Effect of sacubitril/valsartan on cognitive impairment in colchicine-induced Alzheimer's model in rats.
Alzheimer's disease (AD) is a complex neurodegenerative disease. There is epidemiological evidence that heart failure (HF) patients are at higher risk of developing AD, and the impact of sacubitril/valsartan, the first angiotensin receptor-neprilysin inhibitor (ARNI) approved for HF, on cognitive functions is still controversial. To investigate the effect of sacubitril/valsartan on cognitive functions in colchicine-induced AD rat model. Forty adult male Wistar rats were equally allocated into four groups (each of 10 rats): Group I: normal control, Group II: intracerebroventricular injection of colchicine (15 μg/5 μl/bilaterally), Group III: colchicine (15 μg/5 μl/bilaterally, icv) + oral sacubitril/valsartan (100 mg/kg/day) for 25 days, and Group IV: colchicine (15 μg/5 μl/bilaterally, icv) + oral valsartan (50 mg/kg/day) for 25 days. Behavioral assessment was done using Morris water maze and passive avoidance tasks. Biochemically, β-amyloid (1-40 and 1-42) peptides, oxidative stress (malondialdehyde and superoxide dismutase) and inflammatory (tumor necrosis factor-alpha) parameters were measured in hippocampus and prefrontal cortex. Sacubitril/valsartan exaggerated colchicine-induced cognitive impairment in both Morris water maze and passive avoidance tasks and was associated with significant increase in β-amyloid accumulation, oxidative stress, and inflammation versus valsartan. Sacubitril/valsartan caused deleterious effect on cognitive impairment and biochemical alterations in colchicine-induced AD rat model. Hence, special caution should be taken following long-term intake of ARNI on cognitive functions.
