Purpose: Systemic sclerosis (SSc) is a rare inflammatory rheumatic disease that has been associated with an increased risk of low bone mineral density (BMD). However, data on risk factors associated with bone loss in SSc are scarce. The objective of this study was to investigate the prevalence of and the risk factors for low BMD in patients with SSc.Methods: Cross-sectional data of 61 patients with SSc were collected. BMD in the lumbar spine, total hip a...

Background: It is known that one of the features of rheumatoid arthritis (RA) is a generalized bone loss, therefore important tasks for the physician are timely evaluating of the risk of fractures and approving osteoporosis treatment in patients with RA.Objectives: Through the Programme of the Russian Association of Rheumatology for the diagnosis, prevention and treatment osteoporosis (OP) in patients with RA we evaluated the 10 year probability of major...

It is well-established that in vitro differentiation of embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) can recapitulate embryonic development through germ layer induction, enrichment and expansion of specific lineages. We have used PSC technology and developed a novel, mESC differentiation system for investigating the mechanisms of chondrocyte and osteoblast lineage commitment and differentiation. This step-wise, serum-free protocol uses specif...

The main cause of the bone destruction in rheumatoid arthritis (RA) is a destructive act of aggressively growing pannus, growth and angiogenesis of which are caused by the proliferation of fibroblasts in the synovium (S) due to the activation of fibroblast growth factor (FGF).Objectives: To reveal relationships of FGF with ultrasonic and arthroscopic and proliferative-destructive histological figures in RA.Methods: Complete compreh...

Objectives: There are conflicting data on the skeletal health of patients with perinatal HIV. We aimed to evaluate the bone profile of a paediatric population followed in a reference centre for perinatal HIV.Methods: The following data were recorded: dietary calcium intake, extra-curricular exercise, fracture history, medications and comorbidities. All patients were assessed for growth and skeletal deformities. They underwent laboratory tests:CD4 count, ...

Geroderma osteodysplasticum (GO) is a rare autosomal recessive connective tissue disorder characterised by progeria like facies, wrinkled lax skin, joint hypermobility, congenital dislocation of hips and propensity to fragility fractures. In the past 25 years, five patients (three females and two males) diagnosed with GO were referred to our Paediatric metabolic bone service for assessment and management of secondary bone problems. All five children were born to consanguineous...

Clinical trials involving drug therapies for postmenopausal osteoporosis typically compare effects of the active drug combined with vitamin D (vit D) and calcium (Ca) vs vit D and Ca supplementation on its own. Bone strength is estimated based on the amount of bone, frequently expressed as bone mineral density determined by dual X-ray absorptiometry, and quality of bone, hardly measured in clinical practice.The purpose of the present study was to compare...

Objective: To evaluate musculoskeletal development using pQCT in children with coeliac disease (CD) on gluten free diet (GFD) compared with age and gender matched healthy controlsMethod: 38 children (18 males) with CD on GFD for a duration of 3.6 years (0.6, 12.5) underwent pQCT at 4%, 38 and 66% tibial sites. Bloods were collected in CD children only. Results reported as median (range).Result: Median TTG was 1.8 IU/l (0.1, 114) wi...

Background: Treatment with multipotent mesenchymal stromal cells (MSC) has the potential to ameliorate mesodermal disorders.Objective: To treat severe osteogenesis imperfecta (OI) with fetal MSC.Methods: Ten years ago, we treated a fetus with OI type III (COL1A2: c.3008G>A, p.Gly1003Asp) in utero with fetal HLA-mismatched MSC. The procedure was uncomplicated. At the age of 4 months i.v. pamidronete treatment was starte...
