RESUMO
ABSTRACT Objective: To describe the clinical features and outcomes of patients with uveitis associated with juvenile idiopathic arthritis (JIA) and idiopathic uveitis. Methods: This was an observational, retrospective study, conducted in a tertiary center. Patients under 18 years old who experienced at least one episode of uveitis and followed between 2000 and 2019 were included. Results: A total of 82 patients were included, of whom 43 had idiopathic uveitis and 39 had uveitis associated with JIA. Anterior uveitis was the primary site of ocular inflammation (76.8%) and occurred in 24 and 39 patients with idiopathic uveitis and uveitis associated with JIA arthritis, respectively (p=0.02). The complete response to corticotherapy was more frequent in uveitis associated with JIA (p=0.001). Total and partial responses to biological disease modifying antirheumatic drugs were more frequent in uveitis associated with JIA (p=0.025) and idiopathic uveitis (p=0.045), respectively. There were 203 complications: cataracts were more frequently present in idiopathic uveitis (p=0.05), while synechiae was more frequent in uveitis associated with JIA (p=0.02). Conclusion: Idiopathic uveitis and uveitis associated JIA frequently follow a chronic course and an increased risk of visual loss in childhood. The uveitis associated with JIA showed better response to systemic corticotherapy and total response to biologic disease modifying antirheumatic drugs more frequently.
RESUMO Objetivos: Descrever as características clínicas e desfechos dos pacientes com uveíte associada à Artrite Idiopática Juvenil (AIJ) e da Uveíte Idiopática. Métodos: Este foi um estudo retrospectivo observacional conduzido em um centro terciário. Foram incluídos pacientes abaixo dos 18 anos de idade que apresentaram pelo menos um episódio de uveíte e que estiveram em acompanhamento médico entre os anos de 2000 e 2019. Resultados: Foram incluídos 82 pacientes, sendo 43 com uveíte idiopática e 39 com uveíte associada à AIJ. A uveíte anterior foi o sítio primário de acometimento (76,8%) em 24 e 39 pacientes com uveíte idiopática e uveíte associada à AIJ, respectivamente (p=0.02). Resposta total à corticoterapia foi mais frequente na uveíte associada à AIJ (p=0.001). Respostas total e parcial às drogas antirreumáticas modificadoras de doença biológicas foram mais frequentes na uveíte associada à AIJ (p=0.025) e na uveíte idiopática (p=0.045), respectivamente. Foram encontradas 203 complicações: a catarata foi mais frequente na uveíte idiopática (p=0.05), enquanto a sinéquia foi mais frequente na uveíte associada à AIJ (p=0.02). Conclusão: A uveíte idiopática e a uveíte associada à AIJ frequentemente apresentam um curso crônico e um risco elevado de perda visual na infância. A uveíte associada à AIJ apresentou melhor resposta à corticoterapia sistêmica e resposta total às drogas modificadoras de doença reumática biológicas mais frequentemente.
RESUMO
BACKGROUND: Concerns about the safety and efficacy of vaccines in patients with autoimmune diseases (AID) have led to contradictions and low vaccination coverage in this population, who are at a higher risk of infections, including by human papillomavirus (HPV). Although HPV vaccines have been recommended for immunocompromised patients, there is still a lack of data to support its use for AID patients, such as juvenile dermatomyositis (JDM) patients. The aim of this study was to assess the safety and immunogenicity of the quadrivalent HPV (qHPV) vaccine in a cohort of JDM patients. METHODS: JDM patients aged from 9 to 20 years and healthy controls (HC) were enrolled to receive a 3-dose schedule of qHPV vaccine from March/2014 to March/2016. Study visits were performed before the first dose, 1 month after the second and third doses, and 6 months after the third dose. Participants completed a diary of possible adverse events for 14 days following each dose of vaccination (AEFV). Disease activity and current therapy were analyzed at each visit for JDM patients. In addition, serum samples from all participants were collected to test antibody concentrations against HPV16 and 18 at each visit. Participant recruitment was conducted in ten Brazilian centres. From 47 eligible JDM patients and 41 HC, 42 and 35, respectively, completed the 3-dose schedule of the vaccine, given that five JDM patients and two HC had received doses prior to their inclusion in the study. RESULTS: The AEFVs presented by the participants were mild and in general did not differ between JDM and HC groups. No severe AEFVs were related to the vaccination. Disease activity was stable, or even improved during the follow-up. One month after the third dose of the vaccine the JDM group presented seropositivity of 100% for HPV16 and 97% for HPV18, similarly to the HC group, who presented 100% for both serotypes (p = 1.000). Six months after the third dose the seropositivity for the patient group was 94% for both HPV types. CONCLUSIONS: The HPV vaccination in this cohort of JDM patients was safe and immunogenic. Since the seropositivity against HPV16 and 18 was very high after the 3-dose schedule, this regimen should be recommended for JDM patients. TRIAL REGISTRATION: Brazilian Clinical Trials Registry, number: RBR-9ypbtf . Registered 20 March 2018 - Retrospectively registered.

BACKGROUND: To our knowledge there are no studies assessing anti-Ro/SSA and anti-La/SSB autoantibodies in a large population of childhood-systemic lupus erythematosus (cSLE) patients. METHODS: This was a retrospective multicenter cohort study performed in 10 Pediatric Rheumatology services, São Paulo state, Brazil. Anti-Ro/SSA and anti-La/SSB antibodies were measured by enzyme linked immunosorbent assay (ELISA) in 645 cSLE patients. RESULTS: Anti-Ro/SSA and anti-La/SSB antibodies were evidenced in 209/645 (32%) and 102/645 (16%) of cSLE patients, respectively. Analysis of cSLE patients with and without anti-Ro/SSA antibodies revealed higher frequencies of malar rash (79% vs. 71%, p=0.032), photosensitivity (73% vs. 65%, p=0.035), cutaneous vasculitis (43% vs. 35%, p=0.046) and musculoskeletal involvement (82% vs. 75%, p=0.046) in spite of long and comparable disease duration in both groups (4.25 vs. 4.58years, p=0.973). Secondary Sjögren syndrome was observed in only five patients with this antibody (2.5% vs. 0%, p=0.0035), two of them with concomitant anti-La/SSB. The presence of associated autoantibodies: anti-Sm (50% vs. 30%, p<0.0001), anti-RNP (39% vs. 21%, p<0.0001) and anti-ribossomal P protein (46% vs. 21%, p=0.002) was also significantly higher in patients with anti-Ro/SAA antibodies. Further evaluation of cSLE patients with the presence of anti-La/SSB antibodies compared to those without these autoantibodies showed that the frequency of alopecia (70% vs. 51%, p=0.0005), anti-Sm (59% vs. 31%, p<0.0001) and anti-RNP (42% vs. 23%, p<0.0001) were significantly higher in the former group. CONCLUSIONS: Our large multicenter cohort study provided novel evidence in cSLE that anti-Ro/SSA and/or anti-La/SSB antibodies were associated with mild manifestations, particularly cutaneous and musculoskeletal. Secondary Sjögren syndrome was rarely observed in these patients, in spite of comparable frequencies of anti-Ro/SSA and/or anti-La/SSB reported for adult SLE.

OBJECTIVE: To assess aerobic capacity and cardiac autonomic modulation in juvenile fibromyalgia syndrome (JFM) patients at diagnosis in response to graded exercise text. METHODS: A multicenter cross-sectional study included 25 JFM patients and 25 healthy controls. Both groups participated only in physical education classes at school. A treadmill graded cardiorespiratory test was performed and the heart-rate (HR) response during exercise was evaluated by the chronotropic reserve (CR). Pain, functional ability, and health-related quality of life (HRQL) were assessed. RESULTS: The median current age was similar in JFM and controls (15 vs. 15 years, p = 0.890), as well as body mass index (p = 0.332), female gender (p = 1.000), and Tanner stages (p = 0.822). The medians of HRQL parameters (total score/physical health/psychosocial health) were significantly lower in JFM vs. controls according to patient and parent self-reports (p < 0.001). The median of peak HR [181 (150-198) vs. 197 (181-202)bpm, p < 0.001], chronotropic reserve [84 (53-98) vs. 99 (84-103)%, p < 0.001], and resting to peak [96 (65-181) vs. 127 (61-185)bpm, p = 0.010] were significantly lower in JFM compared to controls. The median of ΔHRR1 [15 (3-39) vs. 35 (9-52)bpm, p < 0.001], ΔHRR2 [37 (20-57) vs. 51 (32-94)bpm, p < 0.001], peak VO2 [32.34 (24.24-39.65) vs. 36.4 (28.56-52.71)ml/kg/min, p = 0.005], peak speed [5 (4-6.3) vs. 5.9 (4.0-6.3)mph, p = 0.001], time to exhaustion [11.5 (8.5-14.5) vs. 14 (11-18)min, p < 0.001], and working capacity on power [3.37 (2.04-5.6) vs. 3.89 (2.91-6.55)W/kg, p = 0.006] were significantly lower in JFM compared to controls. The frequency of chronotropic incompetence (≤80%) was significantly higher in JFM vs. controls (p = 0.0006). CONCLUSIONS: This study identified chronotropic incompetence and delayed HR recovery in JFM patients, indicating autonomic dysfunction. Aerobic exercise training should be considered in all JFM patients and may improve cardiac autonomic impairment, thus reducing cardiovascular risk.

OBJECTIVE: To evaluate demographic data and clinical and laboratory features at disease diagnosis in 3 different age groups of childhood-onset systemic lupus erythematosus (SLE): group A, early-onset (<6 years); group B, school age (≥6 to <12 years); and group C, adolescent (≥12 to <18 years). METHODS: This was a Brazilian multicenter cohort retrospective study in 10 pediatric rheumatology centers, including 847 childhood-onset SLE patients. RESULTS: Patients were divided into 3 groups: group A with 39 patients (4%), group B with 395 patients (47%), and group C with 413 patients (49%). Of 39 childhood-onset SLE patients in group A, 3 (8%) were ages <2 years, 4 (10%) were ≥2 to <3 years, and 32 (82%) were ≥3 and <6 years. A total of 74 childhood-onset SLE patients were analyzed for C1q levels, and complete C1q deficiency was observed in 3 of 74 patients (4%), all in group A. Groups were similar regarding high frequencies of female sex, nephritis, neuropsychiatric involvement, Systemic Lupus Erythematosus Disease Activity Index 2000 score ≥8, autoantibody profile, elevated acute phase proteins, and low complement levels (P > 0.05). However, the frequency of fever (78% versus 61% versus 47%; P < 0.0001), hepatomegaly (42% versus 29% versus 14%; P < 0.0001), splenomegaly (28% versus 12% versus 4%; P < 0.0001), and discoid lupus (13% versus 4% versus 4%; P = 0.020) was significantly higher in group A compared to groups B and C. The frequency of weight loss >2 kg (19% versus 28% versus 36%; P = 0.017), photosensitivity (34% versus 41% versus 51%; P = 0.006), leukopenia <4,000/mm3 (14% versus 25% versus 30%; P = 0.048), and lymphopenia <1,500/mm3 (22% versus 41% versus 47%; P = 0.011) was significantly lower in group A. CONCLUSION: Our large multicenter study identified the finding that the initial appearance of childhood-onset SLE is characterized by comparable high frequency of internal organ involvement and some distinct clinical and laboratory features in early-onset and adolescent groups.

Several studies point to the increased risk of reactivation of latent tuberculosis infection (LTBI) in patients with chronic inflammatory arthritis (CIAs) after using tumour necrosis factor (TNF)a blockers. To study the incidence of active mycobacterial infections (aMI) in patients starting TNFa blockers, 262 patients were included in this study: 109 with rheumatoid arthritis (RA), 93 with ankylosing spondylitis (AS), 44 with juvenile idiopathic arthritis (JIA) and 16 with psoriatic arthritis (PsA). All patients had indication for anti-TNFa therapy. Epidemiologic and clinical data were evaluated and a simple X-ray and tuberculin skin test (TST) were performed. The control group included 215 healthy individuals. The follow-up was 48 months to identify cases of aMI. TST positivity was higher in patients with AS (37.6%) than in RA (12.8%), PsA (18.8%) and JIA (6.8%) (p < 0.001). In the control group, TST positivity was 32.7%. Nine (3.43%) patients were diagnosed with aMI. The overall incidence rate of aMI was 86.93/100,000 person-years [95% confidence interval (CI) 23.6-217.9] for patients and 35.79/100,000 person-years (95% CI 12.4-69.6) for control group (p < 0.001). All patients who developed aMI had no evidence of LTBI at the baseline evaluation. Patients with CIA starting TNFa blockers and no evidence of LTBI at baseline, particularly with nonreactive TST, may have higher risk of aMI.

OBJECTIVE: To study the prevalence, risk factors, and mortality of invasive fungal infections (IFI) in patients with childhood-onset systemic lupus erythematosus (cSLE). METHODS: A retrospective multicenter cohort study was performed in 852 patients with cSLE from 10 pediatric rheumatology services. An investigator meeting was held and all participants received database training. IFI were diagnosed according to the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group Consensus Group criteria (proven, probable, and possible). Also evaluated were demographic, clinical, and laboratory data, and disease activity [SLE Disease Activity Index 2000 (SLEDAI-2K)], cumulative damage (Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index), treatment, and outcomes. RESULTS: IFI were observed in 33/852 patients (3.9%) with cSLE. Proven IFI was diagnosed in 22 patients with cSLE, probable IFI in 5, and possible IFI in 6. Types of IFI were candidiasis (20), aspergillosis (9), cryptococcosis (2), and 1 each disseminated histoplasmosis and paracoccidioidomycosis. The median of disease duration was lower (1.0 vs 4.7 yrs, p < 0.0001) with a higher current SLEDAI-2K [19.5 (0-44) vs 2 (0-45), p < 0.0001] and current prednisone (PRED) dose [50 (10-60) vs 10 (2-90) mg/day, p < 0.0001] in patients with IFI compared with those without IFI. The frequency of death was higher in the former group (51% vs 6%, p < 0.0001). Logistic regression analysis revealed that SLEDAI-2K (OR 1.108, 95% CI 1.057-1.163, p < 0.0001), current PRED dose (OR 1.046, 95% CI 1.021-1.071, p < 0.0001), and disease duration (OR 0.984, 95% CI 0.969-0.998, p = 0.030) were independent risk factors for IFI (R(2) Nagelkerke 0.425). CONCLUSION: To our knowledge, this is the first study to characterize IFI in patients with cSLE. We identified that disease activity and current glucocorticoid use were the main risk factors for these life-threatening infections, mainly in the first years of disease course, with a high rate of fatal outcome.

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in childhood. Without an effective therapy, patients may progress quickly to functional disability. Recently, depletion of B cells emerged as a new approach for the treatment of autoimmune diseases, including JIA. We describe six cases of JIA patients followed at a referral center for Rheumatology and Pediatric Rheumatology, submitted to treatment with rituximab (RTX) after refractoriness to three anti-TNF agents. Patients received RTX cycles with two infusions every six months. Response to treatment was assessed by DAS28, HAQ/CHAQ, and an overall assessment by the doctor and the patient. Of our six patients, four were girls (mean age at onset of disease: 6.1 years; mean disease evolution time: 15.1 years; mean age upon receiving RTX: 21.6 years). Four patients belonged to polyarticular subtype (1 rheumatoid factor [RF]-negative, 3 FR-positive), a patient with systemic JIA subtype with a polyarticular course and arthritis related to enthesitis. Of our six patients, five responded to treatment; and during the course of 12 months, the clinical response was maintained, although not sustained. However, discontinuation by infusion reactions caused the withdrawal of RTX in two patients. The use of RTX in JIA is restricted to cases refractory to other biological agents and, even considering that this study was held in a small number of advanced patients, RTX proved to be an effective therapeutic option.

INTRODUCTION: Paediatric rheumatology (PR) is an emerging specialty, practised by a limited number of specialists. Currently, there is neither a record of the profile of rheumatology patients being treated in Brazil nor data on the training of qualified rheumatology professionals in the country. OBJECTIVE: To investigate the profile of PR specialists and services, as well as the characteristics of paediatric patients with rheumatic diseases, for estimating the current state of rheumatology in the state of São Paulo. PATIENTS AND METHODS: In 2010, the scientific department of PR of the Paediatric Society of São Paulo administered a questionnaire that was answered by 24/31 accredited specialists in PR practising in state of São Paulo and by 8/21 institutions that provide PR care. RESULTS: Most (91%) of the surveyed professionals practise in public institutions. Private clinics (28.6%) and public institutions (37.5%) reported not having access to nailfold capillaroscopy, and 50% of the private clinics reported not having access to acupuncture. The average duration of professional practise in PR was 9.4 years, and 67% of the physicians had attended postgraduate programmes. Seven (87.5%) public institutions perform teaching activities, in which new paediatric rheumatologists are trained, and five (62.5%) offer postgraduate programmes. Two-thirds of the surveyed specialists use immunosuppressants and biological agents classified as "restricted use" by the Health Secretariat. The disease most frequently reported was juvenile idiopathic arthritis (29.1-34.5%), followed by juvenile systemic lupus erythematosus (JSLE) (11.6-12.3%) and rheumatic fever (9.1-15.9%). The incidence of vasculitis (including Henoch-Schönlein purpura, Wegener's granulomatosis, and Takayasu's arteritis) and autoinflammatory syndromes was higher in public institutions compared to other institutions (P = 0.03, P = 0.04, P = 0.002, and P < 0.0001, respectively). Patients with JSLE had the highest mortality rate (68% of deaths), mainly due to infection. CONCLUSION: The field of PR in the state of São Paulo has a significant number of specialists with postgraduate degrees who mostly practise at teaching institutions with infrastructures appropriate for the care of high-complexity patients.

INTRODUÇÃO: A reumatologia pediátrica (RP) é uma especialidade emergente, com número restrito de especialistas, e ainda não conta com uma casuística brasileira sobre o perfil dos pacientes atendidos e as informações sobre a formação de profissionais capacitados. OBJETIVO: Estudar o perfil dos especialistas e dos serviços em RP e as características dos pacientes com doenças reumáticas nessa faixa etária a fim de estimar a situação atual no estado de São Paulo (ESP). PACIENTES E MÉTODOS: No ano de 2010 o departamento científico de RP da Sociedade de Pediatria de São Paulo encaminhou um questionário respondido por 24/31 especialistas com título de especialização em RP que atuam no ESP e por 8/12 instituições com atendimento nesta especialidade. RESULTADOS: A maioria (91%) dos profissionais exerce suas atividades em instituições públicas. Clínicas privadas (28,6%) e instituições (37,5%) relataram não ter acesso ao exame de capilaroscopia e 50% das clínicas privadas não tem acesso à acupuntura. A média de tempo de prática profissional na especialidade foi de 9,4 anos, sendo 67% deles pós-graduados. Sete (87,5%) instituições públicas atuam na área de ensino, formando novos reumatologistas pediátricos. Cinco (62,5%) delas têm pós-graduação. Dois terços dos especialistas utilizam imunossupressores e agentes biológicos de uso restrito pela Secretaria da Saúde. A doença mais atendida foi artrite idiopática juvenil (29,1%-34,5%), seguida de lúpus eritematoso sistêmico juvenil (LESJ) (11,6%-12,3%) e febre reumática (9,1%-15,9%). Vasculites (púrpura de Henoch Schönlein, Wegener, Takayasu) e síndromes autoinflamatórias foram mais incidentes nas instituições públicas (P = 0,03; P = 0,04; P = 0,002 e P < 0,0001, respectivamente). O LESJ foi a doença com maior mortalidade (68% dos óbitos), principalmente por infecção. CONCLUSÃO: A RP no ESP conta com um número expressivo de especialistas pós-graduados, que atuam especialmente em instituições de ensino, com infraestrutura adequada ao atendimento de pacientes de alta complexidade.

OBJECTIVE: There are several factors that contribute to poor adherence to treatment in children and adolescents with chronic rheumatic diseases, worsening their quality of life and prognosis. Our aim was to assess the rates of adherence to treatment and to identify the socioeconomic and clinical factors associated. METHODS: The sample included 99 patients with juvenile idiopathic arthritis, systemic erythematosus lupus, dermatomyositis or juvenile scleroderma. All patients were followed at the outpatient pediatric rheumatology for a minimum period of 6 months. To assess adherence, a questionnaire was administered to the providers, which included three blocks: 1) demographic, clinical and laboratory data; 2) medication adherence; and 3) attending follow-up appointments, examinations and use of orthoses. A value lower than or equal to 80% of the prescribed was considered poor adherence. RESULTS: A total of 53% of patients showed good overall adherence, observed when the caregiver lived in a stable union marital status (p = 0.006); 20 patients (20.2%) presented poor medication adherence, related to the use of three or more medications daily (p = 0.047). The causes of poor adherence were forgetfulness, refusal, incorrect dose or lack of medication, personal problems, and financial difficulties. CONCLUSIONS: We observed good overall treatment adherence in patients whose providers lived in stable union and poor adherence to medication in patients who used more than three types of medication daily. There was no association between the adherence rates and sex, age, time since diagnosis and disease activity.

OBJETIVO: São vários os fatores que contribuem para a má adesão ao tratamento de crianças e adolescentes com doenças reumáticas crônicas, gerando piora da qualidade de vida e do prognóstico. Nosso objetivo foi avaliar as taxas de adesão ao tratamento e identificar os fatores socioeconômicos e clínicos associados. MÉTODOS: Foram incluídos 99 pacientes com artrite idiopática juvenil, lúpus eritematoso sistêmico, dermatomiosite ou esclerodermia juvenil. Todos os pacientes eram acompanhados no ambulatório de reumatologia pediátrica por um período mínimo de 6 meses. Para avaliação da adesão, foi aplicado aos cuidadores um questionário composto por três blocos: 1) dados demográficos, clínicos e laboratoriais; 2) adesão ao tratamento medicamentoso; e 3) comparecimento às consultas, realização de exames e utilização de órteses. Foi considerada má adesão, quando realizado valor menor ou igual a 80% do prescrito. RESULTADOS: Um total de 53% dos pacientes apresentou boa adesão ao tratamento global, observada quando o cuidador possuía união estável (p = 0,006); 20 pacientes (20,2%) apresentaram má adesão ao tratamento medicamentoso, relacionada à utilização de mais que três medicamentos diários (p = 0,047). As causas de má adesão ao tratamento foram esquecimento, recusa, dose incorreta ou falta de medicamento, problemas pessoais e dificuldades financeiras. CONCLUSÕES: Observamos boa adesão ao tratamento global nos pacientes cujos cuidadores possuíam união estável e má adesão ao tratamento medicamentoso nos pacientes que utilizavam mais que três tipos de medicamentos diariamente. Não houve associação entre as taxas de adesão ao tratamento e sexo, idade, tempo de diagnóstico e atividade da doença.
OBJECTIVE: There are several factors that contribute to poor adherence to treatment in children and adolescents with chronic rheumatic diseases, worsening their quality of life and prognosis. Our aim was to assess the rates of adherence to treatment and to identify the socioeconomic and clinical factors associated. METHODS: The sample included 99 patients with juvenile idiopathic arthritis, systemic erythematosus lupus, dermatomyositis or juvenile scleroderma. All patients were followed at the outpatient pediatric rheumatology for a minimum period of 6 months. To assess adherence, a questionnaire was administered to the providers, which included three blocks: 1) demographic, clinical and laboratory data; 2) medication adherence; and 3) attending follow-up appointments, examinations and use of orthoses. A value lower than or equal to 80% of the prescribed was considered poor adherence. RESULTS: A total of 53% of patients showed good overall adherence, observed when the caregiver lived in a stable union marital status (p = 0.006); 20 patients (20.2%) presented poor medication adherence, related to the use of three or more medications daily (p = 0.047). The causes of poor adherence were forgetfulness, refusal, incorrect dose or lack of medication, personal problems, and financial difficulties. CONCLUSIONS: We observed good overall treatment adherence in patients whose providers lived in stable union and poor adherence to medication in patients who used more than three types of medication daily.

OBJECTIVES: The aim of the present paper is to evaluate the immune response and tolerability of varicella vaccine in children and adolescents with systemic lupus erythematosus previously exposed to varicella-zoster virus. METHODS: We performed a prospective and controlled study on a group of 54 SLE patients that were chosen at random to be or not to be vaccinated (28 were vaccinated and 26 were not). Twenty-eight healthy controls, of matching age and sex were also vaccinated. All were submitted to a questionnaire, physical evaluation and laboratory assays: lymphocyte immune-phenotyping by flow cytometry, plasma varicella zoster virus (VZV) serology by ELISA and in vitro interferon gamma (IFNγ) production by T-cells after stimulus with VZV antigen. They were evaluated before vaccination and at 30, 45, 180 and 360 days afterwards. RESULTS: We did not observe any differences in the frequency of adverse events in both vaccinated groups. At study entry, all individuals were seropositive for VZV antibodies. The serum VZV antibody titres similarly increased after vaccination. The frequency of flares and the SLEDAI score were also similar among the patients. Thirty days after vaccination the production of IFNγ specific to VZV was lower in the SLE group compared to healthy controls. In the follow-up we observed 4 cases of herpes zoster in the SLE unvaccinated group, but no zoster in the vaccinated group. CONCLUSIONS: The varicella vaccine was well tolerated in SLE group, who had pre-existing immunity to varicella. The varicella vaccine immunogenicity measurement by serum antibody titres was appropriate. The incidence of HZ was lower in the vaccinated lupus group.

OBJECTIVE: To assess the frequency of calcinosis in patients with juvenile dermatomyositis, and the possible risk factors for that manifestation. METHODS: Medical record review of 34 patients, with an emphasis on the following characteristics: demographic, clinical and laboratory data; type of treatment; adherence to treatment; disease course (monocyclic, chronic and polycyclic); and disease severity. Patients were divided into two groups as follows: those who developed calcinosis (up to the sixth month of follow-up and after six months of follow-up) and those who did not develop calcinosis. Twenty-seven patients underwent two nailfold capillaroscopies (NFC), which were considered altered when the scleroderma pattern was found. RESULTS: The mean age of symptom onset of the 34 patients was 6.5 years, the time until diagnosis was 1.2 years, and 70% were females. Half of the patients had a monocyclic disease course, and only 14.7% had severe vasculitis. Almost 90% of the patients undergoing NFC showed a change on the first assessment, 74% showed a change on the second assessment, and the mean interval between both assessments was 1.6 year. Calcinosis was evidenced in 16 (47.1%) patients. No association was observed between the variables analyzed and the development of calcinosis. CONCLUSION: No risk factors for calcinosis were identified in this study, although that complication was found in half of the patients with juvenile dermatomyositis studied.

OBJETIVO: Avaliar a frequência de calcinose em pacientes com dermatomiosite juvenil, bem como estudar possíveis fatores de risco para essa manifestação. MÉTODOS: Revisão de prontuários de 34 pacientes, com ênfase nas características demográficas, clínicas e laboratoriais, tipo de tratamento e adesão, tipo de evolução (monocíclico, crônico e policíclico) e gravidade da doença. Os pacientes foram separados em grupos: aqueles que desenvolveram calcinose (até o sexto mês de acompanhamento ambulatorial e após seis meses de acompanhamento) e os que não desenvolveram calcinose. Vinte e sete pacientes fizeram dois exames de capilaroscopia periungueal (CPU), os quais foram considerados alterados quando era encontrado padrão escleroderma. RESULTADOS: A média de idade de início dos sintomas dos 34 pacientes foi de 6,5 anos, e o tempo até o diagnóstico foi de 1,2 anos. Setenta por cento eram meninas. Metade dos pacientes teve curso monocíclico da doença, e apenas 14,7% tiveram vasculite grave. Quase 90% dos pacientes que realizaram CPU tiveram alteração na primeira avaliação, e 74% tiveram alteração na segunda avaliação, com uma média de 1,6 anos entre as duas. Dezesseis (47,1%) pacientes apresentaram calcinose. Não houve associação entre as variáveis analisadas e o desenvolvimento da calcinose. CONCLUSÃO: Não conseguimos demonstrar a presença de fatores de risco para calcinose, apesar de termos encontrado uma frequência dessa complicação em cerca de metade dos pacientes com dermatomiosite juvenil.

INTRODUCTION: Bisphosphonates inhibit bone resorption by interfering with the action of osteoclasts. Among the adverse effects, sclerotic lines observed in the metaphysis of long bones have been described as the main imaging finding in pediatric patients. OBJECTIVE: To evaluate the frequency of radiographic changes caused by alendronate in children and adolescents with low bone density or calcinosis. PATIENTS AND METHODS: We conducted a cross-sectional study with 21 patients who were treated with once-weekly alendronate for at least 10 months. Patients underwent x-rays of long bones before the start of alendronate and approximately one year after its use. RESULTS: Eleven patients (52.3%) had sclerotic lines in the metaphysis of long bones. The most frequent site was the tibia (8/11 patients), followed by the femur (7/11), humerus (6/11), radius (4/11), ulna (3/11), and fibula (2/11). Regression of radiographic changes during the study period (up to 1.1 years after discontinuation of alendronate) was not observed. CONCLUSION: If used carefully, alendronate is safe and radiographic changes have not been shown to be clinically relevant.

INTRODUCTION/OBJECTIVES: Evaluate clinical practice through assessment of vaccination card and recommendation of specific vaccines in pediatric patients with rheumatic diseases in use of different drugs and reveal the possible association between vaccination frequency and time of the clinical practice of pediatric rheumatologists in the state of São Paulo. MATERIAL AND METHODS: A questionnaire was sent to pediatric rheumatologists of the Departamento de Reumatologia da Sociedade de Pediatria de São Paulo. This instrument included questions about practice time on Pediatric Rheumatology, vaccination of patients with juvenile systemic lupus erythematosus (JSLE), juvenile idiopathic arthritis (JIA), juvenile dermatomyositis (JDM), and immunization according to the treatments used. RESULTS: Vaccination card was seen by 100% of the professionals at the first visit and by 36% annually. Vaccines of live agents were not recommended for patients with JSLE, JIA, and JDM in 44%, 64%, and 48%, respectively. The professionals were divided into two groups: Group A (≤ 15 years of practice, n = 12) and B (≥ 16 years, n = 13). No statistical difference was observed in the use of live agent vaccine and vaccines with inactivated agents or protein components in the two treatment groups (P > 0.05). Moreover, the groups had similar opinion regarding severity of immunosuppression in patients with JSLE, JIA, and JDM (with or without activity) and treatment used (P > 0.05). CONCLUSIONS: The frequency of immunization by pediatric rheumatologists in São Paulo is low, especially after the first visit, and not influenced by time of professional practice.

INTRODUÇÃO/OBJETIVOS: Avaliar a prática clínica com relação à verificação do cartão vacinal e à indicação de vacinas específicas em pacientes com doenças reumáticas pediátricas em uso de diferentes drogas, e evidenciar a possível associação entre frequência de vacinação e tempo de prática clínica dos reumatologistas pediátricos do estado de São Paulo. MATERIAL E MÉTODOS: Um questionário foi enviado para os reumatologistas pediátricos do Departamento de Reumatologia da Sociedade de Pediatra de São Paulo. Esse instrumento incluiu questões sobre tempo de prática em Reumatologia Pediátrica, vacinação de pacientes com Lúpus Eritematoso Sistêmico Juvenil (LESJ), artrite idiopática juvenil (AIJ), dermatomiosite juvenil (DMJ) e imunização de acordo com os tratamentos utilizados. RESULTADOS: Cartão de vacinação foi visto por 100 por cento dos profissionais na primeira consulta e por 36 por cento anualmente. Vacinas de agentes vivos não foram recomendadas para pacientes com LESJ, AIJ e DMJ em 44 por cento, 64 por cento e 48 por cento, respectivamente. Os profissionais foram divididos em dois grupos: A (< 15 anos de prática, n = 12) e B (> 16 anos, n = 13). Nenhuma diferença estatística foi observada no uso de vacinas de agentes vivos e vacinas de agentes inativos ou componentes proteicos em relação ao tratamento nos dois grupos (P > 0,05). Além disso, os grupos foram similares em relação à opinião sobre a gravidade de imunossupressão em pacientes com LESJ, AIJ e DMJ com ou sem atividade e a terapêutica utilizada (P > 0,05). CONCLUSÕES: A frequência de vacinação por reumatologistas pediátricos de São Paulo é baixa, especialmente após a primeira consulta, e não é influenciada pelo tempo de prática profissional.

INTRODUÇÃO: Os bisfosfonatos inibem a reabsorção óssea pela interferência na ação dos osteoclastos. Dentre os efeitos adversos, as linhas escleróticas em metáfise de ossos longos são descritas como principal alteração radiográfica na faixa etária pediátrica. OBJETIVO: Avaliar a frequência de alterações radiográficas causadas pelo alendronato utilizado em crianças e adolescentes com baixa densidade óssea ou calcinose. PACIENTES E MÉTODOS: Foi realizado um estudo do tipo coorte retrospectiva analisando-se prontuários de 21 pacientes que fizeram uso de alendronato semanal por no mínimo 10 meses. Os pacientes realizaram radiografias de ossos longos antes do início do alendronato e aproximadamente um ano após o seu uso. RESULTADOS: Onze pacientes (52,3 por cento) apresentaram linhas escleróticas em metáfise dos ossos longos. A localização mais frequente foi em tíbia (8/11 pacientes), seguida de fêmur (7/11), úmero (6/11), rádio (4/11), ulna (3/11) e fíbula (2/11). Nenhum paciente apresentou regressão das alterações radiográficas durante o tempo de evolução (até 1,1 ano após a suspensão do alendronato). CONCLUSÃO: Se usado com critério, o alendronato é seguro e as alterações radiográficas não mostraram ter um significado mais importante.
