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...

Objective: To study the trends in prescription of different anti-osteoporotic drugs (AOD) in the UK population aged 50 years or above from 1990 till 2012.Methods: Retrospective observational study using the CPRD data link representative for the total UK population. The incidence of prescription of a specific AOD was calculated by dividing the number of prescriptions by the total person-years (py) of follow-up.Results: AOD prescript...

Introduction: Research on biomaterials for bone regeneration generates a plethora of new biomaterials requiring evaluation with reliable and comparable methods of biocompatibility and functionality for clinical translation. To reduce the burden of in vivo assessment, there is a need for refined in vitro assays that are predictive of in vivo outcomes. This retrospective study correlated in vitro results with in vivo outcomes observed...

Atypical femur fractures (AFF) have been associated with antiresorptive therapy. In a retrospective case-control study, we identified AFF using ASBMR 2013 criteria. Femoral shaft fractures were identified using ICD9 codes. We screened 1479 radiographs. Radiographs were excluded for high-energy trauma, tumor, or periprosthetic fracture. Two radiologists blinded to treatment scored 482 radiographs for AFF features, and jointly adjudicated discrepancies. The required AFF feature,...

Urolithiasis is characterized by formation and retention of solid crystals within the urinary tract. There are numerous causes that may lead to urinary stone formation. However, kidney stones are mostly composed of calcium oxalate that predominantly generates free radicals that are toxic to renal tubular cells.The aim of the study is to explore the toxic effect of oxalate to renal epithelial cells and to explore possible effects of antioxidants on its in...

Objectives: Progressive heterotopic ossification in fibrodysplasia ossificans progressiva (FOP; OMIM #135100) begins in childhood and leads to irreversible restriction of movement, functional impairment, and shortened life-span. Baseline data from an on-going, global, 3-year, natural history study (NHS) describe FOP disease characteristics, and retrospective flare-up history, causes/symptoms, and outcomes.Methods: Data from 101 subjects (recruited from 2...

Objective: FOP is a rare, severely disabling disease characterized by episodic flare-ups and accumulation of heterotopic ossification (HO) leading to restricted movement, physical disability, and early death. Data from two Phase 2 interventional studies and one natural history study (NHS) were used to evaluate whether palovarotene could reduce HO following an FOP flare-up.Methods: HO volume at the flare-up site was determined by CT at baseline and 12 wee...
