“…Furthermore, the initial levels of these steroids positively correlated with a decline of somatic and psychosomatic symptoms as did the overall scores of the N-5 neurotic questionnaire (Figure 1a,b, Tables 2, 3 and 5). The ∆ 5 C19 steroids, and especially their 7α/β-7-oxo-and 16α-hydroxy-metabolites, are widely known as anti-glucocorticoid and immunoprotective substances [6,[28][29][30]. These results demonstrate that at least the activity of the ZR is augmented after intervention, and that its activity at the beginning of the treatment predicts the improvement in somatic and psychosomatic components of the N-5 neurotic questionnaire.…”

“…The most important finding from the viewpoint of patients' welfare is that immunoprotective (stimulate immune response but suppress autoimmunity) ∆ 5 C19 steroids such as DHEA, androstenediol, 7α-hydroxy-DHEA, 7-oxo-DHEA, and 5-androstene-3β,7α,17β-triol [6,[28][29][30][31][32] (see Table 6) showed a significant increase after intervention (Table 1). Furthermore, the initial levels of these steroids positively correlated with a decline of somatic and psychosomatic symptoms as did the overall scores of the N-5 neurotic questionnaire (Figure 1a,b, Tables 2, 3 and 5).…”

Spa treatment can effectively reestablish mood balance in patients with psychiatric disorders. In light of the adrenal gland’s role as a crossroad of psychosomatic medicine, this study evaluated changes in 88 circulating steroids and their relationships with a consolidation of somatic, psychosomatic and psychiatric components from a modified N-5 neurotic questionnaire in 46 postmenopausal 50+ women with anxiety-depressive complaints. The patients underwent a standardized one-month intervention therapy with physical activity and an optimized daily regimen in a spa in the Czech Republic. All participants were on medication with selective serotonin reuptake inhibitors. An increase of adrenal steroidogenesis after intervention indicated a reinstatement of the hypothalamic-pituitary-adrenal axis. The increases of many of these steroids were likely beneficial to patients, including immunoprotective adrenal androgens and their metabolites, neuroactive steroids that stimulate mental activity but protect from excitotoxicity, steroids that suppress pain perception and fear, steroids that consolidate insulin secretion, and steroids that improve xenobiotic clearance. The positive associations between the initial values of neurotic symptoms and their declines after the intervention, as well as between initial adrenal activity and the decline of neurotic symptoms, indicate that neurotic impairment may be alleviated by such therapy provided that the initial adrenal activity is not seriously disrupted.

“…β AET is found naturally in picomolar concentrations in human plasma [14], but is virtually absent in rodents without exogenous DHEA administration. β AET is not orally bioavailable, and plasma concentrations in humans cannot be appreciably augmented by DHEA supplementation due to DHEA's unfavorable absorption and metabolism characteristics [15]. HE3286 has anti-inflammatory activity in rodent disease models [16, 17].…”

“…HE3286 has anti-inflammatory activity in rodent disease models [16, 17]. Both β AET and HE3286 display many of the desirable anti-inflammatory activities reported for DHEA [18], suggesting that some aspects of DHEA's activity stem from polyhydroxylated metabolites that are readily formed in rodents [15]. HE3286 has no known intrinsic neuropharmacological activity or toxicity [13].…”

17α-Ethynyl-androst-5-ene-3β,7β,17β-triol (HE3286) is a synthetic androstenetriol in Phase II clinical development for the treatment of inflammatory diseases. HE3286 was evaluated for blood-brain barrier (BBB) permeability in mice, and efficacy in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) murine model of Parkinson's disease (PD). We found that HE3286 freely penetrated the BBB. HE3286 treatment significantly improved motor function compared to vehicle in the rotarod test (mean 58.2 sec versus 90.9 sec, P < 0.0001), and reduced inflammatory mediator gene expression in the brain (inducible nitric oxide synthase, 20%, P = 0.002; tumor necrosis factor α, 40%, P = 0.038, and interleukin-1β, 33%, P = 0.02) measured by reverse-transcriptase polymerase chain reaction. Brain tissue histopathology and immunohistochemistry showed that HE3286 treatment increased the numbers of tyrosine hydroxylase-positive cells by 17% compared to vehicle (P = 0.003), and decreased the numbers of damaged neurons by 38% relative to vehicle (P = 0.029). L-3,4-dihydroxyphenylalanine (L-DOPA) efficacy was not enhanced by concurrent administration of HE3286. HE3286 administration prior to MPTP did not enhance efficacy. Our data suggest a potential role for HE3286 in PD treatment, and provides incentive for further investigation.

“…A aplicação intravenosa de androstenodiol melhorou a sobrevivência de animal no modelo de sepse e o mesmo efeito foi observado com o uso de DHEA subcutâneo (Schmitz, Lendemans et al 2014). O metabólito androstenetriol (βAET) apresentou efeitos inibidores na produção de NO por células RAW264-7 após estimulação com LPS, além de redução do infiltrado celular em animais após estímulo com carragenina (Ahlem, Auci et al 2011). Além disso, Babickova et.…”
