conferenceObject A BIOREPOSITORY AND A CLINICAL-LABORATORIAL DATABASE OF JUVENILE AUTOIMMUNE DISEASES: A RESOURCE FOR THE FUTURE(2013) LIPHAUS, B. L.; PATRAO, D. F. C.; REIS, J. M. A.; FONSECA, F. A. M.; NETO, F. C.; CARNEIRO-SAMPAIO, M. M. S.- Monocyte-to-HDL ratio and non-HDL cholesterol were predictors of septic shock in newborns(2022) FONSECA, Fernanda Andrade Macaferri da da; ESPOSITO, Aline Paulino; SILVA, Maria Helena Baptista Nunes da; NUNES, Valeria Sutti; CAZITA, Patricia Miralda; FERREIRA, Guilherme Silva; CECCON, Maria Esther Jurfest Rivero; CARVALHO, Werther Brunow de; CARNEIRO-SAMPAIO, Magda; PALMEIRA, PatriciaBackground: The association between lipoprotein levels and late-onset neonatal sepsis has shown controversial results. The aims are to assess lipid profile, cytokines, and Monocyte-to-HDL (M/H) ratio as diagnostic and prog-nostic markers for late-onset neonatal sepsis.Methods: This prospective study included 49 septic neonates and 17 controls. Cholesterol (CT), Triglyceride (TG), Very-Low-Density (VLDLc), Low-Density (LDLc), and High-Density Lipoproteins (HDLc) were measured at admis-sion (D0) and on days 3, 7 and 10 to evaluate septic shock outcomes. Cytokines and monocytes were evaluated by flow cytometry.Results: Septic newborns showed higher IL-6 and IL-8 at D0 and CT levels on D7 and on D10, which also presented higher TG, VLDLc and non-HDL cholesterol concentrations than controls. The septic shock group (n = 22) revealed a higher number of male subjects, CRP, IL-6, IL-8 and IL-10 levels, while lower TG, HDLc, monocyte numbers and M/H ratio at admission compared to the non-shock group (n = 27). M/H ratio and non-HDL choles-terol on D0 were risk factors for septic shock (OR = 0.70, 0.49-0.99; OR = 0.96, 0.92-0.99, respectively). Decreasing levels from D0 to D3 of CT (OR = 0.96, 0.93-0.99), VLDLc (OR = 0.91, 0.85-0.98), and non-HDL cholesterol (OR = 0.92, 0.87-0.98) were also predictors of septic shock.Conclusions: Lower M/H ratios and non-HDL cholesterol at admission and decreasing levels of cholesterol, VLDLc and non-HDL cholesterol during a hospital stay are associated with the development of septic shock in newborns with late-onset neonatal sepsis.
- 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.
