Survey of adolescents' needs and parents' views on sexual health in juvenile idiopathic arthritis.

BACKGROUND: Although the advent of new therapeutics for juvenile idiopathic arthritis (JIA) patients has considerably lessened the impact of the disease and reduced its sequelae, the outcomes of JIA remain important in their lives. Disease repercussions and side effects of treatments may affect sexual health and cause psychological distress. This aim of the study was to determine the expectations of adolescent JIA patients and the perceptions of their parents regarding knowledge and communication with healthcare providers (HCPs) in the field of sexual health (SH). METHODS: In France, from September 2021 to April 2022, a survey was conducted, using anonymous self-administered questionnaires, among JIA patients (adults (aged 18-45 years) to provide insights from their recollection of their adolescence) and their parents in nine rheumatology centers and three patient associations. RESULTS: The responses to the 76 patient questionnaires and 43 parent questionnaires that were collected were analyzed. Half of the patients thought JIA impacted their romantic relationships, but the results were less clear-cut for their sexual activity; and 58.7% of the patients said they would be comfortable discussing the subject with HCPs, but only 26.3% had done so, mainly regarding biomedical issues. The patients and their parents thought that ideally, the topic should be addressed in an individual patient education session at the hospital (51.3% and 34.9%, respectively), in a regular consultation (47.4% and 53.5%), or in a dedicated consultation requested by the adolescent without the adolescent's parents being informed (38.2% and 20.9%). Most of the respondents thought HCPs should be proactive in SH (77.6% of the patients and 69.8% of their parents). More patients than parents said the following digital information tools must be used: videos (29.0% vs. 9.3%, p = 0.0127) and smartphone applications (25.0% vs. 9.3%, p = 0.0372). CONCLUSION: HCPs should consider addressing the unmet need for SH discussions during their patient encounters. To meet this need, we propose concrete actions in line with the wishes of patients and parents. CLINICAL TRIAL REGISTRATION NUMBER: NCT04791189.

Individual and environmental determinants associated with longer times to access pediatric rheumatology centers for patients with juvenile idiopathic arthritis, a JIR cohort study.

BACKGROUND: Despite guidelines, poor access to appropriate care for juvenile idiopathic arthritis (JIA) patients remains a global issue. Prompt referral to a pediatric rheumatology (PR) center and effective care is known to be critical for changing the natural history of the disease and improving long-term prognosis. This project assesses socio-economic factors of delayed referral to a pediatric rheumatologist (PRst) for JIA patients in France and Switzerland within the Juvenile Inflammatory Rheumatism (JIR) Cohort. METHODS: All patients diagnosed with JIA, presenting at one center of the JIRcohort in France or Switzerland with additional data on referral pathway were included. Patient characteristics at first visit to the PR center, dates of visits to healthcare providers during referral, and parent characteristics were extracted from the JIRcohort database. RESULTS: Two hundred fifty children were included. The overall median time to first PR assessment was 2.4 months [1.3; 6.9] and ranged widely across the JIA subtypes, from 1.4 months [0.6; 3.8] for children with systemic juvenile idiopathic arthritis (sJIA) to 5.3 months [2.0; 19.1] for children with enthesitis-related arthritis (ERA). A diagnosis of ERA and an appointment with an orthopedist during the referral pathway were significantly associated with a longer time before the first PR visit (hazard ratio HR 0.50 [95% CI: 0.29; 0.84]) and HR 0.68 [95% CI: 0.49; 0.93], respectively) in multivariable analysis. Having a mother with a post-graduate educational attainment level was tendentially associated with a shorter time before the first PR visit, (HR 1.32 [95% CI: 0.99; 1.78]). CONCLUSIONS: Time to first PRst visit was most often short compared to other studies and close to the British recommendations. However, this time remained too long for many patients. We observed no social inequities in access to a PRst, but we show the need to improve effective pathway and access to a PR center for JIA patients.

Is an association of acro-osteolysis, bone fragility, and enchondromatosis a newfound disease caused by an amplification of PTHLH? A case report.

BACKGROUND: Acro-osteolysis (AO) refers to resorption of the distal finger and toe phalanges. It displays two patterns: (i) diffuse AO and (ii) transverse or bandlike AO. AO can be a sign of local distress (e.g. of toxic origin), but is very often a sign of a constitutional or systemic acquired disorder. CASE PRESENTATION: A 15-year-old girl was referred to a paediatric rheumatologist for recurrent pain in her fingertips. She presented a particular cross-sectional AO associated with the presence of intraosseous cysts and bone fragility with atypical fractures. Initial laboratory tests and radiological examination did not allow an etiological diagnosis. Genetic studies revealed a 12p11.22-p11.23 microduplication of 900 kb including the PTHLH (parathyroid hormone-like hormone) gene, which encodes for a hormone involved in the regulation of endochondral ossification and differentiation of chondrocytes, via its PTHLH receptor. CONCLUSIONS: To date, 12p11.22-p11.23 duplications have been reported in five families with skeletal abnormalities, and in particular AO and enchondromatosis associated with bone fragility. This new observation, added to the other reported cases, suggests a close relationship between the presence of this microduplication and the skeletal abnormalities found in the patient. We suggest the descriptive name ABES (acro-osteolysis, bone fragility and enchondromatosis syndrome) to designate this disorder.

Access to paediatric rheumatology care in juvenile idiopathic arthritis: what do we know? A systematic review.

OBJECTIVE: This review examines time to access appropriate care for JIA patients and analyses the referral pathway before the first paediatric rheumatology (PR) visit. We also describe factors associated with a longer referral. METHODS: We performed a systematic literature review, screening electronic databases (PubMed, Web of Science, EMBASE, Cochrane library and Open Grey database) up to February 2020. Articles written before 1994 (i.e. before the introduction of the unifying term JIA) were excluded. RESULTS: From 595 nonduplicate citations found, 15 articles were finally included in the review. Most of the studies took place in Europe. The median time to first PR visit ranged from 3 to 10 months, with some disparities between referral pathway and patient characteristics. Patients with systemic-onset JIA had the shortest time to referral. Some clinical and biological factors such as swelling, fever, and elevated CRP and/or ESR were associated with a shorter time to first PR visit. Conversely, enthesitis, older age at symptom onset or pain were associated with a longer time. Whatever the country or world region, and despite disparities in healthcare system organization and healthcare practitioner availabilities, times to access PR were not wide-ranging. CONCLUSION: This is the first systematic review to summarize research on access to PR for JIA patients. The pathway of care for JIA patients remains complex, and reasons for delayed referral depend on several factors. Standardized clinical guidelines and fast-track pathways to facilitate prompt referral to specialized teams have to allow for worldwide disparities in healthcare provision.

Impaired Muscular Fat Metabolism in Juvenile Idiopathic Arthritis in Inactive Disease.

Objectives: The objective of this study was to evaluate muscular metabolic function in children with inactive juvenile idiopathic arthritis (JIA). Methods: Fifteen children with inactive JIA and fifteen healthy controls were matched by sex, biological age, and Tanner stage. Participants completed a submaximal incremental exercise test to determine their fat and carbohydrate oxidation rates. Results: Between the two groups, heart rate values and carbohydrate oxidation rates were the same, regardless of the relative intensity of exercise. Lipid oxidation rates were lower in JIA patients, regardless of the percentage of VO2 peak (p < 0.05). Respiratory exchange ratios beyond 50% of VO2 peak were higher in patients with JIA (p < 0.05). Respective maximal fat oxidation rates (MFO) for controls and children with JIA were 218.7 ± 92.2 vs. 157.5 ± 65.9 mg ⋅ min-1 (p = 0.03) and 4.9 ± 1.9 vs. 3.4 ± 1.2 mg ⋅ min-1 ⋅ kg-1 (p = 0.04). There was no difference between the two groups in heart rate, percentage of VO2 peak, or power of exercise to achieve MFO. Controls reached their MFO at an exercise power significantly higher than did JIA subjects (42.8 ± 16.8 and 31.9 ± 9.8 W, p = 0.004). Conclusion: Children with JIA show metabolic disturbance during exercise, even when the disease is considered inactive. This disturbance is seen in a lower lipid oxidation rate during submaximal exercise.

Medical pathways of children with juvenile idiopathic arthritis before referral to pediatric rheumatology centers.

OBJECTIVE: A better understanding about the referral pathway of patients suffering from juvenile idiopathic arthritis (JIA) is required The aim of this study was to describe and analyze time from onset of symptoms to first pediatric rheumatology (PR) visit and the referral pathway of children with incident JIA in two French competence centers. METHODS: From October 2009 to October 2017, new JIA patients were registered in the "Auvergne-Loire cohort on JIA". We collected referral pathway, symptom onset, biological and clinical data at first assessment in PR department. RESULTS: In all, 111 children were included. Median time to first PR visit was 3.3 months [interquartile range (IQR) 1.3, 10.7] with a significant difference between JIA subtypes. After exclusion of systemic JIA, older age at onset of symptoms, and presence of enthesitis or joint pain were significantly associated with a longer time to first PR visit, while joint swelling or limping, abnormal ESR or CRP were associated with a shorter time. The median number of health care practitioners met was 3 [IQR 3, 4]. Orthopedists referred children to a PR center in 64% of cases, pediatricians in 50%, emergency care practitioners in 27% and general practitioners in 25%. Although non-systemic JIAs are not an emergency, 45% were referred to the emergency room. CONCLUSION: Time to first PR visit is rather short compared to other countries but remains too long. Pediatric rheumatologists should offer primary care providers basic training on JIA and fast direct access to PR departments if JIA is suspected.

Safety of biological agents in paediatric rheumatic diseases: A real-life multicenter retrospective study using the JIRcohorte database.

OBJECTIVE: To analyse and report the incidence of side effects of biological agents in paediatric patients with inflammatory diseases using of real-life follow-up cohort. METHODS: In this international, observational, retrospective, multicentre study of children treated by biological agents and followed in the Juvenile Inflammatory Rheumatism (JIR) cohort (JIRcohorte) network, a Kaplan-Meier method was used to estimate the occurrence of adverse events. A Cox model was constructed to identify independent predictors of adverse events. RESULTS: Overall 813 patients totalling 3439 patients-year (PY) of biological agents were included. The main diagnosis was juvenile idiopathic arthritis (84%). A total of 222 patients (27.3%) had 419 adverse events, representing an incidence rate of 12.2 per 100 PY 95% CI [11.0; 13.4]. The overall incidence rate of serious adverse events was 3.9 per 100 PY 95% CI [3.2; 4.6]. Tocilizumab and infliximab were significantly associated with adverse events and canakinumab with serious adverse events. Univariate and multivariable analysis of adverse events and serious adverse events indicated that patients under biological agents with concomitant immunosuppressive drugs (excluding methotrexate) suffered from more of these events. CONCLUSION: This study suggests an overall an acceptable safety of biologic agents in children with inflammatory rheumatic diseases treated with biological agents. However, the concomitant prescription of immunosuppressive drugs with biological agents represents a substantial risk of adverse events.

MISS questionnaire in French version: a good tool for children and parents to assess methotrexate intolerance.

The aim of this study was to assess the relevance for children and parents to use the French-validated version of the methotrexate intolerance severity score (MISS), a measure of methotrexate intolerance for children suffering from juvenile idiopathic arthritis. The French-version MISS was developed following the "Guidelines for the process of cross-cultural adaptation of self-report measures." The new version was tested in families of children with juvenile idiopathic arthritis who completed the questionnaire twice at a 2-week interval. Item correlations, Cronbach's alpha, and kappa coefficients were computed to evaluate acceptability, internal consistency, and reproducibility. A culturally acceptable version to French was obtained. A total of 71 individuals were included from May 2015 to November 2015. The results show very good acceptability: good response rate (80%), few missing data (<1%) and good understanding of parents and children. The inter-item, dimension-item, and inter-dimension correlations were satisfactory (except for "vomiting" items-other items correlation). Cronbach's alpha coefficient was well higher than the usually recommended value of 0.6. The results of validity of internal and external consistencies were satisfactory. We also found good agreement between the test-retest for every family. The empirical discriminative cut-off point of 3 showed a sensitivity of 86% and a specificity of 83%. The MISS questionnaire is quick to complete, easy to use. It can be completed by children or their parents with no significant difference. This validated French-version MISS can help study prevalence and risk factors of methotrexate intolerance, better detect this intolerance, and provide better support for patients on long-term treatment.

Why we need a process on breaking news of Juvenile Idiopathic Arthritis: a mixed methods study.

BACKGROUND: Juvenile Idiopathic Arthritis is the most common chronic pediatric rheumatic disease. The announcement of Juvenile Idiopathic Arthritis poses for parents a number of challenges that make it hard to accept a diagnosis of the disease for their child; yet to our knowledge, no study to date has focused on the time period immediately surrounding the diagnosis. This study sets out to describe parents' experiences in engaging with their child's diagnosis of Juvenile Idiopathic Arthritis. METHODS: This is a mixed methods study. Semi-structured interviews of families with a Juvenile Idiopathic Arthritis child were conducted. A grounded-theory thematic analysis was performed. Items that emerged in the interviews were compiled into a self-administered questionnaire. RESULTS: Eleven families participated in the qualitative study. Sixty families responded to the questionnaire. The path of parents was characterized by doubt (before, during and after diagnosis) while the disease tended to take center stage. Doubt was generated through mismatches in perspectives between the parents' circle of acquaintances, physicians, and the parents' own subjective experiences of symptoms. This study also found that social support and parent associations occupied an ambiguous position between help and stigmatization. CONCLUSIONS: Doubt fuels self-energizing spirals that take root as parents learn the news that their child has Juvenile Idiopathic Arthritis. These spirals of doubt may influence parents' experiences at every stage throughout the course of disease. Our data support the implementation of a specific process dedicated to breaking the news of Juvenile Idiopathic Arthritis to parents.
