- Anti-ribosomal P antibody: a multicenter study in childhood-onset systemic lupus erythematosus patients(2017) VALOES, C. C. M.; MOLINARI, B. C.; PITTA, A. C. G.; GORMEZANO, N. W. S.; FARHAT, S. C. L.; KOZU, K.; SALLUM, A. M. E.; APPENZELLER, S.; SAKAMOTO, A. P.; TERRERI, M. T.; PEREIRA, R. M. R.; MAGALHAES, C. S.; FERREIRA, J. C. O. A.; BARBOSA, C. M.; GOMES, F. H.; BONFA, E.; SILVA, C. A.Objectives: Anti-ribosomal P protein (anti-P) autoantibodies are highly specific for systemic lupus erythematosus (SLE). However, the evaluation of this autoantibody in childhood-onset SLE (cSLE) populations has been limited to a few small series, hampering the interpretation of the clinical and laboratorial associations. Therefore, the objective of this multicenter cohort study was to evaluate demographic, clinical/laboratorial features, and disease damage score in cSLE patients with and without the presence of anti-P antibody. Methods: This was a retrospective multicenter study performed in 10 pediatric rheumatology services of Sao Paulo state, Brazil. Anti-P antibodies were measured by ELISA in 228 cSLE patients. Results: Anti-P antibodies were observed in 61/228 (27%) cSLE patients. Frequencies of cumulative lymphadenopathy (29% vs. 15%, p = 0.014), acute confusional state (13% vs. 5%, p = 0.041), mood disorder (18% vs. 8%, p = 0.041), autoimmune hemolytic anemia (34% vs. 15%, p = 0.001), as well as presence of anti-Sm (67% vs. 40%, p = 0.001), anti-RNP (39% vs. 21%, p = 0.012) and anti-Ro/SSA antibodies (43% vs. 25%, p = 0.016) were significantly higher in cSLE patients with anti-P antibodies compared to those without these autoantibodies. A multiple regression model revealed that anti-P antibodies were associated with autoimmune hemolytic anemia (odds ratio (OR) = 2.758, 95% confidence interval (CI): 1.304-5.833, p = 0.008) and anti-Sm antibody (OR = 2.719, 95% CI: 1.365-5.418, p = 0.004). The SLICC/ACR damage index was comparable in patients with and without anti-P antibodies (p = 0.780). Conclusions: The novel association of anti-P antibodies and autoimmune hemolytic anemia was evidenced in cSLE patients and further studies are necessary to determine if anti-P titers may vary with this hematological manifestation.
- 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.
- Disease presentation of 1312 childhood-onset systemic lupus erythematosus: influence of ethnicity(2019) FIOROT, Fernanda J.; ISLABAO, Aline G.; PEREIRA, Rosa M.; TERRERI, Maria T.; SAAD-MAGALHAES, Claudia; V, Glaucia Novak; MOLINARI, Beatriz C.; SAKAMOTO, Ana P.; AIKAWA, Nadia E.; CAMPOS, Lucia M.; PERACCHI, Octavio A.; APPENZELLER, Simone; FERRIANI, Virginia P.; SILVA, Marco F.; FONSECA, Adriana R.; SZTAJNBOK, Flavio R.; PAIM, Luciana B.; FRAGA, Melissa M.; OKUDA, Eunice M.; BICA, Blanca E.; SENA, Evaldo G.; MORAES, Ana J.; ROLIM, Ana M.; SPELLING, Paulo F.; SCHEIBEL, Iloite M.; CAVALCANTI, Andre S.; MATOS, Erica N.; ROBAZZI, Teresa C.; GUIMARAES, Luciano J.; SANTOS, Flavia P.; RAMOS, Valeria C.; CARNEIRO-SAMPAIO, Magda; BONFA, Eloisa; SILVA, Clovis A.Objective To evaluate the influence of ethnicity in presentation of childhood-onset systemic lupus erythematosus (cSLE) patients. Methods This multicenter study included cSLE patients (American College of Rheumatology criteria) followed in 27 Pediatric Rheumatology services of Brazil. Ethnicities were classified in four groups according to the parents' and all four grandparents' self-reported ethnicity. The statistical analysis was performed using the Bonferroni's correction (p < 0.0027). Results According to ethnic groups, 1537 cSLE patients were classified in Caucasian (n = 786), African-Latin American (n = 526), Asian (n = 8), and others/unknown (n = 217). Comparisons between 1312 African-Latin American and Caucasian revealed similar median age at cSLE diagnosis [12.2(2.6-18) vs. 12.1(0.3-18) years, p = 0.234], time interval to diagnosis [0.25(0-12) vs. 0.3(0-10) years, p = 0.034], and SLEDAI-2K score [14(0-55) vs. 14(0-63), p = 0.781] in both groups. The mean number of diagnostic criteria according to SLICC (6.47 +/- 1.911 vs. 5.81 +/- 1.631, p < 0.0001) and frequencies of maculopapular lupus rash (8% vs. 3%, p < 0.0001), palate oral ulcers (17% vs. 11%, p = 0.001), tongue oral ulcers (4% vs. 1%, p = 0.001), and nonscarring alopecia (29% vs. 16%, p < 0.0001) were significantly higher in African-Latin American, whereas malar rash (45% vs. 58%, p < 0.0001) was more frequent in Caucasian. The presence of anti-phospholipid antibody (23% vs. 12%, p < 0.0001), low complement levels (58% vs. 41%, p < 0.0001), and isolated direct Coombs test (10% vs. 5%, p = 0.001) was also significantly higher in the former group. Conclusions Our study demonstrated that disease presentation severity of African-Latin American cSLE patients is comparable with Caucasian. Mucocutaneous manifestations and autoantibodies profile were the only distinctive features of the former group. The unique mixed background of Brazilian patients probably minimized race diversity spectrum of these patients.
