Table 1 provides details of demographic, historical, Tension Scores in Patient 4 before and during Low and High clinical, and laboratory data for the 12 patients.
Adrenal suppressive therapy was added to existing treatment regimens in all 12 cases. Treatment duration at the time of thisreport ranged between 3 to 16 months. Ketoconazole was considered the therapy of choice because low doses selectively inhibit C17,20-lyase, the enzyme directly responsible for the conversion of 17-hydroxypregnenolone to dehydroepiandros- terone (Couch et al 1987; Holland et al 1985; Sonino 1987).
Glucocorticoid treatment was used for suppression when normal- ization of DHEAS could not be achieved with ketoconazole (patients 1, 7, and 12). Table 1 presents the specific regimens and Anxiety was rated by the Tension score of the Profile of Mood States (POMS) (McNair et al 1992) questionnaire. All 12 patients completed pre- and post-treatment POMS questionnaires. All attempts were made to keep constant the doses of any concom- itant psychoactive medications during the period of treatmentwith adrenal suppressive medication.
