Growth hormone replacement in adults: Real-world data from two large studies in US and Europe.

Objective: This report describes the effectiveness and safety of growth hormone replacement in 3180 adult patients with growth hormone deficiency followed-up for 0.0-12.2 years in two completed, complementary, non-interventional, multicentre studies, NordiNet® International Outcome Study (IOS) (NCT00960128) and the American Norditropin® Studies: Web-Enabled Research (ANSWER) Program (NCT01009905).

Relationship of High Circulating Cystatin C to Biochemical Markers of Bone Turnover and Bone Mineral Density in Elderly Males with a Chronic Heart Failure.

Background: The aim of the study was to investigate the association of Cystatin C (CysC) to biochemical markers of bone turnover and bone mass, and to evaluate its prognostic significance in elderly males with chronic heart failure (CHF).

Methods: A prospective cohort study was executed on sixtyeight males (mean age 68±7 years) with mild to moderate CHF, together with 19 of corresponding age- and body mass index-matched healthy individuals who underwent cardio vascular, bone mineral density (BMD), and body com position assessment. Biochemical assessment of all subjects included NT-pro-BNP, parathyroid hormone (PTH), 25-hydroxy vitamin D (25(OH)D), CysC, and biochemical markers of bone turnover including osteocalcin (OC), alkaline phosphatase (ALP), β-CrossLaps (β-CTx), osteoprotegerin (OPG), and receptor activator of nuclear factor κB ligand (RANKL).

The impact of thyroid autoimmunity (TPOAb) on bone density and fracture risk in postmenopausal women.

Objective: Skeletal development, linear growth, cartilage biology and bone turnover are highly dependent on the activity of thyroid hormones. Thyroid dysfunction affects the skeleton, and autoimmune thyroid disease, manifesting as a chronic inflammatory condition, may be an important contributing factor to impaired bone quality in these patients.

Materials And Methods: Measurement of TSH, FT4, TPOAb and bone mineral density and FRAX score calculations were performed in 189 postmenopausal women (110 euthyroid women and 79 women diagnosed with subclinical hypothyroidism) divided into subgroups according to the presence of TPOAb.

Bridging the gap: metabolic and endocrine care of patients during transition.

Objective: Seamless transition of endocrine patients from the paediatric to adult setting is still suboptimal, especially in patients with complex disorders, i.e., small for gestational age, Turner or Prader-Willi syndromes; Childhood Cancer Survivors, and those with childhood-onset growth hormone deficiency.

Relationship between RANKL and neuroendocrine activation in elderly males with heart failure.

The main cytokines regulating bone remodeling are the receptor activator of nuclear factor-κB ligand (RANKL) and its decoy receptor, osteoprotegerin (OPG). Recent data have linked RANKL and OPG to cardiovascular disease as well. NT-pro-BNP and adiponectin are well-established biomarkers of heart failure reflecting neuroendocrine activation in this multi-complex disorder.

Relationship of reduced cerebral blood flow and heart failure severity in elderly males.

Introduction: Brain detrimental effects are under-recognised complication of chronic heart failure (CHF). One of the major causes may be cerebral hypoperfusion. This study was designed to investigate the relationship between cerebral blood flow (CBF) and severity of CHF as well as to evaluate its determinants among different parameters of cardiac dysfunction.

Relationship between high circulating adiponectin with bone mineral density and bone metabolism in elderly males with chronic heart failure.

Background: The aim of the study was to investigate the associations of adiponectin and leptin to bone mass and bone specific surrogates in elderly males with chronic heart failure (CHF).

Methods And Results: Seventy-three males (mean age 68 +/- 7 years) with stable mild to moderate CHF and 20 healthy individuals age- and body mass index-matching underwent dual energy x-ray absorptiometry measurements (bone mineral density (BMD) at hip and lumbar spine, total bone mineral content, and body composition); echocardiography; 6-minute walk test; grip strength; and biochemical assessment including adiponectin, leptin, bone specific surrogates (osteocalcin, beta-CrossLaps, osteoprotegerin [OPG], receptor activator of nuclear factor kappaB ligand [RANKL]), parathyroid hormone, 25-hydroxy vitamin D, testosterone, sex hormone-binding globulin, and NT-pro-BNP. Serum adiponectin, osteocalcin, beta-CrossLaps, OPG, RANKL, and parathyroid hormone were significantly increased in CHF patients, whereas 25-hydroxy vitamin D was significantly lower compared to healthy controls.
