SAN MIGUEL-SIMBRON, José L. Echography of thymus in childhood: a useful tool to evaluate the immune response in childhood growth and development. Cuad. - Hosp. Clín. [online]. 2021, vol.62, n.2, pp.113-122. ISSN 1562-6776.

Abstract Concepts of immunocompetence and its relationship with nutrition in children are presented, describing comprehensive physiological aspects. Immunological aspects are also described, which allow to interpret the mechanisms of the immune response, highlighting physiological concepts and criteria. A malnourished child presents immunological alterations, and these can be identifiedas deficiencies with a cellular predominance, and with a humoral predominance. The importance of the Neuro-immuno-endocrinological axis as an integrator of physiological responses is highlighted. The purpose of this work is aimed at identifying the tools that allow the study of the immune system in our context, with special emphasis on ultrasound of the thymus, as it is a useful tool to evaluate the immune system in children with altered nutritional status, mild or moderate.

Palavras-chave : Immunity; malnutrition; indicators of the immune system; ultrasound of the thymus in children.
