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

Transition to Adult Care in Autoinflammatory Diseases: A Cohort of 111 French Patients

BACKGROUND

Transitioning from pediatric to adult care is a critical step for individuals with autoinflammatory diseases, requiring effective programs to ensure continuity of care and disease management. Despite various recommendations, the effectiveness of transition programs, particularly in monogenic autoinflammatory diseases, remains understudied.

METHODS

A single-center medical records review study was conducted at the French National Reference Center for Adult Autoinflammatory Diseases in Tenon Hospital from 2017 to 2023. All patients who had consulted for the first time between the ages of 15 and 30 years and had received care for an autoinflammatory disease during childhood were included. The patients were classified according to whether they had undergone a transition, defined as either no transition, simple transition (referral letter), or joint transition (pediatrician and adult physician consultation).

RESULTS

One hundred eleven patients (median age, 18 years) were included. Patients who consulted without transition started adult follow-up and were followed up less regularly than those who underwent the transition process (p < 0.001 and p = 0.028). In patients with familial Mediterranean fever, the absence of a formal transition was associated with poorer disease control at baseline (p = 0.019). The type of transition did not impact disease control during follow-up.

CONCLUSIONS

Participation in a transition program is associated with earlier and more regular follow-up in adulthood. Although transition type did not significantly impact disease control during follow-up in familial Mediterranean fever, the potential benefit of joint consultation extends beyond consultation frequency and disease outcomes, encompassing patient perspectives and self-management abilities. This study highlights the significance of collaborative transition programs in AIDs.

Relapses of juvenile idiopathic arthritis in adulthood: A monocentric experience

INTRODUCTION

Our aim was to describe a monocentric cohort of young adult patients with juvenile idiopathic arthritis (JIA), assessing the risk of relapse after transition to adult care.

METHODS

We conducted a retrospective study and collected clinical, serological, and demographic data of young adult patients (18-30 years old) referred to the Transition Clinic of a single Italian centre between January 2020 and March 2023. Patients with systemic-onset JIA were excluded. Primary outcome was disease relapse, defined by Wallace criteria. Risk factors were analysed by Cox proportional hazards regression.

RESULTS

Fifty patients with age 18-30 years old were enrolled in the study and followed for a median 30 months. The median disease duration at transition was 15 years. Twenty (40%) patients were on conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and 38 (76%) were on biological DMARDs through adulthood. Twenty-three patients relapsed after transitioning to adult care for a median 9-month follow-up (IQR 0-46.5). Most relapses involved the knees (69.6%). The univariate analysis identified monoarthritis (HR 4.67, CI 1.069-20.41, p value = 0.041) as the main risk factor for relapse within the first 36 months of follow-up. Early onset, ANA positivity, past and ongoing treatment with csDMARDs or bDMARDs, therapeutic withdrawal, and disease activity within 12 months before transition did not significantly influence the risk of relapse.

CONCLUSION

In JIA patients, the risk of relapse after transitioning to adult care remains high, irrespective of disease subtype and treatment. The main risk factor for the early occurrence of articular activity is monoarticular involvement.

Psychiatric Morbidity Is Common Among Children With Juvenile Idiopathic Arthritis: A National Matched Cohort Study

OBJECTIVE

Juvenile idiopathic arthritis (JIA) is a chronic rheumatic disease that causes joint inflammation and pain. Previous studies have indicated affected mental health and increased risk of psychiatric conditions among patients with JIA. We aimed to explore differences in psychiatric morbidity between children with JIA and their peers. We further studied if parental socioeconomic status (SES) influences the association between JIA and the risk of psychiatric morbidity.

METHODS

We used a matched cohort design to estimate the association between JIA and psychiatric disease. Children with JIA, born between 1995 and 2014, were identified in Danish national registers. Based on birth registers, we randomly selected 100 age- and sex-matched children per index child. Index date was the date of the fifth JIA diagnosis code or the date of matching for reference children. End of follow-up was the date of psychiatric diagnosis, death, emigration, or December 31, 2018, whatever came first. Data were analyzed using a Cox proportional hazard model.

RESULTS

We identified 2086 children with JIA with a mean age at diagnosis of 8.1 years. Children with JIA had a 17% higher instantaneous risk of a psychiatric diagnosis when compared with the reference group, with an adjusted hazard ratio of 1.17 (95% CI 1.02-1.34). Relevant associations were found only for depression and adjustment disorders. Stratifying our analysis for SES showed no modifying effect of SES.

CONCLUSION

Children with JIA had a higher risk of psychiatric diagnoses compared to their peers, especially diagnoses of depression and adjustment disorders. The association between JIA and psychiatric disease did not depend on parental SES.

A survey of Canadian adult rheumatologists' knowledge, comfort level, and barriers in assessing psychosocial needs of young adults with rheumatic diseases

To assess adult rheumatologists' comfort level, current practices, and barriers to provision of optimal care in supporting young adults with pediatric-onset rheumatic conditions in Canada. Survey questions were informed by literature review, a needs assessment, and using milestones listed by the Royal College of Physicians and Surgeons of Canada for the entrustable professional activities (EPAs) applicable to care for rheumatology patients transitioning to adult practice. The electronic survey was distributed to adult rheumatology members of the Canadian Rheumatology Association over 4 months. Four hundred and fifty-one rheumatologists received the survey, with a response rate of 15.2%. Most respondents were from Ontario and had been in practice ≥ 10 years. Three quarters reported a lack of training in transition care although the same proportion were interested in learning more about the same. Approximately 40% felt comfortable discussing psychosocial concerns such as gender identity, sexuality, contraception, drug and alcohol use, vaping, and mental health. Despite this, 45-50% reported not discussing vaping or gender identity at all. The most frequently reported barriers to providing transition care were lack of primary care providers, allied health support, and training in caring for this age group. Most adult rheumatologists lack formal training in transition care and view it as a barrier to providing care for this unique patient population. Future educational initiatives for adult rheumatology trainees should include issues pertaining to adolescents and young adults. More research is needed to assess the effectiveness of resources such as transition navigators in ensuring a successful transition process.

Juvenile idiopathic arthritis patients with positive family history of autoimmune thyroid disease might benefit from serological screening: analysis of the international Pharmachild registry

BACKGROUND

Little is known about the association between juvenile idiopathic arthritis (JIA) and autoimmune thyroid disease (AITD) and therefore there are no indications for AITD screening in this population, which is possible using standard blood tests. The objective of this study is to determine the prevalence and predictors of symptomatic AITD in JIA patients from the international Pharmachild registry.

METHODS

Occurrence of AITD was determined from adverse event forms and comorbidity reports. Associated factors and independent predictors for AITD were determined using univariable and multivariable logistic regression analyses.

RESULTS

The prevalence of AITD after a median observation period of 5.5 years was 1.1% (96/8965 patients). Patients who developed AITD were more often female (83.3% vs. 68.0%), RF positive (10.0% vs. 4.3%) and ANA positive (55.7% vs. 41.5%) than patients who did not. AITD patients were furthermore older at JIA onset (median 7.8 years vs. 5.3 years) and had more often polyarthritis (40.6% vs. 30.4%) and a family history of AITD (27.5% vs. 4.8%) compared to non-AITD patients. A family history of AITD (OR = 6.8, 95% CI: 4.1 - 11.1), female sex (OR = 2.2, 95% CI: 1.3 - 4.3), ANA positivity (OR = 2.0, 95% CI: 1.3 - 3.2) and older age at JIA onset (OR = 1.1, 95% CI: 1.1 - 1.2) were independent predictors of AITD on multivariable analysis. Based on our data, 16 female ANA positive JIA patients with a family history of AITD would have to be screened during ±5.5 years using standard blood tests to detect one case of AITD.

CONCLUSIONS

This is the first study to report independent predictor variables for symptomatic AITD in JIA. Female ANA positive JIA patients with positive family history are at increased risk of developing AITD and thus might benefit from yearly serological screening.
