Sleep in children and adolescents with juvenile idiopathic arthritis: a systematic review and meta-analysis of case-control studies

EULAR points to consider for patient education in physical activity and self-management of pain during transitional care

OBJECTIVES

A EULAR task force was convened to develop points to consider (PtC) for patient education in physical activity and self-management of pain in young people with juvenile-onset rheumatic and musculoskeletal diseases during transitional care.

METHODS

A task force of 26 people from 10 European countries followed the EULAR Standardised Operating Procedures to establish overarching principles (OAPs) and PtC based on a literature review and expert consensus. Level of evidence (LoE), grade of recommendation (GoR) and level of agreement (LoA) were determined.

RESULTS

Two OAPs and seven PtC were formulated. The OAPs highlight the importance of personalised transitional care in rheumatology, ideally based on shared decision-making and incorporate interactive education to empower young individuals in managing their physical activity and pain. The PtC emphasise the clinical importance of patient education in these areas to improve readiness to transfer from paediatric to adult care. For two PtC, the GoR was moderate (grade B), based on individual cohort study (LoE 2b). For the remaining five PtC, the GoR was weak (grade D), based on expert opinion (LoE 5). The LoA among the task force was high, ranging from 9.4 to 9.8, except for one PtC that was 8.7.

CONCLUSION

These EULAR PtC establish guidance on best practices for delivering patient education in physical activity and self-management of pain during transitional care in rheumatology. The adoption of these PtC in clinical settings is recommended to standardise and optimise transitional care across European healthcare systems. Additionally, the task force expects that these PtC will drive future research and potentially shape policies across Europe.

Physical (in)activity and screen-based media use of adolescents with juvenile idiopathic arthritis over time - data from a German inception cohort

BACKGROUND

Regular physical activity (PA) has been proven to help prevent non-communicable diseases and is beneficial for disease management in chronically ill populations. Physical inactivity and recreational screen-based media (SBM) use are related to poor health outcomes and common among youth. This study aimed to (1) investigate PA levels and recreational SBM use of adolescents with JIA over time and (2) compare these behaviours with those of their peers.

METHODS

Data from JIA patients and their peers enrolled in the inception cohort study ICON at 11 German centers were analyzed. Individuals aged 13 and over were followed prospectively with questionnaires concerning PA level, recreational SBM use, and health-related quality of life (HRQoL) at a two-year interval. Group by time interactions were analyzed using linear mixed models.

RESULTS

Data of 214 patients (mean age at first documentation 14.4 ± 0.9 years, female 63%) and 141 peers could be considered. At first documentation, patients were less physically active compared to their peers (p < 0.001). In contrast to their peers, patients' PA levels increased over time (OR 3.69; 95% CI: 1.01-13.50, p = 0.048). Mean screen time did not differ significantly between patients and peers (first documentation: 3.5 h vs. 3.0 h, p = 0.556; follow-up: 3.6 h vs. 3.3 h, p = 0. 969). During the observation period, male patients reported higher PA levels than female patients, but also higher screen time levels. While low socioeconomic status (SES) (OR 14.40; 95%-CI: 2.84-73.15) and higher cJADAS-10 score (OR 1.31; 95%-CI: 1.03-1.66) increased the likelihood for high SBM use (≥ 4.5 h/d), higher PedsQL psychosocial health score (OR 0.93; 95%-CI: 0.88-0.99) was associated with a decreased likelihood.

CONCLUSIONS

Adolescents with JIA become more physically active over the disease course and achieve comparable levels of PA and recreational screen time to their peers. However, the vast majority appear to be insufficiently physically active. Future interventions to promote healthy lifestyles should include gender and SES as important determinants to reach most vulnerable groups.

Sleep Disorders and Chronic Pain Syndromes in the Pediatric Population

Sleep problems are widespread in children and adolescents suffering from chronic pain disorders. Sleep loss intensifies the experience of pain and is detrimental to the budding self-efficacy of a young individual with limitless horizons. Addressing sleep disorders may prevent the chronification of pain and prevent adverse health outcomes, such as functional impairment, psychiatric comorbidities and overall poor quality of life. This review will explore the cyclical nature between sleep, pain and mood, as well as the functional impact of this relationship on children and adolescents. There will be a discussion about sleep assessment and diagnostic testing, followed by a description of sleep disturbances found in specific pain conditions, ranging from headache, musculoskeletal/abdominal pain, to rheumatologic disorders. Finally, there will be a brief review of pharmacologic and behavioral interventions designed to improve sleep quality, and when possible, to alleviate pain.

Persistent neuroinflammation of the right insular cortex in children with juvenile idiopathic arthritis: a proton MRS study

OBJECTIVE

The aim of this study of children with juvenile idiopathic arthritis (JIA) was to use proton magnetic resonance spectroscopy (1H-MRS) to compare the levels of five neurometabolites in the right and left insular cortexes of subjects in three groups: JIA-active, JIA-inactive, and healthy controls (HCs).

METHODS

Two inflammation markers and five psychometric scores were determined. 1H-MRS was used to measure the levels of total N-acetylaspartate (NAA), total choline (Cho), myo-inositol (mI), and glutamate (Glu), and the complex of glutamine and glutamate (Glx) relative to total creatine (tCr) in the right and left insular cortexes of participants.

RESULTS

Intra-group comparisons indicated that each group had higher levels of NAA/tCr, Glu/tCr, Glx/tCr, and mI/tCr in the right insula, and higher levels of Cho/tCr in the left insula. Inter-group comparisons of the right insula indicated that the JIA-active and JIA-inactive groups had higher levels of Cho/tCr than the HC group, but none of the other inter-group differences were statistically significant. The score of the Sleep Disturbance Scale for Children (SDCD) had an inverse correlation with the level of Cho/tCr in the right insular cortex of patients in the JIA-inactive group.

CONCLUSIONS

Relative to the HC group, the right insular cortex of subjects in the JIA-active and the JIA-inactive groups had greater levels of Cho/tCr, suggesting increased inflammation in this region. The Cho/tCr level in the right insular cortex had an inverse correlation with SDCD score in the JIA-inactive group. Key Points • Healthy controls and JIA patients had higher levels of tNAA/tCr, Glu/tCr, Glx/tCr, and mI/tCr in the right insula, and higher levels of Cho/tCr in the left insula. • A greater level of Cho/tCr in the right insula of JIA-active and JIA-inactive patients indicated neuroinflammation in this region. • The Cho/tCr level in the right insular cortex had an inverse correlation with SDCD score in the JIA-inactive group.

Physical activity as a promising alternative for young people with juvenile idiopathic arthritis: Towards an evidence-based prescription

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in young people. Although biologics now enable most children and adolescents with JIA to enjoy clinical remission, patients present lower physical activity and spend more time in sedentary behavior than their healthy counterparts. This impairment probably results from a physical deconditioning spiral initiated by joint pain, sustained by apprehension on the part of both the child and the child's parents, and entrenched by lowered physical capacities. This in turn may exacerbate disease activity and lead to unfavorable health outcomes including increased risks of metabolic and mental comorbidities. Over the past few decades, there has been growing interest in the health benefits of increased overall physical activity as well as exercise interventions in young people with JIA. However, we are still far from evidence-based physical activity and / or exercise prescription for this population. In this review, we give an overview of the available data supporting physical activity and / or exercise as a behavioral, non-pharmacological alternative to attenuate inflammation while also improving metabolism, disease symptoms, poor sleep, synchronization of circadian rhythms, mental health, and quality of life in JIA. Finally, we discuss clinical implications, identify gaps in knowledge, and outline a future research agenda.
