Human In Vitro Suppression as Screening Tool for the Recognition of an Early State of Immune Imbalance

Abstract:
The authors studied the Dexamethasone Suppression Test (DST) in chronic pain patients with and without major depression, using items from a modified version of the Hamilton Depression Scale, the Hamilton Anxiety Scale, and the Montgomery-Asberg Depression Rating Scale. The purpose of the study was to identify the factor or factors which discriminated DST suppressors from nonsuppressors. The data suggest that depression and its profile are efficient discriminators of suppressors and nonsuppressors. Anxiety-related items were not as good as discriminators. The items that identified nonsuppression were the items that are often seen in combination in endogenous depression.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
