RESUMO
OBJECTIVES: To describe the clinical phenotype and response to treatment of autoinflammatory disease (AID) patients with the TNFRSF1A-pR92Q variant compared to patients with tumour necrosis factor receptor-associated periodic syndrome (TRAPS) due to pathogenic mutations in the same gene and patients diagnosed with other recurrent fever syndromes including periodic fever with aphthous stomatitis, pharyngitis, and adenitis (PFAPA) and syndrome of undefined recurrent fever (SURF). METHODS: Clinical data from pR92Q variant associated AID, classical TRAPS, PFAPA and SURF patients were obtained from the Eurofever registry, an international, multicentre registry enabling retrospective collection of data on AID patients. RESULTS: In this study, 361 patients were enrolled, including 77 pR92Q variant, 72 classical TRAPS, 152 PFAPA and 60 SURF patients. pR92Q carriers had an older age of disease onset than classical TRAPS and PFAPA patients. Compared to pR92Q variant patients, classical TRAPS patients had more relatives affected and were more likely to have migratory rash and AA-amyloidosis. Despite several differences in disease characteristics and symptoms between pR92Q variant and PFAPA patients, part of the pR92Q variant patients experienced PFAPA-like symptoms. pR92Q variant and SURF patients showed a comparable clinical phenotype. No major differences were observed in response to treatment between the four patient groups. Steroids were most often prescribed and effective in the majority of patients. CONCLUSIONS: Patients with AID carrying the TNFRSF1A-pR92Q variant behave more like SURF patients and differ from patients diagnosed with classical TRAPS and PFAPA in clinical phenotype. Hence, they should no longer be diagnosed as having TRAPS and management should differ accordingly.

OBJECTIVES: Differential diagnosis in children with prolonged fever is challenging. In particular, differentiating systemic-onset JIA (SJIA) from infectious diseases is difficult. Biomarkers are needed that support the diagnostic work-up. The aim of this study was to validate the usefulness of Myeloid-related protein 8/14 (MRP8/14) measurements in the diagnostic work-up of febrile children and to transfer it to clinical practice. METHODS: Data for 1110 paediatric patients were included and divided into two cohorts: (cohort A) for validation of MRP8/14 test performance with three different testing systems: the experimental ELISA, commercial ELISA and an innovative (point-of-care test) lateral flow immunoassay (LFIA); (cohort B) to validate the diagnostic accuracy with the two latter assays. RESULTS: In cohort A (n = 940), MRP8/14 was elevated in SJIA (12 110 ± 2650 ng/ml mean ± 95% CI) compared with other diagnoses (including infections and autoinflammatory diseases; 2980 ± 510 ng/ml) irrespective of fever and anti-inflammatory treatment (P < 0.001). In untreated patients with fever (n = 195) MRP8/14 levels in SJIA (19 740 ± 5080 ng/ml) were even higher compared with other diagnoses (4590 ± 1160 ng/ml) (P < 0.001, sensitivity 73%, specificity 90%). In group B1, the performance of the tests was confirmed in untreated patients with fever (n = 170): commercial ELISA (sensitivity 79%, specificity 89%) and LFIA (sensitivity 84%, specificity 81%). Compared with ferritin, IL-18, ESR, soluble IL-2 receptor and procalcitonin, MRP8/14 showed the best accuracy. CONCLUSION: MRP8/14 serum analyses have been validated as a helpful tool supporting the diagnosis of SJIA in febrile children. The results could be confirmed with commercial ELISA and LFIA enabling a rapid diagnostic point-of-care screening test.

OBJECTIVES: To evaluate the effect of canakinumab on health-related quality of life (HRQoL), work/school and social life of patients with autoinflammatory recurrent fever syndromes, including colchicine-resistant familial Mediterranean fever, mevalonate kinase deficiency, and tumour necrosis factor receptor-associated periodic syndrome, in the CLUSTER trial. METHODS: HRQoL of patients who received canakinumab 150 mg or 300 mg every four weeks in the CLUSTER trial (n=173) was assessed at baseline and Weeks 17 and 41. For children we used the Child Health Questionnaire - Parent Form 50 (CHQ-PF50), including psychosocial (PsS) and physical (PhS) component summary scores. For adults, the Short-Form-12 (SF-12) Health Survey was used, including physical (PFS) and mental (PCS) component summary scores. The Sheehan Disability Scale (SDS) was used to determine the impact of treatment on work/school, social and family life. RESULTS: The results obtained were remarkably consistent in both paediatric and adult patients across the three disease cohorts. At baseline, median scores for physical components were relatively low (26-29 for PhS and 34-38 for PFS); they improved to values similar to those expected in the general population by Week 17, and this improvement was sustained at Week 41, when median PhS scores were 47-50 and PFS 44-54. Psychosocial and mental scores also improved from baseline to Week 17 and 41, with scores comparable to the general population. Notable improvements were also observed in the SDS scale. CONCLUSIONS: Patients with three inherited autoinflammatory syndromes experienced sustained improvements on their HRQoL, work/school, and social life on treatment with canakinumab.

INTRODUCTION: Autoinflammatory diseases can cause irreversible tissue damage due to systemic inflammation. Recently, the Autoinflammatory Disease Damage Index (ADDI) was developed. The ADDI is the first instrument to quantify damage in familial Mediterranean fever, cryopyrin-associated periodic syndromes, mevalonate kinase deficiency and tumour necrosis factor receptor-associated periodic syndrome. The aim of this study was to validate this tool for its intended use in a clinical/research setting. METHODS: The ADDI was scored on paper clinical cases by at least three physicians per case, independently of each other. Face and content validity were assessed by requesting comments on the ADDI. Reliability was tested by calculating the intraclass correlation coefficient (ICC) using an 'observer-nested-within-subject' design. Construct validity was determined by correlating the ADDI score to the Physician Global Assessment (PGA) of damage and disease activity. Redundancy of individual items was determined with Cronbach's alpha. RESULTS: The ADDI was validated on a total of 110 paper clinical cases by 37 experts in autoinflammatory diseases. This yielded an ICC of 0.84 (95% CI 0.78 to 0.89). The ADDI score correlated strongly with PGA-damage (r=0.92, 95% CI 0.88 to 0.95) and was not strongly influenced by disease activity (r=0.395, 95% CI 0.21 to 0.55). After comments from disease experts, some item definitions were refined. The interitem correlation in all different categories was lower than 0.7, indicating that there was no redundancy between individual damage items. CONCLUSION: The ADDI is a reliable and valid instrument to quantify damage in individual patients and can be used to compare disease outcomes in clinical studies.

OBJECTIVES: Chronic non-bacterial osteomyelitis (CNO) or chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory disorder characterized by sterile bone osteolytic lesions. The aim of this study was to evaluate the demographic data and clinical, instrumental and therapeutic features at baseline in a large series of CNO/CRMO patients enrolled in the Eurofever registry. METHODS: A web-based registry collected retrospective data on patients affected by CRMO/CNO. Both paediatric and adult centres were involved. RESULTS: Complete baseline information on 486 patients was available (176 male, 310 female). The mean age of onset was 9.9 years. Adult onset (>18 years of age) was observed in 31 (6.3%) patients. The mean time from disease onset to final diagnosis was 1 year (range 0-15). MRI was performed at baseline in 426 patients (88%), revealing a mean number of 4.1 lesions. More frequent manifestations not directly related to bone involvement were myalgia (12%), mucocutaneous manifestations (5% acne, 5% palmoplantar pustulosis, 4% psoriasis, 3% papulopustular lesions, 2% urticarial rash) and gastrointestinal symptoms (8%). A total of 361 patients have been treated with NSAIDs, 112 with glucocorticoids, 61 with bisphosphonates, 58 with MTX, 47 with SSZ, 26 with anti-TNF and 4 with anakinra, with a variable response. CONCLUSION: This is the largest reported case series of CNO patients, showing that the range of associated clinical manifestations is rather heterogeneous. The study confirms that the disease usually presents with an early teenage onset, but it may also occur in adults, even in the absence of mucocutaneous manifestations.
RESUMO
OBJECTIVES: Autoinflammatory diseases cause systemic inflammation that can result in damage to multiple organs. A validated instrument is essential to quantify damage in individual patients and to compare disease outcomes in clinical studies. Currently, there is no such tool. Our objective was to develop a common autoinflammatory disease damage index (ADDI) for familial Mediterranean fever, cryopyrin-associated periodic syndromes, tumour necrosis factor receptor-associated periodic fever syndrome and mevalonate kinase deficiency. METHODS: We developed the ADDI by consensus building. The top 40 enrollers of patients in the Eurofever Registry and 9 experts from the Americas participated in multiple rounds of online surveys to select items and definitions. Further, 22 (parents of) patients rated damage items and suggested new items. A consensus meeting was held to refine the items and definitions, which were then formally weighted in a scoring system derived using decision-making software, known as 1000minds. RESULTS: More than 80% of the experts and patients completed the online surveys. The preliminary ADDI contains 18 items, categorised in the following eight organ systems: reproductive, renal/amyloidosis, developmental, serosal, neurological, ears, ocular and musculoskeletal damage. The categories renal/amyloidosis and neurological damage were assigned the highest number of points, serosal damage the lowest number of points. The involvement of (parents of) patients resulted in the inclusion of, for example, chronic musculoskeletal pain. CONCLUSIONS: An instrument to measure damage caused by autoinflammatory diseases is developed based on consensus building. Patients fulfilled a significant role in this process.

Objectives: The aim was to analyse factors influencing the individual colchicine dose in children with FMF, to evaluate the impact of dose adjustment on the clinical course and inflammation and to identify clinical parameters and biomarkers that predict dose increase in the near future. Methods: Data from 409 paediatric FMF patients (4566 visits) derived from the national auto-inflammatory diseases registry were analysed. Serum concentrations of S100 molecules were determined by ELISA. Results: The age-dependent colchicine dose is influenced by the present genotype. The body surface area is the anthropometric parameter that correlates best with the applied dosages. Colchicine introduction and dose increase lead to significant reduction of clinical symptoms and inflammation. During established colchicine therapy, an increase of one single biomarker increases the likelihood of a dose increment in the next 12 months with a factor of 1.62-1.94. A combination of biomarkers including S100 molecules increases this odds ratio up to 4.66 when analysing all patients and up to 7.27 when analysing patients with a high risk of severe disease. Conclusion: Colchicine therapy is currently guided mainly by the occurrence of clinical symptoms and serological inflammation. Other factors, such as the genotype, the body surface area and biomarkers, will help to manage colchicine therapy in a more individualized fashion. The additional analysis of S100 molecules as sensitive biomarkers will help to identify patients at risk for dose increases in the near future.

BACKGROUND: Hyper-IgE syndromes (HIES) are primary immunodeficiency disorders characterized by elevated serum IgE, eczema, and recurrent infections. Despite the availability of confirmatory molecular diagnosis of several distinct HIES entities, the differentiation of HIES particularly from severe forms of atopic dermatitis remains a challenge. The two most common forms of HIES are caused by mutations in the genes STAT3 and DOCK8. METHODS: Here, we assess the clinical and immunologic phenotype of DOCK8- and STAT3-HIES patients including the cell activation, proliferation, and cytokine release after stimulation. RESULTS: Existing HIES scoring systems are helpful to identify HIES patients. However, those scores may fail in infants and young children due to the age-related lack of clinical symptoms. Furthermore, our long-term observations showed a striking variation of laboratory results over time in the individual patient. Reduced memory B-cell counts in concert with low specific antibody production are the most consistent findings likely contributing to the high susceptibility to bacterial and fungal infection. In DOCK8-HIES, T-cell lymphopenia and low IFN-gamma secretion after stimulation were common, likely promoting viral infections. In contrast to STAT3-HIES, DOCK8-HIES patients showed more severe inflammation with regard to allergic manifestations, elevated activation markers (HLA-DR, CD69, CD86, and CD154), and significantly increased inflammatory cytokines (IL1-beta, IL4, IL6, and IFN-gamma). CONCLUSION: Differentiating HIES from other diseases such as atopic dermatitis early in life is essential for patients because treatment modalities differ. To expedite the diagnosis process, we propose here a diagnostic workflow.

BACKGROUND: Physical active lifestyles are essential throughout growth and maturation and may offer potential preventive and therapeutic benefit in patients with juvenile idiopathic arthritis (JIA). Insufficient physical activity (PA), in contrast, can lead to aggravation of disease-related symptoms. This study aimed to i) examine PA levels in children and adolescents with JIA compared to general population controls and ii) investigate correlates of pronounced physical inactivity in order to identify risk groups for sedentary behaviour. METHODS: Data from children and adolescents with JIA and population controls aged 3 to 17 years documented in the National Pediatric Rheumatologic Database (NPRD) and the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) were used. Self-reported PA was collected from parents/guardians of children up to 11 years of age or adolescents 12 years of age and older. To compare PA-related data, age- and sex-specific pairwise analyses were conducted considering NPRD/KiGGS participants' data from 2017. Correlates of physical inactivity among patients were identified using a linear regression model. RESULTS: Data of 6,297 matched-pairs (mean age 11.2 ± 4.2 years, female 67%, patients' disease duration 4.5 ± 3.7 years, persistent oligoarthritis 43%) were available for evaluation. Almost 36% of patients aged 3-17 years (vs. 20% of controls) achieved the WHO recommended amount of PA, while PA steadily decreased with age (18% of patients aged ≥ 12 years) and varied between JIA categories. Female adolescents and patients with enthesitis-related arthritis were least likely to achieve the minimum recommended level of PA. Physical inactivity was associated with female sex, higher age at disease onset, longer disease duration, more functional disability (C-HAQ) and higher disease activity (cJADAS-10). CONCLUSIONS: Depending on JIA category, children and adolescents with JIA were similarly or even more likely to achieve the WHO recommended minimum level of PA compared to general population controls. However, since a large proportion of young JIA patients appear to be insufficiently physically active, engagement in targeted efforts to promote PA is urgently needed.

Objectives: Animal assisted intervention is an increasingly accepted tool to improve human well-being. The present study was performed to assess whether dog assisted education has a positive effect on children suffering from rheumatic disorders with pain and adolescents with chronic pain syndrome. Design: Two groups of juvenile patients were recruited: 7-17-year-old children in children with rheumatic diseases and adolescents with chronic pain syndromes. Overall, n=26 participated in the intervention, and n=29 in the control group. Setting: The intervention group met once a month, 12 times overall, for working with man trailing dogs in various locations. Main outcome measures: The influence of dog assisted education on quality of life (PedsQLTM Scoring Algorithm), pain intensity, perception, coping (Paediatric Pain Coping Inventory-Revised), and state anxiety (State Trait Anxiety Inventory) was assessed. Results: The quality of life increased significantly in the investigated period, but for both, the intervention and the control group. The state anxiety of children was lower after the dog assisted education than before. After the dog training sessions, state anxiety was 18% to 30% lower than before the intervention. Some participants noted subjectively improved pain coping and changes in pain perception, which were not found in the data. Conclusion: Our results indicate that for children with rheumatic diseases and adolescents with chronic pain syndromes dog assisted education (1) might lead to an increase of the quality of life, (2) leads to decreased state anxiety from pre to post intervention and (3) does not influence pain perception, frequency and intensity.

OBJECTIVES: To evaluate the feasibility of the autoinflammatory disease activity index (AIDAI) as a tool to assess disease activity in patients with hereditary recurrent fever syndromes (HRFs) treated with canakinumab. METHODS: Patients with active colchicine-resistant familial Mediterranean fever (crFMF), mevalonate kinase deficiency (MKD), or tumor necrosis factor receptor-associated periodic syndrome (TRAPS) were enrolled in the phase III CLUSTER study and asked to complete the AIDAI questionnaire daily. All patients included in the analysis were treated with canakinumab, but regimens and periods of treatment varied per study protocol. The AIDAI for each patient was calculated weekly over the first 40 weeks of study, based on the diaries completed over 30 days. Disease-specific cut-off AIDAI values for inactive disease were calculated in a ROC analysis by comparing AIDAI scores with the occurrence of clinically inactive disease, based on the physician global assessments of disease activity and the occurrence of flares. RESULTS: Sixty patients with crFMF, 70 with MKD, and 43 with TRAPS were included in the analysis. Median AIDAI scores were high during the first 4 weeks for the three disease cohorts, and decreased afterwards, with some differences between disease cohorts. AIDAI values of 12.0, 9.6 and 15.5 were obtained as the most optimal thresholds to discriminate patients with inactive disease, with sensitivity and specificity values mostly over 75%. CONCLUSIONS: The AIDAI allows to discriminate between patients with active and inactive HRFs, and can be used in clinical practice to monitor the disease course of patients and the effect of medications.

AIM: To analyse the incidence, clinical presentation, laboratory and radiological findings, as well as diagnostic approaches and therapeutic procedures in paediatric patients suffering from nonbacterial osteitis. METHODS: A nationwide incidence survey was conducted from 2006 to 2008 through monthly contacts with all German paediatric and paediatric-orthopaedic hospitals. Children with osteomyelitic bone lesions newly diagnosed as suffering from nonbacterial osteitis were identified. Cases were assessed using a questionnaire to be filled in by the treating physician containing information on time since first symptoms, associated diseases, diagnostic procedures, localization of lesions, complications, laboratory and histological results, and treatment. RESULTS: Nonbacterial osteitis was newly reported in 148 children. The annual incidence was estimated at 0.4 per 100,000 children. Mean manifestation age was 11.4 years (SD 3.2); 99 children (67%) were girls. Palmoplantar pustulosis was observed in 8 (6%). Unifocal manifestations were seen in 50 (34%) patients. Of all patients with vertebral involvement (15%), 9% suffered from vertebral fractures. Bone biopsies were taken in 79 (53%) patients. CONCLUSIONS: Nonbacterial osteitis is an auto-inflammatory disorder resulting in at least 60 new paediatric cases/year in Germany. Spinal lesions and complications are frequently observed, even at first diagnosis.

BACKGROUND: Hyper-IgE syndromes (HIES) are primary immunodeficiency disorders characterized by Staphylococcus aureus abscesses, recurrent pneumonia, increased serum IgE levels, and eczema. The association of heterozygous signal transducer and activator of transcription 3 (STAT3) mutations with autosomal dominant (AD)-HIES allows the differentiation of AD-HIES from disorders associated with eczema and increased serum IgE levels, such as other primary immunodeficiencies and atopic dermatitis. OBJECTIVE: To facilitate early diagnosis of AD-HIES to initiate appropriate therapy. METHODS: The clinical phenotype (suggested by a National Institutes of Health [NIH] score of >or=40 points), STAT3 genotype, and T(H)17 cell counts were compared in a cohort of 78 patients suspected of having HIES. RESULTS: Heterozygous STAT3 missense mutations and in-frame deletions were identified in 48 patients, all but 2 with an NIH score >or=40 points. Patients with STAT3 mutations with HIES showed significantly lower T(H)17 cell counts compared with patients with wild-type STAT3 and control subjects. Only 1 patient with wild-type STAT3 had both an NIH score >or=40 points and abnormal T(H)17 cell counts (Assuntos

RESUMO
Background: Pediatric sarcoidosis is a complex inflammatory disorder with multisystemic manifestations. Kidney involvement in children is rare, and prognostic factors are unknown. Case Report and Methods: We report the case of a 16-year-old girl with multiorgan sarcoidosis and renal involvement. The patient presented with tubulointerstitial nephritis, acute kidney injury (AKI), chest CT disseminated noduli, granulomatous iridocyclitis, giant-cell sialadenitis, and arthralgia. The kidney biopsy revealed non-granulomatous interstitial nephritis. Treatment consisted of initial high-dose methylprednisolone pulse followed by oral prednisolone and methotrexate. Full remission was achieved. In addition, we performed a literature review using PubMed and analyzed data on pediatric renal sarcoidosis cases. Results: We identified 36 cases of pediatric sarcoidosis with renal involvement on presentation and data on the end-of-follow-up glomerular filtration rate (GFR). The data from the literature review showed that renal involvement was slightly more prevalent in males (60%). AKI was present in most of the described patients (84%). Oral prednisolone was used in 35 of 36 cases; in more severe cases, other immunosuppressants were used. We newly identified renal concentration impairment and granulomatous interstitial nephritis as factors with a clear trend toward GFR loss at the end of follow-up, emphasizing the importance of kidney biopsy in symptomatic patients. In contrast, higher GFR at presentation and hypercalcemia were rather favorable factors. According to the identified predictive factors, our patient has a good prognosis and is in remission. Conclusion: The factors indicating a trend toward an unfavorable renal outcome in pediatric sarcoidosis are renal concentration impairment and granulomatous interstitial nephritis at presentation, while a higher GFR is beneficial.
RESUMO
OBJECTIVE: To assess the first-year features of patients with chronic nonbacterial osteomyelitis (CNO). METHODS: Patients with a diagnosis of CNO, disease duration of under 13 months, and first registration in the German National Pediatric Rheumatologic Database (NPRD) between 2009 and 2018 were included in this cross-sectional analysis. RESULTS: Of 774 documented patients, 62.8% were female, and all patients had a median age of 11 years. The most affected clinical sites were the tibia (29.7%), pelvis (28.0%), and femur (27.8%). HLA-B27 was positive in 48 of 314 analyzed patients (15.3%). In 406 patients, an X-ray was performed at the first visit; X-ray results showed osteosclerosis/-lysis in 34.0% and hyperostosis in 14.5% of the patients. MRI scans (focal and whole-body scans) were performed in 648 patients, and 81.5% showed a positive TIRM/STIR signal. A total of 84.7% of the patients were administered nonsteroidal anti-inflammatory drugs, 9.6% were administered oral glucocorticoids, 10.8% were administered disease-modifying anti-rheumatic drugs (DMARDs), and 6.1% were administered bisphosphonates. An evaluation of the patient's questionnaire showed an overall well-being (NRS 0-10) of 2.0. The PedCNO disease "activity" score revealed a 70% improvement in variables in 43% of patients in the initial 1-year follow-up. Copresentation with diagnostic criteria of pediatric enthesitis-related arthritis was rare. CONCLUSION: To our knowledge, the NPRD cohort seemed to be the largest cohort of children and adolescents suffering from CNO worldwide. Most patients were treated effectively with NSAIDs, and only a small group of patients was administered additional medication. The patient-defined measures of disease activity had a moderate impact on patients' daily lives. TRIAL REGISTRATION: Not applicable.

BACKGROUND: TNF receptor-associated periodic syndrome (TRAPS) is a rare autoinflammatory disease caused by dominant mutation of the TNF super family receptor 1A (TNFRSF1A) gene. Data regarding long-term treatment outcomes are lacking. OBJECTIVE: To assess correlations of genotype-phenotypes in patients with TRAPS, as defined by the International Study Group for Systemic Autoinflammatory Diseases (INSAID) classification and Eurofever criteria, with treatment responses. METHODS: Data from 226 patients with variants of the TNFRSF1A gene and enrolled in the Eurofever registry were classified according to the INSAID classification in groups A (pathogenic or likely pathogenic variants), B (variants of uncertain significance or not classified variants), and C (benign or likely benign variants) and screened for Eurofever criteria. RESULTS: In group A (127 of 226 patients, 56%), all fulfilled Eurofever criteria and 20 of 127 patients (16%) developed AA amyloidosis. In group B (78 of 226 patients, 35%), 40 of 78 patients (51%) did not fulfill Eurofever criteria, displaying a lower incidence of abdominal pain (P < .02) and higher efficacy rate of on-demand nonsteroidal anti-inflammatory drugs (P < .02) and colchicine (P < .001). Group C (21 of 226 patients, 9%) presented a milder disease (P < .02) and none fulfilled Eurofever criteria. Anti-IL-1 drugs were the most frequently used in patients fulfilling Eurofever criteria, with the highest efficacy rate (>85% complete response). No patients on anti-IL-1 treatments developed AA amyloidosis, and 7 women with a history of failure to conceive had successful pregnancies. CONCLUSION: Anti-IL-1 drugs are the best maintenance treatment in patients with TRAPS. The diagnosis of TRAPS should be considered very carefully in patients of group B not fulfilling Eurofever criteria and group C, and colchicine may be preferable as the first maintenance treatment.

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.
