OBJECTIVES:Adolescents with juvenile fibromyalgia (JFM) are typically sedentary despite recommendations for physical exercise, a key component of pain management. Interventions such as ...cognitive-behavior therapy (CBT) are beneficial but do not improve exercise participation. The objective of this study was to obtain preliminary information about the feasibility, safety, and acceptability of a new intervention—Fibromyalgia Integrative Training for Teens (FIT Teens), which combines CBT with specialized neuromuscular exercise training modified from evidence-based injury prevention protocols.
MATERIALS AND METHODS:Participants were 17 adolescent females (aged 12 to 18 y) with JFM. Of these, 11 completed the 8-week (16 sessions) FIT Teens program in a small-group format with 3 to 4 patients per group. Patients provided detailed qualitative feedback via individual semistructured interviews after treatment. Interview content was coded using thematic analysis. Interventionist feedback about treatment implementation was also obtained.
RESULTS:The intervention was found to be feasible, well tolerated, and safe for JFM patients. Barriers to enrollment (50% of those approached) included difficulties with transportation or time conflicts. Treatment completers enjoyed the group format and reported increased self-efficacy, strength, and motivation to exercise. Participants also reported decreased pain and increased energy levels. Feedback from participants and interventionists was incorporated into a final treatment manual to be used in a future trial.
DISCUSSION:Results of this study provided initial support for the new FIT Teens program. An integrative strategy of combining pain coping skills via CBT enhanced with tailored exercise specifically designed to improve confidence in movement and improving activity participation holds promise in the management of JFM.
To describe protocol adaptations to the Fibromyalgia Integrative Training for Teens (FIT Teens) randomized controlled trial in response to the COVID-19 pandemic. The overarching aims of the FIT Teens ...multi-site 3-arm comparative effectiveness trial are to assess whether a specialized neuromuscular exercise training intervention combined with cognitive-behavioral therapy (CBT) is superior to CBT alone or graded aerobic exercise alone.
The trial was originally designed as an in-person, group-based treatment with assessments at baseline, mid- and post-treatment, and four follow-up time points. The original study design and methodology was maintained with specific modifications to screening, consenting, assessments, and group-based treatments to be delivered in remote (telehealth) format in response to COVID-19 restrictions.
Study enrollment was paused in March 2020 for five months to revise operations manuals, pilot remote treatment sessions for accuracy and fidelity, complete programming of REDCap assent/consent and assessment materials, train study staff for new procedures and obtain regulatory approvals. The trial was relaunched and has been successfully implemented in remote format since July 2020. Trial metrics thus far demonstrate a consistent rate of enrollment, strong attendance at remote treatment sessions, high retention rates and high treatment fidelity after protocol adaptations were implemented.
Preliminary findings indicate that FIT Teens protocol adaptations from in-person to remote are feasible and allowed for sustained enrollment, retention, and treatment fidelity comparable to the in-person format. Methodologic and statistical considerations resulting from the adaptations are discussed as well as implications for interpretation of results upon completion of the trial.

Objective
Cognitive–behavioral therapy (CBT) is effective in reducing disability among youth with juvenile fibromyalgia (FM); however, engagement in moderate to vigorous physical activity remains ...poor, even after CBT. The purpose of this study was to evaluate the feasibility and preliminary outcomes of an innovative program combining CBT with specialized neuromuscular exercise: the Fibromyalgia Integrative Training for Teens (FIT Teens) program.
Methods
Adolescents with juvenile FM (n = 22, all female, ages 12–18 years) from 2 urban children's hospitals participated in the 8‐week FIT Teens intervention. Participants completed measures of pain intensity, functional disability, depressive symptoms, pain catastrophizing, fear of movement, and readiness to change at baseline and after the intervention.
Results
The feasibility of the intervention across 2 sites was documented, including high retention rates (80%). Participants showed significant decreases in functional disability (P < 0.05), depression (P < 0.001), fear of movement (P < 0.01), and pain catastrophizing (P < 0.001) from pre‐ to postintervention. Results of the readiness to change measure indicated a significant decrease in precontemplation (P < 0.01) and increase in action/maintenance scores (P < 0.001). All results demonstrated medium to large effect sizes.
Conclusion
Adolescents with juvenile FM reported significant improvements in physical function and reduced fear of movement following the intervention. Improvement in physical function was achieved in a shorter time frame than in a prior trial of CBT without an exercise component. Further work is needed to compare the FIT Teens program with existing approaches and determine whether objective changes in exercise participation are achieved.
Objective
To determine the frequency, time to flare, and predictors of disease flare upon withdrawal of anti–tumor necrosis factor (anti‐TNF) therapy in children with polyarticular forms of juvenile ...idiopathic arthritis (JIA) who demonstrated ≥6 months of continuous clinically inactive disease.
Methods
In 16 centers 137 patients with clinically inactive JIA who were receiving anti‐TNF therapy (42% of whom were also receiving methotrexate MTX) were prospectively followed up. If the disease remained clinically inactive for the initial 6 months of the study, anti‐TNF was stopped and patients were assessed for flare at 1, 2, 3, 4, 6, and 8 months. Life‐table analysis, t‐tests, chi‐square test, and Cox regression analysis were used to identify independent variables that could significantly predict flare by 8 months or time to flare.
Results
Of 137 patients, 106 (77%) maintained clinically inactive disease while receiving anti‐TNF therapy for the initial 6 months and were included in the phase of the study in which anti‐TNF therapy was stopped. Stopping anti‐TNF resulted in disease flare in 39 (37%) of 106 patients by 8 months. The mean/median ± SEM time to flare was 212/250 ± 9.77 days. Patients with shorter disease duration at enrollment, older age at onset and diagnosis, shorter disease duration prior to experiencing clinically inactive disease, and shorter time from onset of clinically inactive disease to enrollment were found to have significantly lower hazard ratios for likelihood of flare by 8 months (P < 0.05).
Conclusion
Over one‐third of patients with polyarticular JIA with sustained clinically inactive disease will experience a flare by 8 months after discontinuation of anti‐TNF therapy. Several predictors of lower likelihood of flare were identified.
Chronic pain in children is associated with significant negative impact on social, emotional, and school functioning. Previous studies on the impact of pain on children’s functioning have primarily ...used mixed samples of pain conditions or single pain conditions (eg, headache and abdominal pain) with relatively small sample sizes. As a result, the similarities and differences in the impact of pain in subgroups of children with chronic pain have not been closely examined.
OBJECTIVE:To compare pain characteristics, quality of life, and emotional functioning among youth with pediatric chronic migraine (CM) and juvenile fibromyalgia (JFM).
METHODS:We combined data obtained during screening of patients for 2 relatively large intervention studies of youth (age range, 10 to 18 y) with CM (N=153) and JFM (N=151). Measures of pain intensity, quality of life (Pediatric Quality of Life; PedsQL, child and parent-proxy), depressive symptoms (Children’s Depression Inventory), and anxiety symptoms (Adolescent Symptom Inventory-4—Anxiety subscale) were completed by youth and their parent. A multivariate analysis of covariance controlling for effects of age and sex was performed to examine differences in quality of life and emotional functioning between the CM and JFM groups.
RESULTS:Youth with JFM had significantly higher anxiety and depressive symptoms, and lower quality of life in all domains. Among children with CM, overall functioning was higher but school functioning was a specific area of concern.
DISCUSSION:Results indicate important differences in subgroups of pediatric pain patients and point to the need for more intensive multidisciplinary intervention for JFM patients.
Objectives. Currently, there are no prospective studies exploring the prognosis of patients with juvenile primary FM syndrome (JPFS) or their physical, emotional and social outcomes as they enter the ...early adult years. The primary objective of this study was to assess long-term outcomes of a paediatric sample of clinically referred JPFS patients and their matched healthy controls. Methods. Participants were 48 youths (current mean age = 19 years) diagnosed with JPFS in childhood or adolescence and 43 healthy controls matched in age, gender and race. The average length of follow-up was 3.67 years (range 2–6 years). Participants completed online (web-based) self-report questionnaires about current pain and physical symptoms, health status, anxiety, depressive symptoms and current and past treatments. Results. Results showed that 62.5% of participants in the JPFS group continued to experience widespread pain and 60.4% reported having all the cardinal features of FM syndrome (including widespread pain, poor sleep and fatigue) at follow-up. The JPFS group reported significantly lower scores on all measures of health status and physical functioning compared with healthy controls and significantly greater symptoms of anxiety and depression. Conclusion. The results of this controlled follow-up study demonstrate that symptoms of FM appear to be chronic in a majority of clinically referred JPFS patients and the associated physical and emotional impairment can also be persistent. Implications for treatment and the need for further prospective longitudinal studies are discussed.
Objective
Little is known about the impact of family environment on the long‐term adjustment of patients with juvenile‐onset fibromyalgia (JFM). Our objective was to evaluate whether family ...environment in early adolescence predicted later physical functioning and depressive symptoms of adolescents with JFM as they transitioned to early adulthood in the context of a controlled long‐term followup study.
Methods
Participants consisted of 39 youth (mean age 18.7 years) with JFM and 38 healthy matched controls who completed web‐based surveys about their health status (Short Form 36 health survey) and depressive symptoms (Beck Depression Inventory II) ∼4 years after a home‐based, in‐person assessment of child and family functioning. During the initial assessment, parents of the participants (94% mothers) completed the Family Environment Scale and adolescents (mean age 14.8 years) completed self‐report questionnaires about pain (visual analog scale) and depressive symptoms (Children's Depression Inventory).
Results
The results indicated that family environment during early adolescence significantly predicted greater depressive symptoms in early adulthood for both the JFM group and the healthy controls. In particular, a controlling family environment (use of rules to control the family and allowing little independence) during early adolescence was the driving factor in predicting poorer long‐term emotional functioning for patients with JFM. Family environment did not significantly predict longer‐term physical impairment for either group.
Conclusion
Adolescents with JFM from controlling family environments are at an increased risk for poorer emotional functioning in early adulthood. Behavioral and family interventions should foster independent coping among adolescents with JFM and greater parenting flexibility to enhance successful long‐term coping.
To determine the frequency of laboratory abnormalities with methotrexate (MTX) use in patients with juvenile idiopathic arthritis (JIA); to identify potential risk factors for MTX toxicity requiring ...medical interventions; and to compare the frequency of liver function abnormalities in patients treated with MTX to those not treated with MTX.
Results of MTX surveillance laboratory testing (SLT) available in clinical databases were reviewed for 588 children with JIA. Information on demographics, JIA features, and factors previously associated with increased frequency of SLT abnormalities was obtained.
Results of SLT performed in at least 4-month intervals were available for 138 JIA patients whose JIA was not treated with MTX, and for 198 JIA patients treated with MTX plus folic acid. On SLT of the MTX-treated patients, there were 44 of 2650 (1.7%) AST tests and 90 of 2647 (3.4%) ALT tests that exceeded 2 times the upper limit of normal (> 2 ULN) in 30 children (15%). AST or ALT tests at > 2 ULN occurred more often with systemic JIA (p = 0.04), macrophage activation syndrome, during infections, in systemic antibiotic use, and after intensifying JIA drug regimens. AST or ALT results at > 2 ULN were as frequent among MTX-treated children as those not treated with MTX. Renal and hematological abnormalities with MTX were uncommon.
Liver enzyme abnormalities > 2 ULN are rare in JIA, irrespective of MTX exposure. These data suggest that the adult standard of SLT every 4-8 weeks may not be necessary in children treated with MTX, especially if certain risk factors are absent.
Objective To describe school absences in adolescents with Juvenile Primary Fibromyalgia Syndrome (JPFS) and examine the relationship between school absenteeism, pain, psychiatric symptoms, and ...maternal pain history. Methods Adolescents with JPFS (N = 102; mean age 14.96 years) completed measures of pain and depressive symptoms, and completed a psychiatric interview. Parents provided information about the adolescents’ school absences, type of schooling, and parental pain history. School attendance reports were obtained directly from schools. Results Over 12% of adolescents with JPFS were homeschooled. Those enrolled in regular school missed 2.9 days per month on average, with one-third of participants missing more than 3 days per month. Pain and maternal pain history were not related to school absenteeism. However, depressive symptoms were significantly associated with school absences. Conclusion Many adolescents with JPFS experience difficulties with regular school attendance. Long-term risks associated with school absenteeism and the importance of addressing psychological factors are discussed.
Juvenile Fibromyalgia (JFM) is characterized by chronic widespread musculoskeletal pain and approximately 40% of children and adolescents with JFM also suffer from benign joint hypermobility (HM). It ...is not currently known if the presence of HM affects the pain experience of adolescents with JFM. The objective of this study was to examine whether there were any differences in self-reported pain intensity and physiologic pain sensitivity between JFM patients with and without joint HM.
One hundred thirty-one adolescent patients with JFM recruited from four pediatric rheumatology clinics completed a daily visual analogue scale (VAS) pain rating for one week and underwent a standardized 18-count tender point (TP) dolorimeter assessment. Medical records were reviewed for the presence of joint HM. Average pain VAS ratings, tender point count and tender point sensitivity were compared between JFM patients with and without hypermobility (HM+ and HM-).
Nearly half (48%) the sample of JFM patients were found to be HM+. HM+ and HM- patients did not differ in their self-reported pain intensity. However, HM + patients had significantly greater pain sensitivity, with lower TP thresholds (p = 0.002) and a greater number of painful TPs (p = 0.003) compared to HM- patients.
The presence of HM among adolescent patients with JFM appears to be associated with enhanced physiologic pain sensitivity, but not self-report of clinical pain. Further examination of the mechanisms for increased pain sensitivity associated with HM, especially in adolescents with widespread pain conditions such as JFM is warranted.
