PURPOSE: Women with hypopituitarism have increased morbidity and mortality, and hypogonadism has been suggested to be a contributing mechanism. The purpose of this study was to investigate the prevalence of central hypogonadism and hypoandrogenism in women with hypopituitarism at a single Swedish center. METHODS: All consecutive women (n = 184) who commenced growth hormone (GH) replacement therapy at Sahlgrenska University Hospital in Gothenburg between 1995 and 2015 were included...

The acute metabolic actions of purified human GH was first documented in adult hypopituitary patients more than 50 years ago, and placebo controlled long term GH trials in GH-deficient adults (GHDA) surfaced in 1989 with the availability of biosynthetic human GH. Untreated GHDA is associated with excess morbidity and mortality from cardiovascular disease and the phenotype includes fatigue, reduced aerobic exercise capacity, abdominal obesity, reduced lean body mass, osteopenia, and elevated levels of circulating cardiovascular biomarkers...

OBJECTIVE: Alterations in the thyroid axis are frequently observed following growth hormone (GH) replacement, but uncertainty exists regarding their clinical significance. We aimed to compare fluctuations in circulating thyroid hormone levels, induced by GH, to changes in sensitive biological markers of thyroid hormone action. METHODS: This was a prospective observational clinical study. Twenty hypopituitary men were studied before and after GH replacement. Serum thyroid-stimulating hormone (TSH), thyroid hormones, and insulin-like growth factor 1 were measured...

PURPOSE: To examine differences in effects according to growth hormone (GH) treatment duration in adult GH-deficient patients. METHODS: In the Italian cohort of the observational Hypopituitary Control and Complications Study, GH-treated adults with GH deficiency (GHD) were grouped by duration of treatment; ≤ 2 years (n = 451), > 2 to ≤ 6 years (n = 387) and > 6 years (n = 395). Between-group differences in demographics, medical history, physical characteristics, insulin-like growth factor-I standard deviation score (IGF-I SDS) and lipid profile at baseline, last study visit and changes from baseline to last study visit were assessed overall, for adult- and childhood-onset GHD and by gender using ANOVA for continuous variables and Chi-squared test for categorical variables...

Hypopituitary dwarf mice demonstrate advantages of longevity, but little is known of their colon development and intestinal immunity. Herein we found that Ames dwarf mice have shorter colon and colonic crypts, but larger ratio of mesenteric lymph nodes (MLNs) over body weight than age-matched wild type (WT) mice. In the colonic lamina propria (cLP) of juvenile Ames mice, more inflammatory neutrophils (Ā: 0.15% vs. 0.03% in WT mice) and monocytes (Ā: 7.97% vs. 5.15%) infiltrated, and antigen presenting cells CD11c+ dendritic cells (Ā: 1...

Growth hormone deficiency (GHD) is one of the reasons of significant metabolic morbidities inchildren and adults. The aim of our study was to evaluate the impact of growth hormone (GH) replacement therapy on lipid profile and adipose tissue distribution in adults with GHD. Twenty hypopituitary adults, aged 40.75±2.2 years (mean ± SE, range 20.5-60), with adult onset GHD (aGHD) were enrolled in a randomized, double blind, placebo-controlled study. 10 patients received recombinant growth hormone injection once weekly for 12 months, and the rest 10 patients (as control group) received placebo...

PurposeCombined pituitary hormone deficiency (CPHD) is characterized by a malformed or underdeveloped pituitary gland resulting in an impaired pituitary hormone secretion. Several transcription factors have been described in its etiology, but defects in known genes account for only a small proportion of cases.MethodsTo identify novel genetic causes for congenital hypopituitarism, we performed exome-sequencing studies on 10 patients with CPHD and their unaffected parents. Two candidate genes were sequenced in further 200 patients...

Surgical treatment for epidermoid cysts of the chiasmatic region is a challenge because of the tendency to a massive spread of epidermoid masses through the cerebrospinal fluid pathways and a significant lesion deviation from the midline. PURPOSE: To analyze capabilities of the extended endoscopic endonasal transsphenoidal approach in surgery for epidermoid cysts. MATERIAL AND METHODS: The study included 6 patients with epidermoid cysts of the chiasmatic region who were operated on using the extended anterior endoscopic endonasal transsphenoidal approach at the Burdenko Neurosurgical Institute in the past 5 years...

AIMS: The nicotinic acid analogue acipimox is an antilipolytic agent, which acutely inhibits lipolysis and suppresses systemic levels of free fatty acids (FFA) and improves insulin sensitivity in obese patients. These effects of acipimox are transient due to a counter-regulatory increase in growth hormone levels that reverse the antilipolytic effect of acipimox. Hypopituitary patients constitute a viable model to study the growth hormone-independent effects of acipimox and the impact of isolated changes in FFA concentrations and insulin sensitivity on parasympathetic nervous activity...

PURPOSE: Central diabetes insipidus is characterised by arginine vasopressin deficiency. Oxytocin is structurally related to vasopressin and is synthesised in the same hypothalamic nuclei, thus we hypothesised that patients with acquired central diabetes insipidus and anterior hypopituitarism would display an oxytocin deficiency. Moreover, psychological research has demonstrated that oxytocin influences social and emotional behaviours, particularly empathic behaviour. We therefore further hypothesised that central diabetes insipidus patients would perform worse on empathy-related tasks, compared to age-matched and gender-matched clinical control (clinical control-isolated anterior hypopituitarism) and healthy control groups...

Ghrelin produced in the gut stimulates GH and ACTH secretion from the pituitary and also stimulates appetite and gastric emptying. We have shown that ghrelin also induces insulin resistance via GH-independent mechanisms, but it is unknown if this effect depends on ambient fatty acid (FFA) levels. We investigated the impact of ghrelin and pharmacological antilipolysis (acipimox) on insulin sensitivity and substrate metabolism in 8 adult hypopituitary patients on stable replacement with GH and hydrocortisone using a 2 × 2 factorial design: Ghrelin infusion, saline infusion, ghrelin plus short-term acipimox, and acipimox alone...

INTRODUCTION: Growth hormone deficiency is considered the most important factor determining skeletal fragility in hypopituitary patients. Osteoblasts and chondrocytes express growth hormone (GH) receptor. Two GH receptor isoforms (GHRi) have been identified: they differ for the presence/absence of a protein fragment encoded by exon 3 of GHR gene. Consequently, three genotypes were identified: carriers of both the full-length proteins (flfl-GHR), carriers of one full-length protein and one deleted protein (fld3-GHR) and carriers of both deleted proteins (d3d3-GHR)...
