Objective: The aim of this study was to assess the relationship between renal function (estimated glomerular filtration rate (eGFR) using Cockcroft–Gault (CG) equation and modification of diet in renal disease (MDRD), respectively), bone mineral density (BMD) and both arterial stiffness in Korean postmenopausal women.Materials and methods: From January 2008 until December 2010, among the person who got medical examinations including bone densitometr...

Objectives: To evaluate bone health and its possible correlations to body composition parameters in young patients with galactose metabolic disorders, aiming to suggest appropriate lifestyle interventions.Methods: We studied 22 patients, aged 5–16 years with galactose metabolic disorders, detected by neonatal screening. Fourteen suffered from classic galactosemia and eight from other galactose metabolic disorders (i.e. epimerase or galactokinase def...

Objectives: Obese adults commonly have vitamin D deficiency and secondary hyperparathyroidism prior to bariatric surgery. Whether similar metabolic abnormalities exist in morbidly obese adolescents is not known. This study investigated the prevalence of vitamin D deficiency and evaluated the relationship between vitamin D and parathyroid hormone (PTH) in morbidly obese adolescents undergoing evaluation for bariatric surgery.Methods: A cross-sectional stu...

Celiac disease (CD) is a frequent cause of malabsortion in childhood and affects calcium and vitamin D absorption.Aim: Analyze the vitamin D levels and bone mineral density (BMD) at diagnosis in patients affected with CD, and the influence of the age of diagnosis in the clinical presentation.Patient: 52 patients (female: 26) were evaluated.Results: The percentage with vitamin D deficiency (<20 ng/ml) was ...

The aim of the present study was to evaluate bone mass and bone microarchitectural texture as assessed by trabecular bone score (TBS) modification at spine during childhood growth in girls.The study group was composed of 415 healthy girls aged between 2 and 17 years old. Height, weight and BMI Z-scores were evaluated and compared to The WHO Child Growth Standards. Pubertal stage was evaluated using Tanner score. The areal BMD (aBMD) was assessed...

Introduction: Fibroblast growth factor (FGF23) is a hormone derived from osteoblasts and osteocytes being involved in calcium and phosphate homeostasis, where serum iron (S-Fe) has been suggested as a potential mediator of FGF23 regulation. The aim was to determine whether iron status is a determinant of FGF23 in elderly men.Methods: The MrOS (osteoporotic fractures in men is a population based study of elderly men, in the Gothenburg part, (median age of...

Objectives: The present study aims at evaluating bone mineral density (BMD) in a population of children with Neurofibromatosis type I (NF1), with particular focus on changes occurring during growth and pubertal development, trying to understand the magnitude and timing of onset of BMD impairment in this multisystemic and progressive disease, the latter poorly defined so far.Methods: Bone metabolic markers (total calcium, phosphorus, bone alkaline phospha...

Introduction: Conventional treatment of X-linked hypophosphataemic rickets (XLH) involves administration of oral phosphate and vitamin D analogues. An important treatment goal is to heal rickets which is assessed by normalisation of serum alkaline phosphatase (ALP) levels and resolution of radiological signs of rickets.Objectives: To determine the usefulness of serum ALP in assessing disease severity on wrist and knee radiographs as determined by rickets...

The aim of this study was to evaluate the trabecular bone score (TBS), bone mineral density (BMD) and body composition in women of various ages.Materials and methods: 494 women aged 41–89 years (mean age, 63.6±0.4 years; mean height, 1.61±0.003 m; and mean weight, 74.0±0.6 kg) were examined. The patients were divided into the following age-dependent groups: 40–49 years (n=35), 50–59 years (n=130), 60–6...

Background: Cardiovascular disease is the leading cause of death in pediatric (ped) and adult ESRD patients. Left ventricular hypertrophy (LVH) is an independent predictor of mortality in ESRD. Besides traditional risk factors, such as high BP & fluid overload, high plasma FGF23 is associated with LVH in adult ESRD patients. Little is known about Kl, the renally produced cofactor of FGF23 for phosphorus (P) homeostasis. We studied ped HD patients for risk factors for LVH, ...
