Objectives: Low bone mineral density (BMD) and increased frequency of peripheral and vertebral fractures have been reported in boys with Duchenne muscular dystrophy (DMD), but studies on the determinants of low BMD are still very few. We are currently carrying out a multicenter, prospective study aimed to identify the characteristics of DMD boys with a higher risk of bone loss and fractures.Methods: Forty-two DMD boys (mean age 9.9±3.3 years) underw...

Introduction: Reduced bone mineral density [BMD] and increased fracture risk are common complications in all conditions characterized by severely reduced physical activity and/or requiring long-term glucocorticoid [GC] treatment, including Duchenne Muscular Dystrophy [DMD].Objectives: The RisBo-DMD study (EudraCT 2011-005745-12) is a 24-month prospective multicenter study, aimed at identifying DMD patients at higher risk of fractures and improving the bo...

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...

The femoral neck fractures (FNF) are one of the most common non-traumatic fractures in elderly people. Frequently the patients with fractures of this localization need surgical treatment and long-term rehabilitation. It’s widely known that FNF in patients with rheumatoid arthritis (RA) occur more often than in the population.Background: To determine the frequency of FNF in patients with RA and to characterize the patients with RA and with FNF at the...

Objectives: Denosumab (Dmab) is a monoclonal antibody targeting RANKL administered by sub-cutaneous injection. Given its convenient mode of administration, our goal was to assess the safety and efficacy of Dmab compared to intravenous zoledronic acid (ZA) in pediatric osteoporosis.Methods: In this one-year pilot study (NCT02632916), children 4–16 years with low-trauma fractures due to osteoporosis were randomized 1:1 to receive ZA 0.025 mg/kg or Dma...

Objectives: Denosumab (Dmab) is a monoclonal antibody targeting RANKL administered by sub-cutaneous injection. Recent reports have raised concern about the ‘rebound phenomenon’ (hypercalcemia and increases in bone turnover markers, BTM) following Dmab in adults, and during treatment in children with osteogenesis imperfecta. The purpose of this report was to explore this phenomenon in children with osteoporosis associated with lower bone turnover.<p class="abstext...

Objectives: The aim of the study was to establish features of macroelemental composition of the dentin in mature male rat’s mandibular incisors with biogenic hydroxyapatite, implanted in the proximal part of tibial shaft.Material and methods: One hundred and twenty-six mature male rats were divided into three groups: 1st group – intact animals, 2nd group – animals with the pit defect applied on the proximal part of tibial shaft (systematic...

Background: Stuve–Wiedemann syndrome (SWS, OMIM 601559) is a severe autosomal recessive condition characterized by bowing of the lower limbs with cortical thickening, wide metaphyses, abnormal trabecular pattern and camptodactyly. Additional features include dysautonomia symptoms with temperature instability, respiratory distress and sucking/swallowing difficulties in the first months of life.Most SWS cases do not survive beyond the first y...

Rheumatoid arthritis (RA) is marked by the persistent inflammation and osteodestruction, causing progressive disability. Osteoclast progenitors (OCPs) represent a subpopulation of peripheral blood monocytes and have been shown to be present in healthy subjects and arthritic patients. The aim of our study was to determine the phenotype, frequency and osteoclastogenic potential of OCPs in the peripheral blood and synovial fluid of RA patients in response to anti-TNF therapy....

There is discussed an interrelation of BMD, progressing of erosive and destructive changes in hands and feet with development of vertebral deformations in rheumatoid arthritis (RA).The aim: To receive data on bone mineral density (BMD), erosive and destructive changes in hands and feet and vertebral deformations in patients with RA.Materials/methods: In this research, it was included 106 women, with RA, age 23–69 years. In all...
