IntroductionPatients with Coronavirus Disease 2019 (COVID-19) frequently experience a hyperinflammatory syndrome, that leads to unfavorable outcomes. This condition resembles Secondary Hemophagocytic Lymphohistiocytosis (sHLH) described in neoplastic, rheumatic and other infectious diseases. However, it has not been prospectively studied on these patients. A scoring system (HScore) has been validated for sHLH, and recently proposed to evaluate hyperinflammation in COVID-19.Methods143 patients aged ≥18 years admitted because of COVID-19 were enrolled in a prospective, single-center, cohort study. HScore was calculated within the 72 hours since admission. The incidence of sHLH during hospitalization was evaluated. Additionally, the relationship between HScore ≥130 points and either the requirement of mechanical ventilation or 60-days mortality was explored.ResultsThe median age of enrolled patients was 57 (21-100), and 63.6% were male. The median HScore was 96 (33-169). One patient was diagnosed with sHLH (incidence 0,7%), due to a HScore of 169. After adjusting for age, sex, comorbidities and obesity, HScore ≥130 was independently associated with the composite clinical outcome (HR 2.13, p=0.022).ConclusionsHLH is not frequent among COVID-19 patients. HScore can efficiently predict the risk for poor outcomes.
Objetivo: caracterizar los episodios de bacteriemias, los microorganismos causantes y sus patrones de sensibilidad, en pacientes atendidos en el Instituto del Cáncer SOLCA-Cuenca, Ecuador. Metodología: se utilizó un diseño descriptivo. El estudio se enfocó en todos los episodios de bacteriemias ocurridos en el periodo 2011-2016 verificados mediante hemocultivos. Las variables estudiadas fueron edad y sexo de los pacientes en los que se produjo la bacteriemia; tipo de tumor, microorganismo, tiempo de positivización y perfil de resistencia. Resultados: se identificaron 318 episodios. El 66.8% de los microorganismos aislados fueron bacterias gramnegativas y el 33.2% grampositivas; los más prevalentes fueron Escherichia coli 37.3%, Staphylococcus aureus 17.9%, Klebsiella.spp 9.3%, Estafilococos coagulasa negativa 7.2% y Pseudomonas aeruginosa 5.1%. En los cocos grampositivos, la meticilino resistencia fue de 40% en Staphylococcus aureus.y 67% en Staphylococcus coagulasa negativa; Escherichia coli y Klebsiella pneumoniae fueron resistentes a cefalosporinas de tercera generación en un 29% y 47%, respectivamente, compatibles con el fenotipo de beta-lactamasa de espectro extendido; la resistencia a quinolonas fue 35% y 50% respectivamente. Conclusiones: las bacterias gramnegativas fueron los microorganismos más prevalentes en este estudio, principalmente enterobacterias, con una importante resistencia a los antibióticos ensayados.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
