ÜRİNER SİSTEM ENFEKSİYONLARINDA SHELTERİN PROTEİNLERİ VE AGMATİN İLİŞKİSİ

Abstract: The presence of microorganisms in the kidney, collecting system, or bladder with pyuria and clinical symptoms is called Urinary Tract Infection (UTI). UTI is one of the most common diseases in both nosocomial and community-acquired infections and affects millions of people every year. The clinical types of UTI range from cystitis to sepsis. In this study, we aimed to contribute to the literature by comparing the levels of shelterin proteins and agmatine in the serum of patients diagnosed with cystitis, one of the types of UTI, and healthy volunteers without any known medical disorder, and to bring new approaches to issues such as clinical severity, response to treatment, and pathogenesis of the disease. Methods: In this study, 30 individuals diagnosed with cystitis from UTIs and 30 individuals without any systemic disease participated. Serum agmatine levels were measured by a fluorescence detector using the ultra-high-performance liquid chromatography method (UHPLC). Serum shelterin proteins levels were measured using the ELISA method. Results: When the patients and healthy controls were compared, serum Telomeric Repeat Binding Factor2 (TRF2) levels of the patients were found to be lower than the controls; serum agmatine levels were found to be higher than the controls and statistically significant (p0.05). Conclusion: In conclusion, the statistically significant difference in serum TRF2 and agmatine levels between the groups may be associated with oxidative stress. It is thought that the shortening of telomere lengths may be associated with decreased TRF2 levels.
