CONCLUSION: We propose seeking for hypogonadism caused by endocrine conditions or ADT in men presenting with TdP. Caution is warranted when ADT is used in situations at risk of TdP. Testosterone may be useful to treat or prevent TdP. PMID: 31477476 [PubMed - as supplied by publisher]

Several studies highlight that testosterone deficiency is associated and predicts increased risk of developing metabolic disorders, and, that it is highly prevalent in obesity, metabolic syndrome and type-2 diabetes mellitus. Models of gonadotropin releasing hormone deficiency and androgen deprivation in patients with prostate cancer suggest that hypogonadotropic hypogonadism might contribute to onset or further worsen metabolic conditions by means of increased fat mass and insulin resistance. Nevertheless, in functional hypogonadism, such as late onset hypogonadism, the relationship between hypogonadotropic hypogonadism a...

CONCLUSIONS: In this systematic review and meta-analysis, we did not observe higher rate of BCR after TRT for nonmetastatic CaP patients after definitive local therapy. Based on these data, others and we have outlined a phase I/II trial assessing the safety and benefits of TRT in select men with secondary symptomatic hypogonadism who have no active disease after definitive local CaP therapy with curative intent.

CONCLUSION: The principal findings of this investigation were that low testosterone is correlated with elevated CgA levels, and these two parameters are associated with more aggressive grades and higher pathological stages of prostatic adenocarcinoma.

Abstract OBJECTIVE: Our aim was to evaluate the usefulness of serum testosterone to guide treatment decision for castration-resistant prostate cancer (CRPC). METHODS: We conducted a retrospective analysis of 115 patients with CRPC treated with either abiraterone (n = 43) or enzalutamide (n = 72). A serum testosterone level was measured at time of starting of abiraterone or enzalutamide. We determined whether serum testosterone influenced the outcomes of androgen receptor (AR)-targeted therapy. RESULTS: In the very-low testosterone group (

Purpose of review The aim of this study is to summarize recently published literature examining androgens and depression. Recent findings The impact of androgen levels, androgen replacement therapy and pharmacologic androgen deprivation on depression and depressive symptoms remain active areas of investigation. Recent publications support the finding that testosterone replacement therapy in men with low testosterone may improve depression, and that androgen deprivation therapy in men with prostate cancer may contribute to depression. Summary We review the recent literature on androgens and depression and highlight key developments.

Abstract Evidence has been accumulating that, in men, some of the biological actions traditionally attributed to testosterone acting via the androgen receptor may in fact be dependent on its aromatisation to estradiol (E2). In men, E2 circulates at concentrations exceeding those of postmenopausal women, and estrogen receptors are expressed in many male reproductive and somatic tissues. Human studies contributing evidence for the role of E2 in men comprise rare case reports of men lacking aromatase or a functional estrogen receptor alpha, short term experiments manipulating sex steroid milieu in healthy men, men wi...

Conclusion: These findings indicate that TBI differentially affects the levels of sex-steroid hormones in men and women patients. Plasma levels of testosterone could be a good candidate blood marker to predict recovery from unconsciousness after sTBI for male patients. Introduction Traumatic brain injury (TBI) is a major cause of death and disability worldwide and is increasing in incidence (1). Patients with acute severe TBI (sTBI) often develop severe disorders of consciousness, i.e., coma, minimally conscious state or vegetative state. Although many patients may regain consciousness during the 1-month post-TBI p...

This study is a post-hoc analysis of steroid hormones before and after administration of pharmacological doses of soy isoflavones in a large cohort of men and women from two independent studies. Isoflavones are reported to inhibit mineralo- and glucocorticoid hormone production as well as reproductive steroids in vivo and in vitro. We focused on cytochrome P450 17α-hydroxylase (CYP17A1) which catalyses the production of dehydroepiandrosterone (DHEA), in the androgen biosynthesis pathway to elucidate effects on sex steroids in vitro. Design and Setting: Effects of soy isoflavones on steroid levels in two studies comp...

AbstractObjectiveThere is a paucity of clinical data to support the hypothesis that external beam radiation therapy causes iatrogenic hypogonadism in prostate cancer patients.MethodsAll prostate cancer patients treated at a single institution with radiation therapy between 2002 and 2010 were retrospectively evaluated. Patients treated with brachytherapy alone received 0  Gy of external beam radiation therapy and served as the control group. Patients treated with combination external beam radiation therapy + brachytherapy, or external beam radiation therapy alone were categorized into groups who received 45–54&nb...
