description This study focuses on the complex relationship between positive pressure mechanical ventilation, the pulmonary microbiome, cytokine dynamics, and metabolomic profiles in patients with ventilator-associated pneumonia (VAP). Our research emphasizes how alterations in microbial dynamics are associated with the onset of VAP, underscoring the pivotal role of microbiomes in maintaining respiratory health, particularly in the context of viral respiratory diseases such as COVID-19. We observed significant variations in microbial abundances, which have implications for the development and progression of VAP. Furthermore, our analysis of cytokine dynamics revealed a distinctive immunological modulation in VAP patients, characterized by an enhanced response of neutralizing antibodies coupled with reduced levels of proinflammatory cytokines.

Nuestra investigación destaca cómo las alteraciones en la dinámica microbiana están asociadas con el inicio de VAP, subrayando el papel crucial de los microbiomas en el mantenimiento de la salud respiratoria, especialmente en el contexto de enfermedades respiratorias virales como COVID-19. Observamos variaciones significativas en las abundancias microbianas, lo que tiene implicaciones en el desarrollo y progresión de VAP. Además, el análisis de la dinámica de citoquinas reveló una modulación inmunológica distintiva en pacientes con VAP, caracterizada por una respuesta aumentada de anticuerpos neutralizantes junto con niveles reducidos de citoquinas proinflamatorias.Doctor en BiocienciasDoctorado154 páginasapplication/pdfengUniversidad de La SabanaDoctorado en BiocienciasFacultad de IngenieríaAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Microbioma pulmonarEnfermedades respiratorias virales -- Estudios clínicosCOVID-19Microbiological, inmunological and biochemical features of mechanical ventilation-associated neumonia (MICROVAP) developmentTesis/Trabajo de grado - Doctoradohttp://purl.org/coar/resource_type/c_db06http://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/doctoralThesishttp://purl.org/redcol/resource_type/TDLira-Lucio JA, Falfán-Valencia R, Ramírez-Venegas A, Buendía-Roldán I, RojasSerrano J, Mejía M, Pérez-Rubio G.
