System and method for diagnosis and treatment
This invention relates to a low cost rapid response diagnostic system to determine cortisol levels in patients selected as potential candidates for GCR (glucocorticoid receptor) antagonist therapy utilizing a GCR antagonist, such as ORG 34517. The rapid, sensitive, and inexpensive test can be used to determine patients who have non-normal cortisol production or disordered circadian rhythms as a method for selecting subjects for GCR antagonist therapy for whom it is likely to have beneficial and/or therapeutic effects, and can also be used to monitor changes in cortisol levels in response to treatment.
1. A method of treating post-traumatic stress disorder in a patient in need thereof comprising:
selecting a patient in need of treatment of post-traumatic stress disorder wherein said patient has elevated cortisol levels;
administering the GCR antagonist ORG 34517,
thereby treating post-traumatic stress disorder in the patient.
2. The method of claim 1 , wherein the patient's cortisol levels are measured in a test sample selected from the group consisting of saliva, blood, plasma, serum, urine, other bodily fluids, and combinations thereof.
3. The method of claim 2 , wherein the test sample is obtained from the patient at at least one predetermined time, wherein the predetermined time is selected from the group consisting of morning, noon, and evening.
4. The method of claim 2 , wherein the test sample is obtained from the patient over consecutive days.
5. The method of claim 1 , wherein the method further comprises determining the circadian cycle of the cortisol levels in the patient at a predetermined time, wherein the predetermined time is selected from the group consisting of hourly, every 4 hours, every 6 hours, every 8 hours, and every 12 hours.
6. The method of claim 5 , wherein the test sample is obtained from the patient over consecutive days.
7. The method of claim 1 , wherein said patient's cortisol level is compared to a predetermined reference range, wherein the predetermined reference range is a medically standard reference range.
8. The method of claim 1 , wherein said patient's cortisol level is compared to a predetermined reference range, wherein the predetermined reference range is the patient's previously measured level.
