RESUMO

BACKGROUND: Rare autoinflammatory diseases (AIDs) including Cryopyrin-Associated Periodic Syndrome (CAPS), Tumor Necrosis Receptor-Associated Periodic Syndrome (TRAPS) and Mevalonate Kinase Deficiency Syndrome (MKD)/ Hyper-IgD Syndrome (HIDS) are genetically defined and characterized by recurrent fever episodes and inflammatory organ manifestations. Early diagnosis and early start of effective therapies control the inflammation and prevent organ damage. The PRO-KIND initiative of the German Society of Pediatric Rheumatology (GKJR) aims to harmonize the diagnosis and management of children with rheumatic diseases nationally. The task of the PRO-KIND CAPS/TRAPS/MKD/HIDS working group was to develop evidence-based, consensus diagnosis and management protocols including the first AID treat-to-target strategies. METHODS: The national CAPS/TRAPS/MKD/HIDS expert working group was established, defined its aims and conducted a comprehensive literature review synthesising the recent (2013 to 2018) published evidence including all available recommendations for diagnosis and management. General and disease-specific statements were anchored in the 2015 SHARE recommendations. An iterative expert review process discussed, adapted and refined these statements. Ultimately the GKJR membership vetted the proposed consensus statements, agreement of 80% was mandatory for inclusion. The approved statements were integrated into three disease specific consensus treatment plans (CTPs). These were developed to enable the implementation of evidence-based, standardized care into clinical practice. RESULTS: The CAPS/TRAPS/MKD/HIDS expert working group of 12 German and Austrian paediatric rheumatologists completed the evidence synthesis and modified a total of 38 statements based on the SHARE recommendation framework. In iterative reviews 36 reached the mandatory agreement threshold of 80% in the final GKJR member survey. These included 9 overarching principles and 27 disease-specific statements (7 for CAPS, 11 TRAPS, 9 MKD/HIDS). A diagnostic algorithm was established based on the synthesized evidence. Statements were integrated into diagnosis- and disease activity specific treat-to-target CTPs for CAPS, TRAPS and MKD/HIDS. CONCLUSIONS: The PRO-KIND CAPS/TRAPS/MKD/HIDS working group established the first evidence-based, actionable treat-to-target consensus treatment plans for three rare hereditary autoinflammatory diseases. These provide a path to a rapid evaluation, effective control of disease activity and tailored adjustment of therapies. Their implementation will decrease variation in care and optimize health outcomes for children with AID.

RESUMO

OBJECTIVE: Using data from the German Biologics JIA Registry (BIKER), long-term safety of biologics for systemic-onset JIA with regard to adverse events of special interest was assessed. METHODS: Safety assessments were based on adverse event reports after first dose through 90 days after last dose. Rates of adverse event, serious adverse event and 25 predefined adverse events of special interest were analysed. Incidence rates were compared for each biologic against all other biologics combined applying a mixed-effect Poisson model. RESULTS: Of 260 systemic-onset JIA patients in this analysis, 151 patients received etanercept, 109 tocilizumab, 71 anakinra and 51 canakinumab. Patients with etanercept had higher clinical Juvenile Arthritis Disease Activity Score 10 scores, active joint counts and steroid use at therapy start. Serious adverse events were reported with higher frequency in patients receiving canakinumab [20/100 patient years (PY)] and tocilizumab (21/100 PY). Cytopenia and hepatic events occurred with a higher frequency with tocilizumab and canakinumab. Medically important infections were seen more often in patients with IL-6 or IL-1 inhibition. Macrophage activation syndrome occurred in all cohorts with a higher frequency in patients with canakinumab (3.2/100 PY) and tocilizumab (2.5/100 PY) vs anakinra (0.83/100 PY) and etanercept (0.5/100 PY). After adjustment only an elevated risk for infections in anakinra-treated patients remained significant. Three definite malignancies were reported in patients ever exposed to biologics. Two deaths occurred in patients treated with etanercept. CONCLUSION: Surveillance of pharmacotherapy as provided by BIKER is an import approach especially for patients on long-term treatment. Overall, tolerance was acceptable. Differences between several biologics were noted and should be considered in daily patient care.

RESUMO

BACKGROUND: Undifferentiated systemic autoinflammatory diseases (USAID) present diagnostic and therapeutic challenges. Chronic interferon (IFN) signaling and cytokine dysregulation may identify diseases with available targeted treatments. METHODS: Sixty-six consecutively-referred USAID patients underwent standardized evaluation of Type-I IFN-response-gene-signature (IRG-S); cytokine profiling, and genetic evaluation by next-generation sequencing. RESULTS: Thirty-six USAID patients (55%) had elevated IRG-S. Neutrophilic panniculitis (40% vs 0%), basal ganglia calcifications (46% vs 0%), interstitial lung disease (47% vs 5%), and myositis (60% vs 10%) were more prevalent in patients with elevated IRG-S. Moderate IRG-S elevation and highly-elevated serum IL-18 distinguished eight patients with pulmonary alveolar proteinosis (PAP) and recurrent macrophage activation syndrome (MAS). Among patients with panniculitis and progressive cytopenias, two patients were compound heterozygous for novel LRBA mutations, four patients harbored novel splice variants in IKBKG/NEMO, and six patients had de novo frameshift mutations in SAMD9L. Of additional 12 patients with elevated IRG-S and CANDLE-, SAVI- or Aicardi-Goutières-Syndrome (AGS)-like phenotypes, five patients carried mutations in either SAMHD1, TREX1, PSMB8 or PSMG2. Two patients had anti-MDA5 autoantibody-positive juvenile dermatomyositis, and seven could not be classified. Patients with LRBA, IKBKG/NEMO and SAMD9L mutations showed a pattern of IRG elevation that suggests prominent NF-κB activation different from the canonical interferonopathies CANDLE, SAVI and AGS. CONCLUSIONS: In patients with elevated IRG-S, we identified characteristic clinical features and 3 additional autoinflammatory diseases: IL-18-mediated PAP and recurrent MAS (IL-18PAP-MAS), NEMO∆5-associated autoinflammatory syndrome (NEMO-NDAS), and SAMD9L-associated autoinflammatory disease (SAMD9L-SAAD). The IRG-S expands the diagnostic armamentarium in evaluating USAIDs and points to different pathways regulating IRG expression.

RESUMO

The present guidelines are aimed at residents and board-certified physicians in the fields of dermatology, pediatrics, pediatric dermatology and pediatric rheumatology as well as policymakers and insurance funds. They were developed by dermatologists and pediatric dermatologists in collaboration with pediatric rheumatologists using a formal consensus process (S2k). The guidelines highlight topics such as disease severity, quality of life, treatment goals as well as problems associated with off-label drug therapy in children. Trigger factors and diagnostic aspects are discussed. The primary focus is on the various topical, systemic and UV-based treatment options available and includes recommendations for use and treatment algorithms. Other aspects addressed herein include vaccinations in children and adolescents with psoriasis as well as various disease subtypes such as guttate psoriasis, diaper psoriasis, pustular psoriasis and psoriatic arthritis. Finally, we also provide recommendations for imaging studies and the diagnostic workup to rule out tuberculosis prior to initiating systemic treatment. Note: This article constitutes part 2 of the Sk2 guidelines for the treatment of psoriasis in children and adolescents. Part 1 was published in last month's issue. It contained introductory remarks and addressed aspects of diagnosis and topical treatment.

RESUMO

COPA syndrome is a newly discovered hereditary immunodeficiency affecting the lung, kidneys, and joints. The mutated gene encodes the α subunit of the coatomer complex I, a protein transporter from the Golgi back to the endoplasmic reticulum. The impaired return of proteins leads to intracellular stress. The syndrome is an autoimmune and autoinflammatory disease that can be grouped among the interferonopathies. The knowledge about COPA syndrome and its treatment is still limited. In this paper, we describe an additional patient, a 15-year-old girl with rheumatoid factor-positive polyarthritis and rheumatoid nodules since the age of 2, who developed interstitial lung disease. The detected mutation c.698G>A was causing the disease. The patient presented with symmetric polyarthritis on wrists, fingers, and hip and ankle joints, with significant functional impairment, and high disease activity. Laboratory parameters demonstrated chronic inflammation, hypergammaglobulinemia, high titre ANA (antinuclear antibodies) and CCP (anti-citrullinated protein) antibodies, and rheumatoid factors. Therapies with various DMARDs (Disease Modifying Anti-Rheumatic Drugs) and biologicals failed. Upon baricitinib application, the clinical activity decreased dramatically with disappearance of joint pain and morning stiffness and significant decrease of joint swelling. A low disease activity was reached after 12 months, with complete disappearance of rheumatoid nodules. In contrast to IL-1 (interleukin-1), IL-6, and TNF (tumor necrosis factor) inhibitors, baricitinib was very successful, probably because baricitinib acts as a JAK-1/2 (janus kinase-1/2) inhibitor in the IFNα/ß (inteferone α/ß) pathway. A relatively higher dose in children is necessary. COPA syndrome represents a novel disorder of intracellular transport. Reviewing published literature on COPA syndrome, in addition to our patient, there were 31 cases further described.

RESUMO

OBJECTIVE: To evaluate safety and effectiveness of adalimumab (ADA) in polyarticular-course juvenile idiopathic arthritis (pcJIA) in the STRIVE registry (NCT00783510). METHODS: STRIVE enrolled patients with pcJIA into 2 arms based on treatment with methotrexate (MTX) alone or ADA with/without MTX (ADA±MTX). Adverse events (AEs) per 100 patient-years (PY) of observation time were analyzed by registry arm. Patients who entered the registry within 4 weeks of starting MTX or ADA±MTX, defined as new users, were evaluated for change in disease activity assessed by the C-reactive protein-based 27-joint Juvenile Arthritis Disease Activity Score (JADAS27CRP ). RESULTS: At the 7-year cut-off date (June 1, 2016), data from 838 patients were available (MTX-arm, N=301; ADA±MTX-arm, N=537). The most common AEs were nausea (10.3%), sinusitis (4.7%), and vomiting (4.3%) in the MTX-arm and arthritis (3.9%), upper respiratory tract infection (3.5%), sinusitis, tonsillitis, and injection site pain (3.0% each) in the ADA±MTX-arm. Rates of serious infection were 1.5 events/100 PY in the MTX-arm and 2.0 events/100 PY in the ADA±MTX-arm. AE and serious AE rates were similar in patients receiving ADA with versus without MTX. No deaths or malignancies were reported. New users in the ADA±MTX-arm showed a trend toward lower mean JADAS27CRP compared with new users in the MTX-arm in the first year of STRIVE. CONCLUSIONS: The STRIVE registry 7-year interim results support that ADA±MTX is well tolerated by most children. Registry median (interquartile range) ADA exposure was 2.47 (1.0-3.6) years, with 42% of patients continuing ADA at the 7-year cut-off date.

RESUMO

OBJECTIVES: To investigate the courses and outcomes of pregnancies involving JIA patients who were exposed to DMARDs. METHODS: In the Juvenile arthritis MTX/Biologics long-term Observation study, pregnant patients or male patients with pregnant partners were identified. Standardized patient interviews were conducted, and the course and outcome of pregnancy were assessed. Prospectively collected physician- and patient-reported data were also considered in the analysis. RESULTS: The study sample included 152 pregnancies in 98 women with JIA and 39 pregnancies involving 21 male patients as partners. The majority of patients had polyarticular-onset/-course JIA (61%). The average age of patients at first pregnancy was 24.1 (4.5) years, and their mean disease duration was 13.8 (5.9) years. Patients had been exposed to DMARDs for 9.5 (5.6) years, and 90% of these patients had received biologics before. Half of the pregnancies occurred during DMARD exposure, mostly with etanercept. Significant differences in pregnancy outcomes between DMARD-exposed and -unexposed pregnancies were not observed. Spontaneous abortion (13.1%) and congenital anomaly (3.6%) rates were not suggestive of increased risk compared with expected background rates. However, the rates of premature birth (12.3%) and caesarean section (37.7%) were slightly above those in the German birthing population. The disease activity of female patients remained relatively stable in pregnancy, with mean cJADAS-10 scores of 5.3, 7.1 and 5.6 in each trimester, respectively. CONCLUSION: Young adults with JIA often become pregnant or become fathers of children while still being treated with DMARDs. Data suggest no increased risk of major adverse pregnancy outcomes.

RESUMO

OBJECTIVE: To assess long-term efficacy and safety of canakinumab and the response to vaccination in children ages ≤5 years with cryopyrin-associated periodic syndrome (CAPS). METHODS: CAPS patients (ages ≤5 years) received 2 mg/kg canakinumab subcutaneously every 8 weeks; patients with neonatal-onset multisystem inflammatory disease (NOMID) received a starting dose of 4 mg/kg in this open-label trial. Efficacy was evaluated using physician global assessment of disease activity and serum levels of C-reactive protein (CRP) and amyloid A (SAA). Adverse events (AEs) were recorded. Vaccination response was evaluated using postvaccination antibody titers at 4 and 8 weeks after immunization. RESULTS: Of the 17 patients enrolled, 12 (71%) had Muckle-Wells syndrome, 4 (24%) had NOMID, and 1 (6%) had familial cold autoinflammatory syndrome. All 17 patients had a complete response to canakinumab. Disease activity improved according to the physician global assessment, and for 65% of the patients autoinflammatory disease was characterized as "absent" at the end of the study. Median CRP levels decreased over time. No such change was evident in SAA levels. During the extension study, postvaccination antibody titers increased above protective levels in 16 (94%) of 17 assessable vaccinations. Ten of the patients (59%) had AEs suspected to be related to canakinumab; 8 (47%) experienced at least 1 serious AE (SAE). None of the AEs or SAEs required interruption of canakinumab therapy. CONCLUSION: Our findings indicate that canakinumab effectively maintains efficacy through 152 weeks and appears to have no effect on the ability to produce antibodies against standard childhood non-live vaccines. The safety profile of canakinumab was consistent with previous studies, supporting long-term use of canakinumab for CAPS in children ≤5 years of age.

RESUMO

BACKGROUND: To describe the 6-year safety and efficacy of etanercept (ETN) in children with extended oligoarticular juvenile idiopathic arthritis (eoJIA), enthesitis-related arthritis (ERA), and psoriatic arthritis (PsA) METHODS: Patients who completed the 2-year, open-label, phase III CLinical Study In Pediatric Patients of Etanercept for Treatment of ERA, PsA, and Extended Oligoarthritis (CLIPPER) were allowed to enroll in its 8-year long-term extension (CLIPPER2). Children received ETN at a once-weekly dose of 0.8 mg/kg, up to a maximum dose of 50 mg/week. Efficacy assessments included the JIA core set of outcomes, the JIA American College of Rheumatology response criteria (JIA-ACR), and the Juvenile Arthritis Disease Activity Score (JADAS). Efficacy data are reported as responder analyses using a hybrid method for missing data imputation and as observed cases. Safety assessments included treatment-emergent adverse events (TEAEs). RESULTS: Out of 127 patients originally enrolled in CLIPPER, 109 (86%) entered CLIPPER2. After 6 years of trial participation (2 years in CLIPPER and 4 years in CLIPPER2), 41 (32%) patients were still taking ETN, 13 (11%) entered the treatment withdrawal phase after achieving low/inactive disease (of whom 7 had to restart ETN), 36 (28%) discontinued treatment for other reasons but are still being observed, and 37 (29%) discontinued treatment permanently. According to the hybrid imputation analysis, proportions of patients achieving JIA ACR90, JIA ACR100, and JADAS inactive disease after the initial 2 years of treatment were 58%, 48%, and 32%, respectively. After the additional 4 years, those proportions in patients who remained in the trial were 46%, 35%, and 24%. Most frequently reported TEAEs [n (%), events per 100 patient-years] were headache [28 (22%), 5.3], arthralgia [24 (19%), 4.6], and pyrexia [20 (16%), 3.8]. Number and frequency of TEAEs, excluding infections and injection site reactions, decreased over the 6-year period from 193 and 173.8, respectively, during year 1 to 37 and 61.3 during year 6. A single case of malignancy (Hodgkin's lymphoma) and no cases of active tuberculosis, demyelinating disorders, or deaths were reported. CONCLUSIONS: Open-label etanercept treatment for up to 6 years was safe, well tolerated, and effective in patients with eoJIA, ERA, and PsA. TRIAL REGISTRATION: ClinicalTrials.gov: CLIPPER, NCT00962741 , registered 20 August, 2009, CLIPPER2, NCT01421069 , registered 22 August, 2011.

RESUMO

Background: Signs and symptoms establish the diagnosis of adult onset Still's disease (AOSD) as well as of systemic onset juvenile idiopathic arthritis (sJIA). The published data regarding the importance of IL-18 as a marker for diagnosis and disease activity so far are conflicting. The aim of this study was to clarify the role of IL-18 as a diagnostic and disease activity marker in AOSD and sJIA. Methods: Thirty adult patients diagnosed with AOSD and twenty children diagnosed with sJIA were included in the study. Clinical and laboratory data were obtained retrospectively for each patient visit whenever IL-18 serum levels were determined. IL-18 levels were determined by ELISA. Sixty-five adults and twenty-three children presenting with fever and/or arthritis who did not meet the criteria for a diagnosis of AOSD or sJIA served as comparison groups. Rau's criteria and CRP values were used to evaluate disease activity. Results: IL-18 levels were significantly elevated in patients with active AOSD compared to AOSD patients in remission and to the comparison group with a median of 16,327 pg/ml, 470 pg/ml, and 368 pg/ml, respectively (p < 0.001). Analogous to AOSD in active sJIA, the median IL-18 serum level was significantly higher with 21,512 pg/ml than in the comparison group with 2580 pg/ml (p < 0.001).At our cut-off point of 5000 pg/ml, the calculated specificity of IL-18 to establish the diagnosis of AOSD was 96.9%, and the sensitivity 63.3% (AUC = 0.870, p < 0.001). For the diagnosis of sJIA, a cut-off value of 10,000 pg/ml was chosen with a specificity of 100% and a sensitivity of 60% (AUC = 0.774, p = 0.003). At a cut-off value of 5000 pg/ml, the specificity was 62% and the sensitivity 65%. Conclusions: This study gives further evidence to earlier publications of elevated IL-18 serum levels in active AOSD and sJIA, with up to 1000-fold higher concentrations compared to other rheumatic diseases. A clear association of IL-18 serum levels with disease activity in AOSD was found. The results support the use of IL-18 as an important biomarker in AOSD and sJIA.

RESUMO

OBJECTIVE: To determine whether neutropenia is associated with increased risk for infection in patients with systemic juvenile idiopathic arthritis (sJIA) and polyarticular-course juvenile idiopathic arthritis (pcJIA) treated with tocilizumab (TCZ). METHODS: Data up to Week 104 from 2 phase III trials of intravenous TCZ in sJIA (n = 112; ClinicalTrials.gov, NCT00642460) and pcJIA (n = 188; ClinicalTrials.gov, NCT00988221) were pooled. Worst common toxicity criteria grade and lowest observed absolute neutrophil count (ANC) were identified for each patient. Associations between patient characteristics and lowest observed ANC were tested using univariate regression analysis. Infection and serious infection rates per 100 patient-years (PY) in periods associated with grades 1/2 and 3/4 neutrophil counts were compared with rates associated with normal neutrophil counts. RESULTS: ANC decreased to grade ≥ 3 in 25.0% and 5.9% of sJIA and pcJIA patients, respectively, and decreases were transient. Young age (p = 0.047) and methotrexate use (p = 0.012) were positively associated with neutropenia in patients with sJIA but not in patients with pcJIA. The rate of serious infections in patients with sJIA (10.9/100 PY; 95% CI 6.8-16.5) tended to be higher than in patients with pcJIA (5.2/100 PY; 95% CI 3-8.5). No increase in rates of serious or nonserious infections was observed during periods of neutropenia in either trial. CONCLUSION: Patients with JIA treated with TCZ experienced transient neutropenia that was not associated with an increased number of infections.

RESUMO

OBJECTIVE: To study juvenile idiopathic arthritis (JIA) long-term outcomes in relation to the time of initiation of biologic disease-modifying antirheumatic drug (bDMARD). METHODS: Outcomes of JIA patients prospectively followed by the Biologika in der Kinderrheumatologie (BiKeR) and Juvenile Arthritis Methotrexate/Biologics Long-Term Observation (JuMBO) registers were analyzed with regard to drug-free remission and inactive disease, functional status and quality of life, and surgery. To analyze the influence of early bDMARD therapy on outcomes, patients were assigned to 3 groups based on the time from symptom onset to bDMARD start (G1: ≤2 years, G2: >2 to ≤5 years, and G3: >5 years). Propensity score-adjusted outcome differences were analyzed by multinomial logistic regression analyses among the groups. RESULTS: A total of 701 JIA patients were observed for mean ± SD 9.1 ± 3.7 years. At the last follow-up (disease duration mean ± SD 14.3 ± 6.1 years), 11.7% of patients were in drug-free remission, and 40.0% had inactive disease. More than half of the patients reported no functional limitation, while 5% had undergone arthroplasty, and 3% had eye surgery. At the 10-year time point, patients in G1 (n = 108) were significantly more likely to be in drug-free remission than those patients who began treatment later (G2, n = 199; G3, n = 259), with 18.5%, 10.1%, and 4.9%, respectively. Patients in G1 had significantly lower disease activity (clinical Juvenile Arthritis Disease Activity Score in 10 joints = 4.9), a better overall well-being (18.2% patient global assessment score = 0), and higher functional status (59.2% Health Assessment Questionnaire score = 0), compared to patients in G3 (7.1, 8.4%, and 43.7%, respectively). G1 patients required arthroplasty significantly less frequently than G3 patients and had significantly lower disease activity over time than patients in both G2 and G3. CONCLUSION: Early DMARD treatment is associated with better disease control and outcomes, which supports the concept of a "window of opportunity" for JIA.

RESUMO

OBJECTIVE: The objective was to evaluate the 25(OH) vitamin D (25(OH)D) status of patients with juvenile idiopathic arthritis (JIA) and determine whether the 25(OH)D level is associated with disease activity and the course of JIA. METHODS: Patients ≤ 16 years of age with recently diagnosed JIA (< 12 months) were enrolled in the inception cohort of patients with newly diagnosed JIA (ICON), an ongoing prospective observational, controlled multicenter study started in 2010. Clinical and laboratory parameters were ascertained quarterly during the first year and half-yearly thereafter. Of the 954 enrolled patients, 360 patients with two blood samples taken during the first 2 years after inclusion and with follow up of 3 years were selected. The serum 25(OH)D levels were determined and compared with those of subjects from the general population after matching for age, sex, migration status and the month of blood-drawing. RESULTS: Nearly half of the patients had a deficient 25(OH)D level (< 20 ng/ml) in the first serum sample and a quarter had a deficient level in both samples. Disease activity and the risk of developing JIA-associated uveitis were inversely correlated with the 25(OH)D level (ß = - 0.20, 95% CI - 0.37; 0.03, hazard ratio 0.95, 95% CI 0.91; 0.99, respectively). CONCLUSION: In this study, 25(OH)D deficiency was common and associated with higher disease activity and risk of developing JIA-associated uveitis. Further studies are needed to substantiate these results and determine whether correcting 25(OH)D deficiency is beneficial in JIA.

RESUMO

BACKGROUND: The availability of methotrexate and the introduction of multiple biological agents have revolutionized the treatment of juvenile idiopathic arthritis (JIA). Several international and national drug registries have been implemented to accurately monitor the long-term safety/efficacy of these agents. This report aims to present the combined data coming from Pharmachild/PRINTO registry and the national registries from Germany (BiKeR) and Sweden. METHODS: Descriptive statistics was used for demographic, clinical data, drug exposure, adverse events (AEs) and events of special interest (ESIs). For the Swedish register, AE data were not available. RESULTS: Data from a total of 15,284 patients were reported: 8274 (54%) from the Pharmachild registry and 3990 (26%) and 3020 (20%) from the German and the Swedish registries, respectively. Pharmachild children showed a younger age (median of 5.4 versus 7.6 years) at JIA onset and shorter disease duration at last available visit (5.3 versus 6.1-6.8) when compared with the other registries. The most frequent JIA category was the rheumatoid factor-negative polyarthritis (range of 24.6-29.9%). Methotrexate (61-84%) and etanercept (24%-61.8%) were the most frequently used synthetic and biologic disease-modifying anti-rheumatic drugs (DMARDs), respectively. There was a wide variability in glucocorticoid use (16.7-42.1%). Serious AEs were present in 572 (6.9%) patients in Pharmachild versus 297 (7.4%) in BiKeR. Infection and infestations were the most frequent AEs (29.4-30.1%) followed by gastrointestinal disorders (11.5-19.6%). The most frequent ESIs were infections (75.3-89%). CONCLUSIONS: This article is the first attempt to present a very large sample of data on JIA patients from different national and international registries and represents the first proposal for data merging as the most powerful tool for future analysis of safety and effectiveness of immunosuppressive therapies in JIA. REGISTRY REGISTRATION: The Pharmachild registry is registered at ClinicalTrials.gov ( NCT01399281 ) and at the European Network of Centres for Pharmacoepidemiology and Pharmacovigilance (ENCePP) ( http://www.encepp.eu/encepp/viewResource.htm?id=19362 ). The BiKeR registry is registered at ENCePP ( http://www.encepp.eu/encepp/viewResource.htm?id=20591 ).
