description | OBJECTIVE: The study investigated the effect of angiotensin receptor blockers (ARB) on glucose homeostasis and inflammatory parameters in patients with impaired glucose tolerance (IGT). RESEARCH DESIGN AND METHODS: We prospectively studied the insulin sensitivity index (ISI) and homeostasis model assessment–insulin resistance (HOMA-IR) in 13 obese males with IGT and in 13 matched control subjects with normal glucose tolerance (NGT) during hyperglycemic testing over 90 min. Adiponectin, retinol-binding protein 4 (RBP4), and high-sensitive C-reactive protein (hsCRP) were analyzed. Measurements were performed at baseline and after a 4-week treatment with 160 mg/day valsartan. The results of the IGT and NGT groups were compared. RESULTS: At baseline, HOMA-IR (IGT 4.1 ± 3 vs. NGT 2.3 ± 1.0, P < 0.01), hsCRP (IGT 3.9 ± 1.9 vs. NGT 1.8 ± 1 mg/l, P < 0.05), and RBP4 (IGT 27.1 ± 2.1 vs. NGT 24.0 ± 2.0 ng/ml, P < 0.05) were significantly higher, whereas ISI (IGT 1.5 ± 0.9 vs. NGT 1.8 ± 1.2, P < 0.05) and plasma adiponectin (IGT 3.2 ± 0.9, NGT 5.2 ± 2.4 μg/ml, P < 0.05) were significantly lower in the IGT group compared with the NGT group. Under ARB, there was an increase in both groups of adiponectin (IGT 4.1 ± 1.9 μg/ml, NGT 6.3 ± 2.9 μg/ml, P < 0.05) and an increase in ISI (IGT 1.5 ± 0.9 to 2.3 ± 1 μg/ml, NGT 1.8 ± 1 to 2.5 ± 2 μg/ml, P < 0.05). HOMA-IR (4.1 ± 3 to 2.6 ± 2; P < 0.01), hsCRP (3.9 ± 1.9 to 1.8 ± 1 mg/l, P < 0.05), and RBP4 (27.1 ± 2.1 to 22.1 ± 1.8 ng/ml, P < 0.01) decreased significantly in the IGT group. CONCLUSIONS: Insulin sensitivity and associated inflammatory factors improve under ARB in IGT patients. |
