Abstract
Neutrophilic inflammation is a hallmark of many monogenic autoinflammatory diseases; pathomechanisms that regulate extravasation of damaging immune cells into surrounding tissues are poorly understood. Here we identified three unrelated boys with perinatal-onset of neutrophilic cutaneous small vessel vasculitis and systemic inflammation. Two patients developed liver fibrosis in their first year of life. Next-generation sequencing identified two de novo truncating variants in the Src-family tyrosine kinase, LYN, p.Y508*, p.Q507* and a de novo missense variant, p.Y508F, that result in constitutive activation of Lyn kinase. Functional studies revealed increased expression of ICAM-1 on induced patient-derived endothelial cells (iECs) and of β2-integrins on patient neutrophils that increase neutrophil adhesion and vascular transendothelial migration (TEM). Treatment with TNF inhibition improved systemic inflammation; and liver fibrosis resolved on treatment with the Src kinase inhibitor dasatinib. Our findings reveal a critical role for Lyn kinase in modulating inflammatory signals, regulating microvascular permeability and neutrophil recruitment, and in promoting hepatic fibrosis.

Abstract
OBJECTIVE To develop recommendations for the screening, monitoring, and treatment of uveitis in children with juvenile idiopathic arthritis (JIA). METHODS Pediatric rheumatologists, ophthalmologists with expertise in uveitis, patient representatives, and methodologists generated key clinical questions to be addressed by this guideline. This was followed by a systematic literature review and rating of the available evidence according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology. A group consensus process was used to compose the final recommendations and grade their strength as conditional or strong. RESULTS Due to a lack of literature with good quality of evidence, recommendations were formulated on the basis of available evidence and a consensus expert opinion. Regular ophthalmic screening of children with JIA is recommended because of the risk of uveitis, and the frequency of screening should be based on individual risk factors. Regular ophthalmic monitoring of children with uveitis is recommended, and intervals should be based on ocular examination findings and treatment regimen. Ophthalmic monitoring recommendations were strong primarily because of concerns of vision-threatening complications of uveitis with infrequent monitoring. Topical glucocorticoids should be used as initial treatment to achieve control of inflammation. Methotrexate and the monoclonal antibody tumor necrosis factor inhibitors adalimumab and infliximab are recommended when systemic treatment is needed for the management of uveitis. The timely addition of nonbiologic and biologic drugs is recommended to maintain uveitis control in children who are at continued risk of vision loss. CONCLUSION This guideline provides direction for clinicians and patients/parents making decisions on the screening, monitoring, and management of children with JIA and uveitis, using GRADE methodology and informed by a consensus process with input from rheumatology and ophthalmology experts, current literature, and patient/parent preferences and values.

Abstract
OBJECTIVE To develop treatment recommendations for children with juvenile idiopathic arthritis manifesting as non-systemic polyarthritis, sacroiliitis, or enthesitis. METHODS The Patient/Population, Intervention, Comparison, and Outcomes (PICO) questions were developed and refined by members of the guideline development teams. A systematic review was conducted to compile evidence for the benefits and harms associated with treatments for these conditions. GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology was used to rate the quality of evidence. A group consensus process was conducted among the Voting Panel to generate the final recommendations and grade their strength. A Parent and Patient Panel used a similar consensus approach to provide patient/caregiver preferences for key questions. RESULTS Thirty-nine recommendations were developed (8 strong and 31 conditional). The quality of supporting evidence was very low or low for 90% of the recommendations. Recommendations are provided for the use of nonsteroidal antiinflammatory drugs, disease-modifying antirheumatic drugs, biologics, and intraarticular and oral glucocorticoids. Recommendations for the use of physical and occupational therapy are also provided. Specific recommendations for polyarthritis address general medication use, initial and subsequent treatment, and adjunctive therapies. Good disease control, with therapeutic escalation to achieve low disease activity, was recommended. The sacroiliitis and enthesitis recommendations primarily address initial therapy and adjunctive therapies. CONCLUSION This guideline provides direction for clinicians, caregivers, and patients making treatment decisions. Clinicians, caregivers, and patients should use a shared decision-making process that accounts for patients' values, preferences, and comorbidities. These recommendations should not be used to limit or deny access to therapies.

Abstract
OBJECTIVE To determine the relationship between serum levels of S100A8/A9 and S100A12 and the maintenance of clinically inactive disease during anti-tumor necrosis factor (anti-TNF) therapy and the occurrence of disease flare following withdrawal of anti-TNF therapy in patients with polyarticular forms of juvenile idiopathic arthritis (JIA). METHODS In this prospective, multicenter study, 137 patients with polyarticular-course JIA whose disease was clinically inactive while receiving anti-TNF therapy were enrolled. Patients were observed for an initial 6-month phase during which anti-TNF treatment was continued. For those patients who maintained clinically inactive disease over the 6 months, anti-TNF was withdrawn and they were followed up for 8 months to assess for the occurrence of flare. Serum S100 levels were measured at baseline and at the time of anti-TNF withdrawal. Spearman's rank correlation test, Mann-Whitney U test, Kruskal-Wallis test, receiver operating characteristic (ROC) curve, and Kaplan-Meier survival analyses were used to assess the relationship between serum S100 levels and maintenance of clinically inactive disease and occurrence of disease flare after anti-TNF withdrawal. RESULTS Over the 6-month initial phase with anti-TNF therapy, the disease state reverted from clinically inactive to clinically active in 24 (18%) of the 130 evaluable patients with polyarticular-course JIA; following anti-TNF withdrawal, 39 (37%) of the 106 evaluable patients experienced a flare. Serum levels of S100A8/A9 and S100A12 were elevated in up to 45% of patients. Results of the ROC analysis revealed that serum S100 levels did not predict maintenance of clinically inactive disease during anti-TNF therapy nor did they predict disease flare after treatment withdrawal. Elevated levels of S100A8/A9 were not predictive of the occurrence of a disease flare within 30 days, 60 days, 90 days, or 8 months following anti-TNF withdrawal, and elevated S100A12 levels had a modest predictive ability for determining the risk of flare within 30, 60, and 90 days after treatment withdrawal. Serum S100A12 levels at the time of anti-TNF withdrawal were inversely correlated with the time to disease flare (r = -0.36). CONCLUSION Serum S100 levels did not predict maintenance of clinically inactive disease or occurrence of disease flare in patients with polyarticular-course JIA, and S100A12 levels were only moderately, and inversely, correlated with the time to disease flare.

Abstract
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.

Abstract
OBJECTIVE The nuclear oncoprotein DEK is an autoantigen associated with juvenile idiopathic arthritis (JIA), especially the oligoarticular subtype. DEK is a secreted chemotactic factor. Abundant levels of DEK and DEK autoantibodies are found in inflamed synovium in JIA. We undertook this study to further characterize the nature of DEK autoantibodies in screening serum samples from 2 different cohorts that consisted mostly of patients with JIA. METHODS DEK autoantibody levels were analyzed in sera from 33 JIA patients, 13 patients with other inflammatory conditions, and 11 healthy controls, as well as in 89 serum samples from JIA patients receiving anti-tumor necrosis factor (anti-TNF) therapy. Recombinant His-tagged full-length DEK protein (1-375 amino acids [aa]) and the 187-375-aa and 1-350-aa His-tagged DEK fragments made in a baculovirus system were used for enzyme-linked immunosorbent assay (ELISA) and immunoblotting. The C-terminal 25-aa fragment of DEK was expressed in a glutathione S-transferase-tagged vector. ELISA results were calculated as area under the curve by the trapezoidal rule. RESULTS DEK autoantibody levels were significantly higher in patients with polyarticular JIA than in those with oligoarticular JIA, and were higher in patients with polyarticular JIA who had more active disease after cessation of anti-TNF therapy. Immunoblotting against the C-terminal 25-aa fragment of DEK confirmed that this section of the DEK molecule is the most immunogenic domain. CONCLUSION DEK autoantibody levels are higher in patients with polyarticular JIA than in those with oligoarticular JIA, and higher in patients who have disease flares after cessation of anti-TNF therapy. The C-terminal 25-aa fragment is the most immunogenic portion of DEK. These findings are significant with respect to the nature of DEK autoantibodies, their contribution to JIA pathogenesis, and their implications for JIA management.

Abstract
The objective of this study was to determine the medical outcomes including the ovarian function childhood-onset SLE (cSLE). The medical records of all patients diagnosed with cSLE in the Greater Cincinnati area between 1981 and 2002 were reviewed. Patient interviews were performed to obtain additional information on current medication regimens, disease activity [SLE Disease Activity Index (SLEDAI-2k)], and damage [Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI)]. The occurence of premature ovarian failure (POF) and reduction of the ovarian reserve was assessed by timed gonadotropin levels. There were 77 patients (F: M = 70: 7, 53% Caucasian, 45% African-American and 2% Asian) with a mean age at diagnosis of 14.6 years. Nine patients died (88.3% survival) during the mean follow-up of 7.1 years (standard deviation [SD] 5.6) and 88% of the patients continued to have active disease (SLEDAI-2k mean/SD: 6.6/6.7), with 42% of them having disease damage (SDI mean/SD: 1.62/2.1); Non-Caucasian patients had higher disease activity (mean SLEDAI-2k: 10 versus 3.4; P < 0.0001) and more disease damage (mean SDI: 2.1 versus 1.2; P < 0.02) than Caucasian patients. Cyclophosphamide was given to 47% of the patients during the course of their disease and associated with the presence of significantly reduced ovarian reserve (RR = 2.8; 95% CI: 1.7-4.8; P = 0.026). Patient mortality and disease damage with cSLE continue to be high. Although overt POF with cyclophosphamide exposure is rare, it is a risk factor for significantly decreased ovarian reserve cSLE.

Abstract
OBJECTIVE The PedsQL rheumatology module is currently the only available measure of disease-specific quality of life for children and adolescents with juvenile fibromyalgia (FM), but limited information has been published about the psychometric properties of the instrument, specifically in juvenile FM. The objective of this study was to assess there liability, validity, and sensitivity to change of the 5 scales (pain and hurt, daily activities, treatment, worry, and communication) of the patient and parent proxy versions of the PedsQL rheumatology module in the context of a randomized controlled trial in juvenile FM. METHODS The entire PedsQL rheumatology module was administered as a supplementary outcome measure at baseline,posttreatment, and 6-month followup assessments of 114 children and adolescents with juvenile FM enrolled in a trial testing the efficacy of cognitive–behavioral therapy. RESULTS Internal consistency reliabilities for the scales were adequate to strong (Cronbach’s α = 0.68–0.86). Parent proxy and child reports on most scales (except for daily activities and communication) showed moderate correlations (Spearman’s r = 0.33–0.45). Support for construct validity was found by comparing child and parent reports with other related measures of pain and functioning (visual analog scale pain ratings and the Functional Disability Inventory). Finally, sensitivity to change was demonstrated by significant changes in 4 of the 5 scales (excluding the daily activities scale) after treatment. CONCLUSION The PedsQL rheumatology module generally appears to have good utility for use in juvenile FM patients, but there are some caveats to the interpretation of specific scales in this population.

Abstract
OBJECTIVE Systemic juvenile idiopathic arthritis (JIA) is characterized by fevers, rash, and arthritis, for which interleukin-1 (IL-1) and IL-6 inhibitors appear to be effective treatments. Pulmonary arterial hypertension (PAH), interstitial lung disease (ILD), and alveolar proteinosis (AP) have recently been reported with increased frequency in systemic JIA patients. Our aim was to characterize and compare systemic JIA patients with these complications to a larger cohort of systemic JIA patients. METHODS Systemic JIA patients who developed PAH, ILD, and/or AP were identified through an electronic Listserv and their demographic, systemic JIA, and pulmonary disease characteristics as well as their medication exposure information were collected. Patients with these features were compared to a cohort of systemic JIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) registry. RESULTS The patients (n = 25) were significantly (P < 0.05) more likely than the CARRA registry cohort (n = 389) to be female; have more systemic features; and have been exposed to an IL-1 inhibitor, tocilizumab, corticosteroids, intravenous immunoglobulin, cyclosporine, and cyclophosphamide. Twenty patients (80%) were diagnosed with pulmonary disease after 2004. Twenty patients (80%) had macrophage activation syndrome (MAS) during their disease course and 15 patients (60%) had MAS at pulmonary diagnosis. Sixteen patients had PAH, 5 had AP, and 7 had ILD. Seventeen patients (68%) were taking or recently discontinued (<1 month) a biologic agent at pulmonary symptom onset; 12 patients (48%) were taking anti-IL-1 therapy (primarily anakinra). Seventeen patients (68%) died at a mean of 10.2 months from the diagnosis of pulmonary complications. CONCLUSION PAH, AP, and ILD are underrecognized complications of systemic JIA that are frequently fatal. These complications may be the result of severe uncontrolled systemic disease activity and may be influenced by medication exposure.

Abstract
THE GOALS OF TREATMENT FOR JUVENILE IDIOPATHIC ARTHRITIS (JIA) INCLUDE: suppression of inflammation, achievement of remission, relief of pain, maintenance of function and doing so with minimal toxicity. Important discoveries over the past 10-15 years have led to more targeted treatments for children with JIA. The International League of Associations for Rheumatology (ILAR) classification system for childhood arthritides, better assessment tools for clinical response, improved definitions of remission, new imaging techniques and evidence in gene expression profiling have all contributed to the development of more targeted treatments. Nonsteroidal anti-inflammatory agents still have a role in mild disease and intra-articular steroid injections continue to be used most commonly in patients with oligoarticular JIA. Disease-modifying agents such as methotrexate have demonstrated efficacy and safety; however, in many patients, the disease remains active despite this treatment. These children now receive more targeted treatment including the tumor necrosis factor alpha (TNFα) inhibitors, interleukin-1 blockade, interleukin-6 blockade, selective costimulation modulators and selective B-cell blockade. The biologic targeted therapies have changed the strategy in which we treat our children with JIA; however, there remains much to be learned about the long-term effects and safety of these medicines.

Abstract
OBJECTIVE Juvenile fibromyalgia syndrome (FMS) is a chronic musculoskeletal pain disorder in children and adolescents for which there are no evidence-based treatments. The objective of this multisite, single-blind, randomized clinical trial was to test whether cognitive-behavioral therapy (CBT) was superior to fibromyalgia (FM) education in reducing functional disability, pain, and symptoms of depression in juvenile FMS. METHODS Participants were 114 adolescents (ages 11-18 years) with juvenile FMS. After receiving stable medications for 8 weeks, patients were randomized to either CBT or FM education and received 8 weekly individual sessions with a therapist and 2 booster sessions. Assessments were conducted at baseline, immediately following the 8-week treatment phase, and at 6-month followup. RESULTS The majority of patients (87.7%) completed the trial per protocol. Intent-to-treat analyses showed that patients in both groups had significant reductions in functional disability, pain, and symptoms of depression at the end of the study, and CBT was significantly superior to FM education in reducing the primary outcome of functional disability (mean baseline to end-of-treatment difference between groups 5.39 [95% confidence interval 1.57, 9.22]). Reduction in symptoms of depression was clinically significant for both groups, with mean scores in the range of normal/nondepressed by the end of the study. Reduction in pain was not clinically significant for either group (<30% decrease in pain). There were no study-related adverse events. CONCLUSION In this controlled trial, CBT was found to be a safe and effective treatment for reducing functional disability and symptoms of depression in adolescents with juvenile FMS.

Abstract
OBJECTIVE The ability to assess quality of care is a necessary component of continuous quality improvement. The assessment typically is accomplished by determination of compliance with a defined set of quality measures (QMs). The objective of this effort was to establish a set of QMs for the assessment of the process of care in juvenile idiopathic arthritis (JIA). METHODS A 12-member working group composed of representatives from the American College of Rheumatology, American Academy of Pediatrics, American Board of Pediatrics, and Association of Rheumatology Health Professionals was assembled to guide the project. Delphi questionnaires were sent to 237 health professionals involved in the care of children with JIA. A total of 471 items in 23 domains were identified. The working group met via 4 live e-meetings during which results from the Delphi questionnaires were distilled to a reduced draft set. Each working group member selected a proposed QM to investigate and present evidence from the literature as to its attributes and appropriateness for inclusion into the set. Nominal group technique was used to come to consensus on a proposed set of QMs. RESULTS The proposed set contains 12 QMs within 4 health care domains. Each QM consists of a statement of 1) the assessment to be completed, 2) when the first assessment should be completed and a suggested frequency of assessment during followup, 3) recommendations of appropriate tools or methods of assessment, and 4) initial performance goals. CONCLUSION Implementation of the proposed QM set will improve the process of care, facilitate continuous quality improvement, and eventuate in improved health outcomes of children with JIA.

Abstract
OBJECTIVE Systemic juvenile idiopathic arthritis (JIA) is associated with macrophage activation syndrome. Macrophage activation syndrome bears a close resemblance to familial hemophagocytic lymphohistiocytosis (HLH). The development of familial HLH has been recently associated with mutations in MUNC13-4. The purpose of this study was to assess for possible sequence alterations in MUNC13-4 in patients with systemic JIA/macrophage activation syndrome. METHODS The MUNC13-4 sequence was analyzed in 18 unrelated patients with systemic JIA/macrophage activation syndrome, using 32 primer pair sets designed to amplify the 32 exons and at least 100 basepairs of the adjacent intronic regions. DNA samples obtained from 73 unrelated patients with systemic JIA and no history of macrophage activation syndrome and 229 unrelated healthy individuals were used as controls. RESULTS The biallelic sequence variants in MUNC13-4 reported in familial HLH were present in 2 of the 18 patients with JIA/macrophage activation syndrome. Further analysis of the MUNC13-4 sequences revealed an identical combination of 12 single-nucleotide polymorphisms (SNPs) in 9 of the remaining 16 patients with systemic JIA/macrophage activation syndrome (56%). Additional analysis suggested that these 12 SNPs (154[-19] g>a, 261[+26] c>g, 388[+81] g>a, 388[+122] c>t, 570[-60] t>g, 888 G>C, 1389[+36] g>a, 1992[+5] g>a, 2447[+144] c>t, 2599 A>G, 2830[+37] c>g, 3198 A>G) were inherited as an extended haplotype. In several patients, in addition to the described haplotype, there were other SNPs in the second allele of MUNC13-4. Moreover, 1 patient had a complex mutation with 2 changes, 2542 A>C and 2943 G>C, in a cis configuration. The haplotype was present in only 27 (12%) of 229 healthy control subjects (chi(2) = 23.5) and in 6 (8.2%) of 73 patients with systemic JIA and no history of macrophage activation syndrome. CONCLUSION The data suggest an association between MUNC13-4 polymorphisms and macrophage activation syndrome in patients with systemic JIA.

Abstract
OBJECTIVE To determine whether neutrophil gelatinase-associated lipocalin (NGAL) can predict worsening of global and renal disease activity in childhood-onset systemic lupus erythematosus (SLE). METHODS One hundred eleven patients with childhood-onset SLE were enrolled in a longitudinal, prospective study with quarterly study visits and had at least 3 study visits. At each visit, global disease activity was measured using 3 external standards: the numerically converted British Isles Lupus Assessment Group (BILAG) index, the SLE Disease Activity Index 2000 update score, and the physician's assessment of global disease activity. Renal and extrarenal disease activity were measured by the respective domain scores. The disease course over time was categorized at the most recent visit (persistently active, persistently inactive, improved, or worsening). Plasma and urinary NGAL levels were measured by enzyme-linked immunosorbent assay, and urinary NGAL levels were standardized to the urinary creatinine concentration. The longitudinal changes in NGAL levels were compared with the changes in SLE disease activity using mixed-effect models. RESULTS Significant increases in standardized urinary NGAL levels of up to 104% were detected up to 3 months before worsening of lupus nephritis (as measured by all 3 external standards). Plasma NGAL levels increased significantly by as much as 26% up to 3 months before worsening of global SLE disease activity as measured by all 3 external standards. Plasma NGAL levels increased significantly by 26% as early as 3 months prior to worsening of lupus nephritis as measured by the BILAG renal score. CONCLUSION Serial measurement of urinary and plasma NGAL levels may be valuable in predicting impending worsening of global and renal childhood-onset SLE disease activity.

Abstract
OBJECTIVES Clinical care and therapeutic trials in idiopathic inflammatory myopathies (IIM) require accurate and consistent assessment of cutaneous involvement. The Cutaneous Assessment Tool (CAT) was designed to measure skin activity and damage in IIM. We describe the development and inter-rater reliability of the CAT, and the frequency of lesions endorsed in a large population of juvenile IIM patients. METHODS The CAT includes 10 activity, 4 damage and 7 combined lesions. Thirty-two photographic slides depicting IIM skin lesions were assessed by 11 raters. One hundred and twenty-three children were assessed by 11 paediatric rheumatologists at 10 centres. Inter-rater reliability was assessed using simple agreements and intra-class correlation coefficients (ICC). RESULTS Simple agreements in recognizing lesions as present or absent were generally high (0.5-1.0). ICCs for CAT lesions were moderate (0.4-0.75) in both slides and real patients. ICCs for the CAT activity and damage scores were 0.71 and 0.81, respectively. CAT activity scores ranged from 0 to 44 (median 7, potential range 0-96) and CAT damage scores ranged from 0 to 13 (median 1, potential range 0-22). The most common cutaneous lesions endorsed were periungual capillary loop changes (63%), Gottron's papules/sign (53%), heliotrope rash (49%) and malar/facial erythema (49%). CONCLUSIONS Total CAT activity and damage scores have moderate to good reliability. Assessors generally agree on the presence of a variety of cutaneous lesions. The CAT is a promising, semi-quantitative tool to comprehensively assess skin disease activity and damage in IIM.

Abstract
OBJECTIVE To provide preliminary validation of the Cutaneous Assessment Tool (CAT), a new tool to assess cutaneous manifestations of juvenile dermatomyositis (DM), and to explore the clinical meaning of CAT scores. METHODS Children with juvenile DM (n = 113) were assessed at baseline and 7-9 months later (n = 94). Internal consistency, redundancy, construct validity, and responsiveness of the CAT were examined. CAT scores corresponding to ordinal global assessments were determined. RESULTS Item-total correlations ranged from 0.27-0.67 for activity lesions present in > or =10% of patients; item-domain and domain-total correlations ranged from 0.25-0.99. Cronbach's alpha was 0.79 for the CAT activity score and 0.74 for the CAT damage score. As predicted, the CAT activity score correlated strongly with both global disease activity and skin disease activity and moderately with the Childhood Myositis Assessment Scale, whereas the CAT damage score correlated moderately with the physician global disease and skin disease damage scores. Median CAT activity scores of 1, 7, 13, 18, and 31 corresponded to absent, mild, moderate, severe, and extremely severe skin disease activity, respectively. Median CAT damage scores of 0, 1, 2, and 5 correlated with the same descriptions of damage (severe and extremely severe combined). CONCLUSION Preliminary validation of the CAT demonstrated good internal consistency, nonredundancy, good construct validity, and appropriate responsiveness. The CAT is a comprehensive, semiquantitative assessment tool for skin disease in juvenile DM.

Abstract
We hypothesized that neutrophil gelatinase-associated lipocalin (NGAL) is an early predictive biomarker of disease activity in lupus nephritis. NGAL in serial plasma (PNGAL) and urine (UNGAL) samples was measured by enzyme-linked immunosorbent assay (ELISA) in 85 participants with pediatric systemic lupus erythematosus (pSLE), healthy children (n = 50), and children with juvenile idiopathic arthritis (JIA) (n = 30). Disease activity was measured by the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Plasma and urinary NGAL were significantly increased in subjects with pSLE compared with those with JIA or with healthy controls (all p < 0.03), and unrelated to subjects' age, weight, or height. Plasma and urinary NGAL were stable in pSLE subjects with unchanged disease activity. The pSLE subjects with worsening global or renal disease activity had a mean +/- standard error (SE) increase of UNGAL (in ng/ml) of 11.5 +/- 6.4 or 36.6 +/- 12.1 (p < 0.01), corresponding to a 156% or 380% increase, respectively. PNGAL increased with worsening disease but to a much lesser degree than UNGAL [global disease activity (mean +/- SE): 7.3 +/- 6.2 or 21%; renal disease activity: 20.2 +/- 6.0 or 51%; both p = not significant]. In conclusion, NGAL in urine but not in plasma represents a novel biomarker for renal disease activity in pSLE.

Abstract
The quest for reliable biomarkers of systemic lupus erythematosus (SLE) nephritis is an area of intense contemporary research. In this study, surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS) technology was used for urinary proteomic profiling of patients with SLE nephritis. Clinical, laboratory, and kidney biopsy data from pediatric patients with SLE (n = 32) were analyzed. Children with juvenile idiopathic arthritis (n = 11) served as controls. SELDI-TOF-MS was performed using ProteinChips with different chromatographic surfaces. The resulting spectra were analyzed with Bio-Rad Biomarker Wizard software. A consistent urinary proteomic signature for SLE nephritis was found, comprising eight biomarker proteins with peaks at m/z of 2.7, 22, 23, 44, 56, 79, 100, and 133 kDa. The peak intensities of these biomarkers were significantly greater in patients with SLE nephritis compared with controls and SLE patients without nephritis. These biomarkers were strongly correlated with renal disease activity and moderately with renal damage. For the diagnosis of active nephritis, the area under the receiver operating characteristic curve was > or =0.90 for 22, 23, 44, 79, and 100 kDa biomarkers. Thus, SELDI-TOF-MS has identified a urine proteomic signature strongly associated with SLE renal involvement and active SLE nephritis.

Abstract
OBJECTIVE To assess the reliability and concurrent validity of the Medication Adherence Self-report Inventory (MASRI) when used in systemic lupus erythematosus (SLE), to investigate the predictive validity of the MASRI using pharmacy refill information as the criterion standard, and to propose a sensible approach to the screening for nonadherence in a clinical setting. METHODS Adherence to 2 medications (hydroxychloroquine and prednisone) was measured in 55 patients using the MASRI, pill counts, and physician ratings (MD scale). Adherence based on pharmacy refill information served as a criterion standard with nonadherence defined as adherence rates <80%. To determine test-rest reliability of the MASRI, 20 patients completed the measure twice within a 2-week period. RESULTS Using pharmacy information, 39% of the patients were nonadherent to prednisone and 51% to hydroxychloroquine. The MASRI had acceptable internal consistency (Cronbach's alpha 0.7) and good reliability. Irrespective of the drug assessed, MASRI ratings were moderately correlated with patient adherence (pharmacy), supporting the concurrent validity of the MASRI. The combination of adherence estimation by MD scale rating at <85% and by MASRI at <90% was 87% sensitive and 86% specific for identifying patients who were nonadherent to prednisone. These cutoff values also appeared suitable for identifying nonadherence to hydroxychloroquine. CONCLUSION The MASRI is a reliable measure of adherence to medications in SLE. The measure has concurrent and predictive validity. When combined with the MD scale, the MASRI appears to be a useful screening tool for nonadherence in patients with SLE that could be suitable for clinical practice.

Abstract
OBJECTIVE Macrophage activation syndrome is characterized by an overwhelming inflammatory reaction driven by excessive expansion of T cells and hemophagocytic macrophages. Levels of soluble interleukin-2 receptor alpha (sIL-2Ralpha) and soluble CD163 (sCD163) may reflect the degree of activation and expansion of T cells and macrophages, respectively. This study was undertaken to assess the value of serum sIL-2Ralpha and sCD163 in diagnosing acute macrophage activation syndrome complicating systemic juvenile idiopathic arthritis (JIA). METHODS Enzyme-linked immunosorbent assay was used to assess sIL-2Ralpha and sCD163 levels in sera from 7 patients with acute macrophage activation syndrome complicating systemic JIA and 16 patients with untreated new-onset systemic JIA. The results were correlated with clinical features of established macrophage activation syndrome, including ferritin levels. RESULTS The median level of sIL-2Ralpha in the patients with macrophage activation syndrome was 19,646 pg/ml (interquartile range [IQR] 18,128), compared with 3,787 pg/ml (IQR 3,762) in patients with systemic JIA (P = 0.003). Similarly, the median level of sCD163 in patients with macrophage activation syndrome was 23,000 ng/ml (IQR 14,191), compared with 5,480 ng/ml (IQR 2,635) in patients with systemic JIA (P = 0.017). In 5 of 16 patients with systemic JIA, serum levels of sIL-2Ralpha or sCD163 were comparable with those in patients with acute macrophage activation syndrome. These patients had high inflammatory activity associated with a trend toward lower hemoglobin levels (P = 0.11), lower platelet counts, and significantly higher ferritin levels (P = 0.02). Two of these 5 patients developed overt macrophage activation syndrome several months later. CONCLUSION Levels of sIL-2Ralpha and sCD163 are promising diagnostic markers for macrophage activation syndrome. They may also help identify patients with subclinical macrophage activation syndrome.

Abstract
OBJECTIVE To evaluate the concurrent validity and diagnostic accuracy of the pediatric Automated Neuropsychological Assessment Metrics (Ped-ANAM) when used in childhood-onset systemic lupus erythematosus (SLE). METHODS Formal neuropsychological testing and the Ped-ANAM were performed on 27 children with SLE who had not been previously diagnosed with neuropsychiatric SLE. Performance when completing the 10 Ped-ANAM tests was based on accuracy (AC), mean time to correct response, coefficient of variation of the time required for a correct response (CVc), and throughput. Formal neuropsychological testing was used as a criterion standard for diagnosing neurocognitive dysfunction (NCD; yes/no). RESULTS NCD was common and present in 16 (59%) of 27 participants. Ped-ANAM performance parameters were often moderately correlated with the Z scores on formal neuropsychological testing. The NCD group differed significantly (P < 0.05) from the normal cognition group in 3 Ped-ANAM tests: CVc with mathematical processing (MTH-CVc), AC with continuous performance test (CPT-AC), and CVc with spatial processing (SPD-CVc). Areas under the receiver operating curves (AUCs) ranged between 0.75 and 0.84 when each of these parameters (CPT-AC, MTH-CVc, SPD-CVc) was used to identify NCD independently. The AUC was improved to 0.96 for the combined assessment. CONCLUSION The Ped-ANAM has concurrent validity when used in children with SLE. Initial validation suggests that the Ped-ANAM could be a useful screening tool for NCD in children with SLE.

Abstract
In the last 20 years, the clinician educator has become an integral, indispensable part of the academic team. Competition for clinical revenue and increased rigor of mandating physician competency and evidenced-based treatments have created a niche in academia in which the clinician educator can thrive. Academic clinician educators are needed in adult and pediatric rheumatology. A two-tiered system for promotion exists: research and publication are still rewarded faster and acknowledged more than teaching and excellence in clinical care. Clinician educators must be better prepared for teaching, stimulated to create new curricula and methods of evaluation, and provided opportunities to publish their work. Faculty development programs and advanced degrees in education are essential, and promotion criteria must be modified. Clinician educators have a place in academia, but they must continue to thrive as master clinicians, innovators in competency-based teaching methods and evaluation, and contributors to the literature.

Abstract
OBJECTIVE Renal involvement in systemic lupus erythematosus (SLE) is associated with poor prognosis. Currently available renal biomarkers are relatively insensitive and nonspecific for diagnosing SLE nephritis. Previous research suggests that neutrophil gelatinase-associated lipocalin (NGAL) is a high-quality renal biomarker of acute kidney injury, while its usefulness in SLE is unclear. We undertook this study to determine the relationship between urinary NGAL excretion and SLE disease activity or damage, with a focus on nephritis. METHODS A cohort of 35 patients diagnosed as having SLE prior to age 16 years (childhood-onset SLE) was assessed for disease activity (using the Systemic Lupus Erythematosus Disease Activity Index 2000 update) and damage (using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology SLE Damage Index) in a double-blind, cross-sectional study. Information on current markers of renal function and disease was obtained and compared with NGAL levels (ng/mg of urinary creatinine) measured by enzyme-linked immunosorbent assay. Eight children with juvenile idiopathic arthritis (JIA) served as controls. RESULTS NGAL levels did not differ with the age, weight, height, sex, or race of the patients. Patients with childhood-onset SLE had significantly higher NGAL levels than did those with JIA (P < 0.0001). NGAL levels were strongly to moderately correlated with renal disease activity and renal damage (Spearman's r >/= 0.47, P < 0.0001 for both comparisons), but not with extrarenal disease activity or extrarenal damage. NGAL levels of >0.6 ng/mg urinary creatinine were 90% sensitive and 100% specific for identifying childhood-onset SLE patients with biopsy-proven nephritis. CONCLUSION Urinary NGAL is a promising potential biomarker of childhood-onset SLE nephritis. The results of the current study require validation in a larger cohort to more accurately delineate urinary NGAL excretion in relation to the diverse SLE phenotypes.

Abstract
OBJECTIVE To determine the relationship between health insurance status and disease outcome in children with juvenile rheumatoid arthritis (JRA). METHODS JRA patients followed at a tertiary pediatric rheumatology center were assessed for the number of active joints and number of joints with limited range of motion. Disease activity, patient well-being, and pain were measured. Disability was assessed by the Childhood Health Assessment Questionnaire, health-related quality of life by the Pediatric Quality of Life Inventory (PedsQL) Generic Core Scale, and the PedsQL Rheumatology Module. Health care resource utilization was estimated based on the number of billing events for health services coded in administrative databases; these databases also provided information on patient health insurance status. Children insured by Medicaid or similar state programs for low-income families were considered to have Medicaid status. Disease outcomes of children with Medicaid status was compared with that of children with private health insurance. RESULTS Forty (14%) of the 295 children with JRA had Medicaid status. Patients with Medicaid status were more often of nonwhite race (P < or = 0.04) and more frequently had a polyarticular or systemic disease course (P = 0.04) compared with other patients (n = 255). After correction for differences in disease duration, race, JRA onset, and JRA course between groups, children with Medicaid status continued to have significantly higher disability (P < 0.0003), and lower mean PedsQL Generic Core Scale scores (P < 0.05), while health resource utilization appeared similar between groups. CONCLUSION Despite apparently similar health resource utilization and joint involvement, Medicaid status is associated with significantly lower health-related quality of life and higher disability in JRA.

Abstract
OBJECTIVE To correlate disease course and complications in children with juvenile dermatomyositis (JDM) and polymyositis (JPM) with specific features of muscle pathology on biopsy. METHODS This is a retrospective cohort analysis of 59 children diagnosed with JDM or JPM between 1965 and 1998 and followed at the Cincinnati Children's Hospital Medical Center (CCHMC) for a mean duration of 7.3 years (range 1.1-24.5 years). Disease course was characterized as limited, chronic non-ulcerative or chronic ulcerative, similar to previously defined disease course subtypes reported by Crowe et al.(1). All subjects had diagnostic muscle biopsies performed at CCHMC and had disease for at least two years' duration in order to classify their disease course as either limited or chronic. Features of muscle histopathology that were evaluated included loss of the intramuscular capillary bed, infarct, perifascicular myopathy, direct immunofluorescence (DIF) staining of the intramuscular vasculature and specifically, the locale of DIF staining, i.e., small arteries or capillaries. Disease complications that were assessed included calcinosis, contractures, muscle atrophy, lipodystrophy, gastrointestinal ulceration, cutaneous ulceration and death. Data analysis was completed using Chi-square or Fisher's exact tests and logistic regression modeling. RESULTS Twenty-two children (37%) had limited disease, 24 (41%) had chronic non-ulcerative disease and 13 (22%) had chronic ulcerative disease. Neither loss of the intramuscular capillary bed nor perifascicular myopathy on muscle biopsy significantly correlated with disease course or the various complications evaluated in this study. DIF staining of intramuscular vessels overall was not significantly associated with clinical disease course, but the localization of DIF staining to intramuscular arteries (rather than to capillaries) was significantly associated with the outcome of chronic ulcerative disease. Nine of the 13 children with chronic ulcerative disease had DIF-arterial staining on muscle biopsy (69%), significantly greater than DIF-arterial staining in children with limited disease (32% had DIF-arterial staining) (p = 0.04), chronic non-ulcerative disease (8% had DIF-arterial staining) (p = 0.0002), and non-ulcerative disease overall (limited + chronic non-ulcerative disease groups combined) (20% had DIF-arterial staining), with p = 0.001. Additionally, lack of DIF-arterial staining on biopsy was significantly correlated with patients not having gastrointestinal ulceration (p = 0.002), cutaneous ulceration (p = 0.004) and/or death (p = 0.02) as disease-related complications. Infarct on muscle biopsy was significantly associated with the development of chronic ulcerative disease (p = 0.02), being present on biopsy in 23% of children with chronic ulcerative disease compared with none of the patients with chronic non-ulcerative disease and 4% of those with limited disease. Infarct on muscle biopsy correlated with the outcomes of death (p = 0.01) and gastrointestinal ulceration (p = 0.03), but not with the development of cutaneous ulceration (p = 0.18). CONCLUSION DIF-arterial staining and infarct on muscle biopsy are significantly associated with the development of chronic ulcerative disease in JDM and JPM, while perifascicular myopathy and loss of the intramuscular capillary network are not associated with disease course. The presence of DIF-arterial staining and infarct on biopsy should suggest early use of second-line therapeutic agents to more quickly bring disease activity under control.

Abstract
OBJECTIVES The objectives of this study were to perform an initial validation of the Gastrointestinal Symptom Scale for Kids (GISSK) in children with juvenile rheumatoid arthritis (JRA); and too evaluate the relationship between gastrointestinal (GI) symptoms and health-related quality of life (HRQOL) in JRA. METHODS A convenience sample of 77 children (median age, 10 years; range, 2-18 years) with JRA requiring second-line agents and one of their parents were interviewed. GI symptoms during the preceding 1 week were measured using the GISSK, which consists of 2 components, a visual analog scale of GI symptom severity (GISSK-VAS) and an 8-item questionnaire (GISSK-Q; score 0-8; 0= no GI symptoms). Information on medications, joint involvement with arthritis, and a physician rating of disease activity were obtained. Patient-centered outcomes included the Childhood Health Assessment Questionnaire (CHAQ) to assess disability and discomfort. HRQOL was measured by the Pediatric Quality of Life Generic Core Scale (PedsQL-GC) and the Rheumatology Module (PedsQL-RM), as well as a visual analog scale (VAS-health). To determine test-retest reliability, the GISSK was completed by 40 parents twice within a 1- to 2-week period. To determine the quality of parent proxy-reporting, parent ratings were compared with those of their children aged 8 years or older. RESULTS GI symptoms were present in the majority of the patients with JRA (58%). Compared with other patients with JRA, those with a GISSK-Q score of > or =2 had significantly lower HRQOL (PedsQL-GC: P < 0.04; PedsQL-RM: P < 0.05; VAS-health: P < 0.02) and more disability (CHAQ: P < 0.002), despite similar disease activity and joint findings. Similar relationships were observed for the GISSK-VAS with traditional outcomes and HRQOL. The test-retest reliability of the GISSK was good (ICCGISSK-Q = 0.60; ICCGISSK-VAS = 0.67). The quality of parent proxy-reporting was fair to good (ICCGISSK-Q = 0.47; ICCGISSK-VAS = 0.66). CONCLUSION GI symptoms are frequent among children with JRA requiring advanced therapies and, if moderate or severe, are associated with significantly lower HRQOL. The GISSK is a reliable and valid measure of GI symptoms and their severity in JRA. This self-administered measure can be used to screen for GI symptoms in clinical practice and may be useful to assess the effects of medication changes on the perceived GI side effects in children with JRA.

Abstract
OBJECTIVE To examine the strength of the association between different measures of health-related quality of life (HRQOL), disability, pain, and well-being in children with chronic arthritis. To evaluate whether HRQOL scores vary as a function of disability status beyond chance. To assess the quality of the parent proxy report for HRQOL as compared with disability, pain, and well-being. METHODS Measures of HRQOL (visual analog scale [VAS] of health, Pediatric Quality of Life Inventory [PedsQL], Juvenile Arthritis Quality of Life Questionnaire (JAQQ), and modified standard gamble technique [SG]), disability (Childhood Health Assessment Questionnaire), VAS of pain, and VAS of well-being (VAS-well) were completed by the parents (n = 119) and patients > or =8 years (SG: > or =12 years). RESULTS HRQOL was highest when measured by the SG, whose utilities were no more than weakly correlated with any of the other outcomes. The values of all other HRQOL measures were at least moderately correlated with each other and with the VAS-well. Irrespective of the measure used, disability was associated with significantly decreased HRQOL. There was fair to good agreement and moderate consistency of the HRQOL ratings (SG: fair consistency) between patients and parents with marked differences between health domains. CONCLUSION HRQOL measured by the PedsQL, JAQQ, and VAS are moderately to highly correlated with each other in children with chronic arthritis. The children's HRQOL significantly decreases with increasing disability. Despite more pronounced differences for some health domains, parents are moderate to good proxy reporters of HRQOL, disability, and well-being of children with chronic arthritis.

Abstract
OBJECTIVE To assess for novel markers of muscle damage using urinary muscle metabolites by 1H magnetic resonance spectroscopy in patients with juvenile idiopathic inflammatory myopathy (IIM). METHODS Creatine (Cr), choline (Cho), betaine (Bet), glycine (Gly), trimethylamine oxide (TMAO), and several other metabolites were measured in first morning void urine samples from 45 patients with juvenile IIM and from 35 healthy age-matched controls, and correlated with measures of myositis disease activity and damage. Urinary metabolite to age-adjusted creatinine (Cn) ratios were examined. RESULTS Age-adjusted initial Cr:Cn, Cho:Cn, Bet:Cn, Gly:Cn, and TMAO:Cn ratios were higher in patients with juvenile IIM than controls (P < 0.01). Cr:Cn ratios showed significant correlations with physician-assessed global disease damage (Spearman rs = 0.37; P = 0.01), Steinbrocker functional class (rs = 0.35; P = 0.02), serum Cr (rs = 0.72; P = 0.001), and lactate dehydrogenase (rs = 0.34; P = 0.03) levels. Cho:Cn (rs = 0.3; P = 0.05), Gly:Cn (rs = 0.33; P = 0.03), and TMAO:Cn (rs = 0.36; P = 0.02) ratios showed a significant correlation with serum aldolase levels. Cho:Cn ratios also showed a significant correlation with aspartate aminotransferase levels (rs = 0.35; P = 0.02). A linear regression model was used to evaluate the factors influencing urinary Cr:Cn ratios in the 43 patients with data sets available at the initial visit. The regression model explained 73% of the variation in Cr:Cn ratios. The most significant factor was the physician-assessed global disease damage (R2 = 0.50, P = 0.015). CONCLUSION Urinary Cr:Cn, Cho:Cn, Bet:Cn, Gly:Cn, and TMAO:Cn ratios are elevated in juvenile IIM and Cr:Cn correlates strongly with global disease damage. The Cr:Cn ratio may have potential utility as a marker of myositis disease damage.

Abstract
OBJECTIVE To assess the feasibility and construct validity of the willingness-to-pay (WTP) technique for measuring health care preferences in families of children with juvenile idiopathic arthritis (JIA). METHODS Parents were asked to estimate the monthly US dollar amount they would be willing to pay to obtain for their child the following hypothetical drugs: ARTHRO, which guarantees complete clinical response; and NO-STOM-ACHE, a drug that eliminates gastrointestinal (GI) symptoms. A yes/no question was used with random assignment of the starting bids. Parents who agreed to pay the starting bid were then asked whether they would be willing to pay 200% and then 400% of this initial bid. Socioeconomic data and information on medications, disease activity, patient physical function, wellbeing, and health-related quality of life (HRQOL) were obtained. RESULTS Sixty-two families of children with JIA were interviewed. GI symptoms were present in 54%, and 53% of the children had joints with active arthritis or limited range of motion. Four parents (7%) were unwilling to pay anything for any of the studied medications. The mean amount (median; mean percentage of available family income) families were willing to pay was $395 ($300; 15%) for ARTHRO and $109 ($80; 4%) for NO-STOM-ACHE. Correlation and regression analysis supported that, adjusted for the available family income, the WTP for ARTHRO was associated with disease activity, pain, and the HRQOL of the patients. After correction for the starting bids and the available family income, the WTP for NO-STOM-ACHE was associated with the patient's HRQOL, pain, and the amount of GI discomfort. CONCLUSION The WTP technique is feasible and has construct validity for measuring health care preferences for children with JIA. Relatively large WTP estimates support a possible important negative impact of the disease on families of children with JIA.

Abstract
Macrophage activation syndrome (MAS) has been reported in association with many rheumatic diseases, most commonly in systemic juvenile rheumatoid arthritis (sJRA). Clinically, MAS is similar to hemophagocytic lymphohistiocytosis (HLH), a genetic disorder with absent or depressed natural killer (NK) function. We have previously reported that, as in HLH, patients with MAS have profoundly decreased NK activity, suggesting that this abnormality might be relevant to the pathogenesis of the syndrome. Here we examined the extent of NK dysfunction across the spectrum of diseases that comprise juvenile rheumatoid arthritis (JRA). Peripheral blood mononuclear cells (PBMC) were collected from patients with pauciarticular (n = 4), polyarticular (n = 16), and systemic (n = 20) forms of JRA. NK cytolytic activity was measured after co-incubation of PBMC with the NK-sensitive K562 cell line. NK cells (CD56+/T cell receptor [TCR]-αβ-), NK T cells (CD56+/TCR-αβ+), and CD8+ T cells were also assessed for perforin and granzyme B expression by flow cytometry. Overall, NK cytolytic activity was significantly lower in patients with sJRA than in other JRA patients and controls. In a subgroup of patients with predominantly sJRA, NK cell activity was profoundly decreased: in 10 of 20 patients with sJRA and in only 1 of 20 patients with other JRA, levels of NK activity were below two standard deviations of pediatric controls (P = 0.002). Some decrease in perforin expression in NK cells and cytotoxic T lymphocytes was seen in patients within each of the JRA groups with no statistically significant differences. There was a profound decrease in the proportion of circulating CD56bright NK cells in three sJRA patients, a pattern similar to that previously observed in MAS and HLH. In conclusion, a subgroup of patients with JRA who have not yet had an episode of MAS showed decreased NK function and an absence of circulating CD56bright population, similar to the abnormalities observed in patients with MAS and HLH. This phenomenon was particularly common in the systemic form of JRA, a clinical entity strongly associated with MAS.

Abstract
OBJECTIVE To document and evaluate the scores that normal, healthy children achieve when performing 9 maneuvers of the Childhood Myositis Assessment Scale (CMAS). METHODS A total of 303 healthy children, 4-9 years of age, were scored as they performed 9 CMAS maneuvers. The data were then evaluated to determine whether normal scores for some maneuvers are age and sex dependent. RESULTS All children were able to achieve maximum possible scores for the supine to prone, supine to sit, floor sit, floor rise, and chair rise maneuvers. All but 2 4-year-olds achieved a maximum possible score for the arm raise/duration maneuver. Performance of the head lift and sit-up maneuvers varied significantly, depending primarily on age. Children in all age groups had less difficulty performing the leg lift than the head lift or sit-up. CONCLUSION The normative data generated by this study are of value for interpreting the serial CMAS scores of children with idiopathic inflammatory myopathies.

Abstract
OBJECTIVE To examine the measurement characteristics of the Childhood Myositis Assessment Scale (CMAS) in children with juvenile idiopathic inflammatory myopathy (juvenile IIM), and to obtain preliminary data on the clinical significance of CMAS scores. METHODS One hundred eight children with juvenile IIM were evaluated on 2 occasions, 7-9 months apart, using various measures of physical function, strength, and disease activity. Interrater reliability, construct validity, and responsiveness of the CMAS were examined. The minimum clinically important difference (MID) and CMAS scores corresponding to various degrees of physical disability were estimated. RESULTS The intraclass correlation coefficient for 26 patients assessed by 2 examiners was 0.89, indicating very good interrater reliability. The CMAS score correlated highly with the Childhood Health Assessment Questionnaire (C-HAQ) score and with findings on manual muscle testing (MMT) (r(s) = -0.73 and 0.73, respectively) and moderately with physician-assessed global disease activity and skin activity, parent-assessed global disease severity, and muscle magnetic resonance imaging (r(s) = -0.44 to -0.61), thereby demonstrating good construct validity. The standardized response mean was 0.81 (95% confidence interval 0.53, 1.09) in patients with at least 0.8 cm improvement on a 10-cm visual analog scale for physician-assessed global disease activity, indicating strong responsiveness. In bivariate regression models predicting physician-assessed global disease activity, MMT remained significant in models containing the CMAS (P = 0.03) while the C-HAQ did not (P = 0.4). Estimates of the MID ranged from 1.5 to 3.0 points on a 0-52-point scale. CMAS scores corresponding to no, mild, mild-to-moderate, and moderate physical disability, respectively, were 48, 45, 39, and 30. CONCLUSION The CMAS exhibits good reliability, construct validity, and responsiveness, and is therefore a valid instrument for the assessment of physical function, muscle strength, and endurance in children with juvenile IIM. Preliminary data on MID and corresponding levels of disability should aid in the clinical interpretation of CMAS scores when assessing patients with juvenile IIM.

Abstract
OBJECTIVE To evaluate the ability of microarray-based methods to identify genes with disease-specific expression patterns in peripheral blood mononuclear cells (PBMC) and synovial fluid mononuclear cells (SFMC) of juvenile arthritis patients and healthy controls. METHODS Microarray data (Affymetrix U95Av2) from 26 PBMC and 20 SFMC samples collected from patients with active disease (classified by course according to ACR criteria) were analysed for expression patterns that correlated with disease characteristics. For comparison, PBMC gene expression profiles were obtained from 15 healthy controls. Real-time PCR was used for confirmation of gene expression differences. RESULTS Statistical analysis of gene expression patterns in PBMC identified 378 probe sets corresponding to 342 unique genes with differing expression levels between polyarticular course patients and controls (t test, P<0.0001). The genes represented by these probe sets were enriched for functions related to regulation of immune cell functions, receptor signalling as well as protein metabolism and degradation. Included in these probe sets were a group of CXCL chemokines with functions related to angiogenesis. Further analysis showed that, whereas angiogenic CXCL (ELR+) gene expression was elevated in polyarticular PBMC, expression of angiostatic CXCL (ELR-) chemokines was lower in polyarticular SFMC compared with corresponding pauciarticular samples (t test, P<0.05). CONCLUSIONS This pilot study demonstrates that juvenile arthritis patients exhibit complex patterns of gene expression in PBMC and SFMC. The presence of disease-correlated biologically relevant gene expression patterns suggests that the power of this approach will allow better understanding of disease mechanisms, identify distinct clinical phenotypes in disease subtypes, and suggest new therapeutic approaches.

Abstract
OBJECTIVES To assess natural killer (NK) and cytotoxic functions in patients with systemic-onset juvenile rheumatoid arthrithis (soJRA) complicated by macrophage activation syndrome (MAS). METHODS NK cells (CD56+/TCRalphabeta-), NK T cells (CD56+/TCRalphabeta+) and CD8+ cells were assessed for perforin expression by flow cytometry. NK cytotoxic activity was measured after coincubation of mononuclear cells with an NK-sensitive K562 cell line. RESULTS Two major patterns of immunologic abnormalities were detected. Four of 7 patients had decreased NK activity, low NK cell numbers, and mildly increased levels of perforin expression in CD8+ and CD56+ cytotoxic cells. Three remaining patients with MAS, however, had decreased NK activity associated with low levels of perforin expression in all cytotoxic cell populations, a pattern indistinguishable from that in carriers of perforin-deficient familial hemophagocytic lymphohistiocytosis. Remarkably, two of these patients had previous episodes of MAS. CONCLUSIONS NK dysfunction is an immunologic abnormality common to both familial hemophagocytic lymphohistiocytosis and MAS of soJRA. The extent of NK cell abnormalities in soJRA needs to be further investigated.

Abstract
OBJECTIVE To complete an assessment of social functioning of children with juvenile rheumatoid arthritis (JRA) and nonchronically ill controls who had been evaluated 2 years earlier (Noll et al., 2000) and to examine the impact of disease severity or disease activity over time on the social functioning of children with JRA. METHODS Peer-, teacher-, and self-reports of social functioning were obtained from 57 children with JRA and 63 controls. Social reputation and social acceptance were examined cross-sectionally and longitudinally. RESULTS Cross-sectional analyses indicated no significant differences between children with JRA and controls on measures of social functioning. For children with more severe disease, like ratings declined over the 2-year period relative to children with mild disease. Children with active disease were chosen fewer times over the 2-year period as a best friend than children in remission. CONCLUSIONS Because children with severe or active JRA may be at risk for difficulties with social acceptance over time, they are appropriate targets for interventions that ameliorate or prevent these difficulties.

Abstract
OBJECTIVE We evaluated the utility of neopterin and quinolinic acid (QUIN) as surrogate measures of disease activity in juvenile idiopathic inflammatory myopathies (IIMs). METHODS Plasma and first morning void urine samples were measured for neopterin and QUIN using commercial ELISA, HPLC, or gas chromatography-mass spectrometry in 45 juvenile IIM patients and 79 healthy controls. Myositis disease activity assessments were obtained. RESULTS Plasma and urine neopterin and QUIN concentrations were increased in juvenile IIM patients compared with healthy controls (P <0.017). Urine neopterin and QUIN highly correlated with each other (r(s) = 0.73; P <0.0001). Urine neopterin and QUIN correlated moderately with myositis disease activity assessments, including physician and parent global activity assessments, muscle strength testing, functional assessments (Childhood Myositis Assessment Scale, Childhood Health Assessment Questionnaire), skin global activity, and edema on magnetic resonance imaging (r(s) = 0.42-0.62; P <0.05), but generally not with muscle-associated enzymes in serum. Urine neopterin or QUIN, in combination with either serum lactate dehydrogenase (LD) or aspartate aminotransferase (AST), significantly predicted global disease activity (R(2) =0.40-0.56; P <0.002), and both were more sensitive to change than these serum enzymes (standardized response means, -0.41 to -0.48). CONCLUSIONS Urinary neopterin and QUIN are candidate measures of disease activity in juvenile IIM patients and add significantly to the prediction of global disease activity in combination with serum LD or AST values. Measurement of these markers in first morning void urine specimens appears to be as good as, or possibly better than, measurements of their concentrations in plasma.

Abstract
Progress in achieving international consensus concerning the classification of juvenile idiopathic arthritis has been made, although further refinement and validation of these criteria is needed. It is hoped that this will facilitate more effective international collaboration in the study of these diseases, because much remains to be learned about genetic susceptibility, causation, pathogenesis, and treatment. Attention to the unique aspects of chronic arthritis in children such as impaired growth and macrophage activation syndrome may help to reduce disease-related morbidity and mortality. New biologic agents have substantially enhanced the treatment of JRA. The identification of reliable predictors of disease course and outcome is important in the rational and timely application of new therapies.

Abstract
OBJECTIVE To compare synovial tissue cytokine mRNA expression between patients with juvenile rheumatoid arthritis (JRA) and a heterogeneous group of non-autoimmune arthropathies (controls) with respect to type 1/type 2 balance. METHODS Thirty-five JRA (average 9.1 years' disease duration) and 13 control synovial tissues were studied. As a measure of the type 1/type 2 cytokine balance in a subset of the JRA and control tissues, interferon-gamma (IFN-gamma) and interleukin 4 (IL-4) mRNA levels were measured by competitive fragment reverse transcription-polymerase chain reaction. To quantitate additional cytokines relevant to this balance, multiprobe ribonuclease protection assays were employed measuring IL-5, IL-10, IL-13, IL-15, IL-18, and IL-12 (p35 and p40 subunits). Immunohistochemistry was performed on JRA tissues using antibodies specific for IL-15 and IL-18. RESULTS A higher IFN-gamma:IL-4 ratio (p = 0.034) was found in JRA tissues compared to controls. JRA tissues also displayed higher mRNA levels of IL-12p35 (p = 0.021), IL-15 (p = 0.002), and IL-18 (p = 0.017), but not IL-4 and IL-10. IFN-gamma expression in JRA, but not controls, correlated strongly with IL-12p35 (r = 0.63) and IL-12p40 (r = 0.73) levels. A subset of IL-15+ and IL-18+ cells was detected in JRA synovial tissues, largely within perivascular aggregates. CONCLUSION JRA synovial tissue cytokine expression patterns indicate a type 1 bias, even in the later stages of disease. The strong correlation between IFN-gamma and IL-12 in JRA suggests a prominent role for IL-12 in promoting the type I bias, while IL-15 and IL-18 may also indirectly increase IFN-gamma expression and further bias the immune response.

Abstract
The documentation of treatments used for Juvenile Rheumatoid Arthritis (JRA) is important to allow for the evaluation of practice patterns for future outcome studies. A survey of nine pediatric rheumatologists was performed between September 1999 and February 2000. Each of the physicians prospectively recorded demographic and treatment information on consecutively sampled JRA patients (n=395). Pauciarticular onset JRA was present in 46%, polyarticular onset JRA in 35%, and systemic onset JRA in 19% of the children. Naproxen was the most frequently prescribed medication (55% of the patients), followed by methotrexate (MTX), which was used in 39% of the patients. Folic acid supplementation (1 mg/day) was provided to 69% of the patients treated with MTX. Etanercept was used in 11% of the children. Eleven percent of the patients received corticosteroids, and 13% of children on corticosteroids took calcium supplements. Uveitis was present in 8% and had a chronic course in 79% of those cases. Although systemic medications were used in 50% of the children with uveitis to control eye inflammation, severe damage to the eyes developed in 30% of them. Fourteen percent of the patients required gastroprotective medications. Compared with findings of a similar survey performed in 1993, there was no significant change in the frequency of use of naproxen, but nabumetone is now more often prescribed, and COX-2 inhibitors have been introduced in the therapy of JRA. Changes among second-line agents used for JRA have also occurred, although there was no change in the frequency of use of MTX or corticosteroids. JRA continues to be a treatment challenge for the practicing pediatric rheumatologist. Patients often show incomplete response to the currently available medications. Therefore, new therapeutic agents need to be evaluated for their use in JRA, and the treatment of JRA associated uveitis especially needs to be improved.
