- Echocardiographic Follow-up of Perinatally HIV-infected Children and Adolescents Results From a Single-center Retrospective Cohort Study in Brazil(2020) VALLILO, Nathalia Gaspar; DURIGON, Giuliana Stravinskas; LIANZA, Alessandro Cavalcanti; DINIZ, Maria de Fatima Rodrigues; SAWAMURA, Karen Saori Shiraishi; BRITO, Carolina Rocha; MARQUES, Heloisa Helena de Souza; FERRARO, Alexandre Archanjo; LEAL, Gabriela NunesBackground: The effects of HIV and antiretroviral therapy on cardiovascular system of perinatally infected children throughout their development are not fully understood. Objectives: To determine the prevalence of cardiac abnormalities in a retrospective cohort of perinatally HIV-infected patients and to investigate associations between echocardiographic and clinical data during their follow-up. Methods: Review of medical records and echocardiogram reports of 148 perinatally HIV-infected patients between January 1991 and December 2015. Results: Four hundred and eighty echocardiograms were analyzed and 46 (31%) patients showed cardiac abnormalities, frequently subclinical and transient. Nadir CD4 count was higher in patients with consistently normal echocardiogram: 263 (4-1480) versus 202 (5-1746) cells/mu L, P = 0.021. Right ventricular (RV) dilation was detected in 18.9%, left ventricular (LV) dilation in 21.6%, septal hypertrophy in 12.2%, LV posterior wall hypertrophy in 6%, LV systolic dysfunction in 8% and pulmonary hypertension in 8.7% of patients. Opportunistic infections were associated with RV dilation [odds ratio (OR = 4.34; 1.78-10.53; P < 0.01)], pulmonary hypertension (OR = 8.78; 2.80-27.51; P < 0.01) and LV systolic dysfunction (OR = 5.38; 1.55-18.71; P < 0.01). Longer duration of highly active antiretroviral therapy was associated with reduced risk of LV dilation (OR = 0.91; 0.85-0.97; P < 0.01) and systolic dysfunction (OR = 0.71; 0.59-0.85; P < 0.01). Protease inhibitors use was associated with reduced risk of RV dilation (OR = 0.54; 0.30-0.97; P < 0.05), LV dilation (OR = 0.35; 0.21-0.60; P < 0.01) and LV systolic dysfunction (OR = 0.07; 0.02-0.31; P < 0.01). Higher CD4 count was associated with lower risk of LV systolic dysfunction (OR = 0.82; 0.69-0.98; P < 0.05). Conclusions: Echocardiograms identified cardiac abnormalities among children with perinatally acquired HIV infection, and data suggest that immunologic status and therapeutic strategies throughout development can influence cardiac disease burden in this population.
- Hepatitis C in Children and Adolescents of a Brazilian Tertiary Center Identifying Patients Eligible for Direct-Acting Antivirals(2020) HIRSCH, Camila Bellettini; PEREIRA, Maria Fernanda Badue; BENEVIDES, Gabriel Nuncio; BERNARDES, Tamires Miranda; PALANDRI, Giovanna Gavros; BASTOS, Karina Lucio de Medeiros; TOMA, Ricardo Katsuya; AZEVEDO, Ramiro Anthero de; MARQUES, Heloisa Helena de SousaWe evaluated 113 pediatric patients with chronic hepatitis C from 2009 to 2019 at a Brazilian tertiary center. Seventy patients received pegylated-interferon treatment. The sustained virologic response was 61.4%, and 92.8% reported side effects. Currently, we are following 39 patients with chronic hepatitis C, 24 of whom are eligible for treatment with direct-acting antivirals according to Brazilian recommendations.

- High Fatality Rates in Pediatric Multisystem Inflammatory Syndrome: A Multicenter Experience From the Epicenter of Brazil's Coronavirus Pandemic(2024) ALMEIDA, Flavia Jacqueline; JAROVSKY, Daniel; FARIAS, Camila Giuliana Almeida; CASTILHO, Taisa Roberta Ramos Nantes de; CAETANO, Thiago Gara; BORSETTO, Cibele Cristina Manzoni Ribeiro; AGUIAR, Andressa Simoes; ARAUJO, Carolina Serafini de; PEREIRA, Maria Fernanda Badue; MARQUES, Heloisa Helena de Sousa; SILVA, Clovis Artur; TANNURE, Andressa Ribeiro de Matos; PRADO, Rogerio; MAU, Luciana Becker; ALVARES, Paula Andrade; SIQUEIRA, Antonio Carlos de; SCREMIN, Gustavo Paro; OTSUKA, Marcelo; ARNONI, Mariana Volpe; LAPORTE, Roberta Machado Rissoni; CARLESSE, Fabianne Altruda de Moraes Costa; EJZENBERG, Fernanda; BEREZIN, Eitan Naaman; SAFADI, Marco Aurelio PalazziBackground:Brazil ' s case fatality rate (CFR) of pediatric multisystem inflammatory syndrome in children and adolescents (MIS-C) is among the highest worldwide. Despite these concerns, limited hospital-based and comprehensive pediatric data have been published on MIS-C in Brazilian children.We performed a descriptive analysis of the MIS-C scores in 16 public and private hospitals providing secondary and tertiary care in the metropolitan area of Sao Paulo, Brazil. Clinical and demographic information were systematically extracted from the electronic medical records of each patient. Logistic regression analysis was performed to identify the combined effects of MIS-C phenotype, disease severity and comorbidity as dependent variables.A total of 101 patients met the MIS-C criteria and were evaluated. The median age was 67 months, 60% were male, 28.7% were black or afrodescendant and 62.3% were admitted to public hospitals. Underlying medical conditions were observed in 16.8% of patients and were associated with a longer duration of hospitalization. A Kawasaki disease-like phenotype was observed in 43.5% of patients, and they demonstrated a trend of lower median age. Children with severe MIS-C were older (median age 91 months vs. 36 months) and had a nonspecific phenotype, more cardiovascular and respiratory involvement and kidney injury; 73.3% required intensive care, 20.8% required mechanical ventilation and 35.6% required inotropic support. Four deaths occurred (CFR = 3.9%), three of which were in healthy participants.We identified a lower median age, particularly among children with Kawasaki disease-like phenotypes, those with a significant need for intensive care, and a high CFR in MIS-C. Our findings confirmed the increased severity of the disease in the selected Brazilian population.Background:Brazil ' s case fatality rate (CFR) of pediatric multisystem inflammatory syndrome in children and adolescents (MIS-C) is among the highest worldwide.

- Breakthrough Candidemia in Pediatric Patients With Cancer From a Brazilian Center(2021) BARRIENTOS, Anna Carlota Mott; ALMEIDA JUNIOR, Joao Nobrega de; LITVINOV, Nadia; BAIN, Vera; CRISTOFANI, Lilian Maria; PEREIRA, Maria Fernanda Badue; PAULA, Camila Sanson Yoshino de; MOTTA, Adriana Lopes; ROSSI, Flavia; NEGRO, Gilda Maria Barbaro Del; THOMAZ, Danilo Yamamoto; MARQUES, Heloisa Helena SousaWe analyzed 19 cases of breakthrough candidemia from a referral pediatric cancer center in Brazil. All patients had neutropenia and were under antifungal prophylactic regimens, mostly micafungin (68%). Most of the patients were treated with amphotericin B formulations and 30-day mortality was 21%. Candida parapsilosis was the main etiologic agent (63%), and horizontal transmission was not evidenced by microsatellite analysis.
