Background: Osteoporotic fractures are a major cause of disability and results in extensive utilization of health care resources. The history of previous fractures increases the risk for future fragility fractures.Subject: To describe the diagnostic therapeutic protocol of our tertiary care clinic dedicated to the osteoporosis (OP) treatment. To estimate the use of effective therapies for OP in those patients at highest risk for future fracture.<p cl...

Introduction: Bisphosphonates are the first-choice treatment for osteoporosis. However, the efficacy observed in clinical trials may not be realized in a real-life setting, partly due to poor adherence to therapy, with a significant worsening of clinical outcomes. The aim of this study conducted on an outpatient cohort is to quantify the adherence to the osteoporosis treatment in real practice setting and to identify the factors that may affect it.Materi...

Introduction: Evidence in literature shows how is useful to use antiresorptive drugs such as bisphosphonates, in severe osteoporosi severe after PTH (1–34 or 1–84) treatment.Methods: This study was divided into two parts: the first one analyzed BMD changes by DXA at the lumbar and femoral and serum osteocalcin and β-CTX, monitoring their performance after 6, 12 and 18 months in 71 women with severe postmenopausal osteoporosis, treated for ...

Introduction: Teriparatide is a potent anabolic drug that has demonstrated efficacy on fracture risk reduction in women with severe postmenopausal osteoporosis. Denosumab, designed to inhibit RANKL (RANK ligand), is a fully human MAB for the treatment of osteoporosis. BMD changes, measured by DXA, is an established tool for monitoring the effects of anti-osteoporotic therapy. Our purpose is to compare teriparatide vs denosumab efficacy on hip BMD variations, in postmenopausal ...

Introduction: Denosumab, a fully human monoclonal antibody to RANK ligand, effectively reduces bone resorption by inhibiting RANK-L binding to RANK. We aimed to evaluate the efficacy of denosumab in post-menopausal women, by monitoring the evolution of different parameters of bone health: T-score, morphometry, osteocalcin and β-Ctx.Methods: A 34 women with severe postmenopausal osteoporosis, characterized by multiple vertebral fractures wer...

Arterial stiffness or pulse wave velocity (PWV) is increasingly recognized as a strong predictor of future cardiovascular events and all cause mortality. Literature date indicate a relationship between vitamin D (25-OHD) deficiency and arterial stiffness in isolated systolic hypertension (ISH), but it is still unclear how 25-OHD deficiency may contribute to functional changes of the arterial wall in hypertensive patients. This study aimed to evaluate the relationships between ...

Introduction: Vertebroplasty (VP) and ballon kyphoplasty (BKP) are used in the treatment of the vertebral compression fractures (VCF), that usually result in a typical wedged deformation. It is still under debate which technique is the best, in terms of efficacy, costs, and safety, mainly about the risk of a adjacent new fractures. The aim of this study is to evaluate the biomechanical outcome of vertebroplasty and kyphoplasty by a computational comparative analysis with finit...

Long-term use of pharmacological treatments of osteoporosis is currently a controversial subject within the scientific community.The aim of this work was to study the effects produced by a preventive long duration treatment of strontium ranelate and zoledronic acid on bone mass and remodelling when they are administered to ovariectomized rats.Sixty female albino Wistar rats were divided into four groups (n=15): SHAM group ...

Introduction: Although systemic lupus erythematosus (SLE) has traditionally been considered a disease of women, men may also be afected. Male osteoporosis is increasingly recognised. Several studies have reported that mean bone mineral density is significantly reduced in SLE women patients and most of them have low levels of vitamin D. The aim of our study is to analize this situation in men.Objectives: Determine 25-hydroxyvitamin-D (25OHD) serum concent...

Many pharmacological treatments have been developed in order to prevent or treat postmenopausal osteoporosis. There is not any study in the literature comparing long-term treatments of osteoporosis. The aim of this work was to studythe effects of long-term prevention treatment with zoledronic acid (ZA) and strontium ranelate (SrR) on bone microstructure in ovariectomized rats.Sixty 6-month-old female Wistar rats were used in this study and divided into f...
