The invention discloses a method for measurement of peptidic degradation products of a proteolytic cascade in biological samples, especially blood samples, wherein the sample is incubated until a steady state equilibrium is reached for at least one peptidic degradation product involved in said proteolytic cascade and wherein said at least one peptidic degradation product in steady state equilibrium of the proteolytic cascade is quantified in the sample.

Method for measurement of peptidic degradation products of a proteolytic cascade in blood samples

Methods and kits for the diagnosis of primary hyperaldosteronism (PHA). In particular, the present invention relates to the use of a new diagnostic parameter that is composed of the ratio between the Ang II level, in particular the steady state equilibrium Ang II level, and the aldosterone level in a biological sample, such as e.g. plasma. The ratio of the two measured parameters is used to diagnose PHA in patients and has clear advantages over currently used diagnostic methods.

Method for diagnosis of primary hyperaldosteronism

The present invention relates to a pharmaceutical composition comprising a. at least one aspartyl aminopeptidase inhibitor and at least one angiotensin-converting-enzyme (ACE) inhibitor, or b. at least one aspartyl aminopeptidase inhibitor and at least one chymase inhibitor. In an embodiment, the pharmaceutical composition comprises at least one aspartyl aminopeptidase inhibitor and at least one angiotensin-converting-enzyme (ACE) inhibitor and at least one chymase inhibitor. Furthermore, the invention relates to a pharmaceutical composition possessing inhibitory activity against a. aspartyl aminopeptidase and angiotensin-converting-enzyme (ACE), or b. against aspartyl aminopeptidase and chymase. In a third aspect, the invention relates to a kit of parts comprising a. a pharmaceutical composition comprising an aspartyl aminopeptidase inhibitor and a pharmaceutical composition comprising an angiotensin-converting-enzyme (ACE) inhibitor, or b. a pharmaceutical composition comprising an aspartyl aminopeptidase inhibitor and a pharmaceutical composition comprising a chymase inhibitor, or c. a pharmaceutical composition comprising an aspartyl aminopeptidase inhibitor and a pharmaceutical composition comprising an angiotensin-converting-enzyme (ACE) inhibitor and a pharmaceutical composition comprising a chymase inhibitor. The invention also relates to a method for decreasing the blood pressure in a subject by administering a therapeutically effective amount of a pharmaceutical composition according to the invention to the subject. In another aspect, the invention relates to a method for treating a disease related to the RAS in a subject by administering a therapeutically effective amount of a pharmaceutical composition according to the invention to the subject.

The ratio of the two measured parameters is used to diagnose PHA in patients and has clear advantages over currently used diagnostic methods.

The invention discloses a method for measurement of peptidic degradation products of a proteolytic cascade (for example, the renin-angiotensin system (RAS) and the bradykinin system) in biological samples, especially blood samples, wherein the sample is incubated until a steady state equilibrium is reached for at least one peptidic degradation product involved in said proteolytic cascade and wherein said at least one peptidic degradation product in steady state equilibrium of the proteolytic cascade is quantified in the sample.
