preeclampsia is a major cause of morbidity and mortality during pregnancy. several independent investigators have demonstrated the association of androgens with hypertension. the main purpose of this study was to determine whether maternal levels of sex hormones, especially testosterone, are higher in patients with preeclampsia than in matched normotensive control subjects. serum levels of test...
OBJECTIVES This single-dose study compares three dehydroepiandrosterone delivery methods (oral crystalline steroid, micronized steroid, and vaginal administration) to ascertain whether physiologic levels of circulating dehydroepiandrosterone and dehydroepiandrosterone sulfate can be obtained while increases in testosterone are minimized. STUDY DESIGN Two randomized, double-blind, placebo-cont...
to evaluate the maternal serum dehydroepiandrosterone sulfate level as a factor associated with the outcome of labor induction. venous blood was collected from 45 women at the initiation of labor induction. pregnancies complicated by maternal corticosteriod use, anterpartum chorioamnionitis, or cesarean delivery for indications other than arrest disorders, were excluded from analysis. in 42 wom...
to evaluate the maternal serum dehydroepiandrosterone (dhea) sulfate levels as a factor influencing labor ‘efficiency’ at term and unsuccessful labor induction. this is a prospective study. in this study the mean (± standard error) maternal serum dhea sulfate levels of 90 singleton pregnant women in 3 groups with spontaneous labor, need for augmentation and need for induction were compared.preg...
دی هیدرواپی اندروسترون (dhea) و مشتق سولفاته آن (dhea-s)، مهمترین هورمون استروئیدی c19 می باشد که توسط قشر آدرنال ترشح می شود. چنین تصور می شود که می باید همبستگی معکوسی میان آتروژنز از طریق اثر ضد پرولیفراتیو آن موجود باشد؛ ولی در مورد این مطلب گزارشهای ضد و نقیضی وجود دارد. هدف این مطالعه، بررسی اثر dhea-s بر روی بیماری عروق کرونر قلبی است. در یک مطالعه تصادفی آینده نگر، 202 فرد با cad احتمال...
Several significant interrelations among variation in blood pressure, body fat, and adrenal androgen levels, as assessed by serum dehydroepiandrosterone sulfate concentrations, were found in black male and female adolescents, aged 12 to 16 years. In girls, high levels of dehydroepiandrosterone sulfate were associated with significantly higher levels of blood pressure (alpha = 0.05), even after ...
BACKGROUND This study aimed to evaluate some of the major risk factors of myocardial infarction including dehydroepiandrosterone sulfate in patients with premature myocardial infarction (age <50 years old) and myocardial infarction (age ≥50 years). METHODS This is a parallel case-control study on 50 premature myocardial infarction patients and 50 myocardial infarction patients. We also recrui...
Dehydroepiandrosterone and dehydroepiandrosterone sulfate are steroids which may be associated with the development of breast cancer. To examine the association between serum levels of dehydroepiandrosterone and dehydroepiandrosterone sulfate and the risk of developing premenopausal breast cancer, we measured hormone levels in 15 women who donated blood to a community-based serum bank in 1974 a...
