Relación entre los niveles de interleucina 6 y depresión en pacientes afectados por Covid-19 / Interleukin 6 and depression in patients affected by Covid-19

Introducción: El incremento de citocinas centrales resultante de infecciones produce cambios neuronales. La Covid-19 permite estudiar los síntomas depresivos en un estrés sostenido y su relación con mecanismos moleculares.ObjetivosValorar la correlación entre niveles de IL-6, IL-1β y TNF-α y sintomatología depresiva. Caracterizar los cuadros depresivos presentes.MétodosEstudio observacional. Se incluyeron pacientes ingresados por Covid-19 mayores de 60años con una determinación de interleucinas. Se utilizó la Escala de depresión geriátrica de Yesavage (GDS), asociándose cada ítem con un neurotransmisor.ResultadosSe incluyeron 27 pacientes. No encontramos correlación entre los niveles de IL-6 y la puntuación de la escala GDS (rho=0,204; IC95% −0,192 a 0,543); ni con los niveles de IL-1β (rho=−0,126; IC95% −0,490 a 0,276); ni de TNF-α (rho=−0,033; IC95% −0,416 a 0,360). Tres pacientes (11,1%) presentaron una puntuación compatible con cuadro depresivo. Se asoció a déficit de noradrenalina y serotonina.ConclusionesNo hallamos correlación entre los niveles de IL-6, IL-1β y TNF-α con la puntuación en la GDS. La sintomatología depresiva presenta características similares a las depresiones vasculares. (AU)

Introduction: Rise of central cytokines resulting from infections produces neuronal changes. Covid-19 allows the study of depressive symptoms in sustained stress and its relationship with molecular mechanisms.ObjectivesTo assess correlation between IL-6, IL-1β and TNF-α and depressive symptoms. Characterize the depressive symptoms present.MethodsObservational study. Patients admitted for Covid-19 older than 60 years with a interleukin determination were included. The Yesavage Geriatric Depression Scale (GDS) was used, associating each item with a neurotransmitter.Results27 patients included. We did not find correlation between IL-6 levels and the GDS scale score (rho=0.204; 95% CI −0.192 to 0.543); with IL-1β levels (rho=−0.126; 95% CI −0.490 to 0.276); nor of TNF-α (rho=−0.033; 95% CI −0.416 to 0.360). 3 patients (11.1%) presented score compatible with depressive disorder. It was associated with a deficiency of noradrenaline and serotonin.ConclusionsWe found no correlation between the levels of IL-6, IL-1β, and TNF-α with the GDS score. Depressive symptomatology is similar to vascular depressions. (AU)

Interleukin 6 and depression in patients affected by Covid-19.

INTRODUCTION: Rise of central cytokines resulting from infections produces neuronal changes. Covid-19 allows the study of depressive symptoms in sustained stress and its relationship with molecular mechanisms. OBJECTIVES: To assess correlation between IL-6, IL-1ß and TNF-α and depressive symptoms. Characterize the depressive symptoms present. METHODS: Observational study. Patients admitted for Covid-19 older than 60 years with a interleukin determination were included. The Yesavage Geriatric Depression Scale was used, associating each item with a neurotransmitter. RESULTS: 27 patients included. We did not find correlation between IL-6 levels and the GDS scale score (rho = 0.204; 95% CI -0.192 to 0.543); with IL-1ß levels (rho = -0.126; 95% CI -0.490 to 0.276); nor of TNF-α (rho = -0.033; 95% CI -0.416 to 0.360). 3 patients (11.1%) presented score compatible with depressive disorder. It was associated with a deficiency of Noradrenaline and Serotonin. CONCLUSIONS: We found no correlation between the levels of IL-6, IL-1ß, and TNF-α with the GDS score. Depressive symptomatology is similar to vascular depressions.
