AI Technical Summary

Benefits of technology

The present invention relates to a composition containing Bifidobacteria and Lactobacilli that can be used to treat various diseases or conditions in mammals, including humans. The ratio of Bifidobacteria to Lactobacilli can vary depending on the desired effect, but typically falls between 1:1. The Bifidobacteria and Lactobacilli can be administered to mammals in various ways, such as through food or supplements. The invention is particularly useful for mammals ingesting a high-fat diet.

Problems solved by technology

This causes a need for abnormally high amounts of insulin and diabetes develops when the beta cells cannot meet this demand.
Diabetes can cause many complications.
Acute complications (hypoglycemia, ketoacidosis or nonketotic hyperosmolar coma) may occur if the disease is not adequately controlled.
Serious long-term complications include cardiovascular disease (doubled risk), chronic renal failure, retinal damage (which can lead to blindness), nerve damage (of several kinds), and microvascular damage, which may cause impotence and poor healing.
Poor healing of wounds, particularly of the feet, can lead to gangrene, which may require amputation.

Animal Model and Probiotic Treatment

[0220]A cohort of fifty C57Bl / 6 10-wk-old male mice were fed a Normal Chow (NC) (A03, SAFE, Augy, France), or a high-fat diet (HFD) (comprising 72% fat (corn oil and lard), 28% protein and Diabetes 2008, 57, 1470-81; Knauf et al. Endocrinology 2008, 149, 4768-77; Cani et al., Diabetologia 2007, 50, 2374-83; Cani et al; Diabetes 2007, 56, 1761-1772 and Turini et al. Swiss Med Wkly 2007, 137, 700-4).

[0221]The mice underwent an intraperitoneal glucose tolerance test. The area under curve was calculated and the mice dispatched homogeneously according to the different experimental groups or ten mice per group (10 mice per group). The mice were fed four more weeks with a normal chow (n=10) or a HFD (n=40). The HFD mice were treated daily for 4 weeks as follows with, 1. Vehicle treated, 2. Bifidobacterium animalis subsp. lactis strain 420 (B420) (109 / bacteria per mouse), 3. Lactobacillus acidophilus NCFM (NCFM) (109 / bacteria per mous...

Materials and Methods

[0245]A cohort of C57Bl / 6 10-wk-old male mice were a high-fat diet (HFD) (comprising 72% fat (corn oil and lard), 28% protein and 9 bacteria per mouse), polydextrose (FDX) (0.2 g / day), the antidiabetic drug metformin (MET) (2 mg / mL drinking water), and various combinations of these. Control mice were treated with saline. Mice were housed in a controlled environment (inverted 12-h daylight cycle, light off at 10:00 a.m.). Blood glucose, insulin concentration and HOMA-IR were measured from plasma in fasted state.

Results

[0246]Treatment either with B420 alone or the combination of B420 and polydextrose reduced fasting plasma glucose as compared to control. Metformin alone did not have effect on fasting blood glucose but a combination with metformin and polydextrose was effective (FIG. 19).

[0247]Treatment with B420 reduced fasting plasma insulin. Addition of polydextrose further improved the effect, suggesting a synergistic effect of the combination. Metformin reduce...

Abstract

This invention relates to new uses of Bifidobacteria (particularly, although not exclusively, probiotic Bifidobacteria), and to food products, feed products, dietary supplements and pharmaceutical formulations containing them. The bacteria are suitable for the treatment of diabetes (particularly Type 2 diabetes), obesity and related conditions, metabolic syndrome, insulin resistance, and impaired glucose metabolism and consequences thereof, lowering tissue inflammation, treating hepatitis, myositis and cardiovascular conditions.

Description

FIELD OF THE INVENTION[0001]This invention relates to new uses of Bifidobacteria (particularly, although not exclusively, probiotic Bifidobacteria), and to food products, feed products, dietary supplements and pharmaceutical formulations containing them.DESCRIPTION OF THE PRIOR ART[0002]Diabetes mellitus, often referred to simply as diabetes, is a condition characterized by disordered metabolism and abnormally high blood sugar (hyperglycaemia) resulting from insufficient levels and / or action of the hormone insulin. The characteristic symptoms are excessive urine production (polyuria) due to high blood glucose levels, excessive thirst and increased fluid intake (polydipsia) attempting to compensate for increased urination, blurred vision due to high blood glucose effects on the eye's optics, unexplained weight loss, and lethargy. These symptoms are likely to be less apparent if the blood sugar is only mildly elevated.[0003]The World Health Organisation recognises three main forms of ...
