POLYMORPHISMS WITHIN INNATE IMMUNE RESPONSE, CALCIUM METABOLISM AND LIPID METABOLISM ARE PREDICTORS OF INFECTIVE ENDOCARDITIS
Infective endocarditis (IE) is a septic inflammation of the endocardium generally caused by bacteria. Despite certain advances in treatment, case fatality rate and mortality of IE are still relatively high, particularly in high-risk groups. This requires the development of novel efficient preventive...

Infective endocarditis (IE) is a septic inflammation of the endocardium generally caused by bacteria. Despite certain advances in treatment, case fatality rate and mortality of IE are still relatively high, particularly in high-risk groups. This requires the development of novel efficient preventive approaches; one of them is a personalized medicine. Recognition of microbial patterns, cytokine and acute phase responses, hemostasis features and alterations in plasma lipid and calcium profile all have been reported to affect pathogenesis and clinical course of IE. We hypothesized that inherited genomic variation in the abovementioned pathways may determine individual susceptibility to IE. Having recruited 124 patients with IE and 300 age-, sex-, and ethnicity-matched healthy controls, we profiled their genomic DNA for 35 functionally significant polymorphisms within the 22 selected genes involved in pathways mentioned above, with the further genetic association analysis. Genotyping was performed using TaqMan allelic discrimination assay while statistical analysis was carried out utilizing SNPStats, a web tool for genetic association analysis. We found that the G/A genotype of the rs1143634 polymorphism within the IL1B gene, the G/T genotype of the rs3212227 polymorphism within the IL12B gene, the A/G genotype of the rs1130864 polymorphism within the CRP gene, and the G allele of the rs1801197 polymorphism within the CALCR gene are associated with a decreased risk of IE whereas the T/T genotype of the rs1205 polymorphism within the CRP gene is associated with a higher risk of IE.
