title: Relationship between serum cortisol, liver function, and depression in detoxified alcoholics.
abstract: High levels of serum cortisol or abnormal dexamethasone suppression tests may be helpful in diagnosing major depressive disorder. However, a controversy exists as to whether abnormal liver function associated with alcohol abuse may negate the diagnostic value of the dexamethasone suppression test in alcoholics. We investigated the value of the dexamethasone suppression test in alcoholics by analyzing the liver function, cortisol levels, and psychiatric status of inpatients from an alcohol detoxification treatment center. The subjects met the DSM III criteria for alcohol dependence but took no chronic medication and had negative screening for substance abuse. They had routine blood screening to evaluate liver function, the afternoon cortisol test and dexamethasone suppression test to study glucocorticoid activity, and a structured evaluation to determine psychiatric diagnoses. The blood chemistry findings demonstrated a lack of significant liver synthetic dysfunction in this group, although 43% of the subjects had some elevation of their liver enzymes. We did not find differences in the liver function between patients with normal and abnormal cortisol levels. However, subjects with endogenous depression did have significantly elevated afternoon cortisol levels, and they tended to have more normal liver tests. These results indicate that modest liver dysfunction does not contaminate the validity of the plasma cortisol tests or the dexamethasone suppression test as diagnostic tools for assessing depression in this group of detoxified alcoholics. In addition, they demonstrate an association between depression and plasma cortisol levels and suggest a correlation between depression and better liver function in alcoholics who seek detoxification.
