sodium-ethylxanthate and Hypopituitarism

Thirty-eight women, aged 25-65 yr, with androgen deficiency due to hypopituitarism were treated with oral dehydroepiandrosterone (DHEA; 30 mg/d if <45 yr of age and 20 mg if > or =45 yr of age) for 6 months in a randomized, placebo-controlled, double blind study, followed by a 6-month open treatment period. The administration of DHEA raised the serum levels of DHEAS to normal age-related reference ranges and increased androstenedione and T to subnormal levels. Androgen effects on skin and/or pubic and/or axillary hair were observed in 84% (32 of 38) of the women after all received 6 months of DHEA treatment. No such effects were observed after the placebo treatment. These effects after 6 months were correlated with the serum levels of DHEAS (r = 0.37; P = 0.03), androstenedione (r = 0.42; P = 0.01), and T (r = 0.37; P = 0.03). The percentages of partners who reported improved alertness, stamina, and initiative by their spouses were 70%, 64%, and 55%, respectively, in the DHEA group and 11%, 6%, and 11%, respectively, in the placebo group (P < 0.05). According to the partners, sexual relations tended to improve compared with placebo (P = 0.06). After 6 months of treatment, increased sexual interest or activity was reported by 50% of the women taking 30 mg DHEA, by none taking 20 mg DHEA, and by two women taking placebo (P = NS). Compared with levels after placebo administration, high density lipoprotein cholesterol and apolipoprotein A-1 levels decreased after DHEA. Serum concentrations of IGF-I, serum markers of bone metabolism, and bone density did not change. In conclusion, oral administration of a low dose of DHEA to adult hypopituitary women induced androgen effects on skin and axillary and pubic hair as well as changes in behavior, with only minor effects on metabolism.

Increased cardiovascular mortality and carotid atherosclerosis have been observed in hypopituitary patients with untreated GH deficiency (GHD), but results are contradictory and relations to cardiovascular risk factors are not clear. The aim of this study was to investigate intima-media thickness (IMT) in relation to cardiovascular risk factors in adults with GHD.. Cross-sectional observational study of 21 men and 13 women with GHD, but without cardiovascular disease, compared to two healthy control groups matched for age, sex and smoking habits. One control group was matched for body mass index (BMI) and the other group was nonobese.. IMT of the carotid and femoral arteries, blood pressure, blood samples and anthropometric data.. Patients had 12% thicker composite carotid IMT [(IMT of common carotid artery + IMT of bulb)/2] compared to nonobese controls (P = 0.022), but IMT was not different compared to BMI-matched controls. Femoral IMT did not differ between patients and controls. Patients had higher waist : hip ratio (WHR), heart rate, serum triglycerides and fasting insulin concentrations in combination with lower high-density lipoprotein (HDL) cholesterol and smaller low-density lipoprotein (LDL) peak particle size compared to both nonobese and to BMI-matched controls. This cardiovascular risk pattern was more pronounced in female patients than in male patients compared to their gender controls. Carotid IMT was related to age, serum cholesterol, LDL cholesterol and smoking in the patient group. Only age was independently related to carotid IMT in multivariate analysis.. These results indicate that high BMI in GH-deficient patients contribute to their increased intima-media thickness. However, several cardiovascular risk factors are present in this patient group independent of their increased BMI, especially in women.
