This study was designed to evaluate the angiotensin-converting enzyme insertion/deletion (ACE-I/D), angiotensinogen (AGT) M235T, and angiotensin II receptor type 1 (ATR1) A1166C and type 2 (ATR2) C3123A gene polymorphisms as risk factors for progression to ESRD in patients with VUR.Methods.
Two hundred and forty-six end-stage renal disease (ESRD) patients on peritoneal dialysis and 183 control subjects, all of Chinese origin, were genotyped for the ACE insertion/deletion (I/D) and the AGT M235T gene polymorphisms.
We studied retrospectively the role of angiotensinogen (AGT) M235T, angiotensin converting enzyme (ACE) insertion/deletion (I/D), angiotensin II type 1 receptor (AT1R) A1166C, aldosterone syntase (CYP11B2) -344C/T and intron 2 W/C polymorphisms in conjunction with clinical and biochemical covariables on the rate of progression of renal insufficiency in a group of patients with ESRD of various etiologies.
The results of this study suggest that ACE gene insertion/deletion and angiotensinogen M235T polymorphisms contribute to the increased risk for the development of CRF, but the magnitude of the effect within subsets of patients with specific etiologies of CRF must be evaluated further.
