[Dynamics of the corticotropin, cortisol and prolactin content of the blood plasma of women with Itsenko-Cushing disease administered luliberin].

The paper is concerned with the results of a study of the level of plasma ACTH, cortisol and prolactin before and after i. v. injection of LHRH to 20 patients with Itsenko-Cushing disease and to 5 healthy persons. In healthy persons LHRH injection caused no significant changes in the level of plasma ACTH, cortisol and prolactin. Patients with Itsenko-Cushing disease who had a high basal level of corticotropin on the 30th min after i.v. LHRH injection demonstrated a significant increase in the hormone level. A response to LHRH injection was absent in patients with a normal basal level of corticotropin and in healthy persons. A statistically significant increase in cortisol concentration was noted on the 60th min after LHRH injection in some of the patients responding to LHRH by a high ACTH level. LHRH injection was not accompanied by significant changes in the level of plasma prolactin in either of the subgroups.
