Effect of enos gene polymorphism on the course of early onset bacterial infections in premature infants.

OBJECTIVE

The aim of the study was to analyze the associations between 4a/4b polymorphism of the eNOS gene and impaired systemic hemodynamics in premature infants with early neonatal sepsis.

PATIENTS AND METHODS

Materials and methods: We conducted a prospective cohort study, which included 120 premature babies with early neonatal sepsis, in 57 children the course of the disease was accompanied by arterial hypotension (AH) and in 61 children - not. In children of both groups, genotyping was performed to determine 4a/4b polymorphism of the eNOS gene.

RESULTS

Results: It was shown that the heart rate, blood pressure, hourly diuresis, the level of total nitrates and nitrites in the urine, as well as a number of echocardioscopic and dopplerometric indicators in children with different eNOS gene genotypes are not different.

CONCLUSION

Conclusions: There is no effect of 4a/4b polymorphism of the eNOS gene on the occurrence of hemodynamic disturbances in premature infants with sepsis.
