RESUMEN

OBJECTIVE: To assess factors associated with long-term neuropsychiatric outcomes, including biomarkers measured after discharge from the intensive care unit. METHODS: A prospective cohort study was performed with 65 intensive care unit survivors. The cognitive evaluation was performed through the Mini-Mental State Examination, the symptoms of anxiety and depression were evaluated using the Hospital Anxiety and Depression Scale, and posttraumatic stress disorder was evaluated using the Impact of Event Scale-6. Plasma levels of amyloid-beta (1-42) [Aß (1-42)], Aß (1-40), interleukin (IL)-10, IL-6, IL-33, IL-4, IL-5, tumor necrosis factor alpha, C-reactive protein, and brain-derived neurotrophic factor were measured at intensive care unit discharge. RESULTS: Of the variables associated with intensive care, only delirium was independently related to the occurrence of long-term cognitive impairment. In addition, higher levels of IL-10 and IL-6 were associated with cognitive dysfunction. Only IL-6 was independently associated with depression. Mechanical ventilation, IL-33 levels, and C-reactive protein levels were independently associated with anxiety. No variables were independently associated with posttraumatic stress disorder. CONCLUSION: Cognitive dysfunction, as well as symptoms of depression, anxiety, and posttraumatic stress disorder, are present in patients who survive a critical illness, and some of these outcomes are associated with the levels of inflammatory biomarkers measured at discharge from the intensive care unit.

RESUMO Objetivo: Avaliar os fatores associados aos desfechos neuropsiquiátricos de longo prazo, incluindo biomarcadores, medidos após a alta da unidade de terapia intensiva. Métodos: Foi realizado um estudo de coorte prospectivo com 65 sobreviventes de unidades de terapia intensiva. A avaliação cognitiva foi realizada por meio do Miniexame do Estado Mental; os sintomas de ansiedade e depressão foram avaliados por meio da Escala Hospitalar de Ansiedade e Depressão, e o transtorno de estresse pós-traumático foi avaliado pela Escala de Impacto do Evento-6. Os níveis plasmáticos de beta amiloide (1-42), beta amiloide (1-40), interleucina 10, interleucina 6, interleucina 33, interleucina 4, interleucina 5, fator de necrose tumoral alfa, proteína C-reativa e fator neurotrófico derivado do cérebro foram medidos na alta da unidade de terapia intensiva. Resultados: Das variáveis associadas à terapia intensiva, apenas o delirium foi relacionado de forma independente à ocorrência de comprometimento cognitivo de longo prazo. Além disso, níveis mais altos de interleucina 10 e interleucina 6 foram associados à disfunção cognitiva. Apenas a interleucina 6 foi associada de forma independente à depressão. A ventilação mecânica, os níveis de interleucina 33 e os níveis de proteína C-reativa foram associados de forma independente à ansiedade. Nenhuma variável foi associada de forma independente ao transtorno de estresse pós-traumático. Conclusão: A disfunção cognitiva, bem como os sintomas de depressão, ansiedade e transtorno de estresse pós-traumático, estão presentes em pacientes que sobrevivem a uma doença grave, e alguns desses desfechos estão associados aos níveis de biomarcadores inflamatórios medidos na alta da unidade de terapia intensiva.

RESUMEN

Sepsis is defined as a life-threatening organ dysfunction caused by an inappropriate host response to infection. The presence of oxidative stress and inflammatory mediators in sepsis leads to dysregulated gene expression, leading to a hyperinflammatory response. Environmental conditions play an important role in various pathologies depending on the stimulus it presents. A standard environment condition (SE) may offer reduced sensory and cognitive stimulation, but an enriched environment improves spatial learning, prevents cognitive deficits induced by disease stress, and is an important modulator of epigenetic enzymes. The study evaluated the epigenetic alterations and the effects of the environmental enrichment (EE) protocol in the brain of animals submitted to sepsis by cecal ligation and perforation (CLP). Male Wistar rats were divided into sham and CLP at 24 h, 72 h, 10 days and 30 days after sepsis. Other male Wistar rats were distributed in a SE or in EE for forty-five days. Behavioral tests, analysis of epigenetic enzymes:histone acetylase (HAT), histone deacetylase (HDAC) and DNA methyltransferase (DNMT), biochemical and synaptic plasticity analyzes were performed. An increase in HDAC and DNMT activities was observed at 72 h, 10 days and 30 days. There was a positive correlation between epigenetic enzymes DNMT and HDAC 24 h, 10 days and 30 days. After EE, HDAC and DNMT enzyme activity decreased, cognitive impairment was reversed, IL1-ß levels decreased and there was an increase in PSD-95 levels in the hippocampus. Interventions in environmental conditions can modulate the outcomes of long-term cognitive consequences associated with sepsis, supporting the idea of the potential benefits of EE.

RESUMEN

OBJECTIVE: To examine the effectiveness of stratification to identify and target antioxidant therapy for animal models of lethal sepsis and in patients who develop sustained hypotension. METHODS: Rats were subjected to sepsis induced by cecal ligation and puncture. Animals were divided into two groups: those with high and low plasma levels of interleukin-6. Following stratification, N-acetylcysteine plus deferoxamine or saline was administered to animals starting 3 and 12 hours after surgery. N-Acetylcysteine plus deferoxamine or placebo was administered within 12 hours of meeting the inclusion criteria in hypotensive patients. RESULTS: N-Acetylcysteine plus deferoxamine increased survival in the cecal ligation and puncture model when administered 3 and 12 hours after sepsis induction. When dividing animals that received antioxidants using plasma interleukin-6 levels, the protective effect was observed only in those animals with high IL-6 levels. The antioxidant effect of N-acetylcysteine + deferoxamine was similar in the two groups, but a significant decrease in plasma interleukin-6 levels was observed in the high-interleukin-6-level group. Compared with patients treated with antioxidants in the low-interleukin-6 subgroup, those in the high-interleukin-6 subgroup had a lower incidence of acute kidney injury but were not different in terms of acute kidney injury severity or intensive care unit mortality. CONCLUSION: Targeting antioxidant therapy to a high inflammatory phenotype would select a responsive population.
