EOSINOFILIA, UN BIOMARCADOR DE IMPORTANCIA EN LA ENFERMEDAD PULMONAR OBSTRUCTIVA CRÓNICA (EPOC).

Abstract

Evidence supports that the use of biomarkers to guide COPD treatment is necessary to improve patients' quality of life; However, it does not become an easy task since it brings together different characteristics such as its reliability, its ease of measurement and its relevance within the different EPOC processes. Objective: Determine the importance of eosinophilia as a biomarker in Chronic Obstructive Pulmonary Disease (COPD). Methodology: It is a retrospective descriptive study of a bibliographic nature. An exhaustive search of scientific articles was carried out, such as bibliographic review, cohort and control studies, systematic and bibliographic review, and meta-analysis, in the languages of Spanish and English, using medical information databases; Scielo, Pubmed, Elsevier, Scopus, Google Scholar and Medline. Results: Through the application of inclusion and exclusion criteria, 7 articles have been collected that gather the most relevant information about eosinophilia as a biomarker in Chronic Obstructive Disease. Conclusions: Several authors agree that, although eosinophilia cannot be taken as a reference for diagnosis and determining the severity of COPD symptoms, it can be used to guide treatment and as a predictor of exacerbations in the different stages of the pathology.
