- 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.
- Thyroid abnormalities in term infants with fungal sepsis(2016) SILVA, Maria Helena Baptista Nunes Da; ARAUJO, Maria Cristina Korbage De; DINIZ, Edna Maria De Albuquerque; CECCON, Maria Esther Jurfest Rivero; CARVALHO, Werther Brunow DeObjective: To describe thyroid alterations in term newborns (TNB) with fungal sepsis during NICU hospitalization. Method: The study included six TNB that during the clinical and laboratory manifestations of sepsis with positive cultures for fungus showed changes in thyroid hormones, called low T3 syndrome and low T3-T4 syndrome. TNB that could present hormonal changes caused by disease as those born to mothers with thyroid disease, or who had perinatal asphyxia and major surgeries were excluded. Results: Of six TNB with fungal sepsis, five had positive culture for Candida albicans and one had positive culture for Candida tropicalis. Low T3 syndrome was observed in two TNB (50%), while T3-T4 syndrome was observed in other two (100%). The four children progressed to septic shock. Conclusion: Fungal sepsis is becoming more common among newborns admitted to NICU. Thyroid insufficiency could be a marker of disease severity with possible need for hormone supplementation.
