None of the patients (median age: 9, range: 7-18 years; 3 females; 2 males) had preexisting pediatric chronic conditions. At the follow-up visit, two patients exhibited severe perfusion defect developed in the left ventricular cavity, suggesting extensive myocardial ischemia (MBF <2.0) and one patient showed persistent mild pericardial effusion. Others two patients demonstrated endothelial dysfunction. Nevertheless, all patients had lower predicted values in the VO2peak, VO2VAT, OUES, and O-2 Pulse (range: 35.2%-64.5%; 15.6%-38.2%; 1.0-1.3 L/min; 4-7 ml/beat), respectively. Our d suggested that previously health MIS-C patients had impaired MBF, endothelial dysfunction and lower cardiopulmonary capacity at follow-up analysis. Multidisciplinary further investigations should be conducted to reinforce these findings.
- Segmental cardiac strain assessment by two-dimensional speckle-tracking echocardiography in surviving MIS-c patients: Correlations with myocardial flow reserve (MFR) by 13 N-ammonia PET-CT(2022) LEAL, Gabriela Nunes; ASTLEY, Camila; LIMA, Marcos Santos; DINIZ, Maria de Fatima Rodrigues; LIANZA, Alessandro Cavalcanti; SAWAMURA, Karen Saori Shiraishi; MENEZES, Carolina Rocha Brito; SILVA, Camila Lino Martins Rodrigues da; BAIN, Vera; IMADA, Rodrigo; CHALELA, William; PEREIRA, Maria Fernanda Badue; MARQUES, Heloisa Helena de Sousa; BUCHPIGUEL, Carlos Alberto; GUALANO, Bruno; SILVA, Clovis ArturBackground Multisystem inflammatory syndrome in children (MIS-c) is associated with severe cardiovascular impairment and eventually death. Pathophysiological mechanisms involved in myocardial injury were scarcely investigated, and cardiovascular outcomes are uncertain. Autopsy studies suggested that microvascular dysfunction may be relevant to LV impairment. Objective We aimed to evaluate segmental LV longitudinal strain by 2DST echocardiography and myocardial flow reserve (MFR) by 13 N-ammonia PET-CT, in six surviving MIS-c patients. Methods Each patient generated 34 LV segments for combined 2DST and MRF analysis. MFR was considered abnormal when <2, borderline when between 2 and 2.5 and normal when >2.5. Results From July 2020 to February 2021, six patients were admitted with MIS-c: three males, aged 9.3 (6.6-15.7) years. Time from admission to the follow-up visit was 6.05 (2-10.3) months. Although all patients were asymptomatic and LV EF was >= 55%, 43/102 (42.1%) LV segments showed MFR r = .36, p = .03 for basal segments; r = .41, p = .022 for mid segments; r = .42, p = .021 for apical segments. Median peak systolic longitudinal strain was different among MRF categories: 18% (12%-24%) for abnormal, 18.5% (11%-35%) for borderline, and 21% (12%-32%) for normal MFR (p = .006). Conclusion We provided preliminary evidence that surviving MIS-c patients may present subclinical impairment of myocardial microcirculation. Segmental cardiac strain assessment 2DST seems useful for MIS-c cardiovascular follow-up, given its good correlation with 13 N-ammonia PET-CT derived MFR.

- Seroconversion in asymptomatic COVID-19 pediatric patients with rheumatic diseases of one tertiary referral hospital(2022) SIMON, Juliana R.; PEREIRA, Maria F. B.; MARQUES, Heloisa H.; ELIAS, Adriana M.; SAKITA, Neusa K.; FERREIRA, Juliana C. O. A.; PRECIOSO, Alexander Roberto; GRISI, Sandra J. F. E.; FERRER, Ana Paula S.; BAIN, Vera; SILVA, Clovis A.; CAMPOS, Lucia M. A.Objectives: To evaluate seroconverted asymptomatic COVID-19 in pediatric Autoimmune Rheumatic Diseases (ARDs) patients and to identify the risk factors related to contagion.Methods: A cross-sectional study was conducted in March 2021, before vaccination of children and adolescents in Brazil, including 77 pediatric ARDs patients, followed at a tertiary hospital and 45 healthy controls, all of them without a previous diagnosis of COVID-19. Data was obtained by a questionnaire with demographic data, symp-toms compatible with COVID-19 over the previous year, and contact with people with confirmed COVID-19. Patient's medical records were reviewed to access data regarding disease and current medications. A qualitative immunochromatographic SARS-CoV-2 test was performed on all participants.Results: Patients and controls were similar in terms of female gender (70.1% vs. 57.8%, p = 0.173), age (14 vs. 13 years, p = 0.269) and SARS-CoV-2 positive serology (22% vs. 15.5%, p = 0.481). 80.5% of rheumatic patients were in use of immunosuppressive drugs: 27.3% of them used corticosteroids (33.3% in high doses), and 7.8% on immunobiologicals. No statistical differences were found between positive (n = 17) and negative serol-ogy (n = 60) patients regarding demographic/socioeconomic data, contact with people with confirmed COVID-19, use and number of immunosuppressive drugs, use and dose of corticosteroids, use of hydroxychloroquine and immunobiological drugs (p > 0.05).Conclusions: Pediatric rheumatic disease patients were infected at the same rate as healthy ones. Neither the underlying pathology nor its immunosuppressive treatment seemed to interfere with contagion risk.
- SARS-CoV-2 and rhinovirus infections: are there differences in clinical presentation, laboratory abnormalities, and outcomes in the pediatric population?(2022) PEREIRA, Maria Fernanda Badue; SUGUITA, Priscila; LITVINOV, Nadia; FARHAT, Sylvia Costa Lima; PAULA, Camila Sanson Yoshino de; LAZARI, Carolina dos Santos; BEDE, Pedro Vale; FRAMIL, Juliana Valeria de Souza; BUENO, Catarina; BRANAS, Priscila Cristina Abduch Adas; GUIMARAES, Irina Monteiro da Costa; LEITE, Marcia Marques; NAVEGA, Ana Carolina Barsaglini; NANBU, Danilo Yamamoto; SCHVARTSMAN, Claudio; PINHO, Joao Renato Rebello; SILVA, Clovis Artur Almeida; MARQUES, Heloisa Helena de SousaThis study aims to assess COVID-19 and other respiratory viruses in pediatric patients. Between April 17 and September 30, 2020, we collected 1,566 respiratory samples from 1,044 symptomatic patients who were younger than 18 years old to assess SARS-CoV-2 infection. Of these, 919 were analyzed for other respiratory pathogens (ORP). Patients with laboratory-confirmed COVID-19 or ORP were included. We evaluated 76 pediatric COVID-19 infections and 157 other respiratory virus infections. Rhinovirus occurred in 132/157 (84%). COVID-19 patients who were significantly older, had more fevers, headaches and pneumonia than those with ORP. The median white blood cell count was lower in patients with SARS-CoV-2 than in those with ORP (6,470 versus 8,170; p=0.02). COVID-19 patients had significantly worse symptoms than those with ORP.
- Technical performance of a lateral flow immunoassay for detection of anti-SARS-CoV-2 IgG in the outpatient follow-up of non-severe cases and at different times after vaccination: comparison with enzyme and chemiluminescent immunoassays(2022) BARREIRA, Gabriel Acca; SANTOS, Emilly Henrique Dos; PEREIRA, Maria Fernanda Badue; RODRIGUES, Karen Alessandra; ROCHA, Mussya Cisotto; KANUNFRE, Kelly Aparecida; MARQUES, Heloisa Helena de Sousa; OKAY, Thelma SuelyThis study assessed the technical performance of a rapid lateral flow immunochromatographic assay (LFIA) for the detection of anti-SARS-CoV-2 IgG and compared LFIA results with chemiluminescent immunoassay (CLIA) results and an inhouse enzyme immunoassay (EIA). To this end, a total of 216 whole blood or serum samples from three groups were analyzed: the first group was composed of 68 true negative cases corresponding to blood bank donors, healthy young volunteers, and eight pediatric patients diagnosed with other coronavirus infections. The serum samples from these participants were obtained and stored in a pre-COVID-19 period, thus they were not expected to have COVID-19. In the second group of true positive cases, we chose to replace natural cases of COVID-19 by 96 participants who were expected to have produced anti-SARS-CoV-2 IgG antibodies 30-60 days after the vaccine booster dose. The serum samples were collected on the same day that LFIA were tested either by EIA or CLIA. The third study group was composed of 52 participants (12 adults and 40 children) who did or did not have antiSARS-CoV-2 IgG antibodies due to specific clinical scenarios. The 12 adults had been vaccinated more than seven months before LFIA testing, and the 40 children had nonsevere COVID-19 diagnosed using RT-PCR during the acute phase of infection. They were referred for outpatient follow-up and during this period the serum samples were collected and tested by CLIA and LFIA. All tests were performed by the same healthcare operator and there was no variation of LFIA results when tests were performed on finger prick whole blood or serum samples, so that results were grouped for analysis. LFIA???s sensitivity in detecting anti-SARS-CoV-2 IgG antibodies was 90%, specificity 97.6%, efficiency 93%, PPV 98.3%, NPV 86.6%, and likelihood ratio for a positive or a negative result were 37.5 and 0.01 respectively. There was a good agreement (Kappa index of 0.677) between LFIA results and serological (EIA or CLIA) results. In conclusion, LFIA analyzed in this study showed a good technical performance and agreement with reference serological assays (EIA or CLIA), therefore it can be recommended for use in the outpatient follow-up of non-severe cases of COVID-19 and to assess anti-SARS-CoV-2 IgG antibody production induced by vaccination and the antibodies decrease over time. However, LFIAs should be confirmed by using reference serological assays whenever possible.
