conferenceObject Poor Physical Activity Levels and Cardiorespiratory Fitness Among Patients with Childhood-Onset Takayasu Arteritis in Remission(2020) ASTLEY, Camilla; GIL, Saulo; CLEMENTE, Gleice; TERRERI, Maria Teresa; CAMPOS, Lucia; AIKAWA, Nadia; PINTO, Ana Lucia de-Sa; PEREIRA, Rosa; ROSCHEL, Hamilton; GUALANO, Bruno- Childhood-onset systemic lupus erythematosus-related antiphospholipid syndrome: A multicenter study with 1519 patients(2020) ISLABA, Aline G.; MOTA, Licia M. H.; RIBEIRO, Maria Custodia M.; ARABI, Tamima M.; CIVIDATTI, Georgiana N.; QUEIROZ, Ligia B.; ANDRADE, Danieli C.; SAKAMOTO, Ana P.; TRINDADE, Vitor C.; NOVAK, Glaucia V.; MOLINARI, Beatriz C.; CAMPOS, Lucia M.; AIKAWA, Nadia E.; PEREIRA, Rosa M. R.; TERRERI, Maria T.; MAGALHA, Claudia S.; MARINI, Roberto; GOMES, Hugo R.; SILVA, Marco F.; OLIVEIRA, Sheila K.; SZTAJNBOK, Flavio R.; SACCHETTI, Silvana B.; BICA, Blanca E.; SENA, Evaldo G.; MORAES, Ana P.; SANTOS, Maria C.; ROBAZZI, Teresa C.; SPELLING, Paulo F.; SCHEIBEL, Iloite M.; CAVALCANTI, Andre S.; NAKA, Erica N.; GUIMARAES, Luciano J.; SANTOS, Flavia P.; SAMPAIO, Magda C.; BONFA, Eloisa; SILVA, Clovis A.Objective: To assess childhood-onset systemic lupus erythematosus-related antiphospholipid syndrome(cSLE-APS) in a large Brazilian population. Methods: A retrospective observational cohort study was carried-out in 27 Pediatric Rheumatology university centers, including 1519 cSLE patients. Results: cSLE-APS was observed in 67/1519 (4%) and was diagnosed at disease onset in 39/67 (58%). The median disease duration was 4.9 (0-17) years. Thrombosis recurrences were evidenced in 18/67 (27%) cSLE-APS patients. The most frequent thrombosis sites in cSLE-APS patients were: venous thrombosis in 40/67 (60%), especially deep vein thrombosis in 29/40 (72%); arterial thrombosis in 35/67 (52%), particularly stroke; small vessels thrombosis in 9/67 (13%) and mixed thrombosis in 3/67 (4%). Pregnancy morbidity was observed in 1/67 (1%). Non-thrombotic manifestation associated to cSLE-APS occurred in 21/67 (31%), mainly livedo reticularis in 14/67 (21%), valvar thickening in 4/67 (6%) and valvar vegetations not related to infections in 2/67 (3%). None of them had catastrophic APS. Further analysis demonstrated that the median of SLICC/ACR-DI [1 (0-5) vs. 0(0-7),p < 0.0001] was significantly higher in cSLE-APS patients compared to cSLE without APS. The frequencies of cerebrovascular disease (40% vs. 1%,p < 0.0001), polyneuropathy (9% vs. 1%,p < 0.0001), SLICC/ACR-DI >= 1 (57% vs. 27%, p < 0.0001) and intravenous cyclophosphamide use (59% vs. 37%, p < 0.0001) were significantly higher in the former group. Conclusions: Our large multicenter study demonstrated that cSLE-APS was a rare condition, occurring during disease course with a high accrual damage. Central and peripheral neuropsychiatric involvements were distinctive features of this autoimmune thrombosis.
- Improvement of conjunctival cytological grade and tear production in Ankylosing Spondylitis patients under TNF inhibitors: a long-term follow-up(2020) USUBA, Fany Solange; SAAD, Carla Goncalves Schahin; AIKAWA, Nadia Emi; NOVAES, Priscila; MORAES, Julio Cesar Bertacini; SANTO, Ruth Miyuki; CARVALHO, Jozelio Freire; BONFA, Eloisa; ALVES, Milton RuizDry eye disease can compromise the patient's quality of life. Few studies assessed the ocular surface (OS) in Ankylosing Spondylitis (AS) patients. This study aimed to evaluate the clinical and cytological findings of the OS in patients with AS, classify dry eye disease (DED) severity grade and conjunctival impression cytology (IC), and the effects of TNF inhibitors (TNFi) in a one-year follow-up. A baseline (BL) evaluation included 36 AS patients and 39 healthy controls. They fulfilled the Ocular Surface Index Disease questionnaire and underwent the Schirmer I test, break-up time, vital staining, and conjunctival IC. A DED severity grade, as well as IC rating, was applied. Fourteen of these patients received TNFi and analysis of ocular and systemic AS disease parameters occurred at BL and three months (3 M), and 12 months (12 M) after treatment. The AS patients presented a higher frequency of DED (p = 0.01), a worse score of severity (p = 0.001), and a higher frequency of altered IC (p = 0.007) when compared to controls. The 14 patients under TNFi presented an improvement in all the clinical disease activity parameters throughout the one-year treatment (p < 0.05) even as a concomitant increase in the Schirmer test (p = 0.04), and a significant amelioration in the altered IC to a normal IC (p = 0.006). DED is a frequent and under-diagnosed ocular disease in AS patients. The long-term parallel improvement of disease activity and OS parameters in AS patients receiving TNFi suggests that the OS can be an additional target of systemic inflammation in AS.
- Dry eye in rheumatoid arthritis patients under TNF-inhibitors: conjunctival goblet cell as an early ocular biomarker(2020) USUBA, Fany Solange; MEDEIROS-RIBEIRO, Ana Cristina de; NOVAES, Priscila; AIKAWA, Nadia Emi; BONFIGLIOLI, Karina; SANTO, Ruth Miyuki; BONFA, Eloisa; ALVES, Milton RuizDry eye disease (DED) is common in Rheumatoid Arthritis ( RA) patients. The application of conjunctival goblet cell count as a clinical biomarker to diagnose and respond to treatment can take place in rheumatoid arthritis patients under TNF-inhibitors (TNFi) therapy. This study aimed to investigate the ocular surface parameters and the long-term effects of TNFi therapy on ocular surface features and goblet cell count of rheumatoid arthritis patients. At baseline, rheumatoid arthritis patients eligible to TNFi were compared to healthy controls (similar age/gender), regarding Ocular Surface Disease Index (OSDI) questionnaire, Schirmer I test, tear break-up time test, vital dye staining of the ocular surface, and conjunctival impression cytology. DED severity grade, impression cytology score, and goblet cell count were analyzed. Rheumatoid arthritis patients were followed after three (3 M) and 12 months (12 M), during TNFi treatment. Sixteen rheumatoid arthritis patients and 24 controls were compared: a higher frequency of abnormal OSDI (68.8% vs. 16.7%, p = 0.002), Schirmer's test < 10 mm (37.5% vs. 8.3%, p = 0.042), meibomian gland dysfunction (50% vs. 8.3%, p = 0.007), abnormal impression cytology (75% vs. 8.3%, p < 0.001), and mild to moderate DED (81.3% vs. 4.2%, p < 0.001) were observed in rheumatoid arthritis patients, who also had lower goblet cell count [325 (274-707) cells/mm(2) vs. 742 (562-863) cells/mm(2), p = 0.004]. The presence of Meibomian gland dysfunction was associated with higher disease activity scores (p < 0.05). The prospective early observation of these patients at 3 M showed an increase improvement in tear production by Schirmer's test [13 (7.5-17.5) vs. 23.5 (16-35); p = 0.001], and an improvement in impression cytology score [1 (0.5-2) vs. 1 (0-1), p = 0.031] and in goblet cell count [325 (274-707) vs. 931 (656-1,244), p < 0.001]. Eight RA responders to TNFi were also re-evaluated at 12 M with further improvement in goblet cell count [393 (275-827) vs. 872 (502-1,185) vs. 1,079 (867-1,244), p = 0.047]. Multifactorial DED is frequent in RA patients, comprising aqueous, lipid, and mucin components. TNFi prompt improves tear production and recovers the goblet cells, which can be a biomarker of the pathological process and response to therapy in this population.
- Anti-adalimumab antibodies kinetics: an early guide for juvenile idiopathic arthritis (JIA) switching(2020) BRUNELLI, Juliana Barbosa; SILVA, Clovis Almeida; PASOTO, Sandra Gofinet; SAA, Carla Goncalves Schahin; KOZU, Katia Tomie; GOLDENSTEIN-SCHAINBERG, Claudia; LEON, Elaine Pires; VENDRAMINI, Margarete B. G.; FONTOURA, Nicole; BONFA, Eloisa; AIKAWA, Nadia EmiObjective To assess the longitudinal production of anti-adalimumab antibody (AAA) and baseline risk factors for this antibody development in juvenile idiopathic arthritis (JIA) patients initiating adalimumab (ADA). Method Thirty consecutive JIA patients under ADA therapy were prospectively followed. JIA clinical/laboratorial/treatment data and sera for ADA and AAA assays (ELISA and bridging ELISA) were obtained at baseline (BL), 2 months (2M), 3 months (3M), 6 months (6M), 12 months (12M), and 24 months (24M). Patients with therapy failure requiring ADA withdrawn had their sera evaluated at their last medical visit prior to biologic switch (blinded to ADA and AAA levels). Results AAA was absent at BL, first detected at 2M after ADA initiation in 2/30 (7%) patients with a significant increase at 3M (10/29 (34%), p = 0.013) and no major change in 6M (11/30 (37%)) and 12M (9/26 (35%)). Of note, at 3M, AAA levels correlated negatively with ADA levels (r = - 0.781, p = 0.0001). Analysis of BL predictors revealed a significantly higher risk of developing AAA in patients with female gender (OR 21; 95% CI 1.08-406.57; p = 0.044), ESR > 30 mm/1st hour (OR 5.44; 95% CI 1.04-28.53; p = 0.045), and leflunomide use (OR 9.33; 95% CI 1.51-57.66; p = 0.016). In contrast, concomitant use of methotrexate was protective for AAA appearance (OR 0.08; 95% CI 0.01-0.53; p = 0.009). After 12M of ADA, 60% of AAA-positive patients required drug switch for drug failure compared with 15% in AAA-negative group (p = 0.03). Conclusions This study provides novel evidence of AAA production kinetics demonstrating a timely significant increase starting at 3M and stable throughout 24M. We also identified female gender, increased ESR, and leflunomide use as relevant risk factors for AAA production at BL, whereas methotrexate was protective. Early systematic monitoring of AAA at 3M may, therefore, guide drug switching in these patients.
conferenceObject Is Positron Emission Tomography/Magnetic Resonance Imaging (PET/MRI) a Reliable Tool for Detecting Vascular Activity in Treated Childhood-Onset Takayasu's Arteritis (C-TA)? A Multicenter Study(2020) RUSSO, Gleice; PEREIRA, Rosa; AIKAWA, Nadia; SILVA, Clovis; CAMPOS, Lucia; SAKAMOTO, Ana Paula; SOUZA, Alexandre; TERRERI, Maria Teresa- Safety and immunogenicity of the quadrivalent human papillomavirus vaccine in patients with juvenile dermatomyositis: a real-world multicentre study(2020) GREIN, Ingrid Herta Rotstein; PINTO, Natalia Balera Ferreira; GROOT, Noortje; MARTINS, Camila Bertini; LOBO, Aline; AIKAWA, Nadia Emi; BARBOSA, Cassia; TERRERI, Maria Teresa; FRAGA, Aline Coelho Moreira da; OLIVEIRA, Sheila Knupp Feitosa de; SZTAJNBOK, Flavio; MARQUES, Luciana B. Paim; ISLABAO, Aline Garcia; APPENZELLER, Simone; BICA, Blanca; SATO, Juliana de Oliveira; MAGALHAES, Claudia Saad; FERRIANI, Virginia; PASMANS, Hella; SCHEPP, Rutger; KLIS, Fiona van der; ROOCK, Sytze de; WULFFRAAT, Nico; PILEGGI, Gecilmara SalviatoBackground: Concerns about the safety and efficacy of vaccines in patients with autoimmune diseases (AID) have led to contradictions and low vaccination coverage in this population, who are at a higher risk of infections, including by human papillomavirus (HPV). Although HPV vaccines have been recommended for immunocompromised patients, there is still a lack of data to support its use for AID patients, such as juvenile dermatomyositis (JDM) patients. The aim of this study was to assess the safety and immunogenicity of the quadrivalent HPV (qHPV) vaccine in a cohort of JDM patients. Methods: JDM patients aged from 9 to 20 years and healthy controls (HC) were enrolled to receive a 3-dose schedule of qHPV vaccine from March/2014 to March/2016. Study visits were performed before the first dose, 1 month after the second and third doses, and 6 months after the third dose. Participants completed a diary of possible adverse events for 14 days following each dose of vaccination (AEFV). Disease activity and current therapy were analyzed at each visit for JDM patients. In addition, serum samples from all participants were collected to test antibody concentrations against HPV16 and 18 at each visit. Participant recruitment was conducted in ten Brazilian centres. From 47 eligible JDM patients and 41 HC, 42 and 35, respectively, completed the 3-dose schedule of the vaccine, given that five JDM patients and two HC had received doses prior to their inclusion in the study. Results: The AEFVs presented by the participants were mild and in general did not differ between JDM and HC groups. No severe AEFVs were related to the vaccination. Disease activity was stable, or even improved during the follow-up. One month after the third dose of the vaccine the JDM group presented seropositivity of 100% for HPV16 and 97% for HPV18, similarly to the HC group, who presented 100% for both serotypes (p = 1.000). Six months after the third dose the seropositivity for the patient group was 94% for both HPV types. Conclusions: The HPV vaccination in this cohort of JDM patients was safe and immunogenic. Since the seropositivity against HPV16 and 18 was very high after the 3-dose schedule, this regimen should be recommended for JDM patients.
- Understanding the dynamics of hydroxychloroquine blood levels in lupus nephritis(2020) PEDROSA, Tatiana N.; PASOTO, Sandra G.; AIKAWA, Nadia E.; YUKI, Emily F. N.; BORBA, Eduardo F.; FERREIRA FILHO, Julio C. R.; CARRICONDO, Pedro C.; ZANETTI, Caio B.; CONDE, Paola G.; DUARTE, Nilo J. C.; FONTOURA, Nicole; ROMANO, Paschoalina; CARVALHO, Valdemir M.; SILVA, Clovis A.; BONFA, EloisaObjectives It is unknown if hydroxychloroquine blood level dynamics impact flare rates in lupus nephritis patients. We prospectively evaluated hydroxychloroquine levels to determine which blood-based patterns are more associated with disease activity. Methods In total, 82 lupus nephritis patients under a prescribed hydroxychloroquine dose of 4-5.5 mg/kg actual body weight (maximum 400 mg/day) for >= 3 months were evaluated at baseline and 7 months. Hydroxychloroquine blood levels were determined by liquid chromatography-tandem mass spectrometry. Flare was defined as increase >= 3 in the Systemic Lupus Erythematosus Disease Activity Index 2000 score and/or a change or increase in therapy. Results Overall, 9/82(11%) patients had flares during follow-up and had lower baseline hydroxychloroquine blood levels than those without flares (220.4 (53.5-1471.1) vs. 1006.3 (53.5-2137.8) ng/ml, p = 0.013). The hydroxychloroquine blood level cut-off that best predicted flares was 613.5 ng/ml (odds ratio = 8.67, 95% confidence interval: 1.66-45.18, p = 0.006). For 77 (94%) patients, the 7-month hydroxychloroquine level dynamics was evaluated and revealed: 59/77 (77%) had a persistent pattern of adequate (41/77(53%)) or fluctuating (18/77 (23%)) levels, with a low and comparable risk of flares (2/41 (5%) vs. 1/18 (5%), p = 1.000). The remaining group had persistent low levels (18/77 (23%)) and their flare frequency was significantly higher than the adequate group (5/18 (28%) vs. 2/41 (5%), p = 0.023). The frequencies of adequate/inadequate hydroxychloroquine blood levels in patients were comparable at baseline and 7 months (McNemar's test, p = 0.480). Conclusion We provide novel evidence that hydroxychloroquine blood-level patterns (persistently low, adequate, or intermittent) have distinct impacts on flare rates in lupus nephritis patients. These findings reinforce the need of routine hydroxychloroquine measurements to maintain the appropriate blood levels.
