Abstract

BACKGROUND:

Advanced glycation end products (AGEs) are associated with comorbidity and death among patients on hemodialysis (HD). Angiotensin II type 1 receptor blockers (ARBs) can decrease the formation of AGEs in vitro. This study examines the ability of various ARBs to decrease plasma AGE levels in hypertensive patients on HD.

METHODS:

This preliminary randomized prospective study included 24 hypertensive patients on HD who were treated with candesartan (8 mg/day). The patients were randomly assigned to an olmesartan (20 mg/day, n = 12) or a telmisartan (40 mg/day, n = 12) group and followed up 24 weeks. Blood pressure was monitored before each HD session, and plasma pentosidine, N-(epsilon)-carboxymethyl-lysine (CML), serum malondialdehyde-low-density lipoprotein (LDL), high-sensitive CRP, and serum total free radical (TFR) were measured at baseline, and at 4, 12, and 24 weeks.

RESULTS:

Olmesartan was significantly associated with decreased systolic blood pressure compared with telmisartan. After 24 weeks of treatment, plasma pentosidine and CML levels were significantly decreased and serum TFR levels tended to be decreased in the olmesartan group, but remained unchanged in the telmisartan group.

CONCLUSIONS:

These results suggest that olmesartan can help to decrease plasma AGE levels in patients on HD.
