Abstract: The present invention relates to the new use of alpha-ketoglutarate, amides, and salts and mixtures thereof for the manufacture of a pharmaceutical preparation or a food or feed supplement for the in vivo therapeutic improvement of blood vessel elasticity, in particular arterial elasticity in a subject in need thereof. Improving the blood vessel elasticity may be used in the for the treatment and/or prophylaxis of hypertension, pulmonary arterial hypertension, cardiovascular disease, retinal vascular disease, heart failure, atherosclerosis, ventricular hypertrophy, stroke, arterial aneurysm, kidney failure, nephrosclerosis and diseases related to hypertension.
Abstract: The present invention relates to a method for diagnosing higher susceptibility for diseases and conditions associated with low levels of AKG in a human or animal comprising the following steps: a) obtaining a biological sample from said human or animal; b) measuring the alpha-ketoglutaric acid (AKG) level in the biological sample; and c) comparing said measured AKG level with normal average AKG levels, wherein a level of AKG in said sample lower than an average level is indicative of a higher susceptibility for various diseases. Further the invention relates to a use of a substance comprising at least one member selected from the group consisting of AKG and derivates, metabolites, analogues or salts thereof for the manufacture of a pharmaceutical preparation or a food or feed supplement for the treatment or prophylaxis of diseases and conditions associated with low levels of AKG in a human or animal with low levels of AKG compared with normal average AKG levels.
Abstract: Use of a substance for treating medical joint conditions, e.g. arthrosis, rheumatoid arthritis and cartilage impairment. The use includes the use of alpha-ketoglutaric acid, glutamine or glutamic acid, as well as salts, amides, di- or tripeptides of the mentioned substances.
