Introduction: Resistance to thyroid hormone (RTH) is a rare disease, characterized by elevated thyroid hormone and not suppressed TSH concentrations. In 85% of cases it is related to TRβ gene mutations.Objectives: To evaluate biochemical and densitometric features of 14 patients with RTH (RTHG: 7 females (4 children) and seven males (2 children)) in comparison to 24 control subjects (CG, 14 females (8 children) and 10 males (4 children)).<p clas...

Osteoclast presents a central role in several inflammatory diseases that are associated to bone destruction. This condition results from increased osteoclastic bone resorption and/or decreased bone formation. Fluoride (F) is widely consumed in the drinking water due to its anticariogenic effect and has been shown to modulate in vivo bone metabolism in a strain-specific dependent manner. It enhances bone formation in 129P3/J mice but not in A/J mice. However, its effec...

Aim: Aim of our study was to investigate the serum adiponectin, leptin, and osteoprotegerin (OPG) levels and its expressions in the adipose tissue, and their relationships with bone metabolism and in patients with severe C chronic obstructive pulmonary disease (COPD).Materials and methods: Serum leptin, adiponectin, OPG, the receptor activator of nuclear factor-kB ligand (RANKL), and bone turnover markers (osteocalcin and type 1 collagen C-telopeptide (C...

Aim: To assess the relationships of serum osteoprotegerin (OPG), receptor-activator of nuclear factor-κB ligand (RANKL) and tumor necrosis factor-alpha (TNF-α) superfamily with bone composition in end-stage COPD.Methods: Body and bone composition, serum OPG, RANKL, TNF-α and its receptors (sTNFR I, sTNFR II), TNF-related apoptosis-inducing ligand (sTRAIL) levels were measured in 48 men end-stage COPD accepted for lung transplantation, and ...

Introduction: Paget’s bone disease (PBD) is the second most prevalent metabolic bone disease. Most patients present with pain or fracture but many remain asymptomatic. Evidence suggests a significant reduction both in its prevalence and clinical severity. Recent papers described differences in clinical course and therapeutic options in the last 10–15 years.Objective: To characterize PBD differences between patients having been diagnosed before ...

Objective: To determine associations between the adipokines tumor necrosis factor-α (TNF-α) and its receptors sTNFR I, II, leptin, adiponectin, resistin, ghrelin, pulmonary function testing, bone mineral density (BMD) and nutritive status in severe COPD.Materials and methods: We determined BMD, serum adipokine and ghrelin in 48 patients with severe COPD and and 52 age and sex matched controls.Bone density at lumbar spine ...

Introduction: Anorexia nervosa usually has its onset during adolescence, the critical time when peak bone mass is accrued. Inadequate nutrition abnormalities and endocrine changes during starvation have a negative effect on bone health. The aim of this work was to investigate the effects of hormonal and auxological parameters on markers of bone metabolism, bone mineral density in girls with anorexia.Patients a...

Introduction: FGF-21 is a protein that is produced by the liver and adipocytes. In patients with anorexia nervosa (AN), it could be involved in a complex adaptive response to starvation. In addition, this newly discovered protein could play pathogenic role in trabecular skeletal homeostasis. The aim of our work was to evaluate the concentrations of FGF-21 and bone metabolism in patients with AN.Methods: Thirty seven female patients (aged 14.76±3.99 ...
