- Vasculite digital inicial em uma grande coorte multicêntrica de pacientes com lúpus eritematoso sistêmico de início na infância(2017) SAKAMOTO, Ana Paula; SILVA, Clovis Artur; SILVA, Marco Felipe Castro da; LOPES, Anandreia Simoes; RUSSO, Gleice Clemente Souza; SALLUM, Adriana Maluf Elias; KOZU, Katia; BONFA, Eloisa; SAAD-MAGALHAES, Claudia; PEREIRA, Rosa Maria Rodrigues; LEN, Claudio Arnaldo; TERRERI, Maria TeresaObjectives: To assess clinical digital vasculitis (DV) as an initial manifestation of childhood onset systemic lupus erythematosus (cSLE) within a large population. Methods: Multicenter cross-sectional study including 852 cSLE patients (ACR criteria) followed in ten Pediatric Rheumatology centers in Sao Paulo State, Brazil. Results: DV was observed in 25/852 (3%) cSLE patients. Periungual hemorrhage was diagnosed in 12 (48%), periungual infarction in 7 (28%), tip finger ulceration in 4 (16%), painful nodules in 1 (4%) and gangrene in 1 (4%). A poor outcome, with digital resorption, occurred in 5 (20%). Comparison of patients with and without DV revealed higher frequency of malar rash (80% vs. 53%, p = 0.008), discoid rash (16% vs. 4%, p = 0.017), photosensitivity (76% vs. 45%, p = 0.002) and other cutaneous vasculitides (80% vs. 19%, p <0.0001), whereas the frequency of overall constitutional features (32% vs. 61%, p = 0.003), fever (32% vs. 56%, p = 0.020) and hepatomegaly (4% vs. 23%, p = 0.026) were lower in these patients. Frequency of female gender, severe multi-organ involvement, autoantibodies profile and low complement were alike in both groups (p >0.05). SLEDAI-2K median, DV descriptor excluded, was significantly lower in patients with DV compared to those without this manifestation [10 (0-28) vs. 14 (0-58), p = 0.004]. Visceral vasculitis or death were not observed in this cSLE cohort. The frequency of cyclophosphamide use (0% vs. 18%, p = 0.014) was significantly lower in the DV group. Conclusion: Our large multicenter study identified clinical DV as one of the rare initial manifestation of active cSLE associated with a mild multisystemic disease, in spite of digital resorption in some of these patients.

- Features of 847 Childhood-Onset Systemic Lupus Erythematosus Patients in Three Age Groups at Diagnosis: A Brazilian Multicenter Study(2016) GOMES, Roberta C.; SILVA, Marco F.; KOZU, Katia; BONFA, Eloisa; PEREIRA, Rosa M.; TERRERI, Maria T.; MAGALHAES, Claudia S.; SACCHETTI, Silvana B.; MARINI, Roberto; FRAGA, Melissa; CARVALHO, Luciana M.; BARBOSA, Cassia M.; CARNEIRO-SAMPAIO, Magda; SILVA, Clovis A.ObjectiveTo 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). MethodsThis was a Brazilian multicenter cohort retrospective study in 10 pediatric rheumatology centers, including 847 childhood-onset SLE patients. ResultsPatients 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/mm(3) (14% versus 25% versus 30%; P=0.048), and lymphopenia <1,500/mm(3) (22% versus 41% versus 47%; P=0.011) was significantly lower in group A. ConclusionOur 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.
- Chronic Spontaneous Urticaria: A Survey of 852 Cases of Childhood-Onset Systemic Lupus Erythematosus(2015) FERRIANI, Mariana Paes Leme; SILVA, Marco Felipe Castro; PEREIRA, Rosa Maria Rodrigues; TERRERI, Maria Teresa; MAGALHAES, Claudia Saad; BONFA, Eloisa; PASTORINO, Antonio C.; SANTOS, Maria Carolina dos; APPENZELLER, Simone; FERRIANI, Virginia Paes Leme; LEN, Claudio Arnaldo; SALLUM, Adriana Maluf Elias; LIBORIO, Jonatas; CASTRO, Tania Caroline Monteiro de; SILVA, Clovis ArturBackground: Data regarding the prevalence of chronic spontaneous urticaria (CSU) in childhood-onset systemic lupus erythematosus (cSLE) patients and possible associated factors are limited to a few case reports. The objectives of this study were to assess CSU in a large cSLE population, in order to evaluate the demographic data, clinical manifestations, disease activity/damage, laboratory abnormalities and treatment. Methods: A retrospective multicenter cohort study (Brazilian cSLE group) was performed in 10 Pediatric Rheumatology services and included 852 cSLE patients. CSU was diagnosed according to the guidelines of the European Academy of Allergy and Clinical Immunology, the Global Allergy and Asthma European Network, the European Dermatology Forum and the World Allergy Organization. Patients with CSU (evaluated at urticaria diagnosis) and patients without CSU (evaluated at the last visit) were assessed for lupus clinical/laboratory features and treatment. Results: CSU was observed in 10/852 cSLE patients (1.17%). The median of cSLE duration at urticaria diagnosis was 0 (-3 to 5) years. Comparison of cSLE patients with and without CSU revealed a greater frequency of constitutional symptoms (40 vs. 8%, p = 0.006), reticuloendothelial system involvement (30 vs. 3%, p = 0.003), mucocutaneous (90 vs. 28%, p < 0.0001) and musculoskeletal manifestations (50 vs. 6%, p < 0.0001) and methylprednisolone pulse therapy use (60 vs. 9%, p < 0.0001) in the former group. The frequency of immunosuppressive treatment was lower in patients with CSU (p = 0.018). The median SLE Disease Activity Index 2000 (12 vs. 2, p < 0.0001) and erythrocyte sedimentation rate (40 vs. 19 mm/1st hour, p = 0.024), was higher in patients with CSU. Conclusions: To our knowledge, this is the first study with evidence that CSU may be linked to cSLE. We also demonstrated that this particular skin manifestation occurs predominantly at disease onset and is associated with lupus moderate/high disease activity without major organ involvement.

- Liver and spleen biometrics in childhood-onset systemic lupus erythematosus patients(2015) GUARIENTO, Andressa; SILVA, Marco Felipe C.; TASSETANO, Priscilla S. F.; ROCHA, Silvia Maria S.; CAMPOS, Lucia M. A.; VALENTE, Marcelo; SILVA, Clovis A.Objective: To evaluate liver and spleen dimensions in childhood-onset systemic lupus erythematosus (c-SLE) patients and healthy controls. Methods: 30 c-SLE patients and 30 healthy control volunteers underwent abdominal ultrasound. The following two liver measurements were performed in left hepatic lobe: craniocaudal and anteroposterior and three in right hepatic lobe (RHL): posterior craniocaudal (PCC-RHL), anterior craniocaudal and anteroposterior. Three spleen dimension measurements were also evaluated: longitudinal, transverse and anteroposterior. Demographic, clinical and laboratorial data, SLEDAI-2K, ECLAM, SLAM and treatment were assessed. Results: Mean current age was similar in c-SLE and controls (170.31 +/- 27.81 vs. 164.15 +/- 39.25 months; p = 0.486). The mean of PCC-RHL dimension was significantly higher in c-SLE compared to controls (13.30 +/- 1.85 vs. 12.52 +/- 0.93, p = 0.044). There were no differences between the other hepatic biometrics and splenic parameters (p > 0.05). Further analysis in c-SLE patients according to PCC-FtHL dimension >= 13.3 cm versus <13.3 cm showed that the median of SLEDAI-2K [8 (0-18) vs. 2 (0-8), p = 0.004], ECLAM 14 (0-9) vs. 2 (0-5), p = 0.0191 and SLAM [5 (1-13) vs. 2 (0-14), p = 0.016] were significantly higher in patients with higher PCC-RHL dimension, likewise the frequencie of nephritis (77% vs. 29%, p = 0.010). Liver enzymes were similar in both groups (p > 0.05). Positive correlation was observed between SLEDAI-2K and PCC-RHL (p = 0.001, r = +0.595). Negative correlation was evidenced between disease duration and longitudinal dimension of spleen (p = 0.031, r = -0.394). Conclusion: Our data raises the possibility that disease activity could lead to a subclinical and localized hepatomegaly during the disease course. Long disease duration resulted to spleen atrophy in c-SLE patients.
- A Multicenter Study of Invasive Fungal Infections in Patients with Childhood-onset Systemic Lupus Erythematosus(2015) SILVA, Marco F.; FERRIANI, Mariana P.; TERRERI, Maria T.; PEREIRA, Rosa M.; MAGALHAES, Claudia S.; BONFA, Eloisa; CAMPOS, Lucia M.; OKUDA, Eunice M.; APPENZELLER, Simone; FERRIANI, Virginia P.; BARBOSA, Cassia M.; RAMOS, Valeria C.; LOTUFO, Simone; SILVA, Clovis A.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.
