Dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) age-related withdrawal is very likely to be involved in the aging process and the onset of age-related diseases, giving rise to the question of whether preventing or compensating the decline of these steroids may have endocrine and clinical benefits. The aim of the present trial was to evaluate the endocrine, neuroendocrine and clinical consequences of a long-term (1 year), low-dose (25?mg/day) replacement therapy in a group of aging men who presented the clinical characteristics of partial androgen deficiency (PADAM). Circulating DHEA, DHEAS, androstenedione, total testosterone and free testosterone, dihydrotestosterone (DHT), progesterone, 17-hydroxyprogesterone, allopregnanolone, estrone, estradiol, sex hormone binding globulin (SHBG), cortisol, follicle stimulating hormone (FSH), luteinizing hormone (LH), growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels were evaluated monthly to assess the endocrine effects of the therapy, while β-endorphin values were used as a marker of the neuroendocrine effects. A Kupperman questionnaire was performed to evaluate the subjective symptoms before and after treatment.The results showed a great modification of the endocrine profile; with the exception of cortisol levels, which remained unchanged, DHEA, DHEAS, androstenedione, total and free testosterone, DHT, progesterone, 17-hydroxyprogesterone, estrone, estradiol, GH, IGF-1 and β-endorphin levels increased significantly with respect to baseline values, while FSH, LH and SHBG levels showed a significant decrease. The Kupperman score indicated a progressive improvement in mood, fatigue and joint pain.In conclusion, the present study demonstrates that 25?mg/day of DHEA is able to cause significant changes in the hormonal profile and clinical symptoms and can counteract the age-related decline of endocrine and neuroendocrine functions. Restoring DHEA levels to young adult values seems to benefit the age-related decline in physiological functions but, however promising, placebo-controlled trials are required to confirm these preliminary results. 相似文献

Introduction: After middle age, some men show androgen-deficiency symptoms leading to so-called PADAM (partial androgen deficiency in aging males). We tested the oral form of testosterone, testosterone undecanoate (Andriol®, NV Organon, The Netherlands), in men with PADAM and evaluated its efficacy and safety in Korean male patients. Methods: We included those patients with the clinical symptoms of PADAM who had decreased levels of serum total testosterone (< 2.8 ng/ml) or free testosterone (< 13 pg/ml). We excluded patients with biopsy-confirmed prostrate cancer, abnormal findings in digital rectal examination or prostate specific antigen testing (until prostrate cancer was ruled out), breast cancer, severe voiding symptoms and secondary hypogonadism. At the first visit, the International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF) and Korean Andropause Questionnaires were administered; complete blood count, the lipid profile, and levels of total and free testosterone, prolactin, luteinizing hormone, follicle stimulating hormone and prostate specific antigen were measured and a digital rectal examination was given. Patients were administered oral testosterone undecanoate 160 mg daily for 3 weeks. The dosage was then decreased to 80 mg daily and changes in symptoms were assessed at every visit. After 3 months, serum tests, including testosterone, were repeated. Results: We evaluated 28 patients who had received testosterone undecanoate for more than 3 months. The patients' mean age was 56.1 (48-68) years. The score of the Korean Andropause Questionnaire changed from 56.2 ± 21.7 at baseline to 52.9 ± 21.3 (p = 0.03) after 3 weeks, to 49.3 ± 19.3 (p = 0.03) after 8 weeks, and to 46.5 ± 25.6 (p = 0.028) after 12 weeks. With respect to sexual function, mean IIEF scores were 37.2 ± 19.6 at baseline and 38.7 ± 19.2 and 40.2 ± 22.0 (p = 0.033) after 3 and 12 weeks, respectively. Serum total testosterone increased from 2.13 ± 1.20 ng/ml at baseline to 6.04 ± 3.08 ng/ml (p = 0.005) after 12 weeks, and free testosterone was marginally significantly changed from 8.60 ± 2.25 pg/ml to 11.40 ± 3.81 pg/ml (p = 0.13). However, there were no significant changes in liver function tests, red blood cell count or lipid profiles. There were no significant adverse reactions that led to the cessation of the administration of oral testosterone. Conclusion: Oral administration of testosterone undecanoate can improve symptoms of PADAM in Koreans. It may, therefore, be an appropriate treatment option with few adverse effects for PADAM patients. 相似文献

The male aging process is accompanied by changes in the levels of several types of hormones. Falling levels of androgenic-anabolic steroids (total testosterone, free testosterone, biologically accessible testosterone, dehydroepiandrosterone) correspond to a group of symptoms referred to as PADAM syndrome (Partial Androgen Deficiency in the Aging Male). In the case of those carefully examined patients with symptoms of PADAM and proven hypogonadism, administering androgen supplements can alleviate some of the undesirable manifestations. In its literature, the University of St Louis repeatedly refers to its questionnaire as a verbal tool for the detection of possible hypogonadism.The aim of this study was to ascertain to what extent the aging process is evident in hormonal homeostasis detected in laboratory testing, and the extent to which this data is in accord with the evaluation of responses to questions in the University of St Louis questionnaire. Method: 216 men aged over 50 years were examined. Measurements were taken of: testosterone; the index of free testosterone; androstenedione; dihydrotestosterone; dehydroepiandrosterone and its sulfate; isomers 7α- and 7β-hydroxydehydroepiandrosterone; epitestosterone; luteinizing hormone (LH); follicle-stimulating hormone (FSH); prolactin; and sexual hormone-binding globulin (SHBG). Evaluations of the patients' responses to the University of St Louis questionnaire were compared with the results of the laboratory tests. Results: The study confirms that the most prominent phenomenon is that of an age-related decrease in the index of free testosterone, which is indicated in particular by an increase in the level of SHBG, and by a decrease in dehydroepiandrosterone and its derivatives. No significant correlation was found between levels of hormones and single items on the questionnaire, nor with the overall score arrived at by studying the patients' data. 相似文献
