Previous studies have shown exaggerated ACTH and cortisol responses to ghrelin. Seven patients who were cured by transsphenoidal operation from CD were included in the study and tested with ghrelin (1 mcg/kg i.v.) before and six months after the operation. Their results were compared with eight healthy control subjects. Results are presented as mean±S.D. Mann–Whitney and Wilcoxon signed rank test were used for statistical analysis.<p class="abstext...

KLF11 is a pancreas enriched member of the Sp1/KLF transcription factor family which plays an important role in mammalian gene regulation. Previously we demonstrated that human (h)KLF11) inhibits human insulin promoter (hInsP) activity in rodent beta-cell lines via an unknown mechanism. Here we present results from ongoing experiments in which we test the hypothesis that KLF11 interferes with the major hInsP transactivator PDX1. We performed transient cotransfections of INS-1E...

Obesity protects from osteoporosis. Bone remodeling and energy metabolism could be regulated by the adipocyte-derived hormone, leptin acting on osteoblasts though hypothalamic pathways. Hypothalamic lesions cause obesity. Since most of these patients are also hypopituitary with low IGF1 which could affect bone metabolism the aim of our study was to investigate whether obesity would protect them from osteoporosis.Three groups of patients were studied: (1)...

Anorexia nervosa (AN) is associated with bone loss due to weight loss, decreased caloric intake, amenorrhoea and behavioral changes. The most important predictor of the occurrence of bone loss is body weight (BMI <16.5 kg/m2). Previous studies suggested that many factors including effects of chronic undernutrition in AN patients is associated with a reduction of bone formation (osteocalcin-OC) uncoupled with increased resorption markers (crosslaps-CTx). The aim ...

COGHD may be of genetic origin associated with deficiency of other pituitary hormones. Non treatment with GH in these cases can cause metabolic and other disturbances. The aim of this research was examining consequences of non treated COGDH in three sisters with familial hypopituitarism. Three sisters 60-, 59- and 54-year-old with familial hypopituitarism (GH,TSH, gonadotropin and prolactin deficiency) which was diagnosed 46 years before were examined. Substitution therapy per...

Goal: The aim of this study was to find different characteristics between GDM women aged under (GDM A n=23) and above 28 years (GDM B n=107), followed in our department in 2005.Material and methods: We performed ANOVA comparisons and computed Pearson correlations/linear regressions between womens’ age and BMI, O’ Sullivan test, OGTT 0 h, 1 h, 2 h and 3 h, new born weight and the need of insulin.Results: BMI ...

Within the exocrine pancreas, p8 expression is induced by pancreatitis and protects exocrine tissue from inflammatory damage via inhibition of NFκB. In previous work, we investigated the role of p8 within the endocrine pancreas and characterised p8 as a glucose-dependent mediator of beta cell proliferation. Here we investigate the hypothesis that p8 protects beta cells from cell damage by the diabetogenic drug STZ. We investigated native and transiently transfected INS-1E...

Introduction: Multiple endocrine neoplasia type 2 (MEN2) and medullary thyroid carcinoma (MTC) are autosomal-dominant inherited diseases caused by germline mutations within the RET protooncogene. Until now, genetic testing for mutations of exon 10, 11, 13, 14, 15 and 16 was recommended for these patients (familial and sporadic cases) to identify disease-causing mutations. Because of a strong genotype–phenotype correlation in these diseases, early genetic testing of...

Somatuline Autogel® 120 mg (SATG, Ipsen, Sweeden) is a high dose sustained release aqueous gel formulation, supplied in a prefiled syringe and given by deep subcutaneous injection. The aim of this cross-sectional hospital based study, approved by the local ethical committee, was to investigate efficacy and tolerability of SATG given every 4 weeks in patients with active acromegaly.Twenty patients (9f, 11m) aged 42.9±17.8 (range 17&#1...

Patients with hypopitutarism have higher cardiovascular morbidity and mortality rates than general population, as manifested by elevated fasting lipids and insulin resistance. The aim of our study was to evaluate the lipid levels and insulin responses during oral glucose tolerance test (OGTT) in adult onset growth hormone deficiency (AO-GHD), without growth hormone replacement during a follow-up period of seven years. Ten hypopituitary patients with operated non-functioning pi...
