RESUMO
METHODS: This study reviewed the medical records of patients from the REMICAM cohort, a multicentric longitudinal study carried out in patients with IIM, followed up between 1980 and 2014 in 12 hospitals in Madrid, Spain. Patients with definite or probable JPM, JDM, adult DM, and adult PM according to the modified Bohan and Peter criteria were selected. We compared the characteristics between JDM and JPM, and between JIIM and adult IIM. RESULTS: Eighty-six juvenile patients (75 JDMs and 11 JPMs) and 283 adult patients (133 DMs and 150 PMs) were included. Compared with patients with JDM, patients with JPM were older at diagnosis, had more fever and arthritis, and were less frequently treated with disease-modifying antirheumatic drugs (these differences were not statistically significant). Compared with patients with adult DM, those with JDM presented more frequently with calcinosis (33.8% vs 6.9%, p < 0.0001) and had less severe infections (4.3% vs 23.4%, p < 0.0001), malignancies (1.3% vs 25.6%, p < 0.0001), and mortality (3.5% vs 33%, p < 0.0001). Patients with JDM were treated less frequently with azathioprine (10.8% vs 44.7%, p < 0.0001). CONCLUSIONS: Our findings confirm that JIIMs are a heterogeneous group of diseases with relevant differences compared with adult IIMs.

OBJECTIVES: Subclinical synovitis is often detected by musculoskeletal ultrasound (MSUS) in juvenile idiopathic arthritis (JIA) patients in clinical remission. The main objective of this prospective, observational, longitudinal, multicentre study was to evaluate the predictive value of MSUS-detected subclinical synovitis in relation to flares at 12 months following TNFi tapering in a JIA population in stable clinical remission. METHODS: We included 56 JIA patients in stable remission undergoing TNFi therapy tapered at baseline and in some cases at 6 months. We performed baseline and 6-month MSUS assessment on B-mode (BM) and power Doppler (PD) mode of 22 joints and 8 tendons. RESULTS: Eighteen patients (32.1%) experienced a flare during the 12-month study period. BM synovitis was frequent (83.9%) but PD synovitis was scarcely found (8.9%). There were no significant differences in MSUS findings between patients who experienced a flare and those who remained in remission. Only 5 patients had positive for PD synovitis, in joints with BM synovitis grades 2 or 3, and none experienced a flare. Concomitant methotrexate (MTX) was more frequent in patients who were successfully tapered (71.1% vs. 27.8%; p=0.002) and patients older than 12 experienced a greater number of flares and earlier onset. CONCLUSIONS: Subclinical synovitis, as detected by MSUS, proved not to be a predictor of flares. Those patients on a TNFi-tapered concomitant methotrexate regimen experienced the fewest flares although flare risk increased with age.

We report two unrelated infants in whom chronic urticaria was the first clinical manifestation of cryopyrin-associated periodic syndrome, which should be suspected in infants with early-onset chronic urticaria, especially if there is a neutrophil-rich infiltrate in the skin biopsy. Early diagnosis of cryopyrin-associated periodic syndrome may lead to early and successful treatment with anti-interleukin-1 medications.

The present study was undertaken to assess mortality, causes of death, and associated prognostic factors in a large cohort of patients diagnosed with idiopathic inflammatory myositis (IIM) from Spain. A retrospective longitudinal study was carried out in 467 consecutive patients with IIM, identified from 12 medical centers. Patients were classified as primary polymyositis, primary dermatomyositis (DM), overlap myositis, cancer-associated myositis (CAM), and juvenile idiopathic inflammatory myopathies. A total of 113 deaths occurred (24%) after a median follow-up time of 9.7 years. In the overall cohort, the 2-, 5-, and 10-year survival probabilities were 91.9, 86.7, and 77%, respectively. Main causes of death were infections and cancer (24% each). Multivariate model revealed that CAM (HR = 24.06), OM (HR = 12.00), DM (HR = 7.26), higher age at diagnosis (HR = 1.02), severe infections (HR = 3.66), interstitial lung disease (HR = 1.61), and baseline elevation of acute phase reactants (HR = 3.03) were associated with a worse prognosis, while edema of the hands (HR = 0.39), female gender (HR = 0.39), and longer disease duration (HR = 0.73) were associated with a better prognosis. The standardized mortality ratio was 1.56 (95% CI 1.28-1.87) compared to the Spanish general population. Our findings indicate that IIM has a high long-term mortality, with an excess of mortality compared to the Spanish population. A more aggressive therapy may be required in IIM patients presenting with poor predictive factors.

To develop recommendations on the transition from pediatric care to adult care in patients with chronic inflammatory rheumatic diseases with childhood onset based. Recommendations were generated following nominal group methodology and Delphi technique. A panel of 16 experts was established. A systematic literature review (on transitional care) and a narrative review were performed and presented to the panel in the first panel meeting to be discussed. A first draft of recommendations was generated and circulated. Focal groups with adolescents, young adults and parents were organized. In a second meeting, the focus group results along with the input from invited psychologist were used to establish definitive recommendations. Then, a Delphi process (two rounds) was carried out. A group of 72 pediatric and adult rheumatologists took part. Recommendations were voted from 1 (total disagreement) to 10 (total agreement). We defined agreement if at least 70 % voted ≥7. The level of evidence and grade or recommendation was assessed using the Oxford center for evidence-based medicine levels of evidence. Transition care was defined as a purposeful, planned process that addresses the medical, psychosocial and educational/vocational needs of adolescents and young adults with chronic inflammatory rheumatic diseases with childhood onset as they move from child-centered to adult-oriented healthcare systems. The consensus covers: transition needs, barriers and facilitators, transitional issues (objectives, participants, content, phases, timing, plans, documentation and responsibilities), physicians' and other health professionals' knowledge and skill requirements, models/programs, and strategies and guideline for implementation. Preliminary recommendations and agreement grade are shown in the Table (first Delphi round). These recommendations are intended to provide health professionals, patients, families and other stakeholders with a consensus on the transition process from pediatric to adult care.

OBJECTIVES: To determine the prevalence of abnormalities detected by ultrasonography (US) in children with juvenile idiopathic arthritis (JIA) showing clinically inactive disease (ID) on medication and off medication. INCLUSION CRITERIA: 1) JIA patients, 2) clinician-determined ID, 3) JIA drugs withdrawal or stably dosed modified anti-rheumatic drugs (DMARDs) therapy for at least 6 months prior to inclusion, 4) biologics naïve patients. Clinical and US assessments were performed on 44 joints, which were scored for grey-scale (GS) synovitis and Power Doppler (PD) signal. PD signal inside intra-articular synovium or tendon sheath was considered as inflammatory activity. RESULTS: Thirty-four patients were included, of whom 23 patients were labelled as ID on medication and 11 patients without medication. The duration of the current episode of ID at the inclusion time was 9.5 months. Although it was longer for the group off medication there was no significant difference between the two groups (p=0.06). Thirteen patients presented US findings. Number of US-detected synovial abnormalities was higher in patients on medication, but there were no significant differences between both groups in the detection of GS synovitis (p=0.86), GS tenosynovitis (p=0.78) and PD signal (p=0.38). Out of 37 joints presenting US-determined GS-synovitis, 18 joints showed PD signal. CONCLUSIONS: Our study provides evidence of synovitis and tenosynovitis on B-mode US in JIA patients with clinical inactivity. In addition, inflammatory activity upheld by power-Doppler has been shown in a few joints from patients on medication.

OBJECTIVE: To characterize and describe clinical experience with childhood-onset non-infectious uveitis. STUDY DESIGN: A multicenter retrospective multidisciplinary national web-based registry of 507 patients from 21 hospitals was analyzed. Cases were grouped as immune disease-associated (IMDu), idiopathic (IDIu) or ophthalmologically distinct. Characteristics of juvenile idiopathic arthritis-associated (non-HLA-B27-related) uveitis (JIAu), IDIu, and pars planitis (PP) were compared. RESULTS: IMDu (62.3%) and JIAu (51.9%) predominated in young females; and IDIu (22.7%) and PP (13.6%) in older children, without sex imbalance. Ocular complications occurred in 45.3% of cases (posterior synechiae [28%], cataracts [16%], band keratopathy [14%], ocular hypertension [11%] and cystoid macular edema [10%]) and were associated with synthetic (86%) and biologic (65%) disease-modifying antirheumatic drug (DMARD) use. Subgroups were significantly associated (p < 0.05) with different characteristics. JIAu was typically anterior (98%), insidious (75%), in ANA-positive (69%), young females (82%) with fewer complications (31%), better visual outcomes, and later use of uveitis-effective biologics. In contrast, IDIu was characteristically anterior (87%) or panuveitic (12.1%), with acute onset (60%) and more complications at onset (59%: synechiae [31%] and cataracts [9.6%]) and less DMARD use, while PP is intermediate, and was mostly bilateral (72.5%), persistent (86.5%) and chronic (86.8%), with more complications (70%; mainly posterior segment and cataracts at last visit), impaired visual acuity at onset, and greater systemic (81.2%), subtenon (29.1%) and intravitreal (10.1%) steroid use. CONCLUSION: Prognosis of childhood uveitis has improved in the "biologic era," particularly in JIAu. Early referral and DMARD therapy may reduce steroid use and improve outcomes, especially in PP and IDIu.
RESUMO
OBJECTIVE: The goal of juvenile idiopathic arthritis (JIA) treatment is to maintain clinical remission. It is also important to reduce drug exposure, whenever possible, in order to avoid or decrease potential side effects. We aimed to analyze remission survival after systemic treatment withdrawal and to determine which factors can influence it. METHODS: We conducted a multicenter, observational, longitudinal study. All patients included had a diagnosis of JIA. We analyzed remission survival using Kaplan-Meier curves according to the systemic treatment received (methotrexate [MTX] alone or in combination with biologic disease-modifying antirheumatic drugs [bDMARDs]) and JIA subgroups (oligoarticular and polyarticular course, juvenile spondyloarthritis, and systemic JIA). In addition, risk factors were examined using multivariate analysis. RESULTS: We included 404 patients with JIA; 370 of them (92%) had received systemic treatment at some point and half of them (185 patients) had withdrawn on at least 1 occasion. There were 110 patients who flared (59%) with a median time of 2.3 years. There were no differences in remission survival between JIA subcategories. Twenty-nine percent of patients with JIA who received MTX and bDMARDs, in which MTX alone was withdrawn, flared; median time to flare of 6.3 years. However, if only the bDMARD was withdrawn, flares occurred 57% of the time; median time to flare of 1.1 years. CONCLUSION: Flares are frequent when systemic treatment is withdrawn, and uveitis or joint injections could be related risk factors. In MTX and biologic-naïve patients, the frequency of flares occurred in more than half of patients, although they were less frequent when clinical remission lasted for > 1 year.

Systemic juvenile idiopathic arthritis (sJIA) is a chronic childhood inflammatory disease. SJIA accounts for approximately 5-15 per cent of all cases of JIA and has a high morbidity and mortality rate. In this disease, pulmonary complications (PC) other than pleuritis are much less frequent and not easily recognised by clinicians. Pulmonary hypertension, the most severe PC, is associated with uncontrolled disease and use of biologic therapies. We present a case of a school-age female with sJIA who died of acute cardiopulmonary instability secondary to pulmonary venous-occlusive disease demonstrated by necropsy. We describe her clinical evolution. We also undertook a narrative review of the literature about PC in sJIA to discuss the current state of the art regarding this complication. High disease activity and the use of multiple therapies include disease-modifying anti-rheumatic drugs should be a red flag for clinicians when discounting PC and pulmonary hypertension. The combination of chest X-ray, electrocardiogram and echocardiogram appear to be the best tests to achieve an early diagnosis.

OBJECTIVES: To describe the methodology, objectives, and initial data of the registry of young adult patients diagnosed with Juvenile Idiopathic Arthritis (JIA), JUVENSER. The main objective of the project is to know the sociodemographic and clinical characteristics, and disease activity of patients with JIA reaching the transition to adulthood. MATERIAL AND METHOD: Longitudinal, prospective, multicentre study, including patients between 16 and 25 years old, with a diagnosis of JIA in any of its categories. The main objective is to determine the characteristics and activity of JIA in the young adult. It includes sociodemographic variables, clinical variables, disease activity and joint damage rates, data on the use of health resources, and treatments used. The total duration of the project will be 3 years. A cohort of 534 young adult patients was obtained. CONCLUSIONS: The JUVENSER registry will constitute a cohort of young adults with JIA, which will allow the evaluation of the clinical characteristics and response to treatment of patients with disease onset in childhood, moving to adult clinics.

OBJECTIVE: Chronic infantile neurologic, cutaneous, articular syndrome (CINCA), also known as neonatal-onset multisystem inflammatory disease (NOMID), is a severe, early-onset autoinflammatory disease characterized by an urticaria-like rash, arthritis/arthropathy, variable neurologic involvement, and dysmorphic features, which usually respond to interleukin-1 blockade. CINCA/NOMID has been associated with dominant Mendelian inherited NLRP3 mutations. However, conventional sequencing analyses detect true disease-causing mutations in only approximately 55-60% of patients, which suggests the presence of genetic heterogeneity. We undertook the current study to assess the presence of somatic, nongermline NLRP3 mutations in a sporadic case of CINCA/NOMID. METHODS: Clinical data, laboratory results, and information on treatment outcomes were gathered through direct interviews. Exhaustive genetic studies, including Sanger method sequencing, subcloning, restriction fragment length polymorphism assay, and pyrosequencing, were performed. RESULTS: The patient's CINCA/NOMID was diagnosed based on clinical features (early onset of the disease, urticaria-like rash, knee arthropathy, and dysmorphic features). The patient has exhibited a successful response to anakinra within the last 28 months. Analysis of NLRP3 identified a novel heterozygous variant (p.D303H) that was detected in approximately 30-38% of circulating leukocytes. The absence of this variant in healthy controls and in the patient's parents suggested a de novo true disease-causing mutation. Additional analyses showed that this novel mutation was present in both leukocyte subpopulations and epithelial cells. CONCLUSION: Our findings identify the novel p.D303H NLRP3 variant in a Spanish patient with CINCA/NOMID as a new disease-causing mutation, which was detected as a somatic, nongermline mutation in hematopoietic and nonhematopoietic cell lineages. Our data provide new insight into the role of low-level mosaicism in NLRP3 as the pathophysiologic mechanism underlying cryopyrin-associated periodic syndrome.

The role of patient adherence in improving the efficacy of any treatment is widely accepted, as well as its impact in optimizing the use of healthcare resources and associated costs. Adherence is particularly affected in chronic conditions, such as rheumatoid arthritis (RA), requiring long-term therapies and a commitment of the patient to manage his/her disease. Methotrexate (MTX) is one of the mainstays of treatment for several immune-mediated inflammatory joint and skin diseases, especially RA. The use of parenteral MTX, particularly when administered as a subcutaneous (SC) injection, has recently raised a great interest to overcome the limitations of oral MTX. For addressing this issue, new optimized self-injection systems have been developed to improve the ease of use of SC MTX. Increasing evidence shows how patients tend to opt for autoinjectors over prefilled syringes or conventional syringes in terms of easiness of use, preference and satisfaction, regardless of whether the treatment is a biologic or MTX. Additionally, positive views and beliefs of patients about treatment may contribute to increasing expectations of effectiveness and treatment adherence. Similarly, the implementation of prefilled pens in clinical practice might be a way to facilitate and simplify the self-injection of SC MTX delivery, optimizing adherence and treatment outcomes as a consequence. This article aimed to review the available literature data on the use of MTX autoinjectors and their impact on treatment adherence and patients' perceptions.
RESUMO
INTRODUCTION: Lupus nephritis is an early manifestation in the development of systemic lupus erythematosus that worsens the morbidity and mortality of these patients. OBJECTIVE: To study the form of presentation in patients with lupus nephritis, the clinical and immunological characteristics, and their relationship with renal histology. PATIENTS AND METHOD: Retrospective study in children under 18 years of age, with lupus nephritis, in follow-up in a third level children's hospital in Madrid, between January 2012 and May 2020. We recorded demographic, clinical, and laboratory data (blood count, renal function, liver function, protein, ionogram, blood glucose, uric acid, lactate dehydrogenase, coagulation, and urine analysis), as well as immunological data (immunoglobulins, antinuclear antibodies, comple ment, and lupus anticoagulant), and histological classification data. Descriptive analysis and analysis of associations between variables was performed, with a significant p < 0.05. RESULTS: 16 patients (11 women) were included, the median age at presentation was 10.6 ± 2.3 years (5.7-15.3). The median time between symptoms onset and renal involvement was 6.3 months ± 10.5 (range 0 - 33.6). Renal involvement was the initial manifestation in 37.5% of patients. 50% had arthralgias or arthritis prior to diagnosis, and 25% had fever and constitutional symptoms (asthenia, anorexia, and/or weight loss). The most frequent form of renal involvement was microhematuria associated with proteinuria in non-nephrotic range. In the renal anatomo-pathological study, according to the ISN/RPS 2003 classification, grades III (46.6%) and IV (33.3%) predominated. CONCLUSIONS: Six patients presented renal involvement at baseline with musculoskeletal involvement being more frequent. Most patients (86.6%) presented advanced lupus nephritis in the histological study at diagnosis. Immunologic in volvement was the only marker that correlated with systemic involvement.

BACKGROUND: This study aimed to assess the baseline characteristics and clinical outcomes of coronavirus disease 2019 (COVID-19) in pediatric patients with rheumatic and musculoskeletal diseases (RMD) and identify the risk factors associated with symptomatic or severe disease defined as hospital admission, intensive care admission or death. METHODS: An observational longitudinal study was conducted during the first year of the SARS-CoV-2 pandemic (March 2020-March 2021). All pediatric patients attended at the rheumatology outpatient clinics of six tertiary referral hospitals in Madrid, Spain, with a diagnosis of RMD and COVID-19 were included. Main outcomes were symptomatic disease and hospital admission. The covariates were sociodemographic and clinical characteristics and treatment regimens. We ran a multivariable logistic regression model to assess associated factors for outcomes. RESULTS: The study population included 77 pediatric patients. Mean age was 11.88 (4.04) years Of these, 30 patients (38.96%) were asymptomatic, 41 (53.25%) had a mild-moderate COVID-19 and 6 patients (7.79%) required hospital admission. The median length of hospital admission was 5 (2-20) days, one patient required intensive care and there were no deaths. Previous comorbidities increased the risk for symptomatic disease and hospital admission. Compared with outpatients, the factor independently associated with hospital admission was previous use of glucocorticoids (OR 3.51; p = 0.00). No statistically significant risk factors for symptomatic COVID-19 were found in the final model. CONCLUSION: No differences in COVID-19 outcomes according to childhood-onset rheumatic disease types were found. Results suggest that associated comorbidities and treatment with glucocorticoids increase the risk of hospital admission.

Several syndromes manifest as recurrent daily fevers, skin lesions, and multisystem inflammation. We describe 4 patients with early-onset recurrent fevers, annular violaceous plaques, persistent violaceous eyelid swelling, low weight and height, lipodystrophy, hepatomegaly, and a range of visceral inflammatory manifestations. Laboratory abnormalities included chronic anemia, elevated acute-phase reactants, and raised liver enzymes. Histopathologic examination of lesional skin showed atypical mononuclear infiltrates of myeloid lineage and mature neutrophils. Our patients have a distinctive early-onset, chronic inflammatory condition with atypical or immature myeloid infiltrates in the skin. We propose the acronym CANDLE (chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature) syndrome for this newly described disorder, which is probably genetic in origin.

BACKGROUND: Inflammatory idiopathic myositis (IIM) comprises a heterogeneous group of systemic muscular diseases that can occur together with other connective tissue diseases (CTD), named overlap myositis (OM). The question of whether OM is a distinct entity still remains controversial. AIM: The present study was conducted to assess the clinical and prognostic differences between patients diagnosed with OM, primary polymyositis (PM) and primary dermatomyositis (DM). METHOD: The study consists of a retrospective longitudinal and multicenter series of IIM patients. Patients were classified as OM, PM and DM. Overlap myositis was defined as patients fulfilling criteria for IIM plus criteria for other CTD (namely systemic sclerosis, systemic lupus erythematosus, mixed connective tissue disease, rheumatoid arthritis and primary Sjögren's syndrome). RESULT: A total of 342 patients were included (98 OM, 137 PM and 107 DM). Overlap myositis patients, in comparison with PM and DM, showed significant differences, with more extramuscular involvement, particularly more arthritis (66%, 34.6% and 48.1%, respectively), puffy fingers (49.5%, 11.1% and 24.3%), sclerodactyly (45.4%, 2.2% and 2%), dysphagia (41.8%, 18.2% and 26.4%), Raynaud phenomenon (65.3%, 16.9% and 19.8%), leucopenia (28.9%, 2.2% and 8.4%), thrombocytopenia (8.2%, 2.2% and 1.9%), interstitial lung disease (ILD) (48%, 35% and 30.8%), renal manifestations (13.4%, 3.7% and 1.9%), and more severe infections (41.3%, 26.7% and 21%). No significant differences were found in survival between groups in log rank test (P = 0.106). Multivariate adjusted survival analyses revealed a worse prognosis for severe infections, ILD and baseline elevation of acute phase reactants. CONCLUSION: Overlap myositis stands out as a distinct entity as compared to PM and DM, featuring more extramuscular involvement and more severe infections. Close monitoring is recommended in this subset for early detection and treatment of possible complications.

OBJECTIVE: To study prognostic factors in different types of idiopathic inflammatory myopathies (IIM) associated with interstitial lung disease (ILD). PATIENTS AND METHODS: Multicenter retrospective study of a Spanish cohort of patients diagnosed with IIM. Patients were classified into four categories: polymyositis (PM), dermatomyositis (DM), antisynthetase syndrome (ASS), and overlap myositis (OM). Sociodemographic data, clinical characteristics, antibodies, and treatments were collected. Cox regression models were calculated to identify factors associated with mortality, the necessity for long-term oxygen therapy (LTOT), and deterioration in respiratory function tests (RFT). RESULTS: The number of patients included was 478, of whom 112 (23.4%) suffered from ILD: 17% PM, 16% DM, 45% ASS, and 22% OM. Factors associated with mortality in the multivariate analysis were clinically meaningful progression of ILD after 3 months (CMP 3m) (hazard ratio (HR) 9.48, p = 0.005), severe infections (HR 6.41, p = 0.016), heliotrope erythema (HR 31.1, p = 0.002), delay in diagnosis (HR 1.29; p = 0.011), and Raynaud's phenomenon (HR 11.9, p = 0.007). However, being female (HR 0.19, p = 0.044) and positivity solely for ANAs (HR 0.08, p = 0.008) presented a protective effect. CMP 3m (HR 22.7, p = 0.027) was associated with the need for LTOT, while basal aldolase (HR 0.90; p = 0.049) had a protective effect. Likewise, joint manifestations (HR 0.04, p = 0.034) were shown to reduce risk of deterioration in RFT. CONCLUSIONS: CMP 3m, severe infections, delay in diagnosis, heliotrope erythema, and Raynaud's phenomenon were identified as factors of poor prognosis in different IIM associated with ILD.

OBJECTIVE: To analyze clinical characteristics, survival and causes of death of patients diagnosed with autoimmune inflammatory myositis in the REMICAM registry from the Society of Rheumatology in the Community of Madrid (SORCOM). METHODS: Multicenter cohort of patients diagnosed with autoimmune inflammatory myopathy with follow-up between January 1980 and December 2014. A total of 313 variables concerning demographic, clinical and morbidity data were collected, and a comparison was performed between clinical subgroups. RESULTS: A total of 479 patients were recruited from 12 centers, with 14% of patients lost to follow-up. Seventy-four percent of cases were women, age at diagnosis of 44±23 years and a mean follow-up period of 10±8 years. The most frequent clinical subgroups were primary myositis (PM 29%, DM 22%), followed by overlap myositis (20.5%), juvenile myositis (18%), myositis associated with cancer (8%), immune-mediated necrotizing myositis (1%) and inclusion body myositis (1%). During the follow-up period, a total of 114 deaths (28%) were registered, the main causes being cancer (24%), infections (23%) and cardiovascular events (21%). CONCLUSIONS: A total of 479 patients were recruited in the REMICAM registry of inflammatory myopathies. Including sociodemographic, clinical and prognostic information, it represents the largest Spanish multicenter registry to date in rheumatology, and constitutes an important source for conducting further substudies.
