Objective: To investigate the relationship of frailty with vitamin D in community dwelling elderly women.Materials and methods: A retrospective cross-sectional study was performed on women over 60 years who were not using vitamin D supplementations. Frailty status was defined using Fried’s criteria: weakness, low walking speed, low physical activity, weight loss, exhaustion. Participants were classified as robust, prefrail and frail if they scored 0...

Objective: To assess the incidence and distribution of hip fractures by sex and age among individuals over 40 years in Lithuania in 2010.Materials and methods: This population-based study was performed collecting the data from all orthopaedic-traumatology inpatient departments in Lithuania. The case histories of Lithuanian residents over 40 years, who had suffered a hip fracture in 2010, were examined. Subjects with primary hip fracture (ICD-10 codes S72...

Background: Observations in rodents suggest that osteocalcin (OC) participates in glucose metabolism. Data from human studies are inconclusive and it remains unclear whether OC is simply a marker of bone turnover (BTM) or if it also mediates interactions between the skeleton and glucose homeostasis. This study determined the responses of BTMs, including OC, to oral glucose tolerance test (OGTT) in obese and normal-weight subjects.Materials and methods: P...

Background: Hypocalcemia presenting in adolescence is rare. Most common etiology is autoimmune hypoparathyroidism. Pseudohypoparathyroidism (PHP) is a rare group of disorders characterized by end-organ resistance to parathyroid hormone (PTH), and other hormones, such as TSH, with or without features of Albright’s hereditary osteodystrophy.Case presentation: A 14-year-old boy presented complaining of fatigue and spontaneous carpal spasms in associati...

Patients with chronic inflammatory diseases such as psoriasis are at high risk for developing osteoporosis. Psoriatic arthritis patients exhibit bone loss caused by increased bone resorption through activation of osteoclasts. However, it is not clear whether psoriasis can lead to bone loss in the absence of arthritis. Using mouse models with skin inflammation as well as psoriasis patient samples, we show that increased circulating IL-17A from the inflamed skin triggers bone lo...

Background and aims: Vitamin D supplementation has the potential to alleviate the cardiovascular damage in diabetic patients. The present study was designed to evaluate long term impact of high doses of vitamin D on arterial properties, glucose homeostasis, adiponectin and leptin in patients with type 2 diabetes mellitus.Methods and results: In randomized, placebo-controlled study 47 diabetic patients were assigned into two groups: Group 1 received oral ...

Background: Osteoarthritis (OA), the prevalent joint-affecting disease characterized by cartilage damage, is the leading cause of disability in adults and contributes to the excess of morbidity and healthcare costs. We performed the current trial to evaluate biomarkers, specifically adiponectin in serum and synovial fluid, associated with cartilage damage severity assessed by arthroscopy, in patients with symptomatic knee osteoarthritis.Methods: The 40 s...

Background: Identification of risk factors may help us to understand the pathogenesis of osteoporotic hip fracture as well as to formulate development of better diagnostic, prevention and treatment strategies. The present study was designed to determine the impact of multiple metabolic risk factors such as markers of systemic inflammation (C-reactive protein), body iron stores (ferritin), insulin resistance (HOMA-IR) and bone remodeling (osteoprotegerin), for the prediction of...

Low bone mineral density (BMD) and an increased rate of both peripheral and vertebral fractures have been observed in patients with Duchenne muscular dystrophy (DMD). However, studies specifically addressing bone metabolism, BMD and fractures in this disease are still very few.Our ongoing multicenter, prospective study is aimed to identify the characteristics of the DMD boys with a higher risk of bone loss and fractures, through the evaluation of bone tu...

Low bone mineral density (BMD) and an increased rate of both peripheral and vertebral fractures have been observed in patients with Duchenne muscular dystrophy (DMD), but studies on bone metabolic alterations in this disease are still very few.We are now presenting the preliminary findings of an ongoing multicenter, prospective study aimed to identify the characteristics of DMD boys carrying a higher risk of bone loss and fractures, through the evaluatio...
