- Maternal vaccination as an additional approach to improve the protection of the nursling: Anti-infective properties of breast milk(2022) ZHENG, Yingying; CORREA-SILVA, Simone; PALMEIRA, Patricia; CARNEIRO-SAMPAIO, MagdaHuman milk constitutes a secretion with unique functions of both nourishing the nursling and providing protection against enteric and respiratory infections, mainly due to its content of secretory IgA antibodies but also due to the presence of a plethora of bioactive factors. Specific IgA antibodies are produced locally by plasma cells derived from B lymphocytes that migrate from other mucosae to the mammary gland during lactation, particularly from the gastrointestinal and respiratory tracts. Therefore, here, the authors will provide a comprehensive review of the content and functions of different nutritional and bioactive anti-infectious components from breast milk, such as oligosaccharides, lactoferrin, haptocorrin, ??-lactalbumin, k-casein, lysozyme, lactoperoxidase, mucin, fatty acids, defensins, cytokines and chemokines, hormones and growth factors, complement proteins, leukocytes and nucleic acids, including microRNAs, among many others, and the induction of antibody responses in breast milk after maternal vaccination with several licensed vaccines, including the anti-SARS-CoV-2 vaccine preparations used worldwide. Currently, in the midst of the pandemic, maternal vaccination has re-emerged as a crucial source of passive immunity to the neonate through the placenta and breastfeeding, considering that maternal vaccination can induce specific antibodies if performed during pregnancy and after delivery. There have been some reports in the literature about milk IgA antibodies induced by bacterial antigens or inactivated virus vaccines, such as anti-diphtheria-tetanus-pertussis, anti-influenza viruses, anti-pneumococcal and meningococcal polysaccharide preparations. Regarding anti-SARS-CoV-2 vaccines, most studies demonstrate elevated levels of specific IgA and IgG antibodies in milk with virus-neutralizing ability after maternal vaccination, which represents an additional approach to improve the protection of the nursling during the entire breastfeeding period.
- Circulating sTREM-1 as a predictive biomarker of pediatric multisystemic inflammatory syndrome (MIS-C)(2023) GONCALVES, Guilherme S.; CORREA-SILVA, Simone; ZHENG, Yingying; AVELAR, Isabela; MONTENEGRO, Marilia M.; FERREIRA, Arthur E. F.; BAIN, Vera; FINK, Thais T.; SUGUITA, Priscila; ASTLEY, Camilla; LINDOSO, Livia; MARTINS, Fernanda; MATSUO, Olivia M.; FERREIRA, Juliana C. O. A.; FIRIGATO, Isabela; GONCALVES, Fernanda de Toledo; PEREIRA, Maria Fernanda B.; SILVA, Clovis Artur A. da; CARNEIRO-SAMPAIO, Magda; MARQUES, Heloisa H. S.; PALMEIRA, PatriciaThe exacerbation of the inflammatory response caused by SARS-CoV-2 in adults promotes the production of soluble mediators that could act as diagnostic and prognostic biomarkers for COVID-19. Among the potential biomarkers, the soluble triggering receptor expressed on myeloid cell-1 (sTREM-1) has been described as a predictor of inflammation severity. The aim was to evaluate sTREM-1 and cytokine serum concentrations in pediatric patients during the acute and convalescent phases of COVID-19. This was a prospective study that included 53 children/adolescents with acute COVID-19 (Acute-CoV group); 54 who recovered from COVID-19 (Post-CoV group) and 54 controls (Control group). Preexisting chronic conditions were present in the three groups, which were defined as follows: immunological diseases, neurological disorders, and renal and hepatic failures. The three groups were matched by age, sex, and similar preexisting chronic conditions. No differences in sTREM-1 levels were detected among the groups or when the groups were separately analyzed by preexisting chronic conditions. However, sTREM-1 analysis in the seven multisystemic inflammatory syndrome children (MIS-C) within the Acute-Cov group showed that sTREM-1 concentrations were higher in MIS-C vs non-MIS-C acute patients. Then, the receiver operating curve analysis (ROC) performed with MIS-C acute patients revealed a significant AUC of 0.870, and the sTREM-1 cutoff value of > 5781 pg/mL yielded a sensitivity of 71.4 % and a specificity of 91.3 % for disease severity, and patients with sTREM-1 levels above this cutoff presented an elevated risk for MIS-C development in 22.85-fold (OR = 22.85 [95 % CI 1.64-317.5], p = 0.02). The cytokine analyses in the acute phase revealed that IL-6, IL-8, and IL-10 concentrations were elevated regardless of whether the patient developed MIS-C, and those levels decreased in the convalescent phase, even when compared with controls. Spearman correlation analysis generated positive indexes between sTREM-1 and IL-12 and TNF-alpha concentrations, only within the Acute-CoV group. Our findings revealed that sTREM-1 in pediatric patients has good predictive accuracy as an early screening tool for surveillance of MIS-C cases, even in patients with chronic underlying conditions.
- Health-related quality of life and functionality in primary caregiver of surviving pediatric COVID-19(2023) MARTINS, Fernanda; GONCALVES, Fernanda T.; IMAMURA, Marta; BARBOZA, Daniela S.; MATHEUS, Denise; PEREIRA, Maria Fernanda B.; MARQUES, Heloisa H. S.; CORREA-SILVA, Simone; MONTENEGRO, Marilia M.; FINK, Thais T.; LINDOSO, Livia; BAIN, Vera; FERREIRA, Juliana C. O. A.; ASTLEY, Camilla; MATSUO, Olivia M.; SUGUITA, Priscila; TRINDADE, Vitor; PAULA, Camila S. Y.; LITVINOV, Nadia; PALMEIRA, Patricia; GUALANO, Bruno; DELGADO, Artur F.; CARNEIRO-SAMPAIO, Magda; FORSAIT, Silvana; ODONE-FILHO, Vicente; ANTONANGELO, Leila; BATTISTELLA, Linamara R.; SILVA, Clovis A.ObjectivesTo prospectively assess health-related quality of life (HRQoL), global functionality, and disability in primary caregivers of surviving children and adolescents after COVID-19. MethodsA longitudinal observational study was carried out on primary caregivers of surviving pediatric post-COVID-19 patients (n = 51) and subjects without COVID-19 (n = 60). EuroQol five-dimension five-level questionnaire (EQ-5D-5L) and 12-question WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) were answered for both groups. The univariate regression analysis was carried out using SPSS (v 20) and significance was established at 5%. ResultsThe median duration between COVID-19 diagnosis in children and adolescents and longitudinal follow-up visits was 4.4 months (0.8-10.7). The median age of children and adolescents caregivers with laboratory-confirmed COVID-19 was similar to primary caregivers of subjects without laboratory-confirmed COVID-19 [43.2 (31.6-60.9) vs. 41.5 (21.6-54.8) years, p = 0.08], as well as similar female sex (p = 1.00), level of schooling (p = 0.11), social assistance program (p = 0.28), family income/month U$ (p = 0.25) and the number of household's members in the residence (p = 0.68). The frequency of slight to extreme problems (level & GE; 2) of the pain/discomfort domain according to EQ-5D-5L score was significantly higher in the former group [74% vs. 52.5%, p = 0.03, OR = 2.57 (1.14-5.96)]. The frequency of disability according to WHODAS 2.0 total score was similar to those without disability and unknown (p = 0.79); however, with a very high disability in both groups (72.5% and 78.3%). Further analysis of primary caregivers of children and adolescents with post-COVID-19 condition (PCC) [n = 12/51 (23%)] compared to those without PCC [n = 39/51(77%)] revealed no differences between demographic data, EQ-5D-5L and WHODAS 2.0 scores in both groups (p > 0.05). ConclusionWe longitudinally demonstrated that pain/discomfort were predominantly reported in approximately 75% of primary caregiver of COVID-19 patients, with high disability in approximately three-quarters of both caregiver groups. These data emphasized the prospective and systematic caregiver burden evaluation relevance of pediatric COVID-19.

B.; BORBELY, A. U.; CARDOSO, E. C.; CORREA-SILVA, S.; BONETTI, T. C.; SERAFINI, P. C.; MOTTA, E. L.; FREITAS, V. M.; MYUNG, L. H. J.; ABRAAO, M. S.; BEVILAQUA, E.- Macrophage profile and homing into breast milk in response to ongoing respiratory infections in the nursing infant(2020) ZHENG, Yingying; CORREA-SILVA, Simone; SOUZA, Eloisa Correa de; RODRIGUES, Regina Maria; FONSECA, Fernanda A. Macaferri da; GILIO, Alfredo Elias; CARNEIRO-SAMPAIO, Magda; PALMEIRA, PatriciaStudies have shown that immune components of human milk can be changed during an infection in the nursing infant. Macrophages are abundant in human milk and they are classified into inflammatory (CD16(-)) and noninflammatory (CD16(+)) subsets. This study investigated CD16(+) and CD16(-) macrophage homing into breast milk in response to ongoing infections in nursing infants. Peripheral blood and mature milk were collected from 33 healthy mothers of nursing infants with respiratory infections (Group I) and from 26 healthy mothers of healthy nursing infants (Group H). Blood and milk total, CD16(-) and CD16(+) monocyte (Mo)/macrophage (M phi) subsets, respectively, and CCR2 and CX3CR1 expression and cytokine levels were analyzed by flow cytometry. CCL2 and CX3CL1 were quantified by ELISA and cytokines by flow cytometry in serum and milk. There was an increase of total and CD16(+) M phi, and, also a decrease of CD16- M phi frequencies in maternal milk from Group I compared to Group H, but absolute numbers analyses showed higher numbers of all subpopulations of milk M phi in Group I compared to Group H. Higher numbers of CX3CR1(+)CD16(+) and double-staining of CCR2 and CX3CR1 in both CD16(+) and CD16(-) cells were observed in milk during infant infection, which weren't observed in the blood. CCR2 expression was hardly found in milk CD16(-) M phi in both groups. CCL2 and CX3CL1 were both higher in milk than in blood from both groups, but Group I showed higher levels of these chemokines in milk than Group H. Breast milk showed higher IL-6 and IL-8 concentrations than serum, and infant infection caused an increase in these cytokines only in milk. Our findings suggest that milk M phi profiles are different from blood Mo, and the ongoing infection in the nursing infant could change milk M phi to a more anti-inflammatory profile compared to that in the healthy group, possibly as an additional strategy of infant protection.
- Salivary, serological, and cellular immune response to the CoronaVac vaccine in health care workers with or without previous COVID-19(2022) ORTEGA, Marina Mazzilli; SILVA, Lais Teodoro da; CANDIDO, Erika Donizetti; ZHENG, Yingying; TIYO, Bruna Tiaki; FERREIRA, Arthur Eduardo Fernandes; CORREA-SILVA, Simone; SCAGION, Guilherme Pereira; LEAL, Fabyano Bruno; CHALUP, Vanessa Nascimento; VALERIO, Camila Araujo; SCHMITZ, Gabriela Justamante Handel; CENEVIVA, Carina; CORA, Aline Pivetta; ALMEIDA, Alexandre de; DURIGON, Edison Luiz; OLIVEIRA, Danielle Bruna Leal; PALMEIRA, Patricia; DUARTE, Alberto Jose da Silva; CARNEIRO-SAMPAIO, Magda; OSHIRO, Telma MiyukiWe investigated the anti-SARS-CoV-2 post-vaccine response through serum and salivary antibodies, serum antibody neutralizing activity and cellular immune response in samples from health care workers who were immunized with two doses of an inactivated virus-based vaccine (CoronaVac) who had or did not have COVID-19 previously. IgA and IgG antibodies directed at the spike protein were analysed in samples of saliva and/or serum by ELISA and/or chemiluminescence assays; the neutralizing activity of serum antibodies against reference strain B, Gamma and Delta SARS-CoV-2 variants were evaluated using a virus neutralization test and SARS-CoV-2 reactive interferon-gamma T-cell were analysed by flow cytometry. CoronaVac was able to induce serum and salivary IgG anti-spike antibodies and IFN-gamma producing T cells in most individuals who had recovered from COVID-19 and/or were vaccinated. Virus neutralizing activity was observed against the ancestral strain, with a reduced response against the variants. Vaccinated individuals who had previous COVID-19 presented higher responses than vaccinated individuals for all variables analysed. Our study provides evidence that the CoronaVac vaccine was able to induce the production of specific serum and saliva antibodies, serum virus neutralizing activity and cellular immune response, which were increased in previously COVID-19-infected individuals compared to uninfected individuals.
