- Hormone therapy effect on menopausal systemic lupus erythematosus patients: a systematic review(2022) SOARES-JR, J. M.; SORPRESO, I. C. Esposito; CURADO, J. F. Nunes; FERREIRA FILHO, E. S.; SIMOES, R. dos Santos; BONFA, E.; SILVA, C. A.; BARACAT, E. C.Systemic lupus erythematosus (SLE) primarily affects women, who may need hormone therapy (HT) in menopause. There is, however, some concern as to its efficacy and safety. This systematic review aimed to determine the effect of HT on the activity of SLE and its safety. The study was a qualitative systematic review. Research was conducted with data retrieved from Embase, MEDLINE and Cochrane databases using MESH terms up to April 2021, with no bar on date or language. Sixteen studies were selected for analysis. Most of them showed HT to be effective in the treatment of menopausal symptoms with no impact in SLE activity, but one randomized clinical trial showed an increase in the number of thrombotic events. The present systematic review demonstrated the efficacy of HT for treating the menopausal symptoms of SLE patients. The risk of flare and thrombosis seems to be very low.

Methods: Extraction included acetonitrile/water clean-up and online SPE. The LOD, LLOQ, linearity, precision, accuracy, recovery, matrix effect, process efficiency, carryover, stability, drug interference and dilution integrity were assessed. Results: The method was linear from 50 to 2000 ng/ml with a LOD of 20 ng/ml and LLOQ of 50 ng/ml. The coefficient of variation for precision was 0.4-7.9% for intra-assay and 1.3-8.9% for interassay and accuracy was 81.4-97.1%. Adequate matrix effect (100.6-107.0%), recovery (88.7-105.0%) and process efficiency (91.3-109.3%) were registered. DPS was stable for 14 days at room temperature and 45 degrees C and for 4 months at -80 degrees C. The method was applied to quantify THD in both wet plasma and DPS from patients with cutaneous lupus receiving THD treatment. The difference between THD wet plasma and DPS concentration was Conclusion: The method is suitable to quantify THD in DPS.
- Spotlight on latent tuberculosis infection screening for juvenile idiopathic arthritis in two countries, comparing high and low risk patients(2022) PIOTTO, Daniela; NICACIO, Aline; NETO, Agna; MOURAO, Ana Filipa; OLIVEIRA-RAMOS, Filipa; CAMPANILHO-MARQUES, Raquel; GUEDES, Margarida; CABRAL, Marta; SANTOS, Maria Jose; FONSECA, Joao Eurico; CANHAO, Helena; AIKAWA, Nadia Emi; OLIVEIRA, Sheila K. F.; FERRIANI, Virginia P. L.; PILEGGI, Gecilmara C. S.; MAGALHAES, Claudia S.; SILVA, Clovis Artur; TERRERI, Maria TeresaBackground Rheumatic diseases are associated with an increase in overall risks of tuberculosis (TB). The aim of this study was to evaluate the frequency of TB and the frequency of latent TB infection (LTBI), in clinical practice, for juvenile idiopathic arthritis (JIA) patients from high and low risk of TB incidence endemic countries. Methods This is an international, multicenter, cross-sectional, observational study of data collection from Brazil and Registry of Portugal at REUMA.PT. The inclusion criteria were patients with Juvenile Idiopathic Arthritis (JIA) with age <= 18 years who underwent screening for Mycobacterium tuberculosis infection [tuberculin skin test (TST) and/or interferon gamma release assay (IGRA)]. Chest X-rays and history of exposure to TB were also assessed. Results 292 JIA patients were included; mean age 14.3 years, mean disease duration 7.5 years, 194 patients (66.4%) performed only TST, 14 (4.8%) only IGRA and 84 (28.8%) both. The frequency of LTBI (10.6%) and TB was similar between the two countries. The reasons for TB screening were different; in Brazil it was performed more often at JIA onset while in Portugal it was performed when starting Disease Modified Anti-Rheumatic Drugs (DMARD) treatment (p < 0.001). Isoniazid therapy was prescribed in 40 (13.7%) patients (31 with LTBI and 9 with epidemiologic risks and/or due to contact with sick people). Only three patients (1%) developed active TB. Conclusion We found nearly 10% of patients with LTBI, a small percentage of patients with treatment due to epidemiologic risks and only 1% with active TB. Distinct reasons and screening methods for LTBI were observed between the two countries.
- Heart function in juvenile idiopathic arthritis patients: A biventricular two-dimensional speckle-tracking echocardiography study(2022) LIANZA, Alessandro C.; LEAL, Gabriela N.; AIKAWA, Nadia E.; KOZU, Katia T.; DINIZ, Maria De Fatima R.; SAWAMURA, Karen S. S.; MENEZES, Carolina R. B.; MARTINS, Camila Lino; CAMPOS, Lucia M.; ELIAS, Adriana M.; SILVA, Clovis A.Objectives We evaluated cardiac function in juvenile idiopathic arthritis (JIA) patients by 2D speckle-tracking echocardiography (2DSTE) and to assess possible associations with clinical, laboratorial, and treatment data. Methods A group of 42 JIA patients and 42 healthy controls were evaluated using both conventional echocardiography and 2DSTE. JIA patients underwent clinical and laboratory assessment. Results Conventional echocardiography data demonstrated normal left ventricular (LV) ejection fraction in both groups (71 vs. 71%; p = .69). 2DSTE analysis demonstrated that JIA patients presented significantly lower LV global systolic longitudinal strain (LVGLS) (-18.76 vs. -22%; p < .0001), LV systolic strain rate (LVSSR) (1.06 vs. 1.32 s(-1); p < .0001), LV diastolic strain rate (LVDSR) (1.58 vs. 1.8 s(-1); p < .0137), right ventricular global systolic strain (RVGLS) (-24.1% vs. -27.7%; p = .0002), and right ventricular systolic strain rate (RVSSR) (1.4 vs. 1.8 s(-1); p = .0035). JIA patients under biological agents presented higher LVGLS (p = .02) and RVLS (p = .01). We also detected an association between LVGLS and C-reactive protein [CRP; -20% in normal CRP (10/42) vs. -18% in elevated CRP patients (32/42), p = .03]. Conclusions JIA patients present different echocardiographic status from healthy patients. Moreover, our data suggest that JIA patients under biological agents present association with better cardiac function as shown by strain analysis.
- International Consensus for the Dosing of Corticosteroids in Childhood-Onset Systemic Lupus Erythematosus With Proliferative Lupus Nephritis(2022) CHALHOUB, Nathalie E.; WENDERFER, Scott E.; LEVY, Deborah M.; ROUSTER-STEVENS, Kelly; AGGARWAL, Amita; I, Sonia Savani; RUTH, Natasha M.; ARKACHAISRI, Thaschawee; QIU, Tingting; MERRITT, Angela; ONEL, Karen; GOILAV, Beatrice; KHUBCHANDANI, Raju P.; DENG, Jianghong; FONSECA, Adriana R.; ARDOIN, Stacy P.; CIURTIN, Coziana; KASAPCOPUR, Ozgur; JELUSIC, Marija; HUBER, Adam M.; OZEN, Seza; KLEIN-GITELMAN, Marisa S.; APPENZELLER, Simone; CAVALCANTI, Andre; FOTIS, Lampros; LIM, Sern Chin; SILVA, Rodrigo M.; RAMIREZ-MIRAMONTES, Julia; ROSENWASSER, Natalie L.; SAAD-MAGALHAES, Claudia; SCHONENBERG-MEINEMA, Dieneke; SCOTT, Christiaan; SILVA, Clovis A.; ENCISO, Sandra; TERRERI, Maria T.; TORRES-JIMENEZ, Alfonso-Ragnar; TRACHANA, Maria; AL-MAYOUF, Sulaiman M.; DEVARAJAN, Prasad; HUANG, Bin; I, Hermine BrunnerObjective To develop a standardized steroid dosing regimen (SSR) for physicians treating childhood-onset systemic lupus erythematosus (SLE) complicated by lupus nephritis (LN), using consensus formation methodology. Methods Parameters influencing corticosteroid (CS) dosing were identified (step 1). Data from children with proliferative LN were used to generate patient profiles (step 2). Physicians rated changes in renal and extrarenal childhood-onset SLE activity between 2 consecutive visits and proposed CS dosing (step 3). The SSR was developed using patient profile ratings (step 4), with refinements achieved in a physician focus group (step 5). A second type of patient profile describing the course of childhood-onset SLE for >= 4 months since kidney biopsy was rated to validate the SSR-recommended oral and intravenous (IV) CS dosages (step 6). Patient profile adjudication was based on majority ratings for both renal and extrarenal disease courses, and consensus level was set at 80%. Results Degree of proteinuria, estimated glomerular filtration rate, changes in renal and extrarenal disease activity, and time since kidney biopsy influenced CS dosing (steps 1 and 2). Considering these parameters in 5,056 patient profile ratings from 103 raters, and renal and extrarenal course definitions, CS dosing rules of the SSR were developed (steps 3-5). Validation of the SSR for up to 6 months post-kidney biopsy was achieved with 1,838 patient profile ratings from 60 raters who achieved consensus for oral and IV CS dosage in accordance with the SSR (step 6). Conclusion The SSR represents an international consensus on CS dosing for use in patients with childhood-onset SLE and proliferative LN. The SSR is anticipated to be used for clinical care and to standardize CS dosage during clinical trials.
conferenceObject EVALUATION OF BURNOUT SYNDROME IN PAEDIATRIC INTENSIVE CARE UNIT DURING COVID-19 PANDEMIC(2022) RODRIGUEZ, I. S.; CARLOTTI, A. D.; GOES, P. F.; ARAGON, D. C.; JOHNSTON, C.; SILVA, C. A.; CARVALHO, W. B.; DELGADO, A. F.- Idiopathic musculoskeletal pain, musculoskeletal pain syndromes, and use of electronic devices in adolescents with asthma(2022) NASTRI, Mariana Machado Forti; LOURENCO, Benito; QUEIROZ, Ligia Bruni; SILVA, Luiz Eduardo Vargas da; LOURENCO, Daniela Mencaroni Rodrigues; CASTRO, Ana Paula Beltran Moschione; SILVA, Clovis Artur; PASTORINO, Antonio CarlosObjective: To evaluate idiopathic musculoskeletal pain, musculoskeletal pain syndromes, and use of electronic devices in adolescents with asthma and healthy controls. Methods: Cross-sectional study was conducted on 150 asthmatic adolescents and 300 controls. Adolescents completed a self-administered questionnaire regarding painful symptoms, use of electronic devices, and physical activity. Seven musculoskeletal pain syndromes were evaluated, and Asthma Control Test (ACT) was assessed. Results: Musculoskeletal pain (42% vs. 61%, p = 0.0002) and musculoskeletal pain syndromes (2.7% vs. 15.7%, p = 0.0006) were significantly lower in asthmatic adolescents than in controls. The frequency of pain in the hands and wrists was reduced in asthmatic than in controls (12.6% vs. 31.1%, p = 0.004), in addition to cell phone use (80% vs. 93%, p < 0.0001), simultaneous use of at least two electronic media (47% vs. 91%, p < 0.0001), myofascial syndrome (0% vs. 7.1%, p = 0.043), and tendinitis (0% vs. 9.2%, p = 0.008). Logistic regression analysis, including asthma with musculoskeletal pain as the dependent variable, and female sex, ACT > 20, simultaneous use of at least two electronic devices, cell phone use, and weekends and weekdays of cell phone use, as independent variables, showed that female sex (odds ratio [OR], 2.06; 95% confidence interval [CI], 1.929-6.316; p = 0.0009) and ACT >= 20 (OR, 0.194; 95% CI, 0.039-0.967; p = 0.045) were associated with asthma and musculoskeletal pain (Nagelkerke R-2 = 0.206). Conclusions: Musculoskeletal pain and musculoskeletal pain syndromes were lower in adolescents with asthma. Female sex was associated with musculoskeletal pain in asthmatic, whereas patients with asthma symptoms and well-controlled disease reported a lower prevalence of musculoskeletal pain.

- 2019-EULAR/ACR classification criteria domains at diagnosis: predictive factors of long-term damage in systemic lupus erythematosus(2022) INSFRAN, Carlos E.; AIKAWA, Nadia E.; PASOTO, Sandra G.; FILHO, Dilson M. N.; FORMIGA, Francisco F. C.; PITTA, Ana C.; BORBA, Eduardo F.; RIBEIRO, Carolina T.; SILVA, Clovis A.; BONFA, EloisaThe objective of this study is to assess the role of the 2019-European League Against Rheumatism/American College of Rheumatology (2019-EULAR/ACR) classification criteria at diagnosis and its domains in predicting long-term damage in systemic lupus erythematosus(SLE). We performed a retrospective analysis using an electronic chart database utilized in routine clinical care of SLE patients and established in 2000 in a tertiary hospital. Two hundred and nine consecutive SLE patients with disease onset >= 18 years old and long disease duration were included. Cumulative damage at the last visit was scored using the SLICC/ACR-Damage Index (SDI). The median age at SLE diagnosis was 28 years (18-63), disease duration was 14 years (8-25), and 88% were females. Damage (SDI >= 1) was observed in 116/209 (55%). Patients with (SDI >= 1, n=116) and without damage (SDI=0, n=93) had similar median disease duration [14 (8-25) vs. 12 (8-25) years, p=0.090[ and age at diagnosis [23 (18-55) vs. 23 (18-56) years, p=0.998[. No correlation was observed between total 2019-EULAR/ACR score at diagnosis and SDI at last visit (r=0.007, p=0.913). Presence of renal domain at diagnosis was associated with renal damage at last visit (OR=3.6, 95%CI 1.2-10.4, p=0.017) and antiphospholipid antibodies domain predicted neuropsychiatric damage (OR=3.0, 95%CI 1.2-7.6, p=0.015). A ROC analysis identified that a cut-off >24 in 2019-EULAR/ACR score could predict a trend for renal damage (p=0.077) with a lower renal survival (Kaplan-Meier curve) for patients above this limit (p=0.029). A multivariate logistic regression analysis revealed that 2019-EULAR/ACR score >24 at diagnosis (OR 4.583, 95%CI 1.052-19.962, p=0.043) was independently associated with renal damage. Specific domains in the 2019-EULAR/ACR criteria at diagnosis were associated with long-term organspecific damage, particularly renal and neuropsychiatric harm. A 2019-EULAR/ACR score >24 predicted worse renal survival.
- Intermittent abdominal pain in IgA vasculitis(2022) BUSCATTI, Izabel Mantovani; SIMON, Juliana Russo; VIANA, Vivianne Saraiva Leitao; ARABI, Tamima Mohamad Abou; TRINDADE, Vitor Cavalcanti; MAIA, Ana Carolina Cortez; MELO, Lara Regina Cavalcante; IHARA, Bianca Pires; AIKAWA, Nadia Emi; SILVA, Clovis ArturObjective: To assess intermittent abdominal pain in IgA vasculitis patients and its relation to demographic data, clinical manifestations and treatments. Methods: A retrospective cohort study included 322 patients with IgA vasculitis (EULAR/PRINTO/PRES criteria) seen at the Pediatric Rheumatology Unit in the last 32 years. Sixteen patients were excluded due to incomplete data in medical charts. Intermittent abdominal pain was characterized by new abdominal pain after complete resolution in the first month of disease. Results: Intermittent abdominal pain was observed in 35/306 (11%) IgA vasculitis patients. The median time between first and second abdominal pain was 10 days (3-30 days). The main treatment of intermittent abdominal pain included glucocorticoid [n=26/35 (74%)] and/or ranitidine [n=22/35 (63%)]. Additional analysis showed that the frequency of intermittent purpura/petechiae (37 vs. 21%; p=0.027) and the median of purpura/petechiae duration [20 (3-90) vs. 14 (1-270) days; p=0.014] were significantly higher in IgA vasculitis patients with intermittent abdominal pain compared to those without. Gastrointestinal bleeding (49 vs. 13%; p<0.001), nephritis (71 vs. 45%; p=0.006), glucocorticoid (74 vs. 44%; p=0.001) and intravenous immunoglobulin use (6 vs. 0%; p=0.036) were also significantly higher in the former group. The frequency of ranitidine use was significantly higher in IgA vasculitis patients with intermittent abdominal pain versus without (63 vs. 28%; p<0.001), whereas the median of ranitidine duration was reduced in the former group [35 (2-90) vs. 60 (5-425) days; p=0.004]. Conclusions:Intermittent abdominal pain occurred in nearly a tenth of IgA vasculitis patients, in the first 30 days of disease, and was associated with other severe clinical features. Therefore, this study suggests that these patients should be followed strictly with clinical and laboratorial assessment, particularly during the first month of disease course.
- Nonsexual violence against children and adolescents: a study in a Latin American tertiary and university hospital(2022) CAMPOS, Reinan Tavares; MARTINIANO, Lorena Vasconcelos Mesquita; LIRIO, Amanda Kerlyn Santos; SOUZA, Kalesa Elias de Araujo; ROSE, Natalia; DIAS, Juliana Martins Monteiro; FARHAT, Sylvia Costa; SILVA, Clovis ArturObjective:The objective of this study was to assess interpersonal nonsexual violence against children and adolescents in a tertiary university hospital. Methods: A cross-sectional study was performed in 240 patients under nonsexual violence situation for 15 consecutive years. Data analyses included demographic data, hospital referral site, type and author of nonsexual violence, legal referral, laboratorial and imaging examinations, and outcomes.Results: Nonsexual violence situation was diagnosed in 240 (0.1%) of 295,993 patients for 15 years: 148 (61.7%) in children and 92 (38.3%) in adolescents. Out of 240, the most frequent types of violence were negligence in 156 (65.0%), physical 62 (25.8%), psychological/emotional aggression 52 (21.7%), Munchausen by proxy syndrome 4 (1.7%), and bullying/cyberbullying in 3 (1.3%). Out of 123, the most common pediatric chronic conditions were chronic kidney disease 24 (19.5%), human immunodeficiency virus 14 (11.4%), prematurity 9 (7.3%), cerebral palsy 8 (6.5%), and asthma 8 (6.5%). Further comparison between children versusadolescent under nonsexual violence situation revealed significant difference between the hospital referral sites. The frequency of patients under violence referred from outpatient clinics was significantly reduced in children versus adolescents (27.7 vs. 62%), whereas emergency department was higher in the former group (57.4 vs. 25.0%; p<0.001). All types of violence situations and pediatric chronic conditions were similar in both groups (p>0.05).Conclusions: Nonsexual violence against our pediatric population was rarely diagnosed in a tertiary hospital, mainly negligence, physical, and psychological/emotional aggression. Approximately two-thirds of violence diagnosis occurred in children, referred mainly by the emergency department. In contrast, approximately one-third of violence diagnosis occurred in adolescents, referred mostly by outpatient clinics.
