DHEA, DHEAS and prolactin correlate with glucose control parameters in women of fertile age with type-1 diabetes mellitus.

The aim of our work was to provide data from women of fertile age with type 1 diabetes mellitus about the endogenous androgens and on their relations to the parameters of diabetes control. Forty-two women were examined, they did not use contraceptives for at least three months prior to the examination. A multivariate regression analysis showed that the daily insulin dose, the fasting glycemia and the HbA1c values and patient's age correlated negatively with dehydroepiandrosterone sulfate, dehydroepiandrosterone and prolactin levels.

Comparison of a high-carbohydrate and high-protein breakfast effect on plasma ghrelin, obestatin, NPY and PYY levels in women with anorexia and bulimia nervosa.

Background: The present study investigated plasma levels of gut-brain axis peptides ghrelin, obestatin, NPY and PYY after consumption of a high-carbohydrate (HC) and high-protein (HP) breakfast in patients with anorexia nervosa, bulimia nervosa and in healthy controls. These peptides play an important role in regulation of energy homeostasis and their secretion is disturbed under condition of eating disorders. As various types of consumed macronutrients may induce different plasma hormone responses, so we examined these responses in women patients with eating disorders and compared them with those of healthy controls.

T2D risk haplotypes of the TCF7L2 gene in the Czech population sample: the association with free fatty acids composition.

The association of transcription factor 7-like 2 (TCF7L2) gene variants with the pathogenesis of T2D, gestational diabetes and polycystic ovary syndrome (PCOS) was examined. The study involved 1460 individuals: 347 T2D patients (D); 261 gestational diabetics (G); 147 offspring of T2D (O); 329 women with PCOS, and 376 controls (C). The SNPs: rs7901695; rs7903146; rs12255372 in the TCF7L2 gene were genotyped.

[Birth weight and genetic risk of type 2 diabetes in Czech population].

Introduction: Birth weight is associated with type 2 diabetes mellitus and other late-onset metabolic diseases. Reduced birth weight is associated with an increased risk of insulin resistance, type 2 diabetes, and atherosclerosis. Also high birth weight represents risk factor for development of type 2 diabetes later in life.

Evaluation of hepatic 11 beta-hydroxysteroid dehydrogenase activity by cortisone acetate test in young adults with diabetes mellitus type 1.

Cortisone acetate test was performed in twelve young adult patients with diabetes mellitus type 1, after dexamethasone administration to suppress endogenous cortisol production. Previous screening revealed that all of the subjects had peak cortisol responses in the range from subnormal to normal, as determined by a low-dose Synacthen test. The aim was to find out whether these patients would exhibit different conversion of cortisone to cortisol by 11beta-hydroxysteroid dehydrogenase.
