Introduction: Insulin neuritis is a rare form of presentation of diabetic neuropathy, usually associated with the sudden intensification of glucose control in individuals with long standing uncontrolled diabetes mellitus.Objectives: To report a case of insulin neuritis in a young male, few weeks after diagnosis and insulin therapy initiation.Clinical case: Male, 22 years old, previous history of excess weight until he was 19 years ...

Insulin resistance affects 50–70% of women with polycystic ovary syndrome (PCOS).The aim of our study was to estimate the prevalence of insulin resistance by different methods in a single cohort of 63 PCOS patients diagnosed by the Rotterdam criteria.Methods: Anthropometric measurement, examination and fasting blood tests were made on the 3–5th days of their periods. HOMA-IR (cut off >2.5) and QUICKI (cut off <0.3...

Introduction: Human recombinant growth hormone (hrGH) treatment in adult patients with GH deficiency (GHD) has an important interindividual variability and several factors can influence it. The aims of the study were: i)- to analyze the genotype of GHR regarding exon 3 deletion (d3-GHR) in a serie of adult patients with GHD; ii)- to assess the effect of d3-GHR on initial IGF1 levels; iii)- to evaluate if d3-GHR and/or initial IGF1 levels were associated with adverse effects an...

Introduction: Hypophysitis is an inflammatory disease of the pituitary that may mimic tumors. Primary hypophysitis has been classified as lymphocytic (LH), granulomatous (GH), and xanthomatous (XH). It has been recently proposed to be an IgG4-related autoimmune disease (serum IgG4 concentration: 135 mg/dl), proven by tissue IgG4 immunostaining.Case description: A 23-year-old men suffered from typical cluster type headache. Two years after the first sympt...

Some steroids modulate the permeability of ionotropic receptors on cell membranes and therefore may activate or inhibit neuronal activity depending on the steroid structure. These neuroactive steroids (NAS) exert neuroprotective effects like the neuronal remyelination.Multiple sclerosis (MS) is the most common cause of neurological disability in young adults. Therefore, the authors have followed the neuroprotective, GABAergic, glycinergic, glutamatergic ...

Variation in the human glucocorticoid receptor (GR) gene associates with relative glucocorticoid resistance, hypertension and increased cardiovascular disease risk. Mice heterozygous for a null GR mutation (GR+/−) are also glucocorticoid resistant with raised circulating glucocorticoid levels and elevated blood pressure in adulthood. We have characterised the cardiac phenotype of these mice throughout development and investigated their response to cardiovascul...

Background: Vitamin D is important to skeletal health and is standard care in conditions with low BMD. Thyrotoxicosis caused by Graves’ disease (GD) leads to increased bone turnover and reduced BMD. We aimed to test the hypothesis that vitamin D supplementation would improve bone recovery in GD.Methods: Using a double-blinded design, hyperthyroid patients with a first time diagnosis of GD were randomized to supplementation with vitamin D3 70 mg/day...

Objective: Acromegaly is caused by a growth hormone (GH)-secreting pituitary tumor and its signs are linked to increasedGH-dependent hepatic insulin-like growth factor I (IGF-I) synthesis. A eucaloric very low-carbohydrate ketogenic diet (euVLCK; < 50 g/day) induces ketosis and reduces portal insulin concentrations, which down-regulate hepatic GH receptors and reduce IGF-I synthesis. Somatostatin receptor ligands (SRLs) reduce GH secretion by the pituitary tumor,resul...

Background: In females transitioning to males (FtM) and in males transitioning to females (MtF), exogenous cross-sex steroids are prescribed to favour development of secondary characteristics of desired sex, while endogenous hormone production is inhibited.Aims and design: To study early impact of cross-sex steroids on body composition, metabolic profile and pro-inflammatory parameters in young transgender persons before and after 12 months of gender-aff...

IL17 proinflammatory cytokine through T cell activation has prominent bone-wasting effect. Our previous results highlighted the role of IL17 in postmenopausal osteoporosis. To demonstrate the HLA allele association with the increased IL17 levels in postmenopausal osteoporosis was the object of the study.HLA class I and II alleles were measured in 64 postmenopausal women (in four subgroups: with low IL17 (1, 3) and high (>3.04 pmol/l) IL17 levels (2, ...
