Özet

Background Peripheral arterial diseases (PAD) refer to the arterial diseases other than coronary arteries and the aorta. Atherosclerosis is the major cause of PAD. Renin angiotensin aldosterone system (RAAS)-related genes were associated with cardiovascular diseases. Angiotensin II is the pro-inflammatory, proliferative and vasoconstrictor effector of RAAS in the vascular system. Aims In this study, we aimed to investigate whether the effects of the angiotensinogen (AGT) rs699 (M268T), angiotensin-converting enzyme (ACE) I/D (rs1799752), angiotensin II receptor type 1 (AGTR1) (A1166C) rs5186, and angiotensin II receptor type 2 (AGTR2) rs35474657 variants were associated with PAD etiology due to atherosclerotic involvement of aorta-iliac and femoro-popliteal artery occlusions. Methods AGTrs699,AGTR1rs5186,ACEI/D (rs1799752),AGTR2rs35474657 gene variants were determined by real-time polymerase chain reaction (RT-PCR) in 63 PAD patients (33 femoro-popliteal, 30 aorta-iliac) and 70 healthy controls. Results Although there was no significant relationship in the genotype frequencies ofAGTrs699,AGTR1rs5186,ACEI/D (rs1799752), andAGTR2rs35474657 variants between PAD and control groups (p > 0.05),AGTrs699 TT genotype was significantly associated with fasting glucose (p = 0.023) in PAD patients. Besides, CC genotype of rs699 was significantly related with HDL-cholesterol levels (p = 0.020) in PAD group. Furthermore,AGTR1rs5186 CC genotype carriers demonstrated significantly higher LDL-cholesterol (p = 0.034) and triglycerides levels (p = 0.007). Conclusions This report is the first to show an association between RAAS-related gene variants and their relation with the biochemical characteristics of PAD and suggests that RAAS-associated gene variants may have significant roles in cardiovascular related phenotypes of PAD patients.
