    Munchausen by proxy syndrome mimicking childhood-onset systemic lupus erythematosus
    (2019) KUHNE, A. C. A.; PITTA, A. C.; GALASSI, S. C.; GONCALVES, A. M. F.; CARDOSO, A. C. A.; PAZ, J. A.; CAMPOS, L. M. A.; SILVA, C. A.
    Childhood-onset systemic lupus erythematosus (cSLE) is a chronic inflammatory multisystem autoimmune disease that requires multiple differential diagnoses. Munchausen by proxy syndrome (MBPS) is a form of child abuse, where a caregiver intentionally creates a medical history and induces or fabricates signs or disease in a patient. To our knowledge, there is no case report of MBPS mimicking cSLE diagnosis. We reported herein a 9-year-old male patient, with a history of multiple hospitalizations due to seizures with altered levels of consciousness. The mother reported malar rash, photosensitivity, alopecia, arthralgia, arterial hypertension, macroscopic hematuria, seizure and positive antinuclear antibodies. In the other service, he was treated with intravenous methylprednisolone, prednisone and mycophenolate mofetil. At 8 years and 8 months, he was admitted to our tertiary center with history of fever and macroscopic hematuria. Laboratory examinations were normal, including negative for antinuclear antibodies, anti-double stranded DNA, anticardiolipin, anti-Ro/SSA, anti-La/SSB, anti-RNP and anti-Sm antibodies. Multiple urine cultures revealed the presence of Enterococcus faecium, Acinetobacter sp., Stenotrophomonas maltophilia and Serratia marcescens, without any association with pyuria. At 8 years and 9 months, he was readmitted at emergency room with history of severe fever, headache, vomiting, photophobia, phonophobia and dizziness. The physical examination showed agitation, confusion, ataxic gait, slurred speech, horizontal nystagmus, painful facial expressions, tachycardia and weight loss. Brain magnetic resonance angiography and cerebrospinal fluid analysis were normal. During hospitalization, he had an acute episode of epistaxis and otalgia with excoriation in the auditory canal. At that moment, the suspicion of MBPS mimicking cSLE was raised and phenytoin intoxication was confirmed (peak phenytoin concentration was 45.4 mcg/mL, therapeutic range 10-20 mcg/mL). The mother and the patient were immediately separated, and she was replaced by another legal guardian. One week later, the neurological and other signs and symptoms were completely resolved. The child was placed under paternal custody with a court order and moved to another state. After that, the mother reported phenytoin use for her child and was referred to psychiatric follow-up. In conclusion, the first case of MBPS mimicking cSLE, resulting in multiple unnecessary examinations and treatments with delayed diagnosis was reported.

    Acute petrified myocardium associated with meningococcal sepsis in childhood-onset systemic lupus erythematous: a fatal case
    (2019) SANTOS, Ana Carolina Etrusco Zaroni; LUGLIO, Michele; DELGADO, Artur Figueiredo; SCHUWARTZ, Constance Dell Santo Vieira; MARQUES, Heloisa Helena Sousa; VALOES, Clarissa Carvalho de Miranda; DOMINGUEZ, Maria Andreina Cabrera; CARVALHO, Werther Brunow de; SILVA, Clovis Artur; DUARTE-NETO, Amaro Nunes
    Acute petrified myocardium associated with septic shock, diagnosed by autopsy has rarely been described. A 15-year-old adolescent male was diagnosed with childhood-onset systemic lupus erythematosus. One year later, he was hospitalized with fever, myalgia, headache, arthritis, vomiting, dyspnea and was diagnosed with sepsis secondary to bronchopneumonia and meningitis. Blood culture identified Neisseria meningitidis serogroup Y. Despite antibiotics and intensive therapeutic measures, he died after 29 days of hospitalization. The autopsy revealed necrotic cardiomyocytes with dystrophic calcification and interstitial fibrosis.

    (2019) PITTA, Ana Claudia; FERREIRA, Gabriela Ribeiro Viola; TOMIOKA, Renato Bussadori; LOURENCO, Daniela Mencaroni Rodrigues; KOZU, Katia; AIKAWA, Nadia Emi; SALLUM, Adriana Maluf Elias; CAMPOS, Lucia Maria Arruda; ABDO, Carmita Helena Najjar; PEREIRA, Rosa Maria Rodrigues; BARACAT, Edmund Chada; BONFA, Eloisa; SILVA, Clovis Artur
    Objective: To evaluate sexual function female adolescents and young adults with juvenile idiopathic arthritis (JIA) and healthy controls. Methods: After exclusion, 21 female adolescent and young JIA patients and 25 healthy controls were selected for this study. Sexual function was assessed by the Sexual Quotient Questionnaire for Females (SQQ-F) score, which is a validated tool and adapted for Brazilian Portuguese language. Demographic data, JIA clinical/laboratory parameters and treatment were also assessed. Results: The median current age [26.5 (17-38.1) vs. 29.3 (19.7-35.8) years, p = 0.700)] as well as age at the first sexual activity [18 (14-30) vs. 17 (10-24) years, p = 0.158] were similar in JIA patients and healthy controls. The median of SQQF score was alike in both groups [75.9 (50-92) vs. 78.2 (58-94), p = 0.529], as well as frequencies of sexual dysfunction (14% vs. 12%, p = 1.000). The frequencies of all sexual domains (desire/sexual fantasies, desire/interest, arousal/foreplay, arousal/lubrication, arousal/in tune with partner, penetration/relaxation, pain/penetration, desire/involvement, orgasm and general satisfaction scores) were similar in JIA patients and healthy controls (p > 0.05). Conclusions: To our knowledge, this was the first study using a validated sexual score in a chronic arthritis population suggesting a low frequency of overall sexual dysfunction in young JIA patients. Future multicenter studies with a large sample will be necessary to confirm this finding.

    Development and initial validation of the MS score for diagnosis of macrophage activation syndrome in systemic juvenile idiopathic arthritis
    (2019) MINOIA, Francesca; BOVIS, Francesca; DAVI, Sergio; HORNE, AnnaCarin; FISCHBACH, Michel; FROSCH, Michael; HUBER, Adam; JELUSIC, Marija; SAWHNEY, Sujata; MCCURDY, Deborah K.; SILVA, Clovis A.; RIGANTE, Donato; UNSAL, Erbil; RUPERTO, Nicolino; MARTINI, Alberto; CRON, Randy Q.; RAVELLI, Angelo
    Objective To develop and validate a diagnostic score that aids in identifying macrophage activation syndrome (MAS) in patients with systemic juvenile idiopathic arthritis (sJIA). Methods The clinical and laboratory features of 362 patients with sJIA-associated MAS and 404 patients with active sJIA without evidence of MAS were collected in a multinational collaborative project. Eighty percent of the study population was used to develop the score and the remaining 20% constituted the validation sample. A Bayesian Model Averaging approach was used to assess the role of each clinical and laboratory variables in the diagnosis of MAS and to obtain the coefficients of selected variables. The final score, named MAS/sJIA (MS) score, resulted from the linear combination of these coefficients multiplied by the values of each variable. The cut-off that best discriminated MAS from active sJIA was calculated by means of receiver operating characteristic (ROC) curve analysis. Score performance was evaluated in both developmental and validation samples. Results The MS score ranges from -8.4 to 41.8 and comprises seven variables: central nervous system dysfunction, haemorrhagic manifestations, active arthritis, platelet count, fibrinogen, lactate dehydrogenase and ferritin. A cut-off value >=-2.1 revealed the best performance in discriminating MAS from active sJIA, with a sensitivity of 0.85, a specificity of 0.95 and a kappa value of 0.80. The good performance of the MS score was confirmed in the validation sample. Conclusion The MS score is a powerful and feasible tool that may assist practitioners in making a timely diagnosis of MAS in patients with sJIA.

    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.
