Abstract | BACKGROUND: METHODS: RESULTS: After 12 weeks, urine and blood were obtained and blood pressure measured. Glucose concentrations were increased and similar in all diabetic groups. Telmisartan alone reduced systolic blood pressure by 5.9 mmHg versus diabetic controls (111.2 ± 2.3 mmHg vs 117.1 ± 2.2 mmHg; mean ± SEM; P=0.071). Combined treatment significantly reduced albuminuria compared with diabetic controls (71.7 ± 15.3 µg/24 h vs. 170.8 ± 34.2 µg/24 h; P=0.017), whereas the effects of single treatment with either telmisartan (97.8 ± 26.4 µg/24 h) or linagliptin (120.8 ± 37.7 µg/24 h) were not statistically significant. DPP-4 inhibition, alone and in combination, led to significantly lower plasma osteopontin levels compared with telmisartan alone. Histological analysis revealed reduced glomerulosclerosis after Linagliptin alone and in combination with telmisartan in comparison to non treated diabetic animals (p<0.01 and p<0.05). Kidney malonaldehyde immune-reactivity, a marker of oxidative stress, was significantly lower in animals treated with linagliptin. CONCLUSIONS:
