Background: Kidney disease (KD) is a public health problem worldwide and is an important factor in peripheral vascular disease, arrhythmias, heart failure, acute myocardial infarction, stroke, and angina. Obesity has been indicated as an effective cause of kidney diseases. So, this study aims to use two new strains of Lactobacillus to reduce the metabolic disorders and kidney insufficiency associated with obesity.
Methods: Fifty BALB/c male mice were divided into five groups (control, obesity, obesity pro1, obesity pro2, and obesity mix). The bodyweight, cholesterol profile, urea, and creatinine levels in urine and serum were all measured. Histopathological analysis and expression of Opn, Vim, Ngal, Kim-1, and αKlotho genes for kidney tissues were performed.
Results: The results indicated that body weight, cholesterol profile, urea, and creatinine levels in serum and urine had the lowest significance (P ˂ 0.05) in the obesity mix group and the highest significance in the obesity group. HDL had the highest significance (P ˂ 0.05) in the obesity mix group and the lowest significance (P ˂ 0.05) in the obesity group. Expression of Opn, Vim, Ngal, and Kim-1 genes was the most upregulated in the obesity group compared with the other groups, and there were nonsignificant differences (P > 0.05) between the obesity pro1 and obesity mix groups and the control group. Expression of αKlotho gene was significantly reduced (P ˂ 0.05) in the obesity group compared with the control group.
Conclusion: This study demonstrated that the combination of pro1 and pro2 strains could reduce kidney inflammation and necrosis.
