Objective: To describe the evolution of neurobehavioral and cognitive symptoms in patients with primary hyperparathyroidism as measured by mini-mental state (MMS), Hamilton’s anxiety and depression scale (HADS) and Clock tests. Scores were also compared with biochemical data.Methods: The Swiss primary hyperparathyroidism (PHPT) Cohort Study is an ongoing, prospective, non-interventional national project collecting clinical, biochemical and outcome d...

We have previously reported the following metabolic abnormalities were common in 203 adult patients with CAH: obesity (41%), hypercholesterolemia (46%), insulin resistance (29%), osteopenia (40%) and osteoporosis (7%) (Arlt et al. JCEM 2010 95 5110–21). The CAH patients were taking different glucocorticoid therapies at various doses (n=196): hydrocortisone (n=25 M, 26 W), prednisolone (n=21M,67W), dexamethasone (n=15M,22W) or comb...

Obesity is associated with decreased hepatic reactivation of glucocorticoids (Gc) by 11β-hydroxysteroid dehydrogenase type 1 (11HSD) and increased metabolism of glucocorticoids by hepatic A-ring reductases, which may contribute to activation of the hypothalamic-pituitary-adrenal axis. Androgen action encourages central obesity and increased metabolic complications, possibly by altering Gc metabolism.This study investigates the role of gonadal androg...

Serum ALT concentrations give some insight into liver fat accumulation and relate to metabolic syndrome: values >29 IU/L double risk of type 2 diabetes independent of other risk predictors. Women with PCOS are at increased risk of diabetes and CVD whereas metformin treatment modulates the progress of metabolic syndrome. Consequently, we investigated the effects of protracted metformin treatment on circulating ALT in obese women with PCOS.Metformin tr...

Introduction: Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting about 5-10% of women. PCOS is characterized by hyperandrogenism, ovulatory disturbances, and polycystic ovaries. Many women with PCOS present with insulin resistance and central obesity and are at an increased risk for developing diabetes and cardiovascular disorders. Vitamin D deficiency is an important pathogenetic factor in the development of type II diabetes. The aim of the study was to...

Background: Patients with an insulinoma are at variable risk of severe hypoglycemia due to wide ranges of both tumoral insulin secretion and peripheral tissue sensitivity to chronic hyperinsulinaemia.Objectives: In this study we investigated the clinical, biological and tumoral characteristics of a large series of patients with immunohistochemically confirmed insulinoma and we assessed both insulin sensitivity and beta-cell function in fasting steady-sta...

Anti-Mullerian hormone (AMH) is produced by the ovarian granulosa cells in immature follicles from around week 36 of gestation to the menopause. Expression is highest in pre-antral and early antral follicles. AMH has a generally inhibitory effect on early follicle development and possibly on the responsiveness of growing follicles to FSH. Serum AMH is markedly elevated in women with PCOS and increased concentrations have also been reported in the healthy prepubertal daughters ...

BackgroundSerum testosterone remains the most important investigation in the diagnosis of androgen deficiency in men. Most of the circulating testosterone is bound to albumin and sex hormone binding globulin (SHBG), whereas free testosterone accounts for approximately 2% of total testosterone. Because direct measurement of free testosterone is impractical in routine practice, several equations have been used to provide clinically useful estimates of free...

Objectives: Testosterone deficiency has been associated with depressive symptoms, which may be improved by replacement therapy. Patients with chronic heart failure have a high prevalence of depression, which is associated with early mortality in these patients. Men with heart failure may also have low plasma levels of testosterone, which could contribute to depressed mood. In a clinical study investigating whether testosterone treatment benefits men with heart failure, patient...
