Abnormalities in corticotropin-releasing hormone (CRH) secretion, noradrenergic neurotransmission, and serotonergic activity in the central nervous system (CNS) have all been hypothesized to exist in alcoholic patients, as have abnormalities in hypothalamic-pituitary adrenal function. To test these hypotheses, we continuously sampled cerebrospinal fluid (CSF) from alcoholic patients after 38-124 days of abstinence and from normal volunteers via a flexible, indwelling lumbar subarachnoid catheter and measured CRH, norepinephrine (NE), 3-methoxy-4-hydroxyphenylglycol (MHPG), tryptophan, and 5-hydroxyindoleacetic acid (5-HIAA) concentrations at 10-min intervals, from 11:00 through 17:00 h. The spinal canal catheter was inserted at approximately 08:00 h. Serial plasma ACTH, cortisol, and NE concentrations were also measured. A mixed liquid meal was consumed at 13:00 h. CSF CRH concentrations were lower in alcoholic patients than in normal volunteers (26 ± 15 vs. 60 ± 30 pg/ml, respectively, p < 0.05 by ANOVA), as were CSF NE levels (0.33 ± 0.09 vs. 1.15 ± 0.51 pmol/ml, respectively, p < 0.01). Plasma NE and CSF MHPG levels were normal in the alcoholic patients. CSF tryptophan and 5-HIAA and plasma ACTH and cortisol concentrations did not differ between the groups. These studies extend our finding of reduced spinal canal CSF CRH concentrations in depressed patients to abstinent chronic alcoholics. The very low CSF NE levels observed in our alcoholic patients stand in contrast to the normal CSF NE concentrations we previously found in depressed patients, and to their own normal levels of plasma NE and CSF MHPG (which largely reflect peripheral NE metabolism). Whether the deficits in CSF NE and CRH concentrations are the cause or consequence of alcoholism or abstinence or are related to the positively reinforcing effect of alcohol in alcoholics remains to be determined.
