Abstract

Objective: To evaluate the TLR2 Arg753Gln polymorphism as a possible risk marker for sepsis development.

Materials and Methods: Association study which included 183 unrelated Venezuelan individuals, divided into two groups: patients with sepsis (n = 50) hospitalized in the emergency area of ??the Central Hospital of the Venezuelan Institute of Social Security “Dr. Miguel Pérez Carreño”, and apparently healthy individuals (n = 133). The TLR2 Arg753Gln polymorphism was determined using the polymerase chain reaction technique with specific sequence primers. 

Results: A higher death rate was observed among the group of patients with the SOFA scale range between 6-9 compared to the group of patients with the SOFA scale range between 0-5 (OR: 8.5; 95% CI: 2.33-30.90, p = 0.000357). The Arg753Gln polymorphism of the TLR2 gene is absent in patients diagnosed with sepsis.

Conclusion: It was verified that the SOFA scale is a useful system to predict the mortality rate associated with sepsis. The absence of the Arg753Gln polymorphism of the TLR2 gene among the group of patients with sepsis diagnosis and its low frequency in apparently healthy individuals suggests the rarity of this polymorphism in the Venezuelan population. Consequently, it is necessary to increase the size of the sample to be able to evaluate whether it can be considered as a risk marker for sepsis development in our population.
