- Symptomatic polyautoimmunity at diagnosis of 1463 childhood-onset lupus: A Brazilian multicenter study(2018) SETOUE, Debora N.; PITTA, Ana C.; FIOROT, Fernanda J.; NASTRI, Mariana M.; NOVAK, Glaucia V.; MOLINARI, Beatriz C.; OLIVEIRA, Juliana C.; GORMEZANO, Natali W.; SAKAMOTO, Ana P.; TERRERI, Maria T.; PEREIRA, Rosa M.; SAAD-MAGALHAES, Claudia; SALLUM, Adriana M.; KOZU, Katia; FRAGA, Melissa M.; PIOTTO, Daniela P.; CLEMENTE, Gleice; MARINI, Roberto; GOMES, Hugo R.; RABELO-JUNIOR, Carlos N.; FELIX, Marta M.; RIBEIRO, Maria C.; ALMEIDA, Rozana G.; ASSAD, Ana P.; SACCHETTI, Silvana B.; BARROS, Leandra C.; BONFA, Eloisa; SILVA, Clovis A.Objective: To evaluate symptomatic polyautoimmunity (PA) at childhood-onset systemic lupus erythematosus (cSLE) diagnosis, and its association with demographic data, disease activity, clinical manifestations and laboratorial abnormalities in a large Brazilian cSLE population. Methods: A multicenter retrospective study was performed in 1463 cSLE(ACR criteria) patients from 27 Pediatric Rheumatology services. Symptomatic PA was defined according to the presence of more than one concomitant autoimmune disease(AD) and symptomatic multiple autoimmune syndrome(MAS) was defined as three or more AD. An investigator meeting was held to define the protocol. Demographic data, SLICC classification criteria and SLEDAI-2K were evaluated. Results: At cSLE diagnosis symptomatic PA was observed in 144/1463(9.8%) and symptomatic MAS occurred in solely 10/1463(0.7%). In the former group the more frequently observed associated AD were Hashimoto thyroiditis n = 42/144(29%), antiphospholipid syndrome n = 42/144(29%), autoimmune hepatitis n = 26/144(18%) and type 1 diabetes mellitus n = 23/144(15.9%). Further comparisons between cSLE patients with and without PA showed a higher median age(p = 0.016) and lower mean SLICC criteria (p = 0.039) in those with PA. Additionally, these cSLE patients had less renal involvement(35% vs. 44%, p = 0.038) and red blood cell cast(6% vs. 12%, p = 0.042) and more antiphospholipid antibodies(29% vs. 15%, p < 0.0001). Conclusions: Approximately 10% of cSLE had symptomatic PA at diagnosis, particularly endocrine autoimmune disorders and antiphospholipid syndrome. Lupus was characterized by a mild disease onset and MAS was infrequently evidenced. Further studies are necessary to determine if this subgroup of cSLE patients have a distinct genetic background with a less severe disease and a better long-term outcome.
- Diffuse alveolar hemorrhage in childhood-onset systemic lupus erythematosus: a severe disease flare with serious outcome(2018) BLAY, Gabriela; RODRIGUES, Joaquim C.; FERREIRA, Juliana C. O.; LEAL, Gabriela N.; GORMEZANO, Natali W.; V, Glaucia Novak; PEREIRA, Rosa M. R.; TERRERI, Maria T.; MAGALHAES, Claudia S.; MOLINARI, Beatriz C.; SAKAMOTO, Ana P.; AIKAWA, Nadia E.; CAMPOS, Lucia M. A.; FERNANDES, Taciana A. P.; CLEMENTE, Gleice; PERACCHI, Octavio A. B.; BUGNI, Vanessa; MARINI, Roberto; SACCHETTI, Silvana B.; CARVALHO, Luciana M.; FRAGA, Melissa M.; CASTRO, Tania C. M.; RAMOS, Valeria C.; BONFA, Eloisa; SILVA, Clovis A.Objective: To evaluate prevalence, clinical manifestations, laboratory abnormalities and treatment in a multicenter cohort study including 847 childhood-onset systemic lupus erythematosus (cSLE) patients with and without diffuse alveolar hemorrhage (DAH), as well as concomitant parameters of severity. Methods: DAH was defined as the presence of at least three respiratory symptoms/signs associated with diffuse interstitial/alveolar infiltrates on chest x-ray or high-resolution computer tomography and sudden drop in hemoglobin levels. Statistical analysis was performed using Bonferroni correction (p<0.0022). Results: DAH was observed in 19/847 (2.2%) cSLE patients. Cough/dyspnea/tachycardia/hypoxemia occurred in all cSLE patients with DAH. Concomitant parameters of severity observed were: mechanical ventilation in 14/19 (74%), hemoptysis 12/19 (63%), macrophage activation syndrome 2/19 (10%) and death 9/19 (47%). Further analysis of cSLE patients at DAH diagnosis compared to 76 cSLE control patients without DAH with same disease duration [3 (1-151) vs. 4 (1-151) months, p = 0.335], showed higher frequencies of constitutional involvement (74% vs. 10%, p < 0.0001), serositis (63% vs. 6%, p < 0.0001) and sepsis (53% vs. 9%, p < 0.0001) in the DAH group. The median of disease activity score(SLEDAI-2 K) was significantly higher in cSLE patients with DAH [18 (5-40) vs. 6 (0-44), p < 0.0001]. The frequencies of thrombocytopenia (53% vs. 12%, p < 0.0001), intravenous methylprednisolone (95% vs. 16%, p < 0.0001) and intravenous cyclophosphamide (47% vs. 8%, p < 0.0001) were also significantly higher in DAH patients. Conclusions: This was the first study to demonstrate that DAH, although not a disease activity score descriptor, occurred in the context of significant moderate/severe cSLE flare. Importantly, we identified that this condition was associated with serious disease flare complicated by sepsis with high mortality rate.

- Characteristics of 1555 childhood-onset lupus in three groups based on distinct time intervals to disease diagnosis: a Brazilian multicenter study(2018) V, G. Novak; MOLINARI, B. C.; FERREIRA, J. C.; SAKAMOTO, A. P.; TERRERI, M. T.; PEREIRA, R. M. R.; SAAD-MAGALHAES, C.; AIKAWA, N. E.; CAMPOS, L. M.; LEN, C. A.; APPENZELLER, S.; FERRIANI, V. P.; SILVA, M. F.; OLIVEIRA, S. K.; ISLABDO, A.

C.; GUIMARACS, L. J.; SANTOS, F. P.; SILVA, C. T.; BONFA, E.; SILVA, C. A.Objective The objective of this study was to compare demographic data, clinical/laboratorial features and disease activity at diagnosis in three different groups with distinct time intervals between onset of signs/symptoms and disease diagnosis. Methods A multicenter study was performed in 1555 childhood-onset systemic lupus erythematosus (American College of Rheumatology criteria) patients from 27 pediatric rheumatology services. Patients were divided into three childhood-onset systemic lupus erythematosus groups: A: short time interval to diagnosis (<1 month); B: intermediate time interval (1 and <3 months); and C: long time interval (3 months). An investigator meeting was held to define the protocol. Demographic data, SLICC classification criteria and SLEDAI-2K were evaluated. Results The number of patients in each group was: A=60 (4%); B=522 (33.5%); and C=973 (62.5%). The median age at diagnosis (11.1 (4.2-17) vs. 12 (1.9-17.7) vs. 12.5 (3-18) years, P=0.025) was significantly lower in group A compared with groups B and C. The median number of diagnostic criteria according to SLICC (7 (4-12) vs. 6 (4-13) vs. 6 (4-12), P<0.0001) and SLEDAI-2K (18 (6-57) vs. 16 (2-63) vs. 13 (1-49), P<0.0001) were significantly higher in group A than the other two groups. The frequency of oral ulcers in the palate (25% vs. 15% vs. 11%, P=0.003), pleuritis (25% vs. 24% vs. 14%, P<0.0001), nephritis (52% vs. 47% vs. 40%, P=0.009), neuropsychiatric manifestations (22% vs. 13% vs. 10%, P=0.008), thrombocytopenia (32% vs. 18% vs. 19%, P=0.037), leucopenia/lymphopenia (65% vs. 46% vs. 40%, P<0.0001) and anti-dsDNA antibodies (79% vs. 66% vs. 61%, P=0.01) were significantly higher in group A compared with the other groups. In contrast, group C had a less severe disease characterized by higher frequencies of synovitis (61% vs. 66% vs. 71%, P=0.032) and lower frequencies of serositis (37% vs. 33% vs. 25%, P=0.002), proteinuria >500mg/day (48% vs. 45% vs. 36%, P=0.002) and low complement levels (81% vs. 81% vs. 71%, P<0.0001) compared with groups A or B. Conclusions Our large Brazilian multicenter study demonstrated that for most childhood-onset systemic lupus erythematosus patients, diagnosis is delayed probably due to mild disease onset. Conversely, the minority has a very short time interval to diagnosis and a presentation with a more severe and active multisystemic condition.
