Biomarcadores en el síndrome metabólico y su correlación con la osteocalcina sérica

Abstract

Introducción: La osteocalcina aumenta la secreción de insulina, la insulino-sensibilidad, por intermedio de la secreción de adiponectina y el consumo energético; disminuye la glucosa plasmática y la masa corporal y estimula las células beta pancreáticas. Recientes estudios parecen demostrar una regulación mutua entre el metabolismo energético y el hueso a través de la osteocalcina. Objetivos: Evaluar si existe correlación entre los niveles séricos de osteocalcina con marcadores de insulinorresistencia de inflamación y otros marcadores metabólicos en una población adulta con síndrome metabólico (SM). Materiales y métodos: Se incluyeron 95 pacientes: 58 mujeres y 37 hombres con una media de edad de 51,5 ± 8,5 y 53,6 ± 9,3 años, respectivamente, con diagnósticos de SM, según criterios del National Cholesterol Education Program. Se practicó a cada paciente una extracción de sangre venosa con 12 horas de ayuno. Se dosaron los siguientes analitos: osteocalcina, glucemia basal, insulina, colesterol total, colesterol HDL, colesterol LDL, triglicéridos TG, hemoglobina glicosilada, proteína C reactiva, apoproteína A1, apoproteína B, leptina e interleuquina 6. Resultados: los valores de osteocalcina mostraron correlación negativa con: glucemia basal (r = -0,29, p ≤ 0,005), TG (r = -0,24, p ≤ 0,005), HbA1c (r = -0,23, p ≤ 0,005) e Índice TG/HDLc (r = -0.23, p ≤ 0,005) en toda la población. Conclusiones: Los niveles bajos de osteocalcina se correspondieron con elevación de indicador de insulinorresistencia y con parámetros de mal control metabólico; mostraron también una asociación inversa de valores de osteocalcina sérica con el riesgo de aparición de eventos metabólicos adversos.
