Frequency of TGF-β and IFN-γ Genotype as Risk Factors for Acute Kidney Injury and Death in Intensive Care Unit Patients
Genetic variations in TGF-β and IFN-γ may interfere with proinflammatory cytokine production and, consequently, may be involved with inflammatory diseases, as acute kidney injury (AKI). We considered that genetic polymorphisms of these cytokines may have a crucial role in the outcome of critically i...

Sumario: | Genetic variations in TGF-β and IFN-γ may interfere with proinflammatory cytokine production and, consequently, may be involved with inflammatory diseases, as acute kidney injury (AKI). We considered that genetic polymorphisms of these cytokines may have a crucial role in the outcome of critically ill patients. To investigate whether the genetic polymorphisms of rs1800470 (codon 10 T/C), rs1800471 (codon 25 C/G) from the TGF-β, and rs2430561 (+874 T/A) from IFN-γ may be a risk factor for ICU patients to the development of AKI and/or death. In a prospective nested case-control study, were included 139 ICU patients who developed AKI, 164 ICU patients without AKI, and 244 healthy individuals. We observed a higher frequency to T/A genotype for IFN-γ (intermediate producer phenotype) and higher frequency of TT GG and TC GG genotype (high producer) for TGF-β polymorphism in overall population. However, these polymorphisms have not been shown as a predictor of risk for AKI and death. We found an increased prevalence of high and intermediate producer phenotypes from TGF-β and IFN-γ, respectively, in patients in ICU setting. However, the studied genetic polymorphism of the TGF-β and IFN-γ was not associated as a risk factor for AKI or death in our population. |
