Impact of COVID-19 on physical and mental functioning in adolescents with disabilities in a sports nongovernmental organization / Impacto da COVID-19 no funcionamento físico e mental de adolescentes com deficiência em organização não governamental esportiva

Abstract Objective: This study aimed to assess physical and mental health, and health-related quality of life (HRQL) parameters in adolescents with physical disabilities enrolled in a sports nongovernmental organization (NGO) versus adolescents without disabilities during coronavirus disease 2019 (COVID-19) pandemic. Methods: This cross-sectional study included 30 adolescents with disabilities and 86 adolescents without disabilities who responded to an online questionnaire with sociodemographic data and self-rated healthcare routine information during the COVID-19 quarantine. Validated self-report versions of the Strengths and Difficulties Questionnaire (SDQ), Pediatric Quality of Life Inventory 4.0 (PedsQL 4.0), Pittsburgh Sleep Quality Index (PSQI), and Pediatric Outcome Data Collection Instrument (PODCI) were also applied. Results: The median of emotional [4 (0-10) vs. 5 (0-10), p=0.018] and prosocial [7 (0-10) vs. 9 (3-10), p=0.006] problems was lower in adolescents with disabilities versus adolescents without disabilities. Adolescents with disabilities had significantly lower global function [68 (21-99) vs. 94 (67-100), p<0.001] and higher happiness scores in the PODCI scale [90 (65-100) vs. 80 (0-100), p=0.016] compared to controls. Logistic regression analysis demonstrated that physical activity/week (OR=1.03; 95%CI 1.01-1.05, p=0.002) was higher in adolescents with disabilities compared to adolescents without disabilities. However, housework activities (OR=0.14; 95%CI 0.04-0.43, p=0.001) and screen time ≥3 h/day (OR=0.09; 95%CI 0.02-0.38, p=0.001) were lower in adolescents with disabilities compared to adolescents without disabilities. Conclusion: Adolescents with disabilities attending a sports NGO were not at higher risk of adverse health-related indicators; despite showing reduced physical function, they reported more physical activity, higher happiness, and less screen time compared to adolescents without disabilities during the COVID-19 pandemic.

Resumo Objetivo: Avaliar os parâmetros de saúde física e mental, de qualidade de vida relacionada à saúde (QVRS), em adolescentes com deficiência física matriculados em organização não governamental (ONG) esportiva vs. em adolescentes sem deficiência, durante a pandemia da doença do coronavírus 2019 (COVID-19). Métodos: Este estudo transversal incluiu 30 adolescentes com deficiência e 86 adolescentes sem deficiência que responderam a questionário online com dados sociodemográficos e informações de rotina de saúde autoavaliadas durante a quarentena da COVID-19. Versões validadas de autorrelato do Strengths and Difficulties Questionnaire (SDQ), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0), Pittsburgh Sleep Quality Index (PSQI) e Pediatric Outcome Data Collection Instrument (PODCI) também foram aplicadas. Resultados: A mediana de problemas emocionais [4(0-10) vs. 5(0-10),p=0,018] e pró-social [7(0-10) vs. 9(3-10),p=0,006] foi menor em adolescentes com deficiência vs. adolescentes sem deficiência. Adolescentes com deficiência tiveram função global significantemente inferior [68(21-99) vs. 94(67-100),p <0,001] e pontuações de felicidade mais altas do PODCI [90(65-100) vs. 80(0-100),p=0,016] em comparação com o grupo sem deficiências. A análise de regressão logística demonstrou que a atividade física/semana (odds ratio — OR=1,03; intervalo de confiança — IC95%=1,01-1,05,p=0,002) foi maior nos adolescentes com deficiência. No entanto, atividades domésticas (OR=0,14; IC95%=0,04-0,43,p=0,001) e tempo de tela ≥3 horas/dia (OR=0,09; IC95%=0,02-0,38,p=0,001) foram menores nos adolescentes com deficiência. Conclusões: Os adolescentes com deficiência que frequentam uma organização não governamental (ONG) esportiva não tiveram maior risco de apresentar indicadores adversos à saúde; apesar de apresentarem função física reduzida, relataram mais atividade física, maior felicidade e menos tempo de tela em comparação com adolescentes sem deficiência durante a pandemia da COVID-19.

Particularidades dos Pacientes com Arterite de Takayasu em Idade Mais Avançada: Estudo Coorte, Retrospectivo e Transversal / Characteristics of Older Patients with Takayasu's Arteritis: A Two-Center, Cross-Sectional, Retrospective Cohort Study

Resumo Fundamentos Poucos estudos avaliaram pacientes idosos com Arterite de Takayasu (AT). Objetivo Avaliar o progresso de AT em diferentes grupos etários em seus possíveis efeitos sobre o tratamento medicamentoso e atividade da doença. Métodos este estudo transversal, retrospectivo, do tipo coorte incluiu 66 pacientes com AT. Os pacientes foram entrevistados, e dados dos 12 meses anteriores foram coletados dos prontuários médicos eletrônicos. Os pacientes foram divididos em quatro quartis de acordo com idade atual, e comparados quanto aos dados clínicos e laboratoriais, tratamento, comorbidades, status da doença, e status funcional. Um p<0,05 foi estabelecido como estatisticamente significativo. Resultados Os grupos foram definidos como Q1(22-36 anos, n=16), Q2(37-42 anos, n=18), Q3(43-49 anos, n=17), e Q4(51-66 anos, n=15). A frequência de pacientes com atividade da doença, fadiga, comorbidades e comprometimentos vasculares, e o índice de extensão da doença (DEI. Tak) foram comparáveis entre os grupos. Pacientes com idade mais avançada apresentaram maior duração da doença (p=0,001) e maior comprometimento do status funcional (Q2 versus Q3, p=0,003); menos pacientes usaram prednisona (Q1:43,8%; Q2:33,3%; Q3:11,8%; e Q4:6,7%; p=0,049) e agentes imunossupressores [Q1:100,0%; Q2:66,7%; Q3:58,8% e Q4:46,7%; Q1 versus Q3 (p=0,043) e Q1 versus Q4 (p=0,005) nas análises post-hoc]. Além disso, os níveis de danos da doença, sintomas de uma nova ocorrência de AT, e complicações nos 12 meses precedentes não foram diferentes entre os grupos. Conclusão Pacientes com AT e idade mais avançada requerem mínima intervenção medicamentosa e apresentam maior comprometimento no status funcional, o que pode ser atribuído a fatores relacionados ao envelhecimento.

Abstract Background Few studies have assessed elderly patients with Takayasu's arteritis (TAK). Objectives To evaluate the progression of TAK in different age groups and its possible effects on drug treatment and disease activity. Methods This cross-sectional and retrospective cohort study included 66 TAK patients. Patients were interviewed and data of the 12 preceding months were collected from electronic medical records. The patients were divided into four quartiles according to current age and compared for clinical and laboratory data, treatment, comorbidities, disease status, and functional status. Statistical significance was set at p<0.05. Results The groups were Q1(22-36 years, n=16), Q2(37-42 years, n=18), Q3(43-49 years, n=17), and Q4(51-66 years, n=15). The frequency of patients with disease activity, fatigue, comorbidities and vascular impairments, and the TAK disease extent index were also comparable between the groups. With age, disease duration was longer (p=0.001), fewer patients used prednisone (Q1:43.8%, Q2:33.3%, Q3:11.8%, and Q4:6.7%; p=0.049) and immunosuppressive drugs [Q1:100.0%, Q2:66.7%, Q3:58.8%, and Q4:46.7%; Q1 versus Q3 (p=0.043), and Q1 versus Q4 (p=0.005) in post-hoc analyses], and patients had greater functional status impairment (Q2 versus Q3, p=0.003). In addition, the levels of disease damage, new TAK symptoms, and complications in the preceding 12 months were not different between the groups. Conclusions Older patients with TAK require minimal drug treatment, and have greater impairment of functional status, which may be attributed to aging-related factors.

Emotional, hyperactivity and inattention problems in adolescents with immunocompromising chronic diseases during the COVID-19 pandemic

Abstract Objective: To assess factors associated with emotional changes and Hyperactivity/Inattention (HI) motivated by COVID-19 quarantine in adolescents with immunocompromising diseases. Methods: A cross-sectional study included 343 adolescents with immunocompromising diseases and 108 healthy adolescents. Online questionnaires were answered including socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and validated surveys: Strengths and Difficulties Questionnaire (SDQ), Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0). Results: The frequencies of abnormal emotional SDQ scores from adolescents with chronic diseases were similar to those of healthy subjects (110/343 [32%] vs. 38/108 [35%], p = 0.548), as well as abnormal hyperactivity/inattention SDQ scores (79/343 [23%] vs. 29/108 [27%], p = 0.417). Logistic regression analysis of independent variables associated with abnormal emotional scores from adolescents with chronic diseases showed: female sex (Odds Ratio [OR = 3.76]; 95% Confidence Interval (95% CI) 2.00-7.05; p < 0.001), poor sleep quality (OR = 2.05; 95% CI 1.08-3.88; p = 0.028) and intrafamilial violence during pandemic (OR = 2.17; 95% CI 1.12-4.19; p = 0.021) as independently associated with abnormal emotional scores, whereas total PedsQL score was inversely associated with abnormal emotional scores (OR = 0.95; 95% CI 0.93-0.96; p < 0.0001). Logistic regression analysis associated with abnormal HI scores from patients evidenced that total PedsQL score (OR = 0.97; 95% CI 0.95-0.99; p = 0.010], changes in medical appointments during the pandemic (OR = 0.39; 95% CI 0.19-0.79; p = 0.021), and reliable COVID-19 information (OR = 0.35; 95% CI 0.16-0.77; p = 0.026) remained inversely associated with abnormal HI scores. Conclusion: The present study showed emotional and HI disturbances in adolescents with chronic immunosuppressive diseases during the COVID-19 pandemic. It reinforces the need to promptly implement a longitudinal program to protect the mental health of adolescents with and without chronic illnesses during future pandemics.

Inflamação Coronária Avaliada pela Atenuação de Gordura Pericoronária na Tomografia Computadorizada e Elevação de Citocinas em Usuários Jovens de Esteroides Anabólicos Androgênicos / Coronary Inflammation by Computed Tomography Pericoronary Fat Attenuation and Increased Cytokines in Young Male Anabolic Androgenic Steroid Users

Resumo Fundamento O uso abusivo de esteroides anabólicos androgênicos (EAA) tem sido associado à doença arterial coronariana (DAC). A atenuação de gordura pericoronária (AGp) é um marcador de inflamação coronária, a qual exerce um papel chave no processo aterosclerótico. Objetivo Avaliar AGp e perfil inflamatório em usuários de EAA. Método Vinte indivíduos que realizavam treinamento de força, usuários de EAA (UEAA), 20 não usuários de EAA (NUEAA), e 10 indivíduos sedentários controle (SC) foram avaliados. Inflamação coronária foi avaliada por atenuação de gordura pericoronária média (AGPm) artéria coronária direita (ACD), artéria descendente anterior esquerda (ADA) e artéria circunflexa (ACX). Interleucina (IL)-1 (IL-1), IL-6, IL-10, e TNF-alfa foram avaliados por densidade ótica (DO) em um espectrofotômetro com um filtro de 450 nm. Um p<0,05 indicou significância estatística. Resultados Os UEAA apresentaram maior AGPm na ACD [-65,87 (70,51-60,70) vs. -78,07 (83,66-72,87) vs.-78,46 (85,41-71,99] unidades Hounsfield (HU), respectivamente, p<0,001) e AGPm na ADA [-71,47 (76,40-66,610 vs. -79,32 (84,37-74,59) vs. -82,52 (88,44-75,81) HU, respectivamente, p=0,006) em comparação aos NUEAA e CS. A AGPm na ACX não foi diferente entre os grupos UEAA, NUEAA e CS [-72,41 (77,17-70,37) vs. -80,13 (86,22-72,23) vs. -78,29 (80,63-72,29) HU, respectivamente, p=0,163). Em comparação aos NUEAA e aos CS, o grupo UEAA apresentaram maiores níveis de IL-1 [0,975 (0,847-1,250) vs. 0,437 (0,311-0,565) vs. 0,530 (0,402-0,780) DO, respectivamente, p=0,002), IL-6 [1,195 (0,947-1,405) vs. 0,427 (0,377-0,577) vs. 0,605 (0,332-0,950) DO, p=0,005) e IL-10 [1,145 (0,920-1,292) vs. 0,477 (0,382-0,591) vs. 0,340 (0,316-0,560) DO, p<0,001]. TNF-α não foi diferente entre os grupos UEAA, NUEAA e CS [0,520 (0,250-0,610) vs. 0,377 (0.261-0,548) vs. 0,350 (0,182-430)]. Conclusão Em comparação aos NUEAA e controles, os UEAA apresentam maior AGPm e maior perfil de citocinas inflamatórias sistêmicas, sugerindo que os EAA podem induzir aterosclerose por inflamação coronária e sistêmica.

Abstract Background Anabolic androgenic steroid (AAS) abuse has been associated with coronary artery disease (CAD). Pericoronary fat attenuation (pFA) is a marker of coronary inflammation, which is key in the atherosclerotic process. Objective To evaluate pFA and inflammatory profile in AAS users. Methods Twenty strength-trained AAS users (AASU), 20 AAS nonusers (AASNU), and 10 sedentary controls (SC) were evaluated. Coronary inflammation was evaluated by mean pericoronary fat attenuation (mPFA) in the right coronary artery (RCA), left anterior descending coronary artery (LAD), and left circumflex (LCx). Interleukin (IL)-1 (IL-1), IL-6, IL-10, and TNF-alpha were evaluated by optical density (OD) in a spectrophotometer with a 450 nm filter. P<0.05 indicated statistical significance. Results AASU had higher mPFA in the RCA (-65.87 [70.51-60.70] vs. -78.07 [83.66-72.87] vs.-78.46 [85.41-71.99] Hounsfield Units (HU), respectively, p<0.001) and mPFA in the LAD (-71.47 [76.40-66.61] vs. -79.32 [84.37-74.59] vs. -82.52 [88.44-75.81] HU, respectively, p=0.006) compared with AASNU and SC. mPFA in the LCx was not different between AASU, AASNU, and SC (-72.41 [77.17-70.37] vs. -80.13 [86.22-72.23] vs. -78.29 [80.63-72.29] HU, respectively, p=0.163). AASU compared with AASNU and SC, had higher IL-1, (0.975 [0.847-1.250] vs. 0.437 [0.311-0.565] vs. 0.530 [0.402-0.780] OD, respectively, p=0.002), IL-6 (1.195 [0.947-1.405] vs. 0.427 [0.377-0.577] vs. 0.605 [0.332-0.950] OD, p=0.005) and IL-10 (1.145 [0.920-1.292] vs. 0.477 [0.382-0.591] vs. 0.340 [0.316-0.560] OD, p<0.001). TNF-α was not different between the AASU, AASNU, and SC groups (0.520 [0.250-0.610] vs. 0.377 [0.261-0.548] vs. 0.350 [0.182-430]), respectively. Conclusion Compared with ASSNU and controls, AASU have higher mPFA and higher systemic inflammatory cytokines profile suggesting that AAS may induce coronary atherosclerosis through coronary and systemic inflammation.

Physical and mental health impacts during COVID-19 quarantine in adolescents with preexisting chronic immunocompromised conditions

Abstract Objective: To evaluate physical and mental health indicators in adolescents with preexisting chronic immunocompromised conditions during coronavirus disease 2019 (COVID-19) quarantine. Methods: A cross-sectional study included 355 adolescents with chronic conditions and 111 healthy adolescents. An online self-rated survey was used to investigate socio-demographic features, healthcare routine, and the quarantine impact on physical and mental health. The validated self-reported version of the Strengths and Difficulties Questionnaire (SDQ) was also applied. Results: The median of age [14 (10-18) vs. 15 (10-18) years, p = 0.733] and frequencies of female (61% vs. 60%, p = 0.970) were similar between adolescents with preexisting chronic conditions and healthy adolescents during quarantine of COVID-19 pandemic. The frequencies of abnormal total difficulties score of SDQ were similar in patients and controls (30% vs. 31%, p = 0.775). Logistic regression analysis showed that being female (OR = 1.965; 95% CI = 1.091-3.541, p = 0.024), fear of underlying disease activity/complication (OR = 1.009; 95%CI = 1.001-1.018, p = 0.030) were associated with severe psychosocial dysfunction in adolescents with chronic conditions, whereas school homework (OR = 0.449; 95% CI = 0.206-0.981, p = 0.045) and physical activity (OR = 0.990; 95% CI = 0.981-0.999, p = 0.030) were protective factors. Further analysis of patients with chronic immunocompromised conditions and previous diagnosis of mental disorders (9%) compared with patients without diagnosis showed higher median of total difficulties score (p = 0.001), emotional (p = 0.005), conduct (p = 0.007), peer problems (p = 0.001) and hyperactivity (p = 0.034) in the former group. Conclusion: Adolescents with preexisting chronic immunocompromised conditions during COVID-19 quarantine were not at higher risk of adverse health indicators. Being female, fear of underlying disease activity/complication, and household members working outside of the home were relevant issues for adolescents with preexisting chronic conditions. This study reinforces the need to establish mental health strategies for teens with chronic conditions, particularly during the pandemic.

Abstract Objective: To present an updated and evidence-based guideline for the use of dual-energy x-ray absorptiometry (DXA) to assess body composition in clinical practice. Materials and methods: This Official Position was developed by the Scientific Committee of the Brazilian Association of Bone Assessment and Metabolism ( Associação Brasileira de Avaliação Óssea e Osteometabolismo , ABRASSO) and experts in the field who were invited to contribute to the preparation of this document. The authors searched current databases for relevant publications in the area of body composition assessment. In this second part of the Official Position, the authors discuss the interpretation and reporting of body composition parameters assessed by DXA and the use of DXA for body composition evaluation in special situations, including evaluation of children, persons with HIV, and animals. Conclusion: This document offers recommendations for the use of DXA in body composition evaluation, including indications, interpretation, and applications, to serve as a guiding tool in clinical practice and research for health care professionals in Brazil.

Chronic inflammatory diseases, subclinical atherosclerosis, and cardiovascular diseases: Design, objectives, and baseline characteristics of a prospective case-cohort study ‒ ELSA-Brasil

Abstract Objectives This analysis describes the protocol of a study with a case-cohort to design to prospectively evaluate the incidence of subclinical atherosclerosis and Cardiovascular Disease (CVD) in Chronic Inflammatory Disease (CID) participants compared to non-diseased ones. Methods A high-risk group for CID was defined based on data collected in all visits on self-reported medical diagnosis, use of medicines, and levels of high-sensitivity C-Reactive Protein >10 mg/L. The comparison group is the Aleatory Cohort Sample (ACS): a group with 10% of participants selected at baseline who represent the entire cohort. In both groups, specific biomarkers for DIC, markers of subclinical atherosclerosis, and CVD morbimortality will be tested using weighted Cox. Results The high-risk group (n = 2,949; aged 53.6 ± 9.2; 65.5% women) and the ACS (n=1543; 52.2±8.8; 54.1% women) were identified. Beyond being older and mostly women, participants in the high-risk group present low average income (29.1% vs. 24.8%, p < 0.0001), higher BMI (Kg/m2) (28.1 vs. 26.9, p < 0.0001), higher waist circumference (cm) (93.3 vs. 91, p < 0.0001), higher frequencies of hypertension (40.2% vs. 34.5%, p < 0.0001), diabetes (20.7% vs. 17%, p = 0.003) depression (5.8% vs. 3.9%, p = 0.007) and higher levels of GlycA a new inflammatory marker (p < 0.0001) compared to the ACS. Conclusions The high-risk group selected mostly women, older, lower-income/education, higher BMI, waist circumference, and of hypertension, diabetes, depression, and higher levels of GlycA when compared to the ACS. The strategy chosen to define the high-risk group seems adequate given that multiple sociodemographic and clinical characteristics are compatible with CID.

Innate and Th1/Th17 adaptive immunity in acute and convalescent Brazilian borreliosis disease

ABSTRACT Introduction: Brazilian borreliosis (BB) disease is an infectious disease transmitted by ticks that mimics Lyme disease (LD) from the Northern Hemisphere. The BB clinical picture is characterized by a pathognomonic skin lesion (migratory erythema) and joint, neurological, cardiac and psychiatric symptoms. Innate and Th1/Th17 adaptive immunity seem to play an important role in the pathogenesis of Lyme disease. Objective: The aim of this study was to characterize the role of innate and Th1/Th17 adaptive immunity in BB patients with acute (<3 months) and convalescent (>3 months) disease. Methods: Fifty BB patients (28 with acute and 22 with convalescent disease) without treatment and 30 healthy subjects were evaluated. Levels of 20 cytokines or chemokines associated with innate and Th1/Th17 adaptive immunity were analyzed using Luminex (Millipore Corp., Billerica, MA). Results: Overall, BB patients had increased levels of IL-8 (6.29 vs 2.12 p = 0.002) and MIP-1α/CCL3 (5.20 vs 2.06, p = 0.030), associated with innate immunity, and MIP3B/CCL19 (Th1; 297.86 vs 212.41, p = 0.031) and IL-17A (Th17; 3.11 vs 2.20, p = 0.037), associated with adaptive immunity, compared with the levels of healthy controls. When comparing acute BB vs. convalescent BB subjects vs. healthy controls, IL-1β, IL-8 and MIP-1α/CCL3 (innate mediators) levels were highest in patients in the acute phase of disease (p < 0.05). TNF-α was associated with disseminated symptoms and with humoral reactivity against Borrelia burgdorferi. IL-10 was significantly correlated with IL-6 (r = 0.59, p = 0.003), IL-8 (r = 0.51, p < 0.001), MIP-1α/CCL3 (r = 0.42, p < 0.001) and MIP-3β/CCL19 (r = 0.40, p = 0.002) in all BB patients. Conclusions: This is the first study describing that innate and Th1/Th17 adaptive immunity play a crucial role in BB disease. Furthermore, innate mediators are particularly important in acute BB disease, and TNF-α is associated with evolution of BB symptoms.

Effect of a single high-dose vitamin d3 on the length of hospital stay of severely 25-hydroxyvitamin d-deficient patients with COVID-19

OBJECTIVES: In this ancillary analysis of a multicenter, double-blinded, randomized, placebo-controlled trial, we investigated the effect of a single high dose of vitamin D3 on the length of hospital stay of patients with severe 25-hydroxyvitamin D deficiency and COVID-19. METHODS: The primary outcome was length of hospital stay, defined as the total number of days that patients remained hospitalized from the date of randomization until the date of hospital discharge. Secondary outcomes included serum levels of 25-hydroxyvitamin D, mortality during hospitalization, number of patients admitted to the intensive care unit, and number of patients who required mechanical ventilation. ClinicalTrials.gov: NCT04449718. RESULTS: Thirty-two patients were included in the study. The mean (SD) age was 58.5 (15.6) years, body mass index was 30.8 (8.6) kg/m2, and 25-hydroxyvitamin D level was 7.8 (1.6) ng/mL. No significant difference was observed in the median interquartile range of length of hospital stay between the vitamin D3 group (6.0 [4.0-18.0] days) versus placebo (9.5 [6.3-15.5] days) (log-rank p=0.74; hazard ratio, 1.13 [95% confidence interval (CI), 0.53-2.40]; p=0.76). Vitamin D3 significantly increased serum 25-hydroxyvitamin D levels in the vitamin D3 group compared with that in the placebo group (between-group difference, 23.9 ng/mL [95% CI, 17.7-30.1]; p<0.001). CONCLUSIONS: A dose of 200.000 IU of vitamin D3 did not significantly reduce the length of hospital stay of patients with severe 25-hydroxyvitamin D deficiency and COVID-19.

Persistent symptoms and decreased health-related quality of life after symptomatic pediatric COVID-19: A prospective study in a Latin American tertiary hospital

OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

Poor Sleep quality and health-related quality of life impact in adolescents with and without chronic immunosuppressive conditions during COVID-19 quarantine

OBJECTIVE: To assess the possible factors that influence sleep quality in adolescents with and without chronic immunosuppressive conditions quarantined during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This cross-sectional study included 305 adolescents with chronic immunocompromised conditions and 82 healthy adolescents. Online surveys were completed, which included questions on socio-demographic data and self-rated healthcare routine during COVID-19 quarantine and the following validated questionnaires: the Pittsburgh Sleep Quality Index (PSQI), Pediatric Quality of Life Inventory 4.0 (PedsQL4.0), and Pediatric Outcome Data Collection Instrument (PODCI). RESULTS: The median current age [14 (10-18) vs. 15 (10-18) years, p=0.847] and frequency of female sex (62% vs. 58%, p=0.571) were similar in adolescents with chronic conditions compared with healthy adolescents. The frequency of poor sleep quality was similar in both groups (38% vs. 48%, p=0.118). Logistic regression analysis, including both healthy adolescents and adolescents with chronic conditions (n=387), demonstrated that self-reported increase in screen time (odds ratio [OR] 3.0; 95% confidence interval [CI] 1.3-6.8; p=0.008) and intrafamilial violence report (OR 2.1; 95% CI 1.2-3.5; p=0.008) were independently associated with poor sleep quality in these adolescents. However, the PODCI global function score was associated with a lower OR for poor sleep quality (OR 0.97; 95% CI 0.94-0.99; p=0.001). Further logistic regression, including only adolescents with chronic conditions (n=305), demonstrated that self-reported increase in screen time (OR 3.1; 95% CI 1.4-6.8; p=0.006) and intrafamilial violence report (OR 2.0; 95% CI 1.2-3.4; p=0.011) remained independently associated with poor quality of sleep, whereas a lower PODCI global function score was associated with a lower OR for sleep quality (OR 0.96; 95% CI 0.94-0.98; p<0.001). CONCLUSION: Self-reported increases in screen time and intrafamilial violence report impacted sleep quality in both healthy adolescents and those with chronic conditions. Decreased health-related quality of life was observed in adolescents with poor sleep quality.

Increased modifiable cardiovascular risk factors in patients with Takayasu arteritis: a multicenter cross-sectional study

Abstract Background: Modifiable cardiovascular risk factors (MCRFs), such as those related to aerobic capacity, muscle strength, physical activity, and body composition, have been poorly studied in Takayasu arteritis (TAK). Therefore, the aim of the study was to investigate MCRFs and their relationships with disease status and comorbidities among patients with TAK. Methods: A multicenter cross-sectional study was conducted between 2019 and 2020, in which 20 adult women with TAK were compared with 16 healthy controls matched by gender, age, and body mass index. The following parameters were analyzed: aerobic capacity by cardiopulmonary test; muscle function by timed-stands test, timed up-and-go test, and handgrip test; muscle strength by one-repetition maximum test and handgrip test; body composition by densitometry; physical activity and metabolic equivalent by IPAQ, quality of life by HAQ and SF-36; disease activity by ITAS2010 and NIH score; and presence of comorbidities. Results: Patients with TAK had a mean age of 41.5 (38.0-46.3) years, disease duration of 16.0 (9.5-20.0) years, and a mean BMI of 27.7±4.5 kg/m2. Three out of the 20 patients with TAK had active disease. Regarding comorbidities, 16 patients had systemic arterial hypertension, 11 had dyslipidemia, and two had type 2 diabetes mellitus, while the control group had no comorbidities. TAK had a significant reduction in aerobic capacity (absolute and relative VO2 peak), muscle strength in the lower limbs, increased visceral adipose tissue, waist-to-hip ratio, reduced walking capacity, decreased weekly metabolic equivalent, and quality of life (P< 0.05) as compared to controls. However, there were no correlations between these MCRFs parameters and disease activity. Conclusions: TAK show impairment in MCRFs; therefore, strategies able to improve MCRF should be considered in this disease.(AU)

Increased serum interleukin-6 and tumor necrosis factor alpha levels in fabry disease: correlation with disease burden

OBJECTIVES: Fabry disease (FD) is an X-linked lysosomal disease caused by variants of the GLA gene; the formation of defective alpha-galactosidase A contributes to the accumulation of substrates in several organs. Chronic inflammation is thought to contribute to organ damage in FD patients. METHODS: In total, 36 classic FD patients (15 men/21 women) and 25 healthy controls (20 men/8 women) were assessed. The Mainz Severity Score Index (MSSI) was established after conducting interviews with the patients and chart review. Serum IL-6, IL-1β, and TNF-α levels were evaluated in both groups. RESULTS: The mean age (years) for FD patients was 43.1±15.4 and that for the controls was 47.4±12.2 (p>0.05). Twenty-two patients (59.5%) were treated with enzyme replacement therapy (ERT). Serum IL-6 and TNF-α levels were significantly higher in FD patients than in the controls. Patients treated with ERT had higher serum IL-6 and TNF-α levels than those not treated with ERT. There was no difference in the serum IL-1β levels between patients treated with ERT and those who were not. The MSSI scores in the patients were correlated with serum levels of IL-6 (r=0.60, p<0.001) and TNF-α (r=0.45, p<0.001). CONCLUSION: FD was associated with elevated serum levels of IL-6 and TNF-α in this cohort. The FD patients treated with ERT, particularly, women, exhibited higher levels of serum IL-6 and TNF-α than those not treated with ERT; the serum IL-6 and TNF-α levels were correlated with the MSSI scores reflecting greater disease burden.

Patient-Reported Outcomes in Subjects With A143T and R118C GLA Gene Variants

Abstract Background Fabry disease (FD) is caused by pathogenic variants in the GLA gene. A143T and R118C variants are considered not disease causing. Patient-reported outcomes provide information concerning the effects of their disease but should be carefully analyzed in rare diseases. Objectives To evaluate pain, depression, sleep disturbances, disability and quality of life in A143T or R118C Brazilian subjects and compare to data published for classic FD patients. Methods Nineteen subjects - 8:11 male:female - were evaluated and answered the questionnaires: Brief Pain Inventory (BPI), Hamilton Depression Rating Scale, Pittsburgh Sleep Quality Index, Health Assessment Questionnaire Disability Index (HAQ-DI), Short-Form Health Survey 36 (SF-36). Lyso-Gb3 and residual enzyme activity were obtained. Results Alpha-galactosidase A activity was low in males. Lyso-Gb3 levels were normal in all subjects. Comparing A143T/R118C subjects and FD patients, BPI severity, BPI interference, HAQ-DI values were not different (p>0.05) whereas raw scores for physical functioning (p=0.01) and general health perception (p<0.01) favored A143T/R118C. Depression and sleep disturbances were similar between groups. Conclusions A143T/R188C subjects had normal lyso-Gb3 levels. Depression, sleep disturbances and disability were frequent and under-recognized. However, findings depicted in this study are nonspecific and should not be considered as ground for diagnosing Fabry disease.

Higher rate of rheumatic manifestations and delay in diagnosis in Brazilian Fabry disease patients

Abstract Background: Fabry disease (FD) is an X-linked lysosomal disorder due to mutations in the GLA gene resulting in defective enzyme alpha-galactosidase A. FD patients are frequently misdiagnosed, commonly for rheumatic diseases. Determining pathogenicity of a mutation depends of in silico predictions but mostly on available clinical information and interpretation may change in light of evolving knowledge. Similar signs and symptoms in carriers of GLA gene genetic variants of unknown significance or of benign variants may hamper diagnosis. This study reviews rheumatic and immune-mediated manifestations in a cohort of Brazilian FD patients with classic mutations and also in subjects with GLA gene A143T and R118C mutations. Misdiagnoses, time to correct diagnosis or determination of GLA gene status, time to treatment initiation and reasons for treatment prescription in A143T and R118C subjects are reviewed. Methods: Genotype confirmed classic FD patients (n = 37) and subjects with GLA gene mutations A143T and R118C (n = 19) were referred for assessment. Subjects with R118C and A143T mutations had been previously identified during screening procedures at hemodialysis units. All patients were interviewed and examined by a rheumatologist with previous knowledge of disease and/or mutation status. A structured tool developed by the authors was used to cover all aspects of FD and of common rheumatic conditions. All available laboratory and imaging data were reviewed. Results: Thirty-seven consecutive FD patients were interviewed - 16 male / 21 female (mean age: 43.1 years) and 19 consecutive subjects with GLA gene mutations R118C and A143T were evaluated - 8 male / 11 female (mean age: 39.6 years); 15 [R118C] / 4 [A143T]. Misdiagnosis in FD patients occurred in 11 males (68.8%) and 13 females (61.9%) of which 10 males and 9 females were previously diagnosed with one or more rheumatic conditions, most frequently rheumatic fever or "rheumatism" (unspecified rheumatic disorder). Median time for diagnosis after symptom onset was 16 years (range, 0-52 years). Twenty-two patients were treated with enzyme replacement therapy (ERT) - 13 male and 9 female. Median time to ERT initiation after FD diagnosis was 0.5 years (range, 0-15 years). Rheumatic manifestations occurred in 68.4% of R118C and A143T subjects. Two subjects had been prescribed ERT because of renal disease [R118C] and neuropsychiatric symptoms [A143T]. Conclusion: Misdiagnoses occurred in 64.8% of FD patients, most frequently for rheumatic conditions. Median time for correct diagnosis was 16 years. Rheumatic manifestations are also frequent in subjects with GLA gene R118C and A143T mutations. These results reinforce the need to raise awareness and increase knowledge about Fabry disease among physicians, notably rheumatologists, who definitely have a role in identifying patients and determining disease burden. Decision to start treatment should consider expert opinion and follow local guidelines.(AU)

Comparison of urinary parameters, biomarkers, and outcome of childhood systemic lupus erythematosus early onsetlupus nephritis

Abstract Background: Urinary parameters, anti-dsDNA antibodies and complement tests were explored in patients with childhood-Systemic Lupus Erythematosus (cSLE) early-onset lupus nephritis (ELN) from a large multicenter cohort study. Methods: Clinical and laboratory features of cSLE cases with kidney involvement at presentation, were reviewed. Disease activity parameters including SLEDAI-2 K scores and major organ involvement at onset and follow up, with accrued damage scored by SLICC-DI, during last follow up, were compared with those without kidney involvement. Autoantibodies, renal function and complement tests were determined by standard methods. Subjects were grouped by presence or absence of ELN. Results: Out of the 846 subjects enrolled, mean age 11.6 (SD 3.6) years; 427 (50.5%) had ELN. There was no significant difference in the ELN proportion, according to onset age, but ELN frequency was significantly higher in non-Caucasians (p = 0.03). Hematuria, pyuria, urine casts, 24-h proteinuria and arterial hypertension at baseline, all had significant association with ELN outcome (p < 0.001). With a similar follow up time, there were significantly higher SLICC-DI damage scores during last follow up visit (p = 0.004) and also higher death rates (p < 0.0001) in those with ELN. Low C3 (chi-square test, p = 0.01), but not C3 levels associated significantly with ELN. High anti-dsDNA antibody levels were associated with ELN (p < 0.0001), but anti-Sm, anti-RNP, anti-Ro, anti-La antibodies were not associated. Low C4, C4 levels, low CH50 and CH50 values had no significant association. High erythrocyte sedimentation rate (ESR) was associated with the absence of ELN (p = 0.02). Conclusion: The frequency of ELN was 50%, resulting in higher morbidity and mortality compared to those without ELN. The urinary parameters, positive anti-dsDNA and low C3 are reliable for discriminating ELN.(AU)

Sympatho-Vagal Imbalance is Associated with Sarcopenia in Male Patients with Heart Failure / Desequilíbrio Simpático-Vagal está Associado com Sarcopenia em Pacientes do Sexo Masculino com Insuficiência Cardíaca

Abstract Background: Resting sympathetic hyperactivity and impaired parasympathetic reactivation after exercise have been described in patients with heart failure (HF). However, the association of these autonomic changes in patients with HF and sarcopenia is unknown. Objective: The aim of this study was to evaluate the impact of autonomic modulation on sarcopenia in male patients with HF. Methods: We enrolled 116 male patients with HF and left ventricular ejection fraction < 40%. All patients underwent a maximal cardiopulmonary exercise testing. Maximal heart rate was recorded and delta heart rate recovery (∆HRR) was assessed at 1st and 2nd minutes after exercise. Muscle sympathetic nerve activity (MSNA) was recorded by microneurography. Dual-energy X-ray absorptiometry was used to measure body composition and sarcopenia was defined by the sum of appendicular lean muscle mass (ALM) divided by height in meters squared and handgrip strength. Results: Sarcopenia was identified in 33 patients (28%). Patients with sarcopenia had higher MSNA than those without (47 [41-52] vs. 40 [34-48] bursts/min, p = 0.028). Sarcopenic patients showed lower ∆HRR at 1st (15 [10-21] vs. 22 [16-30] beats/min, p < 0.001) and 2nd min (25 [19-39] vs. 35 [24-48] beats/min, p = 0.017) than non-sarcopenic. There was a positive correlation between ALM and ∆HRR at 1st (r = 0.26, p = 0.008) and 2nd min (r = 0.25, p = 0.012). We observed a negative correlation between ALM and MSNA (r = -0.29, p = 0.003). Conclusion: Sympatho-vagal imbalance seems to be associated with sarcopenia in male patients with HF. These results highlight the importance of a therapeutic approach in patients with muscle wasting and increased peripheral sympathetic outflow.

Resumo Fundamento: Hiperatividade simpática de repouso e uma reativação parassimpática diminuída pós-exercício têm sido descritas em pacientes com insuficiência cardíaca (IC). No entanto, a associação dessas alterações autonômicas em pacientes com IC sarcopênicos ainda não são conhecidas. Objetivo: O objetivo deste estudo foi avaliar o impacto da modulação autonômica sobre sarcopenia em pacientes com IC do sexo masculino. Métodos: Foram estudados 116 pacientes com IC e fração de ejeção ventricular esquerda inferior a 40%. Todos os pacientes foram submetidos ao teste de exercício cardiopulmonar máximo. A frequência cardíaca máxima foi registrada, e o delta de recuperação da frequência cardíaca (∆RFC) foi avaliado no primeiro e no segundo minuto após o exercício. A atividade nervosa simpática muscular (ANSM) foi registrada por microneurografia. A Absorciometria Radiológica de Dupla Energia foi usada para medir composição cpororal, e a sarcopenia definida como a soma da massa muscular apendicular (MMA) dividida pela altura em metros ao quadrado e força da mão. Resultados: A sarcopenia foi identificada em 33 pacientes (28%). Os pacientes com sarcopenia apresentaram maior ANSM que aqueles sem sarcopenia - 47 (41-52) vs. 40 (34-48) impulsos (bursts)/min, p = 0,028). Pacientes sarcopênicos apresentaram ∆RFC mais baixo no primeiro [15 (10-21) vs. 22 (16-30) batimentos/min, p < 0,001) e no segundo [25 (19-39) vs. 35 (24-48) batimentos/min, p = 0,017) minuto que pacientes não sarcopênicos. Observou-se uma correlação positiva entre a MMA e a ANSM (r = -0,29; p = 0,003). Conclusão: Um desequilíbrio simpático-vagal parece estar associado com sarcopenia em pacientes com IC do sexo masculino. Esses resultados destacam a importância de uma abordagem terapêutica em pacientes com perda muscular e fluxo simpático periférico aumentado.

Initial digital vasculitis in a large multicenter cohort of childhood-onset systemic lupus erythematosus / Vasculite digital inicial em uma grande coorte multicêntrica de pacientes com lúpus eritematoso sistêmico de início na infância

Abstract Objectives: To assess clinical digital vasculitis (DV) as an initial manifestation of childhood-onset systemic lupus erythematosus (cSLE) within a large population. Methods: Multicenter cross-sectional study including 852 cSLE patients (ACR criteria) followed in ten Pediatric Rheumatology centers in São Paulo State, Brazil. Results: DV was observed in 25/852 (3%) cSLE patients. Periungual hemorrhage was diagnosed in 12 (48%), periungual infarction in 7 (28%), tip finger ulceration in 4 (16%), painful nodules in 1 (4%) and gangrene in 1 (4%). A poor outcome, with digital resorption, occurred in 5 (20%). Comparison of patients with and without DV revealed higher frequency of malar rash (80% vs. 53%, p = 0.008), discoid rash (16% vs. 4%, p = 0.017), photosensitivity (76% vs. 45%, p = 0.002) and other cutaneous vasculitides (80% vs. 19%, p < 0.0001), whereas the frequency of overall constitutional features (32% vs. 61%, p = 0.003), fever (32% vs. 56%, p = 0.020) and hepatomegaly (4% vs. 23%, p = 0.026) were lower in these patients. Frequency of female gender, severe multi-organ involvement, autoantibodies profile and low complement were alike in both groups (p > 0.05). SLEDAI-2K median, DV descriptor excluded, was significantly lower in patients with DV compared to those without this manifestation [10 (0-28) vs. 14 (0-58), p = 0.004]. Visceral vasculitis or death were not observed in this cSLE cohort. The frequency of cyclophosphamide use (0% vs. 18%, p = 0.014) was significantly lower in the DV group. Conclusion: Our large multicenter study identified clinical DV as one of the rare initial manifestation of active cSLE associated with a mild multisystemic disease, in spite of digital resorption in some of these patients.

Resumo Objetivos: Avaliar a vasculite digital (VD) clínica como uma manifestação inicial do lúpus eritematoso sistêmico de início na infância (LESi) em uma grande população. Métodos: Estudo transversal multicêntrico que incluiu 852 pacientes com LESi (critérios do ACR), acompanhados em dez centros de reumatologia pediátrica do Estado de São Paulo. Resultados: Observou-se VD em 25/852 (3%) pacientes com LESi. Diagnosticaram-se hemorragia periungueal em 12 (48%), infarto periungueal em sete (28%), úlcera de ponta de dígito em quatro (16%), nódulos dolorosos em um (4%) e gangrena em um (4%). Um desfecho ruim, com reabsorção digital, ocorreu em cinco (20%) pacientes. A comparação entre pacientes com e sem VD revelou maior frequência de erupção malar (80% vs. 53%, p = 0,008), erupção discoide (16% vs. 4%, p = 0,017), fotossensibilidade (76% vs. 45% p = 0,002) e outras vasculites cutâneas (80% vs. 19%, p < 0,0001), enquanto a frequência de características constitucionais totais (32% vs. 61%, p = 0,003), febre (32% vs. 56% p = 0,020) e hepatomegalia (4% vs. 23%, p = 0,026) foram menores nesses pacientes. A frequência do gênero feminino, o envolvimento grave de múltiplos órgãos, perfil de autoanticorpos e baixo complemento foram semelhantes nos dois grupos (p > 0,05). A mediana no Sledai-2 K, exclusive o descritor de VD, foi significativamente menor nos pacientes com VD em comparação com aqueles sem essa manifestação [10 (0 a 28) vs. 14 (0 a 58), p = 0,004]. Não foram observadas vasculite visceral nem morte nessa coorte de pacientes com LESi. A frequência de uso de ciclofosfamida (0% vs. 18%, p = 0,014) foi significativamente menor no grupo VD. Conclusão: Este grande estudo multicêntrico identificou a VD clínica como uma rara manifestação inicial do LESi ativo, associada a doença multissistêmica leve, apesar da ocorrência de reabsorção digital em alguns desses pacientes.

Relapsing polychondritis: prevalence of cardiovascular diseases and its risk factors, and general disease features according to gender / Policondrite recidivante: prevalência de doenças cardiovasculares e seus fatores de risco e características gerais da doença de acordo com o gênero

ABSTRACT The comorbidities in relapsing polychondritis have been scarcely described in the literature. Moreover, apart from a few relapsing polychondritis epidemiological studies, no studies specifically addressing relapsing polychondritis distribution according to gender are available. Therefore, the objectives of the present study were: (a) to analyze the prevalence of cardiovascular diseases and its risk factors in a series of patients with relapsing polychondritis; (b) to determine the influence of gender on relapsing polychondritis. A cross-sectional tertiary single center study evaluating 30 relapsing polychondritis cases from 1990 to 2016 was carried out. To compare comorbidities, 60 healthy individuals matched for age-, gender-, ethnicity- and body mass index were recruited. The mean age of relapsing polychondritis patients was 49.0 ± 12.4 years, the median disease duration 6.0 years, and 70% were women. A higher frequency of arterial hypertension (53.3% vs. 23.3%; p = 0.008) and diabetes mellitus (16.7% vs. 3.3%; p = 0.039) was found in the relapsing polychondritis group, compared to the control group. As an additional analysis, patients were compared according to gender distribution (9 men vs. 21 women). The clinical disease onset features were comparable in both genders. However, over the follow-up period, male patients had a greater prevalence of hearing loss, vestibular disorder and uveitis events, and also received more cyclophosphamide therapy (p < 0.05). There was a high prevalence of arterial hypertension and diabetes mellitus, and the male patients seemed to have worse prognosis than the female patients in the follow up.

RESUMO Há escassez de estudos na literatura sobre as comorbidades na policondrite recidivante (PR). Além disso, exceto por alguns estudos epidemiológicos sobre a PR, não existem trabalhos que analisem especificamente a distribuição da PR de acordo com o gênero. Portanto, os objetivos do presente estudo foram: (a) analisar a prevalência de doenças cardiovasculares e seus fatores de risco em uma série de pacientes com PR; (B) determinar a influência do gênero na PR. Fez-se um estudo transversal unicêntrico que avaliou 30 casos de PR entre 1990 e 2016. Para comparar as comorbidades, foram recrutados 60 indivíduos saudáveis pareados por idade, gênero, etnia e índice de massa corporal. A idade média dos pacientes com PR foi de 49,0 ± 12,4 anos. A duração média da doença foi de 6,0 anos e 70% eram mulheres. Foi observada uma maior frequência de hipertensão arterial (53,3% vs. 23,3%, p = 0,008) e diabetes mellitus (16,7% vs. 3,3%; p = 0,039) no grupo PR em comparação com o grupo controle. Em uma análise adicional, os pacientes foram comparados de acordo com a distribuição de gênero (nove homens versus 21 mulheres). As características clínicas iniciais da doença foram comparáveis em ambos os sexos. No entanto, durante o período de seguimento, os pacientes do sexo masculino tiveram maior prevalência de perda auditiva, envolvimento vestibular e eventos de uveíte e também receberam mais tratamento com ciclofosfamida (p < 0,05). Houve uma alta prevalência de hipertensão arterial e diabetes mellitus e os pacientes do sexo masculino apresentaram pior prognóstico do que as pacientes do sexo feminino no seguimento.
