RESUMO
OBJECTIVES: We aimed to compare clinical spectrum and outcome between adults and children with Takayasu's arteritis (TAK) in a European population. METHODS: We made a nationwide retrospective observational study between 1988 and 2019. All adult patients met the ACR diagnostic criteria for TAK and all children met the EULAR/PRINTO/PRES criteria for paediatric TAK. RESULTS: We identified 46 children and 389 adults with TAK. The male to female ratio was 34/46 (0.74) in the paediatric group compared to 241/274 (0.88) in the adult group (P<0.05). Children presented with significantly more systemic symptoms; i.e., fever (P<0.05), fatigue (P<0.001), weight loss (P<0.001), abdominal pain (P<0.05), and myalgia (P<0.05) while adults had more upper limb claudication (P<0.01). Topography of the lesions differed significantly between the two groups: adults had more damage at the cerebral vasculature (P<0.01), upper and lower limbs (P<0.001) while children had more kidney lesions (P<0.05). Children TAK had more frequent (P<0.01) and higher (P<0.001) biological inflammation than adults. Children received higher dose-weight of corticosteroids (P=0.001) and less biotherapy (P<0.010) at diagnosis. Relapses (P<0.05) and death (8.6% vs 4.9%) were more frequent in children TAK than in adults. CONCLUSION: Paediatric TAK seems more severe than adult TAK. Therefore, paediatrics patients may require closer monitoring and systemic use of biological treatment.
RESUMO
BACKGROUND: Our study aimed to provide real-world evidence on the treatment patterns, effectiveness and safety of canakinumab in France in Familial Mediterranean Fever (FMF), Mevalonate Kinase Deficiency (MKD), and Tumor necrosis factor Receptor Associated Periodic Syndrome (TRAPS). METHODS: This study used the JIR cohort, a multicentre international registry created in 2013 to collect data on patients with juvenile inflammatory rheumatic diseases. French patients diagnosed with FMF, MKD or TRAPS and treated with canakinumab were included in this study. RESULTS: 31 FMF, 26 MKD and 7 TRAPS patients received canakinumab during the study period. Most of them initiated canakinumab at the recommended dose of 2 mg/kg or 150 mg, but less than half of FMF and MKD patients initiated it at the recommended frequency (every 4 weeks). Two years after initiation, the rate of patients still on treatment was 78.1% in FMF, 73.7% in MKD, and 85.7% in TRAPS patients. While the dose per injection remained globally the same over the course of the treatment, some adjustments of the dose intervals were observed. Six patients had a severe adverse event reported. Of those, three were possibly related to canakinumab. CONCLUSION: This interim analysis showed a good maintenance of canakinumab treatment 2 years after initiation and confirmed its safety profile in real-life practice in France in patients diagnosed with FMF, MKD and TRAPS. The high variety of dose and interval combinations observed in canakinumab treated patients let suppose that physicians adapt the posology to individual situations rather than a fixed treatment plan.

ABSTRACT: Autoimmune cytopenia (AIC) in children may be associated with positive antinuclear antibodies (ANA) and may progress to systemic lupus erythematosus (SLE). We evaluated the risk of progression to SLE of childhood-onset ANA-associated AIC. In the French national prospective OBS'CEREVANCE cohort, the long-term outcome of children with ANA-associated AIC (ANA titer ≥1/160) and a subgroup of children who developed SLE were described. ANA were positive in 355 of 1803 (20%) children with AIC. With a median follow-up of 5.8 (range, 0.1-29.6) years, 79 of 355 (22%) patients developed SLE at a median age of 14.5 (1.1-21.4) years; 20% of chronic immune thrombocytopenic purpura, 19% of autoimmune hemolytic anemia, and 45% of Evans syndrome. None of the patients with ANA-negative test developed SLE. Severe manifestations of SLE were observed in 21 patients, and 2 patients died. In multivariate analysis including patients with positive ANA within the first 3 months after AIC diagnosis, age >10 years at AIC diagnosis (relative risk [RR], 3.67; 95% confidence interval [CI], 1.18-11.4; P = .024) and ANA titer >1/160 (RR, 5.28; 95% CI, 1.20-23.17; P = .027) were associated with the occurrence of SLE after AIC diagnosis. ANA-associated AIC is a risk factor for progression to SLE, especially in children with an initial ANA titer >1/160 and an age >10 years at AIC diagnosis. ANA screening should be recommended in children with AIC, and patients with ANA should be monitored long-term for SLE, with special attention to the transition period. This trial was registered at www.ClinicalTrials.gov as #NCT05937828.

BACKGROUND: Cryopyrin-associated periodic syndrome (CAPS) is associated with NLRP3 pathogenic variants, mostly located in the NACHT (neuronal apoptosis inhibitor protein, MHC class 2 transcription activator, incompatibility locus protein from Podospora anserina, telomerase-associated protein) domain. Cold-induced urticarial rash is among the main clinical features. However, this study identified a series of 14 patients with pathogenic variants of the Y861 residue (p.Tyr861) of the LRR domain of NLRP3 and minimal prevalence of cold-induced urticarial rash. OBJECTIVES: This study aimed to address a possible genotype/phenotype correlation for patients with CAPS and to investigate at the cellular levels the impact of the Y861C substitution (p.Tyr861Cys) on NLRP3 activation. METHODS: Clinical features of 14 patients with CAPS and heterozygous substitution at position 861 in the LRR domain of NLRP3 were compared to clinical features of 48 patients with CAPS and pathogenic variants outside the LRR domain of NLRP3. IL-1ß secretion by PBMCs and purified monocytes from patients and healthy donors was evaluated following LPS and monosodium urate crystal stimulation. RESULTS: Patients with substitution at position 861 of NLRP3 demonstrated a higher prevalence of sensorineural hearing loss while being less prone to skin urticarial. In contrast to patients with classical CAPS, cells from patients with a pathogenic variant at position 861 required an activation signal to secrete IL-1ß but produced more IL-1ß during the early and late phase of secretion than cells from healthy donors. CONCLUSIONS: Pathogenic variants of Y861 of NLRP3 drive a boost-dependent oversecretion of IL-1ß associated with an atypical CAPS phenotype.

The paradigm type I interferonopathy Aicardi-Goutières syndrome (AGS) is most typically characterized by severe neurological involvement. AGS is considered an immune-mediated disease, poorly responsive to conventional immunosuppression. Premised on a chronic enhancement of type I interferon signaling, JAK1/2 inhibition has been trialed in AGS, with clear improvements in cutaneous and systemic disease manifestations. Contrastingly, treatment efficacy at the level of the neurological system has been less conclusive. Here, we report our real-word approach study of JAK1/2 inhibition in 11 patients with AGS, providing extensive assessments of clinical and radiological status; interferon signaling, including in cerebrospinal fluid (CSF); and drug concentrations in blood and CSF. Over a median follow-up of 17 months, we observed a clear benefit of JAK1/2 inhibition on certain systemic features of AGS, and reproduced results reported using the AGS neurologic severity scale. In contrast, there was no change in other scales assessing neurological status; using the caregiver scale, only patient comfort, but no other domain of everyday-life care, was improved. Serious bacterial infections occurred in 4 out of the 11 patients. Overall, our data lead us to conclude that other approaches to treatment are urgently required for the neurologic features of AGS. We suggest that earlier diagnosis and adequate central nervous system penetration likely remain the major factors determining the efficacy of therapy in preventing irreversible brain damage, implying the importance of early and rapid genetic testing and the consideration of intrathecal drug delivery.

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

MARSHALL SYNDROME. Marshall syndrome also known as PFAPA syndrome belongs to the group of autoinflammatory diseases. The acronym reflects the main clinical features of the disease: periodic fever, aphthous stomatitis, pharyngitis, and adenitis. It is the most common autoinflammatory disease, beginning between 1 and 5 years of age. There is little or no impact on growth, but the recurrence of febrile seizures can compromise the quality of life of patients. Clinical diagnosis meets positive and exclusion criteria. Putting it correctly allows a reassuring framework of care and avoids many unnecessary antibiotic treatments. Corticosteroid therapy is the reference treatment for the crisis. Tonsillectomy associated with adenoidectomy can be discussed but is not systematically recommended in this pathology, which is generally benign and most often heals spontaneously with age.
SYNDROME DE MARSHALL. Le syndrome de Marshall, aussi connu sous le nom de syndrome PFAPA, appartient au groupe des maladies auto-inflammatoires. L'acronyme reflète les principales caractéristiques cliniques de la maladie : fièvre périodique, aphtes, pharyngite, adénite. Il s'agit de la maladie auto-inflammatoire la plus fréquente, débutant entre 1 et 5 ans. Il n'y a pas ou peu de retentissement sur la croissance, mais la récurrence des accès fébriles peut obérer la qualité de vie des patients. Le diagnostic clinique répond à des critères positifs et d'exclusion. Bien poser celui-ci permet de poser un cadre de prise en charge rassurant pour l'entourage et d'éviter de nombreux traitements antibiotiques inutiles. La corticothérapie est le traitement de référence de la crise. L'amygdalectomie associée à l'adénoïdectomie peut être discutée mais n'est pas recommandée de façon systématique dans cette pathologie en général bénigne et guérissant le plus souvent spontanément avec l'âge.

The committee involved in transitional care within the French network on rare autoimmune and auto-inflammatory diseases has developed tools and published recommendations for the care during the transition of adolescents and young adults suffering from these chronic diseases which often demonstrate flares. As the challenge is the compliance to the continuation of care in the adult world, the therapeutic alliance between the young patient and his/her pediatrician and then his/her adult doctor is particularly important. The working group thus carried out a survey on how doctors and young patients perceive their relationship during the period of transition in medical supervision.
Title: Transition de la médecine pédiatrique à la médecine pour adultes dans les maladies autoimmunes et autoinflammatoires rares. Abstract: La commission « Transition ¼ de la filière de santé des maladies auto-immunes et auto-inflammatoires rares a développé des outils et émis des recommandations pour la prise en charge des adolescents et jeunes adultes atteints de ces maladies chroniques évoluant souvent par poussées, durant la période de transition de la médecine pédiatrique vers la médecine pour adultes. L'enjeu de l'adhésion du jeune patient à la poursuite de son parcours de soin dans le système de santé des adultes rend particulièrement importante l'alliance thérapeutique avec son médecin pédiatre puis son médecin pour adultes. Le groupe de travail issu de cette commission a ainsi mené une enquête sur la façon dont les médecins et les jeunes patients perçoivent leur relation durant la période de la transition du suivi médical.

Objective: The SARS-CoV-2 pandemic has induced an exceptional sanitary crisis, potentially having an impact on treatment continuation, for juvenile idiopathic arthritis (JIA) patients receiving immunosuppressive therapies. After national lockdowns, many patients were also concerned about their safety at school. We evaluated the impact of the pandemic on the optimal continuation of treatment and on the return to school in JIA patients. Methods: JIA patients under 18 years of age, usually treated with disease-modifying anti-rheumatic drugs (DMARDs) were prospectively included during their outpatient visit and completed a standardized questionnaire. The primary outcome was DMARD treatment modification in relation to the context of the pandemic but we also evaluated the pandemic's impact on the schooling. Results: One hundred and seventy three patients from 8 different expert centers were included between May and August 2020. Their mean age was 11.6 years (± 4.1 years), and most of them 31.2% (54/173) had a rheumatoid factor-negative polyarticular JIA. Fifty percent (86/172) were treated with methotrexate, and 72.5% (124/171) were treated with bDMARDs. DMARD treatment modification in relation to the pandemic was observed in 4.0% (7/173) of participants. 49.1% (81/165) of the patients did not return to school due to a personal/parental decision in 69.9% (55/81) of cases. Two patients were diagnosed positive for SARS-CoV-2 infection. Conclusion: This study suggests that JIA patients treated with DMARDs continued their treatment during the pandemic and were rarely affected by symptomatic COVID-19. In contrast, parents' reluctance was a major obstacle for returning to school. Therefore, more solidified school reopening strategies should be developed.
RESUMO
Background: Interleukin (IL)-1 inhibitors represent the main treatment in patients with colchicine-resistant/intolerant familial Mediterranean fever (crFMF), mevalonate kinase deficiency (MKD), and tumor necrosis factor receptor-associated periodic syndrome (TRAPS). However, the reasons for the use of IL-1 inhibitors in these diseases are still not completely clarified. Objective: Identify real-life situations that led to initiating anakinra or canakinumab treatment in hereditary recurrent fevers (HRFs), combining data from an international registry and an up-to-date literature review. Patients and Methods: Data were extracted from the JIRcohort, in which clinical information (demographic data, treatment, disease activity, and quality of life) on patients with FMF, MKD, and TRAPS was retrospectively collected. A literature search was conducted using Medline, EMBASE, and Cochrane databases. Results: Complete data of 93 patients with HRF (53.8% FMF, 31.2% MKD, and 15.1% TRAPS) were analyzed. Data from both the registry and the literature review confirmed that the main reasons for use of IL-1 blockers were the following: failure of previous treatment (n = 57, 61.3% and n = 964, 75.3%, respectively), persistence of disease activity with frequent attacks (n = 44, 47.3% and n = 1,023, 79.9%) and/or uncontrolled inflammatory syndrome (n = 46, 49.5% and n = 398, 31.1%), severe disease complication or associated comorbidities (n = 38, 40.9% and n = 390, 30.4%), and worsening of patients' quality of life (n = 36, 38.7% and n = 100, 7,8%). No reasons were specified for 12 (16.4%) JIRcohort patients and 154 (12%) patients in the literature. Conclusion: In the absence of standardized indications for IL-1 inhibitors in crFMF, MKD, and TRAPS, these results could serve as a basis for developing a treat-to-target strategy that would help clinicians codify the therapeutic escalation with IL-1 inhibitors.

BACKGROUND: Surgeries for idiopathic uveitis and juvenile idiopathic arthritis-associated uveitis in children are complex because of the high risk of inflammatory postoperative complications. There is no consensus about treatment adaptation during the perioperative period. The objectives of this study are to report the therapeutic changes made in France and to determine whether maintaining or stopping immunosuppressive therapies is associated with an increased risk of surgical site infection or an increased risk of uveitis or arthritis flare-up. METHODS: We conducted a retrospective cohort study between January 1, 2006 and December 31, 2018 in six large University Hospitals in France. Inclusion criteria were chronic idiopathic uveitis or chronic uveitis associated with juvenile idiopathic arthritis under immunosuppressive therapies at the time of the surgical procedure, operated before the age of 16. Data on perioperative treatments, inflammatory relapses and post-operative infections were collected. RESULTS: A total of 76 surgeries (42% cataract surgeries, 30% glaucoma surgeries and 16% posterior capsule opacification surgeries) were performed on 37 children. Adaptation protocols were different in the six hospitals. Immunosuppressive therapies were discontinued in five cases (7%) before surgery. All the children in the discontinuation group had an inflammatory relapse within 3 months after surgery compared to only 25% in the other group. There were no postoperative infections. CONCLUSIONS: The results of this study show varying practices between centres. The benefit-risk balance seems to favour maintaining immunosuppressive therapies during surgery. Further studies are needed to determine the optimal perioperative treatments required to limit post-operative inflammatory relapses.

OBJECTIVES: Therapeutic alliance (TA) is the agreement between caregiver and patient during the care process. Therapeutic adherence is a major issue for the management of Juvenile Idiopathic Arthritis (JIA) requiring child's strong ability to follow treatments. The aim of this study was to evaluate the relationship between TA and adherence in patients with JIA. METHODS: Observational, cross-sectional, multicenter study. Children, with JIA, aged 8-16, were included. Children, parents and physicians completed the Helping Alliance Questionnaire (HAQ-CP) for assessing TA. Adherence was measured using the Child/Parent Adherence Report Questionnaire (CARQ & PARQ). Demographic data, disease characteristics, current treatments and social environment were collected. The univariate relationship between TA and adherence, was studied by Pearson correlation coefficient. The multivariate analysis used a multiple linear regression model. RESULTS: A total of 119 patients were included: 68.9% girls, mean age (SD) 12.4 (2.9) years, disease duration 73.1 (48.2) months. JIA was in remission (52%), in low activity (32%) and active (16%). TA scores were high (≥80/100) for children, parents and physicians. HAQCP was highly correlated with CARQ (r=0.31; P<0.001) PARQ (r=0.37; P<0.001). In univariate analysis, disease activity (P<0.05), place of residence (P<0.01) and family status (P<0.01) were associated with child's TA. In multivariate analysis, only the place of residence (P<0.001) and the family status (P<0.05) remained associated with TA. CONCLUSION: TA strongly influences therapeutic adherence and therefore may be important for treatment effectiveness.

OBJECTIVE: The new classification criteria for the hereditary recurrent fever (HRF) syndrome [cryopyrin-associated periodic syndrome (CAPS), TNF-α receptor-associated periodic syndrome (TRAPS), FMF and mevalonate kinase deficiency] have been published recently. These criteria define two core sets of criteria for each HRF: mixed criteria, including genetic and clinical variables, and clinical criteria, relying on clinical variables only. Our aim was to validate the criteria for HRF in an independent cohort, the JIR Cohort database, an international repository of systemic inflammatory diseases. METHODS: We enrolled patients with HRF, periodic fever, adenitis, pharyngitis and aphthous stomatitis syndrome (PFAPA) and syndrome of undefined recurrent fever (SURF). A score ranging from zero to two was attributed to their respective genotypes: zero (no mutation), one (non-confirmatory genotype) or two (confirmatory genotype). The criteria were applied to all patients based on genotype scoring. The treating physician's diagnosis served as the gold standard for the determination of specificity. RESULTS: We included 455 patients. The classification criteria showed excellent specificity for CAPS and TRAPS (98% specificity each), fair specificity for FMF (88%), but poor specificity for mevalonate kinase deficiency (58%). Sub-analysis showed excellent accuracy of the mixed criteria for all four HRFs. Misclassification was mainly attributable to clinical criteria sets, with false-positive patients in all four HRF clinical criteria sets. CONCLUSION: This study represents the final validation step of the HRF classification criteria as recommended by the ACR. Genetic data appear to be necessary to classify patients with HRF correctly.

Objectives: The major role of interleukin (IL)-1 in the pathogenesis of hereditary recurrent fever syndromes favored the employment of targeted therapies modulating IL-1 signaling. However the best use of IL1 inhibitors in terms of dosage is difficult to define at present. Methods: In order to better understand the use of IL1 inhibitors in a real-life setting, our study assessed the dosage regimens of French patients with one of the four main hereditary recurrent fever syndromes (Familial Mediterranean Fever (FMF), TNF receptor associated periodic syndrome (TRAPS), cryopyrin associated periodic fever (CAPS) and mevalonate kinase deficiency). The patients were retrieved retrospectively from the JIR cohort, an international platform gathering data of patients with pediatric inflammatory diseases. Results: Forty five patients of the JIR cohort with a hereditary recurrent fever syndrome had received at least once an IL1 inhibitor (anakinra or canakinumab). Of these, 43% received a lower dosage than the one suggested in the product recommendations, regardless of the type of the IL1 inhibitor. Especially patients with FMF and TRAPS seemed to need lower treatment regimens; in our cohort none of the FMF or TRAPS patients received an intensified dose of IL-inhibitor. On-demand treatment with a short half-life IL-1 inhibitor has also been used successfully for some patients with one of these two conditions The standard dose was given to 42% of the patients; whereas an intensified dose of IL-1 inhibitors was given to 15% of the patients (44% of CAPS patients and 17% of mevalonate kinase deficiency patients). In our cohort each individual patient's need for treatment seemed highly variable, ranging from on demand treatment regimens to intensified dosage maintenance therapies depending on the activity and the severity of the underlying disease. Conclusion: IL-1 inhibitors are a good treatment option for patients with a hereditary recurrent fever syndrome, but the individual need of the dosage of IL-1 inhibitors to control the disease effectively seems highly variable. Severity, activity but also the type of the underlying disease, belong to the parameters underpinning the treat-to-target strategy implemented in an everyday life practice.
RESUMO
OBJECTIVES: The main objective of our study is to assess the infectious adverse events occurring in juvenile idiopathic arthritis (JIA) children treated with biological agents. METHODS: Patients were selected from the retrospective module of the JIRcohorte, data concerning the period between January 2001 and August 2015. All infectious adverse events (IAE) were retrieved. For every infectious side effect, the date, the severity, the need for a hospitalization, the type of pathogen and the affected organ were noted. Incidence rates were expressed in number of events per 100 person-years (100p-y), and OR were calculated. RESULTS: Six hundred seventy-seven patients with JIA were included in the study. A total of 3075.4 person-years of exposure were analyzed. One hundred eighty-four infectious events were described (6.0 events/100 p-y): 15.5/100 p-y with tocilizumab (TCZ), 9.6/100 p-y with Canakinumab (CAN), 7.4/100 p-y with abatacept (ABA), 6.9/100 p-y with Golimumab (GOL), 6.7/100 p-y with Anakinra (ANA), 6.3/100 p-y with Infliximab, 4.8/100 p-y with Etanercept, and 3.7/100 p-y with Adalimumab. Risk of developing an infection was significantly higher with IL-6 antagonists or IL-1 antagonists than with TNF-inhibitor. Forty point eight percent of the infectious adverse events (IAE) affected the upper respiratory tract or the Ear, nose and throat (ENT) system. Twelve infectious adverse events were described as severe or very severe (0.4/100p-y). No case of tuberculosis or death was reported. CONCLUSION: Infectious complications with biologics occurring in children treated for JIA are rare, and in most of the cases have a mild or moderate severity, affecting mainly the upper respiratory tract or the ENT.

Fabry disease (FD), a rare X-linked disease, can be treated with bi-monthly infusion of enzyme replacement therapy (ERT) to replace deficient α-galactosidase A (AGAL-A). ERT reduces symptoms, improves quality of life (QoL), and improves clinical signs and biochemical markers. ERT initiation in childhood could slow or stop progressive organ damage. Preventative treatment of FD from childhood is thought to avoid organ damage in later life, prompting a French expert working group to collaborate and produce recommendations for treating and monitoring children with FD. Organ involvement should be assessed by age 5 for asymptomatic boys (age 12-15 for asymptomatic girls), and immediately for children diagnosed via symptoms. The renal, cardiac, nervous and gastrointestinal systems should be assessed, as well as bone, skin, eyes, hearing, and QoL. The plasma biomarker globotriaosylsphingosine is also useful. ERT should be considered for symptomatic boys and girls with neuropathic pain, pathological albuminuria (≥3 mg/mmol creatinine), severe GI involvement and abdominal pain or cardiac involvement. ERT should be considered for asymptomatic boys from the age of 7. Organ involvement should be treated as needed. Early diagnosis and management of FD represents a promising strategy to reduce organ damage, morbidity and premature mortality in adulthood.

OBJECTIVE: Orbital mass is a rare and sight-threatening manifestation of ANCA-associated vasculitides, which remains a therapeutic challenge. We aimed to describe the presentation, therapeutic management and outcome of ANCA-associated vasculitides-related orbital mass. METHODS: We conducted a French nationwide retrospective study of patients with orbital mass in the setting of ANCA-associated vasculitides according to ACR criteria and/or Chapel Hill Consensus Conference definitions. RESULTS: Fifty-nine patients [33 women, median age 46 (range 7-90) years] were included. Fifty-six (95%) patients had granulomatosis with polyangiitis, two eosinophilic granulomatosis with polyangiitis and one microscopic polyangiitis. Orbital mass was unilateral in 47 (80%) cases, and seemed to develop from ENT involvement in most cases. Orbital mass biopsy was available in 32 (54%) patients, showing lymphoplasmacytic infiltration in 65%, fibrosis in 55%, granulomas in 48% and vasculitis in 36%. All patients but one received glucocorticoids as first-line therapy associated with immunosuppressive agents in 82%, mainly cyclophosphamide. Response to therapy was noted in 52% of patients treated with cyclophosphamide compared with 91% of those treated with rituximab. Twenty-seven (46%) patients required a second-line therapy because of relapse (59%) or refractory course (41%). Sequelae included visual impairment in 28%, with definitive blindness in 17%. Refractory course was associated with PR3-ANCA positivity, visual loss and contiguous pachymeningitis. CONCLUSION: Orbital mass is associated with refractory course and high frequency of sequelae, especially blindness. Refractory course is associated with PR3-ANCA positivity, visual loss and contiguous pachymeningitis.

BACKGROUND: Diagnosis of Periodic Fever, Aphthous stomatitis, Pharyngitis and Cervical Adenitis (PFAPA) syndrome is currently based on the modified Marshall's criteria, but no validated evidence based classification criteria for PFAPA has been established so far. METHODS: A multistep process, based on the Delphi and Nominal Group Technique was conducted. After 2 rounds of e-mail Delphi survey involving 21 experts in autoinflammation we obtained a list of variables that were discussed in an International Consensus Conference. Variables reaching the 80% of consensus between participants were included in the new classification criteria. In the second phase the new classification criteria and the modified Marshall's criteria were applied on a cohort of 80 pediatric PFAPA patients to compare their performance. RESULTS: The Delphi Survey was sent to 22 participants, 21 accepted to participate. Thirty variables were obtained from the survey and have been discussed at the Consensus Conference. Through the Nominal Group Technique we obtained a new set of classification criteria. These criteria were more restrictive in respect to the modified Marshall's criteria when applied on our cohort of patients. CONCLUSION: Our work led us to identify a new set of classification criteria for PFAPA syndrome, but they resulted to be too restrictive to be applied in daily clinical practice for the diagnosis of PFAPA.

BACKGROUND: Juvenile idiopathic arthritis (JIA) can cause structural damage. However, data on conventional radiography (CR) in JIA are scant. OBJECTIVE: To provide pragmatic guidelines on CR in each non-systemic JIA subtype. METHODS: A multidisciplinary task force of 16 French experts (rheumatologists, paediatricians, radiologists and one patient representative) formulated research questions on CR assessments in each non-systemic JIA subtype. A systematic literature review was conducted to identify studies providing detailed information on structural joint damage. Recommendations, based on the evidence found, were evaluated using two Delphi rounds and a review by an independent committee. RESULTS: 74 original articles were included. The task force developed four principles and 31 recommendations with grades ranging from B to D. The experts felt strongly that patients should be selected for CR based on the risk of structural damage, with routine CR of the hands and feet in rheumatoid factor-positive polyarticular JIA but not in oligoarticular non-extensive JIA. CONCLUSION: These first pragmatic recommendations on CR in JIA rely chiefly on expert opinion, given the dearth of scientific evidence. CR deserves to be viewed as a valuable tool in many situations in patients with JIA. KEY POINTS: ⢠CR is a valuable imaging technique in selected indications. ⢠CR is routinely recommended for peripheral joints, when damage risk is high. ⢠CR is recommended according to the damage risk, depending on JIA subtype. ⢠CR is not the first-line technique for imaging of the axial skeleton.
