ABSTRACT

Objective:

The objective of this study was to establish the role of the TLR-4 gene polymorphisms in individuals in risk of developing ACS.

Methods:

The study included 457 Mexican patients with ACS and 283 control individuals. The TLR-4 Asp299Gly and TLR-4 Thr399Ile single nucleotide polymorphisms were genotyped using 5' exonuclease TaqMan genotyping assays on an 7900HT Fast real-time PCR system according to manufacturer's instructions (Applied Biosystems, Foster City, USA).

Results:

The results obtained in this study showed that the frequency of the two polymorphisms (TLR-4 Asp299Gly and TLR-4 Thr399Ile) studied were similar between patients with ACS and healthy controls. Multiple logistic regression analysis showed that the largest risk factor for ACS development was given by smoking (11.88-fold increased risk), hypertension (4.32-fold increased risk), type II diabetes (3.44-fold increased risk), gender (2.32-fold increased risk), and dyslipidemia (1.52-fold increased risk).

Conclusion:

The Asp299Gly and Thr399Ile polymorphisms were not associated with susceptibility to ACS in the Mexican population.
RESUMEN

Objetivo:

El objetivo de este estudio fue establecer el papel de los polimorfismos del gen TLR-4 en individuos en riesgo de desarrollar síndrome coronario agudo (SCA).

Métodos:

El estudio incluyó a 457 pacientes mexicanos con SCA y 283 individuos como grupo control. Los polimorfismos de un solo nucleótido TLR-4 Asp299Gly y TLR-4 Thr399Ile fueron determinados usando ensayos TaqMan 5' exonucleasa en un equipo tiempo real 7900HT (Fast real-time PCR system) de acuerdo con instrucciones del fabricante Applied Biosystems, Foster City, EE.UU.

Resultados:

Los resultados obtenidos mostraron que las frecuencias de los 2 polimorfismos (TLR-4Asp299Gly y TLR-4 Thr399Ile) estudiados fueron similares entre pacientes con SCA e individuos control. No obstante, el análisis de regresión logística mostró que los factores de mayor riesgo para desarrollar SCA se debieron a tabaquismo (incrementa 11.88 veces el riesgo), hipertensión (incrementa 4.32 veces el riesgo), diabetes tipo 2 (incrementa 3.44 veces el riesgo), género (incrementa 2.32 veces el riesgo), y la dislipidemia (incrementa 1.52 veces el riesgo).

Conclusión:

Determinamos que los polimorfismos Asp299Gly y Thr399Ile no se asocian con la susceptibilidad al SCA en la población mexicana.
