Compositions comprising ketone bodies and/or their metabolic precursors are provided that are suitable for administration to humans and animals and which have the properties of, inter alia, (i) increasing cardiac efficiency, particularly efficiency in use of glucose, (ii) for providing energy source, particularly in diabetes and insulin resistant states and (iii) treating disorders caused by damage to brain cells, particularly by retarding or preventing brain damage in memory associated brain areas such as found in Alzheimer's and similar conditions. These compositions may be taken as nutritional aids, for example for athletes, or for the treatment of medical conditions, particularly those associated with poor cardiac efficiency, insulin resistance and neuronal damage. The invention further provides methods of treatment and novel esters and polymers for inclusion in the compositions of the invention.
A method of treating a patient for a neuro-degenerative disorder selected from the group consisting of those involving inability to metabolise glucose inhibition of pyruvate dehydrogenase memory loss in aging, neurotoxic peptides or proteins, and genetic abnormality comprising administering to that patient a therapeutically effective amount of one or more of D-β-hydroxybutyric acid, acetoacetate, or a metabolic precursor or physiologically acceptable salt of D-β-3-hydroxybutyric acid or acetoacetate, such as to elevate the patient's blood level of ketone bodies, defined as the sum total of D-β-hydroxybutyric acid and acetoacetate, to a therapeutic level effective to treat the disorder
A method of treating a patient in order to treat a neuro-degenerative disorder selected from the group consisting of those involving inability to metabolise glucose, inhibition of pyruvate dehydrogenase, memory loss in aging, neurotoxic peptides or proteins, and genetic abnormality comprising administering to that patient a therapeutically effective amount of at least one of D-β-hydroxybutyric acid, acetoacetate, or a metabolic precursor or physiologically acceptable salt of D-β-hydroxybutyric acid or acetoacetate, such as to elevate the patient's blood level of ketone bodies, defined as the sum total of D-β-hydroxybutyric acid and acetoacetate, to a therapeutic level effective to treat the disorder
A method of treating a CNS cell, peripheral nerve cell, or otherwise insulin insensitive cell in need of therapy for a condition selected from the group consisting of one or more of neuro-degeneration in which the cell is subject to inhibition of pyruvate dehydrogenase, neurotoxic effects of pathogenic peptides, proteins and genetic abnormality, GABA preventable seizure, or insufficient ability to metabolise glucose, comprising administering to that cell one or more compounds selected from the group consisting of D-β-hydroxybutyric acid, acetoacetate, compounds which are oligomers of D-β-hydroxybutyric acid, acetoacetyl esters of D-β-hydroxybutyric acid and acetoacetyl esters of oligomers of D-β-hydroxybutyric acid, and physiologically acceptable salts thereof.
A method of treating a patient for a condition selected from the group consisting of epilepsy, diabetes or an insulin resistant state comprising administering to that patient a therapeutically effective amount of one or more compounds selected from the group consisting of D-β-hydroxybutyric acid, acetoacetate and metabolic precursors of D-β-hydroxybutyric acid or acetoacetate which comprise moieties selected from the group consisting of R-1,3-butandiol, acetoacetyl and D-β-hydroxybutyryl moieties and physiologically acceptable salts and esters thereof.
