Receptor soluble para productos finales de glicación avanzada y perfil lipídico como marcadores de riesgo cardiovascular en niños con obesidad / Soluble receptor for advanced glycation end products and lipid profile ratio as cardiovascular risk markers in children with obesity

RESUMEN

Resumen Introducción: Se ha mostrado que la obesidad está asociada a niveles bajos de la forma soluble del receptor para productos finales de glicación avanzada (sRAGE). Objetivo: Evaluar los niveles de sRAGE y su asociación con el índice lipídico en niños con obesidad. Métodos: Estudio transversal de niños de seis a 11 años de edad con obesidad. Se evaluaron medidas antropométricas, glucosa, perfil lipídico, insulina y sRAGE; también se calculó índice de masa corporal, colesterol total/C-HDL, triglicéridos/glucosa, triglicéridos/C-HDL y HOMA-IR.] Resultados: Se estudiaron 80 niños, 50 % hombres y 50 % mujeres. Las mujeres presentaron mayor perímetro de cintura, HOMA-IR, triglicéridos/C-HDL y triglicéridos/glucosa. No se encontraron diferencias significativas en sRAGE. Al comparar las variables conforme a los terciles de la relación triglicéridos/C-HDL, en el tercil superior se encontraron mayores valores de colesterol total/HDL, triglicéridos/glucosa y sRAGE. Se observó correlación significativa entre sRAGE y HOMA-IR (p < 0.03) en los hombres y entre sRAGE, triglicéridos/C-HDL (p < 0.01) y triglicéridos/glucosa (p < 0.008) en las mujeres. Conclusiones: El sexo femenino mostró más factores de riesgo cardiovascular y mayor sRAGE en el tercil superior de triglicéridos/C-HDL. Se requieren más estudios para probar el posible efecto predictor de mayor riesgo para desarrollar complicaciones metabólicas y cardiovasculares.

ABSTRACT

Abstract Introduction: Obesity has been shown to be associated with low levels of soluble receptor for advanced glycation end products (sRAGE). Objective: To evaluate the levels of sRAGE and its association with the lipid index in children with obesity. Methods: Cross-sectional study of children with obesity aged between six and 11 years. Anthropometric measurements, glucose, lipid profile, insulin and sRAGE were evaluated; body mass index, total cholesterol/high-density cholesterol (TC/HDL-C), triglycerides/glucose (TG/glucose), and triglycerides/HDL-C (TG-HDL-C) ratios and HOMA-IR were also calculated. Results: Eighty children were studied, among which 50% were males and 50% females. Females had higher values for waist circumference, HOMA-IR, and TG/HDL-C and TG/glucose ratios. No significant differences were found for sRAGE. When the variables were compared according to TG/HDL-C ratio tertiles, higher TC/HDL, TG/glucose, and sRAGE values were found at upper tertile. A significant correlation was observed between sRAGE and HOMA-IR (p < 0.03) in males, and between sRAGE and TG/HDL-C (p < 0.01) and TG/glucose ratios (p < 0.008) in females. Conclusions: The female gender showed more cardiovascular risk factors and higher sRAGE at TG/HDL-C upper tertile. Further studies are required to test the possible predictive effect of higher risk for developing metabolic and cardiovascular complications.
