Hydrocortisone treatment in septic shock promotes shock reversal and reduces mortality. We hypothesised the doses that used (200–300 mg/2 h) would result in plasma cortisol levels sufficient to saturate the 11 beta-hydroxysteroid dehydrogenase 2 enzyme (11 beta-HSD 2) with cortisol inactivation overload. Consequently cortisol would access the mineralocorticoid receptor producing mineralocorticoid effects. Hypertensive metabolic alkalotic effects would tend to counteract t...

Apolipoprotein (Apo)-B is a strong predictor of coronary risk in the general population. Whether it contributes to coronary disease in patients with reduced kidney function is unclear. We examined the prevalence and relationship of Apo-B with physician-diagnosed myocardial infarction among 7,404 adults age >20 years with reduced glomerular filtration rate (GFR) in the U.S. population. GFR was estimated Modification of Diet in Renal Disease Study (MDRD) equation and calibra...

Familial Glucocorticoid Deficiency type 2 (patients with normal MC2R) is associated with mutations in the MRAP (Melanocortin Receptor Accessory Protein) gene. In order to investigate the function of this novel single transmembrane domain protein, CHO and SKN-SH cells were transfected with MRAP-FLAG and/or MC2R-GFP constructs and imaged using confocal microscopy. Although the MC2R-GFP failed to be expressed at the cell surface when transfected alone, it was found to be expresse...

The peptide hormone ACTH stimulates lipolysis and suppresses leptin production in adipocytes via the G-protein coupled seven transmembrane receptor, MC2-R. We have shown previously that PPARγ2 is the primary factor responsible for transactivation of the already identified murine MC2-R promoter in the differentiating 3T3-L1 adipocyte cell line. In this study we show that despite the activity of this promoter being transient during differentiation, MC2-R mRNA remains elevat...

The purpose: to study prevalence of classical forms of 21-hydroxylasae deficiency according to the results of neonatal screening on a congenital adrenal hyperplasia (CAH) in Tyumen, Russia.The analysis of neonatal screening on CAH results in Tyumen for the period of 2003–2004. For the period under research 20011 newborn have been tested on the 17-OHP level. Measurement of 17-hydroxyprogesterone in blood samples was done in the central laboratory by ...

Background: Thyrotoxicosis is a common disorder with a prevalence of 3% in females and 0.3% in males in iodine replete areas. The prevalence may be higher in areas of iodine deficiency. It is known to induce many cardiovascular effects. The most important complication of thyrotoxicosis is atrial fibrillation. We aimed to assess thyroid function in patients with atrial fibrillation and determine the frequency of thyrotoxicosis in this group.Methods: We st...

Introduction: The objective of this study is to detect whether the correction of hypomagnesaemia would help to relief the symptoms of hypocalcaemia that occurs after thyroidectomy. Methods: This prospective study comprised 35 patients who had thyroidectomy between September 2001 and June 2002. Thirteen patients had total thyroidectomy (TT), thirteen had total lobectomy on one side and subtotal lobectomy on the other side (TLSL) and nine patients had hemi...

Aim: To estimate further results of treatment and outcomes in patients with subacute thyroiditis observed in the period from 1993 to 2005 years.Materials and methods: 102 patients (84 women, 18 men) with confirmed De Quervain’s subacute thyroiditis (SAT) were investigated and the findings were analysed retrospectively (clinical features, ultrasonography, laboratory tests). Ultrasound device (Hewlett Packard Image Point HX) with 7.5 – 10 MHz. Se...

Introduction: Altered nutritional status is a problem in itself that can complicate a patient’s disease. In our hospital, the assessment of nutritional status at hospital admission is protocolized and performed by the Clinical Laboratory automatically, through the CONUT system, for three years ago. Our hospital provides assistance to a population of 120,000 patients, from rural areas and with a high average age. Hospital admissions for cognitive impairment are increasing ...

Background: Whether combination therapy of levothyroxine and liothyronine increases the risk of atrial fibrillation remains a topic of debate.Objectives: The objective of this study was to investigate the risk of atrial fibrillation in individuals with hypothyroidism treated with a combination of levothyroxine and liothyronine.Methods: We conducted a retrospective cohort study using individual-level linkage of Danish nationwide reg...
