Psychosocial outcomes and health status of adults who have had juvenile rheumatoid arthritis: a controlled, population-based study

Extrapolation of Upadacitinib Efficacy in Juvenile Idiopathic Arthritis Leveraging Pharmacokinetics, Exposure-Response Models, and Real-World Patient Data

Juvenile idiopathic arthritis (JIA) is the most prevalent pediatric rheumatic disease. While disease-modifying antirheumatic drugs (DMARDs), especially biologics, have greatly transformed the management of JIA, there remain some unmet medical needs that require new treatment options. The objective of this work was to describe and apply a modeling and simulation approach to extrapolate upadacitinib efficacy from the adult diseases, rheumatoid arthritis (RA) and psoriatic arthritis (PsA), to their respective pediatric diseases, polyarticular course JIA (pcJIA), and juvenile PsA (JPsA). A population pharmacokinetic model characterized upadacitinib pharmacokinetics in pediatric patients using data from two phase I studies in pediatric patients with pcJIA (N = 51) or atopic dermatitis (N = 33). Efficacy simulations were conducted using previously developed exposure-response models in adults with RA and PsA. Real-world pcJIA and JPsA patient databases were leveraged to construct representative patient profiles for the targeted population. Following administration of the proposed weight-based dosing regimen, the model-predicted median upadacitinib plasma exposures in pediatric patients were within 20% of those in adult RA and PsA patients receiving the approved adult regimen. Simulations demonstrate that upadacitinib efficacy in pcJIA and JPsA is predicted to be non-inferior to that in adults with RA or PsA, respectively. The results of this work enabled recent approvals of upadacitinib for the treatment of polyarticular JIA and JPsA in the United States. Upadacitinib safety in pediatrics is being further evaluated in ongoing clinical trials.

A lifelong journey: Long-term perspectives on Juvenile Idiopathic Arthritis

Juvenile Idiopathic Arthritis (JIA) represents a diverse group of chronic inflammatory conditions that begin in childhood or adolescence and continue into adulthood, with varying severity and outcomes. This review discusses the complexities of transitioning JIA patients emphasizing that inadequate transition from pediatric to adult care leads to loss of follow-up, treatment discontinuation, and increased disease activity. Furthermore, challenges in disease classification hinder continuity of care across lifespan. It is also pointed out that predicting long-term outcomes in JIA remains complex due to heterogeneity and evolving phenotypes. Factors such as disease category, joint involvement, and treatment influence disease activity, functional disability, and quality of life. Despite advancements in treatment strategies, a substantial proportion of patients experience long-term disability and joint damage. Finally, it is underscored that optimising long-term outcomes in adults with JIA requires a multifaceted approach encompassing structured transition processes, personalised treatment strategies, and comprehensive management of comorbidities. Further research is needed to refine predictive models, enhance disease monitoring tools, and understand the complex interplay between disease activity, treatment response, and long-term outcomes.

Do Patterns of Early Disease Severity Predict Grade 12 Academic Achievement in Youths With Childhood-Onset Chronic Rheumatic Diseases?

OBJECTIVE

To test the association of early disease severity with grade 12 standards test performance in individuals with childhood-onset chronic rheumatic diseases (ChildCRDs), including juvenile arthritis and systemic autoimmune rheumatic diseases.

METHODS

We used linked provincial administrative data to identify patients with ChildCRDs born between 1979 and 1998 in Manitoba, Canada. Primary outcomes were Language and Arts Achievement Index (LAI) scores and Math Achievement Index (MAI) scores from grade 12 standards test results as well as enrollment data. The secondary outcome was enrollment in grade 12 by 17 years of age. Latent class trajectory analysis identified disease severity groups using physician visits following diagnosis. Multivariable linear regression tested the association of disease severity groups with LAI and MAI scores, and logistic regression tested the association of disease severity with age-appropriate enrollment, after adjusting for sociodemographic factors and psychiatric morbidities.

RESULTS

The study cohort included 541 patients, 70.1% of whom were female. A 3-class trajectory model provided the best fit; it classified 9.7% of patients as having severe disease, 54.5% as having moderate disease, and 35.8% as having mild disease. After covariate adjustment, severe disease was associated with poorer LAI and MAI scores but not with age-appropriate enrollment.

CONCLUSION

Among patients with ChildCRDs, those with severe disease performed more poorly on grade 12 standards tests, independent of sociodemographic and psychiatric risk factors. Clinicians should work with educators and policy makers to advocate for supports to improve educational outcomes of patients with ChildCRDs.

A review of the pleiotropic actions of the IFN-inducible CXC chemokine receptor 3 ligands in the synovial microenvironment

Chemokines are pivotal players in instigation and perpetuation of synovitis through leukocytes egress from the blood circulation into the inflamed articulation. Multitudinous literature addressing the involvement of the dual-function interferon (IFN)-inducible chemokines CXCL9, CXCL10 and CXCL11 in diseases characterized by chronic inflammatory arthritis emphasizes the need for detangling their etiopathological relevance. Through interaction with their mutual receptor CXC chemokine receptor 3 (CXCR3), the chemokines CXCL9, CXCL10 and CXCL11 exert their hallmark function of coordinating directional trafficking of CD4+ TH1 cells, CD8+ T cells, NK cells and NKT cells towards inflammatory niches. Among other (patho)physiological processes including infection, cancer, and angiostasis, IFN-inducible CXCR3 ligands have been implicated in autoinflammatory and autoimmune diseases. This review presents a comprehensive overview of the abundant presence of IFN-induced CXCR3 ligands in bodily fluids of patients with inflammatory arthritis, the outcomes of their selective depletion in rodent models, and the attempts at developing candidate drugs targeting the CXCR3 chemokine system. We further propose that the involvement of the CXCR3 binding chemokines in synovitis and joint remodeling encompasses more than solely the directional ingress of CXCR3-expressing leukocytes. The pleotropic actions of the IFN-inducible CXCR3 ligands in the synovial niche reiteratively illustrate the extensive complexity of the CXCR3 chemokine network, which is based on the intercommunion of IFN-inducible CXCR3 ligands with distinct CXCR3 isoforms, enzymes, cytokines, and infiltrated and resident cells present in the inflamed joints.

Diagnostic Delays and Psychosocial Outcomes of Childhood-Onset Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder that manifests in affected individuals with a variety of clinical features and involves multiple organs. Despite recent advances over the past decades, higher morbidity and mortality have been reported by studies in patients with childhood-onset systemic lupus erythematosus (cSLE) compared to patients with adult-onset. The interplay of several factors can cause diagnostic delays resulting in worse disease activity, multiple organ damage, increased risk of hospitalization, and management with aggressive treatment. Significant factors include demographic, clinical, and socioeconomic characteristics of patients with cSLE. Moreover, despite recent advances in lupus treatment, prolonged disease duration in these young patients can result in debilitating psychosocial outcomes and can significantly impact their health-related and general quality of life (QOL). Important domains affected include patient self-esteem, education, employment, healthcare utilization, and mental health. In this review, we examined the barriers that lead to a delay in diagnosing lupus in the pediatric population and addressed cSLE morbimortality and its long-term impact on patient health-related and general QOL.

Health-related quality of life and disability in adults with juvenile idiopathic arthritis: comparison with adult-onset rheumatic diseases

Objective

To compare physical disability, mental health, fatigue and health-related quality of life (HRQoL) across juvenile idiopathic arthritis (JIA) categories in adulthood and between JIA and adult-onset rheumatic diseases.

Methods

Cross-sectional analysis nested in a cohort of adult patients with JIA registered in the Rheumatic Diseases Portuguese Register (Reuma.pt). Physical disability (Health Assessment Questionnaire—Disability Index), mental health symptoms (Hospital Anxiety and Depression Scale), fatigue (Functional Assessment of Chronic Illness Therapy—Fatigue Scale (FACIT-F)) and HRQoL (EuroQol-5D (EQ5D) and Short Form (SF-36)) were compared across JIA categories. Patients with polyarticular JIA and enthesis-related arthritis (ERA) JIA were compared respectively to patients with rheumatoid arthritis (RA) and spondyloarthritis (SpA), matched for gender and age, adjusted for disease duration and activity.

Results

585 adult patients with JIA were included. Comparison across JIA categories showed that persistent oligoarthritis and patients with ERA reported a higher score in EQ5D and SF-36 physical component when compared with other JIA categories.

Polyarticular JIA reported less disability and fatigue than patients with RA (median Health Assessment Questionnaire of 0.25 vs 0.63; p<0.001 and median FACIT-F score 42 vs 40; p=0.041). Polyarticular JIA had also better scores on EQ5D and all domains of SF-36, than patients with RA. Patients with ERA reported less depression and anxiety symptoms (0% vs 14.8%; p=0.003% and 9% vs 21.3%; p=0.002) and less fatigue symptoms (45 vs 41; p=0.01) than patients with SpA.

Conclusion

Persistent oligoarticular JIA and ERA are the JIA categories in adulthood with better HRQoL. Overall, adult polyarticular and patients with ERA JIA have lower functional impairment and better quality-of-life than patients with RA and SpA.

The Impact of Pediatric Rheumatic Diseases on Sexual Health, Family Planning, and Pregnancy

A comprehensive review of reproductive health subtopics, including sexual intercourse, romantic relationships, contraception, sexually transmitted infections, pregnancy, and infertility, as they pertain to patients with pediatric rheumatic diseases and those who care for them.

A Population-based Study of Grade 12 Academic Performance in Adolescents With Childhood-onset Chronic Rheumatic Diseases

OBJECTIVE

The aims of this study were (1) to compare grade 12 standardized test results of patients diagnosed with childhood-onset chronic rheumatic diseases (ChildCRD) and unaffected peers; and (2) to identify factors associated with test results of patients with ChildCRD and unaffected peers.

METHODS

This was a population-based retrospective cohort study. All patients with ChildCRD (juvenile arthritis and systemic autoimmune rheumatic diseases) from the only pediatric rheumatology center in Manitoba for birth cohorts January 1979 to December 1998 were linked to the provincial administrative databases containing records of healthcare use and education outcomes. Patients were matched by age, sex, and postal codes to their peers who did not have ChildCRD. The primary outcomes were the grade 12 Language Arts Achievement Index (LAI) and the Math Achievement Index (MAI) scores. ChildCRD, sociodemographic, and mental health factors were tested for their associations with LAI and MAI scores using multivariable linear regression.

RESULTS

Five hundred and forty-one patients with ChildCRD were matched to 2713 unaffected peers. Patients with ChildCRD had lower LAI and MAI scores compared to their peers. More patients with ChildCRD failed or did not take the language arts (51% vs 41%, P < 0.001) and math (61% vs 55%, P = 0.02) tests. On multivariable analysis, ChildCRD, lower socioeconomic status, younger maternal age at first childbirth, family income assistance, involvement with child welfare services, and mental health morbidities (between ChildCRD diagnosis and standardized testing), were associated with worse LAI and MAI results.

CONCLUSION

This population-based study showed that patients with ChildCRD performed less well than their peers on grade 12 standardized testing, independent of sociodemographic and mental health comorbidities.

Psychiatric disorders in incident patients with juvenile idiopathic arthritis - a case-control cohort study

BACKGROUND

Chronic illness, such as juvenile idiopathic arthritis (JIA), appears to have an impact on the mental health of children and adolescents. The aim of this study was to explore the incidence of mental and behavioural disorders according to age at JIA onset and gender in JIA patients compared to a control population.

METHODS

Information on all incident patients with JIA in 2000-2014 was collected from the nationwide register, maintained by the Social Insurance Institution of Finland. The National Population Registry identified three controls (similar regarding age, sex and residence) for each case. They were followed up together until 31st Dec. 2016. ICD-10 codes of their psychiatric diagnoses (F10-F98) were obtained from the Care Register of the National Institute for Health and Welfare. The data were analysed using generalized linear models.

RESULTS

The cumulative incidence of psychiatric morbidity was higher among the JIA patients than the controls, hazard ratio 1.70 (95% Cl 1.57 to 1.74), p < 0.001. Phobic, anxiety, obsessive-compulsive, stress-related and somatoform disorders (F40-48) and mood (affective) disorders (F30-39) were the most common psychiatric diagnoses in both the JIA patients (10.4 and 8.2%) and the control group (5.4 and 5.1%), respectively. Female patients were more prone to mental and behavioural disorders than males were, and the risk seemed to be higher in patients who developed JIA in early childhood or adolescence.

CONCLUSION

Patients with JIA are diagnosed with mental and behavioural disorders more often than controls, and the age at onset of JIA could have implications for future mental health.

Neuropsychological functioning and academic abilities in patients with juvenile idiopathic arthritis

BACKGROUND

The involvement of the central nervous system is not rare in rheumatoid diseases. Even though children with juvenile idiopathic arthritis (JIA) may face academic difficulties until adulthood, very few studies have evaluated potential cognitive disorders in these patients. The present research aims to thoroughly investigate the cognitive and neuropsychological functioning of these patients.

METHODS

We measured the cognitive profile of JIA patients via their neuropsychological profile, implicit memory and social cognition skills, and estimated their academic performance using reading and mathematics tests. We recruited 21 children with JIA aged 6 to 17 years-old (M = 11.01, SD = 3.30) and 21 healthy children matched in age, gender, academic level (same school class) and socioeconomic status.

RESULTS

Our results showed that the cognitive profile and estimated academic ability of JIA patients are similar to those of their peers. These results support the hypothesis that children with JIA have the same cognitive predispositions to succeed at school as any other pupil.

CONCLUSION

Comparing our results with the existing literature, we propose complementary hypotheses for further research. Longitudinal studies seem to be necessary to understand the psychosocial and cognitive processes involved in the development of children with JIA.

Making Decisions About Stopping Medicines for Well-Controlled Juvenile Idiopathic Arthritis: A Mixed-Methods Study of Patients and Caregivers

OBJECTIVE

Improved treatments for juvenile idiopathic arthritis (JIA) have increased remission rates. We conducted this study to investigate how patients and caregivers make decisions about stopping medications when JIA is inactive.

METHODS

We performed a mixed-methods study of caregivers and patients affected by JIA, recruited through social media and flyers, and selected by purposive sampling. Participants discussed their experiences with JIA, medications, and decision-making through recorded telephone interviews. Of 44 interviewees, 20 were patients (50% ages <18 years), and 24 were caregivers (50% caring for children ages ≤10 years). We evaluated characteristics associated with high levels of reported concerns about JIA or medicines using Fisher's exact testing.

RESULTS

Decisions about stopping medicines were informed by competing risks between disease activity and treatment. Participants who expressed more concerns about JIA were more likely to report disease-related complications (P = 0.002) and more motivated to continue treatment. However, participants expressing more concern about medicines were more likely to report treatment-related complications (P = 0.04) and felt more compelled to stop treatment. Additionally, participants considered how JIA or treatments facilitated or interfered with their sense of normalcy and safety, expressed feelings of guilt and regret about previous or potential adverse events, and reflected on uncertainty and unpredictability of future harms. Decision-making was also informed by trust in rheumatologists and other information sources (e.g., family and online support groups).

CONCLUSION

When deciding whether to stop medicines whenever JIA is inactive, patients and caregivers weigh competing risks between disease activity and treatment. Based on our results, we suggest specific approaches for clinicians to perform shared decision-making regarding stopping medicines for JIA.

The importance of transition from pediatric to adult rheumatology care in juvenile idiopathic arthritis

Introduction: Juvenile idiopathic arthritis (JIA) is the most common rheumatic inflammatory condition in childhood. The long-term morbidity, mortality, and quality of life have improved with the earlier use of disease-modifying drugs (DMARDs) and the availability of biology disease-modifying drugs (bDMARDs). Despite the improvement of treatment, around 50% of the patients reach adulthood with articular and/or extra articular disease activity. A careful planned transition from pediatric to adult care is necessary to reduce the loss of follow-up that is associated with stopping medications, flares, and disability due to untreated arthritis or uveitis.Areas covered: This narrative review provides an overview of the importance of transition in JIA Articles were selected from Pubmed searches.Expert opinion: JIA patients, family, and healthcare workers have to be trained to provide an effective transition plan, based on local and national policies. Important aspects such as expectations, maturation, disease characteristics, disease activity, adherence, disability, and psychological aspects among others have to be considered and addressed during the transition phase to improve self-esteem, self-assurance, and quality of life.

Effects of Childhood-onset Systemic Lupus Erythematosus on Academic Achievements and Employment in Adult Life

OBJECTIVE

Long-term outcome data in adults with childhood-onset systemic lupus erythematosus (cSLE) are limited. Here, we report the effects of cSLE on education, vocation, and employment in a large cohort of adults with cSLE.

METHODS

Patients were seen for a single study visit comprising a structured history and physical examination. Medical records were retrieved to supplement information obtained during the study visit. Education and employment status were assessed by questionnaires. Health-related quality of life (HRQOL) was measured with the 36-Item Short Form Health Survey (SF-36).

RESULTS

One hundred six patients with cSLE (93% female, 73% White), with a median disease duration of 20 years, completed the visit and questionnaires. Almost all patients stated that cSLE had influenced their education, but the level of completed education was similar to the general Dutch population. Half of the patients had adjusted their vocational choice due to the disease. Still, 44% of patients who had finished education did not have a paid job. Of the employed patients, 61% worked part time. Disease damage was equally prevalent in patients with and without paid employment. A high percentage of patients (51%) were declared work disabled, due to disease damage. Patients who did not have paid employment were often work disabled. Both had a negative effect on HRQOL.

CONCLUSION

The effect of cSLE on academic achievements and employment is substantial, despite patients adjusting their educational and vocational choices. To optimize participation in the community, ongoing support is necessary, not only to help patients find suitable education and vocations but also to offer guidance regarding potential adjustments during their career.

Longitudinal Health Status from Early Disease to Adulthood and Associated Prognostic Factors in Juvenile Idiopathic Arthritis

Objective.

To describe the longitudinal health status from childhood to adulthood in patients with juvenile idiopathic arthritis (JIA), compare outcomes after 19 years with those of controls, and identify early predictors of physical functioning, pain, and physical health-related quality of life (HRQOL).

Methods.

Between 1995–2003, 96 patients with JIA (mean 6.1 ± 4.0 yrs, 67% female) were assessed within 18 months of diagnosis and every 6 months for the next 3 years with measures of JIA disease activity, physical functioning, pain, fatigue, and well-being. They were reassessed a mean of 18.9 ± 1.5 years later (mean age 25.1 ± 4.2 yrs) with measures of physical disability [Health Assessment Questionnaire–Disability Index (HAQ-DI)], pain, fatigue, well-being (visual analog scale), and physical and mental health-related quality of life (HRQOL; Medical Outcomes Study 12-item Short Form Health Survey, version 2).

Results.

During the first 3 years, physical disability improved (p < 0.001) and the proportion of patients reporting best possible well-being increased (p = 0.013), while pain and fatigue did not change. At 3- and 19-year followups, patients had similar levels of physical disability, well-being, and pain, but fatigue increased (p = 0.016) and the number of patients with HAQ-DI = 0 decreased (p = 0.001). After 19 years, patients had worse pain and physical HRQOL than controls (p < 0.001). Pain, active joints, and physical disability during the first 3 years were associated with more disability and pain and worse physical HRQOL after 19 years (p < 0.001–0.047).

Conclusion.

Patients with JIA reported similar physical functioning, well-being, and pain at 3- and 19-year followups, but more fatigue after 19 years. Patients also had worse health status than controls after 19 years. Pain, active joints, and physical disability were early predictors of unfavorable outcomes.

Prediction of disease relapse in a cohort of paediatric patients with localized scleroderma

BACKGROUND

Localized scleroderma (LS) is an autoimmune condition of the skin and underlying tissue. Active or recurring disease can lead to cumulative tissue damage, especially in paediatric-onset disease.

OBJECTIVES

To highlight the rate of relapse of LS activity in a cohort of paediatric patients and to evaluate for potential clinical and laboratory predictors of disease relapse.

METHODS

Clinical and laboratory data were gathered prospectively. Patients were categorized as experiencing relapse or not, and clinical and laboratory parameters were compared. A logistic regression was fit to predict odds of relapse while controlling for multiple predictors. A subgroup of patients was also evaluated to determine the average time from treatment completion to relapse.

RESULTS

Seventy-seven patients were followed for the identified study duration of > 2 years and had achieved disease remission, with 35 (45%) experiencing LS relapse. Patients who were older at disease onset, antinuclear antibody (ANA) positive and without an extracutaneous manifestation (ECM) were more likely to relapse. All three variables remained significant in the multivariable logistic regression model. Results of the subgroup mirrored the larger sample. The average time between treatment completion and relapse was 21 months.

CONCLUSIONS

Assessment of patients with LS experiencing a relapse of disease activity has shown older age of initial LS onset and ANA positivity to be potential markers for risk of relapse. Patients meeting these parameters may require greater clinical vigilance. The presence of one or more ECM may be protective. Clinicians treating patients with LS should provide significant long-term follow-up to monitor for relapse.

Transitions in Rheumatic Disease: Pediatric to Adult Care

Although it has been widely acknowledged for more than two decades that transition from pediatric to adult care is a vulnerable time for adolescents and young adults with rheumatic diseases, current primary and subspecialty care transition and transfer processes remain inadequate. Barriers to improving transition include complex health care systems, neurodevelopmental challenges of adolescents and young adults, and insufficient transition-related education and resources for health care providers. Standardized, evidence-based transition interventions are sorely needed to establish best practices. Quality improvement approaches such as the Six Core Elements of Health Care Transition offer opportunities to improve transition care for teens and young adults.

A new biopsychosocial and clinical questionnaire to assess juvenile idiopathic arthritis: JAB-Q

OBJECTIVE

To create a new multidimensional questionnaire for the assessment of juvenile idiopathic arthritis (JIA) patients in standard clinical practice and study the validity and reliability of this questionnaire.

METHODS

The Juvenile Arthritis Biopsychosocial and Clinical Questionnaire (JAB-Q) was created using the Delphi technique and consensus conference following an initial literature search. The questionnaire has three parts including a clinician form, child form and parent form. This is a patient/parent-centered outcome tool, which helps us to evaluate the biopsychosocial aspects of the patient, including disease activity, posture, functional and psychosocial status, fatigue, and performance in school. From January 2015 to January 2018, 6-18 years old children with JIA were enrolled in the study. The previously validated questionnaires were also applied to each participant to validate the JAB-Q: Juvenile Idiopathic Disease Arthritis Score (JADAS) and Childhood Health Assessment Questionnaire (CHAQ), and the Family Impact Questionnaire (FIS). The same questionnaire was re-administered after one week to assess the test-retest reliability in randomly selected 50 children and their parents.

RESULTS

A group of experts were invited to the Delphi survey. After the Delphi tours, the final form of the questionnaire containing three parts as clinician form, child form and parent form was created. This tool was applied to 310 JIA patients and their parents. The children and parents easily handled the JAB-Q and filled the forms in around 10-15 min. The validity of the clinician, child and parents' forms were assessed by the JADAS, CHAQ, and FIS, respectively. The validity of these three scales were determined as moderate. In addition, the test-retest reliability of the clinician, child and parents' forms were considerably high.

CONCLUSION

JAB-Q is a valid and reliable multidimensional biopsychosocial outcome tool that can be used routinely in clinical practice of pediatric rheumatology. The main advantage of this tool is incorporation of patients' and parents' perspectives separately while providing a practical and standard setting for the clinician's evaluation. However, further validation of this tool in an independent cohort is needed to improve its applicability.

Physical Functioning, Pain, and Health-Related Quality of Life in Adults With Juvenile Idiopathic Arthritis: A Longitudinal 30-Year Followup Study

OBJECTIVE

To describe physical functioning, pain, and health-related quality of life (HRQoL) in adults with juvenile idiopathic arthritis (JIA), investigate changes over time, and identify predictors of poorer HRQoL after 30 years of disease.

METHODS

Patients (n = 176) clinically examined after 15 years were reassessed using the Health Assessment Questionnaire disability index (HAQ DI), the visual analog scale pain subscale (VAS pain), and the Medical Outcomes Study Short Form 36 (SF-36) after 23 years and 30 years. Patients with signs of active disease after a minimum of 15 years were clinically examined again at 30 years. Patients were compared to matched controls.

RESULTS

At the 30-year followup, 82 patients (47%) had HAQ DI scores >0, and the median VAS pain score in patients was 0.6 (range 0-10). Patients had lower SF-36 physical component summary (PCS) scores compared with controls (P < 0.001), and this was evident for patients both with and without clinical remission (P ≤ 0.01). No group differences were found in SF-36 mental component summary scores. Patients also scored worse than controls on all SF-36 subscales (P ≤ 0.01) except mental health. PCS scores worsened significantly between the 15- and 30-year followup time points (P = 0.001). Worse HAQ DI, VAS pain, and patient's global assessment of well-being scores, and receiving disability/social living allowance at 30 years, were correlated with lower PCS scores. Worse HAQ DI, patient's global assessment of well-being, and VAS fatigue scores at 15-year followup predicted lower PCS scores at 30-year followup.

CONCLUSION

JIA had a detrimental effect on physical HRQoL as measured by the PCS of the SF-36. The strongest correlates were physical disability, pain, fatigue, well-being, and receiving disability/social living allowance.

Sociocultural Considerations in Juvenile Arthritis: A Review

PROBLEM

Juvenile Arthritis (JA) is one of the most common autoimmune diseases in children. A variety of sociocultural factors that influence health outcomes in children with JA have been examined in previous research. However, clinical guidelines to guide the care of these children lack support because this research has not been systematically examined and synthesized.

ELIGIBILITY CRITERIA

Primary research articles from five internet databases were included if they were peer-reviewed articles in English of studies conducted in the U.S. or Canada and referenced one or more determinants of health, quality of life, socioeconomic status, or health disparities in children with JA.

SAMPLE

The final sample included 16 articles representing 2139 children and 939 parents.

RESULTS

Topics covered in the studies included medication compliance, electronic medical records, environmental risk factors, economic hardship, parental coping, leisure activities, and their effects on patient outcomes including disability and quality of life. Patients with Medicaid experienced more severe outcomes than patients with private insurance despite equivalent levels of healthcare utilization. Other important topics, such as effects of the physical environment and alcohol use, were missing from the literature.

CONCLUSIONS

Five categories of health determinants were found to influence outcomes: biology, individual behaviors, social environment, physical environment, and health services. Disparities continue to exist for racial and ethnic minority children with JA and those of low socioeconomic status.

IMPLICATIONS

Sociocultural factors should be taken into consideration when developing care plans, research studies, and policies in order to remove barriers and promote the best outcomes for this vulnerable population.

Education and employment in patients with juvenile idiopathic arthritis - a standardized comparison to the German general population

BACKGROUND

Although several studies show that JIA-patients have significantly lower employment rates than the general population, the research on educational and occupational attainments in patients with juvenile idiopathic arthritis (JIA) remain conflicting most likely due to small sample sizes. Therefore, aim of this study is to compare the educational achievements and employment status of 3698 JIA-patients with the German general population (GGP).

METHODS

"SEPIA" was a large cross-sectional study on the current status of a historic cohort of JIA-patients treated in a single center between 1952 and 2010. For the analyses of education and employment a sub-cohort was extracted, including only adult cases with a confirmed diagnosis of JIA (N = 2696). Participants were asked to fill out a standardized written questionnaire on education and employment. Outcome measures (education/unemployment) were directly standardized to the GGP using data obtained from the National Educational Panel Study 2013 (N = 11,728) and the German Unemployment Statistics 2012 of the Federal Statistical Office (N = 42,791,000).

RESULTS

After age- and sex-standardization, 3% (95% Confidence Interval 1.9 to 4.1%) more of the JIA-patients (26%) than of the GGP (23%) had only reached primary education. In contrast, parents of JIA-patients had similar levels of education as parents in the GGP. With a standardized difference of 0.2% (95% CI: 0.16 to 0.19%), the unemployment rate in JIA-patients was slightly, but not significantly higher than in the GGP. Stratifying for disease duration and the current treatment status, differences were confirmed for persons diagnosed before 2001, whilst for patients diagnosed after 2000, differences were found only in JIA-patients with ongoing disease. Medium and high educational achievements did not differ statistically significant between JIA patients and the GPP.

CONCLUSION

Educational achievements in German JIA-patients are significantly lower than in the GGP. Furthermore we were able to identify a slightly higher level of unemployment, especially in those with still under treatment and longer disease duration. Better treatment options as well as further development of social support programs might help to overcome this lifelong secondary effect of JIA.

A survey of national and multi-national registries and cohort studies in juvenile idiopathic arthritis: challenges and opportunities

BACKGROUND

To characterize the existing national and multi-national registries and cohort studies in juvenile idiopathic arthritis (JIA) and identify differences as well as areas of potential future collaboration.

METHODS

We surveyed investigators from North America, Europe, and Australia about existing JIA cohort studies and registries. We excluded cross-sectional studies. We captured information about study design, duration, location, inclusion criteria, data elements and collection methods.

RESULTS

We received survey results from 18 studies, including 11 national and 7 multi-national studies representing 37 countries in total. Study designs included inception cohorts, prevalent disease cohorts, and new treatment cohorts (several of which contribute to pharmacosurveillance activities). Despite numerous differences, the data elements collected across the studies was quite similar, with most studies collecting at least 5 of the 6 American College of Rheumatology core set variables and the data needed to calculate the 3-variable clinical juvenile disease activity score. Most studies were collecting medication initiation and discontinuation dates and were attempting to capture serious adverse events.

CONCLUSION

There is a wide-range of large, ongoing JIA registries and cohort studies around the world. Our survey results indicate significant potential for future collaborative work using data from different studies and both combined and comparative analyses.

'It might hurt, but you have to push through the pain': Perspectives on physical activity from children with juvenile idiopathic arthritis and their parents

Our primary objective was to gather perspectives of children diagnosed with juvenile idiopathic arthritis (JIA) and their parents as they relate to physical activity (PA) participation. To do so, we conducted a study on 23 children diagnosed with JIA and their parents ( N = 29). We used convenience sampling to recruit participants and qualitative method- logies (one-on-one semi-structured interviews). We adopted a five-step framework analysis to categorize data into themes. Children and their parents described factors that act to facilitate or hinder PA participation. Pain was the most commonly highlighted PA barrier described by children and their parents. However, children who were newly diagnosed with JIA and their parents were more likely to highlight pain as a barrier than were child/parent dyads where children had been previously diagnosed.

Friends United: An Evaluation of an Innovative Residential Self-Management Programme in Adolescent Rheumatology

Independence in activities of daily living, self-advocacy and peer support are important aspects of adolescent development. These skills are potentially affected by chronic rheumatic diseases and are worthy of attention by occupational therapists and other members of the multidisciplinary team.

An innovative 4-day residential programme for young people diagnosed with chronic rheumatic disease, known as the ‘Independence Break’, was evaluated in order to determine its perceived benefits. The participants were invited to complete a brief evaluation form immediately after the trip to determine the benefits of participation in the programme. The levels of continuing social contact within the group were established 4 months later during a subsequent telephone call.

Thirty young people (median age 14 years) attended the 4-day programme and reported friendship and improved performance in activities of daily living as the major benefits. The majority stayed in touch with at least one other person, with more girls staying in touch than boys. The preferred method of communication was text messaging.

Overall, the programme was perceived to be a valuable experience and offered the young people an opportunity to develop informal peer support networks. The potential of text messaging within adolescent rheumatology is also highlighted.

The Prevocational and Early Employment Needs of Adolescents with Juvenile Idiopathic Arthritis: The Adolescent Perspective

The purpose of this study was to explore the prevocational needs of adolescents with juvenile idiopathic arthritis (JIA) from their own perspectives.

A focus group discussion was undertaken with eight adolescents with JIA (14.2–16.6 years) attending one United Kingdom hospital. The topics of interest were (i) attitudes towards education, prevocational readiness and employment in relation to JIA; (ii) perceived barriers; (iii) coping strategies; and (iv) preferred sources of support. The data were analysed according to standardised procedures that included data reduction, data display, conclusion drawing and conclusion verifying.

The provision of vocational support for young people with JIA was reported to be uncoordinated, limited and unresponsive to individual needs. A recurrent theme was that professionals generally underestimated adolescents' educational and vocational potential. This was felt to be true of teachers, careers advisers, admissions personnel at colleges and universities and potential employers. Most adolescents worried about discrimination and those in whom the JIA was not visible felt a dilemma about disclosure to potential employers.

The current framework of careers advice appeared to have failed the adolescents in this study who, in the absence of satisfactory support, found themselves consulting health professionals instead. Greater careers advice support for adolescents and professionals is warranted.

Population-based study of outcomes of patients with juvenile idiopathic arthritis (JIA) compared to non-JIA subjects

OBJECTIVE

Evaluate healthcare utilization and occurrence of comorbidities in a population-based cohort of patients of juvenile idiopathic arthritis (JIA) with an age- and sex-matched comparator group.

METHODS

Prevalent cases of JIA in 1994-2013 were identified in Olmsted County, Minnesota, along with age- and sex-matched non-JIA comparators. Surgeries, hospitalizations, pregnancies, and comorbidities were identified by medical record review. Poisson methods were used to generate rate ratios (RR) with 95% confidence intervals (CI) to compare outcomes between JIA and non-JIA cohorts separately during childhood (age < 18 years) and adulthood (age ≥ 18 years).

RESULTS

A total of 89 JIA and 89 non-JIA comparators were identified [64% female; mean (SD) age 8.6 (5.1) years at JIA incidence/index date and mean follow-up in childhood 6.3 (4.4) years for JIA; similar for comparators]. Among them, 38 pairs had follow-up into adulthood with mean follow-up of 8.0 (5.5) years for JIA. Children with JIA were more likely to have joint surgery (RR = 3.93, 95% CI: 1.18-24.94), non-joint surgery (RR = 1.90, 95% CI: 1.05-3.67), and hospitalizations (RR = 2.25, 95% CI: 1.04-5.53) than non-JIA comparators. As adults only joint surgeries remained significantly different (RR = 8.5, 95% CI: 2.27-120.1). Depression during childhood was more common in JIA (RR = 2.49, 95% CI: 1.01-6.13). There were no differences in educational achievement, employment status, or pregnancy outcomes between the 2 groups.

CONCLUSIONS

In a population-based cohort, inpatient healthcare utilization is higher for patients with JIA including surgery and hospitalization during childhood but not extending into adulthood. Understanding long-term comorbidities and healthcare needs for patients with JIA is necessary to provide comprehensive care.

Reproductive trends in females with inflammatory joint disease

Background

The study assessed birth trends per decade in offspring of females with inflammatory joint diseases (IJD) compared with women without IJD.

Methods

This retrospective cohort study is based on data from the Medical Birth Registry of Norway from 1967 to 2009. We investigated singleton births in females with IJD (n = 7502) and compared with births from the general population (n = 2 437 110). Four periods were examined: 1967–79, 1980–89, 1990–99 and 2000–09. In the logistic regression analysis adjustments were made for maternal age at delivery and birth order. Odds ratios were obtained for the associations between IJD and birth outcome for each period.

Results

Females with IJD had in average 65 deliveries / year (0.08 % of all births) in the 1970ies and 274 deliveries / year (0.5 % of all births) from 2000 to 2009. Adjusted Odds ratios (aOR) for newborns small for gestational age were 1.5 (95 % CI 1.2, 1.9) in the earliest and 1.1 (95 % CI 0.9, 1.2) in the last period. Correspondingly, for birth weight < 2500 grams aOR decreased from 1.4 (95 % CI 1.0, 1.9) to 1.1 (95 % CI 0.9, 1.4). For preterm birth aOR was 1.1 (95 % CI 0.8, 1.5) in the first and 1.3 (95 % CI (1.1, 1.5) in the last period.

Conclusion

An increasing number of births among females with IJD were observed in the study period. Birth weights of newborns of IJD women approached to birth weights in the general population, but preterm birth remained a problem.

Long-Term Health-Related Quality of Life in German Patients with Juvenile Idiopathic Arthritis in Comparison to German General Population

Objective

Aims of the study were to investigate health-related quality of life (HRQOL) in adult patients with former diagnosis of Juvenile Idiopathic Arthritis (JIA), to compare their HRQOL with the general population and to identify factors related to a poor outcome.

Methods

In 2012, a cross-sectional survey was performed by mailing a questionnaire to a large cohort of former and current patients of the German Centre for Rheumatology in Children and Adolescents. Only adult patients (≥18 years) with a diagnosis compatible with JIA were included (n = 2592; response 66%). The questionnaire included information about HRQOL (EQ5D), disease-related questions and socio-demographics. Prevalence and 95% confidence intervals (CI) of problems with mobility, self-care, usual activities, pain and anxiety/depression were standardized to the German general population. Factors associated with low HRQOL in JIA patients were identified using logistic regression models.

Results

Sixty-two percent of the study population was female; age range was 18–73 years. In all dimensions, JIA patients reported statistically significantly more problems than the general population with largest differences in the pain dimension (JIA patients 56%; 95%CI 55–58%; general population 28%; 26–29%) and the anxiety/depression dimension (28%; 27–29% vs. 4%; 4–5%). Lower HRQOL in JIA patients was associated with female sex, older age, lower level of education, still being under rheumatic treatment and disability.

Conclusions

HRQOL in adult JIA patients is considerably lower than in the general population. As this cohort includes historic patients the new therapeutic schemes available today are expected to improve HRQOL in future.

Birth Outcomes in Women with a History of Juvenile Idiopathic Arthritis

OBJECTIVE

To determine whether children born to women who had juvenile idiopathic arthritis (JIA) had more adverse birth outcomes than children born to mothers who never had JIA.

METHODS

Our cohort study used data from physician billing and hospitalizations covering the province of Quebec, Canada. We identified all women with JIA with a first-time birth between January 1, 1983, and December 31, 2010, and assembled a control cohort of first-time mothers without JIA from the same administrative data, matching 4:1 for date of first birth, maternal age, and area of residence. We compared outcomes (stillbirth, prematurity, small for gestational age, and major congenital anomalies) in the JIA versus non-JIA groups using logistic regression.

RESULTS

Mean age at delivery was 24.7 years in the JIA group (n = 1681) and 25.0 years for the non-JIA group (n = 6724). Women who had JIA were at higher risk for a premature baby [adjusted relative risk (RR) 1.20, 95% CI 1.01-1.42], a baby small for gestational age (adjusted RR 1.19, 95% CI 1.04-1.37), and a child with a congenital malformation (adjusted RR 6.51, 95% CI 5.05-8.39). Neural tube defects were higher in the JIA offspring: 1.61% (95% CI 1.11-2.33) versus 0.03% (95% CI 0.01-0.11) in the non-JIA group, as were congenital heart defects: 1.07% (95% CI 0.68-1.69) versus 0.58% (95% CI 0.42-0.79).

CONCLUSION

Most women with JIA will deliver a normal baby, even though they are at higher risk for having a child with adverse birth outcomes. Research is needed to understand pathophysiologic mechanisms and to investigate the effects of medications during childhood and youth on future birth outcomes.

Analysis of employment rate and social status in young adults with childhood-onset rheumatic disease in Catalonia

BACKGROUND

Rheumatic diseases of childhood, in particular juvenile idiopathic arthritis, are chronic conditions associated with considerable morbidity and mortality that can have repercussions on aspects of adult life. The aim of this study was to determine the employment rate and social status of patients with childhood-onset rheumatic disease attending a pediatric rheumatology transition unit.

METHODS

A census was taken of patients seen in the Pediatric Rheumatology Transition Unit of Hospital Vall d'Hebron (Barcelona, Spain). We collected demographic and clinical variables and determined the patients' functional capacity. All patients seen during the period of September to December 2013 underwent a survey containing items related to their social situation, maximum academic level achieved, and working life. Correlations were sought between clinical variables associated with a poor prognosis and the patients' job performance. The data were analyzed and compared with those of an age-matched cohort from the general population of Catalonia.

RESULTS

Of 130 patients included in the census, 96 responded to the survey. Steinbrocker grade III and IV disability (poorer functional capacity) (p = 0.0025) and longer disease duration (p = 0.017) were significantly related to greater difficulty getting a job. Patients with grade III and IV disability and those with more severe disease showed trends to having more problems carrying out work-related tasks. Our cohort included a higher percentage of students than the age-matched comparison population (50 % vs 24 %, respectively) (p = 0.0001); 82 % of patients had completed studies beyond the compulsory education level. The employment rate was lower in our patient cohort than in the comparison cohort (38.3 % vs 59.9 %) (p = 0.0001), whereas the percentage of unemployed was similar. Patients with milder disease had a higher probability of living with their parents up to a later age (OR = 3.2, 95 % CI 0.38-6.15; p = 0.029).

CONCLUSIONS

Despite the advances in treatment, some patients with childhood-onset rheumatic disease encounter difficulties in their later social and working life. In our cohort, the time period needed to complete their studies tended to be longer, and incorporation into the workforce occurred at a later age. Our findings reinforce the idea that psychological support and vocational guidance are important factors in the management of these patients.

The impact of arthritis on the early employment experiences of young adults: A literature review

BACKGROUND

Young adulthood is an important transitional life phase that can determine a person's career trajectory. To date, little research has examined the influence of arthritis on early work experiences.

OBJECTIVES

This literature review aims at examining the impact of arthritis on the early career phase of young adults and identifying the barriers to employment.

METHODS

Two independent reviewers searched bibliographic databases for arthritis conditions and a series of employment-related keywords and subject headings. Information on authors, publication year; study design, sample characteristics (e.g., number of participants, age, gender, arthritis type); work outcomes measured; and specific barriers to employment was recorded.

RESULTS

Nine studies were uncovered in the review. All studies examined young people with juvenile arthritis (9 of 9 studies) and consisted of sample sizes with less then 150 participants (6 of 9 studies) who were primarily recruited from clinics (7 of 9 studies). All were cross-sectional designs. Employment status was primarily examined and ranged from 11% to 71%. Although not always statistically significant, young adults with arthritis were less likely to be employed when compared to their healthy peers. Greater disease severity, less educational attainment and being female were related to not participating in paid work.

CONCLUSION

This review brings to light the paucity of studies examining the early employment experiences of young adults with arthritis. There is a need to expand research to contribute to recommendations for sustained and productive employment across the working life course.

Impact of JIA on parents' work absences

OBJECTIVE

Children with JIA have long-term morbidity and require extensive parental assistance. This study aimed to evaluate the impact of having a child with JIA on parents' missed work time, which can lead to decreased work productivity.

METHODS

The Truven Health MarketScan Commercial Database (2000-9) was accessed to identify a cohort of parents having a child with newly diagnosed JIA. For comparison, a cohort of parents having no children with JIA was identified and matched with the preceding cohort. Parents' work absences were analysed using descriptive statistics and multivariable regression. Estimates were weighted to be generalizable to the US employer-sponsored insurance population.

RESULTS

The study identified 108 parents having a child with newly diagnosed JIA (mean age 42.5 years), representing an estimated 3335 (weighted) parents nationally. Most of them were from the South (45%), male (71%) and employed in the transportation and utilities industry (58%). The demographic characteristics of the control cohort of parents were generally similar. Children with JIA (mean age 10.6 years) represented an estimated 3528 cases nationally. The mean number of reported missed work-time hours was 281.81 (s.e. 40.50) in a 9 year period for parents having a child with JIA compared with other parents 183.36 (28.55). Work-time loss was significantly related to having a child with JIA, sex and geographical region of residence. Parents having a child with JIA were 2.78 times more likely to report work-time loss [odds ratio (OR) 2.78 (95% CI 1.47, 5.26)] than those having no children with JIA.

CONCLUSION

Parents having a child with JIA report significant work-time loss compared with parents with no children having JIA, particularly during the year following the child's diagnosis.

Assessment and management of pain in juvenile idiopathic arthritis

Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease in childhood. Persistent pain is the most common and distressing symptom of JIA, and pain in childhood arthritis is multifactorial. Children and adolescents with persistent pain due to JIA experience significantly more problems with physical, emotional, social, and school functioning than healthy individuals. Assessment of pain at each office visit is the cornerstone of effective pain management and should include an evaluation of pain intensity, interference, and coping. Following the biopsychosocial model of pain management, a multi-modal approach is recommended for pain control in children with arthritis. Pharmacologic strategies for the treatment of pain in JIA include aggressive treatment of the underlying disease as well as the use of acetaminophen and systemic and topical non-steroidal anti-inflammatory drugs for persistent mild pain. Opioids can be considered in the case of moderate to severe persistent pain. Physical therapies and psychological interventions such as cognitive behavioral therapy are also key components of pain management in JIA.

Disease progression into adulthood and predictors of long-term active disease in juvenile idiopathic arthritis

OBJECTIVES

To describe disease activity 30 years after disease onset in a previously studied cohort of patients with juvenile idiopathic arthritis (JIA) and reveal predictors of long-term active disease.

METHODS

Patients with JIA, first referred 1980-1985 and re-examined 15 and 23 years after onset, were invited to attend. All 176 patients were assessed by questionnaires. Patients with signs of active disease at 15 years or later also came to a clinical re-examination (n=90). Disease activity was assessed by the clinical juvenile arthritis disease activity score (JADAS3) and by the criteria for remission in JIA, and health status by Health Assessment Questionnaire (HAQ) and Medical Outcome Study 36-item Short Form Health Survey (SF-36).

RESULTS

At 30-year follow-up, 59% of the patients were in clinical remission off medication, 7% were in remission on medication and 34% had active disease. 70% of the patients were in the same category of disease activity at 15 and 30 years. The JADAS3 was ≤2.0 in 54%, 2.1-4.5 in 18% and >4.5 in 28%. HLA-DRB1*01, physician's global assessment and a short total time in remission at 15 years, predicted active disease. Physician's global assessment also predicted a JADAS3 >4.5. From 15 to 30 years (n=90), physician's global assessment, number of active joints, erythrocyte sedimentation rate and C reactive protein improved significantly, but patient's global assessment, HAQ and SF-36 did not.

CONCLUSIONS

41% of the patients with JIA had active disease or were on medication after 30 years and 28% had a high symptom state. Remission rates and patient-reported health status at 15 years were comparable with rates at 30 years.

Transitioning to Employment with a Rheumatic Disease: The Role of Independence, Overprotection, and Social Support

Objective.

To examine perceived independence, overprotection, and support, and their association with the employment participation of young adults with rheumatic disease.

Methods.

One hundred and forty-three young adults, ages 18 to 30 years, with systemic lupus erythematosus (54.5%) and juvenile arthritis (45.5%) completed a 30-min online questionnaire of their work and education experiences. Information collected was demographic, health (e.g., pain, fatigue, disease activity), work context (e.g., career satisfaction, helpfulness of job accommodation/benefits, and workplace activity limitations), and psychosocial (e.g., independence, social support, and overprotection). Log-Poisson regression analysis examined factors associated with employment status.

Results.

Over half of respondents were employed (59%) and 26% were enrolled in school. Respondents reported moderate to high perceptions of independence and social support. However, 27% reported that “quite a bit” to “a great deal” of overprotection characterized their relationships with those closest to them. At the bivariate level, employed participants and those indicating greater perceived independence reported greater social support and less overprotection. Multivariable analysis revealed that being employed was associated with older age, more job accommodations/benefits perceived as being helpful, and greater perceived independence.

Conclusion.

This is one of the first studies examining the employment of young adults with rheumatic diseases. Findings highlight the importance of psychosocial perceptions such as independence and overprotection, in addition to support related to working. Additional research is needed to better understand the role of those close to young adults with rheumatic diseases in supporting independence and encouraging employment.

Impact of a telenursing service on satisfaction and health outcomes of children with inflammatory rheumatic diseases and their families: a crossover randomized trial study protocol

BACKGROUND

Pediatric rheumatic diseases have a significant impact on children's quality of life and family functioning. Disease control and management of the symptoms are important to minimize disability and pain. Specialist clinical nurses play a key role in supporting medical teams, recognizing poor disease control and the need for treatment changes, providing a resource to patients on treatment options and access to additional support and advice, and identifying best practices to achieve optimal outcomes for patients and their families. This highlights the importance of investigating follow-up telenursing (TN) consultations with experienced, specialist clinical nurses in rheumatology to provide this support to children and their families.

METHODS/DESIGN

This randomized crossover, experimental longitudinal study will compare the effects of standard care against a novel telenursing consultation on children's and family outcomes. It will examine children below 16 years old, recently diagnosed with inflammatory rheumatic diseases, who attend the pediatric rheumatology outpatient clinic of a tertiary referral hospital in western Switzerland, and one of their parents. The telenursing consultation, at least once a month, by a qualified, experienced, specialist nurse in pediatric rheumatology will consist of providing affective support, health information, and aid to decision-making. Cox's Interaction Model of Client Health Behavior serves as the theoretical framework for this study. The primary outcome measure is satisfaction and this will be assessed using mixed methods (quantitative and qualitative data). Secondary outcome measures include disease activity, quality of life, adherence to treatment, use of the telenursing service, and cost. We plan to enroll 56 children.

DISCUSSION

The telenursing consultation is designed to support parents and children/adolescents during the course of the disease with regular follow-up. This project is novel because it is based on a theoretical standardized intervention, yet it allows for individualized care. We expect this trial to confirm the importance of support by a clinical specialist nurse in improving outcomes for children and adolescents with inflammatory rheumatisms.

Educational and vocational outcomes of adults with childhood- and adult-onset systemic lupus erythematosus: nine years of followup

OBJECTIVE

To compare educational and vocational outcomes among adults with childhood-onset systemic lupus erythematosus (SLE) and adult-onset SLE.

METHODS

We used data derived from the 2002–2010 cycles of the Lupus Outcomes Study, a longitudinal cohort of 1,204 adult subjects with SLE. Subjects ages 18–60 years living in the US (n = 929) were included in the analysis and were classified as childhood-onset SLE if age at diagnosis was <18 years (n = 115). Logistic regression was used to assess the unadjusted and adjusted effect of childhood-onset SLE, sex, race/ethnicity, baseline age, urban or rural location, and US region on the likelihood of completing a bachelor's degree. Generalized estimating equations were used to assess the effect of childhood-onset SLE, demographics, education, and disease-related factors on the odds of employment, accounting for multiple observations over the study period.

RESULTS

Subjects with childhood-onset SLE were on average younger (mean ± SD 29 ± 10 years versus 44 ± 9 years), with longer disease duration (mean ± SD 15 ± 10 years versus 11 ± 8 years). Subjects with adult-onset SLE and childhood-onset SLE subjects were equally likely to complete a bachelor's degree. However, subjects with childhood-onset SLE were significantly less likely to be employed, independent of demographic and disease characteristics (odds ratio 0.62, 95% confidence interval 0.42–0.91).

CONCLUSION

While subjects with SLE are just as likely as those with adult-onset SLE to complete college education, childhood-onset SLE significantly increases the risk of not working in adulthood, even when controlling for disease and demographic factors. Exploring reasons for low rates of employment and providing vocational support may be important to maximize long-term functional outcomes in patients with childhood-onset SLE.

Longitudinal course and risk factors for fatigue in adolescents: the mediating role of sleep disturbances

OBJECTIVES

This study (1) examines fatigue over 1 year in adolescents with chronic pain (n = 61) and depressive disorders (n = 51) compared with healthy adolescents (n = 60), (2) identifies longitudinal risk factors, and (3) tests sleep disturbances as a mediator between depression and fatigue.

METHODS

Adolescents completed questionnaires at baseline, 6, and 12 months. Mixed effects models examined associations between risk factors and fatigue; structural equation modeling assessed contemporaneous and longitudinal mediation.

RESULTS

Results revealed fatigue persisted at 1 year follow-up, with adolescents in the clinical samples experiencing greater fatigue than healthy youth at all time points (ps < .001). Age, baseline depression, and baseline sleep disturbances predicted longitudinal fatigue for the total sample (ps < .05), with variation in predictors by subgroup. Sleep quality mediated the contemporaneous effects of depression on fatigue in the clinical samples (ps < .05).

CONCLUSIONS

Findings underscore the longitudinal course of fatigue and suggest that improving sleep disturbances may reduce fatigue in clinical samples.

Health and identity: Self-positioning in adolescent chronic fatigue syndrome and juvenile idiopathic arthritis

The aim of this study is to gain more insight into basic aspects of identity, in relation to adolescent chronic fatigue syndrome (CFS) and juvenile idiopathic arthritis (JIA). In dialogical self theory, identity is regarded as incorporating multiple self-positions, such as 'I as tired', 'I as pessimistic', or 'I as decisive'. Physical and psychosocial impairment might alter the organization of these self-positions. The Personal Position Repertoire procedure, a quantitative method to analyse the prominence of self-positions, the Child Health Questionnaire, assessing health-related functioning, and the Checklist Individual Strength, measuring fatigue, were completed by 42 adolescents with CFS, 37 adolescents with JIA and 23 healthy teenagers. Adolescents with JIA report impaired physical functioning and general health. However, they position themselves very similar to healthy teenagers - i.e. as strong and healthy. While this self-positioning approach might be adequate and sustainable in adolescence, it could prove too strenuous to maintain throughout adult life. Adolescents with CFS, besides indicating severe physical difficulties, also report more psychosocial problems. They position themselves as significantly less strong and more unwell. With this emphasis on positions relating to their illness, there seems to be little room left for stronger positions. It is regarded of clinical importance to address these issues in this crucial developmental period.

Disease Course, Outcome, and Predictors of Outcome in a Population-based Juvenile Chronic Arthritis Cohort Followed for 17 Years

Objective.

To investigate disease course, outcome, and predictors of outcome in an unselected population-based cohort of individuals diagnosed with juvenile chronic arthritis (JCA) followed for 17 years.

Methods.

The cohort consisted of 132 incidence JCA cases identified 1984–1986 according to EULAR criteria. At 5-year followup, 129 individuals underwent joint assessment, laboratory measurements, radiographic examination, and medication and functional assessment. At 17-year followup, 86 were examined with joint assessment, laboratory measurements, medication assessment, Health Assessment Questionnaire (HAQ), Keitel functional test (KFT), and Medical Outcomes Study Short Form-36 (SF-36).

Results.

At 17-year followup, 40% were in remission, 44% changed subgroups, median HAQ score was 0.0 (range 0.0–1.5), and median KFT was 100 (range 54–100). SF-36 scores were significantly lower compared to a reference group. Thirty-nine percent of those in remission at 5-year followup were not in remission at 17-year followup. In multivariate analyses of variables from the 17-year followup: remission was predicted by remission at 5-year followup (OR 4.8); HAQ > 0 by rheumatoid factor (RF)-positivity at 5-year followup (OR 3.6); KFT < 100 by nonremission (OR 11.3); and RF-positivity (OR 5.6) at 5-year followup; and the SF-36 physical component summary score above average of the reference group by remission at 5-year followup (OR 5.8).

Conclusion.

This longterm study of 86 individuals with JCA showed large variability of disease courses and of impaired health-related quality of life. Sixty percent were not in remission at 17-year followup. Longterm outcome was best predicted by and associated with characteristics at 5-year followup rather than those at onset.

Pregnancy outcomes in women with juvenile idiopathic arthritis: a population-based study

OBJECTIVE

The aim of this study is to describe pregnancy outcomes among women with JIA.

METHODS

Women who gave birth in New South Wales (NSW), Australia, were linked to hospital discharge records from 2000 to 2010. Women with an ICD-10-AM code of M08 or M09 in the hospital records were considered to have JIA. Logistic regression was used to calculate odds ratios for pregnancy outcomes and the lack of independence in study outcomes for multiple pregnancies in the same woman was taken into account using generalized estimating equations.

RESULTS

During the study period, 601,659 women had 941,496 births. Of these births, 78 births could be attributed to 50 women with JIA. Of 78 JIA pregnancies, 53 (68%) were delivered by either Caesarean section (n = 40, 51%) or instrumental delivery (n = 13, 17%); compared with other women, those with JIA had significantly higher rates of pre-eclampsia, postpartum haemorrhage and severe maternal morbidity. Compared with other infants, those with mothers with JIA were more likely to be born prematurely, but were not at increased risk of being small for gestational age, requiring neonatal intensive care, having a low Apgar score at 5 min or severe neonatal morbidity.

CONCLUSION

Infants of women with JIA did not have an increased risk of adverse neonatal outcomes. Intensive obstetric care might be required during pregnancy for women with JIA given the increased risk of maternal morbidity.

Enthesitis-related arthritis is associated with higher pain intensity and poorer health status in comparison with other categories of juvenile idiopathic arthritis: the Childhood Arthritis and Rheumatology Research Alliance Registry

OBJECTIVE

To assess the relative effect of clinical factors and medications on pain intensity, physical function, and health status in juvenile idiopathic arthritis (JIA).

METHODS

We conducted a retrospective cross-sectional study of data from children with JIA enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry. We tested whether clinical characteristics of JIA were associated with pain intensity, physical function, and health status using multivariable linear and ordinal logistic regression.

RESULTS

During the study period, 2571 subjects with JIA enrolled in the CARRA Registry. Ratings of pain intensity, physical function, and health status differed significantly between JIA categories. In comparison to other categories of JIA, subjects with enthesitis-related arthritis (ERA) reported worse pain and function. In multivariable analyses, higher active joint count and current use of nonsteroidal antiinflammatory drugs (NSAID), biologics, or corticosteroids were associated with worse scores on all patient-reported measures. ERA and older age were significantly associated with higher pain intensity and poorer health status. Systemic JIA and uveitis were significantly associated with worse health status. Enthesitis, sacroiliac tenderness, and NSAID use were independently associated with increased pain intensity in ERA. The correlation was low between physician global assessment of disease activity and patient-reported pain intensity, physical function, and health status.

CONCLUSION

Significant differences in pain intensity, physical function, and health status exist among JIA categories. These results suggest that current treatments may not be equally effective for particular disease characteristics more common in specific JIA categories, such as enthesitis or sacroiliac tenderness in ERA.
