Abstract

ALMARZA, Johan. Is a non-alcoholic fatty liver an inflammatory component of the metabolic syndrome?. Perspect Nut Hum [online]. 2010, vol.12, n.2, pp.163-175. ISSN 0124-4108.

Objective: Integrate components that correlate insulin-resistance in the development of non-alcoholic fatty liver and the molecular mechanisms involved in the pathophysiology, diagnostic methods and clinical implications. Methods and materials: A systematic search was conducted of articles from 1990 to 2010, comprised primarily of a period from October 2009 to December 2010, using international data bases like PubMed, ScienceDirect and Ovid. The research for information related to Latin America, including Colombia and Venezuela, was done in Lilacs and Scielo. Medical Subject Headings (Mesh) and each one of the said services were used in determining choice of terms. Results and conclusions: Inflammatory mediators (adipokines), oxidative (reactive oxygen species) and metabolic (free fatty acids) responsible for the natural history of the SM are relative to the development of the non-alcoholic fatty liver (HGNA); therefore the identification of this pathological component through the biochemical methods and relevant ultrasound, is of the utmost importance. Gradual weight loss, increased physical activity, dietary modifications increase the expression of enzymes peroxisomes of the beta oxidation of fatty acids, and prevent their subsequent cytoplasmic accumulation.

Keywords : fatty liver; metabolic syndrome; oxidative stress.
