Resumen
Objetivos: Analizar la longitud telomérica (LT) como biomarcador del riesgo y la progresión de enfermedades metabólicas. Evaluar la LT de acuerdo con el número de alteraciones metabólicas y factores de riesgo ambientales. Materiales y Métodos: Se realizó un estudio transversal en individuos categorizados de la siguiente manera : con obesidad metabólicamente sanos (OMS); obesidad y síndrome metabólico (OSM) y un grupo control normopeso (NP). Se hicieron determinaciones bioquímico-clínicas y antropométricas y se infomaron presencia de factores de riesgo del estilo de vida y enfermedades preexistentes. La LT absoluta se determinó en ADN de sangre periférica por PCR cuantitativa. El análisis estadístico se realizó con SPSS versión 20.0 con p<0.05. Resultados: La menor LT se asoció a la presencia de anormalidades del SM y al aumento progresivo del número de componentes(p<0.001). Los OMS presentaron una LT significativamente menor que los NP (p=0.034) y mayor que los OSM (p=0.004). La menor LT se asoció con la mayor cantidad de años de ser fumador (p=0.003). Por último, el tercil más bajo de LT se asoció con mayor riesgo de presentar circunferencia de cintura aumentada (OR=2.13; p<0.001), triglicéridos altos (OR=1.68; p=0.034), dislipidemia (OR=1.86; p=0.039), obesidad (OR=2.41; p<0.001) y SM (OR=2.12; p<0.001). Conclusión: la LT puede resultar un biomarcador útil de riesgo y progresión de enfermedades metabólicas, como la enfermedad cardiovascular y la DT2.
Objectives: To analyze telomere length (LT) as a biomarker of risk and progression of metabolic diseases and to evaluate the TL according to the number of metabolic alterations and environmental risk factors. Materials and Methods: We performed a cross-sectional study of 1006 individuals categorized into: metabolically healthy individuals with obesity (OMS); obesity and metabolic syndrome (OSM) and a normal weight control group (NP). Biochemical-clinical and anthropometric determinations were made and the presence of lifestyle risk factors and pre-existing diseases were self-reported. The absolute LT in peripheral blood DNA was determined by quantitative PCR. Statistical analysis was performed with SPSS v20.0 with p<0.05. Results: A lower TL was associated with the presence of metabolic syndrome abnormalities and the progressive increase in the number of components (p<0.001). The OMS individuals presented a significantly lower TL than the NP individuals (p=0.034) and higher than the OSM ones (p=0.004). The lowest LT was associated with the highest number of years of smoking (p=0.003). Finally, the lowest tercile of TL was associated with a higher risk of presenting increased waist circumference (OR=2.13; p<0.001), high triglycerides (OR=1.68; p=0.034), dyslipidemia (OR=1.86; p= 0.039), obesity (OR=2.41; p<0.001) and metabolic syndrome (OR=2.12; p<0.001). Conclusion: LT may be a useful biomarker of risk and progression of metabolic diseases such as cardiovascular disease and type 2 diabetes.
