Abstract
The invention deals with the use of cysteine, a cysteine precursor substance or a cysteine derivative or a cysteine-containing substance to increase the oxygen supply to the tissue by increasing the ventilatory activity and/or by increasing the production of the blood-forming hormone erythropoietin (EPO), especially for the treatment of aging-related or disease-related conditions associated with a decreased oxygen supply to the tissue, especially in elderly subjects, in the treatment of malignant diseases and in cardiorespiratory diseases.
Claims14
A method of treatment comprising:
- selecting a subject having a cardiorespiratory disease and having decreased ventilatory activity, decreased tissue oxygen supply, or plasma erythropoietin deficit;
- shifting the subject's plasma thiol/disulfide redox status to a degree sufficient to increase the ventilatory activity and plasma erythropoietin concentration so as to increase the subject's ventilatory activity, tissue oxygen supply, or plasma erythropoietin concentration.
A method of treatment comprising:
- selecting a subject with a cardiorespiratory disease having an unfavorable plasma thiol/disulfide redox potential;
- administering cysteine to the subject at a dose between 0.1 g and 20 g daily, wherein administering is selected from the group consisting of oral, intravenous, and intraperitoneal administration, so as to shift the subject's plasma thiol/disulfide status to thereby simultaneously increase the ventilatory activity and the plasma erythropoietin concentration and increase oxygen supply to the tissue of the subject.
