Lack of dissociation of prolactin responses to thyrotropin releasing hormone and metoclopramide in chronic alcoholic men.

Abstract:

:Prolactin, growth hormone and thyroid stimulating hormone responses to thyrotropin releasing hormone (TRH) and metoclopramide were determined in 12 alcoholic men with biopsy proven liver disease and were compared to those of 8 age matched normal controls. All subjects were challenged with TRH (400 micrograms) and metoclopramide (10 mg) given as an intravenous bolus each on a separate day. Alcoholics had increased basal prolactin and growth hormone levels compared to controls. Alcoholics had a brisk and statistically significant (p less than 0.01) response for each of the 3 hormones studied in response to TRH. In contrast to the alcoholics, the controls did not demonstrate a growth hormone response to TRH. Moreover, the TSH response to TRH of the alcoholics was exaggerated (p less than 0.05) compared to that of the controls. In response to metoclopramide, alcoholics had a brisk prolactin response, failed to demonstrate a TSH response, and had a decline in growth hormone when compared to controls. These results for alcoholics with liver disease differ from those reported for individuals with renal failure while those for the controls are similar to previously reported normal responses. These data suggest that liver disease and renal disease must differ in terms of their patterns of hypothalamic-pituitary neuroregulation as documented by their differing pituitary hormone responses to TRH and metoclopramide.
