Adult GH deficiency (GHD) is associated with prediabetes and low levels of GH are found in obesity. We hypothesized that zinc-α2-glycoprotein (ZAG), a novel adipokine reduced in obesity, is regulated by GH. ZAG serum and adipose tissue expression were measured in three study populations: i) cachectic (BMI=19.3±0.5 kg/m2), lean/overweight (BMI=26.0±0.5 kg/m2) and obese (BMI=36.0±1.6 kg/m2) patients with chronic obstructive pu...

THE SENSITIVITY OF 123I-MIBG IN THE DETECTION OF HISTOLOGICALLY CONFIRMED CATECHOLAMINE-PRODUCING TUMOURS.M Ismail, R Foley, WM Drake, AB Grossman, PJ Jenkins, SL Chew, GMBesser, R Reznek, K Britton, JP MonsonDepartments of Endocrinology, Nuclear Medicine and Radiology, StBartholomew's Hospital (QMUL), London EC1A 7BERadionuclide imaging is widely used for the loc...

Background:Circulating levels of IGFBP-3 are inversely associated with the risk of developing colorectal cancers (CRC). In addition to modulating IGF bioavailability, IGFBP-3 also exerts independent pro-apoptotic effects. Furthermore, the mode of action of several apoptotic and antiproliferative agents, including vitamin D, has been shown to involve induction of IGFBP-3.Aims:To quantitate and compare IGFBP-3 ...

OPUS is a population-based prospective cohort study of post-menopausal women from five European cities. We investigated whether TSH, fT4 and fT3 are associated with fracture risk, bone mineral density (BMD) at hip and spine, bone formation (osteocalcin, procollagen type 1 N-terminal propeptide), bone resorption (N- and C-telopeptides of type 1 collagen, NTX, CTX), pulse rate, grip strength and balance. Vertebral fractures were determined at baseline and 6 years follow-up. Usin...

Vitamin D plays an important role in the adaptive and innate immunity besides its skeletal effects. Some autoimmune disease is associated with vitamin D deficiency highlighting its crucial involvement in the onset of autoimmune diseases. This study investigated the relationship between the vitamin D supply and the serum IL-6, IL-17A and antibody levels against thyroid peroxidase (TPO) and TSH receptor in autoimmune thyroid diseases. Serum IL-6, IL-17A and antibody levels again...

Objective: To assess the metabolic characteristics, body composition, Insulin resistance and energy expenditure in young South Indian males with low and normal birth weight.Methodology: A population based cohort of 43 low birth weight (<2.5 kg) and 41 normal birth weight (>2.5 kg) subjects born at term was taken from a rural part in the South Indian state of Tamilnadu. Young healthy males aged 18–22 years were recruited. Following informed c...

Background: Metabolic disturbances could contribute to poor outcome after acute myocardial infarction (AIM) in type 2 diabetic patients.Objective: We examined the acid base disturbances that could contribute to poor prognosis after MI among type 2 diabetics suffering AMI.Methods: Parameters of acid base status and blood lactate level were compared (using one and two – way ANOVA) in 160 age-matched individuals. Forty of them we...

GH deficiency (GHD) in adults shares several clinical features with syndromes of glucocorticoid excess. Many patients with GHD also receive glucocorticoid therapy. GH inhibits the generation of active glucocorticoid by 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), but the confounding effect of ACTH deficiency/ cortisol replacement therapy has not been evaluated.Aims: To assess corticosteroid exposure and metabolism and body composition in...

Introduction: Thyroid dysfunction has been described as a common clinical entity in HIV infected patients, commonly with negative autoimmune tests. The aim of this work was to determine the prevalence of thyroid abnormalities in a cohort of HIV-infected males in a stable clinical state, the effect of exposure to ART on thyroid function and to identify the risk factors.Materials and methods: This is a cross-sectional, observational study of 90 HIV infecte...

Introduction: The hypothalomo-pituitary response to the loss of ovarian function due to ageing is an increase in GnRH induced gonadothropic activity: FSH. It is thought that the pituitary gives maximum endogenous stimulation leading to FSH levels above the ovarian threshold to develop follicular growth and it is a matter of debate whether exogenous FSH (r-FSH) will or will not improve ovarian response. In intrauterine insemination (IUI) treatment r-FSH is used to induce multif...
