距的潜在策略。

Objective
Having a low complement level is associated with clinical systemic lupus erythematosus (SLE) disease activity and future organ damage. We studied the association of hydroxychloroquine (HCQ) whole blood levels with changes in complement level.
Methods
We performed two analyses on data prospectively collected from an SLE cohort. In the first (a “new starts on HCQ” analysis), we compared changes in complement level between those starting HCQ and those not starting it. The second analysis evaluated the association between HCQ whole blood levels and low complement level in all cohort visits using conditional logistic regression.
Results
In the “new starts on HCQ” analysis, a higher percentage of patients starting HCQ (as reflected in HCQ blood levels >50) experienced a normalization of C4 level compared to those not starting HCQ (23 of 57 [40%] vs. 9 of 56 [13%]; P = 0.011), as well as a significantly greater increase in both C3 and C4 level (P = 0.048 and P = 0.017, respectively). In the “all cohort visits” analysis, there was a statistically significant higher probability of having normal C4 levels in visits with higher HCQ whole blood levels (odds ratio 1.8–2.6 depending on the levels). This relationship was most pronounced for whole blood HCQ levels of 200 ng/mL or more.
Conclusion
We observed significant improvement in complement levels when HCQ was started and among those with higher whole blood levels of HCQ, particularly with respect to C4. Modulating the pathogenic mechanisms that lead to complement consumption may be one mode by which HCQ prevents poor outcomes in SLE.

Objective
Our objectives were to quantify the relationships among fatigue, pain interference, and physical disability in children with juvenile idiopathic arthritis (JIA) and to test whether fatigue mediates the relationship between pain interference and physical disability in JIA.
Methods
Patients enrolled within three months of JIA diagnosis in the Canadian Alliance of Pediatric Rheumatology Investigators (CAPRI) Registry between February 2017 and May 2023 were included. Their parents completed the Patient-Reported Outcomes Measurement Information System fatigue and pain interference short proxy questionnaires and the Childhood Health Assessment Questionnaire disability index at registry enrollment. Associations were assessed using Pearson correlations and multiple linear regression. Structural equation modeling (SEM) was used to test if fatigue mediates the relationship between pain interference and physical disability.
Results
Among 855 patients (61.4% female, 44.1% with oligoarthritis), most reported fatigue and pain interference scores similar to those in the reference population, but 15.6% reported severe fatigue and 7.3% reported severe pain interference, with wide variation across JIA categories. Fatigue was strongly correlated with pain interference (r = 0.72, P < 0.001) and with physical disability (r = 0.60, P < 0.001). Pain interference (β = 0.027, P < 0.001) and fatigue (β = 0.013, P < 0.001) were both associated with physical disability after controlling for each other and potential confounders. SEM supported our hypothesis that fatigue partially mediates the relationship between pain interference and physical disability.
Conclusion
Our findings suggest both fatigue and pain interference are independently associated with physical disability in children newly diagnosed with JIA, and the effect of pain interference may be partly mediated by fatigue.

Objective
The study objective was to determine predictors of gout flare when commencing allopurinol using the “start-low go-slow” dose escalation strategy.
Methods
A post hoc analysis of a 12-month double-blind placebo-controlled noninferiority trial with participants randomized 1:1 to colchicine 0.5 mg daily or placebo for the first six months was undertaken. Multivariate logistic regression models were used to identify independent predictors of gout flares in the first and last six months of the trial.
Results
Multivariable analysis revealed a significant association between risk of a gout flare in the first six months and flare in the month before starting allopurinol (odds ratio [OR] 2.65, 95% confidence interval [CI] 1.36–5.17) and allopurinol 100 mg starting dose (OR 3.21, 95% CI 1.41–7.27). The predictors of any gout flares in the last six months of the trial, after stopping colchicine or placebo, were having received colchicine (OR 2.95, 95% CI 1.48–5.86), at least one flare in the month before stopping study drug (OR 5.39, 95% CI 2.21–13.15), and serum urate ≥0.36 mmol/L at month 6 (OR 2.85, 95% CI 1.14–7.12).
Conclusion
Anti-inflammatory prophylaxis when starting allopurinol using the “start-low go-slow” dose escalation strategy may be best targeted at those who have had a gout flare in the month before starting allopurinol and are commencing allopurinol 100 mg daily. For those with ongoing gout flares during the first six months of starting allopurinol who have not yet achieved serum urate target, a longer period of prophylaxis may be required.

Objectives
This study compared opioid prescribing among ambulatory visits with systemic autoimmune/inflammatory rheumatic diseases (SARDs) or without and assessed factors associated with opioid prescribing in SARDs.
Methods
This cross-sectional study used the National Ambulatory Medical Care Survey between 2006 and 2019. Adult (≥18 years) visits with a primary diagnosis of SARDs, including rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, or systemic lupus erythematosus were included in the study. Opioid prescribing was compared between those with vs without SARDs using multivariable logistic regression accounting for the complex survey design and adjusting for predisposing, enabling, and need factors within Andersen's Behavioral Model of Health Services Use. Another multivariable logistic regression examined the predictors associated with opioid prescribing in SARDs.
Results
Annually, an average of 5.20 million (95% confidence interval [CI] 3.58–6.82) visits were made for SARDs, whereas 780.14 million (95% CI 747.56–812.72) visits were made for non-SARDs. The SARDs group was more likely to be prescribed opioids (22.53%) than the non-SARDs group (9.83%) (adjusted odds ratio [aOR] 2.65; 95% CI 1.68–4.18). Among the SARDs visits, patient age from 50 to 64 (aOR 1.95; 95% CI 1.05–3.65 relative to ages 18–49) and prescribing of glucocorticoids (aOR 1.75; 95% CI 1.20–2.54) were associated with an increased odd of opioid prescribing, whereas private insurance relative to Medicare (aOR 0.50; 95% CI 0.31–0.82) was associated with a decreased odds of opioid prescribing.
Conclusion
Opioid prescribing in SARDs was higher compared to non-SARDs. Concerted efforts are needed to determine the appropriateness of opioid prescribing in SARDs.
