RESUMO

Introdução: Pacientes com quadro de sepse ocupam 30% dos leitos das Unidades de Terapia Intensiva (UTI) no Brasil, com letalidade de 55%, impactando diretamente a saúde e economia brasileiras. A Lipoproteína de Alta Densidade (HDL) expressa funções imunomoduladoras, previne liberação de citocinas e neutraliza toxinas bacterianas. Dosagens de HDL abaixo de 20mg/ dL em pacientes sépticos estão associadas a maior mortalidade. Objetivos: Analisar a correlação dos níveis séricos de HDL com o prognóstico de mortalidade em pacientes sépticos admitidos na UTI do Hospital Universitário de Canoas (HU). Objetivos específicos incluem a correlação dos níveis de HDL com marcadores clássicos de gravidade lactato, proteína C reativa (PCR), albumina e escore SOFA. Métodos: Estudo observacional analítico de coorte prospectiva, que incluiu 292 pacientes admitidos na UTI do HU diagnosticados com Sepse, conforme diretriz SEPSIS3: ≥ 2 pontos no SOFA (Sequential Organ Failure Assesment Score) no período de 1º de agosto de 2019 a 30 de agosto de 2020. Resultados: Óbitos foram estatisticamente mais frequentes nos indivíduos que apresentaram HDL <20mg/dL (47,5%) do que naqueles com valores de HDL ≥20mg/dL (32,80%). Conclusão: Embora não haja na literatura relação de causalidade entre baixos níveis de HDL e sepse, é verificado na literatura e corroborado neste estudo que pacientes sépticos com níveis baixos de HDL tiveram pior desfecho quando comparados a pacientes com níveis normais. Também foi encontrada associação significativa de maiores níveis séricos de PCR e lactato com baixos níveis de HDL, sendo esses marcadores de pior prognóstico na sepse.

Introduction: Septic patients occupy 30% of the beds in the Brazilian intensive care units (ICU), with a mortality rate of 55%, strongly impacting Brazilian health and the economy. High-density lipoprotein (HDL) has immunomodulatory functions, prevents cytokine release, and neutralizes bacterial toxins. HDL levels below 20mg/dL in septic patients are associated with higher mortality. Objectives: To analyze the correlation of serum HDL levels with mortality prognosis in septic patients admitted to the Canoas University Hospital (Hospital Universitário de Canoas [HU]) ICU. The specific objectives include the correlation of HDL levels with classic markers of severity - lactate, C-reactive protein (CRP), albumin, and SOFA score. Methods: an observational analytical prospective cohort study, which included 292 patients admitted to the HU ICU diagnosed with sepsis - as per SEPSIS-3 guideline: ≥ 2 points in SOFA (Sequential Organ Failure Assessment Score) - in the period from August 1, 2019, to August 30, 2020. Results: deaths were statistically more frequent in individuals who had HDL <20mg/dL (47.5%) than in those with HDL values ≥ 20mg/dL (32.80%). Conclusion: Although there is no causal relationship, in the literature, between low HDL levels and sepsis, it is verified in the literature and corroborated in this study that septic patients with low HDL levels had worse outcomes compared to patients with normal levels. It was also found a significant association of higher serum levels of CRP and lactate with low HDL levels, these being markers of worse prognosis in sepsis.

RESUMO

BACKGROUND: The finding of new biomarkers is needed to have a better sub-classification of primary renal tumors (RCC) as well as more reliable predictors of outcome and therapy response. In this study, we evaluated the role of circulating FGF21, an endocrine factor, as a diagnostic and prognostic biomarker for ccRCC. MATERIALS AND METHODS: Serum samples from healthy controls (HC), clear cell and chromophobe RCC cancer patients were obtained from the serum biobank "Biobanco Público de Muestras Séricas Oncológicas" (BPMSO) of the "Instituto de Oncología "Ángel H. Roffo". Serum FGF21 and leptin were measured by ELISA while other metabolic markers were measured following routinely clinical procedures. RESULTS: One of our major findings was that FGF21 levels were significantly increased in ccRCC patients compared with HC. Moreover, we showed an association between the increased serum FGF21 levels and the shorter disease free survival in a cohort of 98 ccRCC patients, after adjustment for other predictors of outcome. CONCLUSION: Our results suggest that higher FGF21 serum level is an independent prognostic biomarker, associated with worse free-disease survival.
