INTRODUCTION X-linked adrenal hypoplasia congenita (AHC) is a rare cause of adrenocortical insufficiency. Early postnatal diagnosis may prevent severe hypoglycemia, Addisonian crises and death. Low maternal estriol (E3) levels in the second trimester of pregnancy could indicate the possibility that the fetus suffers from a disorder that causes adrenal insufficiency. Suspicion is based on the fa...

BACKGROUND Epidemiological studies show a substantially reduced risk of breast cancer in adult daughters of preeclamptic pregnancies, and modest risk reductions have been demonstrated for mothers also. Alterations in pregnancy hormone concentrations, particularly lower in utero exposure to oestrogen, are hypothesized to mediate this association. METHODS Pregnancy hormone concentrations were m...

BACKGROUND Dehydroepiandrosterone (DHEA) and its sulfated ester DHEA-sulfate (DHEA-S), (together DHEA[S]), are the most abundant adrenal steroids in humans and are found in blood and the brain, where they function as neurosteroids with direct receptor affinities. Preclinical studies suggest that DHEA(S) has antidepressant/neuroprotective properties, and exogenously administered DHEA has shown a...

UNLABELLED In depression an increase, decrease, or a relative deficiency of dehydroepiandrosterone (DHEA) and the beneficial effects of its administration were observed. The correlation of low serum DHEA level and increased cardiac risk was confirmed in healthy subjects only in men (not in women). Taking into consideration the increased risk of heart disease in depression, it is interesting to ...

The hydroxylation of dehydroepiandrosterone (DHEA) to 7? -hydroxy-5-androstene-17-one (7?-OH-DHEA) and 7?-hydroxy-5-androstene-17-one (7?-OH-DHEA) by Gibberella sp. CICC 2498 Absidia coerulea 41050 was investigated. media ingredients were optimized. Single factors such as the DHEA concentration, culture time, medium volume, inoculum rate individually investigated generate optimum biotransformat...

OBJECTIVE In 2002 we proposed a new hypothesis of the etiology and pathogenesis of hypercholesterolemia. There is paucity of information in the literature regarding the association of steroidopenia and hypercholesterolemia. Our goal is to determine if the treatment of steroidopenia with hormonorestorative therapy (HT) to youthful levels will normalize total cholesterol (TC) levels. MATERIAL A...

Serum androgens as well as their precursors and metabolites decrease from the age of 30-40 yr in women, thus suggesting that a more physiological hormone replacement therapy at menopause should contain an androgenic compound. It is important to consider, however, that most of the androgens in women, especially after menopause, are synthesized in peripheral intracrine tissues from the inactive p...

Recently, we reported that several endogenous steroids affect CYP3A4-mediated drug metabolism, using human adult liver microsomes as an enzyme source. Especially, carbamazepine (CBZ) 10,11-epoxidation is activated by androstenedione (AND). In the present studies, we investigated the effects of endogenous steroids on the activity of CBZ 10,11-epoxidation by expressed CYP3A4 and CYP3A7. When expr...
